Hello! I'm a complete beginner when it comes to this, please bear with me. I don't want to brick my new toy!
I'm currently in day 5 of waiting to unlock bootloader.

Q1: When you install the custom ROM via fastboot, can I update it via OTA?
The last fastboot version for POCO M3 is xiaomi.eu_multi_POCOM3_V12.0.3.0.QJFMIXM_v12-10-fastboot, but I want to be updated to xiaomi.eu_multi_POCOM3_V12.0.4.0.QJFMIXM_v12-10

Q2:
If not, can I just install the fastboot version, install OrangeFox, then flash the latest version via OrangeFox?
I want to install the Xiaomi.eu ROM first because apparently there's some problems with the stock ROM and OrangeFox.
Q2.1: Am I making the process too complicated?
Q2.2: Can you suggest a better, easier, and faster way of installing the Xiaomi.eu ROM, a custom recovery, and Magisk for root?

That is all for now. I might ask some follow up questions though, depending on whether I fully understand or not :) Hopefully that is tolerable.

Hello, newbie! :p

Q1: You can update ROM via OTA only if you have a working custom recovery (TWRP, OrangeFox, etc.) installed in the "recovery" partition of your device... ;)

Q2: ... So you can simply install OrangeFox (if available for your device) => Format Data (it's the button's name in "Wipe" menu and you have to type 'yes' to confirm it) => Reboot to "Recovey" => Install latest xiaomi.eu ROM (then Magisk v21.4, if you want to be rooted) and reboot your device. :)

Q2.1: Yes, a little bit. ^^ You really don't need to install the "fastboot" ROM version.

Q2.2: Don't know what you mean by "faster way". :D

Hi!

Yep. This requirement seems to be satisfied since there's already unofficial versions of TWRP and OrangeFox for the POCO M3. Nice.
Q2: ... So you can simply install OrangeFox (if available for your device) => Format Data (it's the button's name in "Wipe" menu and you have to type 'yes' to confirm it) => Reboot to "Recovey" => Install latest xiaomi.eu ROM (then Magisk v21.4, if you want to be rooted) and reboot your device.
I do format data in OrangeFox first, reboot to recovery, then what I'm guessing I need to do here is connect my phone to my PC to transfer the Xiaomi.eu ROM and Magisk to my phone's internal storage then continue. Is this correct?
Q2.1: Yes, a little bit. ^^ You really don't need to install the "fastboot" ROM version.
Beginner mistakes :)
Q2.2: Don't know what you mean by "faster way".
Well, I was thinking of a procedure that's less complicated that what I have in mind right now, which is:
  1. Install the last Xiaomi.eu fastboot ROM
  2. Install OrangeFox via fastboot
  3. Install the latest Xiaomi.eu ROM and Magisk v21.4 via OrangeFox
But as you said, OTA works when I have a custom recovery installed so step 3 isn't necessary, just for Magisk only. Thinking of reversing the steps too.

FOLLOW UP: Would removing my lockscreen password and fingerprints solve this "encryption" problem TWRP and OF for the POCO M3 currently have?
Apparently the stock ROM has problems with encryption/decryption, resulting in gibberish folders while in recovery. This is the reason why I want to install the Xiaomi.eu ROM before OrangeFox, as that ROM doesn't have the mentioned problems. If yes, then I can follow your advice from Q2.

I don't know for your device but maybe you can only use pattern instead of pin/password (for now). Pattern, instead of pin/password, can work for decrypt /data partition in TWRP/OrangeFox.

Follow my advice from Q2. ;)

Okay, thank you very much. I think I'm ready. I'll be following what you said from Q2. Wish me luck, and I hope to bring good news by February 3.

Good news! I was able to successfully install OrangeFox, Xiaomi.eu, and Magisk :) Not without regrets though, I tried using adoptable storage and I regret it, will reformat the SD card as external and do a factory reset in OrangeFox again. Factory resetting doesn't erase Xiaomi.eu, right? After formatting I can just reboot to system?
