Use an XML decryptor tool (like the Huawei Configuration Decrypter) to decode the file. Look for the lines containing UserName="telecomadmin" and copy the decrypted Password . Method 2: Firmware Downgrade / Cross-Flashing
When an ISP provisions the HG8145v5, they flash a custom firmware. You look at the sticker on the bottom, see a username user and a password, and think you have access. You don't.

Flash generic Huawei global firmware to patch security vulnerabilities faster than your ISP does. Prerequisites and Requirements
Disconnect the fiber optic cable (PON cable) from the router. Power cycle the router (turn it off and on).
Log back into the web GUI ( 192.168.100.1 ) using the default superadmin username: telecomadmin and password: admintelecom . Navigate to > Firmware Upgrade .
The Huawei HG8145V5 is a highly capable Gigabit Routing optical network terminal (ONT) used by internet service providers (ISPs) worldwide. However, ISPs routinely lock down the device firmware. This restriction blocks access to advanced networking features like custom DNS settings, port forwarding, and bridging modes.
Run the encrypted hw_ctree.xml file through the decrypter tool to generate a readable plain-text XML file.
Some ISPs lock the ONT to their specific network using custom OMCI/ACS profiles.
