galaxy tablets and problems

[th3joker]

i have a samsung galaxy tab 4 7" that the power button doesnt work. the screen turns on and shows its charging. i kept it in standby mode for months until i finally fell asleep watching youtube and it complety drained the batterie. i said fuck it bought a newer model galaxy tab A 2016 7 inch. well i didnt use it in like 6 months. and now its on a boot loop charge cycle. it wont charge at all it powers up when plugged in tge screen turns on shows the dead battery symbol like it wants to charge then shuts off and then repetes the cycle over and over. i even tried different chargers and cables. let it boot loop all night but still nothing. any help? i remember starting to research a way to boot the tab4 with a pc program debugger via usb BUT the files to the programs were dead links. The tab4 is rooted the tab a is not.

i held the sound button and the home button while inserting the usb. it boots to debug menu that i can then fully boot the system. so i figured it out on a whim. pretty funny. the newer tablets batterie is still fukd tho

i can boot to the dev debug preboot menu on the tabA but just for a sec and then it dies. the bstterie wont accept a new charge left it dead for too long i suppose
