I was using CM12 on my device for quite some time and everything was working fine. Then I decided to flash CM12.1 and coincidentally, it was the a couple days after CM had announced their discontinuation of CM ROMs. After flashing the ROM all of my WiFi, Bluetooth and Cellular were not working when booted in CM12.1. I thought it was the ROM's bug and then clean flashed the old CM12, but my my WiFi, Bluetooth and Cellular were still not working! So I flashed my device's original firmware like I always did using flashtool "C2104_15.3.A.1.17_Generic". WiFi, Bluetooth and Cellular were still not working in the now 4.2.2. I tried various ROMs - LOS14.1, CM13, Resurrection remix but no luck, my wireless utilities are still not working. Do you know how to solve this? I don't have any data on the device so I am prepared to use any tools/techniques to get the wireless utilities back.

Hello world
I have a 64gb oneplus One. I'll make it simple.
With CM 11S everything works perfectly
With oxygen OS everything works.
With cm 12s or any cyanogenmod based 12 por 12.1 i have connection problems. When i disconnect from a WiFi network, the OPO cant reconnect to data. It just shows an exclamation mark on the signal indicators.
The only way to make it work is to enable/disable airplane mode.
Ive tried every apn configuration from my provider.
Ive tried several módems
What else can i do? Its not a hardware issue because it works perfectly with the avobe mentioned.
Its annoying because i keep missing whatsapp msgs or stuff like that
Thanks un advance!
When switching between ROMs, did you always flashed the correct hardware for the given ROM?
Now i have cyanogen OS 12s. I flashed 11S vía fastboot and got all the OTAS
I have read and searched through numerous threads trying to find a remedy to my WiFi issues. While mine are similar to some, I have some uniqueness. I can flash and set up a ROM and phone successfully. After leaving WiFi range and returning I can neither connect nor access any WiFi settings. While accessing the WiFi settings the phone hangs and then settings crashes. After turning WiFi off and rebooting, everything is fine and I auto-connect to the network after boot.
I have tried a few different KK ROM's: KarbonKat, SlimROM and another whose name escapes me. All provide the same reconnect issue. I have also tried three radios, AT&T 2.20, 3.18, and VODAPHONE 5.06 with no difference in performance. I have successfully flashed Candy5 LP ROM (and all is working fine) but I love the customization of KarbonKat and would like to hang with it. Does anyone have any insight on the problem or any WiFi tweaks that I am missing that could help? I am HBOOT 2.15 and S-Off. Thanks.
I have been running the Digital High GPE Rom, 6/4/15 release. Updated to the M8_FIRMWARE_VZW_001__4.17.605.9.zip firmware. Flashed the 9/18/15 rom, and the bluetooth stopped working. Restored back to the 6/4/15, bluetooth works fine. Tried a few other roms ( CM12, PA, Stock GPE ) all with no bluetooth function. Tried firmware from different source, no luck, went back to firmware uploaded by Digital High, no luck. Bluetooth will only work after restoring to Digital High GPE Rom, 6/4/15 release. Any ideas?
Did you ever figure this out? I can't pinpoint when my bluetooth stopped working, but I can't get it to work even on stock rom..
I had a nightly of CM13 working, but the SD card wasn't working correctly, so flashed the 20160820 snapshot, and everything was good except there was no connection to the sprint network. Wifi was OK. I tried flashing the latest nightly (20160930), and same issue. All downloaded from the CyanogenMod website.
So gave up and tried restoring the backup but it has failed, sdcard issue.
Tried the snapshot of 12.1 but it just bootlooped.
Edit:
So I tried flashing the 12.1 snapshot (20161001), still the same.
Edit:
I flashed this stock rooted - http://forum.xda-developers.com/spr...ment/rom-g900ppca-6-0-1-stock-rooted-t3387717 and got cell signal, but data only for a few minutes.
Any way i can get cell and data?

Thanks for the reply. I ended up reflashing the stock Deodexed rooted ROM and the cell signal came back, so at least I was able to make calls.
I was about to try an old Lollipop ROM, but saw the latest comments on this Resurrection Remix thread all seemed happy, with no issues, so late last night flashed it. So far this morning I haven't seen any problems, I have cell signal, LTE and the SD card seems to be working as intended. Wifi is good too. Just need to checkout Bluetooth and even that's not essential. Will play with it today and see. So I think I'm good for now. Again, thanks for your reply.

Glad to hear! Don't hesitate to inquire if you have more questions
After upgrading my HP Touchpad from CM11 to CM12 (running Milaq cm-12-20161101), my Bluetooth devices can't connect any more. I tried this about a year ago with the same results; hard to believe this hasn't been fixed by now. Before I go back to CM11, is there a something I can do or a different CM12 ROM I should try where Bluetooth works properly?
