How to back to oryginall bootloades

Hi all
I installed opie 0.9.1rc1, first, I serload blupdater.img, second I send 
system image with serial port, all works very fine. Now, I`d like come back 
to WinCE and I do:

boot> set override = 1
	setting param <override> to value <1>
boot> pflash 0 40000 0
	addr=00000000
	len=00009C40
	protect=00000000
	Protect=00000000
boot> load bootldr
	partition bootldr is a bootldr partition:
	requiring a bootldr or parrot image.
	After receiving file, will automatically uncompress .gz images
	loading flash region bootldr
	using ymodem
	ready for YMODEM transfer...
	362F95577901AFF5C29BA77867A9D33B simpadSL.rom
	00022EC0 bytes loaded to C0000400
	wrong magic: E3A01E27
	parrot word 0 ->0xE1A00000
	Expected ->0xEA0003FE
	parrot word 0x1000 ->0x55AA5A5A
	Expected ->0xE321F0D3
	You must load wince BEFORE loading Parrot
	Not loading invalid bootldr into flash

I used simpadSL.rom and simpadCL.rom from sourceforge.net

And now I dont know what I must do for come back to win_ce, I try serload - 
nothing, I change serial to 38200_8n1 - nothing, I try connect pin1 and 2 - 
nothing.
Please help, how can I come back to old bootloader (I dont have CF)
Sorry about my very bad english
Kris
