[Q] Bluetooth works but suddenly causes bootloop. Is this due to faulty firmwares?

Hey guys, I bought a Galaxy Nexus almost a week back but as its not launched officially in India its not under warranty and so I can't get it replaced.
Out of the box it came with ICS. Everything was going fine including Bluetooth file transfers. But the phone went to a boot loop (stuck at boot animation) when I tried to activate Bluetooth. Mind you that Bluetooth had been working fine, I got this issue all of a sudden.
I went into recovery mode and recovered my phone but all data was lost.
Later I updated to official stock ICS. Again the Bluetooth worked fine for few days and later suddenly went into a boot loop. I recovered my phone but this time too lost all my data.
Now I'm obviously very scared to use Bluetooth. Some people say that its a faulty firmware and I should flash another firmware.
What shall I do? Could this really be a firmware issue? And if yes then which firmware shall I flash and how to flash?
Currently I'm on stock JB on my GSM GNex which is unrooted and has a locked boot loader.

Never heard of this. With all data lost, do you mean the /sdcard partition as well?

I'm sorry I didn't get you. GNex doesn't have a SD card slot, right?

Correct. That's why I said partition.

Well this is my first Android so I don't know much about partitions.
Well when I wipe my phone / factory reset, ALL my data gets removed including images, music, videos, contacts, messages, calendar events, 3rd party apps, etc.

Someone please help.

Bluetooth Boot Loop
Im having the same problem.. Please let me know if you found a solution.. I'll give you update if I find one myself..
The list of Android units that I have encountered this was with
2 units of Asus TF101G and 1 unit TF300T
My TF101G was fixed when I installed a Custom ROM (Revolution HD)
I'm open to rooting my phone but not to unlock the bootloader to keep the warranty..
Hard Reset fixed it but after a few days when I activate the Bluetooth it will start with the Boot Loop.. It's very frustrating to install apps and everything.
Perhaps is it related with the files I installed?

Afaik, bluetooth radio is controlled by the baseband. What version are you guys using?

Im currently using TF300T
Asus Official WW Jellybean ROM
I think It's not related with the JellyBean coz I expereienced it with ICS before when Im using TF101G

The baseband of my GNex is I9250XXLF1. I am on official JB (4.1.1) on yakjuxfw.
Please help me, this is really annoying and I'm very scared to activate Bluetooth now.

You are on the latest baseband and Android version. And since you are completely stock and the problem also manifested itself on ICS, I'm going to say you are probably having a hardware issue there.

That's really sad to hear. And as the GNex is not available officially in India, I can't get it replaced either.
BTW you said 'probably', what can be the other possibility?
Well I too have something to elaborate. Both the times (on ICS and JB), the problem occurred while activating Bluetooth from Notification Toggle (downloaded from Play Store). It's not that whenever I used Notification Toggle did the problem occur. Several times Bluetooth successfully got activated using Notification Toggle.
So as much as I feel that it could be a problem of Notification Toggle, I feel that the opposite is possible too.
Another thing is that I had downloaded a paid app for free from a torrent website. Tapatalk to be precise. Many of my friends suggested that and I wanted to try it out and so downloaded it from torrents. On both bootloop occasions, that 'pirated' copy of Tapatalk was present in my phone.
Now I have purchased Tapatalk, uninstalled that pirated copy, uninstalled Notification Toggle and now I just tried three Bluetooth transfers with my system (2 send and 1 receive) and they took place perfectly. Is it possible that the pirated copy of Tapatalk was causing the issue?
I know it's not ethical and even against the XDA rules to discuss about such pirated copies but I didn't want to hide anything when asking for a solution to my issue.

If the problem happens again, I think you have to return it to where you purchased it from as it may be a hardware defect. Let's just hope it doesn't happen again. And I know you mentioned India does not officially sell the Galaxy Nexus. All the best!

and yes, it happened to me too. Its bootloop, then i took the simcard out, then power on again, but takes a long time, only X logo for more than 10 minutes. Then its going to menu. Then, well, i check the settting, turn on the bluetooth again, bump ! it happened again.
FYI, device not rooted, bought three days ago, and its LOCKED.

Is the problem solved for you? If yes, then how?

@Kanded: Can you please tell whether it's solved or not?

The same problem with me!!
Not just in the GNex, it also happens with me in my HTC One V.. I can't find a fix anywhere on the internet? There's no one who can tell why this happens? I change ROMs but still it happens in every ROM! :crying:
I use Bluetooth for a few days... and BOOM! on one day it suddenly goes into boot loop....

That is exactly the issue I face, exactly the same.

Ive lost completely my mobile signal

Hey guys, this afternoon my phone turned off itself becouse of the lack of battery life and then it completely lost its capacity to connect to the network ( in order to make calls ).
Its kinda rare becouse when I press and hold the power button to get access to the power menu it says "airplane on" when its off really, even after disable it keeping saying the same.
Ive already restored it, wipe everything in the device but Ive got still the issue going on.
Any ideas? Please I really need help

It might be a problem with your carrier. So, I suggest maybe trying to go into places where there is really strong signal and try there. Maybe reboot a couple times. If the problem still persists, then contact your carrier and ask if they have anything to do with it. Because, I almost guarantee that's the problem.

I've already tried it without success, and even called my carrier and they turned to me the network was fine.
I reckon is a problem with the fact that airplane mode is turning on and off automatically
I'm so annoyed with this don't know what to do really

can you try your sim in another phone? or another sim in your phone

I have already tried both options, neither of them worked.
So the problem is with my phone but I'm really in trouble since I haven't got the guaranty of this phone because I traded it for my old device.

Did you try a different kernel and / or radio?

What does your phone status show in settings? Baseband, Network, IMEI, etc?

Flash stock rom, delete superuser or supersu, and take it to your carrier to complain. If the problem persist on stock then it's really nothing you can fix. You should be able to get a new device.

The problem is that I havent got the guaranty since I trade this phone for another old one that I had. Hope there is way to repair it even if it cost money

Surprising this is... I just cane across this exact problem today. I just removed my SIM Card, put it back in, then rebooted. After a little while I got my signal back.

This happened to me last night. Took my phone off wifi realized I had no connection to my mobile network. Pretty frustrating, but flashed a couple different kernels and seemed to fix the issue.

[Q] Disable reboot after SIM disconnect

Currently even if disconnected at all - it will force a reboot if it the SIM isn't detected? I have xposed framework installed but I can't find a module which would do what I am describing.
Is there a way to disable the phone from restarting after it recognizes that the sim card had been disconnected?
Like a way for it to ignore that the SIM was disconnected or anything to do with that warning/force reboot message.
BTW what is up with the captchas? seriously? Has someone spammed the forum a whole bunch cause I swear every time I needed to enter one it took me like twenty times before it would verify! Indeed the hardest captchas I've ever tried to read!
Thanks for any help!

That's not normal behavior at all. First I would try to disable xposed, could be a module doing this. If not, then reflash stock firmware or clean flash your current rom

My phone also randomly loses detection of the simcard which obviously has not been removed because I doubt you can get it out with the battery and cover in the way, but when I was trying different roms, (sorry I don't remember which one off the top of my head, I think it may have been a rom by The Sickness or possibly Jamison904) one of them didn't care that my phone didn't detect my simcard, it obviously didn't make/receive calls, texts, or data while in this state till I reset the phone and the simcard was detected but I just wanted to let you know it is indeed possible.

Normal behaviour will not reboot it, I've seen that problem with a friend's phone and it never forced a reboot. That's why I suggested to disable xposed, reflash stock firmware, reflash rom, or flash another like you said

I assumed it was stock firmware that forced reboot when the sim was no longer detected, NOT an xposed module. I was wondering if there was an xposed module which could modify that behavior. Jesus can I donate money to get rid of the recaptcha?

Nope it doesn't do that, so it's unlikely that such a module exists. This is the first time I am reading about this behavior to be honest. I just use tapatalk so no captcha

I totally figured it was... it did NOT seem like the kinda message xposed would force on you....
Unless you meant that it could xposed causing a hiccup in the loop, but that's still ambiguous.
I doubt it's xposed as my phone was resetting constantly, got a new SIM and I've seen it only do it once since I put it in a week+ ago. Might try that first?
Edit:
Man this ****ing captcha is stupid. For a coder forum why should I have to enter it again after I hit preview post?!?!! I'm trying to write better, seriously anyone know any robots who spam and preview their posts first? Now I'm just gonna submit and edit the stuff which doesn't require a captcha to be entered..... which is REALLY dumb that I can do that cause spammers could just spam a bunch of regular posts then edit them en masse.

I still don't think it's stock problem, but try this, guys
I just came across a thread I remember reading about a while back and thought I'd share what their solution was.
Solution is below:
"I discovered there was an issue with the setting in the OS (Settings, More Networks, Mobile Networks, Network Mode) and the Service Mode settings (Phone dialer, *#2263#). *Service mode was initially set to Automatic and under the band preferences I had some other non standard settings. *I went thru and verified all the band settings were set to "all" and selected option 6 (LTE/WCDMA Mode) versus option 1 (Automatic). *I have not seen an error in over a week."

Hmph, that's crazy that is what caused the problem. I'll try it if it happens again and see if that works but changing the sim card seeems to have worked.
It was confusing because they mentioned all the button presses when you can get to the menu from what they said.

Yeah replacing sim should always be one of the first things to try in this situation. My friend has the same problem and turned out it was the sim card they were using was a cut one. This phone is not friendly with those

Edit: just realized the next setting is WCDMA/GSM only, no WCDMA/LTE only or do yo need to be in the service menu via the key presses?

LG G4 WiFi issues

Good evening all.
Has anyone with a G4 on VZW noticed issues with apps on wifi since the latest firmware update? I've called Verizon and been on the phone with them for HOURS to no avail.
The only time wifi works normally is in safe mode. When I'm on wifi, most apps just aren't functional at all. We thought it was some app in particular so we reset the phone and the issue persists. The only thing tech support suggests is giving me another refurbished G4 which will get us nowhere as the new G4 will just be running the same firmware.
This is problematic for me as I work in and out of different buildings on any given day. These buildings don't always provide the best reception. I clamored with Verizon for a different, comparable phone. I spoke with LG and their solution is me sending the phone in with the turnaround time being 5-7 business day which is also problematic as I don't have another phone to use. Verizon refuses to acknowledge it's an "issue" because it's not "wide spread". A quick search revealed that this problem is not limited to just me.
I've exhausted my options. I do not want to spend hours on the phone with Verizon again. I do not want to speak with LG for the same phone again. I simply want a working phone. This is the 3rd G4 that I've had that does not work. The 3rd G4 in almost as many months. What are my options here?
tl;dr This is my 3rd LG G4 that doesn't work and the latest firmware update broke the wifi functionality. Verizon refuses to acknowledge the issue and will only give me the same phone, not a comparable phone. What are my options?"

Yup. Since the update. Wifi on my phone is lagging horrendously.

Yes, since the update I don't get any notifications while connected to WiFi. My WiFi is slow anyway, so I haven't noticed any lag that others are reporting.

I spoke with them again today. Their only option is to send the same phone again which isn't going to fix anything unfortunately.

Same problem here (and also with friends who have both VZW and the G4). This exact issue popped up on the LG G3, also after an update. Infuriating that they broke another otherwise good phone. The workaround is to install an app called DNSet. It sets the DNS to Google's, which fixes it.

I am having the same issues. doesn't matter which Wi-Fi network I'm on, it is terrible. Otherwise I love the phone, but this is getting really frustrating

Yeah I'm having the same issue. It's maddening!! Nothing comes through unless I manually sync or have to open the app to get it to sync. How is this an acceptable software update for verizon - who usually requires a high level of quality control on software updates??

The Update broke Notifications over WiFi. It has something to do with IPv6. Verizon PULLED the update because this is a major problem.
Either call Verizon and have them replace the phone (you will get the older firmware 11A back on it)
OR
The fix is to download DDNS or something (It is a VPN service) that routes ALL internet traffic over IPv4 connections. I forget the specific name, but it is being heavily discussed in the "VERIZON UPDATE" forum in the General section.

Read the thread, I think toward the end more.
Almighty1 said:
Give this solution a shot, and what router (make/model) do you have exactly?
You can fix this issue without root by using the app DNSet from the Google Play store. You hit 1 button (the one and only button), and it turns off IPv6, and problem solved.

I had this exact same thing happen on my Sprint S5, but in the S5 days you werent able to completely flash another carriers firmware. The only thing that would stop that is having root access and freezing the app in titanium backup pro while on a touchwiz based ROM. Anyways, there are some non-root methods out there to freeze apps, but im not sure if thell work for system apps. Worth a shot IMO if its bugging you that badly.
