Firmware updates were previously unencrypted, meaning that CFW was also unencrypted. | |||
The '''bin''' format is simply the unencrypted firmware update package that overwrites the area after the bootloader on the STM32/STM8 MCU's. | |||
After Ninebot began encrypting firmware updates with [https://en.wikipedia.org/wiki/Tiny_Encryption_Algorithm TEA (Tiny Encryption Algorithm)], apps like XiaoTea and others allowed legacy bin files to be converted to .enc.bin files. | |||
This format was known as [[CFW Encoded Bin Format]]. | |||
