for everyone that wants to sync their nexus 4 just edit the build.prop so the app sees the phone as the s4 google edition..

change the
ro.product.model=GT-I9505G
ro.product.manufacturer=samsung

Wow, works great, thanks!

Are there any negative consequences that arise from editing the build prop to show up as a different device?

I've been using method this to sync with my Fitbit Flex and it's worked great, except my camera's autofocus has stopped working.
When I open the camera and push a spot to focus on, it just gives me a red focus symbol. CM's Focal, Camera 360 and Snapchat also won't focus. Has anybody else noticed this?

Phone: Nexus 4
ROM: Stock 4.3 rooted (JWR66Y)
Kernel: Stock

Works perfectly for me also running PA 3.99 on N4.

However, autofocus then stops working in the camera due to the edited build.prop :(

Errors exactly as promised by fitibit.com

I've successfully patched application to masquerade Nexus 4 as GT-I9505G!! So now you can revert your original build.prop :cowboy:

I get exactly the errors described by fitbit.com (under "android device compatibility"):
  • Device stops syncing after 24 hours
  • Battery drains quickly
Tested on a Nexus 4 with CM10.2 nightly (20130926).

So Unfortunately I have to go back to syncing with my PC. Actually even that is not working right now... :eek:

UPDATE:
PC syncing was definitely screwed up and the only solution was to leave the Fitbit Flex sitting around for another day until the battery ran out. On recharging the sync to USB-Dongle worked again (yay!)

After contacting FitBit Support about this they explained how to reset the Flex:
  1. Plug your charging cable into the USB port and insert your tracker into the charging cable.
  2. Insert a paperclip into the small pinhole on the back of the charger.
  3. Press the pinhole for 3-4 seconds.
  4. If you see lights on your Flex, let it charge for a few hours.

I confirm that turning off Background Sync prevented the problem happening again. It's been running for about four days now.

Summary
  • You can use this hack to enable bluetooth syncing between the Nexus 4 and your Fitbit Flex. :D
  • Turn off background-syncing! (Menu ->Devices -> tap on your Flex -> remove checkbox from "Background Syncing"))
  • If your sync stops working and the battery drains extra quickly then reset your Flex as described above

You need to turn background sync off and have it only sync when you open the app

Sent from my GT-I9505G using xda app-developers app

Any reason you can think of why my phone would start the install process for the apk but not allow me to click the actual 'install' button?

sweet, thanks. i've already got 2 usb dongles (work and home), but this will be great when traveling.

any idea how future updates will be handled once Fitbit pushes them out? will those updates screw up this version and take functionality away?

Thanks! Installed on my stock (non-rooted, running 4.3) Nexus 4. Did an initial sync without any issues. Have left background sync on, but will keep an eye on battery etc

    Damn - they completely changed Bluetooth support checking....
    However I spoofed it again :cool:
    PS It should be working on all other Bluetooth 4.0 with LE devices (not only Nexus 4)

    for everyone that wants to sync their nexus 4 just edit the build.prop so the app sees the phone as the s4 google edition..

    change the
    ro.product.model=GT-I9505G
    ro.product.manufacturer=samsung
