Root Xoom without USB debugging enabled

So if a Xoom is encrypted and USB debugging disabled, there is no way someone who got physical possession of my locked Xoom could root and 0wn the data? I know on iOS devices, physical possession is enough to Root and SSH into the device.

Neither of those would stop someone from fastboot oem unlocking.

Don't you need to have USB debugging enabled for fastboot to work? Even with bootloader unlocked, all you can do is flash an image which will wipe the device. Right?

Because fastboot is done outside the system, usb debugging wouldn't stop it. Fastboot unlock will wipe the device anyway.

Ok, thanks. So, back to the same point, you cannot read the filesystem of an encrypted Android device if (1) USB debugging is disabled (2) device is locked, even if you have physical possession of the device. This is excluding any microSD card that you use as external storage.

[Q] Touchscreen broken, need to backup files.

Hi, I'm really hoping someone can please help.
I accidentally dropped my 2012 Nexus 7 and now the touchscreen won't work. I am trying to backup the data. The tablet turns on and my PC recognizes it when I plug it in via USB. However because I have a passcode on the lockscreen Windows won't show the files on the tablet until I unlock the screen. This is no doubt a security feature. Is there any way possible to either bypass the lockscreen or access my data another way?
I tried using SkipSoft Android Toolkit but for every option I select it says "Waiting for USB debugging to be enabled".
2012 Nexus 7
Android 4.4.x (Can't remember if it was running 4.4.1 or 4.4.2).
Everything is stock, no root.
Bootloader version: 4.23
The problem is that USB debugging is not enabled on the device, so I cannot use adb. Is there any way around this?
Any help is greatly appreciated.
Thanks

For anyone who might be caught in a similar situation, I was able to enter the pin code via mouse and OTG cable.

[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.

nexus 4 - broken screen and usb debugging turned off

Hi
I have a nexus4 that has a broken screen, it is, it doesnt react to the finger touch, and doesnt have usb debug enabled
What could i do to extract the files from there?
I have seen that connecting a mouse via usb is not an option as this device is not compatible with that, so i think the only option i have is to flash the device to have usb debugging enabled
Is there any other option i can explore?
Thanks

I am sure that you can enter your recovery assuming that your power + vol button is still functioning.
Try to connect your device using Wug Tool and use the tool to back up all the files.
Give it a try and let us know.

Yes, i can get in recovery, but, i assume i would need to unlock the bootloader first, isnt it? If i do it, i will erase all the documents inside

Hi
I have tried getting into recovery, but, as expected, as usb debugging is not enabled, i cant see the device from adb
So, the key question is... how can i enable usb debug in a device with the screen broken and with bootloader locked, without wiping the data?
Thanks

It is possible to turn on usb debugging?
I have clean phone - after factory reset.

unlocked Nexus 7 Me370t wifi issue

I was in the process of rooting my nexus 7 which was working fine before the process started. I got it unlocked and upon setting the tablet up to unlock usb debugging again the tablet will not connect to Wifi in the tablet setup and the skip button is gray. i can see the networks i can click my wifi and type my password but it just goes from (authenticating to saved) it will not connect. the tablet is unlocked i can go into the bootloader and recovery menus. is there a way to flash a custom rom to the tablet since i have access to those menus? my tablet will not show up as connected to my pc so a link to the driver would be appreciated. the one that shows up in a google search didnt help. i am not familiar with adb and was using the nexus 7 toolkit as i have had success with that in the past.

fixed my issue. it was bizarre. I disabled the password on my network and it worked... idk i was entering it correctly but disabling made it connect. my device is now rooted and flashed with a rom.
