I installed openwrt on my Hootoo HT-TM05, after the reboot I could connect via 192.188.1.1 I was able to turn on the wifi and connect trough wifi. I couldn't forward the wan internet to the wifi so I changed some settings. After doing that I cannot reach the router at all. I try to connect it by cable and there is no connection. The normal reset procedure "failsafe" is also not working and the blue led remains blue .
Thank you for your reply, no I didn't try that. But it is not possible to enter the fail safe mode so I am not able to flash the firmwar again (I tried that)
