[Q] Samsung Galaxy Quattro (Win Duos) Invalid IMEI

I purchased a new Grand Quattro from Hong Kong. But now when I start the phone it shows "Invalid IMEI". Due to which I am not able to dial or receive any calls.
I have tried inserting several different codes like *#*#3646633#*#* and *#*#889988#*#* to try to enter the Engineering Mode and reinsert the IMEI but the codes are not working. Is there any other way I can solve this problem?
Thanks for the help. . . . Your answer would be much appreciated

Hi,
Thanks for using XDA Assist Check if you sim is correctly inserted or not else remove sim and add back again if that doesnt work go to Settings --> About Phone --> Device Info and see if IMEI No is Visible or you can check by dialing *#06# and see if its visible or not
Please DONOT post your IMEI No here just check and see
Good Luck!

Not registered on Network / Emergency calls only (Galaxy Trend plus GT-S7580)
Thanks but i have done it all but still not working,
the phone detects the sim card and the network icon shows that the SIM card is inside...but still Not registered on Network and Emergency calls only....
I need more help please....thanks

Is your IMEI No Displayed ?? Because if it is not displayed then your EFS Partition is Currupted ... If you have EFS Backup you can restore it but if you dont have then you have to take your device to Service Center of Samsung
Good Luck!

Hello dear ,
Try to reflashing stock firmware for device , its there on sammobile & on Samsung-updates ok
Thank You ,

Phone model and authenticity is unknown

Hello,i have been trying to flash stock firmware on my Galaxy S6 but i haven't been able to do it.While i was digging a solution i noticed that i can't tell which variant of the S6 my phone is.I have been trying to flash SM-G920F firmware until now.I bought the phone 5 days ago at a local mobile shop&service.The real problem now is that i can't tell what has happened to this phone before i bought it.
Back cover of the phone says that my phone is SM-G920F.
It is shown as SM-G920F in phone settings too.
When i enter download mode,it says my phone is SM-G920P.
I have downloaded the "Phone info" app and it says my phone is SM-G920P.
The IMEI is the same everywhere(in the back of the phone,in settings,in "Phone info" app,when i dial *#06# etc.)
I tried looking the IMEI up online and imei.info says my phone is SM-G920F,however the S/N number is not the same as in the back of the phone and in "Phone info" app.The phone settings also show a serial number that differs from the back of the phone and that number is the same as the "Phone info" app number.
Can someone help mee?
