Gents,

This is my first build for Pipo P8

P8 by Oma build v1.0

update 06.12.2014: kernel #194 (change kernel & resource in folder rockdev/Images before flash)

update 01.01.2015:

- corrections of some wakelock issues of the stock firmware/kernel
- some minor corrections
- TWRP 2.8.3.0 in Portrait inlcuded

P8 by Oma build v1.1

– stock recovery 4.4.0
– kernel #167 [v1.0], kernel #170 [v1.1]
– CrewRKTablets TWRP 2.8.3.0 [v1.1]
– 4 GB internal storage
– init.d support
– multi-user
– latest hosts, su, su-binary, busybox
– Reboot Menue, sEFix, FX Sound
– Dateimanager HD (Root)
– Nova Launcher

Flash instructions are included in the download pack.

Hints:
– to improve UI feeling: disable all animation scales in developer options,
…use Nova launcher and set animation/scroll to “faster than light” and
…enable Entropy Fixer with value 256
– to improve battery drain set keep wi-fi on during sleep to never
– to get full access to the build enable /system rw in File Manager HD
– to disable su notifications change notification in settings/SuperSu
– to prettify the build use Xposed Framework > Starter Pack

Be aware: it is your own risk!

OMA..

Thanks for the ROM.. These are my findings:

Kernel 203. The input sporadically stops working when entering the lock-screen. If for example you create a lock-screen pattern then press the power button to lock the device then when pressing the power again the lock-screen appears but is not accepting any input when touching the screen. (This happens 1 out of 2 times especially if locking and unlocking rapidly).

So then I changed to kernel 167. In kernel 167 GPS is not working for me. I have not tested 3G but intend to do so asap.

3G. Wifi. Bluetooth. HDMI all works for me in kernel 167. The only thing I cant get working is GPS and I don't know if it's only my P8 or if it's the ROM.

Your tab should be delivered with kernel #167 or #153 or below. There is no official firmware published on Pipo site, yet. So, I guess all what we have is still in beta phase.

Can you describe what exactly is not working?

When using 'GPS status and toolbox' and 'GPS test' the device never locks to my position. I was standing outdoors for 4-5 minutes. resetting GPS data and so on.

I can provide detailed data however please advise on how to provide it.

Another off the topic super annoying finding is that it's not possible to charge the PIPO P8 'turned off' the device is turning itself on and booting when charging.

Thanks for helping.

Did not notice any difference when installing kernel #170. GPS is still not working and the device boots when connecting the charger.

We know that GPS works with the P1 build. You may be test this: http://www.arctablet.com/blog/forum/rk3288-entwicklung-und-customroms-development-and-croms/rom-pipo-p1-4-4-2-custom-root-firmware-20140820/

Make sure you change kernel and resource in folder rockdev/Images before flash.

OMA.

The P1 ROM with PIPO P8 kernel #170 (kernel and resource file) gave this result:

boot screen came up (the PIPO one before the OMA logo). Then just a black screen. The flashtool reported a device but the display was totally black.

So sorry can't test the GPS since I could not boot the device.

Talk to you later,

I confirmed with the 170 kernel I do not have GPS.

Thank you for your work and your rom.

I hope you find the problem of GPS, and tell me how i can help you.

Enable your location in settings and test with this app: https://play.google.com/store/apps/details?id=com.androits.gps.test.free&hl=de

Do not await the same performance then a smartphone. It could take very long to start. Best is you let it run several minutes in the open air.

Thank you for your quick response

Is there a way to improve the battery?

Hehe.

Battery drain is a more philosophical question ... install an app like this and track the data a few days. Maybe we will find some irregular things.

OMA.

I also got GPS working using that GPS app. Took as kiko95 pointed out 10-15 minutes.

Is it possible to modify the boot routine so that the device do not boot when inserting the USB charger just like all other android devices i know of? Or is sourcecode needed for that?
