The fact that it sometimes works excludes a lot of things. APN is fine, I checked it and it wouldn't work at all otherwise. Could it be that I messed something up when I flashed it with KK rom?
What could I do to fix it?
I'll try unrooting it and returning to stock to see if it will fix it, but I have my doubts....
Do you have any suggestions? All I want is my data connections working reliably again, device rooted or not...
I have reverted my phone to stock. It's the same as it was when I got it, except for thw KNOX and warranty part. Since my warranty is void anyway, it's really a shame to use stock rom with all the crapware on it.
Do you have any ideas that would cause mobile data to work on stock, but not on any other rom?
