Question Are we going to see custom rom development? - OnePlus 9R

Since this oneplus 9r is china and india specific phone so it has low global coverage so are we going to see the custom rom development like other oneplus phones

Probably not.. Just need to see if 8T roms will work on this as we have almost the same setup.

If only 8T Official ArrowOS and Lineage could be brought onto this, would be perfect.

You could try building a rom yourself, you'll need Linux (Ubuntu is usually good), a decent sized fast drive (256GB SSD/M.2).
There are usually guides for building each rom on their github, you need the source for the rom and the source for the device (which OnePlus will upload to their github) plus guides on YouTube.
Resurrection Remix Github ( RR Guide )
LineageOS Github ( LineageOS Guide )
crDroid Github ( crDroid Guide )
PixelExperience Github ( PE Guide )
Project Xtended Github ( MSMExtended Guide )
OnePlus Github
The roms will usually have either a Telegram or Discord group if you run into difficulty, don't EXPECT a response though, REQUEST a response.
Here's the GSMArena page for the OnePlus 9R, GSMArena is an excellent site to find out info about phones and their chipset. This denotes the chipset for the 9R as :
ChipsetQualcomm SM8250-AC Snapdragon 870 5G (7 nm)
Here's the Github page on OnePlus for the SM8250, although it's labelled as OnePlus 8, the 9R actually shows SM8250-AC
Strictly speaking, you don't actually need the device to build a rom for it but I wouldn't recommend installing roms from people who build them like that because they obviously can't/have not tested them.

Expect the 8T TWRP to have support for 9R in the next build (not out yet) since I added the 9R to the unified script. Then maybe some more open source projects like Lineage will just unify 8T and 9R development.
Watch the 8T TWRP thread here for progress and that next build which should support 9R: https://forum.xda-developers.com/t/...-unified-stable.4101313/page-72#post-85274307
and you can use my adb insecure patching AK3 zip to get adb access from 9R stock recovery in the meantime here: https://forum.xda-developers.com/t/...-unified-stable.4101313/page-57#post-84204575

TWRP for 8T/9R is out now and has its own thread: https://forum.xda-developers.com/t/recovery-11-alpha-teamwin-recovery-project-8t-9r.4302449/
Edit: Unwatching this thread now.
