[Q] Re: Samsung Galaxy S2 (l9100) Car USB internal mount

Hi all, I've been waiting and searching around seeing if I was able to find any kind of fix or something for some time now but it's beginning to get to me far too much.
My problem is when I had the HTC Aria I used to have the audio stored on my phone and plug it into my car's USB connection and the headunit would search the device and find all audio to play through the headunit which I was then able to use my controls on the steering wheel. After some time I bought the Samsung Galaxy S2 (l9100) and to my excitement received the whopping 16GB internal storage as a bonus, so I filled that. And heres where my problem comes in, I cant seem to make my headunit search the internal storage and play all that music, It will only search the SD card (external).
Now from reading all over the internet I've been led to believe by any posts that relate somewhat to this that it wont be possible for this to work, what frustrates me though is that it is possible. I've rooted and flashed various custom ROM's to my device (VillianROM first, Cyanogenmod Nightlies second and now MIUI yesterday). I have successfully had the headunit read my internal (newer and more songs) upon connection twice that I can recall now, I think the first time was after first connection to the car after the cyanogenmod flash and today when I first connected it again. Which led me to believe that it was working and then was just applying a new theme on my phone while hanging at a friends then was taking another friend home and plugged it in and back to only reading from my SD card (external - old crap music) and can't figure out why it has worked twice if it is not possible.
The reason why I am determined to figure this out is due to 16 GB internal storage and only 1 GB external storage and I wish to use my phone to its full potential.
While I'm at it, I guess I should mention my other problem which adds to my determination to get the USB connection working with my car. The USB connection is a much clearer & louder playback (Higher quality) then the AUX (current alternative) and to be safer while driving by using my steering controls.
But since flashing to Cyanogenmod and MIUI (cannot recall whether I had this problem on VillainROM) I've noticed the volume in headset mode (when I have something plugged into the headphone jack - ie, AUX, etc) and I begin turning up the volume from quietest to loudest it get notably louder each press until halfway or a press before halfway and then does not become any louder, which I also think may be making the audio less clear and loud when connected via AUX to my car.
Thanks in advance to anyone whom contributes.
I am usually stubborn enough to sort problems out myself, but for the first time I am asking for help on a community forum.

Anyone have any idea what I'm talking about?
If you need to know anything else don't hesitate to ask.

CM7 volume is a known issues or least it was last time I checked.
Try turning on/off usb debugging is my best guess.

Done that, today at some point it randomly read my internal storage and right now I'm constantly reconnecting it with no success.
The frustration continues as it is obviously possible but appears to have a mind of its own.
With my little knowledge when it comes to android and their platform, is it possible it could be there mount priority of the storage or the internal having something stored on it such as an app that could be in use by the phone which could be preventing the drive from being read?

what the hell... I have the exact OPPOSITE problem.
With my headunit its been only mounting the internal storage, but most of my music I put them in the external since I got a 32gb card!
Could it be mounting the smaller sized storage first? =P
-EDIT-
Actually it should be easier to do it the way you want it to (i.e mount internal only)
just unmount the sd card via the android settings -> storage -> unmount
and once it is unmounted, connect the usb to the car.
The catch is of course if you wanna use the external again you have to manually mount it via the settings.

more info but no real help
I have seen a very similar problem and I feel like I can reproduce it.
I've got a 2010 Hyundai Tucson - it has a USB/aux port in the dash console and can accept anything that can be mounted as flash media, flash drives, ipods, etc can all play back music using the Nav display to browse and playback files from the device.
The stereo plays back music perfectly through both my wife's old and new phones. An original MyTouch 3g and a MyTouch 4g. She's had no problem mounting and reading the files from her internal storage. She can playback music on her phone, the car even remembers her place and resumes where she stopped a song.
I, on the other hand, cannot easily get the car to playback files from my older or newer phone. I started with the original android, the HTC Dream/TMobile G1 then later upgraded to a Samsung Galaxy S 3g/TMob Vibrant. What's the difference? I've run modded android OS on my phones and my wife has not. I had been running CM5 and later CM6 on the G1/Dream until I retired it. Lately I've been using a MIUI mod, Lithium 360, on the Vibrant.
When I plug in to the USB on the car, the phone gives me the mount prompt and the car begins searching for files. Eventually both fail to make any progress.
I've tried many fixes including turning on/off USB debugging, I've tried wiping Dalvik cache, Wiping regular cache, I believe I even did a factory reset, flash zip, full re-install on a road trip just to see if I could get the car to read my files. What I did discover is that the problem is simply not hardware related. I could boot to recovery and use clockwork to mount USB storage. Files were seen instantly and played back fine. However, this doesn't do me any good as I can't really use the device for anything else (safety first ) and not to mention that there's no way I want to run the phone with the screen on for hours. I know there are simple workarounds here. But carrying an aux/patch cable is an extra hassle, and since my phone can hold enough data for my average means, I often don't remember to bring a flash drive with me everywhere. Besides, the USB cable in the dash does double duty, charging while giving access to files.
To be fair, I've only used CM based mods (according to wikipedia, MIUI is somewhat based on Cyanogen) on my phone and have not tried out any other android software. I don't know if that's a connection or not, but it's the only lead I have right now. There's got to be something different about the USB settings in the OS itself compared to stock Android. Is there an apk file one could flash and test somehow?

This thread is above seems to be describing the same problem. This however appears to be an aftermarket stereo.

[Q] After mounting it *immediately* dismounts
Connecting to a Samsung TV (USB debugging ON and clicked on USB Storage until it turns from green to orange) and then browsing USB (Menu => USB device) it mounts the USB ("Android 11GB" which is presumably the internal SD) and then dismounts within a second and restarts initializing. An ordinary USB stick (single file system) does mount.
Is this because the Galaxy S2 mounts two file systems at a time and the TV cannot handle this. Is there an app which only mounts ONE filesystem on the Galaxy ?

Good job.
As I see we will have some new updates to our Folio 100. Keep it up.

Sorry, had some troubles with file hosting, as hosting on github is not possible anymore. The files are available now.

thanks, for this download and for this job, !

Thanks DerArtem, Downloading......

Great! Thank you.

Can we change the status bar? I like the old one...

why is it notcould it be running in tablet mode by default?
wake-up sometimes does not work (especially after plugging USB)
keyboard crashes(hides) when typing fixed after reinstall
Oh and thanks o (◡‿◡✿)

Nice work !!
It's a nice rom !!
The rom works smooth.
Also panorama photo works with external cam !!
DEMO of the rom: http://www.youtube.com/watch?v=qz4fNxZkAYo
DEMO of multiple users : http://www.youtube.com/watch?v=hHnKA4BJ83c

Only one word : great
Thanks very much for this 3 years of work, always better and, safe my folio...

Goo.im server Offline! Could upload on Dev-Host?? Thanks
Ok...working again!

Hello DerArtem,
As usual, very good job. The rom is smooth and very responsive. Navigation is as smooth as Nexus.
I hide the navbar since physical buttons still work (expandable desktop). To replace it, Deskbar is good.
The multi-user works very well I configure with Multi-User App.
I did some tests:
AnTuTu: 6369
High quality FPS: 40.4 on Epic Citadel
Played GTA VC, The Bard's Tales but Jet Set Radio did not seem to get started.
The partitioning is great. This is better than 4.1.2, great! We have all the internal storage for data.
The wifi was temperamental in the first start, but he looked into now.
But I often SOD.
It's great to see that you continue to work on Folio. Thank you very much.
Good luck for the future.

USB 3G dongle doesn't work. I have a huawei K3715. In Android 4.1.2 is it working. It is strange I can find nortwork providers and also connect but the internet doesn't work. He said that i'am connected with Proximus (My provider in Belgium). But internet is not working.
Can anyone help me? Or ist it a bug DerArtem?
Sometimes my folio don't wake up from hibernate.
But it is a good rom for the begin of android 4.2.2 !!
GO DerArtem !! You can it.

I read that CM does not have and does not support Tablet UI. It damage not to find the status bar and notification bar in the navbar. It's more convenient, you can expect a small patch homemade?
Otherwise, I tried the 160 and 213 dpi, it works.
PS : The Google translation makes me very scared.

probleem with power button. folio doesn't wake op after 10 seconds or more.
keyboard disappears after keypress. I don't no how to swipe correctly.
perhaps we need a detailed instruction how to wipe the memory completely and further installation, like the one in version 4.1.2
did a reinstall of 4.1.2 and will wait for the next version.
12/3: had to install 4.2.2 again. same problems but found some workarounds. for the keyboard i disabled the automatic text correction. no more sod after installing advanced wifi lock. this way 4.2.2 is great.

Car Bluetooth not detecting my S7

Hi All,
Not sure if this is possible, but thought its worth asking...
I've upgraded from the S6 to the S7 and we couldn't get the Bluetooth to detect in the car.
It doesn't appear in the list, the S6 worked just fine - or so I thought...
I had the S6 originally configured with Lollipop and the OTA pushed me to Marshmallow, didn't have any issues with Bluetooth - until I wiped the S6 to factory settings and attempted to connect my car.
The S6 on MM didn't find the car Bluetooth, I downgraded to Lollipop on the S6 and I was able to detect and connect to the Car Audio successfully. I've upgraded to MM now after being successfully paired to the car and everything is fine with the S6.
I really want to get this up and running on my S7 - otherwise I'll need to sell it and replace it with something else... As most of you are aware MM is the first release on the S7 so I can't downgrade... I tried it on a Nexus 6P with MM, that worked just fine, it might be a touchwiz thing?
I don't think the car is capable of a firmware upgrade to fix this - its a BMW 118i 2008 with the "Professional Radio"
I've searched a few forums - no such luck finding one.
Guys, I'm open to suggestions to try and make this work...
I've tried Bluetooth apps in the play store, no luck so far, I've tried clearing the cache as I've read in a post, I've reset the phone twice...
The S6/S7 is not rooted, not sure if there are any ROMs out there or modem upgrades that could possibly resolve this.
Thanks all,

I am aware you already cleared cache, but just to make sure everything here is tried at the same time in the same run.
Go to Settings -> Applications -> Application Manager
Find Bluetooth and Force Stop it
Now clear the cache and data
Now find Bluetooth Share and repeat the same process
Reboot and start the next section
Now you'll need to make sure you're trying to pair it correctly with your vehicle
Insert remote control all the way into the ignition lock
Switch on ignition without operating the brake or clutch or pressing the start/stop button
Press the Menu button
Press the controller to open the "i" menu
Select "Settings" and press the controller
Select "Bluetooth" and press the controller
Move the highlight marker to the second field from the top, select "Phone" and press the controller.
Select "Pair new phone" and press the controller
Select "Start pairing" and press the controller
The bluetooth name of the vehicle should now be displayed on your phone
That is taken directly from your manual I believe. If that still doesn't work are you sure that you don't have too many devices paired to your car? Try deleting an old phone or two from your car to see if that clears things up.
Also, I do think you are able to do updates for your vehicle.

Xtrons Wifi and Bluetooth issues with PE98MTVPL Octacore Oreo Headunit

I recently purchased a PE98MTVPL, headunit.
Generally happy with it but there are a couple of issues.
1. It initially connected to my wifi, but now it won't even see the router. I started by not re-connecting to the router. I told it to forget the router so I could try and get it to reconnect and now it doesn't even display my router in the list, but it does offer me other people's routers to connect to though. My phone is getting full signal from the router when I am in the van next to it.
I've tried doing a network reset, but it doesn't work - the system retains all the old network information.
I've also tried doing a factory reset and that does nothing at all.
2. I have been able to connect one phone and the ODBII dongle via bluetooth, but it won't let me pair anything else, even though the bluetooth is registering that a device is available.
Again network reset and factory reset don't seem to get rid of anything.
3. The DAB reception is good when stationary both with the engine on and off. But when moving there is loads of feedback whine whenever the steering wheel is turned, which makes it pretty much useless.

What did Xtrons support suggest?

No response as yet. I have asked them the same question. Will post their response when I get it in case it helps anyone else.

So the response from Xtrons was to send me a link to a firmware update file. I've downloaded and tried to install, but the update fails at the 'mcu update' stage. I've asked Xtrons for advice but no response. I suspect the update fail is something to do with how the files are structured on the SD card after I've unzipped them. Any advice?

I have the Xtrons PE88jccpl (Android 8, Octa Core) sometimes the wifi connects perfectly but other times getting authenticating, authentication errors. Also, having problems with the speed when its connected it starts out fast and perfect but slows down to .2 to .3 mbps after a couple of minutes. Xtrons support sent me a link to update and I updated both MCU and android but still getting issues. (I put the img and update.zip on a usb stick and once I inserted it asked if I wanted to update) Not sure if I am supposed to wipe the device after updating android

Sounds like you did the right thing. I've still had wifi issues with my mobile hotspot since the last update so no progress.

Format your SD card in FAT32, then copy the dmcu.img on on your card (nothing else should be on there). Once you pop the card in it should automatially ask you if you want to update. If not go to settings, there is a button "mcu update" try that. If that doesnt work go to recovery mode and choose mcu update.

Yes unfortunately this does not work well on these units. I have tried it with different wifi sticks and different phones, It never runs stable. I ve also tried variuos MCU versions and ROMS (stock and custom).As soon as you disconnect it (eg leaving the car) it might not reconnect (sometimes it does sometimes it doesnt). What helps is to change the password for the hotspot and then reconnect with the correct password. IN that case it somehow goes through the whole registration routine again and almost always connects. But obviosuly thats not a convenient solution. It is an extreme shame that something so simple does not work on these units. Using a 3g stick (not using wifi) works slightly better but still incredibly unfortunate and not understandable that this is not properly implemented. Every smartphone in this world can access the internet through a simcard without any problems:crying:

I recently updated and wiped the android and mcu provided by Xtrons, its reconnecting successfully finally after sleep. However, I am getting speed issues still, after a couple of minutes of driving it slows down to .2 to .4 mbps.

has anyone tried using usb wifi dongle?

Do you mean a 3G/4G plug in one? I've thought about it, but my current phone supplier won't let me have an extra sim. If you mean an external wifi unit instead of the built in one, then no I haven't. The box only has two USB inputs, and one of those is for my DAB+, and the other I use for connecting phones etc. I don't know if it would help though.
The problem seems to me to be something to do with the way the unit is handling IP addressing. I don't know if an external wifi unit would change that. When I gave my the Xtrons unit a fixed IP address on my home router it would re-connect without any issue. For some reason the head unit doesn't seem happy with the IP address changing.

I got TE706PL and the wifi turns itself off I have done the firmware and mcu update and it still does the same thing

Bluetooth not working after OTA update to 10.5.9

I have a OnePlus Nord with unlocked bootloader and stock rom.
Today I updated to OxygenOS 10.5.9.AC01BA via OTA. It downloaded the entire rom (as usual because of root).
As usual, I installed Magisk on the partition before rebooting (As I've been doing for years... it's not the first rooted OnePlus I owned)
After reboot to 10.5.9, my bluetooth isn't working anymore.
It's stuck in a loop where it tries to switch on bluetooth, then off and on again...
I rebooted a lot of times.
I cleared the Bluetooth App data and cache
I wiped the cache partition via recovery.
I tried the bt reset (Settings, System, Reset Options, Reset WiFi Mobile Bluetooth)
Still not working...
I would really like to avoid wiping data :crying:
A logcat extract with a lot of bt errors: https://pastebin.com/urHURjQ8

No problem here, my JBL buds, MiBand and Amazfit, all working fine.

Hi,
Bluetooth is working for me at least on my car.
Android Auto stopped working after the update and USB towards all computers seems to have stopped working
Edit: Wiping cache did it for me

Same problem here. Now cant even disable BT.
Mostly use for mi band4 conection.
Did try some few things, some reserva, BT and data reset settings, at recovery did try wipe cache, but nothing working. Now BT keeps on a cycle of try to BE turned on.
Any advice.?
Can we even do a rollback to 10.5.8?

I'm having bluetooth issues since .9 update too, my jabra 65t keep disconnecting when they worked fine before. Sometimes I can't connect at all either until I restart bluetooth. They probably effed something with the latest bluetooth stability updates.

I'm having issues too with Bluetooth after upgrading to .9
Losing connection with Mi Band and with BT earphones at least once/twice per hour, that's a really annoying issue.
