My GL E750 does not boot anymore since a few days. It displays booting progress on LED up to about 80% and then stays there forever. No proposed reset does help. The behaviour is always the same: booting up up to 80% and then hanging. debricking with uboot was also not possible. Is there any possibility to monitor the boot up process or turn off some parts to boot up essential parts? or connect via some more low level terminal since ssh connection is not possible at current level of booting? thx in advance luzi ---

Maybe you can try reset MCU. > [@MCU firmware](https://forum.gl-inet.com/t/mcu-firmware/22911/8): > > There is a second reset button. There is a MCU reset pin near it on PCB. Anyone knows something about it? ---

Already tried it and same result that starts booting and hangs at about 80%. Is there no possibility to connect to device and monitor booting? ---

Have you tried to upgrade different firmware versions in the uboot? ---

I noticed some mistakes in the description of the document, and I have fed back to my colleagues. First, Connect the router to the PC using a network cable. Then set the IP address of the PC to 192.168.1.2, the netmask to 255.255.255.0, and the gateway to 192.168.1.1. Finally, repower the router and hold the reset button. About 10 seconds later, the screen will display uboot mode. You can upgrade the firmware by typing 192.168.1.1 in your browser. ---
