The OnePlus One is one of the first ever flagship devices to feature Cyanogen Mod 11 as the main OS. It was released about a month ago. This device has seen an extremely limited release, but has been so popular that its exclusive CM11S rom has been ported to other devices. If you were one of the lucky few to have either won one of these devices or one of the few who were invited to purchase one you may be ready to run a new rom. Thanks to Team Win Recovery Project you will be able to flash new roms at will! They released their official recovery for the OnePlus One today!
