I am currently running DD-WRT v24-sp2 (03/25/13) std - build 21061
I have been unable to telnet (won't accept username and password), putty (won't connect me). I have everything enabled and configured in the web interface, but no luck!
so i figured i should upgrade to a newer version. After downloading the newer build, i go to the web interface and browse to the file and upgrade.... it goes for about 3-5 seconds says its successful and reboots, but i am still at the same build. no errors or anything....I am uploading the file using a wired connection....
I can't connect to the device any other way than the web interface, even though i have ssh and telnet enabled. Like i said, telnet prompts me for a username and password but the one i use to log into the web interface with does not work....
Well I tried that with the same results, I don't think its an issue with the firmware. When I go to update the firmware, I select the correct file and then click upgrade. I get the countdown timer of 300 seconds, and literally 3 seconds goes by and it says upgrade complete and the router reboots... but it never upgrades......

if you try to flash 21061 again does it accept it or do the same thing? _________________ [QUALCOMM ATHEROS] TP-LINK TL-WDR4900 v1.3 --> DD-WRT v24-sp2 (08/31/14) std - build 24952 (private test build)

Did you upload the BIN file to /tmp and tried flashing in SSH?
I had the same issue on my WDR3600 and i resolved the issue by doing this.
1. You will have to flash via WinScp and before enable the ssh daemon (service)? If not, SSH administration will be greyed out and disabled. You need to enable both the service and the administration.
2. Upload the web revert (dd-wrt to stock)file using Winscp in the /tmp folder of your router.
3. Connect with Putty and give this commands:
mtd -r write xxx.bin linux
[b]Every command at once hitting Enter.[/b]
Wait for the flashing to complete then restart and reset to factory defaults.
Well I wanted to give an update, in case someone else has this issue. I couldn't downgrade, couldn't even upload files via WinSCP, couldn't ssh, could only telnet. So I put the firmware on a usb drive and plugged it in. used telnet to get to the usb drive and ran the mtd -r write xxx.bin Linux command and everything worked great!
