Re: How to relock bootloader?

I tried to relock my xperia XA by using xperia companion 


To do so-

1. connect your device in flash mode then launch flash tool

2. then click on BLU(boot loader unlock) after process again click BLU and then click relock

3. Your device may not boot aftrer showing sony logo for a few seconds 

4. Go to xperia companion > software repair > check the box "my device cannot be detected">click next>select android 

5. And it should start repair after a few minutes  

6. After process disconnect your device and reboot it, it will take longer than normal reboot
