[Samsung Galaxy J5 Questions & Answers] yukinoshita:
well first i want to say hello, i will explain my problem how started i wipe efs from my phone via z3x box because I was trying to fix imei, baseband, and no service sim problems. I have an unknown and i'm failed the idea was stupid and i did a reboot and i faced some problems in frp has locked bootloader i think its text is red i downloaded firmware rom stock from sam mobile and did flash on odi, but I downloaded the last version and binary U2, this is the file name G570FXXS2CSH1_G570FOJV2CSI2_TUN then the phone turned on and entered me on the recovery mode and showed me " installing system update " and then the "Erasing" and then he restarted alone and it appeared after him "No Command" I pressed the volume up button and the button power so that I see what I'm wrong, I tried to find my combination binary u2 and i didn't find only binary u1 and i have frp lock ON so i can't install root or TWRP on my phone and also i could not to boot into the system so I searched on google and found a file named "SM-G570F U2 Android 8.0 FIX DRK - dm-verity Failed Frp ON RMM ON.tar"

I knew that this file would fix my problem is " E:[libfs_mgr] Couldn't create verity device!" I'm flash my phone and put this file in the place of BL and also put the AP file system which I think is 2 GB and when he succeeded in the flash process my phone did a restart and showed me the SAMSUNG logo and entered me to the system, but another problem appeared to me, that the touch does not work, I cannot press anything if I hold on the power button, and i'm see RESTART and SHUTDOWN appears to me, but I cannot even click on them. I thought that this problem is from the file that I flashed to the location of BL, perhaps, also I am unable to enter recovery mode unless I flash 4 files again but my question is there is another solution To fix my phone? I want it to come back :crying:
