Galaxy Tab Pro 8.4 (T-320) keeps restarting
I have a big problem with my Galaxy Tab Pro 8.4 (T-320). I bought it a few days ago....after I turn it on it shows me errors of search, media, settings ...etc. has stopped. I repaired these errors with instructions found here on XDA, but there is another problem. My tablet keeps restarting randomly without any error. So I downloaded the latest firmware from sammobile, flashed it, but it dowsnt help. I rooted it, flashed TWRP and a custom ROM, but it keeps restarting. Sometimes after full boot, sometimes when samsung logo appears, but in recovery and download mode it is stable. Can someone help me?
( sorry for my bad english :/ )
