Default [unlock bootloader] [Relock bootloader] [Xperia e ss] [other Xperia] [noob friendly]

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.c...9eae2b99647ffc .
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...ldescription=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_d8...UTA/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_d8...it?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.

Sign [Q] Unlocking bootloader with a Mac...

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!

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,.

here you go for adb for mac - http://forum.xda-developers.com/show....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
