[T-Mobile LG G6 ROMs, Kernels, Recoveries, & Other ] Ken C:
I'm going to assume that you've already looked into the root thread for the device.

If you have fwul on a thumb drive and know how to boot to it from your pc you really should be good to go. Just to make your life easier put twrp and magisk on your external SD card before you do anything.

Perform the laf switch in lgup.

Go through step 1 in fwul, but when you come to step 2 you'll be better off flashing it manually.

Rooting will put twrp on your laf partition and allow you to access it from there (using the method you used to get into download mode) to flash twrp to recovery and magisk to keep root. Op has these files set to not have to worry about some of this stuff but, first time through I'd want to do it by the book.

Theoretically if you have TWRP on recovery you should be able to flash one of his prerooted roms making the whole mess easier but I've not discussed that option with him. So don't try it unless you're adventurous.

This is from the op and takes place after you do step 1 through fwul (which seems to be all you really need that for)

Biggest piece of advice I could give you would be to do a dry run of fwul and see what you get. That way you can work out any hang ups before you commit. And get a feel for how it operates.

The dangerous part is where you change the laf on the phone through the patched lgup program and have to do that cord pull deal. It seems to be good at the 10% mark. But to be safe once you get it set to go have the phone in one hand and cord in other. As soon as it goes from laf to the next partition

AS SOON AS YOU SEE IT CHANGE, PULL THE CORD!!!

Then boot into fwul and perform follow step one. Don't worry if unpacking seems to take forever, it jumped to 31% for me and felt like it got hung up. Be patient, like really patient and it'll eventually run through. Then finish out the commands that put twrp on laf.

You could if you want to do the reading, look through anything with my name attached. I had a hell of a time getting things right. Also just in case I missed something.

I'm still waking up but this should be what you need. I screwed it up a bunch of times and was probably lucky with no brick but like I said before it seems the laf switch is the dangerous part. I've been able to recover from everything else.

The link I posted is really specific and may help you more than me telling you from memory. So I'd read that after making sure you got the first part worked out procedure Wise from the root thread itself. (make sure you understand what you need to do for that part) Sometimes it's worth it to read through a whole thread to see the screw ups everybody else made plus there's a video some guy posted that shows it being done. Not to mention I could've missed something by accident.

Also just in case if you've got another sim card device hanging around I'd put the card in that and use it until you get this worked out correctly. Just so in the worst case you've got a working phone to use.

And honestly if anything I posted makes you uncomfortable hold off until you are. Things can be fixed but why stress if you don't need to?
