"no networks found" problem.

hi.

I purchased a fire phone (AT & T unlocked) through eBay.

And I used normally four hours through a firmware update for 4.6.1 (including call and data)

But, unfortunately, as an update to the firmware of ..4.6.4 not normally use (the mobile network itself unusable state.)

Although recognized as a problem of the first firmware and carried by the downgrade version 4.6.3 through the ADB, the problem has not been solved.
Even then downgrade to 4.6.1 version is still not available.

I check the logs through*";dm" command, was able to confirm that awful crash logs are generated.

Is there any way to initialize the fire phone through the adb?
(Factory reset the recovery mode does not help at all.)

Does one have experienced solve this problem?
Current and using a carrier KT in Korea, and another fire phone is seen to be operating normally, USIM is normally available.

The first mobile network operating normally seen as something that seems to be a twist in the firmware update process internally with fire phone.

In summary, the present problem as follows.

1. Normal operation after first being released in the 4.6.1 firmware.
2. 4.6.4. After the firmware Firmware Update is disabled (mobile network unavailable)
3. 4.6.1 firmware downgrade - Mobile network still impossible
4. Select Networks Operator - no networks found

How to edit saved WiFi Networks on S6?

I can't seem to find my saved WiFi networks when I'm not around them. I believe before there was an option for that in Android. I would like to delete some of the WiFi networks I connected to before. Where can I find the list of remembered WiFi networks on S6 G920F?

WiFi search shows up no networks

has anyone else run into this issue? my wifi seems to be on the fritz. a week ago i could search and add new wifi networks just fine. however, recently my wifi only connects to previously saved networks. when doing a search, it shows up completely blank. what's peculiar is that when i downloaded "wifi analyzer" from the play store, and did a search, i can see the wifi networks all perfectly fine. it's just the wifi search within settings shows up NOTHING.

Lg G3 850d networks

Hi, I recently bought a LG g3 smarthphone and I found out that it's an AT&T version phone, but thankfully it's unlocked. My problem is, that it doesn't get any mobile network. In the setting it says that the Mobile network type this device can use is EDGE, but my local carriers can only provide LTE, GSM and WCDMA. I've tried to solve this on my own, but without luck. The solutions with 3845#*850# or similar codes just woun't work, when I choose any RAT it says: "succsess", but it doesn't change a thing and when I choose LTE only mode the phone blocks my mobile connection and says: "Restricted access changed: Data service is blocked" .
I really need any help, because I cannot see myself using a mobile phone without mobile internet. BTW, my location is Estonia.

[REPAIR][ROM]LG Official Kitkat 4.4.2[stock] Fix 2G Only / Mobile networks settings

For those of you who activated 2G-only mode in your Mobile Network Settings and can't use that menu anymore due to crashes, there is a relatively easy way to reverse this condition and bring back the menu functionality while untoggling 2G-only mode.

1. Make sure your ROM is rooted (should be the default state of Paulicat's ROM).
2. Use ESFileExplorer (or a similar root capable file manager) to backup the contents of the following directory:
/data/data/com.android.providers.settings/databases/...
(Note that the critical file to backup is 'settings.db', the journal and other files are not critical but should be copied just in case)
3. Make a copy of 'settings.db' in a temporary location
(You will edit this copy of the database)
4. Use an SQLite editor (I used SQLite Debug) to open the 'settings.db' file you copied previously
5. Open the 'global' table and find (by the 'name' column) the row with 'name' that is 'preferred_network_mode'
6. Update the 'value' of this row from '1' to '0'
7. Execute your transaction and commit the changes to the table
8. Close the db and re-open it to verify that your changes have persisted
9. Return to '/data/data/com.android.providers.settings/databases/...' and delete the entire content of that directory
10. Immediately copy and paste the edited 'settings.db' file into the '.../databases/...' directory
11. Immediately turn off and restart your phone

At this point, you should have changed your phone's network preference setting from 2G only back to 2G/3G. This will also allow you to access the Mobile networks settings menu again.

I didn't find this solution for months because I didn't realize that the Android global settings database was stored in the above directory. I hope posting this here might help someone.
