Once i tried to update my arc from GB to ICS 4.0.4 i had unlocked bootloader,so i had to lock the bootloader and then update via PC Compenion.Don't use those just use FlashTool for flashing FW and find 4.1.b.0.587 .tft file so you can flash it with FlahsTool.Try googleing for FlashTool for Xperia Arc and follow the tutorial,you'll get it.Good luck.Cheers

Thanks it worked, locked the bootloader and able to install the update

What if I root but did not unlock the bootloader?? Should I need to un-root my device first before update the system via PC Companion??!!

Bootloader has nothing to do with rooting, it will not affect it.
And you don't have to unroot.

How did you lock the bootloader ?
I have unlocked it for my "Sony Xperia U", but now I need to lock it again for updating.
Could you send a simple way for locking ?
Thanks.

If i am sure Xperia S and Xperia SL are the same devices, only difference is Cpu clock(S-1.5 Ghz SL-1.7 Ghz) So i think its the same relock way as with Xperia S.

I am pretty sure that the relocking ftf file over here works for S and SL - http://forum.xda-developers.com/showthread.php?t=1527159
Also, before you relock, just be sure to flash stock ics first with Flashtool and then flash the relocking ftf file.
Btw, you can still update to official JB with an unlocked bootloader. Once someone receives the update in his/her country, the ftf file will be made and released here for everyone. Also, Sony has their official Flashtool for unlocked bootloader devices.

Yes. You Can Flash Relock ftf. Both Are Same Device With Different Clock Speed.
It should not create any issue.
USING FLASHTOOL
First Flash The ICS (Exclude TA in Options)
Then, Flash The FTF Relock (Include TA in options)

I dont think the NEW JB would be available to download anytime soon.. So just wanted to Connect the Phone to PCC on my Xperia and Flash it.
Already Flashed ICS STOCK via FLASHTOOL on Phone but since its not MY COUNTRY specific
The build gives a few errors.
Just want it like the brand new as if its out of box with the New JB.
Please Reply.

You have three options -
1) Wait until someone releases the FTF file of stock JB and flash it with Flashtool
2) Relock your bootloader and try to do a software repair/update with Sony PC Companion/SUS.
3) Use Sony's official Flashtool for unlocked bootloader to restore your device to ICS/update it to official JB.
In my opinion, don't relock your bootloader but just wait until someone gets the update and makes the FTF file. Meanwhile, you can use Sony's official Flashtool and revert back to stock ics.

Which new JB? the ftf you download and flash is the same that you get from PCC or SUS, just using a different way.

[Q] Original Rom xperia arc s

I mount a prejudice currently cm10 (with unlocked bootloader), but I would like to go back to 4.0.4 Xperia, as when I bought .. I know that to do this I have to install the file. ftf from flashtool, I have to clear something to avoid having the FOTA brick unlocked bootloader? where can I find the original ftf file?

Flashtool don't need to relock bootloader. But if you want to relock bootloader, there are tutorials on this forum that show you how.
