aml_upgrade_package.img extract

[calc]

Thought this might be useful for someone, I whipped it up tonight so I don't have to use Windows to extract the files anymore.

#include <errno.h>
#include <inttypes.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <arpa/inet.h>

uint32_t convert(uint8_t *test, uint64_t loc) {
  return ntohl((test[loc] << 24) | (test[loc+1] << 16) | (test[loc+2] << 8) | test[loc+3]);
}

void main(void) {
  FILE *fileptr;
  uint8_t *buffer;
  long filelen;

  FILE *f;
  char *filename;
  uint64_t record;
  uint64_t record_loc;
  uint64_t file_loc;
  uint64_t file_size;

  fileptr = fopen("aml_upgrade_package.img", "rb");
  fseek(fileptr, 0, SEEK_END);
  filelen = ftell(fileptr);
  rewind(fileptr);

  buffer = (uint8_t *)malloc((filelen+1)*sizeof(uint8_t));
  fread(buffer, filelen, 1, fileptr);
  fclose(fileptr);

  for (record = 0; record < (uint8_t)buffer[0x18]; record = record + 1){
    record_loc = 0x40 + (record * 0x240);

    filename = (malloc(32));
    sprintf(filename,"%s.%s",(char *)&buffer[record_loc+0x120], (char *)&buffer[record_loc+0x20]);

    file_loc = convert(buffer,record_loc+0x10);
    file_size = convert(buffer,record_loc+0x18);

    f = fopen(filename, "wb");
    if (f == NULL) {
     printf("ERROR: could not open output\n");
     printf("the error was: %s\n",strerror(errno));
     free(filename);
     continue;
    }
    fwrite(&(buffer[file_loc]), sizeof(uint8_t), (size_t)file_size, f);
    fclose(f);
    free(filename);
  }
  free(buffer);
}

Building a new image is a bit more complicated so I'm going to wait until after I port CM13 before bothering with it.

Nice script calc



Here you all can find a full documentation on how to use/compile this c script with linux.

And I think this script should moved by one of the mods to the sub forum Knowledge & Tutorials.
Because here it fades completely next to the seal attraction (ROM).

Notice: Moved topic at your request. Left one week redirect. -RISCy Dude

Nice tool!!

What is the license of this code? GPL? BSD? or other?

I ask this because I would like to add it as a package for openSUSE (or inside an existing package). With your nickname/name and link to this page of course! Or a link to a git tree if you have one.
