[Q] Xperia U not turning on please help! Flashing went wrong!!

I wanted to unlock my bootloader and install a custom rom but my windows won't recognise the fastboot mode so I started up with linux
I saw tutorials of recoveryX.exe and flashtool which only works for windows so I was searching for a manual way so that I could do it in the terminal ..
so I found some tutorial online which told me to flash some file something like
fastboot flash boot xyz.inf I don't remember the extension perfectly but it wasn't a zip or an img ..
and after that my phone turned off, I can still go for fastboot mode but I don't see anything on the screen please help me
I do not have windows so I cannot use flashtool or recoveryX.exe

Congrats for the brick.
Can you still get into fastboot/flash mode?
I've yet to hear about someone who used rexoveryx and it worked, forget all about it.
There is flashtool for linux, you can use it.
BTW, the only files you flash with fastboot, are with img, elf or sin extention.

I have downloaded flash tool for linux but I cannot get it work .. I cannot get it to install or anything
isn't there a way to do all this manually through Terminal Fastboot commands?
That's the only thing that I can manage to work.
Edit : I have flashed the boot.img file from the downloaded ROM I did it this way (fastboot flash boot boot.img)
and now fortunately the phone starts and also now can be charged but the OS doesn't start .. I think this can be because I haven't flashed the OS but only the boot img?
what can I do now?
P.S : I cannot use the Flashtool or RecoveryX :/ so if there's a way to do it via fastboot or something it will really be appreciated

Make sure you rename the cwm recovery to "recovery.img" without the quotes. Put the recovery.img into the android SDK platform tools folder.
Use command prompt and type -
cd \Android\android-sdk\platform-tools
fastboot flash recovery recovery.img
If recovery is successfully installed you'll receive a notification that say's -
wrote recovery partition

Use either cwm 6.0.3.1 touch or the non-touch cwm from here- http://forum.xda-developers.com/showthread.php?t=2313794
Just click on the recovery that you want and it will automatically download the recovery.

You have to install the fastboot drivers twice to get it to work right.
Put the recovery.img on the sdcard of the phone and try the Flashify (root) App from the play store and it should install the recovery just fine.

Just try the Flashify app first... You don't need to use fastboot with Flashify.

Just root it easily with Cydia Impactor...
Download the Cydia Impactor tool to your pc from the Cydia Impactor website. Extract the zip to a new folder on your desktop. Connect your L9 to your PC with USB debugging enabled and open the extracted cydia folder and click on and run the Impactor.exe, when the Impactor tool opens just click on the start button. Cydia will root your phone in like 5 to 10 seconds.
Download SuperSU from the play store, install and done.

@DARKSKIES
I just want to make sure that you successfully unlocked the bootloader... When you issued the "adb reboot oem unlock" command you were taken to a confirmation screen to unlock the bootloader and you had to use the volume key to confirm unlock?
Just want to be sure so you don't have any security errors or a brick.
Hi could somebody help me? Thanks!

Awesome... I'm glad I was able to help you.
Before you do anything else, make sure you perform a nandroid backup of your device through cwm now and make the backup to the SD card and not on the device so it doesn't take up unnecessary space on the internal memory.
Before you flash a custom ROM make sure you read through the OP's ROM flashing instructions and prerequisite to make sure it's compatible with your device and cwm version.
Enjoy the new possibilities of your phone and happy ROM flashing!

That's probably b'coz it still isn't flashed.
Install MiPc suit and connect once with USB debugging on so that all the drivers do get installed correctly then
When using adb first type adb devices and look for your device to be sure that the device is connected correctly.
Which Twrp are you trying to flash?
