Many thnx for the update.

Only the config will not update, gives a error.

I have a Zeniss model name: 801T3-2G32G.

Exactly the same unit as in this threat.

I am having difficulty with the translation from Russian, but there appears to be a problem with or at least confusion surrounding the 1 May and 2 May firmware updates, so I am holding off on those for now. While the previous update did not fully implement Bluetooth, it did address most of my other concerns, including:

The update defeated the dimming entirely, but the "Panel Learning" screen allows it to be reset. The combination of the hardware dimming when the vehicle lights are on and the Twilight app gradually dimming when the sun sets is perfect.

The firmware update fixed this for the steering wheel controls and the "Key Learning" screen allows this to be set for the hard buttons to the right of the screen. Here is how I have it configured (the up and down mappings are somewhat counterintuitive):

How to fix bluetooth can't connect any device?
[Android Head-Units] Spymate:
There is no fix.

Open the BT and try to add device.

Have you found a way to root it?

Hi.

I have the exact same unit (the exact same report from the hardware info app) but I hate de boot animation (The boot logo can be chainged but personally hate the android logo when booting...it just does not fit my car) so I need to root it to be able to change it.

How to Root

Hi Rob,

I have the same problem with Tom Tom Go Mobile but i'm not able to get the system root'ed can you explain to me how you did this? Because on different forum i found that you have to change the serial number of the device to a maximum of 12 characters to have tomtom go connecting to the tomtom server.

I would also like to know that, but you know, chinese people............................................. :rolleyes:

1 thing i know, there is a schut-down delay :good:
[Android Head-Units] bjmsam:
Among the improvements I have noticed in this firmware update are:

1. The volume issue has been corrected (levels below 7 now attenuate properly).

2. My phone is connecting reliably (so far).

3. Music player resumes last song played (and at the same place in the song).

4. "Fast boot" has been enabled (suspend for up to 2 hours).
[Android Head-Units] Spymate:
Confirmed.

The BT module is updated. Connection is better and faster download.

Music player also gives the correct mp3 tag information.

strange bootdisk behaviour

OK just created an sdcard bootdisk for the December firmware using Phoenixcard. No problem.

Put the bootdisk into headunit and rebooted. No problem, the unit eventually rebooted to a new 'updated' homescreen, and seemed to have updated OK.

Removed sdcard inserted another sdcard with June 'os_update.zip', and unit asked if I wanted to install. So I said Yes.

Then the unit starts updating (android robot with gears animation), and at about 35% it hangs. So I remove all sdcards and reboot - and it boots into my old installation!

So, it looks like the December firmware is simply running from the sdcard rather than installing! Any ideas what i'm doing wrong??
[Android Head-Units] Spymate:
Why did you make a bootdisk ? A bootdisk is not the way to update.

Just boot you's unit, then insert the USB of SDCard and update.

This is a link with all the update from december: https://yadi.sk/d/07ru92rb3HEh73/Allwinner%20T3_P3

The update can take a while, mine takes about 10 min.
[Android Head-Units] richdavislangdon:
If the firmware is prior to December you must make a bootable disc from an image to make the update to December. When December is installed updates can be made in the manner you have described. Earlier posts in the thread outline this procedure.

Anyway I solved the problem. I was selecting the 'live' boot disc (!Startup) option rather than the option labelled "product" in PhoneixCard. Done now and worked fine. Then I was able to update the June firmware by just copying the zip folder.

June firmware is a big improvement to the November version I was on before.
[Android Head-Units] Spymate:
And another update.

Date 14 Jun 2017

Changes, i don't know, sorry.............

The updates are nice but they don't update the security patch. The patch is from 01 dec 2015, in all the versions :mad:
[Android Head-Units] bjmsam:
That the security patch has not been addressed is disappointing.

My head unit is working so well after the 9 June 2017 update that I am reluctant to install more.

It would be extremely helpful if those who do install it would post here a description of any discovered changes.
[Android Head-Units] Spymate:
I'm going to install it tomorrow.

I'll see if I can find improvements.
[Android Head-Units] Spymate:
Installed the latest update but I can not see any changes.

However, I got a feeling that the radio has a better reception. I've compared the apps but they have the same version number ????

And for me the Overview button now works. I can see the apps that i worked with.

I think that the changes is in the system itself.
[Android Head-Units] ididnotgetabetterid:
Hi. I've been having this android player since December last year and have had many bug with it. My radio never worked, it used to restart with blank screen. It still doesn't work properly but these updates have helped a lot. I'm currently on the 9th June version which seems pretty stable to me besides the radio reception. Read somewhere that one of the red cables is mixed up so did a diy and swapped the cable works a little better now. But my player restarts completely when I crank the car. Can anyone give me a detailed explanation on how to sort this out? I have changed the time to 10 mins but it stays on in att mode but the moment I start the car it restarts. Besides this it any solution to the radio reception issue? Is there anyway I can boost the reception?
[Android Head-Units] ididnotgetabetterid:
Update.

The latest update seem to have made it worst for me. Only thing marginally better is the radio reception but it is till not upto the mark.

The dpi has gone bad. Everything looks very big. Also strangely the mcu shows updated but os has downgraded. I remember updating with the correct file.

Update : my bad. I did not update it completely. Pulled out the memory card before the android logo and flashing was done. Probably that was the reason for downgrade. Now it's successfully upgraded to latest version. I have a box (recent apps) in the top right corner now.
[Android Head-Units] bjmsam:
Your vehicle's battery is unable to supply enough voltage to the head unit when the starter motor is cranking. You can either replace the vehicle battery or add a battery pack for the head unit as described on the first page. The problem is not specific to this head unit; a sufficient voltage drop will cause most head units to reboot.

BTW, my FM reception has been fine regardless of firmware revision; I currently have the 9 June 2017 version installed which works well (and offers a setting for screen size).

[Android Head-Units] elBradford:
I grabbed this unit and I'm pretty impressed by it.

Since it's possible to tether android phones together using Bluetooth (to share internet), and since I'm already tethering my phone to this head unit for audio streaming, how would we go about allowing the head unit to use a paired phone's internet connection? Normally there would be some bluetooth settings to set that feature, but they kind of gimp the settings for this device and there are no bluetooth settings that I can see. Anyone know of a hidden menu so I could dive into Bluetooth settings?
[Android Head-Units] Spymate:
ehm, what do you mean ?

You already using the phone's internet over BT, right ?

Or are you only streaming from your phone ?

I'm using my phone's wifi tether (hotspot) for internet. This works great.

There is no hidden menu.
[Android Head-Units] elBradford:
I'm talking about Bluetooth tethering, not WiFi tethering, in order to provide a data connection to the head unit. It's possible, and ideal for those who are already automatically connecting via Bluetooth for audio.
[Android Head-Units] oerli:
This unit only supports wifi, use your phone hotspot. I would like usb tethering. Also not possible.

BTW, I got navi voiceover working by setting the gain for navi to Max and All the others very low, around 4. Of course no more very loud music, but at least they got the principal working. Problem now is that I have no more navi sound when not using the voiceover function, sigh...
[Android Head-Units] elBradford:
Why do you say that? Source? Of course this unit is capable of at least usb tethering, and very likely Bluetooth (unless they have a severely gimped Bluetooth radio inside). It has the hardware and OS support, it just needs the firmware or software to allow it.
[Android Head-Units] oerli:
Let us know if you find the firmware!

I played around installing usb driver for tethering, but that is not enough to get it working, I gave it up.

[Android Head-Units] elBradford:
I'm going to try and reach out to the Chinese devs, maybe go on the Russian forum and get some support behind the improvement. The devs seem pretty open to our inputs, but I don't think they look at this forum much.
[Android Head-Units] bjmsam:
Great! I hope they implement the suggestion you posted in the Rav4 thread:
[Android Head-Units] elBradford:
Me too! I'll bring that up. The problem I am having is that when cranking, it apparently drops the battery voltage too low to keep the head unit alive so it doesn't matter how long the head unit stays alive. It dies every time I crank.

IMO, that's a pretty silly oversight from the engineers of this thing. There's NO reason the 10V or whatever is available during cranking isn't enough to keep this thing alive. Unless I'm missing something significant, it would have been pretty simple to design the power supply to separately power the CPU from the amplifier and only power the amp when ACC is on. Unfortunately, I doubt this could be fixed with a firmware update, though I could be wrong. I haven't cracked mine open.
[Android Head-Units] bjmsam:
I agree and had to work around the same problem, but others do not encounter it, so an old battery is likely the culprit in my case, and perhaps yours.
[Android Head-Units] Dhamara:
Fix

FIX by update img 20161224 through the second sdcad slot

:good::fingers :laugh:
[Android Head-Units] bazanovv:
Restart at car carnking is fixed in the latest MCU code update 20170715 from Marubox by altering the off voltage treshold. Works only with the latest June 2017 Android firmware 20170609 (or 20170614) and "Sleep mode" set in Settings - Settings - General - scroll to bottom. Sleep mode should be set after each firmware update / battery disconnect. Details on 4pda.ru forum.

New firmware installed and checked out. Looks good.

Confirmed I no longer have cut-out on engine cranking. Excellent work :)

Music application seems to behave better. It constantly crashed on the previous firmware.

One thing that I notice is that bluetooth now no longer disconnects on engine shut-off (because the unit remains on ffor the pre-set time). Any ideas how to rectify this?
[Android Head-Units] Spymate:
Damn, I have not installed it yet.

This is a serious problem.

I think this is managed in the MCU. I will try to update the OS only and not the MCU.

I will report the findings.

Update:

I have the version from 14 Jun and i have the same problem.

So it's not from the last update. I had not discovered the problem before.

This has to be solved in the MCU. Hopefully, it will be resolved in a new update.

I tried updating the os today and asks me to upgrade. No idea how to do this as no options appear? Any ideas anyone please?
[Android Head-Units] bazanovv:
If reboot and clicking on something, and then the OS in the list above does not fix this, you may try to start from flashing the December firmware (2016.12.24) from the bootable uSD card, and then upgrade to the desired version.

[Android Head-Units] bazanovv:
You may try do a factory reset before performing firmware update, it helps sometimes.

As a last option, you may try to flash december (20161224 (Декабрьская)) firmware from the specially formatted bootable microSD card. You have to format uSD card with Phoenix tool (included) and write firmware in the .img image to it on special hidden bootable partition. Then you have to put uSD card in uSD slot and power the head unit on. Only one of the two uSD slots is bootable. Manual and video is included with the firmware. After flashing the december firmware you may try to update again. Don't flash the MCU firmware, only the Android one. Detailed flashing manual (it do have some caveats) available here, use Google Translate on it: 4pda.ru/forum/index.php?s=&showtopic=806442&view=findpost&p=61410096

PS Please remember, that each and every flashing firmware is a risk, and your own risk only. No one is responsible and nobody will help you, if your DVD will turn into a brick as a result of unsuccessful flashing.

Pleas look at the audio DSP pdf - TDA7719 (tda7729 really installed, it is mostly pin-to-pin compatible). It has only 3 frequency bands actually, low, middle and high frequency. That's it. Multi-band equalizer is a marketing fiction, nothing in this head unit out of the box can really modify multiply frequency ranges. The same is the sad true for the most of the head units in the market. You may try to get root and install Viper4Android for Android-produced sounds, but for the Radio and DVD sound you may use only the default EQ. And, even more, this EQ app do not modify sound in any way, it only says the MCU to configure AudioDSP to alter sound this way and that, and to set the volume, balance, and switch the inputs. EQ app works like a remote control of your TV.

Most problems with GPS signal on this head units are caused by the bad / broken GPS antennas. If time and timezone is ok, head unit do have an internet connection for A-GPS, and you have already tryed switching from GPS to Glonass and back to GPS to re-initialize the GPS module, it's time to replace the antenna module. It may be with the FAKRA (blue) or SMA (gold) connector, and should not cost much. Sometimes front windshield glass heating wires does not let the antenna to work properly, so you may try to temporary move antenna out of the car. Some people do report success then shaking and striking the antenna slightly. More info here, use Google Translate on it: 4pda.ru/forum/index.php?showtopic=806442&view=findpost&p=63783521

It seems that yes, MCU (and Android too) from this firmware branch should fit ok https://yadi.sk/d/07ru92rb3HEh73/Allwinner T3_P3 Version numbering and names and models are all the same. However, please remember that each upgrade is a risk, and your uwn risk only. Unfortunately, there are no way to recover from the dead/flashing failed/incompatible MCU.
[Android Head-Units] no010:
Current soft in my radio has bugs and crashes.

So there is a risk that the soft will not be ok and the radio will be thrown out. :rolleyes:

Can't get back to original version? :confused:
[Android Head-Units] bazanovv:
As far as I know, firmware downgrade is not always successfull, and you need to have an old firmware (os_update.zip) at hand.

If you wish to downgrade, you may flash old December (2016.12.24) version firmware from bootable MicroSD card, and then upgrade to desired version, if you have one. And, please, don't downgrade MCU if not extremelly needed. Most times old Android code will work with never MCU code just well, and vice versa. Only new features, like sleep mode, will not work.

Most user-visible problems are in the Android code. MCU is responsible for volume control and EQ, audio/video inputs switch, radio tuning and RDS, power on and off (and sleep), steering wheel buttons and CANbus control and so on. It is a hardware thing, and it usually works more or less ok (with some bugs, huh).

If Android / applications frequently fail, especially at high load, and Android upgrade does not help, you may suffer from CPU overheating. Under high load it's temperatute may be 110 C and even more, higher then rated temperature in PDF. Use CPU-Z or other tools to check. You may need to install additional heatsink, fan, or, better, make a bottom cover to work like a big heatsink then. Install some metal piece (about 6 mm high) and thermal pads between the CPU and the bottom cover. This will drop temperature to acceptable 65-75 C.
[Android Head-Units] no010:
I updated the radio and everything is ok.

The info on the device changed only mcu version.

Doesn't work after updating google maps :(

Maybe You know why?:confused:
[Android Head-Units] bazanovv:
You may try to update Android on the Head Unit via the "os_update.zip" to the latest 18.07.2017 firmware as well. It may (or may not) fix some problems.

Btw, I don't understand, what happened - Google Maps stopped to work after update? What happens, then you start it? Have you tryed clearing maps application data and cache? As a general workaround, find an older version of Maps .apk, install it manually and disable autoupdate.
[Android Head-Units] no010:
I've removed the updates and google maps works.

The processor temperature shows 61 C. That's ok?
[Android Head-Units] bazanovv:
Latest working version of Google Maps for this head unit is V9.46.2 https://google-maps.ru.uptodown.com/android/download/1467151

CPU (SOC) temperature is quite high for all Allwinner T3 head units. PDF says about 85 C max (auto and industrial termal range), however, real silicon crystal temperature may rise under heavy load up to 105..110 C, after that head unit may experience glitches and restarts. It will be very good to install additional heatsink on the CPU, or fan into head unit. Personally I prefer to install thermal pad and stack of coins as the termal interface between CPU and head unit bottom cover. Bottom cover used as a big heat sink then. You may find photos and manual, and links to other solutions here.
