ok i got sd card to write using a usb sd card reader. i followed these steps to make sd card.

Download and unpack the archive Hal9k_Mod_3.x_upgrade_to_Android_9.0.rar

Insert the SD card into the card reader. It is desirable to use a small card, 2-4-8 GB.

Run Rockchip SD_Firmware_Tool.exe on a convenient Windows PC with a Micro SD card reader/writer connected to it. You must run the application as Administrator.

You do not need to switch any settings. Everything is set up.

Click the "Firmware" button and select the file bootcard.img

Click the "Create" button, then "Yes" and wait until the message with the "Ok" button appears.

Close SD_Firmware_Tool.

Copy the sdupdate.img file to this card, replacing the existing one.

Remove the SD card from the card reader and insert into the HU in the GPS slot.

Now you need to completely reboot the HU. This can be done by pressing the RST (Reset) button with a paperclip etc.

If the HU does not reboot, then this button (or the Power button) must be held down until the buttons backlight flashes. Then release.

As a last resort, you can disconnect and reconnect the power cable.

When the message "Doing actions succeeded. Please remove the sdcard ..." appears, remove the SD card from the HU.

i put the sd card in radio and it just stays on hal upgrade card. i never get the message Doing actions succeeded. Please remove the sdcard

[MENTION=5092263]Hal9k_[/MENTION]: I would like to try the new firmware. But before that I have some questions:

1. Which issues do I have to expect after flashing it...what do you think?

2. Is it correct that I we have to replace update.img (created by SD_Firmware_Tool) by update.zip from Y Series_PX5_9.0_ota(20190322)? I'm asking because I'm not used to flashing zip's instead of img's.

3. Can I flash the firmware using a usb stick? I don't have any small sd cards.

4. Is the new firmware optimized in some way to PX5 devices and should work properly or it is just adapted from an existing update for any android HU?

Thanks in advance...
[MTCD Software Development] Hal9k_:
Search in the thread.

This is intended for px5.

This may take a long time on some HUs.
[MTCD Software Development] Hal9k_:
1. Any. This is a new version of Android. Although I did not notice any obvious problems.

2. In the first post there is a link to the video.

3. No

4. This is stock Android for PX5.

How do i initiate the "Check for updates" for the OTA update?

I had the popup for an update from 3.1.1 to the newer update but as i was turning off my car, i didnt update.

Today i want to update, but after putting on my WIFI im not getting the popup yet.

I went into the "System Update" area of the mod9k app, and it is checked "Automatically check for updates" but i still havnt had a prompt or popup yet.

i have a mtce-xrc running mcu 2.94. would like to know what we are doing wrong too. Thanks TW
[MTCD Software Development] Trayal:
Thanks for this.

I just wanted to confirm, for all those searching for a solution, that this is the needed action to allow permanent installation of older versions of ViPER4Android on this ROM.
[MTCD Software Development] zerozoneice:
this default 9.0 UI must be the nicest and cleanest interface i've ever seen on a chinese HU.
[MTCD Software Development] Clandaries:
OK.

First i have to say thank you. That was quick. (Android 9.0)

Then i have to say that 9.0 is running smooth on my testradio.

I hope we will see a custom ROM based on Android 9.0 very soon :)

I did a mistake.When i first open viper4android app, i didn't gave root permission.How can i fix this?
[MTCD Software Development] Clandaries:
You have used SD_Firmware_Tool to build a recovery install SD?

1. open SD_Firmware_Tool.exe

2. Choose your SD-card, then choose bootcard.img

3. copy sdupdate.img overwrite if asked.

4. Put SD-card into GPS-slot. New recovery will be installed. After this the new recovery appears.

5. I had to use a USB-stick to install the Android 9.0 firmware. When i tried SD-card it just stopped.

Regards
[MTCD Software Development] tw39515:
yes thats exactly what i did. the sd card hangs and never reboots into recovery to install from usb. hmm will wait and see. i wonder if it has to do with my mcu its mtce-xrc 2.94. Thanks TW

I tried to create another catlog file (Attached) but I don't think it contains extra information. I also tried to set the language to dutch but it doesn't make a difference. The error message from the app also doesn't contain a link either. If there is anything I can do the create a better log I can do.

I will also check if downgrading the ECU to an older MCU version will work.

Can you tell me which file from "Y Series_PX5_9.0_ota(20190322)" you used to replace sdupdate.img (update.zip?)? And is the new firmware pre-rooted?
[MTCD Software Development] tw39515:
the sdupdate.img was from the Hal9k_Mod_3.x_upgrade_to_Android_9.0 folder that [MENTION=5092263]Hal9k_[/MENTION] provided. I dont know if the new firmware is pre-rooted. i would guess not, but could be wrong.
[MTCD Software Development] Sc4r3Crow:
Thanks...maybe I've done something wrong, because I'm a bit confused by the statement "The installation is similar to the installation of the Android 8 on top of the Android 6, which is described by first post.

update.zip should be taken from the archive Y Series_PX5_9.0_ota(20190322).zip. The assembly is made on the basis of this firmware." :confused:
[MTCD Software Development] tw39515:
1. open SD_Firmware_Tool.exe

2. Choose your SD-card, then choose bootcard.img

3. copy sdupdate.img overwrite if asked.

4. Put SD-card into GPS-slot. New recovery will be installed. After this the new recovery appears.

5. put update.zip from the archive Y Series_PX5_9.0_ota(20190322).zip on usb to flash from new recovery.

Thats what i got from it. But it wont install new recovery from sd card.
[MTCD Software Development] Sc4r3Crow:

updated via sd cards great!

I see alot of people asking for a simple guide for installing via sdcard. I also had some difficulties getting the correct combo as it has been a few months since I last flashed the rom.

1. put sd card into reader

2. open SD_Firmware_Tool.exe that was unpacked from the 'Hal9k_Mod_3.x_upgrade_to_Android_9.0.rar '

3. Choose your SD-card, then choose bootcard.img that was unpacked from 'Hal9k_Mod_3.x_upgrade_to_Android_9.0.rar'

4. dont change any other settings. create bootcard

5. copy sdupdate.img from the unpacked 'Hal9k_Mod_3.x_upgrade_to_Android_9.0.rar' onto the sd card. this will overwrite the sdupdate.img that is already on the sdcard.

6. Put SD-card into GPS-slot. either reboot device, or if you have an old version use 'mod installer' app.

7. New recovery will be installed. After this the new recovery appears.

8. when it tells you 'done doing actions remove sd card', remove the sd card.

9. Next go back to your computer and unpack 'Y Series_PX5_9.0_ota(20190322).zip'

10. copy 'update.zip' that was unpacked from 'Y Series_PX5_9.0_ota(20190322).zip' onto the sd card.

11. put sdcard into GPS slot.

12. select 'install from update'

10. select 'from sdcard'

11. done.

I know it's been written many times already but obviously not well enough because people are still having issues.. I tried to address the confusion regarding the multiple files with the same names between the .zip and the .rar.. People are still asking for help so I am only trying to make things more clear.

Reading the original instructions, I can see where people are getting confused, so it took me only a few minutes to write something that clarified those points. I dont see why clarifying and helping others is a bad thing... *shrug*

Possible to root afterwards without installing new rom again?

I never said, that it is negative to help people.

But i tell 3 times, this should be enough. Ask 4 times i dont answer anymore.

The problem nowadays is, that the humans are so lazy, they could but they are not willing to.

BTT.
[MTCD Software Development] CMDRKeen:
I think the issue is that people here speak many languages and we are all communicating in English. Some things seem to have gotten lost. We are all in this together, so I am only trying to help where I see a possibility of helping. If it is difficult for me, a native english speaker, to understand what you are saying, than I imagine others might have more difficulty. ;)

It is just a base rom.

Just restart your HU and connect to the Internet.

Try to execute the following command in the terminal:

It should give the size of the internal flash drive.

What will it answer?

Indeed, there is nothing new in this log.

@Hal9k_

Do you think you can maintain both PX5 and PX6 releases of Android 9?

It will be simpler for you to apply the same mod (same changes) for both architectures? I guess the android might be pretty much the same, different boot loader and kernel...

Regarding the "white" Android 9 interface (default launcher), at least on my PX6 the theme colour is controlled by a setting in the Car settings > Extra settings called "Brightness mode", see the attached photos.

usb problem

I have a USB Host Mode application that works perfectly. I plug in the device, Android pops up the Allow the app APPNAME to access the USB device? permission request window, I check the Use by default for this USB device tick box and tap OK, then up comes my app and it communicates with the USB device perfectly.

BUT...

Then I unplug the device and plug it back in. Android pops up the Allow the app APPNAME to access the USB device? dialog again. WTH? I've already told Android to do this by default, so why is it asking me again?

Ideally I want Android to remember I've granted permission for this particular USB device even after I've rebooted the Android device.

So why isn't Android remembering that I've granted permission?

But if I use the reset button I don't get in recovery mode. My Unit PT1839B Xtrons only do a Hardreset.

Exactly.

The unit reboots, but starts back into Android 8.0 from internal memory instead of starting from the stick.

Looks like the stick isn't bootable.

I can also get into 8.0 recovery and reboot from there, it still starts back into 8.0, and not from the bootimage on the USB drive.

Invariably I've seen many new (and senior for that matter) users ask questions already answered, then disappear, without any feedback or contribution to the to thread/community, which I thought was what XDA was supposed to be about. I.e. they get what they want and leave with zero contribution.
