[General Questions and Answers] Joe_206:
Hi guys, so i have a tricky situation:

I'd like to buy and install StarWars KOTOR from the playstore - however it says, my device isn't compatible (Galaxy S4, Jfltexx und Cyanogenmod 12) - however, seeing all the other devices which ARE compatible, i'm 90% sure, the app would run fine.

Now i've heard you can alter your device-identification over the build.prop and "fake" being for example a Galaxy S3 instead - and then buy and download the app. So far so good.

I just wonder what will happen when I change back to my original build prob? Will play-store interfere or crash or cause any problems? Or would i just see the app normally and could download updates (or even uninstall and reinstall the app) then?

TL;dr: What *would* actually happen if i manage to install an app on my device which is listed as "not compatible"? How would the play store react?

Best regards,

Joe

[General Questions and Answers] Relican:
Hi.

I was wondering why i can't find anywhere info about changing parameter of voltage battery is charged to. Closest thing were tutorials about decompiling, editing, recompiling kernels by using linux only programs. This seems bullcrap (and unnecessary work) because there are a lot of (root requiring) kernel settings editing apps. I found this file (i tihink) i was looking for and i read on the net that this folder is created anew by kernel when phone boots.
[General Questions and Answers] Droidriven:
OK, here's how it goes.

Your kernel is what allows your hardware and your software to work together.

Your point about the kernel building/modding software being bullcrap because of the existence of kernel auditing apps is off base. Here is why, when you use one of the root apps that allow you to change various kernel settings it is tweaking the kernels "effect" or value that is already preloaded in to system, the loaded running value is what gets tweaked, it does not in any way change anything about the actual kernel "itself".

That is why using the "bullcrap" software is needed, because the kernel itself is what needs to be modified, not its preloaded running in system values and settings.

Your battery is a piece of hardware, your device has software that controls and regulates the battery, and the kernel is what controls how the software controls the battery

This means if you want to bring your battery and its controlling software together in the way that you want them, then you will have to modify a kernel or create a new one in order to achieve the result you want.

Even if you find apps that allow you to fool your system into doing what you want, it will not actually be changing anything and it won't truly yield reliable results. Some things you just have to build from the ground up instead of layering on top.

Kindle Fire 1 GEN on 6.3.4

is this device able to be rooted for the system version im on?
[General Questions and Answers] xunholyx:
The reason it says it's not compatible is probably because it won't on your device. Changing the build prop might work to install it, but it won't make it work if your device isn't compatible.

That being said, it might not be "compatible" because of the last official Android version for S3. I assume you are not running official firmware (hehehe), but it also could be and probably is because the hardware isn't good enough to run the game.

I say give it a shot. Why not? You can always uninstall it and change your build.prop back.

There is an official CM 13 rom for my device LG D722, but mine is actually is LG D722p the only difference between the devices is the camera, mine being 13 mpx and the rom's 8 mpx, obviously the only thing not working for me is the camera, when I open the app sends an error message "can't connect to the camera"

Is there any kind of 13 mpx CM 13 camera I can flash or any way to modify the rom to make my camera work?

Thank you very much for the answer. Does it mean there are no android programs that can tweak stuff i need changed? Do you know any windows programs which allow me to modify my kernel?

Apt-X

So I have a T-Mobile Galaxy S5 (SM-G900F) running Phoenix Rom 10.2 Lolli, and I just bought a pair of Apt-X compatible LG Tone Pros (HBS-760). My question is that as far as I can tell, both devices are Apt-X compatible, so do I need to turn it on? Is it always on? If so how can I tell? I'm kind of an audiophile, but due to my job I require bluetooth headphones. Any help would be appreciated. Thanks in advance!

Where do you have the ROM/kernel from? Did you check what works and what doesn't?

Also check if your camera actually works.

I believe it mean you have 2 choices now (my concerns):-

1. Send your device to repair

2. Google/search in XDA by

[General Questions and Answers] Droidriven:
Find a good 3rd party camera app from the playstore. The camera is an issue on all CM builds initially because stock camera source doesn't get released, the devs have to build a camera app from scratch and usually takes a while if they ever figure it out, sometimes it doesn't get figured out. Using a 3rd party camera works to correct the issue on a lot of CM builds.

---------- Post added at 11:00 AM ---------- Previous post was at 10:58 AM ----------

I wish I could say Linux was easy but its nothing like windows, it requires a certain amount of programming and coding knowledge.

There may be mobile apps that can do some of that but PC Linux/Ubuntu is your best bet because you won't be able to do all of it with apps, you'd eventually have to use Linux either way so just start with Linux and forget about the apps.

You can also focus on getting cygwin working correctly.

You can use Linux in VM in Windows with VirtualBox by Oracle.

Thanks for the reply, although this only half worked as only detects front camera, it would seem as if the phone only had this camera, I did the try with a few apps including Instagram, Google camera and a couple others
[General Questions and Answers] Droidriven:
Yep, that's how it usually goes, every device that I've had to use a 3rd party camera on in CM was like that, one of the cameras wouldn't work or if it did the aspect ratio would be wrong and the image would be stretched. Try A Better Camera, try as many different camera apps as you can and find the one that works best, probably won't completely work but its better than nothing til your devs figure out how to patch a stock camera together correctly.

---------- Post added at 12:12 PM ---------- Previous post was at 12:11 PM ----------

I guess it would depend on whether that function was incorporated in your ROM. Try asking your ROM thread so you can get answers from fellow users or from the developer of your ROM.

You probably have a locked bootloader

stock or custom Recovery?

Sent from my SM-A500FU
[General Questions and Answers] Ultimatesaber27:
Well, if i understand right, the JTAG is something that has to be purchased (i thought it was a cable or something built-in that has to be moved so the phone could turn on again. Everyday we learn something new!). If that's the case, it would be better to send it to repair, since i have zero experience with hardware and i fear that i'd make things even worse.

Tell me something, if the device is unbricked, it would still need an operating system right? Because i think that right now the device has nothing to boot.

Other thing, how do i know that the device is either soft or hard-bricked?
[General Questions and Answers] Droidriven:
If its hard bricked it won't charge, no led, no vibrate when power on, no boot to any mode, no connect to PC, just nothing, completely unresponsive.

Have you looked into booting an .IMG from extsdcard, some devices can be booted if an sdcard is converted to a bootable .IMG.

Phone stuck in loading

Was playing around with my new LeTV x600/S1. Installed a new bootloader, TWRP, got chinese version the first time so tried another one. Now phone wont load into bootloader and phone wont boot its Rom. It just keeps loading the EUI logo of the rom. Any ideas?
[General Questions and Answers] Ultimatesaber27:
Well, the device is basically as you said. The PC sounds when i connect it, but it won't show anything from the phone itself (internal storage, sdcard)

And no, it's the first time i heard booting an IMG. But considering the situation, i pressume that wouldn't be possible, since it's completely unresponsive
[General Questions and Answers] Droidriven:
If you're getting the sound when you connect to PC that's something, go to device manager on PC and see what device manager is listing your device as.
[General Questions and Answers] xdvs23:
Have you tried an USB-Jig? (Sorry if that was answered already) It is just a little piece of plastic with a micro usb port and a little bit of metal inside.

You just plug it in and your device should boot into download mode. (only works on most samsung phones and maybe on some others).

Also check if you have the correct drivers installed.

---------- Post added at 09:33 PM ---------- Previous post was at 09:33 PM ----------

That's absolutely right. Maybe some drivers are not installed.

Did you try flashing your device in this state? Does it get detected by any program? Have you tried to just pull out the battery for 20 minutes, then put it in again and pressing all buttons for a minute (power, home and volume rockers) simultaneously?

Maybe your device is eMMC-bricked.

That is, when a device doesn't power on anymore in any way and you only get an unknown device or a preloader/bootloader/SoC device.
[General Questions and Answers] Droidriven:
I can't remember where I found it but there is a package that installs drivers for all LG devices, it should have yours in it.
[General Questions and Answers] Ultimatesaber27:
Yes, i've tried it. The program then keeps waiting for me to connect the device, when it's already connected. Didn't tried the battery thing, better do all i can before giving up hope.

Which then requires a JTAG/RIFF to "possibly" revive.

I have a Samsung Galaxy SII plus, there's a game called "Trial Frontier" and the Google Play store didn't show it 'cause it "wasn't compatible", so I installed it from an other store and it works perfectly, it's probably just because the developer didn't said it was compatible, but it was.

Well, the second link has my phone's drivers, so i'll look into it right now
[General Questions and Answers] xdvs23:
Well, normally the eMMC is write-protected after an eMMC brick. The best solution might be to replace the eMMC and maybe the IC chip, too, and flash the software on it. Maybe SD-booting works but don't know. You can let repair it (if you have manufacturer warranty. Doesnt matter if it is rooted or not). They would replace the needed parts to get the device to power on. Then they send it back without replacing the eMMC because your device is modified. Then you can try to flash something and if it doesnt work... Well, don't know. That's my experience.
[General Questions and Answers] webster-sd:
It wont boot into TWRP, when I use volume up + power it gives another boot icon that would idicate it should boot into the bootloader. But then it goes black and boots into normal mode. At normal mode and connected to my PC, ADB recognizes the phone. BUt cant do anything because it says unauthorized...
[General Questions and Answers] Droidriven:
You may have to reflash stock recovery.
[General Questions and Answers] webster-sd:
But how? I cant use ADB for it and I cant get into the bootloader (TWRP), is there a way that I'm missing?
[General Questions and Answers] Droidriven:
If you're device isn't completely bricked then you can still get it back, the way you do it is going to depend on your model number.
[General Questions and Answers] Manuel15:
If you want to do it, you can also use an app called Market Helper, it doesn't change the build.prop, but manage to make the play store think your phone is another model or another device

Download link http://codekiem.com/2013/02/13/market-helper/
[General Questions and Answers] webster-sd:
You mean the unique model number? Thats the code ADB describes as the list of attached devices. I always thaught it was possible to get into the, sort of bootloader of the phone. From there you could go to the bootloader or to fastboot. Or is that just phone dependend? (Had a HTC One)

Connection problem

Greetings,

US Cellular Samsung Galaxy S4 SCH-R970

Dell Inspiron 1521 Windows Vista 32bit

I have searched and read to no avail of my own accord. I can't get the device and pc to communicate. I have read a ton of information from many sources. It seems that I have a common problem and i have tried every fix that I have read and I still can't make this work.

When I plug it in, I first get a message on the device "connected as media device" in the notification bar at the top of the screen.

Then Windows tries to install device drivers. Next I get a pop up window on the device; "Attention - Unable to find software on your PC that can recognize your device. Service pack 3, Windows Media Player, version 10 or higher, for Windows XP or Android File Transfer for Mac OS must be installed.

You can download and install PC Kies from (link to kies) in order to sync data with your device, back up data, and upgrade your device (Windows and Mac OS are supported."

After that the device driver installation fails trying to install MTP from Windows Update and that's as far as I can go.Same outcome with the PTP method. The phone will charge but nothing else. There are many fixes available and I have tried all that I could find. I have tried the factory USB cable as well as 2 others that have worked on other phones. I have tried all my USB ports, I have 4, 2 on the rear and 2 on the side. I have tried deleting upper filters entry in the registry, although the entry has never been there to delete. I have uninstalled Samsung driver packages, tried different/older ones. Uninstalled and re-installed Kies multiple times through different procedures. FDR on phone, with and without SD card, etc... among a few other methods that i can't even remember at the moment.

Basically, I have been on this for a week of my spare time trying everything I can find and nothing works. I am very frustrated. I want to root the device. I have rooted many other devices including other Samsung models, however I have never had to deal with MTP.

I don't understand the message on the device for starters; as far as I know Vista does not have a "Service Pack 3". I have Windows Media Player 11 on the PC, however Windows Media Center is what is in Start Menu/Programs. I have a shortcut to WMP that I put there myself. And why does it specify "for Windows XP" when I have a Windows Vista machine?

I hate to be a pain if this has been addressed before, however as I said before, I have tried searching here and couldn't locate a thread with my particular issue and a fix for it. Please excuse me if I have missed something and any pointers in the right direction will be very much appreciated. I also tried to make this as short as possible while providing as much pertinent information as I could.

Thank you for any and all advice.
