Hey everyone,
I'd like to share with you some problems I'm having with Android and possibly find a solution.
1) My Wifi module seems unable to hold the connection when the display is turned off. The advanced setting is set to Never disconnect wifi (even if the display is off) but it still does it. I have tried different settings of the router (MAC filter on/off, WEP/WPA protection, no security at all etc.) but nothing. It disconnects at any wifi I connect to. However I have been able to observe that when the phone is charging, it never disconnect.
2) I cannot set Facebook account synchronization. I see it between all the accounts along with google, exchange etc. but when I click it to set it up, nothing happens and it returns to the initial synchronization screen.
3) If I would like to flash another ROM on the phone to see if it resolves abovementioned problems, I cannot do it through the recovery mode, because it seems Kinzo does not have a recovery partition and is probably part of the boot or system partition itself. Could you recommend me any ROM (possibly Samsung-based) which does not have separate recovery image?
Thanks a lot for your help.

Can someone help me out? I've been using this setup for years on several machines w/o a single problem. Now, all of a sudden, I try to view a networked PC to move some files over (like I've done thousands of times) and it says that the server can't be reached. It gives me some bogus ideas like firewal is on, IP address is out of range, SMB is off, yadda yadda yadda but none of these are true so far as I can tell. I tried deleting the server and scanning via the 'search' again and them same PC shows up. When I click it it gives the same error. So I attempt to manually edit the login credentials or manually create a new server and after I enter all the credentials it just sits on 'Adding Server, Please wait a minute...' Indefinitely. I tried rebooting the PC (Wind7 64-bit) as well as my device (unrooted SGS4 v4.3) and I'm not able to solve this issue. The only changes I can think of is the recent update to v4.3 but I also updated to v4.2.2 previously and had no issues. I've also done this for years on several devices and countless firmware versions & ROMs. I know some have been having issues with the addition of KNOX to 4.3 but I haven't even installed that nor do I plan on doing it. I checked by opening KNOX from the app tray to verify and it indeed still wants me to INSTALL. I am also getting weird warning pop-ups since 4.3 about something or another trying to access part of my phone that it's not authorized to which sounds like a KNOX/WiFi bug from what I'm hearing. This seems strange to me that I would be getting this warning when I haven't even installed it yet. Could this networking issues also be related and how can I correct this? This is SUPER annoying!
I received an OTA Update in early to mid May. I am now forgetting which version I received at that time. ( I forget as I have done so many downgrades/upgrades/factory resets in my troubleshooting the last month!) Up until these issues, I've never rooted or flashed a ROM, or unlocked boot loader or anything. My N5 had always been completely stock.
First Issue
It all started with just the sim card. I get "no sim card" message, even though it was in there. This was my original SIM card and I had never ejected it since I bought it new. I found I could turn it off, pop it out and back in, and boot it again. Sometimes it will see the sim card again. It may take 20 times, but finally work.
I naturally got a new sim card, as well as confirmed said sim cards worked in other phones. My wifi and bluetooth were working fine at first. Working with google support, they recommended a factory reset to fix the sim card issue. Immediately after the factory reset, my bluetooth would no longer turn on nor show a MAC address. At this point, my wifi was fine.
Second Issue
In addition to the sim card slot issue, now my Bluetooth no longer works! Around this time, I received another OTA update, this time it was 5.1.1 LMY48B. I had hoped it would fix the issues, but no dice! I start reading up on the XDA forums as I am determined to start rolling back to see if this will fix anything. I unlocked the boot loaded, rooted, etc following the threads on XDA
Third Issue
I do all sorts of flashing to hammerhead-krt16m_4.4 to hammerhead-ktu84p_4.4.4 to hammerhead-lrx21o_5.0 to hammerhead-lmy48b_5.1.1 . On the final flash back to 5.1.1 my wifi now no longer works!!!!!!!!!!! It is stuck at wifi turning on and no MAC address shows. It also seems my cell data is very very slow now!
After many calls to google, I think I finally succeeded in getting a “ticket routed up”. My phone is from the play store around 10/31/2013. They keep pushing I am out of warranty. I attempt to ask for a refurb N5 without luck so far. I am not very confident anything will come from google. This being my only handset now, it is just not an option to send this to LG. My current state is my voice/txt and cell data are working. Data seems a little slow but usable. Wifi and bluetooth won't turn on. I also still have the sim car slot issue upon rebooting. After a bunch of reboots it will eventually see sim card.
What else can I try? Is there a better way to attempt to repair/reload my radio drivers? Perhaps there is corruption of sorts? I have not tried a custom ROM or radio or kernel…… I did take to a local tech. They looked at everything literally under a microscope and did not see any issues that way. I am in the USA and have a lgd820. Although we are quick to assume a hardware issue, I am wondering if there is some sort of incompatibility with the first run of N5 and lollipop….. who knows!
I’ve read all sorts of threads on the internet. It seems I am not the only one. We are very quick to assume it must be a bad motherboard, it just seems too coincidental to me!

Hi,
This link was actually what i was going to suggest. It seems you've tried pretty much everything in the book except that.
I think its worth a try. Same as any other learning process, take your time and read the whole thing once or twice until you feel comfortable with the process. Then go for it.
Darn it, I should have downloaded those programs BEFORE rooting my phone again. Now I a struggloing to get my SIM card detected again to get data to DL them! whooops!
How would I go about attempting to read my files first to see if they are accessible and potentially write down my old MACs first?
EDIT: I found this but not sure how to get that working? I have Windows 7 and CMD prompt at this point. what program is that using?

OK, I went through those steps. everything appeared to go through correctly. Still no wifi nor bluetooth
EDIT: I rebooted a second time. WHen it first boot up, wifi was on and connected to my works AP. I quickly went in and snagged a screen shot of MAC address. Oddly enough, it did not match what I had input via hex editor. Within a few moments the wifi stopped working. It is back to the turning wifi on issue..... bluetooth still not working as well.
Very interesting.....
EDIT2: I get access denied when attempting to read either files within their corresponding folders under persist.
I was able to copy my stock files into my sdcard download folder and read them there without issue. Thus seeing my default addresses for both!
Perhaps it is normal, but I am never able to edit the old or new files under persist. I basically renamed original folders to bluetoothold and wifiold. I could delete them perhaps.
Note that I put my phone into airplane mode before doing anything noted in the steps.
Any other ideas? Given that it is showing my original MAC address the one time it worked, this makes me think that it is not reading the files .macaddr at all
I have the same problem. Funny thing is, the phone is just over 2 years old and the motherboard was replaced just 9 months ago (so, brand new one).
In my case, I received and Android update 2 days before I found the phone burning hot and restarting on it's own. Then the same chain of events you describe started to unleash. Now I can't be sure if this is software related, hardware related or both.
Can't seem to find a solution to the issue either.

I'm facing the same issues and I tried all the possible steps I could find on internet trying to repair the problem.
Actually, since the latest updates I was encountering some issues with the WiFi only: not turning on either off and not showing properly the MAC addres. So I decided to factory reset, even SDcard and since yesterday I have tried all the possibile guide I found to internet to fix the MAC address not showing and the WiFi not turning on/off but nothing worked. I tried even to flash again the old factory images, such as KitKat, Lollipop, etc., to lock the bootloader again and to dismantle the phone in order to clean the motherboard, but nothing worked. Phone still gives me MAC address 02:00:00:00:00:00 alternatively with the correct one, I can't figure out on what it depends because sometime it seems to work: it shows the correct MAC, it connects to wifi network; suddenly it doesn't!
I'm really going crazy to understand what's wrong.
You'll have to dig up my final posts on this , but in a nutshell, send into LG for repair, select cheapest option they offer. Receive mint phone. My cost was $45 and about one month... I picked up a cheap $20 phone to get me by.
In other news.... I now have a 6p!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi,
I don't know exactly where to look for help. Because, it could be a CM13 problem, a Oneplus One problem, a Titanium Backup Problem or a general Marshmallow problem. Please guide me in the right direction, where I could ask! (Or if you know the answer, I would be even happier).
///(writing this after everything followingWow, I really wrote A LOT. tl;dr: I can’t edit/delete my wifi connections on Marshmallow. I think, it’s because a new rule of Android 6, which prevents other apps (in my case my network settings) to change stuff (See paragraph 6). I have 2 assumptions (paragraph 7+8) but I still don’t know, how to change/delete my wifi connections. help!///
I also want to say, that I already asked in some german boards (hence I'm from germany), where I was immediately dismissed, because quote: "It's your fault if you install nightlies. You don't get help, if you are so stupid". Well I can't understand this point of view to some extend, but I still don't know, if its really a "nightly problem" or one of the other suspects. Please don't dismiss me directly. If you have a clue, please point it out.
Please also note, that I have under 10 posts, which prevent me to post links. I really don't want to spam and I hope I don't break any rules, but I included links to pictures in my posts. Not to spam, but because I think it's helps understanding my problem.
So lets get to it:
The used status: I was on the official CM12.1 nightly and have done updates 1-2 times a week. At university I use a TTLS/PAP connection with a certificate and my credentials (eduroam -> eduroam. org/index.php?p=faq#technology). At home and work I used a normal WPA2 connection.
What I did: I updated yesterday to official CM13 nightly with OpenGapps for Android 6. Not via the updater, but via Recovery. I did a full system backup beforehand with Titanium Backup. Booted into recovery (TWRP), wiped the usual stuff (factory reset + system partition), installed CM13 and OGapps, rebooted and setup the phone. Then I did a full restore (all data + missing apps, cause I didn't want titanium to overwrite the new Gapps). Everything worked out great. Phone runs great, my daily apps run great, no crash so far. Quite nice for such an early nightly.
Now my problem: I went to my university library 2 hours ago to work on some things in the evening. My phone is was not able to connect to the wifi (authentication problems). Than I tried to edit the network and saw, that the settings were lost (as well as the certificate). I downloaded and installed the certificate and set everything up in the edit network panel. On save, it just gave me the message: Couldn't save network (imgur. com/fBDctvE.png). So I tried to delete the network, to set it up from scratch, but I can't delete it (imgur. com/2I29bSR.png).
I did some research I found people who had (It looked like at that moment) the same problem, of not be able to edit or delete a wifi connection. So one pointed out, to settings -> backup and restore -> and reset all network connections to factory state. I did that, but all the saved connections are still there. It can't delete them. Then somebody else with such a problem, said, he couldn't delete his network setups, but with an external app (WiFi Manager) he was able to delete the networks.
Which brings me to my current point in time: I tried the app, it was not able to edit or remove my networks, but it gave me one valuable information, which is maybe the key to my problem: imgur.com/ t2JmYml.png . It says, that: "Under Android 6 only the application, which created the network, is able to edit and to remove it."
Now I have 2 assumptions:
1) It’s a problem because I restored my data via Titanium Backup. If I look at my saved networks, than I also see, that the „owner app“ is now indeed Titanium Backup (imgur. com/I44ys5s.png) and NOT network settings. Which, if I understood correctly would prohibit network settings to change or delete networks, because of: "Under Android 6 only the application, which created the network, is able to edit and to remove it.“
2) It has nothing to do with Titanium, but instead is a problem, because the networks were created with the older version of Network settings (Gapps for Lollipop). And I did a fresh install of Gapps for Marshmallow. So maybe „new“ Network settings thinks, that it didn’t create the networks, but instead they were created by „old“ Network settings.
Either way, thats it. I really don’t want to install Lollipop again just to delete the networks and than again install Marshmallow and recover everything and setup stuff.
Did I miss something? Do you have different ideas, what I could try? I have root and busybox installed, could I maybe delete the networks „manually“ via Terminal Emulator, or could I adb into my phone and search and delete these settings? I was not able to find them, but honestly: Without somebody here pointing me at the right direction, where the network profiles are stored, I would not mess around on my own. Can you help me?
Thank you!!!
Hi,
To better assist you, please post your device model number and I will guide you to where you may find your answer.
Thank you.
THE ORIGIN OF THE ISSUE:
Everything began 1 month ago. I was using my Nexus 5 like I always did. I had my WiFi turned on because I was chatting with my friends on Instagram and I left my smartphone charging. There were notifications and the notification light turned on showing me that I had two texts from Instagram app. When I tried to turn it on the screen, I pressed the power button, but the screen did not turn on. I pressed the power button again and again and again, but still the same. I tried to force-reboot my device and that's what I did. When the screen started again, my WiFi was stuck at "turning WiFi on...", also, my Bluetooth was not working properly too, because when I tried to turn it on, it automatically turned back off.
ATTEMPT TO FIX #1:
First thing I tried was unrooting and reinstalling stock using Nexus Root Toolkit. That didn't work... I tried doing a simple factory reset from the phone settings, also didn't work...
After those fails, I noticed that my MAC address was corrupted, showing this: 02:00:00:00:00:00 so I searched the Internet for stuff related to this MAC address error and found people with similar problem just like mine. I found solutions like deleting /persist/wifi folder (my friend did not recommended me to do so after I did this). So, I did the thing, AND IT DID NOT HELP. Tried returning to stock using Nexus Root Toolkit AND IT DID NOT HELP. I had an idea to delete my entire system using TWRP and I thought that reinstalling it would fix the problem. But I was noob at the moment, didn't know how to flash after deleting it. Anyway, I went on, and deleted system, but I didn't know how to reinstall and I was without a smartphone for 3 weeks. I was sooooooooo sad cause this was the worst issue I had to deal with... No smartphone... No WiFi.... life sucks (still does, I am sooo depressed for a stupid smartphone)... Well, obviously, NOTHING HELPED.
ATTEMPT TO FIX #2:
After those 3 weeks, I finally managed to find a way to reinstall OS on my smartphone again (using Nexus 5 factory image found in Google site for developers). I was sooo happy because at least I managed to turn the smartphone back on. So, step two was to check if WiFi worked. Well... not as I expected things to be. It didn't work... Obviously... Well, after doing simple experiments, I tried to do "the thing again". After deleting file .macaddr from /persist/wifi folder, without deleting the folder, only the file, WiFi turned back on!!! I went in tears thanking God. Sooooo much happiness!!! I desided to insert WiFi APs that I prevously saved in a wpa_supplicant.conf file, and guess what.... I F***** UP WIFI AND SENSORS!!! I was sooooo mad!
ATTEMPT TO FIX #3:
Well, the next day, I attempted to do a system delete again, but this time, I used another computer device, my family laptop. I deleted system, and this time, I didn't flash anything using Nexus Root Toolkit, but I used this Nexus 5 factory image again. WIFI WAS BACK ON!!! YEESSS!!! I was crying soooo hard!! I again thanked God!!! But it didn't last long... After two days, I turned on my WiFi to check my messages from Instagram, sadly, my WiFi was again stuck on "turning WiFi on..." and my smartphone rebooted by itself (again). So... guess what. I DEAR YOU TO GUESS WHAT HAPPENED NEXT!!! MAC address was back to this STUPID 02:00:00:00:00:00. I had enouch. I installed Termux, I installed a packet called "macchanger" and tried to change my MAC address to something random. I used command "macchanger -r wlan0" and I rebooted. This changed my MAC address to something random. Now, WiFi turns on and when I open an application to use WiFi with, it turns off immediatelly... Also, my MAC address is on changing again with command "macchanger -r wlan0" and is stuck in the previous randomized MAC address. Using "macchanger" command, I also noticed that my "permanent" MAC address is now: 00:00:00:00:00:00 (something that was never valid).
WHAT DO I DO?
DO I NEED TO BUY A NEW SMARTPHONE BECAUSE THIS ONE IS PRETTY F***** UP?
DO I NEED TO REPLACE THE ENTIRE MOTHERBOARD?
IS THIS EVEN A HARDWARE ISSUE?
IS THIS A SOFTWARE ISSUE?
DO I NEED TO REPLACE FIRMWARE? IF SO, HOW DO I DO THAT?
DOES THIS HAVE SOMETHING TO DO WITH /PERSIST?
WHAT DO YOU PROPOSE? BECAUSE I AM TIRED OF THIS STORY, REALLY...

I was sooo happy because at least I managed to turn the smartphone back on. So, step two was to check if WiFi worked. Well... not as I expected things to be. It didn't work... Obviously... Well, after doing simple experiments, I tried to do "the thing again". After deleting file .macaddr from /persist/wifi folder, without deleting the folder, only the file, WiFi turned back on!!! I went in tears thanking God. Sooooo much happiness!!! I desided to insert WiFi APs that I prevously saved in a wpa_supplicant.conf file, and guess what.... I F***** UP WIFI AND SENSORS!!! I was sooooo mad!
ATTEMPT TO FIX #3:
Well, the next day, I attempted to do a system delete again, but this time, I used another computer device, my family laptop. I deleted system, and this time, I didn't flash anything using Nexus Root Toolkit, but I used this Nexus 5 factory image again. WIFI WAS BACK ON!!! YEESSS!!! I was crying soooo hard!! I again thanked God!!! But it didn't last long... After two days, I turned on my WiFi to check my messages from Instagram, sadly, my WiFi was again stuck on "turning WiFi on..." and my smartphone rebooted by itself (again). So... guess what. I DEAR YOU TO GUESS WHAT HAPPENED NEXT!!! MAC address was back to this STUPID 02:00:00:00:00:00. I had enouch. I installed Termux, I installed a packet called "macchanger" and tried to change my MAC address to something random. I used command "macchanger -r wlan0" and I rebooted. This changed my MAC address to something random. Now, WiFi turns on and when I open an application to use WiFi with, it turns off immediatelly... Also, my MAC address is on changing again with command "macchanger -r wlan0" and is stuck in the previous randomized MAC address. Using "macchanger" command, I also noticed that my "permanent" MAC address is now: 00:00:00:00:00:00 (something that was never valid).
WHAT DO I DO?
DO I NEED TO BUY A NEW SMARTPHONE BECAUSE THIS ONE IS PRETTY F***** UP?
DO I NEED TO REPLACE THE ENTIRE MOTHERBOARD?
IS THIS EVEN A HARDWARE ISSUE?
IS THIS A SOFTWARE ISSUE?
DO I NEED TO REPLACE FIRMWARE? IF SO, HOW DO I DO THAT?
DOES THIS HAVE SOMETHING TO DO WITH /PERSIST?
WHAT DO YOU PROPOSE? BECAUSE I AM TIRED OF THIS STORY, REALLY...

You said you were rooted.
Any chance you made a backup, especially a backup from the efs partition?

What is EFS? What backup do I do. Cause, I'm a noob and all, and I am not the type of a developer... But, I guess I am able to do a backup using root. But how will this work? How will this help the situation. Could you explain to me friend? (If you are willing to do so of course)

Maybe you want to have a look on this thread: https://forum.xda-developers.com/t/...y-are-and-how-to-get-it-back-if-lost.3307793/
EFS stands for Encrypted File System. […]
It contains your IMEI, lots of files revolving around your SIM card and Wifi/Bluetooth (this includes your MAC address for all the radios of your phone), and lots of other things that should never ever under any circumstance be deleted or touched. […]
If you lose your EFS folder, you lose pretty much any chance of your phone being able to use data, Wifi, Bluetooth […].

If you had done a backup (e.g. via twrp) prior to rooting you might have also done a backup of that efs partition.
And if you had a backup you could restore that partition. Don't know if you somehow managed to mess this partition up (or if its related at all in your case. Someone with more knowledge hopefully sees your thread) but if you did, there would be no point in backing up that partition now (if its damaged, there is no use to backup a damaged partiton to restore it afterwards).
You can ask me everything you want, don't worry. But I don't know if I'll be able to explain it.
You could try to follow above mentioned guide. If it works, please upvote that guide so others find that helpfull content too.

I did not mess with any partitions. I do not like to mess with my system. I never did. I always made a backup if I had to do something with the system. Before the incident, I never EVER messed with the system. I only started some experiments after the thing happened. I first deleted the whole content of /persist folder (which I restored, because I had a backup), then I deleted .macaddr file inside /persist/wifi folder which actually turned on my WiFi access again, only to f*** things up after doing something stupid, which is to replace wpa_supplicant.conf file inside the /data/misc/wifi folder with one I had with my previously saved WiFi Access Points and their passwords, which resulted to the corrupted MAC address again (02:00:00:00:00:00). No, my WiFi can be scanned successfuly and I am able to connect to it, but still, it does not work properly, because when it connects, it automatically disconnects when I try to use apps like Chrome and Instagram and other apps that need Internet to use. I am currently deleting and re-installing my Factory Image and this will be the last time...
Also, I will attach your URL for sure.
Thanks.

Another thing which would be helpful:
If your problem is still present you might want to have a look at the logs. That way it's easier to see what causes this behavior.
Code:
adb logcat > log.txt
Run this and try to reproduce the error.
Don't worry about messing with anything. We don't know what happened and sometimes the best of us do things they shouldn't do.
And it seems that also other things (like installing a custom OS) messed with partitions somehow.
But yes, doing a backup prior to modifing is extremly wise – keep up that habit!
I would suggest to try this solution I found:

My Solution {Nexus 5 stuck on "Turning wifi on"}
MY Nexus5 got the same problem today WiFi just stopped working suddenly. The mac got some stupid address like 2.00.00.00. I tried every thing still nothing. I have already rooted my nexus so tried different roms but issue still remains.
Then i just remembered about the ROM UBUNTU Touch i have installed it and WiFi in Ubuntu start working again with original mac address. I am currently using Ubuntu touch and didn't try to reinstall or reset the android rom again.if some one try this and got WiFi working like me please inform me that if the WiFi still works if i reinstall android system.
If you want to download Ubuntu touch download it ubports

It is said that the "fix" stays after Android is reinstalled afterwards.

I saw this thread before. I did not try to flash other OS than the one I use now. I was also thinking downgrading to Android 5.1.1 (because I am currently using 6.0.1 with MOB30H build) and I might try some time.
BTW there is another problem now. I installed a packet from Termux called "macchanger" and I used the packet in order to - what else - change my MAC address. The packet seems to work. It DID change my MAC address and I am now able to scan for local WiFi. But the thing is that every time my I try to connect ti the Internet, WiFi automatically closes, and the randomized MAC address is permanently stuck ( I think, because I can reset it sometimes, but still, it changes back the the one who got randomized first)
I may get a new smartphone for WiFi, calls and stuff and use my Nexus 5 in order to try and find a fix for it. Idk...
