Hi - i am a newbie to Android and have purchased a Galaxy S7 edge that is running a Samsung authorised Nougat Beta. Forgive me if this is wrong thread but help would be appreciated.

The phone still has 16 months warranty.

I spent a day configuring apps and understanding how to adjust settings etc and was really pleased with how well i had done and with phone and OS. i deliberately left it overnight with a low charge after my days work to see if any charge would be left overnight. Unsurprisingly there was not so had to recharge and boot up from fully powered down. When it came back to life i discovered that under these circumstances the fingerprint reader does not work and the password was required. There in was first problem as password was not recognised. i know 99.99% its the correct one as i use it on another secure site and am pretty sure when setting up Android Pay i needed to enter it to verify fingerprint reading option.

after a lot of head scratching and trying all amnner of variables and alternatives gave up and opted for factory reset. Pressing the combination of 3 buttons did nothing although my understanding was that it should be from a powered off state which was impossible to achieve as power button would only put phone into standby with date and time displayed on black screen. i eventually found 3 button press using volume down gave me a screen which seems to be downloading new software which i am guessing is new version of OS. its been doing it for over an hour now with no clue as to what progress.

can anyone give me ideas how to get phone back to life.

many thanks

*1 Force restart: â€œIf your device is unresponsive, press and hold the Power key and the Volume down key simultaneously for more than 7 seconds to restart it.â€

Factory reset:

Switch off your Samsung Galaxy S7 or S7 edge completely.

Boot into Galaxy S7 recovery mode by pressing and holding Volume Up, Home and Power keys at the same time. (Works alswo in the moment the phone force restarts by the method *1 described before)

Release all three buttons when Samsung Galaxy S7 screen flickers and you see a warning sign.

Press Volume Up to continue to the main screen of Recovery mode.

Hi all,

First of all i am not noob to flashing roms and kernels. I have been flashing rom/kernel since 2011 on different phones. But i never encounter this type of problem. On my N6 i cant get root on my stock rom(not debloated rom by tupac4u).I have tried different supersu zips(2.78, 2.78 SR3 and SR5) but no luck. What i did, went to recovery wipe everything except internal storage, reboot to bootloader, flashed latest factory image( which is NDB91P), setup my device, reboot into bootloader to flash recovery(because you loose twrp when you flash stock images), then flashed SuperSu (tried every versions) and i always get bootloop. Am i missing any step??:confused:

[Android Head-Units] Airwin13:
Hi everybody,

there are some new Android head units around with a bigger screen than the current double din ones. The resellers often calls them "Tesla Style Headunits". Sadly I've not found much information about it, yet. So I bought one on the SinglesDay in China via Taobao to check it out.

I already did a lot of research on the Internet about these things. But until now, I've not figured out who the actual manufacturer is. I think with these units it is the same like the MTCB/D, one manufacturer and lots of resellers. Here is a Link to a site that lists lot of theses units with the specs. But of course they are nearly the same. The only difference I saw was 1GB vs 2GB Ram and 16GB vs 32GB Rom. http://www.cusptech.com/index.php?c=products2

I tried to get to recovery mode, but no luck until now. But just in case something bricks while testing or to optimizing the Rom, it would be great to have the update.img. For that I contacted the reseller, but get the normal bla bla bla. Its stable (yes of course :silly:) and no updates are planned and so on.

On youku.com I've found a video, where someone did the update http://v.youku.com/v_show/id_XMTU5NjkwNDEyNA==.html. So it must be possible somehow. But my Chinese is not the best, so I can't contact that guy :)

So if anybody has more informations of any type about these units, would be great if he shares.

For anyone who want more informations, here is a review on YouTube in Russian https://www.youtube.com/watch?v=7Pa0T8AsY5k. If someone knows Russian, maybe he could contact iqnavi.

Thanks
[Android Head-Units] CadillacMike:
i dont have any info, but i would like to see more units made for newer cars
[Android Head-Units] Airwin13:
There are some small updates.

First: Rooting via Kingroot is possible.

Second: I've managed to get the SystemApps and found the Bundle ID's com.choiceway for the launcher and com.szchoiceway for other apps like radio. But google it, did not bring any results :mad:

Further I was able to decompile the settings APK and extract all factory Pin codes. For now, I won't post it public, to keep the risk that the manufacturer maybe changes them, as low as possible. But if you are interested in them, you can PM me anytime. If interest is increasing, I will post them here of course.
[Android Head-Units] Airwin13:
Update 3

With the root I've found some config XML Files. The files are all called "customer_***.xml". There are 12 of them. I think they control the GUI for the different resellers. So I have merged all options into one XML-File and got all the GUIs available. The two "Customers" with the bigger XML-FIles are OCCAR (奥车凯) and Carcool (车酷时代). I don't know if they are manufactures or resellers, but my circuit board is also labeled with OCCAR, so I think they are manufacturers. Searching with the Chinese names I found the websites of these two. http://www.occar.cn and http://www.carcoolera.com / http://www.sz-carcool.com. I tryed to contact them via the WeChat App, but they did not response. Maybe they don't speak English.

Is there anybody here, who speaks Chinese and could contact them for me, please?
[Android Head-Units] bonez_ru:
HI Airwin13!

I just ordered the same device for Ford Kuga 2014. I ordered it from other seller then you. Now DVD is on the way to me, but i got the firmware update.img from seller.

I have unpacked it with RKTOOLs and looked inside. Now there is 20 customers.xml files.

The first question is - can we add other languages then china and english?
[Android Head-Units] Airwin13:
Hi bonez,

thats awesome. One of the best news in 2017 until now ;) Since the start of this thread and today, I contacted nearly 12 resellers and manufacturers, without any luck. Could you please upload the update.img somewhere for me? I also would like to inspect it. Maybe i can preroot it, so that Kingroot is not needed anymore. Did he also tell you how to get into the recovery mode?

So they managed to get 8 new Resellers. Lets see, maybe they also added some new Interfaces.

Adding languages should be possible i think. I decompiled some Apps Like the Launcher.apk and Navisettings.apk. These two are building the main GUI. And there are lot of strings to translate :). Examples are at the Attachments. Then there are of course even more Apps like the Radio, Music, Movie and so on. So I think its possible, but means a lot of work.

I will send you a PM with the pin codes for the factory settings.

Great to finally see another user with these units :good:
[Android Head-Units] Wadyas2009:
Hi Airwin23.

I also purchased these Tesla Head units for my 2017 Toyota LC.

I too wanted to try and optimize these units as with 1GB ram things can get slow.

However I would like to note that out of the box my unit was already on version 5.1.1 however still shows up as KitKat ? It also has a date of 201612xx which is later? Hope this helps.

Also how did you root ? Really don't want to brick my new unit.

Also a interesting note is the ram mention 625/2G where on your screen shot shows 1GB. However when I look into running apps, my total ram is 1GB so not sure what is happening here.
[Android Head-Units] typos1:
These units use a Rockchip RK3188/PX3 which can take up to 2GB RAM. MTCB/C/D units also use this chipset and several of us in the MTCB forums have bought new RAM chips and upgraded to 2GB, from the pics it looks very likely that these units would take the same RAM modules.
[Android Head-Units] Airwin13:
Hey Wadyas,

you are right, 1GB of RAM is really not the optimum, 2GB would be way better. But I think typos1 is also right and an RAM upgrade should be possible. If you are interested in that, I can took a picture of the other side from the mainboard, there you can see the RAM.

Where do you see thats its version 5.1.1? Could you make a screenshot? Until now I have only seen KitKat Versions of these units, would be cool if they updated it.

I rooted with the Kingroot.app. But you should be careful with that, once rooted its very hard to get rid of the Kingroot App again. Factory reset does not help in this case.

I think you should trust the Android information screen. The YXZ/2G Info is, as far as i know until now, only a string inside the Navisettings.apk and outputs the info depending on the vendor set in the customer.xml. So I would say its fake and your unit also has 1GB of RAM. You could also check it with the CPU-Z App.
[Android Head-Units] Wadyas2009:
Andriod 5.1.1

Spoke to the reseller. He mentioned they made the update to fix the issues with mirrorlink. Not sure about this as I could not get this working. Advisers to install MOB Interconnection service.??

Also how do I post the screen shots ? Usinf mobile version? Any other quick way?

Do you upgrade the Ram to 2GB?
[Android Head-Units] Airwin13:
So did the reseller send you an update file or it was already installed, when you bought the unit?

Sorry I don't know what the "MOB Interconnection service" is. But I did some research on Google. Looks like it's a Framework used by the Mirrorlink (EasyConnect) App. But I don't know, how to fix that.

That's a bit difficult, because the statusbar is hidden by these units. You could install an APP from the Playstore or just do it oldschool and took a picture with your smartphone ;)

No, I'm still on 1GB. At the moment I don't have planed to upgrade.
[Android Head-Units] PatrickHenninger:
I have two update files for these units. The units I ordered are 10.4" Vertical oriented for 2015 Mustangs. I was able to get the software from the supplier, and I would be happy to provide people with the files, but I'm not allowed to post links to my Google Drive or Dropbox.

Also, we have already extracted the img files and checked the build.prop and everything we could find, but I'm not savvy enough to know, is there a way to remove the password for advanced options on the unit, by using the img files?
[Android Head-Units] Airwin13:
Oh thats cool. Could you mybe send me the links via PM, then I can post them for you if you like.

Why would you like to remove them? I will send you the codes.
[Android Head-Units] Wadyas2009:
Headunit

No came pre-installed. I asked for the update file but he didn't have it. I've got screen shots in the below link which I hope helps.

dropbox.com/sh/is9en84yi7lilr2/AADVXVArAvkdIZQI7-4DyZhia?dl=0[/url]

You mentioned that it will be different unrooting. Are you saying this will just take time or impossible? I want to disable allot of the programs to save Ram is that makes sense or is there a better way to do this?
[Android Head-Units] PatrickHenninger:
Does anyone think they could find out what a PIN code is by having the source files of the image? I have tried all of the common ones, to no avail.
[Android Head-Units] Airwin13:
Rooting is possible via Kingroot, like I said. It's just hard to get rid of it again, if you don't trust the Developer of Kingroot for example or because of any other reason.

If you only want to save RAM and not Space on the ROM, then I would recommend to first try to uninstall or disable the unwanted apps via the settings menu. If you don't know how to do that, maybe this helps https://www.youtube.com/watch?v=puTFvKFNyH8
[Android Head-Units] Airwin13:
Many thanks to PatrickHenninger!!! He organized two images. Since he is not allowed to post links at the moment, he asked me to do that for him.

Until now, I have not flashed or inspected these images. So I can't give any further informations at the moment. If you decide to flash it, you are using it at your own risk. I'm not responsible for any damage at your units.
[Android Head-Units] toologic:
bad links :(
[Android Head-Units] Airwin13:
Sorry, my mistake. Please try again.
[Android Head-Units] PatrickHenninger:
After spending time with those files this weekend, the first is just the 4.4.4 image that came on my unit, the 2nd file is the 5.1 upgrade. The downside is, they are designed around the Mustang, so it will have a Mustang-themed boot screen, as well as a Mustang in the launcher.
[Android Head-Units] marcus82:
Ok I'm trying!!!

Where can I find the packages name? In any system dir in the head unit? Cause for sure for spotify should be com.spotify but for the radio?

Another question for all here: after new russian firmware update, the gps connection is too much slow. Is it the same for others?
[Android Head-Units] ikuznets222:
sysApkLst is the list of programs that you want run without muting stock apps - that's the point. Radio is a stock app.

If latest FW is not working correctly in your case, you can rollback by reinstalling previous one. All apps will be retained. The only difference in July FW is a new 84 theme for mazeratti.
[Android Head-Units] marcus82:
Ok now I completely understood! So I can't solve the problem that stock mirror app mute Spotify?

Inviato dal mio ONEPLUS A6003 utilizzando Tapatalk
[Android Head-Units] ikuznets222:
obviously they just grab aidiofocus from one another. The same way you can't have 2 audio players sounding at the same time. Mirroring app has in mind that you may want to broadcast audio from your phone to the unit
[Android Head-Units] marcus82:
you're right but the right behaviour is to mute the audio, like the phone app do; instead now the mirror app kill the app!
[Android Head-Units] ikuznets222:
Try adding com.spotify as sysApkLst package. This will protect it from being killed by Launcher. Mirroring app (easyconnect I believe) doesn't have authority to kill anything
[Android Head-Units] ramathorn1982:
Long time listener, first time caller...

I have several questions I'm hoping others have run into. I'm pretty deep in the Russian forums using Google translate. There is some great information there but it's difficult to find specific information on topics because you need to be able to search in Russian. Here are the modifications I've performed using the information from both here and the Russian forums:

1. Flashed firmware using the Phoenix Android Image.

2. Rooted using Kingroot.

3. Changed Music.apk, BT Suite and Radio.apk to the "dark" custom APK the Russians made.

4. Changed bootup image.

5. Changed vehicle image (Ram truck to Ram logo)

6. Added Car Launcher Pro.

The issues I'm having are:

1. Sometimes the steering wheel controls don't work.

2. Is it possible to control my Digital TV tuner from the headunit? I have a tuner hooked up to the AUX lines no problems, but I see a "TV" app on the unit and I've seen video of the tuner being controlled with the touch screen. I get "no signal" on the TV app.

3. I get "no signal" on the DVR and all on screen buttons are dead. Can you assign any camera to the DVR or must one use a USB camera for this to work?

4. Is it possible to assign different apps as "music" apps for Car Launcher Pro? I want to add the stock radio app but it's not recognized.

5. Some of the themes fail to load correctly if using Car Launcher Pro (top and bottom bars missing or screen is landscape).

Any help would be appreciated. I'm willing to answer questions too as I've done a bit of tinkering with this radio.
[Android Head-Units] cdrkeen:
Changed Music.apk, BT Suite and Radio.apk to the "dark" custom APK the Russians made

Where did you get the Music.apk and how did you change it, uninstalled the old and installed the new? just like that?

Have you attempted changing the event....apk to modify the top menu bar?

You do know that you can also change from having just a boot logo to have a boot animation as well making it a bit more obvious that the unit hasn't froozen yet? Since you rooted your unit you can easily use any boot animation changer ...or even make your own.

Does your Car Launcher Pro show the playcontrols for when playing music via bluetooth correcly? Because on mine the controls work for youtube and spotify but not for the bluetooth app.

Regards from DownUnder

[Android Head-Units] ramathorn1982:
I will respond with details from my PC in the morning. I have several APKs for the music app. I don't believe I have enough posts to add pictures...
[Android Head-Units] marcus82:
I've substituted Launcher.apk with the modified but nthing change.. unfortunately

maybe I can try with the radio that is stock
[Android Head-Units] ramathorn1982:
I got the Music.apk from here https://4pda.ru/forum/index.php?showtopic=877711 (the Russian Forum). If you translate it to English look at the Stickies at the top of each page. The Section you want is "Additions/Improvements/Changes" -> "MusicPlayer" . There are 4 options to download there. I'm using the MusicPlayer_ver.05072018.rar by member ShIvADeSt which has a dark grey theme and I believe some changes to the way songs are organized when the browse feature is used. To install, copy the stock APK from /system/app/MusicPlayer.apk and back it up somewhere safe. Then rename the custom player to MusicPlayer.apk and overwrite the stock APK in /system/app/ (root with write permissions required to be enabled in ES file explorer). Then restart the headunit and enjoy...

I haven't attempted the removal of the top and bottom bars yet, but there are also instructions for that on the Russian forum listed above in the "Additions/Improvements/Changes" -> "Hide both bars - at the top and bottom"

I may dabble with the boot animation just to have it do something while it's loading besides looking like it's frozen.

I checked the BT to see if car launcher pro can control it correctly and it appears to have the same issue as all of the stock apps. Car Launcher doesn't "see them" as music players so you can't select it from Car Launcher Pro to control. This is something I would really like to figure out as I would like to be able to select the active player (to include the stock Radio.apk, Music.apk, and BT music.apk(?) ) from Car Launcher Pro and hide the top Navigation Bar.

I do have another strange issue, every time my phone connects to the radio via Bluetooth it auto-dials " #*#0 " does anyone know how to make that stop?
[Android Head-Units] cdrkeen:
Mine does NOT autodial. Maybe it's something with your phone's setup? I use an Iphone7.

To change the boot animation use Rom Tool Box lite.

Not sure if that will allow you to use custom animations. that you can make with this https://xdaforums.com/showthread.php?t=1792178

Thanks for the Russian Link. Will Check it out.

Mine still has issues with the AC Temperature control (thats in a Mitsubishi Pajero Sport / called "Montero" in the US I think). Changing Temp changes the Fan speed but not the temperature unless I set it to max (32) or min (18). The vendor suggests to replace the xfy Canbus.

Hopefully a replacement canbus may fix it.

I think the stock apps aren't working im the car launcher widgets because likely they lack MTC support.

I'd wonder if flashing the unit with some alternative image and then using stuff like this

[RockChip] MyMTCService (RK3188 / PX3 / PX5) (check playstore)

but then I'm scared that my AC and other hardware stuff may not work anymore without the stock rom.

So better to make a list of desired requirments and keep nagging the manufacturer from all sides with the same requests... then eventually they'll prioritize customer requests as they must want positive feedback to sell more of them.

Getting mediocre reviews does not help them flooding the market.
[Android Head-Units] ikuznets222:
TV app is there for a special chinese TV module connected to multi-pin socket on the rear, not some AUX-type TV. Same about DVR but you can try UVC ones (because there's a kernel driver for that), but I don't guarantee they'd work. Most likely you need a DVR specifically crafted for this app (btw different DVR apps came in different FWs over the years)

You don't see icons for various stock apps in custom launcher because they're having incorrect xml-structure in their AndroidManifest.xml so that custom launcher fails to catalog them correctly as launcher shortcuts. Look for <intent-filter> and <category android:name="android.intent.category.LAUNCHER"/>
[Android Head-Units] marcus82:
guys, did you resolve the call volume problem?' is too much low then radio/music one
[Android Head-Units] ikuznets222:
This cannot be resolved as relative volume levels are hardcoded in mcu firmware and loaded into BDA chip during mcu boot.
[Android Head-Units] marcus82:
too bad!!!!! :(
[Android Head-Units] marcus82:
maybe we can modify the radio volume turning it down
[Android Head-Units] ramathorn1982:
Thanks! So when I look for the malformed bits and modify them will that break their use in the stock launcher? If so, I wonder if I could just make a second copy of them and modify that, then have Car Launcher Pro use those instead?
[Android Head-Units] ikuznets222:
Those are not malformed bits but rather some slight incorrectness that leads to the issue. Unfortunately I forgot what it was - might be multiple lines in intent-filter where it'd rather be separate intent-filters with single line each or something similar. You can experiment. It is not likely to affect stock launcher. Regarding changes - you can only have 1 copy of each package on your system. So I suggest you download all apks in question to a safe location on your PC, remove those apks in /system/app, make a copy of downloaded apks to some EXPERIMENTAL folder and proceed with apktool, modifications, reassembly (remember you can't use -c option to keep the original certs bc you work on manifest). When you're ready - copy those apks back to /system/app, verify 644 perms and reboot. After reboot - check for package existence on CLI (pm list packages | grep choiceway). If something goes wrong, put those packages back from a safe location.
[Android Head-Units] ramathorn1982:
Thanks again! Looks like I have some skillsets to develop but that's one of the reasons I have this radio (and it only cost me $75)!

---------- Post added at 01:21 PM ---------- Previous post was at 01:16 PM ----------

Thanks for t he info. My phone is an Android and has done the same autodial for two separate ROMs now. I'm thinking it may be something from the Russians that got lost in the translation when I used their custom Bluetooth Suite APK.
[Android Head-Units] l33boy:
Ah right... No way to get Developer enabled? That is a problem!
[Android Head-Units] marcus82:
YES, A GREAT PROBLEM!

It's strange cause when I click on developer options, it ask me a password but after typying I have no error, simply nothing happens and I have the page of system setitngs
[Android Head-Units] l33boy:
Can you not enable developer when in the setting menu? Which settings menu?
