Hey Guys,

I have a Dopod 838 Pro and ive upgraded to all the blacks so far and atm have 3.5 aka Dymond... has anyone noticed that in none of the black releases the camera zoom works... is there a way around this? and also how the hell do u send a file (ie song or picture) via bluetooth?

Thanks

questions about black should be posted in the correct thread and ill give you a hint its not on this forum!

OK so I bought the Quad Core version non DVD version and here are the pictures. Right now I am using my bench power supply to power the unit.

Tried Airplay with iphone 6 after installing airpin, it works fine

Then I wanted to root it, used a few methods. Firstly I tried RootMaster 2.1.1 and framaroot, no go it does not root it. Then, use kingroot, unsucessful and reboot by itself. Lastly baidu root does seems to work properly.

I am at my wits end, how can I successfully root this unit? :crying::confused:

help pls.....

Other methods of rooting anyone?

[Android General] Alphas:
There is no USB cable that I can connect from the unit to the PC, unless the USB cable for the flash drive can be used to connect to PC?
[Android General] JPS11:
This thread has a lot of good information about these head units:

http://xdaforums.com/showthread.php?t=2660662

The suggestion is to use a pre-rooted kit kat rom that matches your processor and screen resolution.
[Android General] Alphas:
I read the thread but the method of rooting is not possible with this unit.
[Android General] JPS11:
​

From page 1 of the link:

Rooting only works for Android 4.2.2. If you want to root 4.4.x you need to take apart update.img and inject SuperUser app (this is only for experts as [MENTION=853627]coudu[/MENTION], [MENTION=3590033]Malaysk[/MENTION], [MENTION=6041319]dsa8310[/MENTION] ). The alternative is to install a 4.4.x pre-rooted image and you do not have to do anything.

My understanding is that the usual way of rooting does not work for Android 4.4.4. Unless you know how (I do not) to inject SuperUser into the rom, you should find a pre-rooted rom to install and then the device will be rooted. Since the quad core are new, I am having a hard time finding a quad core, 1024x600 rom for you. I do not know if a dual core, 800x480 rom would work.

I am not sure of your screen resolution.

There is a quad core 800x480 rom on the repository link on the first page.

I haven't found a quad core 1024x600 rom.
[Android General] Alphas:
I am looking at the rooted rom, the MCU MTCB-JY-v2.11 from lightinthebox is an older version of MCU from this unit, they are the same OEM.The resolution of this unit is 800x480, the problem is how should I change the rom when there is no reset button, no USB to connect to PC?
[Android General] ozzy lion:
Interesting, no way to boot into recovery? Not mentioned in the manual?

Maybe send the seller an email?

Another thought is that one of the rear USB ports may be an OTG port which means you could use a USB A to USB A cable to plug into your computer?

It actually looks very similar to the unit I ordered recently except mines only dual core and has some physical buttons on the front. The back looks identical. Mine looks to have a reset button though so hopefully shouldn't be too hard to flash.
[Android General] Alphas:
[YOUTUBE]MEPk6Cbe9q0[/YOUTUBE]

My version comes without the DVD loader, otherwise it is the exact same unit. I posted the message to them, hopefully they can instruct me on how to reset it.
[Android General] Alphas:
They posted the updated MCU and update.img on the website. http://www.carjoying.com/Joying-blog/12.html . But I am still waiting for them to show how to reset it. The MCU version v 2.49 is newer than HuiFei MCU in the repository, , so you guys can try to download it too.
[Android General] Alphas:
Finally got inside the bootloader, wow this unit does not have physical buttons, so they have two buttons holes for reset/move down and select!

Now that there is a update.img and mcu.img, what should I do to root this?

If your joying head unit android resolution is 800*480 and want to latest upgrade your stereo version is 4.4.4 kitkat like universal toyata android car stereo, please download the update file April,11,2015 in the link https://mega.co.nz/#!3s0QURxS!3icY8M03kqLgQwISOlZNbh7aJ_uSGArcFD83JRqvvGg
[Android General] ozzy lion:
glad you found it.

There is a video of a similar unit here showing how to reset.

[Android General] Alphas:
Unfortunately the reset button is position at another location, it is not exactly the same as the unit I had.

I am posting the high resolution images of the inside of the unit.
[Android General] Alphas:
Any idea how to do a backup without root access, I want to save the data in case of a bricked unit?
[Android General] Alphas:
I just do not want to brick it, to be sure there are two img files in the sd card.

update.img from quad-core rk3188 image, KLD, is in post #11499.

and mcu.img from http://www.carjoying.com/Joying-blog/12.html

reboot and update the img from sd right?

Since I do not have root access I cannot backup the system files.

Thanks.
[Android General] JPS11:
You do not need to update the MCU. You already have the same version.

The firmware from DSA8310 is correct.
[Android General] Alphas:
I got this rooted finally, you guys are a great help. One question, will the rooted image from joying quad core be uploaded too? I kinda like the interface from Joying rom better than KLD version. :D
[Android General] f(x):
Great looking unit. I like it how it has the sd slot right on the front.

What class is the Bluetooth on this unit?
[Android General] Alphas:
I think it should be bluetooth 3.0
[Android General] Alphas:
I check the chip is CSR BC6130, bluetooth v 2.1 EDR

[Android General] heps:
Hi, I've also bought this unit (but dual core with 1024 res) and I want to root it.

Could you elaborate the method how to do it? Thanks in advance!

I've also noticed some strictly rom-related problems. It is laggy because of some internal processes which are often hung but without root I can't remove them - one is CanBus service which is ready to read all info from the car (like torque, revs). I don't need this so it's pissing me off that some unneeded process is slowing down my unit...
[Android General] Alphas:
Do not root with the same rom with 800x480, the resolution is 1024x600 res firmware. If it is dual core, the link in #11378 or ask Malaysk if he has the version for quad core RK3188

I will not use the update though - I am afraid to brick the device.

There is no quality support from the manufacturer so I don't want to mess with it - especially when I managed to set all things up without root actually and I'm generally satisfied.

problem with the display of rear sensors

Have you tryed TOWELROOT ? https://towelroot.com/

I have the same unit , I haven't rooted it yet.

I'm facing a problem with the rear sensors. I only have 4 rear sensors to assist me for parking. But the in the display screen it splits those 4 rear sensors 2 on the front, 2 on the back of the representation of the car.

Is there a way any way (even beginning with rooting my unit) to set this right ?

[Android General] rapid_rabbit:
I'm planning to get similar device (1024x600, rk3188 - http://bit.ly/1KiLBW6 ) just specific for ford. Can you share your opinion about it - does it work smoothly, how is the sound, bluetooth, screen sensitive enough, etc?

Why do you root it (apart from moving apps to SD) ? I have plenty of rooted tablets and phones and not sure if i need to root this one, don't plan flashing custom rom, kernels etc ?
[Android General] erkme73:
Agreed. I just flashed the same file and no root. Sucks too, since it wiped everything out. Wouldn't mind as much if I actually got root. Maybe all we got was a virus?
[Android General] Dbeayon:
A virus? That's a bit of a stretch now. Let's see what Soeme says. I applied his May file that he last updated and it rooted the device as expected. As shocking as this may sound, he might have just uploaded the wrong file.

BTW [MENTION=846630]Dbeayon[/MENTION], we both have the same unit. Since I now have a wiped OS, I'm going to roll back to the May release to at least have root.

It does beg the question, how does one install TWRP or other recovery on these? It would be great to be able to do a nandroid...
[Android General] erkme73:
After going through the 1000 pages, I found for our JY units the following:

July rom (rooted with xposed and other goodies): http://xdaforums.com/showpost.php?p=60591423&postcount=12068

I just flashed both, and it works like a champ. The data partition has been expanded to 2GB so installing apps doesn't run into the limit seen with the stock rom. I haven't had time to play with it much, but it comes with Titanium, ES file explorer, Root Explorer and a bunch of other customizing options under the main system options. Really worth a look.

Hello All and dear Developers

This device is amazing, no only for classic users like universal and stable device, but for a bit advanced users it's no only the DVD or Radio. It's really toy !!!!!!

Can I have question for developers ?

I've rooted my device with update_4_4_4_1024X600_6_RK3188_MAL_NEXT_LAUNCHER_13_08_2015 and a lot of a new functions are crazy :) Amazing :) Now I'm testing a connection the DVR camera and I have question about DVR applications.

My question:

The Integrated application inside andriod "Car Recording" doesn't have any options for the settings of recording like resolution and another parameters, exist any way for manulally edit some a file like .xml or another or where can I change it ?

A'm not big specialist for andriod

If this manually change isn't possible can I disable using the USB port from the side integrated app "Car Recording" for choice install another simiar Recording application. Why ?

When I tried install another similar USB DVR appication, the device port for the camera was busy and a new application couldn't open this device of my camera.

Now I'm testing HD DVR camera Logitech C902 which has a good parameters and I would like tray higher resoltuion for recording. Now is resolituon set to 640x480. And in the documentation from Logitech for this product is wrote this:

***************************************************************************

Recommended requirements for full HD 1080p and 720p video calling*:

1 Mbps upload/download for 720p

2 Mbps upload/download for 1080p

****************************************************************************

It means that for USB 2.0 according data flow in practical capacity around 280 Mbit/s , which has this Quad Core Android 4.4.4 kitkat Head Unit Car Stereo Radio

should be possible use higher resolution :)

For a saving of video files i'm using SSD 250GB HDD on the port External_USB2

Re: I use Caroo which just so happen they made a fix for just for our units.

I do not miss the DVD, you have 2 USB ports and the microSD ports on front, very easy to just put movies into avi format and play from the cards. It does not come with a remote. I only use it when sitting in the driver seat so this does not bother me. As far as the ccameras - it only has 1 camera port by RCA jack. You can attach another camera by USB.

Oh, If any one is installing it in to Nissan/Infinity cars that has Bose sound system.

Easy rooting Pure Android 4.4.4 for Joying

Hey everyone. I understand that this thread is little old. I bought the RK3188 800x480, 16 GB flash model. (I can't post the link of the product right now)

When I was not able to root it with KingRoot, Towelroot, Framaroot etc. I had left with only one option to root it with the help of PC (either use any application to flash the rooted image or flash the image by myself).

But I found a way to root it in a very very simple way. It worked for the device I bought. I hope the same may work for all other Joying devices.

Go to settings -> Factory settings -> enter *#hct#root# at the prompt and hit OK. You will be temporarily rooted. To make this root permanent, install SuperSU.

Hi - sorry if this is not an appropriate question, but i want to see if anyone else has the problem. I have a joying head unit 4.4.4. One feature is to extend the "standby" time after the car is off, before the unit powers down and reboots on start. however, it turns out that while on standby, ***the unit interferes with the remote car entry, and the remote keys won't work unless right up against the keyless entry receiver in the rear pillar*** Cost me about $600 worth of Toyota diagnosis and parts to find that out!!
[Android General] rushtoshankar:
Hi pwb001, I have faced the same issue in my Hyundai Sonata 2003. I did find the difference on the same day I installed the unit. I figured out that the unit was the cause. I initially thought that the unit was drawing more current from battery, hence the remote entry (especially lock, I haven't tried opening) didn't work properly. But I noticed all the lights on the door, on the roof are glowing fine. But didn't realize that the unit may interfere with the signal. I will let you know if I find something.

Did you install the GPS antenna, wired the external MIC?
