If you are looking to upgrade, downgrade, or reflash your SR120-A, you will quickly hit a wall. FiberHome does not host these files publicly for consumers. Here is the reality of SR120-A firmware hunting:
Before downloading any firmware, you must check the sticker on the bottom of the router. The FiberHome SR120-A has at least three distinct internal hardware versions. Using the wrong file will cause a "wrong image" error or a brick.
Look for the following identifiers:
| Hardware Rev | Chipset | Flash Size | Common Firmware Type | | --- | --- | --- | --- | | V1.0 | MediaTek MT7621AT | 16MB | FiberHome proprietary (UBI format) | | V2.0 | Realtek RTL8197F | 128MB NAND | OpenWrt compatible (factory.bin) | | V3.0 | Broadcom BCM6750 | 256MB | CFE-based (.trx) |
Do not proceed without this revision number. When in doubt, open the router’s admin panel (usually 192.168.1.1) and check Status > System Information for the "Hardware Version" field.
If the web interface is inaccessible (white screen of death), use the bootloader’s TFTP recovery.
