Hello.

It is possible to solve the problem without resetting the settings?

Decided to upgrade to the latest version firmware from 12/1/2024, only system upgrade, no MCU upgrade, and after this succesful update i can't acces the any of settings menus, can't cange anything.
[Android Head-Units] tomcuta:
Hello,

could you help me with the problem - the radio very often disconects. There is blue diagram on the sreen only (radio still working). If I press the button "Home" the main screen well be visible again. Why does the equipment still diconected?
[Android Head-Units] The-Doc:
That's the front camera, but you don't have a camera connected, so you're seeing "No Signal"
[Android Head-Units] tomcuta:
Thank you. How can I switch off this camera?
[Android Head-Units] The-Doc:
I don't know. I have to manually activate my front camera, or set it to come on for a set period of time after shifting from reverse. If the camera is starting by itself, I assume there's a problem somewhere, but there are far more knowledgeable people here who will have an answer.

I also want Honda...
[Android Head-Units] JSR_FR:
Hey guys ! My unit randomly reboot all the time. I did try a factory reset, update... with no improvement. The seller is sending me a low voltage regulator. Anyone had a similar experience ?
[Android Head-Units] The-Doc:
I saw your post and thought I'd have a go at making a boot animation. I thought 'it can't be that hard'... Well, like most things, it isn't that hard once you learn how to do it, but it took me about 4 hours, including learning actions and batch image processing in Photoshop (insert facepalm smiley).

Anyway, I think I managed it. I don't know if the head unit will work with JPG images, but the PNG format one is ~40 meg, so I've made both PNG and JPG formats.

Can we keep it in xda
[Android Head-Units] PrinceLc:
On both platforms are all Infos and information telegram is only more convenient for live chat
[Android Head-Units] lucky_lucyan:
THANKS!
[Android Head-Units] lucky_lucyan:

[Android Head-Units] The-Doc:
Did you use the PNG or JPG version?
[Android Head-Units] lucky_lucyan:
I put png but jpg also works
[Android Head-Units] The-Doc:
Thanks... That makes for a smaller file size on my next one.
[Android Head-Units] afigienas:
NO ITS NOT. Also there is no info what bands it works on.

It works but only sometimes...[works always if you wait a lot] it works but doesnt work at the same time. and it sNOT realted to LTE bands. i have web radio app, it works, but youtube, and many other doesnt.... i gues web radio uses ip to get stream, while 99% of other apps uses domain name. Thats the problem...when it comes to domain names. Also modem crashes while driving..looks like everytime it connects to new cell it crashes/restarts itself. After that it works (as i said earlier). So if bands would be the problem i would see no signal, not full bars. it works, but it doesnt that the problem. Also as i said to few others: If i once agai read to use my 1400 eur phone as a fking router-i may go crazy! :D

PS Seller said oh use 2024 fw and newest MCU it fixed inverted lcd and lte problems.. yeah right :DD

[Android Head-Units] tmihai20:
After a few months I am quite pleased with my headunit except connecting to OBD2 adapter. I am struggling to connect to OBD2 adapter with my S8 headunit, I even contacted my Hizpo seller on AliExpress. The only thing I have not tried is to start Torque before trying to connect to the adapter. This is shown in the video I got from my seller on AliExpress. It would be mind blowing if it works. I even bought their recommended adapter, I had a very cheap and very old one. I don't mind using their new adapter, it looks better and seems to be better than my old one.
[Android Head-Units] MauriBixio:
If the BT OBD adapter is paired correctly, it works (remember that NOT all OBD adapters work, and to pair with the radio you must change the BT pin of the radio from 0000 to 1234).

Well, but EVEN if it is paired, BT data streaming MUST be open every cold start of the radio, it is NOT automatic.

So for example, after starting the radio, if you launch apps like Torque (which you must first set correctly to use your OBD adapter) this app manages to open the BT data streaming with OBD adapter, and then everything works.

Therefore, apps such as Torque (but there are others, although few, many fail) serve as "triggers" to open communication between BT radio and BT OBD adapter.
[Android Head-Units] PrinceLc:
Carista and OBDeleven works in my S8 I connected both to the android Bluetooth settings so when I start the application Carista or Obdeleven then it connects to the adapter
[Android Head-Units] MauriBixio:
Vgate Icar BT OBD adapter (Simple and Pro) also works correctly (with S8) however you always need an app to run on the radio as a "trigger"...

I can use 3 specific apps (paid) for BMW, together with the radio, and they all do that.

However, Torque app also manages to open communication between radio and OBD BT.

I already showed him that this modem is only able to work on B3 LTE in Europe (and not at all in the US).

[Android Head-Units] delumiron:
Mine also works with the B1. I checked with LTE Discovery
[Android Head-Units] tmihai20:
None of the suggestions worked. The seller asked for a video, I sent them a video. The thing is that I am still on the firmware it had when I bought it (System Version QF001.20230824.202940_v2.69_02 and MCU version QF03.V01.05.20230617.002121). Maybe I should update to a newer system and MCU version, I really don't know. I am waiting for a reply from the seller, they seemed to be quite involved, they replied to all my questions.
[Android Head-Units] itiswitis:
Do you have your phone paired to BT? If so, your OBD BT has to connect and data streaming first. If you have both OBD and your phone paired to BT, phone will always connect first.

To test you can disable BT on your phone and restart unit, so that OBD is first to connect. Once Torque is connected, you can turn on phone BT.

This was supposedly fixed in the Nov 2023 firmware. They included an option (i think it's options 42 and 43) to enable "dual bluetooth". 1. for pairing phone through app, 2. for pairing OBD through "native android" BT paring. When you enable option 42, it will open up the native android bluetooth settings. However, this patch did not work for my head unit, I suspect it's because I'm still on QF01 MCU.
[Android Head-Units] tmihai20:
@itiswitis: yes, my phone is paired and connected through BT. I will try this as well. I don't understand why they don't rely on regular Android BT settings and prefer to use their own implementation that can (and will cause problems, as we already saw). MCU must also be updated to match the version of the system software. Thank you so much for replying, it can help others as well. I knew I would get support from the community, it was another reason I chose this Android headunit.

I would update, I think we can downgrade as long as Android version is the same. I don't believe that they changed Android version to Android 13 with the 2024 updates. It is very easy to change the displayed Android version, some developers of Android firmware are doing it for a long time. Let's see what the seller has to say, I will let everybody know.
[Android Head-Units] alvaroja18:
Hi, How I can change the logo from my S8 ?
[Android Head-Units] 19vik:
I can confirm factory menu code 01010101 will enable all car manufacturers brand boot logos.
[Android Head-Units] alvaroja18:
How I can put these menu code, because in my car only can enter the 8888 code
[Android Head-Units] PrinceLc:
In factory code 01010101 enter then go to the section to change car logo and you see a bunch of logos.
[Android Head-Units] PrinceLc:
Update to January but the latest from 19th OBD connects immediately when paired through the android Bluetooth settings. Android still A10 Fake device test was passing that it's A13 but I talked to the dev and he updated the app and now it shows correct Android version.
[Android Head-Units] alvaroja18:
I try your code 01010101 but no enter to the menu, only accept 8888 code.
[Android Head-Units] 19vik:
and just to know, after first reboot all brand logos will be hidden again. If you want to choose an other again, you have to enter again code 01010101
[Android Head-Units] alvaroja18:
Thank you very much...Now I understand the process 👌
[Android Head-Units] alvaroja18:
Dear friend, can you tell me how to place your own launcher. When I just installed it I had the same one but I changed it for another one and now the same one that you have no longer appears in the options.
[Android Head-Units] alvaroja18:
Some body can help me to confirm if my firmware version is up to day ? I have problems with the 5ghz band hotspot. Somebody has the same problem ?

I have de S8 version (8gb/128)
[Android Head-Units] delumiron:
I had the 06-2023 firmware and I had a problem with Zlink with the 5 Ghz band. It stopped and had big lags. I used it with the 2.4 Ghz band. With the latest firmware of 01-2024 the problem seems to have disappeared. I'll test it better these days.
[Android Head-Units] Barykelo:
Install the latest firmware + MCU. For the firmware, I recommend leaving the item checked - delete user data. You will prevent further problems.

https://autofather.com/s_sjjc
[Android Head-Units] alvaroja18:
Understand, I download the files but I do'nt know if the size of the MCU.bin is correct because only has 47KB and the process pictures show a more big file...🤔
[Android Head-Units] Barykelo:
Yes, the MCU is only 47kB. I forgot, before installing the MCU you will have to enter the code 774411 + OK in the factory setting to enable the change from QF03 to QF05.
[Android Head-Units] MauriBixio:
I still don't seem to have read of anyone who has done (with S8) directly from MCU QF01 to QF05... it would be interesting to know the result.
[Android Head-Units] alvaroja18:
Only before install MCU ? or before to the firmware too ?
[Android Head-Units] PrinceLc:
Before installing MCU
[Android Head-Units] alvaroja18:
I install firmware and MCU to last version but the problem with the 5ghz band persist. What I can do it ?
[Android Head-Units] Barykelo:
I have no idea what the problem could be. It works for me without any problems.
[Android Head-Units] PrinceLc:
No problems with 5Ghz on my S8 I don't know why ?? Try maybe to change Name and Password
[Android Head-Units] itiswitis:
It looks like you're trying to create a hotspot? Does it work on 2.4ghz? Do you have a SIM installed? I've never tried the hotspot function, but maybe it needs an "uplink" to create the hotspot.
[Android Head-Units] delumiron:
Use 2.4Ghz. Nothing changes anyway. When 5ghz is activated for me, the Zlink starts lagging. I use 2.4 Ghz which has a bandwidth speed of 96 Mbit which is more than sufficient.
[Android Head-Units] alvaroja18:
You can share a short video about it (hostpot) in your radio S8 ?
[Android Head-Units] alvaroja18:
I want to use the 5ghz band because in the because in the radio specifications it indicates that that band is used for wireless in Androidauto. The 2.4ghz band works but I think the 5ghz band would give more stability and speed, if it worked well of course.
[Android Head-Units] PrinceLc:
Yes I can I will tomorrow ok
[Android Head-Units] Barykelo:
I would try a full factory reset by entering the code 22558800. Then you will need to set the side buttons (see video) and the car type for the canbus (8888).
[Android Head-Units] alvaroja18:
I do a full factory reset with code 225588 (22558800 no work for me) and wifi/bluetooth reset too but 5ghz band no work yet 🥲
[Android Head-Units] MauriBixio:
With phone hotspot these units work perfectly...with embedded SIM..mmmhhhhh
[Android Head-Units] PrinceLc:
He needs the 5Ghz hotspot for Android Auto also Zlink connection. And yes 5Ghz hotspot from the phone to the radio is better then the 4G connection from the radio.
[Android Head-Units] Barykelo:
is this not working for you?
[Android Head-Units] delumiron:
In my opinion there is an interference problem. The 5 GHz doesn't turn off for me, but it's not stable. It goes from 344 mbit to 96 mbit then to 300. And so Zlink has lag and YMusic's music stops. However, on 2.4 it works perfectly and the bitrate is fixed at 96 mbit/s. I removed the SIM and it seems to work fine. But I prefer to use 4G. However, Android Auto works perfectly on the 2.4Ghz band without any lag.
[Android Head-Units] alvaroja18:
I do it like you show in your video and I can performance a full reset, but de problem with the 5ghz band continue.
[Android Head-Units] alvaroja18:
Oh no....🥲 so my radio has a problem...You can share a screenshot about you firmware and MCU version ??

Can you share a screenshot about your firmware and MCU version, Please.
[Android Head-Units] PrinceLc:
Later I am at work
[Android Head-Units] alvaroja18:
Thank you ...I have the same version
[Android Head-Units] Barykelo:
Write about the problem to the seller.
[Android Head-Units] Barykelo:
Do you have this 10 pin connector plugged in? It has additional antennas for wifi (2.4GHz) and bluetooth. This is the first thing a Chinese will ask you. Of course, this should not affect your problem.
[Android Head-Units] Mr.TT_NZ:
The two wires in that connector are for Bluetooth and for 2.4GHz.

The 5GHz antenna is the little stubby one between the radio antenna connector and the GPS antenna connector. Make sure you have not covered up that stubby antenna with a bunch of your wiring or anything else conductive that could block its signal.
[Android Head-Units] TizSpeedy888:
anyone getting wierd low volume on the January updates decembers fine the radio seems to be the only app thats normal im sure i saw a post about making a bluetooth phone call fixes it for abit but ive not tested it yet ive got the s4

[Android Head-Units] fmcheca:
Hi Barykelo. I like your launcher. How could I install it?
[Android Head-Units] Barykelo:
It is the daily version of this integrated launcher.
[Android Head-Units] alvaroja18:
Let me check how my installation is. Although I made it myself but I don't remember if that cable is connected. I remember well that I did not leave any unconnected.
[Android Head-Units] alvaroja18:
Let me check how my installation is. Although I made it myself and I see these antenna but I never touch because it comes plugged in.
[Android Head-Units] alvaroja18:
He asked me for a short video about it, I sent him the video about the failure and I am waiting for a solution.
[Android Head-Units] alvaroja18:
No I don't have these pin connector, I attach picture about my installation.
[Android Head-Units] alvaroja18:
I already checked and there doesn't seem to be anything that generates interference, in fact I disconnected the GPS antenna, the 4G and the radio antenna, to try the 5GHz band again but the problem remains the same. Also check if the 5G WiFi antenna is well connected but apparently it is integrated because it does not allow it to be removed and reconnected.
[Android Head-Units] PrinceLc:
Did you try to change Name and password?
[Android Head-Units] delumiron:

[Android Head-Units] alvaroja18:

Hm ok then there must be something faulty
[Android Head-Units] delumiron:
HI. I can downgrade firmware and MCU?
[Android Head-Units] Barykelo:
Yes
[Android Head-Units] PrinceLc:
You here music and do you have SIM in the radio ?
[Android Head-Units] delumiron:
Yes, I have the SIM. I removed the SIM and now it's working again
[Android Head-Units] PrinceLc:
You need a new display cable for the black screen issue
[Android Head-Units] delumiron:
And strange, because it worked for more than 15 days without any problems. Yesterday I updated the firmware and MCU and today the problem
[Android Head-Units] PrinceLc:
Was in my case the same when the unit was new
[Android Head-Units] delumiron:
Do you have a link to buy this cable. Or should I ask the seller?
[Android Head-Units] PrinceLc:
First Seller did the same they know it and what cable to send, I got the cable and a new Display for 0,002 €
[Android Head-Units] inscriber:
Today I change the cable but problem is not fxed. you can try of course. my seller send me cable for 0.1$ I sent him this screenshots on first one is LCD Id
[Android Head-Units] delumiron:
Have you changed the cable and it still doesn't work?
[Android Head-Units] inscriber:
yes it still have screen bug :(
[Android Head-Units] delumiron:
Even without a sim card?
[Android Head-Units] PrinceLc:
In my case since I changed this cable no Problems with black screen anymore
[Android Head-Units] itiswitis:
Something is getting lost in translation... You don't need to manually create a hotspot to use wireless android auto. All you need is the bluetooth connection. Wifi will direct connect to your phone via zlink.
[Android Head-Units] inscriber:
black screen issues is only with sim card for me. if I remove it there's no problem.
[Android Head-Units] delumiron:
OK. Thank you
[Android Head-Units] alvaroja18:
I know it is not necessary but the factory configuration comes with the 5GHz band activated by default and that is why I could not connect to the Android Auto system. When trying to find a solution I realized that in the seller's publication it indicated that it used the 5GHz band. 5hgz for android auto, then I saw the problem that in that configuration the host was constantly connecting and disconnecting, then I changed to the 2.4ghz band and the android auto worked, however, the connection is not stable and presents a lot of lag. I have seen how Android Auto works in the 5ghz band and it is more stable than mine. I bought this stereo to have this function working in the most reliable way.
[Android Head-Units] robbe51:
Hello, I have a problem with my QF001 which is installed in a mazda cx5. The sound only comes when I have set the fan control to manual. The bigger problem, however, is that I have a constant, quiet hissing noise in the speakers. The manufacturer then said that I should carry out an MCU update. My current version is: QF03. V01. 06.20230814.002121. The new version is Qf05. V02. 03.20240106.002121. If I want to carry out the update using the upgrade function, the system does not fit the current platform. What can I do now? Unfortunately I don't know what to do next and I hope someone here can help me. Please excuse my bad English, my German is much better. :p

with best regards
[Android Head-Units] PrinceLc:
As factory code 774411 then ok and update MCU again
[Android Head-Units] Mr.TT_NZ:
Robbe51 you have the power control for the amplifier wired to the fan control wire. You need to disconnect from that wire on the 20 pin connector and instead wire it to the 'wire tagged 'ant' on the main power / speaker connector (blue on my unit). The way you have it is at the moment how it used to be before they added the fan control function because there was no spare pins they could use for the fan. This will fix your lack of sound with the fan off.

The hissing sound is probably due to feeding the amplifier inputs from the speaker outputs (if that is how you have it). You could try feeding the amplifier fron the RCA jacks, otherwise you may need a level converter which most car stereo shops should have.
[Android Head-Units] robbe51:
How do I power the amplifier via the cinch sockets? Many thanks for the help. The MCU update already worked.

Is there a way to downgrade ZLINK app to the version from earlier firmware? I know that it's a weird question, but one earlier FW had the ZLINK Carplay with 5x2 rows of icons and I liked that interface a bit better. I'm on the most recent FW and I don't have any problems with it, so I would like to keep it, but just downgrade the ZLINK app. I have extracted the apk file from the earlier FW, but it's not allowing me to install it - "App not installed" - is the result. Is there a way to force it? Maybe via ADB shell?

Hello everyone,

I would like to ask the guys where their cars have a middle front speaker if it is working with this headunit.

I noticed on mine (Corsa D) that it's not working anymore and no, it's not the speaker.

Is there any way to fix it or it's not software related?
[Android Head-Units] tmihai20:
I am coming back with my ODB2 connection issues. I updated my S8 headunit firmware to 2023.11.20 and MCU to QF03.V01.06.20230814.002121. After disconnecting my phone I was able to pair with my ODB2 adapter and use it. I just did not want to use the latest firmware or MCU from 2024. This firmware seems to be good enough for now (but I just installed it). Thank you all for your suggestions and help.

Hi,

My experience with the S7 6gb/128gb unit with Opel front, bought it from Hizpo on Ali.

Changed already the boot logo to a nice Opel emblem and will try to make an animated one like I saw on this thread.

Canbus/steering wheel all work or can be remapped, separate Opel display in my car shows FM station and volume changes.

My only problem is the sleeping mode, sometimes after some hours or night using car again Google related apps crashing or apps installed from Playstore.

Later found the whitelist in factory setting regarding kill or not during sleep mode, but took it off from sleep mode, can be set also with factory settings 8888, so dunno know if that fixes it, maybe will try with 2 hours sleep and then off.

Maybe related that I use mobile hotspot, no 4g card inserted, or apps don't like to be killed and restarted again during sleep/wakeup.

Hizpo is friendly and provided FW updates to me, dated 1228 and 230109, incl. MCU files 1216 and 230103.

Quit easy to check new firmware just by changing the dates in the provided links.

Hope people understand that the MCU.bin file is related to the radio chip, mine has 7708, FW seems the same for all "S" units, see in this thread people using the wrong one.

When do factory reset 22558800, please be noticed that Canbus need to be adjusted again threw factory settings and that you need to remap the plastic buttons on the unit.

Also got other code from Hizpo to wipe data only 22588

WIFI and BT works flawless, no problem with connection.

Like the unit, hopefully it will last long, btw hardly hear my fan, standard delivered microphone that came with the package also works okay and clear.
