Hello everyone,I'm experiencing an issue with my RBS750 where it suddenly stopped connecting and the white LED light keeps flashing. Upon powering on, the LED flashes rapidly and then slows down to a fading pattern after about half a minute, continuing to cycle like this indefinitely.I've attempted to flash the firmware using TFTP but failed, following these steps:Power off the device.Hold down the reset button while powering on the device.Keep holding the reset button, and the LED turns amber, indicating a wired connection.However, I'm unable to ping 192.168.1.1, and as soon as I release the reset button, the LED almost immediately reverts to white and continues the flashing cycle, and the wired connection is also lost.I'm wondering if there's any other method I can try to recover from this "bricked" state? Any suggestions or advice would be greatly appreciated.Thank you in advance for your help.

Has FW been updated to same version on all units before this happened? What version of FW is on the system? Does ethernet connecting the one RBS to the back of the RBR help get it an IP address?

The firmware version I was using before the issue occurred was 4.6.14.3, which had been in use for quite some time and was the same version on all devices. When I connected my computer to this RBS using an Ethernet cable, it showed as disconnected. Directly connecting to the RBR also resulted in nothing connected. Only when I continuously held down the reset button did the computer display a connection to an unknown network, but it seemed that the RBS did not have an valid IP address. I have scanned the 192.168.1 segment with a tool and did not find it.

Try 192.168.10.250 on this one RBS with a wired PC connected to the RBS after doing a factory reset by pressing the reset button for 15 seconds then release. Last resort would be a 30-30-30 reset on the RBS. Look this up on the internet to how to do this.

I tried to access using the 192.168.10 network segment, but I couldn't find a router; resetting the router (30-30-30) also seems ineffective, and it keeps looping endlessly. I want to use TTL to solve the problem, but I don't know how to open this device's case- do you know how to disassemble an RBS750?

There maybe hidden screws under the rubber footing that can be peeled back to reveal them.
