So, my screen cracked out of nowhere and I've got an RMA order from Nexus to replace it. The problem's that I had Paranoid Android and ClockWorkMod flashed to it.
I've managed to reflash the stock Jelly Bean image using Nexus Root Toolkit, however, I'm unable to relock the device and remove the bootloader. Because I've flashed the device USB debug mode is gone and I can't seem to connect using ADB. I've searched on XDA and Google but I've not found any solution that works as I've tried a handful of them. They all seem to require USB debug mode and ADB.
Any advice would be very much appreciated.
Hi all,
I greatly need your help or some advice. I searched for more than 6h yesterday and Im surprised I couldnt find a solution to my problem.
Typical stuff : I broke the screen of my Nexus 4, that is completely stock 5.0.1. The phone is unrooted, bootloader is locked and obviously USB Debugging is disabled.
I need to backup some data from my phone : pictures, notes and if possible my contacts.
When I connect my phone via USB to my PC, I cant browse my files since my screen is locked. My screen is not responding at all, so no way I can unlock it. Only thing I can do is install new applications on my phone, but no way to launch them since I'd need to unlock my screen again.
I have installed adb and fastboot in order to try and use Android Screen Control, but I dont have USB Debugging enabled.
So I read that I could sideload a kernel that has USB Debugging enabled by default.
I got into Recovery Mode, and tried sideloading a zip file containing a Kernel found on the forum, but I always get an error saying the footer is wrong and the signature of the file didnt pass verification. I guess I can only sideload OTA updates ?
I tried fastbooting CWM recovery, that also didnt work.
adb devices command lists my 'recovery' device.
At this stage, all I need is to either be able to unlock my phone so I can access my files via USB (i tried few apps without success), or to enable USB debugging so I can connection using sideload, use Android Screen Control, reset the pattern lock, and backup my phone.
Also, USB OTG isnt enabled by default on Nexus 4, so that's another dead-end
So what are my options ? Where could I find a kernel that has USB Debug enabled, and how can I sideload it considering phone is not rooted, and bootloader is locked (unlocking it and whipping data defies the purpose).
THANK YOU for any advice!
There is nothing you can do with a locked bootloader and no custom recovery. Sorry man, but you're not going to be able to access your data.

I've exactly the same problem, but my bootloader is unlocked and I'm rooted.
I'm also on a Nexus 4 with 5.0.1 and I'm trying to get control over my device from my Windows PC. But I don't know which kernel to use and how (yet) to enable USB debugging.
Help is appreciated.

All you need is a custom recovery to boot into to access your files. If you don't have one, download the latest version of twrp from here. http://techerrata.com/browse/twrp2/mako
Then flash that using fastboot. If you need help let us know.

Hmm, "error: cannot load 'open recovery-twrp-2.3.2.3-mako'.
Sure usb-debugging doesn't have to be enabled?

You have an ancient version of twrp. Install the latest. I'm positive you don't need usb debugging enabled.

Yes, you're so right! I also missed .img in the command
But what kernel would you recommend me to use so I have usb-debugging I can have usb-debugging enabled?
I am in almost completely the same situation! My N4 fell yesterday and shattered at the bottom right hand corner. No the touch screen doesn't work and there are sections of the screen that are black. However, I have...
root
cwm recovery
stock 5.0.1 kernel
windows 7
adb not working
fastboot working
usb debugging disabled
a need for usb debugging to become enabled.
I would like a kernel with usb debugging enabled and instructions on how to install it. Or if you have another fix, instructions on that.
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.
Does your computer recognize the phone in bootloader? If so I would suggest you flash twrp and then try booting to recovery. Then you can check if your computer recognizes it now.

Yes.
Already did that and it did work.
Was able to backup few imp. data.
I just have one more question -
Is there some kernel which support otg in Lollipop without me manually going into settings/tweaker app for kernel and enabling it?
Because I cannot do it manually coz the screen is broken.
I've been googling for a couple hours and every different guide uses different apps, files, bootloaders, kernels... I know for certain that some of these will brick it from past experience. I don't know what else to do. Does installing TWRP enable USB OTG or do I need TrapKernel from some thread I found? Should Odin recognize the phone in "adb download" mode with the Samsung drivers installed on Windows 7? It's not. Is "adb download" the way to install TWRP, the kernel, or some kind of order or combination of one or both? Is TrapKernel or TWRP confirmed working with USB OTG on this model?
I've been googling two hours and haven't gotten anywhere. Most of what I found about enabling USB OTG is written very badly.
Thanks for your help!
Hello,
the touch screen of my A300FU is not working, so i can't access the phone. Unfortunately USB Debugging is not on, so i can't control the phone from a PC.
Can someone help me enabling USB debugging in TWRP? I found several solutions, but none is working, so i need a kind of beginner guide for that.
My second idea was to install a kernel with OTG enabled (Ares, Hades for example). But i'm not able to install the kernel, because i also need to navigate through the recovery.
Can someone help me please?
A300FU, Stock System 6.0.1, Phone Rooted.
