[EVO 4G Android Development] lkszh:
I once rooted my phone with this auto root. It went to manual method, and everything went well. (Thank you very much!!! <3 )

Then I flashed my EVO with a gingerbread from Deck:

[6-13-11][ROM] gingerbread-evo-deck [1.0][2.3.3 Stable][1.2y][2.3.4 Beta]

Then sometime later, I wanted to go back to Froyo, so I did this (WHICH MAY BE STUPID, I DON'T KNOW...): I renamed 3.70.651.1_PC36IMG.zip and put it to SD card and flashed my phone. Now problems!

I don't have root anymore. So I tried to use the auto root agaon.

When I got to step 7:

If you are entering the Recovery your phone will show a Red Triangle with an Exclamation mark inside, at this point the script will take back over and attempt to flash Unrevoked Forever.

There was a red triangle with an exclamation mark, but the script didn't take back. everything just stopped there forever. Then I had to restore the phone flashing 3.70.651.1_PC36IMG.zip, then tried again, and it stopped at the same point. And I repeated lots of times. It always stopped there.

By the way, now after restoring my phone, the parameters are:

Android version: 2.2
