About two months ago I flashed g00h's first TW lollipop rom. In order to do that, I updated my pda and csc to NL8. My bootloader and baseband are NK3.
On touchwiz roms, I have no problem whatsoever; however, as soon as I flash an aosp rom such as Temasek's cm12 or the new pacman rom, I start to have problems related to my service and wifi. when I have wifi turned on, every now and then I'll lose service for a minute or two. Wifi continues to work, I just have no phone coverage.
Why?? I've done some searching, but the only similar thing to this seems to deal with wifi calling-this has nothing to do with wifi calling since this is an aosp rom. Additionally, my service and wifi work perfectly fine in TW roms.
If I updated all of my firmware, would that solve my problems, or just create new problems?
Thanks for any help.
Edit: I think I've fixed the issue by updating my baseband to FOB6; since updating, i haven't noticed losing service yet.
So if anyone has this same issue and finds this thread, update your baseband to FOB6.

Hello everyone, I've seen some other threads about similar signal loss issues or problems on the i927 around xda, but none of them worked or were compatible with the type of problem I'm having. I recently installed the January 6, 2013 build of Paranoid Android v2.+ on my i927, and it works great. However, I've been having one major issue that renders my phone useless. After about an hour or so of having the phone on, I lose ALL signal to my cell network (AT&T). There are no signal bars, no messages/MMS/calls can be made or sent, and I end up having to reboot my phone for it to function properly again for another hour or two.
I've tried what some users around xda have suggested such as taping my SIM card in place or wiping cache/dalvik cache in recovery, but as of yet nothing has worked
If anyone can help me, it would be GREATLY appreciated. I'm stumped at this point after exhausting all the options I thought would work. I really want to keep this ROM on my phone, it works better than stock or any other ROM I've tried yet by far.
Thanks in advance!

ALSO, I can post screenshots or any additional information if it's helpful in any way.
How did you unlock? I've had problems with signal when I unlocked via galaxsim unlock tool. Check your /efs/Nv.log for errors, I had an error connected with md5 sum every second or so.
For me, the other unlock way solved all the problems.
can you see in about, your imei, maybe is corrupt. see this link, maybe help http://forum.xda-developers.com/showthread.php?t=2019540
I haven't unlocked my phone, it was sold to me as an AT&T phone. I don't think my IMEI should be the problem

I also experienced this issue on 4.1.2, so I moved to 4.2.1 hoping to avoid it, yet this morning issue happened again with thegreatergood's i927 - CM10.1 - 1/22/2013. My IMEI is ok, unlocked by entering the unlock code given to me by ATT.
Note I am able to restore connection by switching on and off airplane mode, might save the time of reboot.

Yeah, I've tried every now and then to reset my connection by toggling airplane mode on/off, and it usually works for me too. I'm just stumped on why there's an issue with the signal at all to begin with, it doesn't make sense to me
I confirm, I also experience connection lost from time to time. And I also restore it with switching airplane mod on/off.
The same problem with 4.2.1
Hi! I had the same problem with the phone. The signal was totally off. I was using LiquidSmoth 4.2.1. I gave a solution flashing the rom another time.
I've seen this on AT&T's ICS firmware, it gave me this issue often and for me a reboot was the only fix.
I've upgraded to CM 10.1 and I am hoping it fixed the problem. If not, I will try flipping airplane mode off and on, I don't like battery out reboots, but if it doesn't any more suggestions welcome.
Thanks.

I've been using cm10.1 for months now & haven't had any issue with signal dropping. Did have if happen with other roms, but I think it's something to do with the kernel more than the rom. They just released rc1 of cm10.1 has the latest kickass kernel.
my device now: i9195, I9195XXUCNE6-DBT
I experience weak signal and many connection dropdowns. When this occured first, after i upgraded f4ktion Kernel 1.3.6 to 1.4.5 and
an older version of Carbon Rom (4.2.2) to 4.3 Carbon Rom. Until than everything was fine, flash of rom and kernel did not made any problem.
Btw i used Odin3 3.09 and clean install (step by step like in the guides) all the time.
After some days this realy annoyed me, so i went back to the older Carbon and kernel - problem still occurs.
So i went back to stock rom I9195XXUBML4-DBT (original was UBML4) - problem still existing.
Some time later f4ktion 1.5 and Carbon 4.4.4 was available, so i tried this..still no solution.
Now i am back to stock and updated to I9195XXUCNE6-DBT, same problem.
Some research told me many ne stuff to know..like flashing modem only. I tried some, nothing helped.
After hours of pointless googleing i noticed something on my phone.When i dont type the pin, i have normal signal. As soon as i type the pin
and "activate" my simcard, the signal strength drops. So i googled again and found this:
[Bug Watch] Android 4.3 Radio Bugs Causing Cell Connection Drops On Some Nexus 4 Handsets, Fixes In Sight (not allowed to post links)
I changed the network type to WCDMA only - it helped for some minutes(not many..maybe 2-3). I changed to GSM only and i had normal,
stable signal for like an hour. But later signal loses strenght again, and i need to change network type again.
I have the feeling, that its like a reset or restart of the radio.
But now i am all out of ideas and need some help.
Last thing i can do, is to bring it to repair. But my Knox says 0x1, so maybe you can help me before i ask Samsung.
I have similar problem since ugrading to KitKat roms. I had no problems with previous none Knox roms with MH3 modem but now with NE6 and NF7 KK modems the signal swings constantly up and down from 4 to 1 bars. This is in areas I previously had good signal. Internet also keeps dropping out requiring data toggling on and off. I've reflashed KK 20+ times and haven't been able to get rid of this problem yet.
I'm not sure if pre knox modems are installable but I intend to try and reflash MH3 modem, once I manage to do a successful backup.
I solved a similar problem by downgrade to 4.2.2 Brazil NE2, knox 2. Flashing separate modem (NE2), and reflashing full rom again. No problems for now
Now you stay on 4.2.2 ?
I dont understand why some people do have problems and some not. Is there different hardware version causing the trouble ?
Give me pls some information how you did the downgrade.
-Nandroid Backup
-philz
-Odin (if yes which version)
-why did you choose that rom
I tried to, but wasnt succesfull. I used Odin3 3.09 to flash 4.2.2 (UAMF5 i think) rom and got a brick. When trying to fix this nothing helped until i tried to flash with Odin3 3.04. But all i could do was flashing newest FW again. Did not test more after that, because i was very busy.
If you say that going back solved your problem, i will try again go go back myself. I've found some information on that and when its done i give some informations.
Same here, help?
I'm having the same problem with a newly acquired handset. I have full signal on some places and nothing on others, unfortunately in my house I have no signal! So it's quite exasperating.
My baseband version is I9195XXUCNE6
Android version is 5.0.2 with 3.4.0-cyanogenmod-g92aec50 [email protected] #1 kernel
Cyanogenmod version is 12-20150306-UNOFFICIAL-serranoltexx
Would it help if I flash a separate modem file through Odin? In that case, which one should I flash?
Any help would be appreciated a lot.
Thanks

If you have warrenty left then you should go to customer service then they will change your mainboard. and it would bw okay.
Hi everyone, I'm having an issue with intermittent data drops, I am using an SGH-I747, that is rooted with CF-AutoRoot, with TWRP and CM 12.1 update from 4/28 installed (recently updated to the 8/22 nightly). I have the I747UCUEMJB modem installed and. My carrier is T-Mobile and I have a a SIM card installed that is only 4 months old, of course T-Mobile support won't even discuss anything with me other than "if you purchase a phone from us you shouldn't have this issue". Give me a break T-Mobile, lol. I am in the Tampa, FL area so I doubt it's a coverage issue, though not out of the question.
I have been getting several times a day where my cell connection completely drops out and the DBM drops to zero, when this occurs it lasts for about 10-20 seconds and on occasion I have to reboot the phone. I switch my data off when I'm not using it and this issue tends to occur about 3 minutes give or take after switching it back on, also it's more frequent when I'm using mobile data for apps. Other times whether or not I'm using mobile data or not I periodically get issues with text messaging where a text just "spins" and eventually fails to send, only rebooting fixes it, this happens at least once a day.
If I attempt to "search for networks" to try regain LTE it never is able to successfully find networks, I can only choose from a slew of what seems to be pre-installed ones ( the T-Mobile ipv6 or regular T-Mobile choice has been working ok). If I enter an unlock code I get a message saying "operation failed". Aside from this, I love this phone and this ROM.
Any Ideas folks?
Thanks.
You may be faced with having to update your bootloader and modem to at least NE4 to get the phone to work consistently with CM12.1, or any LP ROM. If you update to NE4 you may want to go all of the way, NE4 to NJ1 to NJ2.
Hi there, thanks for the response. I think it's a JB bootloader and radio I'm running on this, I've searched several threads and so far the only ones I can find is the ones I have currently loaded or older ones. Do you happen to know where I could download the NE4, NJ1, or NJ2 from off hand?
Thanks again for the help.

i am with ringplus. today, suddenly i lost my cell network. can not make calls, other phones on ringplus seems to be ok.
so, now i need to flash a TW rom to update prl and profile. I saw the SwamMonster v3.0. downloading now. i suppose its KK. anyone know what must i do to downgrade from 5.1.1 to 4.4? thanks.
I'm on boost and lost all cell service when I flashed a backup I had. I just flashed the latest stock rooted we have and it's back up just fine.
it seems like a ringplus issue. been fix for a days. hope it will stick. thanks all
i used only stock roms since months. two weeks ago i tried cm14 for one day but went back to imperium. i do not know exactly when my problems start, but i think it came with flashing cm and empirium backwards. so the problem is, that i have only slow internet connection (edge) until i reboot my phone. after the restart 4g works again. after i loose connection it only connects with edge again.
i tried any available rom, kernel and modem, but all have the same problem for me. i think the original stock v20d seems good (flashable zip from xda, cause i have no windows for kdz flashing).
Somebody know what to do? I dont think it is hardware related, because after a reboot it works....
