iPhone 1.1.3 firmware downgrade complete, still unbricks you, SDK docs leaked

iphoneheaders.jpgJust a quick note to all those with bricked iPhones — you can upgrade to 1.1.3, unbrick it, and then downgrade to 1.1.2. This is all pie-in-the-sky stuff right now but it seems to be working for some folks in Vietnam of all places and it’s a hardware hack, so if you’re squeamish around a screwdriver it’s probably not for you. Fear not, though, a software hack will come along soon enough and then we’ll all be happy.

Lightbulb Unlock iPhone 1.1.3 bootloader 4.6 ok !
Hello all !

I can finally confirm about iPhone 1.1.3 unlocked ok at 8:30PM 15/01/2008 by our team and many help from GeoHot from US, Imth from VN, and some experts about iPhone from Hackint0sh forum ! Great thanks to those awesome guys.

This method is hardware method. So have to open phone.

Status now is:
– Unlock the iPhone with firmware 1.1.3 (baseband 4.03.13)
– Downgrade the phone to 1.1.2 then jailbreak it for normally using.
– Phone will work at: firmware 1.1.2 and baseband 4.03.13.

We are still researching on Unlock and keep the firmware 1.1.3 (mean jailbreak 1.1.3) …

Will upload here some proof clip.

Thanks.
