SOLVED
See my most recent post in this thread
______________________________________________________________________________________
Firstly, I've spent the last three days scouring XDA and some other forums searching for solutions and trying various options.
The screen on my N4 has cracked and I've lost the use of the bottom half of the touchscreen. This means that I can't unlock my phone.
The phone is insured and will be repaired, but there are photos of my son's first birthday on the internal memory that I don't want to lose. I'm concerned that the phone will be factory reset during a repair or I'll receive a replacement. I'm trying to access the internal memory remotely to backup these files before I send the phone off. The problem is that I hadn't enabled USB debugging before the accident. The phone is completely stock including the bootloader.
So I can access via fastboot but not via adb.
Q1: Can I pull file from the internal memory via fastboot
Q2: Can I enable usb debugging via fastboot
Q3: The phone is set to display as an MTP device in windows but as I can't unlock the screen, none of the files are showing. Is there anyway around this?
Q4: Purely via fastboot, can I unlock the bootloader, install CWM so to use ADB within it and then return to a stock bootloader?
I think they're my options. Any answers to the above or alternatives would be appreciated.
All of the other threads regarding this, the users seem to either already have CWM installed or they're looking to perform a factory reset. I did consider resetting the device via the bootloader in order to bypass the screenlock but I understand that on the N4 this wipes the internal memory as well.
Unlocking the device isn't needed to pull the files from it, just plug it in and get what you need from the internal memory

On mine if I plug it in it appears as an MTP device but with no files. I then have to unlock the screen and select USB something-or-other from the notificationss bar, then the files appear in windows.
Strange, mine never needs to be unlocked...I'm using Windows 8 Pro btw but it also works fine in work on Vista Business
Only other thing I can think of is the fact I'm unlocked and running a custom ROM, I've never used my N4 stock. It was on CM within 30 mins of receiving the unit!
So over the last week I've managed to solve my problem. I've seen several other people asking for help with no luck so I'm posting this here in the hope that the search function will bring it up.
Firstly, my phone was completely stock running 4.2.2, unrooted, with the locked stock bootloader. USB Debugging WAS NOT enabled. I had pattern lock enabled when I dropped the phone. The screen cracked and the bottom half of the touchscreen was unresponsive.
The phone was insured, but I wanted to backup photos from the device before sending it off for repair/replacement.
HOW I FIXED IT.
Please note, you need at least some part of the screen to be working, specifically, some part of the screen where the pattern lock is.
You only need two pieces of software. The Android SDK and the Nexus 4 Toolkit http://forum.xda-developers.com/showthread.php?t=1995688
If you are running 4.2.2 you will need to update the toolkit. I also had the standard issues of installing the USB drivers for the N4. You need to get to a point where is shows up as an ADB device in Windows Device Manager.
As I didn't have USB debuggin enabled I couldn't connect tothe phone via ADB, but if you put it into recovery mode you can use Fastboot. Hold down the power key to turn the device off and turn it on while holding down Vol Down to load up recovery mode.
If you then start the N4 Toolkit, you should see the device listed as a fast boot device.
From within the toolkit unlock your bootloader.
Flash a temporary bootlader, (option 10) as the touchscreeen was broken it has to be CWM.
Once in CWM you can start to use ADB. Open up a DOS command prompt in Windows, go to your SDK/platform tools folder/ to access ADB.exe and you can use the pull command to copy folders to your PC. At this point, instead you can use applications like ADBexplorer or DroidExplorer to do the same thing through a nicer GUI.
If you'd like to still be able to use your phone, although without the touchscreen, you can load an unstable image to get into android and then use ADB to start changing system settings.
Firstly, before exiting CWM, clear the cache. Without doing this the phone jsut hung on the Nexus symbol while loading the image.
in the toolkit go to root/unroot options and select load unstable image(option 4 and then 6). This will fire you up into Android and it should be set up as you left it.
I wanted to enable bluetooth so to use a keyboard (I didn't have a mouse but this is a better option) from the DOS window type the following command
am start -a android.bluetooth.adapter.action.REQUEST_ENABLE
You should eventually get a pop-up on your screen saying that a request has been made to enable bluetooth. Hopefully your screen is working enough to select enable.
Then I use the workaround to disable the sceenlock, found here -> (http://www.addictivetips.com/androi...e-pattern-unlock-on-android-via-adb-commands/) I found method 2 worked for me. I imagine this will be stopped in a future update.
Method 1
adb shell
cd /data/data/com.android.providers.settings/databases
sqlite3 settings.db
update system set value=0 where name='lock_pattern_autolock';
update system set value=0 where name='lockscreen.lockedoutpermanently';
.quit
Method 2
adb shell rm /data/system/gesture.key
If either of these methods are successful you will be able to unlock the phone with an pattern, hence why you need to be able to touch some part of it.
From then, my bluetooth keyboard was already mated to my phone to I was able the navigate the menus to turn on USB Debugging, turn-off the screen lock and a few other bits and pieces I needed to do.
I then restarted (I was still working within the unstable image) and on reboot, all my changes had al been applied. No screen lock, bluetooth enabled and USB Debugging enabled.
Hopefully this will be of help to those in a similar position. Thanks has to go to the toolkit though which provides all the necessary access to carry this out.
I should probably add, you can use the toolkit to relock the bootlader if you're concerned about that and if you can't click the screen to enable bluetooth or mate a keyboard or mouse, once you have USB Debugging enabled you can use software like Screencast to control you phone's screen from a PC.
So typically, just as I fill my claim to repair my nexus my wife drops her, smashing the screen even more than I did so she has absolutely no use of her screen. I went through the process again and though I'd post it in a more simple fashion.
1. Reset Nexus into recovery mode (power & volume down)
2. Connect to PC via USB. Install the USB driver from the SDK so that it appears as an ADB device
3. Fire up the updated toolkit. You should see the nexus as a fast boot device
4. Unlock bootloader
5. Using option 10 on the toolkit load up CWM on the phone. This gives you ADB access so can you pull files off the device via ADB although I could access the SD card through programs like Droid explorer.
6. If you want to carry on further and get into Android properly, you'll need to wipe the cache from within CWM
7. Reboot and hold down the volume key to get back into recovery
8. In the toolkit select root options (option 4) and load temporary image (6) If it hangs on the google or nexus logo you've not wiped the cache.
9. With this second phone I couldn't access it through droid explorer as it was popping up as an MTP device but I could pull the files via command prompt or through the toolkit
10. If you have any use of the touchscreen at all you can run the following command which will then mean that any touch will unlock the device
adb shell rm /data/system/gesture.key11. You can activate bluetooth via adb if you have a mouse or keyboard available but you will need to be able to press okay on the screen
12. Any changes you make in the unstable android image such as lockscreen, bluetooth, enabling debugging, etc will remain in place when you restart the device.
13. You can relock the bootloader if you wish via the toolkit. You just need to be in recovery mode first.
Hope this simplifies the process
Does unlocking bootloader via toolkit not wipe everything? How are you unlocking bootloader and still able to pull data off?
EDIT: it appears fastboot oem unlock on the Nexus 4 *does not* wipe data!

Please HELP, i can get to step 5...but then, when I try to use ADB via cmd (ie. adb shell), it says "error: device offline". what can it be? I don't know if this is a driver related issue (i've tried the toolkit drivers and the SDK drivers)...i'm desperated, I can't access the phone!!
Thanks in advance
not working for me
i'm in same boat with cracked screen. i can get CWM installed but i cant enabled usb debugging without touching the screen so i cant get adb working. how did you turn on usb debugging without the screen
Thanks for the guide.
Im curious on why youd want to boot an unstable(temporary) image after pulling the files using ADB in CWM recovery. Why not just wipe cache and reboot normally into Android ?
usb debugging without screen?

Can someone please walk me through how to do this? My screen is completely broken, but I can still turn on/off, I have reason to believe debugging is off because when I connect the phone (a Samsung galaxy sII skyrocket) to my Toshiba laptop via a micro USB, it makes a sound to signal that it's connected. Drives E and F then open up (but are empty) and then disappear. I have no idea what's going on but I absolutely cannot lose all of the data on this phone. Pictures and videos from my old blackberry Torch are on here too, making up about 4 years of my daughter's life that I would lose if I cannot retrieve. Also, I am not super -tech savvy, so if someone could help me I would be forever grateful.
Please!!

almost the same issue
I have an Asus memo pad 10 (smart) some of the core apps have been corrupted, (keyboard, UI, launcher etc all the essential stuff) I've been trying to reinstall my UI and launcher from my computer when i found out that USB debugging was disabled. the tablet is basically unusable, i have no way of enabling from the tablet itself. is there a piece of script or something i could run from my PC to enable it?
any help would be greatly appreciated :crying:

My screen became unresponsive a while back. I ended up getting and OTG cable and plugging in a mouse. This allowed me to do everything as if the touchscreen was working. There's also an app called MyMobiler that let me plug in my device over USB and control my screen from my PC. Those two helped me enable USB Debugging, flash a custom ROM, root the phone, backup everything I needed, then restore the phone to stock. I hope this helps.
*Sorry for bumping such an old post*
Thanks for the really useful guide!
Could you or someone just confirm to me that unlocking the bootloader does not factory reset? The reason I'm doing this process is to access my personal data so it's important that I can keep it all.
I ask because at the unlock bootloader stage it implicitly warns me that there'll be a factory reset.
Thanks again!

In that case, I am confused as to how OP managed to unlock his bootloader. He actually states that the purpose of this was to retrieve data, like me.
Also, in a previous comment in this thread by jw95275, they claim that "it appears fastboot oem unlock on the Nexus 4 *does not* wipe data".
I am concerned about the conflicting answers so far, so will hold off for an explanation before I do anything. Thanks for the response!

You should just be able to "fastboot boot recovery.img" and boot CWM and then use ADB. W/O unlocking the BL

This did not work for me. I have a Nexus 4 with a broken digitizer, locked bootloader, and usb debugging disabled. I need to grab some data off.
I've tried `fastboot flash recovery {{recovery .img}}` and `fastboot boot {{recovery .img}}` without unlocking the bootloader first, and via both methods, I get back "FAILED (remote: not supported in locked device)"
So I'm not sure how people are able to get into custom recovery without first unlocking BL/losing all their data. Can someone explain?

On some (few) Motorola devices (not nexus 4), you can fastboot boot without unlocking the BL.

Hello all! I'm having a problem with a Nexus 7.
This is my brother's tablet that he hasn't used in a few months. It hasn't been unlocked or rooted.
I can get to the boot screen with the android lying on it's back and the options with the volume buttons. The other info on that screen which might be pertinent:
Fastboot mode
Product name: grouper
variant - grouper
hw version - er3
bootloader version - n/a
serial number -
signing - not defined yet
lock stated - locked
When I go to recovery mode and push the power button, it says "booting failed" in the upper left. It still says Google in the middle, and has the options with the volume in the upper right, but the android is gone as is the text in the lower left.
I have adb and fastboot installed, but I can't seem to do much since the tablet is locked. I tried unlocking a few times, and it's always failed. Usually it doesn't give a reason, but one time I got this: "Failed (status read failed (Too many links))"
I've tried googling this and can't find someone with the same problem.
Anything I can try?
Thanks!

If you can get into the Bootloader, just run the below via ADB
Code:
fastboot oem unlock
Once you unlock the Bootloader you can use the "Soft Brick" Mode in the NRT to Re-flash back to stock and see if that will allow you to boot. You do not need debugging enabled to use the Nexus Root Toolkit if you use the Soft Brick mode, but you must have an unlocked bootloader.

What says "unlocking" (computer or tablet) and are you trying to do it through the Toolkit, or via command prompt ADB? I would first make sure your computer is seeing your tablet (ie. that the drivers and Fastboot are installed correctly). Do you know that they are?

I was trying this with the command prompt. I could get fastboot to list the device when using that command. And the tablet and command prompt both say "unlocking" when doing that. I would assume that means the computer is seeing the tablet and everything is set up correctly?
I think I tried to unlock with the Toolkit, but I believe it told me that device needs to be in debugging mode.
Hey there, I'm having a similar problem.
My info is the same except my bootloader version is 4.18 and my lock state says it's unlocked. I tried to use the root kit but I'm having trouble with the fastboot device being detected. Driver solutions attempted were the google ones, and the pdanet ones. I can't really do the manual thing since that involves the device being recognized when plugged in, and since I can't enable usb debugging... anyways the automated drivers windows says were installed successfully so I don't really know what else to do.
Note: I do know the usb port on the tablet and computer work since when plugged in, it will show that its charging with the white battery icon.
Same issue here
I was in the process of upgrading manually from android 5.0 to 5.0.2 owing to the serious lag that came with lollipop. The OTA was taking longer and testing my patience as most apps were crashing due to lag.
Therefore decided to go for manual flashing of the image. I have never done this before. I was able to make the computer see my device by disabling mtp via storage under setting in the device. This is one thin I noticed to make the device visible to the computer.
After installing the device drivers my nexus was visible within the device manager but it couldn't be seen as an external storage until I played with the MTP. I had even unlocked the boot loader before all this.
So everything was going well and while I started to think all is well, I ran into this issue. From adb I tried to run 'flash-all.bat' from the new device image. Something went wrong somewhere - don't know what it is, but from then on, I am stuck in the fastboot screen or into recovery mode but when i try to boot the device bu hitting the power button - I get this message 'Booting failed'.
I am also trying to use NRToolkit but no use. When I connect my device it is seen in the device manager in my pc but cannot see it as a storage. Therefore when I now try to run the 'adb devices' command it cannot see my device. From what I saw initially, until I enable/disable mtp mode adb was not able to see my device to communicate.
Now when I tried NRT and installed the drivers once again, it is being detected in the device manager but when I run the driver test within NRT - I get a ADB device not found error. Within NRT all that it says is go into device setting>storage to enable it which I know but at the current status of my device in boot screen/recovery mode how can I go in to enable this. This is not helpful.
Somebody please suggest a workaround for this issue. I know I am close to the solution but not sure how to enable the MTP or at least made the NRToolkit to say 'ADB device found'.
My fastboot screen shows these details:
Fastboot mode
Product name grouper
Variant = grouper
HW Version – ER3
Bootloader version – 4.23
Baseband version – N/A
Serial number – 015d21d910141c0a

Hi guys,
I recently dropped my Nexus 4 on the floor today and the screen cracked. As a result, the screen is completely unresponsive now but I am able to see its display when I press the power button. Could you guys help me/point me in the right direction regarding how to get the data I have on the phone (music, photos etc.) please.
My Nexus is unrooted/stock version. I tried connected it to my laptop via USB, but all it does it charge. I think I might have the USB debugging option enabled (as I remember enabling it before sometime ago). I'm running the latest firmware (5.0.1 I believe). Also the bootloader is locked.
Any help would be much appreciated.
Thanks
EDIT: I should note that I have a Password (PIN) for the lock screen.
I installed android sdk and tried to enter commands, but it didn't work. When I typed in 'adb devices', no serial came up (I checked sdk manager for the google usb driver, and it says it's installed). Also, when I tried typing in anything i.e. 'adb shell' it said error no devices found. I was attempting to follow a guide to set up adb for any other steps required to get my data from the internal storage. Bear in mind, I don't have much knowledge on these tools, all I'm doing is following any guides. Please can you help me how to get my photos or the contents of the sdcard.
The pin is not letting you boot into the os and that's why adb isn't working. Can you get into the bootloader? If so boot into twrp then try adb
fastboot boot twrp.img. Where twrp.img is the full file name.

Thanks for responding. I can enter the bootloader (if that's the Volume Down + power button menu). Quick google search shows that twrp is for customer recovery. Bear in mind that I haven't unlocked the bootloader or installed anything like recoveries before (it is basically a stock N4). Would I need to install it? If so, please could you direct me to a tutorial or guide me step-by-step on what to do as I don't have too many ideas on what to do to get the data from the phone.
Just to clarify: My N4 is completely stock, Bootloader is locked (says 'LOCK STATE - locked' in bootloader menu) and it is unrooted. I remember having the USB debugging option enabled the last time I was in the dev menu on the phone.

We'll you've got a problem. You'll have to unlock the bootloader to run fastboot commands and that'll completely wipe your device. And with the pin and an unresponsive screen you can't get into the os. There really isn't anything you're going to be able to do to save your files. Sorry about that.
Edit, just one more thought, are you still on 4.4.4? If so there may be a hope. Shoot, you'll need to boot into the os though. So my idea isn't going to work.

Ah that was what I feared ... I'm running the latest firmware (5.0.1). I wouldn't really care about the phone if it weren't for a few images (should have had it backed up!).
Now I need to decide whether or not to change the screen etc. for £35 or just look in the market for a new phone. If I did buy a new screen/digitiser/frame thing, would these be suitable (where I won't need to use heat guns or glue and stuff)?

Also, if I did change it using the above, would dissembling the phone and reassembling it cause my data to be lost?
Thank you for your help
Edit: I managed to save about 80 photos which were probably in the default images folder in the SD card using AndroidLost. I'm guessing the other images which were in other folders i.e. WhatsApp Images etc. aren't recoverable using the site
Hi, I have a S4 i9505 with a problem, screen broken and no display at all + usb debugging is disabled.
Phone: Not rooted, original software, usb debugging disabled, no display at all
What I want to achieve: restore all my photos / videos on the phone memory, no sd card
What I have attempted:
installed ADB & fastboot based on instructions from http://forum.xda-developers.com/showthread.php?t=2786395
What I need help with:
- When i try to get into recovery mode, i wasn't sure if i am indeed in there since i can't see anything, but in total there's a vibration when i turn on the phone, and another vibration when i release the power up+power+home after pressing them down for about 5 seconds.
- When in command prompt I type adb devices and there was none, and when i type adb shell it says error: device not found
I have ensured all drivers for my phone are installed (even with PdaNetA4180 & UniversalAdbDriverSetup6 from cynanogen) but the error remains. refer to attached image.
I have done extensive search on the forum but still couldn't find any ways to get usb debugging enabled on my crippled phone.
Any step by step guide would really be helpful! Thanks
Ps. Main problem = device not found in adb , usb debugging disabled, screen no display/cracked
What do you want? To recover files? To my knowledge that is not possible.
You would first need to flash a custom recovery for adb to work in recovery.
Then you would need to allow the connection on your device (which you can't do).
Yes I need to recover photos only. Nothing else.
Please kindly guide the steps on how to flash a custom recovery (w/o control of the phone's display or touch)
Thanks.

Why not use the mtp protocol and copy whatever you want
Hi, in the beginning, my phone is locked with a pattern pin.
I read the tutorials and managed to get away with the pattern pin by resetting my phone to factory settings via recovery mode i guess by watching youtube guide.
I didn't knew the photos and all will get deleted off from it, so there's nothing to transfer over when i got MTP working and able to access files inside the phone.
What do you recommend? Would fixing the screen and then using dr fone recovery works? or is there any other way to solve this without getting the phone display fixed? Thanks.
If the photos are deleted by the factory reset then i am sorry to day but you cannot recover them even if you get the screen fixed

I didn't knew the photos and all will get deleted off from it, so there's nothing to transfer over when i got MTP working and able to access files inside the phone.
What do you recommend? Would fixing the screen and then using dr fone recovery works? or is there any other way to solve this without getting the phone display fixed? Thanks.

Your photos are gone and there is no way to get them back.
I realize there are many other threads on this, bear with me please, I was not able to find a solution that works.
-display is broken, shows light but nothing else
-digitizer is 99%? broken, back and menu buttons work, there is some heptic feedback in upper part of the screen
-phone does not have a lock pattern or password, just swipe to unlock
-voice commands work
-phone was rooted a long time ago, I don't recall the mehod, I think the current OS is likely 4.4 but i'm not sure (is there a way to check)?
-I had a custom recovery on it which i think was CWM, again, not sure how to check this now
-I can install apps via web appstore
-At some point I installed a clockroot app (never worked) it's probably still on the phone
-I don't have OTG, ordered one
-I don't want to order a new digitizer
Here are somethings that kind of work and some that don't
-dr.fone shows a USB debug promt with instructions on how to accept the RSA key. I'm guessing USB debugging mode is on but it's not the same computer
-if I have the device in download mode, it is "sometimes" recognized by dr.fone, just says its in download mode and asks to reboot
-if I have the device in recovery mode (i think), it's not recognized at all, does not even show up in device manager
-when phone is just on, it's recognized by the computer, I can browse and backup files (i need to backup google auth app)
-with phone on, its recognized by windows and adb, adb says the device is not authorized.
-however adb does not recognize it if I boot into recovery
I think my best best to just to push the rsa key to the phone in recovery but I'm stuck because the phone is not recognized. I will try re-installing drivers next but I doubt this will help.
Lastly, I wasn't sure if I really do have CWM installed or its stock recovery. So I tried to flash CWM using Odin, with phone in download mode, recognized by Odin, the flash fails with an auth error, i'm reading that might mean the phone is not rooted which is 100% not the case here, maybe the rootclock app is doing something to it.
Any advice?
I'm starting to recall the rooting process a bit and I'm fairly sure I used safestrap method, as I was on 4.4.2-4 NJ something kitcat at the time. So I may not have CWM installed after all.
little bit of progress to report. I'm fairly certain i have safestrap recovery on this phone. So booting into recovery must have been bringing me to the safestrap screen that needs a screen tap to recovery or continue. If I hit power it reboots, if its only 2 options recovery or continue to normal boot, volume down move me to the other option, + power....now adb detects the phone! in sideload mode, lets see if I can do something with this, fingers crossed.
no luck, sideloading seems useless. How can i get myself into recovery!?
I think if I can push the adb rsa key I would be set to use one of the screen mirroring apps. How can I sideload it in?
I'll be making a video for this with the 7 inch tablet on Nov. 29th or 30th (depending on the time I have)
General Disclaimer: I'm not responsible if you brick your tablet. This is how I did it personally as other methods here didn't work for me. I have yet to test this method on a 7 inch, also do not have access to the Surf variants. This has only been tested on the 10.1 inch with the keyboard. Will update when I test with the 7 inch.
What's Needed:
MTK Fastboot Drivers: https://online.mediatek.com/Public Documents/MTK_Android_USB_Driver.zip
Magisk Manager Canary: https://forum.xda-developers.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337
Stock Boot Image: https://forum.xda-developers.com/wa...eral/stock-stock-backups-images-otas-t3998227
ADB and Fastboot: https://www.xda-developers.com/what-is-adb/
Prerequisites:
Personally, I had issues getting my PC to recognize the tablets in Fastboot mode. The drivers wouldn't install. This might be optional for some of you, but I thought I'd include it just in case.
Installing MTK Fastboot Drivers from the link above
If you plugin your device in fastboot mode and your PC doesn't recognize it, follow these steps. If it did, skip this part.
1.) Download the drivers above and unzip the Zip file somewhere on your PC (desktop or My Documents is easiest)
2.) Boot your Tablet into Fastboot Mode by holding Vol + and Power, then select Fastboot from the Menu
*NOTE* There is a bug with these tablet's that the volume buttons are mislabeled. Really dumb, but I guess that's why they were 55 bucks for the 10 inch on black friday
3.) Plug the device into your PC and open Device Manager by pressing WinKey+R and typing devmgmt.msc, hit Enter
4.) If there's an Other Device listed called Android, follow these steps. If it isn't there, follow the next set of steps
5.) Open a Command Prompt window as Admin and type the following command
Code:
bcdedit.exe /set nointegritychecks on
6.) Hit enter, then restart your PC
7.) Once the PC is restarted, make sure your tablet is connected in Fastboot mode and open Device Manager again
8.) Right click Android under Other Devices and select Update Drivers
9.) Click the Browse my Computer for driver software button and select the MTK Folder you extracted from the download link above
10.) From there, you can open command prompt, type fastboot devices and see if your tablet shows up and move on to root!
Unlocking your Bootloader
From here, you can unlock your bootloader very easily to Root your device
This will wipe all data off the tablet!
0.) Enable OEM Unlock and USB Debugging on the tablet by going to Settings->About and tap Build Number 7 times. From here, enter the new Developer Options that unlock and turn on OEM Unlock and USB Debugging.
1.) Boot your tablet into Fastboot mode and connect it to your PC
2.) Open a Command Prompt window and type the following command, then hit enter
Code:
fastboot flashing unlock
3.) Follow the instructions on screen to unlock your bootloader
4.) Now Boot your device and we'll move on to making a rooted Boot Image
Creating a Rooted Boot Image with Magisk Manager
0.) Make sure you already have Wifi setup and connected before the first time you open Magisk Manager on your device! Make sure it auto connects as well
1.) Download Magisk Manager Canary from the link above
2.) Install it to your device
3.) Download boot Image from the Stock Boot Image part of the Prerequisites above and put the boot.img on your devices internal memory
4.) Open Magisk Manager and select Install Magisk
5.) Select Patch File and select the boot.img from your internal storage
6.) Once its done patching the image, take magisk_patched.img from the downloads folder of your device and move it onto your PC
7.) Boot your tablet into Fastboot mode and plug it into your PC
8.) Open Command Prompt and type the following command and hit enter (make sure you know your magisk_patched.img file location)
Code:
fastboot flash boot magisk_patched.img
9.) Reboot the device and you'll be Rooted!
Optional Steps like Modules and Debloating
My basic debloat script: https://forum.xda-developers.com/wa...s-general/root-walmart-bloat-remover-t4011639
Will be testing GSI roms on the spare 7 inch and will list those here
Recommended Magisk Modules:
Viper4Android Legacy
FDE.AI
MagiskHide Props Config
Systemless Hosts
Youtube Vanced Black
Magisk Setting to Enable:
Magisk Hide
Rename Magisk Manager App (keeps app from detecting magisk root)
Credits:
Myself for this root method @byproxy for reminding me to add the steps for OEM Unlock and enabling wifi before opening Magisk Manager for the first time
I'll start this off saying i'm an amateur at this, but I cannot for the life of me get an option to show up in magisk to patch the boot image even though it's on my 7" tablet. Any thoughts?
The bootloader was unlocked and it was successful so that's not the issue.
Are you online? I had the same problem.

Sorry, been a busy few days, but make sure you're connected to Wifi, close Magisk Manager, then reopen it and you'll be good to go!
Onn 8" walmart tablet
I purchased the 8" Onn walmart tablet second hand from a store called dirt cheap. Box didnt look to be opened but it had been. The tablet had been setup with someones gmail account that i do not know. The tablet was for a 4yo girl to use to learn preschool. Is there just any simple way to remove this google FRP lock ? I dont care if i lose the info on it as its not mine. I just want her to be able to use the tablet. Any help would be much appreciated please

Forced factory reset should do it. There is small pin hole near the power button. I believe pressing this hidden button(with a Sim card ejector, or paper clip).
If pressing does not do anything. Maybe press the button then hold power button too

Thank you for responding so fast. I've boot into recovery mode /wiped everything...its back to factory. The pinhole reset button does nothing other than reboot it . Ive tried all combos to with the reset button but nothing. Also i've read that its possible to use odin? if i can get it into download mode.
Ive downloaded the stock rom posted on an sdcard wondering if i can possibly update in recovery mode? Im sorta a newb at this stuff. I've been reading for 4 days on this matter. I've practiced a root on an old tablet with success. I guess at this point unless i can sell it as is giving the customer that it has this frp lock on it. If the know how to fix it so be it. Im not sure there is a working solution for frp bypass on these tablets.

This is an mtk device not Samsung. So there is no Odin or download mode. There is spflash tool, and preloader.
And if you flash firmware (with default frp partition) then frp lock is cleared.
But you will have to find that file. It maybe in the stock firmwares that are shared, I do not know.
EDIT:
i was having issues but figure it out. maybe it should be so common knowledge that it shouldn't need to be included as a step, but since i don't do this THAT often i didn't think about it and it took me a bit to figure out why i was having issues.
once you get your computer to recognize your device (mine did without needing to mess with any drivers) you need to first make sure to got into the tablet settings -> about and then tap on the build number 7 times to access developer options. then you need to go into developer options and turn on OEM Unlocking & USB Debugging.
THEN follow the guide to unlock bootloader.
then (since the tablet is factory reset once you unlock) do the above AGAIN to turn USB Debugging back on after you reboot.
also note that you need to have an internet connection on the tablet to utilize magisk. once you got all that square, then continue on with steps for full root.
hope that helps!

I did not realize I didn't include that step. Total noob mistake when typing a tutorial up for android. I do this almost daily at work, so I forget to include it

I was able to remove FRP lock on one of mine by flashing the stock rom with SP Flash Tool. I used the full wipe and download selection with every partition selected including boot.
no worries! i didn't think about it either until i was having issues. thanks for the tutorial... it was super helpful!! btw it definitely works on the 8" tablet.
Hello! I'm new to all of this, but what I'm trying to accomplish is removing the Google account from this tablet and putting a new image on the ONA19TB002, ONA19TB003, ONA19TB007, Surf 7 and 10 tablets. I followed all of the steps as far as installing the drivers. I had to go through hoops to get the MediaTek Drivers installed, but I have a "warning" cone by it. I haven't been able to find any resolution to this. Any help would be appreciated. I' have a Windows 10 64-bit system that I'm using and the tablet I'm specifically working on at the moment is the ONN ONA19TB003 tablet. The tablet is not being recognized by my laptop when I run the 'fastboot devices' command in PowerShell. Is there something that I'm missing? Any help would be appreciated.

Personally, I avoid PowerShell at all costs. This kinda stuff has always just seemed to work better with CMD.exe instead of Powershell.
These tablets are kind of a nightmare for this. If you've done the mediatek drivers and still have the warning cone icon, I'm not sure what's next as I haven't hit that wall myself. All I can maybe recommend is right click delete drivers in Device Manager, then start over with the driver install
Removing the Google Account would be needing a FRP Bypass. Someone above stated "I was able to remove FRP lock on one of mine by flashing the stock rom with SP Flash Tool. I used the full wipe and download selection with every partition selected including boot. " so if you can get it recognized, try that

Ok, thank you! This is a shot in the dark, but in order for ADB to work, USB debugging has to be enabled. I can't do that as the tablet is locked by FRP and I have looked countless times on Google and MSN to see if it's possible. Do you have any tips for that?
I don't know what I'm doing wrong, but for some reason I can't seem to get. The tablet to stay in fastboot mode. It just says waiting for device.

Sorry for late reply. Been away from home with work. When fastboot mode indicates "waiting for device," it generally means that your device is not properly communicating with your PC or laptop. This is nearly always due to missing or incorrect drivers 9n your computer. There are several comprehensive guides here on XDA for installing necessary ADB & Fastboot drivers.
