Well, you now have a strange kernel in your tab ...

Partition layout does not fit for everything you do. You need to wipe partition layout first (eraseIDB).

Then use the parameter from the AP-715 image and your dumped files.

If system will not start you can also use system.img from AP-715.

- Oma -
[Miscellaneous Android Development] prav3955:
ok but tel me should i use recovery img from dumped images or the cwm u given

second thing which kernel img i should use

where i can find parameter file for AP.715
[Miscellaneous Android Development] Oma7144:
Parameter see post #1044.

Your kernel, of course.

Use stock recovery first.

[Miscellaneous Android Development] prav3955:
parameter file im unable to find...

about kernel.img...i have two images one which i dumped using emulator and second u checked and uploaded in archive...which one should i use

It's here in this download: https://disk.yandex.ua/public/?hash=ZAu373WcGbQW3LhkZ49UAQSKmdqhSzMWnxzZ3mH4qKU=&locale=ru

Use the kernel from the archive.

Flash the CWM with your pack used. Tick parameter and recovery.

Run attached fix via CWM (don't unpack).

hi again....nicely done...now can u suggest some mods, tweaks, for my tab...rk2928sdk...thanks again man
[Miscellaneous Android Development] Oma7144:
I guess the rom is good as it is.

For documentation purpose, here is a full pack: Oma_RK2928_iball_slide6309i_stock_cwm_root

It inlcudes:

- RKAndroid-Toold v1.35

- parameter and loader RK292x

- dumped and cleaned stock images (boot, kernel, system)

- CWM (recovery) and format_NAND script to format the user partitions

- root script

- instructions (maybe other key combination)

Open an own thread and find others to work on the RK2928 stuff. Good luck!

Hello Oma

First let me thank you for making a custom rom for the forgotten tablets.

But I have a question.

I have a viewpia TB-210 now I have seen that you can use this rom for the viewpia tb-110

Do you think I can use the same for the viewpia-TB210 if yes can you point me in the right direction

In other words elaborate a bit more how to install the costum rom

I flashed already more custom rom on for instance galaxy S2 and galaxy tab 2 10.1 but this way is new to me and I don't want to wreck my wife's tablet

Thx in front
[Miscellaneous Android Development] Hessa:
Hello Oma I'm tried to pull a system image from my ViewpiaTB210 with adb but the problem is there is no available driver for it so it is not seen by windows and also not seen by adb also tried the website itself but nothing.

Is there a other way to get a stock firmware or system image ?

Once again Thx for your help
[Miscellaneous Android Development] Oma7144:
In this pack are all driver, also for win8: http://crewrktablets.arctablet.com/?wpfb_dl=898

Use an USB2.0 port. Driver should be installed automatically when tab is set to: MTP and USB-Debugging.

Oma, I'm getting some problems... (semi-bricked)

Ok, I flashed the cwm but when rebooted the tab makes a loop.

In normal boot it gets stucked at the tux screen.

In cwm mode shows the tux and then the screen of the cwm but no long.

I tried to enter in the flash mode but the PC doesn't recognize the tab.

Any idea?

Edit: Now due several intents I loaded the cwm deleting cache dalvik and data... Wish me luck !

Hey Guys,

Hope someone can help me.

Yesterday, i tried flashing this to my Acho C905 tablet.

It all went well, then booted up fine, then went in to CWM.

I flashed the model fix, via CWM and rebooted.

Now the tablet, wont boot, cannot access recovery or flash mode and when I plug it in to my PC, it shows as unknown device??

Any Ideas how I can sort this out??
