Follow the instruction on the following page:
"You can try to use the instructions given on this page https://forum.xda-developers.com/red...t3940057/page2. Extract all img and bin files from the Global ROM and place them into the folder where the "cmd-here.exe" is. Also you need "system.img" you can download that here https://drive.google.com/drive/folde...pQ1KK1LjysSfYm, but dont download the other files they might be the Chinese files.
After you extracted the img and bin files and placed them into the folder where the cmd is placed connect your phone to the computer, open the cmd exe and run the commands
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash parameter parameter.img
fastboot reboot bootloader
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash splash splash.img
fastboot flash modem NON-HLOS.bin
fastboot flash system system.img
fastboot flash dsp dspso.bin
fastboot oem nubia_lock NUBIA_NX629J
fastboot reboot
After all that you should be able to go into recovery mode through fastboot mode if not then try and flash dtbo.img and vbmeta.img in the line of commands so for example "fastboot flash dtbo dtbo.img" and "fastboot flash vbmeta vbmeta.img" looking something like this...
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash parameter parameter.img
fastboot reboot bootloader
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash splash splash.img
fastboot flash dtbo dtbo.img
fastboot flash vbmeta vbmeta.img
fastboot flash modem NON-HLOS.bin
fastboot flash dsp dspso.bin
fastboot flash system system.img
fastboot reboot
This was the line of commands I used when my recovery mode was corrupt and somehow worked
I hope this helps and let me know if it worked or if the issue is still there. Also the forum has several posts on this matter and they might have the answer you are looking for as it helped me with this issue. Good Luck!"

HELP!! My red magic 3 is in bootloader bootloop

I flash the Chinese ROM to the global version of red magic3
And entered the boot loader boot loop
How to fix it?
If you try to flash system.img, tell me how to fix the problem that fastboot.exe will stop working.
I saw other threads, but I didn't know well because I was so nervous in English

"Hello, I have a problem. I flash twrp on my phone and wanted to flash from CN to EU version. I deleted the system and wanted to select the EU zip file. it did not work. That's why I restarted the phone. Now the phone starts only in the bootloader and the phone is no longer recognized by the PC although I have installed all drivers.

Followed a guide as stuck in boot loop. Now device is corrupt, help please.

Hi there, my device was having boot loop problems, I followed this guide using files uploaded by a user, then I was able to update using otg cable but it got stuck at 25%, after a reboot I get the message that my device is corrupt and cannot be trusted.
This is the guide i followed :
https://forum.xda-developers.com/red-magic-3/help/stuck-fastboot-mode-t3937527
Now I have tried to flash at fastboot the following images:
En_wpj0O_v115
En_wpj0O_v207
En_wpj0O_v209
En_wpj0O_v210
Chinese 2.31
I used the following commands each time:
fastboot oem nubia_unlock NUBIA_NX629J
Fastboot erase boot
Fastboot erase recovery
Fastboot erase system
Fastboot erase userdata
Fastboot erase cache
Fastboot erase data
fastboot erase system
fastboot erase modem
fastboot erase dsp
fastboot erase vbmeta
fastboot erase dtbo
fastboot flash parameter parameter.img
fastboot reboot bootloader
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash splash splash.img
fastboot flash modem NON-HLOS.bin
fastboot flash dtbo dtbo.img
fastboot flash dsp dspso.bin
fastboot flash vbmeta vbmeta.img
fastboot oem nubia_lock NUBIA_NX629J
fastboot reboot
Each time I've tried I just end up with the device is corrupt message, I have read that the command 'Fastboot flashing unlock' can solve the problem but when I enter it I get an error message that it's not allowed.
I would really appreciate some help getting this back up and running, maybe I'm doing something wrong or not using the correct images but I'm now at a loss.
Also my battery is now getting low which is worrying me.
Many thanks,
John.
Edit also followed this:
https://forum.xda-developers.com/red-magic-3/how-to/stuck-fastboot-mode-check-ub-debugging-t3951498
I used the files from global 2.31 and system.img uploaded by a user in that thread.
Then the following commands:
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash parameter parameter.img
fastboot reboot bootloader
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash splash splash.img
fastboot flash dtbo dtbo.img
fastboot flash vbmeta vbmeta.img
fastboot flash modem NON-HLOS.bin
fastboot flash dsp dspso.bin
fastboot flash -S 500M system system.img **I have to do it this way else it fails**
fastboot reboot
Unfortunately I still get the device is corrupt and cannot be trusted message. I am really stuck now
One thing I have noticed is when I flash system.img although it completes with all ok messages I cannot send any fastboot commands after doing this although fastboot devices shows the phone.
Should also mention that I cannot enter recovery from fastboot, just get the corrupt message.

Success.
I had to do:
fastboot flash -S 100M system system.img
Sending in larger chunks must have corrupted the image, I'm now back at the recovery and hopefully can go from here.
Update
Flashed latest EU rom over otg after clearing data and cache, all working.
What a relief!

Red magic 3 software crupt
My friend I'm facing same problem
I can't go to the recovery to restore flash file from usb OTG
Also fastboot is not allowed to unlock flash
How can i get back ok my device?

Having troubles re-locking the bootloader

I have been trying to re-lock my bootloader;
the first thing I did was use Lenono Recovery Assistant to restore the stock ROM, booted into android and all works fine.
Then I process to extract the files from the Stock ROM that LRA I reboot to the bootloader and run the command "fastboot oem lock" twice and it says that the bootloader is locked, but all it does is change from flashing_unlocked to flashing_locked and I still get the warning that "your device is running a different software version" alongside the verify mode disable".
Also tried to disable OEM unlocking in developers option and doing the LRA rescue and the nothing changes.
With flashing_unlocked it did allowed me to run this commands
fastboot oem lock
fastboot oem lock
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash boot boot.img
fastboot oem lock

Without error but again, nothing changes.
I bought this phone with Android 10 and there is only one version A10 for my region (AR)
Could it be that I need to try with Android 9?

Stuck with unworking Moto G8 Power [sofia] [XT2041-4]

Hi all,
I know this is an older phone but I received it used and I tried to place Lineage OS 17 from this forum on it as I did with two others and it did not work.
I have tried multiple ROMs from this forum but I always end up at the fastboot menu. I have tried fastboot oem fb_mode_clear and that doesn't work.
The bootloader logs state:
AP Fastboot Flash Mode (Secure)
Fastboot Readon: Reboot mode set to fastboot
I would be happy if I can get ANY de-googled AOSP ROM working on this phone.
Can anyone lend a hand?
I have used the LineageOS19 image from the forum and it includes a recovery image that I can flash and successfully access.
I have a twrp image that I can flash into recovery and also access, but it demands a password to decrypt the user data.
I have noticed that when commanding fastboot -w, the device reports that raw is not a supported format.
Anything else that I can give you to help?
Thanks!

"fastboot -w" doesn't work properly on mine either from what I remember. "fastboot erase <partition>" does.
Make sure you're not in fastbootd first: fastboot reboot bootloader
Then:
fastboot erase carrier
fastboot erase userdata
fastboot erase metadata
fastboot erase ddr
