- Device: ZTE F601 V9
- Firmware: 9.0.10.P1N9
- Access: Telnet enabled
What I did:
- Dumped all MTD partitions (mtd0–mtd6)
- Searched full flash for:
- ASCII SN (ZTEGxxxx)
- HEX values
- Partial matches
Result:
- SN not found anywhere in flash
Question:
- Is SN stored in GPON chipset internal memory on this model?
- Any known method to modify it?
Tried:
- Hex editing
- TFTP
- SPI dump
- Factory mode tools
Goal:
- Change GPON SN for ISP authentication
- please help
