[Q] Galaxy s4 does not work, the system shutdowns, will not play audio
Sorry guys but I have an urgent problem , a friend of mine gave me his galaxy s4 to "fix" , in fact the phone , gave continuous " process system is not responding" , did not play either audio nor video files, the application camera crashed , all Buyer's slow to open up and hangs around the phone , even the screen locker of the time when I drag your finger over it takes a while to unlock. Above all, the worst thing is that the audio in both capsule and a speaker system is not heard. If perhaps they call on the phone can not answer you the black screen and before leaving the screen with the green ring to answer spend quite a lot of minutes. Practically can only be used for surfing the internet , facebook etc. . The firmware is the MHB . I went to download mode and saw that the counter is 0x1 KNOX , of this I realized , however, only when I installed the firmware MGG vodafone via odin because I thought it might be a problem of the system that was in forced shutdown but not so unfortunately. Now even though I know I will load the MHB reinstall it again . He reported the problem three times to the store where she bought it but have always said that the phone was fine, but trust me it is not at all like that . To my friend, I asked him if maybe he did root on the phone earlier but I said no , also because it is denied , he still does not know is because it came out that 0x1 next to the counter KNOX , some will have been his friend but did not even know . You have an idea about it? that problem can be and above all ? If it is a hardware problem I'll have to send for repair or strength I can fix by just replacing the piece in question ? But the most important question is: " If you were to send him to pay support ? When how much? "
Sorry for my english, but I do not know the language so I used google translator
