How to create bml4 dump

cat /dev/bml4 > /sdcard/bml4

Now create zImage
Run any HEX editor and open bml4


at address 0x24 - you can find magic number (DWORD) - 0x016f2818 = zImage magic number
and
at address 0x2C - size of zImage (for example = 0x004e34bc)
simple resize bml4 for this size and save as zImage

next put it to tar and flash by Odin

Darn, I'm too deft to understand this.
I got the bml4 on my computer, opened it with an hexeditor and checked the size ( 0xe10f2000).
But how do you resize the file to that length and what do you use the magic number for?

Magic number - it's only to identify zImage
For resize:
1. I use Hex Editor Neo
2. I main neum "Edit->Change File size" simple enter size from offset 0x2C

Leshak, I did exactly as said, then I renamed the file to zImage, and put into TAR with 7-Zip. When I try to reflash this original kernel on my phone, and select the TAR under PDA Tab in Odin, i get an "Invalid Image Type" error.

Please help

You should RESIZE it! before put into TAR!

and I don't know about 7-Zip's TAR, I use tar from Linux.
