I have the Oneplus 9 Pro LE2120 model with LineageOS installed (lineage-19.1-20220920-nightly-lemonadep). How can I install Oxygen OS?

With the OxygenUpdater app running on LineageOS it downloaded LE2125_11.C.48_1480_202204082113, so I'm guessing the LE2125 version of OOS works on LE2120.

Just use the MSM tool for your model to return to factory settings and then upgrade from there :


EDIT : Actually, if it's actually the LE2120 then it might be the Chinese one, don't think it has MSM tool, shouldn't it be on ColorOS?

The phone is "OnePlus 9 Pro 5G Dual SIM OxygenOS LE2120" purchased in Australia. So it is the LE2120, but it seems the LE2120 has OOS installed outside of China.

The MSM tools look useful, but as you said there doesn't seem to be a LE2120 version.

Yeah, The Chinese model isn't supposed to have OxygenOS that's why. I would guess that someone installed the Global build on it, so that should mean you can use the Global MSM.

I have an LE2120. The Global MSM tool will give a SHA-256 mismatch in the flashing process. But the EU MSM tool will work. :)

Thanks for the help, I got it working.

I installed Windows, then ran the EU MSM tool but got the error "Unsupported target IN". So I ran the India MSM tool which loaded the Indian OxygenOS 11 onto the phone. Then after a series of updates in OxygenOS using the system updater (one was over 4GB), an update to OxygenOS 12 was installed.

In OxygenOS it now says the phone model is LE2121.

    There is also the "payload flasher" tool
    from latest "full ota" for your sevice, extract the payload.bin and flash
    (maybe a bit tricky getting started, but it works the most of the times)
