DO NOT TRY TO UPGRADE WHEN WIFI IS LINKED, IS IMPOSSIBLE.
Kernel Fail when try to install upgrade (any, also branding or downgrade...).
Kernel Fail also when AP disconnect for some reason....
1) Disable AP: NOT the wlan inside SXTsq 5 ac!!! (no version/hardware matter)
2) Reboot SXTsq 5 ac
3) Use winbox to put full (upgrade package, not ALL single package...) routeros package 6.42rc27 ARM or higher
4) Reboot (and now upgrade)
5) Enable AP
