Hi, I'm pretty new to this scene and was hoping for some support and guidance from the community. I have recently purchased a 2nd hand car which had a PX5 head unit. I will post the device details below, but I was hoping you could point me in the right direction to download a newer and compatible firmware/mcu for my unit. I'm used to flash custom rom/firmwares on android mobile phones so I do understand the process itself quite well, it's just the firmware/mcu compatibility with this device that I'm unsure of. Thank you in advance for the support.

Hi friends, maybe someone has encountered something similar and can help me. I have a PX5 android 9 radio with DSP. Sometimes the sound completely disappears from me. There is no regularity, but I noticed that when I have no sound - the equalizer becomes simple, when there is sound - there are a lot of different settings in the equalizer. A couple of times I just updated the MCU and it seemed to help, although it was probably just a coincidence. Sometimes it is necessary to restart the radio very many times and the sound appears :(

      setprop persist.adb.tcp.port 5555
      setprop sys.rkadb.root 1
    2. On your PC, download latest "SuperSu" zip archive from official site, extract su binary from arm64 directory inside the archive
    3. On your PC, create new file called "rooting.rc" with following content:

    This thread is intended on collect the information about Android 8 (Oreo) over the Android units that features:
    PX5 Platform Core Board

    The information below is a copy of the same thread for Android 6 by @aarick

    For those not familiar with the PX5 Head unit, the specs are below:
    OS: Android 8.0 Oreo
    CPU: Rockchip PX5 A53 Octa-Core
    RAM: 2GB or 4GB DDR3
    ROM: 32GB
    Audio output: 4*45W
    Built-in Radio Tuner (RDS Enabled) (18 FM and 12 AM stations Preset)
    Built-in USB & SD Slot
    Region Free DVD Player
    Screen Mirroring
    Steering wheel controls (SWC) and Canbus interface
    Optional compatible accessories:
    DAB+ USB Tuner
    4G/3G Dongle
    OBD02 Module
    External Mic

    The head unit comprises of two parts:
    • a MicroController Unit(MCU) board, which controls physical buttons and A/V inputs/outputs to/from the headunit. This board interacts with Android OS.
    • ANDROID part. The main Operating System.
    Both MCU and Android ROM interact together to achieve the functionality of the head unit.

    MCU type discussed here is MTCD or MTCE (if your unit has not MTCD/MTCE type MCU this thread is not for your unit)
    MTCE is a software upgrade for MTCD, so they are identical in terms of hardware

    The Manufacturer is identified by the XXX when consulting the MCU information under "device information" [MTCE_XXX_Version]. Take into accout that you should always refer the MANUFACTURER name (not the seller) on the forums for help/assistance. Giving the name for the Seller does not give any information but confusion.

    e.g: MTCD_HA_1.93_1 (MTCD Unit with MCU for HotAudio under 1.93_1 version)
    e.g: MTCE_GS_2.75 (MTCE Unit with MCU for GESHI manufacturer under 2.75 version)

    Known manufacturers for MTCD/E PX5 are:

    MCU Upgrades Repository:

    ANDROID 8 (Oreo) stock Update List:

    Due to change in partition system and upgrade in recovery system, update can't be performed using the OTA Android 8 files over Android 6.0 as usual method (direct or Recovery) as it will result in an error (or could get a bricked device...)
    The only available methods are:

    1) Upgrade by using SDCARD slot:
    Thanks to @marchnz for the Oreo ROM Dumping, to @kumarai for the recovery change procedure, to @SkyBeam2048 for the compiled solutions for Upgrading/Downgrading (and the comprehensive instructions)
    The following Procedure can be used :
    Note1. Your unit MUST have a SDCARD slot with direct access to recovery (Not all SDCARD slots on all units can - some sdcard slots have been reported to be another usb port extension [USB3] and they will not work for upgrading)
    Note2. USB port is not able to upgrade the recovery as required.
    2) Upgrade by extracting the SOM and connecting a homemade OTG USB cable:
    Instructions for making the OTG cable:


    For upgrading via OTG cable it is recommended to use Rockchip Tools for the Android 6 to 8 upgrade from a PC (to put the unit into "loader Mode" and then flash the supplied firmware)

    Custom Oreo Firmwares:
    @Malaysk has been released a prerooted Android 8 image with several improvements and modifications:
    Received a new update from Xtrons GS-PE PX5 8.0 September 20th
    Someone might want to mirror it before it gets pulled.
