[Q] Wi-Fi connection "completely dead" - Not connecting to ANY network at all !

I have ATT SM-N900A.

Rooted via Kingo root since day one (back in mid December). Never had any issues.

Everything worked just fine - then I lose W-Fi connectivity 'literally' overnight last week.

I am still running 4.3.

There were no software updates or new apps installed when this happened.

In fact, I was on 7 days cruise in the middle of the Caribbean, (data roaming turned off because

the ship was getting expensive 4G service) - when my Wifi abilities completely died. No changes

to the phone that I know of that could have caused this.

I remember checking WiFi on TUE night and the "Royal Caribbean' wifi was available in my stateroom.

At $30 per hour or $60 per day I decided to wait until we get ashore the next day so I could

connect to WiFi in a bar or cafe.

The next morning on WED - once off the ship I tried to turn the WiFi on - no luck. Restarted, shut it off,

took the battery out for a few minutes - still no WiFi the phone does not see and cannot connect

to ANY NETWORKS - None !

Came home from the cruise on Sunday - backed everything up - then performed factory reset

fully expecting to resolve the issue. NOPE :( Still no Wifi of any kind, cannot see any networks at

all - the wifi icon is never bright green like other active icons - it's only dimmed green as its trying to find

networks, then just goes gray (off)

At this point I am thinking its a hardware issue (dead wifi modem?) - EVERYTHING else on the

phone works just fine (the mini SD card is not corrupted - I also tested the phone without the SD card in the

phone as I found one person who had the same problem and the SD card was the culprit)

Talked to ATT customer service tonight. They suggested I go to their local ATT repair facility or Best Buy

Samsung kiosk to get the 4.4 ATT update and then do another factory reset - to see if that fixes the problem.

If it does not - then they would replace the phone under warranty..

I have some questions:

- 1) any suggestion to fix this (if the 4.4 update does not help....or before I even go to get the 4.4)

- 2) if I unroot via Kingo - will they know that my phone was rooted (and potentially deny the replacement

under warranty which they are now offering if the problem persist). I think that Kingo can unroot just fine, but

does it reset the counter?

Any advice or suggestions how to fix this issue with WIFI or how to present a phone for replacement to ATT that

will qualify - will be greatly appreciated.

Thank you in advance.
[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] Rukbat:
There's no "rooting counter". There used to be a ROM Flash counter, but since you can't flash ROMs anyway ... (Safestrap isn't glashing ROMs.)

I'd prefer to not get 4.4, but you can probably restore to MJ5 using the thread here. And I do suspect it's a sudden hardware failure. Software doesn't suddenly break (at least, after 40 years of writing it, that's been my experience). Hardware breaks all the time.

Unrooting via Kingo shouldn't leave anything they'll find. And their tool (in the store) will flash 4.4.2 over 4.3 - but that means no root and, for now, no slots in Safestrap. And if they replace the phone it's probably going to be 4.4.2. (If you go to an AT&T device support center for the replacement, ask really nicely whether they have any refurbs that are still on 4.3 [if that's what you prefer - I have my updater frozen until we get flash and Safestrap on 4.4.2].)
[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] WatchFan1:
Thank you very much for your reply.

I should add that I actually just unrooted via Kingo a few minutes ago.

the "CUSTOM" script with the big lock is now gone from the screen when booting up

and under About Device > Status > Device Status it now reads "Official" instead of "Custom".

How do I check to see if knox counter is tripped ? From what you are saying it looks like I am all set.

Is there anything else I need to do to make sure that they cannot tell that the phone was rooted?

Ultimately, I would still prefer to fix the wifi issue without replacing the phone.

...same as you however - I think that updating to 4.4 wil not resolve anything as i think it is

hardware problem as well.

Thanks for the tip about asking for 4.3 replacement !

PS:

what do you mean by:

"I'd prefer to not get 4.4, but you can probably restore to MJ5 "

What is MJ5, and what is slots in Safestrap ?

Thank you !!

I had a similar issue on my Xperia TL and so I thought I would wipe the OS and reinstall it... HARD BRICK'd the phone on a STOCK install via Flashtool. It wasnt like the phone was rooted either.

Turns out it was indeed a physical modem issue. It took me three days to unbrick the phone... I went through torment to get it unbricked. After it was unbricked... I used it for a few days... no good signal at all. Dang wifi and 4G bounced all over the place. I could buy another modem and replace it. AND then I could use the phone again. I said F it ... got a note 3.

On a serious note, you have a hardware prob bro... futz with it if you like... you will make it really non-functional... pull the warranty and get it fixed.
[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] Rukbat:
Reboot to recovery. (From power off, Volume+/Home/Power.) But I've never heard of Kingo tripping Knox.

It depends on how thoroughly they check. If they look for deleted files they'll probably find something, but they'll most likely flash 4.4.2 first, and that wipes out any signs of the rooting. (The people at the stores aren't engineers or system programmers, it doesn't work, the book says to flash a new ROM, they do it. It still doesn't work, they replace the phone.)

MJ5 is th version of firmware we had before the NB4 update, which is probably what you're on now.

Safestrap is the only way to change ROMs in the Note 3. The bootloader is locked, so you can't just flash a ROM. Safestrap intercepts the boot process and runs the ROM you have in it as the "Current" one. Version 3.71, for 4.3, allows you to have the original ROM plus 4 others in "slots" you set up. So if, for instance, you want to play around with your setup, but be able to get back to what you llike if you mess up, you can back up the current ROM, restore it to a slot and mess around with the one in the slot. Every time you make a change you like, back up again. Make a change you don't like and restore the backup.

Or keep a few ROMS on hand. Maybe one that runs really fast but eats battery like crazy. Another one that's not that fast but you can get almost forever on the battery. Reboot into whichever one you need.

Go to 4.4.2 and Safestrap has, the last time I looked in the thread, only 1 slot. And you can't root 4.4.2 yet. Which is why my wife - who considers it a phone with a few games and a calendar, allowed the update she got the other day, while I have my update app frozen. (Not that it would work with a rooted ROM not in the stock slot, but why ask for problems?)
[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] WatchFan1:
Thanks for the explanation of everything.

I was actually on NB4 already.

Called the local repair ATT center - they do not have any NB3 phones - all replacements are shipped from TX.

To my surprise they did not have the latest 4.4.2 flash and they suggested I go to Best buy !!!! (Unreal ! ;)

Went to Best Buy and a fellow in Samsung kiosk had the ATT version of 4.4.2.

We updated the OS, did a factory reset afterwards - the WiFi modem is DEAD as suspected.

Got back to the office, called ATT customer service. They had me download an app and connected to

my phone remotely so they trouble-shoot it. The tech confirmed that the wifi modem is faulty and they

are sending me a replacement phone.

I tried to request 4.3 and he said that it could be 4.3 or 4.4 (depending how long it has been sitting on the

shelf in their warehouse - but the selection is random and there is no way to request a specific OS version.

Good news is that I do not have to be without a phone and will simply return my old phone in the same box.
[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] Rukbat:
At least you'll get wifi. Keep your fingers crossed that you get an "old phone". Or that the work on SS doesn't take too long.
[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] ptgptg:
Funny enough, I had almost the same thing happen. Went on vacation overseas and turned everything off. Used Wifi sporadically and when I returned home, I had no wifi. Warranty exchange gave me a replacement phone and shortly after that it automatically upgraded to 4.4.2. I actually started a thread but no one had had the same issue as me. Good luck with your new phone.
[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] WatchFan1:
Great news !

My replacement phone arrived yesterday and to my pleasant surprise it is 4.3.

Its actually MJ5 (the original?) baseband - not NB4.

Kernel is from Thu Oct. 17th 2013.

I guess I can just leave it 'as is' correct?

In a meanwhile that baby got rooted on Kingo immediately and the "AT&T update app"

was frozen with Titanium backup really quickly ;)

Thanks everyone for your comments and suggestions.

I was updating superSU on my note 3 after root. I tried to use game killer, only to get the message that root wasn't available. I loaded up superSU and was told that the binary couldn't be found... I downloaded a root checker and it said that root access was there... So I unrooted and re rooted. Same deal.

I'm not sure how to fix the issue.

Can anyone please help

(SM-N9005)
[Galaxy Note 3 Q&A, Help & Troubleshooting] thahim:
Somethings wrong with your su I think. Have to given privillages to game killer in su?

I have given it privileges. But when I open supersu says there is something wrong with su binary.
[Galaxy Note 3 Q&A, Help & Troubleshooting] ultramag69:
Have you deleted then given Super SU privileges back? I find installing a new rom can sometimes screw with them....
[Galaxy Note 3 Q&A, Help & Troubleshooting] BallaratBloke81:
When I first got the phone it had a rom full of provider bloatware. I flashed another stock Roma to get rid of it. Then I flashed xnote and decided OT wasn't for me, so I went back to stock (without bloats)
[Galaxy Note 3 Q&A, Help & Troubleshooting] ultramag69:
Delete the apps from SU then when prompted give them permission again - like normal you will need to re-open them again and get the "Grant root access" prompt from SU...This may work, has for me everytime...

Only other thing I would do if this didn't work would be re-stock and start from scratch...

Or u have done a full wipe from stock recovery after flash stock firmware?

Sent from N9005, somewhere on this earth.
[Galaxy Note 3 Q&A, Help & Troubleshooting] BallaratBloke81:
Yeah, done all of that. Is there a way to manually wipe the SU binary and reinstall? The root checker app says root access is allowed

Is there another way to see if it's the SU binary or game killer having issues?
[Galaxy Note 3 Q&A, Help & Troubleshooting] Rosli59564:
If you attempts to fix root access denied on game killer then it won't work. Gamekiller/gamecih/gameguardian doesn't work with android 4.3 and above.

I however tried gamecih with cm based rom last week & it worked
[Galaxy Note 3 Q&A, Help & Troubleshooting] BallaratBloke81:
OK, so you're saying those kind of apps will no longer work?

What about the SU binary issue?
[Galaxy Note 3 Q&A, Help & Troubleshooting] gee2012:
Its not a superSU issue, guess the dev needs to update the gamekiller app. Do you have root privileges with other root apps?
[Galaxy Note 3 Q&A, Help & Troubleshooting] BallaratBloke81:
Not as of yet. The photo of the warning I posted, comes up when I open SuperSU
[Galaxy Note 3 Q&A, Help & Troubleshooting] gee2012:
Try unrooting superSU from the app itself and reflash the latest (1.94 i think) superSU.zip in recovery or with Flashify (if compatible ,Playstore) flash CF Root in downloadmode. Hope that helps.
[Galaxy Note 3 Q&A, Help & Troubleshooting] BallaratBloke81:
I can't even get into the app to unroot
[Galaxy Note 3 Q&A, Help & Troubleshooting] Rosli59564:
Your SU binary got issue but yes even you solve it those apps won't work.

Try uninstall it from playstore. There is also flashable supersu

http://download.chainfire.eu/204 but I never use it either or maybe reroot
[Galaxy Note 3 Q&A, Help & Troubleshooting] BallaratBloke81:
ES explorer can't get root access either.

Should I flash superSU.zip straight over the top using recovery? Or is that not a good idea?
[Galaxy Note 3 Q&A, Help & Troubleshooting] BallaratBloke81:
I have unrooted (flashing stock rom using recovery) and rerooted (using CF auto root... Or whatever it's called) many times.

I also just noticed this as well. It started happening after I installed the 32 gig SD card. There is a slight delay when I press the power or home button. It's not drastic, but slightly noticeable. I had the GS2 and never had that. Is this something that can be fixed by software update? Besides that one nuance, this phone is excellent in every way!
[Galaxy S 5 Q&A, Help & Troubleshooting] vvveith:
Two things after much research!

This seem to be a hardware/firmware problem. Some of the remedies that have worked for me are: 1.) Turn off auto brightness. 2.) Use a smaller SD card, 16 gigs or less.

Check your battery graph. Is there a constant blue line underneath the graph, if there is, like on mine, I was told it should not be there! I have heard that the only time the blue line should appear is when the screen is on. I am still researching this information but many heads are always better than one. :fingers-crossed:
[Galaxy S 5 Q&A, Help & Troubleshooting] Mrplennium:
Interesting you mentioned using a smaller SD card. I just replaced my 8 gig card for a 32 gig card and that's when I noticed the difference. Why does that affect it though? This phone should be able to handle 128 gigs! I really hope this is software related. I never use auto brightness, so I know for a fact it's the SD card that's causing.
[Galaxy S 5 Q&A, Help & Troubleshooting] vvveith:
Seems to be a pretty good conclusion.

I think certain class 10 high end cards require a certain amount of power to keep them alive? So when the phone goes to sleep for a period of time and the cpu processes down, maybe not enough power, either battery or cpu is being offered to the card. Since more than half of the programs are partly held by the SD card, upon waking the device it takes a some time for it to reassociate all the files? IDK, this is just my best guess as to the why. However, I tried at the suggestion of a few others a program called SD maid available at the Play store and it really seems to have helped so I bought a license to support the author. I highly recommend this app now. It's a very useful tool and for those with root, even more so!

Thanks a bunch guys!
[Nexus 4 Q&A, Help & Troubleshooting] Krazhil:
To be hones, stay away from the N4. Before I bought the N4 I had a Nexus S and was happy with it.

In my opinion there is no "perfect" phone, but the N4 has critical bug: e.g. the N4 will stuck in "deep-sleep"-mode over night if you don't plug in the charger, ALTHOUGH it was fully charged.

I had this bug not only over night. Sometimes it happened when I had this phone in my pocket.

This is DEADLY when you are using the phone as a alarm glock and have exams and I am not the only one with this problem.

I also had other problems like bootloops after random reboots. I tried stock and custom roms and kernels.

I don't know if the N5 has similar problems. If not (I hope so), I would recommend you the N5.

# EDIT: About 2 month ago, I changed the SIM-Card and configured it. After I finished configuring the SIM-Card I put my old back on my N4 -> got stuck in booloop again.
[Nexus 4 Q&A, Help & Troubleshooting] Akash434:
Check for dead spots and ghost touches, its a pretty common on the 2nd edition of of the G4's.

My Nexus 4 is currently facing these problems.
[Nexus 4 Q&A, Help & Troubleshooting] chronostorm:
Unfortunately, my budget won't allow for a Nexus 5, so Nexus 4 is where it's at for me. I'm going to be buying the N4 for $150, so the N5 would be almost double of that.

Looking around on google, I can find some, but not too many people with the deep sleep freezing bug. I wonder how common it is.
[Nexus 4 Q&A, Help & Troubleshooting] rhavasy:
The deep freeze bug isn't that common, nor is it something I've ever had a personal problem with.

One thing to watch out for: as you can see by this board the Nexus is a very customizable device. Make sure you understand what you're getting and if it is truly stock or if the seller installed any custom kernels, patches, etc. Mine for example is running the stock ROM but is rooted w/ custom recovery and has Franco's kernel, an old modem to enable LTE, and the Dalvik optimization patches. The extras aren't apparent at first glance. Asking for an assurance that the phone is truly stock or that seller lists any changes isn't unreasonable. Getting a screen cap of the setup/phone screen might be useful too or at least a look at it if you pick up locally.

For hardware, it's an all glass phone so watch for scratches and cracks. The power button takes abuse so make sure it works properly. Camera is a common complaint so maybe snap a photo of two with it. Finally, you want a clean IMEI so for a Craigslist sale I'd want to see the phone working on a network before I took possession. Ideally seller will have it working, you check it, then they remove their SIM and factory reset it in front of you.

I bought my N4 used off of eBay for under $200 and couldn't be happier. Good luck.
[Nexus 4 Q&A, Help & Troubleshooting] acejavelin:
First, I am going to say I agree with everything [MENTION=943965]rhavasy[/MENTION] said... That being said, my honest opinion for the price of used Nexus 4, you may want to consider the Moto G 16GB GPE (Google Play Edition) for $199, you will also have a warranty and no worries that it has been modified or abused significantly (I once knew a guy that bragged he had overclocked his phone to the point it nearly burned his hand, then he restored it and sold it as "stock")

At first glance it looks inferior to the N4 in most respects, and technically speaking for the most part that is correct, but my son needed a new phone recently and the N5 and other GPE models were way out of his budget at the time, and Moto G was so well reviewed we got one, and it is amazing... it is on par with the N4 in all real world uses, including gaming, plus the battery life is easily double my N4.

If you really are set on a N4, be careful, otherwise, consider the Moto G... Plus the "water resistant" feature of G makes it a pretty amazing phone, check out some of the Moto G water test videos on Youtube from reputable review sites, 30 minutes immersion in water well powered up and no ill effects.
[Nexus 4 Q&A, Help & Troubleshooting] MGREX:
There are many horror stories with used N4s. Because it was a pretty highend phone for a low price at the time many people who bought it didn't take proper care of it so the market is flooded with damaged units with some very nasty scratches. I saw one once, mint condition with its original box and everything yet the screen looked as if someone had taken a fork to it, with a hammer.

Still an excellent phone which should work for you for years:good:
