I have been trying to upgrade the firmware of my unit, but it does not work.
Actual fw version is 188.8.131.52 and I am trying to upgrade to 184.108.40.206.
HW version is V1.5A.
I am using your GSUpgradeTool and files from Release_GDS3710_220.127.116.11_for_GDS3710_v1_0_2_x_or_lower.
I always get the following message:
04/18/2019-14:45:33 - Device upgrade and reboot in progress. It may take some time (about 2 minutes). Please be patient and do not shutdown the program.
After several minutes nothing is happening and no indication of data up/dn is shown, always 0 B/s.
