I can't Connect My Bricked Phone..

Hello Xda... I Can't Connect My bricked Phone to Pc. When i put it and turn it on flash mode it tells that failed to install the device drivers. Seus , PC Companion , Flashtool Can't Recognize it. can anyone help me? Thanks In advance.

First of all how you broke it? Second before you can proceed with seus or any other tool you need to install all drivers for your phone.....

How far does your phone boot-up?
Do you still see something on your screen?
Does the LED still light up (when connected to the charger/USB)?
If you haven't killed the boot-loader you should be able to recover the device with Flashtool ... if the boot-loader is dead I think there's no easy way to resurrect it.
Of course the unsolved question is if it would need a intact kernel as well AND if custom kernels actually support "Flash mode".

Finally I did it! Big Thanks to you. I Installed the drivers and it recognized. big thanks

Well, that's exactly from where Vlackrs and I already recovered our phones after a bad flash ("stuck at the Sony Ericsson logo").
Start Flashtool and select "Check drivers".
If it turns out as "OK" on all three checks it seems you have the drivers installed already.
If not ... try to install Gordon's Gate (should be included with Flashtool and called "ggsetup.exe").
Follow the instructions I wrote up here to restore the device.
Note that I did NOT use Flashtool 0.5 as 0.5.0.0, 0.5.0.1 and 0.5.0.2 failed to recognize the device (and yes, I replaced the "E15.properties" with the files posted in the Flashtool thread in the Development section) - Flashtool 0.2.9.1 did the trick for us.

Please help !

This method will install the original software on your X8!
If you have Sony PC Companion 2.1 on your PC, then uninstall it, and download and install Sony PC Companion 2.1, again! If not, then PC Companion might not recognize your phone. After installing do the following:
- Turn off the phone, and unplug it from the PC
- Turn on Sony PC Companion on your PC
- In PC Companion, enter the Support Zone tab
- Go to Update Phone Software
A window will pop out, saying that it cannot find your phone
- Click on Fix Phone
- Click on Continue
A window will pop out, saying that you will lose all your data
- TICK the BOX
- Click on continue
An update process will began.
Wait for it to show a window with all the SONY mobile phones
- Find your phone (X8)
- Click on the phone.
Now all you have to do is follow the on-screen instructions. It will tell you to hold the back button and plug your turned-off X8 to the PC, then it will erase everything, and download the original 2.1 ROM to your X8.

yes

It doesn't work it says that Pc companion was not able to connect to the device. I tried many things bu pc companion just cant connect my phone and windows keep saying that error that i am plugging unknown device which is a bull**** the day before it was working fine...
For all people who didnt understand iCANT ENTER IN FLASH MODE I MEAN I CAN BUT ITS NOT RECOGNISED so i cant update my software.

also
also flash tool in the console says that it cant determine what deviec i am plugging into and cant display what is busybox version or anything like i am putting an unknown device...

Hey there, my phone isn't bricked...but I think I have too much data (possibly conflicting roms installed at the same time??) and I wish to reset my phone to its original status... I wish to re-install a ROM on it, but I want to start fresh again by removing the rooting programs or what have you..
Would following these steps put it all back to its original setting, also meaning that I could completely wipe the SD clean?
If so, would this mean I would have to re-root my X8? Not that it would be a problem but I would just like to know if it would be needed!
Thanks!

if you want to restore the stock rom (original androdi on xperia x8) with pc Comapnion than you dont need to root it again. But if you want to change it to custom rom and you have done full wipe i think you should root it again (rooting is done so taht you can change the busybox version of the phone and upload xrecovery if you have those you don't need to root)

Why don't you download the store Rom annd use Flashtool to flash it? Then you may be able to upgrade to latest revision with PCC.

Yeah, I lost you somewhere... If after taking out the battery, you CAN NOT enter xrecovery or CWM, then, you either can try THIS THREAD <--- go on, click on it!, or, you have to do what I had to do a couple of times, which is to restore your X8 to its original state, and to do that with Sony PC Companion, you first have to UNINSTALL your current PC Companion!!! THEN, restart your PC, and install a clean version of Sony PC Companion 2.1!
IT DOESN'T MATTER IF YOU HAVE THE LATEST VERSION of PC Companion, YOU STILL HAVE TO UNINSTALL IT, AND INSTALL IT AGAIN!!! IF YOU DON'T, THERE's a 99% CHANCE THAT PC COMPANION WILL NOT RECOGNIZE YOUR PHONE!!! ...I don't know why, but it's probably some marketing trick, since I once used this method 3 times in a row, then the fourth time PC Companion didn't recognize my X8. This happened on both, the old PC Companion, and the current Sony version 2.1. I tested them both on purpose, to eliminate the possibility that I damaged my X8's hardware somehow, during a high speed impact collision with the bedroom wall...
Once you reinstall Sony PC Companion 2.1, go back to my first post to your problem, and follow it step-by-step.
AND yes, if you want to install custom ROM's again, then you will have to ROOT your phone again, and UNLOCK the BOOTLOADER, etc...
BUT, if it's a soft-brick, then you might be able to redeem yourself

how about kernel?

>> how about kernel? for example your phone allready back to 2.1 rom and you are using custom kernel before i done this update? like kernel aA-11? is it possible to turn on phone even if im using custom kernel? please give me steps how to bring it back, because im currenty using mini cm7 / kernel aA-11, and i want to bring back my xperia x8 to original rom and kernel

Try downloading the stock rom and a diff version of flashtool. I can't remembet which version is most recommended (try searchibg xda - i read it here). install drivers in flashtool's driver folder (gordon's gate) then try again. Almost the same thing happened to me. PCC won't recognize my phone so I couldn't install the drivers.

The best way, if u still can't get on your phone , is take it to the SE Customer care. And don't tell a word about rooting or anything. Just ask them to repair the phone, saying that one morning, the SE logo kept on popping up.

U said it does not connect, have you tried connecting it normaly with p.c with debugging on letting the drivers get installed first..
1. Install the PC Companion from SE.
2. Connect Phone to PC also PC Compannion asked for, let Windows find all Drivers.
3. Switch USB-Debugging on, one or two more Drivers will be found.
4. Start SuperOneClick, click on "root". Wait ~10 Seconds to finish.
5. Reboot.

okay...
if you're still confuse, downgrade your phone!
its last option
downgrade into 2.1 - download this file from files crop X8 E15i 2.1.1.C.0.0._un.ftf
root your phone by flash tool..
then install xrecovery by clicking cross icon on flashtool
OR
download this file (password=cintaindonesia) and extract in your SDcard
after that copy paste three files(busybox, chargemon, xrecovery.tar) in system\bin
and you will get xrecovery
after that
unlock bootloader using flashtool OR s1tool
Flash the latest kernel
backup
factory reset, wipe data, etc
Flash ROM
done!

Have u installed gordon gate drivers?
First connect phone then hold press back button untill green light show. Then check if windows recognized it.
Then remove battery.
Go to flash tool select the ftf u want to flash then wait until the dialog appear. Then connect phone (if u unplug before) insert battery hold press back till green light show, now it should be flash

sometimes its happen cz :
- drivers not installed correctly (x8 drivers and gordon)
- make sure your unlock BL process work successfully
- check all your hardware connection (cable, usb, etc)
don't forget to have > 60% battery

have you install the driver from /driver folder on the flashtool installed folder??
and dont forget to check the X8 ADB driver and fastboot / flashboot whatever LOL
just check that 2 thing and you shouldnt get any problem

Hey install the gorden gates driver provided with flastool and try again.....

First unlocked the bootloader(BLU button, got the IMEI, used the sony form (http://unlockbootloader.sonymobile.com/instructions))
Then I downloaded the stock sony xperia z ftf image, placed it in Flashtool's firmware folder, then flashed it (flash device > flash mode).
Now my phone's working again.

If you still can enter custom recovery, you only need flash rom and (with) suitable kernel.
If not, you need Flashtool.
- make sure you have the newest version of flashtool and driver
- connect your phone to pc.
- when computer show error about usb not recognized, go to computer management - device manager. Find something in universal serial bus controller list that have yellow triangle and exclamation mark. right click and remove it
- disconnect your phone then reboot your pc
- install flashtool and driver, reboot pc again
- connect your phone to pc. Now, it should detect your phone.
- do flashing procedure
