[Q] Wi-Fi problem . - LG Optimus G Pro

I bought my LG F20K in May and I was very happy with it since.
Worked as a charm and didn’t have any problems with it. Till last Tuesday.
I came back from holiday and unfortunately Wi-Fi in my phone stopped working.
No any symptoms or signs of problem before, just it didn’t connect once with Bluetooth in my car, that’s all.
After return home, any attempt of switching on Wi-Fi made phone frozen and warm back, sometimes it restarted itself but it didn’t see any Wi-Fi network. When I tried switch on Wi-Fi with Bluetooth together phone got completely frozen but Bluetooth itself works fine.
First I decided to restore factory settings. So I did. It didn’t help. After research on internet I decided to do it again ( factory settings) but by LG Mobile support Tool on computer .Unfortunately it didn’t help too … I wrote to seller who I bought phone from and He agreed to take phone from me and repair it . But He is in Korea and before I send it I try last attempt on this forum.
And now the most funny thing.
Yesterday evening I left phone with charger on for all night and today morning with cable charger still on I checked if maybe something changed regarding Wi-Fi (you know… I got habit to check it every few hours with stupid hope it will repair itself …) and it did! Phone discovered Wi-Fi network and after about 10 minutes of attempts connected to it!!! . However – Connection was very unstable and I had to manually connect it many times tostay connected. My happiness didn’t last long . After about 4 hours phone lost any interest to connect with Wi-Fi or even to see it …Now I hope it is just software bug and I could repair it somehow.
Any ideas about it? Did somebody tackle with similar problem? Maybe if I rooted phone it would help?
Software version in my phone is F240K10r .

Connecting to pc killing wifi network

Hiya i hope someone can help, i took delivery of my MDA compact 3 yesterday to replace my aging blue angel. Everything went well until i connected it up to the computer. I already have active sync 4.5 installed for my previous phone. But as soon as i connect the phone via usb to the computer it kills my wifi connection. I have to then re boot the machine to get it running again, im 99% sure this is down to the actual phone as my blue angel has worked for years without this problem. Is there a setting that ive missed?, ive spent hours trying to figure this out now, the phone for some reason appears on my network connections (never happend on old one), ive disabled the network setting but it still kills my net..... aggghhh lol
thanks in advance for any help.

thanks for that, sorry for the late reply not been online. Anyways ive tried that and its still doing the same thing, ive now started to sync with bluetooth as this solves the problem but not ideal.
Update...... I just loaded wm6 from tmobile website hoping this may solve the problem. I tried that walk thru again and no dice. I kept losing all my internet connections. SO i had a play with the phone and in the settings menu i found a USB to PC icon. I opened that up and UNTICKED "Enable advance network functionality". Pluged the phone again in the usb slot and away she went, all my connections are still live!! yipee.
Hope this helps a fellow member out in the future.
thanks

GSM not working anymore, stuck in emergency mode

Hello all,
my Defy is stuck in emergency mode and can't find my carrier anymore (o2). Details:
- only emergency calls possible, no network found
- another mobile in my house gets outstanding connection (o2 aswell), when switching SIMs, it's still my Defy not getting a connection
- wiping the Defy has not changed anything, even with stock settings all I see is the red cross (put my settings back with clockwork recovery)
- an hour or two before this happened I was listening to music with my headphones, but between taking the headphones out and GSM failing I was sending texts
- When doing a search for other carriers I can see some (though not reliably), but not mine
- I bought my Defy via Amazon, so no SIMlock, obviously.
- WiFi, Bluetooth and GPS are all working fine, so they probably have different antennae
- I rooted my Defy, but this was over a month ago, and it was working fine. I also did not install apps or update some existing ones before this happened. I also did not reboot. It just happened. Put it in my pocket and next time I got it out there was the red cross.
In Phone Info -> Status it says under signal strength "-111 dBm 1APU". It all looks like the antenna is broken, but I didn't hit it, drop it, put it into water or hurt it in any way before this happened or the 3-4 days before. So I'm really lost here.
Anyone? Thanks in advance.
Hi. Have the defy for about a month now. Same issue since first day. Dont know whats wrong. Found out that after 4-5 reboots its ok and lasts till next reboot/switch off. So try turn it on/off 4-5 time or just download a quick reboot app and do the same to see what happens. If aneyone has any idea on how to fix this?
i get this all the time when i flash my defy thru any other rom......and thus roll back every time to stock (indian) rom.....
try flashing your phone with any compatible rom....new radios might get ure phone working
Same problem here. First time today, spontaneous, after a month of use my Defy, non rooted, never unlocked, standard noMOTOBLUR, just like as it was bought from store. Moto_Versiuo.2.34.1.MB525.Retail.en.SEA
None of these worked to restablish the radio connection: succesive reboot, manual/automatic network search and choose, succesive airplane on/off. I didn't check the signal parameters.
I thought that the SIM just burned, removed and try it on another phone and everything was OK. When put it back in Defy, the network connection was established.
The experience was very strange and my final verdict was that the SIM just moved a little from its initial position.
BUT now I realize the problem is more complex and I don't know what caused it !
I have also noticed that the sim card slot gives a little more space for the simcard to move (at least on my defy). Might be a prob with the sim card being old or something (mine is from 2005). For now i'll just try to keep my phone on (seems i finally found stable settings for setvsel, so no more unexpected reboots).
An answer from motorola's official support forum is just remove the simcard and clean it with some cloth...
This is definitely a sim slot/card problem. If bought from amazon they will oblige to change it without any money. I did the same but not for this problem.
If you think there is some problem with software, which is unlikely then flash an sbf and see if things are fine.
To begin with flash chinese froyo sbf. It is downgradable to any previous firmware you were using and very flexible.
Hope this can solve your problem. Get back on what the result is.
Same here...
My defy got network yesterday at 07pm til mid-night.
before, since 16 (11pm) til 19 (7pm) before it function again.
and now, its bloked.
i rooted my cell one month ago, then, probably thats not the fault of z4root.
Sorry about my badass english, i still in upgrade mode.
any idea about it guys ?
thnx

Problem solved replacing sim card with a new.

[Q] suddenly can't see any mobile networks - Baseband "unknown"

SYMPTOM: can't see any mobile networks
BACKGROUND: I've been using htc one x for a month now. Initially on three, but their signal was unusable at home, so sim-unlocked and switched a couple of weeks ago to giffgaff ( a virtual network on top of the UK o2 network).
All has been fine, until today. I sent a few texts & calls in the morning, and mobile data was working. Since then, I can't see any mobile network.
wifi is fine.
Search Networks pops up "Error while searching for networks" and finds none.
No software changes of any sort since last successful call. No changes at all today, at least until I tried to diagnose the problem.
Running stock rom, with the WW update of a couple of weeks ago (1.28.771.9.CL56522 release-keys) -- neither S-OFF nor unlocked bootloader.
Nothing obvious to me in the normal or radio logcat logs.
The only thing I did after the last successful call was to run sensorly to try and map a trip. I've used this before without any problems. It got no connection but I thought nothing of that. I've since uninstalled it just in case it could somehow be interfering with the radio.
THINGS I'VE TRIED:
No, the airplane mode isn't on, and mobile is. I've toggled airplane from settings and power switch, many times
recreated the APN
checked other phones - yes there are a number of networks visible
tried the original o2 sim - same problem
safe mode
cold boot
reboot, reboot, reboot
obviously I haven't pulled the battery...
turned off wifi, in case it was somehow interfering
HTC diagnostic tool
factory reset
confirmed imei is not blocked
Any ideas? Bearing in mind that I'm looking for something which can happen spontaneously.
Interestingly, while writing this I've just noticed that Baseband version shows as Unknown. That worries me - is it possible that my radio partition has spontaneously corrupted itself?
I did speak to 02 support - they said to take it into a shop for warranty repair. I don't want to try a custom ROM just yet -- not when I might have to use the warranty. But is there any way to force it to reinstall the stock rom (preferably not involving windows)?
I have the same problem as well and flashing custom roms did not solve it for me. But for me even the IMEI number is shown as UNKNOWN...I haven't done anything special to get this issue, one day when I woke up the phone could not connect to any network.
I have tried a lot of different methods but with no success. I don't think we can do anything about the baseband without S-OFF.
If a hard reset fails, then it's time to think about returning the unit. Either get a refund or get it replaced.
This may be irrelevant; but I've had this happen to me on my GNexus. I solved it by going back to stock and it just fixed itself overnight.....
my HTC One X did the same after about 2 weeks. Gave it back to supplier, waiting my replacement.
Even tested with a different SIM card, did a hard reset. Problem stayed the same.
Im curious did any of you find a resolution to this? it happened to me a while ago but yet to fing a solution. HTC refuse to fix under warranty because it is unlocked.. i am currently waiting for the next official update to see if that fixes anything but the way things are looking that could be a while..

It sounds like a fault, probably the radio chip has just stopped working, no software is going to repair that. If it was a software problem, there would be hundreds or thousands of people all having the same issue.

My Lumia 900 is rebooting on its own

Hey all,
Please bear with me
Here's the thing:
I got my factory unlocked Lumia 900 back in June from Amazon US... I'm really happy with the phone... no issues whatsoever.
My last update was about 3 weeks ago (forced through Zune {plug phone then disconnect from internet} to 8779.
On Thursday (Sep 20th), Zune suggested that a new update was available... So I did the update. I'm not sure there was any changes, but the firmware is still 8779.
On that same Thursday (after the update), I decided to convert from hotmail.com to outlook.com... So i had to reset (to factory settings) the phone.
After a couple of hourse, all apps (that were installed) were reinstalled and all accounts were created, linked... (in other terms, the phone was back to the same state... but with the outlook.com sign in)
Since then, my phone is rebooting on its own. It restarted once on Thursday, a couple of times on Friday... But on Saturday, It has rebooted more than 20 times already (many times when I'm not even using it).
- Since it worked fine for 3-4 months... I'm sure it's not a hardware problem... (and I'm not a US resident... so an exchange is not an easy option).
- Did anyone experience anything like that?
- If you have any advise/suggestion, please help me... anything!
Sorry for the long thread.
Thank you.
You should probably try the hard reset again. Sometimes when my phone is connected to the car or wall charger or any other type of charger and I try to reset it it will keep rebooting until I disconnect it, then it can reboot normally. Hopefully that helps or gives you some ideas.

If all that fails, and you really don't want to try to exchange it under warranty, there's always the Nokia Care Suite. You can flash the Stock OEM ROM to the phone agian. It has helped Some people get their phones working normal again. If it is NOT a hardware issue, and you sent in for warranty, this is exactly what Nokia would do to it, then send it back to you. I Highly suggest you download the LATEST ROM shown in the Care Suite, don't use the ones I've left links for. They are not the latest. Using the care suite, find the ROM that matches your Product Code.
Thank you for the reply.
Actually, I re-did a hard reset on Sunday and all is working great now
So if someone is having a similar issue, a hard reset would solve it

Phone reboots during calls

Hi guys,
I am experiencing a bug on my Swift where the phone reboots itself during almost all calls after a minute or so. When the phone comes back on, there is no record of the call in the call log! The phone does not reboot during any other activities. Phone details below:
Wileyfox Swift
Cyanogen OS 12.1.1-YOG7DAS2FI
Kernel version 3.10.49
Build Number LMY48Y
I have checked for another similar thread without any luck. Thanks!
I have a similar,though not identical issue. Phone keeps rebooting,seemingly at random,every other day or so. During a call, listening to spotify,idle on the desk...i have an untampered with original Os on the phone.
Cheers,
Me too.
Hi, I just registered to say I'm having the same problem. If you check the Amazon UK reviews too there are several people with this rebooting problem.
So far I have:
- uninstalled all additional apps I installed
- tried it with wifi and data off
- tried the other SIM slot
- done a factory reset
and it still reboots during calls. After the factory reset things appeared to work better in general (alarms now worked properly, and there were more options available, eg in the power button menu), but it rebooted 5 seconds into a phone call, which is a record. It's usually a few minutes into it.
The factory reset didn't actually delete my data (photos, files, etc), so I am going to do a reinstall via Fastboot now; firstly because I'll have to do that I guess if I want to send it back, and secondly to see if it finally fixes it.
I personally think the update process has screwed something up. It did an update as soon as it was powered on for the first time (it to 12.1), then a couple of weeks ago did another update to 12.1.1. It was rebooting before 12.1.1, so it is either 12.1 or earlier where the problem exists.
If it still reboots after a Fastboot reinstall then it's getting send back, and I probably won't ask for another. It's a nice phone, and a nice idea but I can't have a phone that reboots during >50% of calls. That's useless.
Pretty sure you can discount the update process too! I have also had this issue on cyanogenmod nightlies, I honestly thought I had inadvertently pushed the power button..but, NO
*edit* CM13 nightlies
That's strange as I have had no such problem with mine (bought in October) and mine is rooted with the unofficial builds of CM13... Maybe it is a manufacturing error and only on some devices...
Have you tried contacting Wileyfox?
I have not experienced this yet on the Swift when making or taking calls on it.
i'm on the latest cm13 nightly for crackling. each and every time the phone is called, whichever sim, the phone reboots. what a waste...
I have the same issue of spontaneous reboots, mostly during calls but also at other times. Spoke to Wileyfox who weren't very helpful. Has anyone found a solution for this?
Hi, I'm having the very same issue (appears a few are on other forums). Has anyone found a solution? I'm about to factory reset if it continues
Update
Hi guys, so i returned my phone for repair, and they gave me a new phone. Must have been a hardware fault I assume

Hi thanks for the update, I've just factory reset, if problem persists I'll try to get a replacement too! Was it quite a quick replacement process?

I'm in South Africa and have the same problem. Whenever sound is involved, I get random reboots. Calls, and music/audio books.
Not with videos though.
It doesn't reset any other time except when I've been listening to music, or on a call.
Been doing this from the beginning.
I thought it was Google Play Music, so downloaded different player.. That made it much less frequent, but then it started affecting my calls as well.
Not happy.
Hi, UK user here. I got this phone less than a week ago and have already had this issue a few times. Two spontaneous reboots on resuming from sleep, being connected to a large WiFi network was the only change from normal use here; then twice regarding calls, once when answering then immediately after reboot it rebooted again while the missed call notification was present, although still on the aforementioned large WiFi network. Unmodified, unrooted, Cyanogen OS 6.0.1 with two sims in use.
Same issue on my a1g2.
It reboots on wf swift Roms. It stucks in call screen on a1g2 stock rom. Strange...
i am having same issue, i make any call and mobile Soft Reboots itself.
So, much annoying cannot make a single call on this WileyFox Swift mobile phone.
Making calls is the main basic purpose of every mobile, but this phone just does not let me make a single call.
.Had this issue on Cyanogen OS 5.1. Now updated to Cynogen OS 6.0.1 having same issue. I have done phone setting HARD RESET and Clean Wipe 2-3 times. Still no solution.

Maybe it's the Dialer in Cyanogen OS, i installed the Google Dialer and made it default Dialer on my Swift, i don't have any problems with reboots during calls and i make long phonecalls. You don't need root access for this.
Although Wileyfox accept that there is a grounds for returns, I believe it is a software bug in Cyanogen OS 13. This fits in with using another dialler. You could also downgrade, or switch to Cyanogenmod.
Also, I only have found the issue when receiving calls, rather than making them, although I don't use a lot of minutes.
Sent bug reports to Wileyfox.. They're saying that what they see is a battery-pull reboot..
I tell them it's happening while I'm using the phone (music or calls)..
They say they can't see what the issue is.
Cos I'm in South Africa, sending the phone overseas is pointless.
Can anyone confirm that the Google dialer does cure a phone that does the reboots during calls ?
Just got a replacement swift from Amazon after Wilyefox service department had my phone since 16th of June. Amazon argued my case and in the end just sent one to me. !
Set phone up on wifi for my wife to use then put in the Voda UK sim, checked the APN setting were OK then tried making a few calls between our phones. first reboot was after 20 seconds or so and then after various tests it rebooted 4 or 5 times at which point I gave up for the night..
Any help appreciated or do I just give up now and throw in the towel, bought original swift in late May and never managed to make it work properly !!
Thanks

Well I've given up !!!
A second Swift was supplied with the help of a Amazon Rep.
We even got a £25 Amazon gift card from Wileyfox direct for all the trouble !
Set phone up on wifi, added all apps required by my wife. Put Vodafone SIM in and ...... Shutting down message.
Restarted phone and it did it a few more times. Ordered a replacement 4G SIM in case there was a problem with the 3G SIM we had. Activated new SIM and fitted it, worked for ten minutes then rebooted itself.
SIM is fine in any other phones I've tried.
Just about to return phone to Amazon, checked and my original swift is still sat with the engineer (since 16th June !!) according to the repair company website.
I feel sorry for anyone wanting their phones repairing after what I've been through.
