Nah topology yang diperlukan seperti di bawah ini :
- Console
- Compi
- IOS
- Hyperterminal ( Pasti ada kan, ga ada kelaut aja bukkk )
1. Jalanina Hyperterminal di kompi loe langsung de nyalain juga routernya jangan ampe muncul pagar-pagar yang banyak iru, buru-buru de pencet ada yang sebagian break ada yang ctrl break sampe muncul tulisan romon , tapi biasanya kalau emang bawaan routernya nggak ada IOSnya langsung otomatis masuk romon.

2. Nah di command romon, coba ketik confreg nah command ini buat ngubah bud rate biar kecepatan download IOS jadi cepet, coz kalau make default bisa ampe jeggotan baru kelar itu juga kalo ga error xixixixixi
rommon 1 >confreg

3. Nah setelah itu kan reboot nech karena boud ratenya udah berubah tar layer Hyperterminal loe bakal berubah jadi ASCII, jadi cob aloe disconnect dulu tu hyperteminal buat ngeganti jadi baudrate yang tadi loe ubah.
4. Nah sekarang baru lo bisa aktifin perintah xmodem buat ngedownload IOS baru.

rommon 1 >xmodem -?
xmodem: illegal option -- ?

-c CRC-16

5. Dari menubar Hyperterminal, select Transfer > Send dan tentukan lokasi penyimpanan IOS dan select protocol xmodem sambil ngejalanin step 2 dan 4.
6. Nah kalau udah OK bakal muncul pesan:
Erasing flash at 0x60fc0000
program flash location 0x60990000
Download Complete!
Nah sekarang IOS udah masuk ke memori router sekarang tinggal mastiin confreg sesuai dengan confreg yang seharusnya yaitu 0x2102 dan jangan lupa baud ratenya balikin ke degfault ya bukkk…. OK Happy tryin
rommon 12 > confreg 0x2102
