Ok, i have searched this forum and too many posts with nothing to do with my question are returned. With that being said, I just purchased a TP-Link Archer C7 that is v5.0 with firmware version 1.0.11 Build 20190726. I go to System Tools ... Firmware Upgrade ... Manual Upgrade and browse to the New Firmware File: factory-to-ddwrt.bin from the router database for TP-Link Archer C7 (AC1750) 4.x
When I hit Upgrade, I am returned with "Invalid File"
I am now at a loss.. how did everyone else with the C7 v5.0 get DD-WRT on theirs?

You got bit by the not-up-to-date router database. The last two links are the last two releases from this week, today and two days ago. You can't flash the v4 file to a v5.

DISCLAIMER

This database may not have up-to-date information and may even recommend a build which might cause issues. As such, you should check the device specific forum (Broadcom, Atheros, MediaTek, etc.) first before flashing any build recommended in this database. There you will find build specific topics that discuss any issues with a particular build/release. For more up-to-date firmware files, please visit the firmware faq.

Did you get an answer to this?
I have the same build
I have tried the latest beta for my model
from
https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2021/05-30-2021-r46816/tplink_archer-c7-v5/

but this does not work either.

Try downgrading to one of the older stock firmware files from 2018, preferably the oldest. It may be that you have to convert EU to US.

Your stock firmware may be locked. The problem with the OP here is they were using the wrong factory-to-ddwrt file for a v4, which you cannot do.
