If i flash a ROM on z5 premium i lose my drm keys?
depends on what are you flashing and which mode?
flashmode = is to flash original sony stockrom and/or its sections (original kernal.sin, system.sin etc)
you will not loose any DRM KEYS
FASTBOOTmode = you can flash boot.img files (modified kernal, roms, 3rd party stock roms like cynogenmod, Miui etc)
you will have to UNLOCK your bootloader in order to flash via fastboot mode and YES YOU WILL LOSE YOUR DRM/FIDO KEYS since TA partitions will be WIPED once your provide unlock key to your device.
There is a way to backup the drm keys?

over the internet you will find many forums locations having .ftf file of original stockroms. even on xda many users have uploaded version of original stockroms. its usually above 2.4GB (.253)
however i have my confidence on xperifirm.
on flashtool, click the XP button (the last button at the right) it will launch Xperifirm. Find you device and select latest version and download. once downloaded the flashtool with prepare ftf file for u to flash ( with so many options for you to flash or not to flash (exclude / include, wipe/keep userdata and apps data ETC)
plz check fotos

STEPS TO UNLOCK BOOTLOADER
1) Get the IMEI code for ur device: type *#06# in phone dialer to find it out, note only the digits (no dashes)
2) download the fastboot package with usb drivers(GOOGLE IT)
3) Now Get the UNLOCK KEY FROM SONY from HERE
4 ) After u have verified that u can unlock bootloader, scroll to the bottom of the page and click "Continue"
you will get numerous prompts, read all info and if u agree click on "Accept"/"OK"/"Proceed"
finally u will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address
5) Extract fastboot_with_Android_USB_file.rar and open fastboot folder
6) Hold SHIFT and right click on the background of the folder Select 'Open command window here'
7) Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
8) In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the phone is correctly connected
9) Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which u received earlier.

good job bro!
I just wanted to ask if we could unock the bootloader using flashtool so there's no chance of voiding warranty. As backing up TA would save DRM keys.
Yes u can unlock it using flashtool. I am windows 8 so i find unlocking with fastboot is easier and it just just cause 6 mb of data.

You need to restore the stock boot partition because restoring TA partition will relock the device or else you will soft-brick it. If you have a dump of it you can restore it before restoring TA partition, otherwise you need to reflash with flashtool or SUS.
This is what I learnt from other Xperia devices in general.

Can you still use SEUS when you have unlocked the bootloader to restore the original firmware prior to re-locking bootloader?
I thought it would be via flashtool only, because as soon as you unlock the bootloader you lose access to PC companion and SEUS.
The reason I ask is I have an XPERIA X10i and you can use anything at any time and it doesn't care.(brilliant olde device)
With my XPERIA S, I only have flashtool, as SEUS and PC Companion (and Sony OTA upgrade) are 'lost' after the bootloader is unlocked.

Really? PC Companion can recognize my Xperia M. Haven't tried SUS restore but it should work, shouldn't it? FOTA updates are known to brick unlocked Xperia devices so I strongly advice you not to try it.
But anyway if you've already restored the TA partition you already have a locked bootloader

PC companion still can recognize your phone even you've unlocked your bootloader, but updating your phone with SUS / PCC will surely brick your phone.
The only way to restore to the original firmware is using Flashtool or EMMA :fingers-crossed:

I dont think Pc companion will brick your phone! I never heard of this things and yes updating through FOTA can definitely brick your phone. Although i recommend not to unlock bootloader unless you are an advance user or a developer.
Sony xperia M gives very good performance over stock so noo need of scripts and other stuff, and i hope someone will develop CWM for locked bootloader too.

I have NOT backed up my DRM keys.. and I have an unlocked bootloader...
I connected my XM SS to Sony PCC..
It did recognize my phone.. However it did not update it stating that I am using a modified software..
Flashtool (EMMA) also recognized my phone.. but dint allow me to update my phone..
And my phone is not BRICKED..
Can you be more descriptive on the exact instructions on how you can relock XM whose DRM keys are not backed up?
Has anyone tried this?
Please quote and reply and share the method if you have tried this on a C1904 XM SS and if it is working !!!!
Thanks

Hi,
I'm new and quite a newbie with android so, please bare with me
I will try to write a comprehensive guide on this during the process.
My device is XperiaSL LT26ii / Android 4.1.2 / Kernel 6.2.B.1.96 (stock, or default kernel) Rooted with bootloader locked. Busybox installed.
So the only thing I'v done after buying is rooting it.
- How to fully-backup / recovery if anything goes wrong
Before doing any operation with it I wanted to backup everything (applications, ROM, System, documents) , and I hear that there is CWM or Xrecovery for that (mentioned in some guides), nandroid, but I found different applications on Playstore and don't know which one is the right one for my device.
I understand that backing up and restoring each of these system parts requries order and probably different applications,
Can we specify here which app should I use and how it's done?
- ROM and Kernel without unlocking possibly
http://forum.xda-developers.com/showthread.php?t=2593806 it looks like possible but considering that now there is cm-11 out and not yet for "nozomi" http://download.cyanogenmod.org/?device=nozomi , I would like to try any stable, fast , light ROM out there which works for my device. Preferibly with possibility to remove any google app .
If not, how can I unlock the bootloader and do the rest?
I saw also http://forum.xda-developers.com/showthread.php?t=1617219 which looks a nice kernel.
So , what's the most adaptive ROM / kernel for my phone and how to install / flash them?
- Getting back the applications
Once it's done, how to restore back applications and data? / with what tool, without loosing anything.
Download flashtool (xda fileserver)
You can use that to unlock your bootloader
Also backbuton = volume up = BOOTLOADET MODE
Menu button = volume down =flashmode
May come in useful for unlocking your Bootloader
Also emma flashtool isnt the same as this flashtool
Also google if your not sure
If you want to know anything else then ask
Sony Xperia S was my first android
Had a nokia brick before (3310)/N95)

Before unlocking the bootloader , I'd like to backup everything with CWM or Xrecovery or nandroid ,
I tried installing CWM but it said my phone was not supported, so I gues I'm on the wrong place, so could you point to the right CWM?
Also, CWM I think recovers only the ROM and the kernel but no system applications, any app to do that and save everything to my PC?

As you suggested DRW Backup tool I will probably go ahead and unlock the bootloader, the only thing is now that I'm stuck at the backup point,
Before flashing the ROM or any kernel they say "backup", and it's used CWM or other tools, and when you go to install CWM they say backup first before installing...
Am I missing something here?
It's like a loop but no solution on how to backup what it's currently installing before putting any CWM or flashing a kernel...
How did you get out of this?
hey mate first of all backup ur TA partition....then unlock ur bootloaders.....then u can flash any custom kernel with CWM recovery......from recovery u can flash any custom rom or mod .zip file.....
UNLOCKING ur bootloaders voids ur warranty so always make a TA backup before unlocking.....u can search various thread for root,unlocking bootloaders,flashing custom kernel,custom roms within the thread.....
Hope this helps.....

There are two different flashtools out there.. Use this one: http://www.flashtool.net/index.php
Which .ftf did you try to flash?
Did you install the needed drivers on your pc?

What do you mean by hard bricked?
Are you able to run fastboot or flash mode?

Hi guys... i need root mi ZL whit firmware 10.4.1.B.0.101 but not as... i need help
Sorry for my bad bad english :crying:
You have two options
1. unlock your bootloader and flash root(warranty, DRM keys lost)
2. downgrade to 4.2.2 firmware
backup TA partition then flash a 4.3 pre-rooted stock rom
lastly restore TA partition(must be stock kernel)
stock rooted phone with warranty and DRM keys
If you don't care about the warranty, I'll suggest just go with option 1, since option 2 might be time consuming.
Option 2 is always better. Who knows when your phone is going to break.

Not the OP, but am trying to figure out how to do this. All the root threads are a year old, so I want to make sure I have my facts straight before messing anything up. I have a C6506, US Generic but I don't want to lose my DRM keys or Warranty for resale reasons, so am trying to do this the "locked bootloader" way.
1) Downgrade to 4.2.2 firmware. Do I do this with Flashtool? This doesn't require unlocking the bootloader?
2) Root it .. Doomlord method? The Flashtool website says it can "root", too, but it offers no details on which method. What's the best way to go?
3) Install custom recovery. Which one? I see Nut's thread all talk about a dual recovery, but is that necessary? Can I install just one?
4) Is there a pre-rooted 101 for the C6506 US Generic? I can't seem to find one...
deleted (doesn't work with .101)
CokeJunkee said:
If you're on .67 or .101 firmware, just flash the .423 kernel via Flashtool.
Because it is a Sony stock kernel, you do not need to unlock the bootloader for this step.
When flashing is done, close Flashtool and reboot your phone.
Enable 'unknown sources' (found in security settings) and 'usb debugging' (found in developer options).
Now use Doomlord's method to root.
When rooting is done, it's time to install a recovery to your device.
If your're going to use a custom rom based on Sonys stock fw (like ExistenZ and RomAur), I strongly recommend using [NUT]'s dualrecovery.
AOSP roms (CyanogenMod, P.A.C., Omni, etc.) bring their own cwm recovery.
After root and recovery, turn off the phone and flash either .67 or .101 kernel, corresponding to your firmware.
Now it's time to backup the TA partition.

This is extremely helpful - thank you for providing links. I am wondering why this is so different from the method laid out here:
http://forum.xda-developers.com/showpost.php?p=51612704&postcount=12&nocache=1
Seems like your version is much easier, so I wonder why someone would go through all that trouble for the same result...
Also, won't I lose root once I flash the .101 kernel? Do I get it back using recovery?
Also also: the kernels linked above are for C6503 and C6502. Can I use the full FTF files for C6506 and just deselect flashing everything expect Kernel? It looks to be the same files, except that rpm.sin is included in the full files and not in the kernel FTFs.
when i flash a .423 kernel i got bootloops, am i doing something wrong?
after flashing back the .101 it boots normal

The catch is, flashtool (0.9.16.1) can't read any of the ftf files I put in the firmware directory..any idea ?
Did I get the steps in the right order, is there any way to achieve this at all ?

maybe file is wrong download here a new one. this works 100% LINK
also use normal flashtool not 64bit.

install android sdk (just leave all like it is & press install)
now to the process:
flashing a generic ftf to debrand my phone, in orded to unlock the bootloader i dont think this is need. on sony bl unlock site theres mentioned how to get in service menu & look if bootloader unlock allowed: yes or no. if yes just proceed. any way, CM requires flashng stock ics ftf b4 so do it after unlock...
install recovery no need if you flash CM's kernel later it was recovery built in (all custom)
unlock boot loader
flash cm kernel via fastboot
flash CM dont forget gapps! (google apps)
