TeamWin Recovery Project 3.0.2
WARNING #1: Unlocking BL and flashing a custom recovery voids your warranty. Please make sure to contact your carrier/seller if your phone is still under warranty after unlocking the bootloader.
WARNING #2: Make sure you have enabled OEM unlock and unlocked bootloader before trying to flash this. How you can successful root and install TWRP will be described below.
WHAT IS TWRP?
Oh come on, you know what it is - don't try to fool me!
In case you're serious, though...
Team Win Recovery Project is a custom recovery for Android devices.
It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, and root your device.
HOW-TO UNLOCK BOOTLOADER
1. Get bootloader Unlock code here
2. Install minimal adb and fastboot
3. Plug in your phone and make sure all huawei drivers got installed
4. Enable developer options in settings as described above.
5. Enable OEM unlock, enable USB debugging (both in developer options)
6. Open the adb tool you installed recently
7. Type fastboot devices (now a device number should show up)
8. Type fastboot reboot-bootloader (your phone will now boot into bootloader, if not, you haven't set up drivers or adb/fastboot correctly)
9. This step will wipe all your data! Type:
Code:
Code:
fastboot oem unlock xxxxxxxxxxxxxxxx
(xx is for your unlock code)
10. Ones it's done type:
Code:
Code:
fastboot reboot
Your phone will reboot and you have an unlocked bootloader!
11. You can now go on installing TWRP on your device
HOW-TO INSTALL
Make sure you enabled OEM unlock in settings, if you haven't please do that now by tipping 10 times on build number (to activate developer options), than open developer options and go to OEM unlock, enable it
Have an unlocked bootloader is required! (In my case, I login the unlocker website at provide necessary information and get the unlock code so try yourself !!!)
Download the TWRP recovery from the download section below
Make sure you got fastboot drivers installed (I will describe this below in how to unlock your bootloader)
Open the adb/fastboot application on your pc and go to the directory where your TWRP img file is downloaded
Boot your phone into download mode (First method: fastboot reboot-bootloader while connected to pc. Second method: power off your phone, hit power on and volume down until it boots to download mode)
Check again if there is written: unlocked phone!
If yes type now into your adb/fastboot terminal:
Code:
fastboot flash recovery Twrp_CRO_U00_recovery.img
Click to expand...
Click to collapse
Type:
Code:
Code:
fastboot reboot
Now boot into recovery by pressing: power+volume up+volume down at the same time
Enjoy twrp
HOW-TO ROOT
Backup, just in case
Have an unlocked bootloader and TWRP installed from above (take one from december)
We will use this root method: Phh's superuser
Download latest official phh superuser zip here.
Put the zip on your external sd card of your phone (since we can't access /data in twrp)
Boot into twrp and flash the downloaded file
Install latest Material phh apk: Release post
Now you are rooted, congrats!

Root your "Barns & Noble Nook 7" BNTV450 using Magisk's Patch Boot Image File option.
BE CAREFUL!
There are always risks involved when you start messing around with a device.
If something goes wrong, you may end up with a non-working "bricked" device.
This is especially true when you start flashing partitions. (In this case boot.)
Disclaimer
I am not responsible for your non-working "bricked" devices.
I have a few of my own.
Requirements
Barns & Noble Nook 7" BNTV450
A computer with working adb and fastboot
USB cable
WiFi connection
Magisk Manager (Link below)
Stock boot image (Link below)
Tested on:
BNTV450-v1.0.2-20161230 Security patch October 5, 2016
BNTV450-v2.0.4-20170927 Security patch August 5, 2017
BNTV450-v2.0.5-20170110 Security patch November 5, 2017 ota update
macOS 10.13.x
Windows 7 Pro
Steps
Unlock bootloader
Boot Magisk patched boot image
Pull stock boot and recovery images from device
Use Magisk to patch pulled stock image
Test and flash new patched boot image
Notes:
Google updates were needed to get everything working correctly.
PlayServices and WebView
Mac users. As with some other devices, I had to unplug and plugin the USB cable between some of the fastboot commands.
fastboot flash boot patched_boot.img and fastboot boot bntv4-recovery.img
Magisk:
There have been a lot of changes in Magisk since I originally used it to root.
Way too many to mention so, just the basics that apply to this device.
Newer versions of Magisk use the Download directory instead of creating and using the MagiskManager directory.
Some apps search for this directory and used it to determine if the device is rooted.
If you previously used Magisk to root and have a MagiskManager directory, you will want to delete it.
To update Magisk Manager.
Use the update option, it will download and install the newest version.
To update Magisk.
The safest way is to patch the boot image again. Test and flash.
The Direct Install option works but, may lead to a non-desirable outcome.
To uninstall Magisk.
Test boot your original boot image to make sure it works.
Check with Magisk Manager, it should say Magisk not installed.
If so, then flash your stock boot image back using fastboot.
If your stock boot image will not boot, then you are stuck with Magisk patched boot images.
Hardware Keys:
Power and Volume Up = Recovery Mode
Power and Volume Down = Factory Mode
It will show on the bottom Left (Sideways on the top left) Detecting boot mode. With bootloader unlocked it flashes this message very fast so you might not see it.
I still can not produce the same results continuously across mine. The newer ones, that came with v2.0.5 seem to work but, the older ones still it's a 50 % chance if I can get it to work. The bricked ones, do not seem to register the key combo on boot.

Unlock Bootloader
THIS WILL VOID YOUR WARRANTY.
Unlocking the bootloader WILL wipe and Factory Reset your device. Make sure to copy, backup and logout of everything before you begin.
Note: adb and fastboot need to be installed and working.
On device
Go to Settings - About and tap on the build number seven times to enable Developer options.
Go to Settings - Developer options and Enable OEM unlocking and USB debugging

On computer
Code:
adb reboot bootloader
Wait for device to boot into fastboot mode then.
Code:
fastboot flashing unlock
On device
Follow the prompts on the device.
Unlock bootloader?
If you unlock the bootloader,you will be able to install custom operating system software on this phone.
A custom OS is not subject to the same testing as the original OS, and can cause your phone and installed applications to stop working properly.
To prevent unauthorized access to your personal data,unlocking the bootloader will also delete all personal data from your phone(a "factory data reset").
Press the Volume UP/Down buttons to select Yes or No.
Yes (Volume UP):Unlocking(may void warranty).
No (Volume Down): Do not unlock bootloader.
After it returns to fastboot mode, use the power button to turn off, unplug it from computer and then turn on.
It will reboot a few times, including an Erasing... screen.
Once device reboots, run through the initial setup.
Note: Sometimes mine would get stuck on the nook .... animation screen. Give it a few minutes (I wait at least 5 minuets) then power off and power back on.
Note: You will now have the annoying boot delay and "Orange State" message.

volume button does not react
Hi
unlocking does not work
As mentioned in the other discussion, the volume up button does not seem to react and so the unlocking does not work. Also one user suggested using the reset button after pressing the volume up button for the unlock; that also does not work for me
Do u have any other suggestions to unlock ?;

I never ran into this problem. So short answer - No.
Can you point me to that other discussion?
What do you get if you run fastboot oem lks
fastboot oem unlock is supported on this device. You could give that command a try and see if there is a difference.
Not sure what you have tried.
I would start with "Factory Reset" in stock recovery. Skip through the initial setup and try again.
Note: Developer option menu has a toggle at the top, make sure it is turned On.

Volume up button not recognised while fastboot unlock
Hi
Here is the discussion thread that I was referring to where people are stuck with unresponsive volume up button for fastboot unlock
https://forum.xda-developers.com/nook-7/help/nook-rootable-t3510289
I didn't do the factory reset. So maybe I will do that and see if it works.
unlock not working
Hi
Just to further update you on your reply; i did a factory reset and tried to unlock the bootloader but i get to the same problem; the volume button does not respond; so stuck with the message 'press the volume up button to unlock the bootloader'
I did the fastboot oem lks and that commands executes well and it gives me a OK output.
Cheers & New year greetings!
Any update on the unlock issue
Hi
Is there any update on the unlock issue i reported some time back? My last update on this was executing the command => 'I did the fastboot oem lks and that commands executes well and it gives me OK output.'
not sure if my last update was interpreted in the right way; it does nothing when i type fastboot oem lks except saying it is OK (which i suppose is the expected output of fastboot oem lks). So i do not know how to get around the volume keys not being recognised to go further in unlocking
I still can not use the volume keys for the unlock as it does not seem to react. just stuck a bit on this
@arrmusic I guessed it it looked more like this.
Code:
fastboot oem lks
...
(bootloader) lks = 1
OKAY [ 0.000s]
finished. total time: 0.000s
lks = 0 would be unlocked.
I am looking for a way to un-brick these. I think that may be the best way to correct the button problem also.
What os version are you running? (BNTV450-vx.x.x-20xxxxx)
What do you get when you run fastboot flashing get_unlock_ability ?
Tested a few things tonight.
I was NOT able to re-lock the bootloader on either of my rooted devices.(BNTV450-v2.0.4)
Found some more inconsistencies with power and volume key boot combinations. (Among other things.)
"FAILED (remote: not support on security)" apparently is not just for unlocked devices.

Hi
Many thanks for your reply.
I seem to have the software version v1.0.2;
I tried to find by googling v2.0.4 but i am not able to find that security update anywhere to download; do you have the v2.0.4 file? can i have it somehow?
I ran the commands u had mentioned in your previous reply.

v2.0.3 boot came from a supposed "N" rom for this device and was the first boot image I was able to make bootable. It was still API 23 "M" by the way.
I would have to find and unpack the original file to see what I edited to make it bootable.
All others are "dd" copies from my own device(s).

Scatter file for Mediatek MT8163, opening the tablet
Can you post the scatter file for the Mediatek MT8163?
I've been trying to make my own image dumps for the Nook 7, but have run into an issue where the device won't stay in a readable mode for SP Flash Tools long enough while the battery is still connected. So, the solution for most phones is to disconnect the battery and have it powered over USB only so that it won't go past the preloader and into the charging mode.
But I can't get the darned thing open! My phone has a similar style housing and I had to use a suction cup on the glass while prying at the edges to gain access. But for the Nook 7 its just not working.
Edit: This started while trying to soft load TWRP to make the image dumps. When I do
Code:
fastboot boot twrp.img
It tells me that the kernel address lies outside of memory. Its possible to supply an address to load it at with the fastboot command which you are supposed to learn from the scatter file. I found what I thought was a valid MT8163 scatter file but using the address found within did not fix the issue.
I forgot you mentioned that you didn't pull the original image from your device yourself. I've been trying to root this without relying on images from others. Your latest guide to pulling and modifying your own boot.img is a decent enough middle ground for me to use. Thanks.

I was able to get a successful root by following the steps in this thread in combination with those mentioned in this one. ipdev, just to satisfy my curiosity, where did you find this "N rom" image?

So we hit a snag using Magisk 15.4+ to patch a stock boot image on this device.
Click to expand...
Click to collapse
So, I was dumb and went through with updating Magisk without checking this thread first, and now my tablet's stuck in a bootloop that I can't seem to get out of. @ipdev, do you have any ideas on how this happened/how to get out of it? The tablet can't get past the "Orange state your device has been unlocked etc. etc." screen, and I can't get it to boot into recovery either (using Power+Volume Down, is the combination something else on this tablet?). fastboot won't discover it either, probably because it reboots within seconds and never gets to a point where it could be recognized. I'm thinking of letting it bleed out until its battery dies (unfortunately, the battery is soldered and glued in, so I can't just disconnect it), and checking on it in the morning to see if it will be cooperative enough to let me flash the modified Magisk image.
@saagarjha
I have a few in the same condition. As you noticed, the battery is soldered in so the best you can do is disconnect the screen. (Connector to the right of battery.)
One of these days, I was going to try sp flashtools to see if I could recover one of mine. (I'm not sure if it works with these.)
Sent from my Nexus 5 using XDA Labs
I let the tablet run out of battery and then plugged it back in again and it immediately got stuck in the same bootloop, so it looks like it's actually bricked rather than just pretending. I think SP Flash Tools is the way to go at this point; we'd have to find a functioning preloader driver and scatter file to do that, however. It might be possible to simulate disconnecting the battery by shorting the battery's leads, but I'm not sure if this would work (or is even safe to do).
I was having trouble with unlocking the boot loader on my v1 launch version of this Nook. Recently I dropped it and got a new one via the replacement plan - this one was marked 'v2', came with a 2.x firmware that I wasn't able to even get on my launch Nook 7.
Anyway, this one unlocked without any problems. Thought this might be helpful to anybody having trouble unlocking the bootloader. Consider the revision of the Nook you have. Maybe the solution here is flashing the v2 firmwares to the v1? Hard to say.
unable to unlock
So I did "adb reboot bootloader" and the tablet rebooted and says "=> FASTBOOT mode..." on the screen.
I then did "fastboot flashing unlock" on the computer. Nothing happened on the device and my computer says "< waiting for device >". Could anyone please let me know what I did wrong? Thank you very much.
There are a lot of other threads in XDA telling you how to unlock your beloved LG G4 bootloader. But then i felt it was too hard for new people to do it.
So this guide makes it EASIER for you !!!!
WARNING
I WON'T TAKE THE RESPONSIBILITY IF YOU END UP BRICKING YOUR DEVICE.
UNLOCKING BOOTLOADER WILL FACTORY RESET YOUR PHONE. SO BACKUP ALL DATA.
Now in your Stock Lg G4 settings, go to about phone and software and then tap on build number until you become a developer.
Now a new option will appear "DEVELOPER OPTIONS" in settings.
Go inside it and turn on usb debugging and also enable OEM unlock in it.
Now we need a pc for unlocking bootloader.
Also we need a set of adb drivers which you can search google and get the 15 sec adb installer.
After getting them all, you are set to unlock your bootloader.
Connect your phone to your PC and enable USB debugging (WORKS ONLY IN MTP MODE)
Then open CMD or PowerShellWindow and type the follow commands into it
Code:
adb reboot bootloader
When you enter Bootloader, you can see some commands on the top left of your phone.
Run them in your CMD
These commands will unlock your bootloader..
Restart your device and you will see that your bootloader would be unlocked and everything would be erased.
Now for rooting the phone,we need TWRP.
Now again go to CMD and type
Code:
adb reboot bootloader
Get the twrp.img for the lg g4 (H811/H815) from twrp.me
Now in your PC, place the Twrp.img where you have installed the adb fastboot drivers.
Open a cmd in that folder containing adb drivers..
Now type
Code:
fastboot boot twrp.img
Now twrp.img is the name of your file..You can rename it to recovery.img or G4.img
Now this will boot your phone to recovery.
THIS DOES NOT REPLACE YOUR OLD RECOVERY.
Once you are in TWRP,
Allow modifications for the first time and then go to Install... Get the Supersu.zip from the official website (Google Knows)
Put the zip in the root of your sd card where you can find it easily.
Go to install and install the zip.
Congrats... You have rooted your phone
If you want to flash twrp permanently, just keep the g4 into the root of your sd card
Now run the command again that i gave for booting your phone into twrp from bootloader.
It will boot again into twrp and now go to install and select INSTALL IMAGE.
Now select the G4.img or whatever .img file you have for your recovery(FOR LG G4)
Now install it to the recovery partition..
THATS IT
You got your phone rooted... Also you got a custom recovery.
This method has been tested on my LG G4 H811 and it is working awesome till now..
CLICK THE THANKS BUTTON IF I HELPED YOU
10000000000 thanks man
but what 2 do if the mob keep rebooting....and keep on lg logo
There's a ton of information out there, but finding it can sometimes be a challenge, especially for a newbie. And then there's posts to read through, in case a process has changed and it's only talked about in a single place, buried any number of pages back. So this is my attempt to put all Pixel 3 how-to's into a single thread. Everything below is what worked for me, from start to finish, with a fresh phone directly from Google that was bootloader-locked, unrooted, and running stock Android. Comments are welcome and encouraged: if something doesn't work for you, or you have a better/quicker/more reliable way of doing something, or maybe I made a mistake...let me know!
A few things:
Everything in this guide was tested on a "regular" Pixel 3 (blueline). It should all work exactly the same on a Pixel 3 XL (crosshatch), as long as you download the appropriate files (specifically the factory/OTA images and TWRP). I'm posting this in both blueline and crosshatch forums.
This first post will have links to files and the tools you need, as well as general things (like how to enable debugging and boot into recovery). The second post has how-to's for the big stuff (flashing images, TWRP, unlocking, etc).
I'm not responsible for anything you do. Follow these guides at your own risk. Doing so may also void your warranty.

General
Enable USB debugging
Download Google USB drivers (see above)
Download SDK platform tools and copy required files to their own directory (see above)
Enable USB debugging (Settings > About > tap Build 7 times > back > Developer options)
Plug phone into computer and when "Allow USB debugging" box comes up, check the box and allow (may need to have adb daemon running on the computer already, see below)
Fastboot mode (using hardware keys) aka bootloader
Power off
Hold VOL- and press/hold PWR until bootloader (fastboot) comes up
Recovery mode (using hardware keys)
Get into Fastboot mode (see above)
Use VOL buttons to find Recovery in the list, use PWR to select (should boot to broken android image)
Hold PWR and press VOL+ once to get into recovery
Useful ADB and Fastboot commands
Enable USB debugging (see above)
ADB (used while phone is "on" and booted up):
Use "adb devices" to ensure the computer is authorized
Use "adb reboot bootloader" to get into Fastboot
Fastboot mode
Use "fastboot devices" to verify computer can see your phone
Update #1: Items below marked through were removed since they don't really apply to Android 10.
Update #2: Edited to reflect changes in root with Android 11.
A quick note: everything below is assuming you're using Windows 10. When it says "Type...", this assumes you've opened a command window in the location of adb/fastboot and that all files referenced are in the same directory and (in some cases) renamed as I reference them (short names without spaces simplifies things). If you're using Powershell, you will probably need to change "adb" and "fastboot" to read ".\adb" and ".\fastboot" so Powershell will use the local files.
Unlocking the bootloader
THIS WILL WIPE YOUR PHONE, SO MAKE SURE EVERYTHING IS BACKED UP!
In Developer Options, enable OEM unlocking and confirm (it may ask you to input fingerprint or PIN/pattern/password)
Boot into Fastboot mode (see above)
Type to unlock:
Code:
fastboot flashing unlock
Use VOL+ key to get the options on the screen to read "Unlock the bootloader" and use PWR button to select
Type to reboot:
Code:
fastboot reboot
Locking the bootloader
THIS WILL WIPE YOUR PHONE, SO MAKE SURE EVERYTHING IS BACKED UP!
Boot into Fastboot mode (see above)
IMPORTANT: restore stock recovery if you replaced it with TWRP (this should prevent the "Can't find valid operating system" issue)
Type to lock:
Code:
fastboot flashing lock
Use VOL buttons to find "Lock the bootloader" and use PWR to select
Type to reboot:
Code:
fastboot reboot
Factory reset via fastboot (can also do this without wiping data)
THIS COULD WIPE YOUR PHONE, SO MAKE SURE EVERYTHING IS BACKED UP!
Download factory image ZIP and unzip all files into their own folder
Unlock bootloader (see above)
Reboot into Fastboot mode
You have 2 options:
Register the location of fastboot.exe with the PATH system variable and run "flash-all.bat"
Wipe data: just run "flash-all.bat" and call it a day
Do not wipe data: open "flash-all.bat" in a text editor (careful not to double-click and run it!), remove the "-w" from the last line to disable the wiping of data, then save, close, and run
Move the 3 files (bootloader IMG, radio IMG, image ZIP) into the ADB folder, rename for simplicity if you want, launch cmd or Powershell, and run the commands below (which come from "flash-all.bat")
Wipe data: type out commands below, but at last line, add "-w" flag: fastboot -w update image.zip
Do not wipe data: type out commands below as written (no "-w" flag)
The commands:
Code:
fastboot flash bootloader bootloader-blueline-XXXX.img
fastboot reboot bootloader
[wait for reboot]
fastboot flash radio radio-blueline-XXXX.img
fastboot reboot bootloader
[wait for reboot]
fastboot update image-blueline-XXXX.zip
Note: The last command (update image) will launch the red "fastbootd" screen, so don't worry and be patient while the command line tells you what's happening. The phone will reboot on its own into the Android system (not fastboot) afterward.
Root Android 10+ using Magisk (Canary channel)
This must be done after every update, and you cannot use the patched file from a different phone!
Unlock bootloader (see above)
Download factory image (not OTA, see link above)
Download and install Magisk Manager Canary (see link above)
In Magisk Manager settings, set Update Channel to "Canary"
Extract boot.img from image-blueline-XXXX.zip found in the factory image you downloaded
Place boot.img on your phone's internal storage
Open Magisk Manager and do:
tap "Install" button (next to "Magisk" in first block on the main screen)
"Select and Patch a File" option
Find boot.img file you just placed on your phone
tap "Let's Go"
When finished, move the newly-created magisk_patched.img file over to your computer's ADB directory
Reboot into bootloader
Type:
Code:
fastboot flash boot magisk_patched.img
fastboot reboot
Open up Magisk Manager and make sure everything's good!
Note : if you get stuck in fastboot mode or in a boot loop, flash the stock boot.img to both slots and try again
Code:
fastboot flash boot boot.img --slot all
Optional:
for adblocking, tap "Systemless hosts" in Magisk Manager, then install AdAway using F-Droid
install a performance kernel like Kirisakura for Bluecross (R)
Updating Android 10+ while rooted
You can't take an OTA while rooted, so updating Android 10+ (as in monthly updates) can be one of two ways.
Method #1 (faster, but more chance for issues)
Download OTA ZIP and move it to ADB folder (don't unzip it)
This does not require an unlocked bootloader, but does require USB debugging (see above)
Get boot.img from the factory image (see first post on where to download this) and place your ADB directory
Reboot into bootloader / fastboot and type to restore stock boot to both slots:
Code:
fastboot flash boot --slot all boot.img
fastboot reboot bootloader
[wait for reboot]
Use VOL buttons to select "Apply update from ADB"
Type (where filename is the name of the file you want to sideload):
Code:
adb sideload filename.zip
Wait for it to finish, will take you back to Recovery when it's done
Reboot using menu
Method #2 (takes longer, but best bet for minimal issues)
Follow "Factory reset via fastboot" instructions (see above, make sure you don't wipe your data!)
Take the OTA in the official way (through Android)
Follow "Root Android 10+ using Magisk Canary" instructions (see above)
Boot into TWRP (3.3.0-0 or higher)
Download TWRP IMG and place in ADB folder (rename the file to twrp.img)
If not already done, unlock the bootloader (see above)
Reboot into bootloader
Type to boot TWRP (it will restart and should boot into TWRP):
Code:
fastboot boot twrp.img
OPTIONAL: Replace recovery by installing TWRP
Your phone should automatically mount, so move twrp.img from PC to Download folder on phone's internal storage
Advanced > Install Recovery Ramdisk > choose TWRP IMG > Swipe to install
Back > Fix Recovery Bootloop > Reboot System > Do Not Install when asked if TWRP should install app
Root using Magisk (18.1 or higher)
Download Magisk ZIP and move to device
Boot into TWRP (see above)
Enter your PIN/pattern/password to decrypt (unnecessary if you are not using security on your phone)
Swipe to Allow Modifications (to system)
Install > find and select the Magisk ZIP > Slide to install
Wipe cache > Reboot system > Do Not Install when asked if TWRP should install app
Open Magisk Manager to verify latest and to install modules
"Can't find valid operating system" booting issue
Unlock your bootloader again (see above)
Follow steps for "Factory reset via fastboot" (see above) and keep the wipe flag
After it reboots, power off (press PWR and select "Power off" from menu)
Follow steps for "Locking the bootloader" (see above)
After it reboots into Fastboot mode, have it start using the PWR button
Android Recovery / "Cannot load Android system" booting issue
This can happen for a number of reasons, but the fix is the same: "Factory reset via fastboot" (see above). You probably do not need to wipe user data, so you can omit the "-w" flag.
If you still get the error message, select the "Try again" option. If it still doesn't work, try "Factory reset via fastboot" again, as well as "Try again". If it doesn't work this time, you probably have no choice but to do a factory reset (in which you will definitely lose your data).
If it happens after flashing Magisk in TWRP, though, you've got a slightly different issue and the problem will persist no matter how many times you flash the factory images and re-install Magisk. This is probably due to something leftover in the previous Magisk installation that conflicts with the new installation. There are two ways to handle this.
First and easiest: uninstall Magisk Manager app before rebooting into the bootloader and running fastboot commands. Then proceed as usual (sideload OTA or flash factory images via fastboot, boot TWRP, and flash Magisk). All guides for this are above. This method preserves any modules you have installed.
Second and more complete (if the above method still gives you trouble):
download to your phone the Magisk ZIP, Magisk Uninstaller ZIP, and Magisk APK from this XDA thread
uninstall the Magisk Manager app
reboot to bootloader
using fastboot, boot into TWRP using IMG (you don't need to replace boot with TWRP)
flash Magisk Uninstaller ZIP
wipe Dalvik
flash Magisk ZIP
wipe Dalvik
reboot system (do not install TWRP)
install Magisk Manager APK and re-install any modules
I just have a couple questions pls-
1) Do the above instructions work on the Verizon Pixel 3 XL
2) I'm currently runned the official Android Q Beta (April 5). Do I need to leave the beta, then restore back to stock Android P (and do I do all those updates before starting root instructions)?
Should I be concerned if my phone hasn't informed me of an April update?
I don't remember if I unlocked the bootloader before or after the updates to the March security update. Does it matter?

No it does NOT matter which build you unlocked your BL
*edit*
Try to go into settings and force the update or you can always flash the entire factory img for april

1.) If you somehow have an unlocked bootloader, yes, it would work for the Verizon Pixel 3 XL. However, I was under the impression that Google will not unlock the BL for the Verizon variant and there is currently no way to "hack" it.
2.) It should work the same whether you're on P or Q, though if you want to remain with Q, make sure you download the beta files directly from Google (rather than the P images) and use Magisk 19.0 instead of 18.1.

You can force it to check for updates; when you unlocked the BL shouldn't matter if you're using a patched boot image.

I haven't done anything to the phone since I got it 3 weeks ago but hoping to. Can the VZ version be unlocked? If so please point me in the right direction.

Thanks so much for the info! Its difficult trying to find the current status of all the diff devices' root statuses.
Thanks for this guide, when using the flash-all.bat and wiping the device will this method flash to both slots?

yes, if you are flashing with wipe all option (without removing -w) it does flash to both slots.
Regarding getting to fastboot:
Since I have flashed April security update and after lightly bricking my Pixel 3Xl, (I have not lost data but I was unable to boot till solving the brick), the phone doesn't stay in fastboot when I use the adb command to get into it and all I can do to get to stay in fastboot is the power and volume down combo for more than 40 seconds.
I have my pixel working perfectly with root and kirisakura kernel but it is a bit of a pain getting to boot TWRP from fastboot for flashing stuff.

yeah if i try to get into fastboot directly from a power on state it doesn't stick on fastboot blinks for a second and then starts with reboot process, probably we are pressing it too long.
what i do normally is to power off the device first wait for few seconds then then use key combination to get it to fastboot from power-off state. Booting from fastboot to twrp never had any issues unless i had messed up the twrp installation due to some mess i did.

I have to press the keys 40 seconds even from power off.

definitely not 40seconds from power off state for me. not sure whats happening there
Maybe a short video would be a help to some of us newbies
Dumb question. Probably gonna upgrade from an original Pixel XL soon. As long as I buy it from store.google.com, I should be able to unlock the bootloader without worrying about a crack/hack, correct? Thanks!

That is correct. I made the same switch from an OG Pixel and Pixel XL to P3 and P3XL right after release. Unlock the bootloader before you mess around a lot since it will do a factory reset.
How about backups? Does anyone backup and restore, or not?
If so, how do you do it with this 2 partition system?
installed and I like it. I cant get the clock off the lock screen. all settings says it is off.
wished it had MicroG installed instead of gapps
Can't OEM Unlock, can't fastboot flashing unlock, can't boot to recovery, can't fastboot flash boot boot.img, can't fastboot flash recovery recovery.img (like twrp) due to bootloader locked
Is there any way to flash this thing and make it work? Otherwise I'm just gonna throw it on ebay dumb cheap

Enable dev options(settings>about phone>build number>tap it 7 times).
Go into settings>system>advanced>dev options>oem unlocking, click the toggle.
While still in dev options scroll down a little and enable usb debugging.
Plug your phone into your pc.
if/when the phone asks you to trust the computer make sure to check the "always allow this computer" check box.
Open up command prompt type into the cmd window
adb reboot bootloader
The phone will reboot into fastboot mode.
Now type into the cmd window
fastboot devices
See if it lists a device, if not you need to install the drivers I linked to. If you had to install the drivers try the fastboot devices command again after installing them, it should list the device now.
type in
fastboot flashing unlock
You will then have to use the phone to select yes to the unlock. you use the volume keys to select and the power button to confirm.

You didn't read my post title or post at all... There's no OS on the device. Its not possible to get into the system to enable OEM unlock. Can't fastboot flashing unlock, doesn't work, can't send via OTA ADB Sideload as it fails around 10%.
Everything you stated above, I tried
