[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
First Things A must do : ( This what works for me several times )

Unlock bootloader.

Make sure computer can see phone in both Adb / fastboot

Read and ask question if you not sure.

There are other ways to get your files needed but ...this is a no brainer but will take sometime...

Great for new people trying to learn

This is for the beginners

This will be a long How To but I hope it helps

1. You need all your stock .img files ( so need a root backup or TRWP backup ) TWRP your best choice cause since no files released to root and you need your init_boot to root... This is for easy simple way

2. Once bootloader is unlocked and can see your phone in cmd with ADB / Fastboot (both) If not do not continue..need bootloader interface for both.

3. Now if all good Lets start... Commands for adb " adb devices " ... " adb reboot bootloader " ... " fastboot devices "

4. All good ... Now need to flash TWRP.img .. command for that... " fastboot flash recovery_a twrp.img "

" fastboot flash recovery_b twrp.img "

5. So to explain better.... in cmd type fastboot flash recovery space copy paste twrp.img and hit enter..All good..!

6. Once flashed and still in fastboot...use up/ down button go to recovery....TWRP will start up...

7. We need to change to your language in TWRP ...on right side..second from bottom ..click on that ..next you should see Globe on top right... click on that ... pick you language

8. Now you need to do a back up of your China Genshin. Hit backup in TWRP...click all the boxes ..include digest

9. Once done reboot phone from twrp. ( if on slot A reboot to A ..if on slot B reboot to slot B )

10. Unplug phone let boot up... Now uplug into computer and do the norm ... transfer files ... Open you phone on the computer ..you should now see a TRWP folder in your phone storage.. open that ... you should see a date with a # ...that is your backup... Copy past to computer...or USB... you really need these .

11. Now we can root... cause you have your init_boot. In your saved TWRP file.. open and look for init_boot... copy paste to desktop..

rename it " init_boot.img " copy paste to phone storage. Now download magisk to phone and install.

12. Root and Partitions Backup (ma.wanam.partions) will save all your stock files what are easy for you to see the img files. (dummy proof) ..LOL

13. To root ....we need to patch your stock init_boot... open magisk ..hit install ..next hit select and patch file...scroll down and you will see your stock init_boot...click on that and patch it...magisk will tell your where the patched img is saved...try and remember

14. Get you patched init_boot img file from your phone and save to desktop ..need to flash with fastboot.

15. Put phone into fastboot... open cmd...command " fastboot devices "...(must see phone)

16. " fastboot flash init_boot (patched init_boot.img) " if all good reboot phone open magisk you are now rooted

17. Now download Partitions Backup (ma.wanan.partitons) APK ..need to install with file manager

18. Need to give Partiton Backup root access... give file manager root access as well

19. Open partion Backup once installed... click on tool on top right...uncheck "compressed backup (tar.gz)..

make sure (img ) is checked... This will take some time and alot of space on your phone.

20. Now open phone on computer...you will see Partions backup folder....cut and copy to computer..you need the space

21. So now you will have all your stock img files Most importantly ... "ocdt" but you have them all..

Now onto second Part....LOL

That was fun ..lol

I hope I made it easy to understand

Now we want to convert you China Genshin to 12r Global CHP2611...307

No need to edl your phone to the CHP2611....307 file . I made a bat.file to flash it .... and you can flash with TWRP installed as your recovery...no biggy..it will take Unless you feel better flashing your stock recovery via fastboot from your Partions Backup

Lets begin

1. Download my bat.file ..It will have an empty FTH folder where you need to copy paste img files from the CHP2611..307

2. This is an CHP2611expot file ..so i will give you the img file to copy paste to the empty FTH folder.

3. Now in your saved stock Partition backup ...look for your stock (china) oplusstanvbk copy and replace it to the FTH folder

4. Put your phone into fastboot... Run bat.file... when finished flashing ..with no errors... when it in recovery do a wipe from recovery before it boots up on its own..and unplug from computer...if not you will have bootloop..

Explain better ..soon done flashing...it will say waiting for phone ...unplug and do a wipe...while still in recovery mode...let boot up and do a quick setup of phone.. Go to about phone...version...tap on Version # 7 times..do the norm...

5. Put into fastboot...flash TWRP to a slot and b slot...go to recovery and do a backup...Check mark everything same as before...save backup... same as before.... Now need to copy paste Halo500 US Genshin to the same twrp folder ..date with #

6. When doing a restore from Halo500 US Genshin you may get errors @ my_company etc...( dont worry go back in TRWP then do a wipe

(normal Not Advance )

7. Reboot phone and complete setup...put in Sim card... ( Do not Lock bootloader )

8. Put phone in fastboot ..cmd " fastboot flash ocdt ocdt.img " your saved original ocdt

I will Add all file
