What is BOOTSTACK ?

Bootstack is a bunch of files placed deep inside your phone. They are responsible for turning your phone ON and OFF, they are providing download mode which allows you to flash official KitKat and Lollipop .kdz files. Bootstack is ensuring SIM support so you could make calls, send texts and access mobile internet. Those files also allows you to fix your bricked phone after flashing bad ROM. Bootstack is basically making you phone work. If those files get corrupted you may have to send your phone to repair.

YOU SHOULD NOT MESS AROUND WITH DOES FILES !!!

Bootstacks available in download section are meant for advanced users who know what they are doing.

Which BOOTSTACK do I need ?

Usually you do NOT need and should NOT touch those files.

They are being updated when you flash .kdz file.

When you're updating your G2 Mini to Lollipop using .kdz you are also updating bootstack to a newer version. After that update you can only use stock LG Lollipop. So if you want to go back to stock KitKat or install any customROM you have to downgrade your bootstack.

You can do this in two ways:

1. Use .kdz file with KitKat in LG Mobile Support Tool. After that update you may lose all your data, your bootloader will be locked, your recovery will be restored to original and you will lose ROOT privileges. Your entire phone will be restored to factory state.

(Safer and recommended for inexperience users)

2. Use bootstack zips provided here. After flashing one of the zip available below you will downgrade or upgrade your bootstack (depending on which zip will you use). You will get unlocked bootloader and your recovery will change to TWRP. ROOT privileges will NOT be affected.

If you decide to use second option check out this description:

- If you want to use official LG stock Lollipop choose Lollipop zip

- If you want to use official LG stock KitKat or customROM choose KitKat zip.

I still don't understand what is BOOTSTACK for

If you updated your stock software from KitKat to Lollipop using .kdz file (or official OTA) you also (unwillingly) updated your BOOTSTACK to Lollipop version which is good. It's how it supposed to be. But if you decide to restore your KitKat backup from recovery or install customROM while being on stock Lollipop you will NOT be able to make calls, send texts or access mobile internet. To have SIM support you need KitKat BOOTSTACK and you can find it in this thread. Read again "Which BOOTSTACK do I need ?" to make sure you know what you are doing. If you have never updated your phone to official stock Lollipop from LG you don't need to change anything.

If you still have questions about BOOTSTACK ask them in Q&A section here:

NONE

You will need ROOT, unlocked bootloader and custom recovery (TWRP recommended) to flash this.

If you decide to use my bootstacks, please let me know if it worked correctly for you (please include variant number and name of zip you used) !!!
