Thread: Error 1 when trying to downgr 1.1.3->1.1.1

  1. #1
    Default Error 1 when trying to downgr 1.1.3->1.1.1
    EDIT 25 JAN 2008!!:

    The problem is solved rather easy: scroll to post #11 & #12 of this thread!!

    And since i could not reproduce my own foolish method again, please ignore it!!

    Hello. i putted this as an answer in another thread, but maybe there are more people who experienced this issue, so i might help more people with this thread..

    I'm on Mac-OS but it'll probably also work on Win (however, looks like error1 apears on Macs only, not sure)

    This is what i did: i putted phone in dfu-mode (i always had trouble with the 'release pwer-button' thingy, so I always put the phone in the dock and keep pressing both buttons untill it jumps in recovery; always works for me)

    Take your 1.1.1 FW-restore file, duplicate it and put one in you/library/itunes/iphone Software Updates If there is already a iPhone1,1_1.1.3_4A93_Restore.ipsw file in that location, trash it.

    open itunes, click ok for version-check and click ok for 'found ph in recov-mode' Now click 'Restore' (not alt- or shift) and itunes should now start d/l'ng the firmware. WHILE itunes is d/ling go to your /library/itunes/iphone Software updates and now trash the file wich itunes is d/ling (iPhone1, or whatever) and rename your 1.1.1-restore to 'iPhone1,1_1.1.3_4A93_Restore.ipsw'

    Now itunes restores the iPhone1,1_1.1.3_4A93_Restore.ipsw file, wich is actually the 1.1.1.
    When done and you connect the phone to itunes or independence they both will tell you the phone is on 1.1.3, however, now i was able to put it in restore again and downgrade to 1.1.1 in itunes without error1: take note: this time you'll have to use the alt-restore to locate the original 1.1.1 FW (not the renamed one)

    After this i had to do another restore to 1.1.1 , (putting phone in restore-mode, alt-restore to orig 1.1.1FW-file again)
    Now independence kicked iphone out of recovery and i could jailbraek as normal (i use the *#307# method)

    Than run baseband downgrader and after that you can unlock with anySIM 1.2.1u

    I really hopes this works for you and these are all of the needed steps, because i slapped my phone for one day with any kind of possible trick/up&downs..

    Let me know if it works for anyone else pls..

    When doing this, I get error -50 after the first restore.

  3. #3
    I can't remember if/what error i got, but did you try a second restore? (with org 1.1.1 FW) The second restore will probably give an error 1015 but thats ok; just kick it out restore with independence.

    Oh, and did you get the error after restore or after 'extracting firmware'? When it completed the restore, you can just ignore the errors..

    Restore it with 1.1.3 first, then restore to 1.1.1 and then restore to 1.1.1 again. That should work.

    Maybe it should work, but it certainly did not work for me.. I also tried a restore to 1.1.3 (more than once), but as long i was on 1.1.3 i could impossible restore to a lower FW; just got error 1 before the actual restore would begin..
    I unlocked and upgraded more than 20 iphones, so i'm not completely unexperienced with this.

    Btw; instead of changing the downloading FW it may also be possible to rename a 1.1.1 FW-file to 1.1.3 and -alt restore it..

    I don't get how you're deleting the 1.1.3 download file while it's downloading, it won't let me empty the trash while its downloading. Do you mean delete it once the download is complete? I am having no luck with anything right now, everything except restoring to plain old 1.1.3 is resulting in error 1 for me. This sucks.

    When i tell it to restore, it automatically starts downloading a 1.1.3 firmware even though I have the fake 1.1.3 in the right location and when the download completes it immediately uses that.

    I had the error 1 problem last night because I was holding both power and home untill I saw the plug symbol, wrong! Keep the phone docked, press power+ home untill power is off, let go of power but keep holding home untill your computer says iPhone in recover mode.

    Default Solved for me now!
    Put the iPod touch in DFU (restore) Mode as follows:
    You have to start with your 1.1.3 in activation mode (emergency-call screen)

    Press and hold-down both the Power and Home buttons.
    Release the Power button when you see the phone disconnects and disappears from iTunes. This takes place in about 10 seconds. The iPones screen is black.
    Release the Home button when you see the iPod re-connects and re-appears in iTunes. Again this happens in about 10 seconds.
    The screen should still be black!! now navigate to your 1.1.1 FW (.zip) and the restore process should go fine..
    After restore you get error; ignore it. Now do a 111 restore again and after that (same error 1015)
    Close itunes & open independence to activate it..

    At last...

    Thanks to all contributers!!!

    I'll edit my older posts, because that didnt work for a 2nd time..

    Just so everyone is clear on this thread.......

    Are you guys restoring to 1.1.3 straight from itunes or are you guys using the edited one (shift click)?
