Firmware package for a UTEL A154-B modem, compressed as a 1.80 MB RAR archive. The name does not reveal the firmware version, the flash chip or whether the files are a full dump or an update image, so check the contents after extraction. Firmware like this is used to recover a device with corrupted software, either through the vendor flashing tool or by writing a chip directly with a programmer. Confirm the exact model and hardware version on the device label, and back up the existing firmware before writing anything.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
