Huawei E352 modem router dongle +CME ERROR: 1

[magmma2001]

Hi, I have changed the Serial Nr on my modem successfully but when I try to change/REPAIR the IMEI I get an error +CME ERROR: 1
I tried to change it in all possible ways found on the internet with no luck. Can someone please help me out?
I have used the following commands with DC Unlocker version 1.00(12/07/2022)

at^datalock="v2 code"
AT^CIMEI="newimeicode382289"#

The error I get is +CME ERROR: 1 or +CME ERROR: 2

Thanks a lot!
