Android 8 fails to load

Thanks for your answers fokos and k3dar7.

I have tried with update.zip file and update started. Thats the good news. Bad news it is not finished and now I need more help :(

There was info that update is available, I marked I want to install it and I marked "wipe (something) and flash". System rebooted and then it stoped on screen with car logo. After few minutes I saw Android recovery screen. I tried few times "try again", then few times "factory data reset" both with USB drive connected and without it and result is always tha same (Android fails to load and after few minutes I see Android recovery screen.

Before the update started I had Android 8.0 without any udates so probably 8.0.0, dated for 2017.

I tried to use updated file dated 09.08.2018.

I had problems with my unit for last 2-3 weeks (that is why I started to look for updates), but it always managed to load the system after restart.

I have no idea what is my model number and now I am not able to check it :(

I wanted to paste link to product offer with this unit but I am new user and can not do it.

I bought it on aliexpress, product name is "Car 1 din Android 8.0 GPS for Peugeot 2008 208 Autoradio Navigation Head Unit Multimedia 4Gb+32Gb 64bit Android PX5 Octa-Core". May be when you see it you know what model number it is.

I wanted to paste here the picture of my Android recovery screen, but again I am not able to do it. The only thing I can do here at the moment is writting so I will write all info from the screen.

[MTCD Android Head Units General] :
From recovery try system update- choose usb drive- than flash again.

If recovery mode not mount the usb drive, if you can not update from the usb drive, put the update.zip file on the sd card and try again, choose system update- from sd card- and flash it.

It happens to me this error when i flash a MX rom from system update, after that i flash it from recovery.
[MTCD Android Head Units General] Blue GL:
There are only "Try again" and "Factory data reset" on the recovery screen. Nothing more to choose . Is there any other recovery I can enter somehow?

I have no SD slot in my unit, so I can only use SD card with USB adapter, but this will be probably recognized as USB drive. Anyway I will try.
[MTCD Android Head Units General] :
Seems to be a type of update fail mode, and not the real recovery mode. Try to get into recovery mode.

What manufacturer is your unit? What MCU have it?

Now you flashed a HA-dasaita update rom? When you choose try again from that recovery is not finding the system update from the usb drive? I see the error is failed to mount the sd card, but you don't have one.
[MTCD Android Head Units General] finkeo:
Try formatting the USB flash drive as FAT32.
[MTCD Android Head Units General] Blue GL:
It is DASAITA. I have found two symbols on the box - may be one of them is a model number...

* AW-HA-RS4755

* HA5404-V840-8 or HA*404-V840-8 (it's handwritting and I am not sure about third sign)

When I choose try again it is not finding system update from USB. THe procedure is the same as recovery from a fail without update involved but at the end it is not succesfull (restart, start up screen with "Multi-media on-vehicle Navigation System" for c.a. 10 seconds, then car logo for few minutes, black screen for few seconds, again start up screen with "Multi-media on-vehicle Navigation System" for c.a. 10 seconds, finally Recovery screen).

I tried both USB drive and USB adapter with micro SD card - no fifference.

In my opinion this recovery doesn't look for external data, it tries to recover from unit drive. I am afraid that some files were arased at th begining of update, then update failed and no new files were saved :(

Is there something like bootable system instalation which can be started from USB drive?
[MTCD Android Head Units General] finkeo:
The info provided during the failed update suggest that the USB drive is NTFS.
[MTCD Android Head Units General] Blue GL:
USB is FAT32. I think car unit may be ntfs.
[MTCD Android Head Units General] :
That is not a full recovery mode. Try to get into recovery, press the power (or reset) button until the lights start flashing, than release and press again short 2-3 times the power (or reset) button.
[MTCD Android Head Units General] Blue GL:
I entered it once some time ago, so I am sure I'm doing everrything properly, but I can not enter it :(

I entered it before from loaded system... about 10 sec push reset until panel flashes, then for 1 second and shortly fird time...

now I see start up screen "Multi-media on-vehicle Naviation System" and then it should enter recovery mode and I should see that full recovery screen, but now I see this start up screen and then factory logo so unit tries to start in normal mode and then finally I see that shorten recovery screen :(

I will try to enter it again tomorrow. Good night to all.
[MTCD Android Head Units General] Blue GL:
Success!!! My "brick" is alive again! :victory: :highfive:

Thanks for help.

Entering fuul recovery mode is not easy when your system is not loaded is not easy.

For sure it is ipossible from simle recovery screen. I think it is also not possible from start up screen. I managed to enter it twice, both times at the moemnt when car logo was presented.

At first I tried to update to the latest version. Update file was accepted, everything was patched but after reboot the system was not loaded.

Then I thought that may be there is something wrong with the update file. I downloaded older version from 13.04.2018 - link is not active anymore here, but some time ago Chinesse seller sent me that link by email. that older update worked :)

Now I am afraid to try again with the latest update... may be the links in this post are not good for my unit... what information about my unit is needed to define if this software os good for my unit or I need another one?

Its PX5 branded Dasaita without ohisical buttons. 4GB+32GB, Octacore, Android 8, no phisical buttons.

Where can I find model number?
[MTCD Android Head Units General] typos1:
You dont need a model number - if you have an MTCD or MTCE MCU and an RK3368/PX5 processor running Oreo you can use ANY MTCD/E Oreo ROM, from any MTCD/E manufacturer - there are about 20 manufacturers making these units and they are very, very similar, so similar that ROMs are interchangeable.

So try downloading the ROM again or another MTCD/E Oreo ROM.
[MTCD Android Head Units General] :
I think your download was broken-corrupted, use 7zip for unzip the archive. I have installed the july update and works fine, i don't tried yet the latest update.
[MTCD Android Head Units General] Blue GL:
Few comments earlier somebody asked me what model number I have, so I thought it was important and asked how to check it :)

- Now I ask how I can check if I have MTCD or MTCE MCU? I have no idea what is the difference. Or may be it makes no difference and both types accept the same update files? I succesfully updted MCU using link from this post.

- I am sure I have PX5 with Oreo, no idea if it is RK3368 or knot.

AUX Connection

Hello folks,

I have a Dasaita HA2039-S720 Unit in my Mitsubishi Outlander III 2012 with Rockford Fosgate Soundsystem and there is one thing I can`t figure out.

Is it neccesary to connect the red and white cinch connectors from the main power harness with the red and white cinch connector from the other side of the unit??

I have sound without this cinch cables connected but for what reason do they have connected like it is shown in some tutorials?

I only have the problem that the canbus is not switching on the Rockford System at every boot. Most of the time I have to mute and unmute my device to get the Sound on.

I think that has nothing to do with the Cinch connectors.

Maybe some can explain me the use the red an white cinch cables and maybe some has a solutuion for the Sound Problem on boot.

Hello everyone!

I'm experiencing problems setting the steering wheel commands and some other things such the automatic doors lock based on speed on my Toyota RAV4, I've already tried to change the canbus settings, but this doesn't work..

With chinese manufacturers and sellers you'll never know if it is legit or fake, to be on the safe side, buy in the official Dasaita store in Aliexpress:

[MTCD Android Head Units General] Sven_-K:
If you buy at the original manufacturer, you have also mostly a better support.

I already have very good experiences with Shannon Liu from the official Hotaudio/Dasaita shop. Always friendly, always helpful.
[MTCD Android Head Units General] MaDence:
I'm sorry if this has been asked before. I just could not find a similar question.

Is there any way we can force the reboot of the head unit (Dasaita HA5290 in my case) whenever it goes into a non-responsive state? Is there any button that can be pressed instead of having to turn off the engine just to reboot the head unit?
[MTCD Android Head Units General] kind3r:
To each his own. I wrote to them for some clarifications regarding a unit on the 29'th of September, no reply yet. I ended up ordering from another store which replied within a few hours (waiting for the order to arrive).

Use the reset hole.
[MTCD Android Head Units General] MaDence:
I've been trying that reset hole but it does not work.
[MTCD Android Head Units General] typos1:
Try holding it in, Better still use [MENTION=5092263]Hal9k_[/MENTION]'s ROM - it has shut down/recovery/reboot options in a power button on the status bar.

[MTCD Android Head Units General] LRTan:
[MENTION=6942549]hotaudio[/MENTION] please add a reboot option so that we can easily reboot our units without having to turn off car engine or stick a pin into the reset button( a pain to do). At least with reboot option we can reboot the unit without having to stop the car. This is because sometimes all audio from my unit will cease to work, hardware buttons still work meaning if i tap on panel button there is a beep, but anything within the android system has no sound, i have to reboot for audio to come back up. Will post a youtube video on it when i get the chance.
[MTCD Android Head Units General] SkyBeam2048:
The Hal9k mod ROM does actually have a restart option. You might also go to system setting > car > factory settings and enter the password "hctreboot" to initiate a system restart. Well, still not as comfortable as an app click and certainly not something you should do while driving.
[MTCD Android Head Units General] LRTan:
Yeah, what i am doing currently is i saved the latest MCU update in the sdcard, and i initiate the MCU update when something like this happens. Takes 2 mins to update and it reboots the system.
[MTCD Android Head Units General] SkyBeam2048:
While this might sound like a smart solution it might actually cause the flash-memory storing the MCU firmware to fail prematurely. So I don't recommend this for day-by-day use.

After installing the unit, I noticed there’s an issue where google now can’t hear me but the internal mic works with everything else. I reported this to the seller and she recommended to download the latest Update version and also the latest MCU file.

So to make sure I am doing this right, can you tell me if these are the correct steps?

1. Download the latest MCU version 2.40.

2. Download the latest System Update px5_8.0

3. Put everything on a USB Flashdrive and zip the System Update, and unzip the latest MCU

4. Plug USB flash drive to the unit and they’ll install automatically?
