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.

[Q] turn on unknown sources and debugging without switching on the phone

hi guys
i was trying to root my xperia arc by the given procedure in one of XDA threats. I unlock the bootloader and root it using a flashtool but when i tried to restart the phone again it stuck on SE logo screen. I tried everything and the worst part is when i try to flash it or even lock the bootloader again it says that debugging must be switched on. HOW DO I SUPPOSED TO TURN ON THE DEBUGGING WITHOUT SWITCHING ON THE PHONE?
please help me on this, thanks alot

You were supposed to turn it on before rooting. Now all you can do is reflash, turn the phone on, turn debugging on and allow non-market sources then root. Try wiping all data while flashing and see if it works.

I forgot to turn it on and i cant turn on debugging cos my phone doesn't start.It stuck on SE logo screen.Hurry guys help me.
BTW i contacted the Sony Ericsson and they said send them the phone and they will have a look. What you guys say about that, should i send it or not?

[Q] Xperia Play R800i is not sim card signal

hi, i have a xperia play and i actualized.. but now, dont have simcard signal.. anyone can help me?

It heard like you had crash your baseband.
If you have an unlocked bootloader flash your system again.
If you doesent unlocked it try to Update your Sytem via SEUS or PC Companion.

Try to use this its for unlocked bootloaders http://developer.sonymobile.com/services/flash-tool/how-to-download-and-install-the-flash-tool/ works on arc
As tangosierra_ said do not accept over the air updates if your bootloader is unlocked if the above not work contact here http://forum.xda-developers.com/showthread.php?t=1252038 :good:

thanks for answers, managed this on my own, i used a ftf file that relocked the bootloader so i could fix it through sony pc companion

[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:
