Install TWRP and Root J400f (Galaxy J4)

before start this process backup from your data. all feature about this phone you can see in gsmarena.

1 - Download last version of TWRP from github
2 - enable oem unlock from developer options.
3 - reboot device to Download mode (for download mode you must completely turn off phone and hold Vol Down + Home and connect USB cable)
you can use adb for download mode when phone is on : adb reboot download
4 - flash twrp with odin in windows or heimdall in linux with no reboot option

if you see red line , you want flash older stock ROM, you need to download latest version , because new bootloder not allow to downgrade , if you see in download mode B:2 K:1 S:1, its means is you can flash ROM with bootloader version >= 2 , boot version >= 1 and system version >= 1 i have same problem in A5 2017.
you must download last version of ROM from here. this problem solve if you use new versions.

for other problem your RMM state is prenormal , you must wait 7 day (168 h+) without any reboot or change ROM.
