please help me to solve it
When entering BOOTLOADER are you able to press volume down and see NORMAL BOOT, POWER OFF, RECOVERY MODE, & RESTART BOOTLOADER? If so have you selected Normal boot instead of recovery mode?
Also try booting in safe mode.
When power is off:
1. Long press power key to boot.
2. When ASUS logo appears, press and hold volume down key till home screen appears
3. “Safe Mode” reminder appears on the lower-left of home screen

I have the exact same symptoms, though I didn't do anything to trigger it - the phone just failed to boot this morning.
Did you get this fixed or is it going to be yet another warranty claim?

Are you using the correct steps to enter recovery mode?
1. Power off your phone
2. Press and hold the volume up button, then press and hold power until the phone vibrates
3. Let go of power ONLY
4. Use volume keys to select recovery mode on the next screen.
5. If you have stock recovery, it will say "Error". While holding power+Vol down, press and release Vol up.

Looks like u messed up during unlocking the bootloader.. Try flashing the stock ROM by QPST method... then again try to unlock the bootloader from the guide available at XDA ... For flashing via QPST... go to this link
https://zukfans.eu/community/threads/indian-z2-plus-qpst-official-firmware-zui_2-0-093_st.587/
and there is a guide too for QPST flashing on XDA ... All the best
view the video in the OP please
that is my actual scenario,
my device is only being detected as a CD/DVD that too after installing Zuk USB drivers.
I am unnable to switch it off if it has any battery left..
it will only switch off at 0% battery..
and the options on screen are not working
EDIT : I got to know i'm stuck in "all auto test mode"
Even telling me the key combinations to reboot into normal or some other mode is appreciated.

Realme 3 Endless Bootloop

My realme 3 was working normally since I got it, but one morning, I woke up to it stuck in a boot loop state- unexpectedly, of course.
I went online to search for solutions, but all of them required me to enter recovery mode/ fast boot mode. When I try to enter recovery mode- by holding down the volume down+power button- it will say, on the lower-left portion of the screen, "recovery mode>". But, it will then start its endless boot loop cycle once again.
I have tried going into fast boot mode- by holding down the volume up+power button- and it just goes into a black screen for a few seconds, then starts its endless boot loop cycle once again. I also cannot turn the phone off by holding down the power button, but by pressing all three of the physical buttons (both volume keys+power button).
What can I do?

My Nubia RedMagic 5G NX659J Keeps booting into edload

When i power on the phone, After showing a message " The Boot Loader is unlocked and software integrity cannot be guarenteed ... Press power Key to Continue"
I see Redmagic logo and then screen turns off (edload). I can go into fastboot mode, recovery mode. I did try flashing official firmware zip from recovery mode, it completes everything but again after restart go into edload.
i tried Miflash method which completes the flash process. Restarts the phone > red magic logo appears and for a brief moment i see WHITE background Redmagic logo with some loading bar and then it restarts and goes into edload mode.
whatever i do the first messege remains constant that boot loader is unlocked and afterthat goes into edload
please suggest what can i do.

boot the phone into fastboot mode
connect the phone into the computer and open cmd or powershell
go to where you have the ADB files and type fastboot flashing lock
reboot phone and the message " The Boot Loader is unlocked and software integrity cannot be guarenteed ... Press power Key to Continue" will not show up again, you might need to use the the [Tool] Nubia Red Magic 5G Unbirck Tool to fix other booting into edload part.
