First see my other video about huawei e5573s unlock and downgrade which is somehow related to it , how to Downgrade firmware on E5573s and E8372h ..
—————————————————————————-
Procedure of Unlocking is simple and for all of these given below huawei model and have been tested successfully …
Huawei E8372h-153
Huawei E8372h-608
Huawei E5573s-320
Huawei E5573s-606
Huawei E3372h
Huawei B310s-927
step1:- you downgrade firmware to version# 21.xxx.99.xx.xx
step2:- you use my new Huawei Unlock calculator from here https://youtu.be/q1QpgUpbSzM
step3:- you upgrade firmware to anyone that is suitable to your modem .. and thats it , now can use any non carrier sim in your modem device
but if you are unable to follow the above mentioned 3 steps then it means you are either stuck on upgraded firmware or in anyway your modem device unable to Unlock easily thats why you use Emergency Bootloader method or injection method , thats why i made these videos . and also injection method can also be used if you stuck with modem device not responding or you think is near to death ..

Note:-
Do not use my old calculator, it hangs and freezes, I’ve just uploaded a new calculator, and he immediately unlock with a single release button,no need to calculate 8-digit unlock code Nck Network. https://youtu.be/q1QpgUpbSzM

in this video i used original huawei usbloader thats why important info like imei# and serial# and webui dashboard , all are wiped out, but later we got successs by restoring back all of these imei# and serial# and dashboard webui , you can see all of these in the video ..
so my suggestion is to use usblsafe instead of usbloader.bin ,

you should watch below video on how to insert webui , zong webui for e8372h is already uploaded to firmware folder .

How to restore serial#
let suppose your modem device serial number is J5HBYA93C3042173 , so convert this in to hexadecimal value which is 4a 35 48 42 59 41 39 33 43 33 30 34 32 31 37 33.
J5HBYA93C3042173
4a 35 48 42 59 41 39 33 43 33 30 34 32 31 37 33
e.g:- hex value of J is equal to 4A .
AT^DATALOCK=”unlock code”
AT^NVWR=6,20,4A 35 48 42 59 41 39 33 43 33 30 34 32 31 37 33 FF FF FF FF
