Use flashtool and flash .42 firmware, use that method or doomlords zergrush, and upgrade through your phone(not pc)

Xperia arc S update problem

I have Xperia arc S with android 4.0.4 (build 4.1.B.0.431), i want to install latest update (4.1.B.0.587) via sony pc companion. Every time i try to install, pc companion popping up window with this message: http://postimage.org/image/n79vyhstx/
Does enyone have idea what causing this problem
Thanks in advance

If you have unlocked your bootloader, re-lock it
take the SIM card out of your phone and reboot phone

My bootloader is unlocked, but won't let me install update. How do I re-lock bootloader??

Download Link
Flash this ftf file via flashtool from the download line --> www(dot)mediafire.com/?g1b5j712ajx4yjd (not allow to post outside links, sorry!)
And your bootloader is locked again!

No need to relock bootloader to get the update. Download complete update 4.1.B.0.587 from here, put it in "C:\Flashtool\firmwares" (if Flashtool is installed in "C:\Flashtool") and flash it using Flashtool. I did it without problems. Use the "flashmode" in Flashtool, I selected "Exclude FOTA" option, so only baseband, system and kernel were flashed..

Help?
i relocked my bootloader to update to 4.0.3(latest). But now i want to unlock it again to flash a custom kernel and rom. is it possible?

[Q] Bootloop on LT15i

My LT15i got upgraded to .62 version via OTA and I wanted to downgrade it to .42 to root it safely and easily. Something didn't work out and after flashing the downgrade my phone got bootlooped. I downloaded different official ROMs to go back to, but I can't flash them

Any ideas what can I do? I didn't use fastboot since I'm not sure what should I do with it, just flashtool.

Just keep flashing it or use Update Service to repair it.
There are dozens of generic ROMs.
e.g. http://forum.xda-developers.com/showthread.php?t=1491066

Use Flashtool repeatedly.. doesn't always work the first time around..
Does the LED indicator change after a while of being plugged in in flash mode? Check this, as I kept having the same issue. I just kept yanking the cable out and plugging it back in and repeating the procedure over and over until it fianlly flashed the kernel for me.
Was using arcknight kernel when i got stuck in bootloop, flashed to stock kernel and repaired over SEUS before unlocking BL and rooting once again using zergrush

Follow these steps.
pre requisites - Rooted/Bootloader unlocked.
1. Download the Flash tool.
2. Download the generic global rom - LT15i 4.0.2.A.0.42 (.ftf) [Search in the forum]
3. Flash the ftf using flash tool. (google how to flash using flash tool. There are numerous threads)
4. Once you successfully installed .42 firmware. [Using flashtool root the mobile using zergrush method. if u want]
5. Install busybox using flash tool.
6. Install x-parts from play store to install the CWM.
That's it.
Let me know if u have any problems.

The problem is, I used to have root and CWM installed, but now I can't enter it, because when I flash the ROM, it gets stuck in certain moment. I'm stuck somewhere between 3 and 4 point, where my flashtool doesn't correctly flash the ROM onto my Lt15i. From this bootloop I can't reach CWM or normal system to enter the google play or something.
I'll keep on trying flashing it, I'll also try to flash it from another computer
Is it possible that flashtool is being blocked by certain application like, I don't know, PC companion?
Additionally, I can't go back to the stock ROM via PC companion or SEUS, because when I'm in flashmode and phone is ready to flash, the PC companion says that my phone is already upgraded and there are no new updates to it, so it can't be upgraded, even tho there is some old flashed ROM inside ( I think PC companion reads the old ROM, that I used to have before bootloop, I believe it was the 4.0~~~~.62 version)

Disable antivirus and run the flash tool with adminstrator. Try to refalsh the .42 firmware.
Try to flash the .42 ftf with old version of flash tool. I saw some cases where with new flash tool, .42 is not flashed successfully.

[Q] arc updates

hI,
i m using xperia arc , 4.0.4 build number 4.1.b.0.431 rooted. when i try to update to version 4.1.b.0.587 through OTA, i m getting the error "could not install"
so please guide me to get updated to that.
thanks in advance.

Have you installed any mods, or CWM?
That might prevent you from updating OTA. You can root 587 directly though by doing the sane process as 431.
Sent from my LT15a using xda-developers app

Prerequisites:
- Instert .587 fw in Flashtool/firmwares
- Insert .431 and .587 kernel in Flashtool/firmwares
1. Open flashtool. Press the thunderbolt / scar or whatever it is. Select firmware .587.
2. When it is prepared, power off ur phone. Press back key and connect it. Flash it.
3. When the device has rebooted, do the same but flashing the 431 kernel
4. Root the phone with DoomLord toolkit
5. Flash the .587 kernel by the same method
U will have rooted 587
I don't know if there is any newer method, since I have ul bootloader and I root by flashing kernels
Hope it is useful for u

If your BL is unlocked
you must lock it again.:fingers-crossed:
