Help MK809IV with RK3228B DOWNLOAD IDB FAIL problem

[teko99]

I bought this product a month ago and it was working well but suddenly it stopped on starting screen (MBOX...)

When I try to format it gives failure such as on the attached first photo.

Then I tried to flash rockchip batch tool it says "DOWNLOAD IDB FAIL" such as on the second photo.
I also tried with the tool which is provided by the seller from aliexpress but is giving the same fail as on the third photo.

Any ideas to fix this problem?

is there specifically RK3228B tool or recovery img?

you can try to use another program, newer version. for example Android tool 2.35-
but when you have idb error, 99% of time is memory broken

I try to make a bridge between E and G and the light changes to blue and still not working T.T

You need to get the Device to Mask ROM Mode.
All you have to do find nand chip and shorten the pin with a paperclip.
When you found the right pins it goes to mask rom more.
Then you can reflash.

I connect in series E AND G and it turns blue but it always gives error adb device fail. (and in the process I hear a sound of connected and disconnected usb)
