How to unlock RMM State
Flash latest full stock firmware of your country with Odin, boot up, don`t reboot, don`t unplug the sim and don`t disconnect the network connection for 7 full days (168h). It seems that after 7 days of uptime, RMM state resets and you can flash TWRP again without issues. You can see uptime in settings/about device/status.
But it can’t guarantee it still works.

- Once Odin3 finished to flash the recovery (you should see a “PASS” message), force reboot your phone ( Press and hold Volume Down and Power keys together ) and when the screen is off, press and hold Volume Up and Power keys together to boot TWRP Recovery mode.
- Once TWRP is booted you first need to decrypt your /data partition. To do so touch Wipe>Format Data and follow the instructions in screen.
- Once it finished go back at the home screen and touch Reboot>Recovery. TWRP should be able to mount your data partition.
- Now copy the no-verity-opt-encrypt and RMM Bypass zip you downloaded before and flash them (touch Install and select each zip to flash it)

Notes / Warning!
- Use at your own risk, I’m not responsible for bricking your device.
- Using the incorrect file may brick your device.
- If your target device has a custom firmware flash counter, Rooting will trigger it. If you’re lucky, Triangle Away has support for your device and can be used to reset the counter.
- If you have a KNOX-enabled device, Rooting will trip the KNOX WARRANTY VOID status !
- If your device storage is encrypted, Rooting will wipe your data !
- If you have locked bootloaders, flashing one of these will probably brick your device – with the exception of Nexus devices, which will usually automatically “OEM unlock” and wipe your data !
- Make sure to backup your important data before root it.
