I believe I have the legacy RUT950 - the one with the old design (HW rev 0202). It has the huawei ME909u-521 LTE module.
This unit stopped working the other day having previously worked fine. It appears now to be stuck in bootloader mode. I can access both the firmware and the uboot pages via the fixed IP 192.168.1.1
I attempted to install various versions of the firmware to restore the unit and everything appears to go through the process - no errors are shown, but after various patterns of LAN lights it just reboots back into bootloader mode with the 4 LAN ports rapidly flashing at the same time.
I could not locate a download for uboot so wasn't able to verify if replacing the bootloader file would help?
Any advice gratefully received.
