there is someone so kind to make him/it compatible for the version of android 4.4.2 qs kk?
[P3600 ROM Development] Stingray66:
I've a weird thing after flashing to the ROM 0.75 Full of bepe.

After some configuring and installing programs and 2 soft resets, the IMEI number was completely gone (Device information -> indentity). I found out because TomTom didn't recognize my map anymore.

It's not the ROM I think, because after flashing again the number is back to the original IMEI.

Have anyone seen this before?

Note: 99% sure that this has been caused by the McAfee Virusscan Enterprise 8.5i, module Access Protection. When I turn the VirusScan off, the IMEI stays after flashing.
[P3600 ROM Development] T-Rob:
which programs did you install, I also use bepe 0.75, no problems so far.
[P3600 ROM Development] dnts:
This happens to me every other soft reset

IMEI and device serial number both turn blank. Installed and registered programs (like hebre support) go into inactive mode due to registration failue. So I soft reset again and again until it works (2-3 time in average).

I use Indigo full but I guess it's common to all WM6 and has to do with some marginal timing issues with the hardware, coupled with some new firmware (WM6) that reads the data from flash too soon.
[P3600 ROM Development] hcarrega:
same happens to me in pdaviet rom but with bepe works fine
[P3600 ROM Development] Stingray66:

Hallo stingray,

your TomTom original traffic works on this bepe Rom?

Greats Remo
[P3600 ROM Development] dnts:
Hmmm.... How does McAfee have anything to do with IMEI? I had this problem but have Trend AV SW on my PC....
[P3600 ROM Development] sickboy555:
Stingray,

are you sure it's McAfee?

I'm also using McAfee Virusscan Enterprise 8.5i with Access Protection (I had the Traffics Subscription issues)

Could this be causing the Device ID to change with some ROMS? IMEI is one of the things used to generate device ID isn't it?

This has got to be too coincidental to be ignored....but then again I flashed my phone about 3 times the other night, and thinking about it, it was on my laptop with no Mcafee OAS......Only mUn TE keeps working TT device ID
[Galaxy S5 Mini Q&A, Help & Troubleshooting] Morthawt:
edit: My phone is the SM-G800F

So I bought an S5 mini from ebay and verified it was all legit, legit packaging, tested via apps that check everything etc. Everything was saying all legitimate. It was defaulted to German region DBT. I thought everything was fine since during install I had set the phone up as UK English until it came to rebooting after encryption when the keyboard was not standard QWERTY, it was specifically German and since my password is more about pressing of certain on screen keys rather than the info being typed I could not get at my data. Well I downloaded the latest H3G firmware so that it should be in UK English on my own network most likely (My sim's network is 3)

This is what Odin shows:

Now, the only difference this time, compared to flashing my S4 mini as I have done lots of times, is when I extracted the zip file for the firmware, 7zip complained about extra data after the payload... I updated to the latest 7zip and so I am not sure what's going on but Odin did not complain about any md5 hash breakage so that should have been fine. Also it came from a different site than I usually get. I got the firmware from two places and it seems the same, no hash breakage. I am downloading one now from sammobile which I think is where I got my S4 mini firmwares from.

Can you think of anything that would make this happen and what I could do to fix it? I tried Kies 3 but it just doesn't work, says something like no compatible devices and then when I try and do the emergency firmware recovery, the device does not show up in the list to even attempt anything.

I would appreciate some guidance on this.
[Galaxy S5 Mini Q&A, Help & Troubleshooting] Morthawt:
Ok, I flashed the original German firmware and it is siccessful and wants me to set it up again as brand new BUT I need to flash the English firmware.

Is there any way I can flash my UK firmware (H3G) on this German S5 mini? Any extra options I need to select on Odin?

Have a look at this https://www.reddit.com/r/Android/comments/323l36/android_5x_how_to_disable_guest_additional_user/

Make sure you have backup of files you edit, it's very easy to **** up when manually editing files

edit: lol just noticed xda censors swear words, this reminds me that i have seen a setting in maybe gravitybox or some app where u can remove add use or switch guest from notification bar on top, which is probbaly what you want to do, i will check around and see where i found it.

EDIT: Another thing I just tried and it works well

Add the following lines to your build.prop

fw.max_users=1

fw.show_multiuserui=0

Change the max users number to however many users you have on phone now. I did the database change earlier too, and after adding these two lines there's still icon on lock screen to switch users but it doesn't do anything, i got a long loading the first reboot, but that maybe because i am also playing around with xposed modules, just force reset the phone by pressing volup and power for 3 seconds and it should boot. Hope this helps.
[Xperia Z3 Q&A, Help & Troubleshooting] ataraxist:
I read it. Did as said. Added fw.max_users=1 but did not add fw show... The phone went into boot loop...

[MTCB Hardware Development] LC4T:
Hello everyone,

I have a Erisin S2046B in my 2001 BMW E46 and found information, that the RK3188 has several external buses which are partly currently not used in the device. Being an electrical engineer and having some projects in my mind which require some sort of external communication to e.g. microcontrollers, I would like to make use of them.

Did anyone go through the effort to use one of these interfaces?

I read in the sound processor thread (http://xdaforums.com/android-auto/m.../mtc-sound-controlling-bd37xxx-sound-t3234660), that I2C is used there but only limited information on what is done exactly, as it is just a matter of reconnecting the bus lines from the mcu to the rk3188.

I'm not quite sure, if this is the right section, but I would not really consider this "software development". Anyway, if one finds it inappropriate, I would kindly ask a mod to move it to another section ;)
[MTCB Hardware Development] dgcruzing:
This is great, hopefully it's with guys like yourself tinkering away at these devices we end up with a how new sub-section of interesting mods that can be done for those that like to take stock and improve on it..

Bookmarked for reading as you go through this ... Look forward to some.positive outcomes...
[MTCB Hardware Development] 7floor:
[MENTION=7106563]LC4T[/MENTION], can you be more clear as to what do you plan to achieve? It is no problem to attach another slave (or more) to existing I2C bus, as this bus is a multi-slave in its nature. There's no need to find any interfaces not in use, you are free to use existing, well known one.
[MTCB Hardware Development] LC4T:
As I already mentioned in my posting, I personally plan to connect an external microcontroller and exchange data between the µC and the RK3188. As I don't want to fit the circuitry inside the erisin enclosure, I2C is not the preferable solution.

The principle of I2C and its architecture is known to me, I have already build hardware using I2C ;) But as the existing I2C bus is already connected to at least one slave device, I would be careful with hooking up another one without knowing exactly, what's happening on the bus already. Worst case would be to make the whole existing system unstable. I'd rather use SPI oder UART for my purpose.

In general, this thread should not be seen limited to my intentional use but some sort of collection of information on which buses are present, usable and in use - knowledge base style, so to speak :)
[MTCB Hardware Development] pounce:
What's the first solution that comes to your mind when you think of doing something interesting with your I2C?

Some of these units do CANBUS. I'm not sure if there is separate hardware in them or just hookups.
[MTCB Hardware Development] LC4T:
I plan on installing an engine block heater (webasto thermo top c). With the universal wiring kit and control unit, you're only able to set three starting times with a fixed heating time. Additional control units for remote control are quite limited in range and functionality, the "cheap ones" (~200€) only offer "start" and "stop" with the only feedback if the command reached the unit being a blinking led, the ones with the ability to set the starting time from the distance (they claim it works up to 1km depending on the building density) is 350€... There are also GSM units available but also quite expensive and with few functions.

So including a microcontroller would fix all that ;)

If I got it right, the CAN unit is a standalone device, that only decodes relevant data (e.g. gearbox in reverse), so no communication with the android device itself ;)
[MTCB Hardware Development] pounce:
I believe there are can bus controllers for that device.

You could take a look at IOIO-OTG boards. it might offer some features.

You can make your own can bus for the devices you want to control and use available can bus adapters.
[MTCB Hardware Development] LC4T:
If you're talking about the webasto heater, yes, there are control units with CAN functionality but they are OEM specific (e.g. VW/Audi, Mercedes, BMW,...) and not universal. Also, adding just another interface is not what I intended to do when there are several of them, mostly unused already available ;)

Again: I don't want to use this thread for my specific problem but as a general thread on using the interfaces already present in the unit :)
[MTCB Hardware Development] pounce:
Sure. Sure. I like the idea of tapping into the onboard hardware, but it might be good to talk about the limitations and optimal use cases for doing so.

For your case I think you can solve your need without tapping in if the objective is to get it working quickly. If the geek factor is more important then its a moot point.

You could probably tap in using something like this:

sandboxelectronics.com/?product=active-i2c-long-cable-extender-p82b715-module

That might help cut down on noise if you want to run it around the car.
[MTCB Hardware Development] 7floor:
Here's my thoughts.

If you need to control some external DIY device, you need to go with USB ports, which are already available in our devices.

They are just designed to communicate with external world, opposite to I2C or SPI, which are designed for in-system communications only.

Here we have two options:

1. Use native USB communication:

On the headunit side - libusb library which is well-known in Linux world. It might even happen that it is already compiled into the kernel (need to check); otherwise, a libusb.ko module needs to be compiled and loaded.

Nowadays there are many microcontrollers with USB onboard for direct use; and even simpliest MCUs like AVR attiny/atmega can use USB via V-USB library (I've done some just-for-fun projects with it).

2. Use a cheap USB-Serial converter to get a new serial port on a headunit's side. On the MCU side, you'll get a standard UART, which is much simplier than USB for MCU programming.

And returning to your [MENTION=7106563]LC4T[/MENTION] idea.

Are you planning to use head unit only as a control panel for your device, so that you only need a big touch screen with a nice UI to set up your externa DIY device, then go off letting that device to work alone? Don't you plan having your head unit always turned on to track time and on/off your heater? Because latter solution is really bad, as our head units are very power hungry.

The IOIO OTG solution gets you here plus there are established libraries etc.

The OTG version allows it to be powered from the host also. That could make it easy to develop and move around.

[MTCB Hardware Development] 7floor:
From $20 for the board on AliExpress to almost $40 elsewhere? No, thanks :) These guys want too much for their solution. This is the price of a Raspberry PI, a complete computer.

For that price, I would prefer putting a Raspberry under dashboard, connect with WiFi, for example, and have much more flexibility than gives the IOIO.

As to IOIO - as a prototyping board it might be useful, but not for a well-finished DIY project based on a single cheap MCU with a minimum of components, where total cost of it would be much lower than cost of that board.

It is like using ATmega256-based Arduino boards for the purpose of watching a button and blinking a LED, where the $0.5 worth ATtiny13 is an overhead.

Such a boards are probably good for Hackaton events, where you have to show something working after a few hours of quick-and-dirty work, but not for thoroughly designed DIY project.
[MTCB Hardware Development] pounce:
Depends on how much you value your time and what an existing product offers you for your solution. Many people aren't as price sensitive. I certainly wasn't suggesting the IOIO as the only solution, but for an open ended or more generic solution to get hardware support external to the head unit is generally fits the bill. Established libs for interacting saves some time. Nice bunch of people put it together and there have been some fun projects.

Like I mentioned before, it might be a good idea to discuss what the objective would be to adding smart hardware in the solution through, I2C, USB, bluetooth, wifi or whatever. I think the OP is looking to discuss the general idea and not super specific solutions that might lead a person to pic a very specific ic and com. Well, I know that was the purpose because the OP has redirected me to the point.

You bring up a good point though. You say you would rather put Pi under the dash. I would also for controlling things. In fact Pi or some duino realtime solution is always going to be better for interacting with an auto. This is especially the case when the purpose might be controlling something that is powered like a motor or something life critical. At this point though we are not talking about android or these head units. You are talking about perhaps the method of communication between two systems. Not really for this forum.

---------- Post added at 01:05 PM ---------- Previous post was at 12:46 PM ----------

I'd like to have more input/output trigger wires for events. We have a backup wire, but I'd like more for other things. An example might be to support a passenger side view camera. Sure, there are ways to hack it in by switching the backup video input, but that's a simple example. Power on a wire sends an event in android on the unit.

Do we have GPIO possibility on any of these units?
[MTCB Hardware Development] dschiesu:
CanBus via Uart?

Does anyone know how the CanBus connection works? My MTCB Unit came with an adapter box which turns some messages into external signals (like illumination, reverse), but also seems to forward messages via serial into my Head Unit. At least that's how i guess that the steering wheel buttons are working.

Now, there are some messages that i wish to interpret and send, and also some i would interpret different. My idea was to get some kind of filter (maybe software, maybe a dedicated micro controller) in between the CanBus adapter and the service on my head unit. But right now, i have no idea how to verify my understanding of the setup, since no tty device on the HU seems to directly reflect my button presses. There's one, that pours out something unreadable on key press, but this also does it if i touch the screen, so i guess that's not the CanBus adapter itself.

I suspect that the information in already interpret before it gets into the android system, and only the relevant messages are forwarded, or even pre-processed. I suspect that the only way to get to the signals is to listen on the CanBus adapters RX/TX lines, and maybe finally put an microcontroller in between. If unlucky, the adapter might also filter out messages before i can get them, and i need to access the CanBus directly.

htt p://i.imgur.com/P1QzXta.jpg?1 << CanBus Adapter

I would appreciate any hints on this topic, especially information on the CanBus Adapter.
[MTCB Hardware Development] LC4T:
From what I can see on the PCB and I have read about the can adapter:

The adapter itself only interprets data from either can bus or analog signals and forwards them to the android unit via some sort of serial interface, most probably UART. As you have almost no way to get an inside look into the software running on the microcontroller, I would suggest to design a seperate device, that way you can be 100% sure to get all the messages and filter yourself.
[MTCB Hardware Development] dschiesu:
I ordered some can bus adapters to see what i can read. Maybe i will first have a look into the data on the serial line when i finished moving house and had time to unpack my gear :)
[MTCB Hardware Development] esteves13:
I have a can bus HU, when i listen to the radio or music player, i haven't information on display of my car (CLK MERCEDES). I read the new units have dual can bus and information of radio appears on car display. Ther's a way to modify my HU to dual can bus? I have to change a can bus decoder? My can bus decoder is B200.

Regards
[MTCB Hardware Development] oskaratk:
Well known interfaces - that's the keyword.

For example I would like to output current FM-frequency, radio station name, song title to the existing (factory) FIS display in a car. Via CAN bus, because the display talks CAN.

Now I would at least have to know which units have CAN capability.

Yes, I could go the USB to RS232 to CAN dasy-chain-adapter route, but I consider that all but a clean solution
