Unlock_Code = f(IMEI, Product_ID, MD5_Hash)

• IMEI: 15-digit serial number (Dial *#06#).
• Product ID: A 8-digit number unique to Huawei builds (Dial *#*#1357946#*#*).
• Salt: A static string like "Huawei123".

The v3 Fix corrected a byte-order error in the MD5 conversion. If you use the non-fixed v3 calculator on a device with Android 6.0+, you will get an 8-digit code that looks correct but will return the error: "Unlock failed, please use the correct code."
