Here is the current firmware.iHAS424-32A-ZL1P.rar.
Btw, the drive is an iHAS424-32A. Looking at my previous post I can see I got my models in a muddle.
I find the new numbering scheme very confusing. Some ppl say the iHAS424-32 is a rebadge of an optiarc, but for me all the mediatek tools such as ltnflash, eeprom utility and flash utility work fine.
