Your phone includes modified software can not be update HELLP !!

I cant repair my phone using Pc Companion or Sony Update Service !! :crying:
It says: Your phone includes modified software can not be update
Download your country firmware and flash with flashtool, then reconnect to update service. It will work then.

Then you can't update using SEUS or PC Companion.
Download the firmware you want from one of the threads and flash it using Flashtool.
Or go the adb route.

[Q] Sony Xperia S unrooting!!!! (back to stock ROM)

A couple of weeks ago I unlocked the bootloader of my Xperia S, rooted it and installed CM 10. Sins then a I have NO problems at all and i am enjoying the mod every day. But I was wondering, if I wish to get back to the stock ROM again (today the stock ROM is android ICS), how am i supposed to do that without worrying that I would brick my phone? :fingers-crossed:
Thanks in advance :angel:
Moved for better assistance, Thank you.
Relock your bootloader then fix your phone via Sony Update Service or PC Companion.
How can I relock my Bootloader? Can you give me a link?

thnx mate I really appreciate it:good:
(Don't worry I already clicked on the 'thanks' button )
Just flash your stock rom and re-root your phone, there is no way to brick your phone (there is just one way: unplug the cable while your are flashing a firmware )

Have you tried repairing your phone in PC vompanion?

pc companion cant repair it as it needs me to go to notification via phone which is impossible since it just bootloops from sony to xepria logo.

Getting your Phone back to a factory state DOES NOT require you to be rooted or have an unlocked bootloader, the thing that's lacking here is reading, and persistence. You need to figure out getting PC Companion, SEUS, or the Flashtool (Official and un-Official) to work, so as you know what to do, it's over to you to do it, and if it's not working then you're obviously doing something wrong.
i personally prefer flashtool. simple to use and doesnt require root or unlocked bootloader if you're flashing stock ftf.

Emma and Update services don't recognize my acro s!

Dears,
My Acro s with CM10 rom ( currently ) is not reconized by Emma or Update services!
I changed the rom and kernel but problem stays.
Unfortulatly i don't have back up of orginal software .
When I connect the deivce to Update services : Your device has a modified software
When I connect to Emma : the attached shotscreen appears
Any one had such problem?
Thanks
for update PCC and SUS your phone must be Locked Bootloader, for EMMA must be Unlocked Bootloader.

How are you connecting your phone? For Xperia S, to connect to EMMA your phone must be in fastboot or flash mode(can't remember which one). Have you tried connecting in these modes?
Edit:
That's an interesting picture.

Can't unlock boot loader or flash stock

Hi there,
Has anyone got a way out of this.....
I have a rooted C1905 that I have been playing around with. I want to try CM11 but boot loader unlock fails with a "FAILED (unknown status code)" report after I send my unlock code. I then thought I'd flash back to stock using S.U.S. but that fails too saying that I have a customized rom... which I don't!!! I seem to be stuck! is there anyway to force a stock flash?
Cheers
Have you checked if your bootloader can be unlocked? Go to the dialer, type *#*#7378423#*#* then go to Service info => Configuration. In rooting status, it should say "Bootloader unlock allowed: yes", otherwise it won't work. About your flashing problem, try connecting the phone directly in flash mode before opening SUS, by turning off your phone, holding Volume Down and plugging USB cable or by flashing a FTF file through Flash Tool...
It happened to me also ,check your IMEI CODE,you need to send first 14 digits of your IMEI,

Flashed an FTF of the latest but still can't unlock the bootloader. still get "unknown Error" and it wipes my apps.
Also can't use "repair my phone" on PCC as it says I have a Customised Rom, could this be due to me trying tools like flashgordon and debloat/deoxing flashing or routing? if so how can I get back to a stock state for a UK XM so I can start again?

Nope, but try this anyway.
1. Disconnect your phone and turn it off but keep the cable attached
2. Open PCC and go to Update
3. When it says no device found click the blue repair link
4. Choose Xperia M when asked to
5. Follow the instructions
I have a locked bootloader and modified ROM and it works flawlessly. Keep us updated

Hi there,
Thanks for the help, unfortunately it doesn't work! PCC recognises my phone ok so I carried on to the "repair my phone" tab.
and this is what I get after it's downloaded the firmware and tries to flash it...

Thanks for your help again.
