    Question [1.1.3 OTB] Hard way downgrading!

    Dear All,

    I'm thinking in buying a iPhone, and seems like the new version of Baseband does not permit do us unlock.

    My question is, If I remove the Basebend Flash and errase the Baseband firmware, can I reprogram the firmware via ienew?

    Or let's put this other way, what do I have to errase/reprogram in the flash so I can use the available TP/software to unlock the new versions of iPhone!

    I don't want to hear answers like, oh this is very hard to do and bla bla, I have equipment for doing all this in 20 minutes. UV rework station, BGA adapters for reprogramming Flash, etc etc...

    Regards,
    Skippy

    You will destroy 500$ if you try to remove the flash to flash it...

    But if you have the skillz / equipement ask TA_Mobile or GeoHot__ They have done it in the past...

    hi,

    the new iphones are shipped with the 1.1.3 fw. right now it is impossible to erase the baseband because you need the secpack from the 1.1.4 firmware.
    we also had to wait for the 1.1.3 secpack to erase the baseband which is coming with the 1.1.2 firmware.

    this is possible only if the new FW 1.1.4 has a baseband update. if not you have to wait for the next FW which has a baseband update to extract the secpack.

    Hi,

    You didn't understand my question. I'm not asking for a software or TP sollution, I'm asking what should I errase/reprogram directly in the phone's flash to unlock the phone.

    I've been reading that if I errase the baseband firmware, and downgade to BL3.9, I'm able to unlock.

    Does anybody know the offsets to errase from the Flash?
    Is I read form other iPhone 1.1.2 baseband and reprogram my 1.1.3 OTB will it work?

    Regards,

    Skippy,

    This has to be possible because TA_Mobile does it and showed us all that he could.

    I'm just not sure - don't take no for an answer.

    Hi,

    As far as I understood from the hundreds of posts regarding this issue, It isn't possible to downgrade the baseband without knowing the SEC pack from a newer version, i.e. having version 1.1.4.

    But if you have a 1.1.3 firmware that was prevously a OTB 1.1.2 with older baseband, It's possible to unlock because you have SEC pack from newest baseband.

    So the problem here is the baseband, and If i can downgrade or errase the baseband directly with a programmer, the baseband is no problem anymore.

    If there is anyone that has knowledge of the iPhone firmware and baseband that could confirm me this. If this is true, the only thing that I need to do is remove and reprogram flash with older baseband.

    Other question, I assume the iPhone firmware is on another flash chip, and the bootloader is in the same flash chip as the main firmware, if that's the case, I can downgrade the bootloader via TP and reprogram Baseband with programmer, and convert my 1.1.3 OTB in a 1.1.2 OTB with bootloader 3.9?

    If the flash chip is the same, I can make it all at once.

    This procedure was usual in some sonyericsson phones when they lost bootloader in unlocking via bad TP, the sollution was remove flash from board and reprogram only bootloader, and then flash phone via USB or with some flashing tool.

    Skippy

    as i know the iphone has two cpu's. one is with the main system where the firmware (1.0.1/1.0.2/1.1.1/1.1.2/1.1.3) runs. the other cpu is with the baseband and a bootloader. this baseband is responsible for the gsm, bluetooth, wifi, sound, imei, iccid... that is why many ppl have no baseband but the main system is running.
    some firmware updates have baseband update too. from 1.1.2 Fw with baseband 04.02.13_G to 1.1.3 with new baseband 04.03.13_G. this baseband update is the one and only reason why we are able to make the HW unlock!

    if you have new bootloader 4.6 which has no exploits you will always need the secpack from a newer baseband to erase the current baseband. if you have the old bootloader it doesen't matter. then you can up and downgrade to whatever baseband you want.

    here is a pdf from geohot. perhaps it helps a little bit www.tayloredge.com/museum/museum/IPhone.pdf

    thats from my understanding. correct me if iam wrong.

    Hi,

    I thing that you aren't correct, because the 1.1.2 OTB with bootloader 4.6 is unlockable via TP as you can see in Software unlock section.

    What i've read was that you need a newest SEC pack for beeing able to FULL errase baseband, not bootloader.

    Is there any memory map of the baseband flash, like where is located Wi-Fi firmware, baseband firmware, IMEI...etc etc?

    this is more hardware unlock than software
