Our verdict
Syrotech makes the GPON ONTs and OLTs used by many Indian fibre ISPs and cable operators. Its firmware page is a table of type, model, hardware version, firmware version and default login, with no login needed; some files are offered on request by email. Syrotech's own instruction is to install only firmware that matches your exact model and hardware version. OLT upgrades affect every subscriber behind them, so schedule a maintenance window. Before flashing: back up the current configuration, match the exact model AND hardware version printed on the label, and never load firmware made for a different model or region. Use a wired connection and do not cut power during the upgrade. Take firmware only from the vendor's own portal — not from YouTube links, Telegram groups or mirror sites.
