Installation
Tested: TP-Link Archer C8 V1 with TP-Link firmware: Archer C8_V1_150515
- Download DD-WRT firmware: factory-to-ddwrt.bin
- "Reset to factory defaults" via the OEM Archer GUI.
- Also from the Archer GUI, upload the factory-to-ddwrt.bin file.
- Wait at least one minute
- Access DD-WRT GUI at 192.168.1.1, set password, then GUI reset (Admin->Factory Defaults) again
- v2 should use the same process, and the 'v1' file.
- 33006 has also been tested.
- v3 is an EU model. There is one report of a v3 running DD-WRT, but with no details.
- No reports of a v4 (also EU). Warning: v4 has different flash size from v1-3.

Recovery Mode
The v3 and v4 CFE has a built-in Webpage Firmware Recovery mode for bricked routers: see TP-Link article.
It may be possible to retrofit a v3 CFE onto v1/v2 models, but this is untested.
