Issues with Android 9.0 on Pumpkin radio ( MCU MCTE_KLD -2.94e)

Hello guys,

I'm currently running Hal's android 8.0 rom on my head unit and it works great! I really want to flash android 9.0 but when i do flash android 9.0 on my head unit, the head unit would freeze and do a reboot. (mostly on a cold boot) The unit would be stuck in a boot-loop until i hold down the power button for about 8 seconds and it would boot about 3 times before it loads back up again. I have searched everywhere on XDA for some help but no luck. Has anyone have this same issue? i've tried upgrading my MCU file. i have tried to turn off and on certain settings to troubleshoot. but nothing seems to work.

Pumpkin stereo

4gb /32gb

MCU : MTCE_KLD_2.94e

yes you're right

you have to study one of the steering wheel key or panel key as voice command(it has a microphone shape) then through that button you can access google assistant

Your seller is witson. https://www.witson.com/product.html

You will not find any firmware in their website. Just look here in XDA for them.

I tried to update to several versions now with my Android 9 System and I even tried to re-install the recovery as if I would be updating but I am stuck at "Verifying the Update package" all the time, it never goes past this step. It seems to be reading my USB drive forever, I waited more than 30 minutes and it didnt complete. Any idea what might be going on here?

So,

have a seicane head unit and over the last 6 months or so have updated it a few times with the latest firmwares on this thread. Last one was the Aug 13th update which I installed yesterday...

I've searched and searched, and I don't believe I am the only person with this issue, but cannot find a single thread about it -

Google Earth installed on the head unit and it just refuses to display the base layer map. I get roads, 3d buildings, placenames etc etc - everything apart from the underlying map - just black.

Strangley, other satnav software for android such as TomTom I got the same issue - the base map just doesn't appear in 3d mode.

Is this a firmware issue that might be resolved in some future release? Anyone else have the same issue?

[MTCD Android Head Units General] SomebodySysop:
Yes, I have the same exact screen. I have read that this means your sd card is bad, so you would try installing firmware tool on another sd card.

In my case, the firmware tool is unable to mount my internal drive: /mnt/internal_sd. I am still searching for the answer to this.

Just got a this new PX5 unit the other day. I am hoping I can upgrade it from 8.0 to 9.0. The sellers havent been the greatest at customer service. My manufacturer is HT. Didnt see it on the list. But HTC is mentioned in the build number. I am guessing I should use the MX software date 8/13/19. Is this correct? Trying to post pics of info. Thanks in advance. And yes. I have read the the beginning of the thread. Dang. Cant get the pics to upload. Just fyi. The brand is Eonon. I know that doesnt matter.

Why replacing the coreboard.

Just follow the instructions to make your own otg cable.

Extract the coreboard and connect it to the otg cable...and to the pc...is an easy procedure and you can solve your issue.

A new coreboard is at least 100usd

[MTCD Android Head Units General] Greentiger00:
Well. I went ahead with the install. Everything went great! Worked perfectly. Used MX software date 8/13/19. Car Launcher app installed and worked perfectly. Still have issues with steering wheel controls. Cant get call pick up and hang up to work. But I think that's because of my car. It's a 2012 Mazda 6 and I think the bluetooth in that model was separate from the radio. If anyone knows of a way to get these buttons to work, it would be greatly appreciated. Either way! Totally happy with 9.0! Thanks so much guys for all the hard work! I hit the thanks!!
[MTCD Android Head Units General] SomebodySysop:
Yes, you're right.

I've been thinking through this further. Any way it goes, it appears I'm going to have to pull this thing out of my dash. I've had the unit for 2 years and it has mostly worked very well. I was figuring on replacing it at some point, and looks like that point is now. I want to get an Android 9 px5 which will give me the 4gb ram, 64gb rom and larger screen that I seek. Then, if you come out with android 10, I'll use the mod installer app to upgrade!

I'll see if I can fix the coreboard in the old unit, and if I can get it back working, just keep it for development, or to sell or even to donate to a developer who needs a px5.

Win-win. If I run into any problems, I'll use the OTG thread to try and resolve them.

Again, thanks!

Hi all,

I just bought this PX5 unit for my Peugeot 407 and found this forum so this is my first post :)

After installation I noticed some issues when using the unit: automatic headlight option didn't work anymore, boot is locked and can be opened only using remote and parking sensors are not functioning properly anymore after I tested car's own PDC button. Now parking sensors are totally disabled, button is always activated and nothing happens when I press it. I also tried to change back to car's original head unit but it didn't solve the issue.

Then I found this forum and deciced to try firmware update. I think the update went as it should but neither this solve any of the problems. I found option to update MCU also but I did one big mistake - I didn't take any backups though the update was ok. But of course all the factory settings disappeared (CAN BUS settings, BT module option etc.) and I also got "Version unmatch" notification (did I updated a wrong MCU file?). After I while I found a solution to get rid off the notification (used unlock app) and also proper factory settings. I think now the unit is working as it should though automatic headlights, parking sensors and boot locking is still a mystery and can't be changed from the car settings.

But I noticed that now some apps that I have installed are not working because "the device is rooted". Is there any way to solve this?

Unfortunately I didn't take a screenshot about the original firmware versions etc otherwise it was Android 8.0 and MCU was maybe version 3.01. Here is what is shows now:

[MTCD Android Head Units General] eNubiX:
Your MCU version looks wrong. It should be HA_3.30. I have provided a HA_3.30 (sound patched) file for you. Try it. It has volume and sound levels adjusted for higher quality sound. As for the apps not working because of the system being rooted, try and go to administrator mode and turn off USB Debugging mode. That is what worked for me. If you don't know how to get to administrator mode, let me know and I will give you instructions.
[MTCD Android Head Units General] p407:
Thanks, I'll try that MCU version! Can I just normally do the MCU update (or downgrade in this case?) via unit's setup using that file? I'm not sure how to get to administrator mode so please send me the instructions, thank you! :)
[MTCD Android Head Units General] dpalacios:
Suddenly my dasaita radio doesn’t have sound with speakers. I don’t understand why.
[MTCD Android Head Units General] nic2k:
My first guess would be the amplifier chip stopped working probably from a bad solder joint. If you connect a set of amplified speakers to the line out do you get sound?
[MTCD Android Head Units General] eNubiX:
1. You must extract the dmcu.img file from the file I sent you and install it as you would normally by placing it on a flash drive, or SD card.

2. In order to get to admin mode, you need to go to "Settings>Factory Settings" then type in ADBON into password section. That should enable admin mode on the regular "Settings" menu. Inside admin menu, you will find USB Debuging option. Turn it off. Hopefully that will help with the rooted apps problem.

Hi guys,

PX5 MTCE unit (MX). For what is this grey wire from the board out? It goes out of the unit for few centimeters more and ends up isolated.

Grounding?
[MTCD Android Head Units General] tw39515:
looks like wifi antenna, someone correct me if im wrong.
[MTCD Android Head Units General] nic2k:
You are correct it's the sad sad WiFi antenna. Notice it comes out right next to the WiFI controller chip.

Me40, is there a metal plate under the red cardboard piece?
[MTCD Android Head Units General] me40:
Didn't check for metal plate. I asked today the seller - he said it's noise cancel wire (whatever it means). In fact I was curious because when no music or too quiet from the speakers I have small cracking noises so was wondering if I have grounding issues or something like that. But he couldn't explain me what should be done with this wire anyway.
[MTCD Android Head Units General] diegudio:
Hi guys,

it will be much appreciated if any of you with experience in these units can take a look at my problem.

I opened a post to share the details (sorry, I haven't seen this one before), but I cannot copy the link here, as I'm a new user. You will find it as "...Skoda Fabia Mk3 px5 unit buttons not working"

In a nutshell: the px5 unit I bought for the Fabia from my wife has the front panel buttons and knobs dead, but the touchscreen and Android functions seem healthy. The Fabric Settings Key menu is also not solving the issue: the buttons wouldn't be detected either.

I plan to send back the radio for a refund, but I wanted to give it a last try before, as it looks really nice.

Any help?

Thanks!!!

Hello colleagues. I have a dedicated radio for Audi A8 D2 with the px5 motherboard. (Model-PX5(1024x600), Android 8.0, compilation nr 8.0.0 OPR5.170623.007, MCU version: MTCE_HLA_V3.08_3)

I have read it but my english is not the best.

I did this:

I have 2 micro SD slots on my radio, so I prepared a microSD card as described in # 2 and the file with unpacked Android 9 (HCT4_PX5_9.0_Ota (20190813). 7z) I put on a 2GB flash drive.

But the problem is that my joy does not respond to launch from the previously prepared microSD card. How to do it to start from this card? Pressing the reset button with a paper clip does nothing.

If you prepared correctly the bootable sdcard as the guide explains.,.(format to fat32 first, use the program to make bootable and replace the specific file for Android 9 recovery) and your unit does not boot from sdcard when you reboot ....then your sdcard slot is not useable for this purpose....

Use other methods as mentioned in the same post

[MTCD Android Head Units General] ikerg:
No

You have to upgrade your recovery first by means of preparing a bootable sdcard.

Once appeared the recovery menu in display (with version 9.x.x - I don't remember exactly) you can upgrade system from the options appeared

Then in the USB device (or in other sdcard) place the update.zip (decompress the .7z file) and perform the upgrade.

How-To use PX5 for Rear Seat entertainment?

Hi,

I'm using a MTCE CZ 2 DIN universal PX5 MTCD Head unit. ([de.aliexpress.com/item/32657757770.html?spm=a2g0s.9042311.0.0.4d584c4doettSW)

I'm trying to achieve a Rear seat entertainment solution with this unit, i.e. app sound and video to rear out and radio / music on main screen.

Does anybody know how this is possible with PX5 ?

Kind regards,

alex
[MTCD Android Head Units General] sergialess:
My brother in-law tried to get video out to the rear seats and no luck. Why? just because the unit does NOT implement video output (said by the seller). Good luck.

I've bought a unit with "full video out". It works indeed, but in only mirrors the front screen. so it is not really useful for Rear seat entertainment. Is there any known solution to assign apps to video out ?

Subwoofer

Hey guys,

I have a Isudar PX5 head unit

I have the amplifier connected via RCA to the 'Subwoofer Out' connection on the radio.

Everything works OK at first, but after shutting down (turning off car/leaving car), the output is not working. I can hear the subwoofer just 'throbbing?' But no respons.

Only way to get it back to work again is to disconnect the radio from the car and reconnect it. (Now i am taking out the car's radio fuse and putting it back in).

Can anybody help me with this issue ? ? ?
