[Xperia SP Q&A, Help & Troubleshooting] Spjosc:
Hello Everybody

My Phone: C5303 - YT91094GAN - 1272-7170_R3B - 1269-3538_12.1.A.1.205 - ORANGE-LTE_12.1.A.1.205

What Happend? About a year ago I wanted to get my whatsapp chat history from my phone so I had to root it. I used KingoRoot program in my phone to root, get files I needed but after I unrooted my phone with that program it does not work.

Actual situation

If I turn my phone up this shows

I can than turn it off by the OFF button on the back and I also can access some flashmode( I don't know exactly how is it called) With pressing vol down and power(green LED) also I can press vol UP and power to see blue led).

After 13 hours the repair logo is still on the screen.

So I tried some flashtool and here are the results:

flashtool version 0.9.18.6
