Make sure you have the U23GTC4-W model. If you have the U23GTC4 use the firmware from post #1.

In any case, don't forget to use Restore button when flashing with  Rockchip Batch Tool 1.7.

Cheers.

Hi, I have problems when trying to install. I have not found the install guide this time and I think I may have the wrong kernel or something like that, because I get the message "check chip foul" when using restore in RKbatch, I should have installed something wrong and I don't know how to go back.

Ok, RK903 wifi.

Check out this KitKat v1.2 build: http://crewrktablets.arctablet.com/?p=2982

Kernel U23GTC4 is here: http://crewrktablets.arctablet.com/?wpfb_dl=1019

Try this model fix for 160 dpi first (install directly after format_NAND): http://crewrktablets.arctablet.com/?wpfb_dl=1816

Hi

I use ARctool to reboot in bootloader. This its the only way to RKAndroidtool find the tablet. Its right?

Did I have to change the kernel (the second one that you gave me) when I execute RKAndroidtool?

Thank you for your help

It should work also with a key combination. Is there a Reset? Try Vol+ and Reset.

You need to use the right kernel for your tab. As far as I know GTC4 or GTC4-W is the beginning of the Serial Number.
