Greetings.

run attached tool, press "restore"
required flash mode drivers and unlocked bootloader ;)

support both 7227,8250 phones.


edit:
updated s1 tool with flashing capability.
will flash standard decrypted semc *.sin_file_set, "flashtool" *.ftf file set
understand scripts inside packages ( *.ta extension )
benefits over flashtool : small, fast, no need any "jaba"

the only requirements are flash mode USB drivers and unlocked bootloader!

stock kernel for unlocked bootloader from DoomLord.

EDIT :
When I try to use this tool to restore bootloader, I'm unable to boot on my phone.

Then I try to reflash stock firmware again with Flashtool. Now, it able to boot on.

Maybe this tool cannot be used on Stock Kernel provided by DoomLord.

no, you can't boot with ANY custom kernel on locked bootloader.

Is there any method which tell you exactly about bootloader either it's locked or unlocked? I am asking this question because I run @9Lucas5 method and than I restored Thejap Rom. After the restore, I got Xperia bootanimation (first) SE animation and finally Thejap boot animation. Yesterday, I install Thejap new version and now SE bootanimation is disappeared and I have Xperia and Thjap BA. Phone with excellent deep sleep (85%) and great battery life. (which is reported by many unlocked BL user very bad) Now if I want to go back by this method what will happended when I don't know my phone's BL is LOCKED or UNLOCKED.

VERY SIMPLE WAY TO FIND IF U HAVE LOCKED/UNLOCKED BOOTLOADER

DOWNLOAD THE S1TOOL pc application from 1st post

do the following:

x10-bootloder-info.jpg


  1. click on Identify
  2. Connect device in FLASH MODE
  3. check output
  4. check the marked strings
    • if the strings begin with "r" (lower case) then bootloader is UNLOCKED
    • if the strings begin with "R" (upper case) then bootloader is LOCKED

Curious... Are you the same the_laser that makes SEtool and LGtool? If so, you are certainly awesome

Edit.
Wow, my sig is waaaaaaaay out of date!

Also would the same rule apply when identifying in setool? r for unlocked, R for locked? Got an x10 that identifies loader as DEAD, just wondering if there's any hope for it or is that the funniest most accurate piece of code ever?

    Yeah because for some people like me, bootloader unlock lost my wonderful three day battery life, :D

    Thanks laser!
