Before you proceed with the steps to unlock the Bootloader of your device, make sure you check if you are safe to do that or not.
You may brick your device permanently if you do not perform the check.
Prerequisites
Before you proceed with any hacking activity on your phone, it is always better to have a backup of your important data.
- Backup all applications using ASTRO File Manager which also lets you store the backed up file on its servers.
- Backup all contacts to SD card.
- Most of the SMS applications let you back up SMS to your SD card. You can use Go SMS or Handcent which are the most famous ones
Disclaimer: BlogoTech is not responsible for any damage that might be caused to your device during this process though the possibility of any damage is negligible. Try this at your own risk.
Check If You Are Safe to Unlock the Bootloader
- Download s1tool
- Run the program and click on the Identify button. You will get the instructions to turn off your phone, press and hold the back button and connect it to the Computer using USB Cable.
- If it says ”SEMC SIMLOCK CERTIFICATE” or “SETOOL2 SIMLOCK SERTIFICATE” you can continue with unlocking but if it says ”NOT RECOGNIZED SIMLOCK CERTIFICATE”, STOP RIGHT HERE.

Hi,
When i click plugin nothing appears. Plus my i have put my device in debug mode, but the program says debug is off.
Can you help ?
Thanks
Do you have USB Drivers installed properly?
It may be because you do not have root privileges, see the FAQ on the Flashtool website.
Just press the big lock icon in Flashtool, that will do it. Leave your phone plugged in, it’ll reboot, and then the plugin menu should be availalbe.
Hi,
I managed to do it, i had to keep switching phone on and off because when phone was off it wouldn’t recognise it as debug on.
I managed to do this, what does it do? I tried this thinking it may unlock my mobile phone so i can use it with other networks.
Thanks!
Hello
I have already got root and have a custom gingerbread rom installed on xperia x10 mini. Do I need to roll back to stock rom and proceed with unlocking process ? Or can I do it on custom rom itself ?
Thank you!
I guess you would have unlocked the bootloader before installing custom ROM!
No i dont think i unlocked the bootloader before installing it. The ROM runs on the stock kernel itself. Is there any way to check if its locked or unlocked ?
You can see that in the flashtool!
Hi!
I read the tutorial and I want to correct you in some points.
Unlocking the bootloader doesn’t allow you to flash Custom Rom’s. You can do it even without unlocking it. You just need Root privileges, and a recovery (CWM).
About the unlocking, please check your date under the battery on the phone.
If it is below 11W29, then don’t proceed doing this. It will hardbrick your phone(Trust me, I did that), then you need to send it to SE Repair, and act innocent.
