Hello,

I have this tablet Denver Tad-97052 Specs here: http://www.denver-electronics.com/denver-tad-97052/

I know that the tablet has an RK3066 Processor, and that "OMA" made some roms to work with that processor.

I used "OMA ROOT and DUMP" pack to root the tablet and make a dump. Get it here: https://onedrive.live.com/redir?resid=F36CB19AF152B1C2!1592&authkey=!APNyLgUQppIYjE8&ithint=file%2czip

I want to now if it's possible to install this recovery: ClockworkMod (CWM) Recovery easy install for RK3066 and RK3188.

Also would like your advice, wich customs roms made by "OMA" could work on this tablet. I would prefer a Kitkat rom, if possible.

Need to know if its possible to resize the nand partions of the tablet? and how to do it?

Becouse the system partion has only 0.99gb and quicly gets full, and i don't need 5gb in the user partion, also 256 mb in cache partion isn't to low?

If you need any more information, just tell me.

Tanks...

Ok, kernel is now in the archive: http://crewrktablets.arctablet.com/?wpfb_dl=2572

With a 3.0.8+ kernel latest possible build is JB: http://crewrktablets.arctablet.com/?p=1913

Just change the kernel in folder rockdev/Image before flash.

Do a factory reset and let me have a dmesg log.

Thanks Oma

I tried it, but no luck.

I tried both fix installed via CWM recovery and restart, the problem persists

Then tried factory resert and 1 on fix installded, one at a time, all the same:

Wifi always off and doesn't turn on

Bluetooth always off and doesn't turn on

Internal Storage 2.46gb, but internal SDcard not working (says its currupted)

have i have done a dmesh log with the two fix installed, just in case you need it. here https://onedrive.live.com/redir?resid=F36CB19AF152B1C2!1595&authkey=!ACFVfHCzUw2RQKs&ithint=file%2ctxt

do you have any more suggestions?

Interrestingly the log shows the chip is up and running.

<4>[   17.379558] Current WiFi chip is RTL8188.
<4>[   17.433488] WIFI Power on.

As for the partiton issue: do a clean install using the generic stock recovery first: http://crewrktablets.arctablet.com/?wpfb_dl=1036

Copy the file in folder rockdev/Image (rename the old one in CWM.img first).

In Android reboot to bootloader (RebootMenue app) and flash only (untick all other) the CWM.img (rename to recovery.img first).

Then try the fixes (if necessary).

Once again thanks!

With your instructions the internal sd card is fixed.

But the wifi and bluetooth doesn't work, i will explain: when the tablet starts the settings say that wifi and bt are off and i turn them on, then it waits a while and the wifi and bt go to off again, i try again to turn them on, but now goes strait to off.

i made a small video for you to see it happen, here: https://onedrive.live.com/redir?resid=F36CB19AF152B1C2!1605&authkey=!AMxs9wnjOp_5x2A&ithint=file%2cflv

an extract of the dmesh log where the problem happens (i think)

<4>[ 186.375969] WIFI Power off.
<3>[ 211.534836] wait for new frame start time out!
<6>[ 211.945188] request_suspend_state: sleep (0->3) at 211950400860 (2015-06-24 21:22:07.723184150 UTC)
<4>[ 212.035016] Current WiFi chip is RTL8188.
<6>[ 212.050055] rk30-hdmi rk30-hdmi: Removed.   " i never used hdmi port"
<4>[ 212.107368] WIFI Power on.
<4>[ 212.562115] wifi_early_suspend

dmesh log here: https://onedrive.live.com/redir?resid=F36CB19AF152B1C2!1596&authkey=!ACl25JIdjYSwoKc&ithint=file%2ctxt

also de cameras (front and back) are upside down.

Any suggestions?

2 questions:

1. can i flash my initial dump, and restore the tablet to factory?

2. can i flash my initial dump on top of your rom and keep partion sizes? 

Thanks

You will find the same messages into you stock dmesg. So, unfortunetly no idea what's going on here with your stock kernel.

Yes, you can flash your stock images using the CM10.1 flash pack. Copy dumped images over.

Do NOT use other kernel! You will most likely brick the tab.
