I recently bought a GL-XE3000 running firmware version v4.7.13
I saw the critical problem notification and, without realizing my firmware was already up-to-date (and thus the U-Boot flash was unnecessary as per your note), I proceeded to flash the new U-Boot bootloader for the XE3000.
The U-Boot flash process was successful, and the router is currently running fine with the latest firmware.
My question is: Will there be any potential long-term issues or instability since I performed an unnecessary, but successful, U-Boot flash on an already updated device (v4.7.4+)?
Thank you for your advice.
