How to relock bootloader?(Solved)

[eddie24902005]

I tried flashtool BLU function, then I could not find XA1 ultra on the list, I tried XA1, the relock process finished and the phone cannot start. It says failing to verify. I am relocking because my phone starting to have ghost touch and needs to be returned for warranty service. Thanks so much!

Update: I use the Xperia companion to restore. The bootloader lock itself back.
