unable to downgrade/upgrade rom

---

I have dopod d810, i recently flashed my device to LVSW 2.0.0.7, radio 1.41, and also HARDSPL.

Now i want to upgrade to LVSW 2.0.1.1 latest rom. But after so many times i have done the upgrade procedure, after reset, it keeps going back to the previous rom.

The upgrade seemed to be working. but when it finished, i still got the old rom...

I have tried SUPERCID unlock my device. but no luck.

even worse I tried to revert back to original dopod rom, still no luck.

There is no error when flashing, it wen from 0% to 100% without problem, just it keeps reverting to old rom.

anyone??
