[Q] Bootloader unlock - LG Optimus G Pro

My device is rooted and freegee is installed but there's no option for me to unlock my boot loader. It gives me the option to restore or backup few & to install cwm or twrp. If I install the twrp is my boot loader unlocked? & if so can I install a rom. Furthermore can someone explain the lokifying thing?
Thanks

The OGP doesn't have an unlocked bootloader. With Loki, we get around that so we can flash custom kernels which is needed for AOSP ROMs.
Sent from my 4.4 Sphinx LG-E980

OK thanks a lot!! So basically if I have a recovery with Loki support I can flash roms?

Yes. but I would strongly suggest you only flash Roms made for the E980. Many people run into trouble flashing Roms that are meant for the F240's and so on.

How do you tell if your bootloader is unlocked?

I have an R800i that is factory sim unlocked. It is rooted, using the zergrush exploit, but I havn't installed any recovery or tried to boot into recovery. Does this mean that the bootloader is unlocked?
Can I install a recovery using the auto installer method? (http://forum.xda-developers.com/showthread.php?t=1437840) Will this stop my phone from booting?, as I have heard that the recovery is installed on the kernal or something, and you need to flash a kernal to access recovery and boot up

If you have not attempted to unlock your bootloader, it is not unlocked.
But since you have a factory unlocked R800i, you can unlock your bootloader from here.
If your bootloader if unlocked you can flash custom kernels, and custom recoveries.
However, ClockworkMod Recovery is accessible from the auto-installer, and does not require an unlocked bootloader/custom kernel.
So if I use the auto installer, the stock rom will still boot. If I flash a rom from that recovery, will the recovery still be there afterward seeing as it is on the system part of the stock rom. Will a custom rom include the recovery seeing as it includes the kernal?

[Q] Downgrading CM11 to stock 4.3 on i747M

I know there are a few threads regarding this issue but I can't seem to find a definitive answer.
I am currently running stock 4.3 jellybean (rooted). My phone hasn't received the 4.4 KitKat update yet, so I wanted to install CM11 in order to get KitKat on my s3. However, I heard CM11 can be buggy on the s3, so in case things go south, I want to be able to revert back to the stock 4.3 rom. Some people have said that you can easily flash the stock ROM via ODIN. However, others said that downgrading from 4.4.2 to 4.3 will hard brick the device since installing CM11 updates the boot loader. So downgrading to 4.3 stock with a 4.4.2 boot loader will cause a hard brick according to other threads I've seen. My question is, how can I downgrade from CM11 to stock 4.3 safely without bricking? Thanks in advance.
If you are sure you are using a Canadian version of the i747m, you can flash back to stock in Odin using a stock 4.3 ROM for the phone's original carrier (Bell, Rogers, Telus).

Yes I got the phone from Rogers, it's most definitely i747M. But do I have to worry about any issues with the bootloader? I'm assuming installing CM11 will install the 4.4.2 bootloader, so if I choose to downgrade to the stock 4.3 rom, will it cause any issues seeing as I'm running a 4.3 rom with a 4.4.2 bootloader? I just want to make sure because I heard it can cause some serious problems if the bootloader is newer than the rom.

I have never come across a custom ROM that touches the bootloader. A compatible bootloader has to be loaded on the phone before you attempt to install the custom ROM. Supported bootloaders can be found in the ROM's updater script.
I assume your phone has no warranty since you rooted it on stock 4.3. Did you root it by installing a pre-rooted ROM?
You could copy a ROM to your external SD card, install Philz Touch via Odin, reboot directly to recovery, create a nandroid backup, wipe cache, Dalvik, data, and install your KK ROM.

Okay, I was just making sure because I know OTA updates can change the bootloader, so I just wanted to make sure the custom roms don't do that. As for the custom recovery, are you recommending Philz Touch over CWM and TWRP? Do you know which custom recovery is installed from the CM installer?

Oh and one more question, my phone was originally carrier locked to Rogers and unrooted on 4.3 jelly bean. I brought it in to a cell store for them to carrier unlock it for me, but they used a rooting method to unlock it (because SuperSU was installed on it when I brought it back). They didn't unlock it with a code, so I'm guessing they used something like Samsung Tool or z3x shell. If I install CM11, will I lose the unlock, considering it's more of a "soft unlock", or is the unlock permanent regardless of how many roms I flash? Thanks for your help!

Philz is based on the latest release of CWM and I prefer CWM over TWRP because I had problems flashing ROMs. Once I switched to Philz/CWM, no more problems.

The unlock should be permanent. I unlocked it using the free method when on 4.1.1 and no ROM has ever caused it to re-lock. Reflashing a completely stock ROM, including the bootloader, did not relock the phone.
Please remember that flashing and changing ROMs will always carry a risk of soft bricking or hard bricking your phone. Make sure you read all of the guides and be prepared for disaster.

[Q] A few questions about Custom ROMs

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.

Root

How do I root my tmobile m8 running Android 5.0.1 and bootloader unlock. Also custom recovery so I can flash a 6.0 ROM
You're saying your bootloader is already unlocked? It may already have custom recovery installed. Just pick "recovery" from bootloader, and see if TWRP boots.
If not, just flash TWRP with fastboot.
You don't need to root, if you are going to go and flash a custom ROM anyway. Depending on the ROM, it may already be rooted. Otherwise, flash the appropriate SuperSU version.

I know you got it sorted out. But its best to post your solution, for the benefit of others that my have the same issue/questions and be looking at the thread in the future:
For a completely stock device on Lollipop, the suggested sequence to install a custom ROM:
1) Unlock the bootloader by HTCDev.com (the process is rather self-explanatory if you follow the instructions on the website)
2) Install custom recovery TWRP 2.8.7.0 by fastboot
3) Flash the MM ROM of your choice. Most will work with Lollipop firmware (meaning, if your phone was on LP when you were stock) but check the thread of the particular desired ROM to be sure.
4) Most ROMs are pre-rooted. But again, check the desired ROM thread to confirm (as root on MM is a little different from past builds).

Possible to flash custom rom via Flashfire on locked bootloader? See video inside

I know the answer is 99% NO but still how did this person do it? Does the galaxy use a different "kind" of bootloader that allows this?
https://www.youtube.com/watch?v=bZDMHktN3sc
has anyone with a rooted (but locked bootloader) G4 actually tried the latest flashfire with a G4 custom rom like resurrection?
I tried lollipop genisys and its way faster

You can install Roms with locked bootloader.
I have CamUIX installed, which is based on the original rom.
I am not 100% sure but I know that you can not install custom roms which use a different kernel (any cm rom).
So it wouldn't be very useful :/
By the way, the rom in the Video is also a Touchwiz based rom
Sure you can... You can flash ANY rom that is compatible with stock kernel... Locked bootloader is only about signed boot.img and recovery.img not about system.img
oh interesting.. is there any custom G4 roms that uses stock kernel? i'm hesitant beacuse i have a h812 which has a locked bootloader and none of the roms that i see say that they can flashed for h812
it looks like genisys: http://forum.xda-developers.com/g4/orig-development/bl-lock-ul-android-6-0-marshmallow-t3459260 uses stock kernel..? will it work on my H812 if i flash with flashfire?
You can flash custom system images ONLY also on lollipop ONLY. Boot.img and recovery must be signed by lg to load with locked bootloader, they obviously arent so cant do a single s**t really.
