General Questions & Answers

​

Is the ROM suited for daily usage ? Google Apps compatible too ?

Yes completely. Nightlies and OpenGApps recommended.​

Can I flash CyanogenMod NIGHTLY and UNOFFICIAL without wipes ?

Yes you should be able to.​

Phone and telephony apps crash after updates ?

Due to the databases upgrades to support CM-13.0 -> CM-14.1 migrations,

the telephony databases may require to be deleted and rebuilt during the CM-14.1 bringup.

Backup your relevant phone data (SMS, Calls, ...), delete the following paths and reboot

/data/data/com.android.providers.telephony
/data/user_de/0/com.android.providers.telephony
/data/misc/profiles/cur/0/com.android.providers.telephony
/data/misc/profiles/ref/com.android.providers.telephony

Is the device encryption supported ?

State unknown. If you're coming from an older ROM

please read the details here : a07afb9660a86f702066003b8e81ab63789d1660​

When USB connected to a computer, I can't access the storage ?

The phone is in charge-only mode by default on Nougat,

due to a stronger security logic regarding unauthorised data access.

Swipe down the notifications and change the USB mode.​

I can't access the ROM's recovery with Volume-

You can either flash the boot.img from the newer Releases with "fastboot flash boot boot.img" or FlashTool,

or follow the instructions of the TWRP Recovery installation to update from TWRP.​

Against advices, I upgraded without GApps and now it crashes. Any way without factory reset ?

Yes there is, but nothing assures you'll manage to do it fully & preserve all your data...

Once booted, keep saying Ok to all "Unfortunately, ... has stopped",

pull-down the notifications panel, press the Settings icon,

go in Apps, menu, Show System, scroll to Setup Wizard (green Android logo),

Permissions, and activate Contacts + Telephone.

Later, some Play Store apps may need reinstalling.

If not ok, try this : CM Wiki

If still not, then I advise a clean factory-reset reinstallation...​

The AOSP Keyboard does not support swipe gestures ?

Unfortunately the sources for swipe gestures are not available

and Google still requires their prebuilt library to be there for AOSP Keyboard.

Download the following libjni_latinimegoogle.so API 23 from OpenGApps

and push it to /system/lib/libjni_latinimegoogle.so.​
