Could someone with an original Oneplus 11R (CPH2487) with root access help extract and share their ocdt.img

Using ADB:

adb shell
su
dd if=/dev/block/bootdevice/by-name/ocdt of=/sdcard/ocdt.img
exit

EDIT: CPH2487 ocdt.img #1 added (not working, need another img for byte comparison)

Thanks for the help, just wanted to make sure you have the original Indian variant of 11R?

dump made from original 11r indian version , not ace2 with Oxygen.
unsubscribe about the result after flashing ocdt img

before flashing the new ocdt.img, do not forget to backup your old one on Ace2

about the result, whether it helped or not.

 

[simima30]

Ah okay, sure. I'll try to get it done within 3 weeks. Meanwhile, anyone who attempts it beforehand please let us know the results.

After flash global ocdt - screen not showing anything, but phone is booting
I reboot phone to bootloader (on screen still nothing) and just restore original ocdt

that's too bad, i was hoping it would solve the screen flicker for good

Did you flash it in both fastbootd and fastboot enhance?

 

[GTAstar]

Did you flash it in both fastbootd and fastboot enhance?

Yes
After trying - phone stop powering on, official flash through edl don't recognise phone

 

[Ano@951]

How can I enter fastboot mode when I reach the recovery screen and select the language, but there is no fastboot option available?

 

[simima30]

Use ADB on your pc while connecting your phone to it.

Just follow this post: Link

Dude, what you guys need is that same file but from Color OS, because it could be hardware difference too... And it works normally on Color OS for this model, so it should technically work, if it is compatible with Oxygen OS

 

[simima30]

We need the odct.img file of original 11R OxygenOS devices. We can obtain the ColorOS IMG already.

I thought the issue is caused by ODCT not flashing when we flash Color OS to Oxygen OS.

I thought the issue is caused by ODCT not flashing when we flash Color OS to Oxygen OS.

Which is why we need the OxygenOS OCDT file.

 

[leo52307]

But I'm wondering why @Rastatorba OCDT not working
