This is insanely good! The thought of using Magisk to flash TWRP recovery is genius. Makes it soooo easy. Now you can just take the OTA, install Magisk via OTA, reboot and flash TWRP installer in Magisk and reflash Magisk (Direct install) reboot and BOOM! Or you can take the Full ROM zip flash in TWRP and reflash TWRP and Magisk before reboot and all is good too.

Thanks for all the work!
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Nekromantik:
I personally think its bad relying on Magisk for TWRP install.

You should not need root to install twrp.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] mauronofrio:
Yes there are some minor bugfix need to flash stock oos or h2os

Updated my platform tools prior to doing any of this from android SDK

Tried to run the following commands and keep getting this error

What the hell am I doing wrong here?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] reaper000:
Thanks for the quick reply!

Interesting. I flashed both stock 9.5.4 and stock 9.5.6 using TWRP 3.1.1-2 without any problem. Maybe I was lucky...

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Nikhil:
This way, you will at least end up on a recovery that works with encryption. After which you can dirty flash the rom and as long as you don't wipe /data your data will not be impacted.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] warezxts:
Thanks again. Do you have link to LineageOS on guacamole boot.img file? A11. I don't wanna f* up with wrong version. But first i will try the nebrassy TWRP. I remember long time ago i tried it, but there was something wrong. We will see.

Anyway my ROM version is the latest A11 (no idea about version number)
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Nikhil:
Here you go:

LineageOS Downloads

download.lineageos.org

I would flash LOS 18.1 recovery being on A11.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] truevapor:
Hello, sorry, do you have any ideas how to do the same on OOS A12?

After an unsuccessful installation of the Magisk module, my phone stopped loading beyond the Android logo. (this happens in both slots) I can't run the official 3.7 recovery on my guacamole and my data is also encrypted.

I keep waiting for TWRP 3.7 to work with OOS A12, but maybe there are some other ways?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Nikhil:
Have you tried flashing unofficial build from nebrassy?

Also you can try Los 19.1 recovery from my last post.

If you're able to get into recovery, you can try uninstalling magisk that would also uninstall the impact it brings through modules. And you should be able to boot, then you can flash Magisk normally.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] truevapor:
Thanks for the answer.

Hmm, then I'll try the unofficial nebrassy + recovery builds from linage OS again.

Only original recovery was flashed in the system after update on OOS A12. I can't start any recovery using the "fastboot boot recovery.img " command. I tried flashing the original boot from my ROM, but that didn't work either.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] riedenthied:
Where can I find this unofficial TWRP by nebrassy? The one at twrp.me seems to be from nebrassy, too.

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] truevapor:
Nikhil, I managed to run Lineage 19.1 recovery, I flashed boot.img from this ROM, then I tried to flash the unpacked OOS A12 (h30) via fastboot (flashing each image in turn), but my device does not boot beyond the Android logo ...
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Nikhil:
Did all the steps execute successfully?

I would use MSM tool to get back on stock and then upgrade to a12. If you check nebrassy's twrp thread, you'd get more idea on which version of twrp works fine with a12 and what are the workarounds of known issues.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] truevapor:
Yes, after flash all images get status OKAY.

I have almost completely read the information in the Nebrassie chat and on the forum, but the fact is that there are important data left on the device for which there is no backup, so MSM is not suitable yet, but this is probably the only solution if a recovery supporting decrypt is not released on OOS A12.

But thanks anyway for your answers!
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Nikhil:
Were you on any custom rom or OOSA12 only when you were stuck on boot up screen?

If you were on a custom rom, flashing all the images of OOS 12 is not a good idea as you'd be playing with encryption methods.

OOS12 is fbev1 and many custom roms are fbev2.

If you were on OOS 12, flashing lineageos recovery and within fastbootd of the recovery, flashing oos12 on both slots would boot up for you. You could also flash the recovery flashable oos12 file as an alternative to flashing via fastbootd.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] truevapor:
No, I've only ever used OOS, never flashed custom ROMs.

This is strange because I did exactly as you wrote and I still get the Android logo, and no OnePlus boot animation. Can Magisk files still interfere with startup?

I didn’t quite understand what kind of file we are talking about "recovery flashable oos12 file", if possible, then attach the link please. (in the unpacked OOS H30 there is no recovery.img)

Download: OnePlus 7 and 7T series finally receive stable Android 12 update with OxygenOS 12

OnePlus has started rolling out the long-awaited stable OxygenOS 12 update to the OnePlus 7 and 7T series. Read on to know more!

www.xda-developers.com

This is what I could find with a quick search, you can look deeper into the web to find the latest H30, this one is H28 I think. Just search by recovery flashable oos 12 for oneplus 7 pro.

And yeah, magisk modules can impact your boot, I've seen modules that touches the boot.img to retain the installed twrp so anything is possible. You must only flash the modules coming from the developer that you truly trust.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] khalisz:
I tried to flash oos12 from TWRP 3.7 and it absolutely doesn't work.

It stuck on boot with OnePlus logo.

I have done a full reset with MSM tool. update to OOS11 latest.

Then Unlock BL, flash TWRP 3.7, copy the full ota OOS12 into the phone.

- Reboot to TWRP, Flash OOS12.

- Boot

- Stuck on OnePlus logo, or boot loop.

Also I tried to juste update to OOS12 and it's impossible to unlock the BL.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] truevapor:
On my forum I recommend this method:

- Unlock the bootloader on OOS 11 (if your need)

- Disable all Magisk modules before updating

- Update locally (from settings) via zip

- Not reboot after updating the firmware, install Magisk in both slots (active and inactive)

- Reboot

Try this metod, if magisk was not previously installed and the system is clean, you can skip the magisk item, as far as I understand
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] khalisz:
Actually, my 7pro is already unlocked with TWRP 3.7 + Magisk.

Okay, I'll do it and will let know you.

Maybe today or in a few days (need time).

Hi All.

Updated my Guacamole OP7Pro to Android 12

Version : OS 12.1

Model : GM 1910_11_H30 ( ROM Eu )

Question: now I losed Root ! then I got Full Stock

I need to get FULL ROM because I want Root without TWRP.

I would Patch Boot.img to have Magisk and Root without TWRP.

Can anyone help me to find FULL Stock ROM ( my version ) to download?

Thanx in advance
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] foomo:
Is this TWRP 3.4 or the official TWRP 3.7 version working an Android 13 (eg crDroid 9)?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Jenjop:
Got stuck in a weird situation and wondering if anyone has ideas.

Current State:

Slot_A on OOS 11, can boot TWRP via Fastboot

Slot_B on OOS 12, can only boot into Fastboot

Originally on OOS 11, booted TWRP and made backups of all partitions (data, boot, system image, vendor image, etc.). Forgot to move this to computer so this is all still stored on device.

Proceeded with OOS 12 upgrade (into Slot B). Patched magisk, rebooted, then flashed TWRP 3.7 (FBEv1), direct installed magisk, rebooted. - Everything was functional, but decided to go back to OOS 11.

Thinking I could just use the TWRP backup made on OOS 11, I did the following:

Booted into 3.7 TWRP

Restored the backup for boot, system image, and vendor image

Set active slot to Slot A and reboot

It doesn't allow me to boot into the OS (Presumably because the data was re-encrypted for OOS 12?)

Set active-slot=b and reboot, but it's locked to fastboot.

I've attempted a few things, but I can't boot back into OOS. I would prefer to retrieve my TWRP backups first before doing an MSM reset.

When on Slot_A (older), I can only boot into TWRP 3.6.2 and 3.7. I'm guessing 3.6.2 can't decrypt since it's only configured for A11 and under, but not sure why 3.7 can't decrypt my data.

- It doesn't even ask for pin when TWRP launches; maybe it's reading the System for Slot_A and thinks i'm still on A11?

- running `twrp decrypt {pin}` doesn't seem to work. Unsure if there's something done to my lockscreen pin to be used as the encryption key/password?

When on Slot_A, attempting to boot into either the system or TWRP hangs.

Things I've tried:

Flashing A11 boot.img and magisk-patched boot.img to Slot_A -> Hangs on 1+ Spinning dots

Flashing A12 boot.img and magisk-patched boot.img to Slot_B -> Hangs on 1+ logo (Does show up on ADB though)

Booting Slot_B into TWRP 3.6.2 (Official, and Nebrassy unofficial for A12) and TWRP 3.7 -> Gets stuck on "Fastboot Mode" screen (fastboot cli still responds) or Hangs on snapdragon logo

Any help would be appreciated

Edit: Ended up using MSM. Needed device for work

I was able to get root and install TWRP following the instructions provide. - Thank you very much!!

I am on 9.5.4 and an update is pending. Is there a process to update without loosing root or recovery?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] schmeggy929:
So this will be the 4th time, I'm writing this through the forums. Lol

Already rooted. Disable any Modules that require certain firmware. System update, Oxygen Update or downloaded elsewhere. Make sure it is the Full OTA zip. Install it using the stock updater. DO NOT REBOOT. Open Magisk Manager, click yellow Install, Install again. Click Install to Inactive Slot(after OTA). Once done, now you may reboot. You may enable Modules, however ones like ROM Modules make sure they are compatible first.

It works with H2OS now:)

Thx a lot.

About the WiFi problem:

funny thing: i factory reset my phone (gm1913) with the 9.5.5 -> wifi working

after flashing STOCK recovery via fastboot (no twrp or anything) -> wifi stops woring

only way i got it to work again: flashed custom kernel via twrp

if you find any other fix, please let me know!
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] kyledowling:
As [MENTION=933657]schmeggy929[/MENTION] already said...

1) Disable all magisk modules and install the update with stock updater

2) Once it says to reboot DO NOT REBOOT and instead go

into magisk>install>install>install to inactive slot>yes

3) Once magisk says to reboot DO NOT REBOOT and install the twrp-installer.zip like a magisk module

4) Once step #3 is done you can finally reboot

Only if you have unlocked the bootloader and have the correct boot.img for the device.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] androidfreak11:
i still don't fully understand the instruction, as i can not find a step by step instruction

do i have to flash the recovery on boot_b?

do i have to flash the patched_boot on boot_a? or maybe it doesn't matter?

after flashing the patched_boot file i am now stuck in recovery bootloop unfortunately

thanks in advance!
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] bp328i:
I had the Chinese TWRP installed and everything was fine (Wi-Fi) I was like ok I will switch and flash this TWRP via the installer from the Chinese TWRP.

I flashed this installer and flashed the Magisk zip from the Chinese TWRP. When I rebooted I had no Wi-Fi (couldn't turn it on) and was no longer rooted. After trying a few different things I ended up flashing the Chinese TWRP again, once that TWRP was up I flashed the Magisk zip, now when I rebooted my Wi-Fi worked and I was rooted again.

After this I flashed this TWRP installer using Magisk Manager and installed it like I was flashing a module from my SD. Once it flashed I did not reboot but went back and flashed the Magisk zip the same way, like I was flashing a module from my SD. Now when I rebooted I had working Wi-Fi and root with this TWRP installed.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] androidfreak11:
via what installer do you mean?

you flashed it via fastboot flash boot twrp.img? and you got it working again with just installing a chinese twrp? (btw which one?)

i now get:

1.) i need to get wifi working

2.) install this twrp via magisk

3.) done

correct?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] bp328i:
via what installer do you mean?

In the first post under Downloads there is a installer zip that is flashed once you boot TWRP in order to keep TWRP.

you flashed it via fastboot flash boot twrp.img? and you got it working again with just installing a chinese twrp? (btw which one?)

No I did not flash it via fastboot, the Chinese TWRP is in the Guides, News, Discussions section. I believe the reason it (Wi-Fi) worked again is because the Chinese TWRP requires you to place an unmodified version of the boot.img from the software you're running in the folder with the flashing exe.

i now get:

1.) i need to get wifi working

2.) install this twrp via magisk Don't reboot and go back and flash the Magisk zip

3.) done
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] martinklaus:
I have Problem that i gett bootloop and the only fix is installing twrp on the old way with fastboot. But if i'm doing this wifi is not working. How i get a clean system without magisk and twrp that is booting?

If I have stock recovery and going to fastboot and flashing self patched boot.img the system is not booting.

I want to install clean boot.img and clean recovery.img and what is also needed?

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Paz9:
That's weird

I'd suggest backing up the keys

Mine have been deleted somehow.

/Vendor/firmware_mnt/widevine something

I'll relock and see if it goes back to L1

But on Reddit users have said the same, keys have been deleted, and re locking doesn't change to L1

One of the reasons I'll probably keep stock.

The only thing I can think of is using the flash all script

Booting without magisk

Stock and custom kernel

Something must trigger the deletion of the keys.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] mac796:
I was just curious when you open the play store hit settings scroll the bottom does your device say certified or not certified? If you're passing safety net clear the data of the play store reboot once and see if you go to l1. I'm not sure if that has anything to do with it but was just wondering.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Paz9:
I remember it said not certified, then I had to clear the cache and it showed certified
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] UnrealEgg:
Safe in what sense? Widevine L3 is worse than the default L1 on a locked bootloader.

So for now seems there are not important bugs.

After the donations i received in the last 2 days i decided to open a PayPal moneybox to buy a OnePlus 7 Pro for developing purpose.

Buying the oneplus 7 pro, I will be able to solve the problems and update the twrp in a very short time.

I will always keep the Fastboot ROMs updated and i will update the TOOL ALL IN ONE for the best support i can give you.

I usually made some guides about the phone and i will make them again for the OnePlus 7 Pro.

And i will never sell the OnePlus 7 Pro.

Maybe the development for OnePlus 7, OnePlus 7 Pro and OnePlus 7 Pro 5G will be unified so taking OnePlus 7 Pro will be good also for OnePlus 7 and OnePlus 7 Pro 5G development

Actually i already received 100 euros of private donations so the goal is reduced from 709 to 609.

All private donations i will received from now will be added in the moneybox as a goal reduction.

If you are not able to make a donation in the PayPal MoneyBox you can make a private donation and i will add it on the MoneyBox.

If in 1 month i will not reached up the amount to buy the OnePlus 7 Pro and i can't integrate to buy it, I will refund all the money.

OnePlus 7 Pro PayPal MoneyBox: https://www.paypal.com/pools/c/8fdio4Ro1s

If you are not able to make a donation for the MoneyBox and you want to partecipate use the classic donation link:
