Firmware 819

I got an updated firmware today.

look here:

Firmware 819
[Android Head-Units] Gyovany96:
Did you noticed any new so far?
[Android Head-Units] duboffik:
You can use usb-mouse. It's a simple way
[Android Head-Units] MasterOfLight:
not really. but I didn't try that much. I reinstalled everything, reconnect the SIM slot and did just a quick test. I will do more later today
[Android Head-Units] hsi1:
thank you!

I replaced the touch screen from j70010 XF to J70010, but it doesn't work. Please prompt if there are settings (/etc/.. or others) in android that are responsible for the touch screen?
[Android Head-Units] Gyovany96:
Tried to update and it failed (with/without CheckSum).. First time I saw the recovery, glad I didn't bricky HU tho! Ossuret S5 QF01

P.S. Maybe this update is exclusively for QF03? If others tries to update let us know.

Does anyone has a problem that cant independently change volume for navigation and music? Even though i have other volume for calls, music and navigation all have the same volume and it is very annoying especially when using google maps and hearing music at the same time.
[Android Head-Units] marioti:
Yes, about this issue i was talking about long time ago. Nav volume seting just not work since i remember. Radio volume is lower as the whole rest, and using it with navi like google, is just annoying.

As far as I know, there is no app which can set volume separate in this HU because volume control is locked by hu soft
[Android Head-Units] snaker12:
I am very curious why this is not one of the most important issues in every single user of this device!!
[Android Head-Units] Gyovany96:
I redownloaded 819 update and it worked! I don't what went wrong last time, I've done same steps.. anyway..

For some reason Zlink app is not there no matter what I do. Can someone upload the Zlink apk from latest 819?

Yes, it just doesn't appear (it's not installed basically, I've checked)
[Android Head-Units] Gyovany96:
It seems like the stock one they offer, doesn't it? You actually replaced it with this one and is better than stock?
[Android Head-Units] Jeka1400:
Yes, I installed this antenna for myself and at this price I am very satisfied. It differs from the standard antenna from the kit. There are even more powerful, but the price is higher.

https://fr.aliexpress.com/item/1005001795979639.html?gatewayAdapt=glo2fra
[Android Head-Units] Gyovany96:
I see the store specific is Antennas. I'll explorer it, see what I find thanks!

Later Edit:

@Jeka1400 Found some 2in1 LTE+GPS antenna, tempted to test this one although I don't know if the LTE antenna should be separated from GPS due to frequency interfering

[Android Head-Units] marioti:
My oem fin antenna have GPS, lte, and AUX heating receiver, so I gues there are no significant interferences
[Android Head-Units] marioti:
I was count to navradio+ which is working now for our HU (and there is no other alternatives for stock radio app) but it still have some issues and don't allow to change the volume. Work is in progress, so maybe in a future
[Android Head-Units] Astralech:
This is how the antenna from the HU set looks like, you can't make it cheaper.
[Android Head-Units] Gyovany96:
I've ordered an monster of Antenna with centimeters accuracy. This one should have full signal even in tornados 🤞

[Android Head-Units] Astralech:
What is the supply voltage? Our HU have 3.5V on the GPS antenna socket.
[Android Head-Units] Gyovany96:
Doesn't specify..

Later Edit: Found it on other store 3-5V. The only difference is that this one doesn't have all the bands like the one I ordered, but it should be the same

[Android Head-Units] Aaantonn:
Hi. Tell me if it is possible to install MCU: QF03. instead of QF01.?

the seller sent me this version, but it does not fit, that's what it says

The MCU update file is not suitable for the current platform. Current MCU Version: QF01.V 01.73.20230207.002121 Updated version of MCU:QF03.V01.05.20230617.002121

When replacing the latest firmware, namely version 20230714, the radio did not turn on several times, I had to remove the battery terminal and reboot it so that it would turn on! I didn't dare to press the restart button on the tape recorder, so as not to delete all the data.

If someone faced this problem, tell me what to do. Thank you.

Hi

Got problem, i did something With screen

In my opinion, I turned off the calibration or, I connected it incorrectly, so that the screen stopped responding from the seller, I got a new screen and 99% exclude it

Is there a person willing to explain to me how to bypass the calibration (5 fingers and most likely the keyboard mouse does not work)

Or wipe the system to factory or upgrade to pure android 12

This is a glitch of the firmware itself. Recently, the volume of the navigator turned on once, as I set it to 1, and I could adjust the music as I wanted, regardless of navigation. But this pleasure lasted about an hour, until the car turned off! As it turned itself on, so it turned itself off (

[Android Head-Units] marioti:
easy. Change name of the main file to update_auto.zip, and put it to folder named auto, and this put to folder named QF. So it should be QF/auto/update_auto.zip

Whole folder QF, put on to penrtive and plug to usb, it should start automatically

Hi guys can you help me? I sent the stereo back for a return to the Hizpo Provided address. The stereo was delivered to the warehouse on August 15th, the seller Hizpo keeps telling me that he can't find the package in the warehouse even though it is delivered to me. I wrote to PayPal to ask for help but they can't do anything because I asked for the return in April, I didn't do it in April because I was hoping that the stereo would be fixed, so April's case closed and they can't do anything more. Can you help me understand why the seller is scamming me by saying they can't find the package and doesn't want to refund me? Thank you 🥲🥲🥲
[Android Head-Units] xdsbx:
Do you have a tracking link ? Just send them a screenshot of it. Had the same problem. I wrot them every day til they refund me full price.

It appears delivered from the link, he keeps saying since August 15th that he can't find my package and doesn't want to refund me, yesterday he also said that I have to find them a copy of who signed for the package upon delivery, which is impossible for me because I I shipped via Poste Italiane to Germany, and Poste Italiane can't help me.

you can always use a G8 pin in main power socket to power the camera. it is always +12 to +14v (not stabilised 12V but all what your alternator give). So the camera have power always when the unit is on.

[Android Head-Units] Aaantonn:
I am writing an answer to my question dedicated to specialists of this topic who do not know how the device works, but only write their guesses, and they confidently think that everyone is stupid!

Changing the MCU version QF01 to the QF03 version is possible and very easy! Changing the version did not negatively affect my system in any way! The screen did not turn on from time to time and the seller himself told me to change the MCU, sent this version and told me how.

To change the version of QF01 to QF03, you need to enter the code 774411 in the factory settings and then download a new MCU. The board version has nothing to do with the MCU ! As I understand it, there will be no more MCU 01 version
[Android Head-Units] Lione2:
Are there any changelog so about MCU ? I'm not sure the seller knows what he speak about
[Android Head-Units] marioti:
Please, do a feedback after some weeks of using QF03. I'm curious, is there'll be any issues

Hi i have a 2k 13 inch screen should be 2000 x 1200 7862s radio but i flash my radio with the wrong flash. now the screen is mirror i have managed to reinstall the original firmware and software but still mirrored. is they any way to fixed this problem
[Android Head-Units] Aaantonn:
And who knows? Here they wrote a dozen times that you can't put 03 instead of 01, the seller asked the technicians, they told him how to do it. What else do you need? You do not change the MCU just like that, but ask the seller. I had a specific problem, at the moment I don't know if it helped or not. But in this topic two days ago, a person asked if it was possible or not, he was answered-what can't you read, they wrote here a hundred times that you can't. Polite people!

If it didn't work, it would be clear right away.
[Android Head-Units] LukasoV:
Hey there, I´m using it for a while - around one week and two things I have noticed: There is a radio playing in the backgroud and Waze on main screen. I´d like to retune the radio to change the broadcast station, so I push the "home" button to minimaze Waze, retune the radio and after that, when I click to "waze" to put it back to the main screen, very short (ca 0,5s) high frequency noise I can listen. Everytime I "maximaze" in this case Waze I can hear that. Is it possible to set the left hardware wheel (not the sound one, the right one I mean) to retune the radio automatically to the closest station with enough strength signal once I tured it? It was set in this way in my older device, so it was not necessay to minimize Waze and it was perfect. Currently is this button set like change only 0,5Hz, so I need to turn a while to catch usable radio station - annoing.

Second thing - paking sensors - I can hear them, but I don´t see any "graphics" on the display how far I am from some obstacle. In my former device, this popped up immediately after reverse gear or push the button. Here nothing, just a sound from sensor system. CanBus is working (fan, temperature, etc,), rear camera in reverse gear as well. (S8, Octavia 2 FL)

Hi. Can any of you help me? I bought a S8 unit from Hizpo a few days ago. After installing the unit, there are only problems. Every now and then I get a black or white screen and I have to restart the device over and over again. Spotify turns off after a few seconds when turned on. From time to time the colors change to negative - they are reversed. I wrote to the seller who instructed me to update the system. I did, but nothing changed. Please help - how can I repair the unit? My soft version is QF001.20230819.183748_v2.68_02, and my MCU is QF03.V01.05.2023.0617.002121.

Hi friend, what is your DSP and Radio version ?
[Android Head-Units] Lubof:
My DSP is BU32107, and my Radio is TDA7708.
[Android Head-Units] LukasoV:
It was in the settings under "Driving car radar" and after turn it on, it´s working in a nice way, thanks for advice. There was also "dark mode" by following of headlights, so when the headlights are on (automatically or manually by light switch), the dark mode of the device is activated - this sounds good, I will test it. Regarding to manage a hardware buttons, I have already ask a seller (Hizpo) and the answer is they will check with the technicians, so I will see.

I had a problem with Fan - no cable for FAN connection delivered. This is repaired for now, but without Fan was a temperature of CPU 86°C, when the Fan is on (automated mode) the temperature is 84°C or 85°C in a minutes. As I have checked some pages, it seem the operational tempeature of UIS 7862 is "within the car’s ambient temperature range of -40°C to 85°C", but even in general regarding to CPU´s - I think it´s really on the edge and a CPU temp is very high. I´m a liitle bit affraid here, becuse the device is quite smooth but by this temperature - I need to ask how long it will stay "smooth".
[Android Head-Units] marioti:
IMO there's a problem with heating transfer. You can have like me, there was gap between cpu and housing.

Need to dissasemby the housing and check, replace to thicker thermopad
[Android Head-Units] LukasoV:
I´m just reading this thread and on page 68 I can see you are trying to solve a heating issue, but I don´t really want to read all 184 pages to get the solution. I didn´t disassembly the device yet, don´ t know what is in, etc. Do you have some recommendation, where to order "thicker thermopad" or which dimensions it should have, etc? I can see also somenthing about replace a stock fan by "V2 Sunon 7500 rpm", which should be more powerful..

Is there some conclusion how to improve this potential problem by your side, where to buy it or how to design it, as I can see you are quite nice in the topic for some time, please? My CPU has normal operational temperature of 85°C as I can see in he device and this is too high to any semi-conductor element, which could degradate fast in this way.
[Android Head-Units] winggndm1:
I had high temps also after updating before with out clearing settings when doing the upgrade. Try to reflash but with reset settings enabled. After that i went from 80-82c idle to 50-51 idle.

Also has anyone had issues with wireless carplayon the latest version (0819 i think)? The microphone will not work on wireless carplay but does work using wireless android auto. Tried to factory reset and setting everything back up but still same issue. Will try to downgrade to see if it's the new version. Iphone is an iphone 11 on ios 16.6.

update: Just downgraded to 0712 and the microphone is working on wireless carplay again.
[Android Head-Units] lone_slayer:
Have you tried just doing a reboot? I had no usb working after my last update and a simple reboot fixed it. Slide notification bar down and press reboot. Worth a try
[Android Head-Units] marioti:
I can't give you a link where to buy anything, because don't know where are you come from, etc. Just look on your local market.

1. First of all, try like the winggndm1 said. It is possible that some of your settinsg or app causing the heat problem. Try to downgrade (or upgrade) soft to known 0712 (0714), but with whipping all yours data (unfortunatelly)

Even on stock HU, i never had 80-85 degree. Normal was 65-75.

2. Fan was modified by user blueone. he as the first proposed to chage it by Sunon 35x35 fan. And it's not because better cooling, but the stock fan is jus rubbish and noisy. If you want to modify this, just look for MF35101V3-1000U-A99 fan. It is for 12V and 5000rpm, or if you want louder but more efficient MF35101V2-1000U-A99 (for 7500 RPM)

And in my case, it is better that fan blow inside, not outside.

3. Thermopad, just look for some efficient like 6 do 10 W/mK. The thickness is depend what big gap you have. For me it was 1,6mm, but better be if you check it. And it is a small piece like 14x15mm. When you open it you'll see the metal plate surrounding the cpu, and just fit the thermopad in hole.

Disassembly is quite easy. Just unscrew 4 screw outside housing. Then you have to unmount one plug and 3 ribbon tapes. Then unscrew 5 more screw in mainboard, and thats it (if you have optical and coaxial plug, need to unmount one more plug when you go up with mainboard)

4. It is depend wat car you have. Small, closed space from the back of radio never be good if you want there low temps. Just think about it. maybe just like in my case (and other also) tou can make some ventilation from upper middle air duct. I have a ventilated glovebox, so i just plugged the flex pipe to this duct, and give the air direct in fan area. Now i never see temps higher as 50-55, standard (radio +navigation apps on) it is ca 38
[Android Head-Units] Aaantonn:
You don't want to read, but someone should strain and help you) You're a fire guy!)) The distance between the processor and the case is more than 1 mm, some people have a thermal pad in the radio right away, I didn't have it. You can see in the photo, I put the plasticine and closed it, opened it and saw what a gap. I glued a 1mm copper plate to the hot-melt adhesive, and on top of the Honeywell PTM7950 termopad. Perhaps thermal paste will suffice instead of Honeywell PTM7950. The usual thermal pad with a thickness of 1.5 mm. can't cope, I checked on the laptop! Now the fan rarely turns on, the temperature is up to 65 degrees.
[Android Head-Units] marioti:
I need to add, in my case copper plate + thermal paste caused higher temp compared to thermopad. I don't know why, but i tested 2 times (cooper plate > thermopad), and thermopad was better. My tests are also described in this thread.

Maybe if i used PTM7950, it had more sense. Bud i didn't have it and the price is not low
[Android Head-Units] chadoe:
This also solved the constant 80+ temperature I had last month. After reflashing with reset settings the temperature has been mostly below 50.
[Android Head-Units] lontrish:
Still cant solve the issue with the screen being too dim during the day. I noticed that it would sometimes be bright enough but suddenly dim itself (even though the slider is still at 100%) making it extremely hard to see.

I updated to the August version and been getting so many issues. Zlink also gone.

I tried downgrading but it keeps giving me an error and failing so I'm not sure how to address this.
[Android Head-Units] lone_slayer:
I updated to August update and am using zlink. The first time I used it with no internet connection it didn't work but it did work when I had a wifi connection. It needed to register it.
[Android Head-Units] lontrish:
The main issue for me is that Zlink is entirely gone on my device (even when I changed the factory settings to Carletter then back to Zlink). It doesn't even let me downgrade to the previous firmware either. It seems like it's just not even installed.

Edit.

Somehow was able to downgrade and get Zlink back.

I still don't understand why the backlight just gets lower even when it's on 100% though.
[Android Head-Units] Astralech:
With copper you had very good conductivity and the processor received a higher temperature with the case from the power amplifier. You have installed a thermal pad that does not receive temperature from the case to the processor.

I had the same, I gave the radiator to the amplifier and now without a fan I have a temperature up to max. 55*C.
