[Q] Galaxy s4 I9505 XXUDMH9
Hi all, really need your help. 2 weeks ago I bought this device, before never used android. 3 days ago by connecting it to a computer, the Kies software has given the message
"that there is a new version", I agreed, and then device as if replaced, it start to work slowly stucking on some screens, such as phone book or phone itself, it gives a strange message, that he had to stop the work of a program. Then I tried to solve the problem, but everything i did not fixed the issue, I even think that made it worse. I did the following things.
I tried to root device, did it as it was written on some site, after a Odin has finished, I found SuperSu program, but SuperSu wrote that the binary ihe s not installed, checking the Root, no root access. 2 Performed Data factory reset twice did not helped, Performed to flash again the latest official firmware, but also did not helped, the problem not solved, Uninstall SuperSu. no longer know how else to help themselves, need professional help.
Please write me what should i do? how can return the previously firmware, or how to root it correctly and install new Rom.
My device is Galaxy S4 i9505 T-Mobile Germany version.
RoM version: I9505XXUDMH9
