Due to the lack of proper checks after exiting the ROP chain, it is possible in some cases to obtain a success message despite an operation failure. For instance, if you choose a path where no device is plugged in, a dumper page will still display a success message despite the fact the dump save could not work. This limitation has already been addressed, the added operation checks will be part of an update to these PS3Xploit tools which will be released in the coming weeks, that update will be final, no more will come after it.
