[Android Head-Units] TheSSJ:
You should have 2 wires coming from the radio named Key 1 and Key 2. You need to wire them correctly to the cables coming from either your car or from the CAN decoder. Do you have a CAN decoder which was sent with the unit? Does it have 2 loose cables maybe called also key 1 and key 2? Or SWC1 and SWC2? If not, then there should be 2 cables coming from your car directly. You would need to identify these by searching a pin diagram (basically a picture telling which cable from the car has which functionality.

Maybe there is only 1 cable, maybe 2, rarely 3. If it is 1 cable, then try the following:

Connect Key 1 to this 1 cable and leave key 2 as it is (maybe wrap it up in some duct tape so that it doesn't have contact with anything else.

If you have 2 cable try this (assuming they are named like SWC+ and SWC ground:

Connect key 1 to SWC+ and connect SWC ground to the ground of your car (not to key2, leave it unconnected)

If this doesn't work do the opposite with key 2 leaving key 1 unconnected. Kaween posted a good guide here (difficult to find, though :) )

Well,if there are 3 cables coming from your car, then they should be SWC+, SWC- and SWC ground...

Unfortunately I wouldn't know how to connect this correctly, maybe by wiring SWC+ with key1 and SWC ground to the car ground again, but it's just a wild guess...

Never seen something like this :( Sorry, I don't know if the firmware files would even work on your unit...wouldn't risk it to be honest (if you look up some pages back you see that I learned my lesson by touching a running system :D)

Sorry!

Did it already boot like this or did you flash a random firmware update? ;)

Check your About screen to maybe see which manufacturer is the correct (Kaier, Anstar or others)

Kaier

Anstar

Create

As always: flash at your own risk

Edit: got the links from here (if anyone understands russian)

Geez, this Aliexpress auction looks a little messy with all these coloured images :D

Well, if you are able to root your device (check the AN21 wiki or the very first post on page 1), even temporarily, you could make a backup of you MCU residing in /system/etc/mcu. There should be a bunch of zip files (or even only 1). Copy the one matching your version.

As for the system upgrades they are pretty much universal (except for the screen resolution. The Aliexpress link mentions 800x480). See this link, I'd choose the 2.8.8 perm root one. I think I've read somewhere that another user also have this very version flashed and is pretty happy with it.

As for the MCU, I think versions with 650101 at the end should work, too. But please, please make a backup before doing anything to your MCU! If you shouldn't find any files on /system/etc/mcu then I personally wouldn't make anything on the MCU part (system can be upgraded nonetheless IMHO)

I have installed firmware from the Russian forum, I think it looks cool?
[Android Head-Units] darkromance:
Thanks for reply

Yes i fashed random firmware :(, don't tell me why, I don't know what it was in my head that day

It was a jrnav pure android http://it.aliexpress.com/item/Andro...-C-Triumph/2035930212.html?recommendVersion=1

i flashed tonghai firmware 2.8.6

so everything is working well, even better than before, exept for the resolution

do you think that i can solve flashing this?
[Android Head-Units] TheSSJ:
Yeah, these System upgrades are pretty much universal...there are just differences between the resolutions AFAIK. I'd flash the Anstar firmware and see if everything is fine again.

What you can do is to ask the aliexpress seller to send you a link to the firmware, most of them are really supportive, even with the language barrier :)

d90 audiosources 4.2.2 root problems - same as AN-21 U

have some problems to root my d90 - 610 Android 4.2.2 from Audiosources . Is the same as AN21-U .

What can i do ? any ideas ?

baidu root and this part don't work.....

Download the required files above.

Install Android Terminal Emulator on your unit.

Open the AUX application and close it.

Install Root My AN-21 U and create a link on the homescreen.

Run Root My AN-21 U and press the "Step 1" button.

Reboot the unit.

Once the unit has rebooted the screen will likely be black, press the Home button to display the homescreen.

Run Root My AN-21 U and press the "Step 2" button.

Reboot the unit.

Open Android Terminal Emulator and run the following commands.

Code:

su

rm /data/local.prop

Reboot the unit.

best regards
[Android Head-Units] TheSSJ:
Hi,

you sure that your unit is an AN21? On a German forum I read that it takes 15-20 seconds until the radio music plays? Can you post a screen of your settings->about screen? System Version and CPU are interesting to check what can be done.

Cheers
[Android Head-Units] Shadow128:
Hi there,

once again my old (and new) questions ;)

5) Can I change the function of the Hardware-Radio Button? I'd like to use it for MP3-Player

6) Can I use an "external" MP3 App, which starts automatically after system start and save the actual playlist/playtime?

Yesterday I tried Rocket Player, but after switching off and on, the system starts not the Rocket Player. Also the actual playtime was not saved

Thanks,

Shadow128
[Android Head-Units] TheSSJ:
Let's see what I can answer here...

1) to be honest I don't know if an MCU upgrade would show you additional info. Do you have a Can bus decoder which was shipped with your device or did you just wire the CAN+ and CAN- cables?

Maybe the Android SW is doing the decoding, but I can't tell for sure (as I understood the MCU is doing the more "basic" stuff, see here)

2) You can for sure do it yourself, but you need some knowledge about de- and recompiling and basic programming (not the "BASIC" programming language ;) ). There are some cool tools around here, just search for them, they will do the decompiling and you just need to alter the code. Maybe you can compare the one modded BT app with the current versions and see what needs to be changed (in my mind these should be just a few code lines).

5) You can change the mapping of your hardware buttons, but I don't know if you just can map it to an app? Settings->General->Extra Settings-> after scrolling a bit there should be an entry change button mapping or similar (not the steering wheel control, although the UI is the same)

6) No clue, I think kaween tried renaming a media player just to the same name the original media is called but it didn't work as I recall. But I can't guarantee that there maybe IS a possibility (maybe with some third party autostart app?)
[Android Head-Units] edustsbr:
Personally, after updating to latest version(System Version 2.7.29), this appearing this message: "UI Unauthorized, please contact supplier.", someone has a solution? I searched the forum, but it does not find anything concrete.

Thank you
[Android Head-Units] TheSSJ:
Hi,

for this you must be rooted and have a root explorer!

you need to replace /system/app/com.tw.service_a5a4.apk with this one: http://xdaforums.com/attachment.php?attachmentid=2854771&d=1405521447

You need to rename the downloaded file to com.tw.service_a5a4.apk and then replace it.

_________________

Option 2: Flash a firmware from here (check first if you have 800x480 resolution):

https://yadi.sk/d/tbaxJYL9cJjKK/Firmware

I suggest 2.8.8

Cheers

Regards
[Android Head-Units] edustsbr:
ok, if a problem occurs, I can restore a previous version?

This 2.8.8_TT_permroot.zip version, comes with root?

My resolution is that yes, 800 * 480

These versions are safe because they are not here in the forum?

Thanks for your help!
[Android Head-Units] TheSSJ:
Hi,

yes, downgrading is possible (saw some posts in this thread where a user went from 2.8.8 to 2.8.6 for example).

What you

maybe

need to do to root it is to run baidu root one time to have root permanently working. Then you can switch over to CWM superuser, update the su binary and reboot once. Afterwards you can uninstall baidu root. (this is purely optional, though).

The russian colleagues maintaining the yadi.sk drive do a pretty good job with this and there were no complains as far as I know...you can search this thread though to go extra sure.

Regards
[Android Head-Units] Shadow128:
Yeah, thx for the first help :)

1) There was a can bus decoder delivered with the radio, but maybe some one has experience with excact that drive model and can tell, if it works or not. Otherweise I try to flash another version. Original MCU version I found here, or can I also download the excactly mcu firmware from the radio?

2) Ah ok, didn't know that there are ready decompiling tools. Then I'll try, I think if i get the source code it should be no problem to find the sort-part

5) I try tomorrow if there's the option in my car

6) That sounds not good :/ The original player is ok, but little things that are little bit stupid. Don't know if the developer of the apps also use them :D

[Android Head-Units] Shadow128:
Thanks for that tip :)

I'll try to modify the skin modded apk from the bluetooth app
[Android Head-Units] TheSSJ:
1)Well, the decoder does all the reading stuff out of the can bus, so if the decoder just ignores climate control feedback etc. I don't think the MCU can help out here.

2) I decompiled the sorted BT app and one from the current builds. Unfortunately the apks are scrambled, which makes me lose the overview :( all class names have just been replaced with alphabet letters. I found out, that the name sorting BT app just has 2 calls of the sort-function inserted (just 2 mere code lines). Unfortunately (because of the scrambling) I don't know where to place these 2 function calls (the class init-methods look all the same :( )

6) Definitely not :D They add fancy buttons and stuff, but the simple things are just not implemented

Factory reset won't help here. Just a question on this matter: I saw in the aliexpress offer this little piece of information:

Risoluzione: 1024*600( add usd20)

Did you add 20 bucks to get the 1024 resolution? Otherwise I'd just try another 800x480 FW (maybe you accidentally flashed a 1024 FW the first time already while having a 800x480 unit? I don't know.) It's worth trying as you see that these FW packs are pretty much universal.

I'd personally leave the MCU as it is. Concerning the android system firmware I shared the link for pretty much current Firmwares a couple of times (look for a link to yadi.sk).

I have worked out why the app Car Settings disappeared.

The app is actually in the MCU file, when you select a car model, if the app is compatible with your car model, then it will install to the unit, otherwise it does not install.

The car settings app allows you to set the OEM features available to your vehicle.

It's guesswork as to what model to choose, I have a 2014 Outlander and I am using the VW Golf model as it loads the app and has various settings?

I have not checked all the models that may work with my Mitzi Outlander, I still have to try each one individually. :cool:

Bluetooth is definitely flakey in my experience with this unit but definitely usable I use

V2.9.1_20141217_800X480_SYSTEM_KED.rar, 2.9.3 give me the red text u can try any just be sure to use the right resolution and dont downgrade too low personally I stay above 2.8.8 but that 2.9.1 has been pretty good I know if my phones not on or in range when radio first boots it usually wont connect by itself and once in awhile the person on other end cant hear me.

from the link pieranio gave above ive used 2.8.8_TT_permroot.zip and it seemed pretty good and comes with the root directions and files I don't think I rooted 2.9.1, for my needs it hasn't been absolutely necessary though I usually like to.
[Android Head-Units] Codykeefe84:
The 2.9.1 did work for me but what keeps happening to me is right after I flash it with new firmware the bluetooth works flawlessly but if I turn the car off and then restart it it doesn't work at all. Has this happened to anyone? The bluetooth settings erase themselves. I don't understand it.
[Android Head-Units] ryan-mc:
ive noticed that but when I leave them default it seems to hold pretty good the only thing I change now is pin, are you changing the name ? I usually change the pin, pair it and then I don't usually go back into settings and it seem to hold
[Android Head-Units] Codykeefe84:
I'm not changing anything. I have flashed alot of firmwares now and the same things keep happening. The one cased my music play to not work at all.
[Android Head-Units] ryan-mc:
are your apps and misc settings retained when flashing? I noticed thee newer ones seem to be more of an upgrade and keeps old settings and apps maybe somethings hosed and not being wiped out, I think 2.8.8 tt permaroot wipes it all except for the sdcards
[Android Head-Units] Codykeefe84:
Yea the last couple of flashes haven't wiped anything off of my unit. They have only been 2 files each flash. The first couple that I tried had 4 files.
[Android Head-Units] ryan-mc:
one time I had a failed root and it knocked out my wifi and maybe Bluetooth too cant say for sure but maybe try 2.8.8tt(to achieve full wipe) and then upgrade to 2.9.1 the other thing I noticed is that rebooting the unit isn't always a reboot it seems like more of a sleep/wake so not a true reboot so the hardware might not be fully resetting and staying buggy.
