 Hi all
I´m new here, and i need some help please.
I´ve flash some wrong firmware in my tablet and now it´s bricked.
It´s recognized in windows rockchip batch with blue, green square whatever, but when i go to flash
it gives "download boot fail". I´ve tried also with rk android tool
but no luck either. I think the system.img, recovery.img. , kernel.img , e.. flash good, but i have no luck with
bootloader. I dont know why? It´s original bootloader and firmware.
The tablet is from Deco, Ocu consumidores but the new one quadcore, not the dual-core rk3066.
I think there´s a rom also from Oma, to the dual core tablet. This one is quadcore, new ones.
Can someone help please?
Thanks.

Hi
Yes i have the stock firmware, my friend made a dump.
He has the same tablet. Can you compile a update.img file? I don´t have Linux.
Thanks

Working with RKBatchTool is not a good idea. I guess the dump does not contain the loader and a parameter file?

Here is a flash pack for testing: http://crewrktablets.arctablet.com/?wpfb_dl=2709
The dumped files are ok. They are for the hardware revision with ESP8089 wifi.
Included kernel are:
- kernel #24 preempt 3 July 2015
- kernel #61 preempt 17 July 2015
You should find the running kernel in settings/About the tab.

Install the right USB driver first (see instructions.txt). When the tab comes up in Loader modus then use it.
If the tab doesn't come up in Loader modus you need to open it to short NAND pin 7/8 to start the Mask-Rom modus.

Hi
I got no luck with that flash pack. I don´t know what´s wrong or
is the miniloader version or something with the firmware. This firmware version is
4.4.2 or 4.4.4? In the parameter file says 4.4.2, but the Tablet came with 4.4.4 original.
In the dump files it has the 2.19 miniloader version, but i can only flash the 2.25 version,
the other version says download boot failed.. I don´t understand..????
