you can flash 2.3.4 firmwares {ftf} again via flashtool to downgrade..!!
Sorry for the noob question but can i use flashtool to downgrade back to GB even if my bootloader is lock?
Yes, but you can downgrade to 2.3.4 only. You will risk damaging the fuel gauge(0% battery problem) if you downgrade to an earlier version.
Yes, using flashtool flashes the stock kernel/firmware. If your bootloader's unlocked you could use pc companion to repair the phone if the official ICS isn't available in your area yet.

Where can i get 2.3.4 generic for all regions?
Actually since you upgraded to ICS doing the repair via PC Companion will detect that you have the ICS version on your smartphone and will download, wipe and install the ICS even it if the ICS update is not available in your area.
I know because I did a repair job because I want to wipe it clean with a fresh install of the ICS and I am happy with it. So it will not repair and install GB 2.3.4.
As commented flashtool and download the GB 2.3.4 on here to downgrade.
where can i download generic ics ftf file?
i search over and over and i check the site daily to find any way too root officially global world.431 without re flash (ready to root firmware)
i need root to slove small internal memory problem
any way id like to ask what is the disadvantages of flashing (ready to root firmware)?
and if i flash (ready to root firmware), can i update my mobile normally via witless?
there are no disadvantages, it's just the normal 4.0.4 FTF with the 4.0.3 kernel.
just don't flash the FR because tether doesn't work from some reason.
and for sure there is no differnt with 4.04 kernel and 4.03 kernel?
and if u have the rom, how is the battery with you?

read the tutorial carefully, after you done rooting you need to flash the 4.0.4 kernel
the battery is almost the same as GB for me.
rite, i didnt notice that
thanks alot
Pardon my lack of knowledge in rooting and stuff. This is my first android phone Lt15i. I read many tutorials regarding rooting but all I got an idea was that rooting can be done when the Android version is 4.0.3.
I recently updated the phone to 4.0.4 Fw 4.1.B.0.431 via PC Companion. Now I don't understand how can I root my device and I need an app badly which only works with a rooted device. A nice simple step wise method would be appreciated.
thanks in advance
Also the bootloader is locked
Like you mentioned, there are already threads which tell you how to root your phone.
Go read OverLo4d's thread in the General section. The steps are clearly given there.
But in short, what you need is the 4.0.3 kernel. Flash it with Flashtool. Root your phone with DooMLorD's rooting toolkit and then flash the 4.0.4 kernel back.

hey everyone,
I updated my Xperia Arc to ICS via the sony pc companion update. But how do I root this version? Should I go back to gingerbread and root it or is there a way to root it directly, without going back?
Thanks.
If you have firmware 4.1.b.0.431 for ICS 4.0.4 then https://www.google.com.au/#hl=en&sc...=667&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&cad=b or just search what ever firmware you have on google or xda
if you have ics 4.0.3 then u can root it using doomlords oneclick root method. if it is 4.0.4 then u need to flash kernel of 4.0.3 and then root and then u can come back to kernel of 4.0.4 by flashing just the orignal kernel again. or you can download a ready to root 4.o.4 ftf and then flash it on your phone using flashtool.
for 4.0.3 http://forum.xda-developers.com/showthread.php?t=1601038
for 4.0.4(ready to root) http://forum.xda-developers.com/showthread.php?t=1683957
you can root your phone using these simple 3 methods in Here.
Does it void our warranty ?
Sent from my LT15i using xda premium
well i am not 100% sure but i think that rooting wont void your warranty. unlocking bootloader voids your warranty because, root does not remain if you flash another firmware however, an unlocked bootloader is permanaent irrespective of what ever you install on it.
this was my logic however, remember dev's have shown how a bootloader can be relocked. get more info from here http://unlockbootloader.sonymobile.com/
I'd just like to say hi to everyone, my name is Mick.
I have an Arc S, originally running GB, but currently running ICS, build 4.1.A.0.562 which I updated to via SEUS a while ago.
I've used DoomLord's one click method to root the phone, have CWM installed, and I've been happy with it since, but I've now decided to see about installing a custom rom.
I've done a lot of reading on here about locked and unlocked boot loaders, and mine's locked so a bit restrictive in what I can do I gather.
What I'd like to know is, a lot of the roms for locked bl's, say based on, or must have, the .587 build, but mine is the earlier .562.
What is the best way to proceed?
Can I flash the .587 kernel with flashtool as I've read that the stock, signed kernels can be flashed on locked bls. Is this right, and does flashing a stock .587 kernel affect rooting?
Any help, or links to whatever I haven't found yet, would be much appreciated.
Cheers,
Mick.

First, .562 update is crap. Sony released a crappy 4.0.3 update, better update if you can.
Then installing stock firmware before installing a custom ROM is not necessary.
Yes, there is difference in .562 and .587 kernels. Apparently, .562 kernels have a security hole in it, which can be used for rooting, however .587 kernels don't have it anymore and you will have to install older kernel to root and then install newer kernel back.
Yes u can flash .587 kernel using flashtool & this will not effect on root... But I will suggest u to update ur phones firmware to .587 (.562 is full of bugs), root it & install cwm then flash stock based custom roms which supports locked bootloader..

It does. 4.1.A.0.562 kernel has a security hole in it, which is used to root via DooMLoRD's method. .587 kernel has that hole patched and that root method does not work.
Thanks for the replies.
Ok, so this means that I can use flashtool to flash the .587 kernel, and then whichever rom afterwards.
I have tried flashing roms with the .562 kernel, and they do work, but I get odd glitches.
The Walkman app in Zelly Cream 2.0 for instance says it has unexpectedly stopped whenever I click on My Music, and the Ultimte HD rom is really good, but the native Movie player won't work and does the same whenever I click on a video.
Each app works ok on one rom, but not on the other.
At the moment I've got the Zelly Cream rom installed and just disabled the Walkman, so had to download another player.
So far I've not had any issues with boot loops or anything, but I have been wiping properly before installing.
I have got a stock .587 kernel I found on here, so I'll try flashing that and see if it's any better.
It's a shame the boot loader is locked, but I've also read that removing the sim lock can fix this.
Thanks again for the info. :good:
587 kernel
Sorry, has anyone got a link for a generic .587 kernel as when I search, the ones that come up have been modified in some way, and my boot loader is locked.
Thanks.
Got it
Ah, it's ok, I think I've found it.
The first one I downloaded was reproting LT15 in Flashtool, so after a bit more searching found it here
http://forum.xda-developers.com/showthread.php?t=1838830
Should be ok.
Just download the whole ROM, but choose only kernel to install.
Sent from LT18i with custom firmware by myself.
Your phone's not covered under warranty anymore, so why don't you try unlocking the bootloader? Would barely take a few minutes.
Hi, Flash new .587 firmwar..... flash .562 kernel only.....root phone.....flash original .587 kernel only.....this video helped me a lot.
