i tried to update my xperia Z to 4.2.2 , in the beginning it worked but the system got unstable and started crashing , loosing signal or just turning off and not going back on until connected to the charger , so i flashed another stock rom and then it wont boot the system it would pass the sony logo and the xperia logo but reboots when the color strings start going across the screen so i tried these ways :
relocked the boot loader and uses sus and pc companion to reflash ( caused the phone to restart as soon as it turned on at the sony logo )
i tried unlocking the boot loader and flash another stock rom ( it flash but same problem )
i tried to flash boot.img from the rooting kit using fast boot and the same problem continues
now the phone turns on but it restarts at the sony logo so i guess the boot files are corrupted is there away to solve it ?
i have tried different Stock Roms to flash but nothing is working. need help

Hi there,
My issue with my phone is as follow:
1- I was having a phone call @ below 16% battery charge (cheap Chinese battery replacement) and the phone died and so far it 's OK until I tried turning it ON and got stuck on SONY boot logo, charged it , retried with no good same SONY logo with no move, it charges up to 100% but won't boot up
2- then I tried laptop connection yet not identified not by the computer nor by the Sony PC Companion or the Xperia Companion, and even if I haven't tried rooting it before or something but stupidly I tried flashing it 's stock tft file and things got worse , so after the phone was stuck on the SONY boot screen it changed to give me the famous update error "The software update failed make sure that your phone is connected to the computer and try again" and to be honest SONY 's Companions used to be -for me- one of the best and the most powerful yet it didn't help.
3- The phone is still identified as C6903 on the flash tool and detected in the flash and fast flash mode yet I can't do anything apart from that.
4- I tried the unlock boot loader code to unlock boot loader and re-flash the stock ROM but I couldn't may I don't know how to do it right I'm not sure
And I'm sorry for the long essay but I'm really freaked out
So can anybody help?
Thanks in advance for your responses
