Hi !

Does anyone know how to remove a *.prx file into flash0:/vsh/module directory.
until 3.71m33 this directory is Hidden and in ReadOnly mode

I just want to be able to delete/replace some files in this folder but... that's doesn't work.

ex:

I juste make a dummy.txt file inside vsh/module via Windows
With sceIoRemove I can't remove this file...

sceIoRemove return no error ...

Any idea ? flash0 is already assigned with 0777 attribut
it's possible to replace vshmain.prx and paf.prx via an eboot in kernel mode ?

Use sceIoChstat to change the file attributes,

thanks but that's doesn't work...

so I can't remove or replace file in flash0:/vsh/module directory

sceIoRemove("flash0:/vsh/module/paf.prx")
sceIoOpen('flash0:/vsh/module/paf.prx", PSP_O_RDONLY, 0777);
return error...

So if I can't remove or open it's impossible to me to write a new one.
I just want to finish a Theme Flasher who can flash paf.prx and vshmain.prx

So if I want to copy a dummy file in flash0:/vsh/module/ dummy file go in vsh/podule ! WTF ?

i'm in PSP1004 FAT 3.80M33-5 with Kernel 1.50

sceIoChstat does work because I'm using it for exactly the same reason in my own theme flasher,

You need to use SceIoStat and sceIoChstat before sceIoRemove

... *cry*

ok I just try to make a fonction

Code:
void Remove_file(char * Delfile)
{
int file_exist,test_del;;
file_exist = sceIoOpen(Delfile, PSP_O_RDONLY, 0777);
   if (file_exist>=0){
      SceIoStat stat;
      memset(&stat, 0, sizeof(SceIoStat));
      sceIoGetstat(Delfile, &stat);
      stat.st_attr &= ~0x0F;
      sceIoChstat(Delfile, &stat, 3);
      test_del = sceIoRemove(Delfile);
         if (test_del<0){
            pspDebugScreenSetTextColor(0x000000FF);
            printf("%s - Cannot delete file\n", Delfile);
         }
         else {
            pspDebugScreenSetTextColor(0x0000FF00);
            printf("%s - File Deleted OK\n", Delfile);
         }
   }
   else {
   pspDebugScreenSetTextColor(0x00303030);
   printf("%s - File not found or already Deleted\n", Delfile);
   }
}


but

Code:
Remove_file("flash0:/vsh/module/vshmain.prx");
Remove_file("flash0:/vsh/module/paf.prx");


return "File not found or Already Deleted"

I've try without the file_exist test but same way... the PRX was not deleted...

any idea ?

Flash0 is unassign and re-assigned without error
Code:
if (sceIoUnassign("flash0:") < 0)
   printf("F0unassign: Error | ");
if (sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0) < 0)
   {
      printf("F0assign: Error\n");
   }


and i'm in
Code:
PSP_MODULE_INFO("flash", 0x1000, 1, 1);
PSP_MAIN_THREAD_ATTR(0);


tested in 0x0800 too

This is what I have,

Code:

PSP_MODULE_INFO("Write2Flash380", 0x800, 1, 1);
PSP_MAIN_THREAD_ATTR(0);
PSP_HEAP_SIZE_MAX();


Also using the code I posted before seems to work fine and has been tested on 3.80m33-x and 3.90m33-x

Try closing the file after you have checked that it exists,

Then do the attribute change and delete,

i hav by-pass this fonction.
Eboot not check if file exist, just check if file sceIoRemove return no error.

Code:
void Remove_file(char * Delfile)
{
int test_del;;
      SceIoStat stat;
      sceIoChstat(Delfile, &stat, 0x0003);
      test_del = sceIoRemove(Delfile);
         if (test_del<0){
            pspDebugScreenSetTextColor(0x000000FF);
            printf("%s - Cannot delete file\n", Delfile);
         }
         else {
            pspDebugScreenSetTextColor(0x0000FF00);
            printf("%s - File Deleted OK\n", Delfile);
         }

}


i'll try to install 3.90M33 ... sniff i love my 3.80...

[edit]
Same way in 3.90M33-2 k1.50v2

I just did a few tests with the code and it seems I'm also now getting strange results,

I created 4 read only txt files and tried to delete one and it would not delete until I tried to delete the 2nd time,


But I can then delete any of the other read only files in one go,

Seems strange to me so I will try to work it out,

It's wierd because the theme flashing works fine well it seems to be but when in the file browser (another feature of the app) I sometimes get wierd results using my file copy, file paste and delete features,

It's strange, lol

I'm going to have to take a look at it again when I'm not so sleepy,

Try this code, works for me.

Code:

PSP_MODULE_INFO("Your App Name", 0x800, 1, 1);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_VSH);
PSP_HEAP_SIZE_KB(21000);

void ReassignFlash0()
{
   int flash0_unassign, flash0_assign;
   
  flash0_unassign = sceIoUnassign("flash0:");
  flash0_assign = sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);
   
   if(flash0_unassign < 0){
         pspDebugScreenClear();
         printf("  Error: Unassigning Flash0\n");
         sceKernelDelayThread(500000);
         sceKernelExitGame();
      }
   else if(flash0_assign < 0){
         pspDebugScreenClear();
         printf("  Error: Assigning Flash0\n");
         sceKernelDelayThread(500000);
         sceKernelExitGame();
      }
      else{
            printf("  Flash assigned\n");
         }
}

void removeStatus(const char *file)
{
   int fileDelete;
   
   SceIoStat stat;
   memset(&stat, 0, sizeof(SceIoStat));
   sceIoGetstat(file, &stat);
   stat.st_attr &= ~0xFF;
   sceIoChstat(file, &stat, 3);//Hidden Stat
   sceIoChstat(file, &stat, 4);//Archive Stat
   sceIoChstat(file, &stat, 6);//Read Only Stat
   
   fileDelete = sceIoRemove(file);
   if(fileDelete < 0){
      sceKernelDelayThread(300000);
      printf("%s: Deleted unsuccessful", file);
   }
   else {
      sceKernelDelayThread(300000);
      printf("%s: was deleted successfully", file);

Just tested, same way...

I have flashed a dummy.txt file in flash0:/vsh/module but Cannot delete

Code:

PSP_MODULE_INFO("fnof", 0x800, 1, 1);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_VSH);
PSP_HEAP_SIZE_KB(21000);


int main(void)
{
   pspDebugScreenInit();
pspDebugScreenClear();
pspDebugScreenSetTextColor(0x00FFFFFF);
   int flash0_unassign, flash0_assign;
   
  flash0_unassign = sceIoUnassign("flash0:");
  flash0_assign = sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);
   
   if(flash0_unassign < 0){
         pspDebugScreenClear();
         printf("  Error: Unassigning Flash0\n");
         sceKernelDelayThread(500000);
         sceKernelExitGame();
      }
   else if(flash0_assign < 0){
         pspDebugScreenClear();
         printf("  Error: Assigning Flash0\n");
         sceKernelDelayThread(500000);
         sceKernelExitGame();
      }
      else{
            printf("  Flash assigned\n");
         }
printf("\n\nFlashage en Cours...\n");
sceKernelDelayThread(100*1000);
Remove_file("flash0:/vsh/module/dummy.txt");
sceKernelDelayThread(1000*10000);
pspDebugScreenSetTextColor(0x00FFFFFF);
printf("Operation terminee");
return 0;
}

void Remove_file(char * Delfile)
{
//int file_exist;
int test_del;;
//file_exist = sceIoOpen(Delfile, PSP_O_RDONLY, 0777);
//   if (file_exist>=0){
   SceIoStat stat;
   memset(&stat, 0, sizeof(SceIoStat));
   sceIoGetstat(Delfile, &stat);
   stat.st_attr &= ~0xFF;
   sceIoChstat(Delfile, &stat, 3);//Hidden Stat
   sceIoChstat(Delfile, &stat, 4);//Archive Stat
   sceIoChstat(Delfile, &stat, 6);//Read Only Stat
      test_del = sceIoRemove(Delfile);
         if (test_del<0){
            pspDebugScreenSetTextColor(0x000000FF);
            printf("%s - Cannot delete file\n", Delfile);

@Alree - This worked fine for me,

Code:

SceIoStat stats;
memset( &stats, 0, sizeof(SceIoStat));
sceIoGetstat( file_path, &stats);
stats.st_attr &= ~0x0F;    // This line is differant from the example given by Gh0st-UPMS
sceIoChstat( file_path, &stats,  3);
sceIoChstat( file_path, &stats,  4);
sceIoChstat( file_path, &stats,  6);
sceIoRemove( file_path);

So it's maybe a SDK or compiler problem, try to update PSPSDK.
