How to fix the cannot mount efs issue with your RMM/KG locked SM-M205F Device - Samsung Galaxy M20 Questions & Answers

Anyone can help me to fix the cannot mount efs issue with RMM/KG locked on SM-M205F Device?
Device is stuck at Samsung logo and not boot past logo . I have tried everything but that PRENORMAL RMM is not allowing me to root or flash any non GENUINE Samsung signed firmware (only official binaries are allowed to be flashed)
I also have EFS backup but i am not able to deploy it due to RMM Locked. Is there anyway to fix this issue ? I will be very thankful if someone help me out from this problem.
TIA

Can you flash the official binaries i.e. Stock Rom, recovery,etc?

Reset to stock

Hi guys. I have few questions for you and would be happy and very grateful if you could answer and help me. First of all i have huawei P10 lite which i have bootloader unlocked it, installed twrp and also rooted. I also made backup of the stock rom with twrp. Now i want to restore my phone as new, i mean i want to get back to the stock rom which i made it with recovering but now how can i delete twrp and then lock bootloader? I saw that i have to use img file to delete twrp recovery - The model number is WAS-LX1 and the build number is WAS-LX1C432B124. I wasn't able to find this firmware and i am stuck now. Can i use other firmware for the model number WAS-LX1 or i will brick my phone? How to resolve this issue? I want to get back to stock.. Please help me..
Also is there any way to turn off the warning that says that the bootloader is unlocked and the device can not be trusted or just hide it? I tried to flash logo.bin file but it didn't work for me.
Thanks a lot guys.
Install recovery image from another firmware for WAS-LX1C432.
You can relock bootloader via fastboot using your code and the proper comand. This would get rid-off warning screen. All the info of firmware and oem info must coincide. Otherwise system won't boot unless you unlock the bootloader again.

DRK & FRP Issue. All help is welcomed and needed.

So my coworker has a Galaxy S6.
This phone was running nougat. She rooted the phone herself to be able to use 'Snapchat'. The other day she did a factory reset which softbricked her phone so she took it to a store where they installed 6.0.1 and the phone was supposedly rooted although supersu said that the binary was not present. Her phone was acting up so i told her to do a wipe cache. after the restart the device said Custom Binary blocked by FRP
then i flashed Nougat (last version). The device presented the bluescreen that said: Device does not have DRK, contact to SW PL please flash ENG binary then install DRK rebooted into recovery and then in the recovery, every time it boots into recovery it says: No Support SINGLE SKU. Supported API: 3. Dm-verity error.... Failed code: 0x02
I tried flashing TWRP but it was blocked by FRP returning the error in download mode: Custom Binary (recovery) blocked by FRP
I cant enable OEM Unlock because the phone wont pass the Samsung Galaxy S6 logo.
What can i do? What options do i have?
************update 1
I downloaded the CF Auto root from Firmware.Mobi: Problem is: The phone is not OEM Unlocked and i don't have access to the phone settings so i can't flash CF auto root because i can't flash a recovery.
************update 2
I can't downgrade either to 6.0.1 (QC2) . So i'm stucked on Nougat, when i try to downgrade it says: (Device 6 Binary 5). Can't root it, can't flash a recovery.
Is there any way to turn off FRP from the recovery using ADB ? Is there anything i can flash in spite of the phone running Nougat so that i can turn off FRP ?
Should i go to a store and ask for DRK to be fixed with a Z3X box ?
