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

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!

My Phone have a bootloob in the fastboot mode...
"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. Is there a special software that recognizes the phone or is the phone now forever defect? "
Thanks for the Help!

[FASTBOOT] [STOCK] [RMX1921EX] A16-Pie and C01-Android 10

Both the fastboot images does not have stock recovery at the moment. We were not able to pull that because magisk modifies boot.img and results in no boot. if vbmeta is flashed with --disable-verity --disable-verification, it results in persistent TWRP.
Ideally, you wouldnt have to replace anything other than system,vendor,vbmeta and boot. I have added them just in case you need them.
NOTE :
Android 10 is not backwards compatible with 9 firmware. So, once you open that can of worms, there is no going back for now.
Code:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img
fastboot flash boot boot.img

Can I root redmi note 9 updated to miui 12.0.3.0(QJOMIXM)

Hello
Can i root redmi note 9 (m2003j15ss) updated to miui 12.0.3.0(QJOMIXM)
I rooted the previous version (miui 11.0.5) with this method:
fastboot devices (check your phone is the only device shown)
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img (this disables system changes)
fastboot erase userdata (this will clear user data!)
fastboot erase cache
fastboot flash boot magisk_patched.img
fastboot reboot
But now I do not have the patched vbmeta for this version
Can i use the original vbmeta in rom for this command:
"fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img"
No problem?
Does not bootloop?

It works for me fine on miui 12.05 too. But now i use Lineage OS 17.1
You taken a risk rooting on a 12.05/6 version.thr company is pulling there security up.the first day off global 12.05 a few thousand people bricked there phone.before the end off the day they already removed the system security patch.the black market is a pain for xiaomi .if you screw up you're firmware.whell we are running on a mtk chip that's basically hoping that things can brought back. don't provide edl.if something goes wrong mtk signs in oh wait lock fastboot.its a unofficial twrp and not even for this device straight out off the box it's patchwork.If you go deeper in the updates it's just not the monthly security patch that's get updated.If you search around a lot off people can't get in recovery/fastboot and end up a hard brick.this is mtk related why is there no custum ROM why is there no eu ROM on the EU xiaomi mod base .why no twrp it's all mtk related .people should ask why I need root these days back in the old days ok I understand.If I ask people what you want to do with it then ?.Most don't give a straight answer or give reasons that you can do without root now a days.back up app data burn up the inside build most don't say that.
Yes, you can.
