[Sony Xperia M4 Aqua] ITRCSS:
Can´t unlock Bootloader

I go to sony page and choose M2 and get the code.

Then I do all this steps:

"1.: Go to the folder where Flashtool is installed. Usually C:/Flashtool

2.: Open the folder named "Custom"

3.: Open the folder named "Mydevices" (if it exists, in my case Flashtool version 0.9.18.4) (You may create if it doesnot)

3b.: In the newer Flashtool, you need to put the folder in "C:\Users\<username>\.flashTool\registeredDevi ces" in step 3.

That is, if you've picked the default for your flashtool home folder or you can choose manually.

4.: Create A New Folder and Rename the folder with your device code. Refer to Obs2 how to find your device code

5.: Open the folder created previously

6.: Create a new text file and rename it as ulcode

7.: Paste your unlock code and save it in the text file

8.: Open Flashtools and try the BLU option again.

Obs 1: the step #3 I think it depends on your Flashtool version, because it wasn't mentioned at the solution

Obs 2: at the step #4 is mentioned your device code. your device code is showed in the log when you click the button BLU, at the "Current device", after your device model.

Search a line like:

09/045/2015 23:45:08 - INFO - Current device : C2104 - AB100C2DE3 - 1272-4136_R5B - 1269-5420_15.3.A.1.17 - WORLD-a_15.3.A.1.17

in this case, the device code is AB100C2DE3 and this should be the new folder name (step 4)"

And the Fashtool always say this:
