This is a short note to share my experience with upgrading to CM12 custom ROM on Redmi 1S. Those who have tried to upgrade and failed just like my earlier quick tries should know that it is as straightforward as it always was, although with a small pre-fix. I had tried some 3-4 upgrades with multiple versions of CM12 with Gapps earlier which resulted in crashes of all sorts of Gapps apps, post installation. The phone was practically unusable. Just CM12 without Gapps wouldn't crash, but that would take away the smartness from the smart phone.
Enough with the blabbering... if you face similar crashes, the fix seems to be simple enough. Just UPGRADE your CWM Recovery to the latest. I had trouble with the latest CWM zip installation also since its threw some "assert()" error. Instead I installed latest version of TWRP.img via fastboot. (I am purposely not mentioning any version since the current latest should suit best).
Having installed TWRP, I just did a clean reinstall, starting with the usual factory reset/ wipe dalvik cache, system, blah, blah, followed by CM12 install and then, Gapps install. That was yesterday, it looks good even today. :)
