S4 won't boot up, only SAMSUNG logo blinks
I have this problem with my Galaxy S4 i9505 LTE. I was using this rom:
[ROM] Google Edition S4 rom for i9505[17 Dec][deodexed & odexed 4.4.2, 4.3 & 4.2.2] with I9505XXUEMKE_Modem.
I had some issue like random turn offs during call, lately the phone started to turn off more often and today it got worse. When I turned on the phone only the logo appeared, but the download mode worked. So I sad nevermind, I will flash back original ROM, so I flashed via Odin: ETL-I9505XXUEMK8.The flashig process went smoothly with no errors, but after the phone restarted the problem is still present (it didn't boot up).
Any suggestions? I am really desperate. Flashing back the original ROM was for me the solution for everything in every phone I had before.
Download mode still works fine but I am not sure what to flash and I don't want to just try everything. At least for the warranty issues I now have an original ROM inside.
