Question:
I tried to upgrade to the 2.2 operating system using a guide on android forums.
I originally had a rooted 2.1 OS, I don’t know if I unplugged it before the process was complete or if I had to return to a stock OS prior to upgrading; however now I cannot get to download mode to use Odin again.
I have read through some threads and I have a different case, I am not stuck at the Vibrant screen, I get past it. Upon boot up I get the Galaxy S screen followed by an Android System Recovery <3e> screen with some other texts. If I hold the power button, I will get the "Power Reset or Unknown Upload Mode" screen. If I continue to hold the power button, the phone will cycle between those three modes, the Galaxy S screen, the Android System Recovery screen, and the unknown upload mode screen.
I have and am still trying different key combinations to get back to recovery mode in attempts to reload the stock OS and then continue with the 2.2 upgrade.
I have made a video that I will post when I get home later today; any help will be appreciated.
