Hi everyone!

I have a hizpo s8 8-128GB head unit. My car is a Citroen C5 X7 2008 Tourer. I can't adjust the climate display. With the old Junsun V1Plus 4-64GB head unit it worked fine. I needed the 3 usb, tpms, dvr, flash drive and the sub volume setting, that's why I changed it. I don't know if it's a hardware or software problem. Everything else works fine, the brightness of the display could be a little stronger. The seller doesn't really know or want to help. I've attached pictures. Thanks in advance for your help! Ferenc.
[Android Head-Units] ScorpionSX:
What do you mean by "can't adjust the climate display"? On your photos, the climate controls are below the stereo, so you can control them independetly and you can also see what temperature you have set and where the air is blowing.

Do you mean it's not also showing on the radio screen? Or?
[Android Head-Units] 19vik:
You have two can bus boxes, which one is installed?

Seems like you have selected the wrong one. Something like the canbus box is Simple soft, but you set Raise.
[Android Head-Units] Ferike57:
Yes!

So, whatever I set with the climate buttons, nothing appears on the display below. Fan speed, air flow direction, temperature value, rear window heating, etc.
[Android Head-Units] Ferike57:
The simple soft belongs to the old junsun head unit, it worked with it and the display was good. The Raise came with the hizpo in the package and if it is set to that, all the reasons are there, except the climate display does not work.
[Android Head-Units] Dinocoblue:
Hi all,

I live in Australia and bought this unit from CJ industries. Just wondering if there is a new MCU update for it? Where i could find it? If it exists, what the benefits of updating would give and how one goes about updating this unit? Sorry for all the questions. Also wondering as my unit says android 13 but is actually running android 10 why the makers "lie" by saying its running android 13? Thanks heaps for any and all info.

Cheers.
[Android Head-Units] ScorpionSX:
Well, it is possible that the Raise box simply don't support this on your car. What happens if you change it for the SimpleSoft box and change it in the factory setting?
[Android Head-Units] ScorpionSX:
I'm not 100% sure, but I think this unit that you have is a FYT unit, so it's different than what we're talking about here. There is a separate forum for the FYT units, you may find some answers there ;)

And as for the fake Android...you know, it's chinese, bigger number = better :D

שלום לכולם!

קניתי לאחרונה יחידת ראש של חיזפו דגם s6

והופתעתי לגלות שיש פורום נהדר כזה עם כל כך הרבה תובנות וחידושים על היחידה הזו

יש לי רק שאלה קטנה:

אחד השימושים החשובים שלי במכשיר הוא ביצוע שיחות מהפלאפון דרך בלוטוס והאפליקציה שמובנית במכשיר לשיחות בלוטוס לא נוחה אבל אני לא מצליח להוציא שיחות בלוטוס ביישומי צד שלישי כמו טלפון של גוגל האם יש לכך פיתרון אשמח לשמוע

תודה

Hello everyone!

I recently bought a Hezpo model s6 head unit

And I was surprised to find that there is such a great forum with so much insight and updates on this unit

I just have a small question:

One of my most important uses of the device is to make calls from my cell phone via bluetooth and the application that is built into the device for bluetooth calls is not convenient, but I am unable to make bluetooth calls in third party applications such as a Google phone. Is there a solution for this? I would love to hear

Thanks
[Android Head-Units] Ferike57:
So I do not know.

Can I change the boxes? Is that not a problem? I don't want to ruin the new head unit.
[Android Head-Units] ScorpionSX:
Yes, you can change the boxes. If you take a look at the wiring harness from your previous Junsun unit with SimpleSoft box, you will see that probably all of the wires go to the same pins on the Simple box as they do on the Raise box. For example, black ground wire is on the same place on both wirings, yellow battery wire is on the same place and so on.

So you can just take the SimpleSoft box and plug it to the new stereo, then you have to go to the factory settings menu, put 8888 as code and I think right away the first menu item there is the Canbus settings. Click there and you will see an interface where you can select the brand of the box, then brand and model and year of the car. Confirm the settings, it will take you back to the main menu I think, at this point I also like to restart the unit (slide down from the notifications bar and press the Reboot button) and then when it's booted up, you should see the SimpleSoft box with its parameters in the CarApp settings. And you can try and see if the climate control show something on the screen or not.
[Android Head-Units] ScorpionSX:
Hi,

I don't think you'll be able to use any other 3rd party app for that. But, what I can suggest is, to use Carplay or Android Auto for calling - since you already have some phone connected to the unit, it could be maybe more user-friendly than the stock BT calling app.
[Android Head-Units] Ferike57:
Thanks! I'll try and get back to you!
[Android Head-Units] shlomo128:
Thank you for your response, but I prefer through the unit itself and not through Android Auto. In the past I had a Johnson unit and a third party worked for me there, I will try to look for other solutions
[Android Head-Units] ScorpionSX:
Understand. To be honest I mostly just receive the calls when I'm in the car, so it's only a matter of pressing the one button the answer, so I don't think too much about it, so maybe there is a way, but if it's not working directly with an app that's designed for it (as you mentioned Google Phone), then I don't give it much hopes.
[Android Head-Units] Serruxo:
Hi,

Regarding the pinout and the cables you are using with you 12v AC power adapter:

In addition to G2+G3, do you have any other cable connected of the rear pinout (G1...G16)? I guess you will have G1 to ground GND (negative) and G2+G3 to power (positive).

And for forcing the upgrade I guess you only are using your G6 (KEY2 / SWC1) cable... Is there any other necessary to connect to the power adapter to do tests? The rest of cables are to air, without connecting anywhere. It is right?

Thanks in advance.

I can not find if there is a fix to stop the cooling fan from constantly running. It can be 10 degrees fahrenheit out and it will still be running. If I go into the fan app and switch to manual and then back to auto it will shut off briefly, then resume to full speed. I replaced it with the Sunon hoping to make it quite but it is still audible. Any fixes out there?

It shouldn't, It has the effect of transmitting the steering angle to the dynamic lines. Maybe there's something wrong with your settings?
[Android Head-Units] boberek966:
Sorry, everything was done by the website's automatic translator. The problem is the lack of image despite the new camera and cable, that's why I'm asking about the Canbus module.The problem appeared half a year after installation. Replacing the camera and cables does not change anything. Resetting to factory settings also has no effect. Constant "no signal" message. After changing to forward driving, a temporary reset of the unit.
[Android Head-Units] Maferto:
This also happens to me in a Renault Captur, suddenly, the screen showed a "No signal" message, I put the car's original screen, and everything worked fine, I ordered some new cables and the new canbus, let's see if that too I can solve the fact that the original sensors do not make sound.

Hi, does anyone knows how to change launcher? Not to any of those crappy ones that chinese created but from Google play store? I downloaded launcher but looks like chinsese did something and setting of default laucher is not saved. Their launchers are total crap. 1/3 of sceen used to show that car is driving?? with inaccurate speed reading..thanks i dont need it.

Also maybe someone have Jeep Renegade with S4-8 unit? My jeep going crazy with this unit.. always getting random errors, random systems stops working and all related to safety.

Also do you also get random 4g loss? Not to mention that it shows that connected to 4g data but i almos always have to wait like 10minutes so internet to start working!

PS using newest versions of everything from MEGA share some good guy shared here.
[Android Head-Units] lucky_lucyan:
and I talked to them to give me more options to change the launcher and they gave me the latest software version, they said there are more options. the software version is 2024.01

I don't think there are any other options
[Android Head-Units] afigienas:
yeah i already on newest version all launcher the same. GPS is going crazy, shows im driving 5k/h sometimes 35km/h when car is not even started... :) And they show this in 1/3 of whole screen. Who needs it? who needs speed in audio unit while we have speed in dashboard? Also this speed is from gps, not can bus. And unit have terrible gps. signal is not bad still in green but i think internal gps is crap. Anyway i've ordered adapter-cable to connect to original GPS antenna, not that crap that came with unit.

I think they use some config file to prevent launcher change. Or we could change it if we put APK file with he same name as theirs. We of course i think will lose open doors notifications (popups), or climate control, but i dont use that anyway, so i would lose nothing and will gaina alot to have other launcher.

Anyone have tried MCU update QF05.V02.03.20240106.002121 ?? I see there is upload in MEGA share. but QF05... never been before so im afraid to try :)
[Android Head-Units] XDC34M:
look for gps tweak, first page, so you dont use chinese satellites.

I am using original car GPS antenna, never had any issues, getting position fix within seconds after starting car, speed more accurate than speedometer in gauge cluster
[Android Head-Units] afigienas:
I already applied it. It tweaks nothing (IMO). satellite fix have nothing to do with url. (also IMO) I didnt see any change in speed of lock. and speed jumps in GPS app that comes with unit... WAZE shows speed while standing too.. Accuracy was showing to me 2meters at best. In europe we use GALILEO satellites...and galileo also was included in default selection in settings (information tab), so maybe this is the cause i did not see any change that is not just a placebo :) It does not fix in seconds..at least have to wait 30seks. which is ok too...but.. driving it sometimes jumps around the map... maps starts zooming, zooming out... (i think accuracy changes causes zoomout in Waze), looks more like crappy gps chip that fails at data decoding than settings.
[Android Head-Units] XDC34M:
Galileo satellites are not limited to europe.

Either your chip is faulty or your signal reception weak. Again, no problems here, so its not an inherently crappy gps chip, just (maybe) your crappy device and/or antenna
[Android Head-Units] 19vik:
I can confirm, your signal reception is weak. I had same issues at the beginning using gps antenna delivered with HU, need 5 minutes to gain position, in Waze jump on map during driving, speed jump too even when the car is not moving. For me, that antenna work only out the window outside the car (I have heated windshield).

I bought an adapter and connected to original shark fin antenna of the car. From then, gain position in few seconds, minimum 10, usually 15-20 satellites in use, accuracy 1-2m, speed accurate, in town even with high buildings around. No tweaks from first page applied, no issue about time clock in notification bar.
[Android Head-Units] Yevhen7788:
Tell me a good GPS antenna for our device. no factory antenna

Are all the button on the screen functional? Like the auto, sync

Are all your buttons on the screen functional? Like the Auto button, sync, power, front heating, rear heating, outside air, etc?
[Android Head-Units] Vampire_Dracula:
Relying on the LTE module in Europe or the US is a mistake. It is designed for the Chinese spectrum.

The only compatible band is B3 (1800Mhz) while in Europe many additional bands are used, low frequency bands with better coverage (see below the example for Germany, similar to most Europe, next to our chinese LTE modem specs)

Your regular phone in hotspot mode will clearly perform better.

Nice, I see that actions on the hard buttons below are reflected on the HU screen. What about the other way around? Is pressing the screen buttons having the same effect?

Hi

As was published here

https://xdaforums.com/t/recovery-ac...s-7862-headunits-no-fyt.4538107/post-89281305

the method to unbrick the device uses a .pac file named, exactly

QF001_jitu_20230109_user_carletter_v3.08.pac

I am trying to find the pac file for Hizpo S8 G4 with 8Gb/128Gb DSP BU32107 and TDA7708. The mentioned file it is very outdated and there are no warranties works with my exactly Hipzo model.

Anyone knows any kind of repository for these pac files?

Where I can find autostart settings? To give applications permission to turn on on start?

What can I do if google map audio stops radio and I have to back to radio again?
[Android Head-Units] BenJ_54:
I had to use this pack to unlock my car radio (Hizpo S8 - 4G) because I couldn't access Android recovery mode no matter what I did.

It unbricks the car stereo. Then you can update the firmware ("update.zip") and the MCU ("mcu.bin").

My current configuration is :

- System: QF001.20231110.185622_V2.84_02

- MCU: QF03.V01.06.20230814.002121

It seems to work fine.

If anyone has a more recent version of the pack, I'm interested.

QF001_jitu_20230109_user_carletter_v3.08.pac
[Android Head-Units] Serruxo:
I was able to unbrick my device but .pac file does not match with my hardware specs.

Now Storage Information shows

DDR: 6.00 Gb !!!!!!!!

instead the original

DDR: 8.00 Gb.

Flash memory is right 128 Gb.

Several hard / factory resets done without success.

Updated to latest firmware and MCU (Januray 2024):

- System: QF001.20240112.001357_v2.93_02

- MCU: QF05.V02.03.20240106.002121 (required enter 774411 code previously to disable MCU verification -for replacing from QF03 with QF05-)

- DSP: BU32107

- RADIO: TDA7708

- CPU: UIS7862S

Definitely I think a specific stock rom .pac file is required for 8 Gb / 128 Gb S8 4G Model. So that QF001_jitu_20230109_user_carletter_v3.08.pac stock rom file would not valid because you will loose 2 Gb of RAM.

Would be nice to find the newest .pac file for that model or somebody could extract and share the one from its device.
[Android Head-Units] XDC34M:
The SoC only supports a maximum of 6gb ram anyways, so it couldnt have been real, fully featured 8gb ram. So I wouldnt bother too much about it if you cant fix it right away.

But I understand your concern. The more recovery options and .pac files we have the better
[Android Head-Units] Serruxo:
Thanks for your reply. Coud you provide more details about the word "SoC"? What do you mean exactly?

Before the brick, radio showed 8 Gb of RAM as factory. Now after unbricking and all I explained only shows 6 Gb. I think the reason would be in the only existing stock .poc file.

Obviously I am not able to confirm if that RAM 8 Gb was a fake. It would be a very bad news regarding the brand. The same issue is happening with other newest radios (other vendors) that are sold as 6 Gb and only have 4 Gb reported by apps for hardware info detection.

EDIT: I you meant the maximum supported memory for the UNISOC UIS7862S processor of this radio is not 8 Gb, you could be right, if table shown in this page https://gadgetversus.com/processor/unisoc-uis7862s-vs-unisoc-uis7862/ is true.

There are two versions: UIS7862 and UIS7862S, and both seems to support 6 Gb of maximum memory.

Then... the 8 Gb of RAM might be fake or not totally real. Maybe 6 Gb of real RAM plus 2 Gb of a kind of swap memory. It would be very serious if were true because devices would have been sold as 8 Gb without warning that this amount is not totally real but might simulated. Thanks for the point.
[Android Head-Units] BenJ_54:
I confirm what you're saying. I'm happy to have brought my car radio back to life with this procedure (indeed, the only one solution for me), but I also note that the system only recognizes 6Gb instead of the initial 8Gb of my Hizpo S8 !!!

I hope someone can help us, probably with a new pac file ...
[Android Head-Units] BenJ_54:
Maybe there's a magic trick or maybe it's a fake ?
[Android Head-Units] XDC34M:
Yes the Unisoc UIS7862 in our units was supposed to only support 6gb of RAM, that's why I only bought the S7.

But now after doing some digging to find a source again, it looks like nowadays they might very well support full 8gb of ram after all.

According to users here on xda (1) and the manufacturer Website (2) although that one also includes the UIS7862ST, which isn't used in our units:

1:

8GB + 128GB Joying units (and others)

So I ordered a UIS7862-based 9" screen for my wife's RAV4, as it supposedly has CANBUS support, which the 8" Qualcomm Snapdragon 625-based unit I have installed apparently does not. I've gone 'round and 'round with Joying tech support, they...

[Android Head-Units] chadoe:
7862S supports up to 8GB according to the info on unisoc website https://www.unisoc.com/en_us/home/TQCDZ-A7862-1-0

Which doesn't mean they didn't fake it as they are faking more things but it should support it.

Got a S5 myself because 4GB is plenty for anything you want to do on a car radio.
[Android Head-Units] BenJ_54:
Good news. Maybe we'll be lucky enough to get our 8 Gb back then...

I've tried various firmware ("update.zip") and MCU ("mcu.bin") updates. Nothing works. The only hope, I think, is to recover a more recent pac file adapted to the S8.
[Android Head-Units] Serruxo:
Please note you are might refering A7862 that could be a different variant from UIS7862S that comes with Hizpo S8 G4 8/128.

Anyway, the original problem I think is in this case, that .pac file, the only one existing now to unbrick the device, maybe is not valid as stock rom for unbricking the currently newest models for Hizpo S8 G4 with 8/128 (DSP: BU32107 - RADIO: TDA7708). So the right .pac file would be required.

Thanks for the help.
[Android Head-Units] Serruxo:
As I had posted I had installed the more recent files from January 2024.

There should be an app to dump a stock rom from a device creating that pac file, but I am pretty sure that only Jitu brand knows how to do it and have the tools. They might be not interested in sharing this internal enginieering procedure.
[Android Head-Units] XDC34M:
In the telegram group there is someone who connected it to a PC and dumped the rom, it didn't sound very complicated.

So theoraticaly we could dump every version and create our own pac files, if we can find someone willing for each hardware version
[Android Head-Units] Serruxo:
Thanks for the info.

Obviously that dump should be done after reseting to default factory to avoid sharing any personal or configuration data. I think It could be a hard effort to someone who would want share this .pac file.

However maybe I wrong and configuration or personal data is saved on a different memory address. I am not expert how these devices allocate the firmware / operating system or data in the ROM. It could be interesting to study all this things.
