Download Custom Firmware ipsw files for iPhone 2G, 3G 3.1 [Windows/Mac] , Error 1600 Solution Updated

15 September 2009 238 Comments

iPhone 3.0 Jailbreak Unlock

UPDATE : A new version of custom firmware 3.1.2 for iPhone 2G/3G/3GS is now available here!

UPDATE : If you get a 1600 error while trying to restore to a custom firmware here, try this.

iPhone 2G and 3G users can now safely update to 3.1 firmware without updating the baseband (for unlock). If you are not the one to download all the various files and just want the ultimate result, these files are waiting for you to download! If you rather want to start from scratch, download Pwnage 3.1 tool for Mac.

  • Caution #1 : Please proceed further only if you have an iPhone 2G/3G. iPhone 3GS files can be downloaded here.
  • Caution #2 : A restore is going to wipe the iPhone clean. Hence, please backup your iPhone using iTunes and then proceed.

More info about these custom firmware files : Has factory boot logos (Apple and restore cable), Only Cydia, No Icy, Default root partition…

Step 1a) Download Files for iPhone 2G (Please read the following carefully)

OR


Step 1b) Download Files for iPhone 3G (Please read the following carefully)

OR

Step 2) Join the downloaded files

  • The files downloaded above have an extension .001 and .002. They need a special opensource (free) software HJSplit to join.
  • Download HJSplit to join both the files – Link for Windows Computers here and Macs here.

Step 3) Restore the firmware in iTunes 9.1

  • You should now have the respective firmware file with an extension .ipsw . Please follow the steps in order.
  • Launch iTunes and connect the iPhone to your Mac / Windows computer.
  • If you are aware of DFU mode, proceed further. If not, watch this quick video and pay close attention to the steps to achieve DFU mode.
  • Turn your iPhone off. Press and hold the Home button and the Power button at the same time for 10 seconds.
  • After exactly 10 seconds release the Power button. Continue holding the Home button until iTunes pops up a message saying that it has detected an iPhone in recovery mode.
  • The iPhone will show you a blank screen (black).
  • Click on ‘Ok’ to the prompt displayed and hold Option key on your Mac and then hit Restore button. For Windows, hold the shift key and then hit the restore button. In the dialog box that pops up, browse the downloaded custom firmware file.

Step 4) Give it few minutes to perform the restore. Once the iPhone is up and running, proceed for software Unlock using Cydia. Follow this guide to install Ultrasn0w to software unlock your iPhone 3G. iPhone 2G is already unlocked with this custom firmware!

You are now good to go! Post a comment if you are stuck at any of the steps described above.

  • iLikeMyiPhone said:

    Please make sure you are using 2G firmware and not 3G. Did you join the 2 files 0.001 and 0.002? Is the resulting file .ipsw? Is it activated or notactivated firmware that you downloaded?

    I have the same problem.while restoring 1600 error coming. . My phone stuck as the black screen .it is not at alla turning on also.

    3.1 restored successfully! Unlocked with Ultrasn0w offline method because … wifi doesn't works!!! :( Like for previous firmware 3.0 my wifi cannot find any network!!! :( Help pleaseee!

  • iLikeMyiPhone said:

    So wifi didn't work for 3.0? If it is a hardware issue, it cannot work. Is wifi setting greyed out or it just doesn't find the network?

  • t j said:

    I got a phone that was already upgraded to 3.1 via apple update. I use Pnwage to jailbreak it, then tried ultrasn0w to unlock it, and all seemed to go fine, except when I put my sim card in, no network is detected. So does this work if the baseband was updated?

  • iLikeMyiPhone said:

    Sorry to hear that. There is little we can do about unlock at this time…3.1 is not unlockable yet…

    shoot,, any guess how long I’ll have to wait? days, weeks, months? What about the software for sale that claims to unlock 3.1, will that work for me? Thanks!

  • crockard said:

    Cannot find the network, but is not greyed, I have mac address for WiFi and Bluetooth (bluetooth works properly).
    I don't think it is an hw issue, because WiFi worked well with 2.2.x until I had upgraded to 3.0. Unfortunately I have bootloader 5.9 and I cannot downgrade the baseband :(
    Do you have others ideas?
    Thank you a lot!

  • iLikeMyiPhone said:

    Well, if that is the case, turn off bluetooth and then try connecting to a WiFi hotspot. I have read about reports with conflicting Bluetooth and WiFi. Baseband upgrade is not causing the issue here…. Try a different hotspot (public hotspot…)

  • ronne said:

    hello there… im new here and my iphone was given to me my brother and i dunno where from or what the original carrier was…

    accidentally / purposefully since i thought it was a simple upgrade… i upgraded my 3.0 to 3.1 using itunes 9.0…
    then… i lost my signal and the screen popped a.. sim card failed. so i got scared and then pressed restore…

    and now… my iphone displays ITUNES then connect USB and then slide for emergency ( i think it went to the activation )

    I tried to UNLOCK it; but I was stupid enough to install firmware 3.1 on it.
    Now the phone shows a "No SIM card installed error" screen; and the only thing I can do is make emergency call. That's it.
    I tried to turn it on and off but it doesn't do anything. What should I do ? Please HELP! I'm desperate now.

  • David said:

    Hey Kiran,
    Is it necessary to put your phone in the DFU mode before restoring the custom ipsw? I always do the Shift+restore (windows) when the phone is in normal on mode.

  • iLikeMyiPhone said:

    DFU is recommended. If your iPhone is already pwned, you can use just restore in restore mode!

    thanks you sooooooo much…. i did it… i was able to have my fone useful again but… i dont have signal none at all do you think i can do something about now… as of now? i used redsnow after i downgraded to 3.0 then now i have both icy and cydia istalled but no signal … will ultrasnow work? where do i DL it? my version is now 3.0 (7a341) and modem firmware of 05.11.07

    thanks again iphone guru!

  • iLikeMyiPhone said:

    Please refrain from any such software. 3.1 baseband cannot be unlocked, period. ETA is hard cos' Apple tightened their code this time around… Lets hope!

  • iLikeMyiPhone said:

    Unfortunately, 5.11 baseband cannot be unlocked :(

    I am baffled, how did you get 5.11 baseband with 3.0? Did you upgrade to 3.11 and then downgrade to 3.0??

  • ronne said:

    because… i didnt know my iphone unlocked i thought it was released by the official carrier in the country where im an in…i updated it from 3.0 to 3.1

    i lost my signal . so i pressed restore… then my iphone went back to activation… and so what i did is follow the instructions in one of ur blogs to downgrade to make iphone jailbroken… but i used 3.0 (not 3.01 as what was instructed) after that i used redsnow then voala… its working again but no signal and… i dont know why… and my band changed… i dunno….

    i hope there will be a solution for this…

    but thank you… you were really helpful… ill keep on looking here incase here are updates… and i hope you can help me with this last problem… thanks…

    ur so nice :)

  • Hendo said:

    i juts want to jailbreak it. it was in DFU mode

  • iLikeMyiPhone said:

    Well, if it is in DFU mode and you get 1600 error, try rebooting both iPhone and PC/Mac.

    On a Mac – Before creating the custom ipsw, delete anything that you can find in ~/Library/iTunes/Device Support

    On a PC – Delete device support files in iTunes folder (restore files)

  • Hendo said:

    okay so u mean like restart them both and delete all the other support files that i had in the itunes folder before?

  • iLikeMyiPhone said:

    Yep exactly! Delete the restore files under iTunes.

    Thanks a lot! ill try it out and tell you how it went :)

    Does anyone have a solution for the "No Service" problem with iPhone 3g baseband 4………since i updated my ultrasn0w I dont get any signal

  • Seb said:

    04.26.08

  • iLikeMyiPhone said:

    Perfect! You are on the right track for unlock. Make sure you turn off 3G. Reboot iPhone, ultrasn0w should work, also make sure you install any updates that show up in Cydia…

  • Hendo said:

    idk why but i did all of that and delete the restore files from itunes and it still doesnt work….. do i have to delete the Itunes update logs as welll?

  • Seb said:

    hmm..Now it says "No sim"..never happend before..i'll try to reset my phone and jailbreak it again then use ultrasn0w…does it sound like a good idea? or will it automaticly update to the 3.1 firmware?

  • iLikeMyiPhone said:

    Hmmm, well, uninstall ultrasn0w and install it again from Cydia. If you turned your 3G off already, it should definitely work sinc eyou are on 4.26.08 baseband. Reboot and you will egta signal.

    If not, then yeah, carefully restore to 3.1 custom firmware and then unlock, not 3.1 stock firmware btw …

  • Seb said:

    I may say that I installed some deb. file a while ago in the folder var/root/media/cydia/autoinstall folder via iFile, heard this from another forum…Do you think that this may cause a problem?

  • iLikeMyiPhone said:

    Never tried it. But yeah, try the above mentioned steps (comments) , it should definitely work!

  • Seb said:

    I reinstalled ultrasn0w and now it doesnt say no sim, now its just bars like dots ….. so i don not have signal.. If I press reset iTunes say do you want to reset and update your phone? Well do I? Is there a jailbreak and a working unlock for the 3.1 firmware?

  • Hendo said:

    oh okay it is in DFU. it has a black screen :o and i have no idea y it doesnt work… and i tried downgrading ones lol it was a different error tho.. but thanks if i need anymore help ill let u know.

  • Hendo said:

    How about backup folders?

  • iLikeMyiPhone said:

    You can leave them alone. They are backups..

  • Hendo said:

    would taking out or leaving the sim card in do anything? >.> such a pain and i have no idea why it doesnt work….

  • iLikeMyiPhone said:

    SIM card shouldn't be an issue at all…

  • Hendo said:

    sighhh i guess then ill have to wait or something >.>

  • iLikeMyiPhone said:

    So you tried everything I mentioned here and it still shows 1600 error?

  • Hendo said:

    i did the restore mode before…. it messed it up so bad that i had to go download the official one >.> oh did i mention that it is my first time jailbreaking it? i remember hearing that there was an extra step on the pwnagetool but i cant use it since i have PC

  • kkiran said:

    Hey! So sorry for the delay. Replied from iPhone and it didn't deliver the comment!

    DFU mode is required if your iPhone has never been pwned before.

    Restore mode or DFU mode if you are not sure if your iPhone is pwned / jailbroken!

    Shift + Restore works fine w=if your iPhone is already jailbroken and are restoring to a custom firmware….

    Sorry for the delay in responding. IF you are using 3G then download the files for 3G! (the second set of files in step1b)…

    I have a IPhone 3G 16gig that i have officially updated to 3.1 via ITunes as my phone is factory unlocked and baseband updates are not an issue for me. My question is if I use the non activated firmware posted above will it still jailbreak my phone ok and leave my baseband as is or is it still going to try and keep old baseband wich i no longer have or need ?

  • iLikeMyiPhone said:

    Hi! You are sailing in a perfectly safe boat ;)

    Go ahead and use a Non activated firmware since factory unlocked iPhones don't need activation. The baseband is not updated but since you have updated it already it doesn't make a difference. Go for it!

    You will have to use redsn0w to unlock it. Follow the last link towards the end of the post to unlock…

    » Try rebooting both iPhone and PC/Mac
    also tried a new itune install on 3rd pc that had just bean formated and windows xp installed so it was clean system still get 1600 error
    i enter dfu mode run the restore through itunes my screen flashes as though its about to start the restore then after around 20-30 seconds i get the 1600 error
    still get same error unable to restore

  • hesky said:

    I EVENTUALLY GOT IT TO WORK UPGRADED TO 3.1 7C144 after a lot of messing update with restore mode now but i have no carrier dosnt show in general and under network it says not available any ideas
    got carrier workin after ultrasn0w but all i get now is this network ristricted regardless of what sim i insert into the phone are well a least its a bit nearer than no service lol

  • PrincessV said:

    how about turbo sims? do you think they will help thanks

    Nope, stay away from those turbo sims…

  • mrpolo said:

    yes i tried restoring in normal mode everytime i get a 1604 error i delete the file like u said in ur 1600 error solution then uninstalled itunes then re installed it and tried to restore but same thing. does it matter that im using a firmware thats for other carriers so i guess its hacktivated.

  • iLikeMyiPhone said:

    Nah, either of the firmware should work just fine. Did you restart computer, iPhone and then try DFU mode? What OS is it?

  • mrpolo said:

    I didnt restart my computer im about to do that now… also my OS is vista 64 bit and as far as DFU mode i cant enter it because my home button doesn't work

  • iLikeMyiPhone said:

    Oh. It can be a tough bet without Home button :( Please check downloads section here and try earlier unlock tools, ZiPhone or other Windows tools. I wish you luck… Out of warranty is it?

  • mrpolo said:

    yeaaaa its out of warranty and restarting didnt help :( thanks for the hep though

  • kiran said:

    Not a problem! You may have to replace home button, try craigslist… I opened it the other day, lil complicated but doable!

  • mrpolo said:

    my question is do you know of a way to put 3g iphone into dfu mode without buttons? my home button stopped working and that made it impossible for me to enter dfu mode. Im on official 3.1 fw and i have vista… the reason i want dfu mode is so i can restore to a jailbroken 3.1 and get an app from cydia that acts just like a home button. thanks for your time Also my itunes is 9.00

    hey i just followed all the steps and itunes successuflly restored the iphone but when the iphone turned back on it was still locked and it had the tmobile sign but all i could do was the emergency call, what do i do now? i have a 2g and using vista

  • iLikeMyiPhone said:

    Hi! You must have used the NotActivated firmware. It is intended for legal iPhone contracts. If you do have legal iPhone contract, connect your iPhone to iTunes and it should activate (needs ATT sim).

    Since you are using T-Mobile sim, you must use activated firmware instead.

  • SethA said:

    i actually did download the activated firmware, and it went through everything and it said successuflly restored and all that stuff. it just brought me back to the itunes logo and the usb with the slide to unlock and emergency call. What should i do? i can receive calls and texts but cant do anything

  • iLikeMyiPhone said:

    So sorry to hear that. Not sure what might have caused this. Would you restore to the Activated firmware again? No one reported this issue before and more than 1500 people downloaded the 2G Activated firmware files!

I have now msg "unrecognize SIM". I've read through many posts/comments but still couldn't figure out why I cant work things out.

  • iLikeMyiPhone said:

    Oops, I am so sorry for the confusion, you have to use the activated firmware if you don't have iPhone contract.

    Both the firmware have the old baseband anyway, so even if you mistakenly use either of the firmware, you can still use the other one.

    But I checked the SETTING, myVersion is 3.1 (7C144) n ModemFirmware is 05.11.07.
    My queries: (i) by reading ur post, I presume UNLOCK is NOT possible rite [due to firmWare]… Pls confirm; (ii) reason I upgraded to 3.1 was to get the Compass App. BUT why is it not there? [since now version is 3.1]. Any idea?
    Thanks

  • iLikeMyiPhone said:

    i) Unfortunately, it cannot be unlocked since you restored via iTunes tot he stock 3.1 firmware from Apple

    ii) Compass app is available only on iPhone 3GS cos' it requires specific hardware for it to work.

    5.11

    Well I screwed up and missed the step that said "For Windows, hold the shift key and then hit the restore button. In the dialog box that pops up, browse the downloaded custom firmware file."
    So it downloaded it's own new firmware and restored and now it won't let me restore to the custom firmware to use T-Mobile. I held the buttons down again and got it back into recovery but holding shift key never lets me select custom firware. Am I screwed?

    Hey guys,
    I got a question about the 3.1 custom firmware. I got a iphone 3g with 2.2.1 and 2.30 baseband. I know that 2.30 baseband can't be unlocked so if i upgrade with the 3.1 custom firmware will it update my baseband to 4.26. i would like to unlock so i can use with tmobile. i run xp. please let me know. thanks again

    Hi Thomas. You did not upgrade the right way I believe. You have to upgrade to 3.0 firmware from iTunes (factory firmware, not custom firmware) and then try the custom firmware.

    Hi, i have an Iphone 2G which i have got unlocked earlier. I'm using it with AT&T Go Phone. I want to upgrade the FW to 3.1 on my 2G. Should i use "iPhone 2G 3.1 Custom Firmware Activated for Other Carriers"?? I plan to upgrade the Phone from Win XP. Will this custom firmware upgrade the baseband?

  • iLikeMyiPhone said:

    Use the NotActivated one, it should work if you are using ATT. 2G iPhones need not worry about baseband updates anymore! They stopped developing newer basebands for 2G iPhones.

  • Sharath said:

    Hi,
    Thanks your response!!.. I do not have any contracts with AT&T and 2G phone will not work on prepaid if locked for carrier. My requirement is to use my 2G iphone on AT&T Go phone (prepaid) while in the US and will be moving to india shortly. I should be able to put Sim card from other carriers (Vodaphone & Airtel) when i return. Now, could you please suggect me if "Activated for Other Carriers" will work for me? I suppose "Activated for Other Carriers" should work with AT&T also right?? Please suggest….

    Hey I was not able to do the DFU but I was able to load the firmware by holding the home button and plugging it in to iTunes.

    My problem is MMS still wont send. And I noticed there is no AT&T logo, but I do have a signal (E and 3G).
    When I check the About info, it says Not Available under Network….but it does say I have Carrier AT&T 5.6 and my modem firmware is 4.26.08

    I swapped my sim card back to my 2G to see if I could get a signal and I still could, the AT&T logo popped up…

    I called AT&T and they said it messed up my sim card when I put it back from my 3G to my 2G and "updated my carrier settings." They advised to get a new Sim card, even though i could still make calls, just not MMS.

    What should I do!

  • iLikeMyiPhone said:

    Best bet : Do a perfect 3.1 custom firmware restore and don't restore from backup. Now check for MMS ability. Forget about the ATT logo, it is a known bug.

  • danman2_2999 said:

    Thanks for the quick reply,
    yeah i agree, i dont care about the logo just the MMS functionality.
    so just reopen itunes and put the phone into recovery mode and re-shift + restore and choose this merged file i downloaded from this page?

  • danman2_2999 said:

    Oh no, still didnt work even though I didnt restore from backup!
    Should there be something in the "Network" field? it says NOT AVAILABLE.

    Also, originally i had my 2G then my friend gave me her 3G so i just swapped the sim card. When I initially called the AT&T lady said the problem was my plan was set up for the 2G not the 3G. But when I chatted with livechat they helped reset the IMEI settings and told me to get the new sim card, which did not help.

    I am not sure what to do!

  • danman2_2999 said:

    Could my problem how my plan is set up?
    My plan was set up with the 2G and I just swapped sim cards in about June to my new 3G. Could they be blocking my MMS cuz they show I am paying for 2G service?

    You may try the Unactivated firmware since you are on AT&T already. It should get the signal even without a plan. In the worst case if it doesn't work, you can then try the Activated firmware but it is highly unlikely for it to not work.

  • danman2_2999 said:

    Did you have an original 2G (and data/txt plan) and end up grabbing a 3G without a new contract and not tell AT&T?

    I did, my friend gave me his "old" 3G when he got the new 3GS, so i swapped my sim card from my 2G to my 3G, thinking that all the features wouldnt work, but they did! that was this summer…..until 3.1 update.

    I did the above, however I put the phone in recovery mode (holding home for a few seconds then attach USB with iTunes running) which worked, rather than DFU mode. No MMS. Failure everytime and I would receive viewmymessage.com txt. So I chatted once, lady reset my IMEI number and told me my sim card was bad, so I grabbed a new one and still same problem. I called and a nice girl said "sorry! there was some provision blocking your account, I took that off and now MMS will work." She sent a test pic and it worked! For a day! Then I called back and said wtf! and the next girl was nice and said "sorry! her she must not have saved the settings! I will reapply what she did." She sent an MMS and it worked! For a day again….the next day i called saying wwwwwwwtfffff and i got transfered to tech support, and they told me right away it was because my plan was for a 2G, and that I needed to upgrade to the 3G plan ($15 more) in order for MMS to work…I was pissed and said "no way, I was told already blah blah" and they didnt give a crap!

    Bottom line….if you had an original 2G and then put your sim card in a 3G, or you have a 2G data plan, dont expect MMS to work!

  • danman2_2999 said:

    If AT&T believes you have a 2G, or your data or txt plan is for an original 2G phone, then MMS will not be allowed.

  • iLikeMyiPhone said:

    Interesting! Yeah, that is the downside of not signing up for an iPhone 3G plan. Swirly MMS?

  • danman2_2999 said:

    I tried swirly as well, I told them I swapped my sim card from my iphone to my older razor so I needed MediaNet to work, but they finally told me they wouldnt do that for the iphone.

  • iLikeMyiPhone said:

    Stupid ATT! But yeah, what would they do if you put the sim in your other MMS phone for few days and once MMS works – swap it out? They are being too crazy lately…!

I am downloading 3.1 Activated Custom Firmware and going to combine them and do a Shift+Restore update….OK for the question(s). Should I re-use RedSn0w to Jailbreak and unlock my phone? I saw a comment a few weeks about 5.11 basebad being unlock able, will this be an issue with mine (not sure if 5.1 and 5.11 are the same)? Pretty much I want a simple-ish answer,lol.

Im just worried about locking my phone, as I do not have a back up. Thank you very much for any info.

    So I told myself to just do it and I did. The only thing is when i plug my phone into iTunes it says I have 3.1 and not 3.1.2 because it asks if I want to upgrade. Any advice on that? Also Cydia told me some of my repos are not working…and my APN is gone and have no internet…that i can fix with an APN changer but still just curious on why that happens and why does it not say 3.1.2. The new FW says 3.1 (7C144) // Carrier ATT&T 5.0. So I guess it also downgraded my baseband.

    You have to join downloaded files. Did you follow each step fully?

    Hi , Actually I was having the same problem I tried ultrasnow but it didnt work and I tried everything but there was NO service. So then i read somewhere that download fuzzyband and if ur bootloader is 05.08 then you can do it. So i tried that …luckily my bootloader was 05.08 and then I downgrade the firmware from 05.11.07 to 04.26.08 after that I reinstall ultrasnow and it worked !!!

    Yeah…Don't, DON'T, DO NOT enter it into DFU mode. There's no need. And that's why people keep getting the 1600 error messages. If your phone is already IN DFU mode, just reverse it by hitting home and power for ten seconds again. It's quite simple. then just restore it normally. You don't have to do any sort of fancy button pushing, it'll restore right through itunes normally. THANX for the firmware upload tho!!!
