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).

Guys, please read new instructions... There is no need to use int2ext or link2sd, while 2nd partition is automatically mounted as /data and any app you install and all their files, go directly to SD ;)

To use root you have to enable Developer options and set root access for "apps and ADB"

Can anyone here perhaps help me with installing the usb drivers for my Xperia Arc please?.. The flashtool drivers aren't installing right, they keep giving back failed responses!.. Plus, I don't wanna go through that signature malarky crap!.. Is there any other way I can get the drivers installed on Windows 8.1 so that I can flash this ROM, PLEASE!!!

Thanks...

To set a real dev discussion:

I was supposed to so something else, so I started reading through my kmsg.log and of course I found "ti_st_open: st_register failed -22" which is followed by 2 min of suspend (being stuck at boot logo). I googled it and found out it is related to bluetooth driver. Those codes from our kernel sends that error:

https://github.com/LegacyXperia/and...c2dac8e3446a7695/drivers/misc/ti-st/tty_hci.c
https://github.com/LegacyXperia/and...c2dac8e3446a7695/drivers/bluetooth/btwilink.c

But why I'm mentioning it after all. After some research, I have found on TI Support page some thread related to wl1271 with the same issue in log:

http://e2e.ti.com/support/wireless_connectivity/f/307/t/237355

According to it, problem is related to GPIO BT_EN suspend/power down sequence, which have bad effect on next power up.

GPIO is handled by:
https://github.com/LegacyXperia/and...2c2dac8e3446a7695/drivers/misc/ti-st/st_kim.c

@mikeioannina is it helpful?

Hi,

how does the partiontable of the sd card need to look?

I mean is it enough if there's any ext4 partition or can the whole card be formatted as ext4?
Which filesystem should the default? part be?

Hi,

The install script will mount your second partition as ext4, my suggestion:
  1. first partition fat/fat32 for "external SD" in the ROM
  2. second partition ext4 for the /data partition
Both partitions should be primary partitions

    We are very close to release, just need to figure out some bugs and write proper instructions for new unified partition layout.
    There is no point of unofficial releases on xda, since I am sure many people will flash it and then complain it's broken.

    You are free to build from the sources yourselves but releasing unfinished stuff on xda can lead to noob soft-bricking their devices or 'help plzzzzzzzzzzzz!!!!!!!111!' messages

    cm-12.1 support will stop after the next release, so we can concentrate on cm-13.0.

    New builds

    Hi guys, after long time some new builds are coming.
    I have included some improvements for LPA, you should be able to use it now to get rid of music stuttering.
    You can test it by adding lpa.decode=true in build.prop. It is known that LPA breaks a2dp streaming, we are trying to fix it.
    You might also notice that the headset volume is louder than usual and audio effects might distort the sound.

    ## Nightly build 20150723 - cm-12.1
    * Latest cm12.1 changes
    * Use upstream gp2a proximity sensor kernel driver (zeus)
    * Fixed CVE-2015-5366
    * Decreased zRAM size to 128MB
    * Added support for DM9601 based USB ethernet
    * Fixed mounting of non-FAT formatted SD cards
    * Set FIOPS as default IO scheduler instead of ROW
    * Updates & fixes for LPA
    * Testing lowmemorykiller changes to improve zRAM OOM issues

    Builds will roll for all devices tomorrow, after the cm-11.0 builds are up.
