hi guys this is just a guide to unlock bootloader easily by using flashtool on All Xperia

first I'm not responsible for bricked phone

remember there may be full data reset on unlocking bootloader

if want to unlock follow bellow step

Its Better to take TA BACKUP[so that you can relock your bootloader and claim your warranty] http://xdaforums.com/showthread.php?t=2292598

Download flashtool : http://www.flashtool.net/download.php

Steps:

First you should confirm that it is possible to unlock the boot loader of your device by checking the service menu. In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.

In your device, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

go here http://developer.sonymobile.com/unlockbootloader/ and select your device and click continue

now type your mail id..and tick agree the terms and condition on that page and click submit

open your mail...see the mail from sony..it will have a link.. open it

now open flashtool click BLU icon...and then connect your phone on flashmode by pressing and holding volume down button

and after sometime it will show another window to unplug phone/..

unplug phone.., press and hold volume up button[Fastboot Mode] and connect the phone to pc again

now it will ask the code...

copy the IMEI from flashtool and paste IMEI on the link you opened from mail and tick two agree the terms and condition and click submit

now again open mail....Check your mail,it will receive a mail from Sony with key...

copy the key code in ur mail and paste in flashtool...Then click Unlock..

thats it ur phone gets unlocked and if it restarts...pull the battery out and flash the stock rom again...

[NOTE1:while unlocking if u got errors..close flashtool and open it]

[NOTE2:After you unlock bootloader.U cant flash other device roms on your device..it will hard brick your phone..please use kernels,Roms made for your device]

Only root is required. You don't have to unlock the bootloader.

You can't if you don't have a backup of YOUR TA partition.

And how are you trying to transfer them? I swapped sd and Internal. Link2sd doesn't work for me.

yes i full rooted the phone

link2sd dosen`t work and not installed

[Sony Xperia M] Antrikos48:
Sone people got gl2sd to work. You can try that or foldermount.

[Sony Xperia M] zepllin:
tnx

but i don`t know how to use folder mount ????
[Sony Xperia M] Antrikos48:
Mount each of the folders in Internal/Android/obb to the sdcard. The large files are saved there.

You can also try unlocking your bootloader or applying the definite reboot-remount fix to get link2sd to work.

[Sony Xperia M] ansebovi:
GUYS link 2 sd works please reformat ur sd 2nd partition to fat32 and reboot phone then mount script in link2sd...it works..

please see general or here

Someone just confirmed link2sd works with ext3. Gl2sd works fine for obb, like foldermount.

Hi, can i use this for my Xperia M dual C2005 with new Firmware 15.2.A.2.5?

Thanks
[Sony Xperia M] ansebovi:
ya bootloader can be unlocked

ur warranty of phone will be cancelled
[Sony Xperia M] RAD7:
Of all people Motorola who have been so far most developer unfriendly have now announced that they shall honor warranty for developer unlocked BL phones as well as for folks who had done earlier unlocked their BL.

Can anyone advise what is the timeline for receiving the BL unlock code from Sony? Also since it is my Dad's phone I am not gonna be unlocking the bootloader until warranty expires however to be safe I was thinking of getting and keeping in record the code from Sony in case they decide in near future to stop issuing unlock codes. My question is (if anyone can advise), is the warranty void only if I actually execute the unlock process using the received code or is it void even if I merely request and get the unlock code from Sony??
[Sony Xperia M] cooler567:
Hi, thank you it works, now how about CWM recovery for new firmware?

i can't find it.

thanks before:laugh:
[Sony Xperia M] ansebovi:
what do u mean timeline?

they will give the code in a instant u give them ur imei number,..it will be sent to ur email account..

i think warranty only voids after u unlock the bootloader of phone...[receiving code wont void]

http://xdaforums.com/showthread.php?t=2494793

here..
[Sony Xperia M] RAD7:
By timeline I meant how long it takes for the code to be received (had read somewhere in the forum it was taking time to receive the code and hence I asked). Noted it is instant. Also noted your thoughts about merely receiving the code not voiding warranty. Wish could know for sure what Sony's policy is on the same. Thanks though.
[Sony Xperia M] ansebovi:
many says if we relocked bootloader with restoring drm keys,ta partition,,,the warranty will also restored...so the code is not important i think...the TA partition and DRM keys are important i think...u can google it...backup of TA partition for xperia
[Sony Xperia M] RAD7:
Oh yeah, I am aware of TA,DRM backup & relocking the BL and indeed it is a good advice. Just that don't know what Sony, India in particular policy is regarding keeping warranty valid once after a customer has merely requested for a unlock code. On my earlier interaction on phone for some other query they issued me a reference number on which they were supposed to revert back to me but which they never did, it clearly shows their indifferent attitude towards Indian customers. Thanks again bud.
[Sony Xperia M] darekesp:
Maybe U made a tutorial for M single ?? Flash tool wiping all data after unlock ??
[Sony Xperia M] andro-SYR:
M single supported by default in the latest flashtool, and sure unlocking bl will wipe ur data

Thank's ... 2011 line was easier to unlock
[Sony Xperia M] alvinhochun:
It's just the exact same method using fastboot, The OP uses flashtool but you don't need to.

Unless you mean the testpoint method is easier.
[Sony Xperia M] darekesp:

[Sony Xperia M] craigibhoy:
Can someone help out a little, on the sony official site about unlocking the bootloader theres instructions and i visit my phone to see if bootloader can be unlocked it says no, so why can some people with xperia m unlock bootloader but i can't same models. ? or does this bypass when it says it can't be unlocked ?
[Sony Xperia M] sunny54_8:
maybe sony forgot to add your phone's ub code on their website lol
[Sony Xperia M] ansebovi:
dont come and make fool of others...help if u can...if u cant..please be quiet

maybe bcoz of network carrier or the country u r living in...

if its bcoz of carrier..then u can unlock by asking them by paying them...

if it says no...then u cant unlock with official method...

any suggestion to resolve this?

thank u all

[Sony Xperia M] AhanDev:
Go to the Sony web page and ffollow the steps to unlock bootloader u should be fine

Can't find web page search for

Bootloader unlock Sony mobile

The website should appear cheers
[Sony Xperia M] mikee286:
Is there any way to tell before buying which units have a hard locked bootloader? This is one of many questions I have about this phone before I decide to buy it. I don't want to have to return it if the bootloader is hard locked and I don't think the store will see a hard locked bootloader as grounds for a return. The one I am thinking of getting is the PC mobile xperia M on prepaid in canada.
[Sony Xperia M] ansebovi:
most phones can be unlocked..but if u buy on contract with carriers..u will need to pay amount to unlock..or its permanently locked...
[Sony Xperia M] mikee286:
so to unlock bootloader all you need is to have the phone unlocked from the carrier? The one I am thinking of getting is on a prepaid service but still locked but my last phone I got on this service I was easily able to unlock on cellunlocker
[Sony Xperia M] ansebovi:
if u r getting in contract carriers like o2,verizon etc etc...there would be those 2 happen..[there are many contract carrier..each having their own methods to unlock]

but if u just bought a phone separately and then u insert sim,..u will have unlockable bootloader...

So I bought one of these phones and managed to hit the "Bootloader Unlocked Allowed: No" version...

I've spoken with Vodafone (and paid the money to SIM-Unlock hoping they would budge) but they are not helping out.

Has anyone tried testpoint with the Xperia M (C1904), or would it be a futile attempt to unlock the BL?

Thanks.
[Sony Xperia M] D.Sirakov:
Does it work on 4.3 ?
[Sony Xperia M] snyp3r:
Currently on Jellybean 4.3

How do you mean "working or not"?

It's been updated via the Sony PC Companion and yes it is working.

I am still unable to unlock the bootloader as per my original post.

Hi mates, sorry for ask even if says xD.. but i wanna check in case, there is NO WAY to do it if says "No"? :confused:, damn, i wanna cry.. xD jaj Thanks and sorry for the bother..:eek:
[Sony Xperia M] Erix_code:
hi , thanks for the share , well i have xperia M dual (c2005) , since i'm linux user i unlocked it's bootloader using these steps :

i checked using the *#*#7378423#*#* and it said "YES" so i enabled debug mode and power off the phone connect cable to linux box holding "Volume up" and the light turns to blue so i figured i'm in fastboot mode the i proceed like this:

in commands : "fastboot devices" it gives me device ID

then : "fastboot -i 0x0fce oem unlock 0xCODE_SONY_GAVE_ME"

and i got ok! (all steps were instructed in DevWorld of sony website)

then i unpluged phone and powered on the device ! it Gives me SONY and Xperia logo and stuck on the colored waves!

did i brick the phone?

how can i repair this mess!

by the way i tried steps in this page and now flashtool says :

Your phone bootloader cannot be officially unlocked

You can now unplug and restart your phone
[Sony Xperia M] FindYanot:

[Sony Xperia M] kkx17:
my phone getting bootloop, is my bootloader still locked or its unlocked?
[Sony Xperia M] dastan4eva:
Well its common to get boot loop sometimes after unlocking which you can easily fix by flashing back stock via flashtool. Try to hot boot a custom kernel and if you see the the pink (blue) led your bootloader is unlocked

Also there is a service menu you can access via entering a certain code in dial pad (Google the code) check if bootloader unlock says yes in it, though am not really sure if its reliable
[Sony Xperia M] gamer649:
The code is *#*#7378423#*#* (*#*#SERVICE#*#*), then under Service Info>Configuration>Rooting Status: the bootloader unlock allowed string changes from Bootloader unlock allowed: Yes to Bootloader Unlock: Yes, indicating successful unlocking of the bootloader.
[Sony Xperia M] Remorcer:
There was this shady myth that if you unlock your sim lock and reflash an unbranded firmware, it'll change to yes, if you do try it, please post any results here
[Sony Xperia M] dastan4eva:
Can't the carrier just unlock it if they're paid [emoji15]
[Sony Xperia M] kkx17:
Its unlocked, thanks

but it is still possible to make a TA backup now? This is my first unlocked bootloader xperia M 4.3 firmware, because I think that TA backups on 4.2 and 4.3 are different, is that true?
[Sony Xperia M] Sh0m1:
Nope, TA backup works only before bootloader unlock, after unlocking it you can only restore the TA backup of your current firmware.
