Hi everyone, I am using a D6633 Dual sim Z3, I unlocked the bootloader today, and I flashed custom rom to see if it works, the rom works but it doesn't detect the sim cards, so I used xperia flash tool to go back to stock rom. It was working fine, but again I really wanted to try again to test if other Roms work on my device, so i used the "giefroot_v3" tool to root my device, and install the "lockdualrecovery" to get the recovery working on my phone, I boot in to recovery mode and I think I did a huge mistake, which is I didn't relized that the bootloader is locked when I went back to stock, I flashed the Roms and when it restart I CAN'T SEE ANYTHING!!!!!!

I CAN'T SEE SONY LOGO, I CAN'T SEE LED LIGHT FLASHING, NOT EVEN WHEN I PLUG THE CABLE IN :crying::crying::crying::crying:

Please help me ..................
