Free Flash Drivers

I am trying to root my lg g4, I began the steps of unlocking the bootloader, downloaded the adb.exe etc, however when I type adb reboot bootloader into the command prompt whilst attempting to fetch my device id, it says device not found.. id be really greatful if somebody could walk me through this process. (thanks in advance)

I have an amba-based actioncam whose name I wont mention because google shouldnt connect it to this page. I found out how to use it as a webcam:

1. Connect to the camera via wifi of your phone.
2. Start the phone app
3. Connect to your camera
4. Once the image shows, quit the app
5. Connect with your computers external wifi adapter(router doesnt work so easily) to the camera
6. Enter rtsp://192.168.42.1/live in splitcam
7. Use the stream - in skype etc.

I want to skip 1. to 4. which are necessary, because the camera does not immediately send the stream only after the app does something to it. The camera support was of no help, they even said that streaming to the computer was impossible, so I downloaded the apk and disassembled it. I see how the app connects in the source code, but I cannot see, which commands it sends beforehand, which I would have to emulate in software on my computer. Can you have a look at the attached source code and tell me?

Man, I installed a rom to my xperia C C205 , but then chose to return to normal.
I returned my phone to normal by wmshua with the official build. (I could not use the xperia application to repair)
But now, the 3G does not work. I turn on mobile data , but the cell acts as if off.
Can you help me solve?

Very annoying when I need to change a permission setting and it nags me about turning off an overlay. Two apps that cause it for me - rotation control and sidebar. Anyone else seeing this sometimes?
