Looking for un-pack pack perl scipts plesae

[Guest xzyk]

Could some kind dev on here please post (or pm me) the boot.img unpack and pack perl scipt for SF 2.1 please. Hexedit is a real pain, I'm sure someone on here must have a perl scipt for this.

Thankyou.. :)

Use split_bootimg.pl from here. Note for when re-packing: base on Blade is 0x03000000.

Use split_bootimg.pl from here. Note for when re-packing: base on Blade is 0x03000000.

thanks Art Too, I'll give it a go..

EDIT: managed to get the mkbootfs and mkbootimg binaries loaded. All seems to be working fine except:

1. I've tried everywhere to pass the --base 0x03000000 parameter, but no joy. I can make the new boot.img fine but not when i try to pass this address.

2. The final new-boot.img is only 2.4MB whereas the boot.img extracted from the nandroid backup is 4.5MB. The # cat /dev/mtd/mtd1 > /sdcard/mtd1.img

also results in a 4.5MB file on my sdcard.

EDIT2: looks like i had a binary of mkbootimg that would not accept the --base paremeter. Downloaded a new one and now it packs fine with the address passing, however my second query still stands. Why is the packed new-boot.img only 2.4MB?

Any help please would be appreciated..thankyou..

EDIT3: It's ok, the file is supposed to be smaller. The end of the original boot.img is padded with 0xFF, so all is fine. I fastbooted the modified boot.img and everytihng worked as expected.

Thanks Arr Too, took a bit of reading to get there but finally managed it.
