how to reflash your original ROM back?

Answering my own question and for others who may need to.
Make a nand back up if the following in twrp.
Data
System
Boot ramsisk
I tried to install a treble ROM but I think the twrp version i'm using didn't allow it.
Going to hope that a compatible treble twrp is released or we are screwed for treble ROMs and let's be honest that's our last hope.
OR
Boot to eRecovery and recover from there, you'll lose all data and recovery but you will retain bootloader unlock.

Xiaomi.eu OTA update

Hi guys,
I'm on xiaomi.eu 9.1.24 and today I've received a notification to install 9.2.15. Is it possible to normally update my phone rather than following this method "https://xiaomi.eu/community/threads/9-2-14-15.49206/" that would wipe my data?
I was thinking about flashing stock recovery and run the update.
If you are on Xiaomi.eu, how do you update your phone?
Off-topic: for me it's impossible to flash staff via twrp from internal storage because it shows numerous "weird" folders instead of showing the right ones.
(It seems to me it is (like) encrypted)

I just flashed it in twrp, no need to wipe.

How to flash Magisk on Nougat?

Hello. Just got my phone back from assistance and had my motherboard replaced after an unrecovable hard brick.
Atm I'm on Nougat and I don't plan to update to Oreo, I just wanna root my device again and I would like to do so using Magisk.
So, I've unlocked my bootloader, flashed TWRP 3.1.1-0 and then tried to flash Magisk 19.3 zip: problem is my phone is encrypted so it requires password for encrypting and it fails (as expected), then it wanna do a factory reset and reboot into TWRP which is unable to factory reset properly while eRecovery doesn't have a factory reset option so meh.
I didn't had problems installing Magisk on Oreo but right now I'm pretty tired and cannot figure out what I'm doing wrong on Nougat. Any hint?

How is that you can unlock bootloader in these months?
My father give me the BLL23, and is on stock Rom (nougat)
But I want to try Viper, and that's making me need root, then I need to unlock...

Have you tried Ianmacd's builds? They're friendly with Huawei devices. Sincerely it's weird that official Magisk doesn't work since that topjohnwu has fixed troubles with EMUI some time ago, but give it a try. And here's a dedicated wiki in way to troubleshoot most common errors.
Plus, in way to factory reset as the OS asks, stock recovery is needed as you'll know. Even if the phone is encrypted a password shouldn't be asked after flashing Magisk. That usually is asked by recovery, so i don't know about this.

question about A12 roms

noticed we've had some A12 roms for a little while now and for some reason now instead of flashing them, all of them seem to be sideloaded and using that roms custom recovery to sideload it instead of using something like twrp and normally flashing it. any reason this is the case with A12 roms? and is it possible to downgrade from an A12 rom back to OOS 11/10?

The reason for the sideloading is that there's no working version of TWRP for A12 that can decrypt the data partition, hence lineage created a custom recovery and I believe everyone else has copied it. As for the downgrading, you may be able to sideload a stock file, but I'd use the MSM tool to get back to OOS, although you should keep in mind you will need to unlock the bootloader once again.

Help making a Backup before installing magisk+twrp OP8 IN2015 - already unlocked bootloader.

Hello! I've been rooting and installing custom ROMs for years but it's been a long while since I last did it, I got a oneplus 8 global (IN2015) late last year, unlocked the bootloader as soon as I got it out of the box since I knew eventually I would want to flash some stuff. but I have kept it stock this long. Running latest Oxygen 11 android 11
Since I want to start flashing some kernels or roms I wanted to ask about making a backup since I've never had a phone without sd card slot where I would usually store backups.
Can I still use titanium backup to keep all of my apps/data/photos/videos and the state they are in, store it in my pc , then go about flashing a custom Rom and then bring my titanium backup back into the phone and restore everything?
since I'll be installing custom roms based on android 11 I believe it will be fine with no conflicts? or does it matter that my apps were installed in Oxygen OS?
that's what I used to do with older phones anyway. is there a way to flash a rom while having the titanium backup still in storage since most roms require full whipe when clean installing them?
Recently twrp added official support for OP8 and when I open the official app it recognizes my phone as instant noodle but when I click search for phone it says it can't connect to the server? should I flash official twrp from the app or via fastboot? which I'm also quite rusty with.
any tips for a step by step would be appreciated

Hello, I was in the same boat as you since I came to the OP 8 from a Galaxy S4. Titanium backup should work for what you want to do, as long as the custom rom is also based on A11 (disclaimer: I haven't tried it; I'm running rooted stock OOS 11 with a custom kernel). If the rom you want to install requires a data partition format, you can't keep the backups there during the flashing process. If it only needs a data wipe / factory reset, everything in the sdcard directory (also known as /data/media) should be preserved.
I'd say just flash TWRP in fastboot. Flash it to both recovery slots, and read up on how flashing works with A/B slot devices if you aren't familiar, since you'll need to know about it when flashing roms also. It's a big difference from what I was used to with older devices.

Thanks for the reply, yeah I was thinking of just going with a custom kernel since I have so much stuff going on the phone I find it really a chore to backup, but still might want to try it.
What kernel are you using and how are you liking it ?
