no te sé decir donde lo leí, pero seguro que en un hilo de la sección scene de este foro, en alguno sobre hitachi supongo que son los que más suelo leer..
el iextreme ya sé que no lo has hecho tú, me refiero a personalizarlo con tu key.
Prueba a seguir un manual de jungleflasher para crear tu iextreme 1.51 con tu key y luego pruebas a cargarlo y grabarlo con el toolbox 4.8
En ls instrucciones del programa habla de tu error:
Maximus 360 Firmware Toolbox v4.8
>> Maximus released a new version of his 360 Firmware Toolbox(info)(info).
What's new/fixed (since v4.6):
* ADDED: Custom Spoofing Option on "Tools->Spoof Firmware" option (it asks for your 96 bytes inquiry.bin), this could be safer for spoofing drives to Liteon because appears Liteon drives have per-drive specific inquiry response.
If you lost you inquiry.bin file and cannot redump it, then go ahead with listed Liteon spoofing option (it will work but you will not have the factory value).
* ADDED: You can now open key.bin file from main window instead of manually type the key (will ask for a 16 bytes file).
* FIXED: Clicking on firmware file didnt open properly on toolbox.
* ADDED: Spoofing drives to Liteon DG model
* ADDED: Detect/Remove Hardware (DVD-ROM) (on File Menu)
* ADDED: Ixtreme 1.4 No-Check Bit firmware for 79 Drives
* FIXED: Several bugs.
* Note: The No-check bit option for 79 drives is not set as default firmware on Smart hack patcher option, you need to choose it from the list on the Special Firmwares section, the reason is it could be unsafe and lead to M$ detection.
*Note - At this time, it is currently not confirmed safe to use a samsung or hitachi in place of the lite-on. This is due to a specific identification tag that is generated with the SS. There will be firmwares released in the next few weeks to account for the correct values! -Iriez
