Just for comparison sake, at 24000 that's somewhere around where a Galaxy S4 is, give or take a bit. The Rk3188 should be somewhere in the 13000 - 17000 range.

Let me know how you make out and also if you come across any apps that will decode Digital Transmissions p25 or Motorola DMR ,Icom or Yaesu digital modes ..that's what I'm looking for now...
[MTCD  Android Head Units Q&A] nixfu:
As far as I know those are Windows or regular Linux only right now. I guess it might be possible to port the Linux over to android, but I don't think the developers have ever considered doing it yet. Also, having played with those programs like DSD, they are very CPU intensive since they do it all in software and I kinda doubt the head unit has nearly the proper performance to do it.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
i have never used DSD but i think that would be the type of thing i would be looking for ...it would be great if someone could port that over ..or similar app... as far as processor power the radios are compatible already with DVB-T dongle and DAB+ radio (thats a digital transmission ..right?? ) android systems are receiving those broadcasts wouldn't it be similar? ....http://xdaforums.com/android-auto/mtcb-hardware-development/adding-dab-functionality-t3208344

youtube has some videos of these head units working with DAB+ it looks cool and seem to work well...so my thinking is you should be able to make it work with other digital modes ..like the modes listed on the DSD wiki ..and digital broadcast hdtv

thanks for the comparison :D

i had no idea if my benchmark was good or bad or how it stacked up with other android units
[MTCD  Android Head Units Q&A] Cid6.7:
I hope you dont have any issues with your unit.

I bought from him not even a full month ago. Since then my wifi went out on me it wouldnt connect @ all & I sent the seller like 20 messages over Aliexpress. I threatened to open a dispute then out of the blue he started responding to my messages. He suggested I update the MCU & firmware with a zip file he sent to me. I did & it didnt fix the wifi issue @ all it was late @ night so I went to shut the car off & head in.. The unit wouldnt shut off thinking it would kill my battery I pulled the power to the unit. That was the last time I had it powered on. He told me to jump key2 wire to ground & try to get it to boot to recovery & nothing happened. He told me to order another unit (for faster shipping time) & he would refund me the $$ when he got this unit back. Shipping this back is over $65 canadian plus the other unit he wanted me to buy $230 plus the $230 I already threw in the trash when I bought this one..

Theres no guarantee he would refund me the $$ once he got it back so I'm stuck with a completely dead useless unit.. I'm not only pissed @ him but this was a gift to my son for his 17th Birthday. I cut the bezel in his car for this to fit as well..

I hope you have a better experience with him than I did..
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
thats sux....are you sure 100% it was the same as mine because in mine the wifi is part of the intel board.. was the wifi still able to turn on and off .i could see maybe a bad antenna connection off the board...did you try a different antenna ..the stock antenna is no good and in my truck i had to do some mods to make the unit fit without the wifi antenna getting crushed by my firewall and wire harness...so far so good with mine..... if your 100% sure you Have The same model 2gb ram intel cpu and it look like the one in my first post pictures in this thread IF YOUR 100% sure can you please upload the firmware he sent you .if you didnt send back yet maybe someone on this thread can help you out and get this unit restored and working i wouldnt think that on chip wifi would fail but the unit would still function ..were you able to get to recovery screen ..also did you root or flash any other roms ..... i hope mine does not have the same fate as yours but i guess only time will tell..so far so good with mine its working fine
[MTCD  Android Head Units Q&A] Cid6.7:
Sorry I should have mentioned this in my post.

No mine was the 1gb model, I just saw who you bought it from & went on a bit of a rant.. lol

BTW Since you removed the top of the unit you've most likely voided any warranty it came with.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
i would have never sent it back to china anyway ..

i would ckeck the antenna connections and does you wifi turn on and off like when it worked
[MTCD  Android Head Units Q&A] Cid6.7:
I checked the connection coming from the back after everything went to ****e. And yes the porcelain piece inside was too far inside the brass casing so the male pin could hardly contact.

But now it does nothing doesn't turn on @ all & is sitting partly disassembled on my bench.. Notice the white goop on the connections that you can take apart. At 1st I thought it was glue to hold them in securely. But what it is, is to let them know if you've been in there messin with the inards. If that "glue" is separated from where it is now they know you've messed with it & voids your warranty..lol Tricky tricky
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
does the inside it look like the pics i posted

take some pics of the unit and post them here i would like to see what your talking about.And maybe someone will have some insight and help you get it running again
[MTCD  Android Head Units Q&A] Cid6.7:
I just took board out its not a "intel" chip it has the Quad-Core Cortex A9 I think
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
the insides dont look like mine ...but i would reassemble and lets see if we can get it to boot
[MTCD  Android Head Units Q&A] Cid6.7:
Did yours come with that wifi antenna ?

---------- Post added at 04:11 PM ---------- Previous post was at 03:55 PM ----------

I cant see anything that looks burnt inside sometimes theres a small hole on the top of a resistor or something thats popped but I cant see anything like that. But man the welders that soldered this thing together need practice lol
[MTCD  Android Head Units Q&A] ikerg:
Looking to the update.zip for rooting for mtcd Intel units it is based on old boot.img (kernel and settings from September) and last update (December) resulted in changes in some settings for video and some drivers changed.

If using update.zip for rooting over a ROm from December will cause to revert the settings and drivers to the September state.

I am planning to release an updated file based on the most recent boot.img file from December rom

I would love to test out the rom, I have a 135n2 unit to test with. Was it you or someone else that was going to change the SRC button function as well? Because I would love for it to be a play/pause button because I have a canbus adapter I can't relearn any of the keys
[MTCD  Android Head Units Q&A] sonof:
Can't you remap the buttons when you are rooted?
[MTCD  Android Head Units Q&A] vassandrei:
Maybe.. I am rooted! Could you tell me how?
[MTCD  Android Head Units Q&A] sonof:
Unfortunately I don't know.

Anyone know how to remap the hardware buttons?

gustden here remapped SRC key but do all of them require modifying APK's to change the behavior?

Edit: I'm hoping MTCD tools works with our unit.

Edit2: Just tested and it does not work :(

I have non-functioning DVD and EJECT buttons on my HU and the seller doesn't provide any way to make use of them.
[MTCD  Android Head Units Q&A] avenant:
Does anyone know if there is some service which is responsible for the "mode" wheel key button, which lets you cycle through apps? when you press mode on wheel key button, it cycles through the 4 factory apps, Radio, Music, AVIN and Video, however if you use MTCDTools, you can add your own apps to cycle through, so in my case I can cycle through 7 apps now, but I want to disable the factory apps you can cycle through like: Radio, Music, AVIN and Video...

There is this app lets you disable services: https://play.google.com/store/apps/details?id=cn.wq.disableservice

Perhaps with this app it is possible to disable the service which cycles through the factory apps? Or is the software that is responsible for the mode button behavior not a service?
[MTCD  Android Head Units Q&A] sonof:
How to root for dummies, please.

I tried three different methods and failed each.

Update.zip was on SD card. Nothing happens when inserted. Rebooted while inserted and recovery flashed briefly (I had to touch nothing) and then it took 18 minutes to boot but SuperSU says no root.

ADB over WiFi with install.bat was able to connect but gave some errors although it said to reboot device. Still no root with SuperSU.

Manual copy of boot.img etc. with ADB over WiFi also failed. Some error message about connection while copying files although it first got connection just fine.

Try the rk3188 headunit app from the play store

I had same issue with the install.bat from the joying forum.

go to http://adbshell.com/downloads and download "adb kit" and replace those files in your folder.
[MTCD  Android Head Units Q&A] ikerg:
You were using an update.zip for mtcd intel based units...So it wont work for your unit.

Joying and mtcd have different mcu and the ROM is structured in a different way.

[MTCD  Android Head Units Q&A] vassandrei:
has anyone tried installing xposed framework for the intel joying head units? like through flash fire or something? the sdk22 version 87 latest one. Does it work?
[MTCD  Android Head Units Q&A] joshnat:
The problem is that if you try it and you are unable to boot, there's no way to get to recovery to fix it. So I don't think anyone has been willing to take the risk.
[MTCD  Android Head Units Q&A] vinhZ:
Also there has been some reports that some xposed Modules are causing intel chipsets phones to crash and bootloop.
[MTCD  Android Head Units Q&A] vassandrei:
Wait, is it only a soft brick? Because then if you put a firmware update on a usb or something and then while rebooting hold the power button it will force a "recovery" update. I messed up an xposed install one time by doing the wrong SDK framework (I think..) and it was stuck at the "android" logo without booting.
[MTCD  Android Head Units Q&A] joshnat:
I didn't know you could do that on the joying Intel units. I'll play with it and see what I get.
[MTCD  Android Head Units Q&A] vassandrei:
Just in case I'll mess around with it one more time tomorrow, don't do stuff yet, maybe I just got lucky or something... but the way I understood it is that the "recovery" just automatically flashes whatever is on the USB or SD, assuming the folder and file structure is what it expects.

Anyway the way I did it is I held the power/volume knob for almost 30 seconds or so until it started doing a firmware update procedure
[MTCD  Android Head Units Q&A] dcman008:
If this is true, this will change a lot and I think more people, my self included will be wiling to take some more risks.

Any one leave the sd card with update files in the slot after doing an update? If so did it start the process over again?
[MTCD  Android Head Units Q&A] avenant:
I did, when android is booted, it just detects there is an update file, and asks if you want to update or not... it doesn't force an update, it just asks if you want to update or not, same happens when android is already running and for example you copy/move the update.zip from a folder to the root of the sd card, then it detects the update.zip and asks if you want to update or not.

did you manage to install xposed and got it working?
[MTCD  Android Head Units Q&A] sonof:
I did recover from endless Android logo (resulting from trying to root with Joying HU root.zip found in this thread).

I did the following:

Put latest Joying update files to microSD card and insert it to GPS slot. Press and hold both reset and power buttons. Once it boots continue holding reset button.

This lead to automatic install of Joying update files and my HU was back alive but I hate the Joying company for not providing means to enter recovery and a complete ROM.

Edit: For me it did not ask if I want to update or not. It just began updating automatically. In contradict to the post above. But I was unable to boot to Android when I tried this.
[MTCD  Android Head Units Q&A] vassandrei:
So I tried to install the framework with flashfire, nothing really happened. xposed installer doesn't detect an installed framework. I'm gonna try installing with flashify instead tonight.. (I have a feeling there won't be a difference) but there was no lock-up at boot this time.. I think we do need a proper recovery like twrp, and I think maybe with a proper USB connection we can boot one on-the-fly in fastboot, which we can't do over wi-fi
[MTCD  Android Head Units Q&A] aneesp:
Good to hear that you could manage a force update this way.

But what you mean by "But I was unable to boot to Android when I tried this" in the last line of your post? Couldn't you boot properly after completing this method for force update? Has any one tried this method to reconfirm if this works for JY135N2?
[MTCD  Android Head Units Q&A] sonof:
Sorry I was referring to the other poster that said he was asked if he wanted to update or not. I wasn't asked and I think that was because I was unable to boot past first Android logo.

So after force update I am able to boot properly and everything is working as good as new.
[MTCD  Android Head Units Q&A] avenant:
which version of xposed are you trying to install? because the normal version will never work...

[MTCD  Android Head Units Q&A] Xaadi316:
How-To install:

1. You need a Windows PC that is connected to the same WiFi network as your HU.

2. Unzip the attached file somewhere to your disk.

3. Run CMD.exe as Administrator

4. Change directory to the folder that you unzipped.

5. Run the install.bat script with an IP address of your HU as a parameter, for ex.:

C:\Users\<username>\Downloads\Joying_JY-UL135N2_SuperSU> install.bat 192.168.123.137

6. Wait until script finishes and reboot your Head Unit.

7. DONE!

You should now have the SuperSU application working.

I am having trouble getting tasker to work on this unit. If I launch it it works, but that is not the point. It is supposed to launch on its own when the unit boots. However the unit only goes to sleep. Im guessing that there is a task killer built in to keep programs from running like this.
