[Q] Network register problem, GSM, 3G connectivity issues... topic

hi to all,
anyone please help me since i got my note 4 n910f i have an issue with it. It doesn't connect to gsm/3g network. Its unlocked/not stolen/not blacklisted etc. The weirdest thing is that after flashing firmware it recognizes sim card and register and just for only one single FIRST time i can even make a call but that's it after ending that call whatever i do it won't register to network or if i manually select search network it keeps searching but won't connect even if it stopped searching after long time it won't show its network name though it show WITHOUT sim card. i have changed sim cards. even used professional help by writing some qcn files etc but after writing those i still got same problem i.e; can call for first time after writing qcn but that will be last.
You people don't think that it calls for first time then won't call until i flash new firmware.
Oh BTW there is another problem whenever i flash lollipop it won't detect in windows but detect every mode on kitkat.

[Q] Change Device Name for Bluetooth Connectivity topic

Hello, I need to change the device name of my Xperia Z3 Compact Tablet in order for certain bluetooth devices to connect, but I can't seem to find this option in the settings. Would anyone know where this option is under the settings menu. As of right now my device name is Xperia Z3 Compact Tablet and it needs to be much shorter. any help would be appreciated thanks.

[Q] Connectivity to PC issue post BOOT-Loop topic

Hello Lovely people of XDA,

It has been a while since I have requested help here due to the huge library of information available but I am unable to solve this one and I think it should be pretty simple.

For completeness, here is the order of events:

ROOTed One and running stock CM11s with no problems since August 2014.
Wanted a smoother system so flashed vanilla Franco Kernel (very nice) yesterday.
Wanted a bit more so after some searching, found the SlimSaber ROM with TyrV74-Linaro Kernel as a suitable choice.

Now, I followed order of install but stupidly, didnt clear the cache or dalvik cache following install.
I got stuck in boot loop so booted to fastboot to open recovery through ADB.

PROBLEM STARTS
My PC didnt recognise my device and this was confirmed through the blank list returned when using "ADB Devices" in the command window.
I updated the drivers through the ADB interface, restarted computer and tried again. Same thing. I then downloaded the drivers from the Google link in one of the forums (http://developer.android.com/sdk/win-usb.html#top), restarted and connected again. I then tried two solutions (although they both do the same thing) and update the drivers through Device Manager and searching for them using the "have disk" option.
This still didnt work.

From what I can tell this is a driver issue but I have installed several times now the most up to date drivers and from what I can tell, the only difference between my screenshots and the help pages/forum posts is that my Device Manager list doesn't recognise the phone as the A0001, just an "Android Device" (pic attached).

I have searched the forums and all roads lead to either re-installing the drivers or changing the driver settings through device manager, both of which I have tried several times but no joy when I use ADB to check for devices.

Any ideas? I will try anything as I now have a beautifully BOOT-Looped OnePlus!

Also, if anyone knows how to boot to recovery from phone off state then that will also help! :)

[Q] Bluetooth keyboard connectivity issues topic

Hi there,

I cannot get my Universal Bluetooth Mobile Keyoard to work with my Sony Xperia Tablet Z. Sometimes it will ask for a code, and before I can enter it an error message pops up saying "cannot communicate with device". Other times I am able to enter the code with no errors, however, key presses are not registered at all on the tablet.

The most confusing part about this problem is that my Microsoft Wedge Mobile Keyboard works perfectly well with my tablet. And what's more, when the Wedge keyboard is connected, the bluetooth module in quick settings displays the Wedge kayboard name. While, when the Universal keyboard is connected, the bluetooth module in the quick settings doesn't seem to pick it up. I have also tried using both keyboards with my Nexus 5 running Android 5.0, and both keyboard work fine. Even more confusion!

It's important to note that while trying to connect either device, I've unpaired the other from the tablet. Basically, only one keyboard is paired with my tablet at any given instance. Therefore, this is not the issue.

I've heard that there was a bug in 4.3 Jellybean which caused some connectivity issues with bluetooth devices. My tablet is running a Cyanogenmod 4.4.4 Kit-Kat ROM, so that issue shouldn't be present here (at least, I think...)

Has anyone encountered this problem before, or have a solution?
Cheers!
