You can interrupt the boot sequence (using a serial TTL adapter) and load firmware via TFTP:

set serverip 192.168.1.100
loadb 0x2000000
tftp 0x2000000 firmware.upd
erase 0x9f000000 +0x400000
cp.b 0x2000000 0x9f000000 0x400000
bootm

Warning: Only for experienced users. Wrong addresses = permanent brick.

The user query mentions "UPD install." In ZTE terminology, .upd is often a file extension used for update packages or configuration files, sometimes utilized in command-line interfaces.

If the standard Web UI does not allow the update, the Maintenance Account (often hidden) may be required.

If your ISP disabled the standard update menu, use the hidden engineering page: zte f670l firmware update upd install

Risk: This bypasses TR-069 checks. If the firmware is not signed for your specific ISP VLAN config, you may lose internet connectivity and need to factory reset via reset button.

Cause: You are trying to flash a V2.0 file on a V3.0 board or vice versa. Fix: Double-check your hardware version. Also ensure the file extension is strictly .upd (not .zip or .rar).

If you don't have a valid .upd file from your ISP or ZTE, do not attempt random updates. Many online "firmware files" are fake or malicious.
