Hello,

Is it possible to upgrade to the last firmware of april if I am running hal9k custom rom ? As segu45 said, I'd like to check if the radar works the way he described. Thanks.

I've updated since the rom hal9k and everything works fine so far. After that you don't have root and the more functions you have put. keep in mind that you put a stock version. It's not necessary to do a hard reset, by it's recommended.

You have to upgrade your recovery system prior to use this ota upgrade....if you are on 8.x.x recovery system version you can't use this ota.

With the instructions provided and video on hal9k thread it is easy to succeed

Yes...it is possible...but you need to downgrade your recovery system to the 8.x.x.stock one first.

I am guessing that you should be able to update to Android 9.0 withouth changing the recovery, as if it were the case the rom wouldnt be available to current devices and only for the new PX6 device, but its a matter of testing and seeing :D

Hello,

I'd like to try android 9 for my PX5 HU. I found an hidden SD card slot on the right side of my unit, but there is no card in it. How do I update my recovery then ? With an USB key ? The actual one is V8.0.6..

Thanks for your help.
[MTCD Android Head Units General] ikerg:
You must use the sdcard slot to upgrade the recovery to 9.x.x version

Follow this thread instructions:

Instead of downloading the zip file (Y series.....OTA.zip) download the one provided by dasaita for dasaita specific ui on android 9.

Yes I read this but my unit has no SD card that I can unpplug. There is a slot on the right side behind the screen (but it's empty). Maybe there is another one inside.

This is my unit :

Edit : I may have finally understood. I juste need an empty SD card. I though I had to use one from the unit on which i'd found the original img file to replace.
[MTCD Android Head Units General] ikerg:
Yes. You need to use that hidden sdcard slot for the recovery upgrade.

Once upgraded..you can use the update.zip file provided from any USB as a normal update.

Having a hidden sdcard slot limit the functionality in benefit of visual appearance (bigger screen with no frames) . You can add an sdcard extensor cable to the glove box

Dasaita has the same interface for android 8 and 9 (for px5)

I dont know which manufacturer is responsible of new interface provided on the thread I pointed to.

All software is made by hct but by specific order.

Perhaps is the native hct android 9 UI

The android 9 rom on the thread of hal9k is older (march);than three dasaita one (april)

In my case I have issues with android9 as the USB ports are not mounted. I have to reboot each time

Can you tell me where i can download the recovery 9.0.5? I have a unit without a sd slot only 2 usb's. can i use a normal usb stick instead?

thanks in advance
[MTCD Android Head Units General] ikerg:
Each Platform (PX5, PX6, PX30) needs its own recovery for Android 9.

They are not compatible between them.

If you got the REcovery 9.0.5 from the thread I pointed to (for PX5 only) and upgraded into your system....only it will allow for PX5 Android 9 updates...and it will give you error when using PX6 Android 9 updates.

I dont know if somebody released a recovery upgrade for PX6.

---------- Post added at 08:41 PM ---------- Previous post was at 08:31 PM ----------

Read a little bit:

On the thread I pointed to: (https://xdaforums.com/showpost.php?p=79357076) there is a link for the REcovery System Upgrade with a Video attached that show you how to use the tool:

Link: Hal9k_Mod_3.x_upgrade_to_Android_9.0.rar

Video: Go

Use a FAT32 formatted Micro SDCARD (not bigger than 8GB) [USB cant be used to upgrade the recovery] and use it for the Upgrade of the recovery

Once recovery updated (The SDcard will result in a boot card with all automatized operations) the new recovery will be loaded and shown in display

Copy the update.zip (PX5 Android 9 Update) from one of the following links to the Root Folder of a USB Drive:

PX5 Android 9 Update - March 2019 - Unknown Source - New UI --> Y Series_PX5_9.0_ota(20190322).zip

PX5 Android 9 Update - April 2019 - Dasaita - Blue UI (same as Android 8) --> PX5 HA_px5_9.0_ota(20190415)

Move into the recovery Options to "System Update"

Select "From USB Storage" (remember to unplug other USB Drives connected)

and Voilá

Hello everyone...

Anyone know info on the sub pre amp output such as low pass frequency?? Are they are going to update the EQ for more control on this. Adjustment for different low pass settings, phase and such. Not just level output..

P.s... alternative app for these features maybe?

Thx.
[MTCD Android Head Units General] typos1:
AFAIK, like MTCB/C units, MTCD units have an audio chip that has the capability of this but its not enabled and to enable it would require someone who knows the MCU code incredibly well, well enough to be able to write this feature into it and there isnt anyone who does.

This is because the audio is controlled not by Android but by the MCU. The solution, however, is 7floor's sound mod, which, after some very basic soldering removes control of the audio chip from the MCU and hands it to Android, this gives a noticeable improvement in sound quality and adds extra features such as being able to adjust the sub level etc.

It was written for MTCB/C units but [MENTION=6738895]kumarai[/MENTION] has also done it on an MTCD unit running 5.1.1. the app should also run on 6 and 7 units but AFAIK no one else has tried it on MTCD it yet, you can install the app without doing the hardware mod to check that it runs. Theyre very clever these Russians. The thread about it is here :

[MTCD Android Head Units General] roxylove:
Sorry for what seems like a silly question, still learning about this system. Are these two units the same? I ask because the listings SEEM identical, but the Ali express listing clearly says it is the 4600 whereas the ebay does not (but has all the same properties). Also, the color description is different, despite having the same information.

https://www.aliexpress.com/store/pr...ith-Octa-Core-2GB-Ram/600991_32803295957.html

http://www.ebay.com/itm/10-2-Highla...ighlander-Navigation-/262884374207?rmvSB=true

Looking at pics, any idea where the micro sd card would go? Maybe the top of the unit?
[MTCD Android Head Units General] typos1:
"The 4600" ? that means nothing, thats just a made up name by the seller, Dasaita.

Both are octacore MTCD head units.

The crucial things to know are that they are MTCD (I dont think there are any other octacore units on sale so thats an easy one), the screen res (800x480 or 1024x600), the processor - RK3188/PX3 or RK3368/PX5 and possibly the manufacturer and this has to be guessed by looking at the back if theres a picture in the listing or if youre lucky seeing a screen shot of the settings/about device screen.

Basically there are about 15 companies making these head units to pretty much exactly the same spec with very minor differences (like the tuner or amp IC), all the SoMs (the boards the Android system sits on) are made by one company (HCT) and all the software is made by MTC.
[MTCD Android Head Units General] roxylove:
Gotcha..thanks for the info. Definitely a px5 process (according to the specs) and both also have the same 1024x600 screen. I was just confused because both are dasaita units yet have some slightly different advertising. Any idea of the micro sd card? I don't see a slot anywhere in the pics.

Sorry...I also meant v600 not 4600 (the Ali express pic says v600 and eBay does not)

Does anyone know if the latest firmware (7/6/17) already has the latest MCU (2.56) included as the dmcu.img. Or, should I remove the dmcu.img with the 2.56 download?
[MTCD Android Head Units General] typos1:
Depends where you get the firmware from, maybe a good idea to remove the MCU part if you cant see anything that tells you which MCU it is.
[MTCD Android Head Units General] roxylove:
The firmware I'm talking about is on the first page of this thread. Does the latest firmware (7/6) contain the latest MCU (2.56)? Unless is there a way to tell before your flash it?
[MTCD Android Head Units General] typos1:
I ve no idea if it does. sometimes its included in the image not separate.
[MTCD Android Head Units General] roxylove:
So, do you follow the same process to update via USB? Place on root of drive, go to settings, update?

I ask because I just received my unit today and the MicroSD card is back behind the screen. There is no way I can take this out every time I want to do an update.
[MTCD Android Head Units General] typos1:
Yeah, but it may not auto detect via usb, if it doesnt your ll have to go into recovery yourself.

Thats a stupid place to put the SD slot !! What if you wanna listen to music from SD ?

If it was my unit I d undo the screws and extend the wires and out the SD slot somewhere more logical.
[MTCD Android Head Units General] ikerg:
You should get a high capacity sdcard to avoid removing it each time and copy the update file from usb to sdcard each time you want to update...and to store maps and music

Or just use the usb port for update...but ensure you remove any other stick from other usb ports. My unit detects perfectly the update.img on the root folder of the usb and suggest the updating procedure

[MTCD Android Head Units General] roxylove:
I definitely don't want to hold that reset button with a toothpick each time I update. Is there an app to boot into recovery without having root? Getting installed tomorrow so I'm hoping it'll auto update like your USB.

Stereo only came with 1 USB, which is fine, so won't have trouble with others, but will the stock file manager have ability to copy from USB to micro SD?

I'll probably just load the latest firmware and MCU on SD card tonight and will try the update tomorrow, then fool with the work around from there. Are you running stock or the malaysk rom? Not having played with either yet I don't know the benefits.
[MTCD Android Head Units General] roxylove:
Given the location of that sd card location, is there any harm in loading the most recent firmware/mcu prior to the first boot? Wasn't sure if there was an initial boot that I would mess up with those updates on there.
[MTCD Android Head Units General] ikerg:
I don't think you were able to get into recovery at the very first time if never tried before....so you will probably boot once normally..

Anyway it is not a problem to boot normal...copy new update to usb...and update.

[MTCD Android Head Units General] roxylove:
Gotcha - I was referring to though as loading it on the sd card the first time (since I cannot access it again) and updating the easy way through the settings. Future updates I will have to enter recovery, or hopefully transfer from USB to sd card with an app.
