Hello

I Have Chines Head unit ZXDZ 01

I try to update with wireless update

I found their is new update available

ZXDZ_2020.03.05.18

I downloaded Succeffuly in Device but when i try to update

I got error

Can any Body Know How to fix this issue

Thanks
[Android Head-Units] aysoy:
plz my friend did you fix the fader sound control yet , help me if so plz
[Android Head-Units] ExtremeMOD:
Guys, the reason your unit doesn't have EQ or fader is that it's missing an audio chip. Older units all had it, like YT9216, YT9217, YT9218, and even (older) YT9213AJ. If you buy Android 8.x or 9.x then the audio chip will be present.

See the pictures below explaining the issue.

The audio chip is TDA7729 (TDA7719 , CSC37033 , SCS37534).

Now there is a fix but it requires advanced soldering skills and a proper setup.

Sorry to be the bearer of bad news.
[Android Head-Units] ofarook:
I've got same unit with updated firmware. I bought power player pro to get eq control, works perfectly in my Benz. Don't need fader so never bothered.
[Android Head-Units] GnatGoSplat:
The soldering actually doesn't look too bad, I've done a lot worse.

Is there an actual documented fix thought? Looks like it might need more than just that chip. I see some capacitors, transistors, etc. missing as well, so it looks like it needs that chip and everything connected to it.
[Android Head-Units] aysoy:
guys what is the best setting in audio pannel et fix a little bit the fader issue
[Android Head-Units] ExtremeMOD:

[Android Head-Units] GnatGoSplat:
Google Translate doesn't really do a great job with that, but I guess it's probably not worth the effort considering a better one isn't that much more expensive.
[Android Head-Units] ExtremeMOD:
I speak Russian. I might translate that post and share it on XDA, seeing as all of the newer units are missing the audio chip.
[Android Head-Units] ExtremeMOD:
That might be the case but without that audio chip, the sound quality is beyond horrific. It was already bad in the older units that ran TDA7388 amplifier and already had the chip.

Now you're getting YD7388 amp (that's a crappier version of already crappy TDA7388) and no audio chip.

Not even PowerAmp can help you, I'm afraid. Viper4Android can't do much either.

Luckily, for just a few dollars, you can upgrade to TDA7729 audio processing chip, then add TDA7850 amp powered by a 10,000 uf capacitor and install proper cooling system to support the insane power that TDA7850 produces. Then root your unit and install Viper4Android. Then with proper configuration, the sound quality from your Android will be on par with hi-end Android units, that for example Mercedes sells for £5,000 or more.

Check the video in my signature for more tips.
[Android Head-Units] tankata:
Hi mate, I have head unith like that

can i add to them audio and radio chip? Someone can give me more guedes to do that ?
[Android Head-Units] ExtremeMOD:
You can but unfortunately this isn't a (what we would call) a standard model. I thought you had something like this:
[Android Head-Units] tankata:
Yeah, I know that it is`t standard model. But can`t i add at least one of them?

On the board have empty slot i thought for radio chip, but i am not sure what exactly and what more element need to soldering and wath need change in software (firmware)?

On picture in internet i saw same boards with chip "Techpoint TP2804" in that slot.
[Android Head-Units] mr.willem:
@iceblue1980 I am quite impressed by your work.

Thank you for sharing.

Besides cooling and antennas. When it comes to the ICs.

Do you only change the audio ICs TDA7719 / TDA7850 on those units?

Or do you also change other ICs? Like radio receiver or so?

Is the unit "strong" enough to handle Navigation and maybe even OBDII - Torque with your firmware?

Is it possible to handle two bluetooth connections at the same time?

Thanks a lot

mr.willem
[Android Head-Units] ExtremeMOD:
Appreciate that. Thanks. But to be clear - none of the mods that I do, are my creations. I do a lot of research and then follow the guides that I find. It helps to be a Russian speaker as well, as most of the stuff I learned are from 4PDA forums.

The only thing I can take credit for is the adaptation of the mods, when it comes to the way I make the units look on the outside and the way I configure them.

I've been doing this for about 18 months now as a hobby project to support some charities out there.

To your question - here's the list of what I normally do:

1. Radio: change internal electronics to considerably improve the sound and reception quality of FM

2. Completely rebuild the sound system: installing TDA7850 running at 18v max capacity (DC-DC step-up converter) with 10,000 uf capacitor, supported by a temperature-controlled external fan with its own DC-DC step-down converter (you don't want to use the internal power at all, for anything). In the video in my signature you will also see an additional external heatsink and I also install bronze heatsinks inside the unit to control the heat of the amp.

3. Heatsink on CPU

4. External Wifi antenna

5. Custom internal mic

6. TDA7729 audio chip (if not present, like on YT9213xx models)

7. Custom Android OS with all the bells and whistles.

8. Viper4Android to further improve the sound.

Yes with the modded operating system, this unit can run TPMS, navigation, HD video, and everything else.

Hope this helps

Anyone manage to update, I still get the dead robot
[Android Head-Units] h3llrai53r:
how do you do that boss
[Android Head-Units] mr.willem:
@iceblue1980 Thank you very much for your reply. This is very helpful.

I just ordered one unit and will see whats inside.

Fortunately, I am somewhat experienced with SMD soldering and MCU programming.

What Step UP IC do you use to generate the 18 Volt?

Is it sodered directly on the PCB or do you use an external smps for it?

Do you know whether there are some schematics of the circuit anywhere?

As far as I understand most of the PCBs of those Headunits follow one reference design and are

populated with somewhat more or less quality parts.

I tried to find it but had no luck up to now.
[Android Head-Units] ExtremeMOD:
That is great. Certainly your skills will help you to achieve this and more. As for the schematics - you're absolutely right, they are hard if not impossible to find. I use this step-up module and this step down for the fan control. I use external enclosure for the step-up module, while attaching the step-down one to the motherboard as it fits perfectly below the main socket (see pic)

Perhaps we can collaborate as I still got much to learn, both in electronics and MCU programming. Feel free to PM me and I can share all the resources that are currently available to me.

Also, because I mod and sell these units (for charity), I need to think about how they look on outside as well. There are probably easier ways to mod them if you just do it for yourself.
[Android Head-Units] ofarook:
to be honest i dont know much about ics & stuff, right now all i know is that im amazed by your video, went to my car, removed the hu and opened it. now i dont know where to look for those number. which file should i flash, will leave the ics for later.
[Android Head-Units] ExtremeMOD:
Thanks! Glad you appreciated it.

You can see in the video that the motherboard is completely different so unfortunately I don't know what to advise you. Sorry
[Android Head-Units] ofarook:
I'll take the risk.

ok so the situation is that it did not react to connection to pc, nothing on the pc side as well. so i bought 220 to 12v converrter to power it. even then no difference.. pc wont find hu now hu find pc
[Android Head-Units] ExtremeMOD:
This sounds like a drivers issue. Check out this post where you will find a link to driver installation instructions.
[Android Head-Units] ofarook:
Was trying to connect when 6 pin usb, my mistake . Pc recognized with 4 pin, didn't notice that in your instructions. Now can't get bootloader, unable to find points for hardwire.
[Android Head-Units] GnatGoSplat:
Unfortunately, looks like mine has no place for the audio chip (iMars branded type).

One interesting thing is my LCD was plugged into the smaller of the 2 large connectors on the right in my pic. The bigger one is unused. It looks like other people, the LCD uses the bigger connector. I guess there are 2 types of LCDs commonly used? Are some IPS and others are worse? Mine doesn't have very good viewing angles. Also, what is the connector in the middle of the PCB above the big connector for? Kind of looks like a CFL connector. Mine had nothing plugged into it. I see in other peoples' pics, some have a thicker red & black wire. Others have a white & black wire. Are some of these CFL and others are LED?

I need a fader because my rear speakers are 10x louder than the front without fading, so I guess I'll sell mine. If I get an Android 8/9 version, would it have the sound chip? Do all Android 8/9 models have the sound chip, or is it random?
[Android Head-Units] ExtremeMOD:
Yes it is probably best to get a new unit. Below are the models that have Audio Chip:

YT9216B, YT9217B, YT9128C, YT9216BJ

YT9213AJ and YT9213A normally don't come with the chip.

You can PM me if you want recommendations on what to buy and where (no affiliations on my part) or if you want something really hi-end, then I might be able to help you as part of a charity project I'm currently running. Cheers

I bought an Android Auto Head unit (ca7023), it has Wince system, but no nav, no way to enter windows system too. But sound is low, in this internals it have an yd7388 and 2200uf caps, I will change to tda7854, in datasheet this is pin compatible too, but double the watts. What caps mod do? change 2200uf to 10000uf? It raise temps of amp too? I have standard speakers, My older stereo have 60wx4 mosfet amp, maybe an pa2030a I don't know but are much better, I only change because android auto is a must to travel and city.

Hello Guys.

I'm new to this forum but I have been dealing with an annoying issue with this equipment ZXDZ-01.

I bought one ZXDZ-01 Android head unit 2GB, 16GB, Android 10 and install it in my old BMW E46.

The issue is everytime that I connect my phone via Bluetooth to the unit and share music the music is constantly being cut. Cuts may even during some minutes then return the sound. While it cut music still continue to proceed. The same is happening with hotspot. I installed an app with Portuguese Radios and share my phone's Internet, but it runs with cuts many times it's such annoying.

I already turned off phone's WiFi, try to change Bluetooth codecs, put all of bluetooth related apps and services out of battery saver but nothing resolve this issue.

Are there anyone that faces the same issue?

Could anyone help me?

Thank you so much 👍

Hello, on Mi3w Data(f2fs)

First I installed rom, then wipe cahed and dalvik, then reboot to recovery.

Next I tried "BiTGApps-arm-10.0.0-v0.6_signed.zip" but failed sdk version.

Then I tried "open_gapps-arm-10.0-pico-20201204.zip" and no errors at first try. so I wiped cache and dal and reboot again then flashed "Magisk_20.4"

And boot to system.

Reminder, skip pin entering after selecting 3 lock options. face unlock feature crashing and will NOT end SETUP.

BTW this is Great! Thanks! my first exp on AndroidQ.
[Mi 3 Android Development] CarCE12:
Now I tried

flashing Rom and Gapps(pico) then Wipe Cache and Dalvik

then reboot to recovery then flash Magisk 20.4

(Optional Reboot to recovery I wiped Dalvik, Cache, Data, including Internal Storage.

Then I reboot to recovery again, because my recovery setting will reset after wiping internal storage)

Now reboot to SYSTEM

SETUP REMINDER! (My Mi3w) Face Unlock CRASHING and will NOT end SETUP.

To be safe I did (no sim inserted) Skip Data and Wifi.

Selected "FaceUnlock+Pin" (DO NOT ENTER PIN) "Skip" setup everything later.
[Sony Xperia XZ2 Compact Questions & Answers] Henrikndk:
This is my 2nd XZ2 Compact and I'm generally very satisfied with this device. However I've encountered an issue with the preinstalled Mail app. Last week it stopped syncing and I was unable to find out why, as it worked fine on my Z4 Tablet. It just kept saying that it couldn't connect to the server. After several attempts to enter the incoming mailserver name, password etc to make sure that this was not causing the problem, I decided to just remove the account and then re-enter the account details.

Now here's the problem as it keeps telling me that the account that I'm trying to enter is already there?? And if I do long-press on the icon it shows the account but when i select it, it shows the guide to enter a new account??

What to do? I've cleared cache but I'm not able to delete user data (greyed out).

I'd like to avoid resetting the phone, but if that's my last chance, then...

Unfortunatley, after installing you have go into recovery before your phone gets the chance to reboot into system, which (as far as i know) can only be done using the hard keys, otherwise its gonna "fix" itself by restoring the stock version.

Hi everyone

My tilt has very poor signal when using the wifi. Is this normal? At best I get 30-40% signal strength. Ive tried several routers (home, work, Starbucks) and its always very low to no existent. Even when 1-2 feet away from the router the signal doesnt improve. People in the ATT forum had mixed opinions. One person said its normal, others said they have no signal problems. Ive tried moving to high performance (power mode) but no change.

Any ideas. Could my device have a bad wifi chip?

Thanks
[Tilt, TyTN II, MDA Vario III General] kareeem:
It's not your Tilt, it's all our Tilts that do this. The Titl doesn't have a dedicated wifi chip so it's not as strong as that of a laptop's. The only thing you can really do is slide the slider in start>settings>connections>wireless>power mode from best battery to best performance.
