    If oall goes good it will be ready for release within a week.
    We had an USB issue on the current x5mini rom that has been fixed in the new one.

    This is not about going from 240 to 230 (they are both android 4.4 kitkat). Why do you want to go back to 230?

    to updaqte from 4.1 to 4.2 just flash the full firmware package you want to put on it.. this is only for degrading from 4.4 to 4.2

    Hi,
    I followed the procedure to downgrade my X7mini and have now the problem, that the PC under windows 10 lost the connection with the device after flashing the boot loader. Result is, that the PC does not recognize the device correctly and so does the rkbatchtool. I tried then with a Linux system using rkflashkit. It was not successful, too. The tool does not show any partitions on the nand storage, but it is detected.

    I hope there are some ideas how to repair...

    For anybody who may ask for the reason to downgrade. The X7mini did not remain in sleep mode after pressing the A2 Air Mouse power button, even if I deactivated the gyroscope. So it run night and day. Sleep mode did not work with kitkat rom 230/240. So i decided to fall back to the 011 ROM.

    Some additional informations:
    I found another software to connect to rockchip devices, it is called Linux_Upgrade_Tool
    The device is detected

    Followed this guide. Bricked device. Hey, thanks for making my x7 nothing more than a paperweight buddy. I suggest you actually TEST things before you post "guides".

    Just to let you all know the procedure above doesn't work. To be more specific, it works from item 1 through 5 but you will not be able to flash 4.2.2 roms again.

    I'm working for days into this and I'm stuck in 4.4.2 - unfortunately - due the lack of Bluetooth support (it connects and pair with the devices but nothing works).

    Take care people with this 240 version - I'm already stuck don't do the same mistake!
