Last attempt get first X10 working - XPERIA X10 Q&A, Help & Troubleshooting

Hi Guys,
I making a last attempt to get an old X10 working before I strip it for parts. If anybody has any new ideas, I'll give them a try otherwise I'm going to dismantle it to use the case and screen to pretty up my working X10 (dents and scratches).
History:
About a year ago, it started acting up and overheating on occasion and even at times it wouldn't charge.
After a couple weeks of this, one day it started freezing up on me. After I powered down it wouldn't restart. Dealing with tech support I tried using PC Companion and SEUS to try and repair the phone but flashing would always abort.
I've tried various versions of Flashtool and SEUS as they have been released and still haven't been able to get the phone to boot. PC Companion and SEUS always error out when trying to flash and Flashtool even though it completes will give a yellow triangle with exclamation point in it.
The one exceptions is when I flashed the newest X10a firmware with flashtool but unchecked the wipe userdata box. When I do this the phone will actually boot past the Sony Ericsson screen and perform the boot animation but... This is where it get's stuck and just loops the boot animation over every couple of minutes.
The only other piece of information that I can provide is that even though Flashtool will report a successful flash the complete firmware package including userdata, I believe that userdata is failing because of a timeout. Flashtool will sit on flashing userdata for about 5 minutes before completing.

after you flash the new x10 firmware you need to flash the new kernel and radio too!
that should stop the boot loop and maybe get it running again
you can find the radio and kernel ftf in the dev forum

When you flash the full ftf package with flashtool, the baseband (radio) and kernel are included. But..... Just in case I did try to flash the .71 package but it didn't make any difference.

did you try a seus when you got to the bootloop?
sounds like a probable motherboard issue

Yep, SEUS just fails to complete flashing the phone, I've just about given up on it. Last thing I'm going to try tonight is reseating all the modules inside it. Who knows, Maybe I'll do a tear down post while I'm at it. At the very least I'll have a collection of spare parts for my working X10

a lot of people here had motherboard issues

Ya, this was an early model x10a from when Rogers first introduced them.

Ok, figured out how to dissassemble the X10 using this guide and this is what I have laying out in front of me.

I'll try to reassemble it and if it goes OK, I'll go ahead and replace the display/touch panel on my working X10 with this one.

Nice pic, lol.

Ok, transplant worked. I now have the guts from my working x10 inside the undented and non scratched case of the one with the bad main board.
It's almost like having a new phone again.
