[Q]

so i have rooted xperia arc. noticed that there were new update (4.0.2.A.0.42). so i resetted to default settings cause otherwise it wouldnt let me install that update, then after about 5 mins of updating arc shutdown and now it wont turn on.. so i ask what should i do?

was your arc bootloader unlocked when you did this?

When your BL is locked, just flash it via SEUS.

yes, bootloader was unlocked.
thank you for quick replys

There is a fix in the sticky's
For future only people who unlocked with setool can update via FOTA, SEUS and PC Companion.
Unless you relock your bootloader

that was usefull! thanks, only problem now is that it wont connect to pc cause pc cant install "s1boot download".

You follow the link in the tutorial closely? Needed drivers are in the flashtool directory

found them but dont really know which one i need or where to put..
edit: now that flash started but it tells me to turn debugging and uknown sources on... but how cause i cant turn that even on
edit2: after reading almost full sticky thread tried that xperia play firmware which someone said it worked, now when i try to turn it on green led blinks.. is my phone piece of junk now?

so anyone know what should i do? it wont turn on, green led blinks when i press power button, phone vibrates when i press menu button (to start fastboot).

In Android Developement of Arc is a sticky with a fix for FOTA bricked phones, just do that

i cant seem to fix it through sony pc companion either, is this due to i got an unlocked bootloader?

is your bootloader unlocked? NEVER accept any OTA updates with an unlocked bootloader, use flashtool!

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

[Q] Bootloader Update

Hi guys!
I have a Xperia ZQ (Brazilian version of ZL).
I got a Second hand device and i flash it many times, all i get is flashing red lights or vibrate once and wont boot. (depends on the firmware)
I cant get it working but i do have flash mode and fastboot mode.
IMO my bootloader is dead (if it is even possible). can you guys help me update it?
Or maybe give me some new ideas for fixing it? :fingers-crossed: :crying:
I've tried SEUS, PC companion (repair my phone), Flashtools unofficial and SeTools (box)

You can relock the bootloader with flashtool, check out my guide. But why would you want to do that

Hi Friends,
I'm trying to unloack my Z1C using the latest verson of flashtool and after connecting it in flashmode it will not display the window showing model numbers and display a window asking to switch off and connect again in flashmode.
I've tried it on 3 PC's, still not unlocked the Bootloader. What is the difference between unlocking bootloader from Sony official method and Flashtool method. Please guide me.
Regards
Shashi

Iirc the first unlock has to be done the official way, then you can (re)lock using flashtool. And the correct drivers have to be installed of course.

Dead Xperia T3

Hi, my Xperia T3 randomly turned off. Now it doesn't turn on, red and green LED blink. It didn't had unlocked bootloader and it wasn't rooted, USB debugging was not on. How to flash firmware without flashtool without unlocked bootloader? Please help, thanks on advance.

You can use the Xperia companion software to try and restore the firmware. Keep in mind you'll loose your data though.
