Hi m8 download this and follow the tutorial. :proud:

Good luck. :). My 4100 Dloading at 1.1MB/s :banana:
 
@notmeatall3

is that tutorial just for changing the mac or actually hacking the firmware? didn't see any mention of the serial cable..

cheers
 
thanks mate

can't find that Boot.exe program though??

cheers
 
Try this one ,, if you find it wont start due to it missing some winsck.ocx file ,just google it and install the missing file .

Regards
 
thanks again m8

I'm starting to think that this 4200i is knackered!!

fireball doesn't give a lot of info and when using Netboot all I get is

"sending reset request...error"

what do you think?

cheers
 
What do you get in the hyperterminal window ?? Are you able to stop the boot process??

Regards
 
well..yes and no..first time I could stop it then second time it just kept running!!
 
Make sure echo-mode is enabled ,if you still have problems try with terraterm ,, when you have boot.exe running in the background and it has the vxWorks file in it`s directory, the minute you insert the bootline , it will load the the file through boot.exe.

OK..got the bootfile goin..pasted the 2 lines of text into hyper..the tut says I got to write the new firmware to flash!! I've got the hex file but I don't know what to do with it?

cheers
 
Ok if the vx file took ,you have to goto http://192.168.100.1/ straight away before the modem reboots as the vx file is temporary ,,on this page you should find the hack tab ,click on that and scroll down to the bit were it says upgrade firmware and load the hex bin then update ,,you should see the modem reboot within a few minutes and after that you should have permanent hackware on the modem.

Regards
 
Well if you have loaded the vx file , it would of had to have loaded through hyperterminal ,,so if you look at the images in the tut , and they are similar to what is on your terminal and fireball windows then the file took ,then just goto the 192 page of the modem and see if you have the hack tab ,,if so then upgrade.

Regards
 
so it's while hyper is still running?

can I ask if I should have coax and ether cables connected?

thanks for your patience
 
You should have the ethernet cable connected , but not the coax. you must also set your ip to a static one .

Regards
 
got into hyper and got this:

Ok everything on hyperterminal is ok up until the part where it is looking for the vx file ,,make sure boot.exe is running in the background ,and check that it has the correct ip of 192.168.100.10 allocated.
