Running this tool will modify the bootloader sector of your device's flash memory. This is risky, and while the code has been tested and some checks are done at runtime, it may hard brick the modem.
The only way to recover it would be via. Ensure there is no risk of power outage while running it. Run the tool with argument 0 (disable) or 1 (enable). Running without any will show the current mode.
E.g.: will disable the signature (you want this if running custom firmware images): #./permstpatch 0 (SHA-1: 8dd5345024ba872788040eb51b5a1d2ad9f145b0) AC Series. The AC Series (vAC01, vAC02, ) are modified versions based on stock images, either to remove useless stuff or add new features, without having to resort to compile everything again. The sources are available, but getting them to work properly wouldn't be easy.
These will only run after. With your patched bootloader, you can either boot this image via (not permanent, for testing only) or burn it permanently to your flash. Remember, there is always a risk on every flash write operation. Some stuff from the original package needs to be removed to make room for the new files. No, it can't grow bigger than what the original FS was.
