what would i habe to do to sholes to install bb7.5
would i have to remove it completely or just install bb7.5 right off the bat
Download BB7.5, reboot into recovery (turn off phone and then hold x +the power key), and make a nandroid backup of your current sholes ROM.....
Extract the file you downloaded with WinRAR (select Extract File after right clicking), get the file that comes out of the original file that you extracted, place that file in your nandroid folder on your sdcard
Reboot into recovery again, wipe data/factory reset, wipe cache partition, backup/restore, Advance Nandroid Restore, Choose Backup, then choose the one you just put on your sdcard, and select Perform restore..
Reboot and your done!
Depends on which sholes you have. If it's is an older 2.0.1 ROM you can use the update method. If it's a 2.1 ROM that you have to do the nanodroid backup as posted above (and in the 7.5 thread).
You are right to be wary. There is much bullcrap. Be wary of me too, because I may be wrong. Make up your own mind after you evaluate all the evidence and the logic. - Mark Rippetoe
goto settings about phone and check the firmware version that will give you your answer. If it's 2.0.1 than you can use the update method. Otherwise you'll have to use the nandroid backup.
