How To Guide Unlocking and Rooting Xiaomi 12S Ultra (Twrp/Magisk)

[Sathelp]

Worth first restarting the phone, some who get this error have this and a simple restart can resolve it. If not then check the twrp you are using. ( This taken from a post in the EU forum, Here )
BOOT / REC TWRP for some devices
For some devices there are different TWRPs available
1.) BOOT-TWRP -> fastboot boot twrp - boot TWRP only
2.) REC-TWRP -> fastboot flash recovery_ab twrp.img - install TWRP permanent
3.) BOOT-REC-TWRP -> you can use both fastboot commands -> see 1.) & 2.)

All the previous firmware versions are on Mifirm including the fastboot version. The twrp I used I kept a copy on my mega page. You are free to use it if you want from here, 129mb

And use command prompt, not miflash. I have never used it and never get issues.

Great many thanks! In fact, I did use Miflash fastboot ROM, worked as a charm, although it did give me an error. Never thought flashing ROMs might be so inconvinient in 2k22.
So glad I noticed "no data wipe" toggle

Later, I used the older recovery from first post and solved the issue completely

Now I have a question:

Recovery for Xiaomi devices - Browse /thor at SourceForge.net

List of relevant recovery in one place

sourceforge.net

Do you know whether recoveries posted here (basically from EU website) are REC or BOOT? Or how can I tell the difference?

 

[Sathelp]

One is temporary (boot) and the other is permanent (flash).
Boot twrp is normally but not always in an .img format and a recovery twrp is normally but not always in a .zip format.

Here is a link to a really good explanation.

I'm also glad that you are now ok and running.

Not really.

For this device there are 2 TWRPs and not 3 as you said above.#21
The Boot version which is not temporary if you use the following procedure:

Phone in fastboot mode
Command:
fastboot boot twrp.img
power shell
./fastboot boot twrp.img
then in Twrp go to Advanced -> flash current TWRP.

The REC version installs this way:
Either with the TWRP
Install select img/recovery/AB partitions
or
with the command "fastboot flash recovery_ab twrp.img"

No REC BOOT version.

And it seems to me that the link you post makes no reference to the BOOT or REC version, it's mostly general.
Currently the SKKK site is down, the proposed version is REC.

You obviously didn't read the whole page. And I only mention 2 twrp versions as I was asked about the 2. What is the third version I wrote about, recovery fastboot and what?

Please, if your only here to criticize posts rather than try to help people, then please ignore everything I post. I had no need to give any explanation but I did to try and help him, which I seem to have. I could have just sent him to the EU forum or tell him to Google the answer but no, tried to help. May be you can add something to assist next time.

This is a fix to avoid errors and indeed we are here to help, ask questions, provide content, without providing false or bad information because when you say the Boot version is temporary, you are wrong.

Will you be uploading v3.08 boot patched file for Magisk?

Thank you.
