Custom Firmware en PS3 con firmware oficial 4.82

La scene de PS3 sigue activa, y de que manera. Ya es posible instalar un Custom Firmware en PS3 desde el último firmware oficial, el 4.82 gracias al Team PS3Xploit.

Ojo, solo es compatible con el firmware oficial 4.82, ni inferiores ni otros Custom Firmwares. Tampoco es compatible con los modelos 3XXX/4XXX de PS3. Esto es, los últimos modelos Slim y los SuperSlim, ya que se brickearían.

Esencialmente lo que hace esta solución de software es parchear el CoreOS (o el Chip NOR/NAND) y cuando la PS3 se reinicie permitir instalar directamente un Custom Firmware, no siendo necesario hacer downgrade a 3.55.

Pasos a seguir para instalar un Custom Firmware desde el OFW 4.82

Los pasos a seguir son los siguientes:

  1. Poner en marcha un pequeño servidor web usando un PC o un smartphone. Usar una aplicación web personalizada con pequeños cambios en el Javascript.
  2. Extraer los archivos a la carpeta root de servidor http:
    1. Para usar el servidor miniweb.exe es necesario crear la carpeta htdocs.
    2. Los archivos *.html y *.js incluidos en el zip deben ser copiados y movidos a la carpeta htdocs.
  3. Copiar el archivo “flsh.hex” a la carpeta raíz del pendrive.
  4. Poner un pendrive formateado en FAT32 en el puerto más cercano al lector Bluray de la consola (/dev_usb000).
  5. Doble-comprobación a nuestra memoria flash en el XMB para estar seguros de que se muestra bajo Música, Fotos, Vídeos, etc.
  6. Abrir el navegador web de PS3 y su ventana de direcciones para escribir la dirección IP de nuestro servidor (y el puerto, si no es el 80) y presionar el botón START.
  7. Seleccionar el botón apropiado para nuestra consola y esperar a que la consola se apague. No interrumpir el proceso una vez iniciado.
  8. Una vez la PS3 se haya apagado, reiniciarla e instalar el CFW según el OFW que tenemos. Si la instalación desde el XMB no funciona, iniciar en modo recuperación e instalar desde ahí.

=========================
PLEASE READ FIRST:
It’s essential not to flood the browser memory with junk before running the exploit. The reason for this is that due to javascript core memory usage limitations we are scanning several times a small range of browser memory (a few Mb) to find some essential data in RAM, if the memory is flooded then the range to scan becomes much larger & the probabilities that our data is found in the smaller range decrease dramatically….
So in short, never use the browser or set a homepage you cancel before running the exploit!
If you need to, set the homepage to ‘blank’, close the browser then reopen it to start the flash dumper
Usage Tips:
1) Try using a LAN connection or a solid WiFi connection during exploitation. A weak signal can cause problems.
2) If the exploit takes more than 5 minutes to work, reload page, browser, or restart console and try again.
3) If you are using a LAN connection and experience network issues, make sure all cables to router are in working order.
======================
Steps:
1. Setup a small Web server on pc or smartphone. A custom miniweb application has been created by Aldo, and supplied to host files if you would like to use it. Don’t come to us for explanations about how to run a http server though. Google it.
2. Extract the files from release to your http server root folder.
3. Put a FAT32 USB key in port closest to BD Drive (/dev_usb000).
4. DOUBLE-CHECK your flash drive on XMB to make sure it shows up under Music, Photos, Videos, etc.
5. Open the ps3 browser, press start & write the ip address of your server (and the port if not 80).
7. Click on the button and wait for PS3 to power down. DO NOT STOP THE PROCESS ONCE STARTED!!
8. Once PS3 has powered down, the NOR flash memory dump can be found on the USB device in a file named ‘dump.hex’.
