Former Member

My 735XT automatically updated to SW 4.40 (c1055d5).
It sucks!
1) Battery works less time.
2) Watches always trying to find cheststrap HR-monitor, so I have to turn it off from menu.
3) There is no correct translate to Russian language.
...and otger useless things.
I tryied to copy "gupdate.gcd" file in /Garmin folder, but this don't work (as in 210 and 920 watches).
So, I need your help, friends!
How to downgrade software to standard version (3.XX)?
Thaks you!
  • On 2 have you paired it to a HR strap before? If you don't want to use it and presume aren't wearing it, then you can either delete the entry for it in or set the status of it to Off.

    On 3, have you connected to Garmin Connect on a computer. Should be able to get language updates there

    1 - battery does seem to go down a bit quicker. Could be to do with Strava segments. Do you use these? Nice addition if so.

    What are the other useless things?

    As for the downgrade - rarely a good idea but you must then where did you get the gcd file from?

    Hello!
    Yes, I connected my watches to GarminConnect on a computer. There are no translations on the watches of "broadcast heart rate", "training efficiency" and "performance condition" They are translated as "эфеективность тренировки", that means again "training efficiency". So, on the one screen you can see two "training efficiency" with different value.
    Also performance condition is not available in other sports (for example, XC-Skiing). Please, fix it and add in other sports.

    I don't use strava (deleted strava from my watches).

    I downloaded FW3.3 there: http://gawisp.com/perry/forerunner/
    If someone can send me FW-file from another place, please send to [email][email protected][/email]

    About searching HR-monitor, I don't like to go to menu every time and turn it off/on.
    I am using chest-HR every day, but 2-3 hours a day, not 24))) In firmware 3.3 it was good.
    But in 4.40 watches always trying to search and connect to HR: https://vk.com/doc37529207_437975232?hash=ee9ba828be5c1f05d7&dl=34052a53d474451282 if photo from link do not open please tell me

    Watches always trying to find and connect chest-HR monitor.
    I don't want to go to menu every time and turn it Off/On.
    Yes, I am using chest-HR monitor every day, but 2-3 hours a day, not 24 :D
    Make it the same as in 3.30 firmware version please.

    I deleted strava from my watches.

    I connected watches to computer, there are no translations of "broadcast heart rate", "training efficiency".
    Also "performance conditions" translated as "training efficiency" in Russian. So, on the one screen you can see two "training efficiency" with different value.

    Why performance condition is available in swim-bike-run sports only? How to add it in XC-Skiing?

  • Re the HR, suggest trying one of 2 things:

    Power the 735 off and on again.
    If that does not resolve it, then try deleting the current entry for the HR strap in Sensors & Accessories and then try adding it again.

    Don't know about performance condition. This is basically a watch for swim, bike, run. Any other sports seems more of a bonus.

    The normal garmin update procedure on the 735xt does seem to block the device being downgraded - this exact procedure is listed if wanting to try out the latest beta, and it even mentions you can downgrade back again to the latest public release however trying to go to 3.30 from 4.4 doesnt work ive tried it a few times now :(
  • Suggest moving forwards to the latest beta rather than several versions back.
