[HOW-TO] Root BNTV450 Nook 7 (ST16C7BNN) using Magisk.

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.

"QUICK" Guide - BNTV450 Nook 7
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
Connect to computer and Allow 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.
Orange State
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds

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.

What is the origin of the boot.img?
What is the origin of the boot.img? I'd rather not just flash something without knowing where its come from.

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.

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.

[UNOFFICIAL][DECRYPTION WORKS] TWRP 3.3.1 for UMIDIGI F1 [20191103]

Introduction
This is an UNOFFICIAL TWRP port for UMIDIGI F1 that works properly with encrypted /data partition in official ROM. I am aware that the UMIDIGI F1 already has TWRP built for it, but none of them seem to have decryption working properly. In fact, every single TWRP, even official ones, for any MT6771 device, seem to have non-functional decryption support. Through some digging I managed to fix decryption at least for UMIDIGI F1, so here is my version of TWRP for the device.
Known Bugs
- Screen may flash on the password-input UI. Anything else is fine though.
This TWRP has been tested with official ROM and my LineageOS 17 port (https://forum.xda-developers.com/android/development/unofficial-lineageos-17-0-umidigi-f1-t3997827) and it works fine.
This is UNTESTED on the F1 Play. ONLY TESTED on regular F1.
Why Bother
Because security matters. Using a cheap device should not mean giving up security, and more importantly, privacy.
Instructions
1. Unlock bootloader
2. Enable ADB debugging in system
3. Execute "adb reboot bootloader" while having your phone connected to PC
4. Execute "fastboot flash recovery <your_downloaded_recovery>.img"
5. Reboot phone while holding Volume Up + Power buttons
Note: The official ROM may overwrite the recovery, so you may need to re-flash the recovery if this behavior isn't prevented either by TWRP or manually.

I appreciate your sharing this. I have added "system_image emmc" to the fstab file, so I can flash and backup the system.img
This works good on my F1,
But I tried to make this decrypt work for my other phone with 6771(Bold N1), but couldn't find all same files added to recovery/root from stock firmware.

Those files are extracted from vendor.img, but it can be different on different devices, e.g. keymaster version might be different. Also you will need to patch them using `patchelf` to make them use `/sbin/linker64` instead of `/system/bin/linker64`

Cause i test it without changes , it reboot to system
I think because they have different kernels

I am unable to install twrp.
When I run the "fasthboot flash recovery" command, cmd aparace "waiting for de ice" and nothing happens on my phone ...
Am I doing something wrong?

no fastboot response
for some reason (most likely pilot error, lol) the phone doesn't show when I do "fastboot devices" - even though the F1's screen shows "fastboot mode" in very tiny letters on the bottom-left.
probably something stupid I'm doing wrong, will keep trying...

You can operate from adb/fastboot folder and device can stay on fastboot mode but if drivers were not properly installed then no connection with pc.
Try installing:
- https://androidmtk.com/download-15-seconds-adb-installer
- https://androidmtk.com/download-mtk-usb-all-drivers
- https://www.androidweblog.com/download-mediatek-usb-vcom-drivers/
Start the process from device on using adb commands to always allow access to the pc. I mean:
Code:
adb devices
and then if device is detected you will see a screen warning to "always allow...." then tap on yes; this suppress future conflicts, then
Code:
adb reboot bootloader
while on fastboot follow with
Code:
fastboot devices

adb was already working (is how I made the thing reboot to bootloader, and yes I did tell it to permanently accept the computer I'm using.
this is on linux, so the drivers shouldn't be a problem... although SMH I never put USB IDs into the udev rules. which is interesting, because regular adb already worked fine without it - I have had phones in the past that some did, some did not, require the computer to know about vendor/hardware ID.
(and I know that the adb USB IDs are usually different than the ID for fastboot, as well.)
like I said, pilot error lol. but thank you again for the reply!

I have done the following:
Enabled Developer Options
Enabled USB Debugging
Enabled OEM Unlocking
Unlocked the bootloader with:
Code:
adb reboot bootloader
fastboot flashing unlock
Rebooted and Enabled USB Debugging again.
Then after downloading your recovery
Code:
adb reboot bootloader
fastboot boot ~/Downloads/recovery.img
But nothing happened.
I rebooted and thought I would try flashing
Code:
adb reboot bootloader
fastboot flash recovery ~/Downloads/recovery.img
It just paused on the boot screen saying "Your device has been unlocked and can't be trusted".
If I reboot then try to go direct to recovery:
Code:
adb reboot recovery
I end up with the broken android screen and "No command"
What am I missing?

While in fastboot the first you should do is see if device is detected by pc with
Code:
fastboot devices
It looks like something is wrong with your path, I ever avoid path copying or moving the file/image to the adb/fastboot directory but anyway if you don´t want to do it you can copy the path from the bar where your recovery file is allocated, for example, if the file is in Downloads directory like it seems actually is, no matter what unit/drive you are in you can set an absolute value to avoid errors, look at this example: C:\Users\your_user\Downloads
If your device is detected then you can flash the recovery as you were trying to do it with
Code:
fastboot flash recovery recovery.img
and then you can reboot directly to it without need to reboot to system previously and this will prevent TWRP from being overwritten, with
Code:
fastboot boot recovery.img

hmm, so when I checked the udev rules, it already had one for MTK/mediatek - and the USB vendor is '08ed' in fastboot as well as in regular adb, so it wasn't a problem with udev/plugdev.
which I guess may mean the lunix generic android drivers for fastboot might be... "lacking" - I'll have to scrounge up a win7 laptop and try the recommended windows drivers.

I don't think it was anything to do with the path as it output the file transfer size.
I think it was a combination of the following:
I wasn't pressing the right combinations of buttons after flashing.
i.e. holding VOL UP and pressing POWER on the screen saying "Your device has been unlocked and can't be trusted".
Rebooting might (?) have been reverting the recovery.
I was originally trying this on the firmware that was shipped 2019012414 but after flashing 2019090418 with SPFlashTool I had more success.
I also able to reboot to recovery directly after flashing with fastboot with the following:
Code:
fastboot oem reboot-recovery
Whichever was the key I can now reboot to recovery from adb too.

Your twrp eliminates fingerprint authentication.
I discovered something interesting, your twrp only works on my device, no other twrp works, but when I install it, I lose my fingerprint, it doesn't work at all.
Simply put, I must choose between the fingerprint or the root.

Try to clean flash last vendor build with spflash tool. First boot need stock recovery.
You don't need custom recovery to achieve root.
Maybe give a try to SNwriter (I never needed it though and can't help here).

Both of those twrp are not sticking. I have flashed with spoken flash tool v5 1944 win and I fastboot cmd with the same results.

Thanks
Gracias for this master ?

Hi, bro. I tried yesterday this method and worked for me.
Boot your phone to bootloader.
In adb/fastboot type this command: fastboot devices
Then it will show you the serial number of the device.
Copy it and go to the generator page, paste it there and now you have the key.
Now you just have to type the command: fastboot oem key "Here your MD5 hash key"
Now go further.

Now My nokia 3 Bootloader is unlocked and is showing orange state your device is unlocked and cannot be trusted and will boot in 5 sec
After that I tried to install twrp recovery it shows finished in my cmd window but when I try to boot to twrp recovery using command fastboot boot twrp.img my system doesn't boots into twrp recovery after that I tried to poweroff and boot to twrp recovery using volume and power buttons then also it doesn't boot to twrp recovery
Please give me a solution for this

Hello, your post is for TA-1032 for Android 9, I have TA-1020 Android 8.1.0, but I tried this and nothing changed, it just fails the unlock, even after I put the oem key.
You seem like you're good and you know what you're doing, can you please help me? https://forum.xda-developers.com/nokia-3/help/rooting-nokia-3-ta-1020-android-8-1-0-t4077501
Thank you so much.

It worked!
Thanks for the help. Still works in april. To clarify for others - the number that you need to put in the hash generator is the number that you get when you type *fastboot devices*.

Do you have TWRP for Nokia 3 on Pie, I got it installed on mine but when I reboot into recovery mode it's show the No Command screen. I wonder do you get TWRP on your device?

I haven't tried it yet in fear of bricking my device. What do you mean you got it installed? Can you boot into it at least once before it gets replaced with the stock recovery? Cus if you want twrp to be permanent, you need to flash root on your device. Also if you can't get it working on pie try downgrading as there are many threads for previous versions.

Not working, adb device in fastboot shows blank. nokia 3 drivers are installed, oem unlock enabled. Nokia 3 - 1032, Android 9.

I have unlocked bootloader, TWRP, Magisk & removed encryption on Android 9.0 April security patch succesufuly. I tried to flash TWRP with SP Flash Tools but it just reverts back to stock recovery with No Command screen like you said. To install TWRP, use fastboot instead with fastboot command "fastboot flash recovery twrp.img". It works. To remove encryption, first format data than flash this in TWRP: https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389 This also solves issue with TWRP when TWRP can't read Internal storage. After that flash Magisk. That's it.

You need to patch the boot.img by magisk then flash the twrp.img it will work...
In the version of Android 8.1 Oreo and 9.0 Pie boot.img patched required to boot Custom recovery TWRP....

[GUIDE] Unlock bootloader without losing user data.

Hi, I am writing this guide because many people followed other guides in the forum and lost their data. This is the proper way of unlocking the bootloader without losing your data.
0 - Read the whole guide before proceeding and proceed at your own risk!
1 - Make sure you have adb and fastboot installed on your device,
For Windows follow this guide (I suggest installing it system-wide, so that you can execute commands from every directory on your PC): https://forum.xda-developers.com/showthread.php?t=2588979
For MacOS and Linux : https://www.xda-developers.com/install-adb-windows-macos-linux/
2 - After the required tools are installed go to Settings -> About Phone on your phone and keep tapping on build number until a toast notification tells you that the developer settings are enabled.
3 - Go to Settings -> System -> Developer Settings and enable OEM unlocking option.
4 - Turn off the phone and when it's fully off, hold power + vol down button to boot into fastboot mode. When you've done this step successfully, you will see a blue FASTBOOT text on the screen with a bunny scrambling the internals of Android.
5 - Connect your phone to your PC and open a CLI/terminal/PowerShell window and type this but do NOT hit enter :
Code:
fastboot oem unlock
when you are ready to execute the command, start pressing only vol down button and then hit enter, HOLD vol down until the phone boots into fastboot mode again. This basically tricks the phone to boot into Fastboot mode instead of erase mode. To make sure the phone doesn't boot into erase mode on the next boot you need to do the following:
6 - While in fastboot mode type this into the CLI/terminal/PowerShell window but do NOT hit enter :
Code:
fastboot reboot
when you are ready to execute the command, start pressing only vol down button and then hit enter, HOLD vol down until the phone boots into fastboot mode again.
7 - Now you are ready to boot into your system. Either boot by holding power button or typing
Code:
fastboot reboot
into the terminal and hitting enter.
By rebooting twice, you make sure the phone doesn't boot into erase mode. If you flash the stock ROM beforehand and setup your device (login to Play Store), your device will still be Play Store certified by this method. But if you unlock the bootloader and the phone erases its storage, you won't be able to download apps like Netflix, because your device will not be certified by Play Store, this is because the Play Store checks for unlocked bootloaders. But by making it check the certification while it's locked and then unlocking the bootloader, you can make this issue go away. Feel free to ask for more proper guides for dummies, if you need. I have bricked my device many times and learnt by trial and error, so I'd be happy to make you avoid those same mistakes. Cheers.

No need double reboot

It is not necessary, but a preventative measure. I've had instances where I hadn't rebooted twice and the phone booted into erase mode. This is a guide for people who want to make sure they won't lose data.

Another tip:
If you're with stock everything and don't want to loose data, do not boot into recovery mode (power + vol+) as it sometimes try to wipe data without any confirmation. Did happened here once, back in March 2019, but thankfully my pictures and most data are stored in MicroSD card.

Can confirm, if your bootloader is unlocked and you don't have TWRP installed, booting into recovery mode will wipe the device.

It shouldn't ask you to unlock phone or not in fastboot mode, as what I did unlocked mine for months ago. It should return you to fastboot mode in a flash (a fraction of seconds) and manually restart your phone by holding up power button until you'll see unlocked warning and AndroidOne logo.
If it is, try to select "unlock", but your data may wipe afterwards.

You have another device. This is for Mi A2 Lite, not Mi A2. And on top of that, it works for Android Pie. I don't know for stock Android 10 since we (Mi A2 Lite users) don't have it yet (as of my writing).

You can unlock with the same method. But I believe you will flash a zip from TWRP to fix SIM cards and that will break your phone if you lock the bootloader. So after fixing the SIM cards, you need to leave the phone unlocked, otherwise phone will be bricked. If you want to get rid of the ugly splash screen, you can flash a custom splash you can find in the forum.

You can leave it as is, but don't ever boot into recovery if you value your data from Internal Storage or if haven't backed up data to MicroSD.

[GUIDE] [TA-1032] How to unlock bootloader, install TWRP and Magisk

Code:
TRY THIS AT YOUR OWN RISK! This could brick your phone. It shouldn't but it can. If you brick your phone, or anything stops working on your phone, YOU are responsible.
Reboot combinations:
Fastboot: Shutdown and with USB cable hold power and volume down until it says FASTBOOT MODE at the bottom
Recovery: Shutdown and with USB cable hold power and volume down until the
Code:
Please release key to power off *
dissapears.
Unlocking Bootloader
Code:
Note: This will delete all user data! Backup all your data before doing this!
This part of the guide is part of the tutorial made by @Arin59 at https://forum.xda-developers.com/nokia-3/how-to/method-to-unlock-bootloader-nokia-3-pie-t4012285
First of all convert your serial number (should look like NE1*************) to MD5 Hash and enable OEM Unlock in developer options.
Then reboot to fastboot and type
Code:
fastboot oem key {HASH}
then type
Code:
fastboot flashing unlock
.
To reboot to Android, run fastboot reboot.
Installing TWRP
Code:
This will delete your user data, but it should be already deleted.
You can use any TWRP image made for this device but I had the most success with https://forum.xda-developers.com/nokia-3/development/twrp-teamwin-recovery-nokia-3-t3762512 .
Flash your TWRP Image chosen with
Code:
fastboot flash recovery your-recovery-image.img
and then reboot to recovery.
In TWRP go to Wipe and then Format Data and type yes.
Install Magisk
Install Magisk normally.

< waiting for device >
I put the phone in fastboot mode and ran fastboot with the oem key md5 hash command but it just said "< waiting for device >". I think it might be because I forgot to install the Nokia 3 USB drivers. I'm using a linux computer, do I need to find OS specific drivers?
edit: And now my phone is stuck in fastboot mode and for some reason will not shutdown no matter how long I hold down the power button for.

If you're using a linux computer, you should try running the command with sudo.
If it doesn't work, try with another cable (or computer if it doesn't work) and try again.

Thanks. I've since got it working. For some reason I had to use the -i argument (the interface argument) along with the code for the device (0x2e04) "fastboot -i 0x2e04 <command>".
However, I've recently bypassed the "NO COMMAND" screen and gained access to TWRP custom recovery but in trying to shut down the phone, it shuts down fine but only boots up in fastboot mode. Even using the fastboot reboot command from adb tools boots it up in fastboot mode. This is a problem as I need to boot it in its normal mode so I can download the magisk.zip file required for installing magisk but I seem to be unable to do so.

Thanks, it worked.
Though I tried wiping, but it didn't solve the booting issue. Unsure how to proceed at this point. I feel like I've tried everything. Actually, I just checked my /boot folder and it's empty...is that why it's always booting into fastboot?
I tried using adb to sideload the magisk.zip file but then the phone rebooted into stock recovery??
Any and all guides on this say to download the magisk.apk either into the SD card or internal storage, but I don't have a micro SD card and I can't access the normal mode of the phone to download anything.
What can I do?

I've flashed TWRP successfully but forgot to download the magisk.apk. Now whenever I boot up my phone, it boots into stock recovery mode automatically, even if I tell TWRP to reboot into system it reboots into Stock Android recovery. I can still access TWRP by holding down the up + power buttons on boot though, but I can't access the normal mode of the phone anymore.
I tried using TWRP's sideload feature with ADB tools to sideload Magisk.zip and it said it succeeded but in using TWRP's install feature to find the zip file, it wasn't in /sideload/ or /storage/ as both were empty.
How can I temporarily restore normal functionality so I can simply download the Magisk manager.apk?
