PS: Do not flash partial update OTAs (under 1 GB) on a modified device! If you want to use partial OTAs, you must first flash a full OTA that it applies to, and then flash the partial OTA from stock recovery. Flashing partial OTAs from TWRP will either fail or soft brick your device. You can return to a usable state by flashing one of the above full OTA zips in recovery.
