When you try to flash the full rom it says “cant open the zip file” and/or “cant access the sd-ext”:
Confirm problem installing full ROM v2.1.1. Can’t install in TWRP or CWM. TWRP say file corrupted in CWM (bad).
2.1.0 full ROM Installation works fine so until 2.1.1 full ROM is fixed, download 2.1.0 and install 2.1.0 to 2.1.1 OTA.
