FIXED!!!!

Hay, my tactix delta firmware is on 20.85 and i have battery drain (normal with software 20.42 15 days an now on 20.85 2 days max!!!) also test with 20.85 and 20.50.and 20.51 (test the all and all 2 days max!!)

Can anybody tell me how to do it? i try this with 20.42 over my 20.85 but it's not working:

Installation Instructions

  1. Download and unzip Fenix6xPro_***Beta.zip.
  2. Place the gupdate.gcd file, found in the System_v*** folder, into the \GARMIN folder of the device.
  3. If there is a Sensor Hub_v*** folder, place the gupXXXX.gcd file into the \GARMIN\REMOTESW folder of the device. Please note, not all Beta releases will include an update.
  4. If there is a GPS_v*** folder, place the gupXXXX.gcd (or 006B310700.GCD) file into the \GARMIN\REMOTESW folder of the device. Please note, not all Beta releases will include an update.
  5. If there is a ANT_BLE_BT_v*** folder, place the gupXXXX.gcd file into the \GARMIN\REMOTESW folder of the device. Please note, not all Beta releases will include an update.
  6. Disconnect from your computer and proceed through the update.
  7. If you would like to revert to the last public release software, drop the gupdate.gcd file found in the System_Backdate_v*** folder in the \GARMIN directory NOTE: If you revert to an older version of software, all of your settings will be reset to defaults.

I want back to this version...
