What did you do in factory settings? What was your BT setting before upgrade in factory settings.

Because you took pictures as advised, didn't you?
[MTCB Software Development] abcdeDE:
Hi everybody, i have the following problem with updating my 4.4.2 to this current version.

On my SD card in GPS slot i have on the root directory the newest update.img (downloaded version 2 from the first page) und the newest mcu.img for my HU.

But after clickin on "update system" in "about machine" i got a few seconds later this failure:

Installation rkimage start

Finding update package

===Update RKIMAGE====

Find and check firmware

E:failed to mount /mnt/external_sd (No such device)

E:cant mount /mnt/external_sd/update.img

Cant found firmware image or invalid image

Installation rkimage aborted

Installation mcucfg start

E:failed to mount /mnt/external_sd (No such device)

Update mcucfg aborted

Installation keycfg start

Same problem with the mcukey ans mcuimg.

At least: update mcuimg aborted.

My current system is:

KGL-V2.55

Android version 4.4.4

rk3188

I will update to KGL 2.83 and Android 5.1.1

Second problem:

If i connect to my wifi 20 seconds later it loses the connection and the wifi icon has zero fields.
[MTCB Software Development] halloj:
Never upgrade the MCU if it works. Put only update.img on the card and try again. I would recommend to use

recover when doing this since you need to clear system+data+dalvik several times maybe.

[MENTION=7056372]abcdeDE[/MENTION] did you read Malaysk's directions on the upgrade. If you didn't already have his FUSE rom, you have to wiped all data.....read the .doc file and do what it says and it should work. I don't know if you can skip the 1st upgrade and go straight to the 2cd one. I did both upgrades in order and no problems. The .doc is within the download for both files

Next step is to check your SD-card. Use 4 or 8 GB. Verify it's formatted with FAT32.

factory Setting code change?

Is factory settings code changed I can not use 126 anymore. I tried going back to the old firmware and was unable to use 126. Is anyone experiencing this issue?
[MTCB Software Development] Oldpapa49:
If I recall, 126 is for changing settings like audio levels, led rgb and boot logos.

I never did an MCU change, but always update.img.

Do you have a reset button that could be recessed and any other button.

Maybe hold reset and start the car?

[MTCB Software Development] Dreadnaughtz:
What's involved in creating a ROM for a MTCB Headunit? Can I pick up a vanilla AOSP ROM (say v6.0) and cook in all the libraries, app, etc using an older ROM (say v4.4.4?)? I'm I missing something big here?
[MTCB Software Development] TT_Vert:
There is another layer of coding that acts as a conduit between the hardware (MCU) and the android OS.
[MTCB Software Development] Dreadnaughtz:
Good point. But the MCU is a separate file to the ROM. Could I use reuse the existing MCU firmware and cook a new ROM based on my logic above? (I assume the MCU firmware could be used on higher versions of Android as long as the API command used are still available)
[MTCB Software Development] ludester:
dude give it a try. I would love to test it out.
[MTCB Software Development] appleknight:
possible to downgrade back to 4.4.4? the 5.1.1 is a bit laggy for me
[MTCB Software Development] germinus:
Just reflash the old rom, you may get a black screen while doing so but that is normal, I would also suggest you flash 4.4 twice just to be sure.
[MTCB Software Development] Dreadnaughtz:
I probably will. Just worried I may brick my head unit as the theory sounds too easy to be true...

This should work fine, although I would recommend using an SSD if possible.

I have a 480GB SSD connected to my Joying unit running the Booroondook ROM (and previously Joying stock) with no issues.

I did use a traditional HDD previously and, while it worked, it was so slow to index my music library (30k tracks) that I moved up to the SSD with much better results.

If you are using it mostly for video (and therefore far fewer files) an HDD should be fine.
[MTCB Software Development] mswguitar:
Anyone else having an issue with Google Maps taking forever to start up with this ROM? Sometimes it take several minutes to come up, especially if I start it from a Directions widget. These worked fine on KK but it's basically unusable on this one.
[MTCB Software Development] THXWOW:
May I ask how precisely you got it to work?

What is your setup like?

Thank you
[MTCB Software Development] jbleasdale:
I have a VW Golf Mk6 + Joying HU + Sandisk 480GB SSD.

The Joying HU has 2 x USB socket cables from the rear which I routed through into the back of my glove box. The SSD is connected to the USB socket at the end of one cable using a cheap USB to SATA adapter. This needed to be a USB2 only adapter as the MTCB devices don't seem to cope with USB3. Once connected this just sits in my glove box.

The SSD is automatically mounted shortly after the HU boots (nothing required to make this work).

I use PowerAmp for my music collection and tell it to index only the SSD. I also configure it not to scan on startup, meaning that the SSD is accessible very shortly after the unit boots.

I take the SSD plus adapter out of the glove box every week or so and sync it with my music collection at home then, once back in the car, tell PowerAmp to perform a rescan, bringing its library up to date.

Works really well - I always wanted to have my full music collection (+cover art) in the car and am really pleased with this setup.

Hello all, i'm new to the android head unit game,

I just bought this

http://xtrons.com/pf75m211a-7-andro...irroring-function-obd2-for-mercedes-benz.html

Which from my understanding is a MTCB RK3188 1024X600

What's the first step for me to take if i don't have recovery ?
[MTCB Software Development] halloj:
How do you know you don't have recovery? I suggest you read the wiki concerning changing ROM before start trying. http://xdaforums.com/wiki/Hui_Fei_Type
[MTCB Software Development] masri1987:
Thanks, I will read that, I assume i don't have a recovery because it's just stock (out of the box just as of today)..

Q: has anyone been able to use viper4android on these units? does it make a difference?
[MTCB Software Development] robbo990:
Recovery is still available on stock.

If it is a first install - just put the image on your gps card - and go to about tablet in settings and choose system updates - it should say it's found an image - then if it's the first time using a Fuse ROM, make sure the clear/wipe all data box is checked. The head unit will auto boot into recovery and install the firmware - when completed you will still be in recovery. Just wipe the data again for good measure (prevents possible boot loops due to partition changes)
[MTCB Software Development] masri1987:
Thanks.

Two more questions.

Is V4A working? or even necessary?

And what happens if i soft brick the HU? Is there a method of recovery ?

Just installed this on a head unit that came with 5.1.1 as stock but seemed not to be possible to root so this fixed that issue. Strangely this rom also runs significantly faster than the stock one that came with it!

I am trying to extract the radio from the stock firmware that came with it with no luck because I am a novice but the new radio app it came with is a huge improvement on the older ones.

The only problem I am left with is that the head unit has adjustable LED buttons which I dont seem to be able to control, is there an app somewhere I am missing or is there a trick I am missing? Any help would be greatly appreciated!

[MTCB Software Development] Jacklad:
You should check Factory Settings (password to get into Factory Settings is usually 126) - make sure that the LED setting is set to RGB -sometimes it will default to one color - if that's the case and you are able to set it to RGB, select Apply and then Exit - the unit will reboot, and you should see a new section in Settings called Elements that will let you customize the button color
[MTCB Software Development] Riith:
Thanks I will look at that when I can, I did go into that menu and fiddle with the setting thinking it might make it appear, it was already set to RGB so I left it alone, I will try toggling it to another and see if that helps. Appreciate the reply!
[MTCB Software Development] Rabidoe:
I have the same problem a few others have listed where my unit boots to the home screen, then after around 10seconds restarts itself again.

Not a big issue except that on the second boot it does not start the apps in my autostart list.

This ROM is a lot slower than the 4.4.4 malaysk mod. I got passed the double spinning, apparently the rom just needed to settle for a few days or so.

I'm interested in trying this ROM in one of the 2 units I have. Both have earlier versions of the Malaysk 4.4 roms from mid 2015. Ideally I wanted to do a backup of the current setup before trying this but when I went into the recovery, I noticed there was no option to backup like I would have been used to with clockwork mod on older android phones. I used online nandroid to do a backup instead, and tried to use recovery to recover that backup rom to make sure it works but it doesn't find anything to recover from. I did run the open nandroid backup to both the GPS and Media SD cards. How would I use the recovery mode to recover to my backup rom??

In comparison with 4.4.4 as if works for responses of applications slightly quicker. But there were problems. The GPS monitor shows satellites (8), but at the same time is written that an error of connection and all of them are red. Respectively in a Navitel it is said too that satellites are connected, but the number of satellites 0 is highlighted yellow (though when you views satellites in a Navitel all of them are visible). Maybe someone had these problems with "a connection error" in GPS and how decided?
