Yes, I had ask Hizpo for support.

1. reaction: we will send you a new ZLink5.apk

the installation was refused.

2. you sent a complete firmware update (update.zip), installed it, the ZLink5 software is still the same with the same version number and does not work.

3. I am waiting for further answers...

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...

[Android Head-Units] Emil-Erpel:
Is the internal name: com.syt.zlink5 ?

so the deletion command is then: pm uninstall -user 0 com.syt.zlink5 ?
[Android Head-Units] bloot:
To find out the package name run first

pm list packages -f

And then search for something containing zlink I guess

Hi, I need help.

Today I updated firmware 20240709_v3.12. After update head unit boot normaly but I can not go to setting (setting not working anymore). How can I downgrade firmware when I can not go to settings?

[Android Head-Units] Seba_12:
Download older software and burn to a USB drive. Name the directory on the disk "update_auto.zip" and insert it into the USB port on your device. The installation should start automatically.

[Android Head-Units] hojnikb:
Can someone explain MCU upgrades to me? i've seen QF01, QF03, QF05 mentioned here. Does this relate to HW version of the MCU or just software? My unit came with QF01, but the latest update starts with QF05 and won't even update due to mismatched version.
[Android Head-Units] wit.cz:
My came with QF05, however, I have seen QF03 with the same release date. I doubt that this is only sw change and it really might be hw (some radio or dsp chip generation of the same type) related.

[Android Head-Units] chkoeber:
Links in S Series Upgrade tutorial seems to be broken

Please use the system software and MCU collection links.

Important:

Check the DSP IC and Radio IC in your player.

The DSP IC should be BU32107 or BD37534,The Radio IC should be TDA7708 or TSC4745.

This is very important since different IC need to upgrade different MCU. The wrong MCU document can lead to no sound issue.

Latest MCU versions:

Latest MCU version for DSP BU32107 & Radio TDA7708 = mcu-qf05-22-5-2024

Latest MCU version for DSP BD7534 & Radio TSC4745 = mcu-qf05-6-1-2024

Latest MCU version for DSP BU32107 & Radio TSC4745 = mcu-qf05-6-1-2024

Copy the <mcu>.bin to your USB flash drive root path or direcctly in internal flash root path, do not rename them. Do then the System update as shown in below pictures.

The device will restart during the MCU upgrade. This step will take about 1 minute.

In case you will get by MCU upgrate the MCU upgrade file does not fit current platform! error:

Enter 114477 in factory settings and then you will see a short simply chinese text at the botton which means “Open Developer Options” which will disable signature verification when trying to update the MCU.

Try the update MCU procedure again which will be success. 👍

Latest system software versions:

Latest system software for horizontal screen 1024x600, 1024x720 or 1024x768:

QF001.20240722.165508 (3.13)

Latest system software for vertical screen 600x1024, 720x1024 or 768x1024:

QF001.20240531_v1.15

Copy the <update>.zip and to your USB flash drive root path or direcctly in internal flash root path, do not rename them. Do then the System update as shown in below pictures. The device will restart server times during the system upgrade. This step will take about 6 minutes.

Disable "Check the upgrade file for corruption" (default)

Enable "clear user data" (default) / Important for a correct working system! All data get lost and Radio is factory reset!

Update procedure screen

For a guideline you can use the S Series Upgrade tutorial anyways.

Good luck and have fun 🤞🏻
[Android Head-Units] Saiphable:
It is functional downloading from their site right now... (y)

:D

After update I have got bootloop on Powered by android ... now what:unsure: DSP BD7534 & Radio TSC4745
[Android Head-Units] Barykelo:
This is not K706.
[Android Head-Units] chkoeber:
Do you have a USI7862A or USI7862S central processor?

Check in system information menu at the bottom:

I think not and I'm wondering because you system version is QF005 and MCU QF30 which does not fit the Firmware QF001 (ROCO K706) for Head Units with UIS 7862a/7862s.

I think you can just try to Hard Reset Car Radio Android 10, 2 din / Update with files

What does the resistor delete do?
[Android Head-Units] Elrathias:
It gets rid of a high pitch omnipresent whine (about 8.7kHz) caused by the 4g modem feeding back into the common ground when you are not using that functionality.

Its practically mandatory on all first gen pcb's
[Android Head-Units] chkoeber:
I also have such an annoying, quiet running noise when an audio output is played, but it contains silence.

But you can only hear it when the car is off and it is quiet in the surrounding area. If no audio output is active, the high frequency signal also disappears.

Do you know what causes this?
[Android Head-Units] hojnikb:
Cool, was not aware of that! Is there a tuturial which resister has to be removed? Any other known HW mods for this rev1 board?
[Android Head-Units] Elrathias:
Most likely the LTE modem circuit. Download a frequency analyzer app and see where the peaks are. Going to be different for all amplifier-speaker combinations, but it was VERY noticeable when i wired it wrong and put speaker level inputs into my amplifier (ear piercingly loud to be honest, and very annoting even at -15dB on the preamp)

The previous FW on AutoFather was the 0328 so thats why I think it is the 0414 now or maybe something newer.
[Android Head-Units] balkanera:
But this is 08.5.2023.. newer version
[Android Head-Units] jagd71:
Already installed fw 230508, from auto father. It says version 4.19_02 once installed. So far, after a couple hours using it, it seems my problem with 4G not having usable connection after booting is solved!. I'll check again tomorrow and following days but now I don't have to disable/re-enable mobile connection to have it working, yuhuuu.

Aside from that it seems a bit quicker to boot and as previous version (4.11) you can uninstall TXZ service and some other included apps that could not be uninstalled before.

I attach a photo of the version

[Android Head-Units] Gyovany96:
Quick question: Don't need to update MCU too if I already have last version, right? Just update firmware
[Android Head-Units] jagd71:
Bass filter was already working for me (with previous version 4.11 and also 3.92). It's quite noticeable for me. But bassboost does not make any change to the sound and I don't use.

That's right, you don't need to update MCU. Latest MCU version is still 232007
[Android Head-Units] ImBenny:
Bass settings only work on RCA outputs for me.
[Android Head-Units] Gyovany96:
Thanks! Also can we Dirty Flash it or Clean Install is mandatory? Don't want to setup whole HU again or maybe I can use Export/Import option from Factory settings? Tho I still don't want to install all apps again and log into accounts too.
[Android Head-Units] npolite:
Hi All,

I have purchased this unit and found a few issues with it S5 6G+64GB.

1) Bass is very poor. Is there a way to set it any better? I tried in the equalizer but it still doesn't sound like stock on my 2012 Camry

2) The steering wheel controls don't seem to work. I've tried every possible canbus setting but it still doesn't work. I'm in contact with the seller to see if they can help me out.

3) When I have the volume at 5 it sounds very loud, is there any setting to make the increments smaller so they don't increase the volume as much going from one number to the next?

I have not done any of the FW updates yet and mine seems to be set from Feb 2023. Will do this at some point today.

Thanks,

Nick
[Android Head-Units] MauriBixio:
S8 8GB\128GB

I have firmware 0414 and MCU 0207.

I know is it possible uninstall some default apps with this version.

In particular, is it possible to uninstall "TPMS" default app?

I use a TPMS hardware interface that is not compatible with this one (and you need a different app) so it's useless for me to have the default one,which "disturbs" when I use the suitable TPMS app.

But I don't understand how can I uninstall TPMS defaultapp...steps to do this?

Thank you
[Android Head-Units] ImBenny:
You can just update.

You don't have to do a fresh install except if you experience bugs or other faults.
[Android Head-Units] ImBenny:
Try to delete like any other app and see if you can or not!
[Android Head-Units] itiswitis:
General thread is probably better suited for these questions, to keep this thread decluttered, but responding at the risk of getting flamed since I had similar issues on my 2014 Camry.

1. Lots of tuning with the DSP. Flipping through the preset EQs should produce changes in your sound quality. Start with one you most prefer and tune it to your liking. You could also try to the bassboost settings, there has been "mixed" results from folks. Sub-boost is for subwoofers connected to the RCA sub output.

2. Connect to wifi/internet. Then reselect your car in the canbus setting. Mine was Simple/Toyota/Camry/12-13. Internet has to be connected first.

3. No. It's still very loud at the low volume. I was able to work around this by tuning the EQ to very slow settings across all frequencies.

My S6 also came stock with Feb 2023, it was very stable. I upgraded to 0414 to get speed volume control, which Hizpo said was not available. Upgrading to 0414 wiped out my DSP settings.

Anyone know if there is a way to save the DSP settings?
[Android Head-Units] marioti:
As for now, there is no way to save any user profile. I ask about it my vendor Ossurer, a couple days ago. I wanted to report this need to producer (Jitu). But seems to Ossuret don't see any problem, and they wont help.
[Android Head-Units] MauriBixio:
I was wondering if anyone had succeeded because for TPMS app it doesn't seem possible to uninstall.
[Android Head-Units] itiswitis:

Software tool not easy to use with PC and with unit installed in the car, but still very useful to know that it exists...thanks!

Another possibility instead of uninstall could be to DISABLE forever ... but I have to investigate if it is possible to do it and how with TPMS default app ...Nobody?
[Android Head-Units] ImBenny:
I've installed the new FW from Autofather on my S4, and now I've got stucked on this screen:

"GPS Speed keeps stopping"

Can't close it. Can't access UI.

Edit:

I've successfully downgraded back to 0328

It works but all my icon layouts gone. 🤯

Edit2:

After downgrade, I noticed that there is a missing icon.

I rembember that about a week ago a new icon appeared called GPS "something" from nowhere.

I tried upgrade again because I think the downgrade cleared that what triggered the error and BOOOM IT WORKED!

Now I have to set back my icon layout but the latest FW installed.

It is so hard to get an icon move to the next page, isn't it?

Edit3:

After changing to my previous launcher, my icon layout magically got back lol

Every launcher has its own icon layout?

There are also here that strange app called: "GPS Test"

Do you guys also have this?

I think it is recommended to switch back to default launcher before update. (It is the second from the menu to me)

I also switched back language to English during the process to be sure.

Notices:

The settings app crashes when you hit "Storage manager". You can turn it on but can't open it. What it does btw?

Spotify app still has random crash. Not often but it still has.
[Android Head-Units] balkanera:
so I Test the new firmware looks good.

What I noticed is that the dsp settings don't change anything except the equalizer. but if the radio is restarted, the settings that have been changed can also be heard in the sound. is annoying when fine-tuning but better than nothing. it's most noticeable with surround sound, of course
[Android Head-Units] snaker12:
The function that when you make a call you cant hear the beep sound from speakers is very annoying. Is it still there at this firmware like it was at the last firmware release?
[Android Head-Units] xdsbx:

[Android Head-Units] Elrathias:
These questions should be asked here: https://xdaforums.com/t/general-dis...s-not-fyt-based-read-first-post-first.4525675

However, you need to demount the stereo from car, and take a photo of the canbus box; this info is needed when selecting the right canbox in the CAR APP settings dialouge, to make steering wheel buttons work properly.
[Android Head-Units] Elrathias:

[Android Head-Units] itiswitis:
Yeah, you would need a laptop.

[Android Head-Units] Costi979:
I have been installed last version 1 week ago, all I saw new was posibility to choose ring tone. And to uninstall unnecessary app.

Looks like they are working indeed on these updates, but I still have issues with the sound. Loud and distorted, problems I didn't had with stock firmware. That is the reason I searching for.
[Android Head-Units] MauriBixio:
The choice of ringtone and the possibility of uninstalling stock apps (actually THEY ARE very few, many stock apps cannot be uninstalled, e.g. TPMS, which I don't want to have, but...) is already possible with firmware 0414.
[Android Head-Units] snaker12:
So is it still missing or you can here the beep beep sound when you make a call?
