[Android Head-Units] gamalulu:
Hello all,

I am not a professional but still ambitious and would like to solve the existing problem

Since my English is not perfect, I use a translator, sorry if some written is not understandable.

Coming to my problem.

I bought 2 years ago from Aliexpress from a reputable seller an Android. 8227L YT9213A

From the beginning, the device was very slow or lost the GPS data.

original firmware was YT9213A_00009_V001_20200408

before the failed firmware update

As a result, the seller sent me a firmware "xyauto_ui1_9213A_full_8227L_demo-ota-20200517". I copied it to a USB stick (rar file not unzipped) and successfully performed an update via the radio menu "Android Update".

Over time, however, I noticed that the navigation "google maps " always crashed. also lost the gps data.

about the playstore to update the apps brought no success. the problem was in my opinion on the android system,

it was still slow and not fun at all.

I have now contacted the seller again and informed him about the problem.

he sent me a new firmware "gongban_YT9213A_ui1-hw-ota-v6.5.zip".

after some research i found the XY Auto firmware download page.

XYAUTO

file manager

file.xygala.com

there I found exactly the same firmware what the seller sent me.

I copied the firmware zip file to a USB stick and tried again to update the firmware via the radio menu "Android Update".

Unfortunately, an error occurred, I have repeated the process several times. tried different USB sticks but it always came to the same error.

I think that this firmware what the seller is not compatible with my device at all.

I have on the http://file.xygala.com site then a previous firmware and that is

"xyauto_ui1_9213A_full_8227L_demo-ota-20200523.zip" downloaded and copied the USB stick and again through the device menu" Android update" performed.

This time I noticed that it did not come to an update abort. it came the message 1 of 53 apps are updated, but at "23 of 53" it froze and the system was rebooted, then the installation continued "1 of 9 apps" are updated. Finally the message came, "Update complete".

then the system was rebooted but the startup screen froze, the touch did not work. the image distorted and after a few seconds the system was rebooted again. this phenomenon repeated itself again and again. so to say "boot loop effect"?

then i started to research on youtube saw some videos how the firmware was updated with flashtool. i wanted to copy it. I downloaded the "Scatter-loading file" from the firmware folder the seller sent me "gongban_YT9213A_ui1-hw-ota-v6.5.zip" ( but I downloaded the same firmware for PC update from the http://file.xygala.com site

downloaded) and loaded and thus tried to flash. the " preloader " in the first row was not activated. the hook was missing. manually I could not click either.

Then I tried to load the "scatter-loading file" from the previous firmware "xyauto_ui1_9213A_full_8227L_demo-ota-20200523" and flashed " Format All+ Download" it started to load at the bottom of the bar but then came an error message.

So now I think I have made things worse.

Now the screen stays completely black. Android loading process I do not see. I see short flickering but it remains black

The seller only answers when he feels like it and doesn't really help me.

It would be a shame to throw it away. I don't think it's a hardware problem.

Can anyone really help me from afar and give me a tip.

I would follow any instructions and try to revive the device.

thanks in advance and hope someone will help me.
