maybe a stupid question, but I couldn't find it: will there be OREO Rom's for PX3 HU's?

Or do I need to buy a PX5 Board to upgrade to Oreo?

I don't care about a few months, but just to know

(MTCE_MX_V2.65_1)
[MTCD Software Development] dsmckelvey:
I can confirm this worked for me. I was not able to install Malaysk afterword by the recommended method through the Android Settings Update method. It went to diagnostic screen with a RGB pattern and GPS data. I thought I bricked it. I then tried replacing the img file on the same SD used to downgrade to 6.0 with Malaysk's ROM and repeated. It installed fine. Be patient. There is an initial black screen that takes a while.

I have an new HU XTRONS PX5 4GB ram with 32 GB memorry and Android 8.0 Oreo

BUT! this unit have a new version of MCU: MTCE ...not MTCD

MCU version: MTCE_GS_V2.76b_3 Dec 25 2017 10:08:27

Does have this importance?

1. Cam I use Kumaray metod for rooting?

2. Can I will use ROM`s from Malayska?

T H A N K`S !
[MTCD Software Development] bettuccio:
MTCD and MTCE is the same thing. MTCE is just a software update of MTCD. The Malaysk rom is based on Android 6 so you should go back down the recovery in 6 to install it. in the Rom of Malaysk (android 6) the root is already included.
[MTCD Software Development] marchnz:
Yes, the drivers are there, otherwise WIFI wouldnt start. For those wanting to help in the discussion of Bluetooth not working on Oreo - see this thread for details.

I got the same error only on a Dasaita hu. It has a single sd slot but there is a footprint for another. I saw in root explorer there is a symlink for external_sd rather than a regular folder. Perhaps the sd needs to be connected somewhere else?

Hi guys today i received a new dasaita vw headunit

Can someone tell me where i can find firmware files for this unit can i use the 8.0 firmware files from the hotaudio px5 2gb thread ?

My unit has this firmware preinstalled
[MTCD Software Development] xdamember2:
This is the latest known 8.0 ROM:

https://yadi.sk/d/umCvHqCDzHccr/RockChip PX5 Android 8.0/GS

I have no issues with it. The hotaudio updates are "ota" and I'm not sure what that means.
[MTCD Software Development] hv006:
Hmm ok

It looks like my pre installed firmware is newer

I dont like the statusbar i want to hide it

I can confirm that it works on GS. Few times I had to reset using button and flash and clear data and I think after 5th try it booted property.

Update: Don't install it yet. I got boot problems again after hard restart. Something is wrong. I don't think its full Root.
[MTCD Software Development] xdamember2:
After recovering, did it still have root? If yes could you give more details about how to recover? Is the procedure like 6->8 upgrade or root patch? Which firmware is selected for the bootable builder?

[MTCD Software Development] greg_z:
Just follow procedure for installing Oreo.

I think we have issues with boot.img. That Root update is changing it and it's not compatible with our units. Maybe somebody needs to patch it on gs unit. I'm just guessing.
[MTCD Software Development] Mad_Mod:
I am 100% agree with your findings (reply) and for this reason I have kept it short, this root is not compatible yet with our GS headunits.. just wait for the master Kamarasky and his new 8 Oreo rom, he is currently busy with baking it.

[MTCD Software Development] k0sTi:
Hi all,

after installing Oreo using the steps from [MENTION=6738895]kumarai[/MENTION], can I use the latest OTA updates from Dasaita?

(or can I use them in the update process already?)

Thanks!
[MTCD Software Development] warata:
Yes you can.

However, HA(HTC3)'s oreo is useless that does not work split screen and PIP,so at this time I think that GS's oreo is the best.

On my MX the GPS SD card slot is not the true GPS SD card slot, MX used a USB to SD card adapter. Even if I installed the true GPS SD card slot it did not work since I could not get in to recovery after the update since I don't have any power button and Alt+PrintScreen+E did not work.

[MTCD Software Development] bettuccio:
You took away the doubt. I also thought that the microSD reader was not enabled to boot. So you managed to install the recovery 8 but then you could not log in you got the gray screen and that's it? Then how did you recover you installed recovery 6 again?

I wonder if one day there will be the possibility to install the recovery from USB for us that did not work by doing a specific boot from USB. Or we have to keep Android 6 forever.

I was expecting to find several pins for usb and I only found a USB-DET labelled pin.

Enviado desde mi SM-G950F mediante Tapatalk
[MTCD Software Development] marchnz:
SOM header pin 29 & 30 - ARM-DP & ARM-DM. You will notice these signals at the USB42 / U27 IC. If the Chinese designers didn't mess up, we would all have OTG without modification as this is what this switch is supposed to do! I.e. when power is supplied by OTG cable, switch to OTG. But they messed up, the USB hub preventing it correct operation and haven't apparently wanted to fix it, but seem OK to install a USB switch that is effectively redundant.

I proved this with my GS board as - not every MTCD has the USB switch U27 FSUSB42, nor do all MTCD have USB 0 (which is meant for OTG) out to a connector. My JY board for instance does not have these items.

I use the GS schematic.
[MTCD Software Development] marchnz:
Quick progress update.

Thanks to [MENTION=7329495]xdamember2[/MENTION] I have a Oreo PX5 SOM. It is working in JIG and able to get Loader mode.

Issue I now have is that using rkdump, I get almost all partitions extracted except for [system] as loader is reset by a watch dog, which breaks the extract. I'll try android tool instead as this apparently enables single partition extract, so might get system partition before reset.

If that doesn't work, I'll look at what is causing reset - if MCU I can possibly work around it.

Good news is we have loader and recovery partitons.
[MTCD Software Development] typos1:

[MTCD Software Development] KoTiX2:
Can't you use the system image included in the ota? I mean after converting it to IMG?
[MTCD Software Development] marchnz:
No, but I wonder if the .zip can be applied through recovery. Can anyone check their Oreo recovery to see if the zip can be applied in recovery?
[MTCD Software Development] KoTiX2:
Can you explain me why is not possible to use the system.img extracted from the ota?
[MTCD Software Development] marchnz:
There is no system.img in zip. .zip or OTA updates contain a script which builds/applies partition and files including permissions and symlinks.
[MTCD Software Development] typos1:
Good point - does the O recovery have more features thsn MM recovery ?

Each version seems to. If it can flash zips that would explain why teh update was zips.

And it may mean that the method I suggested weeks ago (making an Oreo bootable sdcard, sing that to get into Oreo recovery and then flashing the Oreo update from there) could work . . . if we can make a bootable Oreo sdcard.

I installed [MENTION=5092263]Hal9k_[/MENTION]'s N ROM on an L unit using this method, but I havent managed to get into N recovery this way on an MM unit.
[MTCD Software Development] KoTiX2:
OTA update contain the DAT files that can be easily converted to IMG using this tool:

https://xdaforums.com/android/software-hacking/how-to-conver-lollipop-dat-files-to-t2978952

I did it and i used the standard rockchip tools to extract all the files from the IMG files.

This are the converted img files:

If you have recovery.IMG and kernel.IMG will be easy to build up the firmware image with SergioPoverovny tool for example.
[MTCD Software Development] typos1:
Which tool is that ?
[MTCD Software Development] KoTiX2:
It's a python script to convert DAT files to IMG

you need to install python first and then run the sdat2img.py script
[MTCD Software Development] typos1:
Hmm, I ve got MTCD ROM Builder on my pc it may use the same script.

Got Python already too.
[MTCD Software Development] marchnz:
Great news, thanks for your informative and helpful input! I'll share those files with you this evening when back.

I'm reasonably confident I can dump full image too - Initially appears that the MCU is the culprit and releases 3.3v rail. Theory is that I will bypass the MCU 3.3v control and force it on so that it can't 'reset' the SOM.....
[MTCD Software Development] marchnz:
Update - I have confirmed MCU is watchdog. This means that I can force SOM supply ON (+5) overriding MCU.

As an FYI - in MTCD world, [reset] simply powers off the 5v line to SOM.

Will try again to dump/extract ROM including system tonight. I'll also upload and share as soon as I have extracted.
[MTCD Software Development] bettuccio:
yes, I understand what you mean now. It is the same card to upgrade to the 4 GB RAM that I wanted to buy. At this point I could buy it with Android 8 on board.

I performed this upgrade on an Xtrons TB103AP Running 6.0 MTCD_GS_V2.58_3. Some added detail that may help others with similar units.

The initial extraction of the files is to a folder on your PC, not the SD Card.

When running the CreateCD, SD Firmware Tool, choose Update Firmware not SD Boot. I found when choosing SD Boot, Windows 10 could no longer read the SD Card and prompted to Format it. This blocked me from adding sdupdate.img file to the card.

The screen remains blank for several minutes before reporting Erasing briefly. Don't rush it. This video of a different model going through the same process was very helpful in showing the long periods of time without feedback. https://youtu.be/34GSX5aId8Q

My system did not go into recovery mode automatically after the initial install complete. I was able to trigger it with the reset button in the hole behind the screen. It is the same reset button that is used to navigate the menu as the soft buttons on the screen panel do not work for this step.

Hopefully these details will make the process smoother for future upgraders.

Also, the EasyConnection version that installed with this upgrade allowed me to connect a new Galaxy S9+ to my headunit. Despite upgrading EasyConnection when it was running on Android 6.0, it would not complete the pairing. The error was mob interconnection installation failed. It had connected with an S7 without issue previously.
