Hello everyone, I'm having two strange issues when trying to update from Android 8 to 10 using Alex's OTG method.
I have updated the MCU (MTCE GS 3.44_3) and downloaded the latest version of RKDevTool and an HCT7 PX5 Android 10 IMG (20200612), as he recommended it directly (in the comments).

RKDevTool v2.74 recognizes my device and is able to start the process.
While performing the same steps as in Alex's video, it also does a "Reset Device" step (without problems). However, right after that comes the "Download Firmware" step which fails almost immediately (screenshot of RKDevTool). In Alex's video the "reset" step does not occur.

In the log file I get this error DownloadImage-->device did not support directLBA to write gpt
Full log here:

I'm guessing the problem is really the last error, but after looking for a while I can't seem to find an explanation. Does any of you know what this means?

I also noted that Alex used RKDevTool v2.73. Could the software be causing this issue? I tried finding older versions but without any success. If anyone has the 2.73 I'd like to give it a try.

Thanks!

I have exactly the same issue... I also tried with 2.73 and I receive the same error... you can find it on github project /rockchip-linux/tools/blob/118d3d2a0ce47af2561e07c891250e3e0293d80a/windows/RKDevTool_Release_v2.73.zip (I can't provide the full link as I'm new to this forum).

Alex 'got' the method from my thread.
Format storage first in maskrom.
Yes versions of rktool can yield different results.

Refer my thread for details.

Hi All, sorry if this is asked before as I am a newbie to this form.

The issue is, I am unable to mirror my Samsung A51 with my PX5. The EasyConnection app that I get builtin with the unit says something like 'This version is illegal to use with this software'.

I am not sure if Android Auto works in this unit or not?
Or if there is any other hassle free yet mature mirroring app I can use?

Try screen mirroring apps from the play store, or buy a Carplay/Android Auto Dongle, theyre pretty cheap.

Easy connected used to work.

The dongles work on any Android head unit running android 4 and above.

Just wondering how hard it would be to change a screen on one of these units?

I have a px5 for an Audi A3 and have cracked the screen so the touch screen only works in certain places.
I’m happy with the unit so have no need to buy a new one really so I’ve emailed xtrons who have said they can provide me with a replacement screen (at a cost).

Is it easy enough to do?
I’m pretty good with things and tend to do most things myself but I can’t find any info online/YouTube on how to do it and little electronics parts and pcb’s is something I’ve never played around with before.

This below is the exact unit I have

If it is a "normal" Chinese unit you can relatively easy replace the screen or the touch digitizer. At you tube there are movies about it. The problem will be to find the right spare part. But when you take it apart you might find some indication about the typenumber etc.

I bought it from xtrons and gave them their model number from the email they sent me when I bought it and they said they could provide me a replacement so hopefully it would be the right one with me giving them the model number.

Hi guys,
I have Eonon 2170: PX5 1024x600 A 8.0.0
MCU MTCE_WWW_V2.80_1 Mar 1 2018
BT WQ_BC8

long ago, I've tried A9 update, first, it wouldn't install, after an update from XDA, it installed but not everything worked properly, hence I went back to manufacturer's build, etc, as I also had some BT trouble on hands free, intermittent disconnect.

anyhow, I guess by now A9 has been fully debugged..?

so, what should I try, Android 9 or 10 ?
is there any must do, can't do before I try ?
what's the 'best path forward' ?
thanks for any tips or ...

All versions of Pie are buggy, factory or custom (customs are just modded factory ROMs anyway).

Having said that the bugs arent to do with BT or things no working properly, theyre mainly random reboots.

This picture should show how to get it.
Hi, I have my lanewatch camera is not working.
When I turn on the right signal, it shows black screen and says no video signal.

On my wiring harness, it has 2 yellow rca cable. One says Camera back in and Video in. (see pic)
I'm not sure if I have the right cable and am looking for the cable that has right camera cable input.

Do you have a picture of yours that can share?
And what is the yellow rca labeled for lanewatch camera?

Thanks.

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

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

    Post 2: Firmware
    Post 3: Tips, Tricks and Fixes - Rooting instruction here
    Post 4: Bugs/Issues
    Post 5: Useful apps
    Post 6: Useful links

    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
    Features:
    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

    DAB+ USB Tuner
    TPMS
    4G/3G Dongle
    OBD02 Module
    Camera
    DVR
    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
    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

    Manufacturers.
    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:
    ______________ _____________

    ANDROID 8 (Oreo) stock Update List:

    ANDROID 6.0 -> ANDROID 8 UPGRADE WARNING
    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 :
    https://forum.xda-developers.com/showthread.php?t=3736950
    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:

    https://forum.xda-developers.com/an...px3-5-headunit-mod-recover-flash-som-t3766892

    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:
