ANY HELP????

MY PDA DOESNT START THE BOOTLOADER

on JULY 1 I SAID:

(Sorry for my bad english) I have been for 2 complete days trying to solve before post this new thread. Now, the explanation:

I have a Spanish Movistar company HD2.

To enter in bootloader mode I have to be a few seconds (or minutes, it depends...) without battery. When I get into bootloader mode I see:

_______________

PB81100 HX-BC

SPL-2.08.0000 8G XE

MicroP(LED) 0x05

MicroP(TOUCH) 0x40

Serial

_______________

So I supose that it isn´t the HSPL installed.

Sometimes when I simply switch on I see HTC logo with white background (I supose that is because it has the task29 made.

When I left the device without battery few seconds (or minutes) and I get into again and I switch on I see too the HTC logo with white background.

I have try to flash some roms through microSD card and the result is allways the same: It changes the screen into a grey and I see "Loading..." but it stays like this infinitely (I have try to wait more than 20 minutes). I have try this with original Movistar Company ROM, original HTC ROM, some radios (more than 6 types), some coocked ROMS (including arthemis, BSB beast, Energy), and the result is allways the same, stays "Loading..."

I have try to flash through PC. CustomRUU Recognizes the device but when it starts to update the device doesnt change screen or sometimes looks like pixelated screen, and on the PC appears like new hardware found (qualcomm CDMA Technologies MSM) and update through pc doesnt start. I have try too when It appears like new hardware found to remove the battery and start on bootloader mode, but update neither starts.

I have try to make HSPL (2 and 3) and the result is allways the same: recognizes the device and on bootload screen apears "USB" in the white part. HSPL tells me what SPL I have ( 2.08.0000|| ) and let me choose 2.08.HSPL BUUUUT when I push continue in the device nothing happens, on the PC appears like new hardware found (qualcomm CDMA Technologies MSM) and HSPL gives me an error (sometimes one sometimes other):
