I need an updated MCU (after upgrade to 6.0.1 its changed) if possible please because as you see I dont have any "mercedes" settings and at moment I can't set my Steering Wheel Controls :(

this is my first time I root a device and I upgrade it, so please every little help will be really appreciated :)

I hope my post will be also useful for people with same HU, I dont know if its me but I really didn't find anything about modding mercedes HU on web :fingers-crossed:

Thanks to everyone for the great amazing support

VPN issue

Hi every body.I have problem with all VPN programs such as Astrill and PIA(private internet access).my internet connection is fine, after I connect to vpn my internet connecting is lost and can not surf internet.I have tried many ROMs with no success.any idea?

I asked RedMod ROM developers, they tested their paid version of Rom and said the issue is there too.
[Android Head-Units] agamemnonn:
Hi,

Paid redmod rom can be used in English? redmod.ru is totally Russian, how can i purchase it to try on my r16 unit? thanks in advance.
[Android Head-Units] caspian_swan:
as i know the ROM is in English and Russian.you can contact them by Email.
[Android Head-Units] Sajito:
Hi ****-jones,

I'm having the same problem rizu3544 described, after updating to the new version you shared.

I read about that issue before installing it and saw, that unsetting BC-6 and BC-8 in config info would fix that issue.

So I installed the update and as I expected bluetooth stopped working and bluetooth name and pin were empty. I went into extra settings and disabled BC-6 and BC-8, which made it work again. But now, after the head unit was turned off and on again, there is no way I can get it to work again.

I have both BC settings disabled, I tried to enable BC-6 alone, then I tried BC-8 alone. I even tried them both together, but obviously that's not possible. I did a factory reset twice. Nothing works. Bluetooth name and pin stays empty and I can't connect my phone anymore.

Do you have any idea how to fix that? Do you need any more information maybe?

Thank you!
[Android Head-Units] dick-jones:
What firmware was before the update, on which bluetooth worked?
[Android Head-Units] Sajito:
I've had the firmware with system version V7.3.1_20170426.143705_KED3

EDIT: I think it's very strange that your fix with disabling BC6 and BC8 worked at first, but stopped working after reboot.
[Android Head-Units] dick-jones:
Ok, I'll look, then I'll tell you what to do...
[Android Head-Units] dick-jones:
Try it.

Extract the gocsdk8 file from the archive gocsdk8.rar.

Replace the file in the /system/etc/goc/ folder.

Select BC8 in Extra settings-Config info.
[Android Head-Units] Sajito:
I was a lot on road since yesterday and had no time to check this. Now I had time and wanted to try your solution when suddenly bluetooth started working again, without me doing anything. I've checked the Config info and BC8 is selected there. I've restarted the head unit several times, but it seems to be working again, which is pretty nice, but now I'm even more confused, because I don't know why it stopped working...
[Android Head-Units] dick-jones:
Just bluetooth was scared that it would be repaired... :laugh: and he himself repaired :laugh:
[Android Head-Units] Propsycho:
Dear **** Jones, Can you helpme to unbrick my unit its a eonon ga 2164, eonon sent me update files i mean a zip file with 4 files like you comment before, my eonon unit was working fine, after the update the unit stuck on logo NISSAN because i put nissan, i did ALT+PRTscren+ I, i did wipe factory reset, wipe cache partition, updates with closing key 2 to ground, pushing two times resest button, and turn acc off when push reset button and wait 5 seconds and the same still stuck, i got the links from eonon with the software, can you tell me how i can fix my unit? i hope your answer! thanks
[Android Head-Units] dick-jones:
Where did you get the logo of Nissan?

What are the properties of the picture?
[Android Head-Units] Propsycho:
Thanks for your answer!

Ok the problem it’s not the picture, but when was working fine I did the change to eonon boot to Nissan logo boot.
[Android Head-Units] Propsycho:
any way its same if it stuck on android logo or eonon logo or my car logo, y can't unbrick, I did the instructions to reflash with eonon support tech but I think the know nothing, because still bricked, do you know another method to try to unbrick?
[Android Head-Units] dick-jones:
Do you have rear view camera?

If yes, then try turn on reverse gear during load HU.

Wait a few minutes, then turn off the reverse gear.

If the HU is loaded properly, then change the logo to the standard one
[Android Head-Units] Propsycho:
All right , Yes I have reverse camera, let me try this I got to put the firmware in Sd card (four files without extension) to update I got to press two times the rst button update in progress ( in this time I got to put in reverse gear) and hold on 10 minutes ? And back again in park mode

---------- Post added at 10:11 PM ---------- Previous post was at 10:09 PM ----------

So can I use another firmware ?
[Android Head-Units] dick-jones:
No! Do not turn on the reverse gear during the upgrade!

Give a link to the firmware. I'll see what's there.

Show the photo of the device.

[Android Head-Units] dick-jones:
You do not have a kernel installed! This is the problem. Take this firmware https://yadi.sk/d/ddcg2EVV3RqTBi
[Android Head-Units] Propsycho:
all right I gonna test right now I will informe you!

---------- Post added at 07:54 AM ---------- Previous post was at 07:17 AM ----------

Ok this is the situation, for first i unzip and copy the files to SD CARD I enter to update and nothing, update ok but was to fast they don’t detect the files, the second chance i renamed the files with the same name and extension file taked from the eonon update files I did the update and the four files DONE, but still stuck in logo, reverse camera works fine, still sound the noise of radio and the volume from head unit and the steering wheel up and down the other buttons like home or back they do noting

---------- Post added at 07:59 AM ---------- Previous post was at 07:54 AM ----------

Do you think If i have to do before a wipe data and wipe cache from the boot Loader ? With an external keyboard?
[Android Head-Units] dick-jones:
sorry, wrong link.

Try this https://drive.google.com/file/d/1V-0GHmJcEcsuuw3zGvkPdQpUy4Bg9oJ2/view?usp=sharing
[Android Head-Units] Propsycho:
I don’t know why the first file it’s failed but the next done https://mega.nz/#!xsoXTLwa!rnOIYecYoPcf1RjCdtS5WOkbAWLu7ot9_isO32EmgB4

---------- Post added at 05:13 PM ---------- Previous post was at 04:37 PM ----------

Well, I think the errors caused because I use Mac but, I downloaded the file directly copied and uncompressed to sd card in this the four files was done. But still in logo camera ok and volume with the radio noise, so I think I got to trash this head unit , or there’s someth else to do?
[Android Head-Units] dick-jones:
1. Try to take another sd card.

2. Try to install this file https://yadi.sk/d/qhQ5Mla63SyQMd

If it's done, then install the firmware from the last link.

Very strange... :confused:

---------- Post added at 07:01 PM ---------- Previous post was at 06:43 PM ----------

After extracting from the archive, delete all files and folders from the sd card except the firmware.
[Android Head-Units] Propsycho:
Dear **** Jones, I appreciate and thank you very much, for all your support, today I gave myself the task of making your directions, and everything was a success, you are a good man and I am very grateful, is there anything I can do for you? You are amazing! cheers!
[Android Head-Units] dick-jones:
Of course. Tell us what helped you ... What did you do?
[Android Head-Units] Propsycho:
Ok i will write all the instructions, just one thing the radio does not work I can change the station and no sound if I use a memory with mp3 I hear the sound but if I Swich to radio can’t hear nothing

What version of the firmware are you currently installed?

Try installing your KBT6 firmware.
[Android Head-Units] Propsycho:
Ok Sorry ! https://mega.nz/#!cpgU0KiS!TJ1zOb5Zfu_H523w5BgWw4DvEYnL9mF-2PGQujAZh3s

This is the picture
[Android Head-Units] dick-jones:
Thank you. You have a special firmware installed. Therefore, the radio may not work.

You gave a link from eonon https://drive.google.com/file/d/1NN5FaPV9T6pc0aqjuu1aWNdmzOL8LB6i/view.

Try to install this firmware again.
[Android Head-Units] Propsycho:
hello I already reflash the firmware with stock rom from eonon, but still not working, I think I have to accept I don't have radio any more

---------- Post added at 10:39 PM ---------- Previous post was at 10:35 PM ----------

I think the problem is with the MCU because radio and one USB port doest work
[Android Head-Units] dick-jones:
Try to make Settings-Car settings-Factory reset (better twice)

The MCU does not have any usb ports.
[Android Head-Units] Propsycho:

Hi all,

I have similar AlWinner R16 HU (no root), some days ago in developer menu I changed the background apps limit to 4 than back to unlimited. Now the radio (same for music builtin app) is not working in background, only if it visible on the screen. But other programs(like spotify, jetaudio, etc.) are not closing automaticaly if i using navigation. Someone know how to fix this without reset? If i root the device is it possible to fix this automatic application closing issue? Thanks!
[Android Head-Units] dick-jones:
The secondary power source inside the HU may be defective. The solder contact may be missing.
[Android Head-Units] agamemnonn:
Hi **** Jones,

Hope you are well. On 4pda, i saw it is possible to change direct button controllers aux/radio/tv etc. But i could not understand via google translate. Can you help us about it in English? Thanks in advance.
[Android Head-Units] dick-jones:
I'll try. Let's start.

I did this on a smartphone using the APK Editor Pro.

You need a file com.tw.service_a5a4.apk from the folder /system/priv-app/com.tw.service_a5a4/

You need to edit the file \smali\com\tw\service\TWService.smali

Strings can be deleted, swapped, commented with a "#"

How to edit the file com.tw.service_a5a4.apk, watch the video

Digits and what they mean

:array_18
.array-data 4
0x7f040009 //radio
0x7f04000d //navi
0x7f040013 //music
0x7f040014 //video
0x7f04000c //bluetooth

0x7f04000e //aux
0x7f04000b //ipod
0x7f04000a //disk
0x0
.end array-data

After editing, the file com.tw.service_a5a4.apk must be replaced (not installed!) and the rights set to 0644.

Hello,

after quite some time lurking this thread, in which I found several useful infos (such as dev password and adb debug password) I'm at a standstill trying to root my unit. I have tried several methods, such as :

- kingoroot: when I try to root the screen flashes, asking me to "enable kingo optimization" while seemingly trying to open the accessibility settings, which seem to be unavailable on my device

- kingroot: ends up freezing after a while

- adb: my head unit isn't found by adb, even after enabling usb debugging. As a matter of fact, it doesn't even popup as a usb device on my laptop. I use a generic usb A to usb A cable, do I need and OTG cable or something?

- adb over wifi: connection refused

My device details are:

- processor Quadcore-T3 (I have seen some talk about T3 processors in this thread even though its title specifies R16 procos, which is why I post here, please tell me if I'm wrong)

- android 6.0.1

- MCU version T5.3.19-36-10-E53201-170619

- system version V8.2.3_20170809.190721_MLT1-DVD

I've noticed that yet another method to root your device is to flash a pre-rooted firmware using the update function in the car settings, would the firmware provided here be adequate?

Has anyone faced one of the issues I listed above and managed to overcome it?

Thanks a lot for this thread, and for any future help :)

Edit: side question: is it possible/recommended to update to android 7 using one of the firmwares available on 4pda?
[Android Head-Units] dick-jones:
If you have firmware for your device, then I can add root access.
[Android Head-Units] zafirbel:
Hi ****-jones, thanks for your answer, but how do I dump my firmware partition(s) without root access on my device or adb?
[Android Head-Units] dick-jones:
Can you ask for the firmware from your seller?
[Android Head-Units] zafirbel:
This might prove difficult as I'm not the one who bought the head unit, it came with the car. Are there compatibility issues with flashing other firmware version for the same hardware (such as the one you already modified and posted on 4pda)?

Edit: well I didn't do the reasonable thing and went ahead and flashed V8.2.3_20171102.171652_TW2-Orig-mod from 4pda. Works like a charm! Thanks a lot for the rooted firmwares you provide.

I have one last question: I used a Nougat firmware, would you recommend trying the same procedure with an oreo firmware, or is it too risky?
[Android Head-Units] dick-jones:
Do you have oreo firmware?

In any case, there is a certain risk.
[Android Head-Units] zafirbel:
Nope, I'm on Nougat Marshmallow. I'm not sure I want to try Oreo Nougat, I'l see.

Is there a way to dump MCU firmware before upgrading, and restore it if anything goes wrong?

I'm using one of your Nougat Marshmallowrooted roms since yesterday, it works perfectly, thanks a lot.
[Android Head-Units] dick-jones:
if it works perfectly, then do not touch anything. Let is works.
[Android Head-Units] zafirbel:
Yep, you're probably right!
[Android Head-Units] mrchrister:
My wish list for the next firmware:

- Dim brightness during Bluetooth call. Right now brightness stays on maximum

- Display Bluetooth music artist and track bigger

- Be able to sort music according to folder structure

Panel key Lights

Hi everybody,

I have a weird problem happening with my unit. I had the car in the shop for some work on the A/C where they had to remove the dashboard and then put back again. Of couse they had to disconnect the unit and reconnect it again. Now my panel keys don't follow the turn switch for the headlight, they are always on. I have tried to reset the unit but with no effect. Everything works ok except for this. Any suggestions??????? :confused::confused::confused::confused::confused:

HI, I need the help from you, the configuration of the keys panel is not working, I already changed several firmware and nothing, I think the problem is with the MCU, in my multimedia is like MCU 5.3.19-108.FF1-943101-170218-AX7 but the physical buttons not working.

The model car config is in blank!!

The "start" on Panel keys not run.

Could I get directions on what to modify in this firmware to make it work for the TW2 model? Thanks!
[Android Head-Units] dick-jones:
I also have a TW2 model and this firmware works well.

Do not change anything, just install the firmware.
[Android Head-Units] cpugod55:
So it installed without a hitch. Nothing really changed, I gained a few new options in the car stereo advanced menu and it is finally rooted. Next question...I absolutely hate the EQ that is built in, is there anyway to replace it? I have tried software side and they dont' function correctly. Is there a different factory side EQ that is better then the crap 3 band?
[Android Head-Units] dick-jones:
This is a feature of the hardware implementation...
[Android Head-Units] fridaycider:

Hi,

I'm tinkering around with some of the apps inside the firmware for this device. While doing that I had an idea to write some own apps, to extend the functionality a bit.

I wanted to follow the instructions on this link (Post #306), but the framework.jar does not contain the classes.dex, so I can't generate the TWUtil.jar.

do you by any chance have an idea how to extract classes.dex from the framework.jar in the firmware?

And can you maybe tell me how to modify the firmware before flashing it?
