First you should do some reading just to brush up on flashing. TWRP is a recovery, not a kernel. I think there is a how to guide in forumland somewhere. You have to root first using purpledrake, towelroot, uproot, etc. Then you need to get the latest twrp .img for your appropriate model phone. Flashify that. Pick ROM of your choice and voila. Backup your stock just to have it. But seriously I would definitely read up before you break your phone.

[Q] I've rooted the LG G3, now how do I install TWRP and flash a stock firmware?

I've rooted the LG G3 (D855), now how do I install TWRP and flash an unbranded stock firmware?
For some reason PurpleDrake didn't install TWRP for me.
I also backed up the EFS partitions because it was said here on the forums to do it.
Thank you in advance.

do you have the d851 because that is the only one with unlocked bootloader
We do not yet have "full root". they are working on unlocking the boot loader, but it is being worked on and last I looked the devs fully believe they will be able to do it.
Take this time to read and learn as much as you can.
Have fun.

[Q] Root + Recovery question

Hello,
I always had a HTC, so I'm kind of a new with rooting and unlocking an LG.
I have a LG D855 international and I have been reading a lot in this forum and I think that I've figured it out. But I just wont to be sure.
So if I'm right than I can root my phone by running purpledrake. When I've done that I have to install SU.
But if I understand it correcly the only way to get twrp is with" Bump'ed TWRP" so it's only possible to have TWRP if I use a custom rom?
So it's not possible to have orig Rom an TWRP? Right?
But If I just root my phone with purpledrake, so without installing TWRP and without custom Rom, I would still be able to use EXPOSED? RIght?

Yes Purple Drake is currently the most reliable root method, once you have root you need to install the SuperSU app of your choice.
Don't confuse yourself with Bump! Just accept that this is the only recovery that works with the G3 and install it then use it like normal. You will only be able to flash custom kernels (and roms with custom kernels) after they have been bumped, this is something the developer will do for you not anything for you to be concerned with, and fairly soon (when this method is released) all custom roms and kernels you find on xda will be pre-bumped - so basically you can treat the recovery like you always have done.
Xposed is nothing to do with recovery and everything to do with having root access.
Does this recovery back up my stock rom safely? I'm hesitant to use it because I've never heard of bump.

Nope, afaik, once on bumped twrp, u can't restore stock recovery. For that you will again have to flash the stock KDZ.
OK so it's only for bumped roms. Thank you

The user above you is wrong and didnt read your question properly.
You CAN back up your stock ROM, just install bump, head to recovery and do a backup - you will never get stock recovery back though, unless you flash a KDZ with Flashtool.
But yes you can use TWRP to back up your currenty stock ROM.
Okay I get it the only way to restore the rom that I backed up is to add bump to it! ok I got it but in order to get back my stock phone I'm going to have to use the LG flash tool right

Thanx a lot.

LG G3 Security?

Hello. I am planning on getting a LG G3 and I just wanted to know if there's some kind of security protection (like S-ON on the HTC One) that'll hinder flashing new firmwares and ROMs? I've already read up on how to Root, Unlock the Bootloader, and install a Custom Recovery.
Nope. All you have to do is flash the recovery image with flashify. And download roms and flash away. Very good phone. And lollipop is very nice on it

There is no protection..
1. First root device
http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
2. Flash Customrecovery using Flashify, i recommend TWRP
3. Flash Rom of choice

How to pass LG G4 Marshmallow to CM13 or another custom ROM?

Hello, has passed a lot of time since my last thread. This time, I'm requesting your help about something that every time I read a related thread turns more complicated.
I just want to know if I can flash CyanogenMod 13 or another custom ROM if I have an LG G4 with official Android Marshmallow V20c (not rooted and with locked bootloader, because I don't know if I can take the risk), because I learned how to root and unlock the bootloader, but for example, CM13 needs a V20a stock ROM and when I flashed that version with LGUP I didn't have signal and com.android.process wasn't working.
I hope you can give me a vision, very easy to understand, because the threads are not very explicit.
Thanks and regards!

As simple as possible: no!
With MM and locked BL you can't get root and you can't install any custom Rom.

You don't understand me. I know how to unlock my bootloader and after that root my phone, but I'm not taking the risk because I flashed the V20A stock ROM to install CM13, but I didn't have cellular signal and because that I didn't try to unlock and root my phone.
Maybe this question is more useful: Can I install CM13 when I have a V20C stock ROM and not the V20A one?
Thanks and regards.
You can flash any custom rom if you have unlocked bootloader and custom recovery e.g. TWRP. Without that things you can't flash anything, because custom roms needs unlocked bootloader.

OK, now I understand that I can flash CM13 over V20C and not necessarily over V20A.

You can flash CM13 on any V20... (V10 being LP, V20 MM) as long as you have a MM base you can flash. However, as said above, you MUST unlock bootloader to flash CM, don't try and flash custom ROM without unlocked bootloader. You can unlock bootloader on any version as long as yours is one of the models with the ability.

Best way to root,unlock BL and install custom recovery

I have Xperia z1 compact running stock non-rooted 14.6.A.1.236 rom. My bootloader is locked. I want to be able to install custom roms. What's the best way to root, unlock bl and install custom recovery? I've been searching forum for past few days but most of the download links redirect to d-h.st. and that breaks the chain of needed files.
Also i never used flashtool and i don't know should i use Sony flashtool or "original" one

I don't think so. Just need adb...
I guess I don't have to open a new thread for this: I've been reading a lot about this recently and trying to get my thoughts straight about this:
I found PhilZ Dual Recovery (https://forum.xda-developers.com/showthread.php?t=2647480) which works with locked bootloader. Some people wrote there they installed the recovery on 5.0.2, so it seems I have to downgrade first (I'm on 5.1.1), even though it doesn't say that in the manual..? - if you can't answer that I'll ask that later then in the linked thread.
Next thing: I rooted with Kingroot, but want to switch to SuperSU - cant switch because theres a problem with the binary, so I have to flash it anyway through custom recovery.
Can I now root with Kingroot, install PhilZ Dualrecovery and when it boots into Recovery Mode, can I just flash the SuperSu.zip?
OR would I need to boot normally first after custom recovery install, then uninstall Kingroot, to unroot, and THEN flash SuperSU in Recovery?
Ive been using root for years but never really got into flashing before so I'm quite new to that and appreciate your help. Thanks a bunch.

You don't have to downgrade to flash NUT. It's been a while since I did it, but I'm pretty sure that flashing supersu won't totally remove Kingroot. Best thing to do once you're rooted, if you don't want to unlock bl, is probably to install recovery, then in recovery flash a prf, which will wipe your system and install new system with supersu instead of Kingroot.

I don't trust any universal rooting apps. Only way to legit root your phone is to downgrade to kitkat and then root using exploit, then flash prerooted lollipop (that is if you wan't to stay on stock rooted rom). If you don't plan on staying on stock room and only want quick root you have to use kingroot since that's only universal root that can root z1c. When it comes to recovery there you have two choices. To use xzdualrecovery or to unlock bootloader (you will loose drm keys which means you will lose stuff like x-reality) and flash normal recovery. I would go for dual recovery because if you ever wan't to get back to stock you can since stock recovery isn't getting overwritten with xzdr. But if you choose to unlock bootloader first backup TA (you have to be rooted) and then unlock.
Hope this helps

I would go with unlock bl method. You can restore TA after rooting so you done lose drm, and it's easy to root with unlocked bl - https://forum.xda-developers.com/showpost.php?p=72547776&postcount=6
