How to upgrade an xv6800 with the new Sprint ROM
 

Here are the steps I have successfully used many times to upgrade my xv6800 to the new radio and a custom ROM.

1) For good measure, perform a hard reset by holding down the 2 softkeys while pressing the reset button then press R
2) Just in case record your MSID, MDN, and if you can see it A Key from the PST. You can get there by dialing ##778 Send and using 000000 as your code (I've never been able to see my A Key)
3) Install Olipro 2.4 bootloader (during installation of the bootloader, after disconnecting and reconnecting the cable from your phone, the RUU instructs you to make sure you have an ActiveSync connection. Ignore this, it is not necessary.)
*When complete be sure to disable USB in ActiveSync to get out of the bootloader (File -> Connection Settings -> Uncheck "Allow USB connections") Re-enable this before the next step
4) Install the new Sprint ROM
*DO NOT LET THE SPRINT CUSTOMIZATIONS RUN!!! When the flash is complete and you arrive at the Welcome screen it will ask you to tap the screen to proceed, DO NOT PROCEED ANY FURTHER. If using DCDs kitchen you can proceed to flash from here. I can't speak for others although I believe they will do the same.
5) Finally, install the custom ROM of your choice. I am successfully using DCDs 3.0.1 without any issues.

Things to note:
1) I never let the Sprint ROM boot up and run the customizations
2) I had the slow signal aquisition issue so ran *22802 then hit End as soon as it connected
3) I also re-entered the MSID and MDN
4) After performing steps 2-3 I no longer have the slow signal issue
5) No A key was necessary
6) I never had to run *228 to OTA program (in the past programming with *228 has reversed the effect of re-entering the MSID and MDN)

The theory is that the Stock Sprint updater copies your PST settings out before the install then restores them post-install. This is why I never needed to dial *228 or re-enter my A Key

GPS is running great
Not sure about Rev A, still need to tether and test

First of all I would like to say thank you from all of us XV6800 guys

Just have a couple of questions...
"*When complete be sure to disable USB in ActiveSync do get out of the bootloader"
Did you mean to get out of the bootloader?
Im guessing this a easily accessible setting in activesync? (Im at work)
Also when you stated...
"*DO NOT LET THE SPRINT CUSTOMIZATIONS RUN!!! When the flash is complete and you arrive at the Welcome screen, DO NOT PROCEED ANY FURTHER."
How do I stop it at that point?

Those are about the only questions I have. This post is great. I am very excited now to give this a shot.
Thanks so much Geckotek

What do I do if Im not tapping the screen? it says, "DO NOT PROCEED ANY FURTHER." Does that mean I get out of it somehow?
Thanks a lot, you are awsome!

It means soft reset before the customizations run. I think you have to wait until the WELCOME wizard has completed, but I am not sure.

To be safe: When the screen says "Your device will customize in 3...2..." then RESET (soft reset, pinhole method) before the countdown ends

/\ Correct

Actually, you can just leave it on the welcome screen or manually put it into bootloader and move forward with flashing the ROM of your choice.

When it's on the welcome screen, it is connected via AS. I can't speak for other custom ROMs, but DCDs kitchen will take it from there an boot it up to the bootloader.

Okay, so I'll manually put it into boot loader. I would like to then load DCDs 3.0.1. Do I have to use a RUU or is this an exe and will boot okay on its own?
Thanks,
