Hey, thanks for the input on arm7_go. I'll try i tout....but when you said before 0x00000048, what exactly did you mean? The thing is, anyway, when I assemble it with gas there is no opcode there that has 0x48 in it...or is this not what you mean?
Thanks, -chronic

Chronic,
Here is the script I use to compile with gas (I am not expert... it is my experiments) :
$ cat compile.sh arm-elf-as.exe -mcpu=arm7 -o test.o test.asm arm-elf-objcopy.exe -I elf32-little -O binary test.o test.payload
Then for the moment, I modify test.payload to add its size as a little endian double word manually (using WinHex) For your example : the size of your code is 72 => 0x48. So I add 48 00 00 00 just before the payload.
After that I upload the payload with your iRecovery -f Then arm7_go :)
I just tested to make a payload with just a RET (MOV PC, LR) in it and it didn't crashed my ipod. It means nothing but... I continue !
I wish we can talk by email. How can I send my email to you in a secure way ?
