[OnePlus 12] farhansaeeddnp3021:

when i only power its going to stuck on logo and after 10 sec its goes to EDL.

after holding volum down + power button i am still able to go fastboot mode.
[OnePlus 12] flandolf:
I see you are trying to flash ColorOS using Canuck's script, did it work? Or are you still bricked.

You didn't provide logs for FTH flashing so I'm not sure what's up with that maybe you didn't flash those images aswell?
[OnePlus 12] Canuck Knarf:
Do you mean lock bootloader...?
[OnePlus 12] Canuck Knarf:
I will..but its the img files they are big
[OnePlus 12] Canuck Knarf:
Im working on something to test...need you to try...see if it helps..I will upload to google drive but has two img files..its big...but this may help...?
[OnePlus 12] Alex 4:
Yes. Is it possible to block bootloader. After flashing on oxygen?
[OnePlus 12] Canuck Knarf:
Have you Guys got this

internet downloader...works great

[OnePlus 12] Canuck Knarf:
Ok you not using my new bat file..cause I added that in the script...and it works
[OnePlus 12] Canuck Knarf:
You need to replace the old Flash_All_SuperZip

with this one ....read the How to....it rate in it

Next you need to down these files " what are my new bat file "

I have added to Bat file:

: fastboot w "rate in the beginning "

: flashing img files from the " FTH" folder

: reboot phone to " fastboot unlock or lock "

: use volume Up / Down ....Up to yourself

Thanks, I'm using the download manager in firefox and the MediaFire links just stop at random times.

I'm uploading the OP12_CONVERT_US_CPH2583export_11_14.0.0.232.rar to Gofile now

I'll post the link here when it's done.
[OnePlus 12] Canuck Knarf:
How long to upload...mine say 2hrs...Its big though ( 2 img folders and bat file etc)
[OnePlus 12] Canuck Knarf:
I wonder if dropbox better...?
[OnePlus 12] Isavar:
I think the same, I understand that the bands are in the modem which is hardware and depending on the area the modem changes and the bands too
[OnePlus 12] clsA:
yeah 2 hrs plus .. first upload failed at 64%

I also tried my old Androidfilehost account, that service has got to hell even the small files failed there
[OnePlus 12] Canuck Knarf:
I might try Drop box ..?
[OnePlus 12] E-61:
I'm not sure if the hardware is different. Either way there is nothing we can do nowadays. Unlocking bands was a thing in the past I remember it was possible to do that with some phones. But for that you needed to dive in deeper than just flashing different roms or rooting your phone.
[OnePlus 12] AlecTR:
Appreciate the guide! I am really wanting to pick up a Chinese version of the OP12 tomorrow seeing the conversion from color to oxygen os is now possible.

Just wanting to confirm if fingerprint, Google pay, NFC are all functional after the conversion?

You mean to lock the bootloader again? Yes it is and shown in the other OxygenOS Flash Guides.
[OnePlus 12] Naraa:
it's possible
[OnePlus 12] Ray_:
Hi, I locked my bootloader after the process, and my phone is bricked xD tho it was working fine before locking the bl.

it says " the current image{boot/recovery} have been destroyed and can not boot. please flash the correct image or contact customer service to fix it"

now I am not able to get into fastboot using vol- and power button.

it allows me to get into Qualcom port 9008, and I have the EDL cable, anyway to unbrick it ?

Thanks in advance
[OnePlus 12] Canuck Knarf:
I will download and see if corrupted...all good on my computer
[OnePlus 12] richard_li:
why the flash back to color OS file so huge ? almost 17.35Gb.

But only 7Gb for other files convert to Global/India
[OnePlus 12] richard_li:
yes, no problem for me to re-lock the bootloader
[OnePlus 12] vegetaleb:
This guide can be used if we want to go from Indian FW to EU one? Or it's only Chinese to other FW?
[OnePlus 12] dalet11:
when switching from EU to GLO, is data wipe really required? basically they are the same with minor changes and some hardcoded properties changes.
[OnePlus 12] Maheshwara:
Can anybody tell me if it's possible to convert between firmwares by using Local Updater with UNLOCKED bootloader? Download zip with Oxygen Updater or from here and then, flash it by Local Updater without needing a PC for flashing... ?
[OnePlus 12] JEANRIVERA:
not possible this way
[OnePlus 12] i23u8:
how can i convert back from global to coloros? i tried the converting twice and it always gives me black screen after the format data and reboot.

i tried installing pbrp and it looks like userdata is showing size 0 or inaccessible.
[OnePlus 12] xmh+xda:
--- removed ---
[OnePlus 12] Bastin05:
I understand that it is the Chinese version, but with the global ROM. This causes me a doubt, when changing the ROM, will the device be able to update to the next version of Android and subsequent ones as a global version phone would normally do?

I know that you will receive Oxigen OS software updates via OTA, but my question in this case is about Android version updates. In other words, will this Chinese version device with a global ROM receive Android 15 when it is finally available?
[OnePlus 12] varunvijay89:
Hi,

[OnePlus 12] Canuck Knarf:
Yeah pretty much
[OnePlus 12] rayvnce:
I still can't flash to ColorOS, not sure why. I've tried it five times already, but it failed at my stock. Now, I'm going back to the global ROM. Anyways, thanks a lot for making this happen. This will be my last flash, and I'm sticking to OxygenOS. I'm better off waiting for OnePlus to fix my problem (No ACR). 😅
[OnePlus 12] Canuck Knarf:
Don't give up...lol...when I get home from work...I want to try to download something and flash...it big...has two img files plus bat ..etc I changed just for this...ok

Can you fix the links? Both 6.9GB "FTH.Gobal" files flash as CPH2573... but the FTH.India files are 6.1GB?
[OnePlus 12] Jingye Wang:
Thank you, this works fine on my Chinese version of OP12. Is there an EU version available here? After flashing the GLO file, it shows CPH2573, which I believe is the Indian version. The US version file is 2583 and works fine. I remember that for the EU version, system updates can be selected from local files, right?
[OnePlus 12] Canuck Knarf:
I will Just got to remember to do and Have time..But i will fix
[OnePlus 12] Canuck Knarf:
Hey guys Use the Drop box files ...should be right
[OnePlus 12] bdvince:
It's not.. Both the dropbox and mediafire links are 6.9GB. I flashed the "FTH.Gobal" from dropbox and now I'm on CPH2573.

I downloaded your OP12_CONVERT_GLOBAL_CPH2583CPH2581GDPR_11_14.0.0.232 (which has both CPH2583 and CPH2581 in the same filename) and zipped the FTH folder and it's 6.4GB.

The files and naming is all mixed up, we need to start over fresh lol.
[OnePlus 12] keysillage:
yes, the "FTH.Gobal" from dropbox and now I'm on CPH2573. it maybe the file got a wrong name and mess up
[OnePlus 12] rayvnce:
tried converting back to ColorOS. not sure since i saw 2 failed commands, but it booted to ColorOS. 👍 still my bootloader is unlock. dunno maybe this has region lock or not so not gonna lock it. 😅
[OnePlus 12] gogitossj:
Does OTA work for Oxygen?
[OnePlus 12] timebandi:
Any way to confirm it's the right one before flashing? I going to start this adventure when I'm at work and don't want to encounter strange problems :)
[OnePlus 12] timebandi:
Does someone have that EU instead of Global? 2583. Want 2581.
[OnePlus 12] hoang6491:
Today I

Yes. Got update on my converted OP 12 - India rom
[OnePlus 12] Vlncent89:
As I understand it, there is no purely European firmware yet, you have to wait and then put it in the FTH folder and flash it.
[OnePlus 12] gogitossj:
So you have Chinese OP12, unlocked bootloader and install the Indian ColorOS. Then you can OTA officially like a global OP12?

Is everything working correctly? GPay, banking, .... notification especially (I assume you are from VN as am I).

Also why Indian and not US version?
[OnePlus 12] hoang6491:
Yeah, right. can ota update, same as global OP12 I think.

Working fine without any issue because it has full GG services. I always use India version instead of US because it has more compatible LTE/5G bands configs.
[OnePlus 12] gogitossj:
Nice. Did you need to relock the nootloader for GPay to work?
[OnePlus 12] rayvnce:
does oneplus 12 india rom has call recording? dayum, it seems all network bands from india rom is compatible to my country region network band. i'm planning to switch if ever that feature ACR is available.
[OnePlus 12] bdvince:
Call recording is dictated by region setting set by MCC, not rom or apk. Even if you install ODialer on Indian rom it would not work by default. Here I have Recording enabled in the US and on NA firmware of OP11.

Once I get the region lock on my OP12 sorted I will try to enable it.
[OnePlus 12] rayvnce:
its okay, just converted to india rom and indeed call record does work using odialer. thank god, i might stay with India rom for now.
[OnePlus 12] hoang6491:
Yes sure need relock bootloader after all. GG pay, McDonald's (god, why it need to check) .. is working fine.

Till now Odialer auto recording feature not working. Pls consider
[OnePlus 12] rayvnce:
it worked. i just got flashed to india rom and have tried calling. it did record my calls. odialer also available in playstore when using indian rom.
[OnePlus 12] hoang6491:
Yeah confirmed work on India rom with Odialer. Just double check
[OnePlus 12] bdvince:
In Vietnam call recording should be supported by MCC already by default with just ODialer. Which rom were you having issues with?

@rayvnce what is your carrier also?
[OnePlus 12] rayvnce:
i'm having problem with CPH2581 (global/EU rom). i can't install Odialer as it is passive on playstore and default google phone dialer doesn't have call record setting even when i install an Odialer Apk from apkpure or even extracted out and install a Odialer APK from PJD110 (china rom). still no call record setting to be found.

when i switched to CPH2573 (Indian rom), now i can install Odialer from playstore natively and can also enable auto call recording.

Thanks

-------------------

update :

I switch back to B slot. And my phone can go into system normally. But it still ColorOs.
[OnePlus 12] Canuck Knarf:
Why is ColorOs is on slot b.. !!! ...using my bat file only flashes to slot a...where all phones from factory are flashed... something not right...or you not telling what you have done
[OnePlus 12] seraph758:
Can this be converted from 2583 to 2573 without formatting?
[OnePlus 12] gelopogita:
I just got a black screen after flashing. I can still access fastboot but only black screen.

Help me please :(
[OnePlus 12] Canuck Knarf:
tell what file you used ...etc.
[OnePlus 12] gelopogita:
I used all the files that can be found on page 1. I flashed the Indian Rom.

It is not booting up. Just a black screen.
[OnePlus 12] Canuck Knarf:
ok... put phone into fastboot...open cmd in platform tools... use command

fastboot devices

fastboot getvar current-slot

let me know what it say
[OnePlus 12] gelopogita:
Current-slot a
[OnePlus 12] Canuck Knarf:
good...now have phone in fastboot

run my bat file again...see what happens look for errors ( do not lock boot loader at the end of script)

screen shoot everything...post pics....
[OnePlus 12] gelopogita:
Whew. It worked. 😁. Is it safe to lock the bootloader after this?
[OnePlus 12] gelopogita:
Whew it worked! Is it safe to lock the bootloader?
[OnePlus 12] Canuck Knarf:
Just make sure all things work...complete setup...if all goes good ..sure can lock bootloader(y)
[OnePlus 12] gelopogita:
Everything seems to be working now. I just locked the bootloader. Thank you so much Brother :)
[OnePlus 12] Canuck Knarf:
Anytime
[OnePlus 12] ohmarkey:
I followed all the instructions and when my device restarts into fastboot the flash file would not continue, it says press a key but nothing happens and I have to reset the phone then I get a lot of errors, the phone boots into coloros, I have tried 3 times and cannot get it to work?
[OnePlus 12] Canuck Knarf:
Now before you run Bat file

1: Bootloader unlocked

2: Computer must see phone in Device manager

3: Must see phone in cmd ..adb devices and fastboot devices ...both with serial # of phone

Well if you put phone in fastboot...use bat file and doesn't continue...you don't have device manager open...and see that " ossi " driver is needed
[OnePlus 12] ohmarkey:
Bootloader was unlocked,

I'm unsure if device manager saw my phone,

but..

My phone was listed in adb devices,

The bat file started and it ran through a lot but then when it needs to restart into fastboot nothing else happens, it gets stuck. Then the only way to get out of it is restart the phone but then I get lots of errors.

ossi driver? I haven't installed that.
[OnePlus 12] gogitossj:
Do you recommend using your tool or this tool?
[OnePlus 12] Canuck Knarf:
First part is fastboot w...that will run...from fastboot...but flashing starts in fastbootd...which is ossi ...now you can...read this :

ok first off I tell people have device manager open...you need to install driver for ossi.... leave bat running ..open up device manage see if you see ossi error ...if so update driver ..you need " android bootload interface "

My bat file

1. Fastboot -w (from fastboot)

2. Reboot to fastbootd ( ossi ) need device manager open make sure ( android bootloader Interface driver installed)

3. script will start to flash after driver is installed

4. fash file

5. phone will reboot back to fastboot . ( unlock or lock ) Dont lock until you setup phone and everything is working.
