Hi everyone, I'm kinda new here so this topic might have been up but couldn't find on a search. I have a Android head unit px6 MCU rk3399 rockchip for a 2012 Sierra Denali and it has no buttons other than a small reset hole that only restarts the unit. I was able to root it runs Android 9 but I can't get viper4android or any type dolby installed because when updating the su binary it bricks the unit. Also cannot get to bootloader. It's like it doesn't have one. Tried reiboot for Android and can get it to recovery but that's it. I was curious if anyone has been able to figure this thing out. Like installing a custom recovery, TWRP... Any advice would help. Also I was wondering if it is possible to create a bootable Android flash drive for Android 9? Thanks in advance and if I'm out of line asking or if I'm in the wrong place asking this you could tell me to f-off and I'll understand

I have a MTCD Jeep specific Joying HU. The touchscreen is starting to fail and I need to send it in for warranty. I currently am using Malaysk rom and need to go back to stock before I send it in. Does anyone know where I can get a copy of the stock rom?
Have you checked the joying website? Appears they have update files in blogs and the forums.
Yeah-nah?

I found a page on their website that was for an upgrade. It also said on the page, " Note: Please do NOT upgrade ROM from Malaysk on forum.xda-developers.com or other brand. Because it is a serious issue, it will broken head unit and dead(WIFI doesn't work, head unit die). If you updated you do NOT update your lollipop anymore and will lost warranty. See this video https://youtu.be/pGCROGRV1Mo , it is NOT really android 5.1.1 lollipop verion."
So I am not sure if I should use it. I down loaded the zipfile and it contained 2 files, duplicate.img and dmcu.img. Duplicate.img is the same name as on the Malaysk's. I haven't seen the dmcu.img before.
Any thoughts?
Is there somewhere a website where i can download stock roms or almost stock roms for my head unit?
I upgraded my system from PX3 to PX5 some months a go by purchasing a PX5 som board from witson.
My SOM board is from the seller witson and has MCU:
MTCD_HLA_V2.52_1
Currently my PX5 head unit (rk 3386) is runing latest Malayks rom.
I want to set the unit back to stock rom but do want root access and xposed installed, a factory reset will not set back the original rom, sadly i do not have a backup of the rom.
I only have the original rom from my PX3 som board, don't believe i can use this ROM on my PX5 board.
Also i am looking for newest MCU, my seller reports they do not have this unit anymore and the new unit is currently on android 7, the last MCU they had was 2.52 and they have no newer ones,
The manuafactor is Hualingan (= HLA), maybe someone as a newer MCU which i can download?
Hello
I have a px30 android navi with mtce "software" it is Android 8.1
i found now on the https://yadi.sk/d/umCvHqCDzHccr page the folder RockChip PX30 Android 9.0
Is it posibill to update my radio with this file?
If not..is there a other update to android 9?
if i am not happy...is there a solution to make a nandroid backup from my Radio in the status from now?
Thanks for help
If your headunit is a PX30, then maybe.
Your "dcmu" under settings should look something like this i guess: MTCE_??_?.?? (mine for example is MTCE_MX_3.06) In your case it should state GS
As of my current knowledge, there is no root for 8.1 devices yet, just 8.0 and below (with the custom roms from hal9k or malaysk).

Hi,
Did you manage to upgrade to Android 9.0? I have tried several times but have been unable to do it. Always end up getting an error message.
Cheers.
No.. I wase to scary to brick my device
Hi, I installed the mcu files by mistake and now the device is bricked and does not come up. It only gets stuck on the boot image. What is the solution? (How should the recovery file be injected into it?
Px5 unit head
I have tried many times with the reset button and it does not enter the recovery mode
If you have an MCU MTCD/E:
Instructions for entering the recovery are in the video:
If you can't get into recovery, try PX5 stuck in bootloop:
PX5 stuck in bootloop
This Post details how OTG/LOADER can be achieved to recover a corrupt PX5 or PX3 - any RockChip MTCx SOM Update 2/2018 - anyone can make a gig without modifying their main board. BUT FIRST try a USB port, some have OTG out of the box. From...
forum.xda-developers.com
The last option is to buy a processor board, the functionality of bluetooth and wifi is not guaranteed:

Is the device MTCD? Post MCU version.
Thank you all, friends of the device, it was fixed. But I just wanted to install the official Android 10 ROM via microsd, which unfortunately I still can't install. My mcu version is kld and I flashed the chs via sddisktool because the Android 10 version for kld has not been released. !!
Is there an installation solution via microsd?

But when I connect the microsd to the device, nothing happens.
Hello,
about two years ago I purchased myself a nice head unit for my BMW (PX5) and it has been working nice since then, but it's on Android 9 and Google Maps won't update on my unit anymore, even though the maps themselves are being updated no problem. I fear that there will be no more updates for my apps if I won't do something about it and replacing the head unit is out of the question. I'd like to know how to upgrade my unit to newer Android version and if it's even possible. Disclaimer - I've never done that before so I'd like to do it as safely as possible so I won't accidentaly brick it because of a wrong software or something
The specs listed in the device are as follows:
Android version: 9
Compilation number: rk3358-userdebug 9 PQ2A. 190305.002 20190612.101357 test-keys
Kernel version: 4.4.167
MCU version: MTCE_CHS_V3.02_1
Also, there are MCU update and device update buttons in the settings, but the device won't do anything when I press the device update button and MCU update one tells me that there is no MCU file. What is this?
