First of all i must apologize for not posting on development but im not allowed since this is a new account on xda...I live in London but im in mallorca spain for the summer looking for a job so having a phone is very important. As soon as i got my sgs2 i rooted it .. i was having some issues (random reboots) which led me to think it was either something wrong with the unstable kernel i was using or more likely a bye bye RAM. I decided to reset the phone and installed the LIGHTENING ROM... I Just love it!!! but... now im having trouble with it ... (BIG TIME) I had not realized something was wrong because everything seemed fine until i asked my gf to call me today... she couldnt... then i tried several times myself without success. I rebooted and to my surprise i started receiving a lot of work calls!!! (Which is great) but then i tried calling myself and it didnt work again. Im going back to stock firmware for now since the device is a phone after all. Dont know just yet if this will fix it but ill keep you guys posted... anyone having similar issues??
It might be a small bug in your firmware, try reflashing Stock and then see.. If still the same problem, try stock firmware from another source and reflash.. if still the same problem.. then its a issue.. Post your findings.. please
I have no issue like that.. just trying to help

check if your internet connection is set to wcdma/gsm auto mode...i am having similar problem when it is set to wcdma/gsm auto..it keeps loosing connection and radio switches off...making my phone unreachable most of the time.setting it to gsm only is the only way to cure this at the moment for me.

hi iznee;
I am from malaysia too.
currently I am using stock KE2 ROM. just rooted the phone for some xtra things that I want to do with it.
my phone is set to wcdma/gsm auto connection and never have outgoing/incoming call problem. Data also works as expected and by the way I am subcribed to Celcom unlimited Data plan.
by switching to GSM only, you are limiting the speed ability of the data to GPRS/EDGE only. please noted that you cannot have voice and data simultaneously while in GSM only mode. your Data session will be suspended if you make an outgoing call or if you receive an incoming call.
however, if you set it to WCDMA only, you can have both Data and voice simulataneously and that explain for 3G video call. but, not all areas are covered by 3G thus, if you entering an area without 3G, your phone is useless because there will be no signal.
if you set it to WCDMA/GSM auto, the phone will switch to GSM when there are no 3G signal available and that will ensure smooth phoneoperation in making/receiving call.
After a week of usage, I can confirm to you that I never have outgoing/incoMing call.problem and no data.problem.

morisa

Well so far my findings are null. i flashed kd2 stock with odin with the re-partition parameter on. Nothing happened. Was thinking re-partition would actually get rid of all the apps in case something there was giving problems... the phone was working fine when i was in england with kd1 stock... (How do i get rid of everything and start from scratch?? and what does the efs option do?? im tempted to use it xD) ... One other thing is i read somewhere that kd2 was giving trouble on orange uk (im ukthree but have tried with vodafone spain simcard) any ideas???
Efs is your IMEI code etc.
Backup as per post dev section .

iznee,
I have done a test regarding call in/out and also data connection. below are the test;
I am driving from KL to JB and crossing 5 states (KL, Selangor, N.Sembilan, Melaka and Johor). Along the 400km routes, I have taken the NorthSouth Highway, federal trunk road and also state road. My phone will change from H/3G to E/G when the signal is not available and I've no call drop whatsoever. I made calls while 3G/H signal is strong and also received calls. I did use the google maps.so that the data connection will be.continuous. In 3G/H mode, I can make/receive calls while the maps constantly refreshing based on my driving location.
when I enter the are without 3G, the phone automatically switched to GSM mode. albeit a bit slow.in data.connection, the maps still refresh without fail. when I make an outgoing call, the maps will stop refreshing as this is the behavior of GSM that voice call will take.charge and data will be suspended until I hangup the call then the data automatically resume its connection and the map refresh automatically showing my driving location. Then I use my other phone and call my SGS2 and as expected, the voice call going in and data suspended temporarily.
after hangup, data resume again and the map refresh automatically.
and when 3G signal is available, the phone automatically switch to 3G/H mode again and vice versa along the route.
all in all, I can say that my SGS2 works wonderfully and meets my expectation that phone function is priority. sattelite locks will take no.more than 10s and sometimes just under 2s. Superb performance by the phone.
Camera wise, no complain as I am.not a proffesional photographer. and I am more than happy for the camera performance.
Battery wise, no complain as I have unlimited data so i have all.my Facebook, twitter, push mail, livescore, news, weather etc ON 24hours. anyway, I have vehicle charger with me so the phone will be charged as long as I am driving.
this is from the about of the phone;
Android version: 2.3.3
Baseband: I9100XXKDJ
Kernel: 2.6.35.7-I9100XXWKE2 - CL187606 [email protected] #2
Build number: GINGERBREAD.XWKE2

Sorted!! I made a hard reset... Which led to a bootloop. Fixed turning phone off volume up+home+power . Clear everything and reboot... Voila now works like a charm hope this helps otgers in my situation
Just bought my SGS2 yesterday and flashed it to KI8 and rooted it with CF-Root. Didn't actually test it before flashing but for some reason Google Talk keeps losing connection and signs in very often. Has this got something to do with the modem version losing data connection or is it happening because of some power-save setting?
Today I flashed KI4 and Google Talk has dropped offline a couple of times already. Is my device flawed?
Any suggestions on different modem versions and/or firmwares to try out? Maybe a separate GTalk client?
Has anyone had issues like this? I tried to search the forum but most topics cover connection problems via WiFi and not mobile data.
That happens to me when I don't have a strong connection. I say it's probably a carrier issue.
Then it must be a local issue. My friend has the same phone and same operator, but lives about 150km away from me and his GTalk stays connected.
Is there a way to monitor and/or log the data connection with some software?
I have also run into this problem since rooting. I can't even find google talk on my phone to disable it.

For me it didn't matter if the phone was rooted or not. Wierdest thing is that even if my buddies see me offline, I receive messages immediately when they send one.
Quick update: I found out a way to make signal bars turn green when connected to Google services. Now I can sometimes see that the bars are gray when turning the screen on. So it's clear that my phone disconnects from Google in longer standby.
Hey, as the name says, I'm running Cyanogen 7 on a HTC Desire (Bravo)
when I boot up the device I have signal and a 3G connection, however after a couple of minutes this disappears.
So far I've tried:
- Turning off and on - just disappears after a few minutes
- Plane mode on and off - doesn't do anything
- Flashing the Radio to latest version - no noticeable difference
I go into Settings>Wireless&Networks>Mobile Networks> Network operators and from there is auto searches and doesn't stop auto searching (obviously not finding anything)
I've searched for people with service provider issues but I've found non like mine, hope someone can help! thanks
u might have to reflash rom again..

I've tried that and unfortunately nothings changed.
If this helps: I just tried ringing someone and the signal would go, drop the line after a few seconds and reappear just as quickly. I heard the other person's voice once or twice(I tried phoning a few times) and they claimed to be unable to hear me (as in, no noise at all from my end),
Discovered my problem on the cyanogen forums (can't post link apparently)
Turns out that the 'stable' 7.2 is unstable so backing up to 7.1
So during the last few days I've been unable to make any phone calls, and I don't understand what's actually wrong. There's nothing wrong with either the microphone nor the speakers, as they work in other apps. The problem is that I don't hear other people and they don't hear me I don't appear to have connection problems either since other apps work as usual, with or without wifi. I'm running the Concept 4.0 rom.
It's possible that it might be some sort of water damage because I dropped it in snow the other day but that seems unlikely.
So far I've tried:
-wiping and re-installing the rom
-wiping and installing the Poison rom
-formatting and re-installing
-tried installing without fast dormancy
-restoring back to old backups, where there was no problem, using TWRP
-I tried my SIM-card on an older smartphone and there was no problem.
So does it seem like some sort of hardware failure or some software bug?
Edit: As of now, the phone works however, I've yet to discover why it didn't work in the first place. If you know anything I'm still interested.
Edit 2: So it's been nearly a month since I posted and I'm writing this because I want other people who might have the same problem to be able to fix it. The problem with alot of the roms for the F5121 is that they lack options for controlling exactly which networks to operate on. The fix for this is to enter the "hidden" menus by entering *#*#4636#*#* in the dialer, from there you can fine tune alot of the settings.
On Mobile network settings > Prefered network type.
If you force LTE only and go to a location with no LTE, you won't be able to call also people won't be able to call you.
Hello guys, I'm having a huge issue with my mobile network.
For the past two weeks I've not been able to make use of my mobile network correctly, it sometimes works, but most of the time doesn't. The icon in my status bar shows there is activity, it's fully connected to 3G or LTE, even with full bars. But all my apps like Telegram, Pokémon go, Messenger and the likes are stuck "reconnecting" to the network, as if my phone doesn't have any reception at all. At some points even SMS messages refuse to send, even though I've got full reception.
I've already gotten my SIM card switched out, attempted multiple clean flashes and the issue still persists.
Phone: Oneplus One
My current firmware: 0.1.c1.11-00006-M8974AAAAANAZM-1
Current ROM: idprophecy's unofficial optimized lineage-14.1-20180413-UNOFFICIAL-bacon
Current Recovery: Kutep0v TWRP 3.2.1-K2
Is there anything I can do? I'm getting really desperate.
This is my last plead on this forum, as I haven't had any response from anyone since april 25th, I've got nothing else to do but wait. Can't find anything on the internet about this issue, you're my last hope.
Have you tried flashing to stock version?
