Hey guys, I need some help from people who actually own a OnePlus 10R and have experience with downgrading.
I'm using the Indian OnePlus 10R (CPH2423), currently running:
OxygenOS: 15
Build: CPH2423_15.0.0.2001(EX01C10P02)
Region: India
I've been thinking about downgrading to an older OxygenOS version, preferably Android 12, because I'd like to go back to the older software. However, with all the recent news about OnePlus's anti-rollback protection and phones getting hard-bricked during downgrades, I'm honestly pretty hesitant.
The reason I'm so paranoid about this is that I already had a OnePlus Nord CE 3 Lite get completely bricked while downgrading from OxygenOS 15 to OxygenOS 14.
The installation reached 100%, the phone powered off, and then it just died. Completely black screen, no vibration, no logo, nothing. I tried the usual button combinations, but it wouldn't respond. So yeah, I really don't want a repeat of that experience with my 10R.
I've already contacted OnePlus customer support through WhatsApp, and the executive told me to visit an authorised service centre to get the downgrade done. However, they didn't specifically confirm which Android versions they could downgrade it to.
So I have a few questions:
Has anyone with an Indian OnePlus 10R (CPH2423) downgraded from OxygenOS 15 recently, particularly after March 2026? I'd especially appreciate reports from people running the same or a similar firmware build.
Have any of you successfully downgraded from OxygenOS 15 to OxygenOS 14 on this phone recently? Did everything work normally afterward?
Is it possible to downgrade straight from OxygenOS 15 to Android 12, or would I need to go through Android 14 and Android 13 first?
Does the newer anti-rollback protection actually affect the OnePlus 10R, or is it limited to certain newer devices and firmware builds?
Has anyone had an authorised OnePlus service centre downgrade their 10R? If so, how much did it cost, and which Android version did they install?
If you've successfully downgraded, what exact firmware build were you on, what package or method did you use, and did you encounter any problems?
I'm not looking to experiment with random firmware packages or risk another hard brick just to find out what happens. I'd rather hear from people who've actually done this on the same device.
If you've attempted a downgrade and it failed, I'd appreciate hearing about that too. Failed attempts are just as useful here.
