[Q] CM12-CM11-CM12- Data not working

HI All ,
I had some phone call issues and moved from CM 12 ,Mar19th version to CM 11 version. I had made the back up of CM12 before that.
I restored the CM11 backup that I had ,but on restoring I had issues with promximity because of the modem problem.
So I did a factory reset of CM 11 and even then I had the problem and then moved to CM12 again by restoring the backup.
Now in CM 12 data is not working. wifi not getting connected, data not getting connected.
Calls are possible ..
Is that a problem with modem in CM12 again ? Can i just flash the CM12 modem alone ? How to find which version modem I am having ?

This looks to be an issue caused by your Modem. Just search for CM12 Modem on the forums and flash it (its about 30mb) If that does not fix it you might have to go about it the long way around (Flash CM11S manually and then upgrade to cm12). As a general rule try to avoid restoring a backup of an android version other than the one you currently are on. I would also suggest that you flash the cm12 modem now and do a full wipe after just in case (No need to wipe internal storage)

I flashed the CM 12 latest March19th version and data is working now. But proximity gone

Which ROM are you on? If you're on Lollipop you need to be on Lollipop modem and firmware, if you're on KitKat you need to be on KitKat modem and firmware.

Yeah many people are facing issues with the 19th March Build. Go back to 15th March one or wait for tomorrows build

Yep, FML, I flashed March19 on the way to work this morning and now, no data. I restored my March 12 backup to no avail. I can't D/L anything at work so I am screwed I guess. Would it hurt if I flashed the OPO_L5_alpha_modem? I have that saved

i had the same problem, when i boot it, it shows no service but the signal is present, also i did revert back to CM12 due to rebooting but hope now i when to CM13/Android 5 it will be better

It happens to me yesterday, make me depressed too. After i flashed hydrogenos, want to back to 12.1 suddenly no sim detected and constant reboot, already tried flashing back to lot of kk n lp rom, restore nand backup and flashing fw but useless. And i think my sim card hardware broke. But i googled "hydrogenos no sim" and i got the solution. U can try google it, i think its on reddit, but i cant share here since my gsm operator blocked that web. The point is u have to restore efs. I use bacon root toolkit. As i remember u have to be on kk 44s to restore it, cmiiw, and only when on 44s my opo didnt have any single reboot when try to restore efs. And it saved my life and my opo. Now it can read ny simcard and no constant reboot anymore. Sorry for my bad english and hope it help you, good luck

Use this guide to restore efs .. BTW let your phone cool down first ... And see if random reboots are gone.

constantly resetting the modem was reading vision problems because you use the most recent of which was rum that you can install on your phone sim card again receive the modem's ROM will improve again

Can't get data to work on 5.1 roms

Alright so I've tried multiple roms and I can't get data to work on 5.1 roms even though the APN is setup properly.
I reflashed to complete stock CM11S, then flash CM12S with the firmware/modem/radios update and then the latest CM12.1 nightly ... still doesn't work!
Data works fine on stock CM12S / CM12 based roms.
Is there something I'm missing?

with which recovery you flashed the modem package? (version)

Well, problem identified. TWRP does not flash modem packages correctly above version 2.8.6.0 on the OPO (stated in many ROM and also TWRP threads). You have to revert back to 2.8.6.0 to flash the files or flash the modem via the fastboot commands.

@davebugyi
No luck, I flashed TWRP 2.8.6.0, then the latest CM12.1 nightly. It wouldn't write the modem and radios as it said they were already up to date.
So I flashed the full modem package found at http://forum.xda-developers.com/one...dio-updated-modem-radio-files-oxygen-t3072516
And then I flashed CM12.1 nightly again.
Still no data Should I do the factory reset to CM11S again and retry but this time flashing TWRP 2.8.6.0 from the start?

Can you confirm that your Baseband version is the same?
Also, try to delete all your APN entries and re-add them manually.

Yes I have the same baseband, deleted and recreated the APN entry, rebooted. No success.

I re-did everything (CM11S -> CM12S -> CM12.1 Nightly) and still no data damnit

This is strange. I am out of all ideas, since it should work if you have the correct baseband and manually added the correct APN. My only guess is, that there is a bug in 12.1 which does not like your carrier.
You only tried the official 12.1 Nightlies? Try some custom 12.1 Roms, like Exodus or Temasek or Sultan's CAF ROM as the last resort.

Yeah I'm running out of ideas too! I installed Exodus, same thing. The worse part is that in the past when the first CM12.1 nightlies came out I tried it and data was working!
However it was unstable so I got back to CM12. Go figure
I think I might ask Oneplus support at this point...

I don't know how this much is going to help you, I had the same problem as you for days now, tried flashing various ROMs, oxygen, CM nightly, cm-12.0-YNG1TAS2I3-bacon-signed.zip, cm-12.0-YNG1TAS17L-bacon-signed.zip, cm-12.0-YNG1TAS0YL-bacon-signed.zip, etc etc
Searched various forums, tried various methods, nothing worked, exclamation mark still there
Finally, I deleted ALL of the APN inside the APN selection, turned data off, reboot, turn data back up, went into APN, google service provider APN setting, in my case I'm with Rogers Wireless, entered APN manually, selected the APN, H+ came on after about 5 seconds, restarted phone again, LTE came back on
I hope I have included enough information

Hi, I feel your pain here. I just got mine and immediately flashed the latest 12.1 nightly. No connection from the start. After many hours of BS, I finally found a modem that fixed everything for me.
http://forum.xda-developers.com/showpost.php?p=57125376&postcount=389
Extract and flash with fastboot (zip is not flashable).
Good luck and hope this works for you like it did for me.

I had a similar problem with my Nexus 5 when I first used 5.0. I don't really remember the version or ROM.
I had to change, on the APN settings, from IPV6 to IPV4. The newer ROMs I was trying were set IPV6 by default. Changing to IPV4 did the trick.

Unfortunately it still doesn't work even with that modem

What is your network type under the test menu > phone information? *#*#4636#*#* at the dialer. Mine seems to work at LTE/GSM auto (PRL).
Also in that menu, if you hit the menu button and go select radio band, should be USA.
And finally, in the OS settings > Mobile network settings > Preferred network type should be LTE as well, if you have the LTE service / SIM.
I'm assuming all your APNs are good since you said you had data going before.
One other thing I discovered is that TWRP cannot flash modems properly, even if it's a flashable zip, so they must be flashed with fastboot. There's a variety to try in a topic somewhere around here.

Did you flash *fastboot images* of CM11S?
If yes and still if you are facing radio problems, please refer http://forum.xda-developers.com/oneplus-one/general/ref-oneplus-one-modem-collection-t2858734 and try out KK modems
Otherwise please flash OxygenOS and give it a try.

@Mr hOaX i have flashed fastboot images of cm11s with toolkit and manually too still no service and as i have said i get service on all lp roms including oxygen os. I have tried flashing modems using twrp 2.8.6.0 still got no service whatsoever with kk modems but with lp modems i get service even on lp roms if i flash kk modem i instantly get no service after booting back up.

Firstly, make sure your TWRP is 2.8.6.0
Secondly, flash KitKat firmware before flashing any kitkat ROM.
Thirdly, don't use toolkits.
To your problem, here's my suggestion. Do a full wipe in TWRP. Flash KitKat firmware A FEW TIMES - PREFERABLY 5 TIMES. Each time with a cache and dalvik cache in between. After that do a full wipe again and flash the KitKat rom. Not sure if its placebo but that's what I did to get KitKat working after I switch back from 5.x to 4.4 and have the same problem as you.
If it doesn't work, do a full wipe in TWRP. After that flash factory images except recovery and userdata. You should be good to go to flash my ROM.

By full wipe u mean clean flash or including internal storage?
And thanks will try and report back

Didn't help still got no service tried flashing fast boot image too manually still no service.

Are you flashing fastboot images correctly? Full wipe = wiping system, cache, dalvik cache and data in TWRP

Help! Wifi not working after installing custom rom.

Hey,
I just installed lineage os using trwp, and found that the wifi doesn't turn on. Whenever I try to turn it on, it turns itself back off. When I reset the phone using trwp, I get the error: unable to mount storage. Does anyone know how to fix this?
Thanks.

Did you format system, data, and internal storage before flash LOS??
try flashing again, but with a previous version of LOS, I think I read that problem in last release.

Were you on nougat firmware? Oreo is latest firmware that works, or you could flash the oreo dsp file from leedroids thread..

I have flashed back the stock firmware, and found that the wifi was working. I am currently upgrading the stock rom to Oreo, then I'll try flashing Resurrection Remix using twrp. Hopefully I won't find any issues with the internal partitioning.
