[MTCD/E] Android 10 upgrade using official Free tools

[marchnz]

To upgrade a MTCD/E PX3, PX5, PX6 from Android 6+ on using official Rockchip free tools - a reminder, bringing together multiple threads.

First note - if coming from Android 6 - early versions of Realtek dual BT/WIFI (type 2) are not supported past Android 6.
[29/06/2020 - Android 10 - Users are report Bluetooth MD725 Type 1 is not working on Android 10...]

The only fix is to replace the wifi/bt module with the supported "type 1" GOC-MD-725. See this thread for details (placeholder)


Risk:
Also, there is risk associated in upgrading. The SDCard method is known to result in back-screen, sometimes recoverable booting to recovery from SDcard again. If this method fails, OTG becomes the only recovery option.

Two Rockchip Official methods;

A. SDcard Method
Note: To use these methods, your unit must support booting from SDCard or USB. Not all MTC variants are created the same, so test first.


The following is required for SDcard method
- (1) Full ROM in .IMG format
OR
- (1b) bootloader/recovery only image to flash recovery,
https://drive.google.com/folderview?id=11zpgoOW4eU6G1tjs7ExsZ2aC4RoZ9KDr
AND
- a 'full' OTA of your choice.
- Rockchip SDCard create tool
https://github.com/rockchip-linux/tools

1. Create SDCard using Rockchip SDcard create tool.

2. Insert and boot from SDcard, follow prompts.
3. Wait for install to complete...and can take some time

(1b) Flash boot/recovery image then an OTA zip. Thanks to @ikerg for recovery .IMG files.
2b. Create SDCard using Rockchip SDcard create tool with .img

3b. Insert and boot from SDcard, follow prompts.

4b. After flashing, remove SDCard, boot to recovery then flash an OTA from another SDCard or USB stick.

* Download bootloader/recovery flash image from here; https://drive.google.com/folderview?id=11zpgoOW4eU6G1tjs7ExsZ2aC4RoZ9KDr



B. OTG method - "Never fail, flash like a Boss, impress your friends method"
*May require Jig, or if lucky an USB A-A cable.)
The below method will recover a 'bricked' or non-booting unit.
If wanting to backup your ROM and test other ROMs, this is the method you want.

The following is required:
- ROM in .img format, or partiton extract
- Android Tool and Driver:
https://github.com/rockchip-linux/tools

1. Install Rockchip driver and Android Tool on PC/Laptop.

2. First try connecting your unit USB to USB using cable to PC. Try all headunit USB ports.

3. Try entering recovery. If successful you will hear the new device chime on your PC and the headunit will be connected.
If connecting via USB method does not work, a jig must be made. See the following thread for details: https://forum.xda-developers.com/an...px3-5-headunit-mod-recover-flash-som-t3766892

4. Using Android Tool connected via USB - Flash SOM using .img file. If image file does not install, erase flash first after selecting .img file.


C. Downgrading steps here: https://forum.xda-developers.com/t/...ing-official-free-tools.4123933/post-85473141

Hope this thread clarifies the two free and official methods to upgrade your headunit. Enjoy.

29/06/2020 - Update - Users reporting MD725 - Type 1 Bluetooth is not working on Android 10.
28/07/2020 - Update - include bootloader/recovery plus OTA method from IMG files kindly created by the talented @ikerg .

29/06/2020 - Update - Users reporting MD725 - Type 1 Bluetooth is not working on Android 10.

March 2021 - Update - BT module found - HW upgrade to enable Android 10 upgrades. See my module thread.

August 2021 - SD Card Downgrade steps - from A10, A9 using A8 for success.

Note: Best, most successful risk free method - OTG

In the other rom thread people reported black screens when trying to upgrade. I had the same issue. I used 2 SD Cards to successfully upgrade from Android 8 to 10.


With card 1: I created a SDCard using Rockchip SDcard create tool with the following ROM https://yadi.sk/d/umCvHqCDzHccr/RockChip PX5 Android 10/CHS .

With card 2: I followed the instructions from [https://forum.xda-developers.com/showpost.php?p=79513558&postcount=2] section a) until point 10 / the video https://www.youtube.com/watch?reload=9&v=EhEdeD5RICk until 2:55. I then put SD Card 1 into the HU and pressed reboot in recovery. I then saw the Android 10 update screen. It took about 30 minutes to update, it then booted into Android 10.

The rom seems buggy. I'm not sure if its the upgrade method or the rom itself. I'l try to flash a different android 10 rom to see if it works any better. Worst case I can flash to Android 9 using card 1 / Malaysk ROM.

Hope this makes sense.

I already posted which ROM I used. Not sure if it's special or you can use any Android 10 IMG file.

I have MD725 BT module, i think is type 1, never had problem with bluetooth before, from android 6, 8 and 9, and now with A10 is broken. Tried 3 different rom. So replace with what? I will downgrade to A9.

There will be no way to get this module to run on Android 10. The best thing would be to replace the module.

 

[zeyret]

A10 recognizes the MD725 module as BC6 but does not establish a connection.

 

[alt.d4c]

I will try all the options listed in factory settings.

 

[Clandaries]

I installed A10 with the Boot-SD method, like i did with A6 and so on.

But it did not work like it has to. You have to manually go to the recovery. Inser the SD-card and then press reboot to sytem.

After that the install begun.

Now i am looking for a way to root A10.

Regards

A10 recognizes the MD725 module as BC6 but does not establish a connection.

How was that identified? Do you mean if you set the module in factory settings to bc6? Or is that the output of a logcat/dmesg?

Could someone with a md725 type1 kindly export and attach dmesg and logcat from their android 10 upgrade?

I can then take a look and try to figure out what's going on. Really wish I had a second unit to mess around on, so I can try and figure out potential mods etc to fix this md725 problem.

I figured out the hardware mod to get working md725 on Android 6 on...but haven't had anyone willing to donate hardware (need a headunit, even without a SOM)

Hello thank you for this thread.

Just to be clear, flashing from sdcard an OTA file from android9 to android10 (without hal9k modinstaller) will result bootloop because recovery and bootloader are different ? am I right ? (I always did it with modinstaller)

Also what I did not know is flashing .IMG file will change bootloader and recovery with sdcard tool ?

You need the img file not the OTA

Android 10 Bluetooth MD725

Hi @marchnz
Bluetooth MD725 and WQ_BC6 logcat / dmesg

I have Dasaita MAX6. I am trying to do SD Card upgrade method. With both 16GB SD and 4GB SD card, when I reboot from recovery, I just get black screen. Has anyone with Max6 gotten this to work? If so, what exactly were the steps followed and files used? I am trying to use this IMG: https://docviewer.yandex.ru/view/0/...wODEyNDcsInl1IjoiOTQ0OTU5NzE3MTU5MzUyOTkyOCJ9

Use 8GB or less SD card.

 

[graycorgi]

Use 8GB or less SD card.

I did, I tried using a 4GB as stated. I did get it to work though. Used a different computer with a different SD card reader.

Hi @marchnz
Bluetooth MD725 and WQ_BC6 logcat / dmesg

Hi, could you check the files - looks like these are all the same 1 kilobyte file - a MCU Configuration export - and not the actual logs

 

[Clandaries]

In my case, i have a 10,1 inch MAX6

This one has a GPS card slot behind the screen but in my case this is a fake GPS card slot.

But i knew there is a sd-card slot at the side of the head unit hidden behind the sheet metal.

So i opened the head unit.

Then you have to make a boot sd-card, manually boot to recovery, insert the sd-card and then boot to system and the system update starts.

 

[abogrhen]

so i have a question

there is img and ota files for PX6 on HCT folder

i will need the img file to do this

but can i use the ota afterward ?
and is HCT7 and HCT4 the same ?
