Hi. Bear with me, first post to the forum and all, wanted to say a couple of things:
First a massive thanks to @chrmhoffmann for making android 4.4 on fairphone a reality, I can’t imagine the time you’ve put in to this. Secondly thanks very much to anyone who contributed to this excellent guide. II’d installed custom ROMs on previous phones but having felt no need to with my fairphone up to now I really had forgotten how to do most things.
The update mostly went really smoothly, although I did get the problem with the phone being stuck between the “android” and “loading” screens. Had to use the buttons to turn it off and boot into recovery as I couldn’t get it to do so with adb, but once I did and wiped data all worked alright. Really impressed with the boot time and android 4.4 does feel that little bit snappier. The only problem I’m having still though is kind of to do with why I upgraded - the bluetooth.
I got a fitness tracker band from my fiancee’s family for Christmas which required bluetooth LE. A quick google told me the fairphone hardware would support it but not the software currently, hence the sudden interest in updating. Unfortunately despite the update I still can’t get this to work.
The particulars: I’m trying to connect to a Jawbone UP24. As the instructions say to do I start their app, follow the steps to turn the band on and then try to get it to pair with my phone. It always times out and tells me the device can not be found regardless of soft resets, app restarts, phone reboots etc. This sounds very similar to the problem Pete was having with his Garmin watch. Unfortunately while I can see the device in settings/bluetooth I can’t seem to pair with it - I either get an incorrect PIN message or else the bluetooth appears to reset itself when attempting to do so.
Not sure if there will be much anyone can do to help me out with this, but thought I would make sure I mention the problem for the sake of ongoing development anyway. Many thanks again, and Happy Christmas.
