Turned my Kindle fire off today, and went back a few hours later to turn it back on and it would not do anything, Wont power on, I have charged it for several hours using multiple chargers. Also tried to boot off the fast boot cable. Im assuming im going to have to send it back fore warranty. Whats my worse case Scenario here since it was rooted and had a custom rom installed. any chances of amazon detecting that. If I cant get it to boot back up will they be able to?
