You can find any tools and instructions in the stickies in this forum.
Thanks for the awesome step-by-step framework for rooting the droid x2. I'm a rooting noob, so I read as much stuff as I could before attempting this, and I've just finished successfully in under an hours worth of work.
Happy 4th of July!
I, however, got stuck at the same spot as the poster above: I couldn't figure out how to manually install an OTA update from an SD card. So, if someone could provide a handy step-by-step guide for this, as I was not able to find the answer anywhere else, that would be awesome!
I got around not being able to do it like this:
After I SBF'ed to 2.3.4 and rooted (used Pete's tool and verified root with Root Checker, then installed Voodoo OTA rootkeeper and did those steps to protect root), I was getting a roaming delta-symbol and I did not have the option to select the update from the "About Phone" area on the phone settings.
I finally used the *228 option 2 method, which apparently re-auth'ed my phone with Verizon, fixed the roaming issue, and also made the 2.3.4 to 2.3.5 OTA available for update automagically.
OTA installed, root access restored with Voodoo, and confirmed again with Root Checker.
And now to freeze/uninstall some bloatware.
Thanks again, however, for the handy steps on making this possible.
