pip install exheader

Usage

from exheader import Exheader

exh = Exheader()

# Load exheader from file
f_in = open('exheader.bin', 'rb')
exh.unpack_from(f_in.read())
f_in.close()

# Print the application tite
print(exh.sci.app_title)

# Change the application title
exh.sci.app_title = 'MyApp'

# Print allowed SVCs
print(exh.aci.arm11_kernel_caps.svcs)

# Add SVC 0x70
exh.aci.arm11_kernel_caps.svcs.add(0x70)

# Write modified exheader to file
f_out = open('exheader_out.bin', 'wb')
f_out.write(exh.pack())
f_out.close()
