The essence of the question is not clear. Exactly how Phison MPALL doesn't work. With what error. There is also the UPTool_Ver2094(Release)_20150909 utility. And the system for repair is desirable X32. There may also be hardware problems with the flash drive.
Device Name: 2307 Boot ROM Product Model: 2307 PRAM
This sounds like NAND issue, it seems to boot into 'safe mode' (and so controller works) and can not talk to NAND and so not load firmware. NAND may be kaput and then no amount of firmware flashing would be of any help.
MPALL with a non-native binary code for this NAND Hynix will not take off ... UPTool has auto-selection of the NAND code. But it is more suitable for NONAME flash.
