SD Card not being recognised

Hi all,

Euro LG H815 running V10b.
I have two good SD cards here - one is FAT32 and has a ton of media on it and one is FAT with just a text file on it to test with. Both show on a PC and both mount fine on a Galaxy S3 and operate well, however neither are showing on my G4. I literally have the SD details greyed out within the storage settings on the phone's menu. No amount of inserting/removing/reinserting and rebooting appears to have any effect.

I'm away on holiday at the moment so not much I can do, but before I try a hard reset and consider sending it back to LG when I return home, is there anything glaringly obvious I'm missing or anything I can try?
I have no apps disabled, not rooted and running all stock.

Thanks.

USB OTG - external devices not recognised

Hi there,

I have a game that I wanted to play with an external controller, I've got a wired XBox 360 controller to hand, so I went down to my local computer shop and managed to get my hands on a usb otg adapter.
I was using a custom rom based on 4.2.2. When I plugged the controller in it gets power and the central light blinks. However, the system gives no message telling me what it is, and the controls do not work for the game.
I tried the USB host controller app and that told me "usb s3c driver not found", or something similar. It also did briefly tell me that the 360 device was connected.
I thought perhaps if I tried a different rom with a different kernel that might kick things into life. So last night I successfully installed the JazzRom from the development page for the Galaxy Note 8.0.
After that, I plugged in a mouse - which, low and behold, it recognized - I saw the cursor moving over the screen and everything! It did seem a bit dodgy though, in that it would say "mouse disconnected" when I hadn't, then I would plug it back in and it would connect again. My USB keyboard worked too.
Then I tried the XBox 360 controller and nothing happened.
I've tried various apps to diagnose the problem - but if the system doesn't pick up the device when you plug it in, it doesn't seem there's much you can do. What's more annoying, now the mouse and keyboard don't work either.
Is there nothing I can reset or alter (I have root access) to help? I've tried the cache in Settings and wiping the Dalvik cache. I have a app called USB/BT Joystick center now, that might help if it could get a signal from the controller, because somebody said it might just be the mapping of the XBox controller that stopped it working.
The only other thing I can think of is maybe a dicey otg cable.
Surely this should work, in theory, though?

Nexus 5 SIM not recognised

People,
I hesitate to ask the question again, but I promise you that I've read everything on the subject that I can find (including many of the 171 pages of the "Nexus 5 Flashable Modems and EFS Backup" thread...) and also on a lot of other sites.
My son's N5 on 5.1.1 ran out of battery a month ago (it worked perfectly for the 15 months that I had used it) and when he recharged it he'd lost mobile data. He had the mobile service triangle in the notification bar, but empty. No service.
I have tried absolutely every suggestion that I've read. Airplane mode on/off. Flashed 3 older radios. Installed older Lollipop & Kitkat 4.4.4 from Google Nexus factory image site. Installed the latest nightly of Cyanogenmod. Installed MPZ79M. Rooted it. Nothing works.
I don't believe it's a hardware problem - when I remove and replace the SIM the notification goes from the square with a diagonal bar across it ("no SIM") to the empty triangle. But as soon as I reboot (not just screen off & waken, but full restart) the triangle is replaced with the "No SIM" square again. The same reaction happens on the initialisation after a factory reset - at the "Register SIM" screen it says "No SIM", but extracting and replacing the SIM starts the "Attempting to connect to service" sceen, though this just does nothing until my patience runs out and I skip it. The SIM itself has 3 scratches along it, so all in all I don't think it's a contact problem, but something in the software. The SIM works fine in the Nexus 4 that I've given him.
EFS - I don't know enough about it still, but the phone displays the correct IMEI, so I'm hoping that this means that the EFS is not corrupted?
I know that this is a well-known problem, but on the off-chance that somebody has read a solution that I haven't found...
Thanks for your patience and any help you can offer.

JIaYu G4 adanced not recognised in Win7 X64

Since I had to reinstall WIn7 my JiaYU G4 advanced is not recognised. It is visible as YunOS ACB interface. I have uninstalled the YunOS, used USBDeview to delete all instances of an Android phone but still get the samen problem. I want to flash a new ROM, (I have 4.2.1 ) Maybe someone knows a ROM that I can install with CWM from the SD card.
Any advice is appreci:)ated :)

Card reader not recognised

Hi and thanks for any help

Moto G 1st gen 4.4.4 UK stock unrooted

Won't see cheapo tiny (so v useful!) card reader plus sd card when my Asus Tab 4.2 and wife's 2nd gen 4.4.4 Moto G will. My Moto WILL see card via otg cable and other reader so I can read/write with that but it's bulky to cart about. Any ideas? Could be very simple!
