Can QPST be used to restore "Serial Number" of 3g usb modem Huawei UMG 1831 ?
 

hi,
I have a huawei umg1831 3g gsm datacard.
Some times ago I had flashed it with another
datacard firmware.
After that the IMEI and the SerialNumber were missing from the datacard.

Some how I managed to rewrite the IMEI to
NV_ITEM 550 in my datacard using QPST and
my IMEI is restored. But I am still unable to rewrite/restore
"Serial Number" to the datacard.

Can any one tell in which nv_item the serial number
is stored or any way to RESTORE SerialNumber in to the datacard.

regards
