Dangers of downgrading after installing GPS radio (and a little on signing)

[OJM]

[quote=ImCoKeMaN;276445]Ok there is a TON of confusion here, let my try to clear things up.

SPLs:
0.40 will be overwritten by a flash if an nbh includes an SPL
2.31 will not be overwritten by an nbh (only via OS aka unlocker 0.40)

Radios:
1.xx radios/non-GPS work with 0.40 SPL only
3.xx radios/GPS work with 2.31 only

Okay, here goes. I have bricked my phone and I think I can now figure out why. I believe that I may have mistakenly loaded SPL 2.31 BEFORE upgrading my radio to 3.xx. I then flashed the new 3.05 ROM (w/ GPS). My device is now inoperable. It gets stuck at the HTC splash screen when I reboot OR, if I enter bootloader mode (take out battery, put battery back in, hold camera + power) I get the red/green/blue/white stripes and it reads "VOGU100 MFG, SPL-2.31.CoKe, CPLD-3".

I have tried the unbricking process and but every Sprint original signed ROM I download won't work (i.e., I get an RUU Error message telling me that the file is corrupted - this happens with every link I have tried). Any thoughts on how to unbrick? I appreciate all suggestions.

Same exact thing here *****PLEASE HELP!!*****

I don't believe that is correct quote below... You ARE suppose to go to the Coke 2.31 before you do the radio update

OK OJM... I figured out how to fix our problem MAybe this will help others as well.

After an insane amount of reading I figured out that it might work to do a SD card flash of the Alltell RUU 3.37.10

Easy to follow steps in order.

1. Use the 512mb card and make sure it was formatted in FAT32
2. Copy The Alltell files to the SD card
3. Power...Picture...Reset buttons at the same time for bootloader mode.
4. Let the unit load up on its own.
5. Soft reset at the time the Alltell rom want's to decompress the setup files. (you will see a message giving you 3 seconds)

Walla!!! Got it out of the Splash Screen and everything works.. After that I loaded up a Cooked 6.1 ROM that i liked with Rev A and GPS

- Same thing happened to me, but i didn't try to go back to the stock rom... instead i just used the altell rom upgrade... and that got the device to boot, afterwards i noticed my internet didn't work, so i re-flashed it with OMJ's rom and it all worked perfectly... GPS and Rev. A are working fine
