It is correct, this is "binary" from the latest official version of the software..
The software can still be patched by "Magisk" but after that very often there are unexpected restarts after trying "superuser", I think you need to turn off Knox or something similar

TWRP port for Xcover4 has a forced encryption BUG or

Image Kitchen , have a look at the Recovery. FSTAB at \ramdisk\etc


Cheeers.

I think I fixed it ,,, but it should be a peace of cake ,, a childs-play for a Android --Pro to see the misstake and even

make it better,,,,, sure.



Yeahhh,,, well didnt fix it completly,,, Data remains unmountable,, BUT ----- the mobile runs so smoooooooooooooothhhhhhhhy ..

And no more WTF Bootloader not unlocked anymore and ,,, I managed to mod the vanilla OS Pie Patch Version 5 , really small and flashable in 2 Steps , in case the bootloader unlocks again ,,,

Sure That TWRP needs a look at it... Its useless as it is for download here,,,,,

Sabotage TWRP ; (

Hello, I will maybe throw a block in the pond, although the rom for android 10 or 11 are not available, what would prevent us (user of this phone) based on the open-source code of this tel from going under the version 10 or 11?

Although the information is available for the bonds needed for android 10 or 11, the literature is so long that I would like to find something simpler.

and why not try it in a virtual environment.

Actually, I take back what I said earlier! Those were not the most clear instructions!

Those ZIP packages represent two methods that fundamentally achieve the same purpose. It's not completely clear whether one is more appropriate for Magisk or SuperSU use, the Universal one borrows functions and logic from both Magisk and patches from the no-verity ZIP

This page lays the situation out in detail and mentions the prerequisites for those initially with encryption on or off

    Hi,
    Finally I had time to finish my work on Xcover 4. I couldn't disable ForceEncryption by any flashable tool so I prepared 2 version of firmware (Oreo and Pie), both prerooted (Magisk) and free from Force Encryption. Everything except boot.img left untouched, both ROMs are BTU so no brand.
    Just flash it with Odin 3.13.3. I recommend to flash CSC_BTU instead of HOME_CSC_BTU. HOME BTU should work as well but then probably You gonna have to format data with TWRP. CSC_BTU is already tested and there are no problems with Encryption.
    After flashing just install Lastest Magisk Manager. SafetyNet Passed.


    • Oreo: G390FXXU4BSB3_BTU_G390FBTU4BSC1_Patched_By_Chamelleon

    • PIE: G390FXXU4CSF9_BTU_G390FBTU4CSFA_Patched_by_Chamelleon
    Code:
    https://mega.nz/#!XBhnRCCY!_IOOtXcLsGZQfVY17JD4YxxzaAWJqy2NoxVSrsJRs5M

    If You need TWRP (not necessary to flash this ROMs) flash this version:

    • TWRP: TWRP-3.1.1_SM-G390F_by_nemo-nemo
    Code:
    https://mega.nz/#!DIo1SSBT!w4dPPAF3BEcfQmsy7mANO33Lb5Gj4jzDkrrPfbH56uo
    Working on both versions, Oreo and Pie. I didn't test backup and recovery options but flashing is working on both. ADB and MTP are not working.

    • To remove Security Log Agent notifications use SecurityLogAgent Disable. It will disable this annoying app completely.

    Unpack your firmware and upload boot.img to any cloud drive like GDrive, Mega, MediaFire or whatever you have and post link.

    AP file in AP
    CP file in CP
