Please help! After successful downgrade from 4.4.2 to 4.1.2, my tab 3 refuses to charge while turned off. Stuck at the stage of starting to charge where you have the battery symbol and a circle inside it. Even when cable is removed it won't go unless restarted by long pressing the power button.

It charges well when powered on but not otherwise! Every other thing is working normal.

Could it be that the downgrade has tampered with the charging software.

What can I do please?

How did you downgrage your tab? Using Odin or a Nandroid?

4.4..2 has a locked bootloader, I do not think you can revert now to 4.1.2 without issues because you will have a mis match . Your only option may be to reload 4.4.2

well. you are pretty much stuck then. bootloader controls charging and so, mismatched bootloader and kernel are not a good thing
