Use an online Huawei password decoder (search "Huawei XML decrypt") or a local script like huawei-xml-decrypt.py to convert the hash into a plaintext password.

This tells the router to use the Global interface. Next, replace the default configuration file:

(Note: The password will not be visible as you type it.)

Get rid of pre-configured settings that might slow down your connection or restrict access.

Open the ONT Tool on your computer, select your network card, choose the "Normal Mode" or "Upgrade" option, and click .

Before making any changes, back up the original configuration files. This lets you restore your router to its original state if anything goes wrong.

There are two main approaches here.

Navigate to Network Application > TR-069 Application . Uncheck "Enable TR-069" or delete the TR-069 WAN profile entirely. This prevents the ISP from managing your router remotely.

The Huawei EchoLife HG8145V5 is a widely deployed dual-band Gigabit Routing Optical Network Terminal (ONT) used by internet service providers (ISPs) worldwide to deliver fiber-to-the-home (FTTH) connections. While it is a highly capable device featuring dual-band Wi-Fi (2.4GHz and 5GHz) and multiple Gigabit Ethernet ports, ISPs frequently lock these routers with custom firmware. This custom software restricts access to advanced configuration menus, prevents the use of the ONT on alternative network providers, and hides critical performance tweaks.

This comprehensive guide covers the technical methods used to unlock the Huawei HG8145V5, retrieve the superadmin credentials, and configure the ONT for maximum performance. Understanding the Lock: Admin vs. Superadmin

| Issue | Likely Cause | Recommended Solution | | :--- | :--- | :--- | | | The Telnet service is not enabled on the router, often due to an ISP lock. | Re-run the unlocking tool and make sure the shell flashing step completed successfully. | | Login fails with "Login faild, no remote access permission!" | The root account or Telnet access is disabled in the firmware. | Flashing the appropriate shell file should resolve this by re-enabling access. | | Router becomes unresponsive (bricked) | A command was executed incorrectly, or the wrong firmware was used. | Power Off Immediately : Turn off the router and leave it off for 5 minutes. Factory Reset : If it powers on, press and hold the physical Reset button for 30 seconds with a paperclip to restore factory defaults. If this fails, advanced recovery (via JTAG or serial console) is your only option. | | Router doesn't register with ISP after unlocking | The router's serial number or MAC address needs to be registered with your ISP's system. | Contact your ISP. Provide them with the router's MAC address and serial number, and ask them to authorize it on their network. | | Can't access the Global interface | The commands in Step 5 were not entered correctly. | Use Telnet to run the sed commands again, making sure they are typed exactly as shown. |

Many fiber providers (GPON) authenticate devices via the Serial Number (SN) or LOID . Even if you "unlock" the software, the device may not register on a new ISP's network without their explicit authorization. EchoLife EG8145V5 - Huawei Enterprise

shell ls /mnt/jffs2

Unlocking this device generally follows three primary pathways:

Set your computer’s local IP address statically to 192.168.100.2 with a subnet mask of 255.255.255.0 .

cd /mnt/jffs2 cp hw_boardinfo hw_boardinfo.bak cp hw_ctree.xml hw_ctree.xml.bak

Run these commands :
