hello everyone, I have successfully installed openwrt 23.05.5 on my FritzBox 3390 router, but now I would like to revert back to the original firmware.
Would it be ok either via factory reset of the router or by installing the original firmware (already downloaded locally).
I'd like to ask you for some help, because I've read through various threads but at the moment I haven't found a solution that works for my router and I would strongly need to go back to the original firmware to get everything working properly again.
p.s: i've already tried with avm recovery tool (although they don't make it specifically for my model): it finds the router ip, but then tells that the firmware is not compatible and I can't continue.
Thank you very much, I hope you can help me
