Install all adb drivers properly on your PC.
If you're on Marshmallow, this might help you to unlock your bootloader https://www.asus.com/zentalk/in/thread-116376-1-1.html it's a simple APK you can install on your phone.
Connect your phone to PC and reach it with adb.
Go into fastboot mode (adb reboot bootloader) and type from your cmd "fastboot oem device-info" i think is still a must to check if it worked properly.
If you're sure it's unlocked now, then flash root .zip file with TWRP, I did not flash TWRP on my ze500kl, so I think on ze550kl you can try to boot TWRP rather than flashing it as well (fastboot boot TWRPname.img), try to boot TWRP, because if you flash it there are chances to brick your phone (for example if TWRP isn't right for it), but if you try to just boot it i don't think you can damage your rom.
If you flash a root .zip file, make sure you made a full nandroid backup with twrp first, or at least to have an uninstaller .zip for it as well.. I recommend you to make a stock nandroid backup anyway before any kind of modding (espacially FLASHING).
I personally use Magisk superuser (https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445).
I don't own a ze550kl, i own a ze500kl and this method perfectly works for me. As long as you can unlock your bootloader, i think you can flash the root without problems if you manage to boot into the proper TWRP version for ze550kl.

Guys... when i tried to flash oos 3.0 on my op2 through twrp, i first wiped the data to install new rom, then install oos 3.0, it failed. I then flashed the recovery i downloaded from the thread, then restart the recovery
I cant boot into the recovery.
System can't boot
Is it called "brick"?
So i tried to flash stock recovery in pc by command, but it says "remote: device is locked. cannot flash images". any solution to this problem?
I can boot into fastboot mode
You need to run the phone in Qualcomm mode on a PC and run the recovery tool to fix you bootloader.
I did the same and it was a royal ball ache trying to find out how to fix it
Don't do what rosswaa said
Why not?
What you should do is boot your phone into fastboot mode, connect it to your pc. Flash this modified TWRP recovery img to your phone https://www.androidfilehost.com/?fid=24459283995297945. After that you have to flash this modified SuperSU (through the new recovery) https://www.androidfilehost.com/?fid=24459283995297946.
The normal recovery doesn't work in OOS 3.0 (just like in HOS) and it's the SuperSU that gives you the soft brick. A dirty flash of the modified SuperSU should fix it.
I also had your problem and I did what rosswaa said which shouldn't be necessary (I lost all my data and backups).
I didn't lose anything, but I tried doing what you said and my bootloader was screwed so wouldn't take a flashed recovery or anything (yes the modified one)
Wish I hadnt been so excited and just flashed but all sorted now
Hmm okay, if it doesn't work with flashing the new recovery img then do what rosswaa said and after that follow this post https://forums.oneplus.net/threads/installation-instructions-faqs-oxygenos-3-0-0.439108/
Obviously try what green says first, if it works then happy days
first i am really glad that someone give some advices on me. But since i am a noob, how can i flash twrp in fastboot mode? using command? "fastboot flash recovery xxx.img"? thx

Sorry i can't post link
I've been trying for the last couple of days to root my MM G4 H815 v20e but all the guides I've tried to follow have either wanted TWRP installed before rooting, or root being required before installing TWRP. No matter which TWRP I tried, none would install. Yeah, the install would succeed ok, but when I tried rebooting into recovery all I got was the dead robot. Then I came across a method for running TWRP as a boot img and installing root from there. And it worked 100%, first time. So I'm putting this method on here so anyone else having the same problems as I had, can root their phone.
This is non-destructive but, as usual, I take no responsibility for you wandering from the path and breaking something. You will need an unlocked bootloader, instructions here, and your warranty will most definitely be invalidated after this. The original instructions were in Turkish, so many thanks to the original poster, and to Google Translate for at least making it understandable.
So I take it we're all sure what we're doing with adb, fastboot etc? This is serious stuff so if you don't think you're up to it, don't try it until you are. I'm just posting the method for rooting, the other stuff can be easily found. Plus it helps you understand the system of searching.
So when you're ready, connect your phone to your pc by USB cable, ensure USB Debugging is enabled, and off we go:
Step 1 - Visit https://dl.twrp.me/h815/ and download twrp-3.0.2-0-h815.img to your sdk/platform-tools folder. Rename it to "twrp.img". Copy this file to either the root of your internal memory or external sd card.
Step 2 - download SU zip from here https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip and rename it to "su.zip". Copy it to either the root of your phone's internal memory or sd card
Step 3 - switch to your sdk/platform-tools folder, shift and right-click on a white space and select "Open command window here"
Step 4 - type "adb reboot bootloader" [ENTER] then type "fastboot boot twrp.img" [ENTER]
TWRP will now run in memory
Step 5 - As TWRP isn't actually installed, you'll need to swipe the switch at the bottom to allow it to modify your phone
Step 6 - Tap Install and select su.zip. Select "Zip signature verification".
Step 7 - Swipe the switch at the bottom to flash the zip.
Step 8 - It would be a good idea at this point to also flash the TWRP. go back to the install screen. As it is an img file and not a zip you want to flash, tap the "Install Image" button at the bottom right, choose the twrp.img file you copied to the phone, and swipe to flash.
When complete, tap the Reboot button, choose Recovery and your phone should now boot into TWRP. Now choose to reboot to System and allow your phone to restart (it may take a while longer than normal and may reboot , mine did once).
And that's your phone rooted. Install Root Checker from the Play Store and run it to confirm your phone has been rooted.
Unlocked bootloader, I guess, yes?

Without unlocking the bootloader he wouldn't be even able to boot the twrp img, since its unsigned by LG!
This is common sense
If I unlock the bootloader I´ll also fire up the twrp (not boot but simply flash twrp)
Root is just optional there
U rock man!!!
100% working!!!! i've been looking for this for so long and all tutorials were complicated and hard to follow and you came with this simple tutotial xD i have the same lg g4 h815 20e. You are the real MVP!!!:highfive:
But why? Why wouldn't you just install TWRP seeing as you've unlocked the bootloader, might as well make your life easier in the long run...
adb reboot bootloader
fastboot boot twrp.img
copy twrp.img to internal storage
in twrp -> install -> images -> twrp.img -> select recovery and swipe to install
Can't install TWRP via fastboot (fastboot flash recovery twrp.img doesn't work properly, have to flash the twrp.img inside TWRP itself).

Since you have unlocked bootloader anything will work
you can simply boot the twrp (like the op shows) and flash supersu
or rather -> copy twrp img to the internal, boot twrp (look op) and flash the twrp img (tap first the zip/img checkbox) --it will ask where to flash -> select recovery, don´t tap boot...
Then you might also flash the supersu
and now you have twrp and root

The problem with the boot loop is only in the devices that are bootloader unlocked ? My H815 (506) is locked...and i was thinking at unlock the bootloader, but, i am "afraid" of the boot loop.
No, it's random

Its because of a hardware problem, isnt?

will this work for me? or i have to unlock the bootloader first? i just want root
can i use this method for v20d? thx.
After typing "adb reboot bootloader" phone restarts to bootloader. And thats it. Typing "fastboot boot twrp.img" does nothing but writes <...> is not recognized as and internal or external command, operable program or batch file. Whats going on? Also if i type adb devices there is empty list of devices attached

You don't have fastboot installed, or you're typing the command wrong.
c:> adb reboot bootloader
c:> fastboot boot twrp.img
What happens if I want to go back to stock, will the device remain as it was before rooting and will receive OTAs and allow device encryption and all?
Hello, I know our great device does not have a recovery partition, so we need to use fastboot to boot TWRP. But muy question is, is there no way to boot into TWRP without a computer? Maybe a terminal command from Android itself, or a little script that we can run when needed? This might be a noob question, but I'm sure many here could profit from a positive answer.
Thanks

Assuming youre rooted... Ive used the reboot app on my phone. I have a 1926-7 Moto G6 Plus. It will boot to fastboot, fast reboot, recovery, reboot system etc. Look around xda and see if someone has a good reboot app or else use GP. I actually had twrp flashed permanently to my phone but it would not back up so I have to redo it. Also the phones data was encrypted and I didnt know how to fix it. I hope that you are able to find something that works for you
You can boot into TWRP via terminal command without using a computer. Use the 'dd' command ( 'dd if=/dev/block/bootdevice/by-name/boot of=/sdcard/boot.backup.img' ) to take a backup of your boot.img. Than use 'dd' to overwrite boot with twrp and reboot to recovery (dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/boot)
Later to boot your phone as normal you only have to install your boot.img backup via TWRP.
now we can install a TWRP 3.3.0 ONLY ON DECRYPTED ROMS (the lastest Havoc, Resurrection Remix, AEX, Decendant, PixyOS are unencripted by default) for flashing magisk modules or mods but it will be overwrite when we flash/update our custom/stock rom:
https://drive.google.com/open?id=1CqzvBiEfk9xucXG8UemNZMhBxDCeSV0i
How to install it:
Put the donwloaded TWRP on your plataform tools folder and in your internal/sd storage.
Boot the same TWRP (fastboot boot TWRP.img)
Go to ADVANCED and select Install Ramdisk Recovery
Check backup boot box( in case something goes wrong just restore your boot partition)
Swipe and wait until finish.
Reboot
If every reboot finishes in twrp booting just flash magisk and youll be able to boot into system.
Hi everybody
I come back on my concern to root my Xiaomi Mi 9T under miui 11.0.3.
I managed to root it by installing the magiskmanager.zip by the recovery twrp.
Here are the manips that I made via fastboot.
-Fastboot devices
-fastboot flash recovery twrp.img
I restart in the recovery manually because doing fastboot reboot recovey twrp.img it does not work.
So I install magiskmanager.zip
All is well for the moment I am rooted at startup.
May the worry is that the recovery does not stay when I restart in recovery mode I fall on the original one.
So suddenly I redo everything from the beginning and in magiskmanager I do the direct installation (recommended) and I download the app twrp on the playstore.
I download the twrp that offers and the flash via the application twrp and there surprise I restart recovery twrp mode.
Bizarre all these manipulations before it was much simpler.
Tell me if I made mistakes during my manips.
Sorry about the novel ...
Thanks for reading me
Use instructions from thread "root without twrp". Did that a few days ago and there was not a single issue. You can flash twrp (I used official) at the beginning via fastboot and you good to go.
Making long story short:
Unlock bootloader, flash twrp, flash ROM, install magisk manager, flash boot.img use magisk manager to patch boot and you got it
I INSTALLED NEW VERSION TWRP RECOVERY IN ASUS ZENFONE MAX M1 BUT PHONE BOOTED STOCK RECOVERY AND MY PHONE BOOTING LONG TIME 15-20 MINTS
Did you unlock your bootloader first, if not, the recovery you wiped will restore itself, but if it cant...?
May also be caused by a/b partitioning? booting wrong boot slot..?
Yes I unlocked Bootloader this phone first time then flashed TWRP RECOVERY for official letest version from BUGJAEGER APP SUCCESSFUL but my phone BOOTING stock recovery AND system BOOTING 15-20 minutes
Because even though you unlocked bootloader, it is still stock bootloader, root it.
I try to many time to root but not working magisk,rootking & iroot but not working . Any suggestions ??
Get stock firmware for your fone.
It should be a zip.
extract that, go into the extracted folder, find boot.img
Place this boot.img in your adb folder
adb push boot.img /storage/emulated/0/Download (note: your dir may be slightly different, notice magisk looks in default folder 'Downloads'? Note the 's' ).
Then install magisk CANARY version, and point it to the boot.img now on your fone.
If your fone is online, it will flash your boot for you at this point. If it can ?
Make a backup of what magisk leaves in your fone. If it does not, backup your bootloader after it's complete, saves the hassle of being online everytime you need to root again
I flashed magisk boot.img now my phone stuck on fastboot mode how to fix ???
Did you flash it manually, via fastboot flash boot magisk_boot.img
or let magisk flash it while online? How did you go about it?
And what size is your bootloader? Some know I'm looking for 32mb bootloaders just now, not the 64mb ones
Also, do you know if your a/b partition?
What OS?
9,10,11,12?
I download boot.img on XDA then flashed magisk after reboot (magisk_patched-23000_YdcW1.img ) this file flashed fastboot mode on.
I don't know Bootloader size
Android 8
Check photo . This is right way ??
