iemi lost after cyano firmware

Flash with odin stock firmware - iemi ok
Flash with cyanomod - iemi lost
Any reasons for this? and the solution?
Flash rc4. Imei is not lost, just hidden. There is no problem with imei in rc4.

But play store just brings up an error "...could not be download due to an error"
For the Play Store, i had no luck too, will try to reflash the rom asap.

Guys, check the rom's dev thread, someone had posted a very efficient method which worked for me
I have already fixed it by reflashing the rom.

From your post history, you seem to have been trying to flash your device over to another carrier... It seems like something went wrong with that.
Have you tried using ODIN to flash the NC5 or NH7 basebands?
Yeah i did something like that, i have nh7 modem tried many modem, i can't get it back actuality this is the problem with octupos unlocking device, is there any way to get it back???
