I am having a very annoying problem with my Rogers I727R S2 phone on ICS stock.
The problem started to increase in frequency to become a real pain.
My phone would suddenly freeze and stop responding to screen touches for a bit, sometimes as long as 2 minutes, before bouncing back. When it comes back, it initializes as if it is restarting, so I would feel a vibration, lose all open applications and see icons start appearing on notification bar one by one. The media scanner would start working and software installed on SD card start appearing.
The problem happens spontaneously and out of the blue. It was occurring at less intensity on gingerbread before upgrading to ICS. After upgrading, it was not that frequent until only recently.
I noticed the problem goes away when I remove the SD card or when I am on flight mode with no Wi-Fi. I changed the SD card but this did not help. Connecting from home or work does not differ, so a problem with Wi-Fi would be ruled out. I once had a problem with home Wi-Fi when somehow the router’s DNS was not resolving, when this problem of mine was at its prime, and my phone was rendered unusable as it only takes couple of minutes before acting up.
I spent quite long time searching for an answer and so far no luck
I just placed a video illustration of the problem, and hope to get feedback on even where to head.

Try a different launcher.
the only way to troubleshoot is to start from scratch, read my 2nd link in my sig to restore to stock ics, reset within the recovery when odin finishes flashing, also keep out your sdcard out just to make sure your sdcard or its slot is not the problem. if still having probs its hardware failure, should still be under warranty

I went through your instructions restoring to stock ICS (which did not wipe my data as I thought it would). This did not help though, and the problem persisted. After that I decided to a hard factory reset. This appears to have done the job and my phone was working very smoothly.
Because my phone is rooted, I restored to the buggy stock again using CWM in hope to be able to figure out how to my migrate my purchased software, data and settings after hard reset. I wonder if there is a way to preserve important files even with replacing systems. I want to hard reset again but I keep my important information

after restoring stock perform a reset in the recovery, if old data is still there after reset its a hw defect in the nand
edit: reread your post so nm what i just posted, use titu or other backup software
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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I didnt root or unlock it myself.... im pretty sure i wiped all data before flashing the rom i have on there now, but i cant remember for sure....
seems to be the only way to truly fix my extremely messed up WIFI situation... (wifi kills my phone completely... regardless of whose internet as i tried my neighbours and got the same error). i did a restore to last year but it only fixed it for a day... if im gonna restore to a year ago again, i figure i may as well do a full fresh install, since its crapping out still anyway
i have something called superuser (i know is root access), and something called stk which ive read is sim toolkit, in "system/app" they are both apk's. "superuser.apk" and "stk.apk"
also, will my custom recovery be gone? as far as i remember that is how i flashed my ROM last time... but its been so long i cant remember...
Let me try helping since myself new on forums:-
There are two types of phone resets available- 1.Factory wipe from settings of phone/from custom recovery (cwm/twrp) or 2.Complete wipe performed such as in upgrading os version of android (like i did lollipop from jellybean). The complete wipe is done in custom recovery only under mounts and advance option in cwm and then wiping cache,system,data and everything else. If you do so,you will be losing everything installed in your phone EXCEPT Root and Custom recovery.
Back to your question, if you perform factory reset,NO,you don't lose root. If you do complete wipe from recovery,still you don't lose root of your phone UNLESS you fix the root on reboot.
Choose the reset carefully before installing any rom,read their steps,if they ask full wipe or just factory reset and dalvik cache.
Hope it helps.

you cannot unroot yourself thru factory reset

Factory reset WILL:
Remove all apps and their data
Contacts that are not on the SIM card
(In some rare cases) Pictures, music...
Factory reset WILL NOT:
Remove carrier unlock
Remove root (but may remove superuser app)
Remove the recovery
In case that superuser app is gone, just install that same superuser app from Google Play and update it if it asks to do so.
Ok, let me ask this, to ask if its even worth me doing....
last night i did the same restore to a year ago... except this time while i still had wifi i had downloaded both avast and AVG
I can with both now, and my phone says its clean...
but yet the problem is recurring now, and wifi, 4g, tethering..... basically any function that connects me to the world outside completely craps out my phone...
i thought the restore, and especially he restore and downloading antivirus would fix it, or at least be able to tell me WHAT the problem is... avast will scan the wifi network, but of course this test now freezes up just the same cuz it has to turn on wifi to do so.... while it was still working this test did execute just fine with no errors....
its as soon as internet is connected... for 3g or even my router, it will read it without the internet feed plugged in. but plug that in and it all goes to crap again. Id just hate to do a full fresh install just for it to all go to crap *again*....
ive scanned all computers on the router and those come back clean/no viruses... i tried i different router with internet, same error. i tried the neighbours connection.... same thing again.
this is really baffling.
so i feel more comfortable doing a factory reset....... but i guess im wondering is will it help me??? at all????
whatever this is is clearly not an infected device as some on another forum had thought.... something *else* is going wrong....

Factory reset fixes all problems that were not made with root. You will not lose root either. For a total fix just wipe everything and reflash rom.
Right now im trying a different router, which doesnt have any windows XP machine plugged into it, and i made it extremely secure. even changed the default username and password to get onto the router itself (never bothered with the other one, the one i had been routinely using)... I did a complete reset of this router before even connecting to it with my phone, after it was secured. the other regular one still has everything else connected to it. this one is literally a separate connection, which i named "phone test" lol.
if it makes no difference, total fresh install is my last resort. if it *does* make a difference however... then something in my other regular router is messed up that cause my phones connections to freeze up - but that avast or AVG wouldnt detect (thats the only weird part)...
i even did a scan of my external SD card the other day, thats clean too.
time will tell, im approaching the 24 hour mark with this new setup. if by tomorrow its freezing up again, its not the router. but if its still working, ill have extreme suspicion that it was in fact, the router, probably something dealing with my XP machine thats plugged into it (well, normally anyway).
Time will tell...
im also trying to remember which apps i had updated before any problems started in case there are any corrupted updates i installed, without knowing it. (legit from play store, but still, ive heard that doesnt always mean totally safe, cuz anyone can make them)
Dude, wipe data, cache, system, reflash rom on your phone. BUM, problem fixed.
I still may, but i wanted to play around with the routers first to see if i could fix the problem.... that way id know i wouldnt be fully wiping for no apparent reason. if in a week or so things have been fine and i try connecting to the old regular router... than ill know its something on there infecting my phone... id rather not have a fresh install crapping out on me.
You can do a nandroid backup and then reflash everything. That way if you screw something up or the problem is not fixed you can restore in minutes.
So been running c59 Android 11 for a couple of weeks. All working pretty well when today i noticed my device was not on Wifi..
I went to wifi settings the phone locked up and crashed - rebooted.
Same thing is occuring except now i have a little Sim icon and an X in where the celluar signal is.
I still can recieve calls though no network access at all!
Just tried aeroplane mode and now its stuck and i cannot turn off aeroplane mode..
tried the reset network settings.. no change..
this phone is rubbish.
looks like another factory reset coming up...
just for anyone else who has this issue. you need to Format Data through recovery.. you lose everything. this fixed it for me.
You lose nothing because people are supposed to BACKUP their stuff.
Smartphones haven't been around since only a few weeks ago, it shouldn't come as a surprise that at some point they can fail or like in this case for some reason need a formatting.

If you think about it you should be able to format Application Data only and not lose your photos etc..
Even my old Nexus 4 from 9 years ago can do that..
actually every phone i have ever had could do that other than this one.
Why would the existence of personal photos cause a phone not too boot? So why would the manufacturer make you format them to reset the phone?
Just a poorly designed device really..
And for the record i did backup and do backup. Though i wanted to inform others who may have to perform this fix that they will lose data.
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...

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.

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...
