DIR-300 on 1.5.8 - can't downgrade/upgrade

Hi All,

I've flashed my DIR-300 with the 1.5.8 and (obviously) it's not running it very well. In fact it's not stable at all. So I wanted to downgrade it to 1.4.7 (which has been quite good). However GUI upgrade doesn't work, I can't access the Bootloader, also TFTP doesn't work.

I did some research and from here:
http://www.gargoyle-router.com/phpbb/vi ... f=8&t=3454
I know that I'm unable to flash it because of the low RAM.
I have also tried to ssh the router, stop all the services I knew I can, downloading the image by wget and then doing manual upgrade (sysupgrade) but it's just rebooting.

Can't also access the bootloader so tried this:
viewtopic.php?f=5&t=492
Telnet is available but still no success.

I've been also trying the TFTP without success.

The samllest *.combined.squashfs.img I've found is the OpenWRT 8.0.9.2 (arround 2,4MB).

Does anyone habe any idea howcould I downgrade this reouter andmake it usefull again? Serial perhaps? I do have the FTDI USB<=>UART adapter...

Thanks for any advice!
Greg

I'm sorry, but I'm not geting your point. I've tried all besides serial connection. Does it mean this should help access the RedBoot?

Looking forward
Greg

all options are listed there

serial cable will most likely fix your problem

Serial did worked for me! :)
I've broken my ftdi converter in the meantime and managed to fix it as well, however one info I'd like to leave here for the others:
when you're connecting to the router using serial you also need to have lan connected (for TFTP to work).

Thanks!
