ANE-L22 dump file is in fact a complete backup of all data inside the hard drive (emmc), which includes user data, Imei network, security files, etc.
The ANE-L22 dump file contains three main files
rom1
rom2
rom3

These three files are backed up entirely from a healthy ANE-L22 hard drive, allowing you to easily burn to a ANE-L22 raw hard drive.
The ANE-L22 dump rom1 file has a high volume because it also contains user data.
In addition to these original rom1, rom2, rom3 files of Huawei ANE-L22, there is another file with extcsd extension. The task of this file is to perform the ANE-L22 hard drive configuration operation.
