Root Flash Back Optimus One

[ingsoon93]

first of all, i m new to android phone and dont have much knowledge about it...but i would like to learn to explore the android phone

i have upgraded my Lg p500/ Optimus One from v2.2 to v2.3 through Lg Mobile Update...now, i would like to try to root my Lg p500/ Optimus One...
as i know that rooting will cause the warranty to be voided, i would like to ask if i can Flash Back my Lg p500/ Optimus One to v2.2(the original version when i bought it) using Lg Mobile Update?
thanks...

You can't flash it via LG mobile update.... you can flash 2. 2 using kdz update or lgdmp...

in the below link follow the instructions to flash the rom you want...this is lgdmp method search xda forum for kdz updater but this is a safer one...if something happens and it is stuck dont remove battery ..just start the process again

Flash your Rom (kdz) from lgmdp - xda-developers
