Go big or go home. I'm flashing it...if it'll download in less than 3 hours...

---------- Post added at 10:48 PM ---------- Previous post was at 10:40 PM ----------

Just flashed the original 2.7.11 (Android 4.1.1) and it did the same thing, folders are empty. I'm trying a factory reset with the 2.7.11 firmware still flashed; last time even when I went back to 2.7.9 I still had to do a factory reset to get my access back. It does have the newer stock apps though.

---------- Post added at 11:03 PM ---------- Previous post was at 10:48 PM ----------

Good news, kinda. I have root again with 2.7.11, but a lot of directories are emtpy. \system\etc\mcu\ is empty, \data\ is empty, etc.
[Android Head-Units] jpapadami:
There are 2 new firmwares floating around, one in which PsycoMcSatan said in post #3630 that it might be Android 4.2. Which one did you try?
[Android Head-Units] booba5185:
The original 2.7.11 (Android 4.1.1), and I'll flash the 4.2 once it's done downloading...in 2 hours, lol.
[Android Head-Units] jpapadami:
Lol. Pretty long for 145MB. Let's just hope that it is rootable. BTW, so I get it that the current method for rooting works with 2.7.11? Too bad that "mcu" and "data" directories is empty. Have you tried to enable hidden files? Maybe their hidden by default?
[Android Head-Units] booba5185:
Rooting did go as normal, however the default USB Device messages are back.

I did try enabling hidden files, with no change. I have relatively fast internet, this is just downloading slow. It has roughly 45 minutes left now, but I'm gonna call it a night and try it tomorrow when I get home from the junkyard...with an aluminum subframe and an aluminum oil pan.

Someone mentioned about updating MCU after rooting, i have tried looking for that MCU update but cannot seem to find it has anyone got the link to it please.

Sorry if this is asked a million times already but where can i find the MCU to 4.2.15-1-10-2101 update that i was advised to update to after rooting?
[Android Head-Units] KID52:
From what I have been told, the 4.2.2 version is extremely buggy and not ready for mainstream release yet. I was offered a copy of the system files but was advised against using them until the bugs had been worked out, although I wasn't told specifically what the bugs were.

I would proceed with caution on using the 4.2.2 update, and only flash if you do not rely on your unit.
[Android Head-Units] j2gifted:
I like my unit as is on 4.1 ...whats the benefit of having 4.2 except being able to say h have 4.2?
[Android Head-Units] jpapadami:
FYI, you need to go to "system > etc > mcu" and that's where you'll find the mcu files. Unzip the one you need to your sdcard and update it. Anyway, here they are

https://www.dropbox.com/s/j5dftqpwz2k27xb/mcu2.7.9.rar

4.2.15 mcus are towards the end of the list.
[Android Head-Units] KID52:
Not sure of the exact changes, but it should have MirrorLink.
[Android Head-Units] Skratchuk:
Nice one for that.
[Android Head-Units] tdt038:
You can connect two monitors. Splitter is not needed, because the unit has two rca video outputs. Dual zone (unit > monitor) works with DVD and AUX VIDEO IN only. Mirror image from the unit can also be displayed on an external monitors, provided that in the background running any stock apps (radio, music or video players).
[Android Head-Units] Skratchuk:
Has anyone managed to bypass incompatible app problem when trying to download apps from play store if so how do you do it?
[Android Head-Units] Suzook1:
sorry I am a little confused

hi there and thank you for the reply. I am a little confused. You say the dual zone only works with dvd and aux video in? Dont you mean out?

I just want to be sure that lets say I am looking at google chrome on the unit, that both of the external monitors will see that as well.

Also, is the 7 inch versions out there pretty much the same features and able to be rooted?
[Android Head-Units] MFKinSINY:
Maybe your file explorer (ES File Explorer and Root Explorer are my preffered) doesn't have the setting checked to "show hidden files"

Check ALL of your setting in your file explorer. Good Luck!!!!
[Android Head-Units] jpapadami:
Just download it somewhere where it works (e.g. your phone) and then use APK Extractor to extract it and put it on your unit.
[Android Head-Units] bwthor20:

Guys, does anyone have any idea, why the heck is the Tomtom not working particularly on this unit ? I've tried to solve the problem with Tomtom support but with no success. They were just repeating that the application is using google location services to obtain gps signal. They finally returned me the money. Any ideas ?

Thank you all for the replies. One final question, do any of these offer Digital tv tuner options so I can pick up HD channel over the air?
[Android Head-Units] tdt038:
Before buying you can discuss this option with the seller.
[Android Head-Units] Cavalier Condorelli:
I had the same problem with ES after I installed it from the market. I solved reinstalling the older version that the Unit comes with. I found it in the apks directory of the sdcard.

Cores showing stopped/offline?

Here are some picx of my stats and apps, I noticed no apps can change the Governor either, probably just the Kernel...

Anyone know why does it show cpu offline?
[Android Head-Units] Zaphod-Beeblebrox:
Can you expand on this a little bit. What System/MCU are you on? Are you using built-in Bluetooth or an external dongle (I don't think dongles work with this unit, right?)

Did you have to do anything besides just pair within the Bluetooth app?

I've got my unit pretty darn close to dialed in the way I like it, but I prefer to Bluetooth tether as opposed to WiFi (reduced battery usage on my phone, plus I rely heavily on Bluetooth headset to my phone, the WiFi tethering creates a lot of interference/static)

I don't do any high-bandwidth streaming, but I LOVE Waze as my Navi. Just needs a constant connection, even if it's a little flaky.
[Android Head-Units] balaes:
Has anyone tried the update 4.2.2 ?
[Android Head-Units] KID52:
System is the latest update, 2.7.11, MCU is 4.2.6-8-10-E501, the unit is the 7 inch one without a DVD and a volume control knob on the left.

I am using the built-in Bluetooth, and have not tried a dongle however I don't think they work as you say, they didn't work with my old unit.

Didn't have to do anything other than pair with my phone and connect, then internet was shared. As I say though, the connection seems really temperamental and even struggled with Waze, got stuck in traffic and tried to submit a warning but it never sent. Best I have managed to use it for is loading the Google homepage and that is about it.

I will test it out again though, however I think my phone may be partly to blame as even the WiFi on it is also useless (cannot see home router about 6m away through 2 walls, any other device gets full signal).
[Android Head-Units] KID52:
On another note, since the security menu is locked, does anyone know a good app for securing the unit when the car goes in for services etc? Would prefer if people weren't able to mess with it.

Also, are there any good GPS automatic logging programs? Both for logging personal journeys and for seeing where it goes when I don't have the keys...
[Android Head-Units] babijoee:
Flashed on top of 2.9.11 no issues so far.
[Android Head-Units] jpapadami:
Can you root it using the traditional method? . Is it buggy? Any changes (new features, new stock apps, new mcu etc...)?
[Android Head-Units] babijoee:
I haven't had a chance to try root yet. So far I don't see any noticeable differences and doesn't seem to have any new features.
[Android Head-Units] chan.jmc:
Be careful with this ...

I messed around with this setting, didn't seem to do much, but then when my unit crashed (reason unknown as of yet), when i rebooted, the internal storate and microSD were switched and as a result Waze could not access the internal storage and Es explorer showed that the internal storage was not mounted for some reason. Easy fix though, I just turned the "Switch SD Card" to "Close" and Waze was able to access internal storage again and function normally.

Side note, I've been tethering internet from my Nexus 5 without a hitch until today. After the crash, internet speeds were super choppy and unreliable until i rebooted the phone. Do you think this has something to do with the unit or my phone? So many variables, will have to keep using and testing to eliminate causes I guess, but if anybody else has experienced this, what was the cause of your issues and how did you fix it?
[Android Head-Units] Skratchuk:
NO SOUND

NO SOUND! the app is playing but unless i use either use the standard radio or music app I get no sound Anyone else know how to get audio to play again or have this problem?
[Android Head-Units] chan.jmc:
You might need to set your sound priority to 3rd party. Go to settings > sound > sound priority

If that doesn't fix the problem, then an alternative fix may be to open any stock application (eg. radio, music, dvd) then press the back button. When you go back to Tunein Your audio should be restored (and any other apps you've installed)
[Android Head-Units] Skratchuk:
Thanks for the info mate tried all that but unfortunately didn't work atm I have no sound apart from radio and mp3 and also if I play any audio my eq settings don't come on till I click on eq and adjust something. Does this sound like a bad flash? I appreciate all the help btw
[Android Head-Units] Skratchuk:
Ok update I have done a factory reset and still with the same problem no sound apart from radio & mp3 player and eq always resets please any help cos I am running out of idea's.
[Android Head-Units] Skratchuk:
Sorry for all the questions BUT i hope they also help others out too, what is the extra settings password, can I use another equalizer instead of the stock one if so which is recommended, can I turn any of the stock widgets off ie. dvd as It hasn't even got a dvd player or tv?

Thanks in advance
[Android Head-Units] KID52:
"123456", this is stated in the manual.

The only way to change the widgets is to install a different launcher, such as ADW Launcher.
[Android Head-Units] Skratchuk:
I checked out the FAQ first but unless I have overlooked it these answers are not stated hence why im asking.
[Android Head-Units] emutlaq:
Hi guys,

I have a Ford Crown vic and I'm thinking about buying this stereo

But I'm afraid of having a bad sound quality :(

Is the sound quality of this car stereo like the original car stereo ? or it will give me less quality ?
[Android Head-Units] balaes:
sounds good

This type of stereo, sounds good. (very good)
[Android Head-Units] storm83:
I personally think the sound quality is quite good. I have mine in a 02 Trans Am with the stock monsoon amp and it definitely improved the sound from the stock head unit. I also have a JL 10w6v3 sub with a JL HD750 amp for that and the thing pounds. No complaints here.
[Android Head-Units] anpo:
Big improvement over stock radio in a Hyundai Santa Fe -07, unamplified. But radio reception is way worse.

[Android Head-Units] Skratchuk:

[Android Head-Units] jpapadami:
Were you able to root it using the standard method?
[Android Head-Units] balaes:
Sorry, my mistake, is 4.1.1 not 4.1.2
[Android Head-Units] jpapadami:
So there are no problems rooting it?
[Android Head-Units] balaes:
I have not routed, do not see a good reason for that, yet.

Previous version I had routed.
[Android Head-Units] PsychoMcSatan:
Just scanned through the 4pda.ru thread and it appears that the 4.2 image still uses the old 4.1 sdk version so it's probably nothing more than clever text editing. Translations are not 100%, but I think that rooting continues to work so I'd be surprised if there is any substantial difference between the 4.2 and 4.1 versions of 2.7.11.

I think I'll apply that "4.2" version tonight or tomorrow as it's probably harmless. I'm still hoping that it'll finally include the MCU version I require.
[Android Head-Units] jpapadami:
Let us know how it works out. I'm also interested in a newer mcu version. Maybe I'll also jump the gun and test the new firmwares as long as it can be reverted to 2.7.9 without persisting any of the 2.7.11 problems (e.g. USB device message keep popping up like booba5185 was having)
[Android Head-Units] Skratchuk:
OK im fairly new to all this but thought i would show a few screenshots of 2.7.11. Testing now all seems to be working fine (apart from eq keeps reseting on radio) GPS seems fine and launcher is much user friendly and you can choose what you want on the front rather than it all being on there and cannot be changed. I have not rooted it yet as i dare not to as im too much of a novice.

I also tried out 4.2 and i didn't notice ANY difference to 2.7.9.

Any questions or tests you want me to do or pictures let us know.
[Android Head-Units] booba5185:
Just so you know, reverting back to 2.7.9 did not correct this problem for me. Will that be the case for you? I have no clue. I just have to keep an APK of ES file manager on the USB drive so I can install it when I need it and uninstall it when I'm done...which isn't all that often.
[Android Head-Units] jpapadami:
Thanks for the heads up. What unit do you have and why did you decide to rever back? Because of the USB device messages?

This just doesn't make sense. Normally when you flash a firmware version you clean out the eprom/internal memory and everything should be back to how it was. The firmware flashes aren't behaving like other flashes (android, router, video players, etc...) that I have done in the past.
[Android Head-Units] booba5185:
I have the single knob DVD unit, I had to do a factory reset just to be able to root the unit again. I actually had to do it after flashing 2.7.11 both of the times I have flashed it. I'm currently back on 2.7.11, once I set up 2.7.9 with everything I decided to flash 2.7.11 again with a fresh download. I had the same result, but instead of flashing back to 2.7.9 and then doing a factory reset I just did a factory reset with 2.7.11. I was then able to root, but I still can't see in some directories such as the /system/etc/mcu (or whatever the mcu directory is) and /data/. I checked all settings in ES and it was configured to show me everything, I must just not have access to read it or something. When I had flashed back to 2.7.9 then did the factory reset and rooted it again, I could see these files. Why? I don't know. I have not flashed 4.2.2 yet but I plan to, I've just been working on the transmission for 3 days.
[Android Head-Units] jpapadami:
Thanks. I have the same unit. Most of my questions require the unit to be rooted. Maybe one though. Are you getting the USB default prompt message popping up every time like booba5185 was having?
[Android Head-Units] jpapadami:
Since your experience with 2.7.11 I will not experiment with it, but rather try the 4.2.2 version to see if it can be rooted and if the "mcu" and "data" directories are visible. I'll post results as well, unless you beat me to it :). Someone (iI believe KID52) posted that version 4.2.2 might not be a real 4.2.2 but just a text edited of the version as they didn't see any difference. I'll also check this out and install third party app to see what it says.
[Android Head-Units] Skratchuk:
I think KID52 is correct as I did try 4.2 and not a single change apart from the firmware number.
[Android Head-Units] jpapadami:
Actually it was PsychoMCSatan from post #3690. From what he stated, it seems that you can still root it. Problem now is if the "mcu" and "data" directories are empty or not. Can you confirm this if you decide to root? I'll confirm once I get some free time after work to install the 4.2 (2.7.11) verion.
[Android Head-Units] Skratchuk:
IF I root and it doesn't work out,can I revert back easily enough by re-flashing

As for the usb error I haven't had any error YET is this with a flash usb or with a wi-fi dongle?
[Android Head-Units] jpapadami:
Yes, you can revert back by flashing and performing a factory reset. Just read booba5185 post #3695. As for the error, I think it was for a usb storage device.

If you do decide to root, please don't forget two things when following the rooting instructions from the first page.

1. Do not forget to perform step 3 (open and close the AUX application). Many people forget to do this. There screens become black, UIs, keyboards, etc... are visible for a sec and then disappear, and so on. It will just complicate things in which you will have to memorize everything on the screen in order to get to the "reset to factory" settings in Android to perform a reset and start all over again. Keep in mind that flashing won't fix the black screen issue.

2. Install Superuser# (aka com.koushikdutta.superuser.apk) beforehand. Once you get to step 10 and type in "su" you might get a permission denied message. By installing Superuser# beforehand, when you perform step 10 the superuser dialog will appear to ask you to update the binaries, then allowing "su" privileges.
[Android Head-Units] Skratchuk:
Thats what happened to me before keyboard kept going on and off i thought that was normal haha

OK i ill root it today and let you know how it goes.
[Android Head-Units] P1K:
Sorry if this has been clarified elsewhere in the thread, is it possible to run both wifi & 3g dongles simultaneously? It quite happily picks up wifi hotspots whilst driving around town and using my phone as a hotspot to use my data plan, but reception of that is sketchy at best so I'd like to utilise a data-only sim of a different carrier to cover all bases.
[Android Head-Units] PsychoMcSatan:
I believe I saw the issue of directories (like etc/mcu) appearing empty after initially installing 2.7.9. I was using ES Explorer so I tried another Root Explorer (can't remember now which one) and it saw the contents.

I seem to recall someone posting about a recent update to ES Explorer not working for our units so perhaps this is what's broken with it. So perhaps give another root explorer a try.

I'm going to try the "4.2" version in a couple hours and I'll post results.
[Android Head-Units] booba5185:
What version are you running? I have ALWAYS gotten the error with the USB OBD adapter, unless I install Torque Pro as a system app. Problem with installing Torque as a system app is that it opens on boot, not matter what you do. If I don't have it installed as a system app the USB prompt pops up every time I open Torque, but not on boot. Once I went to 2.7.11 (and since then, doesn't matter if I go back to 2.7.9 or not), the USB prompt pops up for a jump drive, with ES file manager being the default program. If I uninstall ES, then no prompt is displayed, so I just keep a copy of ES on my jump drive to install when I need it and uninstall when I'm done.

I started this thread, but I have gotten no help with the problem at all, as you can see:

2.7.11 with 4.2.2? I have all that as well, but try going to \system\etc\mcu and \data\

I don't use the stock EQ. I use Viper4Android which has a MUCH better EQ and other settings, but I only really use it for the EQ. I'm not 100% sure if it'd still apply to the radio though.
