ISR4331 IOS Version 15.4(3)S6a.

Is isr4300-universalk9.03.15.04.S.155-2.S4-std.SPA.bin actually the same as ISR Software (X86_64_LI​NUX_IOSD-U​NIVERSALK9-M), Version 15.4(3)S6a.

 

I want to download ISR Software (X86_64_LI​NUX_IOSD-U​NIVERSALK9-M), Version 15.4(3)S6a however I can’t find any such version for ISR4331 router in downloads.  Please advise how I will be able to get version 15.4(3)S6a.

15.4(3)6a is already quite old. I would go for isr4400-universalk9.03.13.09.S.154-3.S9-ext.SPA.bin. If you really want the older file, it corresponds to isr4400-universalk9.03.13.06a.S.154-3.S6a-ext.SPA.bin

If you really want this specific old version then contact TAC.
