LG G3 Security? - G3 Q&A, Help & Troubleshooting

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

2. Flash Customrecovery using Flashify, i recommend TWRP
3. Flash Rom of choice

[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

[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 :-\

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

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.

What? H815SEA and H815EU are both international variants but only H815EU can be unlocked.
The best method is to flash boot.img unpacked from the custom kernel like SimpleGX via fastboot that will allow you to further flash TWRP in which you'll flash full kernel package to avoid software problems and lastly SuperSU
the method i followed was-
1. boot into twrp recovery with adb command(you need to have the twrp.img file in PC and also copy it in internal memory of your phone with SU)
2. flash systemless root with twrp
3. reboot
4. install flashify
5.flash twrp.img from your phone.
6. done
but there aren't as much benefits of rooting as any other phone. viper4android doesn't work. spirit fm doesn't work. xposed doesn't work properly.(these 3 were the main reasons for which i rooted)

Rooting 6.0 M8

Hey guys,
Newbie here, looking to root my M8 running on Android 6.0
I've been reading a bit and came across first unlocking bootloader, any of you guys know what to do afterwards on 6.0 since the guides I've read are on M8s running 4.4 and 5.0?
I want to flash RESURRECTION REMIX v5.8.2, any help pls?
Also, does anyone know if this ROM supports Substratum theme engine?
Thanks a lot in advance guys!
To be clear, there is a difference between just rooting (stock ROM), and process for flashing a custom ROM. Main reason for confusion, is that you do not need to root in order to flash a custom ROM (contrary to some other devices). You simply need an unlocked bootloader, and custom recovery TWRP.
Before you unlock the bootloader, backup any of your data (off-phone to computer, SD, etc.) you want to keep; as the phone will be wiped when you unlock the bootloader.
After unlocking the bootloader, just flash TWRP using fastboot. You should use current TWRP version, which is 3.1.0-0 which you can get here: https://dl.twrp.me/m8/
After that, just put the desired ROM on the phone, boot into TWRP, backup your current (stock) ROM (in case you want or need to revert) then do default wipe in TWRP (data, Dalvik, cache) and install the ROM.
I don't know if RR supports substratum. Just check or search the RR ROM thread.
Also, questions should be posted to the Q&A section, not General. So I'll ask the mods to move this thread.

Hi,

if you want to flash custom rom you only need unlocked bootloader + twrp installed

To be clear, the kernel flashes with the ROM on this device, and that is true with s-on.
There are older HTC devices, where you had to flash the kernel separately by fastboot, or have s-off (in which case, kernel would flash with the ROM). But none of this ever applied to the M8.

Thanks for the clarification, that's probably why i got confused (watched some older video on rooting, kernel, c roms and so on). So which parts of software (or hardware) would you want to manipulate with or change that would require s-off?

Always be sure to research the root/mod methods for your specific device (not just another HTC phone, etc.). Every phone has its own peculiarities and nuances.
petarcrncec said:

Click to expand...
Click to collapse
There is a number of modifications that require s-off, such as changing CID/MID, flashing modified hboots, manually flashing radios, flashing older version RUU ("downgrading") and a number of other things.
But for root, flashing ROMs, and most other common mods, just having an unlocked bootloader, custom recovery TWRP and s-on is enough.

Why you need to install xposed while you don't know about it ?
Flash in recovery by boot to recovery and tap install then navigate to the .zip location in storage and sweep to confirm that's how to flash a .zip from twrp

Root and xposed is tow different things you need root for something and xposed for a different thing
for example you don't need root to have a working xposed framework ( some modules require root though )
So it's up to you and what you will use
We can tell you what you have to do if you tell us what you up to

In order for xposed to work, you need to flash the xposed framework using TWRP, period. It's not complicated, and it's stated in the instructions clearly.

I am a bit confused here, the situation is like this: I need Xposed installed in order to use some modules mainly (Xprivacy..).
I have tried to install TWRP using Adb (Attached) which I assume it wasn't successful so far.
how to proceed now.
