Thread: No Wi-Fi, No IMEI, No Bluetooth on 4.02.13_G

    Default No Wi-Fi, No IMEI, No Bluetooth on 4.02.13_G
    Hello All, greetings from the Cayman Islands in the Caribbean.
    I have in my possession a client's non-working Iphone with bootloder 3.9_M3S2, with firmware version 1.1.1 which was unlocked and working until it all of a sudden stopped.

    I attempted to fix the iphone for the client.

    Here is what I did:
    1. I tried downgrading to version 1.02. Got error 1604.
    2. Tried going back to 1.1.1. Got error 1604.
    3. Tried upgrading to 1.1.2. Got restore error.
    4. Itunes 7.4 used in scenarios 1 to 3
    5. Used Itunes 7.5 and the phone successfully upgraded to version 1.1.2 including baseband
    6. Downgraded to 1.1.1 but no Wi-FI to activate from Also no Wi-Fi to use the unlocking tool to downgrade to 1.02 baseband.
    7. Downgraded to 1.02 in DFU mode and activated using Independence.
    8. Used Ibrikr to install mobile terminal on springboard as well as BSD subsystem.
    9. Uploaded secpack, ieraser, *.eep, *.fls etc to usr/bin using Ibrickr Changed permissions to run. Also uploaded virginizer_pack to usr/bin
    10. Used mobile terminal to run ieraser to flash baseband which run without any errors.
    11. I run bbupdater -v after procedure to ascertain success but realised that baseband remained at 04.02.13_g

    In hindsight, I should have attempted to restore Iphone to version 1.1.1 using Itunes 7.5 and maybe I would not have been in that problem.

    At this juncture, it does not seem Ieraser can flash a 04.02.13 baseband and as a consequence, in virginizer_pack will not run successfully to repair the apparent damaged baseband. My only success in downgrading the 04.02.13 baseband in another scenario is using the source, unlocking tools which downgrades right down to 1.02 baseband version.

    Does anyone have suggestions on how I can get out of this? I have great confidence that the phone can be salvaged, if I get it to a point where I can successfully run

    Thanks all.
