bootlooped but dont know how to enable debugging

so this morning i woke up and my nexus 5 was in a bootloop for absolutely no reason, i have done nothing to this phone for a year and half. this happened to me once when i tried to unroot it but my device already had usb debugging on so i could just fix it from there.
so, how do i enable usb debugging on a bootlooped phone? :eek:
thanks in advance
edit: damn wrong thread section, if a mod sees this please move this to the nexus 5 section

[Urgent help]Broke N4 Screen - Need to backup App Data - Rooted - Debugging Enabled

So as the title suggest, my screen is working but not recognizing touch. Basically useless.
Device is rooted, Usb debugging is enabled but RSA Key is not authorised to this pc.
Stock Lollipop with custom kernel.

Problem 1 -
I am already with CWM recovery. From what I have read from cwm recovery I must be able to get access to adb recovery mode so I can backup my app data from system but the device stills shows "Unauthorized" in recovery mode. I dont know why this is happening?

Problem 2 -
I bought the OTG USB Y Cable thinking I might be able to install a differnet kernel that support otg through external power source but then I read that most kernel require to manually enable the option in settings/tweaker app for OTG SUPPORT. I cannot do this becasue as i said my screen is not working.

Please help me out.

After about 2 months with my Urbane I think I'm finally ready to give it the root treatment. I enable USB Debugging in the developer options but never get a pop up on my phone to allow the computer to use debugging. Is there something that I'm missing?

OP2 Not Recognized by PCs with USB Debugging Enabled

I've encountered an odd error, and I'd prefer not to factory reset. Ever since I upgraded to Oxygen OS2.1 (and subsequently installed AK Kernel), nothing happens when I plug my phone into any computer. However as soon as I disable USB Debugging in Dev Settings, the phone is immediately recognized. Has anyone else encountered this, and if so, how did you fix it?

USB debugging mode does not work fully

Hello,

I have Galaxy S5 from Verizon and I am having a trouble making USB debugging working.
It is a little bit interesting that I enabled USB debugging mode and typed "adb devices" on my PC terminal, I see my device listed.
However, I do not see any USB debugging icon on notification bar. Whether I turned on the mode or not, my phone shows no sign at all. This also makes another problem that I am trying to use one of the recovery softwares but even though I enabled my USB debugging, the software does not recognize my phone. I went to my Device manager and I do not have any problem for drivers. I even re-install Samsung USB driver several times, but no help.

I have another Galaxy S4 from Verizon and I have exactly same problem. adb devices work but no notification bar icon. But when I tried out with my Galaxy Nexus from Samsung, I do not have any problem.
Could someone please help me how to resolve this issue?
Thank you very much.
