Request code for Huawei B311-221

[Major0418]

Hi, 
I'm trying to unlock my Huawei B311-221 (
IMEI: 869547049644966) with a-zgsm tool and I got the results:


Code v1: 54775167
Code v2: 42133980 
Code v3 201: 69268594 
Flash code: 58472434


But instead of 8 digit code, it requires a 16 digit code
Anyone can help me? Thank you
