I have successfully installed this ROM on a P6210 and I can say that this goes pretty well compared to danielhk for some reason. Seems pretty stable, no random reboots (up time: 47 hours and counting), no sluggish system, so far, is good to try it.
The only small issues I've found (and they're well known), is the WIFI connection issue. After some time being idle, it will turn off by itself. The other thing is, I don't use Youtube app to watch videos, just Firefox Focus for lightweight browser, and the playback in normal mode, it's all glitched with random colors and the audio gets stopped for a millisecond, but, if you put in full-screen mode, the video can be seen and the audio is working like it should be.
Thank you for giving my P6210 a new life!
