About EAP Hdd Key

• sceSblGetEAPInternalPartitionKey((__int64)&unk_FFFFFFFF836C0000, &unk_FFFFFFFF836BC010, a2, a3, v7) )
• seems to contain 2 buffers
• unk_FFFFFFFF836C0000 (0x70) <- encrypted eap_hdd_key ?
• unk_FFFFFFFF836BC010 (0x70) <- decrypted eap_hdd_key ?

you have right

 v7 = icc_nvs_read(0LL, 4uLL, 0x200LL, v2, &enc_eap_key_);
 if ( v7 )
 {
   v12 = v7;
   printf("icc_nvs_read failed: %d\n", v7, v8, v9, v10, v11, v19);
   panic("eap key not available", v12, v13, v14, v15, v16, v20);
 }
 printf("g_crypt_deferred_init: calling CCP\n", 4LL, v8, v9, v10, v11, v19);
 v12 = &eap_key_;
 if ( sceSblGetEAPInternalPartitionKey(&enc_eap_key_, &eap_key_) )

bank 2

bank2 isnt probably backup bank its accessed by sub_FFFFFFFF827D2F50:qafutkn ??? icc_nvs_read(1LL, 4uLL, 0x0a00LL, 0x190uLL, &data_ptr);

whole nvs storage is accesible via /dev/sflash0s0x34 and size is 49152bytes probably
