IMEI lost after flashing K4505 with E182E update

[xman750]

Hi,
I've downloaded a firmware update: K4505_to_E182EUpdate_11.831.06.01.464.B427.exe

from DC-Files to convert my k4505 dongle into E182E so it can be recognised by a router which only supports E182E. Now the router can see the modem correctly but the IMEI number and serial number are both gone from the dongle. I've flashed it back to K4505 but the IMEI and S/N are still gone.

Have anybody here converted K4505 successfully to E182E ?

ok I've managed to restore the IMEI using QPST and this:

<....> guide however I was only able to write the IMEI when modem was flashed with E182E firmware however after upgrading it back to K4505 the IMEI stays ok so the problem is solved now
