I have an LG G3 D855 32GB. I have attached the Software info screenshot below.
I am wanting to root, add TWRP or whatever recovery, and install the CM12 ROM (or if there is something better you could suggest). The phone is currently running android version 5.0 as shown in the screenshot.
What is the best way to do this? I have been looking around and haven't found any for sure way of doing this.
Any help would be appreciated, thanks!

How would I do that? And which would be the right thing to flash with, because I don't see many other LG G3s with the same software as me.

Thanks you very much, I have cyanogenmod and twrp installed and it's working perfectly. I was wondering if there is anyway to get the original camera app from the stock ROM, I have tried a bunch of other ones and they don't seem to be nearly as good.

Lg G3 Rooted but cant install TWRP

hey guys
ok so i rooted my lg g3 d855 and i have verified it is rooted with several apps. i tried to install twrp as my recovery and i have tried two methods
1. via ADB shell
2. an app called flashify
both say it has been installed and they reboot my phone and instead of gettin twrp recovery i get a black screen and a green and red flashing LED, i have left it for 10 mins thinking it was installing but nothing. i have to remove the battery to restart and it works fine (minus the twrp)
also i have checked i am using the correct recovery img as my model number is the d855 and the twrp is d855
please help!
also google has not helped
also please dont use big words as they will pass straight over my head
thanks in advance

you sir are lazy
if you did bother to search properly you would know that TWRP has not been ported to work natively with stock Lollipop on LG G3

oh? so i have a rooted lg g3 that i cant put a custom rom on? is there anything i can do?

I did the same thing like OP and now my phone can't boot into recovery or download mode. So I can't flash it with LG flash tool. Is there a way to revert back to stock recovery?

Can you tell me, now I stuck at this waypoint can I do anything? Maybe downgrade to KitKat?

bro check if inside the back cover it is d850 .if it is u have probably bought it for less money so to flash twrp u have to select img of d850 nd flash it using flashify.believe me bro it will work as it for me and u probably may have a problem of no update to lollipop then go for it .sorry for bad English

Facing same problem.
Could somebody help me.

D852 Fido
Hello there
I am new to this forum and to rooting devices and I apologize in advance if I can't even express myself properly.
So, I have D852 from Fido (Quebec) that I really like and want to keep.
Until recently, it had stock MM and everything was fine.
I downgraded to LP 5.0.1 Telus and managed to get it rooted (phone works fine but no data since downgrade).
I then tried to install TWRP and for whatever reason, it doesn't work.
I used ADB, AutoRec, Flashify, TWRP Official App, nothing works.
They all show that the installation is successful but when I try to boot to recovery (Quickboot, ADB, Power&Vol-), all I get is red/blue led flashes then I press Volume Down and the phone boots normally.
I really want to get TWRP on it so I can flash the latest Oreo on it.
Thank you in advance

Would updating to Marshmallow and using MM Autorec help with installing TWRP on the D855? http://turbobit.net/fg6nmu0ujhpo.html

Probably should have started a new thread, this is for D855. For your D852, try Marshmallow Autorec, worked for me: https://mega.nz/#F!rtI1naZT!LJIKUVpv8fYjrvhpykA4_A!2o433RBZ

Hello, I have problems with my phone. I need help almost desperately.
I can't do anything with my phone now. As you probably read, until about two weeks ago I had Fido stock MM on D852.
I managed to downgrade to Telus LP 5.0.1. After the successful downgrade, I was able to root my phone but not to install TWRP.
Now I can't install any KDZ, not even going back to Rogers/Fido MM.
How can I PM you for faster and better communication?
Thank you in advance,

Hello Whatsgoingon,
I can't try MM because the phone doesn't let me flash original Rogers/Fido (D852) KDZ.
I am currently rooted on LP 5.0.1 and I do get OTA upgrade message to MM. Should I upgrade then try your method?
Is there any risk that I will not be able to do it and get stuck with MM without the ability to downgrade to LP or KK again?
I only want root and TWRP to be able to flash custom ROMs.
Thank you,

I can't make any guarantees, but for me it worked.
I had no other option as I was stuck on MM with no kdz/tot for Lollipop or Kit Kat for my D852, so I have no experience downgrading. It worked great for me on MM and I tried everything else to get TWRP on my phone.
This file does not seem to be restricted to a specific carrier and is supposed to work on all D852s, but you can check this thread to see if anyone tried it on a Fido: https://forum.xda-developers.com/lg-g3/general/apk-flash-twrp-autorec-thanks-to-t3081396

Running the good ol' KitKat 4.4.2 Need guidance to update

Hi I just bought a LG D855,
It's currently running the old KitKat right outta he box. Build Number: KVT49L, Software Version: V10n-GLOBAL-COM
The phone is missing the Update Center and thus I don't get any OTAs, I've decided to flash a custom MM for the phone. However while I try to flash TWRP via Flashify, it reboots into Fastboot and I see no sign of TWRP. Is there a specific TWRP I have to flash for KitKat?
Also, should I first update to LL and then to MM? I'd like to use any custom MM rom close to stock there is.
Your suggestions will be greatly appreciated.
Kind sirs, pray link me to the ROM that's closest to stock for any suggestions you may have personally. :highfive:
Thank you so much in advance.:victory:

Now that you've asked to check if it's D850 or D855, please check the image attached. IMEI sticker says D855, so does IMEI Checker but I can see D850 written on the sides by the camera. Can you please confirm?

You should always always backup every partition. Especially efs.
Anyhow, what service are you trying to use? GSM or CDMA?
If your using it with GSM, and If this phone is truly a sprint phone, it probably got sim locked when he fixed it. I ain't no expert but it probably needs unlocked if this is the case.
Edit: I just understood what you wrote, that he already unlocked it. Sorry for misunderstanding.
But if your using it with sprint, maybe it just needs activation updated. I don't use sprint or CDMA so I don't know a lot about that.
But main thing you need to do before anything else. Is make a full back up of your partitions. I always make backup in two.( Which is mainly all you need)
But also there are programs that (I can't remember there names,) make backups of all your hidden partitions, just in case.
I understand I didn't provide you with a definite answer to your problem but hope it can help.

Can to send me a copy of your build.prop
Edit. Are you using sprint stock ROM? What version? Are you sure it's unlocked? If yes, I might be able to help. But I have to gather some info. And get to my PC. Cause I'm testing a ROM right now and am lagging

I have faced the same problem and, managed to solve it. Here is the solution..
1. Download any kk or lp firmware of n910p. Extract the .tar file, get the ' modem.bin' and flash it using Odin. Do it twice, yes, twice. Before flashing the modem, make sure you have unchecked 'auto boot' option in Odin. To turn off the phone after the first flesh, just take off the battery.
2. Download twrp 3.0.1.0 for n910f. Yes.. TWRP recovery for N910F ( or the model specified under the battery). Flash it using Odin.
3. Download any stock based custom ROM which is based on the modem you have flashed. For example, BOB7, COG5 , COK1( these are the last 4 characters of the stock firmware/modem)
4. Flash the custom ROM using twrp, flash gasps, and smile.
If you face bootloop, just try different kernel. I'm using BOB7 modem, emotion kernel, vision x custom ROM.

yes i am sure phone is unlocked through Domestic Unlock ( z3x & octoplus Boxes)
also i am on Stock 5.1.1 lollipop
I think the only way u can help me is by sharing a good QCN and EFS for N910P ! (if the above solution from our friend doesnt work 4 me )
Also i am from another country so there is no harm for you if u share it with me in private.
Thanks in Advance !

You might be able to get some help from the thread that you downloaded the ROM from that you're trying to flash. Since you're still on lollipop make sure that's not a marshmallow ROM you're trying to flash. Good luck to you. Once you get it all figured out you're going to love it!
