G870A after cert write and QCN fix shows E for mobile data.

Any suggestions? I had another G870A that worked fiine with the same exact process. All I did again was write the new cert and write the QCN fix. When testing the phone it takes a very long time to register with network but then only show E and no data connectivity.

Any suggestions on fixing the radio to not show E (2g) only? after cert write was done

Hello.

Please check whether correct option is selected in "Network Mode" menu. Try to write another Cert file. IMEI of Cert file, which You've used might be in "black" list of Network provider.
Read out QCN from another, correctly working SM-G870A and try to write it into your phone.

Hi I am still having the same issue, now with two different G870A phones. The cert is not black list in black list check. What do u mean by Network Mode. What option do I need to correct?

You need to select "Auto", or LTE/3G/GSM mode in phone's Settings.

Have You tried to write a QCN file from another SM-G870A, which works correctly in your region? What was the result?
