[RECOVERY][3.4.0-13][avicii]Unofficial TWRP for OnePlus Nord (Testing)

Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
Code:
#include <std_disclaimer.h>
/*
*
* We are not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at us for messing up your device, we will laugh at you.

TWRP might never be as before and thats something we all have to accept. Google did some major changes and it will take some time to fix that.
I'm using my 7T now for more than a half year without fully working and stable TWRP. I still don't miss it. For root there are a few instructions and custom ROMs can be flashed with fastboot. Kernel can be flashed easily with Kernel manager. Let's wait and see...

For kernel flashing you need root.

Sure you will need to have root. but that's common and possible without TWRP.

Thanks so much to mauronofrio for that TWRP port!

Installed in few minutes.
Magisk installed with no problem.
Thanks dev!

Just installed magisk, too. Everything working like a charm!
Thanks mauronofrio!

KOSP is a small project based off AOSP and we intend to improve upon AOSP to provide a stable and better alternative to OEM roms with additional features.
Features
There are some cool features, see for yourself
Truth is I'm just lazy to write a long list of features and we intend to focus on the stability rather than adding a ton of features.
Gapps is included!
Note:
hotdog has dropped sdcardfs
We are enforcing and safety net passes out of the box
What's broken?
You tell me
Bug reporting:
DO NOT report bugs if you're running a custom kernel or you installed Xposed
Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
Do not approach us without any logs for reporting bugs
If it is a random reboot, grab everything from /sys/fs/pstore. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues.
Downloads: GDrive, Sourceforge
Magisk: https://github.com/topjohnwu/Magisk/releases

No.

Is this based on any of the two existing TWRP modifications for Poco F3 or is it a new approach? Reasons for asking is that they both come with their own type of bugs.

I have tried to take the good parts of all the existing TWRPs and add my own modifications to make the recovery more stable. There will be regular updates almost every week, so make sure to check the download link almost every other day. For changelogs of the latest build, You can check the pinned message of the support group

Woahh... Nice... my fave recovery since Redmi note 5 Whyred.
Hope next build also has feature to automatic reflash ofox after flashing a rom.
Thanks.... will try this after i get home.

The auto reflash ofox feature won't be implemented until the ofox source developers add it. Till that time, you can just select ofox zip in the "add to queue" option so that it will reflash after the ROM flashes

Works great so far, xiaomi.eu stable 12.5.19 (android 11)
In fact, it works better than twrp, to do a backup with twrp I had to run the rm data/extm - Rf before I could backup, but with orange fox, it works normally, no commands needed
Thankyou for your work on this sir

It really works. Xiaomi.eu stable 12.5.19. Backup also works, only restoration does not work ERROR: 255
Many Thanks

I don't know what black magic that guy has done to achieve that, since his trees are private (they are not on github) and I've tried contacting him 2-3 times. All I got was no response. And I myself have tried to figure it out on my own more than 5-10 times, still no luck. So I don't think I'll be able to implement a12 decryption until TWRP officially supports it.

You're doing a good job either way. Keep it up.
The only reason I switched back to twrp from orangefox was it woudnt virabte on touch so I couldn't figure out if the recovery is fully functional and I can start using it or its still booting.

you have posted several borked roms that wont boot.... you should personally test these before making a post

Only two, the actual rom in the thread boots and works, the second post which I asked for someone to test is perfectly fine I believe, nevertheless you are correct I should test first however I hate having to constantly reset.

Perhaps A13 bootloader bug. Will test and see.

Weirdly, the first build I did for A13 still works perfectly fine. Getting the same error as you for the recent build. Doing further testing.

Any chance for Oriole? Loved arrow on mine mi9t, perfect rom..

Other update, fingerprint works now, Switched over to EvolutionX has they are more up to date, Camera works perfectly on Arrow but not Evo so working on that, rom is very smooth.
