Xperia SP boot loop into flash mode

Question

I have an Xperia SP, and it's stuck in a boot loop after some faulty manipulation. I only see Sony's logo, and plugging the phone to my laptop sets it to flash mode automatically for around 20 seconds, before restarting to connect again straight into flash mode.



How can I fix my phone?

Answer

To solve this boot loop issue, start by flashing this kernel via FlashTool, switching your phone into fastboot mode. The best is to follow the original guide I guess.



Then, you can follow this tutorial to install a custom .zip file ROM again, allowing your phone to boot again. You might need to upload the .zip file directly onto your SD card.



I hope this helps.
