Try changing the modem to the one you originally had (assuming your phone's mobile network did work before).

I had the same thing happen with my wife's phone, posted a thread in Q&A
http://forum.xda-developers.com/showthread.php?t=1338170
Turned out that flashing the CWM KJ6 modem was causing the phone to not see the SIM card. Not sure if you are having the same issue. Reflashing Valhalla 1.3.2 resulted in everything reappearing and the phones been fine since. Check your mobile networks tab under Wireless and Settings. If it tells you to insert a SIM card to log on to available networks (you already have your SIM card inserted) then reflash the GB ROM and don't mess with the modem - that should fix it.
EDIT: Once I lost the SIM it didn't matter which modem I flashed it wouldn't come back. Reflashing the whole ROM did the job though.
ALright thank you for the info i am going to try this right now
now while trying to install the GB again in ODIN im gettin a fail.
now i have the firmware upgrade fail screen.
I read this is still fine for installing GB on ODIN , so i tried again. Still getting fail. i read that you can remove your sd and sim card and it should work. still getting fail!
can anyone help !
im folling the instructions to a T.
Hit PDA add the zImage-root.tar file
getting fail

alright i got it now, turns out the zimage-root file was corrupted.
Im using a mac and transfering the files to a old window laptop without internet connection =p

[Q] stuck roaming after flashing

i flashed the new cyanogen mod stable 10.1.0.1-d2vzw and now my phone is stuck roaming. I have tried flashing back to stock and even got a new sim card and activated it still nothing any ideas?
welcome to the party
after doing research, i have seen most people are able to get service by odining back to stock then dialing the factory reset number...however, you will be stuck in roaming service
to fix that i'm yet to confirm...
one solution i have read about is using adb and doing an nvreboot as the nv ram is corrupt (probalby showing 0 for imei, none for eri, and zero's for meid)
another possible solution is using this tool

[Q] Phone keeps rebooting on latest CM12 nightly.

Hey guys I have a very annoying problem and I was wondering if anyone could help me. I flashed the latest CM12 Nightly (8th March) today using Cyandelta but since i flashed and rebooted my phone stays on for barely 10 seconds before rebooting again and this is a cycle that my phone has ben going through for the last 2 hours. I tried wiping the cache and Dalvik but the problem is still there, I turned off all connections on my phone (put it in airplane mode) and it still reboots. Any help would be greatly appreciated because there's this girl I was having a really good conversation with but can't now because my phone refuses to stay alive.
Have you tried clean flashing yet? That should be the first thing to do before creating a thread.

Same problem here
I have the same problem after clean instal on the same build after changing my theme. that's realy strange.
edit: I have reinstalled the latest cm build again (clean instal with google apps) and then I switched a theme againe and the first time it worked this time and it rebooted once after changing (that's new I think) and than I rechanged tha theme and it rebooted againe and than it keeps rebooting (it's not a bootloop because it boot up and than always soft reboot again) so it is definitly a bug in the theme engine of the last (20150308 build) I think.

the only fix is to instal back the previus build (20150304) and the theme engine works again and also it don't reboot your'e android if you change a theme.
Not happening to me.
I dirty flashed 3/8 over 3/4. I also flashed latest Xposed zip build (3/8 also), wiped cache and dalvik cache, and everything is working fine.

I have same problem, I think
Hi,
I have a Oneplus One that keeps rebooting, it only goes to the home screen for 2 to 3 seconds and then reboots again, so....I am at a loss for what to do. I sent a ticket into to oneplus. I have never done anything to the phone since opening the box, I have only let it do it´s automatic updates when they became available, I don´t even know which cyanogen update it´s on. (bought it July 2014).
P.S I have been reading terms such as "rooted", dirty flash, flash, ect...I have no idea what these things mean so if anyone helps me, you will have to explain step by step. I guess you can call me a "cellphone dummy".
Thanks in advance
On my Samsung GT-I9100, CM12 will reboot when I wake the phone from a lock screen. So I delayed the Sleep to 30min. Not a permanent solution but it gives me time to figure out something to solve the issue once for all.

Phone keeps rebooting after odin PC3

I even restored my backup, it boots fine then after 30sec it reboots again and again.
Same here idk whats messing up our phones
Well wsup does it still do it.

One thing i did with out mentioning before i got it fixed. I pulled the sim a few times

Lineage OS - problem with wifi and HDR.

Hello everyone.
I have 2 problems with LineageOS on Oneplus One.
First HDR does not work properly. I can not do a photo with HDR enabled.
My another problem is with WIFI. Many times I have lost connection to internet without report, and I must reconnect manually. My phone is connected to router but without internet. It is very annoying problem for me.
I fashed:
lineage-14.1-20170206-nightly-bullhead-signed.zip,
Gapps Android 7.1/Lineage os ARM Pico ( other did not work because of low free space of disk. I have 50 gb free. Weird )
Latest Super Su.zip
I flashed them all at once. Was it good idea? Or I should flash them separately ?
Of course I did clean wipe before installation and Wipe Dalvik,cache after installation.
Thanks for replies
Same issue with the Wifi here
Well, I flashed again system, gapps (pico) and root but now in sequences.
- flashed room (after wiped dalvik/cache)
- reboot to recovery
- flashed Gapps ( after wiped dalvik/cache)
- reboot to recovery
- start phone
- reboot to recovery
- install root
Now everything works fine Even wifi so problem is solved.
Maybe someone will solve his problem by my guide.
That didn't work for me.
Anyone with another idea?
The "heartbeat fixer for gcm" app seems to be doing the trick for me.
For hdr; go to play store and download cyan apps app and go inside, download camera(basicly it updates the camera app to the latest version and hdr will be fine)
For wifi; i have whole topic about it. This problem happens rr remix tugapower and lineage(those 3 are the only ones i tried so i dont know if it happens on different roms) and i kinda fix this by installing c7 modem(it only happens like twice in a week or not at all) so maybe you guys want to check it out. @mad.maximo
Thanks! Flashing the radio firmware seems to have solved it.
Great!
flashing the c7 worked!!! at last!!!! tks for the tip zaoms

I'm on TugaPowerROM N21, and I solved the HDR problem with Bacon Camera app (available on Google Play Store). IMHO the best camera for our One.

The low free space warning message is related to the filesystem (/system) where GApps had to be installed. /system size is fixed (about 1.3 GB) and it cannot be easily resized. Even more, a full block-based OTA ROM update will potentially restore default /system size. So I will stay with Pico GApps, IMHO the best choice.
Thank you alot
I solved issue with wifi. I do not use HDR so rom is stable for me

Internal Storage is now Internal Shared Storage
Hi Everything works flawlessly but my Internal memory has now become internal shared storage and I'm not able to access my old music files and few other files on my computer which were previously there before Lineage OS. But I can see them on my file manager. What do I do? Kindly help

Hello @zaoms please help me with this. I was on CM 13 and my oneplus one started hanging so I decided to do a factory reset. I did that. After the reset I had a new problem, the WiFi dropping one. I was very frustrated as it would drop every 8-10 mins. And then reconnect. I googled but no solution provided worked. So I decided to change the ROM since CM was down and I wasn't going to receive any updates.
A couple of days ago, I shifted to lineage os 14.1. But now I have a new problem, the WiFi doesn't drop now. It stays connected but every once in a while, it'll not share any data. It stays connected but the internet service won't work. I saw your solution and I flashed the c7 modem as you said yesterday, but I'm still having the problem.
Please help me, I'm very frustrated because I lose connectivity during games or while chatting or even downloading.
Thanks in advance.

Well the only thing about this problem is flashing c7 modem. But there is 2 types of c7 modem one is 00013 which is my recomend and the other one is 00011. Make sure that you flashed 00013 one and if it still exist you can try different modems from the modem topic. Let me know the results.

Hey Buddy! I've observed it for 4 days now. Wifi stopped twice till now. That's better than before. Let me know if there's a permanent fix though.
There's another problem, my Oneplus One gestures aren't working.

Cool! I am using c7 and thats is the most you get. At least i cant find any better. But in time you will see it will happen even rare. I dont had not even single in a 2 weeks from now i guess. About the gestures, i am using the 2102 lineage os build(which is deleted for some reason) and it is working flawlessly. Which means it will be okay with next update so just wait until the new build arrives(about in 2-3 days) and i guess you should be fine.
