Why was it a mistake DSA ?

Klyde tell me that the Easy Connected app requires USB OTG on the phone, that is, it requires the phone to be able to supply power to a USB device, my Find5 does not have this feature (although it can be added with a custom kernel and a USB y-lead), so this is why I get a message saying that my phone is not compatible. This may be why people are having difficulty with it ?

I think DSA is saying he regrets making a hybrid ROM, not rooting JY ROMs in general, I think he will root a JY 1024x600 ROM if it becomes available, if I m wrong, I m sure DSA will correct me.

All of the launchers are on the fileserver, so anyone can change their launcher and for instance, install a KLD ROM and the KGL launcher, after which their device will look like it is running the KGL ROM.

You do have experience with Linux - Android IS Linux !

Ah, I see.

Do you install the app ? If nothing happens then you have no launcher ? !

In "firmware", the ones from March onwards are DSA's ROMs, plus they are also in the thread from the last few days.
[MTCB Android Head Units Q&A] RaZi3L_:
I completely understand your opinion. For that reason I do not know if you'd see the possibility to do a small how-to so we can apply your changes ourself.

Personally I prefer JY roms, and would like to apply your changes without bothering you about it. I understand it's a hassle to keep versions from different manufacturers...
[MTCB Android Head Units Q&A] typos1:
Have you tried just adding the JY launcher ? That is the only difference really.
[MTCB Android Head Units Q&A] i.draskovic:
I'm just wondering, is it possible to use some usb to rca adapter, and if it is possible, how to install drivers? :) I have one usb to hdmi adapter and I would like to try does it works.

and perhaps also the options in android settings that give access to the new features of the MCU... MCU is dependent on each manufacturer....

JY ROM is bit more different than just the luncher

and yes the newest version of JY ROM is up (June 10) and DSA is not interested to do JY Rooting anymore.. so if someone could post the detailed steps to Root the ROM preferably on windows I would gladly Root them and upload them.

easyconnected app is made by carbit specifically for Joyous, that is what carbit techsupport told me in email, and we first noticed it on JY units. Considering the chinese companies have no respect for copyright obvious from the iGo and Sygic sales by them I would not be surprised if they stole the easyconnected map from each other.

My galaxy s4 connects to it with bugs using regular USB,

according to their techsupport lolipop is not supported but it is being worked on.

------------

P.S> according to Joyous the new MCU 2.59 fixes some bugs with the Radio
[MTCB Android Head Units Q&A] typos1:
Not really, only the look of some of the built in apps, which you could also change.

---------- Post added at 11:35 AM ---------- Previous post was at 11:27 AM ----------

I think you have mis-understood DSA, I think he meant he does not want to make hybrid JY 1024x600 firmware, I think he will root the JY 1024x600 firmware if you find it . . . I think, I m sure he will let us know.

Development is done by an Indian developer for ALL the manufacturers, this is why everything looks so similar and ROMs from all manufacturers are compatible with the different units. I very much doubt Joyous do much development themselves. Carbit do not make the app "specifically for Joyous", Joyous units have the exact same SoM as the other units, so its more that Carbit make the app specifically for RK3188/ headunits, do not be fooled by marketing speak ! - the latest Klyde ROMs also come with the Easy connected app. Maybe I am wrong and there is something in the Joyous ROM that makes the app work, but I very much doubt it, as I said earlier, phones need USB OTG to work with this app.
[MTCB Android Head Units Q&A] doctorman:
I am working with carbit to resolve the easyconnected app and they only provide support if they see that I have Joyous ROM
[MTCB Android Head Units Q&A] typos1:
It will work with ANY RK3188 ROM ! The app is in the latest Klyde ROM, I have spoken to Klyde about it !
[MTCB Android Head Units Q&A] doctorman:
easyconnected app is provided on RK3066 now as well so it is not just from quad core anymore

and I was told by carbit that they are making the app for JY , it was a not a sale picth.

I will try a KLD and KGL Rom eventually but I hate losing all my settings and any ROM switch takes me 40 min-1hour seating in the car running idle which is not the best treatment of the engine in the hot weather specially
[MTCB Android Head Units Q&A] typos1:
Really, not long ago it was supposedly only for RK3188 SoMs, nevertheless it works on my Klyde, but not with my phone because it does not have USB OTG.

I disagree about the marketing speak.

Try Titanium backup.

I am interested in rooting this device without flashing a firmware from another device. Just too risky.

Also I want to know what cheap USB 3G Huawei devices are working with that unit.

Known compatibility for now:

For now I can tell you that Xoro mini DVB-T stick for Android smartphones in combination with PadTV App from Play Store and an USB A male to Micro USB female adapter is working perfectly.

But you need a good amplifier antenna.

Also 64GB SDXC is working well when formatted in FAT32.

That App HeadUnit is working well with my device, custom radio apps are starting, receiving signal but then they crash.

So there is no 100% equality to all the devices I think.

Would be great if someone can share experiences with that device.

Car Video Recorder

What app are you guys using for video recording?

I have not played with stock Car Recorder.

I am currently using Daily Voyager started automatically from a Tasker intent. Tasker service starting early from install-recovery.sh.

I like the fact that Daily Voyager produces a subtitle for the video with all the details (gps pos, speed, date and time) however when turning off the ignition and the HU shutdown Daily Voyager is unable to properly close the file. Therefore a .tmp file is created instead of .mp4 without the accompanying .srt subtitle.

I also think this combination is a bit bloated for my HU RK3066 and slows it dramatically.

Wondering if anyone can give me a hand?

I've taken my unit apart to try and fix the hissing mic, but i've got a bit of a different board to what I have seen in pictures.

from KLD 2.49 to 2.55 sound is really different but unfortunatly if i want the shutdown delay of the nice latest [MENTION=3590033]Malaysk[/MENTION] rom i have to keep the last

..and for this reason i have ask to [MENTION=6738895]kumarai[/MENTION] if was possible to have a modified kld2.55 with the sound values of 2.49...i hope will reply..

Hello. FYI, Xtrons is NOT your manufacturer, they are a seller, your manufacturer is Hot Audio/GS.

There is very little risk involved in flashing firmware, 100s of users have done it 100s of times, no on has had a problem flashing the (correct) firmware. Read the first page for a list of 3G dongles.

This thread is FULL of people sharing their experiences with this device, we all have them !! The devices in this thread are all slightly different versions of the same device !!

What custom radio apps are you talking about ?

You rooted 4.4.4 with an app ? This has not worked previously on 4.4.2 or 4.4.4, well done if it actually DOES work now, maybe an update to the app made it work ? But on reflection, the rooted ROMs done by people on here are a much better solution as they contain lots of other useful changes, like repartitioning the space for apps etc. You need Busybox for Viper to work.

Have you tried [MENTION=6738895]kumarai[/MENTION]'s modded MCUs ?

If i understand what you need, all you have to do is connect your camera to a constant 12v source instead of "only on reverse signal" 12v source. On my unit, I have 2 video in rca jacks. One for reverse and the other works with AVIN app. If I want to watch the camera while im driving, I just open AVIN and it shows the video.

If your camera hooks up via rca jack then you would use a rca splitter to send the video signal to both your video in jacks so that it will show video when in reverse and also on demand when you open AVIN app. Unfortunately using an rca type camera , there doesnt seem to be any app available that will record from that signal. Would be nice if someone could possibly modify the car recorder app so that a person could select the source video from USB camera or RCA jack camera. Anyone?? Please??

Hope thats the info you were looking for :)

what is the difference between the 1-5 versions and is it ok to try any of them on my hu?

Also do any of the kgl mcu images have the delay shutdown timer built into them? I find it really annoying that I have to wait a minute for my deck to fire up again after short stops here and there. I know its only a minute but the 30 minute standby would be nice to have for sure! and probably cause alot less stress on the hu over time. Thanks in advance.

It is different version of MCU. I have received my HU with KGL4-v2.20 MCU, but when I have tried to flash with new version, KGL3 works for me. Don't ask me why, because I do not know that.

So, first of all you have to check what version you have in device info. Than you can download right one and flash device. In case that after update your device always boot in recovery mode, don't panic. Just download all versions (1-5) and try all of them. When device boots normally, you have found right MCU. I use version KGL3-v.2.53, and I do not have standby options.
