Required:

Install B2CAppSetup.exe, LG PC Suite IV and related driver.


1. Run LGMobile update

2. Plug your optimus 3d (debug mode on) and wait for the connection

3a. If there is a new version, click on Start upgrading software for lg phone

3b. If you allready have latest version, click on User/Support then emergency mode, insert your IMEI and click on check

4. Wait for download and upgrading (15/20 min)

PS. you will loose root, but you will not loose data, data.img is untouched

PS2. if you got some problems, try again. I've tried few time before have a successfully flash.

What do you mean by 3 tries? What error message were you getting, if any?

Is it possible your model is 925 and not 920?

We need CWM so we can make a backup before trying to mess around in the system

It seems my recovery partition was messed up so again install original rom...
