[SOLVED] How can I flash the Official Xperia S 4.1.2 on Unlocked Bootloader - Sony Xperia S, Acro S, Ion

Current Phone Status:
Xperia S
Unlocked Bootloader
CWM
FXP CM10
I am very much keen to flash the Official upcoming 4.1.2 for Sony Xperia S devices.
But I'm really confused on how to get it done on my unlocked bootloader, once the new firmware is released.
Please take out time to give suggestions.
Appreciated.

Download ftf
Download and install Flashtool
Install drivers
Install JB ftf

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.

Going back to stock ROM

OK,
after having my Arc bricked and recovered, I had what I thought was a stock 4.0.A.2.368 ROM aboard, but when I connect to PC Companion it says that I have software that cannot be updated.
SEUS gets as far as connecting the phone in flash mode and then it says "checking connected phone" and then it hangs.
How can I get back to a stock ROM that will allow SEUS or PC Companion to do updates?
I am not interested in OTA updates.
I am passing the phone to someone who is not terribly technical and want for them to be able to do the updates via the PC at least.
Cheers,
A
Use the flashtool.

use the latest flashtool and latest stock ROM..!
latest flash tool here :- http://forum.xda-developers.com/showthread.php?t=1000012
Thanks guys,
but I thought that by using Flashtool to go back to a stock ROM, 4.0.2.A.0.386, that I'd be able to then use PCP or SEUS to go to the 4.0.2.A.0.42 ROM, but I could not.
SEUS just hangs and PCP says modified software that cannot be updated.
I have used Flashtool to go to the generic .42 ROM now, but what happens when the next official update comes out?
Thanks

lock your bootloader then update
Ah, OK, did not realise that the unlocked bootloader was the problem!
Thanks a million as they they say here!

Sorted! That worked, thanks to all!

[Q] ICS - How do I?

I have a Xperia Arc S
It currently has 0.62 firmware.
I have unlocked the bootloader (official sony way)
I have rooted (using XperiaArc.zip method)
I am currently downloding the ftf file for ICS.
Do I need a "kernel"?
How do I get ICS on it?
Will I still have root?
go to xperiablog dot net everything is there
ah well, flashtools not working for me
Edit a quick run of the drivers in flashtools and it was good to go!
read in the develepers thread, i am sure there is somewhere a howto. Step by step.

spam the menu button untill entered recovery.then wipe,then flash
nvr bothered bout baseband until yesterday,where i use flashtool to update the BB.
I have a arc S running on .42 rooted with locked bootloader. (I can unlock it but havent done so yet).
How can I install ICS from the released copy so far?
Or should I just wait for the release at my region?

6.1.A.2.55 Root & Flash Access

I have the LT26i boot loader unlocked Xperia S and it was updated to 6.1.A.2.55. Its still Android 4.0.4 and not much has changed. I am trying to root it and it get all the way to where I hit the restore button but then nothing happens. I figured I can flash it back to the 6.1.A.0.452 but I ran into a snag there too. The old ics driver is not working. I am running flash tool 0.9.10.1
Is there any work around for this? Your help is much appreciated
PS
I got the new update directly from Sony.

Hi it seems untilnow there is no option for root for 6.1.A.2.55, you have to go back to some other version .45 or .50 and root that one and flash a .55 sytem to get the latest updates.
The strange thing is, i did the same and i was getting still the notification to update to .55 and i uninstalled the update service aplication.
Good luck i hope this helps.
hey try this since your bootloader is unlocked,
1.flash advanced stock kernel or ka sspeed then boot.
2. after that reboot, then flash via fastboot kernel.sin from stock ftf of .55 firmware.
"fastboot flash boot kernel.sin" without the quote ,

The problem is I get a Driver error when I try to flash anything even though I installed the drivers so I am unable to flash anything in flash and fastboot mode so I cant go back.
Thanks for the help.. But the current version of flash tool cant seem to make changes it only recognize the device
download pda.net, this will install your driver.

I'm tired trying to root SONY XPERIA S with JB ROM .200. It's possible or not? HOW!!!

Well, if there is someone who rooted their SONY XPERIA S with JB ROM .200 please let me know, and how you did it, without downloading some heavy MB tools. Thanks. I have locked bootloader but it can be unlocked.
Try using DoomLord's script in Development Forum. I rooted my Xperia using that script and everything went fine.
I've tried, it says at some point that my phone is not supported, the model with ROM .200 only with .211

It might be a .200 bug. Why don't you try to upgrade to .211?? It may fix that problem...
In PC Companion is not yet . So any other way to do it, I Don't know.
Same problem
I have the same problem, I used to root using Bin4ry's method, but that no longer works, and I can't upgrade to .211 as it's not available in the UK.
This ROM .200 is full of bugs, but for me the most annoying is that the 2G is not working well when connecting to the internet.
I'm waiting for the official .211 if I cannot root it.

Hello ....
I had the same problem, mine was also *200 built Jelly Bean, I tried every exploit to root I could, spent all day messing with it, I did not succeed, I couldn't even get into fastboot or any method to enable me to flash this pre rooted ROM as it's zip format not ftf.
I eventually managed to soft brick my Xperia S, then I down graded to ICS, and rooted that very easy indeed, so I'm staying on ICS for the time being, didn't notice any vast improvements with Jelly Bean update anyway, and the phone works great now, I know with the version how to flash if I want too.
Hope this helps? .............................

I suggest you to first unlock your bootloader via the easy tool described at here http://forum.xda-developers.com/showthread.php?t=1560613
then flash the Doomkernel with the flashtool booting at fastboot mode. Before doing that never forget to install the necessary drivers.
The kernel is preloaded with custom recovery CWM and TWRP. While booting when you see doom logo pressing at 'vol +' you'll get CWM and pressing at camera button you'll get TWRP.
And flash the su and busybox package via recovery (CWM or TWRP)
for flashtool http://androxyde.github.io/
for kernel and su & busybox package: http://forum.xda-developers.com/showthread.php?t=2305591
& then enjoy Rooted jelly bean
ALL THE BEST !
I'll try. 'hope it works.
SONY XPERIA S
Nope. Not working. It's best to leave the phone as it is.
SONY XPERIA S
Well I managed to unlock my bootloader. Now i'm stuck on how to root it. any ideas?
First of all check your bootloader status.
*#*#7278423#*#* and then service info>configuration. If your bootloader is unlocked, it says 'bootloader unlocked = yes
And be sure that after installing the drivers you successfully connected the phone at fastboot mode. Long press volume + while connecting usb cable to PC. Flashing tool must detect your device.
After unlocking your bootloader rooting will never be problem.
And do it properly, this method definately works but you must be sure your bootloader is unlockable and unlocked also.

for the official update via pcc question it will inform you there is and update but you will not be able to install the official firmware through pcc even if UB and stock you can only update flashtool ftf file or with cwm flashable zip
yes you can relock your bootloader with flashtool to update the official way.
yes it will work especially if you are stuck in bootloop or brick as long as you can boot into flash or fastboot it
