Is anyone able to help me identify what unit this is? Its meant to be a higher end unit but finding it really sluggish and also looking at some of the reports its using > 6GB of ram OOB out of 8GB (Not sure how the 2GB unit would have worked) .

Sometimes when turning it back on from standby when playing music etc its really jumpy as its its doing something in the background. Anyone got any recommendations on apps to show what using up all the CPU?

It appears to be a UIS8581 based unit, I have run the HWGetinfo tool on it but its reporting its not a FYT unit.

Bit harsh - I have been search but how am I meant to know to search for ZLA not ZLH? Also, searching for "ZLA_" returns a total of 1 hit, a google search for `XDA developers "ZLA_"` also returns just a couple hits not in this forum?

ZLA was a typo... sorry.
My posting was not meant to be harsh, but this unit is really completely unknown on XDA.

Talking with the seller, mine was sold by COIKA.
It seems that it follows some patterns that are very similar to other HU's, you just need to make the following to update for example, the boot logo:

Folder structure:
- HUTUpdate
- OS
- bootanimation.zip
- logo.png
- upgrade.en (empty file)
- upgrade.system (empty file)


So, if you find other examples of HU types that are Android-based, this may work.

To upgrade the MCU is
- HUTUpdate
- mcu
- upgrade.mcu
- BMW_8581.bin

I was trying to make backups with other tools, but no success yet.

I have also an UIS8581 Unit von Coika. I have software version ZLH_AD_OS_1.86, and MCU LZH_qxha20830A_Q3H0_8581...

I have also some problems... the bluetooth does only work as a headset. you cant switch it on and use it as a normal conection for apps.

Once you switch to original system and then back, all apps are closed( spoitify etc) you need to restart them...

also my sim does not work at all, cause there is no APN setting in the system. once i try to enter it it says user is not able to change settings...

all in all the system is nor really well programmed and has lot of bugs.
If there is anyone who can help with get all the normal functions back pls contact me?

Best regards

Thomas

I use my phone via original Bluetooth on the car. I don't use zlink anymore. As I have the headunit online it makes it easier to use gmaps etc directly.

Do you have a SIM card installed? Does it work? My one does not connect as there is no apn and I cannot set new one. Did you bought it from coika?

I don't know who is the main manufacturer. Coika says they are the own manufacturers. But don't belieb them. Struggling with the service people since days... Apps are closing after you switch to car system... bluetooth is only working with mobile phone...no obd device etc... SIM card is not working...but they keep me waiting

Similar unit here (Mercedes version):
Version: ZLH_BZ_OS_1.80
MCU: ZLH_BZL221030A_8581_13
Android version 12 (fake - it's 10 - see below)
More info in attached photos.

The 8888 code gets you into factory settings, as in this thread: https://forum.xda-developers.com/t/...-not-fyt-based-read-first-post-first.4525675/

I installed the "Fake Device Test" app and it closes after 1 or 2 seconds (possible sabotage by the device?) but I managed to get the OS info by quickly flicking down the screen while videoing it, then playing back in slow motion. This confirmed the Android API level as 29 (ie Android 10). It also seems to confirm the claimed 8GB RAM and 1920x720 screen are correct.

I want to have a poke around with ADB and busybox, but so far haven't been able connect. The unit claims to be rooted.

Wireless Android Auto works, but one minor annoyance is that my phone seems to give up on Android Auto before the unit is ready to connect. A quick toggle of bluetooth and reconnect to the unit once it's ready is necessary. Also, you need to use a cable for AA when the ZLink app on the device is set to HD - wireless AA on HD delivers a pillarboxed display.

And despite all the images on AliExpress showing 5 icons per page in the launcher, I've only got 3 per page. Is this launcher configurable?

I don't know why exactly, but I have a nagging suspicion that the screen might be a lower resolution than reported, I need to see what the kernel/sysfs says. Do these units have a dmesg somewhere? Or could there be a problem caused by the screen being reported as only 7 inches, as I saw in the output of one of the System Info apps I tried? (Screen is actually 10.25 inches.

One thing I really want to do is get a full backup in case of future problems. Is using TWRP possible on these devices? There is a 1.5 GB "update.zip" on the internal storage, I need get a copy and examine it.

Investigations continue, I'll report back. In the meantime, does anyone have any thoughts on the above?

    I was just sent this BMW update ZLH_BM_OS_8581_1.94 . This will work if you have the Unisoc UIS8581a processor. Im not sure if it will work with snapdragon. It is still full of bugs and didnt fix my idrive issue.

    I don’t know if I was unlucky but just a heads up, I was sent the 1.99 version ZLH from Coika too and it failed partway through the installation and now my HU on the android side doesn’t work at all, stuck on boot screen loop, fast mode and every minute or two it goes into recovery mode, fails and then reboots. Which I am currently trying to fix
