I have android boot image which needs to be patched evertime I flash a kernel.
The patching includes adding 4096 bytes to the boot image using a hex editor (I used ghex), which is very tedious process because you have to manually add 4096 numbers to the file by hand. So, I want to make a script to automate the process.



It is not like simply editing files, it requires hex editor.
