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.
You're device should now be bootloader unlocked

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.

I see.
Well I tried with flashtool it denied unlocking :silly:
I think it would be better to go with the official unlocking.
Thanks.

u should add the TA Backup guide also

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.

Guys where is the relocking guide?? I can only see the unlocking one.

Here are device files for Flashtool with loader.sin file for success bootloader unlock/relock through Flashtool
C190X C200X
1. Unpack it to '/Flashtool/devices/' folder
2. Run Flashtool and select in 'Devices/Manage/Import' M or/and M Dual
3. Now your can use BLU button

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

I have a question...
How will I be able to backup my TA partition if root is required? I have not yet rooted my phone. I only rely on official procedures because I have bricked my two other phones previously. Have you had root installed on your phone when backing up TA partition?

[Q] Question about lock bootloader

Hi All
When I bought my XM the fw version was .17.
Before unlock booltloader i was made a backup on TA partition.Then i was made ftf file with my stock firmware but yesterday i lost it
My Q is ,if i flash another firmware version .17 ,then can i restore the TA partition and relock BL again,or this can be make only for FW from who i'm bakced up TA partition?

I may be wrong, but you can relock your bootloader in any firmware, but if isn't the same version from when you did the backup then your phone will stuck in a bootloop after relocking, but if this happens, just use Sony Update Service to restore the correct firmware and get the phone working again after relocking...

Mhm only must be on stock kernel,thats right?No matter the fw version(.17 or .8)?

[Q] Root firmware .101

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

Backup TA partition
Unlock bootloader
flash last lollipop by flashtool
Flash kernel kitkat via flashtool in hotboot mode (fastboot option for flash) (provide by you)
when phone reboot, push volume - when led flash
flash superuser (or nut's dual recovery) by recovery after choose fix su before reboot
hard reboot phone (power + vol +)
clean your phone
relock bootloader
reflash TA partition
all file for root or dual recovery here : https://mega.co.nz/#!ZdARCSIB!p1bSDiYls1cwIve-qC4qdxuXYU0Ilt9pMJPL_z7-qhA
all work fine but not flash boot.img by fastboot directly
TEST ON LOCKED BOOTLOADER MAYBE WORK IT
Or reflash stock kitkat with flashtool and exclude userdata and cache
or reflash an lolillop and exclude user data also

Thanks for your concern.. But could you make it more simple?!!
And another question can i restore the lost data?!!

in some linux distribution your are a lot of app for restore lose data, but I don't think it work with mtp devices (is is your android data sms, app, call log, it's impossible)
and for update lollipop if you are lost your data, flash simply with flashtool...

Question is - If I downgrade from the latest .253 Marshmallow to .170 Lollipop using Flashtool; Will I lose my DRM key?

No, downgrading doesn't lose DRM keys. Unlocking your bootloader does.

Oh that's cool - good to know
Not sure if you'd know...
Lastly is it true that if you downgrade from Marshmallow to Lollipop you will get into a bootloop?
I read it on one of the posts when I searched... Unless that person did a dirty flash then that's a different story all together.

The causes of bootloops are varied and many. Having said that, I can't seem to recall whether the Z5P ever had LL. Good luck.

hello flash with flashtool with full wipe you have bootloop ?

Bootloop only happens when i flash .200 and below. Yes full wipe and exclude partition,system and TA. My firmware now is .253 i can only downgrade to .224 without bootloop happening. since the ivoryroot requires .200 i can't backup my drm properly.

Well, this is strange, yesterday i have succesfully backup my drm keys on my E6853, but first i upgrade to .253 only to realize that iovyroot can't backup my keys, but there was no problem to me, i downgrade to .170 and backup my keys and then unlock the bootloader and install romaur, so the firmwares i use are this:
first the phone came with 32.2.A.0.224 / R5C Telcel GSM MX then i upgrade to 32.2.A.0.253 / R11C Customized NOBA and then downgrade to 32.0.A.6.170 / R7B Vivo BR
