Good morning, i've a big issue with my dasaita PX6 (android 10) after last official ota update HA3_rk3399_10.0_ota(20210722).

I updated my device putting "update.zip" on my pendrive and everything worked fine, but now i can log in in my Google account and all gapps won't work (don't start at all, freeze on boot logo). Only Gapps, in particular Youtube, Play Store, Gmail, Gboard, Google Search, Maps.

I control in my app list, and i haven't Google Play services. I installed it manually from apk, but everything still don't work.

How can i solve this problem? I thought to root the radio and flash open gapps with flashify, but i don't know if it's work properly replacing the installed ones. My MCU is 3.71_d, if i update it can i also solve?

Thanks all!

OK grazie, lo farò appena possibile.
[MTCD Android Head Units General] lim-popo:
Make factory reset... It will help!
[MTCD Android Head Units General] Ryckylyck:
Do it 2 times, from recovery and from settings, but it's the same! Google play services disappear every factory reset 🤔 It's like miss it in this rom and every gapps don't work at all
[MTCD Android Head Units General] lim-popo:
You said OTA... Try to download and copy it to your memory stick, then install it via Recovery
[MTCD Android Head Units General] Ryckylyck:
Thanks for your answer!

I downloaded update here: https://www.dasaita.com/blogs/news/update-firmware

I inserted file "update.zip" in a pendrive and from recovery I click "apply update from USB".

Where can I download same rom not "Ota update"?

Try this one...

[MTCD Android Head Units General] Ryckylyck:
Thanks a lot, I'll try! The procedure is the same like before right?
[MTCD Android Head Units General] lim-popo:
Yep!

But try to take 8Gb memory stick (just suggestion)
[MTCD Android Head Units General] Ryckylyck:
Update:

I tried but it still the same, Google play services is not installed and all gapps don't work. So I decided to download manually Google Play Services apk and install it; then with "ES file explorer" in root mode, I copied gms folder placed in /data/app into /system/app with permission "rw-, r--, r--".

Now Gapps seems to start, but I can't add a Google account yet. I read about folder /system/priv-app but I don't know if it's work.

Before manually cut folder into /system/app I tried with "systemize magisk module" but when I write su-> systemize on terminal emulator, it says "systemize: command not found" 😪 Why? Can I solve? Maybe enable execute permission can I solve anything?
[MTCD Android Head Units General] lim-popo:
1. Did you Root your device? (Can this be the issue???)

2. Try MicroG to run Google account
[MTCD Android Head Units General] dasaitamax10:
Thanks suchar20 for your advice .. I downloaded your file and copied it from a compressed folder to a 16gb stick, and I was able to install the new MCU version .. How strange the usb sticks .. I used the 32 one and I could not install the 16gb one without problems instead .. Thanks a lot for the availability and the advice .. Despite the MCU update my problems with the steering wheel buttons still remain .. I can no longer have the functions with the car radio and steering wheel buttons .. I think I have to install the previous version .. Thanks for everything ..
[MTCD Android Head Units General] suchar20:
And in what car do you have this radio installed. Maybe your CanBus settings have changed after updating the system software and MCU. Go to Settings> Vehicle> Factory Settings. Enter the code 126 and confirm. Set to CanBus and see if you have the correct car model set. My Toyota C-HR is 08.
[MTCD Android Head Units General] lim-popo:
​

suchar20 is right but be aware not always your Canbus will correspond to your settings. For My Citroen DS4 the correct settings for Canbus is Peugeot 204​
[MTCD Android Head Units General] dasaitamax10:
Hi guys, I take the opportunity to answer both lim-popo and suchar20, and thank you for your availability .. I am quite practical to go into the settings of the car radio, by now it is more than a week that this car radio haunts me, I have tried in all ways, but nothing to do .. My car is a peugeot 2008, until recently before installing the latest update 20210722 the car radio worked fine without any problems .. Unfortunately for me I am having problems with this latest update only with the functions buttons on the steering wheel .. Every now and then when the car radio "wakes up" it allows me to use the functions of the buttons, in a nutshell the car radio decides .. In my opinion there is some bug in the update .. Anyway tomorrow morning I reinstall the previous version I had, and it ran great .. Anyway, thank you very much for your support .. Hi guys, hello ..
[MTCD Android Head Units General] Ryckylyck:
SOLVED!

Thanks for your support lim-popo, now my Dasaita have again google services! I manually moved Google play services' folder from /system/app to /system/priv-app and i authorized it with rwx r-x r-x permissions. Now i've again account google, play store and assistant! I attached the Google play Services apk worked for me.

Now it remain a little problem: assistant don't call with phone. When i try to say "Call Riccardo", it says me "Sorry, i don't understand"... Other commands work very fine, like "bring me to home"! Only phone calls with voice commands don't work, i don't know why, but i will solve it this too!
[MTCD Android Head Units General] dasaitamax10:
My car is a peugeot 2008 always working with the settings managed by canbus ..
[MTCD Android Head Units General] dasaitamax10:
Hi suchar20, as I have already told you my car is a peugeot 2008 and it has always worked with these functions that I show you in the picture .. Today I have installed previous version of the update .. 20210507 works very well without problems, "for now I hope for always "thanks and greetings ..

Problem now looks not just update.

The unit is not response to any usb.

Sorry if i am asking stupid question, but Is there difference between update and orginal MCU?

Because i want to reach to any installation point or progress.
[MTCD Android Head Units General] Pavel-71:
Upgrading the MCU will probably be different from the original, you can try downgrading to an older version. But first you will solve the problem with the screen, maybe it will also solve the problem with USB. Try another USB or microSD. The last option is SOM:

How to downgrade???

If you have software source pkease share.

Dasaita website has nothing
[MTCD Android Head Units General] suchar20:
Hello saady002000. I described the problem with the white screen in this forum thread. It is difficult to do anything on a white screen. Therefore, the best solution is to connect via HDMI to a TV or some monitor and then the correct image will appear on its screen. (this was the case in my case). When you have an image on the TV screen, you can easily update to older versions of the system or MCU software by clicking or sliding your finger on the white screen of the radio. It is also a good idea to perform a factory reset of the radio. Regards.
[MTCD Android Head Units General] suchar20:
The dasaita software is at this link. https://www.dasaita.com/community/forum/topic/36770/firmwares
[MTCD Android Head Units General] saady002000:
Hi friend,

Thank you for help.

I connected my unit to TV, system is working and i can update ot restore but still white screen.

Does this means screen damaged and have to repace?

Now i do not know what to do

Kindly check photos and advise
[MTCD Android Head Units General] suchar20:
Hello . Since there is a picture on the TV, the radio is good, only some radio display driver is wrong. It happens when we upload the wrong software for a given radio model. On this forum page 10 entry # 196 I described how I got rid of this white spot. Some users managed to fix this via screen13. When updating MCU to pendrive you need to put two files. dmcu.img and dmcu.ext from screen13. Read this forum thread from my post # 196. Check in the settings what your radio parameters are. If you have px6, rk3399, 1280X720 then this attached dmcu.ext file will be the right one. However, the decision to upload is yours.
[MTCD Android Head Units General] saady002000:
where exactly and how to enter this code i opened car setting but do not know where or how to write it?

sorry i am not expert in that but can you send more details
[MTCD Android Head Units General] saady002000:
I connected it and got screen but still white.

But now i can access it

Can you pleaee tell me how to enter this code??

Where exactly??

I opened car settings but do not know where to write this code
[MTCD Android Head Units General] saady002000:
Hi friend thanks alot.

I did that but still have white part.

Do u have idea how to remove this white part.
[MTCD Android Head Units General] suchar20:
Now this white spot will disappear by itself as the radio is on for a longer time. And the code is entered by going to Settings> Vehicle> Factory settings and here you enter this code and accept it, but it probably is not needed anymore.
[MTCD Android Head Units General] saady002000:
Thanks alot my brother.

I reset factory setting and it gone already.

I will fix in car soon.

Thanks for all friends here for your ideas and support.
[MTCD Android Head Units General] suchar20:
Congratulations on repairing the radio. Now it remains to be installed in the car and enjoy its use. Regards.

Hi friends,

First of all thanks to all for ideas and support.

I am writing this post to tell you briefly about my experience with my Dasaita max10 px6 android 10 unite update.

I tried to update this rom via USB, added only Update zip file and MCU file.

Then unit hang up and gave a white screen.

Tried to update again but could not because cannot see.

Then tried factory reset from reset button but again only white screen.

I contacted dasaita team the provided me last update zip file qnd mcu file as well.

Android 10 Update MAX10 Version：HA3_rk3399_10.0_ota(20210722) https://www.dropbox.com/s/kaazivfzcef9wb6/HA3_rk3399_10.0_ota(20210722)升级包.zip?dl=0 MCU : 3.78 https://www.dropbox.com/s/3hd3ci3rp07ddnt/dmcu.img?dl=0

but still white screen is problem

After that friends her advised to connect to TV via HDMI and use both MCU and DMCU.ext files along with Update zip file all on same formated USB.

Thanks God. This time worked and screen was white at beginging then started to go normal after while.

I did not wait much and applied factory reset and then updated only MCU file which Dasaita team prividee and it was good.

Now it become perfect.

Photos attached for almost all stages.

Again thanks to all here.
[MTCD Android Head Units General] saady002000:
Thanks Suchar.

Now i will try to see how to retain steering wheel control before install this time.

Because my car has no canbus and only one set of steering wheel controls works.

Key1 not working but key 2 works.

I tried to use ASWC-1 but did not work then just programed one set if keys for audio controls.

I ll try to find solution for this issue one more time.

iF any ideas please share.

Hello gentlemen, I just managed to get my 1920x720 dasaita equipment on a monitor, I put an MTC that was not yours and it gave me an error on the screen (see photo)

when connecting to an external display via HDMI.

I was able to change it thanks to a post from a fellow member of the forum, I started with a resolution of 600 and I changed thanks to you with the files dmcu.img and dmcu.ext.

The screen is still blank, I am attaching photos I don't know what to do to fix it, and I've seen something around here, enter a code instead of 126,

If you can tell me what it is or some step to make the screen well, thank you.
[MTCD Android Head Units General] suchar20:
Hello. Since you have an image on the monitor, and the radio display does not have it, start by restoring the factory settings of the radio. What's that 1920x720 resolution?
[MTCD Android Head Units General] saady002000:
Now you can reset factory setting from factory reset button.

Press for 3 to 7 seconds till lights blink.

And wait till it complete reset action.

Or u can connect USB includes ( update zip file, DMCU.img file, and DMCU.ext file)

It will boot and can update.

Good luck
[MTCD Android Head Units General] rudyboler:
Well gentlemen, this is going little by little, I have almost the screen, but it is not all right, then when I hit the touch if I move to the right goes to the left, I mean the other way around, and so on, I imagine that I will return little by little, I have gotten into car settings, but It does not allow me to put the touch that appears on the screen to calibrate it +1 and then +2, the color looks very bad on the screen, and on the monitor when I touch something it stays like when you are going to send a marked file (I leave you the photo of the monitor) I do not know what it will be, to see if it returns little by little to your site.
[MTCD Android Head Units General] saady002000:
Did you added dmcu.ext file??

Or not updated yet??
[MTCD Android Head Units General] rudyboler:
If I did, I put the MTCE_HA3.78_1,

But look at the screen, in the end I'm going to have to put it back in again or what do I do?

I was wrong and I put it back, forgive me.
[MTCD Android Head Units General] rudyboler:

Format your USB first.

And copy following three files to it:-

1-Update.zip

2-Dmcu.img

3-Dmcu.ext

Then connect and update.

It sha work and colors will take little time to come back to original.
[MTCD Android Head Units General] rudyboler:
Okay, you can give me the link of the files that I don't even know where I have them, thanks.

Ok, I have the last dasaita I imagine it will be to install it again by usb, and the dmcu.img but there are two files, before you disjisted three, the dmcu.ext is missing, which I imagine is mine 1280x720, then I put the three files in a usb or I go one by one.

[MTCD Android Head Units General] rudyboler:
Ok thank you, I look at it and tell you something, thank you.
[MTCD Android Head Units General] suchar20:
So you don't update the software as you write. Correctly, you need to format the pendriv and upload only the system software to it, only the update.zip file. Then connect the flash drive to the USB of the radio and perform the system update. After updating the pendriv, reformat and upload the dmcu.img and dmcu.ext files to it. Reconnect pendrive to USB and perform MCU update. By updating this, we avoid potential errors.
[MTCD Android Head Units General] rudyboler:
Ok according to the compi suchar20 says to update the image first in usb formatted to FAT32, and then when it is finished reformat the USB and copy the two files .img and .ext

and update the MCU, I think I got it, thanks

So I will and I tell you
[MTCD Android Head Units General] rudyboler:
Good gentlemen, thank you all for helping me, I will explain to you it already works, I will leave you some pictures, the Chinese (Seller) sent me two files dmcu.ext (screen: 13) and hct.aut (empty), format the SD card to FAT32 and I put them in, I put it in the SD slot of the device and when I started it I caught it alone, without touching anything, the screen put screen: 13, until it was installed and it was fine, thank you very much everyone, greetings.

Impossible to find a reliable site for updating my dasaita ....
[MTCD Android Head Units General] rudyboler:
You have to download the file that is posted on post316, format a usb in FAT32 and unzip the file and put it in that usb, change the dmcu to your screen resolution, now you put the usb in the device and start the multimedia and he will only take it and the screen will be fine.
[MTCD Android Head Units General] Uthopia:
I redid the update as specified in the previous posts but still no better, I still have either a white, black, or degraded display. I also tested the two link files allowing to modify the resolution but still not better.
[MTCD Android Head Units General] Uthopia:
I put the screen in 13 using the .auto file

I got a single display that's already it, however the colors are bad as in the photo. I don't really understand where this problem comes from ....

In case of an OTA update, at startup, do you have to click CLEAR AND FORMAT FLASH? Someone does it, someone does it ... When does this suggest? Reason why I plan to go to the latest update is because during calls my microphone works weird sometimes others can't hear me properly. They complain about low volume and faded voice.
