invaild imei (MTK6577) Bug

hello members of xda devs after full reset (deleteing all data)

MTK6577 Chip , Android 4.0.9 (Bedove i5) its my device
Thanks for helpers
I join the thread, I have this on Lenovo A660. How to recover IMEI, I cannot use any network SIM card.
I had this problem too but I had a backup of my imei so I could restore it with mtk uncle tools. Maybe if the imei is written on the back of the phone or somewhere inside of it you could edit an imei backup so you could restore it.
Yes, but how to do it? Of course I have IMEI nr of the phone.
You will not find any help here on this. The only way XDA supports on fixing an IMEI is by restoring a backup that should have been made before doing anything to the device.

Lost my imei on z2 & no signal

Hi every body... This my first participation here and i don't know if it is the right place to share my problem with..
But i hope you help me with it.. So here it is: my friend install a new rom for my sony z2 but i think he did it in a wrong way cause after that there was a message tell me the the software update had failed.. So i didn't know what should i do.. And i tried to fix theat issue using pc comopanion and it seems that fixed the problem until i login after it finished to find out that the phone lost its imei number and i can't enter to my mobile network at all .. ie no signal and mobile not recognize sim card... So how can i fix this damm problem.. ?? i still have imei number on word file if this can help..
And thanks any way
I think your friend should install z2's original rom then it may be fix . Most probably your new rom has bugs so phone does not recognize your sim card .
