@ikerg any thoughts on this? Much appreciated your reply.
[MTCD Software Development] Bettman66:
If you want to switch from different Android versions (A9, A10, A11), you always have to flash an image first.

Only then can they import an OTA for the same version.

Try SDCardTool or USB-A method and flash Dasaita A11 image.

this A11-Bild

and then

this A11 Vivid OTA
[MTCD Software Development] ikerg:
if you tried everything (other user reported that the reset button was not well soldered) I suggest as last option a software flash with usbA - usbA.

You need:

A full Android image. (https://disk.yandex.ru/d/umCvHqCDzHccr). Download the IMG labeled one

Rockhip flash tool.

Rockhip Windows drivers (5.1.1 are the latest version)

UsbA to usbA cable.

Stuck On Android Screen | Dasaita

My system is stuck on the Android boot screen. Even when powering off the car and unplugging the battery, the issue is still there. I also tried the RST (Reset) button but it doesn't turn off or reboot into recovery mode. Any solutions?

www.dasaita.com
[MTCD Software Development] h0ckeydude:
Well the reset button does flash after 15 seconds but it doesn't go into recovery.

For the android image file, which one should I use in the link you've provided? I don't see IMG labeled.

Thanks for your help.
[MTCD Software Development] Bettman66:
That depends on the Android version you want. At the top the links from me are for A11.

Hello all,

Just upgraded a PX5 HU from Android 8 to Android 10, I am using HA rom and installed HA3_px5_10.0_ota(20220401) version but I am having some problems with Wifi (not able to connect HU to any wifi network). I also do not much like the design of this A10 version.

Could you please recommend an Android 10 version for my unit?. Is it possible to use any version or should I stick with HA3 versions?.

Thanks in advance
[MTCD Software Development] ikerg:
But does the wifi adapter works?

Take in mind that oldest px5 units came with md725 chip that is not compatible.with android 10.

I recommend you to download the vivid launcher for your unit.

[MTCD Software Development] ostalloh:
Hi. Somewhat new to the whole headunit game. I have an Xtrons PX5 MTCE unit with A10 that I flashed and got Hal9k on it. Decided that wasnt the plan for me so I ended up switching over to A6 but decided I liked A10 better and flashed A10 back onto it using the SD software method. As soon as I did that, the unit updated and after the boot logo it just black screens. Can anyone help/guide me as to what I can do to get it back to the working condition? The image below is what I had it running as and would like to be on that software update if possible. Xtrons isnt being very helpful in responding to my emails therefore I dont think I can receive the factory update and ROM. Thank you and TIA for anyone that can helpView attachment 5794347
[MTCD Software Development] marchnz:
Use OTG to recover. See my thread.
[MTCD Software Development] ostalloh:
already managed to avoid OTG. saved it by pulling A8 firmware and flashing the update afterwards. kind of had to learn on the go but managed to do it on my own. unit back up and running :) only issue I seem to have is that the WiFi slider wont turn WiFi on. it just goes back to grey immediately. any advice on that?

can anyone pls post how a SD card must look like after creating with rochchip create upgrade disk tool?

mine looks like this and can not be read under windows.

is there a limit in sd card? i used 64GB (i do not have smaller ones)

how does my AV8V5 know that it should start from SD? do i have to press a button at startup?

my system was (before i made the error toY choose A11 and installed an A10 rom. now i am in bootloop and cannot get into recovery mode to reinstall)

Android 9

Hal9k Mod v4.4.4

Kernel 4.4.167

MTCE_TONE_V3.40_3

PX6 4.4.2

thx!
[MTCD Software Development] juergo007:
the 64gb card i could not read in windows10 worked

i had to my card into the 2nd slot the MAP slot

press reset once

then i came to bootloader

i used update.zip on slot 1

then i choose reset all factery reset

then i booted automatically in hall9000 android 10

there i updated everything and

i updated to mod 5.0.2

everything seems to work i dont know why.

everytime I make an OTA update 137MB he goes into recovery boot and says reinstall the basefirmware after clicking on reboot now

what does that mean?
[MTCD Software Development] gunnermike:
These files are no longer available. Is there some other place I can download?

[MTCD Software Development] gunnermike:
Answering my own questions here, you have to alter the config.ini file to make it english
[MTCD Software Development] gunnermike:
So I was able to get the tool to work but all I get is a black screen when I insert the SD card to the head unit and reboot.
[MTCD Software Development] angelparras:
Using HAL9K tool i bricked my unit, the recovery did not charge and now i cant acess to any recovery or even the SO.

So i am with a black screen.

I have tried severad micro sd bootable, with android 8,9, 10 and 11 and nothing worked. Even a micro sd with img firmware file, even not working.

Teardown the radio and instead of front micro sd port i used sided one, nothing worked.

I do not know what to do now. I am black screen.
[MTCD Software Development] marchnz:
Otg method
[MTCD Software Development] angelparras:
OTG wasnt working for me.

I tried the HDMI connector and i found that with HDMI i can acess the recovery and the problem was the screen. So i reinstalled the rom and after that my screen worked again.

The screen stopped working after trying to install the recovery for android 8, so after connecting the HDMI, i can install android 8 and after that screen didnt work, but after upgrading to android 10 again worked.

Why? I do not know... I also changed the thermal paste.
[MTCD Software Development] tvladan:
Man, you are a life saver! After endlessly trying OTG maskrom / bootloader, flashing and reflashing I stumbled upon your post.

My situation was

Dasaita max11, trying to downgrade via hal9k mod installer pro 3, to android 10 so that I can install modv5. Ended in black screen and nothig worked afterwords. It seems that all was installed as it should but the HU's display showed nothing. After connecting the HDMI cable to a monitor I could enter recovery, system and so forth ...

Ok brother

Is there any other way to backup?

Like we can backup ROM through twrp recovery in mobiles!

Because I'm afraid. My steering key and reverse back camera should not be a problem.

So is there any way to back it up.
[MTCD Software Development] Clandaries:
There is no working custom recovery to backup the ROM.

You can just install any working firmware for your PX3 but you need the right recovery. For every Android version there is a working recovery. So you have to upgrade the rercovery first or do a firmware upgrade. You can find all answers here in the forum because it is to much to write it here again.

Here are many Firmwares also for your PX3: https://disk.yandex.ru/d/umCvHqCDzHccr

But no. Until now we cant backup our ROM. Just the Apps with data when rooted.

I don't think you could. Check first which bt chipset is selected in your factory settings. Of it is a md725....then you can't go above Android8.

Bt chipsets (bt and wifi) are no longer supported on the most recent Android versions....

It could be possible by replacing some chips inside if ofcourse is detachable from motheroard inside (processor and memory)

Hi all,

I know this is old thread, but I am trying to figure out what is the MCU version in order to decide if I can upgrade to A10 or maybe A11. This is all the info I can get by checking System info. In addition, I don't know the password to enter Factory settings page, in case there is a more info in it, unit is Avin, model: BAVE83A-1025 for 04-10 BMW X3 E83. From communication with the seller, I am under impression that this is PX6 unit because this is the ROM they sent me while ago when I had connectivity issue, which I never used because was related to swapped cables.

[MTCD Software Development] vilooire:
Hello everybody

It has a media car radio, I think it is from the brand ISUDAR, PX3, Android 7.1.2, it is working, with limitations in terms of what the car (Mercedes w203) shows (name of the radio station, open doors, etc.) , but I can also do well with that. With some applications I used (here we go, for example) the question of more modern Android seems to be arising. From what I've been looking for, a lot, I haven't noticed that anyone had put, even just once, the update, on the PX3, from Android 7.1.2 to higher. So I risk saying that I am condemned to keep the device as it was born, without any chance of improvement. Am I right or am I the one who, despite reading what is on the NET about the issue, doesn't understand it?

Thanks in advance for any tips.
[MTCD Software Development] Pavel-71:
Is your device type MTCD/E? If yes, then you got it right. PX3, MTCD/E android 7.1.2, can't upgrade to higher android, the only thing you can do is change the processor board, PX5, or PX6. But the price is high, try to find in the bazaar, moreover, it is not sure that the bluetooth will work, the solution is to replace the module, but you will still have an older device. Better buy a new device preferably with UIS7862 processor 6-8gb ram. The only thing you can try is to install Hal9k android 7.1.2 or Malaysk, you can find everything in this subforum.

Thanks. In fact, my model is an MTCD, so it is in the group of those that will not be able to evolve. Also changing the board, to PX5 or another, is out of the question, and, as is said, it will be close to a new system. Anyway, thanks again for the response to my post.

The MCU say MTCH. I read than the IMG of A11 i can found there : https://disk.yandex.ru/d/umCvHqCDzHccr/RockChip PX6 Android 11

That's is correct ?

Thanks for your answer.

PS : It's possible to update to A13 or 14 ?

If you are not a pro for this stuff do not do it ! Ask your seller of device for help. If you choose to do it yourself most likely it will end in disaster !
[MTCD Software Development] Loteran:
Thanks for your answer, but it's not what I ask. I'm usual whit this on android phones from the beginning of Android, I just want to be sure about which A unit I got and I will do it with otg method like I always do with phones.

But it's better if I'm sure about which img I have to use for update.

And I want update to A11 because I got many problems with some app like waze. It's stop work and clear cash and files not help, I need to do factory reset each time, it s really boring.
[MTCD Software Development] Pavel-71:
Application crashes are caused by webview, previously it was enough to uninstall and disable its updates, unfortunately since the beginning of the year it updates in the background. The only solution is to update the firmware to fix this problem. If you contact the seller and he has no update, you can try M.I.C.#9

Android 11 fixes this, but bluetooth may not work and has other bugs.#155

Regarding your question, you can use an IMG from another vendor and then install any OTA update in the standard way. Mostly the difference is only in the launcher. #1

Someone got an idea for acces it ?

Is no other way for fix web view ?

My seller say he have no update, and without USB acces, i'm scared to try any update, if something wrong i can't fix it.

I will check for make a JIG, but my unit is a screen + autoradio, so i don't know if i can found the SOM like in this post [PX3 & 5] [OTG] - No Headunit Mod, recover or flash a SOM with a simple USB cable - FREE

You can install a fresh new updated copy of Google services and Playstore which are essential for work of device. First, you must disable installed Google services and playstore from APPS menu of device, then download active actual versions from website "https://apkpure.net/" and copy them and install on device thru USB drive. Hopefully , if installed well, other applications will work correctly aswell.

You are probably using old versions of softwares/firmware which is not supported anymore and in need for new updates.

[MTCD Software Development] marchnz:
No, you must use the .img to install Android 10 and then the OTA .zip.

Use the manufacturer supported tools, they're freely available.
[MTCD Software Development] volker64:
Thank your for the quick answer. But the .img it's not a update.zip..only the image. Can I put the .img on the USB Stick, and when I am in the Recovery i started the Update from USB Stick.. Sorry for my bad Englisch and a lot of Questions
[MTCD Software Development] abogrhen:
the problem is the recovery don't accept a change of version, so we need a method to change the recovery

use img file not update.zip

using the 2 method in the top SDcard Method OTG method

or you can use Mod Installer Pro 2(paid)

after you have the version installed you can install ota files like normal

but you can't go back to old one using recovery you need the recovery change method
[MTCD Software Development] volker64:
Thank you. I have bought the Mod Installer Pro 2. So, i put only the .img to my USB Stick, and then the start from the Recovery Modus from the .img...is this right? i don't need a update.zip?

Thank for the help
[MTCD Software Development] abogrhen:
ok

put the img on usb

install the mod app on your device

run the app

chose the version you want

it will wipe data

it will boot to the new recovery you can install the img now

after you are done you can install any ota later
[MTCD Software Development] volker64:
Thank you very much. Later I will install and report

So, I have install the Firmware, but with with the .img on USB they show me alaways a mistake. So, i put the updatezip(ota) on the USB Stick, and all is fine. I install the new Firmware Android 10 with the Mod Installer Pro 2
[MTCD Software Development] abogrhen:
i opened the case and i found the sd slot in the corner

but i couldn't get to from top and from bottom the board is screwed in

only way is to dissemble the unit then cut the metal

but i know i am not good enough to do that :silly:

so i gave up :crying:

_____________________________

I changed my mind

I opened the unit and found the sd reader

Then i removed parts of the casing to allow access to the SD card

I used the sd card method and everything works

Now i install Android 10 hct7 I didn't like hct4 theme

[MTCD Software Development] marchnz:
Might get different response if paying ;)

Just the the full Android 10 .img and then upgrade to an Android 10 ROM of your choice using the OTA .ZIP found in the forums.

You'll find a number popping up as separate/new threads.
[MTCD Software Development] abogrhen:
The only way to upgrade is

Use the one of the 2 methods above

Using the real GPS SD like me

or using USB A to A with laptop
[MTCD Software Development] volker64:
Thats not really correct. I bought the Hal9k modinstaller pro2, made an update.zip (ota) on a USB stick and everything was flashed correctly. I came from Malasyk (Android9) to HTC7 (Android 10) ... everything without cutting the case. I think that's the best solution !!
[MTCD Software Development] Francex10:
So should I use chs img one?
[MTCD Software Development] abogrhen:
yes you can and i mentioned above to you :p

what i meant is there is officially 2 method + unofficially modinstaller pro2

if you have a USB A to A and a laptop you just connect the RockChip Batch Tool and upload the img it works and very easy

or if your unit have 2 SD card slot outside that will be easy too using SDDiskTool to make an update card and use it on GPS slot

the problem if your unit have 1 SD card outside and the second one inside (like me )

and don't have a laptop

you need to use modinstaller or you can modify the case like i did and
