[Q] Xperia Arc not booting after update OTA

I have brought xperia arc LT15i , two month ago.
i have unlocked the bootloader of LT15i.
Then update my Xperia arc LT15i from my cell OTA (OVER THE AIR ) only not from computer after that is not booting and it has been freeze or death.
I have shown my cell to service center also, and they also not finding any solution for that. and they r telling that your cell is not in warranty ok after unlocking the bootloder.
thy have also flash my cell then also cell is not booting up.
what is the solution..........
ok i understand that not in warranty BY UNLOCK THE BOOT-LOADER.
But Sony Ericsson people should provide me some solution for that.
IS IT POSSIBLE THAT MY CELL ROM MEMORY GOT CORRUPTED if ye the how to fix that thing or give me some alternative option.
plz plz plz any one can help me with my problem. will be very thankful.

[help] Xperia M can't install updates

Hey I'm new here so sorry if I explain it weirdly and I mistakenly posted this in a different section before
So my xperia M which is now unrooted can't install the 15.4.A.1.9 update it just downloads and reboots and goes to the boot up screen and loads for 2-3 seconds and blacks out and and restarts and it says couldn't install update. How can I fix this?

Try flashing a .ftf file via flashtool
Press thanks if I helped!

This might me the answer
Hey there!
I think i understood your problem and i have a question to ask you. is your bootloader locked or did u unlocked ur bootloader anytime and didnt lock it back.?
if your bootloader is unlocked , u wont be able to install updates from official Sony Update Center.
I dono if this is the exact reason y ur are unable to do but this happened with my phone too.
I use Sony Xperia M Dual C2004 and i wasnt able to install updates, then i noticed that my bootloader was unlocked then i used Flashtool to lock it back, then i was able to install the updates
Or if u want to install .FTF of your phone manually do it via Flashtool coz its safe
and if you want to get .FTF of your phone directly from Sony use PC Companion as Sony Update Service [SUS] is stopped
Hope it helps :angel::fingers-crossed::good:
