i meant fastboot mode ^^

(1) Use PC Companion and do a repair.
(2) Download the relevant firmware file and use Flashtool to flash.

I will try this right now and I will report if it worked or not ^^

You need to provide a lot more information.
If you follow the OP I gave you in the earlier post, it works. Why are you using Fastboot??? You should be using Flashmode in Flashtool.
You need to ensure you have the correct PC drivers.
Again, assuming you have read and followed the suggested linked method, provide more info about your phone state.

And which method did not work? Us your bootloader unlocked?

How can I see if it is unlocked ^^ sorry im a noob+

Unlocking is an intentional act. If you have not done it before, then it's still locked.

oh okay. Is this really relevant? Because.. I dont know but I think, that the warranty void is damaged by doing so

It's relevant because if your bootloader is unlocked, then you need to use Sony Flash Tool to flash stock firmware.
So which method failed for you? And which step failed and what's the error? You need to give us more info so that we can help you.

Hello.
I'm having problems with my XPERIA x10i phone. This morning I was changing the case with new one. The full case, not just the cover. And then, my software was stuck in a loop at the Sony Ericsson logo. I tried installing the software with PC Companion, Update Service, FlashTool and none of them seems to work! They all stuck at the same place!
What could be the problem???
Thanks in advance!

I thought of that and I've reassembled looking at this video youtube com /watch?v=JVBTCgAzkY4
I did everything like in the video. If I didn't put anything correctly, the phone wouldn't start... :/
Any specific ideas to look for?
Thanks a lot!
If you had the battery disconnected during your work changing the case (and you definitely should), then put your phone to charge in wall plug for at least 15 minutes (or even more) and then try to turn it on...

I've tried and after 5 min. the phone start itself and starts the loop.
I've installed older version of FlashTool and read this line:
Loader version : R4A024 / Bootloader status : UNROOTABLE

After flashing I'm facing the problem. Now, the phone just shows the lights on the screen, no SE logo...
The flashing finishes perfectly with no errors and the phone is connecting again in flash mode with the green LED in the upper part. But, when I try to turn on the phone, just the blank screen is lighted, no logo...
Is my phone dead?
I think so
Sorry I can't help you.
Edit. Have you tried another firmware/re download the file? Just in case. Good luck bro.

Yes I tried. Do you have any working firmware (tried)?
In the service center, the guy told me something about wiring the phone under the battery. That was the last hope for the phone...

What is your exact model? Because you stated you were running Gingerbread 2.3.3 on it... Was that the original firmware it came with? I think you need to be in this forum, for the 'big' X10, and not the X10 Mini (e10i).

[Guide] *Updated* Better explanation to unlock you bootloader.

Tip: if the flashtool not regonize your phone, use pc companion to install the SEMC Usb Driver
to let flashtool regonizing your phone.
howto do: use pc companion, do what it says,
if it says: you have already the new update, press recover, he install the SEMC Usb Driver,
then press cancel.
Now you have the Semc Usb Driver installed on your Pc/Laptop.
Updated with the new kernel from DooMlord.
read this carefully:
http://forum.xda-developers.com/showthread.php?t=1254087
i do this:
1: Please make sure you have enabled usb-debugging in your current rom before starting with this!!
2: flash the azuzu kernel downgrade ftf with flashtool
then do this and download this
http://forum.xda-developers.com/showthread.php?t=1256430
if it no respond just wait, i must have his superuser action regonize
then do this:
3: after unlocking is finish you have to flash azuzu kernel upgrade
4: 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)
power off phone and flash X10_2.3.3_DooMKernel-v06-FS-BootManager-v1.4.ftf
with flashtool
now reboot your phone and go to XRecovery and install the zipfile: x10_gb_DooMKernel-v05a-FS_wifi modules
power on phone again and if everything is right, read the line under that one
WOOOHOOO!!! Here you are with unlocked bootloader, custom kernel directly loaded AND without reflashing any rom, means you have kept your current installation
Doom his files:
Flash this with flashtool: http://www.multiupload.com/ISV5FMZHJ0
install this with xrecovery: http://www.multiupload.com/XMB0OO8PWH
i do it like this and it works !
Important !! If you are using the Unlocking Bootloader tool, just wait, do nothing,
He must get his acces to superuser, look at the letters/numbers in the tool
[*] >> run ADB in tools as administrator of x10 bootloader dont work, after that it works !
press hard but safely the Thanks button !!
succes !!!
p.s. i help a friend yeeyon1990 and myself and maybe more.
Its working !!
Thanks to:

It is not an easier method, using flashtool 0.4.2.0 is the currently the easiest method.

Mine were all black screen but when I plugged into the PC, I would get it recognized as SEC-S5.... (can't recall the exact driver it was looking for). So mine was semi recognized. Now, if you are telling me that your PC does not recognize it at all, I am not sure what to tell you.
