Full AOSP on MStar Cedric3 head unit - Android Head-Units

Hi!
I bought it on eBay one head unit with the following originals characteristics:
CPU: Cortex A9 Dual-Core 1Ghz
GPU: Mali 400
RAM: 1GB DDR3
Android Version: 4.4 (but really is 4.2)
MCU original Version: 4.3.11-1-03-615101-150112
System Version: 2.9.5_20150413
Anyway, I tried to update the MCU with the head unit who brought extra settings -> model choose, but the upgrade to 4.3.13 everything works fine except the lights that indicate the volume level, and that is not moved up or down the volume.
I suppose that changing the MCU has stopped working. How could recover the original MCU?
I contacted the seller, but no longer sold items on eBay and I doubt I answer.
Thanks in advance!!

Hi ,
There is a setting that could rectify your problem. You had the setting open on your 2nd picture (model choose).
You probably have to try several models to see if one will work for you. Each time you choose one the unit will set the parameters then reboot ... do not interupt this.
After it reboots try your various controls to see what has changed.
My unit is the 2 knob version AN21-U. When i installed the RED MOD firmware my volume knobs were non functional. After trying several models from the "Model choose" screen in the extra settings menu it corrected my problem.
Hope this helps.

Hi.
I have not been lucky.
The seller gave me the original MCU, but when I try to put it through a USB not done properly.
If I add to the list that is in the internal memory, it does not appear to select .

Hello all, I'm looking for the updated MCU files and android updates if possible.
Does anyone have a link to the files please please!
Thanks

Hi All,
Does anyone know the code to get into the developer options for this android head unit?

Many thanks to Allen Wong from http://www.carnaviplayer.com/ for those firmwares!
Can you provide a link to the S150 specs and purchase?
Thanks

Can i make a mirror on the File on a other Server?

Far too curious. Far too cowardly.
Heh. Still too chicken to try it myself.
Couple of questions :
1) What doesn't work (that you know of) ?
2) Is the TV-Tuner software present ? Are all Video inputs available and working ?
3) rooting/framaroot still working ?
It would be great to see a small video of a brave soul who's flashed his S150 with this firmware, just to see how it acts (boot time ? Radio App ? Is the hidden BT menu still present ? Stability issues -bound to be there in a Beta release- ?)
Thanks for sharing this !

1) One thing is not working correctly is color button chooser. It selects everytime Orange.
2) Tv tuner is working (my unit has dvb-t)
3) Not tried yet, however I doubt it will work.
I flashed back original firmware because i don't like unfinished things
However this new firmware is very usable.
Can you give me a howto install the Rom?

Thank you, I will download the firmware and probably I will try. It could be useful to have a step-by-step procedure to install this SW and, in case of problem, roll back to the original one.

Any way to download this WITHOUT using their download manager ? I never install any proprietary managers, don't trust them, and this site does not seem to offer an option. Can somebody more adventurous make a copy on another site ? I can fire a Virtual Machine, I know, but maybe somebody already did it.Thanks.
I will upload it today in a other mirror.

Agreed.
While the steps in the previous recovery weren't really rocket science, a fully discribed step-by-step would be a usefull addition to many of us.
And a rundown on this versions' behaviour in terms of boot time, working speed and stability, rootability .... too. For example, did anything change in terms of behaviour in Play Store ? Added compatibility with other Navi software which gave sound problems under 2.3 ?
But also a bit more out of the box : For example, I needed the Root to enable Adhoc. I know Adhoc is pretty much broken in 2.3, but I thought it's fixed starting 4.x. Another example : Torque supports USB OBD2 interfaces starting Android3.x . So it should work under this 4.x too, no ?
So many questions. :laugh: Exiting times ahead, I think.
Can someone link me to a place that sells this unit? Ive tried ebay and aliexpress but dont know which one I should be looking at.

Hi guys,
as promised i'm starting a new thread on S150 Android Head Unit.
This first post contains a new OS beta release based on android 4.0.3 I found somewhere
Keep in mind this is a beta release and it's not yet 100% complete.
However most funcionalities are OK and it's usable.
You can come back to original firmware simply using the previus package i posted on

Do you need a standard "2DIN" unit or a kit for a specific car ? I bought my unit (kit for SantaFe 2013) from this seller: http://stores.ebay.ca/ULikeShop?_trksid=p2047675.l2563 ; They have now kits for many different car types (and a standard 2 DIN).They shipped really fast the unit arrived in 5 days.
If yoor car is old and just needs a standard 2DIN, this is it: http://www.ebay.ca/itm/6-2-Android-...Video_In_Dash_Units_w_GPS&hash=item4d0d88e507
If your car is newer and you can find it on the list better get a kit, it will include the proper faceplate, cable harness (so you don't need to cut cables) and the CANBUS adapter so you can use steering wheel controls from your car. I recommend to find and order a proper rearview camera, the unit has the inputs but does not come with a camera. There are many on eBay look for one which can easy mount (again you may find one which mounts on your car for example on the bulb place of your license plate ) or some general one. Get a CCD one they are better than CMOS ones. Any rearview camera will work, as standard composite video signal is used (goes directly to the LCD not through OS).
This unit also support a front DVR camera, but to be able to use it with the unit software you need to get the one they specify, there is only one Front DVR camera supported, is this one: http://www.ebay.ca/itm/Car-DVR-Came...899?pt=LH_DefaultDomain_0&hash=item3f28b5d543 available on eBay or aliexpress from different sellers (I don't use one, but may be useful).
I attached also a few pictures with different screens, if it looks like any in picture (and has a Samsung SoC) is most likely an S150.On this seller at least, look for the units with the "Orbitz" screen (attached) these are all S150. Other sellers may show other screens, the one with the clock is the main screen. If you see other main screens (more standard Android look) they probably are other models, not the one discussed here.
Manual and install diagram
For the ones which do not have the unit but are thinking to buy one, I attached the manuals and install diagram.

Manufacturer (hidden) settings
Good to remember. There is a hidden menu where you can set a few things, like the Radio region. Most important for me (thanks kaween) was to set the CANBUS type. Without it steering wheel controls did not work, even if I had a car kit. You go in there:
go to BT (phone) dialer and dial #*98723 + call.
For me I had to select the second available bus type from the list. Probably the default setting (first one) means disabled (I don't read Chinese, somebody who reads, may confirm). As the list is long you may need another bus type, depending of your car. This will work if you have a "kit" unit , for the standard 2DIN one you don't have a CANBUS adapter so will not work. After a factory default reset or a firmware update the settings go back to default (first selection for bus type and Europe for Radio). There are a few other settings available, if anybody plays with them please post. These settings or the way to get to them are not described in the manual.
If anybody plays with newer, beta firmware please check that the code is unchanged and you can still access these settings.

The device (at least original firmware) can be rooted with Framaroot ( http://forum.xda-developers.com/showthread.php?t=2130276 ). After root install BusyBox from market also as many programs with root access require it. If somebody installed the 4.0 beta, try and see if Framaroot still works (or they closed the vulnerability used).
Bootloop?
Hello!
My S150 won't start up anymore. It's stuck in some kind of bootloop. I don't know what happened. It stops at the "Android" logo. But when I turn the volume knob or the volume on the steering wheel control the status bar drops down and shows the volume change. Is there a way to restore the unit? Pushing the reset button doesn't help. I have read the instructions for the bootloader installation using Linux but that is way to complicated for me I think.
Please help!

Need some Information about similar RSNav S3 Devices

Hello everyone!
Ive bought a RSNav S3 Head Unit System for my Audi A4 B8 2010.
Im trying to find out a few things of the device to root it and cusomize some things in the system. (Root, TWRP, Key mapping, MCU modification)
Do you know a device which is similar to the S3 Board i have? It could be that the Devices uses the same Software and MCU as other devices. I found some Strings in the System APKs where other Car brands pop up.
I have the complete Firmware of the Device (no source) and an update File for the MCU (.mce).
Here are some Specs:
Qualcomm MSM8953/Snapdragon 450
4Gigs Ram
64Gigs Rom
10.25Inch Screen 1920x780p
No Hardware Keys (except hidden Reset Button)
No ADB USB Port (someone said that its hidden in the case)
https://rsnav.com/collections/s3-an...system-for-audi-b8-a4-s4-rs4-a5-s5-rs5-q5-sq5
I've attached some Images of the UI
Maybe somebody can help me
So I found out something of the device.
There's a Quectel Sc600y build in. Also there's a pinout four a debugging usb port. But when I connect a USB Cabel to it, windows says that the device is faulty and can not be detected.
Must it be enabled in firmware? Can someone help me pls
Hi.
Any news? Will receive my S3 unit soon too.
No, nothing found yet.
I've done some research in this. Most of the Apps Uses Programm Parts called "com.mct" or "com.hc". But i didnt find somting about that on google.
I've seen launchers which look pretty similar to the S2/S3 launcher of RSNav. But dont found someting about them too.
Also Magisk is not available for that atm.
So i was able to root the S3 Device.
I will create a script/guide soon.
Found out that the MCU must be integrated in the System under /dev/ttyHSL2. But atm im unable to read messages from it. Baudrate is set right, but i only get cryptic messages.
Maybe someone has an idea how to read it right.
Hi mate, I'm interested if you can share how you rooted your S3 unit. I will receive mine soon and I would like also to root it. ty

So i was able to root the S3 Device.
I will create a script/guide soon.
Found out that the MCU must be integrated in the System under /dev/ttyHSL2. But atm im unable to read messages from it. Baudrate is set right, but i only get cryptic messages.
Maybe someone has an idea how to read it right.

Problem with head unit - google play account crasches and GPS works not good

Hi everyone,
I 'm new heer and i hope i can find some help with my head unit.
Sinds few months had problems with my gps signal - after 15-20 min driving signal is gone and then back again after a while.
I bought new gps antenna and wanted to update my navigation app but when i try to log in to google play it crashes.
I couldn't find any stickers on the unit so i don't know the brand.
these are my specs:
Android Version:

Hardware information:
4-Core AllWinner-ROM 32GB - DDR3 2GB - 1024x600 - cq1

MCU Version:

Wil someone help me with identifying my head unit and maybe providing a good rom/mcu update. I tought about rooting it also.

Hi Guys,
Is there really anyone who can help me with my problem?
I've serached in forum and found this one:
Bugs and updating firmware - 4-Core AllWinner ROM 32GB - DDR3 2GB - 1024X600
Hey, i would like to know if there is any update that i can do to get android auto / more stability for this head unit when i open google play it just bug out and crash the app. and Bluetooth tethering wont work with this as well. i hope there is...
forum.xda-developers.com
so i did it exactly what they said :
- os_opdate.zip on the usb stick
- settings en local update
- he strarted to update and then he came out with error status 7
- on the screen was a sort of text menu to power off and recovery etc but he was frozen so the only what i could do was power down.
- now when i turn my car key he goes on and i see my car logo and that's it or someth not even this - just black screen
I understand that maybe he stays in a sort of boot loop
i am planning to get him tomorrow out and try more but maybe is there someone who can provide me the good rom /mcu and tip about solution.
thx in advance
I have the same OS version (Eunavi 9'' for WV) and the same problem.I contact with suplier and the answer that it to old to update.
I believe that downgrade to android 9 would be better.
Any instractions to reset it and downgrade to android 9?
