[XPERIA X10 Q&A, Help & Troubleshooting] vlambrecht:
Hello, this is my first post on this board, and this is sort of my debut question.

Firstly, I would like to say that I have had lots of programming experience, as well as microcontrollers and other hardware, so feel free to throw any jargon or acronyms (relative ofc :)))

I bought a Sony Xperia x10a from Kijiji. When I inspected the item (in person), it worked flawlessly, albeit a little slowly.

Taking it home, I turned the phone off, and that's where the problem happened.

I turned it off, and plugged the charger in (from a Samsung Galaxy Gio - 5V 700mA)

The phone said "Sony Ericsson" then the branding "Rogers", after which it turned off. The Charge LED is not functional.

The only way I could start the phone is after a battery pull.

If I just press and hold the power button, the phone vibrates and just does nothing, occasionally it will boot to the "Sony Ericsson" then "Rogers" and then the screen turns off. Again, pressing the power button does nothing.

If I hold both the Menu and Back keys, the phone will boot into the OS, be detected by the OS, but only for a second, as about 3 seconds later a progress wheel comes up - says "Activating Phone" and then just black screen.

I can go into the "flash mode" by turning the phone off, holding the back button, then plugging in the USB cable, the LED turns green.

The problem is that I am unable to find drivers for this mode so I can use flashtool to flash a custom ROM on it (or a generic ROM)

I have installed some Sony Ericsson PC Companion, installed the "Support zone" but it can only detect my phone for that split second it is actually on "with the back + menu button combination", then disconnects.

I looked for SEUS But it tells me that it is not available for the x10

I will try the flash tool, but not sure, since last time I tried it (older ver) it told me to connect the phone in USB debug mode.

Any ideas? am I screwed?

Thanks!

---EDIT---

Never mind, I found the SEUS, however I have a problem.

When I try to flash X10a_1.0_2_1_A_0_435.ftf the X10FlashTool gives me this log:

That would be all nice and all (to turn on unknown sources and debug) but I can't as I can't even boot the OS anymore, just the flash mode (usb and back key)

27/040/2011 20:40:27 - INFO - turn on Unknown Sources and Debugging

That would be all

---------another update-----------

I have used the SEUS, looks like its super screwed. SEUS found an update to my phone, downloaded, installed it, and now I am screwed.

There is nothing I can do that makes the phone turn on at all - well I mean I can press the power button and then the phone vibrates and the LED flashes green for a split second. Then nothing. The screen does not even turn on at all. I have tried every combination I can think of and am out of options.

Any ideas as to what is messed up?
