mmkay... the mtd0 image from the other downgrade thread has the mainversion set to 1.22.605.2. im still downloading the RUU,but it looks like that contains the .79 hboot,wich theoretically should accomplish what we need it to.
first and foremost: check wether you have an amoled or slcd incredible. check settings/about phone/hardware/hardware version. 0003=slcd,0002=amoled
if youre lucky enuff that this phone is an amoled, this shouldnt be a big deal at all,as youll be able to see the screen the entire time. if thats the case,i would just try and run unrevoked on that firmware,no need to even upgrade back to froyo,i dont think.
you will need this RUU:
its important to use that one,as its the lowest we can use without editing the mainversion number in mtd0.
ill work on getting a PB31IMG for it uploaded,if youd rather.
heres what youll do:
1)reroot and downgrade with zergrush. no need to go back to GB,you can do it in froyo. obviously,instead of the froyo RUU,youll use the one above. you can run the .exe file,or wait for me to get a PB31IMG uploaded.
im about to flash it on my slcd inc so i can give you some pointers for blind flashing your way back if you have an slcd
