[Q] Any reason not to update firmware on new2me G3?

Hi all. This is my first LG phone and I looked around but didn't see any reason not to fully upgrade firmware before I root. Any input any drawbacks of upgrading fully? Also, this is a t-mobile used phone and the back of the battery case has a wireless charging stickon in it. Is this standard for this phone? I havent researched the look/brand of it yet as I have just got it. Thanks. Its a nice phone. Can't wait to get tweaking!

The latest build 10R broke all the rooting tools.
Assuming you are still on build "c" or "m"...
Root first w/ PurpleDrake and make sure it installed (TWRP) custom recovery. It should also install SuperSU but I can't remeber, you may have to read a bit.
I would then update to the latest TWRP version which can be done easily with TWRP manager. Make sure you install busy box when prompted by TWRP manager!
Perform a nandroid backup before updating!!!
Then flash the "R" firmware with TWRP flashable zips available here.
Be certain to flash SuperSU before rebooting! If you forget there is no way to get root again after a reboot.
Good luck...

Thank you. I actually found that out the hard way. Flashed back a version and got root. Wifi calling and text not working yet so I found the exact thread you posted and was gonna try. Great tip on flashing supersu though. I'm new to LG but looking forward to getting this phone right. Thanks for the input.

Here is another great source of various upgrade, downgrade and restore to stock flashing methods and tools including TWRP flashable Stock ROMS. Make sure to read ThePagels OP carefully before proceeding.
Also in the OP: "Strengthens and weaknesses for each method click here" is also well worth reading.

[Q] Correct way of having stock lollipop + root

Hi,
on tuesday I, will get my G3 (should be d855, as im in germany) and obviuosly I wan't to have root.
As it seems to be a bit tricky on the G3, I want to make sure that I got the correct way of achieving that now.
1. As it will be new, i think it should still have Kitkat, if it won't, i have to downgrade.
2. Use PurpleDrake to root it.
3. Use Flashify! to flash TWRP 2.8.4.0
4. Flash bumped Stock v20F and SuperSu via TWRP
5. Be happy to have stock lollipop + root
Can i do it like that or am I something missing?
Thanks

Step 1, 4 and 5 are impossible to do with Lollipop. Stock Lollipop can Not be rooted. You`ll have to flash a Lollipop custom rom after step 3.

Enter twrp and flash supersu 2.40

Yes, i meant the stock rom flashed with the LG Flash Tool cannot be rooted

Puuh, alright, so if we replace "stock" with "bumped stock", then everything will work like i wrote in #1?

[Q] D851, BUMP, TWRP, and Stock Lollipop Questions

Hello, I have the T-Mobile LG G3 D851 and I've been trying to find the best configuration. I came from a Nexus 5 that I would either run stock 5.x or CM 12. The CM12 for LG G3 is great but it doesn't have a good camera.
Anyway, I've come to enjoy the stock firmware that LG puts on these phones. So here's what I want to accomplish, however I feel I cannot find enough information to do it confidently.
I would like the have TWRP installed with Stock Lollipop 20b, with root.
Can I just bump a TWRP image and use flashify or something to flash it? or dd?
I installed the 20b KDZ and rooted using the one click method, and that's how my phone sits currently.
From what I understand I need to downgrade to do something with the boot.img so that I can manually flash 20b with a bumped recovery? I'm not sure what bump really is entirely. Do I need to bump all TWRP images that I install? If bump is required for the G3, do they not come pre bumped?
I know that my first go around, I had flashed TWRP with flashify, then installed CM12 without any issues. So I'm wondering if this is just for stock ROMs or did they do something to the boot in 20b that would stop anything from installing without being bump'd?
I also noticed most of the bump'd threads don't list the d851 so I'm wondering if T-Mobile doesn't require this?
Keep in mind I've searched and read extensively and cannot come up with a clear picture of what to do. I've become too used to Nexus devices it seems :-\

Thanks, and finally, do I need to bump the TWRP images from their site? or are they good to go?

D851 has unlocked bootloader. You don't need bump. Just flash twrp via trwo manager or get the inage and use flashify.

Great to know! Just used flashify and it worked like a charm

Best upgrade path to lollipop

I'm currently rooted and bumped, twrp 2.8.5.0 and android 4.4.2
I was waiting for xposed to be available before upgrading, and am now thinking about using a newer 5.1 based ROM
What's the best upgrade method ? (Preferably giving me an option to switch back if I need to )
I like the idea of multirom, but I've got the 16gb version so space is at a premium

Depends on what you want? Do you want AOSP or Stock ROM

Aosp is fine, but what would be the difference between the two v methods ?

Nothing too significant
AOSP you would install from KitKat and then install most of the lollipop system partitions after if necessary
Stock Rom you would just OTA or Flash Lollipop KDZ and then root

Thanks, I'll look at this today.

easiest way to get to LP is by getting your current firmware from here: http://lg-firmware-rom.com/
then upgrade to that kdz from with lg flash tool 2014, from here: http://forum.xda-developers.com/showthread.php?t=2797190
then root with this tool: http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
then, use an appropriate method correlating to your model number. try imageprep.
I'd suggest restoring, not upgrading to LP.
to roll back, you can of course create a nandroid before all this. move it to your ext_sd card before any flashing, too.
as for xposed, it says it's in alpha, but i haven't encountered a single issue with it and i've been running it for a good month+. tweaksbox works like a charm too.
as for multirom, i've never tried it, so can't speak for it.

can I root & twrp VS985 5.0.1 24B?

There are lots of guides to rooting the Verizon LG G3. Many of them are older and have problems working on the 24B software version of Android 5.0.1. I guess I have 2 questions: 1) Is there presently a method to root this phone? 2.) TWRP says, "you must be rooted and vulnerable to BUMP to use TWRP on this device." I don't know what vulnerable to BUMP means. Yes, I know I could try to Google it, but I haven't been very successful at finding an answer that I understand.
EDIT: Root achieved. Still looking for a reliable install process for TWRP

Have you had any luck getting TWRP on stock 24B? The only option I've seen is to bump TWRP to 23C and use JasmineROM 8.0.

I was able to get TWRP on my rooted 24B with a new version of autorec @bender_007 used the firmware from my phone to build it. Where else can you get service like that! When you use 24B version from that page, you may be on TWRP 2.8.6.1 If he hasn't had a chance to update it yet. You can go to 2.8.7.0 if you want, but be certain to use the version from 777jon thread and NOT directly from TWRP. In all cases just double check you are getting the correct version for your phone. You should be able to run TWRP with no errors, and the install could not be easier. Just follow the instructions on the OP. Enjoy!
