[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.

[Q] No Download mode, no fastboot mode, no hard reset mode

Dear all,
Thanks for reading this post first. I have a G3 D855 with a unknown ROM inside (as i bought it from others, i don't know what the ROM is, but it is obviously a custom ROM). I try to flash a stock ROM and search the method from the net, but no method i can use for the following reasons:
1. i can't go into download mode (tried turn off phone, hold volume+ and plug in cable method)
2. i can't go into recovery mode with any key combination (used the method online, the screen will light up but LG logo won't show, there light off, keep looping like this)
3. i can't hard reset with any key combination
4. as you can see above, i can't get into fastboot mode with any key combination (but i do can use program in Win7 to call the phone into fastboot mode)
5. When i connect the phone (turned on) with Windows 7, it can recognised as LG G3, and i can explore the internal storage. But if i try to connect it for the Download Mode, then it can't be recognised, just "dang dang" sound from the computer. (i have installed the latest LG drivers). My phone can't be recognised in Ubuntu.
So, i try to figure out what has happened to my phone, and after searching for few days, i believe that i may flash sbl1.img, aboot.img, rpm.img, tz.img to get back the above modes for my phone (see http://forum.xda-developers.com/showthread.php?t=2582142). I would like to know if my thought is correct at this point.
If yes, can i just make my phone into fastboot mode with the help of the Windows Program to flash back those img, or can i use Flashify to flash those image?
Thanks for all your help.

[Q] Gnex Brick Mount Fastbood Write Fail help :'(

Hi everybody,
ok I will try to make this short
I have an experienced user level ROM, recovery, boot, ..
My phone is BRICKED! Is it?
AT THE MOMENT:
- I get into fastboot mode
- I get into odin downloading mode
- I can't start in recovery mode
- I can't start bootloader mode
- I have a connection with a laptop (win XP, as win8.1 didnt work for me)
- The computer can communicate with the phone in fastboot mode
- The computer cant communicate with the phone in Odin mode (at the moment Odin PC SoftWare doesn't recognize the phone)
- I am sure the drivers are installed correctly now. Thanks to the guide with fully stripped drivers.
- Using different, multiple different, no thousand different methods I tried flashing the stock OS (Yakju 4.3)
- I like SkipSoft Android ToolKit (Although I used fastboot and adb commands, I find the toolkit to do the same thing..)
- I always get an Error, when the process of flashing starts.
> PC says : Error
> Phone (in fastboot mode) says: FAILWrite Fail
INTERESTING:
- While I still was able to get into Recovery, the phone couldnt mount the sdcard (=> the internal drive)
- Some of the methods I use make the phone CRASH
> means the screen stops at its position and slowly turns completely purple
- The phone power button doesnt start the phone, to get the phone doing something at all I have to trick it:
..> I plug it into the wall charger
..> I take the battery out
..> I put the battery back in
..> I wait
..> I can get into 3 routines:
^Normal starting routine (of course stuck at google start up, since no Rom is installed)
^fastboot mode (VOL + & - & Power)
^odin mode (VOL - & Power)
..> Then I can just plug the USB cable into the PC
- 2 days ago I had (every single version) of Odin PC Software recognizing the phone (phone was in Odin mode), but it also failed after trying the recommended and unrecommended settings. Ended with an error message.
HOW:
I left my phone overnight in the car (Temp: -2 deg C), while Im sure spotify and maybe other consuming apps were playing.
Next day, my phone battery was empty and I couldnt start my normal ROM. (I had Slim Rom installed)
It was stuck at the "Google" start up display.
First intentions showed that it might be more than just the Software :/
Many days and so many hours of work, research and reading in forums, I decided to take a shot and ask here.
I appreciate everything xda-members have done for me already. Though I never needed to register for my earlier questions.
Phone data:
Product Name - tuna
Variant - maguro 16gb
HW version - 9
Bootloader Version - primemd04
baseband version -
carrier info - none
serial number - -a3c208 ***
signing - production
lock state- unlocked

BUMP!!! I have absolutely the same problem!! I can access everything, i enter the recovery trying to WIPE every single thing data,system,cache,storage etc.. but it seems it doesnt work. The information stays. I tried to "softbrick unroot & stock" with a nexus kit, everything seems ok, but after it finishes installing, it boots up on GOOGLE and after 10-15 min it starts to BOOT MY OLD CUSTOM ROM THAT I HAD BEFORE, after another 15-20 min it finally boots up and the system is EXTREMELY choppy and unresponsive and after a few minutes it restarts itself. I tried ODIN and I faced the same problem, it goes well to ~45% and then it freezes, and after a short delay odin gives FAILED. I tried several more things that i found on the internet and xda but nothing helps. Probably a corrupted partition or something. THE DAMN STORAGE DOESNT WANT TO DELETE ITSELF FFS!! PLEASE IF YOU KNOW ANY FIX/ALREADY FIXED YOURS PLEASE HELP!!! I need my phone!

can you give us more information about the error message?

Similar, only difference is with fastboot i can successfully flash system.img but nothing happens. With odin it fails at around 45% and then freezes. Only difference is that i cannot boot to old stock and i dont have this pulpish problem. I simply reboot on my old custom ROM configuration with all my last known icons widgets.. but the phone is choppy and unresponsive as hell.

I only get an error without any further message after flashing any of the images...
Any idea anyone? Isn't it some hardware issue?

Noo man i dont think its hardware problem, for me it all happened when my phone suddenly restarted itself and after that it bootloops forever and i have those problems

Anyone?

does erase work?

yes

can you get into recovery?

ka

how do you know that erase works, I mean that what you erased has really been erased?

One of the erase command in the toolkit was succesful, I guess. But I will recheck every error or successful message later tonight.

still NOT working
2 months have passed and I was too busy with other things.
now back to it. the problem hasnt changed.
i try fastboot flash command:
[fastboot flash bootloader x.img]
- in Computer Terminal: 'FAILED(remote:Write Fail) '
- on phone: ' FASTBOOT STATUS - FAILWriteFail '
any idea, please?

Bricked Swift

Hello Everyone!
I recently tried to root my wileyfox swift but failed miserably. I did the following when fastbooting the recovery image -> fastboot flash system ****.img.
However, i realized my mistake too late, and now my phone is all messed up!
The phone doesnt show anything when i try to start it and i cant access fastboot again, to undo my mistake. My device manager recognizes my phone when its plugged in to my computer but i cant access any files.
Am i screwed or is there any solution to this?
Thanks in advance!!

Try to access the bootloader with the hardware button combo first (volume down + power / volume up + power). If you get into recovery, you will be able to get to the bootloader with adb or a menu entry. Depends on what recovery you have installed for the latter.
In case you have no access to the bootloader (proper soft brick), go for the QFIL method. Avoid using it unless there is no other option.
Here is the thread:

Cant access bootloader.
However, tried your second option and it went well until i got "SaharaDownload fail" at the last step, and now my computer doesnt recognize the phone in device manager. It does not show anywhere that my phone is connected.

Does the phone give any indication of being connected? Notification light, starting the display, etc?
If yes, make sure the phone is in the correct mode and check the drivers - some of the other forum members mentioned this and the gymnastics around the battery. This would be on my to-do list. The device might come up on the device manager as different one, so monitor the manager for any changes once you connect the device.
If you happen to have Windows 7 device laying at you house, you can try with it (if only not to worry about compatibility and sporadic Win10 behaviour).
It will be a good idea to check the turkish website for General Mobile 4G (one of the Android one derivatives of the hardware) where some people have faced similar problems using the same tool.

How to remove BootLoader unlocked notification from boot screen

Hey all. I'm in a bit of a pickle. My Tmobile LG g4 has stopped fast charging. When I plug in any cable, I do NOT get the USB notification which allows me to connect to my PC. Enabling the MTP option in the Dev options still does not allow the device to be connected to the PC to flash back to stock for warranty support.
Is there any way for me to save something to the SD card to reset back to stock? Do I have to connect it back to stock or at least relock the boot loader?
I've tried multiple PC's and multiple cables with no success to get the device connected. When connecting to a PC, I get. The device has malfuntioned on my machine.

does it go into download mode.? phone off vol up key and connect usb.?
if you want to remove unlocked bootloader follow this comands
UPDATE:
I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in
Quote:
adb devicecs
- you should see the phone listed as one of the devices in the command line window
Quote:
adb reboot bootloader
- phone should reboot and you shouold see 3 lines of text on top
Quote:
fastboot oem lock
- nothing will happen on the phone, but on in the commandline it should say that it is done
Quote:
fastboot reboot
Phone reboots and the boot screen does not show the unlocked bootloader message anymore

Unfortunately, the computer will NOT detect the phone. No computer will. Using a USB cable that came with it , no luck either. Any ideas?

so basically theres no comunication with phone. not really. unless you go and exhcnage it to tmobile, so you cant remove bootloader unlocked message either. if you lucky and tmobile doesnt check for it then you may be able to get it exchanged. as it not recognized in any computer ill say its hardware problem. good luck.
