    Is the redsn0w 0.9.4 for windows still available? both links on this page don’t work. Can I use a new version of redsn0w to upgrade to 3.1.3?

    Many, many thanks. Worked like a charm. Quick installation without any hickups. Instructions were clear even though i am not the most informed on lame apple products… at least my uncle will be a happy camper πŸ˜€ Well done.

    Thanks a lot, it worked for my iPhone 2G (aka iPhone EDGE)!!!

    I installed the last version of iTunes, let it restore the iPhone firmware (iTunes installed the firmware 3.1.2).

    Then had a hard time in finding the RS version (dead links), I googled and managed getting the version 0.9.4 which worked fine.

    I also encountered an error in launching the Redsn0w application. The application got stuck during the first steps (“has encountered a problem and needs to close” error message). I solved the problem by allowing the files to pass the firewall (firmware files 3.1.2 and 3.1.3, plus Bootloader files bl39.bin and bl46.bin). The “unblocking” process is as simple as follows: right click on the file>Properties>Allow.

    Before understanding that iPhone 2G can’t be unlocked with limera1n or newer version from Redsn0w (it can with the version 0.9.4), I’ve been also been stuck on those frozen “waiting for reboot” or “DFU mode” windows for a couple of days! :/

    thank you so much for this. my 2g iphone freeze & died. i decided to go ahead and update after i restore. i did everything you said and did ok up until i got to the.. “waiting to reboot” screen. i cancel and started it again more than a dozen times to no avail. i keep researching & tried unplugging the usb but that didn’t work. i finally decided to restart my mac and unplug the internet then start the redsnow again and it worked perfectly after just one try! thanks again sir! i got my iphone back πŸ™‚ i’m stingy & don’t want to upgrade, i still love my 2g!

    I followed the instructions and it has unlocked perfectly fine..

    the only issue im facing is if i open Youtube it says cant open…

    Also i read above that we need to make some changes in Cydia to make youtube work… so i went to Cydia.. and that also has some problems.
    It is giving some error messages… pls find the errors below and let me knw wat i can do to resolve this..

    1st error:

    Error: Clean Archives
    Lists Direcftory /var/lib/apt/lists/partial is missing

    If i select ok and go to next step it gives me option to select who am i..
    so if i select the first option

    Error: Database

    Could not open lock file /var/lib/dpkg/lock – open( 2 No such file or directory)

    and no matter which options i go after that it says cannot locate package…

    I managed to get my iphone unlocked with the help of procedure given on this link. After step 3, it asked for 3.9 & 4.6 bootloader files which I had initially downloaded. I browsed and pointed to the correct location of these files on my computer. I did not had to do step 4 (as my iphone was in recovery mode).

    Now my iphone is working. But it still is not connecting to my wifi? Any help would be appreciated.

    I recently updated my iphone 2g from 3.1.2 to 3.1.3 with iTunes and now my phone is not getting unlocked.

    It comes in recovery mode, iTune detects it in recovery mode, but when I try to restore the sn0wbreeze ipsw file, iTunes tries to restore, unlock the phone but then gives (1600 or 1604) errors.

    Can any one help me unlock my iphone?

    Ignore my previous post. I unlocked my phone and without realizing that it is unlocked, I restored to factory settings… three times πŸ™
    Now it is unlocked and working fine.

  37. US August 18, 2010 Reply

    I’m not sure what I might be doing wrong. I tried three times and every time I ended up going to recovery mode but not DFU mode. I have iPhone 2G with 3.1.3 running.
    In step 5, it says “you will be asked to put the iPhone to DFU mode”…. but for me, after downloading and installing few things the phone was just on. Am I missing something?

    I have an apple iphone 2G running which accidentally got upgraded to 3.1.3. It was a jailbroken and unlocked iphone and now it is stuck at the ’emergency’ calls only screen. I am able to make and receive calls but nothing else works. When I connect to itunes it says that the ‘sim is incorrect’. Could someone kindly guide me as to what shall I be doing in this case. I tried the above mentioned steps but redsn0w 0.9.4 says ‘rest of the process takes place on your device’ and my iphone screen goes blue for sometime, reboots and comes back to the previous ’emergency calls’ screen. Please help!!

    jailbreak and unlock

  49. Hubie June 3, 2010 Reply

    My history is like this: I ran 3.1.2, then an update came with Rock! that crashed my phone (I think all files in /sbin was removed), so I restored the phone, to 3.1.3. D*mn. My SIM didn’t work anymore. Then I downgraded to 3.1.2 again. All works fine. iTunes says I am running 3.1.2 again.

    HOWEVER – I have one slight problem πŸ™‚
    My phone can not get a lock on the carrier.
    Anyone knows a fix for this?
    Didn’t 3.1.2 “upgrade” fix the baseband?

    I just got an old (2g) phone running 3.1.2, already jailbroken and unlocked (T-Mobile). It already has about 70 apps, some from the Apple store some from Cydia. If I upgrade using the instuctions above what happens to the apps? Are they deleted? Will iTunes restore the Apple apps? Since iTunes has done a back up will it be able to restore the non-Apple apps? Any help would be appreciated.

    I have a 2G and followed the instuctions to upgrade OS 3.1.3 in redsnow, but I faced the problem is that my phone is in “wait” and could not continue. I tried to restore on older version, but the phone is still same problem, redsnow didn’t continue and wait for something. Can anyone please help? Thanks

  54. Danilynnc May 15, 2010 Reply

    Thanks for your video i spent half the night trying to unlock my 2g on 3.1.3 but when i got to the part where you put it in dfu mode it wouldnt go it kept going into recovery mode. after several hours i decided to call it a night and try again fresh after work. after one of my usual middle of the night trips to the restroom i noticed my iphone was flashing on the desk in the dark so i went to check it out and discovered the power button was sticking and the phone was coming on and turning off in the boot up so the little apple kept going on and off. which is why i couldnt get into dfu mode since it wouldnt power off. it kept turning back on before i could get it in dfu mode. anyway my husband fixed the power button and i sat down at my pc for another try and FIVE minutes later my phone was unlocked! YAY!!!!
    I do have one problem, I cant get MMS to work any suggestions?

    Followed the instructions did not work for me. After a few hours of trying to sort out the wifes old iphone edge I finally got it to work.

    If you have followed the instructions above then you will have all the ispw files down including the basebands.

    Basically go DFU mode on iphone, itunes will require u to restore. Keep shift down and press the retore button. Select the 3.1.2 firmware and it should complete.

    Once complete retored your iphone edge download Blackra1n.exe.

    Run Blackra1n.exe and follow the instructions. Ensure that iphone is turned on for Blackra1n to work.

    Everything is automated. In minutes my iphone edge was unlocked and jailbroken. If you do not see Cydia or Rock dun worry. Click on the blackra1n application and you can install it from inside.

    Did i mention wireless works fine.

    Hope this helps anyone having problems with unlocking and jailbraking iphone edge. Good luck… and enjoy!
