I’ve decided to upgrade firmware on my old Linksys WRT54GL (v1.1) . I’ve migrated from Tomato v1.23 to DD-WRT v3.0-r40559 .
Before migration I’ve reset the settings of the router (using Tomato admin console) but haven’t returned to the original Linksys firmware.
It’s because I wasn’t sure whether it was still possible, I recalled vaguely that when I moved to Tomato I used an option of completely wipe original firmware from the device due to memory limitations.
As it turns out that was a mistake. Flashing went fine, I was able to get to the setup screen of DD-WRT firmware and create router name, admin login and password. However when I try to access any tabs in the admin console I’m getting a prompt to provide user name and password screenshot
I’ve learned after the fact from this thread that the problem is caused by a different encryption method used by Tomato vs Linksys/DD-WRT.
I’ve tried the 30/30/30 reset but unfortunately it doesn’t solve the problem. I went through the thread on Recovering from a bad flash I’ve also read this thread where Keiichi25 specified some steps on wiping the NVRAM of an inaccessible router.
I’m wondering though whether anyone has run into this particular issue before?
Do you have some suggestions before I go ahead with the nuclear option and try to recover the stock firmware via TFTP?
