Accidentally removed OS in OP3.

Hi all,
While trying to install custom mod i accidentally deleted my original rom as well as the custom rom from my phone. I can access twrp fast boot but while trying to install zip file its missing from phone. Any way to install any custom rom at this point?
Update : Restarted my phone ( well powered off coz of low battery) . When i charged and switched it on , twrp is not there . Instead when i go to recovery mode , the original one plus recovery mode is appearing.

Sideloading is the easiest option.
Boot into TWRP, find ADB Sideload mode (I think it's under "Advanced", not sure), connect phone to PC via USB cable and flash ROM directly from PC with "adb sideload rom-name" command.
This is a very short version, if you need me to explain anything in depth just say it

Sorry for late reply.
So, first things first, make sure you have working adb/fastboot on your PC (you can get it >>HERE<< if you need it; select Y for all options).
- download latest TWRP recovery >>HERE<<
- download a ROM of your choice
- in case you go for a custom ROM you'll probably also need latest firmware (CLICK), Gapps (CLICK) and possibly Magisk (CLICK)
- open command prompt in folder where you've put all downloaded files - hold Shift and right click in that folder > open command window here.
- boot phone into fastboot mode and connect it to PC
- type fastboot devices in cmd to see if the phone is properly recognized (should say something like "device #serial-number" IIRC)
- flash TWRP by typing fastboot flash recovery recovery-name.img
- reboot device into recovery mode. Fastboot generally doesn't support rebooting into recovery, but our phone makes it easy with that 5 second timeout on boot. Type fastboot reboot and as soon as it displays that warning screen press a volume button and then scroll to recovery with volumpe up/down.
You should be booted into TWRP now. Let's continue to flashing a ROM.
Assuming you're going for a custom ROM, start with firmware:
- select "Advanced" in TWRP
- select "ADB Sideload"
- swipe to start sideload
- type adb devices in cmd - it should recognize that the device is in sideload mode
- type adb sideload firmware.zip and wait for it to finish
- go back to main TWRP screen and repeat the steps to get into sideload mode
- type adb sideload rom-filename.zip
- repeat to flash Gapps and Magisk
If you chose to flash stock ROM rather than custom then you can skip firmware and Gapps and flash just the ROM (and possibly magisk, that's up to you).
Done! Now you can boot into system.

Piece of advice :
If there comes any problem with this unlock process, NEVER try to unlock by official unlock tool, as you will not be able to install custom recovery and finally end up in an unlocked bootloader device with no warranty and no custom recovery to proceed further!!!
in such cases fix the communication between phone and pc, instead of directly jumping to official tool​

Wow..
Anyone try this??

what is the firmware version that is being used in this Indian root image? mine start with ww_xxxxx.....

Will the unofficial way of unlocking void warranty?

Yes. Warranty will be void. But there is always a possibility of relocking bootloader to obtain warranty.

Was someone able to root successfully?

Yes. I confirm this works.

Which method did u use
Did u unlocked the bootloader and then flashed masgisk via twrp or via patched boot image method.

Got it working the problem is with adb it was installed and then I reinstalled it as given in steps, which might have broken the adb so if I performed the steps in ubuntu and everything worked perfectly. I am attaching the error images. If anyone else getting issue try uninstalling adb and drivers and then reinstalling adb and drivers.

Official way?
will there be official way?

There is official method available on asus support page for max pro m2.
Note: doing the official way there is no chance for relocking the bootloader and claiming warranty

Want to use Sultan kernel, having flashing issues

Hey guys. Just upgraded to the android 10 October image via the adb flash-all command. Magisk rooted via adb and everything is going great. Want to install Sultan's ported kernel for Android 10. Used adb to flash twrp image and flashed the kernel zip via twrp but it keeps saying it can't mount /system and /vendor upon finishing. Upon rebooting I get stuck at the google G load screen. Have to redo flash-all and instal magisk via adb all over to get back to normal. Anyone have this problem or could offer some help? Would be great.

As long as the kernel finishes the install it's fine. The mounting errors don't matter if it finishes. The mounting errors are just a bug with Android 10. Everything I flash has those errors after it, but I am good. I am on Oct. with Magisk 20 and Sultan kernel.

So the way I'm seeing it is flash the twrp image file, flash the kernel, reboot. Then adb fastboot to bootloader and reflash patched magisk boot.img?

Do this:
Setup:
1. Download latest platform tools for your OS
2. Download latest factory image for Pixel 2 XL
3. Download twrp.img and twrp.zip
4. Download the kernel.zip you want
5. Download magisk.zip version 20
(Keep in mind those aren't the actual filenames, I am just shortening them; plus you will want to rename them for easier flashing)
Install:
1. Boot phone to bootloader.
2. Extract factory image into the platform tools folder
3. Run flash-all script
4. After done reboot back to bootloader (dont do the phone setup)
5. Now remove the factory image from platform tools (or just extract a clean platform tools folder)
6. Place twrp.img, twrp.zip, kernel.zip and magisk.zip into the platform tools folder (rename the files to make it easier to type them out when flashing with computer adb)
7. Run: fastboot boot twrp.img (or whatever you named it)
8. When in twrp, go to settings and turn off "screen timeout" there is a bug
9. Go to advanced then "adb sideload"
10. In your computer terminal type: adb sideload twrp.zip
11. Then run: adb sideload kernel.zip
12. Then run: adb sideload magisk.zip
13. Reboot to system
Should be good! Using sideload allows you to pass files from your computer to your phone, it makes it easy. If adb sideload is "hanging" or "freezing" (you should see a kinda progress bar with it's working) then reboot twrp.img and try a different USB port. There is a glitch when it hangs, where when you remove the USB cable the phone goes black; just hold power + volume down for about 10 seconds and it will boot back to bootloader.

The Ultimate guide to flashing CRDROID A12 for OnePlus 8 Pro

I have written this comprehensive step by step guide on how to flash CRDROID android 12 ROM for the OnePlus 8 Pro. The original instructions do not cover enough detail.
Ensure you have all applicable drivers installed onto your computer by following this video tutorial:
Reset your phone through using this MSM tool to return to Oxygen OS 11: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4084953/
Install the application to your windows device
Choose the international version
Turn off the phone. Hold BOTH the VOLUME UP AND DOWN at the same time and plug into the computer. The application will now recognise the phone where you can do a factory reset to Oxygen OS 11.
Install Oxygen OS11 on BOTH Slots:
install the latest Oxygen OS 11 from the OnePlus website, as a local upgrade: https://www.oneplus.com/uk/support/softwareupgrade/details?code=PM1587123976
If the official link goes down, find the file from here: https://forum.xda-developers.com/t/oneplus-8-pro-rom-ota-oxygen-os-repo-of-oxygen-os-builds.4084315/
Restore to oos 11 using msm -> unlock bootloader -> download latest oos 11 -> transfer to phone -> then system update via local upgrade -> reboot and update via local upgrade + reboot again
Connect to the internet
Click multiple times on the build number after updating to enable developer options
Enable options of OEM unlocking and USB debugging
Once you press usb debugging, connect your device to your pc -> a window will pop up on your device -> press always allow from device. You need to do this for usb debugging to work.
Enter fastboot mode by pressing and holding the Power button to bring up the Power menu and select 'Power Off'. Once you have done that: Press and hold the Volume Up', 'Volume Down', and 'Power' keys together to enter Fastboot Mode.
Unlock the OEM:
Once you're in fastboot mode after pressing oem unlock + usb debugging toggles -> type 'fastboot oem unlock' -> press volume up + power for yes and the device will reboot.
To install the RECOVERY
Download the file named like this: crDroidAndroid-12.0-XXXXXXXX-instantnoodlep-v8.X.zip and recovery from the officaial website:
https://crdroid.net/instantnoodlep/8
put it in the same folder where your adb files are
Open CMD from the adb tools folder on your computer, and type 'fastboot devices'.
if working properly, you will see your device
Type 'fastboot flash recovery recovery.img'
Reboot to recovery
To install custom ROM from recovery
choose "Factory reset"
choose "Apply update"
adb sideload "crDroidAndroid-12.0-XXXXXXXX-instantnoodlep-v8.X.zip"
reboot recovery
choose "Apply update"
Install the correct GAPPS
You're supposed to use nikgapps-SL basic and Nikgapps-SL addons (if needed to restore from playstore backup. Use pixel wizard setup for this.) Good examples of addons you should use will be attached.
For Nikagpps-SL: https://sourceforge.net/projects/nikgapps/files/Releases/NikGapps-SL/09-Jul-2022/ and for Nikagpps-SL addons: https://sourceforge.net/projects/nikgapps/files/Releases/Addons-SL/09-Jul-2022/
adb sideload "gapps"
choose "Apply update"
adb sideload addons
Do the "Apply Update" and sideload each addon
choose "Apply update"
To root the phone:
adb sideload magisk.zip (Change magisk.apk to magisk.zip)
reboot to system
Please comment below if this has helped!

Thank you. By carefully following your guide I was able to unbrick my 8 pro and finally install a non-oxygenos android 12 build. Other guides did not work for me.

I don't see where recovery.img is on crdroid website?

This guide helped me get crdroid running, however I'm having severe issues getting ANY google apps to run. I sideloaded the ones you recommended, but play store wasn't installed, play services wasn't installed. After I downlaoded those apks it did nothing and they dont work. My biggest problem is I can't link my google account to my phone in the settings, I don't see 'Accounts' anywhere in the settings; Which has all my contacts. So at first I thought it was a success, now my phone is literally useless to me until I get my account linked to my phone which seems impossible with crdroid.

How can we do this with TWRP install? If not, why not? Why do all the instructions I see for crDroid use ADB sideload instead of just 'install zip' like every other custom ROM? Also, how do we install Magisk? The usual way via TWRP?

Question Any guide how to root latest OnePlus 9RT build MT2111_11_C.05?

I was wondering how to root the 9rt on android 12 in hopes of activating volte and unlimited google photos, can anybody help please? Thank you.

Above post just echoed my thoughts. Thank you.
Eagerly waiting for TWRP recovery for this and a good Custom OS (CrDroid, Pixel Experience, AOSPxtended, etc)

TWRP is not a requirement to install Magisk. Magisk can be installed via fastboot.
1. Install drivers, adb and fastboot to the PC.
2. Install latest Magisk apk to the phone.
3. Download boot.img for your version, place to the phone memory.
4. Open Magisk, choose "Install" -> "Select and Patch a File", select boot.img file from p.2, press "Let's go"
5. After it's finished, find patched boot img in Dowloads directory, named something like "magisk-patched*.img". Download it to PC.
6. For the Windows PC open command prompt cmd. For Mac and Linux open terminal.
7. Reboot the phone to bootloader. I.e. with adb reboot bootloader command or by rebooting with pressed Vol Down button.
7. Type 'fastboot flash boot <path to magisk_patched*.img>'
8. Reboot to the system
