after a whole day trying to get the sound working again it' still not working.

i did learn more and more about the system whithout rusults. i found out the the unit dous have a micro sd connection only its not connected. whith the old board i managed to get it back to recovery 8.0.5 only i get the error 21 with loading android 8.0. there for i read that it can be solved with a sd slot. meaby i can get it to work when i buy a 12p plat cable. if i want to load android recovery 9.0 with the otg cable i get an error.

But i really want to get the sound back to work with the other board. i have tryed to update the mcu 3.01 but still no sound. The amplifier is still "blue" and i had a more orange layout.

I found this mod:

https://xdaforums.com/android-auto/mtcd-software-development/mod-bd375xx-sound-processor-t3834657

that layout is the same what i had, updated it but it still no sound

somehow i think that the dsp is seprarated from the mcu update. so i need a other update only for the sound processor? the wierd thing is i can hear the beep when touching the screen. but when i select a cource i only hear some creaking out of the speakers
[MTCD Android Head Units General] ikerg:
Did you go back to xrc mcu as I provided?

You did some mods on your side...

First...you changed from xrc to ha (even could work your motherboard is made by xrc...and the mcu controls all the motherboard.

The sound chip is there too.

1)Update your mcu to xrc again.

Check sound

2)check factory settings...and check which canbus settings do you have.

In amplified cars.. external amplification is controlled by the can bus...if during upgrade you lost your settings...and you have the canbus settings wrongly configured....the sound will not be passed through amplification and you will no hear anything

Which car do you have?

Do you have canbus?

Which canbus do you have?

Which canbus is configure on factory settings?

Which android rom.are you trying to install?

If you loaded android 8 stock recovery you can't upload custom android 8 rom...just stock android8 rom....(malaysk and hal9k custom roms have their own recovery)

That could be the verification signature error.

When upgrading .... ensure no other USB ports are being connected

[MTCD Android Head Units General] rocar:
thank you for your advice!

I did not do any mods it all started after updating the board with the otg cable.

before i started i took pictures from al the settings by factory settings, at that point everything was working. now i used the same settings.

i have a polo from 2012 and it has canbus. It has no external amplifier.

I have next to the radio a seprated canbus controller, this one i disconnected. Two other wires i have to connect to get power but still no sound.

i have read in a tread that the same mcu firmware is used for a radio with and without DSP. So is there some were a way to tell the radio it has DSP?

Below questions I've in relation to Dasaita PX5 Android 8 unit.

1. Does the split screen works with Android 9?

2. Is there a changelog for Android 9 so we know what's actually different/better from Android 8?

3. Is there anyway to get/port the skin or launcher from the Dasaita BMW unit to a dasaita PX5 for Qashqai? (I know this is a weird question but am just a sucker for that BMW launcher [emoji3]).

Just want to be sure it's worth it to update especially since I've to take out the HU to get to the SD card slot.
[MTCD Android Head Units General] ikerg:
BMW dasaita units hace specific laucher adapted to specific resolution.

I dont think it could work.

Android 9 has split screen but not working on last px5 rom...it is working in the most recent px6 android 9 rom (as well as GPS clock fix) ... so we need to wait for the next px5 update in which probably it will be solved

Did you revert back to xrc mcu?

You never answered about that.

Hi

Just to make sure - if my Dasaita PX5 came with android 8 it is not recommended to upgrade to android 9 even tho the update is available in this post.

Thanks in advance.

Hola buenas, soy nuevo en esto y tengo un problema a ver quien me puede ayudar. Tengo una radio 2DIN para una Peugeot Partner y creo que es una PX5 version android 8.0.0 Version Kernel 4.4.103 y ha dejado de funcionar ya que no enciende. Necesito saber si es posible ponerle un nuevo sistema y cual es, gracias.
[MTCD Android Head Units General] rocar:
i got it working again!!!!

yes i tryed diffrent mcu's also the one you said to try. non of them was the solution.

what i did:

- with the android tool v2.35 i first erase the flash

- then i loaded the bootloader v2.6 on the board

- connected the board in the radio and waited when the radio comes in recovery

- disconnect the board again, and with the android tool loaded sdupdate 7.1!!!

- again reconnected the board in the radio and waited to see earasing in the screen appear, afther that waited 30 sec.

- again disconnected the board and loaded sd update 8.0.

- for the last time reconnected the board and this time get in recovery with recet button and power button.

- in recovery selected "apply update system and installed android 8.0

now the sound is back with the dsp amplifier. The key was to do first a 7.1 sd-update an then the 8.0 sd-update. if i leave the 7.1 update out of it the sound was not working!

thanks for your effort to solve the problem!!!!!

First....this is an English forum...

If your headunit does not switch on....why do you think you can change something in the android system?

First you need to figure out how to make your unit to switch on....if your problem is that android does not boot then you can do something but...

You need first which unit you have....here only is supported px5 units based on mtce mcu type.

If you have px5 based on other type of mcu....this thread is not for you

[MTCD Android Head Units General] marchnz:
Have you tried turning it off and on?
[MTCD Android Head Units General] w.wallace79:
Yes, I tried to hit the "reset" button and nothing. The radio is blocked on the home screen with the logo without getting started.
[MTCD Android Head Units General] tebukan:
Remove the battery plus pole end of the car, wait for 15 minutes, then reinsert it and start the car. Try this one too.
[MTCD Android Head Units General] ikerg:
Is very different not working at all than being stuck at boot logo...

In that case..

First we need to know if your unit is really a px5 mtcd/mtce...tell us which brand of headunit is....or the link where you purchased from

If resulting in mtcd/mtce then you can download the last rom for android 8 and upgrade your unit from recovery

But first is first ...we need to know the unit type to avoid bricking forever your unit.

[MTCD Android Head Units General] w.wallace79:
The radio if it turns on but does not start with the system remains blocked in the home logo nothing more. Next I put the purchase link because I do not know if it is mtcd / mtce.

I tried to install the recovery 9.0.5 as shown in this https://youtu.be/EhEdeD5RICk but the issue am having is that when the HU is restarted, the recovery is not installed. And when i tried to do the installation directly from the Android recovery Menü, i get the error in the pic below. Any idea how to get this to work?
[MTCD Android Head Units General] k3dar7:
inserted card in gps slot?
[MTCD Android Head Units General] naira1:
Yes, 8gb card. Is the recovery 9.0.5 supposed to be installed as soon as the Hu is turned on?
[MTCD Android Head Units General] k3dar7:
If card is prepared ok and inserted in gps slot (slot with boot support), then after reset HU is booted from this card and run repartition/format/upgrade_recovery, after this remove card, reboot to installed recovery 9 and install A9 update.zip
[MTCD Android Head Units General] naira1:
So the issue was with the size of the card. I used a 4gb and it's installed now.
[MTCD Android Head Units General] Doctor1234:
So 4GB is the max size you can use in the GPS card to be able and upgrade the recovery to 9.0?
[MTCD Android Head Units General] naira1:
In my case yes. I took the exact same steps with both cards and the 4 GB card was able to install the recovery as soon as i put on the HU. I Know for fact that the 8 GB card is fine because even with Android 8, it was recognise in normal mode. Just not installing the recovery.
[MTCD Android Head Units General] Doctor1234:
Ok coo, thanks for this info, I have the same issue with my 8GB card, I will try with a 4GB card.
[MTCD Android Head Units General] k3dar7:
With Dasaita HA2021-V600 4/32GB i use 16GB Samsung(orange) microSD, then i think depend on HU model or card model/vendor. Anyway good your success :)

When in the firmware name it says OTA ( PX5 HA_px5_9.0_ota), should it not be possible to update over the air?

I just updated to Android 9 but with the firmware from April, now i see a new firmware from May and doing a new installation would wipe my data and apps. Not the ideal solution for me.[emoji2]
[MTCD Android Head Units General] segu45:
If you have the April version, normally only with putting this new one on a card, the system will detect it and you can update it if you want. Say yes without wipes and you will not lose anything. you only have to make wipes when you change ROM or version.

[MTCD Android Head Units General] k3dar7:
i think OTA in name is only mistake ;) anyway you have installed now Dasaita version? HA_PX5_9.0_ota(20190415) ? i think update to 20150521 NOT wipe data, wiping was need only if make upgrade to new Android major version, because is need repartition whole flash for different partitions need, but if i before year make upgrade from 6 to 8, then next all 8 updates i make without wipe, not use rk boot sd, only put update.zip (from PX5 HA_X.0.ota-date.. archive) on normal formated microSD card and in Settings/System click to Update System...

but if you wait 30m then i doing update from april to may on me HU and report if data keep ;)

Thanks for testing this. You are the 2nd person i know who said the data was wiped after updating from the April to May version.

Am not sure if i want to go through the hassle of sitting in the car for so long setting stuffs up afterwards.

So any known improvement of the May version over the April one (apart from security patch)?

What i can say though is that my DAB+ is getting a much better signal than with Android 8. So that's good.

in May update is SecurityPatch April~04, i don't remember wha is in April update, but i think in Android8 is SecurityPatch not updated with update.zip but keep/same year(?) old??

i noticed meantime in May that Time is not broken, if i after one hour go to car and power on HU, then time is actual, i don't know if run in background or if is simple set via GPS, but in April i must always go to settings time and off/on gps time...

Split screen out-of-box not found, maybe is some settings in developer settings, but in A9 is not possible enable via click to build, i try some other way enable via adb (not work, for older android), editing developer.xml(not found file in /data/...), but sure try find working way tomorow...

Howto ROOT PX5(or maybe all arm64) HU with Android9

All used files is from "HvdWolf" projekt "Joying-RootAssistant":

1. Install "Joying Extra Tools" apk to HU, run and click "Enable adb over Wifi"

2. Download SuperSU-PX5-ARM.zip to PC and unpack

3. in unpacked dir change in file copy_install.sh (on GNU/Linux) or copy_install.bat (on Windows):

adb shell mount -o rw,remount [B]/system[/B]

to

[B]adb shell ln -s /dev/block/by-name/system /dev/root[/B]
adb shell mount -o rw,remount [B]/[/B]

4. follow authors howto, section "Steps on the Rockchip PX5-A53 ARM units"

(is ofcourse need having HU and PC/NB connected to same Wifi network)

4b. if running copy_install.sh script part remount as rw is not success and say "'/dev/root' is read-only" followed by many "Read only filesystem" errors (as for me with new PX5-20190528),

is need disable DM_Verity using:

# disable DM-Verity checking
adb disable-verity
# reboot device
adb reboot

5. reboot HU and run SuperSu app, is show "SU binary needs to be updated", ignore this because Normal(/direct) update not work, and update via TWRP/CWM need ofcourse installed TWRP or CWM recovery :)

anyway, after skip this update, SuperSu normal working...

6. Don't remember "Disable adb over Wifi" in "Joying Extra Tools", because enabled/disabled state is remembered also after reboot ;) (and without user accounting is possible anyone on same network connect to your HU)

7. For readwrite access to rootfs always run before:

# from PC
adb shell ln -s /dev/block/by-name/system /dev/root
adb shell mount -o rw,remount /

# or from already connected "adb shell" or via terminal direct on device:
ln -s /dev/block/by-name/system /dev/root
mount -o rw,remount /

BTW: i compared su and Superuser.apk in "SuperSU-PX5-ARM.zip" archive with official/latest(?) SR5-SuperSU-v2.82-SR5-20171001224502.zip and is 1:1 binary same...

EDIT1: add item 6.

EDIT2: add item 4b

EDIT3: add item 7

PX 5 - Android 8 -> 9 ... semi-successfull upgrade ...

Hello,

I upgraded my PX5 unit from android 8 -> 9, changed the recovery as described and directly installed HA_px5_9.0_ota(20150528) ... everything worked as expected BUT when the system powered up I realised some 'flickering' which didn't disappear.

Finally I booted into the 9.0.5 recovery and the same flickering (white horizontal lines ... 2-3 cm ... occur out of the sudden, disappear ... return somewhere else) was present ... after I returned to 8.x recovery (no flickering anymore inside the recovery then) and installed some suitable rom the flickering was gone ...

I noticed, that the resolution was fine and the font-size seemed 'normal' to me ... no stretching/messed up display-settings etc.

Current MCU: 3.06_1
