[Q] Windows Mobile 6 Won't boot after first soft-reset !! Black Sceen !! PLEASE HELP!

Hi ! I have an Acer P300 Windows Mobile based device . I have tried to install Android on it ( i was able to install the rom from a device named GeeksPhone ONE which has the same hardware specs. ) , after the installation the screen was on , but all black . After that I've reinstalled my original FW . All went good , only that my phone wasn't reading my SIM CARD and no WI-FI connections ( although I was able to connect with the wifi at a point ).
After a Soft-Reset ( shutdown and startup ) the phone shows the Acer logo with the FW version , and after that the same black screen as with Android .
It might Android damaged my hardware ???
Now my device won't turn on at all .... No vibration on power button , no bootloader , nothing . Please Someone can help me ?? At least some notes ... One reply from you won't hurt !
P.S. Still waiting for some answer !
Now my device won't start at all ... Is completely DEAD !!! ...
If someone will want to answer , I need some help with the battery , I believe that is not charging anymore ! ...
Anybody with the same problem around here ?

Try downloading one of the root tools like srsroot which will let you boot into debug mode. That should restore your boot structure. Have you already tried this?
