Bump!
for LG Optimus G


Hi OG community. Bump for Optimus G is here.
Now OG users can use Custom Roms & Recoveries on LG locked Bootloader with ease!



What is Bump?
Quote:

Its a kind of hack for LG Stock bootloader! We can call it new unlock method!
You can flash anything that's been Bump'd, and Bump'ing a boot/recovery image is easy to do!
Two things you need to have for flashing custom roms:
1. Custom kernel- 2.Custom recovery on LG locked bootloader?
Now both are possible


How to Bump Recovery & Boot(kernel) images?
Quote:

Unfortunately the bump site is gone. But we can use the Bump tool instead (by mronly1love).
Download it from attachments.

Put "boot.img" into bump folder and run "bumped.bat"
or
open cmd and type: bump.exe boot.img or recovery.img
or
drag *.img to bump.exe


Does this mean that we can flash CyanogenMod based Roms on Stock Bootloader?
Quote:

Yes. I can confirm it since I've booted up with lollipop roms with no problem!


How about Custom Recoveries?
Quote:

It works! Entered Philz touch & CWM touch on stock Bl easily.


How to enter Recovery on stock Bootloader while Off?
Quote:

Hardreset:
Turn off the phone. Press and hold power & volume down until you see first LG logo. While holding volume down ,Release Power & press-hold it again until you see the hardreset screen.
Now press power 2 times & the phone will enter to the Recovery!

Won't it perform a factory/hard reset?
Quote:

Yes & No:
If you have already flashed custom recovery, then there is no stock recovery to do that.

-You can enter to Philz touch & CWM this way safely.

-But not for TWRP. Remember TWRP will perform a factory reset(without wiping media(sdcard)) anytime you flash it!

-Don't flash back LG Stock Recovery.

-So BACKUP YOUR ROM & PERSONAL DATA at least for first time entering to each Recovery


How to Bump your CustomRoms?

Quote:

You need to Bump the Boot.img, which is inside the CustomRom.zip

-- Extract the boot.img. Bump it. Replace it with the old one in the Rom.zip

or

-- Extract the "boot.img". Bump it. Copy your Bumped "boot.img" to the "Bumped_boot.zip" in the attachments. Flash it after flashing the Rom.


Quote:

You can use Flashify to flash Boot/Recovery images:

Quote:

NOTE: Remember to have "Fix recovery loop.zip"(by akahroba) in your phone.
Sometimes your phone continues to reboot into recovery (Mostly happens on Jellybean bootloader not Kitkat). Flashing this zip WILL fix the problem easily. Of course you can flash KDZ instead!

nice job bro. Best choice for miui users (y)

Edit: @Loller79 will you please make miui specific solid with boot.img so that we can bump and have off charging on stock based miui?

This is for locked bootloaders, right? Would it work with other lg devices?

But the bootloader is unlockable, so isn't this just a pita...

Although an unlocked bootloader is a better choice, Locked bootloader has it's own advantages for the ones who stay on stock based roms like myself...

Yep. Bump your desired recovery & rom( bump it's boot) with bump tool.
I've already uploaded bumped Philz touch.
You can flash the recovery with flashify app
Flash your rom
Nothing else you need to do
