    Default [Problem] Iphone 8G recognized as a 4G model

    Hi,

    My v1 (8GB) was running fine under 1.1.4 but after upgrading to 2.2 the capacity of the iPhone went down to 3.3GB.

    After 2 days trying to restore, restore with DFU on a Mac, a PC, with Pwnage, QuickPwn... I had no success. Whatever the firmware revision is 2.0, 2.1, 2.2, I don't get my iPhone with more than 3.3GB.

    I know that on a mac you can limit the "available" RAM with an nvram command but I don't find anything like that on the iPhone.

    My question is, how an iPhone 8G "knows" that it has 8G memory and not 4G ? Is there a test and where is it located and when is it performed ? Is there a way to manually set it back to 8G ?

    My assumption is that my iPhone is now recognized as a 4GB model but maybe I'm wrong, if you have any suggestion to get more that 3.3GB on my 8GB iPhone, don't hesitate.

    Thanks

    Just after restore, do you have 8G or 4Gb?

    Just after the restore, I do have a 3.3GB capacity iphone or 2.81GB iphone.

    It depends if my custom firmware has the default partition scheme or not (535MB or 1000MB for Root partition).

    I was thinking that maybe your phone has 8gb backing but a 4gb logic board. But if you are the original owner and bought it as an 8gb, then it's possible that one of the 4gb chips has gone bad.

    I'am 100% sure the logic board is a 8G as I bought it new and 1 week ago there was more than 5Go of video/music inside.

    My iPhone felt on the ground maybe 10 days ago but everything was working fine (memory was still here).

    You may be right and maybe one of the chips has gone bad. But this was not a problem until I upgraded the firmware so maybe the test of the chip is only perfomed during the restore.

    If that's the case, maybe an iPhone Guru could point at the part performing the test and a way to get around it by forcing the result of this test...
