P3600i cant get in bootloader mode

[learnig]

I can't flash or anything(get in 3 colour bootloader) for my P3600i.
I mean it is work but sometimes it hard reset by himself or freeze.
i just can get in USB or serial mode n write Ver.1.20 (with blank screen n just Serial or USB when i get in my cable)
radio ver.1.11
rom ver.1.11.00 WWE
So i decide to flash it.But when i want to get in bootloader mode,it freeze n hang.
n so when i run the ROMUpdateUtility.exe from [P3600i] HardSPL v1.1 files,just same result from anytype of this rom,when i try to flash
i must reset for it.
I had tried copy [P3600i] HardSPL v1.1 into memory card (SD or MMC) then run EnterBootloader.exe from P3600i explorer,just the same result.
Any idea?
i dont know what i must do anymore now.
Help pls!
Thx very much

Don't know what to say. I have a P3600 not a P3600i. And they are a bit different. Tried to enter in bootloader using: on/off button + camera + reset (presed with the stylus)?
