So I've bought an HTC device for the first time. I did S-Off and unlocked bootloader and rooted as well. Now, there's an OTA available (I have the Asia_India variant), and I wanted to ask just how would I go about updating.
Here's what I've surmised till now:
1. Revert changes to system partition or it will fail to update (I moved some system APKs, but I saved them for such a scenario.)
2. Flash Firmware.zip to get stock recovery back.
3. Install OTA normally from the notification.
However, I'm still not sure what else I'd need to do (unroot, using the option in SuperSU?), so was wondering if someone could help me out. I've made backups in Philz and TWRP recovery both just to be sure.
P.S.: I extracted the firmware.zip file from the OTA, and tried to open it, but it doesn't open in apps like WinRAR. Is that normal, with the file only flashable via fastboot?
