[Android Head-Units] Stormbringer!:
for future reference this worked for me:

I installed the adb utilities on a laptop that is on the same network as the car stereo.

Found the IP of the unit (several ways to do this).

In factory settings menu: Activate developer mode: 114477

enable USB debugging in developer mode

from laptop:

adb connect IPADDRESSOFHEADUNIT:9876

adb shell wm density 240
[Android Head-Units] MauriBixio:
Probably the possible DPI densities are these:

160; 240; 320; 480; 640;

However, changing the density of the screen compared to the previous one could also change the size of icons, text, images, etc. of some Apps, perhaps not making them work or display correctly.
[Android Head-Units] Stormbringer!:
This makes sense and what I wanted, larger "everything" since text, icons and buttons were a bit small. it looks like my older head unit (in another car) now which is set to 240 as well. Thanks for the warning, in my case seems to be working as expected.

Help needed! The device is S8, 8/128, 10.33in, currently the latest firmware and MCU, car is Peugeot 508RXH. From day one voice guidance stopped announcing after some time. Reset, everything OK, especially when Navradio is on losing voice is sooner. Now, the default launcher; default radio, various nav (igo, sygic, waze...), topaz uninstalled. I know from previous posts it's BT-related, but is there any solution. Or should I use a big hammer and solve it for good. The same situation is with Android auto and waze/maps through AA. Will be grateful for a solution. Thnx.

I bought the hizpo s8 1600x720. I was having issues with it taking a very long time to boot. I contacted hizpo on AE and they send me a new firmware. After I installed it I no longer have the volume slider on the left side of the screen. Since I have no physical buttons I cannot turn the volume up or down. Any idea how to enable the volume slider or could it be missing from the firmware they send me?
[Android Head-Units] Barykelo:
You have to do a total factory reset with the code 22558800.
[Android Head-Units] mad212:
Factory reset then install firmware or factory reset after installing firmware? I did a factory reset after firmware and after it restarted still no volume slider and now my touch is all messed up. I have to use a mouse because my touches are way off
[Android Head-Units] Barykelo:
Perform a factory reset with the code 22558800 and then calibrate the display by holding five fingers on the display.
[Android Head-Units] mad212:
Thanks! Touch screen is working now. Still no volume slider. Maybe it's in the settings somewhere. I am using a digital to analog converter and using the optical output for sound to my amplifier but Im not getting any sound after the new firmware. I plugged into the audio out outputs and I get sound. Do you know if there a setting to turn on/off the optical output? Also the keyboard doesn't popup and I can't find android keyboard settings. I can't enter WiFi password.

Edit: found the optical output. Fiber Coax in General - Settings. Still can't get keyboard to pop up.
[Android Head-Units] Barykelo:
Did you reset with code 22558800?
[Android Head-Units] mad212:
I thought I did but I went ahead and did it again and now my keyboard works. Still no volume slider though.
[Android Head-Units] Barykelo:
You will need to ask the seller for a display parameter file (display driver). I do share four variants of this driver here on the forum, but I have no confirmation that it would work with your screen and you could end up with a black screen.
[Android Head-Units] Barykelo:
Also check in the settings if you have this function turned on. I have an 11.5 inch 2000x1200p display and I have this side panel item in the settings.
[Android Head-Units] mad212:
I don't see side panel in settings. Which settings screen is it on?

I too have a black screened unit, made a usb drive mistake. I found the stickers, one outside, one under a small cover (4 screws). Can anyone help me with the right file to fix my unit?

realized I’m a dunderhead who forgot to specify the head unit. A S8 uis 7862s bu32107efv dsp, 8gb 128 for a 2015 Ford Fiesta with the correct canbus box, actually got it working before I mixed up the usb drive for backing up with the new firmware one, so now black screen- it did occasionally play the three preloaded songs.
[Android Head-Units] cnwscion:
Hi all! I cannot get my HU to recognize USB at all.

- k706 uis7862 qf001 s2 4x32 with DSP

- 20240410 v3.84

- All three connectors provide low voltage power (power led on headphones turns on when connected to any of the three usb) but no phone charger power

- USB settings set to file transfer (tried others with no recognition either)

- USB debugging enabled

- multiple cables and ports tested

- ADB devices cmd returns nothing

I updated the firmware obviously so I was able to get USB to work then.

If it's a firmware issue, can't even revert without USB. And my understanding is ADB wireless can't be configured without initially connect USB. Any help is really appreciated!
[Android Head-Units] Barykelo:
What about factory reset 22558800?
[Android Head-Units] cnwscion:
It's working! I only did 225588 reset. Thank you @Barykelo !!
[Android Head-Units] cleverdicky:
Talking of themes, has anyone made any progress customizing for these units?

I've played with a few from launchers to carwebguru. All seem capable but just cant get the look / style I'm after. Some like CWG are slightly customizable. But I think you need to drop a few tabs to figure out how?? And still stuck with the fixed style. I just dont want stupid little animated cars, or silly swiss watches, or speed clocks from a demented alien spaceship.

Strangely, there are similar spec 7862 chinese headunits using exactly the theme Id like but only the dash top, skinny lcd type. Does anyone here have one ?

https://www.aliexpress.com/i/3256806225186653.html?gatewayAdapt=4itemAdapt

I also found a forum talking about overlays with some brilliant graphics and such, which then points to DISCORD, which lost me completely.

I guess no new themed custom roms on the horizon yet :cry:
[Android Head-Units] nomad_fsoak:
Recently I found MCM channel on Youtube, and he shared few themes/launchers that work with our units. I will test them soon , but at the moment for me the best one is the "movable cell" one.

Link to the files:

Lanzadores QF001 - Google Drive

drive.google.com

You can check them out on his videos:
[Android Head-Units] cleverdicky:
Not sure which is the movable cell one, but apart from the cwg icon, they all look like the stock launchers. The video is in a language I dont understand, so wasnt much use to me. Thanks anyway.

However scrolling down I did find one that looked very interesting. It had the same model car as mine and showed off a nice themed launcher I havent seen before. Looks very interesting.

hello everyone, how come the cpu temperature is always 80 degrees despite having the fan on?

I have S8 version

https://a.aliexpress.com/_EwYiX7V
[Android Head-Units] cnwscion:
So USB memory stick is working but K706 and Windows (tried win8 and 11) don't connect.

- adb server starts fine but shows no devices listed

- USB is A to A

- multiple cables tested and ports

- Latest Google ADB Interface drivers installed (though code 10 - and I did disable driver security on startup)

- firmware and MCU current

- usb debugging enabled and default set to "File Transfer"

- I cannot locate the USB "host" verses "device" menu in dev options and it's not under the right hand corner as I have read.

Thoughts?
[Android Head-Units] MauriBixio:
- Install "Remote ADB Shell" apk from Google PlayStore on your phone.

- Open hotspot on phone and connect the head unit to it.

- Run "Remote ADB Shell" on phone and enter the ip of your head unit (port 9876).
[Android Head-Units] nomad_fsoak:
It's the one in the beginning of the video (where there are 2 windows with car speed).

It can be reorganized (you select the windows order and partly what is displayed in them).

I've tested it shortly today and it suits me, mainly because of possible windows reorganization and that the picture-in-picture window is bigger than the one in stock launchers.

Videos are in spanish language but you can turn subtitles on.

Here is another one with this launcher:

And the DARK TUNNEL launcher is the one that looks like dash in new Audi/VW cars (2 round elements on sides and a car in middle)

Hello, I have a question. I have a hizpo s8 7862 in a Mercedes Viano, when I installed it becomes with sleep mode by default. I search a bit and found in general options the sleep mode parameter was set in 7 days. I change it to "no sleep" and works fine. Now I want to change the parameter to sleep 2 hours but it don' t change, every time I cut ignition and turn the key to ignition again, the unit boot from start, loading the logo and the boot animation. Am I doing something wrong?
[Android Head-Units] cnwscion:

Hello friends, yesterday I updated my radio according to the instructions and I have no major problems!! thanks for that!!

Now I have a problem that occurs randomly.

- When running Waze, the application indicates that it does not have GPS.

- When checking the Waze permissions, everything is OK.

- When checking GPS TEST everything is ok!

- I check Waze and it randomly connects to GPS, if I go through a tunnel and I EFFECTIVELY lose the signal, when I leave the tunnel it DOES NOT reconnect.

-Change GPS antenna, everything remains the same.

What should I check more? disable all battery savings and consumption optimizations.

thank you!
[Android Head-Units] Barykelo:
Probably not related to this, but did you do the GPS fix via code 5544?
[Android Head-Units] tobilindo123:
I did it, I changed only the option that was in GPS, Baidu.... to GPS, Glonass... I don't remember exactly what those items said...

Should I change something else?

What is observed on the device is as if the radio saw the satellites, but did not tell Waze that they were available... the strange thing is that all permissions are always enabled.

Good evening to the forum, I have a problem with the GPS, bad signal, I have tried everything
[Android Head-Units] tobilindo123:
In the three points, left side above, you can try the CLEAR AND UPDATE option
[Android Head-Units] bilpat:
I will try it
[Android Head-Units] bilpat:
I did it, nothing changed
[Android Head-Units] chadoe:
Things to try if you haven't already:

-make sure you're in an open space, not in garage/carport/any roof

-move receiver all the way to the front against the window

-turn the receiver upside down

-do the GPS tweak from the first post

-open a window and hold the receiver outside, if the signal still doesn't improve there is probably something wrong with it. If it does improve something in the car is blocking the signal, maybe front window heating, try moving it to the rear window if it can make it that far.
[Android Head-Units] bilpat:
Good evening, no, the car is not in a garage

I went outside the antenna from the window, the signal is stronger but not good, I think it's a bad antenna

Well, I know it’s definitely a display driver and/or display setting. The screen isn’t dead, but that grey looks kinda a little bit staticy but not. The last image it showed was 90 degrees out of alignment and so was the touch response. Is there anyway to factory reset without punching in the code? I tried all 4 drivers in the lcd zip pack, with no success. Attempted the key 2 to ground wire method without success. Right now, I’m debating getting a replacement touch screen that might actually be listed and have drivers , or has the alignment I have now. Currently a 9.7 mounted vertical. Any thoughts? Suggestions? The images are basically the info I have, its missing the correct sticker for the display.

If this display driver is not working, please ask your dealer.

Both items are for automatic installation, so QF to flash drive and insert into USB.
[Android Head-Units] Hamhawk:
Thank you. That brought it back to life! It’s the wrong orientation but that’s not difficult to resolve.

My dealer is not an option, as you can see, its rooted, something it arrived with, and the dealer kept wanting me to send it to New Jersey or Germany at my own expense, instead of even attempting to work with me, instead promising me a smaller 9” Model of unknown specs after they got this one. Thankfuly Ali Express said they were refunding me and told me to keep this as a gift. Of course Ali Express reneged , so I’m making them explain that to PayPal as I kept the chat log.

But many thanks, my current factory radio drains my battery because it never turns off, even with no key in the car, it’ll happy play music until the car dies. This one used less power and has a sleep function!

Hello! After installing the latest firmware, launchers are not available, and the native launcher is very bad, it also cannot open navigation in the second window, this is very inconvenient! Who solved the problem with launchers? I apologize right away, I do not ask for comments from those who do not change the firmware, do not change because there will be trouble! On the penultimate firmware, navigation began to glitch very badly, very often Gps did not work at all! Changing the firmware solved this problem, but the launchers are not available...
[Android Head-Units] alee30:
hello friend,

What is the explanation for the high CPU temperature?

i have S8 version
[Android Head-Units] Elrathias:
Probably russian GPS jamming if you are in central europe or anywhere even remotely close to Ukraine.
[Android Head-Units] Aaantonn:
Two reasons, the first is there is no contact with the antenna, a wire in my antenna somehow came off, until I took the antenna apart and saw that the navigation was missing. The second reason is the penultimate update of the firmware, GPS did not work on it at all from time to time, I had to install a new firmware, but the latest firmware is crap in other questions. There is no conspiracy) In Ukraine everyone uses GPS and that’s how it works))
[Android Head-Units] Elrathias:
Wiring is done wrong if this is the case, the unit gets power but no IGNITION ergo cannot trigger the sleep timer correctly.
[Android Head-Units] Aaantonn:
Please tell me how to replace the Launcher? I downloaded the launcher, launched it, it requested all requests, I allowed everything, set it as the initial screen, but still it returns to the native launcher page.

[Android Head-Units] Barykelo:
If you don't see any launcher, something is wrong (if you don't have the firmware from 10.4.2024, it had a menu of launchers only in factory settings). The only help will be a factory reset.

I have tried to restore factory settings and it is still the same.

Today I installed this one, before it I had it since March, which also worked fine. So far everything is working, I double-checked it, only when flashing it I had to delete all user data, because the launchers did not work without deletion.

After the purchase, I encountered the same problem, the seller advised me to set the sleep mode to 3 days or 7 days, I don’t remember exactly. The seller immediately said that the other modes do not work correctly. But to be honest, I don’t remember how many days I need to set it... But the point is that only one mode works here.

I'm using HIZPO S6 4G LTE model.

When turning on the android unit every time, My smartphone connects to the android unit via bluetooth.

But the music does not play automatically, and I should launch 'Bluetooth Music' app.

In the 'Bluetooth Music' app, after clicking play button, then I can listen bluetooth music via my smartphone.

Is there any method to play bluetooth music automatically after connecting bluetooth, not to manually launch 'Bluetooth Music' app and click play button?
