I am attempting to install the DD-WRT firmware on my Archer C7 v2. The instructions on this site say to upgrade to 150427 first, but the earliest version listed on the site is the 160616. I tried the hosted firmware package but it gives me the error "Error code: 18005 Upgrade unsuccessfully because the version of the upgraded file was incorrect. Please check the file name". I have confirmed I have a hardware version Archer C7 v2 00000000.
It does specifically use the term "Upgrade" and I currently have 180114 installed. Is that why it will not accept the older firmware so I can start installing DD-WRT? If so how am I supposed to roll back to an older firmware? I haven't been able to find anything.

From recent personal experience with the TP-Link Archer C7 v2, the following worked for me:
Since your router is already running the latest US firmware version, Archer C7(US)_V2_180114, the intermediary step for 'upgrading' to Archer_C7_V2_150427 is unnecessary. Just follow the rest of the installation steps in the guide provided by msoengineer--starting with 'Reset to TP-Link factory defaults', and use the currently latest 'factory-to-ddwrt-US.bin' file available at:
I ended up trying this method before the next post and it worked out. I had to TFTP to the old firmware DD-WRT suggests to start from, and from there I could upgrade to DD-WRT normally. Works like a charm now. Thanks for the help.
