Hello there. I'm working with someone who has an old Cisco Small Business SG300-10MP, and I'm trying to get my hands on all the necessary files to perform a firmware update. The switch hasn't been updated since 2013, currently it's on v1.3.0.62. I'm looking to get it to the newest version, but from looking over old posts on this forum, I need more than what's available in the download center. I need the bootloader, and apparently some 1.3.7 version, which brought a new flash format and needs to be updated to first before the new 1.4.x firmware can be loaded.
I'd appreciate it if someone could point me to where I could download those files, to hopefully keep this 10-year old switch running for another few years : )
