How do I stop automatic updates / MAJOR DRAIN (100% batt drain in a haf day and freezing software FW 25.00)

Hello,

I dont even wanna rant about garmin and FW 25.00 (but I will anyways). I think its the last nail in the coffin for me...

after update my watches started to:

  • freeze (i.e. I went to start activity and it took 40sec to get to choose activity menu...). 
  • battery drained through the night completely - charged 100% in the evening (woke up with watch off)

I tried reboot, hard reboot, hard reset, factory reset, delete all activities...Accodring to forum posts FW 25.00 is major disaster for everybody... how could they release something like that. Its just plain unusable...

Anyways, I painstakingly managed to rollback to FW 24.10. But the watch is always prompting me that I have 30 seconds to cancel automatic update to 25.00 wthich I dont even want to hear about!

How do I stop this automatic updates for good?
