Upgrading issues on PPC6800

[Iguana775]

Is it even possible to upgrade the USCC version of the PPC6800? I have been trying all day to upgrade it to the 3.35 ROM as described above in the sticky section.

I unlocked it and went to install the Sprint 3.35 rom version following the stops in the guide but every single time I do it, it stops at 11% and I have to go through the recovery process.

I also noticed that there is now no radio version in my device info screen. I just have the ROM version, ROM date, Hardware version and Browser version with something in it.

everything seems to work fine, calls, texting, internet though. I would like to upgrade the ROM but if not, I would rather just go back to the original factory settings. If I do that, how would I do that? does the relocker work for USCC phones or is that Sprint specific?
