I'm not sure, but I think I broke my phone when I tried to update to 2.2. I would greatly appreciate any help, and at this point I would be happy to go back to the stock OS.
At first I followed the instructions to upgrade from AT&T 1.6 (build 6601) to OS 1.6 (build 4399) and from there to OS 2.1 (build 8105).
2.1 worked perfectly and I wanted to update to 2.2 so I installed koush's clockworkMod recovery and attempted to apply update-release-1.1.1.zip. For some reason I wasn't able to get it to boot into 2.2 so I decided to roll back to OS 2.1 so I would have a working phone.
So I installed the recovery.stock.new.img recovery image and copied the OS 2.1 (build 8105) to my phone and named it Update.pkg. I did the upgrade and everything seemed fine. It booted to 2.1 and started the installer and automatically rebooted. After that, however, it just froze at the dell logo indefinitely. I left it on for half an hour and the OS never came up.
I tried to access fastboot mode as usual by holding the camera button and then holding the power button but that didn't work. I read somewhere that in 2.1 you need to press and hold the camera button right after the lights come on, but that didn't work either.
I also wasn't able to enter recovery mode by holding the volume buttons and the power button. I also tried pressing and holding them as it booted up, but that didn't work either.
At this point I can't get past the dell logo and I'm afraid that I might have somehow broken my streak. Can anyone help me? Is my poor cell phone beyond all hope?
Any help would be greatly appreciated.
