  • Big problem Cisco 877 K9

    Hi friends, this is my first post.

    My 877 K9 has been broken after update to a new IOS. Now it only start in "rommon >! and with command "cookie" all are cero 00.

    With command "priv" and pass 0000 I can edit those cookie but I do not know the right values.

    After I change any cookie value I can't go again to "priv" because pass 0000 does not work more.

    So I have a nice 877 K9 full out of order.

    Anybody can help me? or just someone will want to know where I will throw it away

    Thanks in advanced for your help. My best regards.

      Hi Dumber! Thanks a lot for your reply.

      Flash is empty because I have been trying to upload a new IOS, but before saving it to flash, it seems to check it with hardware type comparing to some registers that are in rommon > cookie

      Condition have change, I found a web to calculate the priv password so now I can change rommon > cookie

      So, please, I need a copy of rommon > cookie of any Cisco 877 like:

      -------------------------------------
      rommon 1 > cookie

      cookie:
      01 01 00 04 27 fe 00 ea 3e 00 01 ff 01 ff 00 00
      00 00 00 00 00 00 00 00 4a 41 42 01 02 41 42 43
      44 04 01 00 00 00 00 00 00 ff ff ff 50 04 49 11
      ec 03 ff ff ff ff ff ff ff ff ff ff ff ff ff ff
      ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
      ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
      ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
      ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
      rommon 2 >
      --------------------------------------

      I will copy them to my cookie so when upload a new IOS it will be OK with hardware and other codes.

      I will open a new post asking for a copy of rommon 1 > cookie for Cisco 877

      Thanks for your nice help. Best regards.

              Re: Big problem Cisco 877 K9 - SOLVED - OK

              Hi friends.

              I have solved the rommon cookie problem

              After a new IOS upload, it started in rommon prompt with all priv > cookie set to 00 00 00 00 .......

              Some nice friends send me copy of their cookie and I started to study and try them, but the problem in router 877 is that each hardware has his own cookie and if they are not the right ones there is a cookie check that need to be validated by the starting rom.

              Using data of another routers with some printed code in the PCB and serial numbers in labels of my router together with a big dose of good luck I have again the router# right prompt.

              Thanks a lot to all. My best regards.
