[Android Head-Units] Mr.TT_NZ:
@Bushido1992

That unit has MCU QF02.

I have seen others post units which have that but it seems agreed that those units are not of the same type as those we are discussing here in this thread and I have not seen any information as to which thread on XDA would be applicable to them.

Maybe someone else here can help though.
[Android Head-Units] Mr.TT_NZ:
I just tried the newly posted April firmware (thanks @Barykelo) and while I do like that old radio interface better and the 01010101 logo change still works they have deleted the only launcher that I liked. Also there is no change to the errors in the FM radio performance so I give that firmware a poor rating and will revert to the May one.

I actually think the radio problem will be in the MCU, I'm going to test some earlier MCU files to see if it is a relatively recently introduced issue, hopefully older MCU files will work with the new firmware to allow testing. The oldest I have is 20230217, does anyone have any older ones they could post please?
[Android Head-Units] Mr.TT_NZ:
Oops I think it is 20230207 not 17 that I have and yes I got it from your repository so I made a typo when naming the file, thanks anyway.

Please always keep the webshare going as although it is slow, it is reliable. Your efforts are appreciated!

[Android Head-Units] Mr.TT_NZ:
@molduo thanks for that but you have nothing older than what I already have for the BD37534 TSC4745 chipset which is what I am testing (maybe there is no earlier one in existence). A great resource though.

Installing the 20230207 did not change the error so the Chinese got it wrong all along. Hopefully the next release will have a fix (fat chance lol).
[Android Head-Units] Barykelo:
Not even a miracle will help you with this DSP and radio chip. Versions S1-S4 are useless. You must buy S5 and above.
[Android Head-Units] nyp42:
Why do you say S1-s4 are useless? I have an S2 and am looking for most recent firmware for it. Should I just not bother? What will happen if I try to upgrade?
[Android Head-Units] Mr.TT_NZ:
@Barykelo you may be correct but I don't have several hundred dollars to throw at buying one just to see if it is better (what if it is not?).

The features the S5 and above have (that would be unlikely to be used) come at a large price premium. The S2 has just the right price/feature ratio for most people here I know so it is such a shame that some incorrect programming lets it down. I buy these units to install in used Japanese import vehicles that come with Japan specific head units which cannot be modified, I've installed only one S2 so far and the user hasn't complained and I won't mention the issue to him.

I bought the second one for another person but decided it would not be a good combination of the fragile LCD and the person's poorly controlled mentally deviant son, I figured it would be smashed within a couple of hours so I kept it for experimentation and will pass it on to someone else one day. The previous units I got were Ossuret AC8227L systems and worked perfectly, I need to see if I can get more of those but these S series are what the seller now sells as the replacement.

BTW as I have mentioned before the BD37534 is NOT a DSP despite the claims by the sellers, it is a purely analogue device which has no graphic equaliser, only a bass/middle/treble boost/cut so all those pretty sliders don't do anything as there is no hardware for them to control.

The radio chip is quite capable, I have the datasheet and the programming guide, but somehow incorrect data is being given to it so wrong things happen. I'd be really interested to see exactly where that data is generated which I feel is in the MCU file somewhere so that it could be edited, are you or anyone here familiar with the make-up of the MCU file and what editor could be used to see into it? I did come across a utility called 'Hexwalk' that may have some possibilities. The small file size of the MCU amazes me considering what it appears to do.
[Android Head-Units] Barykelo:
If you have these BD37534 TSC4745 chips, the FM radio will always be bad and most DSP settings will not work.
[Android Head-Units] nyp42:
Ah, is that all. Those things have been an issue since day one on mine. I don't really listen to FM radio though so it hasn't bothered me much. So if I update the firmware to the latest I won't introduce more issues then?
[Android Head-Units] Barykelo:
There were audio issues when upgrading to android 13, but I don't own that version of the unit anymore, so someone else will have to confirm for you if that's resolved.

[Android Head-Units] Elrathias:
Solves alot of the "quirks" and weird behaviors that the early (green pcb) and first revision "black pcb" models had. 240110 and later also turns on the dual bluetooth options meaning you can finally use android auto AND a bluetooth obd2 reader etc.

Also loads of changes in the MCU to make the amplifier and DSP chips work better (no loud BOOOPS when picking up calls etc)
[Android Head-Units] Elrathias:
Sounds like you are outputting speaker level signal into an amplifier,go to settings -> factory -> power amplifier volume and lower it all the way down to -15, and see if you can increase the volume linearly then, atleast for a few volume settings.

If so, you need to locate your amplifier, and splice in a line level converter on the cables connecting it to the head unit.

OR

bypass it completely and feed the car speakers with the stereo output directly. I would avoid this since its probably a 8-10ch output amplifier that has hardware regulated volume matching on the different speakers to appear as a 4ch system. (think A-pillar and top ofdashboard mounted extra speakers)
[Android Head-Units] Elrathias:
Im starting to suspect that the fake android is mostly for play store/app compatability.

lots and lots of old torquepro plugin apps that wont install or even be able to sideload onto android version "x" or later etc.
[Android Head-Units] Elrathias:
To be fair, we want an android head unit because we tinker with stuff.

The vast majority does not "need" a stereo with always on LTE connection, that can run youtube or output spdif video to secondary screens. A linux/BSD based unit that runs way WAY quicker on WAYYY worse hardware is plenty enough.

However. The TDA7850/7851 amplifier chipsets on the are really worth it _IF_ you dont have a amplifier in your car already.

anyways, this is offtopic...
[Android Head-Units] ScorpionSX:
Could be that, but it's also definitely marketing. 99% of people who buy these units will never realize that it's fake, but they can brag about having Android 13,14,15,whatever version in their stereo...like that makes some difference. I would pay good money for an Android 8-9-10 unit that would integrate on OEM+ level with my car and have quality components in it and wouldn't make a beep about having old version on it. Is it stable? Yes. Is it running everything that a modern headunit is supposed to? Yes. Then who cares about the version.
[Android Head-Units] nyp42:
So what is the point of upgrading the MCU file to QF03 or QF05 anyway? I just flashed the latest Updat.zip file and not the MCU file and everything seems to work fine. I had upgraded the MCU previously but never beyond QF01.

So far the FM radio seems to work fine, seeming better than it ever has also DSP features like the EQ and base boost now have a very noticeable effect. Am I missing something here? Is there anything to be gained from flashing the QF03 or QF05 MCU?
[Android Head-Units] nyp42:
I have linked this comment in the original post for this thread as it seems to be a fairly complete and up to date collection of firmware and MCU files.
[Android Head-Units] j0hn83:
The Play Store/Android apps use the Android SDK/API number to determine what version of Android is being used.

Most units don't fake this because it breaks apps.

The faking Android version is for marketing.

Greetings everyone, this attached picture is of the xtrons device that I bought a long time ago. I had a problem with the motherboard and was unable to fix the device but I kept the screen and it works fine. I want to install the screen on my Hizpo and it has the same dimensions 1024 x 600. The reason for changing the screen is because the colors, clarity and brightness of this screen are much better than the Hizpo screen, I have attached the screen code, can anyone help me here in particular? My device is a 1024x600 7 inch S6. I will attach a link to the two devices on Ali Express.

[Android Head-Units] marchnz:
Avoid updating unless there's a reason to. Especially avoid MCU updates.

If you don't have the original ROM and MCU updates files, expect restoring will be very difficult if there is an issue (just read the many, many posts on these forums.)
[Android Head-Units] MauriBixio:
Holy words! ;)

We have written this many times, but many continue to update for no valid reason, often, and then perhaps only introduce new bugs with black screens...

Personally I'm tired of writing all this, so everyone can do as they want, and if they brick the unit... it's only their fault.

Thanks Barykelo.

This is my current version.

Currently I face problems with the following things:

1. The clock on the Convers+ stops working after ignition on the engine. The clock on the media is correct.

2. Sometimes the navigation ( Waze ) is getting crazy and start moving the car's icon outside the map

3. The Radio signal is week sometimes.

4. I'm using the max font size but still the text is small in my opinion.

Do you think make sense to update my version with the one you provided me?
[Android Head-Units] HellAn:
Hi, wouldn't it be best to make a poll that goes to the top of every post page or front page and lists the firmware versions from 2023-2024 where everyone states which one from who is the most satisfied ?
[Android Head-Units] Elrathias:
LOTS and lots of fixes to how the actual chips on the PCB are operated, volume gain and random BEEPs or POP's caused by source handover etc. highly _HIGHLY_ recommended to upgrade just for quality of life.
[Android Head-Units] Elrathias:
Sounds like you need a new car battery, the drain of starting the engine is probably causing the voltage to drop so low that the head unit resets itself.

potential causes of the bad radio reception and bad gps reception are ground cable faults OR you just not screwing them into the sockets hard enough. (the radio is a slot in though, so remove that and clean its surface with some very fine sand paper, dont grind the coating down though. just rought it up.
