Re: Uscc 6800 Gps, Custom Roms, Downgrading Guide
Thanks for the heads up. I just checked my boot version (SPL-1.07.0000). I will use SPL 2.47 to unlock my phone and do a reset again to check boot version. am asuming it will now be SPL-2.47. After I unlock my phone I will first need to update my radio firmware. I have radio 3.42.40 - inside this folder is a file TITAIMG.nbh. I will replace the one in SPL 2.47 with this new TITAIMG.nbh for radio 3.42.40 and run SPL 2.47 again to update radio. I hope this is correct. can you explain how to do this from bootloader screen or how it is done in basic steps so I know what to expect. OK Continue with what I think.. After I update the radio to 3.42.40 I will need to update the ROM. First to ROM version 3.1.2. This rom is in a .exe format so I will need to connect the phone to computer via usb and run the 3.1.2.exe ROM. I dont think I can use SPL to do it from bootloader screen? correct? If this is correct. Like BillThyCat said once I load 3.1.2 then load back my MSL/SPC setting via qpst. Once this is done I can run the latest ROM which I have to be 3.3.4.exe. Again the ROM is a .exe so I will not be able to do it from a bootloader screen correct?
Thanks alot for your help. any way I can call you or chat with you when I do the upgrade? I just dont want to brick my phone.
