Development [CLOSED] [ROM][12L][16 Apr][Stable] DerpFest for OnePlus 9/Pro [OFFICIAL][Lemonade/Lemonadep]

[golfgtiedition30]

With this ROM, can we achieve full R/W capabilities on root partitions? I have the OnePlus 9 Pro running stock 11.2.9.9 with T-Mobile as carrier model LE2127.

Who cares , the rom's not been updated since April , move on.....

Using that on TMO stock 11, I was hoping that there would have been a custom ROM on A12 that was pre-rooted. Thanks for your reply!

I am on last DerpFest and get this notification. I think it's from Google. How to disable this update?

Maybe go into settings then developer settings and disable auto updates...

Is it OK to flash on OOS 12?
Does this rom include OOSCAM?

Dude this rom hasn't been updated in a while and no longer is supported and oos can has just been ported today the only rom with it currently is Nameless you can't expect developers to add it in less than a day

 

[chenxuwen]

Thanks for letting me know.
OOSCAM is a big problem for custom rom now. Oneplus 7 pro just got it recently. But 8T got it much earlier.

This is a small project based on AOSP. We try to be a platform for beginners and support the Custom ROM community with our own unique contributions as well. This ROM exists thanks to inspiration of AOSiP, Thank you! #StayDerped

I believe there is a msm tool that will set you back to or before this version.

Is dual sim working on your phone ?
