I'll try to give you all the details...
I've got a refurbished Motorola Droid running 2.2.1 with FRG83D
I used Soup Or Root to root the phone a few weeks ago and I had overclocked it to 600-800mhz with no issues.
Recently it's been prompting me to run a system update. I've been hesitant because I wanted to make sure nothing would go wrong if I updated a rooted phone with an OTA update.
Today I took a shower and had the phone in the bathroom with me playing Pandora. I have had the phone in the bathroom while I showered a few times before with no issues.
About an hour later, I pressed the Volume Up button to make sure my ringer was all the way up. Nothing happened. I pressed the Volume Down button thinking I may have been in a screen that did not allow ringer volume changes, but the volume went down. I pressed the Volume Up button again, but the volume would not go back up. The Ringer Volume screen would not appear on the phone when I pressed the Volume Up button.
Not sure what was happening, but thinking the phone may be confused or bogged down as it does sometimes, I held the power button and turned the phone off.
I pressed the power button again to turn the phone back on, and the phone went to the Bootloader 2c.7c screen.
I killed the power again, took the battery out, and tried blowing any lint or dust away that might have collected in the battery compartment. I then took the Micro SD card out thinking it may be interferring.
Replacing the battery and turning the phone back on, I get the bootloader screen again.
I have taken the battery completely out and the phone is currently sitting in a bowl of rice (screen down, battery cover on, rice on top) to try to pull out any moisture that might be causing problems.
I can't remember what exactly needs to be pressed to go into the bootloader.
I had also found this thread with a similar problem:
I assume that if the phone has experienced any permanent damage to the circuits that it would be doing something completely unpredictable, so I'm hoping this is a temporary problem. We will see.
I also attempted to take the phone apart by taking two exposed screws out of the back that are normally hidden under the battery cover. With these two screws removed nothing came loose so I didn't want to go any further and risk voiding any warranty I may have left.
This is a replacement phone for a previous Motorola Droid.
