Hmm. Question : what version number is shown in regards to the MCU in the "about" menu ? Is it possible you're running a 8000+ or higher MCU ? If so, it does not support DVD as long as such an MCU is active I think (grasping at straws here).
[Android Head-Units] cool_head:
I'm using now 4.3.4-1-10-6101 and tested 4.3.8-1-10-210101 and older ones where DVD drive were working..
[Android Head-Units] Skratchuk:
Is your dvd player working now mate?
[Android Head-Units] kaween:
I fear for it. I've done some digging on other Tonghai-related forums, and so far I've only come across people suffering the same problem, but no solutions other than sending the unit back to the seller.
[Android Head-Units] makkan00:
Seems a decent unit.
[Android Head-Units] cool_head:
Nop.. it's dead.. I'm getting a bit tired of this unit.. first the mainboard broked.. i bought a new board that came broken.. I've bought a new board again with another seller and it's ok. Now the dvd broke.. yeah.. Very tired...
[Android Head-Units] ZexGX:
Boot animation logo install failed and now it won't load past the LOGO screen on boot (it gets stuck on a black screen instead of loading the boot animation). Need to update software (wipe it) but cannot seem to get it to boot past the logo PNG (the screen goes black as it tries to load the boot animation and gets stuck). The Wiki says to start the update by holding MENU and POWER keys to boot unit, but that does not work on my Infidini 1-knob unit. Need some help to get it to at least boot into software update mode... Tried holding a variety of buttons while powering the unit on but none seem to make it go into software update mode.
[Android Head-Units] mtresk:
Try to hold POWER and press RESET and then release POWER knob.
[Android Head-Units] cool_head:
Wow.. seems like you have a big problem here.. i think the bootlogo is stored in the mcu.. lets pray that is not a mcu problem.. if it is , maybe you've bricked your unit..
[Android Head-Units] Skratchuk:
Now i have a prorperly working mcu I think I might leave my unit alone now until a major system update!

Hope you guys sort out your units [emoji120]
[Android Head-Units] Miwer:
actually I believe the bootlogo is stored in one of the eMMC partitions. Here's a snippet from the dmesg after boot-up:

<6>[EMMC] partition[1]: start=0x00007C00, count=0x00000400, name='misc'
<6>[EMMC] partition[2]: start=0x00008000, count=0x00003000, name='bootlogo'
<6>[EMMC] partition[3]: start=0x0000B000, count=0x00005000, name='recovery'
<6>[EMMC] partition[4]: start=0x00010000, count=0x00004000, name='boot'
<6>[EMMC] partition[5]: start=0x00014000, count=0x00073000, name='system'
<6>[EMMC] partition[6]: start=0x00087000, count=0x001A6000, name='data'
<6>[EMMC] partition[7]: start=0x0022D000, count=0x00096000, name='cache'
<6>[EMMC] partition[8]: start=0x002C3000, count=0x00004000, name='pqbin'
<6>[EMMC] partition[9]: start=0x002C7000, count=0x00BC8FF8, name='custcon'

I can even open my dd dump of partition2 in an image viewer and it's the bootlogo I selected for my radio. Also the misc and recovery partitions are empty on my unit (all zeros), and probably not used.

Oh by the way, from the looks of it, I think [MENTION=1759114]ZexGX[/MENTION] is having problems with the boot animation... not the boot logo - I must say I don't know where the selected boot animation is stored. I haven't tried to change my boot animation, and now I'm not going to either ;)

/Miwer
[Android Head-Units] cool_head:
ohh god, now I'm stuck in boot logo (the first one) after I downgraded to the initial firmware 2.6.23... When I try to update the firmware that says Update start and then Update end.. I have formatted the microsd card in fat32 and tried in fat but always give me Update start/Update end. The firmware files are in the root of the microsd. Any help?
[Android Head-Units] Miwer:
Try and verify the md5 of the files, after you copy them to your sd card to make sure they are not corrupted (or that your sd card is defective).

One other possibility is that you downgraded to a version that does not support your sd card... maybe too large capacity? have you tried another (perhaps smaller) sd card?

Continuing my previous post...

The boot animation app looks for *.zip files in the following locations:

/system/etc/bootanimation
/extsd
/usb
/sdcard

When selecting a boot animation, the selected file is copied to "/data/local/bootanimation.zip" and made "chmod 755"

Also - the first boot animation in the list should just be named "android" and it actually does not refer to any file (null reference). When this "pseudo-animation" is selected, the bootanimation.zip mentioned before is deleted, and I suspect a default embedded animation is run at startup.

So to sum up:

boot logo is stored raw in /dev/block/mmcblk0p2 partition

boot animation is stored in "/data/local/bootanimation.zip" (if exists)

/Miwer
[Android Head-Units] kaween:
I fear that's the end of it. :(

File repository quote :

"System Version 2.6.23

*WARNING* This update appears to cause unrecoverable bricking of the unit when changing model or MCU. *WARNING* "

Hindsight and all of that, but I'd never flash a firmware with that kind of warning.

At the moment, the only options I see is either ditching the unit and admit defeat, buying another board, or trying to frankenstein a working board with the 2 (or 3 ?) you have already. God, you're REALLY have a stroke of bad luck on this thing. I feel for you.:eek:

Depending on exact problem, it should be possible to use a still-working mcu from one board (you had a not-working gps I think on one of these boards. The MCU of that board still should be good, the GPS sits on the the ARM board.

So careful desoldering of the ARM daughterboard of the "problem GPS" and swichting the ARM with another MAY solve grant a second lease of life to it. If push comes to shove and you see no other solution anymore, and you can't find anyone crazy enough to try and do this, I'm offering to try and do this for you for free.
[Android Head-Units] Skratchuk:
Have you tried the 2.6.60 firmware to try sort it out always worked for me but that might be because I don't have the dvd version hope u sort it mate.
[Android Head-Units] cool_head:
Maybe this is the end of the line for me.. I will put my old RCD 310 headunit again and give up from this chinese crap..

Yup, I've tried every possible firmware.. I even tried via USB pendrive.. Just update start/update end.. My though was if the firmware have to be in a specific folder or in the root of card....
[Android Head-Units] ZexGX:
Well I figured out how to start the update process (had to press the small Reset button while holding the Menu key when powered off). I tried re-flashing 2.7.38 and when that didn't work, tried the full format files, which did the trick! It's back up and running now. Thanks for the reset button suggestion [MENTION=5704177]mtresk[/MENTION] !

Hi all,

I recently bought such a device. actualy mine seems very similar. All the menus are the same and even the passwords match.

But I have several issues with my device. LsqSTAR ST-8213C I cannot post a like because I'm a new member and registered specifically for this. But you can find it on DealExtreme under SKU 329356

1. Button leds blue not working. Red and green are functional

2. How to add lock screen to android. for instance if the radio got stolen I don't want my data all over the street. This feature partly working. I can setup a lock screen be then the system will act strangely. For instance when I use a app to activate the lockscreen the device switches off to standby, But then every time I press the home button to active the device I get a 1frame per Press of the home button displaying the window or app I had on before I locked the device. I can even press all the on screen buttons and then press the home button to see what I did. And sometimes when I go to settings the lock screen as we all know it will appear and I can give my unlock pattern. But the strange thing is if the lock screen is present and I restart the device. It just goes in android without asking for a unlock pattern.

3. Reverse Camera not automatically switched. If i connect the right wires like I did before on other identical units. It should switch when a Video signal is detected.

4. No 2 additional video inputs, fcam and aux-in are the same channel so video will merge when used together.

5. Aux interface makes a buzz noise. When screen brightness is off the sound goes away.

6. There is an option for setting fan speed in the menus. But there is no fan present on my device. Device gets really hot after several minutes of usage. Dont know if this is ok for the device. Gets 67degrees centigrade.

Does any of you know how to solve these problems? I'm mostly brothered by point 1 and 3. I like the leds to be blue and the reverse camera auto switch feature makes it more convenient than pushing the aux app manually.

Hallo daar ! :)

Your device is definitly related to the AN21/Tonghai board, but it is not identical. If the pictures I seen on Dealextreme are 100% correct, it must be at least some different MCU board, as the connectors on the rear are not only situated differently, they're of a different layout and formfactor. As these connectors are directly connected on the MCU board, the MCU itself must be a different version. So be VERY careful when using files from the repository here.

As for you questions/remarks :

1) ... sounds like a bug or a bad connection in the flex that connects the MCU to the front panel.

2) .... you'll need to ask someone smarter than me. Plenty of those people around here.

3) No. The switch to "reverse image" is _not_ detected by the presence of a video signal with the AN21's (in fact, nearly no unit I've ever seen uses the video signal ITSELF to do that), but only by the "high" level input on the "Reverse" wire. Better said, when the wire "Reverse" sees a 12V level, the rear input will display, independant if there's even a video signal present. The easiest way to do so is to wire the "Reverse" wire to the reverse light bulb connector, so the unit receives a 12V on the "Reverse" line when you put your car in reverse.

4) Yep, that's something that several people with other AN21-look-alikes have reported about. I only have 2 video inputs (front and rear), so I don't have that issue.

5) Haven't noticed that so far. Will check. Aux is used for my front cam, no sound connected.

6) Yeah, I know. The ARM gets pretty hot as I reported earlier in my "AN21 Tear down guide". As your backplate does not have any openings, putting a fan in there is pretty much useless unles you make some kind of hole there. The mcu will probably have a small 2 pin header for a fan connection but as said, it's no use building a fan in a unit that has no opening for a fan exhaust.

Doei ! :laugh:
[Android Head-Units] TimelessNL:
Thank you for your information, and indeed "Hallo daar ;)"

But yes I was not planning to do any firmware update to this device at all, I just wanted a all around device with a basic OS that I can install applications on and not kindly forced to use the default factory one's. Strange part is that the firmware version numbers match, even the "Select device" option matches the output of the posted files here at the forums. and yes the DX images are identical.

But just to add some things:

1. The thing is, there is an option to give the On Screen Buttons the same color as the Physical Buttons, So when either you change the LED color the GUI will also automatically change to make it more convenient. But the thing is... these colors do not match, when I select "Color 1" which turns on the RED LED's the GUI color is actually GREEN. and the same is for "Color 2" which will light the LED's GREEN and change the GUI to BLUE. so something in my mind gives me the impression that the Color ID"s are wrong in software or/and hardware. I don't have that "Color app" installed. this should be there because the DealExtreme images showing such an app.

2. Ok I keep that question open

3 and 4. OK this is some progress. since I'm going to work on my car tomorrow I make this question bold, because there is still something strange and I need it to be answered otherwise I cannot continue soldering the extra cables. The thing is: I don't have such a "Reverse" wire... I don't know why but my wiring seems to be strangely named. I have strange wires like [CAM - LINE], [ AMP LINE] and [FCAM -12v]. The [CAM - LINE] could be something like the Reverse wire right? I've tested it while connecting it to GND and it did not do a thing, so maybe connecting it to 12v+ will make it switch to the reverse image?

And also the [AMP LINE] is important because I'm planning on installing a AMP with Sub woofers. Should this then be the AMP enable wire? something which is normal called a AUX Enable wire which is normally blue colored and in this case brown.

another strange thing is the [FCAM + 12v] I expect F-CAM to be Front CAM? which would mean it should provide 12v when either I switch to the AUX channel or the special FCAM Chanel (if it is even there). The opposite is actually the the case it always providing 12v+ . I could thing of a way that the device enables that 12v only when the user want to display the Front Cam, that way you can use 1 input as 2 different ones because only 1 video device is enabled at the time.

6. The problem is if I just cut a hole in the case I will lose my warranty and such. even opening the device is not prohibited

Proud new owner

I just received my unit and installed it this week. It is a little different faceplate than most of the others I have seen, but I assume since it is listing similar numbers for MCU and Firmware that I'm in the right place. I have MCU 4.3.8.1-3-10-040201 and SYS 2.7.39. It is a 5 button with one knob unit, a DVD, and a 6.95" screen, 2 USB's on the back, one mini USB on front, built in wifi and Bluetooth, with most of the same menu options and pre-installed apps I've read about in this thread.

Here is the unit: http://www.aliexpress.com/item/New-...DVD-for-Universal-3-with-Dual/1976338697.html

I have not rooted this unit yet. I don't quite have enough confidence. I've carried a rooted phone since the OG Evo, but the risk to reward ratio is not there for me on this one. :)

I do have a question about Bluetooth. I read a post by a guy earlier in the thread who successfully got a OBDII Bluetooth dongle to pair to his headunit. I have a cheap Chinese Bluetooth dongle from years ago that I can't get to pair. I can pair to it with my phone but it requires a pin (it is either 0000 or 1234, I can't ever remember, but I always HAVE TO TYPE IT to get the pairing to work with my phone. I assume that the reason his unit pairs with his dongle is because he has a dongle that doesn't require a code to pair. As in his previous post describing the process he said there was no code involved.. It just paired after he selected it from the menu and pressed "ok".

Would anyone who has successfully gotten a Bluetooth OBDII to pair please post a link to exactly the OBDII device they are using? If I could get Torque to work, I would be 100% satisfied! Thanks!
[Android Head-Units] storm83:
This is awesome and will fit my Trans Am perfectly! Question though... I really haven't messed with the boot animation before. Is there something special you had to do to get this working? I tried it out yesterday and I either just get a black screen or the android logo while I'm booting. I rooted my unit and put the zip in the boot animation folder and set the permissions to the same exact as the other animations. It shows up to select it and everything... just no logo when I boot. Any help would be awesome!
[Android Head-Units] TimelessNL:
Haha, thats true!

Yeah I would like to give that a try, maybe the colors are just wrong numbered. so I can give it a try and see which color represents blue.

Yes the CAM LINE is a unshielded wire, matter of fact I only have unshielded wires there exept the GPS ofcourse. But thanks for your suggestion. I mesured the wires and indeed when I connected the FCAM +12V as a test to provide 12v to the CAM-LINE the radio switched to reverse imaging. so your suggestion was correct. I wired this wire to the backup light of my car. And it is now functional.

Ah I receive my subwoofer tomorrow and I will test your findings. I hope I don't have that same problem. I want to level the gain of my speakers and subwoofer separately. Because this radio is simply not powerful enough for my 110W RMS speakers. so when I turn the volume up to loud the sound get distorted and the amp starts clipping, with low bass and only enable the Mid and Hi range frequencies the unit goes great with those speakers and the sub will then provide the low frequencies, maybe I can solve the individual gain control by wiring the remote from my subwoofer to the front and to replace the subwoofer gain on the radio. But I'm out of space on my dashboard so I hope I can do it by software in the EQ. only if that pop sound is not noticeable.

Yes you are indeed correct. I was just hoping that I could disable that 12v Output with a software button so the camera can be turned on and off. That powersupply of those car camera's are getting really hot. I now put the camera on the fog lights. so for the meantime I have the abality to only use the camera when I need it. and also providing additional light for the night.

Yes thats true, maybe if my warranty is expired. I can do such modifications.

Another thing, does any one know how the Equalizer is being configured.

[IMG="Equalizer"]https://dl.dropboxusercontent.com/u/13519734/Nissan%20Primera%20Project/Knipsel.JPG[/IMG]

For instance, what does this Bass[F], Middle[F] and Trebble[F] do? I thought maybe the [F] stands for front. but the opposite is true, when I put the normal bass on the highest point, moving the BassF higher will only lower the actual bass sound of my speakers. I thought maybe I reversed the wires of my speakers so the bass gets muted when using both the Front and the Rear speakers but the wiring is correct. Also when the BassF option alone does nothing when the normal Bass is on the lowest position.
[Android Head-Units] kaween:
You should see it like this : with the EQ, you can select the LEVEL of effect in a frequency slot (the LEFT part of the controls), the RIGHT side determines the frequency range in within that band that will be affected by it.

Hence the effect that if you for example put the left "BASS" to zero, changing the Frequency range will do NOTHING as there's no "effect weight".
[Android Head-Units] MileHighClubAV8R:
Thank you Kaween for the help on Bluetooth. I had previously not gone for a USB ODB2 due to the fact that all the ones I saw were longer than I would like. The Bluetooth ones look lower profile. My OBD port is right in front of the drivers left knee and I need a low profile dongle so it's not terribly visible and so I don't bang my shin on it. I found a solution for this. I bought a low profile OBD male to OBD female extension with a ribbon wire. It should be easy to tuck away under the dash then plug the USB OBD device to it!

Now for another question. I am spinning up a 2 TB external HD but any other USB device is now intermittent. I need more power to run USB devices, including the sweet new USB OBD scanner I have coming in the mail! I have read on this thread about powered USB hubs. I looked around today, but most of the car powered USB hubs are intended solely for charging. Now, I considered buying a 12v standard wall wart USB hub and clipping the wire and putting a cigarette lighter plug on, but I read on this thread about a guy who fried his USB card in his head unit doing that and another guy who had shown with a voltmeter some retrograde voltage coming into his unit from the hub. Of course, I want to do this the safest possible way. Does anyone have a good powered USB hub setup in their car that has worked safely for them over a fairly extended amount of time? If so, can you tell me where you got the unit from or how you made it and what materials you used? Thanks!

[Android Head-Units] makkan00:
Guys

I have this unit but having following issues;

1- When I go into navigation and set the route, each time I touch the screen it changes the track / radio station. Is there a way of turning that off?

2- Radio (FM) reception is very bad when car moves. When I put the oem radio back, everything is fine. Its when I put this radio it, reception is poor.

looking forward to hear from some gurus.
