Try typing *#*#4636#*#* in the dialer, you might have some luck toggling those options.

Can't restore settings or app data in CM 13 or 12.1

Hi.
I managed to root my T-Mobile G900T
I put Vision-X on it and got all my settings and data back, no problem. Then I decided I wanted to try something different, and loaded up CM 13. It worked fine, but I couldn't restore my data and settings. I tried CM 12.1 and had the same problem. When I use TWRP and try to restore data I get caught in and endless boot loop. I cannot get any of the app backup apps to work, and Titanium won't even recognize my SD card.
Any ideas?

[Problem][Solved] No signal out of nowhere

Hey everyone,
I have a new problem with my moto x play on XDRom.
Out of reason, my moto x play stopped having signals.
I tried to remove and reinsert SIM card but nothing happened.
I think it started when I removed GhostCommander and Hacker Keyboard apk in /system/apps and priv-apps.
Is it possible that removing them cause the booting to stop somewhere?
Thanks for every possible track we can find!
EDIT: If I go on SIM Cards in Settings it shows me SIM Slot 1 SIM1 - XXXXXXXXXXX (which is my phone number) so I guess my sim card is recognize..
Solution: For anyone if it happens, my cell kinda unregistered from my carrier network so I had to reconnect to it. But now I'm having disconnections.
Edit: In fact it is stuck into 2G network but my carrier support only 3G and LTE so I can connect to it if I changed that but it is changed back to 2G after 2-3 minutes
Cordially,
Baskwo
Looks like your tinkering broke something mate! If your signal was working before then you can re-flash your ROM as if you never touched system and also retain your data.
1. Reboot into recovery (e.g. twrp)
2. Wipe system
3. Install the ROM and associated zips
4. Wipe cache and dalvik cache
5. Reboot and wait
Should be like new with whatever installed apps you had. Also I recommend using System app remover from play store as it removes what you want for you without getting your hands dirty if you like.
Leave a thanks if I helped

Android O on Fi not seeing SIM Card

I downloaded the O factory image for 6p. I made a nandroid backup of 7.1 and went to work. Upon boot it will prompt to install SIM card. It works fine on custom 7.1 ROM. I ejected the SIM tray pushed it back in still would not pick it up. Rebooted to recovery cleared davlik art and cache. Rebooted back to setup and again it asks for SIM to be inserted. Rolled back to 7.1 nandroid and no problems.
Anyone on Fi running into this problem and a way around it?

Hello, I receive this problem.
Before making my way, please, make a backup of all internal storage.
For resolving this issue, needs to go to the Settings > System > Reset >
1. Had have reset the Network Settings
2. And had reset factory data
This has helped me.

I'll try a complete wipe again. I also tried the 2 ROMs that are 8.0 based and same thing there.
:Edit
I had to use TWRP and wipe everything before it would pickup the SIM on factory image. Now trying O Roms and see if same result. Before I'd just use standard wipe and would boot but not see the SIM card every time.

I had the same issue when going from 6.x to 7.x.
I had to completely wipe the phone and install.
Anything else and my phone would fail to see the SIM and BT would not work.

UI crashs when mobile data is activated

Hardware: SM-G900F (klte/Galaxy S5)
ROM: Unofficial Resurrection Remix
Hello,
I used this custom ROM for several months and suddenly, a few seconds after activating the mobile data the system UI (note the complete phone!) crashs, restarts and crashs again. I only could break out the loop by disabling the mobile data. Wifi and calls are working without problems. Sometimes it shows "no SIM card" under the icon of mobile data after the restart, but it crahs again.
First I thought it's a hardware error, but after reset of system data it works also with mobile data. When I restore my backup, the error came back.
I would simply reset my system data and everything is fine, but then all my data will be lost. For transfering data to this phone I used Titanium Backup and it works, but since this error occurs, Titanium Backup crashs also.
Does somebody have an idea what I can do to solve this problem without loosing my data? Thanks
Same problem here !
The only option is completely wipe the phone and install everything again (which is really annoying).
I used matlog to get a logfile if someone want to investigate this.

Having problems with sim cards after updating to android 10

I recently updated to 10.3.1 from android 9 i was rooted using magisk and edxposed installed so after installing i didn't reboot i went to magisk manager and installed to other slot and rebooted.
Everything's fine but both sim shows emergency calls only so i downloaded offline package and installed it locally. Root is removed and both Sim are working fine but when i go to settings and open Sim & network it says com.android.phone keeps stopping.
I'm unable to send messages and check balance using ussd code. I don't know what to do.
