I am from india too! Installed using pc companion. Enable usb debugging and unknown sources. Root using easy root tool. Then, for recovery, install the latest xzdualrecovery (as of writing this post, the latest beta version is 2.7.130).
Also, if you are interested in de-odex, check out this thread by @ryokon. Works like a charm! No need to download 400+mb flashable zip. You can create your own by the method shown in the thread.
And,4k & timeshift port as well as smart call handling port works fine. If anybody wants the modded settings.apk for the smart call handling, feel free to pm me!
