How can I root my root LG Optimus 2X running stock ICS? I upgraded my LG O2X to stock ICS. How can I root the device? Superoneclick is not working for the same.
If you've got a computer with Windows running on it, you might want to give the All-in-One Toolkit a try. According to the XDA-Thread linked, you can download it from here or here. Once installed and started, it gives you a simple interface to select actions from, including


rooting the device
install a custom Recovery
backup/restore partitions
flash ROMs and bootloader


and more. If I read the description correctly, the toolkit should work for Gingerbread and Ice Cream Sandwhich.
