Hey guys, my HU is a LE-6321 6G / 128G:

k4811_nwd_s212102.20240103.212453.H4F9.01F

I can`t use any gamepad to play games, for some reason buttons are linked to system shortcuts:

start button = switch screen on/off

button 1 = back

and so on...

Any ideas on how to solve it?
[Android Head-Units] peecee55:
This has been asked before but no one answered. I would love to know too. There is a site on telegram called 2DIN which has a lot more info. Unfortunately it is in Russian but I have used Google Translate
[Android Head-Units] marteline:
Wondering if is safe to replace k4811_nwd_s212102.20240103.212453.H4F9.01F

with this one: update_MOD_K4811_NWD_S117851_20240309.102225_root (1.2G)...

but I am afraid that s212102 and S117851 are not for the same hardware... Did anyone tried?

Hi all i get android multimedia from aliexpress. Beside i got tricked by version i gor 6gb ram lower grade cpu and lower resolution and disk space is 128. And i order 8gb ram bit better cpu, 2000*1000 resolution and 256gb space, i got new problem. He work one day and blue line appeared on the screen. Im currently in dispute on ali but i doubth that they will refund. This is probably display or gpu problem. My question is, will it spread, is there any possibility to repair it. Beside that il post my info and ask someone here who know witch is latest firmware for it.
[Android Head-Units] marteline:
Fixed using new firmware: magiskK4811_NWD_S217512_20240524_135526_1590c49280f137a959b05412fcd2c9bd.zip

I can confirm this version works flawless on LE-6321.
[Android Head-Units] marteline:
It seems to be related to accessibility settings. But I still haven't found a solution. I tried changing the .kl files in the /vendor/usr/keylayout/ and

/system/usr/keylayout/, but so far nothing.

I also tried removing all the .kl files and the back and power buttons on the panel stopped working (fixed by replacing the files and restarting).

Any thoughts?
[Android Head-Units] marteline:
I finelly found the issue: they maped pannel keys in a weird file using gamepad button codes: NwdKeyConfig.kl in data/nwdappconfig/app/

I kind of fixed it in attached file... but Volume buttons and power button will stop working. I binded them with new codes, so I will use tasker to regain control for now.

Enjoy!

Dear experts,

I rolled up to page 56 but unfortunately I found no clues on how to solve some Issues I am having with my HU.

- Side buttons does not light up / appear (could my HU not have the buttons???) bought if from RNABAU in Aliexpress.

- There is an ultra annoying temperature box that keeps hanging over everything on screen. I can move it from one way to another, but I want to delete it

- I cannot connect my phone to ZLINK it says that it is inactive. When I try to activate it connected to WIFI, it says "invalid SID"

Any clue that might help me to get rid of these issues?

Thanks a lot

Good afternoon everybody,

Finally this weekend I managed to start the camera, basically I had to cut the pink wire that goes from the stereo to the canbus and connect the cable that came from the camera to it, now it works perfectly.

Yesterday I realized that the images are the other way around, that is, the cars on the right are on the left and the cars on the left are on the right, the Up and Down part is correct, do you have any ideas on how to fix this?
[Android Head-Units] enzo60:
why not ask before buying? it is certainly a car tablet that does not have the specifications as per your request. This is a dishonest seller. Post the link where you purchased it
