Question Red Warning and UnWorking Lockscreen. HELP

[Stusick]

Hello, dear owners of this beautiful device.
After an unsuccessful attempt to get root, such a warning appeared, plus the ability to lock the screen disappeared. As a result, I didn't get root either and problems arose)
Could you show the instructions how to fix everything step by step and get root? Thanks)

Hey, so I have the same problem as you. I was installing the patched boot.img file when I rebooted, but there was no magsik app. After I tried to flash the same file again, except I put in some vbmeta file because some website said so, now my phone's files are corrupted. I got into fastboot mode and put through recovery mode, and did a data wipe and one final reboot, but even that did work because it said my phone is corrupt. The last thing I will try is to install TWRP, remove the old data, and install the update to restore the previous ROM files. I'll let you know if anything works. Just try ur methods and let me know if they worked. Sure is an expensive paperweight if it doesn't work...

Your boot loader must be unlock
Reboot to recovery, choose English when you see "Wipe data" type
adb reboot sideload
Once your phone boots into sideload mode (When you see the two error line at the bottom of the screen) type
adb sideload NX729J-update.zip
When the transfer is successful ( with a transfer of 2.0 display) you can wipe the data twice with the first and second options and reboot the phone. If you are lucky, the phone will boot

Download global V3.19 rom from: https://rom.download.nubia.com/Europe&Asia/NX729J/V319/NX729J.zip
Download QPST and QFIL flash tool from: https://www.mediafire.com/file/220h5xaxi1gd55m/QPST_2.7.496.zip/file. Install the driver (provided in the download) and these two programs.
You could then flash this rom V3.19 using QFIL flash tool. If you can flash this rom successfully your phone will work.

For QFIL, use Flat Build and in the configuration use ufs. Good luck!

Your version V4.18 will be replaced by V3.19. This V3.19 version can be flashed through edl mode. I could not find V4.18 in this format. The two roms are very similar. They are both global roms.

If QFIL does not work, you need to do side load the rom multiple times again then it might work!

turn off the red rm8 notification (Your device is broken. It is unreliable and may not work)
- enter command on PC: adb reboot "dm-verity enforcing"
- on phone for rooted device with termux: reboot "dm-verity enforcing"

- on phone for rooted device with termux: reboot "dm-verity enforcing"

The command on PC shows "Too many arguments." The Termux one works. Thanks!
