Popular mobile firmware developers, CyanogenMod team has rolled out the new Android v4.4.4 KitKat CM11 M12 milestone series custom ROM to the Asus' 2013 flagship slate series - Google Nexus 7 (4G-LTE) and Wi-Fi models.
Besides the usual improved customisations options and performance tweaks, the new CM11 M12 firmware comes with a fix for a critical bug – 'POODLE' - vulnerability found in SSL (Secure Socket Layer) v3 protocol, which is used by most Internet browsers incorporated in Android devices.
This vulnerability gave a leeway for network attackers to cause connection failures and trigger the use of SSL 3.0. They exploit this issue to steal sensitive data. [More information, HERE].
Prerequisites (things to remember before installing Custom ROM)
- Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in the future [users can restore warranty by flashing the device with stock-ROM].
- Make sure the device is rooted before going forward for custom ROM installation. [Also read: Root Google Nexus 7 (2013 Edition) with Android 4.4.3 KitKat KTU84L].

- Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/TWRP in the smartphone.
- Users make sure you have installed USB drivers on the PC, or else your device (Google Nexus 7) will not be recognised by the computer.
- Make sure your device has more than 80 percent battery, or else there is a chance of the smartphone getting temporarily bricked if the installation process is interrupted midway.

International Business Times, India Edition, cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked.
