I not intend to add any mod or big change in original CM12.1 code, this ROM was build for the purpose of speed based on code optimization
It is based on latest source from CM12.1 with UBER patches, a Toolchain special build for Xperia Arc CPU and personalized device tree for better device optimization

Known Issues:
None

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

It is advisable to clean the data and start from scratch, it is not mandatory for those coming from CM12 Official but is advisable.
