WIKI FOR UNOFFICIAL Lollipop 5.0.2 CyanogenMod 12.0 for S4 Mini 3G & LTE by F4k

​

I'm not the developer for these ROM, nor do I work for Cyanogenmod, I just maintain this thread as a hobby. Please don't PM or spam me to answer your questions. This thread is ONLY for the CM12 UNOFFICIAL discussion, there are other threads in the general and Q/A forums to answer questions about everything else than CM12 roms.

Arco68 is the maintainer/developer in charge of maintaining/developing CM for our phones. He isn't in charge of developing everything on CM, for example trebuchet or other feature development. F4k is the most active mod-developer for our phones, but he doesn't work for Cyanogenmod either.

1st rule of flashing custom roms etc.: No wipe - No whine.

2nd rule of flashing custom roms etc.: Always backup before flashing/updating.

3rd rule of flashing custom roms etc.: Google search and xda search are your friends when encountering problems.

In this thread I will try to regroup the solutions found to some problems that users encountered with this ROM. If you have been confronted with problems on this ROM and you have found a workable solution, thank you for posting it on this topic in order to share it with everyone so I can update this topic !

Lost password/connection WiFi

-​

Go to the Settings menu then to WiFi.

Press the menu button then to Advanced Options.

Disable

the option Scanning always available.

One option you might not need is Scanning always available. This allows apps to scan for networks even if Wi-Fi is turned off. Always scanning can affect battery life, and most likely, you won't need this option enabled.

Another option is Wi-Fi frequency band. Depending on what type of router you have, it will support only 2.4 GHz, only 5 GHz, or both. If your router is old, it probably doesn't support 5 GHz.
