Sorry, can't find thread for xperia e1 dual. I would be thankful, for the help. I used flashtool for unlocking bootloader and then after 'get unlock key', it took to the sony official page
http://developer.sonymobile.com/unlockbootloader/

but xperia e1 dual was not listed under select your device. It also say, If your device is not in the list, it’s not possible to unlock the boot loader.

In my device I entered *#*#7378423#*#* and Bootloader unlock allowed says Yes.

thanks for this. It worked, but bootloop after. No worries though, I flashed zeus kernel and tried custom roms and it's working fine.

Thank you for this guide.

It worked but I ended in a bootloop after the unlock.

I flashed CWM recovery (the unlock was successful) and did a wipe data/factory reset ... and then my xperia was back to life again.

    this guide is for anyone having trouble unlockin bootloader.
    note: unlocking bootloader voids your warranty but hey you can relock your bootloader and your phone is under warranty once again
    note : after unlocking bootloader of Xperia e c1504/1505 c1504 goes into bootloop and in some cases c1505 also faces bootloop.so backup all your data.
    1)- open the dialler
    and enter *#*#7378423#*#* to access
    the service menu. In your device, tap Service info >
    Configuration > Rooting Status . If
    Bootloader unlock allowed says Yes,
    then you can continue unlocking your phone..
    if its no then please stop and don't try the next steps.
    2)- go to developer options in your phone and enable usb debugging and in security options tick on allow installation of non market apps.
    3)- download http://adbdriver.com/upload/AdbDriverInstaller.exe and install adb drivers installer on pc,open it and connect your phone to pc and install the adb drivers.
    4)- download flashtool http://androxyde.github.io/index.html?1350585408000 and install on pc.
    5)-open flashtool folder>flash tool drivers>flash tool drivers and then select fastboot drivers and flashmode drivers and install them.
    6)- download http://www.androidfilehost.com/?fid=9390169635556426292 and extract it adb_fastboot_and_other_tools.zip and place in on your desktop/any other drive.
    7)- go here http://unlockbootloader.sonymobile.com/node/add/ubs-request?token=eff07a162ac0f98cb19eae2b99647ffc .
    fill your details and then check your email inbox for bootloader key.
    8)- Turn off your device.On your device, hold the volume up at the same time as
    you connect the device to the computer
    with a USB-cable. (volume up is the fastboot button)
    9)- on your pc start>type cmd and open a command prompt and navigate to adb_fastboot_and_other_tools folder . if you don't know how to use a command prompt then. see this http://m.youtube.com/watch?client=mv-google&gl=IN&hl=en-GB&v=foYsmpDrYjY&fulldescription=1
    10)- Enter 'fastboot.exe -i 0x0fce getvar' without the single qoutes in the command prompt and verify that you get a
    response back (for example "0.3"). This
    means your device is connected
    properly.
    11)- enter 'fastboot.exe -i 0x0fce oem unlock
    0xKEY' ,without single quotes where KEY is the unlock boot
    loader key you got in step 7 .. after doing this you will get reply as done on pc and your bootloader will be unlocked.
    using the above instructions you can unlock other Xperia also which has bootloader unlock allowes to be yes.backup your data before unlocking.only the fastboot buttons will vary. you can get it here -
    http://unlockbootloader.sonymobile.com/fastboot-buttons

    steps precisely for Xperia e c1504/1505 facing bootloop after unlocking bootloader -
    1)- download stock ftf file https://docs.google.com/file/d/0B_d8uWGbkaetNS13Mmk4WEhrUTA/edit?pli=1 and copy it in flashtool>firmwares.
    2)open flashtool click thunder icon select flash mode and select the stock ftf.
    3)- connect Xperia e as shown in step 8 but with. holding volume down button instead of volume up. you will get a green led
    4)- original firmware will get flashed and initial startup will take about 5 minutes. so be patient.
    steps for relocking Xperia e bootloader
    1)- download https://docs.google.com/file/d/0B_d8uWGbkaetYmh2V0l5Q0dFQW8/edit?usp=sharing
    2)- flash it in same way as you flashed the original firmware..
    note)- after relocking bootloaDer//on a locked bootloader if you face bootloop then use Sony update engine (download from official website) to flash original firmware.
    hope my thread helps.

    The latest Flashtool (v0.9.11.0) has "BLU" menu to make Lock/Unlock bootloader more easier.

    the simple step :

    1. Set up Flashtool to be ready for your device.
    2. Refer to the SONY link provided in OP, and get your bootloader key
    3. Connect your phone to Flashtool.
    4. Click the "BLU" and follow the step.

    hope that work for Xperia E,.

    thanks for the post. ive been reading hundreds of pages here in preparation to root my phone (XPERIA E/c1504.) i know that unlocking the bootloader is step one, so your guide is pretty helpful, but i'm on a mac! does this change any part of the process?


    3)- download ADBDRIVER and install adb drivers installer on pc,open it and connect your phone to pc and install the adb drivers.
    4)- download flashtool ANDROXYDE and install on pc.

    i know i can get androxyde for mac, but is there a mac version of the adbdriver program?

    7)- go here SONYMOBILE .
    fill your details and then check your email inbox for bootloader key.


    if you contact sony for the bootloader key, unlock, then lock back if you have to return it to them for warranty issues, etc., won't they know since you had to get the key from them?

    thanks for your help! im a definite beginner but learning a lot from this site!

    here you go for adb for mac - http://xdaforums.com/showthread.php?t=1917237

    okay your next question is quite good. first when I unlocked my bootloader and faced bootloop. I got my phone a Sony service centre. the guy there took my phone on warranty and tried to reinstall software through sus (works only on locked bootloader). then when he was unsuccessful he told me software modified and I got my phone back
    so I don't think you will have any issue with warranty.
    you can get any Xperia phone's bootloader key in your inbox just by knowing its imei.
    so no issues at all.
    P.S : rooting can also be done on a locked Xperia e

    i couldn't find anything useful in ur post sorry to say that but as i said after unlocking the bootloader the factory data formatted and usb debugging was disabled due to which flashtool is not able to read my phone during flashing and hence cannot flash the stock ftf file. now what should i do
    Click to expand...
    Click to collapse

    Dude to flash stock ftf you need not enable usb debugging.
    Power off, click flash, connect phone in flashmode..

    Have u flashed your phone before?
