Sony Xperia 1 III

The Sony Xperia 1 III is an incredibly well-built, feature-packed smartphone that’s undoubtedly Sony’s best handset to date. It doesn’t quite match the more well-rounded feature sets of its biggest rivals and the price will be far too high for many, but if you’re sold on the Xperia experience you’ll love it.

First of all one important thing – before you start to do anything with your phone, do the backup of your personal data. It is only for your safety in case that something goes wrong or any mistake happens. In that case you can use the backup to restore the data and try to do everything once again. Each tutorial has been done many times to verify its propriety, so just read carefully all instructions and continue step by step.

Sony Xperia 1 III (XQ-BC72) firmware update
a) download and unpack Android 11 for Sony Xperia 1 III

Warning – if you want to make clean installation, you dont need to make any changes. If you want to make only update (without factory reset), you need to remove userdata file from unpacked folder before you continue. If you are making downgrade, your device will be factory reset, make backup first!

b) turn off your phone and connect phone to PC with holding volume down button
