How to flash official stock rom after an older stock rooted rom - Redmi Note 9S / Note 9 Pro (Indian Model) Question

Hello I have a rooted phone with official miui12 rom.
TWRP is flashed but I can also run TWRP using adb.
How can I flash the New miui13 stock version ? Do I use the official Xiaomi flash tool? Or do I use TWRP to flash the stock rom?

Through fastboot, you should use the fastboot ROM, and through TWRP, you should use the recovery ROM.

Thanks. A preferred option ?
Using TWRP do I need to erase stuff before or can I install directly the rom and this is all ?
I guess that recovery room is not the one provided officially by Xiaomi, right ? It the same but packaged a different way ?

---

Do you know if SD card will be erased during the stock rom flashing process ?

---

I see on official Xiaomi site that official rom is quite old. Miui11 version so I guess I will need to perform a lot of OTA update... Can I trust recovery rom provided on other websites to have the latest stock rom version ?

Normally, you don't need to erase data, as they just update without erase per se.

As I said you, there are two official versions, the fastboot and the recovery ROM.

The OTA updates come, either in form of fastboot or recovery ROM, when Xiaomi provides an update, you will, also, find the minimal OTA package, yet included in the whole ROM.
In this site, you will find the most up-to-date releases https://xiaomifirmwareupdater.com/archive/miui/joyeuse/

thanks. I would like to be sure that my flashed TWRP will be erased during the process, will both flashing process (fastboot or TWRP) erase all my phone and put in a new "clean" state ? (except maybe for sdcard content)

Nope, both the processes, don't wipe per se, either through recovery or fastboot, in the Mi Flash tool, there is an option to format data, if you like it, if not, it remains un-ticked.

Sorry to insist but what are you calling 'data' ? Is it the SD card content (I don't think so) or is it the data partition on my internal memory ? So it could be :
Photo taken in internal memory
Data stored by apps like photo from WhatsApp or stuff like that ?
Temp file of each app like settings of app, etc.
Would it be a problem if I erase all my phone and loose all my apps but data off app are still there, it will take space for nothing right ?
What about flashed TWRP? will it be removed by the flashing process ? I think TWRP is flashed in recovery partition but not sure.
As you see I'm not familiar with android partition even if I did several times this kind of process with different phones.

Not exactly what I call data, but, what data means in Android World.
Formatting data, it's deleted all the data from apps stored in /data partition, all the data regards settings, all the apps installed by the user, general configurations and all the data stored in internal storage, also the system apps uninstalled by the user can come again.
As per the SD Card, if you have one inside, it is not touched in the process.
If you flash the recovery ROM using TWRP, it won't be overwritten, if you flash the fastboot ROM, you'll lose the access to TWRP.

Thanks. Tell me if I'm wrong but if a choose to flash stock miui 13 version whereas I'm currently in miui12 I should maybe erase data also ? Maybe apps won't works again from 12 to 13 version ? I should be cleaner to reinstall them again don't you think ?
About fastboot stock rom isn't it strange that the official website provides only miui 11 rom whereas your site has miui13 version? How is it possible ? For recovery rom I understand because people can backup their phone and could create a recovery rom like this with miui13 after doing the ota. But for the fastboot rom, if Xiaomi don't provides it and provides only miui11 one, where does the miui13 come from ?

It would work even if you don't erase data, but, I personally prefer erasing it, to avoid some lags/bugs in the future.

Firstly, be sure that your device is Joyeuse.
All the updates, either recovery and fastboot ROM, are provided by Miui, all of them are official updates, not uploaded from users´ devices.
It's A12, not A13, I don't think your device see the light on A13.

Yes android 13. But miui 13 comes with android 12 and my current os is miui12 that comes with android11. (If I'm correct).
I have Redmi note 9 pro, M2003J6B2G (photo is 64M). I don't know where Curtana or joyeuse word can be really found in my phone but after some readings I had the feeling that M2003J6B2G = joyeuse version.

Xiaomi also could update the Miui version, so Miui 13 came with Android 11 for some devices, don't stay there, just check the Android version that is specified in a tab, at the download list.

There are some apps like Device Info and other similar, from Play Store that can tell you, exactly, which your model is, Anyway, Redmi Note 9 Pro is Joyeuse but, be sure, before to proceed, consult some app like the mentioned.

Cpu-z indicate joyeuse-eea. Should be good.
Ok so I will delete the data partition and I will use fastboot flash using Xiaomi tool. I'm not sure to understand your answer about the SD card. Will it be erased during the process ? I know that sdcard are now crypted so that they could be used only by my phone. If the os is modified, maybe I won't be able to read it even if it is not formated. Don't you think ?

Just to not confuse, sdcard is the internal memory, that is symlinked as /data/media/0, all the internal memory is gone when we format data, some folders are recreated at the first boot, after performing it.
SD Card refers to Secure Digital card, that is an external media storage, it is absolutely excluded to any operation from Android, when flashing, updating the system or formatting data, of course, you should consider that some apps like camera can store its pictures there, previous authorization from user, but they will stay there yet, and some folder can be created too, at the first boot, but nothing that harms.
Just to know, sdcard as internal memory is not encrypted at all, it's accessible for any user, always, that can bypass the locking feature of the choice of the user, i.e. PIN, pattern, etc.

Thanks I didn't know that sdcard and SD card weren't the same. My concern is about external memory card (SD card). If not formated. I'm afraid that it couldn't be used after reboot. Except if the decryption key is linked to my phone (hardware) and not the software part (os) of my phone

The encryption is permanent since A6, it remains, at least, you can do something about it, using a custom recovery, a custom module, script, or something, nothing that the end user can worry about, for the normal use of the device.
Trying to guess, you did encrypt your SD card, then the encryption key is linked, only to your SD card, the SD card, specially, in newer Android versions, is treated as a privacy media user concern, so every time more, apps can't access to, as easy as the older times, it is RO by default.

Sorry I have difficulties to read and understand your last message as my English is bad.
Especially the second part... I don't encrypt anything myself. I just now that recent version of Android encrypt the sdcard and it couldn't be used in a computer for instance or another phone. So I think that maybe after new rom flashed. SD card won't be read or write from the phone and I will have to format it myself so that I can read it from my phone. Correct ?

You are again mixing the terms, in the first part, you're saying "...recent version of Android encrypt the sdcard" and linking to the second part, you're saying "...after new rom flashed. SD card won't be read or write"
As I said to you previously /sdcard AKA internal storage is not encrypted at all, at any time, the fact that you need to authorize the MTP connection within your device and a PC, doesn't change that, if you or anyone else, have access to the Android interface, then you or anyone else, can see all the data/files/pictures/audio/video stored, in the internal storage, by using a file manager app, or a specific app for every file instance/format, i.e. a music player for videos/sounds/musics, a gallery app for pictures/images, and so on.
As per the SD card, the same, if the user (you, in this case), didn't encrypt it, then, Android, also, doesn't encrypt it, so you and anyone else, can access to the data stored in it, either during the OS functioning normally, and/or after the flashing/formatting process.
