I have not had this problem. The only problem I had was solved by the vendor changing the box for ct1642 chip failure, otherwise the operation of the box is very satisfactory, in the absence of improvements in the firmware that we have communicated in other messages.
Unless the moderator corrects me, I do not advise any update of the ones that appear in the FTP, for me the best version is still that of 01/24/2018.
I remind you that you have yet to respond to this message: viewtopic.php?f=27&t=493&p=1931&sid=fee ... 6dee#p1931
Thank you very much and I repeat that in general it is a big box with no fixes in the firmware.
