Connection Problem or Invalid MMI Code
I have a Coolpad 7260 phone which has been working perfectly until today.
When I made upgrade to it and after booting I got this message:
USSD code running. Connection problem or invalid MMI code.
The phone still works perfectly except for this issue. My broadband connection via Wi-Fi is being received strongly by the phone.
and i cant go to the download mode
Does anyone have any idea how to resolve this please? Thank you.

What was the upgrade exactly? Can you roll-back?
yes I gave it the original software by usb
first off when i input the code i get nothing, nothing happens.
when i call the code this appears "Connection Problem or Invalid MMI Code"
i searched for solutions but nothing
help pls
Codes only work on touchwiz firmware, aka. Samsung stock or modded if I remember correctly.
Also, if you're using other dialer than original you can get same error.

I have tried both cm 10.2 and pac and every time i try to change the call forwarding settings i get "Call settings error Network or SIM card error." I also get "Call forwarding Connection problem or invalid MMI code" when i try to punch in a code to change call forwarding. Any help would be greatly appreciated.
Btw I am on a P769.
UPDATE
I went back to 20f and it works I can access and change call forwarding and use mmi codes but when i went back to CM or PAC i get the errors again.
Please help!
Yep, didn't work for me too on CM10.2. Probably something with RIL. There is an error in the radio log but it's cryptic. Not sure I can fix it easily, RIL files are proprietary.
Can somebody try Call Forwarding on p760 CM10.2 ROM and see if it works?

I know when I had the galaxy s2 i could flash radios with the rils removed. Is that possible with this phone and would that fix the problem?

Hi, I recently pruchased a Samsung Galasxy S6 Edge and bought a unlock code from eBay. When trying to enter USSD codes I get the same error everytime 'Connection Problem or Invalid MMI Code'.
I have looked online and tried the common fixes but no joy. Even trying to run a basic *#06# gives the same error. I have tried using a combination of + and , etc before the first digit and after the whole string but still get the same error.
Any ideas? It's driving me mad.
Cheers

With some carriers external codes wont work, so which network is the phone locked to? Contact whoever it is and get it unlocked that way.
Good luck
Hi Duncan, many thanks for your reply. I didn't realise that, I will contact Vodafone in that case. Many thanks.

No worries dude and dont feel you got ripped off, its just some external codes dont work.
Im 99% sure when you buy from the network its locked to (in your case Vodafone) you'll be unlocked and happy days
