[LG Optimus G Pro] hyelton:
This is a 2 in one Guide!

1.For If you have the International Variant F240S, F240L, E986, E988, E989, ETC to flash back to stock in case of brick of it you just want to be back to the phone was when you first got it:)

2.And also this Same Guide can be used to Flash the Telcel E980h Firmware on the AT&T E980, The Advantage to do that is its more close to stock than the AT&T firmware, No stupid 4G/4G LTE AT&T Data Icons, They will now be 3G/H/4G/LTE the stock icons!, and Tethering should work perfect with no modding. Seems to run a lot smoother and better than the AT&T Firmware as well!

3. This Guide Can now be used to Flash TOT files as I have now included it :)

I`m not responsible for any mess ups! Be sure you back up your EFS to just be safe!, If your flashing what is supposed to be on your phone then you should be fine and wont have too.

I AM AWARE about my links, I`m currently working on my server and it will be back shortly... If your looking for the AT&T E980 KitKat TOT here it is:

Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.

CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.

No need to choose desired language, it automatically change to English as a default setting.

Wait until 100% to complete !

REMEMBER if you get Bootlooping after flashing perform a factory hard reset!
