I've try to help a friend today to install cyanogen Rom on his LG Optimus 3D.
Here is the method I used :
1. I've Rooted it with a all in one tool.
2. I've install the recovery WorkclockMod
3. Install Cyanogen Rom 7.2
Now the phone don't have network. I've try to follow the tutorial on the forum to try to install the KDZ with the software of Marvin(UpTestEx_mod2_marvin.exe) and nothing work. I really don't know what to do. The phone is no detected on the update.
Somebody can help me? Thanks you so much!
