Good morning.

Can i use this method to get Android 9.0?

[MTCD Android Head Units General] marchnz:
Yes but - Not unless someone shares a partition extraction using this method. I haven't upgraded to 9, so perhaps someone else could extract 9 using the OTG method I describe.

I first had the version from the post here a few pages before it and the android I liked much better there

Now I have the update from the first page on it is it possible that this looks exactly the same?
[MTCD Android Head Units General] ikerg:
The problem is that OTA update (the only file type we currently have for android 9) is not suitable for using rockchip tools (software to be used with otg cable)

Perhaps somebody dumped a full android 9 rom and we could build a proper flash file for otg

hello to all, I tried to install the recovery 9.0.5, I have the latest version blue 8.0, my browser is a dasaita px5, I'm trying to follow the video, but I'm bad with the German language and I just did not catch it, the case is I've been doing the same steps that are in the video, and I've put the three files for recovery in a microsd that has my computer as standard, I've gotten them with the file explorer passing them from the USB of the car, but I turned off and on but it does not do anything, it starts normal, I have also punctured in the reset hole and it also starts normal, although the problem has arisen that now the lights of the touch buttons are not lit, and I do not know why, I leave a photo how I have the three files in the microsd, I would appreciate if someone knows why they have been without lights the buttons, I can not find anything in the menus, thank you .. Regards

I think my problem could come because the micro sd is already in the radio slot and I try to put the files through the file manager I do not know if I can do this, I would like not to have to remove the radio from the car, and if what can be the process? That is my doubt, thank you.

[MTCD Android Head Units General] Ujua:
thank you very much better in English, yes, even if it were Spanish it would be perfect jejeje ........., my doubt remains that if I already have a microsd stuck in the dasaita I can pass the three files through a manager files to perform the process or I have to enter the sdcard to start the process, thank you ..
[MTCD Android Head Units General] k3dar7:
Sure NOT, while you use RK sw for write image, then not only normal files is writen, but primary boot part is write to nonvisible 128MB part before first normal partition on microSD...
[MTCD Android Head Units General] Ujua:
what a bad luck !, I thought that copying everything from the pc to a usb and then taking it to the dasaita and pass it from the usb to the sdcard that is set through a file manager with the option of visible hidden files would be enough, if so It is impossible I think I'll wait to take the dasaita on occasion to prove it.
[MTCD Android Head Units General] ikerg:
No entiendo tu pregunta..

1) usa el ejecutable de windows tal cual muestra el video. Seleccionado el boot y con una secar recién formateada en fat32 en tu pc. Si no tienes sdcard slot usa un adaptador usb a microsd en tu pc

2) sustituye el sdcardimage.img creado en tu sdcard por el que viene en el .rar

3) descarga el update.zip (imagen de android9) a un USB flash drive

4) inserta la microsd en tu radio y reinicia:

Ve a ajustes de fábrica y pon la contraseña hctreboot

5) la actualización del recovery será automática y te pedirse que quites la tarjeta.

6) aparecerá el recovery nuevo en pantalla.

7) elige actualizar sistema por USB introduciendo tu USB drive con el update.zip en ella

Voila

I was looking into the sdcardimage.img file included by halk9 and it is a perfect image to be used by the otg cable by means of using any of rockchip upgrade applications...

Use it normally as fw file and upload your system by otg cable...then reboot and you will find the new recovery...use it to upgrade to android 9 by means of using the ota update provided

Hello Everyone,

Can i use this "PX5 HA_px5_9.0_ota(20190415)" Version for my HA5225 Unit?

I have this Unit: https://de.aliexpress.com/item/3285...ail-2014&spm=a2g0s.9042311.0.0.110e4c4dTYIpZW
[MTCD Android Head Units General] ikerg:
User must know which unit has...

If you have a px5 unit from dasaita...then you can:

* if you are on android 9 already...the update is direct update

* if you are on android 8....you must update recovery first and then upgrade..

Android 8 and android 9 recovery and partitions are different.

Hi, how would I have to update the recovery to 9.0.5 with OTG cable? Can someone confirm if I can do it? What would be the procedure? Is it to put the cable with the USB with the files created on the pc and restart from the reset hole or do we have to do something else? ..

thanks

[MTCD Android Head Units General] ikerg:
I answered you before..

If you have sdcard slot....USE IT.

You have to prepare the sdcard for recovery upgrade ON A PC and use the prepared sdcard onto your headunit.

If you go to otg cable (need a USB cable ...resistors and soldering)... first you have to build your own otg cable

Extract your headunit fromm the car and remove the coreboard... plug the otg cable to coreboard and to PC...upgrade the recovery...and put all back again.

Are you sure that you prefer the otg cable.method?

Did you check the thread I posted two posts earlier?

All the information is there.

Hi Everyone,

I have an HA2157-V840-8 that I have updated before using the px5 update images for Android 8.

I now have a non-working unit after trying to upgrade to Android Pie.

I followed the instructions found earlier in the thread but after updating the Recovery and then applying the Androir 9 image from the first page the unit did not boot.

Tried again and had to re-flash the recovery to be able to get in to recovery and now it won't apply the update as it reports that the package is for a 'px5' device and that this unit is a 'rk3368'.

[MTCD Android Head Units General] ikerg:
This thread is for dasaita updates....

Dasaita never supplied a android 8 to android 9 upgrade method and never will.

Upgrading from 8 to 9 is not a direct method...and there is some risk (low) on bricking your unit.

There is a thread of android 9 for px5 to support for all questions of upgrading and functionality...and it is posted by me a few posts earlier.

There is a complete information about the upgrade

Android 9 does not have any to do with your sound...all mtcd units hace same audio chips that are controlled by mcu

Did you update anything else like mcu?

Try to reboot the system... go to factory settings and in password type hctreboot

If not...Now that you have the android 9 recovery installed try to upgrade again your system but using only the recovery or the system upgrade from settings.

Which android 9 rom did you use for the update?

If you wan't to update from Android 8 to 9, can you do it without removing the radio from the car eg. using a USB stick or download/copy the recovery files to the "GPS" SD-Card.

I don't want to remove the radio and that's necessary, if I need to access the SD-Slot.

I thank you, but do I have to install it like this? Do I need to edit image?
[MTCD Android Head Units General] k3dar7:
if your device not have special connected USB (and sure not, if have SD-Slot), then using USB is not posible to recovery upgrade...

simple copy "recovery files" to already inserted SD-Card is NOT posible, because RK tool need for creating SD-upgrade-card NOT only copy files to visible partition, but also repartition whole card, make start of first/one partition to 128MB from "card start" and before this partition write "bootloader", to make sd-bootable without using this tool is posible if you grab on pc from already created sd-rk-bootable card first 128MB, but without root is i think not posible repartition inserted card and write this image using dd to card...
[MTCD Android Head Units General] ikerg:
You dont have to edit anything.

Just create the boot sdcard as usual...and replace the sdcardimage.img with the one corresponding to the recovery for android 8

Edit: anyway is NEED prepare UsbFlash with RK writing tool, this create boot part before moved partition, if SW not show you usbflash as target, then maybe raw targed frommicroad to usbflash (using dd in Linux, or some raw image backup/restore tool in windows)

simple try create bootable USBFlash in RK tool (SD_Firmware_Tool.exe), i try run and see me inserted USBFlash (don't try write, because have data on flash :)

whole process be same as with microSDcard, from this grab Hal9k_Mod_3.x_upgrade_to_Android_9.0.rar

and follow howto part "If you have Android 6 installed" on first post in Hal9 thread (but ofcourse use files from Link: Hal9k_Mod_3.x_upgrade_to_Android_9.0.rar and USBFlash instead of sd card)...

If HU not boot from one USB port, try another USB port... always need full reset via reset hole or hold power button until leds blinks... if none of USB port not boot, then you're out of luck ;)

btw: i not tested this, i have HU with gps slot in front, although i think using this USB is save and in worst case simple not boot from USB but normal system from internal... all steps is only on your responsibility ;)
