I installed LineageOS 18.1 (Android 11) on my OP7P and want to boot (or flash) TWRP.
There is a lot of different information about the state of TWRP on Android 11.
I hope someone could clearify the following questions:
1. Does TWRP [3.5.2] support Android 11?
the release notes of 3.5.1 state that they "prepared a mini release before Android-11 support."
The release notes of 3.5.2 don't mention android 11 at all.
There are various people in the LOS18.1 thread that can boot twrp, so I assume there is some kind of (partial) support.
2. What if 'fastboot boot twrp.img' doesn't work?
For me I can't boot (or flash) TWRP (on LOS18.1).
So as the twrp/lineage os guide says I do:
fastboot boot twrp.img
Click to expand...
Click to collapse
It finished succesfull, but my phone stays in fastboot and doesn't reboot.
The TWRP guide says the following:
If fastboot boot command doesn't work you need to root your device and flash the TWRP installer (remember that flashing the TWRP installer you will lose the root).

I find this a very vague description; what do they mean with "doesn't work"?
(when I flash twrp it results in an unbootable phone, might be related to a/b partitions, but I have not enough knowledge of that)
3. Does TWRP work on encrypted phones?
I found various posts that suggest that TWRP doesn't work on encrypted phones.
I can't find any reliable source that supports that statement.
Twrp says this, but that doesn't clearify things at all.
I hope someone could give me some answers, or guide me to some reliable source so I can find it myself.
I find the documentation of LineageOS and TWRP lacking in that perspective.
For question 1, there's no official TWRP for 11.... YET.
Question 2 - I'm thinking cause TWRP doesn't work for 11, that's your issue.
Besides that, if your trying Android 10(because you don't mention what version your using in question 2), I would suggest re downloading, as that process works fine for this phone I'm typing this reply to you on.
Question 3 - I'm sorry, I've got ideas, but it's above my pay grade... So no hard knowledge I'm comfortable calling advice, to give a fellow OP7P owner.

I also think there is no official TWRP for android 11, but twrp doesn't make this very clear in their docs.
Multiple people are claiming they are able to (at least) boot twrp on Android 11.
LineageOS 18.1 is Android 11 (but I will clearify the post).
Thank you for your reply
there is now a working TWRP version for Android 11.
Nebrassy version: https://forum.xda-developers.com/t/recovery-11-unofficial-teamwin-recovery-project.4289455/
worked for me with 'fastboot boot TWRP-3.5.1-guacamole-Nebrassy-3.img'
I just rooted my samsung s10 G973F / DS via Magisk (not without some bootloop issue and a couple of times I had to flash the stock firmware and then the patched one).
I would try to include havoc custom rom which has great reviews for wanting twrp first.
So that the March 2021 update for Android 11 support is out, but I need a guide, in fact I wonder if I flash the twrp 3.5.2. from odin, do i need to reinstall magisk from recovery twrp or is my root safe?
Thanks to who will answer me!

Have the exact same question in mind. Hopefully someone will respond soon
I already know how to install the unofficail TWRP firmware for my Pixel 4a but it goes back to the custom roms recovery or stock recovery almost every time even after installing ramdisk. What's going on?
Since you are on Android 10, I don't think there will be anymore OTA updates because I think they are only for android 11 at the moment.
To get TWRP to "stick", you probably need to install a custom kernel that has ramdisk built into it as shown in this guide:
[GUIDE] UNLOCKING, DOWNGRADING TO A10, TWRP, ROOT
Hello, I'm posting this guide for those (like me) who can't do without TWRP on their device. I'm providing only a step-by-step explanation. Credits to @nikamura for his kernel and TWRP...

Tired of miui, always been a stock android user till now. Needs guidance on installing PE+ since the twrp now supports encryption. Some people says that twrp gets replaced by stock recovery if i dont flash magisk and root it. Since the safetynet support comes prebuilt in PE+, i dont feel like rooting as what im searching for is a fluent stock android experience. Can i flash PE+ as soon as i flash twrp? Is there any recomended firmware need to be added before the rom file? Miui in my device is currently on 13.0.3. should i flash the same firmware again before adding the PE+ rom?

Whether the Twrp decrypts or not is irrelevant since for the first installation you will have to format the data (TWRP/wipe/format data type yes/reboot TWRP).
For the firmware use the one that corresponds with the date of the rom or more recent (global if not specify another).

So should i flash the latest firmware thats available for my device that is 13.0.3 for miui? Should the PE+ work efficiently with that firmware. What do you mean by the requested firmware not available? Can you elaborate on that specifically? Requested by PE+ you mean?

Nope,since you already have it.Global not EEA
I haven't seen any instructions for the firmware so it's assumed it's the latest.
Older firmware will not work, newer ones will.
For some AOSP the OP asks to flash a Chinese firmware for example.
Either way if it's not the right firmware the rom won't boot or work properly.
Ask on the thread of the rom you want to install.
As suggested by @NOSS8, Get the latest TWRP/OrangeFox (based on TWRP, a beautiful recovery) but be advised A12 encryption/decryption is still in beta (but is pretty stable IMO). Usually one flashes the latest Chinese firmware, no harm in flashing it even if you are switching over from MIUI.
I AM NOT RESPONSIBLE IF YOU MESS UP YOUR PHONE!!!
YOU HAVE BEEN WARNED!!!
Watch dogs is a ROM I created and it started with the OnePlus 9 Pro back in December. I have decided to bring it to the OnePlus 9, it's based on LineageOS & crDroid source & dependencies and I thank them for its use. SafetyNet and CTS passes whether your rooted or not. Modules not required. Most features are the same as crDroid but I have made some adjustments to bluetooth quality and some fonts that are not available there, plus Gapps are included.
Before you begin, if you don't have the latest platform tools installed on your windows machine. Download it here:
DO NOT FLASH GAPPS!!!! THEY ARE INCLUDED IN BUILD!!!!!
Flashing Instructions
First time installation (clean flash):
This update requires OOS 13.1 - 13.1.0.500(EX01) firmware
Backup your data
Download the ROM, and firmware flasher listed further down on this post and place all in your platform tools folder,
Extract all the contents in platform tools, Firmware flasher in folder.
You must flash firmware in bootloader.
Boot to recovery and factory reset then adb sideload
adb sideload WatchDogs-13.0-20230625-lemonade.zip
Reboot to system
reboot to recovery if you want root
adb sideload magisk.apk or adb sideload magisk.zip
Reboot to system
Update installation:
Updates can be sideloaded with custom recovery. Updates do not appear in system updater.
Sources:
ROM
Kernel
Downloads:
ROM
FIRMWARE FLASHER
Bugs?
Let me know.
Initial builds
WatchDogs-WITHGAPPS-13.0-20230312-lemonade.zip
WatchDogs-NOGAPPS-13.0-20230312-lemonade.zip
If you require Google apps, flash the first one only!
If you do not want Google apps, flash the second one only!
You can't cross dirty flash a update which should be common sense. Example, you can't dirty flash the with gapps build then next update, dirty flash the no gapps one.
I tried CRdroid recovery and the one I was on and both said name mismatch. Got any suggestions for me to try? Thank you for the new development too!

That's weird. Did you try sideloading the firmware flasher first before the ROM? If you still have difficulties, I will post the dtbo, boot and vendor_boot files for you to flash to make it compatible. I don't have this phone. I have the OnePlus9 Pro so I can't test it. I'm sure it works or there would be other users saying the same thing.
I flashed the firmware successfully and tried it again but still got the same error. It wouldn't hurt to post the kit files and recovery for others too. If you do then I'll try again before I have to head into work in a couple hours.
UPDATE:
I used the CrDroid boot-20230106 file and then sideloaded fw_Oneplus9_IN_OOS13_F20 on both slots and was able to flash the rom on both slots successfully. Will let you know what I find in time and thanks again for another version rom to pplay with

Good deal, and no problem. Since I use crDroid sources, I figured that should work. I will still post the files necessary to flash recovery when I get a chance. Let me know if there are any bugs or issues with the ROM itself so I can work on it. Thank you!
I installed it on my first try without any problems. but I couldn't understand how it differs from crdroid.

Not to mention Gapps included if you choose it so OTAs with no issues... otherwise you'd have to sideload Gapps again after at least for me that's what was happening.

correct, sorry, forgot to mention that as well. Thank you!! crDroid doesn't offer a with gapps build. You can use the no gapps build to flash your own gapps but I won't support force close issues with the ROM. Example, pixel setup wizard can't be used because it interfers with the default launcher. And yes, on updates, just sideload the with gapps build and your done, unless you want root, then you will have to reboot and sideload magisk because root will be gone on a update.

Convert your T-Mobile to EU as listed on another thread, then you can use the EU firmware. I will be posting a update soon with the boot, vendor_boot and dtbo. If you don't want to do that, I will post them later to flash recovery on your phone. Keep in mind that different variants act different, so you may have bugs on T-Mobile, it wasn't tested.

You can use my custom recovery, files added in OP. You still need latest stock A13.
fastboot flash --slot all boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash vendor_boot vendor_boot.img
You cant install this (or any rom but base 11) on tmobile 2117 without BL unlock key. Pretty sure its not possible.
You can only convert to base global 11\OOS11 on 2117 for root, then in ui updater doesnt work OTA or manually. You can get to 13 stock only, because you need to be stock to ota, where you need a key to unlock bootloader again (conversion would bring you back to 11).
*The rooting situation with this phone sucks. I think Jaguar is the only one that will work because it is base 11.
