[Moto G6 Plus] 3: How to install Root (aka Magisk) - Moto G6 Plus Guides, News, & Discussion

THIS GUIDE IS FOR THE MOTO G6 PLUS ONLY
3: Root (aka Magisk)
What is Root? The easiest way to explain it is that root gives you elevated permissions allowing you to modify system files that are not possible to be modified with out elevated permissions. This process requires you to use a PC and assumes you are running the stock firmware.
READ FIRST
Before we proceed you need to download some files on your PC.
*ADB and Fastboot Installer for Windows - (Download) - When prompted to install a driver type the number 0 and hit enter. This will install the latest version of adb and fastboot where it is system-wide. This eliminates the need for adb.exe or fastboot.exe to be in the same folder as the files you will be working with. NOTE: Windows will flag this as a virus! The installer is open source and made by a Moderator here on XDA. It is a False Positive. You can view a VirusTotal report (https://www.virustotal.com/en/file/25dc5dca2494d1b1d93832b37ba9852b4f076bba86cf5029b4c944a28a1a01a1/analysis/]HERE[/url]). 26 out of 67 virus scanners report it as a virus. If your Anti-Virus is one of the ones that flag it as a virus, I would suggest you explore other Anti-Virus software, but that’s not what this guide is about.
* TWRP - (Download) - This is a modified Recovery Software allowing you to flash files that will allow you to fipe your device and install custom roms and other various things. Thanks to XDA Member @khode_Erfan who has ported it to our device.
*Magisk - (Download) - Download the Stable version here. While not required, I do suggest you download the Latest Uninstaller and Latest Magisk Manager as well.
With ADB, Fastboot, and TWRP and Magisk on your pc get ready to root your device!
On your Phone
3A: Enable developer settings by going to Settings->System->About->Tap "Build Number" 5-7 times. You will see notification at the bottom of the screen stating that Developer Options have been Enabled.
3B: Tap the back button to go back to the System screen.
3C: Now tap on Developer Options.
3D: Find the setting that says "Android Debugging" and tap on it to enable adb to work on your device. You should get a prompt on your phone about a host key. Accept it.
On your PC:
3E: Place the file Magisk-v*.zip (*=version number, so for example version 17.1 would be Magisk-v17.1.zip) on your SD Card.
3F: Use Windows Explorer to navigate to the place you downloaded the file twrp-3.2.1-37-evert.img
3G: Hold the Shift Key on your Keyboard. While holding Shift, Right Click in the window(not on the file). Depending on your windows version you should see either "Open PowerShell Window here" or "Open Command Window here." Select which ever one applies.
3H: Now type, or copy and paste, the following commands one at a time and press enter to execute it:
Code:
adb reboot bootloader
fastboot boot twrp-3.2.3-42-evert.img
3I: In TWRP, first tap Backup -> Select Storage -> Micro SD Card - > OK
3J: You will see a section that says "Select Partitions to Backup." Make sure to select all of these boxes.
3K: At the bottom of the screen Swipe the Blue Button where it says Swipe to Backup.
3L: When this is done, tap the Home button.
3M: Tap "Install."
3N: Now tap on "Select Storage"
3O: Tap Micro SD Card
3P: Tap OK
3Q: Navigate to the location of the Magisk.zip file you placed on you sd card earlier and tap on it.
3R: At the bottom of the screen use the "Swipe to confirm Flash" function to flash Magisk.
3S: When it's done tap the button that says Reboot System at the bottom right corner of the screen.
If your device reboots to android, then you have done everything right! If not here are some possible fixes. Make sure the phone is in the bootloader and connected to the PC.
Troubleshooting:
If you are stuck in a bootloop something went wrong but we can fix it pretty easy. Magisk modifies your boot partition when it is flashed. Flashing the boot.img file from the stock firmware should fix this:
boot.img: (Download)
MD5: bd305bc3bc8c591ee7ebba8f5026bb06
Use the command:
Code:
fastboot flash boot boot.img
If you you have an error such as "Can't Load Android System" or "Startup Failed" your partition table is probably corrupt. You can try fixing it by flashing gpt.bin from the stock firmware.
gpt.bin: (Download)
MD5: 631af2ecab87fe627ab00e61b07ac964
Code:
fastboot flash gpt.bin

At the moment of writing, the Magisk link directs also to twrp download. Fixed.

I have a problem with the G6 Plus Dual sim model XT 1926-7 (bootloader unlocked).
When I type the command "fastboot boot twrp.img" (so I called the file) it tells me in CMD:
Fastboot: Unknown error: downloading 'boot.img' ... OKAY [0.555s] booting ... FAILED (remote: unknown command) finished. Total time: 0.569s
I tried to reinstall the drivers, changed "minimal adb" to "platform tools" and remains the same.
Any idea how to fix it?

Try using different usb cable and different usb slot (usb 2.0 is better for fastboot).

I have not tried with another cable or another port, just with another pc, the weird thing is that I have unlocked the bootloader without problem, but I can not start TWRP.

OTA updates for unlocked, rooted Moto G6 Plus
My Moto G6 Plus is unlocked and rooted after following this guide. Today I got a notification of an update from Motorola, but the OTA update fails. Is there a way to get this update?
Relative newbie so excuse me if answer is obvious.

Well, you cannot do OTA directly on a rooted device. You have basically two options:
1) unroot, lock bootloader, take OTA, unlock bootloader, root.
2) find images of this new update, flash them, profit.
x) take my advice with a grain of salt. that's how it used to be on older devices, I haven't tried it myself. Research, research, research before you actually try any of this.

Thanks for that information. As it seems to be a relatively minor update (OPWS27.113-89-2 to OPWS27.113-89-5) I think I will wait for now.

I am running stock ROM unrooted and updated to 9.0, will this still work?

Do you have problems with sim signals, IMEI or something when unlocked the BL?

Managed to boot into TWRP but when backing up I get error 255. I have attached the twrp log file.

Decryption is broken in TWRP, therefore TWRP back ups are useless. Use Titanium Backup or Migrate.

I had the same problem. Fixed itself when I went onto a new (my old) laptop. I guess it's something to do with drivers.

In TWRP do I really need to back up every single partition I have or just the ones that get changed by Magisk? They won't all fit on the sd card I currently have, but one or two will fit.

No. Backup efs and the rest you don't need to worry about. Besides, it's pointless to backup data right now. We can't decrypt data in twrp so the restore will always fail on restore or boot up.

[Q] No android-info.txt & android-product.txt ~I Need Help~

Hey everyone,
This is my first time posting to the forums. I have been trying to get everything done without having to ask questions since there are so many all over the place and I can see how it can get tiring trying to help everyone when their may be an answer out there already if you look. However, I have ran into an issue that I can't seem to find much information on. I have the HTC Rezound that is S-On (apparently you need a Linux machine to get S-Off which I don't have. Using Windows 7.) and have been using fastboot to get things done. I have unlocked the bootloader and have installed the 'Amon Ra' recovery and setup Superuser and SU. As far as I know, I have to use ROM's that are S-On friendly (right?) and I chose to try out 'EclipticRez' and later 'Talon'.
As I tried to flash the ROM's through fastboot it fails with the following errors every time and I cannot continue:
archive does not contain android-info.txt
archive does not contain android-product.txt
From what I found is that it may be a bad download of the ROM. Maybe.... But it happened consecutively with two different ROM downloads.
I also read that maybe the recovery wasn't setup, which as far as I know it is. Should I use a different recovery? Everyone usually references to using CWM, which I wouldn't mind using but I couldn't figure out how to get SU access.
Can I just create the files myself? They are only txt files after all.
If anyone can help me with this I will be so grateful! I'm pretty new to this and it has definitely been a fun learning experience for me
Much thanks in advance!

1) Switch to TWRP or CWM for your recovery.
2) You install the rom zip via recovery.
3) You then need to fastboot flash the kernel from the rom zip you downloaded. You don't install the whole rom via fastboot.
To borrow from the CM11 thread.
- Place the boot.img into the platform-tools folder of the Android SDK's install directory.
- Boot to the bootloader.
- Ensure your device is connected to your computer and that your device is now in fastboot mode. This is a white screen and it says fastboot on it.
- Open a Terminal (OSX or Linux) or CMD window (Windows) and cd to the platform-tools directory of the Android SDK's install directory.
- Issue this command to flash the boot.img we placed in the platform-tools folder earlier:
Code:
fastboot flash boot boot.img
- Watch the output of the terminal, it should say something like "sent successfully".
- Finally send this command:
Code:
fastboot reboot
Since you're s-on, you'll need to do this whenever you install a new rom. Using these steps, you can install any rom you want.

also to note....you dont have to install linux to get s-off....if you follow my guide you can do it straight from a live disk rather than installing it....so it wont erase or mess up your windows partition at all
Solved!
Thank you, Mjones, I finally got it! I knew it was much easier than I was making it out to be. I was missing the kernel! Yeah, a crucial part in the process, I know
I first ran CWM and flashed the ROM over and ran the .zip through recovery (which I couldn't understand at first as I could never find it in the directory) but the installer would only go 50% and would fail... makes sense why now lol
I later flashed TWRP and backed up again after recovering from the fail. I flashed over the kernel and voila! So simple... Had to slap myself.
Thanks again! Case solved.
REV3NT3CH, that is sweet!! I have been hoping there is a way to gain s-off with Windows. I have 7 at work and 8.1 (which I can't get anything to work on) at home. I actually have to focus on work today haha so I'll look into the method and try it out tomorrow if I can. Thanks for all of the help.

I need to be able to do it via fastboot, as my Motorola Electrify M is stuck in a bootloop and there's no way I could find to boot into recovery. I'm using ./fastboot update name_of_update.zip and it is an official OTA .zip but I still get this error. Any suggestions?

Did you try this first? (Right from Moto's site)
Perform a factory reset using external keys
1. Power off the phone, press and hold volume down button, press power button
2. Screen will come up with "Fastboot", press Vol down key to cycle through choices until you get "Android Recovery", then press Vol up key
3. Wait for the "triangle ! / Android" screen then go on to step 4
4. Press both Vol up and Vol down key simultaneously. A menu will come up
5. Tap on Vol down key until "wipe data/factory reset" is highlighted, and tap Power key. Another Confirmation screen will come. Tap on Vol down key until coming to Yes and tap Power key
6. After userdata is cleared, the "reboot system now" option will be highlighted by Default. Tap Power key
7. Phone will reboot to initial setup screen.

I have same problem on asus zenfone max pro m1 I bought it online said used and now working
can't boot into recovery.
can't boot into system.
Only EDL Mode and Fastboot Mode, but fastboot is Locked whic I cant unlock because I cannot boot into system to toggle USB Debugging and allow OEM unlocking
Qualcomm is harder to flash than MTK that can use SP FlashTool.
on this I use QFIL but keeps "sahara error". I tried searching and try moving firmware file to bin but no Luck. I'm currently trying different version of QFIL Tool.
If it FAILS my only HOPE is to use MUT-QCfire which will Require a "SmartCardReader" Which is a bit pricey and I don't even know if it will work on my device.

Need help installing recovery on XT1526, it's just not working, tried all the methods

EDIT: ALSO, use usb 2.0 ports to flash stuff, usb 3.0 is not working 100 percent yet.
EDIT, 14 Mar 2016: Kingroot got me to root and now I have twrp installed, http://www.kingroot.net/ .
I have a Sprint prepaid Moto E 2015 LTE, XT1526. I did the motorola bootloader unlock, that went fine.
The phone works and is activated on RingPlus, when it boots, I get the Red Warning, Bootloader unlocked, when normally booting.
When I try to flash a recovery to the phone (all that I could find here on XDA), I get this response:
S:\Phones\Moto_E-2015-2ndGen-XT1526\adb-and-fastboot>fastboot devices
TA0XXXXXXX fastboot (edited to take out SN)

finished. total time: 0.015s
S:\Phones\Moto_E-2015-2ndGen-XT1526\adb-and-fastboot>adb kill-server
I've tried everything, and am providing as much info as I can, in case anyone seeing something that is 'new' or 'different' about my phone.
Double check and be sure you're attempting to flash the TWRP for the Moto E 2015 LTE "Surnia", not "Otus" (which is the Moto E 2015 3G). iirc, I used Squid's TWRP from here: http://forum.xda-developers.com/moto-e-2015/development/twrp-squid-twrp-recovery-moto-e-lte-t3137649 . If 3.0.0 doesn't work, try 2.8.7.
You should also try changing USB ports. I ran into a similar issue where I wasn't able to flash things when I plug into my most often used USB port. I suspect that the contacts got worn from how often I used it, so I tried another USB port and it worked fine.
I have done same procedure as yours and meet same problem yesterday.
I flashed twrp recovery with following command,
fastboot boot recovery.img
instead of
fastboot flash recovery recovery.img
here are the post which I followed.

I know that, does not help. I've tried that recovery, one from cyanogenmod also, the recovery img is not the problem. Thanks anyway.
go to phone options and turn on USB debugging and when you go to flash it..
- turn off phone.
- hold volume down and power to get to boot loader screen..
Leave it there and connect to PC.
It should be showing you the bootloader screen.. you know what that is right ?
Then open "Minimal ADB and Fastboot" install folder..
Right click empty folder space while holding shift key down..
Select open cmd window here..
type in either,
fastboot devices
or
mfastboot devices
and make sure it says your device is listed
then paste into cmd window..
mfastboot flash recovery recovery.img
make sure your new recovery file has that name and is copied to that fastboot folder.
that should be it..

Can a DEV please help ? If I need to go back to stock I'll be glad to do it and then unlock the bootloader again, however, I've posted in two diff forums trying to get someone to tell me the correct SPRINT img to bring back to stock, no answers.
XT1526_SURNIA_USC_5.0.2_LXI22.50-29.1_cid9_subsidy-DEFAULT_CFC.xml
XT1526_SURNIA_REPW_5.0.2_LXI22.50-56-1.1_cid6_subsidy-REPUB_CFC.xml
XT1526_SURNIA_BOOST_5.0.2_LXI22.50-14.8_cid9_subsidy-DEFAULT_CFC.xml
I think it's the boost, but it doesn't have the SPRINT label on it, like my phone.
You just said,
"Can a DEV please help ? If I need to go back to stock I'll be glad to do it and then unlock the bootloader again"
So why would you say that ?
Did you relock your bootloader ?
Maybe that is why you are having a problem ?
I never have relocked mine eh..
And i have had no problem flashing TWRP from Squid.. all his various updates overwriting the old one.
I have flashed a bunch of stock retail recoveries too and all of those worked fine too.
I am curious did you try and load recovery after to see if it actually changed or not ?
EDIT:
Can i ask you exactly what Custom Recovery you are trying to install ?
And did you verify the MD5 hash ?
I always do *if it's available..

I've done all those things and tried to post as much info in my OP. Is there a Dev that can help me?
I've now tried to go back to stock in an effort to unlock this biatch using XT1526_SURNIA_BOOST_5.0.2_LXI22.50-14.8_cid9_subsidy-DEFAULT_CFC.xml, and it wont let me do that either. It's not letting me write to the GPT partition. This leads me to believe my phone is NOT unlocked, even though the bootloader shows UNLOCKED BOOTLOADER. Anyone know an answer?
I noticed something a while back when I attempted to flash recovery on a different phone (nexus 6) but failed. I tried a bunch of stuff to no avail. The solution was to simply get a new set of platform tools because mine was too old. Doesn't hurt to try.

Thank you for trying. I just found a post, (and now I can't find it), but the guy went through what I did, and then he used KingRoot, http://www.kingroot.net/ , and it worked.
So, I tried it too, and magic, it worked. I now have root and TWRP installed.
I could have sworn I tried KingRoot, but it must have been on another phone I had.
Are you sure your recovery file is called recovery.img and not twrp.xxx.img? If not you need to rename it
Another problem I had, I was using a USB 3.0 port on my computer. This is a not the way. Using a USB 2.0 port works on flashing stuff.
Hi faheyd, I also have XT1526 on android 5.0.2, but kingroot fails. I was told not to update OS to keep it working in India.
Doess ur phone run on 5.1?
Does USB debugging needs to be activated?

Complete Guide to Unlocking, Installing TWRP, and LineageOS w/ Root on A2017U

Quick notes:
ALL files/software needed are linked below
Process only confirmed working for this model, A2017U
Desktop PC used is on Windows 10 x64, no 3rd Party Antivirus
I assume you have ADB installed on your computer, but if not here is an easy guide:
https://forum.xda-developers.com/showthread.php?p=48915118#post48915118
Also assumed you have the Axon7 connected to PC via USB cable
Here's the steps I took, with info compiled and reorganized from the two guides linked at bottom of post:
1. The downgrade from B15 Nougat to B29 Marshmallow
(skip to step 2 if you are already on B29)​
A- Download the full B29 software package, provided by ZTE on their website. Select the support tab halfway down the page, then select the software updates to download the .ZIP (mirror provided at bottom in case ZTE changes things)
B- Download it, unzip it once, then put the update.zip file on your SD card.
C- Turn on OEM unlocking in the Axon Settings Menu (it is needed to flash from sd card)
You can do this by navigating to Settings -> About phone -> Tap "Build number" 7 times.
Now navigate to Settings -> Advanced settings -> Developer options -> Enable "OEM unlocking".
D- Boot phone to recovery - [Power] + [Volume Up] key combo - Release the keys when you see the ZTE logo.
E- Choose update from sd card, then pick the update.zip from the sdcard
F- The phone will flash the B29 software. It is a bit slow, have patience and let it do what it needs to do.
2. Unlocking Bootloader and installing TWRP​
A- Install the Qualcomm QUSB_BULK drivers. You should be able to simply extract them, then right click qcser.inf and press Install.
B- Boot the Axon7 into EDL mode. [Power] + [Volume Up] + [Volume Down]
C- Your device should be recognized in Windows’ Device Manager as a COM port called "Qualcomm HS-USB QDLoader 9008".
D- Download and Unzip the FASTBOOT_UNLOCK EDL file.
E- Install MiFlash on your computer. Open the program.
F- In MiFlash, Select the folder "A2017U_FASTBOOT_UNLOCK_EDL". Use the child folder inside containing fastboot.img and other files. Do not use the parent folder containing the META-INF folder, it caused flashing to fail for me.
G- Now just hit [flash] - watch the progress bars move and wait for the device row to turn green with flash complete!
H- Use [Power] + [Volume Up] key combo to exit EDL mode and enter recovery
I- Open CMD window as admin, and use "fastboot oem unlock" command to unlock (and wipe) your device. When prompted on Axon7, select Yes to unlock bootloader
J- Reboot phone into EDL mode
K- Return to MiFlash, Select the folder "A2017U_B29_TWRP_EDL". Click [refresh] if device row shows anything under status.
L- Now just hit [flash] like before - watch the progress bars move and wait for the device row to turn green with flash complete!
M-Reboot phone to TWRP
If the flash fails or is unable to communicate with the device, use the [Power] + [Volume Up] + [Volume Down] key combo to restart EDL mode.
Release the keys after 5 seconds then wait another 5 seconds before using the [refresh] or [flash] buttons on MiFlash.
3. Installing Lineage OS With Root​
A- Using TWRP, Wipe the device (data/cache/dalvik, all that stuff)
B- Install the Universal Bootloader (A2017X_B15_Universal_Bootloader.zip), and modem (A2017U_N_Modem.zip)
C- Install Lineage OS ROM .zip, with root addon (addonsu-arm64-signed.zip)
D- Install Gapps
E- Restart Axon7, enjoy!
Thanks to the reply made by u/tabletalker7 on my last thread, I now have an unlocked bootloader, TWRP, and LineageOS with root. 10/10 !

Downgrading is not necessary.
Downgrading step is not necessary, upgrading Bootloader and modem neither.
So, is the bootloader unlockable on Nougat? Could someone link me to a guide?

B- Read from post #1
I am getting an error when I try to flash FASTBOOT_UNLOCK EDL with MiFlash. Error is "can not found file flash_all_except_storage.bat". Anyone else seeing this?

The fewer steps the better, of course.
So if we are on B15, we can just skip section 1 of the guide, and the rest of the steps will work without the downgrade to B29?
Excited to try this, since I've used CM ever since it was the cat's pajamas on the HTC G1/Dream but haven't even rooted the Axon 7 yet.

Going back to stock is easy peasy.
use the official update from ZTE, place update.zip on sdcard
boot to recovery and wipe (cache/data/system) then flash update.zip
reboot and you're back to stock
want to lock the bootloader too?
boot to fastboot
fastboot oem lock

Thanks!
I can flash the fastbook unlock in MiFlash, but I get stuck trying to actually unlock the bootloader afterwards. ADB recognizes the device when it's turned on, but when it's in recovery, it doesn't recognize it at all. So I am lost as to what to do.
Edit: Alright, I got it to work. I just went into bootloader and unlocked instead of recovery. Maybe I misread the instructions but all of your other instructions were spot on! Thanks
Is there any way to do this on a macbook?

The Complete Pixel 3 How-To Guide (newbie friendly!)

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.

adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll
fastboot.exe
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 wrote it like that because the file isn't actually called "boot.img", but rather "bootloader-blueline-blahblahblah.img" where "blahblahblah" is the release. Since it changes, I figured just calling it the "bootloader IMG" would make more sense.

Was my misunderstanding. I thought you were implying people should go back to stock recovery to flash ota. You are talking about flashing ota in twrp. You might clear that up a little bit in that section.
Great post.
Unfortunately, if you are writing a process, then writing everything out is a requirement. Especially with item numbers or using an outline format. Not everyone understands shortcuts taken or abbreviated words, unless they are spelled out in the beginning. IMO, wrote and read too many processes. Including software requirement documentation.
Hi,
thanks for the thread :good:

Yes, I think so too.

I wrote it like that because the file isn't actually called "boot.img", but rather "bootloader-blueline-blahblahblah.img" where "blahblahblah" is the release. Since it changes, I figured just calling it the "bootloader IMG" would make more sense.

The boot.img is into "image.zip"
Then I suggest to flash into a and b (or both)
Code:
fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
or
fastboot flash boot --slot all boot.img
Edit
be careful here: Factory reset via ADB sideload (can also do this without wiping data)
bootloader is bootloader, boot is boot, bootloader.img isn't boot.img
so, maybe better to write:
fastboot flash bootloader nameofbootloader.img or if simply renamed fastboot flash bootloader bootloader.img
deleted, bug.
trouble flashing files
When I try to flash twrp.img or boot.img this is what I get back " FAILED (Write to device failed in Send Buffer() (Too many links)) fastboot: error: Command failed.
Any thoughts?

Please read the instructions carefully. You cannot flash twrp directly. "fastboot boot twrp.img" then when twrp boots you can use it or make it permanent by flashing the install zip or the internal twrp option. I go with the install zip as it seems more stable to me (placebo I suppose).

Turns out it was the cable, it is an expensive one from Amazon so not sure what I should be purchasing for next time.

Are you able to get into recovery? If so, download the full ota to your pc and side load it with adb.

boot to the twrp.img and flash the twrp.zip, unless you are on android 10 you should have no problem unless you are doing it wrong. not exactly hard to do.

There are a few suggestions at https://www.theandroidsoul.com/how-to-fix-oem-unlock-greyed-out-or-oem-unlock-disabled-problem/
However, if the network carrier has locked the bootloader, you cannot unlock it. In the U.S., Verizon and AT&T phones generally cannot be unlocked due to locked bootloaders.

tried to flash firmware, cant do anything now

Hi all,
The story is that I had Linage flashed, but it said it was time to update the firmware, so I tried to do that.
I booted in twrp and flashed the most recent firmware. I had plenty of power on the battery. But after it finished it booted into a classic miui interface. From here it only got worse. It asked for my password which I entered several times, but it was incorrect.
What I tried was to clear the storage. But I get the same error when it boots - it boots into miui, then shortly after a google load screen and then it reboots.
I tried downloading the mi flash tool. But when I connect the phone and locate the file, the screen has just one line in the corner saying something like "press any key to reboot".
With the adb command it doesn't seem like there is actually made a connection.
I do not really care which OS you suggest I install, as long as it at least can get it up and running again.
------------------
I just got it into fastboot and it goes fine with fastboot devices where I can see that it is connected, but when I enter fastboot flash recovery twrp.img then the phone reboots with an error code in the cmd window saying:
"FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed"
Any suggestions to what I can do? Can it be the twrp image that is causing the issue?
twrp-3.3.0-0-beryllium.img 30.3mb

This will work with any Android 10 custom ROM
If you want to stay unencrypted, you have to use dfe (disable force encryption). I have never used it, but if you want it try to get one without magisk.
1. 11.0.6 is the latest firmware. You can download it from here:https://xiaomifirmwareupdater.com/firmware/beryllium/
2. You have to format your internal storage.
3. Steps: go to recovery (press back when it asks for password)->wipe->format data (it will ask you to type "yes")-> wipe system, data, internal storage,cache, davlik cache
Copy firmware,rom, gapps, dfe into your internal storage, flash firmware (most ROMs include vendor but flash full firmware just to be sure), ROM, gapps, dfe and reboot.

Twrp!
You flash firmware as a normal zip.
I understand that twrp works for you.
If it doesn't, flash twrp through fastboot and then proceed as i mention above
Thanks for your replies.
The problem I have is that fastboot does not really seem to work.
When I try to do a fastboot command I get the error that goes:
"Sending 'recovery' (31068 KB) FAILED (Write todevice failed (Unknown error))
fastboot:error: Command failed"
Also, I just tried the Mi unlock tool and it seems that it cannot create a connection with the usb cable - so could that be the reason that I cannot flash it?

Download twrp for poco f1 from the official twrp site.
When everything is ready and you have pressed flash, THEN boot into fastboot and connect the cable
Edit: you also might have relocked your bootloader. If what I mention above doesn't work, unlock your bootloader again with the unlock file Xiaomi originally sent you.

The phone doesn't boot into a system, and currently as I load fastboot whenever the connection to the computer is made it goes to a screen saying 'press any key to turn off'.
I did notice, though, that after I from recovery wipe all data, then in the first boot it encrypts the phone. But it never manages to get the OS up and running.

HI mate,
I wanna check how long did it take to install Android 10 on your poco?
Cuz I installed the rom for more than 30 minutes after reboot and it is not over by follow your steps.
Idk what's the problem with my poco.
------------------------------------------------------------
New update:
Finally, I completed flash the rom, and Idk what's the problem, lol
I can boot into both fastboot and recovery. The recovery is Mi-recovery 3.0. Though, in recovery it doesn't seem that I can get any connection with it.
-----------
update
Currently, when I do anything beyond fastboot devices I get the screen reading "press any key to shutdown"

You most likely had your bootloader re-locked. You have to unlock it again
sorry for the late reply.
I downloaded MiFlashPro, and apparently I could flash miui 11. So far, so good. But as I tried to flash or even boot into twrp I got the same command as I used to.
Can the issue be because I maybe don't have the latest drivers installed?

Do you have all the drivers installed on your pc ?
ADB and Fasboot drivers. And try using usb 2.0 ports. Mi tools have issues with usb 3.0 ports. And You should be on an Intel processor. You can also try twrp 3.3.1 beta by @Reignz.
