ROM with USB debugging already enabled

hi,
I am looking for a ROM I can flash via ODIN and has USB Debugging enabled. It can be any android version.
The reason : my screen is totally broken (both LCD and digitizer). I want to use the phone as a security camera. However, to accomplish this I have to control the phone somehow. There is a way but it requires ADB access which I don't have since USB Debugging was not enabled before the screen broke, and I can't enable it now.
And in case there is such ROM but for CWM only, is it possible to convert it to Odin file?
Thanks a lot.

HELP! Cracked Screen - Big Problem!

Hello!
I looked through the threads and I found a lot of people writing about their destroyed screen and solutions.
Unfortunatelly, I haven't found a similar problem to mine.
So here are the facts:
- Nexus 4 with stock Android 5 Lollipop
- Rooted
- Pattern locked screen
- Touchscreen doesn't work anymore, because screen is cracked
- USB Debugging enabled, but computer is not trusted
- TWRP installed
So I can't just enable adb sideload or something in recovery because it requires my touchscreen and I cant unlock the screen in order to access my files.
I read following thread: http://forum.xda-developers.com/showthread.php?t=2786395 about how to control a device with your PC. However, the tool can't find my Nexus, I think it's because my PC is not a trusted debugging device.
Also I'm afraid the stock kernel doesn't support USB OTG, so this isn't an option either and I can't just sideload another kernel or recovery because TWRP requires touch function.
I hope you can help me asap!

[Q] How to sideload kernel with USB Debugging enabled?

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.

Broken digitizer Nexus 4, trying to control phone from PC

Hi there, the title explains most of it, I'm trying to control the phone with k.janku1's control tool, here : http://forum.xda-developers.com/showthread.php?t=2786395
The phone has USB debugging enabled, is in MTP mode and ADB will find the device fine when I'm in recovery but when I reboot the device ADB won't find the device when it's turned on. I don't know if I'm being stupid or not! I also have all the drivers installed etc

Never used that tool (I did not even heard of it before) but I do rely and suggested to all of my mates to test Chrome extension Vysor, so you could give it a try.

I can't get Vysor to detect the device, I have USB debudding enabled but I'm not able to use the device at all as the digitizer is broken

Ah, I've just read Vysor's troubleshooting guide, it says to be on PTP but I'm on MTP
Is there a known way to change to PTP from MTP with a broken digitizer? I can still see everything on the screen as it's just the digitizer thats broken so I can use recovery via using the volume buttons & power button

There is no problem with MTP, only changing the mode may help to detect some devices. If you are on Windows I strongly suggest you to download latest USB drivers. Eventually check your setup with another android phone.

I do have the latest drivers, the device is detected in recovery mode but not when the phone is on

I'm sorry to know that and I would suggest you to try and contact the developer as I can't help further except for checking with another phone to be sure the computer side is OK.

Broken screen, USB-debugging disabled SM-A500FU (Galaxy A5)

Hello, so I got this phone which has a broken screen, but otherwise it can connect to a pc, so its not completely broken, but before I atempt to replace the screen I would like to test the phone by mirroring it's screen to pc, but unfortunately USB debugging is disabled, since using adb devices lists no devices. Im using chrome and vysor app for chrome, it works on my other phone with debugging enabled.
The A5 supposedly has stock firmware installed, but the user is not sure which version. Is there a possibility of enabling usb debugging via some patch using odin? does chainfire root maybe auto enable debugging?
I'm sorry if a similar thread exists, but I couldn't find it unfortunatley, if it does, please post link, or help otherwise if you know how, thank you.
