Faster SHA256 checks: Verification of large .sin files is noticeably quicker.
Better USB timeout handling: Reduces the dreaded "Device enumeration failed" error that required unplugging the cable mid-flash.

Solution: Your firmware folder is missing necessary files. Re-download using XperiFirm and ensure you have extracted all .sin files into the NewFlasher folder.

If you have a 2023-2024 Xperia (1 V, 5 V, 1 VI): You must use v20. Older versions will fail to flash Android 14/15 firmware.
If you are a new user: Start with v20. Do not use older guides that link to v15.
