Upgrade FW from FlashSYS v2 r90 (07.02.13)

[olegrz]

Hi, I found old LM2  with LM2 CPU: ARM926EJ-S rev 5 (v5l), FlashSYS v2 r90 (07.02.13) and reset it to factory settings.
It operates normally.
I plan use it in future.
Can I upgrade FW? If YES - give me pls link to FW image.
Thank you in advance. KR Oleg
