Although this is not the final build of Froyo for our Evo's im sure a lot of people would like to have this.
This rom is rooted, with busybox (thanks netarchy) and deodexed.
You will need to
wipe all data and cache (including davlik) before flashing to ensure that there are no issues.
You will also need to flash the new radio and wimax update.
1st
reboot into recovery and wipe data/cache/davlik and flash the rom
Evo-Froyo-2.2-Rooted-Stock-3.26.651.3-Deodexed
when u see the home screen reboot into recovery
2nd
flash the radio update and reboot
Radio-2.15.00.07.28
again... when u see the home screen reboot into recovery
3rd
flash the Wimax update and reboot
Wimax26023
and that should do it.
have fun... and hopefully the final update for Froyo will come sooner than later.
