I bricked my phone with firmware 1.1.1 and I saw that my IMEI changed to the lockdown code 00499 etc.

Well I did some testing and Found that WinstallerGUI was able to restore the IMEI from my iphone but it was not able to save it to the eeprom of the phone.

Apple somehow managed to skip the original IMEI by patching the firmware at somepoint that identify where the phone was patched by the unlock. It means the code is bypassing the IMEI verification and making the phone to think that the IMEI is 00499 etc.

Also i found that the phone is not bricked at all. The phone was just placed to a type of sleep mode. Also known as the default settings. It means the iphone was put the way it was before all the firmware was loaded. It could be that the eeprom was completely wipedout or formatted.

I think also that tis could be done by Apple rearranging the files in the firmware.

Now if I were able to modify WinstallerGUI to restore that IMEI back to the EEProm my phone will be working again since the phone IMEI still in the phone memory somewhere.

my iphone was bricked also and the imei is corrected when i restore but goes back to 0000499.... when i install the sim card

interesting but makes sense since the IMEI shows up again on a fresh restore and we know it can't be in the ipsw.

the original imei might e store in the basebands folder if you backed up your iphone in tiunes, its there anyway to make that stick into the iphone so it doesn't change
