Instructions

• 1. If your device has ICS, bootloader unlocked, rooted and custom kernel capable of running init.d/recovery then skip to 5

• 3. Unlock your bootloader from http://unlockbootloader.sonymobile.com/instructions
• 4. Flash Xperia P’s Kernel with autoroot/init.d/recovery support from http://forum.xda-developers.com/show….php?t=1841613
• 5. Flash Xperia P: Fidelity GX in recovery
