Hello guys!
After struggling with a dead MXQ with a Rockchip and a then with a new MXQ but with an Amlogic, here i am with an brand new H20 ready to go to garbage can hahahaha.
I made some test with this board and the processor is an RK32xx (32A if i remember well), but i noticed a few thing that may help to solve this board...
( i don't know if this topic is the right topic to write about, so, moderators, feel free to move or delete if i'm doing something wrong)
1 - The board don't boot from the sd card.
And when i say "don't boot", the board really don't boot if there's a sd card in the slot. Nothing, nada, niente, nitch... Only a blank screen and neither the Android shows up.
I've tried a SD with Multitool and with the uncompressed Armbian, and in the both cases the board seems dead
2 - The board boot the Android if there's an USB stick in any of the two USB ports
And the content of the USB is read by the OS after boot
3 - The image that's Rhodam posted allow the "developer options" and allow ADB but...
(quick note: My another MXQ - with Amlogic - have an UI that didn't allow the user to set the developer options, so i think that's important to tell).
I tested the online ADB from google and i couldn't find the device. I used the drivers provided in the link, but the app didn't find the board.
In the other hand, my pc recognize the board (with lsusb and with the "device manager" from Windows).
4 - rkdevelopertools don't work (was expected)
How i said, the pc recognize the board, but, the most important commands from rkdevelopertools didn't work. Some commands to gather information about the processor worked well (images below).
However the important commands doesn't work or don't have a practical effect. I tried erase the flash and the rk did it but the Android still working after that.
And sometimes the rk appears to start the "downloading of the bootloader", however the process need to be canceled because takes to long and nothing practical really happens. In the most cases, the red message of error appears in this process.
And while i'm writing this, i remember that i tried use and image (i don't remember if was an Armbian or an image from another tvbox) with the tool provided by Rhodam, but the software stopped at the beginning of the processes, so, this kind of "bruteforce" doesn't work too =P
Well, this is the progress i made yesterday, when i restart this project.
For now, i'm feeling stuck, but i believe i have all the tools (dual-boot pc, board and a male/male usb chord) to keep this investigation and try any possible solutions to make this work on this board, so, if you guys have any hint, thoughts or suggestions, i'm opened for it and i'll keep the forum up to date with the progress. 👍
Thank you for your time and for the rest, i believe my English was, at least, comprehensible 😃
