New Firmware

Came from Rusia
[Android Head-Units] PsychoMcSatan:
My guess would be that the copy of the files that you have may be corrupted. What version are you trying to install? Try to download again or try a different version.

Or actually, try the reset-image that I posted a while back:

http://xdaforums.com/showthread.php?p=53129286#post53129286

It could be that your file system permissions are blocking the install so this should fix that. After running this one, try a regular system image again.
[Android Head-Units] jpapadami:
Thanks. Can you post a link to the forum or where ever you got it from, so that I use Google translate to determine if I can find any changes made in the firmware?

Updated and rooted fine no difference noticed atm and no new MCU at least not for me anyway and eq still resets on radio. For those that root when it comes to the step of using emulator if you go to aux and exit the keyboard will not keep blacking out making it MUCH easier to finish root.

[Android Head-Units] Skratchuk:
I choose the first model on the list but someone did post a zip with all the latest MCU files.

I can not update the normal way, when I do give it to update, it does nothing. Someone said that the only way is by choosing the model works.
[Android Head-Units] digitaldr:
My only reason for updating to the latest firmware was to get the new radio skin. I wonder would it be possible to use the new radio apk with the previous firmware version and have a working equalizer? I had already changed the radio skin to the one posted on this thread but prefer the new official one.

Are you sure you've unzipped the files? The full system images should have three or more files while the system reset image is just one file named 8f1149c0-ea4a-11e2-9029-000c29ba27c0 with no extension.

not going to happen. the mcu can update but the system can not update
[Android Head-Units] Skratchuk:
I once had that problem I done it manually in the end by pressing reset button in and power button which forced update.
[Android Head-Units] sciallo:
Just to clarify for everyone, the "stock equalizer" is another "remore control" app to the mcu, it communicates with the BD37534FV Sound Processors with built-in 3-band Equalizers chip through the mcu (read MCU Explained WIKI page if you haven't yet). Essentially that app is our only way to change settings at the hardware level, like knobs on a old school radio would. Anything else is going to be "on top" and a software "thing" rather than hardware.

I'm surprised that Viper is able to change the sound for radio and other "native apps" since I didn't think their audio went through android at all (in fact you can hear radio while booting and before android is up, and my live wallpaper does not respond to sound from those apps...)
[Android Head-Units] Skratchuk:
Cheers for the info, do you know if it is the MCU version causing the eq reset problem on radio that people are having or is it the stock radio app?
[Android Head-Units] sciallo:
I was wondering that, but I cant say for sure... I would think it depends on wether the settings stay in the mcu or BD37534FV itself and the app reads them and displays them (as I think should be the case) or if it's stored in android.

I wouldn't doubt it...
[Android Head-Units] juninyo:
I have not updated. I have the model that has two radio buttons, one volume and one for radio. I've tried with the device power on, I pressed both reset and the power button (on the left). I also tested with the device power off and simultaneously press reset button and button on. It does not work, get the message update on update off and not updated. No longer do that. thanks for the replies.
[Android Head-Units] Skratchuk:
It might be different to force update on your device best thing to do is search the thread if I find out I'll let you know.
[Android Head-Units] sciallo:
If you get the message "Starting update" (or similar) you're succesfully starting the process, but the radio isn't able to find valid files on the card. Either files are bad, try re-downloading uncompressing, chacking MD5, or the card is formatted weird/flakey/defective, try a different card if you can, I find an old 2gb card that came with an old phone works best. Or try repartitioning/formatting the card.

Overwriting system apps

Thanks for the file. I've tried "replacing" stock apps in the past with no success as of yet. I must be doing something wrong, because the file you provided did not fix the red text issue and I doubt that the file you provided is the problem.

Yes, I am rooted. (I verify after each firmware update using root checker) I use ES File Explorer and also Root Explorer. I download the file on my home pc. I extract the rar/zip and email (gmail) the apk to myself. I go to the car and check my email, download the apk, check my downlooad folder and select it (long press) and choose "copy file" and go to /system/app (I get a pop up saying access granted to super user, or something like that) and select "paste file" and get a "success" message.

At this point, is it necessary to install the apk or just leave it as overwritten? (I chose to install) and get another "success" pop up. I reboot and still see the red text. In the past I tried to do all of this with the radio app and all of the results mentioned above were the same. Do I need to do something else, like mount the partition with certain permissions or something?

I would like to skin some apps too, but haven't because it seems pointless if I cannot overwrite a system app.

Thanks.
[Android Head-Units] PsychoMcSatan:
I think that I read over there that they fix it by going back to a previous version of MCU, either 4.2.13 or 4.2.15. Though I think it was also mentioned that the sound quality was better with the 4.3.1 MCU.

As has been mentioned a few times, the translations are very awkward and I'm not sure how you could search so take my interpretation with a grain of salt (it's idioms like "grain of salt" which mess up the translations... so take that, Russian who's trying to translate my post!!!)
[Android Head-Units] Skratchuk:
Ok thanks for the info m8 I'll have another mess with the MCU and see if that sorts it but could possibly end up with the no sound problem on android apps again.
[Android Head-Units] PsychoMcSatan:
That's where I copy it, though I don't install, just copy. It should say that you are overwriting the existing version.

I have not tried this recent modded .26 version, but the .11 one worked for me.

I am getting a sense from various issues being reported that file system permissions do get messed up a bit on these units, likely due to haphazardly compiled images. Which is why I think they (Tonghai Create?) compiled that little system image file which I uploaded with a previous post. It seems to do a more complete reset than the factory reset function in the settings. I know I had odd, blank directory issues which were fixed by applying that image.

It's in this post:

http://xdaforums.com/showthread.php?p=53129286#post53129286
[Android Head-Units] Skratchuk:
When you go in to system/app folder do you see all the files inside it or is it empty?
[Android Head-Units] PsychoMcSatan:
You can apply any system image you want, though I don't think we have a definitive answer about whether the history of system versions installed leaves traces. As for MCU, you can go forward and backward with versions as well.

---------- Post added at 09:46 AM ---------- Previous post was at 09:43 AM ----------

So I've searched for this as it sounds like it should make rooting a little quicker, but I can't seem to find 2.3.9. I tried the download link off the main app website and it gave me some "2001" version.

If you have the APK which you've used, would you mind uploading or sharing a link and I'll give it a try.
[Android Head-Units] tdt038:
What type of the unit do you have, universal? If so, then install the latest firmware 2.7.26, and then install MCU 4.3.1-1-10-2101 ( Settings > General > Extra settings(pass 123456) > Model choose > "VW(4.3.1, RDS, Color, Rohm37534, TEF662X)" )

If you can see the files must mean root is working only thing i can suggest is to delete explorer from su and go copy the apk again and see if it asks you to confirm root again.

I have sorted the eq problem by trying loads of different 4.3.1 MCU files andimm not sure if I had the wrongMCUU from the beginning but my eq no longer resets and my sound quality is much better too.

Quick question for those of you using Poweramp:

Is there a setting or any way to set poweramp to pause music when going into standby?

I have "shutdown delay" set for 30 min. and when I shut the car off of course screen goes off and sound goes off, but if I restart for example 10 minutes later, poweramp seems to not have paused music and it's playing a song 10 minutes down the queue. Are you experiencing the same? I don't think I remember this issue ever reported, but I have CRS disease :rolleyes:
[Android Head-Units] bwthor20:
Are these worth it?

Honest question...I'm really tempted to pick one of these up, but it seems that they just aren't quite ready for prime time. I realize the thread I'm in is full of people that are trying to get the most out of the units, and those that are tweaking them to get them to work the way they want them.

I just don't want to be spending every trip in the car troubleshooting the technology.

For those that own these, what is your overall satisfaction with it?

Also, I know there are a small handful of slightly different variations with these, but does anyone know of any comparisons that have been written up anywhere?

The one I'm leaning toward is this one...

http://www.ebay.com/itm/HD-7-2Din-C...Video_In_Dash_Units_w_GPS&hash=item27e40356a8

Or I might go with one of the Ca-Fi Dashlinq4 systems.

I'm at the information overload stage right now, so anyone willing to help clarify the differences or have a recommendation, I'd greatly appreciate it.
[Android Head-Units] Skratchuk:
Mate the one you have linked to is the one I have, as for troubleshooting I am like that anyway if you set it up and leave it should be ok but do recommend rooting it. I had a pioneer before and I can't believe how good this step stereo sounds especially with viper installed that's why I recommend rooting and if you do need help your in the right place.

Overwriting System Apps

UI not authorised. Please contact the seller

2.7.26

Still cannot get it to work. ES File Explorer shows /system/apps as empty. Root File Explorer shows all of the many system files. I removed both explorers from "super user" as suggested and it did again ask permission. slected allow every time. When I access the folder it pops up "su access granted" and when I paste the file (first it asks if I want to overwrite an existing file & of course I select "yes") then I get confirmation of success and then again the pop up "su access granted" (as if it was temporarily not allowed) and the file has not changed (the date of the file still says 06-02-2014)

What is the point in having my system rooted if I cannot overwrite files in the root directory?

Why would the system inform me of a successful copy/paste operation when it is a flat out LIE!

Do I need to uninstall/re-install the file explorers? I shouldn't have to.

Like I said earlier, Root Checker verified root. SU logs are full of "access granted" entries.

I have an obdII to usb. Im trying to connect it and run torque pro but cannot connect with car. I run Torque Pro 1.8.16

Is there some adjustment i have to do (except the input method to usb witch i have done)?

Or do i have to find another version of torque pro?
[Android Head-Units] MFKinSINY:
Ok. I hit menu, then select settings, the scroll toward the bottom. I see I have checked "access up to root" and a few lines below that is "root file explorer" so I check the box (beneath that, greyed out is "mount system as r/w") a dialog pops up with a bucnh of crap about "try this feature" so I select "yes" and "access granted to super user" pops up. 3 seconds later "test failed, cannot use this feature on your phone"

I double triple check with root checker, and I check "allowed" apps in super user and all indications are positive. I checked for a new version of ES but I have the newest.

Maybe something is corrupt? Maybe I should try yet another file explorer? (but I have my doubts due to the "cannot use this feature" pop up in ES and the false positives with root explorer.

Thanks jpapadami, but do you have any other suggestions.
[Android Head-Units] jpapadami:
What version are you using? I'm using 3.1.5.3. What you're explaining is something that I have never done before with ES file explorer. Don't select Settings after hitting Menu. When you click Menu, a vertical menu appears to the left of the screen. There click Tools and it collapses a whole bunch of other options (App manager, Download Manager, System Manager, etc...). Scroll down and there is where you click the Root Explorer button to turn it on and then click on the text to open up the dialog > select Mount R/W > select the 3 paths to RW.

Other option is to uninstall ES File Explorer, press the reset button with a pin, and then install file explorer again and give it another try.

Do our units have a built in compass? When I load up Google Maps the blue locator always points north when I don't have a navigation waypoint, which leads me to believe it doesn't have a compass.
[Android Head-Units] Skratchuk:
Not sure tbh but I would think the gps would do the same job as a compass.
[Android Head-Units] Blaylock1988:
The compass helps increase the accuracy of the GPS so it correctly represents your travel when you make quick turns or don't make other turns at low speeds. It also helps with starting a new route before drivi g because it knows which way your car is pointing and adjusts to nearby roads accordingly.

I sideloaded it months ago from theone extracted off of my nexus 7. Which, when I hit menu, a bar with options popped up from the bottom, not from the left like you stated.

v.v.v-a-bb(b)-ccde.zip

This is totally awesome. I definitely appreciate this and your efforts in compiling this info.

My original MCU (that came on the unit, which is visually identical to the one pictured at the head of this thread) was 4.0.6-1-10-0101

I somehow ended up with 4.2.13-1-61-2101 (somehow, meaning trying different MCU's & picking different models)

My car is a 1999 Infiniti Q45, so the bb(b) digits bear no relevance for me. The HW rev digit, I'm safely assuming I should maintain at 1 (to match the original #) Mine is a 2DIN, so I should be ok with -0901 (if one exists) and apparently no other features are applicable for me except RDS. In regards to the "cc" digits, are they binary or bcd (is 2101 equal to 0001 0101 d0 e1 or equal to 0010 0001 d0 e1) I'm guessing BCD because I have the color option, even though it doesn't work, otherwise with 2101 with binary I would not have color option (the color app wasn't there before I changed to 2101 from 0101) that being said, I could change to 0501 and hopefully discover what AD is (if I don't brick the unit) but since there is no 0501, I would go with 4501 and ALSO hopefully discover what BC6 is.

At the very least, I need to make sure my last two digits stay "01" so I have the correct chips identified. (I heard mention of sound quality changing when some people changed MCU's and now it makes sense, and also radio presets not sticking)

You already stated that you DO NOT know what all the features mean or do. Do you know any? I'm interested in bits 1, 2 & 6.... (Sleep, AD & BC6) The rest are pretty much obvious.

Thanks for all of your hard work & thanks for sharing!!!

That was my thought. I'm downloading one of the files now to take a look, but it's saying it'll be over an hour :(

I doubt I have the skills to "crack" it, but I'm very curious about the whole thing. It just seems so strange.

Edit: Might pay to add some notes to the wiki identifying this model and the new thread - if possible, upload a photo aswell (not that I can say anything - I've not done either about my unit on there yet).

Edit2: File finally finished downloading, and I'd had a quick look. Beyond my skills I'd say... I can spot the obvious (MCU is the 65k, main filesystem is the big file) but that's where it ends. Chance of me succeeding at working anything else out is somewhere between 0% and 1%. I'm leaning towards the 0% :p Encryption isn't really my thing.
