me too its happened to me on 18-July-2015 and my
- non rooted g920f
- IMEI changed to 350000000000004
- simcards not working ( not registered on network )
- i have signal bars without simcard !
- and when i reainstalled rom i found updates about 66mb i dont know because of updates or e have big prob here
any solution plz
Maybe a defective SIM card.
Perhaps a temporary network fault.
Your IMEI is corrupted then you are cut off the network!
If you have EFS (IMEI) partition backup try to restore it , for example by this app and you are done!
If you don't have backup of EFS partition you need to send phone to samusng service. (only samsung can't restore your original IMEI number)
regards!
Correct the phone was blocked and i've returned it to the seller. Ebay sucks.

Is it giving a message when you remove your SIM card from running S6 ? asking for reboot or something like that I can't remember correctly ? If it's not giving the message seems like something wrong with your SIM bay ?

None of the secret codes would run on my Galaxy S3 Verizon SCH-I535 .

PLEASE HELP !!!
None of the secret codes would run on my Galaxy S3 Verizon SCH-I535 (Android 4.4.2 ) .
Everytime I run a code it gives me an error message ( Connection problem or invalid MMI code).
Tried almost all secret codes but no avail, even the code to check the IMEI wont work and gives the same error message.
FYI - I got it unlocked in India.

Pretty sure dialer codes were disabled due to security concerns several years ago. Something about a particular one being used to factory reset phones. So, there's no way around that.

So what should I do to make them work on my phone ?
Kindly help, I would really be grateful of you.
It is weird that none of the secret codes would run on my phone & all I get to see is ( Connection problem or invalid MMI code), I have tried adding a "," after the code but it didnt work either.

As stated in the previous post they were disabled years ago. There isn't a way to re-enable them

Connection problem or invalid MMI code

Hi I currently have the HTC Desire 510 android phone running kitkat 4.4.2 but however when I try to check the Sar level on my phone by going to the dialer app on my phone and putting the following *#07# I keep receiving the following error message (Connection problem or invalid MMI code). I have searched google for the answer but I have had no luck. I do not know how to fix this. Any help to this question would be appreciated thanks.
