Chosen Solution

My Sony Xperia S SGPT121 is stuck on the blue flame. When I power it on it shows the Sony Screen, then the Xperia Screen, than the blue flame running from left to right… and this continues for hours. I can force a shut-down by pressing the power button for 10 seconds. I tried the factory reset (Volume-up + Power-on, release Power-on at Sony Screen) but it is not going to the setup screen. It has no effect at all - simply going from Sony Screen to Xperia Screen to blue flame….

I do have the same problem

I have the same issue

I found no solution and finally bought a tablet with broken screen on ebay and combined the electronics from the tablet with the broken screen with the screen from my tablet.
