If you have a untouched bricked stock rom on your device with a stock SPL don't try but just return it for repair.
More info about HSPL you can find here, credits to Cotulla and Bepe.
Please follow this steps carefully.
[B]01.Download the rom here:
02.) Download attached MTTY
03.) Make a folder on your desktop in C:\
04.) Put downloaded MTTY unzipped in C:\Recovery\.
05.) The unzipped T-MOUS 2.02 you copy to C:\Recovery\TMOUS202\.
06.) Extract the TMOUS 2.02 exe by right klicking it and choose extract.
07.) Remove all files extracted exept RUU_Signed.nbh
08.) Rename RUU_Signed.nbh to LEOIMG.nbh and copy it to your device storage card.
Now next steps I've used Windows XP and don't know how it works in other OS so you need to find out yourself sorry.
09.) Open MS ActiveSync\settings and disable USB connection.
10.) Take out sim card and storage card from your device.
11.) Next put your device in bootloader (volume down button + Power button) and connect to your pc.
12.) Open MTTY in the directory where you have copied it C:\Recovery\.
13.) Port you choose 'USB'and press ok.
14.) In the window that follows next type 'Task 29'(without the quotes) and press ENTER.
15.) MTTY will give you some errors in next Window but please ignore.
16.) Next disconnect your device from USB, take battery out and put your storage card in.
17.) Put battery back in and put the device in bootloader and follow the onscreen instruction to flash.
If this method worked for you then download a shipped rom that came with
your device from the factory website using your device serial and flash this rom from storage card
Follow the same steps (6,7,8) as you did before with this rom to get LEOIMG.nbh
Your back to factory rom.
Reminder, in order to flash a cooked rom again you need to flash Bepe and Cotulla's HSPL.
This method worked on a bricked European HD2 which gave us a radio fail message.
I'm pretty sure it will work for your TMOUS too.
A special thanks to Xmoo for the mirror and standbye help unbricking the device.
