So it think i messed up,
i did a 30-30-30 reset on my 3500L with original firmware and tried to install ddwrt but it told me that the upgrade failed, so i tried openwrt and tomato same thing finally i tied OpenWrt Kamikaze 8.09 which installed but now when i try to upgrade to tomato or anything else i get a connection reset.
when i upload smaller files that are not .chk i gets through that i need a .chk file
any help?
ok after the 3rd 30-30-30 reset it accepted dd-wrt
