SIM card not detected:
This often causes a bootloop
Cellular Modem bringup is now in HADK v1.1.1 section 13.3
Additional checks:
Replicate /dev/block structure from Android as closely as possible (for rild to be able to access the modem partition)
Run ls -lR /dev/block in CM
Run ls -lR /dev/block in Sailfish OS
diff the two outputs (this is WIP - android's toolbox ls might need more parameters to produce a comparable output)
If you see differences you need to add custom udev rules to create the correct /dev/block structure
For    devices with /dev/block/platform/msm_sdcc.1/by-name/ paths  (msm_sdcc.1   can be different) add to $ANDROID_ROOT/rpm/ these paths  and files with   contents, and it most probably will help (but still  paste your diff to   the IRC channel):
https://github.com/mer-hybris-kis3/droid-config-kis3/blob/master/sparse/lib/udev/platform-device
https://github.com/mer-hybris-kis3/droid-config-kis3/blob/master/sparse/lib/udev/rules.d/998-droid-system.rules
Some    devices have /dev/block/bootdevice/by-name/ as /dev/block structure  in   CM in which case you need to add the following line to the end of  the   998-droid-system.rules file in the last link:
ENV{ID_PART_ENTRY_SCHEME}=="gpt",    ENV{ID_PART_ENTRY_NAME}=="?*",  IMPORT{program}="/bin/sh    /lib/udev/platform-device $env{DEVPATH}",     SYMLINK+="block/bootdevice/by-name/$env{ID_PART_ENTRY_NAME}"
If    you have logcat and journal error messages suggesting that RIL/ofono    can't power the modem on and you have a qcom chipset, have a look in    your init.qcom.rc for lines that power it on when the boot animation    (bootanim) stops. If you have those, try this (paths may need    correcting): https://github.com/stephgosling/android_device_htc_m7-common/commit/9f4abdca65356090e6dd6f0356c5cf4a1870aa5f (note the typo there in the chown line!)
