Not developed actively anymore. You can update to cm-13.0.

This is an unofficial build of CM12.1.

This is an attempt to stay close to official cm12.1 and not make crazy hacks to make things working.

This is a pure CM build, only contains official CM features. I will not add any other external feature/app/etc.

WARNING: This ROM uses a modified internal memory layout.

Our /system partition is originally 400MB but this space is not enough for a fluid experience and a full installation with proper google apps.

The internal storage has been repartitioned to give the whole space to /system & /cache. You will need a secondary partition on your SD card to be used as the /data partition.

If you want to use this ROM you will always have to use the included kernel or use a kernel that includes the layour changes. Bug reports with non-standard kernels will be ignored.

You will have to wipe the device and make a clean install.

You cannot restore nandroid backups from previous android versions or restore backups from this ROM to other ROMs that don't use the new partition layout since you risk corrupting the data.

I suggest to use Titanium Backup, Helium or any other similar app to backup your data if you really need to.

Requirements:

* Have the stock ICS 4.1.B.0.587 full ftf flashed (doesn't matter if you have flashed it in the past or if you flash it before installing cm12.1, it will work both ways)

* LT15i (Arc) users need to flash LT18i (Arc S) ftf

* MT15i (Neo) users need to flash MT11i (Neo V) ftf

* Minimum 2GB secondary ext4 partition for /data on class 10 SD card.

Steps required for correct installation (order is important):

1: Flash boot.img in fastboot & reboot into recovery

2 (optional): If the device is not booting, reboot to bootloader again and run:

fastboot erase system

3: Enter recovery

4: Format /system using System-Formating-Tool_signed.zip (can be found here) , then /data and then /cache (Important step!)

5: Flash update zip

6: Flash gapps

Steps 2, 4, 6 are not needed when you install new LX build on top of an older one in the future

If you want to return to a ROM that doesn't use the new partition layout, you need to follow the above steps again (only replace boot.img & update zip with the ones you want to use).
