My tab 2 GT-P3113 can not boot in to download mode(recovery). If you hold down the power button and either the down volume or the up volume the tablet just boots up normally. The volume buttons work just fine but this screen and area appears to be gone. I have tried hundred of times and nothing. I have done a full restore and no change. I am running 4.1.1 ROM that I have I had for awhile via Kies and no issue till recently. I have another tablet, GT-P5113, and no issues going into download mode.
Some other issues we are having that might point to the corruption area
-red line though charge symbol when tablet not plugged in but is running.
-when tablet is powered down and not plugged it the screen shows the charging symbol
These are all recent behaviours and if we could get into download mode and maybe put 4.2.2 or something else we hope maybe we can get functionality back.
