Here's something interesting:
I have been using this ROM as my primary for weeks now. I have had solid 3G service the whole time.
To get 3G to work, I usually dial *#*#4636#*#* and switch it to either GSM auto (PRL) or GSM/CDMA auto (PRL).
Like I said, I've had ZERO issues attaining and retaining a data connection.
Now here's the problem I'm encountering. For the first time since switching to this ROM, I went into a 4G area. I was in the 4G area running on 3G with no issues for about 8 hours. While still in the 4G area, my data dropped. From that point on, I have been unable to get the data/signal to work correctly.
If I use either of the GSM auto (PRL) or GSM/CDMA auto (PRL) option, I get zero signal bars and have no connectivity at all (be it for phone calls or data connectivity). If manually change through settings the connection type from LTE & CDMA to ONLY CDMA, and then via the *#*#4636#*#* menu I choose CDMA only, I get signal bars and am able to make phone calls and sometimes get a 1x data connection.
Here is what I've noticed - since my signal drop in the 4G area, whenever I choose either of the GSM auto (PRL) or GSM/CDMA auto (PRL) options, in the *#*#4636#*#* menu, the row "Network type" reads "LTE:14."
I believe this is where my issues lies. Before having ventured into a 4G area, LTE was never listed there. I believe that something has been changed somewhere so that the phone now looks for LTE.
To try and resolve the issues, I've hard reset my safe system ROM multiple times, I've restored a backup from days prior to the the 4G adventure. I've cleared the Dalvik cache as well as the normal cache. No matter what, I'm unable to get 3G working again.
Is there a way to completely wipe what's on the safe system to start from scratch?
Any ideas!?
