Hello to all.
I am sorry, but I am completely new to this. I have had a look around the forum to the best of my ability but can’t locate what I need.
I have a TP-Link Archer C9v1 and have installed what I believe to be the correct firmware update, factory-to-ddwrt.bin. The upgrade went well (or as expected) and it completed correctly. I have subsequently made an error with the username and password (possibly caused by me not doing a 30/30/30 reset at the beginning and cannot enter past the first page of the GUI.
I can access 192.168.1.1 and in the top corner it says:
Firmware: DD-WRT v3.0-r40634 std (08/14/19)
Time: 16:08:22 up 5 min, load average: 0.00, 0.03, 0.00
WAN IP: 192.168.0.113
If I try to go to any tab it asks for the username and password. I am unable to pass this point. The standard reset for the Archer C9 appears to be pressing the reset/wps key for around 6 seconds and it should work. This does nothing. I have then tried the 30/30/30 reset as instructed maintaining the same reset/wps button depressed for 30 sec whilst on continued for 30 secs unplugged and then a further 30 secs when powered back up. Unfortunately this doesn’t do anything. I am able to return to the initial web gui page but the standard username and password does not give me access. I have tried root as a username and admin as the password; also a blank username and pretty much anything else I could think of
Does anyone know of another way to “break” in to the Archer C9 v1 or to simply reset it?

I really appreciate you taking the time to reply so quickly. following your first link for the v1 router it says to perform the 30/30/30 reset.
It seems clear that the firmware has installed I just can't get into anything other than the first page and I don't know of any other way to reset the router.
I have tried the various combinations of username and password.
I have also tried the reset/wps button holding for 10 seconds and much longer too. It appears not to have any effect.
I am hoping that someone may be able to make another suggestion as to how to reset the router so that I can progress a little.
Thanks again for your help

Which is totally wrong, you do not do a 30-30-30 on a Broadcom ARM router, otherwise you risk bricking it. Do you remember what your old user/password was? Or did you completely forget what you set them to? I'm kind of out of ideas outside of tftp flashing the oem factory firmware and trying to convert to DD-WRT again. I will look and see if I can find any reports of the reset button being broken on that router...
Thanks again for taking the trouble to reply. I will try the tftp flashing method. I have tried my old passwords etc. without success. Just a bit frustrated at the moment. I do appreciate your time and will let you know if I'm successful or not.
Many thanks
Hi Again, Sorry to keep coming back!
I started the tftp route, but got thwarted as the router won't go into recovery mode as that is the mode you get by pressing the reset button.
The most frustrating thing is that the router is actually working in that my pc is connected to it and it is then passing on to the modem gateway. It seems to ignore all external physical buttons (you can't turn off the WIFI either using he wifi on/off button).
If you think of anything you believe may be helpful I'd be very grateful, but please don't waste too much of your time; I don't wish to be a burden.
Thank you
There are a lot of posts saying to 30-30-30, but AFAIK, you aren't supposed to do that on a Broadcom ARM device or you risk bricking it. Maybe this is an exception, but if it's not working to reset it and the reset button doesn't work....
Many thanks; I'll have a look.If I don't have any luck then I have a router heading off to router heaven!
I really appreciate all your effort and have my fingers crossed. I'll let you know if I have any luck.
I have tried the 30/30/30 reset, but as far as I can tell it is not actually doing anything at all as the reset button is completely ignored. It's as if it's not there. Unfortunately pretty much everything I've tried so far involves the reset button being functional.
Cheers for now, Carl

I stumbled across this ticket. Did you set a wi-fi password? It could be that this issue is still a problem... of course, the device in the ticket *is* Atheros, but nothing would surprise me.
Maybe I missed this but are you able to telnet into the router?
User will always be root, Password could be what you set or admin or....
As far as 30-30-30 goes:

For OEM f/w, but not in DD which requires 10s to reset. If you really already tried a 30-30-30 though this should have already happened. You have held the reset button for 30s w/ DD running? But ya, try telnet; I've had the GUI block access before while telnet still works. Then you can clear the password via nvram, or (better) just `nvram erase && reboot`.

Welcome to the party, bushant and jwh7.... I am hoping this doesn't have anything to do with the driver issue crashing things on ARM, if I was following the commits right.
Lol; tru dat. I have a C8, still on OEM. The OEM WDS works very well; connects to other chipsets in open mode no problem. My neighbors (on fiber) and I (cable) have an agreement to share each others internet in the case the others ISP goes down. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#
