XDA Senior Member spyrosk released the toolkit for the Optimus 2x, and it looks to be a pretty handy one. There are a lot of simple features, including built a NFFlash root method, backing up and restoring your internal SD card, extraction of KDZ and AP.bin files, and the LG Update Tool. Its most unique feature, though, is quick partitioning.
Going from Gingerbread to ICS involves more than just a change in Android. It also requires a change in the partition structure of the device. This toolkit lets users change from ICS partitions to Gingerbread partitions and vice versa for easy upgrading or downgrading.
This is definitely a toolkit to try out if you own the Optimus 2X. It’s easy to use, and a few of the features can be really useful to new users and experienced users alike. For additional details, check out the original thread.
