I can also confirm that if you re-unlock your bootloader using flashtool, it won't wipe anything. And you can make a twrp backup of your stock kernel and TA partition, so you can relock it on the go

Hi I tried to unlock my phone and I had the Sony code and every thing is done using flashtool .
My problem some ROMs don't work the only ROM worked for me is the evo9 ....
In the dailer I entered the code to see if I'm locked and it fails to open configuration nothing shows ??? Is something wrong???

nope, you had to backup them the first time.
Now you can just relock
Just a quick question.
What are the risk of unlocking the bootloader from flashtool? What is the success rate?

No risk. It still based on the official unlock method

You can't.
Though, you can backup TA (before first unlock)
This way you'll be able to roll back at anytime

Yes, i unlock my bootloader but i relock again with my TA Partition backup pictures in low light conditions are very bad with Unlocked BL

I unlock my bootloader, but with the TA Partition backup i relock again. Now can i unlock bootloader again ?Yes, i unlock my bootloader but i relock again with my TA Partition backup
In the first time I use original Sony method, now I need to use flash tools to unlock right ?
Flashtool unlock and sony official unlock are the same thing

So, if i want to unlock again and use sony original method it will work right?
Yes.So, if i want to unlock again and use sony original method it will work right?
The unlock code is still the same of the first time.
Besides, if you are switching so often between locked and unlocked status, I would suggest to backup even unlocked TA, so that you'll just need to flash it to unlock without /data wipe

Install PC companion (PCC) or Sony update services (SUS) on your PC and simply update it.
Or find 4.4.4 latest .ftf and flash via flashtool.
Every thing you will find on XDA & Sony support site.
SUS has been discontinued afaik

Hello! I read somewhere that if my phone's manufacture date is 11W29 or PAST 11W29 I should not attempt to unlock the bootloader because the phone will hard brick, is it true? My Xperia Z1 says "13W39" but the bootloader can be unlocked as I have checked multiple times, please help
