[Q] Wifi stuck "turning on" - Galaxy Nexus

Hi all,
I recently sent my GN (Running 4.0.2 stock, yakju build) back to be repaired because my phones wifi stopped working. what happens is that the phone's wifi seems be stuck "turning on", but never actually does. No wifi icon or anything appears. wifi hotspot doesnt work either. I had my GN from about a week after it was released (I'm in australia so that was about the 22nd December), and around the 15th January is stopped working. This issue cannot be fixed with a reboot, a hard reset, flashing stock roms, toggling airplane mode or anything trivial like that, as I (and others) have tried.
Now i have searched a while on google while i have been without my phone and I'm finding this problem is surfacing for other people too. From what i have seen there seems to be a correlation between 4.0.2 and this issue. Also, it seems to happen some time into the phones life; they do not have this issue when first purchased. I am concerned that this may be a recurring issue which surfaces over time, due to a design flaw or some sort of software issue. If so, this problem will start affecting a lot more people. If anyone who reads this has the same problem, could you please post when it started occuring and what rom, build etc (and anything else which may be helpful) you are running so we can shed a little light on this issue. which many more users i am sure will experience. cheers in advance

just incase anyone actually reads this Galaxy Nexus was sent back, and it was found that the printed ciruit board (PCB) needed replacing. More forums have surfaced since i last checked up on this problem so numbers are slowly rising. Once again, post here if you get the issue, we need numbers

same problem
Hi,
i had the same problem, wifi mac info was not showing anymore on the Nexus. Reboot and factory reset didn't help. Wifi wouldn't come on anymore.
Ask for a replacement, that's the only thing you can do

Can i ask what version of android you guys had? I'm wondering if this is going to be a recurring problem with hardware due to software issues or if it is purely a design flaw (PCB burning out, etc..) Cheers!

I have the same problem which happened last Saturday and it frustrated the hell out of me, i flashed to different versions of OS....didnt help...
restored to factory firmware and didnt backup the pictures and stuff on the phone!! (FML)
and brought it in to Fido on monday to have it serviced....
talking about bad luck...sigh....
they told me the turn around time is 10-15 business days... (N)
will report back once i hear from them

Before the issue happened, did your phone have any other issues? Say heating up while charging or running the WiFi?
I received a device in for repair with this issue and the customer reported it got really hot before the issue started happening. Everything looked fine on the motherboard - the WiFi antennas were intact. Reloading the software did nothing which means it's a hardware issue..
So very strange. I wonder what's causing this.

i remember when my wifi stopped working i was running 4.0.2. I was actually on holidays in Japan at the time and i was wifi hopping quite a lot around the airport (i was walking around and the wifi would go out of range, latch on again... etc) not sure if that had anything to do with it. Hopped on the plane home and i remember i was on airplane mode using an app called colornote. the phone hung pretty hard and i had to pull the battery. rebooted and tried again and after 10 mins, phone crashed again doing the same thing. Got home and the wifi wasnt working. Not sure if any of this had anything to do with it, but maybe. Didnt notice any overheating, but then again i was around snow haha

hi mrmiklepower
just wondering if your phone has been good since you got it back from repair?
i noticed the phone would reboot itself over and over again after i flashed it back to the stock rom. I just called the third party repair shop that my carrier sent the phone to, they told me its still being fixed.
Oh i hope they will return me my phone soon.

My phone is actually still being repaired also. It's been a total of 2 months since i sent if back! they contacted me and all i know so far is that the phones PCD needed replacing. when my phone arrives i will update as soon as i can. should receive it sometime this week, but its not certain. the majority of my ownership of this phone has been me waiting for its return

Holy mother of lord...
I actually called the third party repair shop that my carrier uses to check on the status of the repair. And they told me its actually In quality control which means the problem was fixed and they're just testing it before they send it back to the store where I brought the phone too. Hoping they'll send it in on Monday so I can either pick it up on the day of or the next day.....keeping my fingers crossed.
Will keep you posted on the status of it too.
Sigh

Ok I got my phone back today.
on the reference sheet I got from the repair shop
it states REPLACED PBA, BGA Failure
I looked it up online and PBA means Printed Board Assembly
which probably means the motherboard was defective and had to be replaced.
and now the phone is working fine. So i guess when this phone was made, there were some flaws with the motherboard on it, thus causing this problem.
Anyways, I hope this information helps with others who experience the same problem

Thanks for letting us know! O got mine back today with the same thing. So looks like there is no way of fixing besides sending it back. Good luck to anyone else who gets this problem

So it seems there's no fix for this?
I've been doing some research and it doesn't seem anyone can fix this.. I tried reflashing, wiping every possible thing, etc.. even flashing the stock software via odin. Still no luck.. It seems that we are indeed stuck with sending it back in for a supposedly defective part which seriously blows.
My other question is.. you guys who already received your phones back, did anyone end up with the problem again?
PLEASE if anyone knows how to fix this.. chime in!!!

I had an issue similar to that with my transformer and to fix it I just flash a new kernel im not sure itwill fix the problem for you but it's worth a try

Since getting my phone back the problem has not occurred again. I don't think there is anything that can be done as a component needed to be changed apparently. Good luck :/

Thanks, when returning to stock it flashes a new kernel. Also tried it again for the hell of it with faux's kernel, still no luck .

This sucks! This very same thing happened to me yesterday! I Odined back to stock.. no luck! Now after finding this thread, it looks like a hardware issue! That blows! I'll have to give Sprint a call tomorrow!

Hmm sucks to hear it's still cropping up around the place, I heard someone say this issue entered quality control. But anyway, if it helps I've had my phone back for about a month and a bit and its still going strong. hopefully it doesn't happen again though. good luck, hopefully it won't take too long for your phone to come back!

Hi,
I'm with Telus in Canada and had the exact same problem and had my GN repaired. It took only 2 weeks and I just got my unit back. I had already read a lot online about this issue so I asked the Telus rep to tell me what the issue was. She told me that the report states that the board was replaced. This is definitely a hardware problem. I'm hoping that the new board doesn't have this problem and my phone won't need to be repaired again,
I run 4.0.1 on my phone. Telus hasn't released an update yet. I was going to update mine by switching to yakju, but that's when I noticed that the wifi is not working and I thought it's not a good idea to change the stock ROM.

Is there any hope open to all suggestions

Here's the problem around the second week of this month my boyfriend's Acer a100 bricked itself. When you turn it on it gets stuck on the Acer logo and will not go any further. I called Acer to try and see if they could help me but they stated that it was a hardware issue and to send it in to be repaired; however, there is some major damage done to the screen. It is crack very bad but it is still usable. I'm wondering is there anyone that can give me some advice on how to fix it or what to do to get it where it can be used again. Another thing is I'm thinking that because of the damage done to the device that it voids the warranty, does anyone know if I am right? oh yeah his device is not rooted.

My device had the same problem one day. i messed around with some things to try to fix it and just made things worse , when i talked to acer it seemed as if it was a common thing because in a matter of mintues i was getting the details of where to ship it to be repaired. To my understanding the cracked screen shouldnt be a problem since they would be replacing the motherboard(i believe) and the screen will come back the same way you sent it to them.

I think thats what he's gon have to do because I have clue what else he should do. I wanna call back and ask them will the damage effect the warranty but I'm to nervous they will actually say yes.

Send it to them and if they call you then you accuse them of breaking it...problem solved lol

Updated to Lollipop. Mic-1 not working.

Hi
I'm running an international unlocked M8. just got it from the service repair center for a battery-related repair. Immediately upgraded it to OTA Lollipop. The microphone isn't working. Google Now & Phone calls just pick up static. Speaker phone works fine. Tried cleaning the grill to no avail. Tried factory reset. Nothing.
Do you think this is related to Lollipop? Can I count on an update to follow to solve this? Because I would really hate to send it back to the service center.
Thanks :fingers-crossed:

I would recommend you to try install the previous version you got and if the problem still exists then sorry mate but you have to send it back.
I know it sucks! :/

I guess there's no way to avoid it. Phone's going back not even one day after I got it back I was hoping it was a widespread software issue that would get a speedy patch but seems like it's not. Thanks for the reply.

I'd not only send it back, but I would also let them know that you are angry about it. They obviously sent you something that was sent in to them and refurbished. Tell them you want a NEW phone.

And yes they did send me the same phone I sent to be repaired. It even has the decal I put on the back. And you can see a small indentation from where they opened it up, and the screen is veeeeeery slightly wobbly when I touch it in a corner.
They told me they don't do replacements unless it is wholly beyond repair. Usually the carrier does that but I got this off contract. Though I have heard informally after the third repair they will just send a new one.
I really admire you for your strength . And I would love for this to be a tale of righteous customer overcoming the evil customer support. In my experience the person behind the desk just doesn't care and will only take it out on you if you disrespect him. Whereas being cordial seems to garner astonishment "wow he actually treats me like I am human". I've tried being angry and I've tried being kind.
Thank you very much for your reply.

Need help!! LG G4(H815) not starting

Hi all,
so here is my problem.
Day before yesterday i had a perfectly working LG g4 H815 model with s/n 511 running on firmware v20h, when i decided to root it and install some mods.
so i flashed TWRP, installed xposed and xtrememusic mod. the phone booted normally after installing these. i didn't install any modules under xposed. the phone worked perfectly for two days. however today morning it hanged while taking photo with the camera app. when restarting it got stuck at LG logo for long time. My brother(who doesn't have any technical knowledge) pulled out the battery and restarted. Again it got stuck at LG logo. thinking somthing wrong he again repeated this only to find that it didn't power on at all this time. No LG logo no notofication light nothing.
Tried charging it(although battery was aroung 60-70%), pressing power button removing the battery. still nothing. the phone is not at all powering up.
However when i connect it with USB cable with laptop, laptop makes sound of getting usb connection detected. i took it to a service centre.
the technical guy there told that IC may have been faulty. he told me that motherboard needs to be replaced. however unofficially he may try heating the IC to get it booting.
What should i do now? Is the IC really fried. had the rooting and installing mod caused it?
Please help.
PS- the phone is imported and cannot be sent back for warranty purpose.

I think you are experiencing the dreaded LG G4 bootloop. I don't think rooting or modding caused a software problem. It "may" have caused a hardware problem simply because it generated enough heat to loosen the IC that little bit that initiates the problems you are describing. I rooted and installed the stock image in Nov 2015. Two weeks ago the phone froze - restarted and then could not be booted. LG sent me a Fedex label and I sent it off. Ten days later I received the same phone back. I assume they replaced the mainboard.
You should contact LG directly. I saw a class action suit that was called off because it appeared that LG will fix this particular problem (failed mainboard) out of warranty. Anyone please correct me on this if I'm wrong.

Hi thanks for the help.
But isn't the dreaded bootloop is that where the phone is stuck at the LG logo. Mine isn't booting at all. And the bootloop problem is due to big cores or such and not due to ic?

Mine wouldn't start at all - it bootlooped once for about a split second - then it was dead

Same is the problem with me. Bootlooped twice and then its completely dead. I have tried contacting Lg UK. Lets see what they say.

Ok so i got a reply from LG and they suggested me some steps to take (which are obviously not useful as it is completely dead). however they have also told me that they are willing to help me and asked me about details of purchase etc and "whether it was rooted".
so what should i reply rooted or not? will they detect it as it is dead.

Sorry to be late on reply. I advise to not answer question whether phone was rooted. Here is my reasoning:
1. This problem is widely occuring - only a tiny percentage of people root their phones therefore question is irrelevant.
2. The problem is known to be that an IC becomes loose most likely due to heat - a better question would be - do you place the phone on a hot dashboard with GPS running while you are charging?

thanks for the reply (although late). i have already sent the phone to LG replying as no root. Lets hope they repair it without any problems.
second i didnt do anything of anysort like placing on hot dashboard or such. one day while opening the camera app it decided to just hang and later on die on me.

I hope you didn't think I was saying you might have done something that would overheat your phone such as my second example. I was trying to come up with an example reason the IC loosens. Even if you did that the phone should survive such conditions. Let's hope the replacement motherboards somehow do better. My guess is that the soldering job is fine, the problem is probably bad design that doesn't "vent" the heat from chip.

so what do you suggest after repair should i keep it or sell it? Lg g4 is no doubt the best phone when considering the value for money. no phone even twice in price comes close in camera and screen quality especially. but the unreliability of this phone has made me to consider selling it as soon as i get it back.

I'd keep it if your new board is high serial

Well my old board was also high serial, beginning with 511

I'm going to take my chances - it's a great phone until it bootloops. I'm going to avoid scenarios best I can that could result in the phone heating up inside. That would be charging only if absolutely necessary while in my ProClip dash mount if the car is hot, using backup battery after depletion instead of charging more often etc. Thinking back I rarely put the phone into heat inducing situations - normal use results in the IC becoming loose at the 1 year mark. If mine bootloops exactly a year from now and LG fixes it again I'm an LG fan. If they blow me off no more LG.
I really regret not paying it off early and taking the $15/month deal for an S7 Edge last month

Try some burn-in fix apps from google play, and leave them overnight.
Last solution would be replacing the oled panel.

i heard UV light solves this problem, but i am not sure to do it. i use my phones min. 2-3 years, so i am nervous about that :/

Lol let's start by saying that you got an device with a factory problem and it's seller refuse to five you your money back... that's really bad! You have to do something about it. If you can't do what the guy said before. Download a burn-in app, it can't get worse, can it?
