I've installed successfully TWRP recovery, but after installing Magick, in order to root it, I have a bootloop, with this message:

Your device has been unlocked and can’t be trusted. Your device will boot in 5 seconds​

I cannot enter recovery mode any more. Only I can enter in fastboot mode, and issue fastboot commands.

I've tried to restore the recovery partition with the original one:

fastboot flash boot recovery.img

but even though the flashing terminates with success, I cannot access recovery.

I've downloaded the stock ROM for my Armor 8 Pro, but the SPMultiPortDownloadProject doesn't recognize my phone, when I hit the Scan button. It does recognize the scatter file from the stock ROM.

I've tried unsuccessfully other tools like mtpclient, and SP Flash Tool. SP Flash tool

The solutions here don't help, as my phone isn't recognized: https://forum.xda-developers.com/t/armor-7-ulefone-twrp-and-roms.4116603/

The phone uses MediaTek chipset (MT6771 Helio P60 (12 nm)), and I've installed the MediaTek USB VCOM drivers.

Specs of the phone

UPDATE: I'm using Linux and Windows 10 in Virtual Box. I've made accesible the USB device to VirtualBox.

Only when activating fastboot, I can see the device with the lsusb utility in Linux.

When trying to switch on the phone, also there is a 2 or 3 second period of USB port visibility, but this isn't enough.

    The message is just a warning that the bootloader is unlocked. Afterwards it should continue to boot. I am not familiar with that device or MTK devices but modern phone use a secure boot and as you have modified the kernel image (by Magisk) the boot verification fails. Usually you can fix this by disable DM Verity.

  • Thanks @Robert for your explanation. How can I disable DM Verify? What I can do is to use the fastboot tool.

I don't like this solution, but I've sent it to external repair service.
