my tab sprayed with water and it was working normally but suddenly i powered off , and when i tried to open it it hangs on " Galaxy Tab 7.7 ".
I tried to login to recovery mode but it open in few seconds of recovery mode in few seconds then restart.
i tried the download mode and it works , i downloaded firmware 4.1.2 with only one file and uploaded it successfully through Odin .
But with the same issue , open and hangs on welcome " Galaxt Tab 7.7" , also when i tired to power off it , it restart again and stop in the same message till its battery become empty .
Any suggestions please ?
