[OnePlus 12R / OnePlus Ace 3] chaoscreater:
Hi all,

I'm thinking of buying a OnePlus Ace 3 and just doing a bit of research before I buy. I've read a few comments on this thread and I'm having trouble understanding a few things and wondering if someone can help me?

1. What are OCDT and oplusstanvbk? Are these partitions that can be backed up using TWRP?

2. I see in the first post that you can backup OCDT using this method:

but it doesn't mention how to backup oplusstanvbk?

3. Why does the first post say this?

I've always thought that firmware is completely unrelated to bootloader. On my Xiaomi phones, I can flash the firmware for different regions (China, Global, Europe, etc) and it doesn't affect the bootloader whatsoever. Isn't the bootloader just something that you can lock/unlock? Most people unlock the bootloader in order to root their device. Why would not having the original firmware affect your bootloader?

4. Xiaomi ROMs come with the firmware installed and so if you flashed a firmware for China and you want the Global firmware, you can either just flash the Global ROM, or flash the Global firmware package that is extracted from the Global ROM. Websites such as (https://xiaomifirmwareupdater.com/download/) makes this really easy to download ROM or firmware for your Xiaomi device. Do OnePlus ROMs not come with these firmwares?

5. What does it actually mean to convert Ace 3 to 12R? Is this simply converting from ColorOS to OxeygenOS?

6. Why do people want to convert their phones from ColorOS to OxygenOS? Is ColorOS really that bad? What's the difference?
[OnePlus 12R / OnePlus Ace 3] Advali:
1. Not sure but OCDT determines your region while oplusstanvbk is needed for the radio/signal. These 2 files must be from the same region in order for you to get a mobile signal. If your OCDT is from an Ace 3/ColorOS then you won't be able to use the Unbrick/Download/MSM tool from Oneplus and convert it to Global. You can only restore to what region your OCDT is assigned to. You can back up your OCDT via TWRP.

2. You can get a copy of oplusstanvbk from OFP or extracting it from the OTA file payload.bin

3. Without the original OCDT, assuming you did not back this up and replaced it with one from another region then you will permanently lose your bootloader.

4. Its more or less the same in oneplus. Without even changing the OCDT, you can directly flash the firmware files from global ROM via fastbootd and convert it to OOS but once an OTA is available, even if you sideload it you'll lose your signal unless you reflash the oplusstanvbk file and that means having the bootloader unlocked.

5. Pretty much yes.

6. It depends or depends on the person's needs but more or less its the convenience of having a set and forget setup. For the most part, the 2 OS are the same but with a couple of differences aside from the Chinese apps bloat and missing languages. But there are also google features missing in COS compared to OOS like using Android Auto out of the box, being able to use Assistant commands and some missing maps features etc. So if you're a user that depends on these apps/features then considering converting to OOS is already a given. And lastly, COS is somewhat tailor made for battery efficiency hence a lot of notifications from the playstore apps are delayed by default (but can be tweaked somehow).

Yes there are workarounds like for Auto and you can debloat almost all chinese apps and configure the COS to be similar with OOS including the notifications simply by configuring some battery settings and preventing certain apps from being optimized by the OS by default but a lot of users don't want to deal with that and just have a set and forget setup hence having the convenience of using OOS.

Personally I do appreciate some features native in COS that isn't in OOS plus having the latest update most of the time. For instance in my Ace 3, COS already has the April security update for a while now while my converted 12R is still on the Feb security update til now.
[OnePlus 12R / OnePlus Ace 3] chaoscreater:
Thanks for the explanation.

A bit confused here. I read your guide on how to convert from Ace 3 to 12R:

https://xdaforums.com/t/ace-3-to-12r-how-i-converted-my-oneplus-ace-3-to-12r.4663519/

I thought if you have the 12R OCDT, you can use it to convert Ace 3 to 12R?

Regarding #3 on permanently losing your bootloader, what do you mean by that specifically? Does that mean I can't use fastboot / fastbootd anymore? What if I already have TWRP installed and I boot into it and restore my OCDT from backup, will that fix this issue? OR, can't I just flash the ColorOS firmware/ROM to get the ODCT back?

Wait, are you saying you can simply flash firmware files to convert COS to OOS and it won't cause any issues with wifi or mobile signal, unless you install the OTA update? What if I just don't install the OTA update?
[OnePlus 12R / OnePlus Ace 3] Advali:
If you simply flash the OCDT file from other users or other 12R devices then yes you will lose your bootloader.

The reason why you'd want to backup and convert your OCDT first to global is to be able to lock your bootloader, have OTA and mobile signal available at the same time.

If you don't convert your OCDT from COS and just dirty flash the global OOS firmware, the conversion will still work but you would lose your mobile signal unless you flash the oplusstanvbk from COS. Now since your OCDT and oplusstanvbk is from COS, once you decide to lock your bootloader and install an OTA, you will lose your mobile signal again since the oplusstanvbk will be replaced by the global version from the OTA. In order to have a signal while on a locked bootloader while doing an OTA, OCDT and oplusstanvbk must be from the same region that's why we're converting your OCDT to global first so you dont have to flash the oplusstanvbk everytime there is an OTA. But if you're fine not installing any OTA or fine without replacing your OCDT and just unlocking the bootloader and flashing oplusstanvbk from COS everytime there is an OTA update then its up to you, cause that also works but its not a perfect conversion.

OCDT is specific per device and is not existing within any firmware files so if you don't have a backup and you decide to replace it with a 12R ocdt file you found somewhere then you'll never regain your bootloader.
[OnePlus 12R / OnePlus Ace 3] PriPhaze:
Sooo basically i can flash my ocdt and oplusstanvbk from COS while on OOS and i can even lock the bootloader but then forget about installing any other OTA in the near future correct?

Because if i do oplusstanvbk will be replaced with OOS oplusstanvbk and since my ocdt is from COS they no longer match.

By the way , in your guide you reccomend using an app to force LTE, do you have to do that step everytime you reboot the device? because it seems to chage back by itself to default.
[OnePlus 12R / OnePlus Ace 3] chaoscreater:
OK, a few more questions if you don't mind:

1. It sounds like you shouldn't use OCDT provided by other people and you should instead backup your device's OCDT and then convert it to global. But then why do people share the OCDT in the first place?

2. I still don't quite understand what you mean by "losing your bootloader". Are you saying that an unlocked bootloader becomes permanently locked? Or are you saying I can't use fastboot anymore (adb reboot bootloader)? Or are you saying my device is completely bricked and it won't boot at all, not even into TWRP?

3. You mentioned that I'll never regain my bootloader if I flash the OCDT from another user. Why is that? Can't I just boot into TWRP and restore my OCDT from backup, then my bootloader should work again?

4. What's the point of locking the bootloader? I've always kept the bootloader unlocked on all my rooted Android devices.

5. So say if I keep my OCDT unconverted and that I'm happy to flash the oplusstanvbk every time I have a new OTA for OOS. Say if my oplusstanvbk is extracted from OFP version 307. Would I be able to keep using this oplusstanvbk file, regardless of what OTA update I install for OOS? Or would I have to grab the latest OFP (e.g. 308), then extract and use the oplusstanvbk from it?

6. You mentioned earlier that Android Auto and some Google Maps features don't work (or don't work well) on COS. What are some examples? I'm used to using Xiaomi devices (which uses MIUI) and the China MIUI ROMs or even the custom ROM xiaomi.eu (which is built on top of China MIUI ROM) are able to use all Google apps without issues. I'm not even aware that apps can break on specific variants of ROMs. Aren't apps supposed to just work independently, regardless of the OS you're on, whether it's MIUI, ColorOS, OxygenOS, One UI, etc...?

7. Is the wifi & mobile signal issue specific to COS/OOS? Say if I flash LineageOS on my Ace 3, would I still run into issues if I don't have the correct oplusstanvbk that matches my OCDT?

As a side note, it seems there's not a lot of benefit to convert from COS to OOS, considering that even if you did it successfully, you won't get the mobile signal to work 100% as mentioned in your guide (https://xdaforums.com/t/ace-3-to-12r-how-i-converted-my-oneplus-ace-3-to-12r.4663519/).

Flash ocdt through fastboot and oplusstanvbk through fastbootd
[OnePlus 12R / OnePlus Ace 3] hsajeebal:
Hey can anyone help me?

I have a 10 pro which I want to change region. BL locked.

Trying EU with msm, it says device not match (as I have different region).

How to disable device check in msm or modify ofp file of eu to work for my device?

Do you still have the 10 pro?

Can you share the ocdt and other files?

Can anyone confirm if all the 10 pro are Oxygen os or not. If so, do I need the ocdt-persist files?
[OnePlus 12R / OnePlus Ace 3] kouzelnik3:
Yes, I still have it and rooted so I can provide the files. Which ones are needed except the ocdt and if you can tell me where I find each of them and also tell me the way to extract those? Or the classic dd command will work?
[OnePlus 12R / OnePlus Ace 3] hsajeebal:
My device's bootloader is locked. So I can't copy my ocdt.

Only the ocdt and persist files.

The DD command should work.
[OnePlus 12R / OnePlus Ace 3] Swe2:
What would happen if I keep my ocdt partition and just install the rom via EDL?
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
Need to keep ocdt file...just dont lock bootloader...with wrong ocdt..bootloader gone very hard to get back...for op10 and op12 gen 3

No crack tool for op10 pro and op12 ...need legit...wrong ocdt no flashie

This is a 12r..Ace 3 convert ..not 10 pro ...wrong section
[OnePlus 12R / OnePlus Ace 3] hsajeebal:
Where can I get oplusstanvbk?

Can I backup from my device?
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
You can get the stock oplusstanvbk from any edl file for op 10 china..the only way to back up is with root...or TWRP...but need bootloader unlocked

You might be able to try flashing with a oplus flash dev loader...may work may not
[OnePlus 12R / OnePlus Ace 3] PriPhaze:
You don't need root to get the oplusstanvbk , i got it from the payload of the latest update of COS and using FastbootEnhance; i guess you could use any other payload dumper and still manage to get it.

The one you need root no matter what is the ocdt which is unique of your device.
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
You can get the stock oplusstanvbk from any edl file for op 10 china..

Root would be for ocdt...while your root get all files...good to have
[OnePlus 12R / OnePlus Ace 3] mr.mgmg:
hi

i have problem with persist partition and i didn't backup , please can anyone share persist file

please you can share persist file with me
[OnePlus 12R / OnePlus Ace 3] PriPhaze:
i know, all im saying is that root is not nnecesary for oplusstanvbk
[OnePlus 12R / OnePlus Ace 3] hope963:
Hello. Could someone send me a conversion file, ColorOS to OxygenOS? Thank you very much in advance and best regards.
[OnePlus 12R / OnePlus Ace 3] zyhhzy:
Hello, I'm a newbie and I'm trying to install OOS.505 for my ACE3 now!

[OnePlus 12R / OnePlus Ace 3] zyhhzy:
OK,Thank you a lot，But I don't really understand what Flashall is.
[OnePlus 12R / OnePlus Ace 3] zyhhzy:
And, I don't need to backup my ocdt before flashall?
[OnePlus 12R / OnePlus Ace 3] zyhhzy:
Thank you! It works，I run flash_all and clear the data ，now I have OOS(India) On my ACE3
[OnePlus 12R / OnePlus Ace 3] brunomtr5:
Hello, is it possible to make a file like the one

Hello, is it possible to make one pack like that but with global or european version?
[OnePlus 12R / OnePlus Ace 3] zzzzwdk4444zzzz:
Hi im having oneplus ace 3 can i use this method to convert to oxygenos?

Edit: i got this error Failed to get flash sign from server, how can i fix it?
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
yes
[OnePlus 12R / OnePlus Ace 3] Canuck Knarf:
All you need is all img files from export file...or edl file...flash via bat.file
[OnePlus 12R / OnePlus Ace 3] zyhhzy:
It's india version
[OnePlus 12R / OnePlus Ace 3] darkrevlis01:
I suppose that with this rom it is not possible to block the bootloader either. I am right?
[OnePlus 12R / OnePlus Ace 3] Jookean:
Usually it is possible, try it

But remember that you do not do OTA, otherwise you will lose mobile signal.

But bricking or loss of signal can be fixed by running msm tools with colorOS rom

I have successfully convert to oxygenos global with old method. How can i update to latest version? Im using chinese oplusstanvbk and ocdt since global oplusstanvbk and ocdt signal is very unstable.
[OnePlus 12R / OnePlus Ace 3] PriPhaze:
just update as usual and re flash oplusstanvbk once the update has completed.
[OnePlus 12R / OnePlus Ace 3] zzzzwdk4444zzzz:
Do i need to grab oplusstanvbk from latest chinese firmware or old one is good?
[OnePlus 12R / OnePlus Ace 3] PriPhaze:
tbh not sure about that, i think they work the same no matter the version but in my case i grabbed the latest
[OnePlus 12R / OnePlus Ace 3] psychemisha:
Does this new method works on the original op11
[OnePlus 12R / OnePlus Ace 3] Jookean:
Of course it supports it already, just overwrite the firehose.
[OnePlus 12R / OnePlus Ace 3] iKOOLCORE:
Thanks for providing the files. Last night, attempting an OTA update with the full package resulted in signal loss. I 0 flashed the oplusstanvbk.img file you provided under the bootloader and confirm signal restoration. Everything should be back to normal now. My Chinese version ACE3 (which has been flashed with the US version CPH2611, globally known as OnePlus 12R) is back with OxygenOS 14.0 now.

Ok, with this process. I could flash my "12R" (Ace 3 original ocdt and original oplusstanvbk) with any custom rom like Lineage or Pixel Experience? Thanks in advance!
[OnePlus 12R / OnePlus Ace 3] etajv100:
Could you explain please?

do i need to flash modified ocdt?

Have you solved the problem yet? , I also have the same problem
[OnePlus 12R / OnePlus Ace 3] Diangucmau:
Someone please help me, now the device is bricked
[OnePlus 12R / OnePlus Ace 3] VA4031:
ok admittedly I haven't done this EDL stuff myself but why does your device show up as a Oneplus 10 pro?

and why do you have a folder named ACE2 PRO?

Hate to ask the obvious but are you sure that you have the right phone for this?
[OnePlus 12R / OnePlus Ace 3] zzzzwdk4444zzzz:
The problem is i used new method for convert which does not work. Then i flashed Jookean global zip which brick my device. Then i edl flash oxygen with old method to fix and convert. Remember to backup original ocdt.
[OnePlus 12R / OnePlus Ace 3] ÁngelR97:
My cuestion is: if i make a new "12r" with this process, it could be possible to install other custom roms that are designed to 12r? Or with that flashall of Jookean ACE 3 still appearing as ACE 3. Greetings!
[OnePlus 12R / OnePlus Ace 3] ÁngelR97:
Could you be more specific? How it works? I´m pretty noob and dont understand what i need to do. Open bootlader and then open cmd windows and prompt "fastboot flashall OP12R Global.zip"? Thanks in advance!
[OnePlus 12R / OnePlus Ace 3] Diangucmau:
The old method is to use flashtool like oneplus 11, right? Please explain clearly to me Even when I just unlocked the bootloader, I couldn't get back into fastboot
[OnePlus 12R / OnePlus Ace 3] Diangucmau:
it doesn't matter, it's flashtool crack for 8gen2, I use it to run for ace 2 pro and 11, ace3 doesn't work 😐
[OnePlus 12R / OnePlus Ace 3] zzzzwdk4444zzzz:
I did exactly like jookean instruct with old method, follow the instruct video in old thread(single pc) and replace file before click flash. Don't care about fastboot we are using edl mode. Use hardware combination to get in edl mode. If you just want to get back to coloros then you can try new method.
[OnePlus 12R / OnePlus Ace 3] Diangucmau:
Please check your private messages, I want your telegram, can you ultraview it for me?
[OnePlus 12R / OnePlus Ace 3] etajv100:
Ok i flashed his file and let me tell you it's the singular perfect method i have tried, before i did flash his file i edl back to stock 301, then did as he said, i didnt flash modified or converted ocdt, just ran his file and my phone is finally converted to OxygenOS, and yes the phone is being recognized as 12R so i think you could try flash Pixelos after using his file, but for now i'm satisfied with my phone as i can finally have the actual Oneplus Experience with Oxygen rather than the Chinese Ace 3 and on a positive note, i had 0 craches 0 reboots i think he changed something so the 4G is selected by default, this is as vanilla as it gets going from Ace 3 To 12R, the only downside i noticed is battery there's a little bit more drain compared to stock ColorOS but it's still very negligible, one weird thing the ColorOS was missing is the google quick share, now it is availble... weird how important basic things seem when you don't have them...

This should have it's own Post.

one thing i don't know is if the system is modified to work with Stock Ace 3 OCDT or what...
[OnePlus 12R / OnePlus Ace 3] ÁngelR97:
How have to run that file? Could you show me exact steps? Thank you!
[OnePlus 12R / OnePlus Ace 3] etajv100:
if you are on stock ace 3 rom unlock bootloader, turn on the phone with power + volume down, once you're at bootloader make sure the phone is detected by running fastboot devices, if your phone gets recognized run the file "Flash_All.bat" make sure to read the cmd windows to follow the steps as at the end the script will ask you to select english then wipe data, reboot and voila!
[OnePlus 12R / OnePlus Ace 3] Diangucmau:
okay, today I unbrick my Ace 3 device myself, I can simply say that when flashing MSM using EDL mode, the owner did not clearly mention which msm EDL file will be run, for file prog_firehose_ddr.elf in article #1, we will overwrite the file CPH2609GDPR_11_14.0.0.307EX01_2024012713410000.zip , someone should not try to flash the file PJE110domestic_11_14.0.0 .317CN01_2024012904340 000.zip does nothing, it won't work!
[OnePlus 12R / OnePlus Ace 3] PriPhaze:
It works too

It's just that you had a different ocdt flashed and not stock cos ocdt that's why it was failing.
[OnePlus 12R / OnePlus Ace 3] zyhhzy:
you should unlock the bootloader and unpacke the Global.zip then, make backup of your ocdt.img, then make your phone in bootloader method, run the Flash_all.bat in the Global.zip with CMD（you must have the fastboot.exe firstly）.

Wanted to flash mine to 12r rom(OOS) from coloros but seems that current 12r didnt have pixelwork x7 chip for enhanced gaming experience 😪
[OnePlus 12R / OnePlus Ace 3] rhynero:
I am in bootloop, so the powered by android screen repeatedly comes on and then off and also vibrates.

When it is in this state, the only way I got it to stop was to hold both volume buttons when plugged in and then it shows up as COM3 in device manager but doesn't show up in the tool. I unplugged and replugged the cable while still holding the two buttons but it doesn't show up. Any ideas?

Context: ACE3 Genshin version, I converted it to US OOS and then US genshin by following Canuck, then I tried to lock bootloader and then it is boot looping

Now I have the red text saying that the download process was incomplete. The flashing tool said it was mismatched. So instead of using the US OFP packages I use CN package?
[OnePlus 12R / OnePlus Ace 3] ColdCawfee:
exact same issue, no idea what to do. Any help would be greatly appreciated
[OnePlus 12R / OnePlus Ace 3] rhynero:
Ok so I spent some more time, I had to use the CN package and to solve the not recognised thing I just had to try multiple times force shut down by holding the power and volume up button and then when it turned off immediately holding the volume up and down button.

Then you will hear the alert sound on windows and it might not be showing up on the tool the first time, but keep trying with the flashing already started and the nv on.
[OnePlus 12R / OnePlus Ace 3] ColdCawfee:
Some help would be amazing rn

I can get windows to detect my phone but are you using the old method with the proxy thing? I do not have any Linux/Mac so I might be out of luck
[OnePlus 12R / OnePlus Ace 3] rhynero:
Use all of the resources in the description of this video and follow it, up to when you launch the Flash tool, then follow Jookean's steps. I had some difficulty with setting up mitm but if you follow the video hopefully you will be fine. Good luck, and I'm here to help if I can
