[Q] Using Nexus Root Toolkit without USB Debugging enabled

I have a 2013 Nexus 7 wifi tablet, bootloader locked, with USB debugging disabled. It decided mid-activity that all it would like to do in life is display the "Google" image on the boot up screen.
I can access the bootloader so I tried doing the standard wipe in recovery mode but that did not work.
Investigated Wugfresh's Nexus Root Toolkit. Drivers (Windows 7) are installed but under Step 4 of the Full Driver Configuration guide it is unable to find the device as an ADB device, even though the device does show up on my Device Manager (but only as bootloader interface, not ADB). Tried to use the unlock feature anyway but on the tablet it just gets stuck on the "unlock bootloader" screen after trying to run the unlock tool (choosing "yes" by pressing the up volume button to scroll to the yes option, followed by the power button to select it).
My questions based on this are simple:
1) Can I unlock this device without having USB debugging enabled? If so, how?
2) Can I restore to factory stock settings without having USB debugging enabled (and not using recovery mode on the device itself, as that does not work)? If so, how?
All of the tools I have seen thus far require that USB debugging be enabled on the device. Since I can't actually boot up the device, there is no way to make this happen. I don't really care about any of the data on the device, I just want it to function again to avoid buying a new one.

Stop using a toolkit. Your device will never be recognized by adb when booted into the bootloader.
Unlocking the bootloader is simple if you have the Windows drivers set up correctly. Open command prompt with admin privileges, type 'fastboot oem unlock' and done. This is why I hate toolkits.

I believe this also requires that USB Debugging be enabled. I would paste links but the forum prevents me from doing so since I just signed up.
If I am incorrect in thinking that USB Debugging must be enabled for this to work, then please let me know. All I really need is clear instructions on how to hard reset the device without USB debugging enabled. Unlocking just seems to be a prerequisite for that in most of the tutorials I have found so far.

You can flash the device back to stock with wugs without adb. There should be an option you pick under the factory restore button that says "soft bricked" which tells wugs that it needs to go straight fastboot mode instead of trying to restart the tablet with adb.

Thanks for your reply. I have tried this option without the ADB (but with my computer recognizing the device). Since it did not work I expect the device is well and truly screwed (the recovery mode factory reset also does not work on the tablet itself).

Couple of things:
1. You may also have a driver issue, I was playing with this the other day on both my Nexus 5 and Nexus 7. My nexus 5 worked fine, but later that day when i tried my nexus 7 I had troubles with my PC recognizing the N7 in fastboot mode. It would be fine in ADB and would reboot, but then the computer would freak out when it saw the fastboot device. Sometimes it would kinda work, sometimes the N7 would freeze on the bootloader screen or fail to flash during the process. It even locked my PC at one point. I completely uninstalled(per the Step 1 instructions in Wug's) all Android associated drivers(Samsung, LG, Asus, whatever. Kill them all) on the PC and reinstalled and it solved the issues. It sounds like maybe your PC is failing to flash properly like mine was.
2. Not sure if you tried this yet but; go to Options Menu>Flash Stock Tab>Check "Enable 'Force Flash Mode' . . . " Then try to flash stock + unroot again with the soft-bricked option selected. This basically makes Wug's ignore the check process at the beginning of the flash. I had to do this for both my N5 and N7.
Keep in mind, you will lose EVERYTHING on your N7 if you unroot and flash, including your internal storage.

Yeah, it does not seem to want to do the unroot + flash even with the override of checks. It seems unlocking is really a prerequisite for that tool (according to the text that appears as it proceeds), and unlocking appears to require the USB debugging. If it really can be unlocked without that, then it is not cooperating and just getting stuck on the unlocking screen. I expect it is now a very expensive paperweight.
All of this nonsense just over a year since I bought it, of course.

Try it with another computer, another USB cable...

I'm in the same boat, can't get it to unlock so it's essentially dead now
I've tried original and a G3 usb cord and nothing, front and rear USB ports, just will not unlock, almost to the point of sending it on and paying to get it fixed if possible , will try another computer first

Can you boot manually into fasboot mode and do flashing full stock firmware for ur device..
Bcoz I thinks you don't need usb debugging when on fastboot mode..
if you want to use toolkit, you must setup all driver for ur device first using the toolkit.. but you must do it when ur device is full "working", not when It's just stuck on google image... that's ur main problem now ...
you should try install the driver again on new "fresh" pc ....
Good luck bro... :fingers-crossed:

Did you try to manually unlock it? Boot to the boot loader screen(down volume+power) and the fastboot unlock it using the cmd in windows?

I can boot into fastboot mode but when I then switch to recovery mode manually to reset it does not go to the recovery mode screen (it did at first, but now just gets stuck on the sick robot screen, then on the "Google" loading screen).
I can try the drivers again on another PC, but I have a feeling that won't fix anything.

I looked into this a week or so ago and I think I determined that it would also require the USB debugging to be on (at least from the tutorials). Do you have any recommendations of tutorials on this process? Screwing around with this stuff is not really my bag.

Ok.., Your have no choice by now, you'll need to find a working driver for your PC to get recognize your tablet when on fastboot mode..
I've got this issues before when I want to update my tab using toolkit...
My PC can recognized my tab as adb devices, but when it's reboot to check fastboot status it fail to detect my device is on fastboot mode..
But maybe I'm so lucky that day, Moboginie notification has pop-up and it's has searching and found the driver and fix it itself ...
Then i try again and this time it's has no problem at all till now... I still can access my storage using Moboginie but until now window explorer still fail to recognized my N7...
It's so weird isn't it ...

Try Moborobo

After the recovery screen with "sick" Andy, did it automatically begin to reboot? If not, you know that it's very tricky with the power+vol up button (sometimes I think it's power+both volume buttons that works) to access that screen in recovery (the one past sick Andy). Sometimes I've tried five or six times. I have twrp so I can't check it out right now.
As far as adb/fastboot drivers set up to run any commands, I thought they were required. I'm not certain about USB debugging. It seems you've tried with your device in fastboot and running Cmd (fastboot oem unlock) from your fast boot directory. Do you get a device code when you enter [fastboot devices] while in that directory? If not, your N7 will not accept fastboot commands.

Stuck on TWRP Recovery mode (LG G3 d855)

So after accidently wiping everything I had on both SD and Internal memory trying to make a custom rom work, I was stuck with a phone that only has TWRP on it, basically. Now after I've been through this guide TO THE LETTER: http://www.droidviews.com/install-stock-android-marshmallow-lg-g3-d855-using-twrp-recovery/ I can see it installed an OS but I cant seem to get my phone to load it! SO then I tried entering recovery mode and getting back to default, it didn't change anything, so I tried installing Zoe rom (https://forum.xda-developers.com/lg-g3/development/zoe-rom-v1-0-mm-6-0-stock-v30a-d855-t3402087) and It STILL ONLY LOADS TWRP even though the installation seemed to be successful!
So what do I need to do? Just flat out delete TWRP? or what? Pleas advise as I'm desperate. If needs be, redirect me to how to just completely reinstall everything from scratch to 6.0 or 7.0 (preferably). I was on 4.x.x for ages and I just wanted to update, instead destroyed my phone. Sigh.
UPDATE: Another thing I've tried is to flash it with KDZ file from the PC. I can see the phone, I can transfer files to it, but windows DOES NOT recognize in the device manage so when I tried to use the flash tool, after clicking "Start" it pops a new window which gets to 60% and then stops saying the phone is not connected to the pc.

I just got over something like this this morning. First, you need to ensure you have the LG Universal drivers installed for your phone. Get them here.
Next, reboot your machine.
After this, I made sure the PC recognized all 3 modes of my phone, TWRP mode (boot to TWRP, connect), Download Mode (boot to download mode with cable) and, at least in my case, the flashing lights mode (shows up as QHUD Bulk or something).
After that, I ran the KDZ restore program successfully.
Good luck and let me know how it goes.

Bricked my mi max after flashing twrp, is it dm verity?

I installed twrp and bricked my mi max. I slid the slider to allow modification.
I get stuck at the mi logo on booting. It's not moving.
I can't even power off the phone. The stuck mi logo is always there.
I managed to roll back to the stock recovery.
Booting into this recovery is still possible but I don't know what to do from there since it cannot see any Tom to flash.
Booting into fast boot is possible, but the phone is not detectable on PC.it doesn't show up in device manager. It was previously detectable, before I flashed twrp through fast boot .
Is there any way to unbrick the phone without losing my internal sd card media?

No way to unbrick without losing media
Your phone is encrypted
Wipe data from twrp and flash any rom of your desire from ex-sdcard
This should unbrick the phone

I assume your device is unlocked, there's no way to unbrick you device without loosing data.
Try this step
1. Remove your battery / unplug battery & replug it again.
2. If can enter fastboot mode, and type this command on adb
Fastboot device (make sure your device is detected)
Fastboot oem edl ( your device will be blank & become qualcom)
3. If step 3 doesnt work, before connecting to PC. Connect edl pin on motherboard then connect your to PC (detect as qualcom)
4. Run Mi flash & flash your miui ROM, wait untill finish.
5. Try turn on your device.
Hope that help

Stuck in Bootloop

Hello!
Unfortunately my 9 SE (6GB RAM, 64GB ROM, bought from e-tec.at) got stuck in the boot loop yesterday afternoon.
About the phone: European version, has the latest updates on it, no custom Rom, USB debugging mode is unfortunately not set, no Mi backup, was not registered in the MI account).
The storage space was already quite full. The "MI deep cleaner" app was running and got stuck, a window is constantly popped up. Honestly, I can't say if I clicked and just deleted an app by accident. I heard that it can also be a problem if you simply delete certain apps. So I wanted to restart the phone and it has been in the boot loop ever since. Actually I don't no the real reason it was lagging.
I get into Recovery Mode 3.0 and Fastboot. But I really want to have the photos on my cell phone again, so I dont want to swipe all data. The cell phone is recognized via the PC, but cannot access via the Xiaomi PC Suite (which should be out of date?).
I still have a guarantee for my cell phone. What if I would send it to Xiaomi support, would theyy try to save the data or simply reset everything to factory settings? Who has an idea how I can solve the boot loop problem?
Should I take the cell phone off the power until the battery runs out? It is reboots all the time.
best regards, thank you for your help in advance!!

@Chewei8152: try to get /sdcard of the phone visible in file explorer of pc during recovery or fastboot mode. Then copy your files to pc. Sorry, but there's only a very little chance. (Assuming stock recovery and USB access off.)
Xiaomi repair service will advice a factory reset first and, if they accept your delivery, surely not save any data before.

Thank you for your reply! How do I manage to get the sccard visible?
Do you think that is possible to flash the phone from EDL mode without clear the data (from someone who can do this for me)?
Cheers and many thanks!

Stuck on redmi note 8T logo (How to recover personal files in internal storage? - Bootloader closed)

After turning off phone with battery 1%, it was charged normally.
Later at turning phone on it got stuck on logo and didnt boot.
Redmi note 8T (two years old, worked always very well) , factory miui 10, Android 9... So bootloader closed and debugging USB disabled.
Recovery mode: pressing reboot to system doesnt work, stuck again on logo.
Fastboot works only, after 10-15 minutes on this mode phone turns automatically off.
Dont wanna select wipe on recovery, as I wanna recover personal files on internal phone storage.
Phone serial number is recognized by Linux PC, and possible to boot phone vía fastboot and terminal commands, but does the same behaviour.
The question:
IS IT POSSIBLE TO RECOVER PERSONAL DATA (without wiping all)?
If Yes... What way? And what way on Linux PC?

a phone with a locked bootloader is a wall
and even if you manage to recover your files they will be encrypted

You mean that even though internal memory were extracted and analyzed... data could not be read for being Android 9 encrypted?
So it's not worth to take it to service center...

i don't think so, they will try reinstalling miui which you can do your self ...

With the help of XiaoMiTool V2 (unofficial) compatible with Linux I fixed the brick. It wiped all the internal memory but the flash of stock willow fixed the soft brick.
There's a small mistake on the list of phones of the tool... You must choose Redmi 8T. And the phone was reset as new from factory. Miui 11 now.
This tool was developed by an Italian and allows to flash stock rom with a lock bootloader and usb debugging disabled.
In case it may help someone with same issue. Just need a computer and connect to phone via usb cable on fastboot mode. Of course ADB & Fastboot tools must be installed on pc.

did you recover the files? or did they get deleted?
