First off, let me thank droidforums for all the help in rooting my Droid 1. Breathing new life into an old phone isn't enough, more like attaching a jetpack to the device!
Unfortunately, the fun only lasted a few days. The decision was made to root since my warranty ends in less than a month. I got the phone in June of 2010. Luckily (or unluckily as it be), my power button does not work anymore. Rather than remapping the keys, I am going to send it in for a new phone.
I unrooted the phone, flashing back to FRG22D, installed stock OTA updates/stock recovery. When I went into the bootloader used RSD lite to flash, I had to rename the .sbf file due to the rsd memory allocation bug. Can verizon see that renamed .sbf file on the phone and make the conclusion that I rooted/unrooted my phone and voiding my warranty?
I also formatted the sdcard and wiped cache/restore defaults from recovery. Am I just being paranoid or is there something else I should be aware of?
Anyone had any problems with unrooted phones being charged back? Thanks again for all your help!
