[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

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] update to ICS stock

hi. I bought ARC S LT18i from hong kong . it is using android 2.3.4 build number 4.0.2.A.0.62. I want to update to ICS .
(it is unlock without carier)
as I see on www.sonymobile.com
Latest available software: 4.1.B.0.587
Release date: 2012-08-16
but PC companion and update service says that I have lastest software.
when I try to software repair with PC companion. it says that doesnt have software for my phone
I want to update without flashtools using only sony's soft.
can someone help?

If the PC Companion says that you have the latest update then you have no other way to use Flashtools and flash an ICS ftf to update the Phone.
And there's nothing wrong to update the phone using flashtools.

You can use SEUS to update although it would wipe your data.

[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:

Once rooted even if you unroot before installing updates it won't work system has been modified re-flash ftf via flashtool or try software repair via Sony pcc

so you unrooted and flash with flashtool,and the effect is not booting up?Is there any LED light when you try to turn the phone up???The problem flashing with Xperia Companion or PC Companion is that the phone has to be booted up.
EDIT:I saw somewhere here on xda forum that xperia companion might work if your bootloader is still locked.
