As I want to return to OEM-Firmware on my Archer C7 v5 - which has now Luci openwrt 19.07.3 (OpenWrt 19.07.3 r11063-85e04e9f46 / LuCI openwrt-19.07 branch git-20.178.63701-ce35d08), I tried to "update" via Luci Webinterface (System - Backup/Flash Firmware - Flash Image).
I have downloaded the newest firmware from tp-link, which gave me Archer C7(EU)_V5 200628.zip; I extracted Archer C7(EU)_V5 200628.bin and tried to flash this file.
It gets uploaded and then Luci tells me that "the uploaded file does not contain a supported format" - pls see attached screenshot.
I am very afraid of bricking the Router and my family will kill me if I do so
Is this normal and can I savely check "force upgrade" and press "continue"?
Do you know that this bin-file will savely work with the TFTP-method?
Or do I have to use a specific (old) firmware version from tp-link?
Or would it work via SSH and sysupgrade?
Did anyone ever did a downgrade to OEM successfully with the Luci webinterface?
Thanks for your reply!
Surely I have read this (and many other postings) before.
Do you know that the bin-file Archer C7(EU)_V5 200628.bin will savely work with the TFTP-method?
Or do I have to use a specific (old) firmware version from tp-link?
When you used the TFTP-method: did you use the OEM-image which was downloadable at this moment at the vendors homepage or did you use an old or special one?
Sorry for all the (maybe dumb) questions, but I am really afraid of bricking the router and leave my girls without internet.
