[Q] Unlocking Bootloader & Removing Sim Lock

Hey guys my cousin gave me his Xperia X8 to remove the SIMLOCK from. Its an Xperia X8. I found this guide however the programs included arent working for:
http://forum.xda-developers.com/showthread.php?t=1436957
It says that the phone must have manufacturing code 11W28 and below and the Xperia X8 I have got it 11W22
It says run s1tool and click DO JOB. However the s1tool has been updated and when I click identify and connect Xperia X8 when turned off as well as pressing the back button nothing appears within S1Tool. So I cant continue the remaining steps.
The phone is not unlocked and runs stock SE Firmware.
FYI: I am trying to unlock the bootloader and then remove network lock. Im just saying this so you clever guys know what my objective is
Thanks in advance

Is it possible to unlock the bootloader on a network locked phone? I also have the X8 and apparantly I cannot unlock it's bootloader.

Yeah, its possible, you should try it

You can safely unlock the BL on yoyr phone. Here is what you have to do in order for S1tool to read your phone properly.
1. Install the Flash mode and ADB drivers for your phone. These drivers are bundled with Flashtool, just download and install Flashtool (link in dev section) and then go into the drivers folder and install. Then reboot your computer.
2. Turn off your phone. Then go into S1tool and click identify. Press and hold the back button while connecting your phone to the computer via USB cable. A green led light should appear to indicate that your phone has entered flash mode. S1tool should then start identification.

Hi guys, can somebody confirm that if I unlocked my phone by Omnius than if I unlock it with S1Tool then it will work? There are a lot of discussions about this on the net but it is not clear. On many sites written that I will lose the network signal or the radio if I do it...or the sim-lock will be restored again...So if somebody know this please write a clear answer for example:
Yes you can unlock it with S1Tool without any problem or
Yes you can unlock it with Omnius without any problem or
No because...
Thank you very much!

I just damaged my new XZ

First I unlocked bootloader with DoomLord method. Then did root. Then for same stupid reason I decided to relock it with flashtool for ZX beta2 and it didn't booted. It vibrates when i push the power button, but nothing appears on the display. Then I did the unlock and root procedure with fastboot on SDK and the phone responded to be connected and commands succeeded but nothing appeared on the display. Please anybody help. What I need to do? Fastboot seems to work. When i plug in to charge the red led does not stay on - it blinks

Can you flash a firmware with flashtools?
Do you have enough battery?

Close flashtool. Then download and install EMMA (official Flash Tool for Xperia devices) from Sony (https://www.google.ch/#hl=de&safe=o...le+emma+download&oq=sony+mobile+emma+download) and reflash your device with it.
Pay close attention to the instructions on the download page as you need to copy a couple files around before it works.
You need to boot to bootloader mode to flash. This achieved by totally turning off the device and holding VolDown only (not power) while connecting it to your pc.

Now I succeeded to connect phone to EMMA but it says locked phone. As I used relock option on Flashtool beta2 now how can i unlock it again? I tried DoomLord method and it gives me error write 'boot' failed. I did also the unlock process from Sony mobile provided and in the command window it says 'okay finished' but bootloader is stil locked

Excellent so far, helps narrowing down the problem.
EMMA only flashes unlocked devices, I figured you are unlocked so I recommended EMMA.
If you're locked, simply get Sony PC Companion and do a "repair" with it. Run PC Companion, boot up the phone, connect it, once PC Companion says connected click "Update firmware" or so. It should then say you're on latest firmware already and asks if you want to perform a "repair". Do so.
Just reread your post. Your device isn't booting, then of course the above doesn't work. You may try, I believe PCC also works with a device in flashmode.
However, you may also download SUS http://www.sonymobile.com/gb/tools/update-service/ and try with that. Its the counterpart of EMMA for locked devices.
Shut down your device (hold VolUp and Power for about 15 seconds, the device should vibrate 3 times in a row). Start SUS, select XZ and when it tells you to, connect your device holding VolDown ONLY. It should then do it's thing.

The unlocking and rooting part is not that scary as long as you have no power outage
The problem here was the relocking of the bootloader, there is no known way for that, yet.

I got my phone back thanks to schaggo .
SUS preinstalled it which means that it had been properly locked with Flashtool beta2.
But then no way to unlock again as I tried both ways known here as EMMA asked me to do.
I've rooted my previous X10i and my chieneese tablet wm8650, installed custom ROMs many times
but when I saw the black screen on my brand new XZ I just freezed, couldn't make my brain working.
Now curious about the BE - is it lost with the first unlock or it's back now?
There were some demo videos and music which are gone now and maybe this means BE is no longer working.
I wonder if there's a way to port back BE as FeraVolt did for one of his ROMs

So is your phone locked now?

Yes, its lost with the initial unlocking of the bootloader. Maybe it will be ported, maybe not, no way to know at this time.
I still miss an information: yours is locked now, ok, but could it be unlocked again (unlock allowed:yes vs. unlockballowed:no)?

He already lost BE, DRM and stuff, why limit one self to the less convenient dealing with locked bootloader when an unlocked device offers more flexibility and ease of flashing?
Flashtool for Z beta 2, replace x10thingblah.jar (search flashtool thread), hit relock button, reflash stock with PC Companion/SUS/Flashtool, done.

I have rooting status : unknown
This was said to be a bug - already fixed I think
I haven't tried unlocking again because I'm not sure that yesterday's death of my phone is caused by the relocking
I'm gonna wait and stay on stock for a while to see if this phone works without any problems.
About the BE2 I really don't know what to think : I did some screenshot with XZ on/off and there's no difference.
Then did the same with X10i (FeraLab' s ROM with BE ported) and again didn't find a difference between all of the screenshots including XZ'

Maybe it doesn't work on your X10 either. On my Z, I can make out a difference, especially with the provided stock images, which are VERY colourful on purpose I suppose, to demonstrate the oversaturation of colours BE2 produces
But I may ask again:
1. you reflashed your phone with SUS or Flashtool
2. after the flash you did not root or try to unlock again
3. when checking now (fully stock) your unlock status is "unknown"?
I ask, because root with locked bootloaders also makes the status unknown.

ive got my phone stuck on the sony sign instaling a custom unlocked bootoader rom when my phone has locked boot loader any help atall
i had root and everything was working but after install it said to fix permissions when they were fixed i rebooted but its stuck on sony sign.
any help would be gratful.
do i need emma flash tool ? still waiting for the email so i can use it

I tried many ways, including restoring everyting with PCC, fully original stock without root, without unlock, but it still says "unknown".
Again, unlock with flashtool 2beta, OK says "unlocked yes". and relock again, "unknown", and unlock again, "yes", switching freely...
Whatever I do, BE2 is dead, forever.
Somehow there is only one thing for now, with the fake relock "unknown", PCC or US or even OTA can accept device updating or restoring.
So to get BE2 back or get "locked" status, we'd wait for devolpers to work out something.

The Japanese devoloper way of locked root will make the status "unlock not allowed", whether device locked or unloced, which is just false information, don't worry.

[Q] How to check if the bootloader is unlocked.

Hi there.
After i unlocked* the bootloader of my phone i got stuck in a bootloop, then i had to flash the TFT all over again...
The problem is that i don't know if the phone is already with bootloader unlocked or not...
how can i check it?
I was thinking on trying to do the unlock steps again, but i'm scared of being trapped on another bootloop...
Is there a way to check if the bootloader is already unlocked?
PS: The bootloader unlock allowed is yes.
thanks you guys.

Flash doom kernel via fastboot with this command:
Fastboot flash boot boot.img
If you get an error than your bootloader is not unlocked.
You can flash back to stock kernel with flashtool,flash the kernel separately.
Sent from my C6603 using xda premium

but if i got that error and confirm that the bootloader is locked, is there any chance to harm the phone? or need to flash the TFT again, etc etc

use flashtool to tell you

Another more easy approach .
When bootloader unlock allowed says yes and be2 is working in Album, then it is still locked and you can start the unlock steps again.

How can i use flashtool to tell me?
@DevShaft
Before i could see in a flash the bravia engine working on pictures. There was a little delay... Now i can't see it.
Probably the bootloader is unlock.
If i try to install Doom's kernel via recovery and the bootloader is LOCKED, can it do any harm? thanks guys

But not picture enhancement in album right? Hope you backed up TA partition before unlocking

im surprised at how this 'check bootloader is unlocked already or not' thread is confusing.
by the previous post, there is two 2 ways
1. try to flash doomlords kernel via fastboot, and if it doesnt flash means its NOT unlocked.
2. flashtool.
however the 2. flashtool method is very vague.. dont think anyone elaborated it.
So my same query is that if some error occurs after trying to unlock bootloader, and have reverted back to the stock FTF rom in original working state.
How do one check to see if my bootloader is unlocked or not?
whats the best easiest method???
Thank you!

just type in *#*#7378423#*#*
Go to Service Info > Configuration
And check the Rooting Status
If its Bootloader unlock allowed:Yes/No, then its not unlocked.
And if its Bootloader unlocked:Yes, then its unlocked.
Thanks

That just tells you weather you can unlock your bootloader via the command / flashtool e.g. If you carrier has locked your phone
On a unlocked bootloader the BE2 engine still works on videos ect just not pictures.
All I would do Is flash doom kernel or advanced stock kernel via flashtool (Click on lightning bolt /fast boot / click on put device in fastboot via adb now phone will enter fastboot then select kernel to flash which is in the middle on the pop up screen and then flash if it will take around 0 . 5 seconds ) if it fails then you bootloader is locked due to it cannot complete the command if is successful then it's unlocked and you can flash custom kernels take about 2 mins to do all in all

Unlock bootloader without losing DRM keys
Hey guys
I have a similar problem. I want to flash DoomLord's custom kernel but the command is not allowed. I found out bootloader unlock allowed does not mean it is unlocked yet, so that is the problem why it is not allowed. However, I do want to backup my DRM keys first. Is this possible? My phone was rooted before I flashed 4.3, so it is not rooted anymore.
Oh I have a Xperia Z 4.3 c6603 flashed with the ftf supplied by doomlord.

u welcome!
just checked the screenshot says that BL unlock allowed: status YES which define that ur BL (bootloader) is not unlocked yet!
make sure u are using the appropriate tool that works for ur device after u get the BL code from Sony, then follow the instructions in Sony where u got the information about unlocking BL
first off... do not proceed with bl unlock until you backup your TA partition cuz u might brick ur phone after the unlock is done if something goes wrong!
is it's not really recommended... u can still root it with a locked bl and enjoy ROOT privileges... FYI, unlocking bl will erase DRM keys and might affect on ur TA partition too.... so keep in mind that Bravia Engine2 along with Track ID will stop working after unlocking ur BL

ok this might be a bit too many questions

hi all,
i have recently aquired Sony Xperie SP C5303, and i now i'm lost since i never had android phone. all i used was various emulators for PC and stuff...
but now there is many stuff to be noisy about. and probably this has been answered many times but please, do me a favor and pretty please answer again if possible.
1. Phone is SIM locked (i'm working on getting unlock code from provider, since i have right to do so, after contract expires..which has)..but is there any way to unlock phone before i get the code? i'm wondering how technitians in local services do that. they ask about 30€ for unlocking device, and i doubt they have acces to provider's unlock code.
2. I tried to flash phone with custom firmware (using flashtool) but it failed on me even though i used right firmware, and phone bricked. however i managed to recover phone with sony PC companion and it now works same as when i got it. Firmware 12. 1. A. 1. 205, android version 4.3. i have no idea why it failed on me during flash. can it be cause phone is no rooted, and have no root support? (whill connect to this on 3.) do i have to root phone before flashing? i would really like to have root access.
3. i was unable to do hard reset of phone with power + volume down button. or any other trick didn't work. i couldn't not enter android recovery options. i followed instruction on how to root my phone on
Code:
developersonymobile(dotcom)/unlockbootloader/unlock-yourboot-loader/

to check if my device is unlockable, it says boot loader unlock allowed : No. Does this mean i won't be able to have root acces on my phone? or i still have to learn difference between terms or what they mean.
also is that really true what they warn about that there is no turning back after i root phone and all. won't just hard reseting phone or repair device with all defaults troubh pc sofware bring back and vipe everything back? how will than service know if phone has been rooted ever?
thank you in advance for all your answers.

"Bootloader unlock allowed : No" <= this means you can't use UBL ROMs or custom kernels.
You can always root and use LBL ROMs though. There are plenty of LBL ROMs out there to try.
You can always un-root your phone. And you can always repair your phone's OS by flashing the Stock ROM via flashtool. Doing so would remove root access as well, no one would know you ever rooted.
Root using towelroot.
Get recoveries by Dssmex.
Then flash LBL ROMs, mods, ports etc. that you want.
and Be careful when you flash anything,
Read the threads, don't try to flash any UBL ROM as it may brick your device.

First thank you for helping.
UBL is unlocked boot loader right? and L is locked. sorry to doubt your last tip but i need to double check was it typo or...? you said don't flash UBL. isnt that supposed to say don't flash LBL. or i have totally got this wrong. maybe i don't know what what's LBL and UBL.
but just to be safe? where can i find stock ROM? i tried official site, they don't let me download firmware manualy. only trough sony PC companion automatic repiar. Which is ok too i guess. else i can download sony flash tool callsed emma, but i cannot get login info since they need about 7 days to approve my registration.
so my first step is to root my phone. ok i will do that. i might do it manualy, not trough application though.
what about sim lock? after i root phone, is there sim unlock command or what? and do i need code...how do you unlock your phone to be able to use other SIM.

Welcome.
And no, I did mean "Don't flash UBL ROMs"
UBL = Unlocked Bootloader
LBL = Locked Bootloader
The ROMs that are made for Unlocked Bootloaders are UBL ROMs.
Unlocked Bootloader users can use both LBL and UBL ROMs.
But since your device's Bootloader cannot be unlocked, you can only use LBL ROMs.
It's written in almost all ROM threads if it's a LBL or an UBL ROM. But if it isn't specified, then be sure it's UBL. (Like all 5.1 ROMs are for UBL)
Download stock ftf from here.
Use Flashtool v0.9.18.5
and I can't say about the last one as I don't use a carrier locked device.
Try and see what happens.

thank you again for reply. you've been very helpfull with all info.

that is exactly from where i got it the first time. also same flashtool version. after i tried to use that firmware, my phone bricked.
even though it's stock ROM, probably cause my phone had locked bootloader (i finally found article on what is bootloader and i got it now).
but after this, i have used sony software to recover my phone and it works again.
now important stuff. so my device's bootloader cannot be unlocked. does that 100% means that i'm stuck with locked bootloader and no way of getting it unlocked.
even on sony offical site there is process tutorial how to unlock bootloader, and it says "if you device isn't listed, than you cannot unlock bootloader".
but it IS listed and I AM able to get the unlock code for it. now i'm confused. can i still do the process showed?
another confusing thing is where i read about bootloader, it says that for to be able to root i need to flash custom ROM, and to do that i need to unlock bootloader.
but you have provided link for "towelroot" which was able to get my phone root acces. is it different from rooting my phone manualy after unlocking bootloader. how did it manage to root it anyway? and with towelroot it still has bootloader locked. actually it says "boot loader unlock allowed: NO!". now begs the question does that mean, not allowed, but i can be unobidient one and still unlock it without clearance, or does it mean .."you're stuck with locked bootloader. deal with it!. if you try to unlock bootloader your phone will brick"!.
i think after i get answer to this, than it would be my last question for this topic
also again, thank you for answering all previous questions...and this one, hopefully

Did you install the drivers properly (Flashmode, fastboot, viskan common) ?
You need to disable driver signature verification before installing drivers if you're on Win 8/8.1/probably 10 too.
And flashtool should work perfectly in both LBL and UBL phones.
You said your service menu says, "Bootloader unlock allowed : No"
Even if you get a BL unlock code you can't unlock it coz it's not allowed.
And by messing with the bootloader or trying to flash UBL ROMs may permanently brick your phone.
And different phones have different rooting processses. Rooting our SP is easier than most other phones by TowelRoot.
And "Bootloader unlock allowed : No" is more like a "You're stuck with locked bootloader. deal with it!. If you try to unlock bootloader your phone will brick!".
And you can still use a lot of LBL ROMs, from 4.3 to 5.0. So don't worry Lol.
Welcome

i did install fastboot and drivers and everything acording to tutorial. i payed attention on par "pay attention to this. be sure to install drivers correctly, lol"
i'm using win 7 64bit sp1. i have disabled UAC. i'm alaways running as admin. as for flashtool. software works perfectly..it just fail flashing.
it goes to part where i need to unplug phone and plug in holding volume something button..it says on poppup. than i plug in phone and it starts flasshing..it goes up to 40% something percent. if finish few files but when it comes to system.(something) i forgot extension, it says failed. flasshing stopped. than after that i can't turn on phone again.
i couldn't untill i recovered via Sony PC companion. i did try to flash it several times with several roms. i think it's cause my provider messed with bootloader. they locked it together with sim. on official sony site. it says:
"Note! Even if your device is listed here, certain releases of the device model may not be supported due to operator restrictions. Please select your device on the Start tab to check if your particular device can be unlocked."
anyway, i even got my provider's firmware trough flashtool download system, got my provider's name and exact same firmware that was installed. it still failed on same file.
than after i recovered i didn't try to flash anymore. i don't even know what's the point, if i can have root access without it.
i'm not so keen on installing other android version, unless this one gives me problem. for that i need to unlcok phone first to be able to even use it or test it so far it's has been t urned off most of the time

I see.. I'm not actually sure why Flashtool isn't working.
Anyways some good 4.4.4 LBL ROMs are 'CM11 by Bagyusz', 'Omni-X by NeildownX', PA etc.
Try them if you want.

I assume you're now on a rooted stock ROM.
Follow this to get recoveries.
Reboot, when you see the Blue LED burn, press vol down to enter TWRP recovery.

can i use cm-11-20150822-UNOFFICIAL with flashtool so i avoid installing recoveris or CWMP?
flashtool worked for me it just gave me an error during flashing one of the files....that might be cause i didn't know difference between LBL roms and UBL roms. maybe problem was incorrect rom type for my phone.
i tried to install recovery tools. and i had some problems...when i swhitched on phone there was no light showdown,,just red led...and after phone entered safe mode. but not in recovery menu.
i sure have no idea what to do...now everything is so strange.
to be honest i'm considering dropping this whole thig of and use stock rom as it is...
it would be cool if there would be automatic debloat application which will remove all bloatware...
or at least bloatware list of apps i can delete manually, without loosing important function on my phone. than i would not need custom rom!

If you're on CM11 by Bagyusz, Open Terminal Emulator and enter the following codes,
su
./system/bin/recovery.sh
^ it will give you access to recovery when you see the red LED while booting.
If you decide to go back to stock, you can freeze/remove these apps.
I made the list when I was on stock. Take a backup before removing them just to be safe.

thank you a lot! this has all been so helpful!
