For the default language, you need to open the .img with Dragonface v2.2.5, go to "Advance Settings" Tab and click on the "BuildProp File" button, head down to this section:

persist.sys.timezone=Asia/Shanghai

persist.sys.country=CN

persist.sys.language=zh

and change it for something like:

persist.sys.timezone=America/New_York

persist.sys.country=US

persist.sys.language=en

save it and burn that modified image

...for the screen mirroring, Im not sure yet
[Android Head-Units] CompletelyNumb:
You rock! Some googling shows me there are apps that can calibrate the screen, but the playstore doesn't want to load, just sits there thinking. I did get wifi working however. Going to try to get ADB going as well, see if I can't push a calibrating apk over.
[Android Head-Units] rubenjavier:
For the Touch screen miss calibration, you need to open the .img with Dragonface v2.2.5, go to "Advance Settings" Tab and click on the "System configuration" button, head down to this section:

[ctp_para]

If your touchscreen senses on the left part whenever you touch its right, look for:

ctp_revert_x_flag = 0

and change it for:

ctp_revert_x_flag = 1

If your touchscreen senses on the bottom part whenever you touch its upper, look for:

ctp_revert_y_flag = 0

and change it for:

ctp_revert_y_flag = 1

If your touch screen is reverted / reversed like if you slide up it works left to right,

look for:

ctp_exchange_x_y_flag = 0

and change it for:

ctp_exchange_x_y_flag = 1

(it will turn its x-axis to y-axis)

save it and burn that image

This site explains this phenomenon (its because the firmware didnt synced with the hardware)

I hope this gets you a fully working Head Unit again

Enjoy!!!

Sadly I've been unable to successfully flash the HU with any of these edits. It seems as though any image file that's been edited by DragonFace fails, either in the installation itself, or the HU will hang up on the boot logo afterwards with the same error of "CODE 1".
[Android Head-Units] rubenjavier:
Another Batch of questions answered by Thomas from InDashNet

Q.-What is the pre-amp voltage of the RCAs?

A.-​~2.5V​.

Q.-Will reverse camera work from immediate start up (before Android fully boots up)?

​A.-Immediate​

Q.-Any information on the FM radio chip?

​A.-There several options from ST to NXP.

(need to get back to this question, to get a list of the options available at this time)

​

Q.-Any information on 3G (or 4G) dongle compatibility?

A.-20+ 3G​ dongles are working(UMTS/HSPA, EVDO).

(need to get back to this question, to get a list of the options available at this time, and about 4G dongles)

Q.-What canbus features will work with the dedicated Audi car model units? caller ID in DIS

​A.-Canbus need longer time to confirm.​

(I also asked about my Peugeot 307 CAN BUS integration, giving him the model/year of the car, and a couple of CANBUS decoders that works with other HU from the people at connects2, and he said he'll look in to it and get back to me next week)

I' will update the Info Post
[Android Head-Units] rubenjavier:
Updated Android 4.4.4 and Testing Lollipop 5.1.1 imges

I wrote Thomas about your situation and the issues with his default 4.4.4 image (language and reversed horizontal touch), aand the software versions we re using of Dragonface and PhoenixCard

He wrote me back, regarding your issues:

"I uploaded a new version(and a trial of 5.1.1 as well). Language is controlled more than the ​Dragonface setting change. CTP is also not as common Allwinnner setting, we build a new structure and can set in factory parameters."

So, check your emails to see if anyone has got the links yet,

If somebody has the links, pelase post them here, to add the upated Android 4.4.4 imge and the testing Lollipop 5.1.1 image (F*** Yeah!)

I'll write Thomas back, to see if there are tools that allows its images to be edited and repacked(Dragonface can unpack, but the repack is wrong), and some instructions (windows or linux)
[Android Head-Units] CompletelyNumb:
Thomas did in fact email me the 5.1.1 image to try, will report back shortly. https://drive.google.com/drive/u/0/folders/0B8Nj9XViGv_6MHh5cEdydkE3NjQ
[Android Head-Units] touchpt12:
Lollipop Install

Just installed Lollipop on my head-unit. Initially you get a CODE1 error when installing the image but it progresses through the install giving a CARD OK notification. The Google Playstore is not installed so it will need to be installed manually by browsing for the APK online (Playstore version 6.3.16.B-all [0] 2697688). I found one on APK Mirror website.

Will report anything else that I come across.
[Android Head-Units] rubenjavier:
That's great!

I saw that Playstore was mising, since I unpacked the image with Dragonface and took a look around (the image unpacks in the fsop subdir inside Dragonface folder), also saw the build.prop, default apks, the current CANBUS list of vehicles, and the possible Car Brands logos, the wallpaper looks colorful.

I've been reading a little and the fastest way to customize the ROM would be to burn the image on the SDcard with Phoenixcard, and read the card in linux, since the card will be in EXT4 format, then change the bootanimation.zip, the bootlogo, set the default language/timezone, location, or add/remove apks, also remove some bloat like the old Galxy4 or Holospiral android wallpapers

in theory you could do that from windows using something like Ext2Fsd, ext2expolerer or DiskInternals Linux Reader to read and write on the SDCard with the image... but I cant asure it will work..., Linux will

For something more advanced like change the ctp_params or add new drivers, you will need to look for the script.bin file in one of the partitions of the SDCard created by Phoenixcard, and use SUNIX tools to conver the script.bin file to a text file, edit it and turn it back to a binay file (FEX format) on the same palce you found it.

here is the SUNIX FEX guide with the possible options:

http://linux-sunxi.org/Fex_Guide

here the SUNIX tools for windows:

https://github.com/OLIMEX/OLINUXINO/tree/master/SOFTWARE/fex-bin-convertor-windows

and here the SUNIX tool for linux:

https://github.com/linux-sunxi/sunxi-tools

Hope you enjoy your units and report some lollipop goodness ;)
[Android Head-Units] CompletelyNumb:
Same here. It seems quite a bit smoother than the previous version. No X axis issues. Appreciate the proper play store version, that's what I'm currently working on. Although after installing it doesn't seem to want to open, just get the usual play store has stopped working error. Do I need to download play services separately?

I do notice some slight audio feedback from my speakers when moving between certain apps and menus.

Steering wheel mapping isn't working on this version either. App crashes the HU when you try to set a key.
[Android Head-Units] rubenjavier:
Added the two most recent versions of the Playstore apk to the resources list on second post of the Thread
[Android Head-Units] swyner:
Hey you have VW right? Is your steering wheel controls working and anything showing up in the MDF (like radio station or RDS)?
[Android Head-Units] j0bro:
Sigh, I attached SWC in all possible permutations but to no avail. Even got my portable oscilloscope out to check the signal. Everytime I click a button, a different voltage between 0V and 5V is seen on the line. But connecting it to either Key 1 or Key 2 doesn't give me anything in the SWC setup UI. I also set the Canbus setting to KIA_HY in the system settings.

Any suggestions?
[Android Head-Units] kwalsh24:
Yep in have a Vw but it doesn't have swc . as for the mfd nope not a thing there

Anyone using any of the preouts? Not sure if my sub amp has failed or if none of the preouts are working on my unit
[Android Head-Units] swyner:
Ya that sucks. I don't think any of the canbus modules are performing correctly. Arg.

I am using preouts. I have front and rear left and right going to a processor then out to amps. These preouts seem to be full signal as I am getting similar sound as with OEM (albeit with a low level whine) for what its worth I tried ground loop isolators on rca and thought I broke my sub amp. It was the ground loop isolator that was taking all mid bass and bass signal out.
[Android Head-Units] samdu:
I'm using the preamp outs. Works remarkably well. I was expecting way more of a hassle in that department.

Check resistance, not voltage.
[Android Head-Units] twokidsandaphone:
Did you connect ground?
[Android Head-Units] j0bro:
I did connect the car's SWC GND to the black GND wire that is part of the wire harness where the Key 1 and 2 wires also are. Should it be differently?
[Android Head-Units] twokidsandaphone:
Nope. Just checking.

WIFI 3G

Hello

I have this Problems: I cannot turn wifi on since lollipop update and 3G is connecting sometimes and sometimes not without any logic (There is a (!) shown in connection strenght not "3G"). Time changes After every restart.

Are there any solutions for this problems?
[Android Head-Units] kwalsh24:
Hmm yeah I think my amp may have taken a dump as I looked at it after messing around with the radio and seen that it was on a constant protect mode. Good thing I have a spare lol. Add that to the to do list
[Android Head-Units] rubenjavier:
no, it should be as you have it, key1/key2/GND(thin wire from the keys budle NOT the 12vGND), I assume you are checking the volts againts that thin GND wire

Try with the 408 on the CAN BUS configuration, at least I can vow that it works when you set it and then go to the SWC configuration screen (I dont know exactly what does that do, since I had to confure the keys anyways, but before that the keys werent readed)

restart the unit after selecting 408 with the restart option on that same Factory settings page

after restart go to the SWC screen and

.-hit RESET

.-press one key on the screen (vol+) (and press for more than one second, sometimes it dont read the touch lightly)

.-now press the vol+ on your wheel, the vol+ key on the screen will turn lightblue

(if this worked, then keep doing it until you have all the keys you want configured)

.-when you have a bunch of key on the screen in ligthblue, hit SAVE

.-after that, turn off the vehicle and wait until you know the unit is off and will cold boot

if all this fails, write to thomas and tell him the voltages you have right now for your key strokes (vol+-, next/previous, src button)

I need to meassure mines and send those to him so there can be a preconfiguration for my model

(also he told me that in a future update, other physical buttons of the unit would be configurable on that screen)

best of luck friend
[Android Head-Units] rubenjavier:
This is an Awesome Player, Thanks

NOTE: on the store it can't be installed, says that is incompatible with the device (bull$hit), I bought it on my phone and installed with an apk I downloaded somewhere else, then installed the unlock key from the store (yes the key does work from the store) and everything is working perfectly, it reads all the FLAC tags correctly and the embedded album art, also have a huuuge set of customization parameters
[Android Head-Units] rubenjavier:
Did anyone was able to use the "Easy Connected" App?

I can make the unit detect my phone with the cable on USB debug,

but then I get a screen saying:

"Software Activation"

Hardware ID: some_large_number

MOB IMEI: some_large_number

Channel: ZXWL Network Connection: Normal

Remaining authorization number: 0

And then this dialog:

"Activation failed"

Reason: MOB not licensed of activation

replace a MOB used for activation to retry or contact the supplier

HID: some_large_number VID: some_small_number

IMEI: come_large_number

If anyone has any idea what can I do, I'll be very thankful
[Android Head-Units] swyner:
I have not tried on the In Dash unit....I used a similar app on another Android Head Unit way back in the day. I had this exact same issue with that one. It was something to do with the licenses and Thomas would need to investigate
[Android Head-Units] twokidsandaphone:
Is anyone willing to answer this? Trying to decide if I should give up my Newsmy for this unit.

Thanks!

Jeff
[Android Head-Units] kwalsh24:
I had a newsmy and this unit blows it out of the water. Even in it beta stage. Ill try to find an answer for your questions in the next day or two as I do have a 1tb external drive I can attempt to use on it. Not 100% certain if my powered usb hub works anymore that I had setup with my newsmy or not.

The unit so far actually works well with its 60 min delay power off.
[Android Head-Units] kwalsh24:
Found a glitch with the unit and my Vw. The canbus isn't 100% correct with my car. Normally the radio will stay on until the key is pulled & a door is opened. This radio turns off after 20 or so min. Which sucks as I do enjoy a drive in movie every now and then so I require the radio staying on for a period of time... Blah. May have to replace the canbus box on the unit. Boo. Nice part is my unit came with a complete secondary harness that doesn't have a canbus attached.
[Android Head-Units] t.idn:
No problem. 2T usb hard disk was tested.
[Android Head-Units] swyner:
Mine too (Audi). This is something I have been talking with Thomas about and is on my "issues" list. Exact same issues as you...no SWC, the unit goes off immediately upon turning ignition off....it should stay on until key is removed (ie no ACC on VW/Audi cars), no information from Stereo to DIS or MFD. Also, pretty much all other Android units I have used and researched have 2 way Canbus so the unit can read information from the Canbus and display (ie tire pressure, door open, A/C info). I am hoping Thomas will get on the Car Specific Canbus module update ASAP. I know there are quite a few of us waiting.

I have thought about finding or using another canbus module that has worked in the past....problem is 2 fold...the wire harness to the Canbus module is different (ie power, ground, Can Hi, Can Lo, etc) and there is specific software that needs to be able to work and "talk" with the module. Our cars cannot do any SWC or pretty much anything else without Canbus DATA (not voltage pulses).
[Android Head-Units] kwalsh24:
My question is... Can he update the module or is that a 3rd party? Ill give newsmy credit they had a half decent canbus unit built into their radio. This one isn't as bad at the huifei radio I started out with (yes this is my 3rd radio lol)

If he doesn't get it working ill just replace the original wiring harness with the axxess canbus box I ordered off eBay
[Android Head-Units] j0bro:
Why should we depend on all kinds of external adapter hardware? I am pretty sure the whole CAN bus decoding thing can be done in software.

---------- Post added at 03:53 PM ---------- Previous post was at 03:44 PM ----------

@t.idn Will the unit support acting as a bluetooth client (is there hardware support built in)?

I would like to tether over Bluetooth. Accessing the Bluetooth setting makes the Settings activity crash.
[Android Head-Units] swyner:
Not sure...every single stereo I have used as well as every harness has an external Canbus decoder box....it's likely slightly more complicated that software as I see inside the box is a control board which needs to process incoming Data from Canbus, convert to outgoing signals the head unit can understand. For VW/Audi, this includes remote turn on, reverse, speed, Can Hi and Lo.
[Android Head-Units] swyner:
All. I have uploaded a log file into this google drive folder as discussed before. I am just figuring my way around how to ensure you can update it and save it but if anyone can help, would be appreciated. Also, feel free to change the file to a better format but at least something is started.

Anyone else running aftermarket amps (using the RCA out from InDash) and have really low alternator whine? I get when music is muted or changing tracks but it's not that noticeable. I didn't get this on other units including Android and name brand....has to be something in the DAC Audio controller....just curious if it's me only
[Android Head-Units] samdu:
Not sure if it matters that it's not aftermarket, but I'm running the InDash through the factory Bose amp via RCA plugs in the Miata and don't have any noise at all.
[Android Head-Units] kwalsh24:
I have background noise. Its like a weird clicking sound. When my amp was working (and perhaps this was the amp) I was having a rolling thud sound coming from my sub, again that may have been the amp telling me its heartbeat was soon to end lol.

I've had weird issues with every android unit I've owned. The newsmy gave me horrible feedback on my aux in line which made me install a ground loop isolator. Perhaps this may be required on my sub like now too... And perhaps be the same results for you swyner
[Android Head-Units] swyner:
Ya, I have Front and Rear out from the InDash to 2 sets of RCAs going to a processor before my amps. These Front and Rear (L&R) are full signal and don't use the sub out RCA from InDash. I tried ground loop isolator (PAC SNI-1) and it cut all the mid bass and bass out of the signal RCAs.....I was trying to read online as to what is going on but can't find a concrete solution....some say the SNI is hooked up backwards (ie out is in and in is out) but I know how to hook these up LOL. Some say that is what happens with GLIs....can have an affect on the signal output, etc. Just frustrating as you are right kwalsh....this is typical for ANY Android unit I have installed (except one) and never and issue for me with name brand or OEM.....It's barely noticeable but enough to drive me crazy when driving with no sound (ie wife in car) and I can hear the faint whine and interference....
[Android Head-Units] kwalsh24:
The only other thing you could try is running a direct ground for the HU itself and see if that helps any...
[Android Head-Units] swyner:
so instead of going into my Audi harness, splice that and ground to chassis ?
[Android Head-Units] kwalsh24:
Yep. Give it a try and see what happens. As that ground used by factory is a ground that nearly everything in the car uses. It could be getting feedback thru that
[Android Head-Units] kwalsh24:
Has anyone had any luck getting Google play to download anything on the latest Rom? Mine keeps saying downloading and won't actually download
[Android Head-Units] swyner:
I am on 073 and working fine. No issues with log in and downloading.
[Android Head-Units] kwalsh24:
I had no issues on 72. 73 nothing wants to download in the play store. Everything else that uses the net downloads fine. Even tried a refresh and same results. Grr!
[Android Head-Units] swyner:
Tried this with no change. Its the RCA out from the DAC not playing nice with aftermarket amps. I am confident the low voltage and quality of the DAC is causing this.
[Android Head-Units] kwalsh24:
Hmm boo. That's not good to hear. I sent Thomas I audio clip of what my radio sounds like with zero sound being played. I had horrible buzzing feedback but it stopped before I could grab my phone. I believe my buzzing sound (which comes from the head unit itself and not thru the speakers) is from the screen itself. It is worse when the screen flickers like I've reported its a constant buzzing sounds like a tft bulb bout to fail.
[Android Head-Units] samdu:
Yeah, that sounds like an actual hardware issue.
[Android Head-Units] kwalsh24:
Yeah I sent the sound clip to Thomas and he reported back asking if the sound is constant or if it's when the screen flickers. Its becoming more constant even without the flicker so be interesting to see what he says

I'm also finding the screen rather weak colourwise. Almaot like the contrast is cranked way up
[Android Head-Units] swyner:
That sucks dude. Definitely a display/backlight issue that I have no doubt Thomas will replace.

The colour on my screen is "average". Not worse than anything else I have used but not super bright and "popping" colours. If you look real close at the screen, there seems to be an antireflective coating on 99% of the area exposed. I can see a very slight change right at the edges where it's definitely more reflective where the coating stops. I think this is not helping the "clarity" and "pop" but DEFINITELY helps the glare...I would say of all the Android Units I have used, this is by far the best at seeing in direct sunlight.
[Android Head-Units] kwalsh24:
how is your screen for viewing along the edges? Mine actually cuts off slightly if there's text right out to the edge of the screen... Can be annoying to see when sitting in the drivers seat
[Android Head-Units] swyner:
Mine sits lower in the front dash (Audi TT) and yes, approx 2mm up from bottom of my screen is where the display stops.....seems right and left are ok (display is right to the edge). Will look closer but it hasn't bothered me at all....like if it was significant deadspace (like 5mm or more) it would look "cheap".....
[Android Head-Units] kwalsh24:
Kinda wish mine had a 5mm spare left n right up and down is okay
[Android Head-Units] j0bro:
Yeah the bezel is quite high, so it protrudes along the edges enough to just block a slice of what is going on in the margin. It makes pressing the software Back or Menu buttons a little awkward sometimes but overall the viewable area is quite alright.
[Android Head-Units] swyner:
Well in all my testing of the Audi specific harness (as with kwalsh, amp and ANT turn on was crap voltage and not correct) I found a good connection for both ANT and AMP (red wire which is remote turn on from canbus module). I have totally hacked my harness up but put it all back together and now I am not able to turn off the InDash unit.....I think the canbus adapter is pooched or something. Also, I used to have canbus service start up (along with GPS service) in the foreground but this canbus service has disappeared. Anyone with a car specific canbus module have this issue? I am going to re flash 073 and see if that fixes it. If not, then it's hardware (or wiring) from canbus box......arg.
[Android Head-Units] kwalsh24:
There's a canbus service? I don't think I've ever seen that. Just gps & bluetooth

I found a 12v source on a open set of pins that my guess are used for a plug set that either isn't included with the radio or I'm just not using. I attached a photo a while back. I'm using it for remote turn on. May source another for the antenna as I bet its not strong enough for that either as my reception isn't the best. Which is likely the radio at fault but worth trying another spot when I tear the dash out to replace the can bus box.

View attachment 3778577

Imo I think we might be better off replacing the can bus box with something else. As every unit I've owned over the past 4 years reacted nearly the same as this can bus box does. I think its the maker of the boxes that controls the programming. Not the maker of the head unit.
[Android Head-Units] rubenjavier:
Hey [MENTION=2251099]swyner[/MENTION], I just checked the logfile, good work,

just one thing, I share mos of your same issues (as I suppose many of us do), but you have marked them for your specific Head Unit model, do you mind if instead of every one of us, repeating the same lines over and over again, we just add our usernames on the user column of those issues, and our HeadUnit model to the model column?

Also I think we could use a votes column, so each time one of us has the same issue we upvote the issue adding +1, this way is easier for Thomas to identify the most common and the most needed to be fixed first

I know its not the best way, but until we get the HeadUnit source on git with correct issues handling, at least is something.
[Android Head-Units] kwalsh24:
Hmm user names or our real names so Thomas knows its a legit comment coming from a legit owner?
