Can somebody pls test our CM12.1 build on Pipo P9?

Build v1.2.1: http://www.arctablet.com/blog/forum/rk3288-entwicklung-und-customroms-development-and-croms/cm12-1-has-landed-on-rk3288/

Use Kernel #30 and change kernel and resource in folder rockdev/Image before flash: http://crewrktablets.arctablet.com/?wpfb_dl=2606

Edit: choose TWRP 1920 x 1200

First boot is in TWRP: do a factory reset and install this P9 model fix (updated): http://crewrktablets.arctablet.com/?wpfb_dl=2632

Reboot system and wait 3 minutes.

WOW,

CM12.1 is great, thanks for the build. 

While installing I had to use TWRP_1920x1200_CrewRKTablets_v3.0.img from the AOSP P9 package. The resolution was too big to fit the screen.

Now testing the performance, it's very smooth (subtitles "lag" on Kodi player is gone). Got 35652 from Antutu benchmark.

Some notes so far:>
- No camera, front or back
- No GPS
- Bluetooth speaker doesn't work (weird noises, or no sound). Internal speaker seems to work ok
- Backlight adjustment doesn't work
- DPI setting too high, maybe 240 ok

Thank you for testing! Can I have a screenshot of settings/about the tab?

Sorry, I haven't thought about TWRP. However, you have found a good one.

Here is a brunch of TWRP's: http://crewrktablets.arctablet.com/?p=5336

Camera I am not sure at the moment.

GPS is a missing driver in the kernel #30.

As for bluetooth speaker and backlight adjustment: is this working in ASOP with kernel #30?

The dpi could be adjusted in settings/display. P9 has 240 dpi.

Sure Oma, here's the screenshot.

I'm not sure about the bluetooth speaker, but the screen brightness was working.

The DPI I adjusted from settings and now it's ok.

CM12.1 is FAR more better than AOSP for me, and I think this is the way to go.
