Update China Galaxy S7 G9300 to ZCU2CRF5 Android 8.0 Oreo Firmware

Finally, users who own the Chinese variant Galaxy S7 G9300 can now update their smartphones to official Android 8.0 Oreo update. Samsung’s older flagship is receiving its second major Android version upgrade. With new Samsung Experience UI, multiple feature additions, ZCU2CRF5 Android 8.0 Oreo can be easily classed as a substantial upgrade. Previously, the only route to update Galaxy S7 to Oreo was to install custom ROMs. These ROMs, however, missed out on propitiatory functionality such as Samsung services and also were not as reliable as official firmware. Fortunately enough, the official update is finally out and users can manually install ZCU2CR5 Android 8.0 Oreo with the steps ahead.

For any substantial upgrade, it is recommended that you factory reset your phone and start fresh. What this will do is, delete any older junk that your system had accumulated, giving you performance boost and space savings. Before actually reset-ing, you can either utilize Samsung Smart Switch to create a backup of all data or you can consult our detailed tips for how to backup all your stuff and all your apps. After you have made sure that your data has been safely and completely backed up, install ZCU2CRF5 Android 8.0 Oreo on Galaxy S7 G9300 using ODIN with the instructions ahead.
