I followed steps as explained in OP, now I get no signal.....I do have wifi connection though. My phone says 'no sim card' :mad::eek::confused:

if your phone unlocked by 3rd-party software other than setool2, do not run anything -
it will disable radio capability of your phone and you will need to unlock phone by setool2 software.
hopefully, mizerable flea and mOxImKo will release something similar for your phone.

ten_tickles, are you sure your phone was properly unlocked and fit the criteria. I think maybe it was a third party unlock and the_laser warned not to do that or you would lose your radio signal.

Only way to 'fix' it would be to sim-unlock your phone again with setool2, which I have no idea if you can just buy it and unlock it or you need a toolbox or whatever. All I know is it isn't free...as of now...maybe the_laser will do something to fix this.

I followed the instructions (which are similar to rooting 2.3) and was able to successfully unlock my bootloader on my X10a.

PERFECT!

ok, a few things to say maybe:

With recognizing the x10 I haven't ment that flashtool is recognizing it as x10, I ment that flashtool recognizes that there is any phone. My flashtool version is 0291 beta and it has asked me which phone I have connected when if recognized the phone. And then I have started the unlocking by changing to the cmd window and starting the process by pressing any key. Then I saw that the cmd for every step killed and started adb again. That's why I decided to close my flashtool window. After that adb wasn't killed and reloaded constantly.

Second thing maybe to say, first I thought that anthing went wrong, cause the usb unpluggeg tone came on windows and the se textlogo disappeard --> phone restarted, but after restart everything was going on I think. Don't know exactly if the command line window told me before or after the reboot that everything is good. And i have used the semc file, not the setool2 one, cause I never have done anything for simunlocking, cause mine is factory unlocked.

Third, if anything isn't working, could you write if you have anytime tried a simunlock and if you have a x10a or i please.

haha, what do you think?? I double clicked the semc bat. The way you open every batchrunfile for windows command line. between, I'm using win 7 32 bit, don't know if this makes sense...

My phone is simlocked to Orange UK. Am I right in thinking I run qsd8250_setool2.cmd NOT qsd8250_semc.cmd?

Also, do I place meflash.dll in the qsd8250 folder or a sub folder?

Cheers
:)

simply download the 7z archive from the_laser, then extract the whole archieve to a folder, go into this folder and don't move any file, simply run the batch file.

the semc bat is for x10i and x10a. But only if you haven't tried any simunlocking

the setool2 bat is for all those have simunlocked using the setool2

for those doesn't fit any of those two critericas, don't try to unlock bootloader

    If you aren't keeping your current device configuration (because of flashing another rom after unlocking bootloader or anything else) the simplest way to unlock is to flash stock 2.3.3 rom, root it and use the bl unlock plugin from latest flashtool



    Hi guys, cause it was asked for, here is a how-to to unlock bootloader without reflashing a 2.1 firmware what means no need of reinstall your current rom after unlocking bootloader.

    In the archive with the unlocking files take care about the following:

    the semc bat is for x10i and x10a. But only if you haven't tried any simunlocking

    the setool2 bat is for all those have simunlocked using the setool2

    if you don't know it, or not sure about, have a look at the 2nd post, there you'll find a tool to test it.

    for those doesn't fit any of those two critericas, don't try to unlock bootloader with this steps/files linked here


    Things you need:

    If you haven't all the listed things on your computer, then first downoad all neccessary files I have listed above before you go on with the guide how-to do it!!

    Please make sure you have enabled usb-debugging in your current rom before starting with this!!


    • flash the azuzu kernel downgrade ftf with flashtool
    • disconnect usb cable, press power button until phone vibrates shortly and immidiatly connect the usb cable again (it is supposed to be stuck at SE logo)
    • start the batch file for unlocking bootloader, cause it says press any button before it starts, it won't start unlocking until you press any button
    • now wait until flashtool recognizes your x10 (if flashtool doesn't do anything, check third post please! thx)
    • close flashtool and then press any button in the cmd window that the unlocking process starts (please close flashtool, instead the bl unlock cmd and flashtool are constantly killing and restarting adb!!)
    • after unlocking is finish you have to flash azuzu kernel upgrade
    • now power on phone to check if the phone is starting after the unlock (if you are using a custom kernel yet with the bypass method and get stuck in a bootloop enter xrecovery and clear dalvik-cache, then your phone should boot up again fine)

    If you aren't seeing the se logo at turning on phone, but directly the custom kernel logo, you were succesfully. If you want to enter xrecovery you have to spam the back button now if the xperia logo appears instead of the se logo.

    TOOLS

    For testing if you are ready for unlocking bootloader or not, use this tool:

    s1tool.7z

    If you can find semc simlock certificate in one of the last lines from the output, you can unlock your bl with the *semc.bat file
    If you can find anything with setool2 in one of the last lines from the output, you can unlock your bl with the *setool2.bat file
    If you can't find any of these two and see instead s.th. like unknown simlock certificate or similar, you can not unlock your bl. In this case, first simunlock your bl with setool2, then check again with s1tool.

    s1tool can also relock your bl if you want to make use of your warranty.

    I did it this way and it was a HUGE success!! :D :)
    To sum up, this is exactly what I did:
    1. Flashed Kernel Downgrade in FlashTool
    2. Disconnected the phone, left FlashTool running.
    3. Ran the unlock cmd.
    4. Pushed Power Button, when I felt the vibration, I immediately connected to USB.
    5. At this point phone was of course stuck at SE bootlogo (2.1 kernel on 2.3 firmware). I waited for FlashTool to "see" the phone. Took a while because my PC (Win7) was looking for drivers. Once it was done, FlashTool saw the phone.
    6. Closed FlashTool and pressed enter on the cmd window.
    7. The phone restarted one time during the procedure (my heart skipped a beat, I admit) but in less than 1 minute, the cmd reported Success.
    8. Closed the cmd window and pulled the battery from the phone (was of course still stucked at SE boot logo).
    9. Ran FlashTool again, selected Flash, chose Kernel Upgrade and when it prompted, I put my X10 in flash mode and the procedure completed soon afterwards.
    10. I turned on the phone, started spamming Back button and entered xrec, wiped dalvik and cache (because I am on goro's kernel) just in case and then rebooted for the last time!!

    Phone was up and running in about 5 minutes (due to the cache wiping, boot was sloooooow). Now everything is good! It was much easier than it sounds!

    Thanks to the_laser and everyone else involved now and in the future! :)

    Installing Flash-and adb drivers for x10 (!they where updated with the 2.3.3 update!)

    1. open the drivers manager of your pc
    2. connect phone in flashmode (without running any program like flashtool, seus or pccp)
    3. check if there appears an unkown device, which wasn't there before (if not go on, if yes read under the line in this post further on)
    4. no unknown device? Good
    5. turn on phone and connect usb cable again and check again for unknown devices
    _____________________________________________________________________________________
    If there is an unknown device, download this archive (it contains the 2.3.3 adb and flash drivers)

    1. In Flashmode is an unknown device: Go to the archive and install the ggsetup-2.2.0.11.exe file you find in there.

    2. After turning on there is an unknown device: extract the archive and search with your pc's drivers manager manually in that folder for the drivers of the unkown device, then they should be installed.

    3. Now check again like I described it above the line for unknown devices, if you can't see them now anymore, try again to unlock your bl.

    flashed the azuzu kernel downgrade ftf with flashtool
    - OK no problem
    disconnected usb cable, pressed power button until phone vibrates shortly and immidiatly connected the usb cable again
    - Ok no problem
    started the batch file for unlocking bootloader, cause it says press any button before it starts
    - started? you mean "start"? how do you start the file meflash.dll?

    I think something is missing?
