Thanks for this guide. Originally I tried to flash a rooted TOT file, which errored out and bricked my phone. After seeing this, i restored it with the 20a file and ran the program. The phone rebooted automatically, so I booted into TWRP and mounted my phone and transferred the no-opt-verity by USB and flashed it. From there I flashed Resurrection Remix, Gapps, and Magisk. Everything is working great!
Which Rom is Resurrection Remix? Is it Nougat? Can you direct me to more info on Magisk? Is it an alternative to SU?

Everything is working great, have root. The one thing I never did was format data in TWRP, if I boot into TWRP and format data will I lose root? (I want to install custom Rom)

Yes, it's on nougat. And magisk is a systemless alternative to SuperSU that lets you install modules and bypass safetynet. Google them up.

This method worked for me I was able to roll back, unfortunately I had to go back to stock in order to unlock the sim (T Mobile). But will go back to V20a when I do that so I can flash a custom rom. Thank you for the images in your post they helped a lot!

Btw is this the only method to flashing TWRP? How come you can't flash it like you would flash a Nexus device with the "fastboot flash recovery twrp-3.1.x.x-xxx.img" command?

You can't flash using fastboot flash commands on H830 because they are disabled by T-Mobile (on unlockable H850 they do work). That's the reason. There is also a tot method too which is quite dificult and annoying.

The phone reboots fully, no errors or messages. But the computer just continues to show the message "Selinux is ours! Rebooting".
Btw, thanks for this guide. I have used it on 3 phones already without any hiccups. This is the first one giving me an issue.

Finally Worked!!!

I am not sure why this worked. I removed the memory card and used another cable (before, I was using the white cable that came with the phone). Started over and everything went like a charm.

:good::good::good:

Little error that caused me a big problem: Make sure and disable lock screen security so that the phone boots into MTP instead of charging only. Also that the internal storage read 0mb and I had to flash no verity from external sd card.

Hope I can help ;)

This is able to see my phone:
adb devices

This works to get my to Fastboot Mode
adb reboot bootloader

This is stuck on <waiting on device>
fastboot oem unlock

I have 4.2.0 of LG Mobile drivers installed...seems to be working enough that adb devices sees the phone...but in fastboot mode, maybe drivers for that are not installed or working? I only found where someone installed Android SDK and that might have fixed their problem? Going to try that now.

Update: Android SDK install did nothing. Also found a registry hack that worked for another device, did nothing for me. Tried same steps on a laptop I have...install LG drivers, run adb commands, worked without issues. FWIW, I tried *all* the USB ports on the front of my desktop, not any on the back. But, seems to be working fine on the laptop now. Proceeding through remaining steps. Thanks OP.

re-lock bootloader?

Looks like I got it all done. Went much quicker on the laptop than my desktop.

I did have the script 'hang' a bit...and while I was poking around in TWRP, it started to act like it had a mind of it's own...selecting various options...then it rebooted and the script was done.

I now have Fulmics 5.1 installed and working.

Is it possible to re-lock the bootloader?

Is there such a thing as

> fastboot oem lock

Bootloader can be relocked using same command you mentioned. But make sure you're on stock firmware before relocking bootloader to avoid any problems.

What I was wanting to try is get Fulmics installed, then somehow 'lock it down' so security software for work wouldn't get angry :)

I understand that Magisk could probably circumvent that the root side of things, but i prefer to not have anything that might cause problems.

So, I installed Fulmics, then tried to fastboot oem lock and on reboot, it was not happy, got a red color message that said it wanted to power my phone down and did not want to boot.

Thankfully, Uppercut was able to push the latest 20m KDZ back on to my phone...so I'm back to stock.

Yeah, If you want TWRP and custom roms then you need to keep bootloader unlocked. Off course you will have to be ready to face angry software security agents. And as your on 20m now you will have to roll back to 20a to root because autorecowvery won't work on this software.

Hii.. I want to ask, root & unlock bootloader can unlock sim to use with worldwide provider?

Because my phone is network lock.
I'm from indonesia. Thanks
Rooting and bootloader unlock is different from Sim Unlock. You will have to ask your carrier for unlock code to network unlock your phone, unlocking bootloader is not going to do anything in that case.

Hhmm.. Ok thank you for your information. T-mobile is not support in indonesia. So, should i call T-mobile technical support to unlocking my network?
