there are some bugs

for example if you set "shut down acc off" to AUTO after a few days the screen will remain black(you have sound but no screen) and you have to hard reboot the device

another thing is VPN , if you enable VPN from the settings you will be forced to set a lock screen,and if you set lockscreen after each reboot the device factory resets itself

Hey, I have the June 12 MX rom installed. I have the problem that some of the system settings aren't saved. Everytime i restart the car settings are gone, even though iam in the quick boot mode, which I thought meant the radio would always be in some sort of standby mode.

Settings are for example: I installed nova launcher and the settings from nova to use some of the buttons is not saved.

Any one with similar problems?

Thx

I used Hal9k's installer to install Android 9 successfully. Now the issue is, after updating to the latest dmcu for HA (3.30), the boot after reset loads the upgrade card screen and pulls this image next: https://xdaforums.com/showpost.php?p=80077830&postcount=2515

Now this only happens whenever I have the sdcard I used to set this up. I reformatted the sd card but still am reproducing this issue. Anyone have any insight as to why this is happening? Or should I just install another sd card?
[MTCD Android Head Units General] proto__:
So the Memory card still has a bootable partition? And it works fine with the memory card out? You can re-format the card in that case.

Take into account that the bootloop occurs if you try to downgrade to a lower date of android 9 rom.

Additionally your seicane is not HA (Dasaita) and you upgraded your mcu with dasaita mcu file....that's why your red mesage of mismatch

if you after need revert back, then in Windows (GUI) is i think not possible, maybe using diskpart(in command prompt), in GNU/Linux ofcourse possible using simple step with delete/recreate or move start of first partition using Gparted(GUI) or parted/fdisk/cfdisk/etc.... anyway you can do it in Windows again using "Rockchip Disk Tool" and click to "Restore" button ;)

Hi,

I am trying to upgrade my MTCD PX5 (MX) to Android 9. It was originally Android 8 and I was running it fine for the past year (e.g. I had updated it). I have also updated to MCU v3.13.

I get the following message when I try to apply the system update:

I believe this is getting generated from the updater-script:

getprop("ro.product.device") == "rk3368" || abort("E3004: This package is for "rk3368" devices; this is a "" + getprop("ro.product.device") + "".");

But that's as far as I've gotten! I thought PX5 was rk3368... ?

So I guess it's trying to read the Android 9 installer update.zip and failing.

I am trying to install hct4_PX5_9.0_ota 20190813.

Does anyone know how I can continue?

Thanks!

Edit: I'm seeing the above message at the 3:25min mark of this video: https://www.youtube.com/watch?reload=9&v=EhEdeD5RICk - I have installed the bootloader.
[MTCD Android Head Units General] k3dar7:
read first post with info about upgrade recovery first...
[MTCD Android Head Units General] proto__:
Ahh, thank you - these are all related!

Silly me, I must have been using the same memory card from when I upgraded Android 8 last year. The Rockdisk tool didn't overwrite the existing 128mb boot image partition on the card with the Android 9 boot image!

The fix = use a fresh memory card or follow the below process...

In Windows 10 disk management tool, I could see the 128mb 'unallocated' space. I deleted the existing partion on the card and created a new FAT32 that used all the space (quick format fine). This resulted in only one partiion and no unallocated space being shown. I then used the Rockdisk tool again and this time the Android 9 bootimage was setup. From there, I now have Android 9 on my HU.

I should have listened to my own advice! But as it was k3dar7 helped us all. Cheers.

The rom is for all mtcd/mtce px5 devices independently of the manufacturer.

The mcu upgrade is only for the specific manufacturer.

If mcu 3.30 is LM as well you can install

Mcu upgrades usually includes enhancements on the canbus or new canbus supports.

Seicane H221 Android 9 developers options, recovery

It seems Seicane hid the developer's options in Android 9. I tried to contact them and after 10+ emails they finally told me that it's blocked and I can't access it. I also asked them about going into recovery and they just said abd. I haven't tried adb yet, but will in the next few days. I saw a px5 rom on xda but don't know if I dare as I don't have a stock rom to reflash if I soft brick. I know you don't need developers options or custom recovery for flashing a rom, but I've bricked a few Androids in my day and don't dare mess with this HU without a net. Any ideas about getting at least developers options? Thanks Johnm

In Android 9 it seems there is now the ability to hide developers options. There are directions to do this, but no directions to get unhidden. With developer's options you can speed up different aspects of the interface, enable usb debugging, many, many things that might ultimately help you get root, which we all know is a major advantage

If your HU has a DSP it will have a 15 band equalizer and delay control by the speaker distance and they will work. If you're having bad FM reception find a schematic for the car entertainment system and confirm if it has power going to the antenna. If the antenna needs power you will need an antenna adapter with a power injector.
