you are just paranoid.

about the build.prop, whenever a change is made, the system saves the original as a backup. so youll have 2. if you dont want to be paranoid anymore, in twrp or cwm recovery, wipe the system then flash another rom or a factory image. wiping the system will delete any rom or anything that was added into your system. you will need to flash a rom before you could boot up again.

I think getting a new phone will be the most hassle free and likely cheapest solution. Turn off the other phone, take out the battery and you will have nothing to worry about it anymore.

Yes you can go and do al kinds of checks yourself, reset it and have some people look at it. But will you ever be sure that there is nothing malicious left on your phone? Just holding the phone that was once (or still is) infected by your (evil?) ex-boyfriend might bring up many emotions. Please don't lose your sleep over this. Spare yourself the trouble and get a new device.

Maybe it was time for an update anyway :)

Good luck!
[Security Discussion] nutpants:
If it is a good device, give it to me

Or even a crappy one I have a collection of both)

I'll use it

That will mess with your exs mind..
[G3 Q&A, Help & Troubleshooting] greasemnky:
Hi,

First of all, I had a bootloop problem couple of months back but it was fixed by a battery change. I had rooted my phone and then put the stock rom by using LG Flashtool. The Software now is Android 6.0 MM

Last week my phone randomly died on me while I was taking a picture. The battery percentage was 82 and yet it was bootlooping.

I got a new battery and the boot looping hasnt stopped. I tried to do LG Flash tool and LG UP and LG Suite but my phone turns off after a couple of seconds in download mode. I tried Factory reset by using the volume down button but it turns off when the android man appears. Now it even stopped showing percentage while I charge the phone.

I really think its software problem but I am not able to do anything to the damn thing. PLEASE HELP ME! :crying: I am running on a S2 and that thing is grandpa generation! :(
[G3 Q&A, Help & Troubleshooting] jinderation:
This maybe related to a hardware issue take it to a reputable technician u already said it was related to battery ... A swollen battery could have damaged ur g3 internals

The battery wasnt swollen before. It was just not working. But Ill will be giving the phone to technician. Thanks for you reply :)
[Verizon HTC One (M8)] Syrax87:
Hello, I currently have a HTC One M8 and have used sunshine to unlock and s-off, also have used rootking to get the phone rooted and root has been verified with rootchecker. I am new to the whole process of rooting and flashing. I have fastboot setup. I am looking for a good new user friendly rom that is battery efficient. I was looking into getting a venom rom but was told I would need a RUU. Any suggestions on the route I need to go? I am currently on the stock rom and had put the supersu app on my phone but am getting a message that says I need to update my surpersu binaries.

[Android Head-Units] DanB0y:
Hi, I installed a MTCD Android head unit with Android 5.1.1 in my car two weeks ago. (I could'nt start this thread in the MTCD section because I'm new here)

My car audio setup goes as follow: Android Head Unit >>> USB Cable >>> PCM2704 USB to SPDIF adapter >>> SPDIF coax cable >>> MiniDSP 6x8 >>> 3 Amps >>> Speakers + sub.

So far I've been able to get SPDIF sound output with Neutron (Direct USB mode), Onkyo HF Player, USB Audio Player Pro, HibyMusic Player.

Sound is amazing btw.

If I understand correctly, all these apps are working with the USB DAC because they use their own app's USB Driver.

Important to know: All song in 44khz are playing fine, songs in 48khz makes every app freeze. I got a way around this by setting Neutron to resample every song in 44khz, so all songs are working now.

Now, if I play a song in Google Play Music, Spotify, Kodi, etc no sound comes out ... same thing for my HU video app, phone calls etc.

Is there a way around this ? What modifications can be made so every sound outputs to the USB Audio ? IE. kernel update, system files modifications etc ??

Thanks for any input.
[Android Head-Units] DanB0y:
:( Nobody use a USB DAC with his head unit ?

I have found this thread: http://xdaforums.com/showpost.php?p=66707293&postcount=47

But I dont think it applies to Android 5.1, sound management is different.
[Android Head-Units] CadillacMike:
i dont use any DAC on this head unit. But I do have a Dragonfly USB DAC on my computer. the Dragonfly Red says it works with Android. Not sure if that is just marketing, or if it doesn't something specific.
[Android Head-Units] DanB0y:
Can you try it please ?
[Android Head-Units] CadillacMike:
i dont know how I would even go about hooking it up? i could plug it into the USB port, but then what? use headphones?

all my speakers go through the wiring harness
[Android Head-Units] Hisma:
you would need to be using pre-outs, using a 3.5mm to rca cable into an external amp.

---------- Post added at 09:03 AM ---------- Previous post was at 08:57 AM ----------

interesting that you've tried this. This forces you to completely by-pass the HUs sound processing.

I have the same DSP, but I'm using direct pre-outs. I like this idea though bc it gets around the low pre-out voltage, and allows you to ignore the poorly implemented sound processing in the HU.

Unfortunately, you probably need to modify the filesystem to get this to work, as your link shows. Why do you feel the need to use a DAC in addition to the DSP?
[Android Head-Units] CadillacMike:
my sub is tapped into my speaker wires, so I dont use the RCA preouts. So I probably can't try this.

However, I think my audio is pretty great with the Joying
[Android Head-Units] DanB0y:
Yes simply use headphones :)

We just need to know if audio is outputing from the DAC.

I would appreciate, thanks !
[Android Head-Units] DanB0y:
The DAC is a really clean source signal VS the head unit, I have a 2000$+ sound system in my car and sound quality is very important to me.

Also, DAC is digital signal VS analog RCA outputs on the head unit.
[Android Head-Units] Hisma:
I agree. I feel like right now my HU is the "weak point" of my system. I am about the same as you, roughly $2000 in equipment (probably a little more).

focal KRX3 3-way active system w/ a cheap kicker sub + 3 amps. I have the C-DSP along w/ a line driver to manage the low pre-out voltage. Would love to take the line driver out of the signal chain if I could. All these components are taking up a lot of valuable space.

I hope you figure this out. I don't have a MTCD, I have a non-joying 4.4 HU. Would love to use the SPDIF inputs on the C-DSP as opposed to the ****ty pre-outs from the HU.
[Android Head-Units] DanB0y:
Nice ! I have 3 way peerless (tweets + 3.5 mids + 7in woofer) 1 pioneer amp 4ch for tweets + mids and 1 pioneer amp 2ch for the woofers, another JBL amp in the trunk with a 15in Alpine Type-R. I have the C-DSP 6X8 MiniDSp as well :)
[Android Head-Units] DanB0y:
SPDIF to C-DSP SPDIF Input would give you 4V at the MiniDSP RCA outputs :)
[Android Head-Units] Hisma:
well you have convinced me to give this a shot. The USB DAC + 25 ft coax cable only set me back $35 on amazon. So even if this doesn't work I won't be mad.

The potential for 4V of CLEAN pre-out voltage is too enticing to pass up. The line driver works, but like I said it's another box that needs power/space/etc. The USB DAC also allows me to take the HU sound processor fully out of my signal chain.

I am unfortunately using android 4.4, so dont think I can help you much, but I will let you know if this works nonetheless.
[Android Head-Units] DanB0y:
If it dont work natively, I'm 99% sure it will work with the Neutron music player. Install it and then go to hardware settings and enable Direct USB Driver. :good:
[Android Head-Units] Hisma:
well I tested this today and I am very pleased with the results. I really do notice a difference in SQ. It sounds "cleaner" and fuller.

Only major thing I notice is the overall volume seems really high over SPDIF. Only place I can adjust the volume now is with the DSP, but even then, I find I need to turn the gain down on the SPDIF inputs to get an acceptable volume. This is even with gain all the way down on my amps. This leads to a bit of clipping on the highs.

Did you make any adjustments in neutron player or the DSP to get an acceptable volume? Or do you get by with just adjusting the DSP master volume?

Now I just need to see if I can get all my sound to route through. I like to listen to streaming music too but I don't think I can go back to using analog pre-outs.
[Android Head-Units] DanB0y:
Great ! Now you're in the same boat as me lol

(Except for the clipping, I have no problem with that)

What is the model of your amps ? I have my gain to around 1/3 in the amps (They're up to 6.5V input sensitivity) and spdif input gain is at 0.

For your sound routing, you can sum the rca inputs and the spdif input together in the DSP :) And then you use your input levels to match the loudness. That way, you'll be able to listen excellent SQ music from Neutron and still hear BT phone calls, Youtube, navigation etc trough the analog inputs.
[Android Head-Units] Hisma:
Yes! This is exactly what I have done. I spoke too soon also. The clipping was more a tuning issue than anything (changed cross-over on tweeters & lowered their output a bit). I was able to set the gain on SPDIF back to 0.

Man it sounds really good now. I haven't any real tuning yet outside of setting gains and cross-overs. I think once I tune the system it'll take it over the top.

I have a mosconi as100.4 on the tweeters and mids, and a alpine mrv-m500 on the sub. (i have one other amp I am replacing to power mid woofer, should arrive tomorrow). It's a total overkill system, but I find great deals on used gear on diymobileaudio classifieds so I keep upgrading lol.

So now I will use neutron for majority of listening, and by mixing channels together on the analogs I already had connected, I get acceptable SQ for phone calls and streaming music. I have no desire to mod my system files the way it was shown in that thread you linked. Looks too risky. I am okay with this new arrangement since 90+% of my listening is my personal music collection.

Really appreciate you making this thread. I always knew my system was capable of sounding better and this did the trick. I will let you know if I figure anything else out that could be useful.
[Android Head-Units] DanB0y:
Yeah I know what overkill sounds like haha

For frontstage 3way I got a 4ch Pioneer Premier PRS-X340 running 2x NE25-VTS04 Peerless tweets and 2x NE95W-04 3in Peerless mids, another Pioneer old scholl amp pushing 2x175w for 7in Wavecor woofers. In the trunk is a JBL GTO14001, 1500Wrms @2ohm pushing a 15In Alpine Type-R sub in 3.5cuft tuned [MENTION=5723170]21h[/MENTION]z

All my amps are very good condition used gear found on classifieds too, you can dig some real treasors for very little money sometimes !

I've been looking all around the web since last week for how to route every sounds of the HU to a USB DAC, translating and reading about 500 pages worth of XDA/Russian Android forums, spent last nights editing config files all around my HU System folder, I tried the how-to link I posted in OP for MTCB units, nothing to do.. I really think the Kernel must be enabled for USB Audio for it to work, my DAC shows up in USB devices info but not in the audio output devices.

Well, I'm still happy because my FLAC music collection plays incredibly well :D i dont car that much for FM Radio SQ, I only wish I'd be able to listen to Spotify or Kodi on the DAC.

Im r eally glad if I could be any help to you and will keep this thread updated if I find something !
[Android Head-Units] modream:
navigation guidance voice goes through usb audio ?
[Android Head-Units] frankienones:
Any update on this thread ?

I made some sort of experiance, on Joying HU , the 2GB Rockchip Sofia version (10.1" screen) :

Using info from https: // source.android.com/devices/audio/usb.html - i looked into the "audio_policy.conf" file on the Joying, and for sure , there was no reference to any USB audio interface.

I am no android expert .. but i edited this file , with the info gathered from the link above , and after a reboot - the HU did indeed send the audio to the USB port.

Audio from all the apps i tred , was routed to the USB interface (Radio , DAB player,Kodi etc..)

The bad thing (?) - there was no volume control , all audio is at max level.

An external volume control could possibly remedy this.. i will look into it

Frank
[Android Head-Units] WILD9:
This is very interesting, hope someone cleverer than me can pick this up and run with it, if volume control could be implemented this could be a break through. I assume radio and Bluetooth output still don't work through the DAC though?

edit:

You mention the radio (analogue?) does work, that's surprising, what about Bluetooth phone calls?
[Android Head-Units] frankienones:
..sorry , haven't tried yet :o
[Android Head-Units] WILD9:
From reading around the subject it seems DAC compatibility with Android L and onward devices is a bit hit and miss depending on the host device and the DAC. I've seen several cases where certain combinations of device and DAC function in the way you describe with no volume control and many where the volume control works properly so it may just be a case of trying different DACs. What device are you using?
[Android Head-Units] DanB0y:
Hi Frank,

Could you copy/paste the content of your audio_policy.conf file here ?

Thanks :)
[Android Head-Units] WILD9:
This one seems to have a good reputation for the price and I've seen a couple of reports of volume control working on various devices.
[Android Head-Units] AssassinsLament:
Thanks for the tip on this one guys, I did the same and my UCA202 works with my joying also, except for the volume part too. The thing is, if I change the volume on the system with a remote, in the settings, or something other than the volume knob, the sound does lower and go higher, but soon after, the joying takes control of the volume again and turns it all the way up to max. My initial thoughts are that the volume knob is directly wired to the outputs on the back of the joying, and thus it doesn't use the system's volume settings. The joying software basically takes control of the system's sound levels and limits us from manually changing the volume without the volume buttons or knob on the headunit.

I'm thinking there might be a way to intercept volume knob turns and apply them to the system's volume controls.
[Android Head-Units] WILD9:
If that's the case then this thread might be an appropriate place to find the solution as the modification is intercepting and redirecting button inputs.
[Android Head-Units] AssassinsLament:
Yep, I thought the same. I'll have to message gustden and see if there is any volume commands being sent. There should be because you see an on screen volume indicator when you turn the knob, also the SystemUI has a built in volume icon on the taskbar that controls Joying's volume also.
[Android Head-Units] WILD9:
Out of interest have you tried the DAC with bluetooth?
[Android Head-Units] AssassinsLament:
No I have not.
[Android Head-Units] kampfschachtel:
the volume control issue sounds to me like a problem of who is controling the USB stream: Joying or DAC?

Would be interessting to try an asynchrone USB DAC as it will take over the control and the timing.

Another source for the issue can be that some DAC's are using analog volume controls but some are using digital volume control. Difference is the analog volume control happens

after

the DAC has transfered digital to analog, means the analog output signal is modified in the level but digital input is continous and steady in level. The digital volume control reduces the level of the digital input signal means the level/volume control is done

before

the DAC and the DAC's analog section is just amplifing the input with a fixed output factor.

To me it looks like the USB-DAC first takes over the volume in a digital way (volume gets reduced by reducing the digital input signal), volume gets effectivly reduced and then joying unit takes over the control and delivers a continous digital signal (as it has analog volume control) and the input of the digital volume controlled DAC gets the full input level which gives you the max. volume output level. Looks like an asynchrone DAC (which takes over the control of timing and USB stream permanently) with analog volume control would be the way to go/solution.

Normally the small form factor and cheaper DACs are using digital volume control as cheaper to realize (reduces number of parts needed) and therefor also smaller, more expensive ones use analog volume control as you need a real preamp for this and it doesn't reduce the dynamic range of the signal as digital volume control does.

Would try myself but I am in hospital for next 3 weeks...

I think what frankienones did was add missing usb area to his file. Yours already has that. Maybe what you need to do is change the default?

default_output_device AUDIO_DEVICE_OUT_SPEAKER

to

default_output_device AUDIO_DEVICE_OUT_USB_ACCESSORY

(or maybe AUDIO_DEVICE_OUT_USB_DEVICE, not sure which, you have both listed in your file)
[Remix OS for PC] Regnas:
Anyone tried it?

I mean, can I use my old data.img with this release?

Cheers...

Thx...
[Remix OS for PC] HypoTurtle:
I did. I cleared some stuff from data.img though - not sure what's needed - as is sorta stalls.

From ALT@F1

rm /data/dalvik-cache/ [to remove dalvik-cache; it would probably be auto cleared anyway]
cd /data/data
for line in `ls | grep [b]com.android[/b]`; do rm -rf $line; done
for line in `ls | grep [b]jide[/b]`; do rm -rf $line; done
[this should clear data from stock android and jide apps]

It's probably just 1/a few app causing the stall; but clearing the above shouldn't do any real harm.

EDIT: Oh and you might need to disable setupwizard [I don't think it's a dirty flash issue though]; I'd try to go through setup maybe twice; if it errors and blackscreens; then if needed run pm disable com.jide.setupwizard to circumvent it.

Hello everyone who is going to read this. So I have this old HTC M7 (Att and unlocked) that I need to put a new ROM on. However it has been about 3 years since I have done this. I moved to Germany a couple years ago, got a phone here and decided against messing with anything at the time. Well bad things happened with water and now I need to use my old phone.

I am not sure what kind of info will be needed but I will give as much now as I can from the "About Phone"

CyanogenMod version 11.0 installerXNPQ32

Android Version 4.4.4

Build Number cm_m7-userdebug 4.4.4 KTU84Q InstallerXNPQ32P

The phone was recently wiped and had some random apps put on just to be used for games or whatever but now I need it as a phone.

What I basically want to do is flash a new ROM that is more stable. However I have no idea on how to do that and the way I did it before is not a good way to do it now? Honestly I wouldn't care but my plan isn't due for renew until March. Any help I can get would be greatly appreciated and if I have posted this in the wrong area I am terribly sorry.
