    You can try 1.0.1. It didn't work for me.

    has anyone figured this out, I have a week 50 phone with the following symptons:

    no-imei, no wifi, etc. I had tried to do the HW unlock and my phone froze after the ienew command. Now im stuck with no baseband, the following is my attempts at restoring in DFU

    1.0.2 - Stuck at Waiting for iphone
    1.1.1 - Unknown error (1011). still no wifi/sound/etc. and a repair needed txt
    1.1.2 - Unknown error (1002). still no wifi/sound/etc. and a repair needed txt

    **occasionally i get the 1604 error but i believe that is when applemobiledevice or one of the other helper services times out connecting to device (just a guess), so a reboot generally fixes that one up.

    All of the above were done in DFU mode and ive tried them in multiple different orders. I have a OTB 1.1.2 from week 50, at the moment i'd just like to get downgraded to 1.0.2 so that i can jailbreak without wifi but i've read mixed opinions on if thats actually possible with a 1.1.2 OTB > week 48. I know I could upgrade it up to 1.1.3 to get it fixed but I need a solution to get it activated (I have ATT but no iphone plan). Thanks in advance for any advice given, zenofex.

    ** "EricJarvies" claims to have found a solution but i have yet to try it, anyone else have any ideas. Ive tried multiple computers and multiple itunes versions but still no luck. At the moment im debating on upgrading to 1.1.3 but will only take that route if i can jailbreak and activate afterwards (not so worried about unlocking)

    I have the same problem in my week 50 iphone after trying the testpoints unlock, and i have tried downgrading to 1.0.2 with several itunes versions without success. I dont know if this helps but i have found that when you are in the iphone main screen (world background) if you turn off your ring, then the numeric keypad works ok, however IMEI, WIFI, sound and everything else still doesnt work, so you canot do anything . Im just hopping somebody comes out with a solution because i dont want to upgrade to 1.1.3

    Sorry for my english!!

    How about this idea if you have a second iPhone.

    I'm stuck with one iPhone (OTB 1.1.2, week 51, FW 1.1.1) because I ran ienew over ssh and not local terminal. After losing the connection I reflashed the phone (error from my side) leaving it in the state everyone is fighting with. Since I'm not able to flash it to 1.0.2 I had the idea involving my second iPhone (OTB 1.1.2, week 51, untouched yet) for repair. May be the following steps could revive my brick.

    1. Reflash good phone with 1.1.1, activate and jailbreak
    2. Prepare the good phone for the hardware unlock up to the point until the phone has to be opened
    3. At this point all data needed for the unlock is on the phone and the phone is accessible
    4. switch the good phone off and open it
    5. Remove the communications board from the good phone and insert that of the bricked one
    6. Boot the good phone with the bricked comm board
    7. Comence with the hw hack resulting in a hacked and good com board. (Will this work?)
    8. Shut down the now hacked phone and swap the comm boards again.
    9. Now the bricked phone should boot as normal.
    10. Dance


    What do you guys think of that? I'm a little bit unsure because I don't know which parts of the software reside on the comm board and which parts reside on the system board.

    Any educated comments are very welcome

    Thanks

    Finally i did.

    Here is the solution:

    1- Find a jailbroken iphone.

    2- Dissamble Commboard from the error giving no WIFI unknown IMEI iphone.

    3- Install BL downgrade files including nor file into a directory on your working iphone. I put nor file into another directory after ienew i copied it into the directory of BL downgrade files.

    4- Install the no wifi unknown imei iphone`s commboard into the working iphone.

    now press top button and turn on the phone.

    wait for a while because it takes some time like a minute to see the jailbroken springboard.

    once you are in :

    -- go to terminal

    launchctl unload com.apple.CommCenter.plist file....

    go into the directory with BL downgrade files.
    chmod 777 *
    run ienew
    copy nor file into the BL files directory
    test point
    run iunew


    now your no wifi unknown IMEI phone is with BL 3.9

    IMPORTANT : IF YOU EVER RESTORED OR UPDATED A BL4.6 IPHONE TO 1.1.3 YOU CANNOT RECOVER YOUR IPHONE EVEN IF RESTORING TO 1.1.3 ENDS UP WITH ERROR 1011

    If you restored 1.1.3 then you should find secpack of 1.1.3 which --according to some folk-- only available with the new firmware upgrade.

    Congratulations and thanks for the info. I'm just disassembling my good second phone here. Which nor file did you use? And where did you get it from?

    Thanks
