My phone's screen is completely black, but i think the touchscreen works. Can someone give me a screenshot of the pop-up that appears when you connect Android KK 4.4.4 to PC ? Thanks.
Or if someone know another way to recover data? I don't think I have USB debugging ON.. How do I check, adb devices?
Update: no devices in adb.
Device?

Whenever I connect my phone through usb to my pc neither my phone nor the computer recognizes it as connected. Which is rather displeasing in case i need to back anything up to my pc and/or need to get though adb to update recoveries or whatnot. is there anything i can try to fix this...or could this be a bug within the rom?
Thanks!
Hi Guys,
I've had a few problems with my N5 recently...
If I plug my N5 into my PC via the stock USB cable and boot into the Bootloader (PWR+VOLDN) then it will allow me to flash the original N5 firmware, located here: https://developers.google.com/android/nexus/images, this would indicate to me that there is no issue with the actual devices ability to transfer files via USB connection... Right?
No!
For some strange reason my phone will allow me to push a full factory image to it and will also process any Fastboot commands that are sent to it but as soon as you boot into something like TWRP and try to control the phone's ADB functionality it will not find the device at all! The new MTP option in TWRP 2.8 will allow my computer to see my phone's MTP connection for about 1 second and then will immediately disconnect, the same happens when trying to connect to MTP from within Android too.
USB debugging doesn't show that it is connected when my phone is plugged into my PC and Windows makes the 'device connected' sound and then straight after makes the 'device disconnected' sound...
Any ideas? I am certain that this is an issue with my handset's hardware or software rather than any of the computers or cables... I have tried 3 different cables (including the stock cable) and also three different computers (Windows 8.1 @ Work, Mac OS X @ Work and my own personal PC running Windows 8.1 & Ubuntu @ Home)... All OSs and all computers run into exactly the same issue, device connects briefly and then disconnects.
I have troubleshooted issues relating to the driver. This is not the issue... Device Manager cannot even see the hardware after the disconnect.
Thanks for any help in advance,
Lewis
Also:
-Android does not detect that the USB is charging the device unless the device is booted with the cable attached (if it's not attached before the 'Google' screen then it can't see the USB input at all, within android or TWRP, of course...).
Having the exact same problem. Did you find a solution?

It's most likely a driver issue.

Not a driver issue.
3 different Nexus 5s, 5 different workstations. Other two Nexi are fine on all 5 PC's.
1 PC used for ADB forensics, 2 used for ADB development work, one known working for ROM'ing / rooting.
Phone has been factory reset, factory ROM'd from Fastboot. Connects fine on Fastboot. Will not connect on ADB / MTP.
On a fresh PC / phone reboot, the PC will detect the phone for just a second and then it will not reconnect until process is completed.

Hello,
my problem is that I´ve got a Nexus 4 Smartfon and the sceen is broken, so I´m not able to enter my pattern. because of this I also am not able to save my data because without entering the pattern, my computer doesn´t alowe the access to the memory.
I tried two different ways to get access to memory by using ADB:
1) I tried to delet the pattern (gesture.key) file.
I tride this first with my rooted Samsung Galaxy S3 mini and it worked perfectly. it also has USB debugging turnt on.
But my Nexus 4 hasn´t USB debugging turn on. I tried in on my S3 mini with and without and without USB debbuging it also didn´t work out.
Also my Nexus 4 isn´t even recognized as an ADB device, only in sideload mode or fastboot mode. I also think this is because of the not turnt on USB debbuging.
2)i tried to turn on the USB debbuging, so my device will be detected as an ADB device, or i can you a programm to mirror my smartphone on my computer and insert the pattern via computer.
I´ve found a pretty good tutorial on the internet but this didn´t work out. Also on my S3 mini it did´t work
So my last idea is, to us a little programm/application which i can transfer via sideload to my device and which will delete the pattern on the phone. my problem is that I´m not a programmer so I can´t do this myself.
so i would like to ask what do you think about my idea, if you could help me or do you have any other suggestions what i can do to save my data.
i´m ver thankful for any help :good:

Hi together,
my touchscreen&display are broken. Now i wanted to clone my screen to my laptop by ApowerMirror. The app can install the Phone-Client via ADB. USB-Debugging was enabled on my Mate 7, but my Laptop isnt Authorized.
HiSuite also tells me, that i have to press the authorize-button on the phone.
CWM Recovery is already installed, but i dont want to boot in the recovery, because there is no way back in the ROM until i have no screen and Touch(PhoneLock)
I wanted to try to press the button with a connected mouse, but when i unplug my Notebook the AuthorizePopUp will disappear.
BTW: I also tried to connect the Mate7 with a MHL-Cable with the TV...No funktion. Do your Phones support MHL?
just connect an otg mouse and keyboard... you know, get root by cwm, then use wifi control it instead of adb
