For some reason, the lollipop OTA update for the Asus Nexus 7 2012 did not arrive on my tablet. I decided to take matters into my own hand and started searching for lollipop updates, either stock or custom ROMs. On XDA forums, Freak-SlimLp with Android 5.0.1[F2FS] / OptiPop 5.1.1 Nexus 7 was gaining popularity as a fast, lightweight custom ROM on the latest Android version. I was starting to find the tablet sluggish (running Android 4.4.4 stock) as well and decided to go via the option. F2FS had been suggested to speed up the Nexus 7 tremendously (Antutu scores were reported to bump up from 17k to 21k). I decided to try it out and I wasn’t disappointed.
Update: Instructions updated 31 May 2015.
First up, I had to root the tablet. I used the NexusRootToolkit. This program is easy to use, and let you root your Nexus device, install the latest custom recovery, backup, and more with straight forward easy to follow instructions. Once my tablet is rooted, I backup my apps and games with TitaniumBackup, and transferred them to my thumbdrive via StickMount. I used one of the Micro-USB / USB thumbdrive – accessible with OTG Mount (Stickmount). This was a life saviour, great convenience.
