Hi guys
I m new here, i dont know much about this stuff.
So i have lg g3 d851 t mobile version which is previously unlocked (i dont know which tool was used). The problem is the phone lack some base app like radio and update center ect and its unstable, so i want to flash it.
Phone statue:
+ android version 4.4.2
+ rooted
+unlocked
+bloatloader i think locked
+stock recovery
My question is
Can i install costom rom without losing the unlock? If no can i install stock rom like 5.1 or even 6.0? do i need install 5.1 before 6.0 ?
Pls help
The bootloader isn't unlockable per se. You obtain a custom recovery by downgrading to an earlier android version with vulnerabilities you can exploit to obtain root access. Then you use the root access to flash a custom recovery. You can do whatever you want (whether it be flashing a custom ROM or a stock ROM through lgup), you can always re-root. You'll never lose the unlock since technically it doesn't exist.
With that said, since the phone already has root, you can flash twrp recovery using terminal or adb and flashing any ROM from there. You can also flash the latest stock ROM on a PC using LGUP or lg flashtool or in recovery using the stock ROM by mesa.
Read through the guides here and decide what exactly you want to do based on your preferences. You can always re root if you lose it in the process.
As a side note, there's no radio app for this model as there's no FM transmitter in this device.
Hope this helps.

Hello guys, i was wondering since I've made the 5.0 update (european) if it was possible for me to flash a custom rom like cyanogen without root (because root isn't an option since llp) ?

After flashing a ROM, flash SuperSu 2.4 to get root.

But how do I flash without root ?
It's noobish question, i can't get to recovery, I've tried with the Power and vol down keys, all i can get is a menu to erase my data, thats it.
Firsh backup your data. Then go back to EU stock ROM:

Now you can root your LG G3, use TWRP/CWM custom recovery and flash custom ROM.

Thank you, I hoped there was another way, i will downgrade then, thanks.
maybe there is. Im not pro neither I received OTA for 5.0, but I wanted to have my LG rooted, so I had to downgrade and now I am running AN HD.
Hi, would like to know if it is possible to upgrade to lollipop using pc companion. I am currently rooted, locked bootloader, custom recovery. Build no. 14.4.A.0.157. If so, will I have a stock official rom with no root and stock recovery? Thanks. I would like to return back my phone to stock with latest updates.
There will be no root. I'm not sure what about the custom recovery though. Also I think SuperSU or Superuser won't be deleted.
in general there will be NoRoot.
And if you want to update to an official android version I suggest to download the ftf of it and flash with flash tool that would be easier

Hello everyone! I'm not really new to this Android rooting and unlocking bootloader stuff (I did this to my previous Xperia phones) but I'm "new" with it now because I'm now an LG user. I currently own the D855 Global variant.
So here are my questions:
1.) Is it necessary to unlock the bootloader to flash custom ROMs? Or is root enough? (I rooted my phone yesterday and installed TWRP with AutoRec for D855 users) I'm kinda interested with the Cloudy G3 ROM.
2.) Is it necessary to unlock the bootloader to flash custom kernels?
3.) What does bump mean? I haven't heard this term before.
1) No, you do not need to unlock your bootloader on lg g3 to flash Cloudy ROM or other custom ROMs.
You are not even able to unlock the bootloader on this phone currently. If you already
flashed TWRP go get your Cloudy ROM and flash it with TWRP.
2) Again no. Like I said you are not able to unlock bootloader on this phone currently.
But you will be able to flash custom kernels because they are BUMPed.
3) And finally BUMP is a way of signing boot image so it could be booted on LG bootlader without the bootloader itself being unlocked. All XDA ROMS for LG G3 I found here are already prebumped so you are able to download them and flash immediately.

Thank you so much! Another question tho, if I flash any stock based custom kernel, how do I get back to stock if in any case I would want to?
Before flashing anything you should always do backup with TWRP or other custom recovery you already have. If you did your backup there, just restore it that way.
In case you did not, you are able to use LG flash tool and flash stock kdz files.
Also you could backup your boot.img(kernel that is...) using app like Flashify and restore it with it if necessary.
And again I recommend doing a nandroid backup with TWRP before flashing anything at all.
I am on a rooted t-mobile s6 edge running the older 5.0.2 software (didn't take the update)any devolopers working on a way to just simply flash a zip in recovery for what's need to run custom roms and kernals?coming from the htc m8/m9 it just seems like things are more complicated for this device

I'm in the same boat. I'm on a 5.1.1 Rom but have the 5.0.2 base. I want to update the bootloader and modem but not sure how.
I'm afraid to flash anything..lol...flashed a kernal 2 days ago based on 5.0.2...that is it...Samsung is very finicky..and it ducks for us
The title almost says it all.
I am on a custom 4.4.2 ROM (using ND1 firmware) and want to look into upgrading to 5.1.1 or higher. Obviously rooted with TWRP recovery.
I know I'll need to upgrade my TWRP from 2.6.0.3 or whatever it is on right now to 3 or better - but I need to know if I will have to flash official stock 5.1 to upgrade to the newest firmware, if there is a newest firmware, to get the install clean with minimal errors or can I just flash a custom TW ROM and hope that upgrades the firmware, if there is new firmware, or is there a thread I can be directed to so I can read up on what I need to do to upgrade?
Or since I am already rooted with TWRP, can I just upgrade or flash my twrp to a known good version and flash a rom then be on my way?
Thanks in advance!
Dear Friend , It's all clear that if if you want to install any TW Lollipop ROMs, you need to first install a Lollipop firmware ( Using Odin ) to install a Lollipop bootloader ( do not even think of ticking the update bootloader in Odin because then you wouldn't be able to revert into KK firmware and then you can't run any KK ROM on Lollipop bootloader ) and then install a TWRP ( I recommend ShevT's one which is less glitchie and faster than the official ones because of the F2FS support !! ) and then you're free to go the way you like
