1. the bluetooth will not pair and show any devices
2. 3g will not work but the signal bar is showing a signal
i got in contact with the seller and they advised me to install a update. they sent me a update and i unzipped it and put on a sd card and installed on the my head unit.
after the update the vol , navi , power , screen in and out buttons all stopped working and the update didnt even fix the problem with the bluetooth and 3g problems.

Upgraded to 5.1.1 now only see a Blank Screen - Music and volume works

Hi,
so I am kinda new to this and wanted to upgrade to 5.1.1 below is the initial information.
Its a Roadmaster AN-111 GMC (if it matters)
It was MTCB - KSP 2.86
upgraded to MTCB KSP 2.89(KSP_11-28-2016_1.99_dmcu.img)
Firmware was 4.4.4_11032016
I installed the KLD - 2.1.1 december update
now the system boots up but does not show any display, if i plug in a USB it starts to play songs. All hardware button BEEP when i click so does the buttons on steering. I
I can go into recovery but I continuously receive the no sd card - cant post a picture yet
any chance of recovery please?

Hello,
Are you sure the MCU upgrade you did was to KSP 2.89 ? The filename you gave says something else: KSP_11-28-2016_1.99_dmcu.img (notice the 1.99 in the filename).
That would mean you did a MCU downgrade. Try flashing the MCU back again (i have KSP mcu too, not sure which version, i may be able to help you).
Regarding 5.1.1 update, i have the same behavior. I do not see the "desktop" with all the icons, but i see toast messages, popups, the "preparing to shutdown" window, so, maybe display driver problem ?

Trying to find stock firmware for KD-0234 HU

I have a Pumpkin KD-0234 and I've been trying to correct an odd issue for some time but I'm not really getting anywhere with Pumpkin's support. It all started in January when my google play services crashed. Did a bit of digging, found out which service it was and force stopped it. All was good until a few weeks ago when out of the blue my wifi would not connect to any network and I now have limited bluetooth connectivity. BT actually connects fine but not all functions work. For instance, when I'm playing music on my phone I can play\pause through my HU but FF and REW have no effect. My OB2 reader connects fine but torque cannot read anything from it.
All other functions are fine and I am certain it is all software related and so tried a factory restore only to find that it doesn't actually do a RESTORE (ie a full wipe and reset from scratch) but instead just wipes user settings and data. Many of the factory settings and element changes (ie LED colour setting) remained as I set them.
So, in contacting Pumpkin they did send me an update.zip file which did update my version but it still isn't a full factory reset that I'm looking for. Now...in trying to get the image.zip file they finally tell me that don't have it and can't help and they believe this is a main board problem. I'm not buying that answer and want to see what a full wipe and reinstall of the OS will do. But I can't do that without the image.zip file.
So...does anyone know where I can get the image.zip file or another way I can perform a full factory restore for my HU?

MTCD GS bootloop issues after RAM upgrade

Hi, so i went on a little adventure with my MTCD PX3 RK 3188 unit, first i wanted to experiment with some new RAM upgrades, so I tried quite a few different manufacturers and specifications as I work for a PCB/PCA manufacturer. But I think i have a pair that works now, cant remember the exact part name but it is manufactured by Micron 1 GB modules. The unit boots, and i can access recovery and flash roms without problems. The issue arises when it tries to bot the selected ROM, the unit shows the splash screen of the rom selected and then proceeds to boot the ROM with the flashing car logo. But after the car logo has blinked for a minute, the screen shuts off and the device reboots.
So, while fiddling inside the recovery menus I've discovered what i think might be the issue, firstly I cannot wipe the device, if selected the cmd prompts: "Data wipe failed"
But if i try to install a new ROM I can also observe that it does not update uboot.img because "E: Can't find uboot".
This leads me to belive that while I was experimenting with the RAM modules, I might have overheated the internal storage chip, in turn corrupting some data.
So now i need some assistance:
1. Is there any way to flash a new bootloader?
2. Can i change the internal memory chip and just flash the MCU and rom to it? How would i do that? Will it fix the problem?
3. Is there any other fixes that I should try?
Thank you for any suggestions.

Head over to OTG thread to flash ROM directly or scenario where eMMC is corrupt or blank.

I think you can try to use rockchip tools to erase the flash memory and to flash again your image.
As px3 and px5 are interchangeable....
Check on forums as there is some information of building a OTG cable for px5 to allow you to connect the coreboard to USB on PC and allows you to use rock chip tools

Pls help! Installing software from scratch on MTCE Px3 2GB

Hi guys,
your help please! I have a Px3 2GB head unit with the following:
- MCU MTCE_KGL_V2.70_1
- Androd 7.1.2
I was trying to update to the latest Malaysk version 5 and somehow during installation an error message appeared and the unit is now unusable. When turned on only the initial screen (Navigation system) is visible and nothing else, so I can only switch it either off, or on and it stays on that screen. I have tried to install a new software through USB and microSD but nothing seems to work.
Do you know how I can install the software again so that I can use the unit?
Many thanks for your help!!
