[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
But you are converting from china to 12r then back to US genshin...I have never had thought to try if sim card worked on 2611 didn't cared...went rate to US genshin or cared about wifi
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:

[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Ok ..let me explain nicer..going from pje110..switch to 2611 ..307...do wipe in before phone reboot quick setup..no wifi...sim card nothing..just make sure OEM unlocked and USB enabled...next flash TWRP..do backup. Copy paste Halo500 US genshin...to TWRP folder.....flash ..wipe in TWRP...reboot setup and good to go
[OnePlus 12R / OnePlus Ace 3] VA4031:
ok not sure how but I tried deleting everything and setting up the folder again and it worked this time lol
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
But if you having problems flashing with bat.file...there is something wrong..only error you should have is modem

.I forgot to remove
[OnePlus 12R / OnePlus Ace 3] VA4031:
I've successfully completed the conversion process

thanks for the guide

i own pje110 model chinese genshin version, but cant do backup or computer things right now,

still on holyday vacation,, maybe later on workdays,,
[OnePlus 12R / OnePlus Ace 3] dansvel:
wow, is there any bugs yet?
[OnePlus 12R / OnePlus Ace 3] VA4031:
Haven't had any real issue so far.

Though there are a couple things that I've noticed but I think that's just how it is for the US version:

- The custom theme isn't as in-depth as the CN version:

+No theme for the home screen clock widget (the one on the lockscreen still works)

+Some stock apps such as dialer, sms, calendar are replaced with google's apps and don't have the custom icons

+Notification dots are red instead of purple.

+No custom themed keyboards

+Different version of game booster app without the theme and some features

-No theme store

-Dynamic icons don't work at all for calendar apps with the stock launcher (Stuck with their default icon instead of changing to the current date)

Also normal OTA update doesn't work and you will have to do it in a roundabout way.
[OnePlus 12R / OnePlus Ace 3] JustBucket:
Have you managed to install OTA update? I'm trying but still no luck ._.
[OnePlus 12R / OnePlus Ace 3] VA4031:
Yes, I downloaded the full OTA from oxygen updater and flashed it using local update in this app.

Then just go to fastboot and flash oplusstanvbk to restore network
[OnePlus 12R / OnePlus Ace 3] JustBucket:
this app shows toast "the dm verity is disable. please check fastboot unlock status" and refuses to flash local update. Did you also have this problem?
[OnePlus 12R / OnePlus Ace 3] VA4031:
I don't remember seeing that

Did you root or lock the bootloader after the conversion?
[OnePlus 12R / OnePlus Ace 3] JustBucket:
I didn't root and left bootloader unlocked
[OnePlus 12R / OnePlus Ace 3] VA4031:
Just updated mine to 701. Still haven't had any issue with it and looks like the the purple notification dots are back after the update somehow.
[OnePlus 12R / OnePlus Ace 3] dansvel:

So there's this screensaver thing that I assumed was just something that I accidentally turned on but couldn't find the settings for it at all so it might be a bug?

Found the solution after a bit of research and thought I should share it here in case anyone else needed it

Just download activity launcher, search for "Screen saver", open it and turn the thing off
[OnePlus 12R / OnePlus Ace 3] Ilya23232:
HI! I need help! I successful flash Oxygen from you post. But after restore Halo500 US Genshin backup from TWRP, system didn`t boot (just black screen, recovery available). I can reflash to simple Oxygen, but can`t get Keqing theme. I also try restore my TWRP backup ColorOS with same result - didn`t boot to system.
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
After you restore Us genshin...just go back in TWRP...don't reboot...need to do a regular wipe...then reboot
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
So restore Us genshin...go back in TWRP to where you see wipe ...do a wipe ( regular) not advance
[OnePlus 12R / OnePlus Ace 3] Ilya23232:
After flash and wipe I got error Failed to mount /system_ext /my_* (Invalid argument)
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
If you read in my how to...it will say you get those errors...don't worry just do a wipe and reboot
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Did it work out for you...?
[OnePlus 12R / OnePlus Ace 3] Ilya23232:
Yes, I read this. But after that system didn`t boot.

1. I restore backup and got this error.

2. Wipe (factory reset) and got error again.

3. System didn`t boot.
[OnePlus 12R / OnePlus Ace 3] Ilya23232:
Can you post img for fastboot flashing? I think something wrong with TWRP. Because only with fastboot flash I get working OS.
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
You still have fastboot..right...run bat.file again...after bat flashes...while waiting for device...unplug...do a wipe...let oxygen start up do a quick setup...flash TWRP.....see how that gets you
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Flash TWRP to both slots
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Here's the thing...you are in oxygen...there is no convert back to China yet...still working on it
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:

[OnePlus 12R / OnePlus Ace 3] Ilya23232:
I can`t use bat or EDL, because I`m Linux user ). I already have bootable Oxygen, but can`t restore Hallo500 US genshin TWRP backup. When I restore, system didn`t boot. After that I flash again previos step and get working OS (just Oxygen, not Genshin). I can`t understand, why TWRP restore didn`t work for me.

Why? fastboot flash from partitotion backup didn`t work?

Do I need to do unlock critical part of bootloader? I did simple unlock.
[OnePlus 12R / OnePlus Ace 3] dansvel:
is this tutorial also convert coloros to oxygenos?

my device just arive, it's a chinese genshin ace 3, and i plan to convert it to global genshin at this night,,

should I just convert it to oxygenos, or stay at coloros?

im downloading the requirement files right now
[OnePlus 12R / OnePlus Ace 3] VA4031:
Well it is a one way trip (as of now at least) so you should think carefully before the process

The main thing to consider is that pixelworks upscale+frame interpolation is only available in the chinese version.

You'll also lose some parts of the custom theme but that's less important (I found a workaround for that.)

In return you won't have to deal with half translated chinese bloatwares.
[OnePlus 12R / OnePlus Ace 3] dansvel:
the last paragraph is my main objectives, the others are not that important to me,, keeping my keqing is just a bonuses,

do i need to update my color os to last version before doing convert?
[OnePlus 12R / OnePlus Ace 3] VA4031:
Mine was on the latest OTA but I'm pretty sure it wasn't important. Also I think Canuck was looking for a backup copy of the stock un-updated ColorOS Genshin for the backward conversion so if you haven't updated then you probably should keep it that way
[OnePlus 12R / OnePlus Ace 3] dansvel:
i am really noob for customing an os phone, it really will be a big help if there is a clean tutorial, or better a video :v

but im gonna doin ut anyway, with this tread tutor,,

so

1. backup my chinese un-updated coloros for future research,,

2. convert my coloros chinese genshin, to oxygenos global genshin

3. maybe prepare for this https://community.oneplus.com/thread/1595803862105587712
[OnePlus 12R / OnePlus Ace 3] VA4031:
I'll write down all the steps that I did in a bit if that helps

i really appreciate that, it would be very helpful,,

thanks
[OnePlus 12R / OnePlus Ace 3] dansvel:
this is the version, i bought it second hand, so i dont know if this phone already doin update
[OnePlus 12R / OnePlus Ace 3] VA4031:
ok pretty sure 702 was the 2nd OTAs

on the bright side my phone was on that version before the conversion so at least I can confirm that it worked for me.

[OnePlus 12R / OnePlus Ace 3] dansvel:
my device not show up, what am i miss?
[OnePlus 12R / OnePlus Ace 3] VA4031:
Unfortunately I'm not sure how to troubleshoot these, hopefully it's not something that I've already installed before while playing around with my previous phone.

Is your phone currently in fastboot mode?

If it is maybe try unplug the phone and plug it back in then type the command again. And if that doesn't work then I guess you'll have to wait for someone more knowledgeable and just reboot the phone in the mean time
[OnePlus 12R / OnePlus Ace 3] dansvel:
yes, mine in fastboot mode, and i tried replug the cable, move to another usb port in my laptop,

do i need install some driver or something?
[OnePlus 12R / OnePlus Ace 3] VA4031:
that might be the case, I'm not sure which one though

edit: apparently you can keep the phone plugged in then go to optional updates in Window Updates to get the driver. I've never tried this method but seems like it worked for some people
[OnePlus 12R / OnePlus Ace 3] dansvel:
turn out its just the driver, i follow instruction online,

1. go to device manager

2. find a device with yellow warning sign, right click, update driver

3. seach automatically, search via windows update,

4. on system setting that show up, click update,

5. if it find any driver, go to optional update

6. checklist, download and install, the android driver,

7. wait till done,

8. check in device manager,

now, go to command and "fastboot devices" should show up your devices

now, let's go to next step
[OnePlus 12R / OnePlus Ace 3] dansvel:

[OnePlus 12R / OnePlus Ace 3] dansvel:
um,,, my phone got never ending boot loop on boot animation after this step,, :v

i manage to boot into bootloader again,,
[OnePlus 12R / OnePlus Ace 3] VA4031:
maybe the first boot was just slow, how long did you wait?

and did you touch those slot A slot B buttons on the twrp reboot screen? idk how that affects things but OP said not to change slot
[OnePlus 12R / OnePlus Ace 3] dansvel:
yeah, first boot is slow, i wait until the phone reboot, and reboot, and reboot again,,

i re-read the first tutor in this tread, and doin bot to slot a as my current slot is a,,

but the bootloop persist

hm,,
[OnePlus 12R / OnePlus Ace 3] dansvel:
im just copy my backup to computer via twrp mounting, as im waiting and wondering the solution,,

is it safe to just proccess to the next step?

damn, now im wondering, am i choosing the right slot on my first atempt,, what if i touch wrong button ,,
[OnePlus 12R / OnePlus Ace 3] VA4031:
you need to be able to boot to get some of the files though...

maybe try going back into twrp then do a normal wipe and see if that helps

honestly not sure what went wrong here
[OnePlus 12R / OnePlus Ace 3] dansvel:
im wondering if i can flash the stock rom from others people ace 3

my proccess is in copying the backup from twrp mounting, need an hour to copy to my hdd external, because my laptop out of space
[OnePlus 12R / OnePlus Ace 3] dansvel:
i dont know anymore,, the copy is done,,

i give up for now,, it alerady midnight here now,,

please, somebody help me,, :" )

edit : will something like this help? <Mod Edit> References to paid service links removed. Regards, Khusika - Moderator.
[OnePlus 12R / OnePlus Ace 3] PriPhaze:
If all you wanna do is recover your phone even if it is stock COS then just follow the Jookean EDL guide to restore your device but use the old method instead.

The link you posted should propbably work for you but ... hmm let me explain something that happend to my ACE 3.

I was testing Pixel OS rom so i converted my OCDT to NA and i totally forgot i had that flashed when i tried the EDL tool so it stopped right away at 3% and didn't continue no matter what, phone was just showing red letters and turning off in a minute.

Oneplus Unbrick Process

(you dont need a second computer like the old method says, just follow thisvideo instead)

So i had to use the old method using Proxifier and mtmproxy but i had to restore to NA version first (because that was the OCDT i had flashed) that way i was able to boot again to the fastbootd and flash my ocdt backup and once i finally had my COS OCDT flashed on the device i was able to use the EDL new method to restore COS .

EDIT: i didn't know tyour is the chinise version of genshin impact edition... so maybe my steps wont work for you? not sure but take that into consideration, mine is the normal ACE 3 1TB version.
[OnePlus 12R / OnePlus Ace 3] VA4031:
About the slot A/B thing

Basically the phone has an active slot and an inactive slot. When updating the new files will be installed to the inactive slot and the phone will switch over to that slot.

I think you might've accidentally switched to the slot with the older version which caused the bootloop.

Normally I would just try switching to the other slot to see if it works but I don't know if there's any device-specific issue with switching slots in this case.
[OnePlus 12R / OnePlus Ace 3] dansvel:
now that i'm in my job, i'll do whatever you suggest tonight,, thank you,,

like, flashing stock rom genshin, maybe,,

Your just stuck in bootloop... Dose of have oneplus logo then reboots...?
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
If so easy to get to fast boot...When phone cycles hold the power plus volume down..should get you to fastboot ...then run bat.file..get to oxygen
[OnePlus 12R / OnePlus Ace 3] VA4031:
The .bat file doesn't touch ocdt.img right?

In that case then flashing oxygen first then backup ocdt later might be an option

Need to get CN oplusstanvbk somewhere though
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
No it doesn't touch ocdt...but he should of have done a back up of everything first
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
I haven't had time to work out bugs converting Back to China genshin...cause there no edl file...I'm almost there...
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Rate now if you edl back...it goes to China 12r not... Not china genshin...
[OnePlus 12R / OnePlus Ace 3] VA4031:
Well the problem here is that they got stuck in bootloop before they could even root to make a backup of the ocdt
[OnePlus 12R / OnePlus Ace 3] dansvel:
yes, after oneplus animation logo, it reboot to the orange state and boot logo again

already doin backup, but when i restart, it stuck

yeah, im just at the beginning of fisrt step, right after install twrp and doin full backup,,

[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
I'm not on my computer...but put into fastboot...

I don't have command.. on phone

" Fastboot getvar current slot "

"Fastboot set_active a or b "

I don't have exact commands..but search you will find them..give that a try
[OnePlus 12R / OnePlus Ace 3] dansvel:
maybe i choose wrong slot, dont know,, everything so unfamiliar,, and im nervous in my first time last night,, :v

this night i'll try again,,
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Go fastboot...boot to recovery...should open trwp
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
In TWRP...go to restore...see if your backup is there
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
In fastboot...use up down volume will take you to recovery
[OnePlus 12R / OnePlus Ace 3] dansvel:
okay, im on my terminal
[OnePlus 12R / OnePlus Ace 3] VA4031:
it's 'fastboot getvar current-slot'

Edit: current slot is A and it didn't work so try switching to B I guess
[OnePlus 12R / OnePlus Ace 3] dansvel:
done,

set current slot, done

boot to twrp via colume button, done

normal wipe, done

so next will be reboot to slot a, right?

still bootloop,

ugh
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:

[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Reboot to slot b...
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Now the thing is...I don't know exactly what you done...cause if you where just to flash TWRP...do backup reboot phone should of just booted up...weird you just got boot logo...and that it...so try slot b
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
In my how to it say just to do that...cause you need to reboot phone ..put on computer...copy your back up.. to computer...then next your need your init_ boot.img to root...so you can get your original ocdt.img
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Edl would be your last step..cause rate now you have fastboot...recovery...just missing something...in what you done
[OnePlus 12R / OnePlus Ace 3] VA4031:
For now try switching to slot B, if it's still bootlooping then try restore the backup and wipe data
[OnePlus 12R / OnePlus Ace 3] VA4031:
ok I think I found an alternative method: you can backup ocdt and oplusstanvbk using TWRP but you'll have to be careful. If nothing goes wrong you should be able to continue to the next step

1. Boot into TWRP, change the language to english and go back to main screen

2. Select Advanced> File Manager

3. Select dev > block > by-name

4. Find and select 'ocdt' > Copy File

5. Select /sdcard (not /external_sd) and hit the blue button with a folder and a checkmark icon in the bottom corner

6. Swipe to confirm

7. Select Back, this should take you back to /dev/block/by-name

8. Select 'oplusstanvbk_a' > Copy file, the destination folder should still be in /sdcard so hit the blue button and swipe again to copy

9. Repeat for 'oplusstanvbk_b' (and 'persist', again idk what this one is for but people mentioned making a backup of it so you should do it just in case)

10. Now scroll to the top and select '(Up a level)' until you're back to the root folder '/' then go to /sdcard

11. For each of the files above, select file > chmod 755 > swipe to confirm to change the permissions so you can transfer it to your pc.

12. Transfer to pc and add '.img' to each files' names
[OnePlus 12R / OnePlus Ace 3] dansvel:
i boot to slot b,

it doesn't even get to the boot animation,

just the oneplus logo with orange state, then reboot on loop
[OnePlus 12R / OnePlus Ace 3] dansvel:
cant go to fastboot :(
[OnePlus 12R / OnePlus Ace 3] dansvel:
how to boot to recovery or fastboot using the volume an power
[OnePlus 12R / OnePlus Ace 3] dansvel:
ok

ay, volume down + power
[OnePlus 12R / OnePlus Ace 3] VA4031:
if you still have fastboot and TWRP then try the method I just posted. If you can get those files to your pc you should be good to continue to the conversion part
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Ok so a slot is where everything is on
[OnePlus 12R / OnePlus Ace 3] dansvel:
you mount it fisrt right? but mine like this
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
When it cycles through orange state hold power button and volume down...see if that works
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
You guys are step ahead of me..lol
[OnePlus 12R / OnePlus Ace 3] VA4031:
wait how did that happen

was everything still fine for all the previous steps?

maybe try rebooting TWRP I guess it's a bit weird sometimes
[OnePlus 12R / OnePlus Ace 3] dansvel:

[OnePlus 12R / OnePlus Ace 3] dansvel:
how mount sdcard
[OnePlus 12R / OnePlus Ace 3] VA4031:

[OnePlus 12R / OnePlus Ace 3] dansvel:
i manage to do this and doin copy to my pc
[OnePlus 12R / OnePlus Ace 3] dansvel:
dont know, but finish copy and add .img extension
[OnePlus 12R / OnePlus Ace 3] VA4031:
copy these to your adb folder and you should be able to continue the conversion, just use the ocdt and oplusstanvbk you have here instead of the one in the tutorial
[OnePlus 12R / OnePlus Ace 3] dansvel:
just confirm before continue,

how about magiks? and patch things?

am i skipp it?

so i just can go to next step?
[OnePlus 12R / OnePlus Ace 3] VA4031:

[OnePlus 12R / OnePlus Ace 3] dansvel:
ok, on running bat file, i got this error

for modem_a, in the fth folder is just modem

Or just delete my_bigball and replace it
