Best is you use a PC with win7. Do not use an usb3.0 port.

I mean what you see on the tablet. I tried windows 7 , when I install the driver its OK, when I switch off and hold the power and volume up key, says device not recognized. Do you have any file to use with the update app to update locally

No, flashing is the way.

There are most likely other RK usb driver on the tab. Make sure that the RK Driver Assistant is in the c: folder. Run the Assistant and de-install driver first. Check in the Windows Device Manager if all RK Driver are gone now. If not uninstall them manually. Then install the driver with the Assistant. Now start the tab into flash-modus.

Hi Vicent,

Thank you for asking. To summarize: the P90HD is an almost perfect bit of hardware!

I own tabs with a Rockchip architecture since 3 years now. I started with a RK2918 Odys Loox (Pipo DS710), which comes with Android 2.3.1 and 2.6.32.27 kernel. Latest build is CM10.1 on 3.0.8+ kernel, overclocked and with zRam support. You will find some references of our work here: http://crewrktablets.arctablet.com/?p=3555

Now a RK3288 Teclast P90HD, which comes with Android 4.4.2 and 3.10.0 kernel. The kernel itself is only 5.5 MB, which indicates a high share of open source code ;-)

The Teclast hardware is pretty stable with the latest stock kernel. Quality level and look & feel of the tab is excellent, the JDI IPS screen is top. AP6210 wifi implementation is surprisingly good, best of all my tabs.

The Android UI experience is not better than on my rk31boards. Read somewhere there will be improved mali driver released. Still an creapy thing is the rknand driver. The advantage of eMMC is not used. Why no dwmmc driver?

Hi Oma, thanks for your reply.

It's our honor that you enjoy to use P90HD.

We can only use stable drivers which provided by Rockchip. Do you know how to port the driveres you mentioned to P90HD?

Hi Vincent. 

I really like this tablet. I bought it like 1 month ago and it's a very good tablet. 

Now I run official 1.18 firmware because the UI runs smoothly (with 1.19 I have lag in UI). 

I have 2 suggestions:

How about fix wifi location in the tablet? It doesn't work

I have too a little bug with touch screen. Sometimes when you touch a button he stay pressed like u stay touching the screen 1 second at least (I had zopo mobile phone with sale problem and they fixed with a new screen firmware). 

Thanks for your job. I really love this tablet. Keep supporting it!

Well, my last favorite tab was the Chuwi V88: http://forum.xda-developers.com/showthread.php?t=2310818

The company and the community profited a lot ;-)

We notice that Rockchip is now more open for sharing sources and best practice. So, why not looking into this driver/layer issue.

v1.2_01.pngImage Enlarger

Chip is likely something like that: http://www.datasheetarchive.com/dl/Datasheets-IS86/DSAH00529205.pdf
This chip should be good for ~100 MB/s.

Do you have the exact chip type and a detail of the RK3288-eMMC schematic diagram?

If you'd like you can contact me via PM for further discussions.

I have a couple of questions...

Is the original launcher a part of your rom too?

Can you turn the multiwindows-function on and off in the rom?

and What are your plans further along for the rom and the tablet?

 

Looking forward to see what you can do with this tablet.

Stock launcher is still included in the stock build.

For Multi-Windows you need to try the v2.x build. Multi window can be switched on/off in settings.

Ok, tought the KTU84Q 4.4.4 was the next build and you droped development on this build, but i understand now that its an aosp-build. So i missunderstod that.

Oh by the way, you gonna add touch to wake or something like that (come to think of it, maybe it already exists a module in xposed?), seems like a nice feature for this tablet.

 

Thanks for the answers. Im gonna flash this i an couple of days and try it out.
