Does not boot into Recovery

  • check the installation guide [Installing LX in a Nutshell](Installing LX in a Nutshell)
    and try fastboot erase system + userdata

Bootloop / does not boot into Android

  • make sure you flashed the right ROM .zip for your device
  • make sure the ROM download is complete and the .zip is not corrupted
  • did you flash the kernel (boot.img) from the ROM? Other kernels are not supported.
  • did you really extract boot.img from the .zip you installed last, and flash it with fastboot?
    You cannot run a kernel from an older build. You must flash the kernel every time you flash a new ROM.

No Playstore

  • flash minimal version of from GApps here. Do NOT flash "Minimal X" GApps.

High battery drain

±10% drain per hour is usually caused by something keeping the CPU awake ("wakelock"). Usual suspects:

  • WiFi

    • Try Settings > Wifi > Advanced > Keep Wifi on during sleep : never
    • Some WiFi-routers are poorly optimized for mobile devices and send wake-up requests all the time, leading to high awake times and therefore high battery drain.

  • GPS
    Better do not turn off GPS manually; or reboot after turning off. It works better if GPS turns itself off when no app uses it.

  • Bluetooth Often changes. If you have a problem, the only 100% sure way is to reboot after using bluetooth.

  • Google Location Services
    Set Settings > Accounts/Google > Location settings : off and see if it solves the battery drain
    Change GPS/Wifi in Settings > Location access and see what happens

  • Bad apps
    If the built-in battery tool does not help you find it, try the BetterBatteryStats (BBS) app. The following two links can help you find the source of your battery problems:

    3G data often results in higher drain than 2G, but this is not as bad as wakelocks.

Running out of data / internal storage full

  • use Settings > Apps to move apps to the SD card
  • use the Link2sd app to move more files to SD
  • experiment with int2ext and related scripts here

Some games just display a blank screen

  • try adding this line to build.prop:

      ro.opengles.surface.rgb565=true

Headset does not work properly

  • test the headset with some other newer devices
    • if its working properly then this article will explain
      • solutions: get a OMTP CTIA converter cable or self rewiring on audio jack (exchange wire between mic and ground) or get a OMTP standard connector headset.
      • convert your CTIA standard headset to a normal earphone (no microphone function, so does the button) with only 1cm copper wire, tutorial: here.
    • if its still not working properly, your headset might be broken.

Boot Time is very long
