Hi Guys,
I have a problem with my nexus 4. I wanted to use cyanogenmod instead of the stock rom, so i rooted my device yesterday and flashed the latest stable build of cm (10.1.2).
Everything worked fine, except for the wifi; it won´t turn on. It get´s stuck on the "turning on wifi"-page, wtih the button in off-position and saying "turning on wifi".
I´ve read some threads were people had the same problem, but nothing seems to fix it. I made a factory reset, wiped cache and dalvik, fixed permissions, but in didn´t work on cm 10.1.2.
So i tried a different build, cm 10.1.1 stable, but the problem persisted. I tried the same things I did on the 10.1.2, but it did not help. So I tried using the latest nightly, but that didn´t help either.
I thought i go back to the stock build to fix it, because it still worked after I rooted the device and still had the stock on it, but unfortunately that did not fix it. I made a factory reset, and wiped cache and dalvik again, but it just won´t work.
Long story short, i don´t know what to do now I rooted and flashed several devices before and never had a problem that did persist even nafter i tried multiple buidls of cm and wiping everything everytime; so if anybody has any idea where this problem comes from and how i could fix it that would be really great

Im having a similar problem, i think we have to flash a different radio ?
Still nothing
Flash a different radio? What excactly does that mean? I must admit I have not heard of that :laugh:
By the way, I just unrooted my device and relocked the bootloader, but that didn´t fix the problem either.
Stock CM Kernel? If so, try flashing kernels with prima drivers. If the problem persists, I guess it may be hardware. On another note, do you have bluetooth or GPS on? Try turning those off and try connecting.

I just tried the franco R163 with prima drivers, that did not fix it. But, speaking of the bluetooth, i´ve just noticed that the same problems occurrs with that. I trie to turn it on an it stays at "turning on bluetooth" without actually turning on. Maybe that helps to know what the problem is.
What other kernel with prima drivers would you recommend?
Edit:
I´ve read through a few threads on that bluetooth-issue, which apparently is more common than my wifi issue. I was wondering if my wifi-issue could have something to do with the bluetooth, because other users who have said bluetooth issue found their bluetooth temporarily on after reboot; then after a while the bluethooth issue appeared again.
In my case the bluetooth doesn´t appear to be on, but i was thinking that maybe it is, but the software fails to display that and that that is interfering with my wifi.
Could that be a possibility?
Out of the box my nexus 4 refused to connect to my TPLINK wr941ND router, wifi was set months ago, nexus 7 works as charm same with evo 3d and others. I thought wtf and turned on wifi on broadband modem, it showed up on nexus 4.... And suddenly network from router poped up as well. I switched off wifi on modem and nexus lost wifi from router. At this moment I went for a walk... When I come back done factory reset, reboot the router, no effect. Changed settings from WPA2/QSS to WPA without QSS - no change, then I changed channel from #13 (best in my location, all my neighbours using #1 and #6) to #1 and instantly nexus found network.... So it seems that sumthing is apparently with wifi, when I changed channel back to #13 it drops the connection and says that networtk is out of range. So finally I checked all the channels from 1st to 13th and it works from #1 to #10, 11 till 13 dunt work. Maybe this info will help sumone with simillar problems.
Ok, I was running PA 4 Beta3 but was having problems with the screen delay so thought I would completly wipe my phone, fresh install PA and install the mini Gapps (I had prev installed the stock but didnt want all the apps)
Here is where it started to go wrong, Phone would not start ptopery, would get past animation screen but that was it, would then just crash with small date in corner.
Wiped and flashed just the Rom and this also failed.
Wiped and installed 3.99 and this seem to work but then the wizard crashed and I had to power down.
Booted back up into recovery and dirty flashed Beta 3 again and this seemed ok. Flashed Stock Gapps and rebooted.
All apps have installed again, titanium back has been run but I still have no network what so ever.,
If i go into settings, more, vpn, mobile networks I get 'unfortunately settings has stopped'.
I have dirty flashed again but still have same problem.
I cant do a complete wipe and install again as need to get out of the office, however with the prev problems I had I am weary about doing so.
Can anyone shed any light on any of the issues i had at all?

Sounds like a radio issue. If you are running 3.99, you need the radio for 4.3 which I do believe 3.99 is based on. You need the radio for KitKat when running the new betas.

This is the easiest way to flash a new radio http://forum.xda-developers.com/showthread.php?t=2607221
If you went up to a 4.4 based rom and it changed your radio to .97 or .98 then you'll need to flash back to a .84 or before.
to go back to 4.3.
I think I basically said that. Sometimes I believe in not holding hands and let the guy/gal do some of the, legwork.

Thank you every one. I have reverted back to my recovery and all is well but I don't understand why when I flash the ROM ad gapps it happens. My recovery is the same ROM and gapps. No idea.
Oh well stuck with the screen delay for now!

Hi mate, thanks for this. I have reflashed my phone again and still have the same problem. My baseband is showing as 84 though s that is correct?
EDIT, dont worry a reboot has fixed this issue. Odd.
Thanks again though.

Hey guys,
I have a Galaxy S4 (i9500). I installed Omega ROM v22 on it and everything went smoothly, Wifi & BT working perfectly.
After a few hours of using the device (nothing special at all, texts and stuff like that) - I noticed my wifi isn't working and by not working I mean that I click the wi-fi button and it changes from gray to the mid-state between gray to green for around 20 seconds before it goes back to green ago.
If I open the menu to see my networks it just says "Enabling" without any networks there.
I had to drive somewhere so I went to my car and tried to enable Bluetooth, and same thing happens there - Bluetooth will not turn on and will stay stuck on mid-state between gray and green for a while and go back to green.
I flashed omega rom v22 again and the problem was gone, or so I thought. I went back to the car for another drive and realized the bluetooth issue is back - and when I got home I realized the wifi issue is back as well.
I figured I need to reset everything so I tried the following:
Full wipe (including dalvik and even including "internal SD card") and then flashing stock rom (from the official website, stock rom of my country).
The issue was back after a few hours. I do not have BT or Wifi access. Yesterday Wifi suddenly started working for a few hours but then it stopped working again.
I really need help! I have no idea what to do with this issue!
Well rule number one when you have problems after flashing without wipe.
1. perform a full wipe and see if the problem persists.

Tried that, no luck.
What else would you try?
In some places when people had problems with Wi-Fi they said to flash a different kernel but I don't see why I would have this specific issue with Omega Rom and why the default kernel with it wont work well?
Maybe this could be a root issue? My root works fine but I have this weird gut feeling like this is some permissions thing that's going on.
I'm trying to think why it would work right after the wipe but then stop working shortly after.
Another symptom: It randomly started working for a few minutes and then stopped again (around three hours ago).
Any idea what's going on?
Well, if you fully wiped and didn't restore any apps and settings then it can be two other things.
Or it's a bug in the rom or a hardware failure in your phone.
I would suggest trying a different rom first. Do not restore anything, not even your google account.
wi-fi fix?
Do you actually have an i9505? or is it a canadian or att version? if its the latter sometimes the devs offer some wifi-fixes, also try a different kernel. otherwise it could be that your radio/modem are not compatible with the version of the ROM you are flashing.
Tried arrow ROM and this issue doesn't seem to happen in this rom. Hope it stays like that...

Hello,
I have posted this on the cyanogenmod forum but everyone seems to be on holiday as I'm getting no replies. I'm hoping someone on here can help.
I recently had CM12.1 running on my S5 SM-G900F for about six months with no problems. I then switched over to CM13 and used that for about a month without any problems.
I decided to go back to CM12.1, I flashed the same CM12.1 Snapshot file that I had been using previously and it installed without error but when I rebooted the phone it would crash and reboot in a loop during start up. I wiped the phone and tried the install again about four or five times having the same problem until on the final attempt it managed to load the OS. Now that I have the OS running I cant connect to WIFI, the 'back' and 'recent apps' buttons on the phone don't respond (the home button does work), the camera app doesn't work (I get the error 'Can connect to Camera') and it keeps crashing and restarting on reboot. Everything else seems to work but the phone seems sluggish and there may be other errors that I haven't come across yet.
I thought that there may be a problem with the zip file I was flashing so I downloaded it again but it did the same thing. I've tried wiping and reinstalling several times but I get the exact same problems. The file I'm flashing is:
cm-12.1-20151007-SNAPSHOT-YOG4PAO333-klte.zip
If I go back to CM13 everything works fine so the problem is only with CM12.1.
I'm at a lost to explain why this keeps happening as I've had this running fine on my phone previously and wiping the phone and starting again doesn't do anything to solve the problem.
Any ideas please?
Come on people! Have a guess, I'm really stuck here!
I myself have not installed any custom roms on my s5 yet (bc of knox 0x0 lol) but try reverting back to the stock rom and then install cm12.1 again, maybe it could work.
Thanks, but I've tried that. Both stock rom and CM13 work without a problem. The issue only seems to be with CM12.1.
Can you tell what bothered you to go away from cm13 back to cm 12.1?

Below is my original post; however, I've since solved the problem. In an effort to help others with the same problem, I've written a Guide, which should explain exactly what to do if your WiFi is suddenly "broken" due to flashing issues.

Many thanks to everyone who offered help, especially subaash and hallo dare, who put me in the right direction.

Greetings, everyone.
Sadly, for specific reasons unknown, my WiFi appears to be completely broken.
Over the last few days I've gone "flash happy" by trying several Oreo ROMs for my OP5. Some worked while others just froze at the boot animation.
Unfortunately, shortly after flashing the xXx-NoLimits Oreo ROM, which got me to the initial set-up screen, my WiFi would not connect. So, I then bypassed the WiFi part and finished the set-up. Everything seemed to be working very well, but I could not get WiFi to work.
Yes, I could engage the Wifi slider to the ON position, and there would be a list of SSIDs; however, oftentimes even my 2 SSIDs would not display. When they did, and I tried to connect, I would see the connection attempt, but it would not complete the connection. Only the word "saved" would be shown under the SSID name. Then it would automatically try to reconnect, but without success.
I've tried virtually everything I can think of to solve the problem, but I can't connect to WiFi.
All other communications work, i.e., Bluetooth, Data, making and receiving calls. It's ONLY the Wifi that's not working.
Yes, I completely wiped my device and re-installed the original OxygenOS (4.5.14), but that didn't work. I also tried completely wiping the device and then installing that latest OxygenOS v4.5.15, but that didn't solve the problem, either.
I went back and flashed all the previous custom ROMs in an attempt to see if any of them would work, but nothing. I tried NitrogenOS, HalogenOS, Liquid Remix, xXx NoLimits, and they all could not connect to WiFi.
I even tried a few WiFi Fix apps on Google Play, but they didn't work, either.
Oh, yes … I even checked my router. It's perfectly fine. I can get WiFi on my laptop without a problem. Furthermore, when I went to a local coffee shop this morning that provides free WiFi, my phone could not connect, just like at home.
Does anyone have ANY suggestions?
Thank you,
Peter
I would say this is to do with your firmware/modem.
I did have this issue on a non Oreo ROM and in the end I just did a dirty flash and it worked.

I've tried flashing both the 4.5.14 and 4.5.15 firmware, with no luck; however, I accidentally deleted my modem nandroid about a week ago.
Do you know where I might find a flashable modem file?
Thanks,
Peter
Addendum: I found the following site for Firmware & Modems:
https://www.jamal2367.com/?dir=OnePlus 5/Firmware + Modems/Android 7.1.1/OxygenOS
I'll try flashing them and report back.
Addendum 2: NOPE! Didn't work. I flashed a few different firmware & modems, 4.5.13, 4.5.14 and 4.5.15, but WiFi is still broken. Yes, I first flashed the appropriate OS version before flashing the firmware and modem. In other words, I always matched the OS version with the firmware & modem version, but no success. Everything works except WiFi. Hmm, still stumped.

Do you have a full rom backup? I mean of the last working rom you had before all the flashing? If so, from a full stock rom (1.53gb or close) of the same build as the backup (ie... 4.5.14) wipe and flash that rom, then wipe and restore the backup you have if the last working rom. If they doesn't work I think you're likely looking at a hardware issue.

So first of all the reason why it is broken is because of the oreo firmware that you flashed earlier. Now what you should do is flash stock recovery and flash the oreo build and boot it up and running. Once you've done that flash the rollback rom (which suppose to downgrade your oreo firmware to nougat firmware). Once you've done it basically it fixes you're wifi issue.

Okay, let me first answer a couple of questions. Like I said in my first post, I DID flash the original ROM, as well as other OEM OxygenOS ROMs, all without success. Yes, I used the exact same ROM that was working perfectly before the problem. Yes, I also had a FULL Nandroid of the working system, but restoring that also did nothing to solve the problem.
Okay, with that out of the way, I went to a repair shop this morning to try and solve the problem. It was unsuccessful. The technician said it's unlikely to be hardware related because I can still get the phone to recognize all local SSIDs. I simply can't connect to any of them. Just like hallo dare said in his post a few back, when I try to connect to my SSID, it tries to connect for a second or two, and then it just shows "saved" and wifi is disabled.
So, for now I'm still completely stumped.

P.S. "Son?" Hmm, I have a sneaking suspicion that I'm older than you (will be 60 in March).
Success ... maybe?
Well, well. It appears the previous suggestions were correct. So far it's successful, but I haven't quite finished the initial set-up. All I can say is that WiFi is working, and I'm grateful for that.
However, it was a frightening ordeal. At one point I thought my device was bricked, and I didn't know what to do. However, with some thought, I was able to solve the problem.
Good news, though, is that I DID NOT have to revert back to Nougat. I'm now running Oxygen Oreo 8.0.0 Open Beta 2.
I will provide a detailed instructions of what I did a bit later. I simply want to get everything up-and-running, which could take a few hours.
Here's an abbreviated version:
Downloaded Oxygen Oreo 8.0.0 Open Beta 1 from here:
http://downloads.oneplus.net/oneplus-5/oneplus_5_oxygenos_openbeta_1/
Downloaded Stock Recovery from Post #2 here:
https://forum.xda-developers.com/oneplus-5/how-to/official-oxygenos-4-5-2-7-1-1-ota-t3627003
Copied both files above to root of device internal storage
Reboot into TWRP recovery
Flashed stock recovery in TWRP
Reboot into stock recovery
COMPLETELY Wiped the entire system ... absolutely everything ... including internal storage. This is where I had the initial problem. I did not wipe everything, including internal storage, and I ended up with a mixture of jumbled numbers and letters when looking at the file structure.
Using ADB Sideload within the stock recovery, I "moved/flashed" the ROM ZIP to the device
After successful sideload, I said yes to installing the ROM
The ROM then installed and, voila, I'm at the initial set-up screen.
Okay, that's all for now. I'll be back later.
