[Root] Zenfone 2 Official Android 6.0 Root + Xposed and Downgrade

**WARNING** You need to have background knowledge of adb, fastboot, twrp, sideload.. before you can go on with this thread.
1. All credits go to @shakalaca. If you like his work, please make him a small donation for encouragement.
2. This is a systemless root. Yet you need to unlook Lollipop before upgrading to Marshmallow.
3. Flashing the attached SuperSU file modifies stock boot.img. In case you receive an OTA file later, do
**REMEMBER to FLASH BACK TO STOCK Android 6.0 BOOT.IMG** to unroot before upgrading to official Android 6.0.
Root:
1. Unlock your device in Lollipop, then upgrade to Android 6.0
2. Once you are in Android 6.0, fire the following command to boot twrp. <twrp.img> is the twrp recovery file. This TWRP is recommended.
HTML:
adb reboot-bootloader
fastboot boot <twrp.img>
3. adb sideload the attached SuperSu file in twrp. /OR install the SuperSU in twrp if you saved it in device storage.
4. reboot system. You will see a warning screen saying "Your device has failed Verification". Ignored it and wait for the reboot.
5. Done
Unroot:
Just flash back stock boot.img
Xposed:
1.Flash the attached Xposed file from twrp.
2.use Material Design Xposed Installer: Download Xposed Installer here
Downgrade to Lollipop:
In case you need to downgrade to Lollipop, follow the instructions with care. Do it at your risk.
Refer to Asus Zentalk Forum and grab the required files from there.
HTML:
fastboot flash token bom-token.bin
fastboot flash ifwi ifwi_ann_a0-mofd_v1-ze551ml.bin
fastboot flash fastboot droidboot.img
fastboot flash splashscreen splashscreen_ze551ml.img
fastboot reboot-bootloader
Now you are back in Lollipop. You can flash back stock recovery(.184 recommended), wipe the device(cache/userdata/system) and then sideload back stock LP or MM as you wish. OR, you can flash custom recovery/boot/system.img start from here.
Good luck!

It worked!Thank you master!I bow now....

I just need root on 6.0.1. Is this going to achieve that?

It does work, but YMMV, my phone is one of the few that works completely with the beta software. But before running fastboot cmd in adb. Use adb reboot recovery, then fastboot cmd. Phone will reboot twice after sideload of SU.

Assuming that everyone knows how to use adb and its commands
1: Well first make sure adb and drivers are on your pc.
2: Plug phone in make sure USB debugging is on
3: In adb cmd window type "adb devices" to make sure phone is recognized, if so proceed
4: type "adb reboot recovery" phone should boot into recovery with android robot on screen
5: Then type "fastboot boot <twrp.img>" twrp.img is whatever your file is named
6: phone will boot into recovery, go to adb sideload in recovery
7: type "adb sideload <SU.zip>" or whatever you have it named
8: After it's done loading reboot from recovery, it will reboot twice and the screen will say as per OP
9: After phone optimizes...enjoy root.
This is for advanced users

He's using whats called "tethered TWRP". It's basically running twrp on your phone from your computer instead of actually installing it (which would require unlocking).

Thank You for explaining that to me, appreciated!

To downgrade to Lollipop, is it possible to just use AsusFlashToolInstaller and flash raw firmware? Any harms by doing that?
Thank you in advance.

You need to adb sideload all LP .184 images first then use Asus FlashTool to flash RAW Firmware.

Maybe I'm doing something wrong but my phone isn't recognised when trying to flash twrp from the dead bot before recovery? Just says waiting for device. Already checked device manager as well

Guess your ZF2 is not unlocked in LP first, so that you can't see twrp booting. Since you are in Android 6.0 now, try to downgrade to LP, Unlock it, upgrade to 6.0 and then root.

[Root] Using Tethered TWRP to root Android 6.0.1 ZE551ML with locked bootloader

**** This is a modified post with detailed explanation and different files. The original post was made by @samcjtasi at here. *****
If you installed Android 6 from locked Lollipop Bootloader or forgot to unlock the bootloader before the installation and all you need is to root the device, this is a guide for you.
I did unlocked my Bootloader when I was on 168 with Asus unlock app. I flashed 194 raw file via Asus Flash tool which locked my bootloader. I installed MM via adb sideload and I had MM with Locked bootloader. I used this method to root my phone.
I am sure you'd already known that rooting the phone (acquiring the administrative rights for your own phone) will void the phone warranty.
With this method,
1. You do not need to downgrade your MM bootloader to Lollipop, unlock it, install twrp and root the phone, and then upgrade back to MM.
2. You do not need to install the TWRP. You will be running the TWRP from the tethered mode so your stock recovery will be intact.
3. SuperSu initial installation will modify some files in your boot partition in order to re-direct the system request to the SuperSu, as such In case you want to receive an OTA file later, do
**REMEMBER to FLASH BACK TO STOCK Android 6.0 BOOT.IMG** to unroot before upgrading to official Android 6.0.
4. Make sure your phone has battery 80% or more.
Requirements:
1. USB drivers for Asus have to be installed in the computer and your computer should recognize and can do the file transfers between the computer and your phone. You can get the drivers here. You will need to allow the file transfer from your phone when prompt.
2. Android debug bridge (ADB) has to be installed in your computer. I used ADB version 1.0.32. Some knowledge in using DOS and ADB is a plus.
3. Your phone should have the developer option enable and usb debugging should be checked in the developer option tab.
4. You need to know how to use the TWRP. There are a couple videos on youtube explaining about using TWRP.
The Files you need for the root.
1. TWRP - you can download the latest twrp file from here. The latest is ver 3.0.20. You could use older 2.8 versions if you want it.
2. SuperSu installer - I did try with latest SuperSu without success as such use the SuperSu patched by @shakalaca . Get the BETA-SuperSU-v2.74-2-20160519174328-patch-by-shakalaca-for-zenfone2-6.0.zip file here.
Steps:
1. Copy the downloaded TWRP to the directory that you install the ADB. (If you do not want to type long file name in adb, rename it to twrp.img. )
2. Connect your phone to the computer and copy the SuperSu installer to the phone internal memory or the external SD card.
3. Open the command prompt windows with administrative rights. (Without admin right ADB will not work properly).
4. Go to the ADB directory using the cd command. (e.g. cd\, cd adb, etc...)
5. Start the ADB environment by typing "adb start-server" . (without the quotation marks of course). You should see ****the demon started successfully*** message.
6. If you want to check your phone connection in adb, you can type "adb devices" to see your phone is recognized in ADB environment. You should see your phone serial no. and status .
7. Boot the phone to bootloader by typing "adb reboot-bootloader". The phone should vibrate and go into the fastboot mode. Wait till your phone get in the fastboot mode before you proceed.
8. Give the command to boot the phone to the twrp by typing "fastboot boot twrp.img". (If you did not change the name of the image file you need to type or copy and paste the whole file name).
You will see the message saying like-
"downloading 'boot.img' .....
OKAY [0.668s]
booting.....
OKAY [0.450s]
finished. total time: 1.120s "
The phone will vibrate twice and the Asus Logo with black splash screen will appear. The phone is start booting with TWRP image.
9. Unplug the phone from the computer. (If within 30 sec your phone should not start booting to TWRP. you can press and release the power button to go to the normal boot mode or press and release the volume-up key to go to the recovery mode. The TWRP should start by then.)
10. In TWRP install the SuperSu file by tapping install option. (I am sure you remember where you put the SuperSU installer zip file)
11. When the SuperSu installation is completed you will see the message saying like " You will see the your phone has failed verification message and reboot a couple times". Please remember that.
12. Clear the Dalvik cache and then reboot the phone. (You can reboot the phone without clearing the dalvik cache if you want).
Your phone will reboot and you will see the triangle saying like "your phone has failed verification" message and then automatically reboot the phone, showing up the message again. It would happen two to three times and you phone will be booted to the system. (You will not see that error message anymore in the upcoming boots).
Now your phone is rooted. You can check it by installing and running the app like root-chekcer.
Good luck.

It should not be go to stock recovery. The command is to boot with twrp.img.
Did you see message "booting ok finsihed" in the adb window?
Once you see that message, you can unplug the phone from the computer and twrp should be boot within 30 sec.

I finally found the time to update, everything went smooth but I'm having problems booting the twrp
I've tried several twrp from the guides but none worked
In cmd it says
Downloading boot.img
Okay
Booting...
Okay
Finished
C:\
The phone reboots but it goes to the dead droid screen.
I'm using adb and fastboot from adb-setup-1.4.3
IntelAndroidDriver1.10.0 and I've selected this version for the device in device manager.
The so is win 10 prof, I'm starting cmd as administrator.
I tried unplugging the phone and leaving it connected.
Also I'm using the 550 version, I've tried twrps from several threads for 550 and 551 (even tho twrp has merged both phones)
Am I missing something?
A little ot :
I need root 'couse adaway but I thought I would just use the twrp file manager to swap the default hosts file with the one I had in L.
It should work, right?

The guide was written from the experience working with 551ML but it should work for the 550ML I think.
I am also using the Win10 Prof and my adb has a date of 3/30/2015.
I downloaded the latest twrp from the teamwin site. I did not use the twrp mentioned in this forum because they did not work for me. (The purpose of this guide is to use TWRP as temporary and not to install on the phone as such we do not need the signed TWRP ).
In the original thread some mentioned about going to the stock recovery (dead droid with red triangle) as such I put the instruction to press the power button or press the volumn-up button to go to the recovery mode. Actually, they are not required. If everything works, your phone should start booting with the twrp image.

If you saw the message booting .... and ok your phone should be start booting to TWRP not the recovery. The command was to boot the phone with TWRP image. Try to download the TWRP image again from the teamwin site.

If someone just need root for Adaway, just don't, it is not required anymore since you can use other adblocker without root. Just install Block this and you're on: https://block-this.com

If you are using latest twrp directly downloaded from the teamwin site and if you are following the steps that I mentioned you should be OK. The only thing different could be the ADB version. Try different adb version or try this on the different computer.

Thanks. I got systemless root by this method.

Thanks for the reminder, I'm using this until I get twrp to boot.
I tried adb 1.0.36 that should be the latest but it didn't work. I'll try on win7 or something.
If someone that succeeded could do
Adb version
Fastboot --version
And report here I'd be grateful.
Edit:
I've tried win 7 too but without luck.

I confirm - it doesn't work. I have too "dead droid" and "No command" below.

ok, so how to install xposed framework?

Hi,
Does it reset the phone (apps, documents, accounts,...) ?
Tks !

This will probably not work. In other for it to work and be able to boot into twrp, I had to unlock the bootloader first, because the "fastboot boot twrp.zip" command wouldn't work unless I did so

No it does not. The procedure is to boot with twrp image temporarily.

It work for me though. If you unlocked your bootloader you do not need this method. You can simply install the twrp to your recovery partition.

I can confirm it does not work with a locked bootloader, it boots into the dead droid screen.

Can i install Xposed with threded recovery

Help Me Root This Thing! XT1575

I've done a lot of research on a reliable way to root my Moto X Pure Edition XT1575 and want someone to check my plan before I pursue this. I'm gonna download TWRP for Clark and superSU 2.78 and put them in the same folder and open up the command prompt in that folder. Then hook up to the PC and enter the following command "fastboot boot twrp.img" then I'm gonna replace the twrp.img with the name of the twrp file and backup to the SD. Then reboot into the bootloader again and flash twrp with fastboot "fastboot flash recovery twrp.img" then start recovery and go to reboot into recovery again to lock it in. Then I'm booting back into twrp and going to Advanced & Terminal and entering the following command "echo SYSTEMLESS=true>>/data/.superSU then back home then flash superSU 2.78.
Please correct me on everything that may be wrong. If there's a better way to root, tell me how to do it your way.

You've researched well. Couple things: The command is "echo SYSTEMLESS=true>>/data/.supersu", you added capitols on supersu. Next your first command of "fastboot boot twrp.img (or whatever you rename the TWRP recovery image to)" will live boot TWRP, which for our device is not necessary. Live booting is essentially booting into a custom recovery environment without actually installing the recovery. This is useful for devices that DO NOT have factory images available, which allows you to make a backup in the live environment prior to altering your device. We have factory images and factory recovery images, so you can skip this step and go right into "fastboot flash recovery twrp.img (or again, whatever you rename the recovery image to). Then after the recovery flash from within fastboot, you must reboot into recovery using the button select options within fastboot or your recovery will be overwritten by the stock recovery. Upon first boot of TWRP you'll have an option to keep your device read only or read/write. I personally choose NOT to keep it read only, rather read/write, because I don't care about taking OTA's with a custom recovery, but this is up to you. Then you'll want the supersu.zip on your device already (you want the regular standard current version, not a modded one from here: http://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703), either on your internal or external sd. And yes, prior to flashing supersu enter the command in TWRP without quotes "echo SYSTEMLESS=true>>/data/.supersu" (this prevents the bootloop that our device gets when flashing supersu in systemless mode). And your good to go. I just did this a few weeks ago from clean fastboot flashing the latest factory image, works perfectly.
Now for some clarity, I'd like someone else to chime in on the TWRP command "echo SYSTEMLESS=true>>/data/.supersu" that has to be entered. I know for sure entering the command prior works, and roots properly, but I have also read that the latest 2.78 version of supersu does not require this. I'd really like someone that KNOWS FOR SURE (no opinions) if this step can now be bi-passed, or if our device requires and will always require this step now and in the future. This will help solve a ton of questions about this issue that are spread throughout the forums so users don't have to dig to get a simple answer.

Thanks for taking the time to educate me on this. I'm gonna give it a try in a few minutes. Will I be a developer if I get it right? Hahaha I'll let you know how it goes

Then you'll want the supersu.zip on your device already (you want the regular standard current version, not a modded one from here: http://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703), either on your internal or external sd. And yes, prior to flashing supersu enter the command in TWRP without quotes "echo SYSTEMLESS=true>>/data/.supersu" (this prevents the bootloop that our device gets when flashing supersu in systemless mode). And your good to go. I just did this a few weeks ago from clean fastboot flashing the latest factory image, works perfectly.
Now for some clarity, I'd like someone else to chime in on the TWRP command "echo SYSTEMLESS=true>>/data/.supersu" that has to be entered. I know for sure entering the command prior works, and roots properly, but I have also read that the latest 2.78 version of supersu does not require this. I'd really like someone that KNOWS FOR SURE (no opinions) if this step can now be bi-passed, or if our device requires and will always require this step now and in the future. This will help solve a ton of questions about this issue that are spread throughout the forums so users don't have to dig to get a simple answer.

It worked! I'm rooted and looking for a stable rom with a lot of features and customizations that works with Verizon LTE. I also want viper4android. I'm glad I backed up because I tried flashing a viper4android zip and it caused my phone not to boot. It just sat at the unlocked bootloader warning so I just restored it. Evidently, I was supposed to unzip the file in esfile Explorer and install the apk. I think I also needed the selinux mode changer app.
What would I gain by installing a custom Kernel to my rooted stock rom? Can I even do that?

I literally did this to a fresh MXPE two weeks ago... misspelled the filename so it wasn't recognized (it isn't supersy apparently), and flashed SuperSU 2.78-SR1, rebooted and stuck at boot logo for 20 minutes. Rebooted into TWRP and entered the correct echo command to create the .supersu file and reboot, it looped twice quickly and then went to the lockscreen after a 2-3 minutes.

[GUIDE] Unlock/Flash/Root for the Pixel 2 XL (taimen)

Introduction
Hello everyone, this is a guide to assist you with customizing your Pixel 2 XL! I will be going over installing fastboot and adb, unlocking your bootloader, how to flash the factory images for clean flashes and upgrades, and how to root. Please feel free to ask any questions if you need clarification. Enjoy!
This information has been distilled from Google's official factory image site and the Magisk thread.
Installing fastboot and adb
Thankfully, Google has provided just adb, fastboot, and systrace as a simple zip file, making this process super easy. You MUST be on at LEAST 26.0.2 for the commands in this guide to work. When in doubt, grab the latest copy and install them using the following instructions.
SDK Platform-Tools for Windows
SDK Platform-Tools for Mac
SDK Platform-Tools for Linux
Windows:
Unzip the folder somewhere on your hard drive.
Go to the folder containing the adb and fastboot files and type "cmd" in the path bar at the top.
A command prompt should open with the current folder showing on the prompt.
Type the following commands:
Code:
adb --version
fastboot --version
You should see some information appear. If that is the case, you were successful!
Mac/Linux:
Unzip the folder somewhere on your hard drive.
Navigate to that folder with your terminal.
Run the following commands:
Code:
sudo install adb dmtracedump e2fsdroid etc1tool fastboot hprof-conv make_f2fs mke2fs mke2fs.conf sload_f2fs sqlite3 /usr/local/bin
sudo mkdir -p /usr/local/lib64
sudo install lib64/libc++.so /usr/local/lib64
Type the following commands:
Code:
adb --version
fastboot --version
You should see the version information, along with telling you they are installed to /usr/local/bin. If so, you were successful!
Unlocking the bootloader
WARNING: This WILL wipe your entire phone. Please make copies or backups of any important data. This can also go wrong rendering your device inoperable. Proceed with caution.
On your phone, open Settings, navigate to "System" then "About phone", and tap on the build number 7 times.
Go one menu up, click on "Developer options", and turn on USB debugging and OEM unlocking.
In your terminal, type the following command:
Code:
adb reboot bootloader
Next, decide if you want to do a standard unlock or critical unlock. A critical unlock allows you to directly flash bootloader files, otherwise you will get an error when you try to do so.
Depending on what you decided in the previous step, run the following commands:
Code:
fastboot flashing unlock
(OPTIONAL)
Code:
fastboot flashing unlock_critical
Follow the prompts on your device then reboot!
Flashing factory images
NOTE #1: If you have mounted /system as rw at any point (like in TWRP), you must upgrade using the factory image method. OTAs will fail because they cannot verify the integrity of the disk since its verity data has been changed.
NOTE #2: Flashing the factory images requires an unlocked bootloader. Flashing the OTA zips does not (but if anything goes wrong, you may not be able to recover without an RMA).
Updating to a new release (factory image):
Download the latest factory image from Google's website.
Reboot into the bootloader:
Code:
adb reboot bootloader
Unzip the factory image.
Inside you will see a bootloader image, a radio image, an image zip file, and a couple of flash scripts.
If you are on Windows, open the "flash-all.bat" file in a text editor. If you are on Mac or Linux, open the "flash-all.sh" instead.
Remove the "-w" flag before the fastboot command towards the end of the file. This will prevent fastboot from formatting your device.
Run the flash all script! Open a command prompt, navigate to the folder with the script, and run one of the following commands:
Windows:
Code:
flash-all
Mac/Linux:
Code:
./flash-all.sh
Reboot once it is finished!
Updating to a new release (OTA zip):
Download the latest OTA zip from Google's website
Reboot into recovery:
Code:
adb reboot recovery
Hold down the power button and push volume up
Select "Apply update from ADB"
Run the following command from the folder containing the OTA zip:
Code:
adb sideload <zip_name>.zip
Reboot once it is finished!
Clean flashing a factory image (wipe everything):
Download the latest factory image from Google's website
Reboot into the bootloader:
Code:
adb reboot bootloader
Unzip the factory image.
Run the flash all script! Open a command prompt, navigate to the folder with the script, and run one of the following commands:
Windows:
Code:
flash-all
Mac/Linux:
Code:
./flash-all.sh
Reboot once it is finished!
Rooting with Magisk
NOTE #4: This section assumes you are not going to install TWRP. If you are, skip to the next section and just flash the latest Magisk zip after installing TWRP.
Download the Magisk zip from the official thread and install the manager from the zip.
Grab a boot image to patch (either the one from the latest factory image or a custom kernel one) and push it to your device:
Code:
adb push <path_to_file> /sdcard/Download
Open Magisk Manager and click the Install button.
Click "Install" at the first prompt then choose "Patch Boot Image File". A file manager will pop up.
Select the boot image you want to patch and let Magisk Manager patch it.
Pull it off your device:
Code:
adb pull /sdcard/MagiskManager/patched_boot.img
Reboot into the bootloader:
Code:
adb reboot bootloader
Flash the boot image and reboot.
Code:
fastboot flash boot patched_boot.img
fastboot reboot
Open Magisk Manager and you should be rooted!
Installing TWRP
NOTE #5: If you just want to temporarily boot TWRP to flash Magisk and your custom kernel, you can just skip flashing the installer zip in this process.
NOTE #6: TWRP can be unstable at times given the way that security has been set up on this device (lack of decryption, failing to boot, etc).
Download both the TWRP image and zip installer from the official site.
Temporarily boot the TWRP image.
Code:
fastboot boot <path_to_twrp_image>
Flash the TWRP installer zip.
Reinstall Magisk and your custom kernel if you had them.
Reboot and profit!
Common issues
Outdated fastboot/adb: This device requires the latest fastboot and adb binaries to work properly. A lot of common quick adb/fastboot installation guides link to installers that are old. Please manually install the latest using the information at the beginning of the thread!
Using a USB-3.0 or USB-C port: Some newer USB ports do not work with fastboot. Issues manifest as weird errors during a flash. Use a different USB cable/port.
Closing statements
If there are any procedures you would like to see added (like flashing a custom kernel or booting TWRP), I am happy to add them if requested. Also, when requesting help, please be as specific as possible where you get confused. I want this guide to be clear as possible.

Thanks @nathanchance I've been trying to keep track of things to do once my taimen ships, and I've been waiting on a "how-to" post. Thanks again!

Thanks so much for your efforts. These are much appreciated. Just what we needed for Pixel 2 XL.
One can only hope that we eventually get SU Root, TWRP and Custom ROMs. The Pixel 1 XL's development was disappointing. Hopefully this phone has more.

To Ubuntu users: the
Code:
android-tools-adb
android-tools-fastboot
packages won't necessarily work. The fastboot from the repos didn't have the same options as the one from the zip from Google. So if you are getting a usage dialog after running fastboot, that is why.

Thank you ninja!

The boss is back. Thanks for the guide man

followed from the nexus 6p threads, waiting for TWRP to get stable and then it's on!

I always took the noobish method and used twrp...
If my device is bootloader unlocked and in developer mode, and in a chance I am stuck in a bootloop, can I fastboot adb the stock image and be back up and running?
Question is: with fastboot enabled, can I recover if I F up installing magisk/root?

Mods...please make this thread a sticky:good:

That's exactly what I'm doing. Waiting for TWRP, then I will buy the pixel. 6P is working perfect at the moment, after a battery replacement.

Not to sound pessimistic but if that's what you are waiting for, you'll probably never get this device lol. Even the Pixel 1's TWRP isn't the most stable thing (it's close but still).

Oh no So you're saying we might never get a stable TWRP and no good custom ROMs for Pixel 2 XL?
Any idea whether PureNexus or any of the other custom ROMs of Nexus/Pixel will come to Pixel 2 XL?
Based on my experience custom ROMs/Kernels can transform a mid range device to Flagship performance and features. I am using the 2 XL and still within the return window. If it is speculated that this phone will not have much development, then I might as well return it and continue using OG Pixel XL or get a OnePlus. Thanks.

I'm saying if that is your only deciding factor for owning this device, considering getting another like the OnePlus 5 which has a guarantee of that. TWRP may get stable eventually but it may not. I personally love the kernel source that Google puts out and have been digging stock so I'm comfortable with just root with my kernel. If you aren't, then doing something else may be a good idea.
ROMs may end up coming in the form of images though (like system and boot and such), negating a need for TWRP. We will have to see.

That's so strange. Why is that? It's a pixel which is the successor to Nexus phones so I'm not sure why the line of phones would have a hard time with twrp and custom ROM flashing.

Well few reasons...
1. A/B partitioning makes it so the boot and recovery partition are unified, meaning when you flash a ROM, you need to reflash TWRP.
2. With the Pixel 2 (XL), as stated in the TWRP thread, the secure crypto chip requires a rewrite of some things into Java, which will take time.
The Pixel isn't really a successor to the Nexus line because these are geared purely to consumers. It's Google's iPhone.

Thanks for the reply.
That is unfortunate. If we can't have custom Kernels, we miss out on features such as color control, calibration, sound amplication , bluetooth high performance audio, USB fastcharge, vibration strength control and other mods. Will this be developed in any Kernel? I'm assuming it will take a long time (if ever) to get Elemental X, Franco Kernal or anything similar.
Also for Root, I just unlocked my bootloader. If I use the Magdisk Root Manager for Root, is there any way to flash next month's security patch WITHOUT factory reset. With SU root of Pixel XL, it was usually as simple as flashing factory images (without wipe switch) and then flashing SU plus kernel.
For Magdisk, will a full wipe or unroot needed before flashing an update?

Custom kernels will absolutely be a thing on this device. I already have mine publicly available. I haven't looked into external features (and probably won't be able to for a bit as I am rather busy) but they will certainly come.
It's the same process for the Pixel 2 XL except you need to patch the boot image you are doing to flash first in Magisk Manager then flash it after the factory images.

I need Verizon, so the OnePlus 5 is out of the question. Maybe once the V30 source is released and bootloader unlocked that may be worth looking at. But it probably won't get much development anyway.
Possibly the Essential Phone (seems to be a good deal now, and it has root and twrp)
I probably would be okay with kernel tweaks and root on the Pixel 2 XL.

Help with loss of root/twrp

I need help! Here’s the story. Sorry for the lengthy post. TL;DR at the bottom..
- Was on B32, unlocked BL, TWRP installed, rooted with SuperSU
- Updated to B35, but lost TWRP and root (I don’t know how, but I assume I must have wiped the wrong things? - system? - I’m clearly a novice)
- Now I’m on B35 with an unlocked BL, but despite days of searching and researching, I can’t for the life of me figure out how to get TWRP reinstalled. I want to have TWRP before trying Magisk (have never used Magisk before, but would like to try it this time instead of SuperSU)
- From my Mac, using terminal, adb recognizes my devices.
- “adb reboot boot loader” gets me to a list of options “power off, restart, recovery, fastboot, back to previous page”. Choosing fastboot simply restarts the phone. What should “fastboot mode” look like?
- I tried flashing TWRP via adb while on this page and terminal stopped at “waiting for any device” and did nothing
My conclusion is that I need to downgrade to whatever latest version allows fastboot commands to work properly? Is this B15? If so, is the only available B15 zip the one that is on the ZTE website? Do I just wipe data/dalvick/cache and flash this zip?
Do I not need a Bootstock and Systemstock like @DrakenFX usually posts? That’s how I’m used to doing any updates.
Thank you all for your help, both past and present!
TL;DR: Would like to downgrade from B35 to B15 so that I can install twrp and root again. What’s the best way to do this and where can I find the appropriate files?

I'm not sure where you read all that BS, but if your bootloader is unlocked then you can install TWRP via EDL (Or fastboot if you have it). No need to downgrade for anything :laugh: in the past you would have needed to downgrade in order to unlock the bootloader, now it's not even needed
Download EDL Tool by djkuz and install TWRP with that one. Or you can use axon7tool by tennear, but it's much more finicky and ran entirely by commands (no UI).
And just to avoid more trouble, DO NOT LOCK THE BOOTLOADER! You do that with the system even barely modified and you brick the phone. A bunch of people tried to do something, got scared because they made a simple correctable mistake and just locked the bootloader thinking everything would get restored to stock - doesn't work that way.
Not saying you will do this, but I've seen about 4 or 5 people that started just like you and ended up doing that

Wow, thanks so much for responding to this. Sounds like this should be easy! A couple of questions before I go about following your advice:
1). Do I download EDL Tool to my computer or phone??
2). If I'm downloading it to my computer, does it matter that I'm using a mac?
Thanks again for your help!

Oh, skipped that part. EDL Tool is a .bat. I'm pretty sure you won't be able to run it on a Mac. If you can find a Windows PC somewhere to do this, it'd be much better...
But there's another way.
Issuing "adb reboot bootloader" effectively sends you into fastboot. That list you mentioned is fastboot (if it says "Start" in green, and you can scroll that, it is fastboot). Just use fastboot from the pc: Put TWRP on the fastboot folder on the PC, then issue "fastboot flash recovery twrp.img" with "twrp.img" being whatever the twrp file name is. After that issue "fastboot reboot recovery". And as soon as you are on TWRP, DON'T GET OUT OF IT. Just wipe data, system, caches; then flash a system (e.g. b10 bootstack and stocksystem), then also flash Magisk, and THEN boot to system

"adb reboot bootloader" takes me to the start up screen that says "your device software cannot be checked for corruption..." etc. and gives you 5 sec to either press up or down on volume keys to get to list: “power off, restart, recovery, fastboot, back to previous page”, but the list is all white. If I select "fastboot" it reboots the phone and starts that cycle over again at the "your device software cannot be checked for corruption..." etc page.
Nowhere am I given a chance to use fastboot commands. I'm never on the page with the green "Start".
..This all seemed a lot simpler on my Nexus 5..
Thanks for your help/patience.

I thought you had fastboot since you described the 5 seconds screen and both are very similar. It's normal not to have it though.
I think there's some version of axon7tool for Linux but I'm not sure at all. The best way would be to find a Windows computer.
I wonder how you actually installed TWRP the first time? Via fastboot?
As soon as you get TWRP you should be able to run a few commands to get fastboot back just to have it around.

I have adb and fastboot installed on my Mac and I can't remember how I got it working on my phone in the first place, but I've only ever used a Mac for all this. Terminal recognizes my device and responds to commands until I try "fastboot flash recovery twrp.img" then it says "<waiting for any device>" and does nothing.
Thanks again for the help. I'll keep hunting though. I don't have access to any Windows computer.
