Read here ** you must have Android 4.2 and cm10.1 as your primary ROM** Instructions: http://forum.xda-developers.com/nexu...m-v24-t2472295 ** two alternatives for hackers:*** 1. you can still have Android 4.4 -based secondary ROMs, provided you inject required firmwares (check MultiROM threads)*** 2. you can have Android 4.4 as primary, flash (physically into phone's partition) modem image from 4.2 (0.84 tested OK), and still see things working in SF and CM (tested).

Please stick to either SIM available or not when running Sailfish OS on Nexus 4.** There may be a bug with oFono RIL support that makes it not report IMEI value causing this and will be sorted out in a later update.** DISCLAIMER: Using Jolla Store with Jolla Account might break applications on your other devices, use it at your own risk!** Android support is not available from the Store, even if you can see Android apps listed (those will be removed eventually from store view)** This functionality means that image comes with only minimal set of pre-installed apps.
