Decided to try my luck)

I downloaded v.2.93_02 from the Chinese link and installed it, this time it installed perfectly, without incident!

I checked all the functions - everything is OK.

After flashing, CANBUS was updated.

46th item has been added to the settings menu: Zlink Hicar Enable
[Android Head-Units] Barykelo:
I had an FYT from Mekede and got rid of it quickly! For one thing, they are overpriced and the software is very poor. The software is at the level of car radios five to ten years ago!
[Android Head-Units] Barykelo:
Yes, there is an update for both the CarAPP and the canbus (Raise).
[Android Head-Units] Yevhen7788:
I installed update 2.93 using the link sent by the seller. everything installed well too. But again, when driving, the volume began to fluctuate, when picking up speed it becomes quieter, as soon as you stop it returns. and the music started playing again, the device froze and rebooted itself. Now I set it to 2.84.
[Android Head-Units] Yevhen7788:
This fall I installed my brother’s Hyundai Mekeda M6Pro, everything works smoothly, no glitches or freezes. there are no reboots the phone connects very quickly
[Android Head-Units] MauriBixio:
The canbus update (and CarApp) was already available via OTA for at least 3 weeks ago, even WITHOUT updating the firmware (I use October firmware, with changelog) so this is not new by the January firmware.
[Android Head-Units] Zebnastien:
In sound settings, disable "Increase volume with speed" setting.
[Android Head-Units] Yevhen7788:
everything is off as far as sound is concerned
[Android Head-Units] Yevhen7788:
despite the fact that I only need Car Play and a reverse camera from the device
[Android Head-Units] Kinchefff:
Did you notice that my СANBUS firmware was updated from January 10, 2024 to January 11, 2024?
[Android Head-Units] Yevhen7788:
Same thing at 2.84. The volume fluctuates between quieter and louder, even when you stand still.
[Android Head-Units] MauriBixio:
And you almost certainly didn't notice any changes in the previous REAL functions via canbus between your car and the radio, right?

These canbus firmware updates (via OTA or radio firmware) are essentially for CarApp canbus, but they CAN NEVER update the firmware internal code of the canbus decoder chip you use, so even if you see more functions available through CarApp, in reality the situation does not change anything compared to real things that previously worked via canbus between car and radio, so everything remains (almost always) as it was before...

Hi everyone. I've been using mcu-qf03-14-8-2023-bu32107-tda7708 on an S8 8/128 for the past week, and I have a problem with the bluetooth connection. When the unit comes up from a completely shut off state, bluetooth is disabled by default, and I have to enable it manually to connect. If I perform a restart, bluetooth comes up instantly. Also, It's just me or the latest firmware version brough the older carplay interface back? In a previous version, I had the one with the icons on the bottom, and smaller icons too. Thanks

[Android Head-Units] Barykelo:
You gave little information. Was everything fine before the update?
[Android Head-Units] chadoe:
My radio did this last week with the flashing button lights when it was very cold and my car turned on all the heating. I think the battery just couldn't provide enough voltage for the radio. It was the only time I've seen it.
[Android Head-Units] Mr.TT_NZ:
@Barykelo

Thanks so much for uploading those two latest files! And thanks for using Webshare as that works very well for me which Google Drive does not.

How are you sourcing those files? I note that in the general thread a poster expressed concern that Jitu has disappeared from Alibaba (post #5055) so does that mean there will be no more of these units available to purchase in the future and no further firmware / MCU fixes?

You have listed new firmware 12.1.2024, I'm downloading it while I type this. I see no mention of it yet, is there any changelog for this one since there was not for the November FW? Do you have any idea of what may have been changed if there is no official info?

I've just ordered another S2, when it arrives I'll load those new files and see if it fixes two issues I have found in the unit I just installed for a friend.
[Android Head-Units] Barykelo:
Don't worry, nobody's gone anywhere. You should buy version S5 and above at least. It has a higher quality radio module and a fully functional DSP. The DSP BD37534 has only a fraction of the settings functional.
[Android Head-Units] elpardua:
Take this as an unnofficial changelog: I dunno if was intended, but I had some audio choppiness in wireless carplay where driving on the same spot of highway near home (some speed traps, antennas and stuff there), this version seems to handle better the interference, no interruptions at all.
[Android Head-Units] Mr.TT_NZ:
If I was buying for me I might go for one of the higher models but the S2 is perfect for the people I have needed to get one for. None of us need the 4G / LTE function for example. Also the cost rises rapidly as you go up the models so the cost vs functionality is better with the S2 for people who are not so well-off but want to replace the Japan only units in the Japanese import cars we get here. This one I just bought and won't arrive for a couple of weeks is to replace a Sanyo NVA-HD7708 unit in a Nissan 8 seater people-mover bought by a family with many children.

2) use the widget to link the voice "system"

3) in the system you will find the stock android voice to reset the device

Hello to everybody. The question is, does anyone have experience with the winter season. My radio only starts after the car warms up. Then right away.
[Android Head-Units] 19vik:
I have some similar issue, almost daily. When I start the cold car, fm radio starts as it was in last state, when I start navigation app HU it freeze (touch screen, physical buttons do nothing) for 4-5 minutes, than go on and works normaly.
[Android Head-Units] MauriBixio:
Last night car outside, with -3° C, radio start (S8) without problems...
[Android Head-Units] MauriBixio:
This seems more like a problem with the Touch screen device, in the cold, and not with the radio...
[Android Head-Units] 19vik:
Maybe you have right, but I have S5, 8 inch display with physical buttons, vol+/-/mute and tune, those not work too. Not at every cold start, but it happened at -3° C and at +6° C. Also, from a while, outside temp in status bar not update until I go to can settings> car info.
[Android Head-Units] Barykelo:
I got into this setup too. The problem is that the factory reset did not offer to write the code, but there was only an error message. I don't remember which one anymore.
[Android Head-Units] brzanek:
After updating the latest version, I have a problem with sound, nothing plays.
[Android Head-Units] MauriBixio:
Since I understand that many users have problems updating with the latest firmware updates, why continue to do so?

Are masochists?

I update ONLY if I have a firmware with changelog, and currently the ok one is October firmware.

There's no point in being a beta tester with firmware without a changelog...

I've already written, don't try every new firmware release if there are no safe fixes.
[Android Head-Units] chadoe:
Did you install a new mcu? If you install the wrong version mcu for your radio you won't have any sound until you install one specific to your radio.

CHANGELOG????? man wake up... this is chinese product....even they dont know what they did in FW..forget about changelogs....people here risk their car, because (many bad words about some asian country) are lazy, incompetent to do things right. Everything they do is ALWAYS bad tranlation because spending 20$ on translator human who knows english is too much. Always fail at most simple things. Love how they write it's android 13 while in fact it android 10 and seller tells me, oh those 3rd party apps show nonsense, ou technicians know better it's android 13 :DDDD while you cna see with file explorer system app directory have android 10 files! like easter egg applcation and so on :D They are INCOMPETENT and eveyrthing they create is stolen from western manufacturer and created with eyes closed and in a hurry. So you, i ..we all are not even beta, alpha testers.

I have newest FW 20240112, tried to isntal older version and unit fails to do so, forget error,but something about footer.
[Android Head-Units] Mr.TT_NZ:
@afigienas

My comment was that none of my friends so far have needed that function, I was answering @Barykelo's comment about why specifically I did not buy a higher spec unit. Maybe your translation changed the meaning of what I wrote, it was not commenting on what other forum members need which will obviously be different from my / my friends' needs. The units fitted to the Japanese vehicles which come here are very specific to the Japan market, the radio frequency coverage is wrong, they cannot run any navigation other than their factory hard coded app and no maps other than Japan can be used nor can any actual apps be used so we're changing the unit for those reasons but everyone so far has their own cellphone so do not need another in the head unit (this would need a SIM from a network operator which will incur ongoing unnecessary cost).

Sorry you got the wrong message, but go back and read what I wrote again i.e. the words before what you highlighted.

BTW there HAVE been changelogs in the past!
[Android Head-Units] ciscovti:
Very strange, this is the stock androind interface and in my case ask for a password. I have inserted it and unit has restarted erasing the settings. Then it started again with the last firmware with all parts working. The only things the has a strange behavior for me is the music player. It has a low volume (like 50% of the master volume). Radio, Spotify, blueetooth volume is ok.
[Android Head-Units] MauriBixio:
Man...I've been awake a long time!

I already know everything you write, better than you, so don't lecture me. ;)

We just need to inform NEW users that in addition to having low-cost Chinese products, with developers who know nothing or almost nothing, they also DO NOT make the mistake of updating the units with firmware without (at least) some "hypothetical" firmware development changelog "minimally stable", and usually those with accompanying changelogs have been so until now (more or less...)

but you are right that we are ALL alpha-beta testers, many things are questionable about these units, and developed VERY roughly, with LITTLE effort.

Android version:

it is known that v.10, 12 or 13 is fake, we have written hundreds of times.
[Android Head-Units] inscriber:
Why there is no custom ROMs already? Every unit in the psat that I have from px3 to px6 have custom roms. What is the problem here? I'm not a Dev so please excuse me if the question is stupid.
[Android Head-Units] Vampire_Dracula:
Actually I bought mine for music. My S8 has clearly better music quality than my old crappy 2019 OEM headunit from Honda, delivered with a built-in filter meant to protect their crappy OEM speakers.

This headunit has great sound, I even dare to say that it sounds better than my large floor standing Infinity speakers coupled with a Yamaha receiver I use in my living room. Probably also because of the confined space and my aftermarket underseat subwoofer (with independent tuning available on this new HU), but it doesn't matter, the sound is great!

Hello all, it seems that there are some QF001 owners out there but not much informations. So i will try to collect everything and put it at one place. The original manufactor is shenzhen jitu technology co. ltd. These units are sold from...

xdaforums.com

be careful if you unbrick Hizpo S8 G4 8 Gb/128 Gb (BU32107 / TDA7708) with the pac file (QF001_jitu_20230109_user_carletter_v3.08.pac) and UpgradeDownload tool.

Although your device get alived, and it is a very good news, you might loose 2 Gb of RAM from 8 Gb. Only 6 Gb are recognized in the About section (Store Information).

Probably because that stock rom pac file was created from a S8 6 Gb unit and it is very outdated (1 year ago).

I do not know where to find the newset pac file for this device. Maybe is something that Jitu saves internaly.
[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] Serruxo:
Thanks for confirming the issue and thanks to you for sharing the steps to unbrick the device few days ago.

Please read the recent related post https://xdaforums.com/t/general-dis...d-read-first-post-first.4525675/post-89287558

It seems UNISOC 7868S processor only supports 6 Gb of RAM instead 8 Gb...

Waiting for news about a valid and more recent pac file that fixes this, and try to get 8 Gb although it is simulated (maybe 6 Gb real + 2 Gb of swap).

You are all lucky to revive the unit from bricked state, i couldn't do it I don't known what but I think I broke by unpinning something usb device not recognised by windows. So I ended up sending the unit back and hopefully to get a new one.
[Android Head-Units] Serruxo:
Yes the most important thing was to rollback the bricked state and getting the device to life.

Procedure was very well explained, but I recommend to you, read the internal .doc file and watching the videos that come inside the .rar file.

Regarding the USB cable, you do not need to use a USB to TTL converter, if were the case.

Only need:

1 - USB A male - USB A male cable. One side to the PC and the other side to the female USB cable that comes with radio.

2 - The original USB female cable that comes with the radio, specially the 6-pin one.

2 - That 6-pin white female connector can be used if you first remove the metal pins from the white connector to recolocate them in the right possition for the male 8-pin connector from radio as shared picture shows (you can follow the cable colors put in right order). That 6-pin white connector from the USB cable can be connected with care in that 8-pin connector, pressing it carefully avoiding to blend the rest of pins. For me worked.

3 - Remember connecting pin 1 from 10-pin male connector of the radio to Ground GND. You can use the metal or exterior part of the GPS or 4G or ANT connectors as is shown in pictures on that .doc file inside the .rar file shared to do the procedure.

4 - After unbricking, remember putting in the original position all the relocated pins of the 6-pin female white connector of your USB cable to avoid electrical failures or maybe damage the radio if you use that USB cable further.

Hope this helps better and you can unbrick your device as I could did.
[Android Head-Units] PrinceLc:
Thank you but unfortunately I didn't get to manage it tried it one week nothing so I ended up to send back the unit for warranty and get a new one when Ossuret get the old back. Fingers crossed that I get really a new one. But for all other here wher the warranty is endet it's a good point. I think my fault was to unpin not gentle enough so I damaged maybe some connection of the cable, the PC couldn't see the unit all the time.
[Android Head-Units] MauriBixio:
In the next few days I'll download the package with .pac (now I'm out and I can't...) better to have it available, just in case!

But, here you write:

"

2 - That 6-pin white female connector can be used if you first remove the metal pins from the white connector to recolocate them in the right possibility for the male 8-pin connector from radio as shared picture shows (you can follow the cable colors put in right order)

"

Is this shared picture of cable included in the download .pac package?
[Android Head-Units] Serruxo:
Yes, inside the package, exactly the file called "4Gxxxxxx.rar" (name in Chinese), you have a .doc file with useful pictures of the cables, colors, pins of rear side or the radio and a .mp4 file that shows the manual procedure to load the .pac file in flash tool and the way to transfer the file.
[Android Head-Units] Monolithus:
If I understand correctly, I shouldn't be upgrading QF03 to QF05 if I have S8? (different DSP's, radio IC's)
[Android Head-Units] afigienas:
Just to make sure, at least in my car Jeep Renegade, in Can app i have to go to AMP and there there is volume, i had low volume from all versions, i have to in AMP settings brigh volume up. My AMP controlled by CAN BUS. So if i set volume in can app then it sounds as it should. Looks like i can set amplification with can app, and then as regular via steering wheel use volume. Maybe in your case the same?

PS how do you go back to older FW? i tried and got some footer error. and failed update. (my device is S5)

It would be awesome to get normal android in there. or at least normal launcher.
