[Xperia Play Q&A, Help & Troubleshooting] ThirtyOne34:
Hello dear readers and great XDA members,

Last summer I unlocked the bootloader of my Xperia Play R800i with the testpoint method. Everything worked fine: I installed CWM and loaded a FreeXperia version of CyanogenMod 9.1.

A couple of days ago, I wanted to finally update my ROM to a newer version since there had been so many releases since last summer. I loaded the new ROM and everything worked fine. However, some of the problems I hoped would've been solved by the update, weren't solved at all, especially the video capturing and panorama pictures. So I decided it maybe would be better to flash a new kernel.

I searched for a kernel, but couldn't find anything I liked. Then, I can't remember where, someone posted the "boot.img" files included in the FreeXperia CM9 ROM zip packages were kernel releases. So I decided to use flashtool and flash the boot.img as a new kernel.

This obviously didn't work and I tried some others. By the way: I couldn't boot into ClockWorkMod anymore since I tried to flash a new kernel. Only fastboot and flashmode would work.

I couldn't remember which kernel I used last summer, so I wandered the internet and eventually found that an X10 kernel was included in Flashtool. I though I remembered something about X10 from last summer, so I decided to stupidly flash that kernel to my Xperia Play.

After this flash completed, my phone doesn't respond to anything anymore. Following a list of things I tried (everytime after I tried something, I removed the USB cable and the battery to make sure the Xperia Play was turned off):

- When I press and hold the power button, nothing happens, not even the small vibrate always felt when the phone starts.

- Getting into fastboot mode doesn't work anymore (I tried with holding the search button and connecting USB, as well as some other buttons, nothing worked.)

- Getting into flashmode doesn't work either.

- No matter what I do, the phone won't give me a sign it's still alive. (no LED, no vibrate, no screen, nothing.)

- I tried the Sony Update Service, but that obviously doesn't recognize the phone

- Flashtool doesn't recognize the phone either.

- ADB doesn't recognize the phone of course.

- s1tool (the tool I used for the TestPoint bootloader unlock) recognizes I plug something in, but then gives an error it can't get access to it.

- I charged the battery overnight and tried all of the above again... still nothing works...

- When I plug in the phone to the PC, my PC recognizes something plugged in, but with the name QHSUSB_DLOAD in Device Manager.

(by the way: I am using Windows 8 Pro x64)

Is this phone completely dead or is there any way it can be saved? I was planning on keeping this phone at least until the end of 2013 or begin of 2014 before upgrading... An immediate upgrade is not in my budget and for now I have returned to my Nokia 5530 on Symbian, but that's nothing compared to Android :'(

Thank you very much in advance... I really hope someone can save my poor phone. I know I have been stupid, but I think I somehow panicked when I couldn't get the phone back into CWM and stupidly flashed the X10... Stupid stupid me.
