[Android Head-Units] nsanders90:
Heyyyy guys, so I've got a Dasaita MAX10/PX6 android head unit for my corolla. Bought new in December of 2020. I've never updated it or anything, always ran totally fine. About 2 weeks ago it totally shut off while I was driving.

I've confirmed all of the fuses, including the fuse in the unit are fine. I am also getting ground and 12-14.8v at the harness on constant and accessory. When I did finally pull the unit out of the car I noticed that the ground was no longer attached, but not sure If I yanked it out from where it was when I pulled the radio OR if it came loose and that is what caused it to shut off; either way re-grounding it, same deal. It won't boot up.

I can get the button lights on the screen to light up, and the blink/flash when I hold the RST button, but it never shows anything on the screen. I also picked up another unit (not a Dasaita, just a random cheapo that happened to have the same screen) and hooked that up just in case my screen died. But that does the same thing. Also plugging a monitor into the HDMI out on the unit shows No Signal on the monitor.

I made a wall outlet plug for it to speed up testing since working in my car was a PITA. Same issue outside of the car plugged into a power supply. I can get it to sort of attempt to reset but nothing appears on screen.

I then took the whole thing apart and disconnected all of the ribbon cables and removed the coreboard and reattached everything - same results.

Soooo I'm not sure if my coreboard is totally shot, or if its worth attempting to recover the SOM with a custom cable.

I also stumbled into this: https://www.aliexpress.us/item/3256805119609170.html?spm=a2g0n.productlist.0.0.3b00178e1LqUWJ&browser_id=276e8aff87cc4dabb30f5c59f2bdc799&aff_platform=msite&m_page_id=zetwhgerlccauysr1885ee4fb90185a9d285ecd0a1&gclid=&pdp_npi=3@dis!USD!172.8!146.88!!!!!@2122443916852192449506903d0790!12000032566253924!sea!US!0&algo_pvid=d5ec49b7-856f-4398-90ea-6e1e11b2ee01

^^This appears to be a replacement board, will popping this in fix my issue? (if it is the board) or are there additional caveats like drivers/firmware that I would still need to flash this with?

I have been loosely in touch with Dasaita, but I think due to the language barrier and time zone differences it has been a struggle, waiting a day+ for them to suggest something that I have already tried :/

Would love to hear from someone that knows what they are talking about! This is my first rodeo, prior to this though the unit ran fantastically - I had a handful of app crashes in the 2.5 years I've owned it, but simply restarting those apps worked right away. So I'm totally stumped for now.

Thanks guys!

PS: I'm also confused by the Dasaita megathread for firmware updates. They list the MAX10/PX6 needing one firmware but then they list the HCT-RK3399 PX6 needing a different one. My unit was sold to me as a MAX10/PX6 but my board (attached images) shows HCT-RK3399 So in the event that I am able to flash it, I'm not sure which I should be flashing to it.

I have also tried taking both of those update zips from the Dasaita megathread and putting on an SD Card formatted in Fat32 and putting into the units SD Card slot, but same results.
