Thank you for your answer, problem solved

[gamermic]

You will need to do the following before going into mini-boot (OS6850 6.1.3):

Press any key to stop auto-boot...
(Press any key)
=> printenv
=> setenv bootflags 0x1000
=> boot

Once into miniboot, the procedure is standard.
(remove usertableX, set the flag to 0x0, reboot)

Cheers!

Hello,

I'm trying to reset the password on a OmniSwitch 6648 and after following your steps above, I get to the line of removing the userTable3 file. What if that file isint there? These are all that show when doing a "ll" after going to the cd "network" directory.

Simply remove the "userTable".

Kindly post in the appropriate forum in the future.

Have you try:
Login: admin
Password: switch
after the recovery procedure.
mfg TelluR

[carelink114]

yes, i did.

but the switch still cannot log in....

[gamermic]

Perhaps you may try intercepting the boot-up sequence...
