10.25" Android head unit. No Signal. Link Sys 1

Martinakerman · 12-28-2023, 02:27 PM

No Signal / Link Sys 1.
I'm stuck after logo with a no signal text, link sys 1.
It was working for 2 years and suddenly this happens.
Aftermarket back rear camera still works.

I want to clear cache and data from recovery. Is that possible?
Can someone tell me how to get into the recovery mode?
Or flash a new firmware?

These units have a small hole at the back where is located the reset button but it just restarts the unit.

The only info I have about the unit is the screenshot you can see , i also remember the assword was 666666

I have also uploaded a video, have a look please: https://xdaforums.com/data/video/453...14165925c6.mp4

Thank you so much in advance!

Did you try holding the reset key for a while (some 10s for example) to see if the unit is factory reset?

Yes I did, 10, 20 , 30 sec etc , nothing, as soon as I release it it just restarts

Contact whomever you bought the unit from and ask how to perform the firmware upgrade.

Since the kernel works it's probably just fatal crash on the OS level.

Did you already try to do FactoryReset? You don't seem to have any other options.

When i had the android unit it had buggy software and there was huge thread about people upgrading them to get rid of anomalies.
Some got their issues fixed, others got units bricked. There are so many different suppliers and they all got different software versions. Flashing wrong one will brick the whole Android unit.
I decided not to upgrade since my MicroSD card slot was buggy - random disconnects and this would pretty much guarantee failed flash.
