hi guys .I have a V500,and I had flashed the TWRP on my device. And then I flashed a custom rom such as cm11. But ,in my opinion ,many phones flash roms must unlock the bootloader first . and then flash the recovery etc. But why our v500 don't have to unlcok the bootloader ?
Does LG provide the offical bootloader unlock service? Thanks.:angel:

Lg make their devices with locked bootloaders in contrary to asus nexus for example who allow you very easily to unlock the bootloader. Developers use a hack named loki to bypass the bootloader and allow us to flash custom roms and recoveries. Thats why you see a message if you re on a custom rom everytime you open your tablet, it means that loki is working fine at that moment. If we had unlocked bootloaders we wouldnt see that message as there would be no need for loki.

I'm trying to root/flash custom ROM for my Optimus G (Rogers) and I'm very worried since this device is very expensive.
Is our device 'code' name lg "Geeb"? If it is, does it mean that I can go download and flash all the roms that supports "Geeb devices"?
Also if I unlock bootloader, and want to get warranty service from LG, I understand that I gotta flash original kdz file for my phone.
Does flashing KDZ file relock the bootloader and remove root? (so like factory stock reset?) or does the bootloader stay unlocked?
Thank you.

If ur device is named as Geeb, then yu can flash all the roms for geeb...but yu need to have rooted & bootloader unlocked..
Yes flashing KDZ will remove root and lock the bootloader and by doing hard reset yu ll get factory stock...

Hello, if your bootloader status is Bootloader unlock allowed: NO, then you can't (for now) unlock it at all (No solution available to date)...hence, you can't install a custom ROM like Cyanogenmod because it contains a custom kernel, and a custom kernel needs an unlocked bootloader.
Everything is possible, a developer on Xperia SP made a CM12 (latest Cyanogenmod ROM) rom for LOCKED bootloader, but unfortunately it's not yet available for our Xperia M.

there is a cwm recovery for locked bootloaders but you can only flash stock based roms (theres 2 stock based) i don't think they are for dual sim tho
Hi guys
Bootloader unlockers/lockers from recovery are here.
Easy method to unlock & relock Optimus G bootloader.
Good things about these zips:
1. No running OS is needed.
2. You don't have to be on lg stock roms.
3. Work much faster & easier. Less than a minute.
4. You will still have custom recovery after locking your bl.
How to use?
Using bumped recovery, flash them like other zips in recovery.
Don't have recovery?
Flash a bumped recovery img (inside of the attached zips) with an app like Flashify or Kernel Adiutor or etc.
Note: BL unlockers flash unlocked bootloader + Philz/CWM recovery. Booting up on unlocked BL needs unlocked kernel.
So in stock roms, don't forget to flash an unlocked kernel, like unlocked stock kernel or solid kernel or etc...
Anyway in case of any problem, there is no worry because you can always access to Philz touch(for E975) or CWM(for other variants) recovery.
I could only test E975 ones. Other variants unlockers must also work. But you are the testers...
Mirror links (files folder):
https://mega.nz/#F!4JwWCJZB!3jFrgKSdRhAhdwLadD_YaQ
Please Note:
1. I'm waiting for your feedbacks. Please give feedback with name of your variants.
2. I didn't have stock bootloader files for other variants, so I could make bootloader locker for E975 only.
Some guides:
1. How to flash boot/recovery .img in Kernel Auditor?
In the Backup section of the app, use Flash IMG button, then select your .img file (extract them from zips), then select the partition to flash (boot/recovery).
2. You can use your own bumped recovery img, using the bump tool
3. On locked bootloader you can enter to recovery with hardreset method.
4. After flashing Makoz30f Flasher (not after unlocking, unlocking is ok), it will also flash bootloader tz.img & rpm.img.
Flashing Mako rpm.img will cause false heat issue on LG roms so your screen brightness will not go further than 63%(& cpu clock speed further than 1188000). E975 unlocker & relocker zips will replace tz & rpm partitions with stock ones. So you can use them to fix this problem.
Whats mean stockboot?
Btw thanks, no instal freegee to unlock bl , nice job

for other variants of og, after unlocking, you need to flash an unlocked kernel, but for E975, if you use the zip that has stockboot, you dont need to do anything & it flashes the kernel for you.

Since Gee3 rom has better speed & LTE support in our stock roms, I'm making Gee3 v1.3 & I'm testing it, but with this kind of statistics , it seems there's no motivation no replays about its working on other variants...

MMK instruction
Hi MMK,
I'm a total newbie and it's the first time i've ever flashed a device, my E975 is completely stock (but i've root privilege and su is installed). I've installed flashify and downloaded a zip (i don't have a special kernel at the moment do you suggest stockboot). Now i've unzipped the folder on the phone but i'm uncertain about what to do now, there are a lot of images and i really don't know where to flash what. Can you suggest a more detailed procedure?
Thank you for the effort and thanks in advance.
great job bro ^_^

Hi, If your bootloader isn't already unlocked:
In flashify you must choose recovery image from flash section, then choose the Philz.recovery.img you've extracted.
Then press reboot to recovery from options & simply flash the zips in recovery mode to lock or unlock your bootloader.
Make sure to use your own variant zip.

If you want stock based roms like Sling Kahroba,
Before unlocking, flash a bumped recovery & install the bumped Sling Kahroba... Easy.
PS: you can't use lockers because they're only for E975 variant.

Check your variant & go for it...
I've described what you should do on stock rom & locked bl.
Start with Flashify & follow the procedure.

You can buy from any carrier you want. You don't need to unlock your bootloader with the g3

The G3 has an exploit called bump! which fools the phone into thinking it is receiving genuine LG images(i think that's how it goes), so there is no need to unlock the bootloader. Our custom ROMs come signed already, so just flash like you normally would.
& FWIW the vs985(verizon) comes carrier unlocked out of the box so any sim should work...you just need to manually set up the APN for data.
Thanks for your reply

That means i can purchase any carrier & i dont need to unlock bootloader .. right ?????????
i would just need to flash recovery & then just flash rom right ????

what do you mean by root .
if bootloader in unlocked then just we need to install custom recovery to flash custom rom right ?

First you'll root your phone.
Then, you'll install autorec so you can have a custom recovery.
Then you can flash any rom you like that's compatible with your phone model.

There are valid reasons to lock your bootloader, but it shouldn't be done with unofficial software (a Custom ROM).
When the bootloader is locked, only signed software is allowed to boot, so only official ROMs can boot.

Correct
why would you want to loick the boot loader after a custom rom is installed to begin with?
