I have a galaxy tab 3.7.0 rootée.
I downloaded and I put it on the external card from my shelf a custom rom. I put my tablet in recovery mode and I made a backup but instead click backup to sdcar1 I chose sdcard0. The backup stopped giving me an error then I immediately reboot the tablet but it hangs logo. I tried turning it off but no way it restarts. I like even put the tablet into recovery mode but the download mode appeared. I flashed the tablet with an official ROM "T210XXAMKE_T210OXXAMK1_XEZ" with Odin307. the flash is done successfully and tablet restarts, update and a tablet is stuck in the logo.
I do not know what to do, help me please. Thank you for reading and responding to my S.O.S
The tablet is still on, no way to turn it off.
