Sky Vega A850 is Sky’s 2012 flagship device. It is powered by 1.5 GHz quad-core Krait processor and 2 GB of RAM. This device features a 5.3″ Pro LCD screen with 720p resolution. Another notable feature is its 13 MP camera which is quite capable of taking great photos in almost all the situations.

Sky is a South Korean company focusing only the Korean market till now. This phone was released to 3 different carriers in South Korea and thus it came in the form of 3 different variant, A850S, A850K and A850L.

Just like all other Korean phones, this model also comes with the default Korean SMS limitation of 90 characters. Also, you would notice a lot of Korean, carrier-specific bloatware in the menu. For getting rid of all this, you will need to flash a custom ROM of your choice. Keep following the guide below.

Upgrade

As of date, this device is officially at Android 4.1.2. If you are running some older version of Android on your A850, you will need to update to the latest version and then proceed. You can either connect to WiFi and use the built-in software update utility or follow the guide linked below for upgrading your phone to the latest Android version:

Root

Important: Skip this step if you want to flash a custom ROM. This won’t do any harm but it isn’t necessary in that case. If you only want to root your current ROM running on your Sky A850, follow the steps below:

Download CWM-SuperSU.zip from here and copy it to your Phone’s internal storage:
http://adf.ly/w2XuX
Download CWM recovery for A850 from here:
A850_CWM.zip
If not already installed, download and install Sky USB drivers from here:
Sky_USB_Drivers.zip
Go to “Settings > Developer options” on your phone and enable “USB Debugging”.
Connect your phone to any USB port on your PC
Extract the earlier download A850_CWM.zip and run “cwm_jb” batch file.
Wait patiently, you phone will first reboot into Fastboot and then into CWM.
Once you see CWM on your phone, choose the “install zip” option and choose “CWM-SuperSU.zip” you copied earlier to your phone’s internal storage. Confirm the flash on the next screen.
Once CWM-SuperSU.zip is flashed successfully, simply reboot your phone. Congratulations, you are now rooted!
