So I connected my LG-H811 running stock ROM 20p to my PC successfully and ran adb and fastboot to transfer twrp and supersu over to the phone internal drive. So far so good. I couldn't get twrp to flash properly, so I simply did a temporary boot and got twrp to run without flashing it as a recovery. Then I used twrp to flash supersu (SuperSU-v1.94.zip). The problem is that when I try to reboot, it says the superSU binary is not installed. So I tried newer versions of supersu (SuperSU-v2.76-20160630161323.zip and SuperSU-v2.48.zip). Each time with these newer versions it soft bricked the phone again and required a full stock ROM restore. Specifically, it hangs either on the black LG screen or the white T-mobile screen, while the blue LED flashes on and off every few seconds. To unbrick it each time, I did a restore with stock ROM H811V20p_00_0913.kdz with LGUP. That got it working again with stock ROM, but no root. There must be a way to get superSU to install on 20p (and even get the twrp recovery to flash). I unlocked the bootloader, and it seems to load, so apparently that's not the issue. Thanks.

Thanks raptorddd, but that's exactly the problem. I did flash superSU using twrp, and it seemed to install fine. I expected that I would simply get root as you say, but that's not what happened. The first time with SuperSU v1.94 newly installed, the phone rebooted normally, and the superSU app showed up, but it didn't work because it said there was no binary installed. The newer versions of superSU simply soft-bricked the phone. So I need a way to get superSU to work and not soft-brick the phone. Is there a preferred version of superSU for LG-H811 ROM 20p, or some obscure setting that makes it work?

Thanks -- that's the the exact same version of superSU I used earlier (I even ran a diff, and the files are identical). After I flashed this version of superSU on the p20 stock ROM with twrp, it soft-bricked my phone. By that I mean it got to the boot page, and the blue LED pulsed on and off every few seconds, and it never got beyond that. When I flashed superSU v1.94, at least it booted afterward, but when I opened the superSU app, it didn't even give me the option to update binaries -- it just said the binary isn't installed, and so superSU can't run, it exited.
Maybe I'll try flashing an earlier stock ROM and see if that allows superSU to flash and run properly -- not sure which ones are compatible given the anti-rollback versioning.

OK so I finally got root. The key was to copy over this file to the phone's internal memory:
Imperium_Kernel_G4_H811_v4.8a.zip
Then:
adb reboot bootloader
fastboot boot twrp-3.0.2-0-h811.img
Then in TWRP, flash the imperium kernel. After that everything worked with root, though I still can’t get the twrp recovery to flash properly. Having root is good enough for now though.
EDIT: just now got TWRP to flash using flashify, so everything works. On to unlocking...
can you please share what guide you used to unlock and root this phone? I'm having issues on finding it, im on the newest update

May I ask where you downloaded the Imperium_Kernel_G4_H811_v4.8a.zip
Did "fastboot boot twrp-3.0.2-0-h811.img" work?
What version of SuperSu did you install? I am planning on using "SR1-SuperSU-v2.78-SR1-20160915123031.zip"

You can get the latest Imperium kernel (5.0 currently) from: http://forum.xda-developers.com/g4/orig-development/kernel-imperium-kernel-g4-v1-0-t3282915
Yes, fastboot boot from the twrp image was kind of a hack, but it worked. As for SuperSU, I tried v1.94 and SuperSU-v2.76-20160630161323.zip. Both soft-bricked the phone. Maybe the newest SuperSU will work, but I wouldn't count on it given that several previous versions didn't.

I need to flash twrp and root from 20p also. One question to clarify exactly what you did,
Did you originally try flashing TWRP from TWRP? You said you flashed root from TWRP but I want to verify if you tried flashing TWRP from TWRP like:
> adb reboot bootloader
> fastboot boot twrp-3.0.2-0-h811.img
then in TWRP:
> install click on image tab.. then select twrp-3.0.2-0-h811.img recovery and flash it.
> reboot recovery (should reboot to TWRP you just flashed)
Just to be totally clear doing > fastboot boot twrp-3.0.2-0-h811.img leaves your stock recovery intact and just loads TWRP temporarily.
Or did you actually flash TWRP from TWRP and it didn't flash properly?
Thanks!

Yes, just loads TWRP temporarily. Later I installed some apps that flashed the recovery successfully, either rashr or flashify (I don't remember which)
I hope you have all the files and pc is reading your phone in adb.
Keep the downloaded twrp file in your adb folder with dwonloaded name (Ex:1234twrp.img)
Copy the file and keep in phone internal storage with names recovery.img
adb reboot bootloader (wait for phone to boot in bootloader ofcourse)
fastboot boot 1234twrp.img (whatever your twrp img file name would be)
Now you are in twrp recovery page in the phone.
Tap Install > Images (bottom right) > select recovery.img >
Now you are in next screen where options to slect recovery or boot
Tap recovery and swipe you will see [image flash complete]
Now twrp is permeant. You can restart in recovery without PC. (Tested)
I have flashed more than 6 methods to install supersu. Keep trying and reply.
Hey,
I'm not really sure were to post this, hope it's not wrong here.
I have an elephone p8000 running Cyanogenmod 12.1.
I installed xposed framework (https://forum.xda-developers.com/xposed/super-alpha-posted-permission-xposed-t3072979) via twrp using the app fllashify, everything was still working. Then I activated the module from this link https://forum.xda-developers.com/xposed/super-alpha-posted-permission-xposed-t3072979, wanted to reboot and got stuck in a bootloop.
Now I can enter the screen were you can choose Recovery, Fastboot or Normal boot, but alle three options lead to a bootloop.
Also got no AdbDrivers on my computer, as I entered TWRP custom recovery via flashify.
Can anybody help me what to do get out of the boot loop?
Would be so thankful!
Cheers,
tie
How did you solve it??
Hi I'm a new Android user and don't know much about it :'( I recently got my OnePlus 3T and I wanted to root it
so I followed a tutorial video from YouTube successfully unlocked bootloader and flashed twrp recovery then I tried to install SuperSU... well it installed but the device got soft bricked when I rebooted after finishing the installation and wiping cache/dalvik
then I format/factory reset everything using twrp recovery and it's working now but the device isn't rooted :'( tried to install SuperSU again and it got bricked again
Also I'm getting these messages on the startup screen-
1st one: Your device has been unlocked and can't be trusted. If you don't want to see this screen please lock your device by "fastboot oem lock" and erase user data.
2nd one: The dm-verity is not started in enforcing mode and may not work properly.
(My os version is 4.1.7)
device OP 3t A3010
plz help me :'(
The 1st and the 2nd msg that gets displayed is shown because the bootloader is unlocked..
Bootloops are common while flashing su...when I flashed super su for the first time, I got 3 or 4 random reboots and took almost 7 to 10 mins for the phone to boot up..
I would suggest using Magisk as a rooting method instead of SuperSU. If you use SuperSU then some apps can detect root and object to you being rooted and Google's SafetyNet gets triggered. Magisk solves this by trying to hide root from apps and Google so that you can use your device as if it wasnt rooted at all (but in fact is rooted). Go the the Magisk forum and download Magisk 13.3 zip from there.
I am assuming you are using OxygenOS (Oneplus's software) and not a custom ROM. Download the Open Beta or Stable build from here/
These steps will erase all the data on your phone permanently (including internal storage) so please backup anything in there.
To fix the DM verity error youll have to follow the steps outlined here
Once you have fixed that, flash oneplus recovery via fastboot which you can download here
To flash it go to fastboot mode, and cd into the folder where you downloaded it. Run the command 'fastboot flash recovery <RECOVERY_NAME>'.
Then run the command 'fastboot oem lock' to lock the bootloader. After you confirm the prompt on screen, the phone will boot into the recovery and youll see a progress bar. Once the progress completes and the screen turns off, be ready to immediately go back to fastboot mode by pressing volume up and power.
When you enter fastboot mode again, run the command 'fastboot oem unlock' and follow the same steps as before.
Once you are in fastboot mode, the phone is now in a clean state with no OS.
Follow the steps outlined on the oneplus website to flash a clean OxygenOS build (stable or open beta as per your taste)
Once the flashing is complete you have to let the phone boot up completely once. When you get to the setup screen, go through it and reach the launcher.
Now we flash TWRP recovery. Reboot to fastboot again. Flash TWRP recovery (I personally use blu_spark's twrp but you can use one of your choice). When it is done, boot into the recovery. Youll now be able to copy magisk zip into the internal sd. Do that, and flash it. Reboot.
Youll now be rooted. If you have any problems holla at me.
I have been using this phone for a few months now but have never been able to get twrp to work. I am currently running on android pie. Has anyone been able to successfully install twrp?
I can boot twrp and access files, if my phone is password free. If it has a password, I can type it in and I am stuck on trying decryption until it gives up. If I type it in wrong, it fails instantly. Any advice, or changes I should make?
me too, still failed to flash TWRP and custom rom
even after followed steps here > https://forum.xda-developers.com/mi-a2/how-to/guide-how-to-flash-custom-roms-stuff-t3876375/page25
nope :/
Same issue for me
no twrp is working at all...even magisk get uninstalled automatically with boot, and if try to flash any magisk module it gets stuck in bootloops:crying:
It is working fine here.
Download the last TWRP.img and installer.zip, put the installer.zip on phone (twrp.me/xiaomi/xiaomimia2.html)
1. In settings select "none" to screen lock (Just for the install);
2. Boot TWRP by fastboot;
3. In TWRP flash the Installer.zip;
4. Flash magisk If you want.
5. Reboot
6. Enable your screen lock again.
It works

Which version?
So I am not really skilled in this type of field but I need my old OP3t rooted. I tried following the installation instructions on TWRP's website for it and everything seemed to work fine at first but I forgot to push magisk onto my phone so I rebooted my phone, which I guess was a mistake. Because right now no matter what I do, I can't get into the TWRP menu to install magisk anymore. Everytime I flash the TWRP img it straight up boots my phone like normal and is not going into the menu. I even tried locking the bootloader und unlocking it again, but this does not work. I am out of ideas on what to do and need your help.
Thanks in advance,
Ceddy
Try to fastboot boot twrp.img and flash Magisk.
