Downgrade LG Optimus M from 2.2.2 to 2.2.1

should be what you need.

 

check your antivirus, it may be hindering you.
Also you need admin rights, turn off UAC.

 

I wish I can downgrade back to 2.2.1. Everytime I try this method, The part with the bin says (This file path is empty) Even though I have it placed in the slot. Any Ideas?

 

Should I download 7zip or can I use winrar?

 

winrar will handle 7z files.. but if it doesnt work with you.. theres nothing wrong with installing something for more support

 

Your just supposed to point lgnpst to that file, no unzip

 

If I point Lgnst to it it wont take it unless its unzipped to have .bin at the end though.

 

No you have to unzip it. I'm thinking user error or his download is corrupt and he needs to redownload.

 

EDIT posted a link.. but its dead

 

Quick Update: The link that was posted by eatyourowntaco still gives me the error of This file path is empty.

 

I am a total noob, but good at following directions. I tried the LGNPST method, but the "bin" area is greyed out and when I try to load the dll with file>load dll, the resulting popup window is empty.

Any ideas on what I need to do?
