Mobile data not getting connected. PLEASE HELP! - Android Q&A, Help & Troubleshooting

Hi,
I recently upgraded my Lenovo A6000 phone from stock to RR. Mobile data gets disconnected after sometimes. Same happens for RR in my Moto X pure. I have to restart the phone in order to get the data back ON or sometimes aeroplane mode works. In *#*4636#*#* hidden menu, the data connection status showing is "connecting" rather than "connected". Signal strength is good. Tried resetting APNs, Dalvik/Cache reset, and nothing works. The network still gets to "connecting" mode at random times. Any solution to this? Any way to debug this? I'm fed up with restarting the phone. :crying:
Any advice or suggestions will be greatly appreciated.

May flashing modem files of your android fix the problem.

May i know what it does? I saw some image files inside the flash-able zip resembling modem files and other files. Ain't those specific for different makes?

The solution to this problem is the corrupted kernel. Flash the rom once again and then flash a kernel. This should fix the error.

You are a life saver. I was scared to work with kernel files. First few tries failed after playing with modem, modemst1, st2. Had kept backup. In the end putting back fsg file did the trick. LTE is stable now in my Lenovo A6000.
Waiting for VoLTE patch for Moto X Pure xt1572 (For Jio of course). Will fix it after that and update you guys. Thank you

[Q] [HELP] GPS auto on at P780

as subject last few weeks ago I've got this issue, previous months it was working fine.
when my mobile data ON (SIM1), GPS auto ON, tried many times to turn it OFF it keeps back to ON after few minutes.
It's annoying since its drain my battery. Suspect it is related to google location sharing, so I turn it off all location sharing then its back to on again and again. But it is no issue when I turn off mobile data at SIM1 (3G) and connect via wifi also no same symptom when I moved simcard to SIM2 (2G) and using mobile data.
So, first what I did is do factory reset and do ROM refresh trough maintenance mode -- > no luck
downgrade ROM from 124 > 119, factory reset, formating internal and external storage, and do ROM refresh trough maintenance mode --> no luck either.
at this point im hopeless and thinking to move to previous brand which is run more stable. So, any guide or help it will be very welcome before I throw this lenovo :crying:
thanks.

I have a question. Did you try to change your SIM card with a new one or to change your GSM network something like Orange with Vodafone?
Sent from my Lenovo P780 using LiFe v.07 and TWRP 2.6.3.0.
Hi,
I too experienced the same GPS auto on problem. It all started about 2 weeks ago and sucked the battery a lot.
I tried to downgrade my ROW 8GB S124 to S119 original rom, same problem persist, then I tried S123 rom same thing, and now I am back to S124 rom nothing solved. I did wipe the cache, Dalvik, data and andriod secure during each upgrade / downgrade, and also format storage and reset from Android system. Also tried custom rom, not successful in solving the gps problem.
Really haedache with this problem, does it mean that my phone has hardware problem ? Or I have to change another sim card into slot 1 to see if it reproduce the same issue ?
GPS Auto on problem
Hi - I have the same problem. I 'm using Lenovo P780_ROW_S116_130828 ROM. I've noticed that the problem appears only on local roaming. My network enables local roaming on T-mobile. Only then it switches on GPS. As if it was launched by the APN? I've tried to switch off all services with location/fused location/geotagging etc. no luck. Problem disappeared only when it is unable to dial (to many services switched off). If it dials thru t-mobile - GPS launches. On standard network - or other providers everything is ok. Changing modem img to v52 - also no luck. What I know is that whenever I turn off Allow Network Initiated Request in Mobile Uncle Tools (AGPS settings in dev mode) it reappears switched on. Maybe it is the problem?

A temporary remedy for No Service/Loss of Network Signal on AOSP 5.1

Hey there guys! So, I know everybody might be suffering the same fate as I have on 5.1. Signal Loss when rebooting the phone. Well, I might have found a remedy for that and here's how you do it:
When you loose signal, don't go and do multiple restarts on your phone. Instead, activate Airplane mode first and then do a reboot. When your phone has booted, turn off Airplane mode, wait for a couple seconds and Wallah! Your Network signal is back.

I had this issue when I flashed ROM with CWM (R7) version.
Later I flashed with CWM (R11) and it fixed this network issue.
wow...it worked for me...thanks @Jhayzt
Nice ... thanks i gonna try this . At times restarting again and again becomes irritating.

Lag after wifi disconnects in CM13

Hello guys!
I'm having problems with my s3, whenever he disconnects alone from the wifi network he causes lag on his cell phone, sometimes he even reboots himself, could anyone help me?
My device:
S3 (i9300)
CM13 with Boeffla Kernel updated
What exactly type of lag it is? Have You tried doing a factory reset?

The device hangs in the application and keeps locking until the wifi reconnect again alone, while not reconnecting the device becomes unusable, sometimes causes reboot of the system .. I tried factory reset already ..
sorry for the bad English

It happens only in this ROM or in every? Is it the latest cm13? It could be the fault of the system. Try reflashing it.
Only in CM13, I have reflash sometimes, yes, the last snapshot
Have you tried manual network settings?.
Does the SSID have any spaces or "other" characters that are not 0-9, A-Z?.
Make sure your wifi IP address is unique to your device.

1.yes
2. no
3. my wifi ip is unique
You're best flashing back to stock and starting over. Flash to stock, factory reset and flash the stock rom again. That way all traces of old will be removed.

I solved the problem, the update 20161220 is much better, and i've tried to fix the wifi connection, thank for all!

Not registered on network

Good day guys.
I have a problem that I think is very common, however I haven't found a solution yet. I recently update my S6 edge (925I - latam) via odin to Nougat, everything was cool but I can't do or receive both calls or sms. I have cellular signal, however there is not registered with the network carrier.
I already flash modem.bin from older firmwares and do not work. Sometimes I loose cellular connection or stay the same, with signal but not registered. I tried other possible solutions like airplane mode and reboot, flashing roms, connect only via 2G or 3G, nothing have worked. My sim is not corrupted and the imei is just fine, without report or related.
I hope you can help me. Thank you very much.

Same issue for me.
Tried:
OTA update
Odin update - installing new stock firmware (with different software version)
Factory reset
Installing TWRP + LinageOS beta
Replacing the sim slot in a service
Nothing worked. Anybody?
Look in settings > status
Do you guys have an IMEI?
This happend to me 2-3 times last 30 days... sometimes I have signal but not registred on network, sometimes there's even no signal, etc...
I also tried several things to resolve the problem...flashing modem, reset dialer, changing network mode, enabling airpalne mode, another SIM card, etc... For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

Bro, download some older firmware from the one you have from sammobile and exctract it...there you'll find modem.bin
At last, I couldn't fix my s6...so I sold it...then the guy who bought it needed to write some chip to motherboard and he got it working again...
