Check if your unit is MTCE or MTCD (see my previous post), and if it is, you can find the .apk files in this very thread. Just go a few pages back.

EDIT: you can find the .apk for Zlink 4.0.37 in this thread, page 18

Anyone out there can help?

Have a Xtrons TQS700L (PX 6)head unit that states it has built in wired/wireless Carplay and wired android auto running HAL V5.

When i open the Zlink app V4.0.37 (built into the V5 rom) I see the following

trying to activate(wifi connected) just brings up error message.

Is there something I'm missing?

Suggestions welcome.
[MTCD Android Head Units General] Apollon2:
Did you have zlink in your original stock rom? If not, you probably won‘t be able to activate it and should try to install the corresponding app that was delivered with your device.

Hi, I just updated Zlink app from v 3.5.54 to v 4.0.37 which is uploaded in this thread. It looks installed and actived correctly, but It won't connect to my iPhone. It is just stuck at the Apple logo and Connecting text screen. My head unit info is as below.

MCU: MTCE_CHS_V3.40_1 Nov 4, 2019

Kernel: 4.19.101+

Build: rk3399 (PX6)

Android 10, 1280x720p, 4G, 64GB

Zlink version installed when I bought: v3.5.54

Please help how to fix the issue or go back to the original v3.5.54

Thank you,
[MTCD Android Head Units General] ikerg:
How did you perform the upgrade?

Are you rooted?
[MTCD Android Head Units General] Golfboy333:
I put the 4.0.37 apk file into USB stick and opened the file with the Filebrowser on the head unit. The apk file installed and activated automatically. when I click the “About” button on the Zlink screen, it shows “Activation Successful [codexxxxx]” and honestly, I have no knowledge about rooting. and Zlink is stuck at the below screen. thank you in advance.
[MTCD Android Head Units General] ikerg:
I would recommend you to install a newer ROM version for the same android 10. Newer versions have newer versions for zlink
[MTCD Android Head Units General] Golfboy333:
I will research and study about it first because I have no idea about rooting and Rom update. I am a very beginner about this forum and Android auto. Thank you for the advise!

Uncompress and copy the resulting update.zip into root folder of an USB drive.

Insert it on the unit usb port and it will ask automatically for an upgrade file found. I suggest you to perform the uograde by ticking the option of wipe data.

This may be an unrelated question to this thread, but I am having a problem that when on Carplay and I make a call, the other party cannot hear me or its very low voice to them. I thought originally it could be my mic problem on HU, but Siri command works fine, also that without carplay on normal bluetooth calling everything is okay. So could it be anything to do with Zlink app itself or any other issue? If someone else faced this problem and have a known fix please suggest. I found many other old threads on this problem, but nothing with a solution. TIA.

How can i find the OG firmware for my specific Max6 device? I bought this unit back in 2019 and had no interest in AA at the time, so i cannot remember if z-link was installed or not, but looking at the amazon listing i purchased from (Saita Navi) store I should have AA/Carplay, but when I enable z-link in Hal9k v5 factory settings all i get is "inactivated" not sure if its user error and really dont feel like reflashing this rom and reinstalling everything all over again..

what exactly is the hardware difference in these models that do/dont have AA support? are we positive it isnt just a matter of software license validation?

Ive actually tried every app in factory settings. Hicar, easyconnection, ect, ect... all with similar not registered or not activated results
[MTCD Android Head Units General] iagobkstar:
The best way to get the manufacturer's ROM is to directly ask the seller of the radio. They may also be able to tell you if your headunit has Zlink support. Just one small detail, when you first open Zlink (on a radio that has Zlink support, but you flashed a new ROM), it sometimes says your app is inactivated. This is usually solved by simply connecting your headunit to the internet and opening the app again. If this hasn't solved it, it doesn't look good.

i bought a new head unit and found zlink wouldnt auto reconnect when getting back in the car, i had to disconnect bluetooth on head unit and reconnect. spoke with seller of unit on aliexpress and they told me to update via the zlink app as there was an update for the problem. this meant i got the 4.0.41 apk but it wont install. comes up with "App not installed" also tried installing via adb and it looks like zlink is a persistant app and you cant update persistant apps. told the supplier Awaiting a response from seller.

Any advice?

Since the update to version 4.0.41 the microphone no longer understands anything I say while in other applications the microphone works perfectly.

Do you have the same problem ?

[MTCD Android Head Units General] agent-orange:
I have the problem with zlink, that when I get a notification from whatsapp or google notification, the music is muted afterwards and I only hear the music when I get a new notification or google maps is telling me where to drive.

Also when somebody is calling me, the audio is extremely low. But when I turn the volumne up and I finish the call, my ears getting destroyed when the music is starting to play again^^

Can I adjust the calling volume somwhere seperately?

Hello,

I have the same problem like almost all of the users in here....

I have Android Car Radio unit with ZLink and I have troubles with my kid, he uninstall some app and one of them is ZLINK and now I can have acess anymore to my CarPlay / Android Auto...

If some can help me it will be great....

I have Android 10 unit

And the Z-Link says:

Channel Err! CHANNEL-MISS-MATCH!

apk:[zhuoxw]--Z:[zhangxun]
[MTCD Android Head Units General] ikerg:
In my case if background connection is not enabled the AA does not connect...only activating the background connection connects but I don't want Zlink each time i start the car.

I can connect in hd with version 5.2.47
[MTCD Android Head Units General] ikerg:
The channel is just the platform or vendor....there are different t android headunits with common platforms and Zlink is prepared for all of them but you can not mix them.

I don't knot where did you get the Zlink app you installed but you need a Zlink version for your platform.....

The best and easiest way is to find a firmware update for your unit and install it.

This thread is under mtcd android units (mtcd platform)....and for sure your unit IS NOT a Mtcd unit
[MTCD Android Head Units General] moskito280374:
I dont need the background connection as well. My main usage is the HU itself...AA I just want to have when I need it. So like you it should not start with the car :)

Where did you get version 5.2.47? Mine is 5.2.14...Is there any download link somewhere?
[MTCD Android Head Units General] ikerg:
No...i can get it from the Rom....but I don't think it will work for you due to the channel. Can you share a picture of the "about" screen of Zlink?

Hello everyone Faced with such a disaster: zlink is disabled in android settings without the ability to enable (transparent button). Contacted the seller, he has no idea how to solve this problem, so he is only engaged in buying and selling, and no more.

If so...and you don't know how to solve it....the only thing is to reflash your current ROM or new update. Ask your seller/manufacturer for an upgrade

Hi all,

I recently installed the PX6 and so far it's been great. Everything seems to work as it should, carplay and android auto work excellent with ZLink. However I found an issue the could be user error or a bug or a miss configuration but not able to figure it out. I can get wireless android auto running and working great on my S22. Now if I have no music or anything playing and I hit the microphone and ask Google something like "what's 1 + 1" it'll give me the answer then the audio app I had up previously will autostart. I don't want the audio to start, I had it stopped for a reason and don't want it to start. How do I fix this? I turned off autostart in Android auto and the music player ( in this case iheartradio). I checked with another car and it works like it supposed to just this doesn't. Any help is appreciated.

[MTCD Android Head Units General] AlessandroBorroni88:
PAYING $5 through PayPal if you help me fix this. I have used Zlink for years in my PX5/Android 9 Isudar but the app got deleted. Now, I can’t get it to work again, either it does not install or (latest) versions install but give me a “miss match error”.

I did a factor reset and deleted the previous Zlink folder with Root Explorer giving root with Malayk mod. Still not working. PLEASE HELP!!
[MTCD Android Head Units General] graycorgi:
I was a little confused by lots of mention of "install" and "uninstall" in this thread so I will write what worked perfectly for me. You must root first, which I did following the thread for rooting Android 10 MTCD devices.

1: Obtain the entire zlink folder from a newer rom, not just apk (there are subfolders with updated files too). For me that was /odm/bundled_persist-app/zlink-wla-a-hengchangtong-release-v4.0.41.11_jg from Android 11 HA3 20220706 version.

2: Put this on a flash drive and plug the drive into the USB port of the MTCD/E unit who's zlink you're trying to update. In my case, the destination unit was running Android 10 HCT4 20211009 (last version without major Bluetooth problems for me, and also has day/night mode on system UI)

3: Using a file explorer with root permissions such as MiXplorer, browse to your /odm/bundled_persist-app/ and copy the zlink-wla-a-hengchangtong-release-<oldversion> folder currently there to your flash drive (to back it up) and then delete it from /odm/bundled_persist-app/

4: Copy the new zlink-wla-a-hengchangtong-release-<newversion> folder that you put on your flash drive earlier into /odm/bundled_persist-app/

5: Reboot and enjoy new zlink version!

That's it. No need to uninstall or install any apks. No need to rename anything or even keep the old zlink folder there. It somehow knows where to find zlink even though the new folder has a different name due to the newer version number.

Since the full ROM image files including ZLink are provided by Dasaita for free for anyone on the Internet to download, here is the ZLink 4.0.41.11 and ZLink 4.0.41.14 folders from their image file to save you the trouble:

https://mega.nz/folder/gOdQXJzB#B4iSW89NaZsu6cnKPQnmHA This will only activate on a HCT / Dasaita head unit that was originally licensed for ZLink. I can confirm this version works without the issue where using google assistant causes lower volume afterwards.
[MTCD Android Head Units General] iagobkstar:
Thanks a lot for sharing! That specific bug had been driving me nuts for well over a year... It's good to see that even though Zlink itself is a pretty hacky piece of software, there's ongoing support and development for the app.

After updating, I've also noticed that USB connection to Android Auto is blazing fast, 3-4 seconds in my case, and that the eye care (i.e. blue filter) settings from the phone carry over to Zlink. Both welcome additions.

I cannot say for sure if Wireless AA is better or worse than the previously installed version (I was on 4.0.37), but before it'd work flawlessly like 95% of the time (connection in about 15 seconds) 4% of the time taking about a minute to connect and 1% never connecting and requiring wired connection.

I don't think you had a Dasaita unit....for which MTCd units have version 4.xx. of zlink

Version 5.xxx is for other platforms....in my case "other" platform differntt than MTCd and with sd665 processor.

Can you share the about screen of zlink?
[MTCD Android Head Units General] Asobitai:
i think i have the other platform but ill dump the firmware in case someone else wants it.

currently dumping a different version of the qcom unit going to see if i can find the files there i wouldn't recommend updating your mcu with stuff you find online but extracting apk should be okay.

edit found a version of 5.2.68 does not go into HD

if im on the wrong page please delete my post
[MTCD Android Head Units General] Asobitai:
can i get a dump of your version 5.2.47 the person i get the files from dont have that version and the latest version fails at HD
[MTCD Android Head Units General] ikerg:
1) this thread is for MTCd units...and your unit is not.

2) you can not use a zlink version from different channel (vendor) than the one corresponding to your unit.

3) as this is a MTCd thread here only you can obtain a v4.xx zlink version for the hct channel (which corresponds to MTCd units)

Ask on a thread for your specific unit platform
[MTCD Android Head Units General] Shanzybeatz:
Please help i have an issue with mine i did not realise i could not update it and i deleted it now cant find it any where i can redownloaded it ,tried different zlinks but not working please does anyone know a link
[MTCD Android Head Units General] ikerg:
You will have to ask your seller for a new firmware suitable for your unit....as the zlink app is preinstalled on your fresh firmware.

I don't know what kind of platform do you have on your unit so only the seller and/or manufacturer could help you....or ask on the android head units general forum for help. What I can really say is that your unit is not an MTCd unit.

Hi All. I'm reading about this Tlink and Zlink app that's supposed to give you Apple Carplay and Android Auto, but I guess my question is, can I just install this on any car's Android headunit that doesn't have OEM Android Auto and Apple Carplay? In other words, will these apps (Tlink / Zlink) give me AA and Carplay on my Android headunit, or there are other prerequisites such as specific hardware, firmware, etc.? Would appreciate some clarification! Thanks.
[MTCD Android Head Units General] ikerg:
No..those apps rely on specific hardware to run...they are tied to specific android headubits vendors
[MTCD Android Head Units General] Gulczas31:
Hey, nice post :) I have a question: will it work for me? Do I need to buy a special external adapter for carplay or do I already have one in this equipment? I cannot activate zlink..
[MTCD Android Head Units General] graycorgi:
The zlink files I linked will only work if you are already able to activate zlink. If you can't activate it now, you won't be able to activate it with those files.

You probably need a dongle, I don't know if you have the hardware in the unit but even if you did you'd need to be able to activate it. That's a better question for whoever you bought the radio from. Probably you will need a dongle and won't be able to use zlink.
[MTCD Android Head Units General] Gulczas31:
Thank you for your response.

Doesn't this photo show that there is carplay in my device? I wrote to the seller but for now it's silent..
[MTCD Android Head Units General] graycorgi:
No it doesn't, you can select whatever you want on that list but it doesn't mean the feature is present. Either way, I can't help with activation problems, pretty sure only the seller can do that.
