I'm not sure. Maybe yes if your bootloader is unlocked.
You can try to flash this in MiFlashTool and then tell us, please ;)
But, certainly you can flash this in SP Flash Tool.
Well, the file format looks like Stock firmware fence the assumption. But I guess I'll go with SP flash since I'm a student and i can't afford to hard brick this

Yes, it has all flashing scripts.
Taken care for NOT flashing the flash_all_lock script or your device will be locked again.

Sorry for the Noob question, but what's Engineering rom? Its a custom rom? And what changes from miui?
Thank you
It is an OFFICIAL ROM by Xiaomi.
It helps engineers to make updates, bug fixes, new improvements and many other things on the device, because this rom does not have all the security steps and procedures.
In other words, it helps for DEBUGGING and DEVELOPMENT.

It is not OFFICIAL, it is not released to public. It has been released by Halabtech. and engineering rom is used as a base to build the stock rom for the device.
Also, please credit @ErdilS, as he provided the firmware originally.

Engineering rom is base firmware used by the company to test features and build stock rom for the device.

It is not for daily use, just for unbricking device.

YES, this is leaked but it is OFFICIAL developed and signed by xiaomi.
Only Xiaomi can sign images with xiaomi signature.
Are you insane?
Do you mean halabtech has any developer on its team?
LOL, LOL, LOL.
Halabtech is just a (good) copier.
I've never seen anything developed by halabtech team.
Except some bat files compiled to exe... LOL, LOL, LOL.
( IF ANYBODY NEEDS ANY FILE UPLOAED TO halabtech, JUST TELL ME AND I WILL PROVIDE THIS FILE TO YOU FOR FREE ! )

Hello mod, if i flash this Rom, i may repair imei null for my device?
I'm not a mod.
Engineering Firmware does NOT repair your imei.
It just allow you to enter in meta mode and use maui meta.
You need to do everything by yourself.
Talking about changing imei is not allowed on XDA, please don't ask about how to do that.
Good luck

If you can post FRP bypass threads on XDA, You can talk about changing IMEI too.

Still waiting for you to credit @ErdilS, he got this for Redmi Note 9. Remember that you did not find this yourself, we brought it to you. Even the screenshot you posted is mine.

Forum rules clearly state you are supposed to credit the source.
