MXQ-4k Bricked < Test Device Failed > (RK3229) (H27UCG8T2ETR NAND) (R329Q_V2.0)

[jeft01]

Riqsu , hi!

I have same board as yours and I have the same issue: the box was of a friend of mine. He gave it to me with 6.0.1 Android that had problems with Google account. So I first tried to reset cache, but it didn't work. So I flashed it with another ROM and I've bricked mine.

Now the only firmware that works for me is this one, but it doesn't have wifi and LAN: https://mega.nz/#!99oUya6I!OSXh6G70a...GYGstr0jFv1z84 (it is from a MK809IV stick).

Try to flash this in MASKROM mode, doing the short you already do. I use both AndroidTool 2.35 or Rockchip Development Tool, if it's hard to find, I'll send it via mail.

BTW, are you sure that the "stock" rom you are talking about is really the stock one for your board? There are a lot of MXQ 4K clone, with different boards, so a "stock rom" is not for every MXQ 4K.

plz help how to use maskrom and give me a link with instructions plz thank you

No comprende espanol
English Please
Here is my guess
Wrong firmware does not match rk3229
Waiting For Mask Rom Start is not that bad it means the firmware is compatible with rk3229
You only need to short pins to force cpu to wake
