Help Nexus 5 in Recovery mode not detected in ADB but another Nexus 5 gets detected

I think I soft bricked my Nexus 5.

I was planning on wiping all data from Nexus 5 and installing Cyanogenmod 12.1 following the normal procedure in the Recovery Mode but the wiping got stuck at Wiping Cache for very long and I ended up rebooting the phone.

My phone has ever since been showing "Unable to mount /cache" error.

To fix everything I thought of installing a Stock ROM image from ADB but my phone does not get detected under the devices list when I run "adb devices"

I have installed the drivers and to test I connected another Nexus 5 which did appear in the list but my phone does not.

Any ideas on how I can proceed to fix this issue.

Any suggestions or help would be really appreciated.

Thanks.
 
Can you connect to the PC in fastboot mode? If so you should be able to flash the factory images via fastboot. I definitely have an easier time getting the PC to communicate via fastboot vs adb.
 
Can you manually update the drivers? If you place the drivers on your desktop and open the device manager on your PC; put the phone into fastboot mode attached via USB and check for the yellow question mark in device manager.

Update the driver, choose "have disk" and browse to the saved driver. See if that will get it to install properly.

Also, what version of windows are you using (if you are) and are you on USB 2.0 or 3.0?

Also are you using the latest adb/fastboot?
 
Yes, I already tried that. I downloaded and drivers and manually installed them for the device. But no use.
I tried this on Windows 8.1 and Windows 7
And the latest version of adb and fastboot.
 
Can you get to the bootloader menu? Try holding the power button for about 10 seconds. As soon as the screen goes black, press and hold the volume down button.

I just tested and this worked even during a boot cycle.

So once there, can you enter your custom recovery? If you can get to recovery, do you have a ROM.zip already on your internal storage? If so, go into the wipe menu and wipe everything except for internal storage. Then flash your rom.

If no rom is saved to the storage, try performing a factory reset from your custom recovery.
 
Looks like the phone was getting disconnected due to bad USB cable. I installed the pre installed drivers and now it shows up int he list. But now when I try to reboot the device in bootloader mode, its shows

error: closed

what does that mean?
