Hi All,
I have been using this CM9 KANG since it first started from this thread: http://forum.xda-developers.com/showthread.php?t=1461240
All has been fine until this morning when i couldn't connect to 3G. This has happened once or twice before, but a reboot fixed my connection problem.
Things i have tried so far:
- Reboot (several times)
- Wiped data and cache
- Tried a different SIM card
- Tried original SIM card in my work-issued Blackberry (all worked fine)
- Gone back to previous recoveries that worked fine before
I can deduce that it's not my mobile operator. I am unfortunately not able to try a different service provider at this point.
Can anybody please suggest something that i might have missed?
We do not have a fully/widely developed wi-fi infrastructure in South Africa, so i rely heavily on my 3G.
Your assistance would be highly appreciated.
APN settings?
I used Ultima rom v12 JB 4.1.2 for a long time and switched to CM10.2 4.3.1 recently... Since then, i am losing my mobile data a lot... I flashed efs v2 modems (MH1) also but it didn't solve the problem. Today, after doing a full wipe thru CWM, i flashed the sammy leaked official MJ9 thru odin but didnt solve the issue.
The data speed is good when it is there. It gets disconnected after varying intervals of time. It gets connected back on its own but after an unpredictable time.
I switch on/off the mobile data, wifi and airplane mode, edit the apn name and save it, dial a number and terminate the call and remove the battery and put it back... All these don't work. The data will come back on its own accord!!
I'm really frustrated!! Please help me in any way possible.

Mobile Data was working okay until CM11 M2 then I updated to M3 through Settings with the CM Updater
and I cant get Mobile Data anymore since then I tried M4,M5,M6 and now M7 and nothing changed (all were clean installs)
I also tried flashing a stock rom still no mobile data. I did reset APN settings also tried manually entering them got nothing.
if you need screenshots or any more info to help me solve the problem just ask
Is it just the mobile data gone or is it that your signals are gone too? Sometimes it shows full signal strength but with mobile data gone you can't even make a call.
When I had this problem, my imei and baseband were screwed. Check that too once.
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?
Hello, i'm flashed a new rom
[ROM] Dirty Unicorns 4.4.4 [UNOFFICIAL][BUILT-1](16-8-2014)
And don't have any problems. Currently in home i connecting to linksys, wifi mode is N. I visiting my mom it has router d-link 610, i suppose it has G wireless mode, so the question is following, when i scan any wifi connection, i cannot see her router, however all other devices perfectly see, Note 3, notebook with N mode. And i cannot understand why it's happening, may i should reflash "some" module, so it started to work.
It's currently blank, even if i put manualy SSID and password.

Thank you for answer, after some experiments i flashed bad rom (don't ask my how about 2 years of experience), hopefully fastboot still worked, i reflashed nemesis kernel, and after it , throught adb iterface i pulled to phone corrected rom. However, i decided to return to stock rom with flashtool, after all long time of manipulation of my xperia (about 1 year),
And now it's working almost great, however i'm still finding a good rom.
Also i did as you adviced me, still no results. By the way thank you
