[Galaxy S6 Q&A, Help & Troubleshooting] honeybadger1121:
Hey

Disclosure: I haven't played around much with rooting but I got a Samsung S6 SM-G9200 Model from China and wanted it get it up to speed with google services and such so I tried to follow instructions from rooting videos, downloading Odin 3.10 and the right software for TWRP.

I was able to get it to work but when I tried to work with google services, nothing ran. So I tried to unroot and reroot after realizing there were two different types of .tar or md5 files I had to use Odin to (flash?) onto my phone. Now I've tripped KNOX, tried to unroot and reroot, but TWRP is still there but SuperSU isn't. When I try to select the booting options (or any options) from TWRP screen, nothing responds. The power button locks, but I can't unlock the screen or anything.

I've tried looking around for answers, but I don't know how I can operate TWRP from my computer without having the softwares on my phone, nor do I know how to remove TWRP and try to re-install it to see if it will respond. Still don't have google anything.

I mainly want the phone to function like it would an American/Canadian phone so I can access the apps i want and remove a bunch of the installed apps from China (everything base, even the download window is chinese).

Any advice on how to proceed? I've been searching for a while now but I'm getting lost in a lot of general answers. I'll need a step by step for things related to the phone since I haven't programmed anything substantial before.

Thanks in advance!
[Galaxy S6 Q&A, Help & Troubleshooting] davebugyi:
TWRP has the touchscreen drivers built in, so probably the one you flashed does not have them for the SM-G9200.

Also, you can try Philz Recovery, where the hardware buttons also work.
[Galaxy S6 Q&A, Help & Troubleshooting] honeybadger1121:
Thanks for the reply! Would I have to unroot first or can I directly flash that and proceed to see if TWRP works?

Thing is the first time I went around with the TWRP, it worked but afterwards it stopped working.
[Galaxy S6 Q&A, Help & Troubleshooting] davebugyi:
Root has nothing to do with recovery (unless you want to flash it from a booted phone) :) So you can flash it straight away.
[Galaxy S6 Q&A, Help & Troubleshooting] honeybadger1121:
Hey again... I'm so lost as to what I'm supposed to download from there. I downloaded each of the three links but none can be opened in Odin to flash (???)

At this point I just want a way to put google apps onto my phone - is there a step by step to do that? So far I haven't been able to directly download apk files and have them work. I keep getting the message, " Google Services stopped working" or If I try to log in with my account, it says " cannot communicate with google servers"

Any pointers?

Thanks in advance!

I got my touch screen in recovery working on my SM-G9200 by flashing the sprint version (I am using an a different international carrier and not sprint, but for whatever reason, it works)... Works perfect, I even backed up my phone and restored all working 100%... I cannot find the download link i used but the file is inside the zip attached below... Extract the zip file and flash the .tar file in odin... However this won't fix your "Google Services stopped working" problem, which is a different problem entirely and not something I am facing on my SM-9200

This will be my backup plan.... coming to canada soon?!!??

I'll try this and see if TWRP responds.

I"m about to break something here...
[Android Head-Units] qtpie70:
I just wonder if anyone has setup a front dash camera with RK3066/RF3188 head units. What application do you use to to record video from USB front camera in the background? How do you configure this application to launch automatically on boot and start recording immediately in background?

Thanks.
[Android Head-Units] wigglitz:
I have set up some USB cam apps. Right now I'm trying to get composite IN to record, but. So far "CaroO Pro (Dashcam & OBD)" has worked out the best for me. All of the settings you're asking about are easily located and configured in the app. I can have it start with movement/when my car starts/when I tell it to. It also has the option to run in the background. The other feature it has is a floating widget if you like to either see your car information. Or to take you back into the main app. Another nice thing about this app is the it connects to your bluetooth OBD adapter if you have one. Giving you a lot more information if you are looking for that sort of thing. My second choice is "AutoGuard Dash Cam - Blackbox". It does not have as many bells and whistles as CaroO, but it gets the job done. All other apps I have tried have been more of a hassle to use and set up. I would suggest trying free CaroO trial and seeing what you think. I am not sure if this helped at all, but I will be here to answer any other questions if you have them.
[Android Head-Units] jwonnacott:
Has anyone got this working?

I have an Eonon G2110z head unit running KitKat and am trying to set up a dash cam. I have tried a "video in" camera (which i'd prefer to use) and a usb camera but all the dash cam apps I've tried ( about 10 I think) say they can't find the camera.

Is there any way of telling Android that the video in is where it expects the phone camera to be?
[Android Head-Units] wigglitz:
My USB camera works perfect and almost all apps recognize it. It's one of those board cams they usually use with Raspberry Pie/Arduino. It seems for the best results to look for a UVC compliant USB camera. I am not an expert in any way with these standards. But they seem to be highly compatible with Linux/Android due to them only needing to run off of a generic driver like thumb drives/external drives.

As for the video in/AV/RCA type, I still have not figured this one out :/

*A not much help rant that can be ignored: I did get an image to show up from my dash cam using a dumb/convoluted way. But it would always freeze. The flow was: micro HDMI on dash cam to standard HDMI to an HDMI digital to analog RCA converter. I have also tried the 2.5mm AV out on the cam to RCA. I think it was the same result, but now that I write this I want to go try again...

Sorry I am not much help. I hope you get this figured out. If you do, I would be forever thankful if you shared your results :p
[Android Head-Units] rudix78:
I'm currently using Daily Roads with USB camera usually sold with those headunits. Problem with this apk is that it can't save last recoded file (when you switch ignition off). Can you confirm that carO pro saves last file properly?
[Android Head-Units] jwonnacott:
Many thanks for this, I'll see if I can grab one of those UVC compliant cameras.

It seems to me that the apps just look for what android presents as the phone camera- maybe the trick is to get android to think that the av is the phone camera?

AV plays perfectly on the screen when I select the video player.
[Android Head-Units] illmatik:
I used the DailyRoads app with a Logitech USB camera with decent success. I had to use another app to auto-launch the DailyRoads app on bootup. The only issue that I had was the camera picture seeming to get too bright or too dark in some situations. Manually stopping and re-recording the video seemed to fix the picture, but this was not ideal.

Since installing my new headunit, I'm going to give some other apps a try to see if the problem lies with software or my camera. Thanks for the suggestion on CaroO, I'll give it a shot.
[Android Head-Units] wigglitz:
Sorry for the late reply. I meant to check that night. I tested it twice with car0. Once turning the car off and letting the head unit sleep. Then turning back on right away. And again but let the unit fully power down and boot up. Both times Caro0 saved the videos perfectly fine.
[Android Head-Units] shauneco:
That Caro0 app works well but doesn't "Autoload at start-up".

I've installed a basic app that autoloads Caro0. Autostart - No root

In settings menu it only gives me option to save video to internal memory, Anyone any idea how to change from within the app?.
[Android Head-Units] carbonad:
What USB cameras are everyone using? I want to pickup a cheaper one to test and see if I want to run a dash cam.
[Android Head-Units] wigglitz:
I have no problems getting Caro0 to auto start. It'll open the app back up when my unit boots if that was the last screen I left it on. Or I have the setting checked to auto start once I begin to drive. I will have to look where my files are stored. I remember having issues with this too. I'm pretty sure I have them recording to a flash drive now. I will check.

This

is the camera I am currently using. I had a friend use their 3D printer to make a case for it. Although, no matter what recording app I use I everything is too dark. It might be just the camera, but I'm looking for a way to make the overall image brighter without being over exposed. I think I'm just going to buy another soon anyways...
[Android Head-Units] 1234qwerasdfzxcv:
Hi guys!

Any luck with AV IN (RCA) video recording from back/rear/reverse camera? I have a Joying rk3188 JY-131 unit but not any look. The device coming with 2 cams, front\DVR is USB with night vision, the rear is analog camera. The front camera is not very good because IR LEDs working continuously and that make the video and picture quality very bad at day light :( Some suggestions to fix that problem?

I had an android rear view mirror and it can recort simultaneously with front and back cameras. The program is FireEye.apk, i tried to install a different versions at my double din, but no one work.
[Android Head-Units] licht77:
Hi wigglitz!

Any progress recording the brightness? I just ordered the same cam for the same purpose...

Could you post an image of your cam housing - or even better post the 3d printer file? :)
[Android Head-Units] thegametb:
I'm using USB and have mine as a front camera (front grill) for curb stops mainly. My car sits low. Using the default DVR app as well. Works beautifully. Found a weatherproof usb cam specifically for it too, since most dvr cams aren't weatherproof. I love it!
[Android Head-Units] Priknr1:
Any luck on a dvr function on the composite in yet?

I got a cam connected to it. When I select the AVIN on malaysk rom. I get the image of the front camera. But I am not able to use it for a DVR so far.

Did you have any luck?
[Android Head-Units] wigglitz:
No luck sorry :/

The cam I wanted to use for this kinda died and I gave up searching for a solution after that.
[Android Head-Units] nixfu:
I like the one that carjoying sells. I did not buy from them but have the same model.

https://www.carjoying.com/car-accessories/dvr-camera.html

It works great to attach to the back of your rear view mirror because of the shape of the body. I have mind there and the wires go up into the trim and you can't even see that it is there.
[Android Head-Units] llaugerm:
I installed that camera on my pumpkin 5.1 and I lost the audio in the Music app and Pandora. I installed the app IONROAD and that did not work well it keeps crashing because for reason it requires internet to work. I'll try this specific one from Pumpkin to see how it goes. http://www.ebay.com/itm/311374450638?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT

I'll take a look on that app for the DVR recording Caro.

[Android Head-Units] kopgil:
I connected a Logitech C910 webcam to my head unit instead of the crappy low-res camera that came with the unit.

Now I'm trying to find a decent app that will record in HD and save the files to an external SD card.

Autoboy works great, great video quality, but doesn't give me the option to record to the SD card, therefore it's useless for me.

CaroO doesn't seem to work at all with the C910, it connects to the OBD, but doesn't show the video (failed to initialize)

The stock Car Record app saves to the SD card, and sees the C910, but doesn't record in HD

Any suggestion for an app that will do what I want?
[Android Head-Units] Eozturk:
I have a Chinese Head unit which I also would like to use a front cam.

My rear camera works ok without any application. I have a seperate camera also. When I tried to install it by using the A/V RCA inputs the pre installed application does not recognize. My seperate camera is the same as my rear camera. It is not a USB camera.

Although I test the A/V RCA inputs the front camera does not appear on the unit.

The name of the application is DVR.

Do I always need a USB cam for an Android device ? (which means that I will not be able to use my seperate camera which is same as rear camera)
[Android Head-Units] BlackSprint:
I don't know, based on those details.

Mine is an MTCD device running Android 5.11 on RK3188, it uses the USB port for the front webcam.

I had a spare Logitech webcam lying about...plugged it and it worked first time.

Might be worth trying a few webcams before buying a specific one.

My Logitech is a higher resolution and a wider angle of view than the 'no-name' one on my PC, I think the angle of view is an important consideration for a DVR in a car.
[Android Head-Units] denekdne:
Mate...I think that You can make it by stock APP. Because I'm new on this forum, system/moderator don't let me put link here below 10 post here.

Try to put in google search: carjoying blog. When You are on it, search for this thread: "How to decompile the Car Recorder APK and changed the video resolution to 1920x1080 in HD on Joying android head unit car stereo navi system?"

There is a solution for Your case, I hope so :)

I have also ask You to check that your C910 will work with CaroO Pro app or AutoGuard Dash Cam - Blackbox app. Because I have Logitech C310(720p) and it work, but it's have poor quality and angle of view . I wanna change it for something better. Can You please check it for Me/Us?

P.S. for ALL... Guys.... You will not able (for now) to connect ANY AVin camera as a DVR recorder, because of android kernel. There is, on this forum many specialist that are able to explain Us why - with detalied info...

Many thanks for You and others,

Cheers

I have same this camera, its not that good, and the frame rate is really bad, I uploaded some samples previously
[Android Head-Units] sun.valeo:
Recommended for use in Android radios this camcorder. It is autonomous, does not use RAM, assembles and plays video on the screen recorder is a standalone flash memory. Excellent resolution. ;)

https://ru.aliexpress.com/item/1080...32342346688.html?spm=2114.13010608.0.0.VaZKI1
[Android Head-Units] mouscolo:
u sure its working plug and play? as far as I know the usb cam should have no buttons to work on android units, if so,,, can you show us some samples?
[Android Head-Units] sun.valeo:
Why use a USB camera ?! It is not convenient or practical.

1) USB Camera will consume a lot of memory!

2) USB Camera will consume a flash!

3) USB camera will use the front USB port!

These drawbacks are more than enough. With me the recommended camera you have a permanent record video and the ability to view any desired clip recording time on the Android screen!

I tried the camera out of your post. Not only that consumes a lot of memory, and terrible quality. My Android CarPad http://xdaforums.com/wiki/Newsmy_CarPad_NU3001

Sorry for my bad english.

https://youtu.be/njfFdXDBV24 ;)
[Android Head-Units] mouscolo:
so how you show from camera to to your screen? what parts u using, and hows the quality? and where it saves the clips?
[Android Head-Units] sun.valeo:
The captured video is stored on your own SD card. I am using 32GB.

You should understand that if the Android device comes with many applications for video just will not have enough RAM. For example running navigation, music and radio, e-mail, Bluetooth, and a lot more then.
[Android Head-Units] mouscolo:
so the unit used to view the stored clips on the SD u insert in the camera?
[Android Head-Units] sun.valeo:
Yes unit that you are using to view the video recording and set the DVR. Video recording is fully autonomous and without the participation of the unit. It is convenient and practical.
[Android Head-Units] mouscolo:
can u provide me with parts links to your setup?

and for sure deleting the files will be from the camera itself?
[Android Head-Units] sun.valeo:
The connection is not difficult, you figure it out.

What do you mean, I do not understand?
[Android Head-Units] mouscolo:
alright, I need to have same parts u using to buy them, if u can provide me with links?

and I mean controlling the clip files will be from the cameraor HU?
[Android Head-Units] sun.valeo:
I bought here https://ru.aliexpress.com/item/1080...32342346688.html?spm=2114.13010608.0.0.99cI55 full set, not buy anything unnecessary.

Videos are stored on the SD-card. Camera menu, select the item to delete a video or viewing. Video recording is done in the cycles of the entire size of the SD-card, video size is optional. You configure the camera while looking at the display unit and camera buttons.
[Android Head-Units] mouscolo:
thanks man, I really appreciate your help, gonna order one and see how things will go, what about night vision quality? can you upload some records samples plz?
[Android Head-Units] sun.valeo:
Example video recording - https://youtu.be/Mna-qszv27w

There generally poor lighting, almost one car headlights. - https://youtu.be/4UUAL__On9g

With good lighting at night - https://youtu.be/7YSRnAgohOk

During the day the camera shoots great. Not one of USB cameras, which I did not try to shoot like this. My opinion is the best option for Android.
[Android Head-Units] mouscolo:
its waaaaaaaaaaaaaaay better than mine, mine have bad quality in day and night, plus not wide screen, am gonna buy this one soon, do I need to use all connectors or DV-in is enough?

Hallo Guys.

I installed CaroO on my RK3188 with Android 5.1.1. CaroO dialogs perfectly with the ODBII. Recording with front dash cam to external SD works fine if i select in the options to save on files mode. But if i select "continuus mode" the result is an unredable movie.... all made of green sparkles....

Any idea what could it be?

Logitech c905

hi there,

I tried connecting my old Logitech c905 webcam to my car joying head unit but the unit is not detecting my webcam. I tried different apps as well and still no luck? The webcam is working on my laptop just fine so I know for sure its not the webcam.

Please help!!
[Android Head-Units] Quade & Cassidy etc.:
If your cam is not detected. try going into the factory settings of the android head unit first to confirm that the 'front cam' is ticked. use code 126. works for most joyings. or code m123456. then Apply, exit, reboot. try the canera then. good luck!

Hi people. I have strange problem. I have installed parking camera which is working great. Now, I have bought USB camera for front recording but not one app, except one who came with camera, does not recognize camera. I have tried CaroO, Autoboy and AutoGuard.

It like they are trying to use reverse parking camera. And reverse camera is activated on reversing only.

It is 5.1.1 Android headunit.

Any ideas?

hi all, I have read this thread and a hundred like it! I am still in need of a bit of help and XDA is obviously the best place to ask so here I am!

I have two main questions:

1. Desperately trying to get front driving camera working. I have a phono/RCA cam (like reverse cam) attached to windscreen. I can get it displayed in Aux In on the head unit, but not when connected into "DVR IN" which is the port I would expect to work with it best. Its an Android 4.4 DVD/Satnav double din unit which I bought direct from lightinthebox.com (great prices, ZERO support!). Would it be easier to set up using a USB camera?

2. I recently bought a newer Android 6.0 head unit which I don't need as the older one is better. However I broke the screen in it. I tested with the screen out of my other unit and its only the screen/touchpanel broken, it worked perfectly when I swapped screens. Does anyone know where a replacement screen panel can be bought?

Here is a pic of the screen -

Same problem here. car dvr only works with its buggy app on my allwinner r16. Did you solve this?
[Android Head-Units] vilo2:
Hello everyone

Risk, for lack of solution to my case, put a question here.

I have in my car a DVDPlayer (ISUDAR) that I bought some time ago. Adquisitorially a front camera . After installing the application that is in the camera's internal memory, I tried it and no image appears in the DVDPlayer. While recording (SD), immediately and continuously. I tried with the manufacturer or seller, solution for the case but nothing solved. The problem is that it does not recognize that it has a USB camera as USB.

Yesterday I tried the camera on my mobile phone (Samsung S6) and verified the following: If you use the cable that comes with the phone and that is used to connect the mobile phone to the computer, camera gives the same error (shown on DVD car), ie does not recognize a USB connected camera. But if I use an OTG cable everything is fine, good image, SD recording inserted in the camera itself, photos etc. Strange, is not it?

Can you help?
[Android Head-Units] BIGAndy1980:
Pardon my ignorance but I’m new to android. I have just purchased an Eonon headunit for my BMW. Loving it so far but I’m having a few issues with the dash cam.

1. Using the DVR programme that came pre installed the camera works but i can’t record. It keeps saying please mount storage device. I have an SD card inserted into the unit which I know is working as I have things being saved to it. Does anyone know how to mount a storage device.

2. I tried using Autoguard Dashcam. Everything works but the image seems to be mirrored and I cannot reverse it. Does anyone know how to do this. Also when trying to play the videos back on the unit it says video cannot be played.

3. I want to give CaroO Pro ago however I cant find it anywhere. Can someone point me in the right direction.

Thanks in Advance.

Hi guys,

Does anyone know what might be the problem when GPS signals lost immediately right after an usb camera plugged in?

The signals came back once the camera were unplugged. (the camera functioning fine, apart from not detecting gps as they're all lost)

Would it be a fault of the camera or the head unit itself?

USB thumbdrive works fine though, no issues.
