Though seemingly overshadowed by its more-powerful predecessor, there’s no stopping the Asus Eee Pad Transformer TF101 from getting more Ice Cream Sandwich love in the form of the CyanogenMod 9 (CM9) with Cornerstone custom ROM.

The new CM9 with Cornerstone ROM promises jampacked features of Ice Cream Sandwich with a slightly added flavor in the form of the Cornerstone Android modification integrated into the ROM.

Cornerstone is a great modification feature that lets users multitask, as it helps in switching between applications and closing the other before opening a new one. The Cornerstone modification utilizes the extra screen space found on many Android tablets to let users get a glimpse of 3 different applications running in the background by letting them switch between the running apps just by selecting them.

Since this ROM is based on CM9, the developer notes that all bugs from CM9 have been inherited by the ROM, except the issue with the Wi-Fi MAC address.

Read on to learn how to flash CyanogenMod 9 with Cornerstone custom ROM to your Asus Eee Pad Transformer TF101.
