Hi I'm new here and I wanted to post on this because I have a rooted evo and I want to upgrade to GB. I think I got the overall part of upgrading from rooted 2.2 to rooted 2.3 but just to be on the safe side I'm going to post the steps that I understand. I rooted using Unrevoked 3.
I already have a nandroid backup on my sd card and computer through CWM
1) I go to XDA download rooted and odexed 4.22.651.2 (prefer the simpler one).
2) Save that file to the root of my SD Card.
3) Power down then turn phone back (press volume down + power)
4) Go to recovery wipe data in factory reset, wipe cache, wipe dalvik.
5) Then install zip from sd card. Highlight supersonic 4.22, yest to install. (This is where I'm confused) GB should install then and there right?
6) Reboot system and then go through the entire process of starting up phone like if I had just bought it. Right?
I'm trying to find out the most information I can because I've been told that using unrevoked was not a good idea because I can't download different roms.
welcome to the forums!!!!!!!!!!!!!!!!!!
you are dead on with everything you posted. i would also mention that you should use Calkulin's_FORMAT_ALL.zip. it just wipes does the wipe again. just flashed that prior to flashing your rom.
and yes it is definitely not a good idea to unroot. because you will not gain root again until a new exploit is found with the new hboot.
