If it has Gingerbread, I would use a root solution based on ZergRush. Gingerbreak will likely fail. The Sons of Korhal Root Utility *should* do the job but make sure you have all of the appropriate drivers installed first.
I did use or started to use Gingerbread. But waited about 45 minutes and did a panic attempt and quit it. Phone is still working good but I think it stalled. FYI, I am using a Mac to use Gingerbread. I hadn't heard of ZergRush and I will look into it
What drivers are you all using for the Optimus L45C and where do I get them? I downloaded sons of korhal and .Net framework 4 and I couldnt get it to work so I think I have the wrong drivers for the phone. Help please.
Remember the computer has to know the specific phone. It can't say anything generic like cell phone it has to say lg optimus. Then you should be set to go. Look at the tool above in the menu and select find driver (or something similar as I am going by memory)
Ok I have a rom dump from this phone and it has a locked bootloader and 2 mtd mystery parts. Trying to port the cwm recovery from the q.. if someone with better understanding of the mtd part pm me and I will give you the rom dump..
