Hi!
I've tried to modify my x8 and after flashing my radio in it is broken. Everything else works fine. It was after I unlocked the bootloader with msm7227 tool. SEUS does not work, even after flashing with Flashtool and generic 2.1. Is there anything I can do? Step by step tutorial would be nice. S1 tool shows NOT RECOGNIZED SIM CERTIFICATE. The phone had no simlock earlier. I'm counting on any help.

Use SEUS "Repair" option to restore radio functionality on your phone. As I have mentioned in my guide, it is best not to unlock the bootloader on your phone if you had the "NOT RECOGNISED SIM CERTIFICATE" message.

SpyderX
P.S. Wrong section to post this btw
I used SEUS "repair" option and nothing. Maybe if I had branded firmware as it was? What do you think? I could try to flash it with Flashtool and then try with SEUS again.
Nothing
Hi all, im having one kind of a problem, me and my friend, have tried to unlock his x8 Bootloader, and i have search and saw the hard brick warning, and checked the device says 9w12 so i thought it was safe, and it wasnt, because the device didnt work after using Unlock method.
Now we have Jtaged it using a box and made it work, and everything was fine, untill he tried unlocking using Flash tool, and it said unlocking was ok, but it didnt actually work cuz he couldnt flash nA kernel after. and then his device went off again, so we had to jTag it again with a box to make it work,
Now its back to stock 2.1 and cant find service, it can see the networks but cannot get signal (no service), and i read a lot on that i gotta use SMEC 77727 or something to make it work, but its the same we used to get our device bricked, so any advice plz guys help?
1.Relock bootloader
2. Unlock bootloader with FLASHTOOL not with msm7227 tools.
First time when I unlock bootloader I unlock it with msm7227,but I didn't have signal. After 1-2month I see that bootloader can be unlocked by flashtool. I try unlock bl with flashtool and now I have signal and I really enjoying!

thanks for your response, can u tell me how to relock bootloader, my eyes are bleeing from searching and i dont wanna hard brick the x8 again sir. x(
Use x8toolbox
Also, using 1stools. first time i tired to unlock, it said SEMC SIMLOCK CERTIFICATE, but now it says NOT RECOGNIZED SIMLOCK CERTIFICATE.. what would this mean?
before i do anythign stupid now
That message will change back to original message when you relock..
It's the reason you get no carrier lock.
I downloaded x8tools, but its based on Cmd command line, not sure where to find a tutorial, im looking at the moment to find one

Did you relock the bootloader first using x8toolbox?
No, because i cant open it, everytime i click on x8tools.cmd it open and close, no idea why,,,, do u have IM (hotmail or so) im in trouble really might need the help

OK got ya.. We could do this over IM but it's good for future users with the same issue to see this thread and find a solution.
So let's go..
1: Don't double-click x8tools.cmd
2: Open MS Command Prompt and cd\ to the directory where you saved it. (Desktop is really handy)
3: Type x8tools.cmd into command prompt
4: Let the magic begin!
alright, here what i got:
starting x8toolbox.final . . .
'busybox' is not recognized as a
operable program or batch file.
did as u said, so whats next bro?

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

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.

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.
Is it possible to go back to stock firmware and relock the bootloader after unlocking it and installing a ROM?
I'm asking because of warranty purposes, and I didn't find a conclusive answer in the threads. Would flashing a stock
TFT relock the bootloader? Since I entered the IMEI on the Sony website, is it forever there?
Thanks!

At the moment, there is no known method of relocking the bootloader. Flashing a stock TFT won't change the bootloader status.
This question has been asked so many times
I believe Androxyde is making a relock FTF.
If you flash a stock firmware , the bootloader will remain locked.
Sony may or may not fix the phone for you if the bootloader is unlocked.
What about IMEI logging? Is it logged somewhere that I've previously unlocked the bootloader?

I did that already but not flawlessly.

Flashtool beta2 has a relock ftf file and I used it but the phone didn't start normally - I had to update with SUS
The bootloader was relocked EMMA confirmed also
OP do this:
Download the latest Flashtool
Install the Flashtool drivers
Connect phone in Flash-mode (power down + power)
Press the BLU button
Press the relock option
Put a stock .tft firmware in the Flashtool firmwares folder (this is required!!)
Flash the firmware (this is required!!)

Awesome! But if this doesn't recover the warranty, I don't see many reasons other than BE2 to relock the bootloader. I was just wondering if I could make it look like the phone has never been rooted/unlocked BL, but then Sony records the IMEI, so they can find out..
What are other people's reasons for relocking the bootloader?
Awesome work, btw!

Why do you regret your unlock?
If you didn't want to flash a custom ROM, why did you unlock?
If you did flash a custom ROM, why do you regret it?
The ONLY thing you lost is Bravia Engine v2 and whilst you can already get v1 from an easy search in the forum, I'm sure eventually v2 will also be available as a mod.
About your warranty... It's a very well built phone with a lot of features aimed for durability, I see no reason for it just dying all of a sudden unless you use it very harshly and in that matter it would be a pain for you to get through warranty procedures anyway.

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.

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.

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
