I wanna change Firmwareversion so I can downgrade/update an older Firmware.E.g. my installed Firmwareversion is 2.100.000 and I wanna have 1.100.000. So the updatetool doesn't update because my installed Firmwareversion is higher).Therefore I extracted with binwalk the *.bin-File. But I don't know where this Version-Information normally is stored in Linux embedded systems. Maybe you can give me a hint?This is the first time I wanna disassemble an Firmware so I don't know which steps I should do now. What I found after extraction romfs.cramfs.img is Linux-Standard-Folders with busybox inside. And I can use Telnet to connect to my IP-Intercom.Maybe you can help me to solve my Problem. If you Need more Information I can give you when I'm still at home.Thx forward
