Btw, "ro.kernel.qemu=1" tells Android that it's running in an emulator and that's why its so sluggish. However, this also allows adbd (Android Debug Bridge Daemon) to run as root.

I'm not sure what is on that port. But, it is only listening to port 5037 for the loopback address; 127.0.0.1. If it were listening in on any port, it would be 0.0.0.0:5037
[Android Head-Units] WonderEkin:
The port should be 5555

The adb wifi button runs the following command under system uid

stop adbd
setprop service.adb.tcp.port 5555
start adbd
[Android Head-Units] bmj67:
adb devices in terminal explorer will not list the radio. i am assuming that is why adb will not connect

Thank you for your interest in this not so popular device.

Add service.adb.tcp.port=5555 into /data/local.prop

re-run the app, reboot and try adb it

if not working, pls execute "ps | grep adbd" in terminal, i would like to know if the adb daemon is running or not

I guess the best way to check if it stuck is if he executed, "getprop | grep adb".

Root Checker is checking for the su executable, which is not installed yet. WonderEkin's masterkey exploit is using SettingsProvider.apk that you provided. So, the modded APK can only exploit access under the system id. This is why it is still necessary to use adb to remount /system as read-write then push and chown the su binary to get root access.

Install & Run the app, click Step 1, reboot and click Step 2. The device should rooted

https://drive.google.com/file/d/0BwKObTKUOwAqOWN5cUdXZnNjejg/edit?usp=sharing

If Step 2 didn't work, do it manually

1) download the attachment, extract and push the su to /data/local/tmp

adb push su /data/local/tmp/su

2) Run the following code in adb shell

mount -orw,remount /system
cat /data/local/tmp/su > /system/xbin/su
chown 0.0 /system/xbin/su
chmod 6755 /system/xbin/su
mount -oro,remount /system

3) Install Superuser app

To reset ro.kernel.qemu, simple delete /data/local.build

How to Root the Pure Android 4.1 Car Stereo Double Din Unit

I have got an Android 4.1 Car Stereo Double Din Unit.

The same as mentioned in post # 318 http://xdaforums.com/showpost.php?p=48361161&postcount=318

i got it from here: http://www.aliexpress.com/item/Capa...al-2din-Car-DVD-GPS-Player-3G/1527375719.html

[Android Head-Units] guano30:
Hello!

I just also have one of these 6.2" 4.1 Android Car DVD units.

Root and else works like a charm, thank you for the help here in that Thread.

I am looking for Solutions for some things.

1. If my S4 is connected via Bluetooth there is no Signal Bar shown at the Unit, its always emtpy. Is that normal, coz this Bar only works if a 3G Dongle is added?

2. I have a Huawei E169 3G Dongle. I disabled already Autostart via Terminal and from Time to Time i can see some Bars shown at the Unit.

Also in Mobile Settings i can see APN Settings but if i try to search a Network it stops in a few Seconds by Error.

But okay, maybe my Dongle isnt compatible.

3. If i have a compatible Dongle what happens? I recognize that there is no Phone app at the Unit. Only the Bluetooth Phone.

If the Unit has a valid 3G Dongle the Phone app Icon apears?
[Android Head-Units] kschumake83:
1. Yes, the signal icon looks like an empty triangle if you don't have a compatible 3g dongle in.

2. I can't help you here as I just tether off of my phone.

3. No, The unit will still be like a tablet and you wont be able to make and receive phone calls without a phone, or some hacking to install things to make a true phone app work.
[Android Head-Units] uid65252:
I have not yet tested Bluetooth.

I have 4piece of 3G Dongle, but only Huawei E173 operates on my HU.

The HU does not operate as a phone, only Data connection is possible with 3G Dongle
[Android Head-Units] guano30:
Oh ty guys....

So buying a 3G Dongle is wasted Money as long its not possible to make Phonecalls.

I will use my S4 for tether.

Somebody know an app which is able to show Signal bar of my S4 paird with BT at the HU?

EDIT:

Next Problem seem to be the build in Mic or the Mic Jack.

The Build in Mic is crap as far people tell me if i am talking to them or phone.

I plugged in a 3.5 Mic from my old Parrot BT Unit which works pretty well with that.

But at the HU plugged in its still same, like the external Mic is not working

Somebody has same issues?
[Android Head-Units] sciallo:
Where did you plug that in?

Are you one of the few that have an external mic. connection in the back?

(some more on that in this thread starting at #27 and then some.)

For most of us that don't have those, it involves soldering an external mic jack to the pads shown in that picture (or as suggested by some cutting those wires and connecting to those to avoid having to solder on pads)...

Some units came with a mic. plug in the harness, trinig to connect to the same pins on a unit that didn't come with it doesn't work and the reason is explained in that thread...
[Android Head-Units] guano30:
Yes my Unit has Mic in Harness, look....

But as now it dont seem to work.....

I dont know if i can switch from build in to external Mic.
[Android Head-Units] sciallo:
Cool, then it should work...
[MENTION=2678656]ThePapabear[/MENTION] has that too and I think he had no problem... Not sure what mic. he used. Short of getting to the board and looking to see if you have this pad (R131) populated I wouldn't know what to tell you...

---------- Post added at 01:12 PM ---------- Previous post was at 01:11 PM ----------

Do you have any other mic. you can try? maybe a computer mic?

---------- Post added at 01:17 PM ---------- Previous post was at 01:12 PM ----------

BTW, that would be cool, I'd like that too if anyone knows of a solution...

Didn't want that question to go lost in the mix :)
[Android Head-Units] guano30:
Now i tried an other Mic and yes, it works.

But sound still not that good.

I think Problem is, that now both Mics work, the external and the build in........

If both work the impedance is to high and sound getting low........

Jesus, i really want to make Phonecalls with that Unit if i build it in my Car. But at the Moment its pretty worse Quality......

Do i really have to cut internal Mic to get better results?
[Android Head-Units] sciallo:
Well, I did raise that question in the hardware thread thanks for confirming my suspicions. Although according to [MENTION=2678656]ThePapabear[/MENTION] connecting a mic, did exclude the built in one (I couldn't see how following traces on my mic-less board...)

Since we have started a hardware thread and this one is pushing some good amount of pages, should we take the conversation there maybe?
[Android Head-Units] guano30:
sure!

In my opinion one of the biggest issues at XDA not to make several Threads to several Topics.

If you are new at this Unit and have to read about 180 Pages first its pretty frustrating
[Android Head-Units] sciallo:
Yeah, that's why I started that tread, to try and separate at least software/hardware I have a hard time finding information I know I saw in a 200 page thread... Also I pushed to start putting verified information on the wiki page for the same reason. Much more to put there, but it's a start...

I have been thinking about getting a AN-21 U Unit for a few weeks now, they seem far from optimal, but quite good for the price. The only thing that is a dealbreaker for me was the internal mic, and I could not find a good unit with external mic support. But since that seems to be solvable (see hardware thread, I am on the brink of getting THIS unit.

I contacted the seller with a few questions, where one stands out: He claims the screen has 1280*800 screen resolution rather than 800*480. It says that 1280*800 will be added "next year", but the product description clearly states it has 800*480.

See for yourself:

[Android Head-Units] p64imp:
Which one to get?

What do you guys think between these 2:

http://www.aliexpress.com/item/Capa...al-2din-Car-DVD-GPS-Player-3G/1527375719.html

http://www.aliexpress.com/item/Andr...er-GPS-Navigation-audio-Radio/1570938341.html

The seller verified for me on the $276 model that it supports PIP just as the first one specifies, said he'd throw in the wifi dongle, and that its indeed the dual core 4.1 android os version unit.

He said:

"Yes, it has Picture in Picture and it has Wifi function, we will provide free wifi adapter!

This unit has A9 Dual core, we have a wrong description of the name, but it is True A9 Dual Core processor.

AS we are factory directly, so our price is very so low!"

I'm just a little skeptical by the vast price differences, though to me it looks like they are the same unit. Plus the 2nd link seller also is throwing in the camera which the first seller isn't, though for piece of mind i'm not sure its worth an additional $140...

One prime difference after talking with the seller is he states the usb only supports a 32gb max usb hard drive? :

"It can not support 2TB hard drive, only up to 32GB USB, and wifi is external wifi dongle, free included"

Seems odd... do some units only support 32gb where others support 2000gb as the first seller claims?

I'm just trying to play it as safe as possible... when something sounds too good to be true, it usually is.

Advice here is very welcome!

---------- Post added at 10:10 PM ---------- Previous post was at 10:00 PM ----------

Heh, see my post above. looks like we are working at the same unit. Please report to me your findings and i'll do the same. as i said above, he told me the usb only supports 32gb. Also odd that his answer as to why the unit is so cheap varied... told me he's selling directly from the factory, told you its on super sale. also the mixed feedbacks stating nothing but "Excellent!' are so scattered over these units... perhaps fake feedback? -_-

and this one only has one feedback of "excellent!" makes me speculate if it's legit. This is why i'm considering the $450 auction instead. at least that seller has a lot of feedback and a poster earlier in this thread bought one from him so you can tell from user experience here on this forum that you wont get scammed...
[Android Head-Units] donaldta:
You can always ask the reseller to install Android System Info. Then have them email you output from using the system tab and then "export system infos" from the application (overflow) menu. There will be a file saved to /mnt/sdcard/AndroidSystemInfo directory.

Then you can verify the processor and the display resolution from the output. KID52 posted the output of his in Post #129 if you want to get an idea what to expect.
[Android Head-Units] sciallo:
I might be confused or way off, but I thought the only units that came with PIP where the non-pure win-ce based ones... Or am I understanding PIP wrong?
[Android Head-Units] fcortes626:
I got my replacement unit today. this one came with igo pre installed and not sygic. i might uninstall it and install sygic because igo looks too simple. Anyone know of a music player that will read the music from my external 1tb hdd? i tried playerpro but it only reads from the internal sdcard.
[Android Head-Units] donaldta:
Use FolderMount [ROOT] to mount the the folder with your music from the 1 TB HDD onto /mnt/sdcard/Music directory and it should be able to be played by most 3rd party media players.

---------- Post added at 04:30 PM ---------- Previous post was at 04:27 PM ----------

I don't think it matters. Since the video inputs are connected to the MCU board, it could just be a feature of the MCU to overlay a PIP window that nobody has explored yet.
[Android Head-Units] sciallo:
Makes sense, different MCU or simply another "built in app" Could be interesting to explore that, and I would mess with yet another MCU file... lol
[Android Head-Units] PsychoMcSatan:
I tried a few players and ended up with N7 - https://play.google.com/store/apps/details?id=com.n7mobile.nplayer&hl=en

I had fiddled with Folder Mount and other players, but it seemed sometimes it would take a while to create the mapping and the player would start up not seeing anything.

This N7 player doesn't need it as it allows you to choose a specific folder for your mp3 library. I'm rooted which I'm guessing is necessary to see the external card or hdd.

What I really like with this player is that it presents all your album covers scattered across your screen which you can zoom in and and out with multitouch. Still not the safest thing to be doing while driving, but it does make it easier to find a particular album than scrolling through a list.
[Android Head-Units] kschumake83:
I don't know if it will read the HD, but the one I used until someone pointed out how to get play music working was rocket player. I liked it better than the f'd up writing that n7 displays the artists in.
[Android Head-Units] fcortes626:
i tried it and its ok but alot of my music doesnt have album art so its hard to find my music.

seemed to work for hte stock music app but not for playerpro. how would you undo the filemount? it didnt sync completely so all my music doesnt show and some are corrupted.

ill try that one too.
[Android Head-Units] guano30:
HI!

If i try to do that on my Unit i get an Error Message in Shell "sh: grep: not found"

Any Idea why?

Is the grep Command missing on the Units?
[Android Head-Units] donaldta:
Hold down the name of the pair that you created and then press the garbage icon.

Not all distributions come with the all Linux commands. Try installing Busybox using a Smart install to prevent a conflict with the current commands that are already included.
[Android Head-Units] ransu:
Im considering cutting the internal mic wires also. My unit doesnt have the mic output listed on the sticker on top, but I have a pioneer mic off crutchfield for $20 connected to where the one guy's post way back said the mic goes in. Just relocated one of the output's pins I wasnt using to do it. Sounds more full and clear when doing a voice recording. Only problem, both mics are working like you said.

QUESTION

QUESTION

They seem to be unable to answer simple questions... This is really annoying (but other sellers do that too, I've tried multiple ones).

I don't think I will get an answer (or screenshots) for my last question. Are there even screens with 1000*800? Seriously, this is very new to me, even 1024*800 seems odd.
[Android Head-Units] chris.r.r:
I would be really careful if the seller is already unable to answer those simple questions... Doesn't seem to be very trustable.

I've also heard about the 1024x600 pixels for the AN-21U. This store offered our unit with that resolution before christmas:

http://www.aliexpress.com/store/group/Car-DVD-R-Series-Pure-Android-4-1-1/426795_253539039.html

But they removed 1024x600 again from the specs. Maybe because it's simply not deliverable at the moment?

I think for our unit only a 16:9 aspect ratio (or almost 16:9) is possible. Everything else should change the device's frontplate design, right?

Nevertheless, if a seller seriously claims for 1000x800 (that's not even 4:3) or even 100*800, he obviously has no idea what he is talking about ;)
[Android Head-Units] guano30:
Maybe an insane Idea, but would it help to destroy the build in Mic by using a needle and puhing it into that small Hole of the Mic?

Silly Idea i know.....

I guess the only way to get a good Sound for making Phonecalls is to cut off the build in Mic........

Coz if 2 Mics running the resistance of both Mics is too high what causes a too low Noise........
[Android Head-Units] Matt Kirby:
Regarding resolution:

I bought an 8" version, current listing shows a resolution of 800*480 - which I've confirmed with Android System Info is what is actually in the system (sorry, I can't post links, I've got less than 10 posts on XDA!).

However, the listing when I purchased said the resolution was 1024*600 (I can still view a snapshot of the listing at the point of sale).

So, I doubt that there is a unit out there with a resolution higher than 800*480. My only guess is that the graphics chip might be able to output a higher resolution to other displays, but the physical display in the unit is 800*480. When creating the listing they've probably just picked the higher resolution from the chipset rather than the display.

Having said all of that I'm happy with the display itself - it looks good and is responsive.
[Android Head-Units] sciallo:
These guys are just resellers, I doubt they stock all miodels of the units they sell, when I bought mine, it got drop-shipped directly from tonghai create. I don't think they have that one to install something on and send you screenshots... They might convince the manufacturer to do so, but that will take them a few days once the factory reopens and catches back up after the Chinese new year holliday...

The unit is easy enough to open, I don't know if I'd be poking in there with a needle...

Btw, Resistance is too LOW...

the mics. are connected in parallel.

Nova Launcher

Hi

Just looking at your screenshot. I too am using Nova Launcher Prime, cannot get it to fill the screen (massive borders either side where I cannot place icons). App tray fills the screen, but widgets/icons on the homescreen do not. What grid size are you using for the home screen? Also, what clock/weather app are you are using?

When I enable the app-tray in nova, I cannot get it to sit at the bottom of the screen, it wants to sit on the right hand side. Any way to change this.I use Nova on 2 other devices - I am suspecting its the hardware/firmware + Nova effecting the borders and app-tray.

Nigel
[Android Head-Units] guano30:
...well ok......

to reach the Mic its really simple. Only to remove the 4 Screws at the Display and you are already where you want.

I solder off the 2 Wires of the build in Mic.

The Sound now is better but still too low. I have to go pretty close to the Mic to get understood.

I tested 2 Mics, one from my old Parrot CK 3100 and one of my JVC Car Stereo.

Both not loud enough.

So how we can boost the external Mic? Sadly no Settings to increase Volume of the Mic :(

Any Ideas?
[Android Head-Units] p64imp:
I got the same answer from him:

my question:

Jason,

While i'm awaiting a reply for this question:

32gb only from USB? i thought 32gb max was from the micro sd card. Why is the other seller claiming usb (hard drive) can support 2000gb and your's cant?

I'd also like to know if this unit is a 1280x800 resolution screen. I was speaking with another user interested in this unit and he told me you said it is a 1280x800 unit. Please let me know on both questions

his answer:

Dear friend

it can not support such big USB hard drive.

and it is 1000*800 resolution!

Jason

Are there really units out there that only support 32gb jump drives via usb and nothing greater???? If so, what is the point of that??? seriously...

This guy:

http://www.aliexpress.com/item/Andr...er-GPS-Navigation-audio-Radio/1570938341.html

sounds way too suspicious.

maybe i should just go with the other guy instead:

http://www.aliexpress.com/item/Capa...al-2din-Car-DVD-GPS-Player-3G/1527375719.html

however i sent him a question day before yesterday and have yet to receive a response. At least the cheaper dude that seems to know nothing replies right away...

What do you all think? Possibly he's legit but just clueless about the USB support capabilities and screen resolution of what he's selling? Price is unreal for the unit. so many red flags...

another item i'm considering is, if he's so clueless about the usb support and resolution, perhaps he's also wrong about the android OS version and the processor type/screen/w/e else as well... hmmm

I sent him this:

so you can confirm it is only 32gb max on the usb connection? That is 1/2 of what my jump drive currently supports. thats really tiny and pointless...

also, there's no such thing as 1000*800 resolution to my understanding which confuses me. that's not even 4:3 aspect ratio. All this sounds a little odd to me frankly. Do you have some way to confirm these specs?

and will post his reply when i receive it.
[Android Head-Units] chris.r.r:
hmmm, that's odd. I hoped that this issue is sorted out with attaching an external mic.

However, I've also thought about boosting/amplifying the mic. There are several solutions for Android out there, but I'm afraid that the mic input is handled on MCU side. That means, that if the MCU driver in Android doesn't offer an interface (like via settings) we won't be able to control it. Am I right?
[Android Head-Units] guano30:
I installed Busybox now and yes, grep works.
