The package deletes itself. It doesn’t install the feature, it just upgrades your RouterBOOT version. The feature is a part of RouterOS, it can’t be removed.
To disable it, go into the “system RouterBOARD settings” menu.
The .dpk package simply update the onboard BACKUP BIOS to 3.22.
Actually not exist any tool (except the .dpk package) to change onboard BACKUP BIOS.
You can only revert to older MAIN BIOS coping the desired old BIOS file “chipset”_3.2x.fwf
on the file directory and go to system routerboard to upgrade to oldest,
or obviously install older routeros, upgrade the MAIN BIOS with older version and re-install 6.27
set protected-routerboot enabled
set reformat-hold-button=10s
or
set protected-routerboot disabled
my question is about seconds. you have to keep the reset EXACTLY the seconds you have set?
if for example i have set 120s, that mean <120s or >120s is not recoverable?
