Yes there is a image for 4.4 for rk30s. In pretty much any combination of bluetooths or wifis. More popping up everyday.

You would have to copy back all of the add ins and stock system apps. God only knows what would not work. Only one way to find out. To brick or not too brick that is the question.

You could only flash it via flash tool. I think it would go in there though. As long as you do not flash the recovery, You could always just go change it back.

These are after all chinese 7" tablet with a serial link to a mcu. They changed the screen and the touch panel, but that seems mostly handled by the mcu app and its imported software anyways. It seems most everything is added on top of the normal 3066 base tablet rom. I would leave the kernel it has 36+ on it so it will run 4.4

If you got the gonads or the cleavage, I will post a link to the expanded rom.

I was sitting here thinking about it if you did not overwrite oem it would still be there so the default crap would still come up....this may work...more than likely not though.

I may go overwrite boot misc and system and see what happens.

I will wait until my 4.4 sample shows up to really f with this thing, just incase.

hi ive rooted my device, and installed xposedMTC, when launching it allows me to select poweramp as the default music app from the drop down menu, however when reboorting the unit the stock music app is still the default when i either toggle through mode\sterring control or when using the stock music icon

also is there a write up on the SWC, as still not working. think ive missed a step

I contacted my seller before about my issue with FW upgrade, but somehow they are under impression that I am still not able to upgrade my unit, I told them twice it is working now but now they just send me FW 2.01 with MCU KGL4 2.01.

http://en.mail.qq.com/cgi-bin/ftnEx...4c4850136104&t=exs_ftn_download&code=eeb29ca9

Was there even a FW 2.01 since I don't see it in the file repository?
[MTCB Android Head Units Q&A] ptclabs:
yeah they are shipping new units with it

The sample I got from kai last week had 2.01 normal in a universal unit on it if there is a need for i can ask them for it. I thought there was newer firmware out though?

If you need it just let me know I will get it from them. It is not like they try to hide it...
[MTCB Android Head Units Q&A] xrapidx:
I wouldn't mind the straight KGL version ... so I don't have to hassle with loading different things.

I think the latest is v2.03.
[MTCB Android Head Units Q&A] zorantoma:
Did you try the 2.0.1 update? Meybe thic MCU is now working as it should for our vw units.

Mtcb-gs-v1.91

I have my Huifei 4.2.2 with the operating system from https://drive.google.com/folderview...&usp=sharing&tid=0BxmzvLRI7-eNeVA2SWkwM1pLZ28 with the version number V_2.03_KGL_ (20140903).

The firmware does not show any obvious changes. Everything looks like before the update.

All programs start without causing error messages.

Hope to be able to help with this information.

The MCU.img I have not installed. My MCU has the MTCB GS V1.91 firmware and as I had read previously, I may well not have the GS version with another version (KGL etc.)

Sorry for my bad english.
[MTCB Android Head Units Q&A] agentdr8:
Did you also install the Xposed Framework? That has to be installed, and then the app_process has to be enabled.

Also, the stock music icon will always launch the stock music player. In the later versions of XposedMTC, I added additional launchers for the preferred apps named MyMusic, MyVideos, and MyRadio.
[MTCB Android Head Units Q&A] Reptile-X:
Ah okay, that explains it, I don't have MFSW, it is one of my future projects to retro fit a MFSW. So the 1.77 MCU is perfect one for me right now.

Sorry I couldn't test 2.01 for you :(
[MTCB Android Head Units Q&A] xrapidx:
How would you go about installing the Klyde firmware on Huifei?

I might try that on the weekend if I have time for a full rebuild.

No problem. Now that i know that i can flash a MCU seperatly it's 10min work,so i will try your MCU in the wikend.

Done that and it works perfect :) No problems at all. Just don't flash the klyde MCU and you're god to go

How to get sound output with BOSE ?

Hi,

I have just received my new head unit Erisin ES9784GE: http://www.ebay.de/itm/ES9784GE-7-Android-4-2-2-DVD-GPS-Autoradio-AUDI-A4-S4-RS4-8E-8F-B9-B7-SEAT-EXEO-/231279316444?ssPageName=VIP:watchlink:top:de&fromMakeTrack=true

I installed it today and it seems to work well except that I do not get any sound at all.

I guess I need an adapter to use it with BOSE right?

I did search the forum but could not find any hints on how to install the unit with BOSE.

I have a SEAT Exeo form 2011 which is identical to the AUDI A4 from 2008.

Another question is what would be the best firmware to install. The unit came with version 1.95.

Any help is highly appreciated.

Hey guys, how can i turn off the unit by keys or apps? My unit won't power down when the keys leave the ignition. If can't find a way then my battery will be dead by morning !! Btw I don't have root. Any help is greatly appreciated!!
[MTCB Android Head Units Q&A] agentdr8:
Sounds like your ACC (red) wire isn't connected correctly. It should sense when your key is removed from the ignition, initiating the shutdown procedure.

I have wifi issues, sometimes i have disconnections and when i disable the wifi it isn´t possible to reactivate it. only a reboot helps. i use the 2.03 kgl Version with 1.91 gs mcu. but i think it worked at the beginning. can the Installation of xposed framework be the reason?

thanks and sorry for my english :good:
[MTCB Android Head Units Q&A] agentdr8:
Most likely the kernel. Some people experienced this issue when using kernels newer than the one provided in the 1.77 system update. I would recommend flashing that kernel and see if it resolves it. Search the thread for kernel and flash_image and you should find some posts on how to go about it.

No, MCU it self is around 40kb and the kernel is almost 8mb, read this here:

Partly successfull :good:

I found out that connecting the cinch speaker wires with each other works.

However now I am getting more noise than I would expect. :crying:

There is obviously a ground loop which sounds really bad.

I read here in the forum about an adapter which can be ordered at amazon in the US but I would rather order one here in Germany.

Does anybody know an adapter which is available in Germany and which is working with BOSE?

I must correct myself concerning the firmware version. I have version 1.93 (not 1.95).

Thx,

I have Bose in a Chevy suburban, 2003. My adapter is the PAC OS-1. I know they make adapters for other cars. I also have the axiss (I think 4) to retain come and steering wheel control.
[MTCB Android Head Units Q&A] ptclabs:

reboot -p

but i do not know if it will shut down the mcu

Also it is immediate if it is doing anything to the file system it can cause errors.

I found one bad thing about KDL firmware. It will only auto-connect to one phone.

Can someone upload a bluetooth.apk app from KGL and get me a link please?

I am starting the buddy up process with RM. Will take some time though. They are a large company. Does anyone have their firmware? I have not seen it posted anywhere. Well nothing past 1.86
[MTCB Android Head Units Q&A] artaxcc:
No the wires and stuff are connected correctly. But I think a background service crashed so that it didn't initiate a shutdown process when the key left the ignition. I think it's this because the keys on the unit didn't respond as well.

I better root the device and install a manual shutdown app :)

Sorry for off-topic, but did anyone use a small usb cam for dash-cam ?

If so, which one did you use and how good/bad is the quality ?

I would like to record the in-front traffic as you usualy do with a dashcam, but i dont want a huge cam.

The plan is to mount the cam somewhere out of my field of view and undetectable for cars in front of me.

Parking sensor display delayed

Hi,

Thanks for this awesome forum it helpt me a lor with sorting out a bunch of little problems.

How ever there are 2 little issues I keep havin.

● The backup sensor image is very late with showing the distance markers. The beeps from the car work fine but the visual guidance doesn't start till i basically ran through the wall already.

●the other thing is that i keep getting 3 times an input for 1 button press on the SWC.

Could anyone help me with that?

Im am running FW and MCU 2.03 and have a Erisin ES9401A

Thanks.
[MTCB Android Head Units Q&A] Warlord711:
Thats a known bug and i havent seen a working solution yet.
[MTCB Android Head Units Q&A] nexgen10:
Has anyone else had any problems with quality? Of the 5 units we got, 3 were sold and 2 were kept for testing. The first testing unit developed a hard lock condition after a few months of operation and was replaced with the second test unit. The second unit worked fine for months before the amplifier/audio went bad and started losing volume and developed a screeching sound. The bottom of the unit got hot enough to burn your fingers within a few minutes of powering on.

I took the large PCB out of the first unit and put it into the unit with the sound problems and the problem appears to be resolved. Has anyone else had any such problems? We were planning on buying many of these units for sale in the US, but are reluctant to move forward with these plans because of the quality concerns.

I'd read the thread, but its grown considerably since I last looked at it (Page 75)!
[MTCB Android Head Units Q&A] agentdr8:
The service responsible for shutdown at key-out conditions is MTCManager, and if that's crashing, then there's something else wrong. I would recommend a factory reset or flash one of the newer system images.

You can also press & hold the volume knob (if you have one) and it should initiate shutdown. Once the screen goes dark, then press the recessed reset button, which will cut power to the MCU. If you don't press the volume knob, it should stay in an off state.
[MTCB Android Head Units Q&A] typos1:
Which units are you talking about ? - The HuiFei/KGL ones, the Klyde ones, the RoadMaster ones, or the "GS" ones ?

The HuiiFei/KGL have been reported to blow speakers on occasion, have poor radio reception on occasion (this seems to be down to aerials not being connected to the radio IC internally) have poor sound levels and poor microphones.

Flashing the Klyde firmware onto them (but NOT the Klyde MCU) has reportedly sorted out any microphone and sound level problems.
[MTCB Android Head Units Q&A] nexgen10:
HuiiFei/KGL models.
[MTCB Android Head Units Q&A] bpalmer1455:
I'm new to this.

First thanks for all the great info. I have tried to read through most of this thread -- but it is a monster. Also really tough to get through for someone that isn't familiar with much of what is being said.

Here's my situation. I recently purchased a 2005 Ford Escape Hybrid for my daughter to drive to and from school. Well, the car is 9 years old and the only means for playing music is the radio and a 6-disc cd changer under the seat. Since she is a teenager, she would really love to have more options and i don't blame her. She has never even owned a cd!

Next thing is that being a hybrid the stock stereo/nav screen displays more information than usual. Hybrid battery state of charge, instant MPG, average MPG and so on. That leads me to this thread. I am considering installing one of these head units (or something similar) with the intent of running Torque Pro to monitor the hybrid functions and also allow more options for listening to music.

So I really only need a unit that can run Torque and play music. No steering wheel controls, back up cameras, other cameras, no games, no videos, no other apps besides maybe pandora or something similar. It can include those things but i don't need them. The kicker is that it needs to be pretty reliable, pretty simple to run and I really need to keep it under $350.

Can anyone advise me?

Thanks,

Brett

MCU 1.86

does anyone know if the 1.86MCU has problems with button lights being always on and GPs button set as back button for vw models? I'w searched the thread but didn't find what i was looking for.
[MTCB Android Head Units Q&A] Reptile-X:
You already test it yourself zorantoma on page 145. Maybe you forgot it after that many tries and after 2 months :)
[MTCB Android Head Units Q&A] typos1:
Right, well I pretty much gave you the answer in my previous post - I ve tried to refrain from saying any one unit is better than any other in the past, but based on the number of reports of problems with the KGL ones, I m starting to form the opinion that its best to avoid them and buy either RoadMaster or Klyde versions. The GS models are supposedly the same internally as the Klyde ones according to the published specs, but no one has taken one apart to check, I think I do remember someone saying the MCU was the same as the KGLs, which would mean the published specs are wrong as the Klydes have different MCUs. A few people have put Klyde firmware (NOT MCU though) on KGLs and report improvements, as I said before, whether or not the Klyde firmware would prevent the problems youve had or not is unknown, but you could try it and test further.

So, unless someone else chimes in and/or agrees/dis-agrees with what I ve said, you either have to take my word for it, or read the entire thread tallying how many people have problems with each version and base your conclusions on that, which would probably be more accurate. Unless, of course people only come to the thread when they have a problem, which could mean doing that would be less accurate, as in theory there may be more people out there without problems with KGL units but we dont know because they havent posted as they are entirely happy with their unit. :eek:

RM firmware on GS and KGL

It works.

Has same bluetooth problem as the KDL. Really cool looking over complicated launcher. I think my wife might like it though.

On the GS google understood me almost perfectly. (I think they turned up the mike volume) KGL was about the same.

AMAZINGLY the rom was set to Urdu by whoever programmed it. Gee I guess those chinese programmers are looking a little more indian after all. I think the chinese "programmers" are just changing and hacking into rm firmware. More or less what we are trying to do and often failing. I am wondering if the programmer are the 2 indian guys with pictures all over the RM site. Someone needs to become their friend.

Either way seems stable, but still the BT problem might send me back to HF firmware if I cannot find a solution.

I will try beating up on rm, but they are huge company that might not care.

Does anyone think the fobo tpms will work with these units. It is slated for a November release date. I think it requires at least android 4.3 though. Thoughts?
[MTCB Android Head Units Q&A] typos1:
I think the reason the RM files so much bigger is because of the very feature laden launchers.

Could you not compare the BT apps from the KGL versions and find out what makes it work better with multi users, then add those lines of code to the KLD/RM BT apps ?

Saif Barry, months ago posted a RM review on youtube ( http://www.youtube.com/watch?v=OjVGFoaSXNU&hd=1 ) and he could install other launchers but not use them, do you have that problem ?

That is a AN-21U unit discussed at http://xdaforums.com/showthread.php?t=2528349

About your other question about really identifying units before you buy - have the seller send you the image of the android about screen with the MCU firmware version. That should really tell you if you have the KGL/KDL/RM/GS units - as the faceplates are all common and backs can be confusing.

Pumpkin HuiFei

Hello,

I just recently purchased this - http://www.amazon.com/gp/product/B0...tailpage_o04_s01?ie=UTF8&psc=1#productDetails

A couple of notes:

1. It appears to be another HuiFei model - specs all align with what is said in this thread (including the Developer password).

2. MCU says MTCB-GS-V1.91

3. I am having a real hard time having my ELM327 connect - scanning for new Bluetooth devices yields nothing.

4. There is no "Extra Settings" - so not sure where I go to map the physical buttons (I want the Navi button to map to Google Maps).

Other than that, seems to be working nicely.
[MTCB Android Head Units Q&A] typos1:
Its a GS version, very similar to HuiFei/KGL, personally, I d recommend USB to OBD rather than BT to OBD connection.
[MTCB Android Head Units Q&A] dwmcqueen:
Yeah - that is what I just figured.

Now, the manufacturer says it is one LED, but the settings say it is RGB....Orange LEDs and the external button remap, and I'd be 100% happy :)
