Hi
I'm having trouble flashing this router. I've successfully flashed DDWRT and OpenWRT onto Linksys, Asus, Netgear and other makes in the past

This router
Firmware Version
1.0.11 Build 20190726 rel.57101(4555)

Hardware version
Archer C7 v5.0

Model
Archer C7(EU)

I have tried a few firmwares from the betas area

Code:
https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2021/05-30-2021-r46816/tplink_archer-c7-v5/

https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2021/05-28-2021-r46788/tplink_archer-c7-v5/



and every one the router says "Invalid file type"

What should I try next? Are there safe/detailed tftp instructions for this router as I wouldn't want to brick it.

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.

Don't know why you hijacked a thread and then opened a new one. Please refer to the forum rules and guidelines. Multiple posts about the same thing is a no-no.

I tried your links and both say "invalid file type"
Another message appears very briefly but too fast to capture or read.

Is there anything else I can try?

Are there region specific firmwares available to download or is there a way to patch a US firmware to become an EU one?

I don't think I did. I replied to a user with a similar but not identical issue to myself.

and then posted a thread starter with full detail of my issue. I searched the forum and only found one hit for "1.0.11 Build 20190726" but he didn't supply much background.

I tried to delete my reply to him, but the thread is now locked.

I'll wait patiently for help to my question hopefully from someone who actually has a C7(EU) and solved the problem.

I don't know why these links seem so familiar to me, but maybe they'll be of some help, maybe not:
