I performed this on my Alltel Touch and was able to get it replaced with no problems.



DOWNGRADING AND REVERTING BACK TO ORIGINAL SPL
This has been proven to work for Sprint(not sure about others). This will NOT completely remove the 3.xx radio from your device. It has been said that the 3.xx radio will remain on your device in a dormant, non-usable state at a much lower level on the device and can potentially cause problems later on. DOWNGRADE AT YOUR OWN RISK!!
1. Download ImCoKeMaN's original unlocker here: ftp://ppcgeeks.com/Vogue/Users/dharv...e_unlocker.exe
2. Run Vogue_unlocker.exe and follow the on screen instructions to a T as it is very easy to mess up. This will overwrite the 2.31.coke SPL. During the unlocking process your device will display 0.36.coke SPL. This will change once update is complete.
3. Once you finished with the unlocker, your SPL should no longer display 2.31.coke but should now display 0.40.coke.
4. Your device will automatically soft-reset after the update is complete. Do not allow to boot back up into OS. Instead, hold down the camera and power buttons and insert the stylus into the soft-reset hole again putting you in bootloader mode.
IF YOUR DEVICE DISPLAYS AN SPL OF 0.40.coke THEN CONTINUE TO STEP 5. IF NOT THEN RE-RUN STEPS 2&3 UNTIL IT DOES.
5. Since it is recommended that you flash back to the OEM 6.0 Sprint ROM at this time, that is the link that I am providing here. Download and flash the OEM 6.0 Sprint ROM. This will overwrite the custom SPL written by ImCoKeMaN's unlocker.
6. You're now done. Your phone has now been reverted back to it's original shipped state.

PLEASE NOTE: It has been said that GPS radios and Non-GPS radios are very different. Flashing from the original 1.13 Radio to a 3xx Radio will write a TOTALLY new Radio to your device and reverting back to the OEM 1.12 Radio will not completely remove the new 3xx radio.
Carefull, I did this with a xv6900 and bricked it, I did use the Vzw rom dump not the sprint one.
