I recommend using Xperia Companion Software. It will fix your issue.

@Nomad

That's not going to work because he has unlocked the bootloader

@Ankit20

I doubt that it will be covered by warranty as unlocking the bootloader voids the warranty.

@uliwooly:

Xperia Companion Software will flash the whole System Software and help him leaving the boot loop.

It will not relock the bootloader.

Nope, it won't work, as long as the bootloader remain unlocked, XC won't work, it won't recognize the phone.

Got an unlocked X and XZ, Xperia Companion Software works for both unlocked devices.

@Nomad

it won't work if the bootloader its unlocked, if the phones are unlocked from a carrier network then XC will work.

@Ankit20

I guess your tried recovery mode?

Entering recovery mode by pressing the Power button+Volume up button and hold, till you get a screen which is the recovery screen. Now, you should be able to see options like Wipe Cache, and Factory reset. In order to get out of this bootloop situation, first tap on Clear Cache.
Then tap on Factory reset.

THIS METHOD WILL DELETE ALL USER DATA.

Otherwise, give Xperia Companion a try (yes it works with unlocked bootloader, i just used it last week to fix my X which has a unlocked bootloader).

There isn't a recovery mode on Xperia, nor will Xperia Companion recognise your device after bootloader unlock, as was pointed out earlier in thread.

I had followed the official instructions by Sony to unlock my Xperia E (c1504) bootloader and it was successfully done

but when i booted it , it was stuck in boot loop [ i.e Sony logo >> Xperia logo >> animation (6-9 sec)>> screen off >> ......repeat] I also tried of after removing the battery ,but again stuck in boot-loop .

and the flash tool and Xperia Companion is not detecting my device nor in fast boot nor in reboot.

My Sony Xperia E (c1504) is not in the supported devices list for flash tool at https://developer.sonymobile.com/open-devices/flash-tool/supported_phones/

If there is a recovery mode please let me know how to get there.

I don't know why, but the Companion Software works well for my devices with unlocked bootloader. I have to say i didn't used it when i had boot loop problems. Last week after flashing a selfbuilded ROM which had some issues, the Display was non responsive. Flashing a working image didn't solve the Problem. So i had fixed that problem with Xperia Companion. Did you try both, connecting in fastboot mode and flashmode? If there is no native recovery mode, you can flash a twrp image (i use it on both phones).

I'm sorry, i have to correct myself. I just bootet my Windows to test it. I fixed my problem with the Flashtool not with the Xperia Companion Software. The Companion Software doesn't recognize my devices. I confused this two programms.

@Nomad

Again, XC WON"T work with an unlocked bootloader, if you unloocked the bootloader BUT you re-locked the bootloader then you can use XC. Also, there is NO recovery.
