Successful install. Edited Instructions

I've just successfully installed this ROM and upgraded from 6.0.1 on my Dasaita V600 unit with MD725 Type 1 Bluetooth module. Donation Pending.

Two points.

1> A link to this thread needs to be added to ikerg's 'MTCD PX5 Headunits Repository & information (Stock & Custom)' thread since he aims to consolidate all useful PX5 info.

2> I found the instructions confusing at times, so I have attached an edited version for your consideration.

Peter.

Known problem: If you have a Bluetooth module MD725 type 2, it will not work in Android 8, although Android 6 works, as does an MD725 type 1.

The reason is that from Android 8 its driver was removed.

How do you know if you have such a module?

On the first page of the factory settings in the BT item, MD725

The command getprop bt.md725.type, executed in the terminal, answers with the type number “1” or "2".

If you have Android 8 installed:

Download and unpack the archive: Hal9k_Mod_3.0_MTCD_MTCE_PX5_1024x600_800x480_eng.7z

Install the ModInstaller.apk application on the HU, run it and click "Install".

It is in the archive with the firmware.

Root access is not needed.

HU will reboot in recovery.

Insert the USB flash drive with firmware file update.zip into the USB connector of the radio. It must be formatted in FAT32.

I recommend to take out all the other flash drives, SD cards, modems and other devices from the radio jacks.

Select the menu item "Apply update system" - "From usb storage"

The firmware will be installed.

(You can use the SD card for installation, but it will be much slower.)

Select the menu item "Wipe data / factory reset".

The user data will be cleared.

Select the menu item "Reboot system now".

The device will reboot in Android 8.

If you have Android 6 installed:

This method is also suitable for a full recovery of HU with Android 8 or 6 if it does not boot, including even in recovery.

Download and unpack the archive Hal9k_Mod_3.x_Android_6.0_upgrade.rar

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

Download the 'Rockchip SD_Firmware_Tool.exe' to a convenient Windows PC which has a micro SD card reader/writer attached and 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, although you may have to allow up to 30 minutes for the internal capacitors to fully discharge.

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

HU will reboot in recovery Android 8.

Insert the USB flash drive with firmware file update.zip from the Hal9k_Mod_3.0_MTCD_MTCE_PX5_1024x600_800x480_eng.7z archive into the USB connector of the radio. It must be formatted in FAT32.

I recommend to take out all the other flash drives, SD cards, modems and other devices from the radio jacks.

Select the menu item "Apply update system" - "From usb storage"

The firmware will be installed.

(You can use the SD card for installation, but it will be slower.)

Select the menu item "Wipe data / factory reset".

The user data will be cleared.

Select the menu item "Reboot system now".

The device will reboot in Android 8.
