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?

You'll need to flash an ICS kernel e.g DoomLords Advanced Stock

[Q] Downgrade from ICS

I have a nandroid backup of the .42 gb rom and im currently on stock ICS.
When i restore the .42 rom i cant start my wifi, as the kernal remains of ICS.
I have a locked bootloader, Arc S.
Can I just flash the kernal after restoring .42?
And can someone plz explain how i do this?
And if i need just a kernal file can someone plz gimme the link for it?
Thanx...

Use "repair phone" in PC Companion, it'll remove everything and flash rom, correct kernel etc.

Pc companion is not detecting my phone when i restore .42

Can u provide me with a .42 ftf ? Im sorry, cant seem to find one. Dont want to use wontan. Im stuck on ICS. Any help would be nice plz.

Most stock roms are here
Usually the resources for ARC/ARC S are in the "Xperia Arc General" Section

And from unlocked bootloader? Can do directly with FlashTool or first I have to flash the Stock Kernel?

Downgrade from nandroid
Hi,
I have a xperia neo....with rooted stock firmware .62 and unlocked bootloader (testpoint method)...I have taken a nandroid backup of it
I just wanted to try out ics...so planning to update using PCcompanion
Before updating...i just want to know
1. whether it's possible to downgrade to gb through cwm nandroid restore? Do I need to flash the kernel for .62 after the nandroid restore ?
2. will root access be restored after the downgrade? Since .62 is cannot be rooted, I'll have to flash .42 to get root access
I don't want to start restoring all the installed apps...hence thinking of using nandroid backup against flashtool

[Q] how to root xperia arc with stock ICS

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/

Is it possible to upgrade to Kitkat with a locked bootloader?

I have an Arc Lt15a with a bootloader that can't be unlocked. Am I stuck with Ginger bread or can I update to Kitkat? Some apps I want need Kitkat. Thanks in advance.

You're stuck with GB or ICS.

As popthosegaskets said, you won't be able to. KitKat requires own kernel with proper ramdisk, which can only be flashed by having unlocked bootloader.
