It doesn’t make any sense to me. If people can update the 24x to 40x drives, shouldn’t the upgrade work on all 32123 drives?
If you do all the thinks right that has to be done right, it should work. Read carefully: http://club.cdfreaks.com/showthread.php?s=&threadid=54277
And good luck.
It’s not a problem of doing it. I’ve used mtkflash many times before. But I get errors when using XSU1, both reading and writing and also with an error message “NO ADDITIONAL SENSE INFORMATION (000000)”
