view story

http://forum.xda-developers.com – I am using NEO V, and using Jelly Sandwich before, and backup already before install another ROM (LOCKED BOOTLOADER) This one: http://forum.xda-developers.com/show....php?t=2023472 after I complete part I, I can't reboot into recovery. Then I tried Recovery X, but after that, when I start my phone, it stops at the "SONY" LOGO.. I am very worried now, is that bricked already? Even if I use Flashtool , I can't connect it in fastboot mode. If not, what should I do? (HowTos)
