I newer try update have From magisk becasu some file it's save in data. If you want update restore stock boot.img and then flash stock recovery. Now do it wipe I'm stock recovery and update again. But remember when you unlock frp you have locked on Android 7
For safety downgrade to b182 update all firmware to n391. I do it all time but first I backup my app using huawie backup

Thank you. I downgraded to b182 and updated all to b391.
Before trying again with Magisk i wanted to do a backup of stock boot and recovery, how can i do it without using TWRP?
Also to install magisk so that i can get OTA in the future how can i do it? Should i also install supersu PPH?

Seems that you can safely install TWRP over b391

AFAIK, for further OTA upgrades you need to keep TWRP nadroid backup and stock recovery, OTA would not work over custom recovery and rooted boot partition

For OTA updates you need stock recovery
Or download the full rom and flash thorthrough twrp
Yes i agree. You need one of the above mentions. Either you should have a stock rom or flash the whole firmware update version.

You should still receive OTA notifications with root. And it should detect you have root, and will download the full update zip, and it will install with TWRP.
Otherwise, you can manually download the full zip update from Funk WIzard's thread which he linked in Post #2 above (which also has detailed instructions on how to update when rooted and TWRP installed).
Works like a charm with magisk 13.6
I just did it with my OP3t and was super easy.
1) download update.
2) go to hidden folder .Ota
3) move zip file to another folder
4) put Magisk in the folder, too
5) reboot to recovery, flash ROM, then Magisk
6) wipe dalvik/cache and reboot
Edit: updated following testing of redpoint73's correct advice

As long as you already have TWRP installed (which is the situation we are talking about) you just need to flash the OTA update zip, then flash Magisk.
Magisk prevents TWRP from being over-written (replaced) with stock recovery. In other words, you don't need to flash TWRP, since TWRP is already there.

Yes.
Although I will caveat that with my rule of thumb: "hope for the best, prepare for the worst". In that a "dirty" flash of an update is often possible (saving your a lot of work setting up the device again). But you should still be prepared to wipe and do a "clean" install if you run into any problems. So back up your data, by your method of choice, before you try to update.
In particular, for a major update (such as OOS 4.x to 5.x) a clean install (default wipe in TWRP - data, cache and Dalvik) is typically advised.
Shall?? You used the word 'shall' properly in context? Kudos to the school system (I here assume India's) you attended, and to you for paying attention, using the 'King's English' in it's most proper form.

P10 Oreo system update (B365) on L29-C432B360+Magisk v16

Hello, I have a P10 L09C113 rebranded in L29-C432B360 and then rooted with Magisk V16 installed via TWRP 3.2.1-o by Blackball (https://forum.xda-developers.com/p10-plus/development/recovery-twrp-3-2-1-0-oreo-t3734993)
Today I received a notification about a system update to 8.0.0.365 via OTA (about 300 MB) on system settings app.
Is it safe to accept the update?
Or do I have to flash the stock recovery first?
Or do I have to uninstall Magisk before and then to flash stock recovery?
Or ?

Exciting!
I recommend this method as it will ensure it works correctly:
https://forum.xda-developers.com/p10/how-to/guide-manual-updgrade-to-update-oreo-t3758286
You will indeed need the stock recovery, and this method does it all for you. Simply re-flash TWRP and Magisk after its installed and booted once. Good luck!

at the end I flashed stock recovery and used Firmware Finder App.
In this way I downloaded the firmware from system settings app and updated successfully.
Now I will flash TWRP, but I'm looking for the best one:
 @Blackball that cannot decrypt /data or @espaciosalter20 that decrypt /data, but I don't know if is able to flash Magisk

TWRP 3.2.1-0 for P10 v0.1 from Pretoreiano80 works well for 8.0 ROMs (like stock firmware you have flashed.
(Blackball's is useful if you're exploring 8.1 ROMs (such as the available Treble images))

Thank you, but I read on thread:
Some of you have been reporting that mounting /system or another partitions doesn't work. I have discover that you need to decrypt data *before* to mount any other partitions.
I didn't set pin or fingerprint on my P10.
May I use this TWRP to backup and restore partition (system/boot in readonly image) and install Magisk v16?

The worst you can do is try. Seriously, backing up will not damage your system and if you see any errors then try a different TWRP version. You can flash as many of those as you like through fastboot until you find one that works for you!
Backup for sure, but flash magisk?
Could it corrupt system or data?

How to update without losing TWRP and root?

Hello, I have a Mi 9T Pro with 10.3.3, TWRP and Magisk. I received the update to 10.4.0. As stated in the title, how could I update the system without losing the TWRP and root through Magisk? Thank you in advance

You can't. The best way to update is to download the 10.4.0 recovery ROM, then flash that in TWRP. This will still overwrite Magisk, so you will need to install that again straight after installing the update. If you don't install Magisk immediately, then booting into system would also restore stock recovery, so it needs to be done before you reboot to system.

Many thanks! In this way I could at least save the TWRP! Should I have to take some other precautions? Like deactivate all Magisk modules, perform a backup of apps ecc?
i have the same question too..

No, you can simply flash the ROM and right after that, flash Magisk. This way you won't loose twrp or Magisk.

I would just add to this that, although this is all that is required, I would still backup things, just in case.
It's always good practice when flashing things to backup what you can, even when it's not needed should things go smoothly. It only takes an absent minded moment of stupidity in TWRP to do some serious damage. As many people, myself included, can vouch for.
Thank you everyone!
I've read a lot about this, some say it's better with fastboot rom and Miflash, but twrp method with recovery seems to be easier method.
Can anybody confirm is it necessary to remove compatibility.zip file from flashable zip file before flashing?
Clean flash or dirty should work for 10.3.4.0 update?
I'm using 9T Pro (EU), rooted, stock 10.3.3.0, TWRP 3.3.1-15

Flashing a minor update is fine to do as a dirty flash in TWRP.
Doing a major update is 50/50 (going from 10.3.x to 10.4.x as it's s change from Android 9 to 10, or going from 10.x.x to 11.x.x). You may be fine, you may have issues. It might be a better option to try using the 'save data' option in the Mi Flash Tool, which is the same as a dirty flash, but will still update vendor and firmware files, should they have changed between the versions.
You might be guided by what the OTA would do. Occasionally when an OTA provides a major version change, it will perform a clean flash and give you big warnings that this will happen first. If an OTA tells you this will happen, then I would definitely use the Mi Flash Tool and use the 'clean all' option.
As for the compatibility zip, it depends on the TWRP you are using. Just try as is first and if your get an error about the wrong device, then remove it and try again.
Thanks a lot, your answers are very helpful in this thread! ?
I got the OTA update to 10.3.4.0 on my Mi 9T Pro, too, but it wouldn't install via TWRP (mauronofrios version 3.3.1-15). I also tried to flash the full 10.3.4.0 ROM (https://bigota.d.miui.com/V10.3.4.0...EAGlobal_V10.3.4.0.PFKEUXM_964826982c_9.0.zip) with TWRP, but that didn't work either, not even after removing compatibility.zip.
I then changed my TWRP to OrangeFox Recovery 10.0_7 stable (via fastboot) and dirty flashed the full ROM via OrangeFox. That worked flawlessly, it even seems that it will be able to install future OTA updates, but that remains to be seen when the next OTA update arrives.

You need to confirm if orangefox is actually ready for OTA by checking in its settings.
