Gents,

This is a build for ESP8089 wifi ;-)

2nd hardware revision with other sensor: pls use kernel #607 http://crewrktablets.arctablet.com/?wpfb_dl=2582 (copy uboot, resource, kernel in folder rockdev/Image before flash)

3rd hardware revision with other touch controller: kernel #619 > pls dump the firmware first and ask before doing anything!

Oma V17HD KitKat build v1.1

– stock recovery 4.4.2
– CrewRKTablets recovery TWRP 2.8.4.0
kernel #531 preempt 21. Jan 2015
– 2 GB internal storage
– init.d support
– latest hosts, su, su-binary, busybox
– full google apps support incl. Play Store
– Reboot Menue, sEFix, FX Sound
– Dateimanager HD (Root)
– Nova Launcher

 

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

– battery drain > set keep wi-fi on during sleep to never
– full access to the build > enable /system rw in File Manager HD
– don’t show su notifications > disable in Superuser
– to prettify the build use Xposed Framework > Starter Pack
– to enable multi-user use the Xposed module Multi User

 

Flash instructions are included in the download pack.

 
Be aware: it is your own risk!

Hi Oma,

I have a Chuwi V17HD Q8G1150100921.

Came with kernel 531.

 

Now trying this rom but I do not get found one loader device but get found one ADB device.

It tells me mach device type failed when I try to do something like format or run...

 

Yesterday I succeeded with a 2nd gen Chuwi thanks for that rom! I guess this must be a 3rd gen correct?

 

TIA

Tried the Kemper Build,

 

Androidtool finds one loader device  now working, using the kernel from your above build.... Does not work...

 

Retrying with the Kemper Kernel.... No luck sofar...

 

My bad... only changed the kernel forgot the boot and resources, now looking at oma screen.... Device starts up with a football pitch... Alas orientation is off.

Now applying the fix.. takes very long...

Does not work... I am stuck with the wrong orientation... any help?

Retried the fix... finished within 10 seconds and the orientation problem is fixed! Thanks...

 

Only just noticed that trw has fixed the timezone ... to the wrong zone... any way of undoing that.. again user error... should not have meddled with it...

What is the difference between the Kemper build and your above build please?

Thanks for the help!

 

BTW the tablet now runs the Kemper and Straus build with the RK3126 Kernel and the orientation fix...

Fine. There should be not much difference. The build in post #1 is done based on a dump from the tab. Reason was that someone claimed a quality issue with the headset output in the Kempler&Strauss build. I am still of the opinion this is hardware/kernel related.

Hi Oma,

 

I do have a small problem. Though everything seems to work fine I cannot install the "run frozen princess" app.

Downloads just fine but then fails to install. Tried it several times. Other apps do not have problems.

Where can I find detailed error messages please and how can I clear the cache?

Thanks in advance.

OMA - I sent you a download link to the dump as a PM if you want to take a look. Otherwise, let me know if you want me to check something. 

Best regards,

Ok, should make no difference. Here is the kernel #607: http://crewrktablets.arctablet.com/?wpfb_dl=2582

Use the build in post#1. Change the files in folder rockdev/Image before flash.

Oops I think I've done it now..

Because some apps did not install tried to install the build from post 1 instead of the kemper build per your advice....

Got the device into bootloader mode with the app and flashed the files from post 1 above with the 531 kernel files... Now the device starts up shows the dead droid with the warning flag and later the androidtool finds one ADB device... Switch does not work, got no volume buttons... Is the Chuwi deceased?

HELP please

TIA
