Wifi Bluetooth problem, phone restarting. - Sony Xperia L

I have been having this problem for quite some time, when I on wifi or Bluetooth (or both) the phone restarts for many times till it comes to a point where the wifi and Bluetooth is grayed out, I've reflashed the stock ROM, took it to service center but no luck. Please help.

That seems to me a lot like a hardware issue... Does it also happen when you turn on bluetooth (without WiFi)?

same problem here

That sound strange .
I have got a little idea about it I don't know if its related to this issue.
It could be due to the network related different b/w c2105 and c2104.
So are you sure that you flashed the suitable ftf for your device.

Vibration not working

My SGR has stopped vibrating, regardless of the setting. I noticed it about an hour ago.
I can confirm that it was working about 12 hours ago.
I am running InfectedROM V1 on ardatdat's keenal v1.5
Anybody got any ideas what is wrong?

I can't understand what could have caused this, did you bump /drop you handset anywhere recently ? If yes then it can be some hardware issue.
Check your recently installed apps, they maybe interfering with the vibrator settings though that's a remote possibility but do check.
If its a software bug then flashing the ROM/kernel again should solve the problem. But keep this as the last option if it seems there's no other way out.
It started working. On its own.
I had it in my pocket, got a text and it vibrated.
Funny issue. I can't understand what happened. But I am glad I don't have to take it in for servicing.

That's good !
I think it must be a software bug which caused it then.
It was solved as you may have restarted your handset but still do observe if it stops vibrating intermittently.
Actually I did a soft reset when I noticed it, that did not fix it.
I tried changing the vibration settings randomly and all but nothing worked.
I have got no idea what happened. But I have been checking the vibration every hour or so and it hasn't stopped working after that.
It has stopped vibrating again.
This is so irritating. I miss calls and texts because of this.

Darn !
That's why I told you to monitor it. Now I think it could be a software issue. If it was a hardware one then it shouldn't have started working again.
Check if a restart solves the issue. Do remove the battery for a few secs before switching it on again.
If it works its a software bug.
Did you check the installed apps if they are interfering with the settings ?
Do check the settings for Vibration intensity if they are at default.
Check and reply here buddy though I think you'll need to take it to the service center if even flashing stock ROM doesn't solve the issue.
I finally found out the problem and the solution. Was googling about it and a guy with SGS2 had posted on some forums that his vibration stops working after removing headphones. He also gave a solution to change the vibration settings to 'never' and back.
I tried that but it didn't work.
Then I tried replugging my earphones and the vibration immediately started working.
I don't understand what could be causing this issue but atleast I got a fix now.
Seems software related as you said. Maybe it is fault with either the customROM or the custom kernel. Would be pretty weird to have bugs like this in stock.

There are no such bugs on Samsung stock ROM.
You'll need to request #ardatdat & #eaglerazor12 to look into the issue and they will definitely help you.
It has stopped wirking, yet again and no matter what, I can't revive it.
I have even flashed everything stock except for the recovery. [Is there anyway to go back to stock recovery?]

I reflashed my nandroid backup through CWM to get stock back. Should I flash it again through Odin?
Sent from my GT-I9103 using XDA App
actually no, but if you have your fw u may take recovery from the package and push it to another tar file (use total commander) and then just flash it via odin.

This fixes the problem.
I feel really angry at Samsung for making the SGR with the same fault that SGS2 had. Why not fix it if the already had complaints about it in the previous phone?
Atleast I don't have to take it to the service center now.

[Q] Wifi keeps dropping on Xperia J

After the JB update (to 4.1.1.), wifi keeps dropping, in the sense that I can still see the wifi signal on the status bar, is not grey, but no data packages are sent/received. What is weird is that many times I can get the wifi to work again by locking and then unlocking the screen, even though I have the wifi sleep policy set to never. Having it dropping all the time was a big annoyance, so I tried the tips regarding wi-fi routers settings (on 2 different connections) and different wi-fi settings (like having auto IP support on and avoid weak connections off, with stamina mode also off). Nothing changed.
I have done countless factory resets and software reinstalls through PC Companion and SUS and nothing changed, so I took it to the repair center where they downgraded my phone to ICS. Even though before my JB update my wi-fi worked like magic, now with ICS the wifi keeps dropping. I have done other factory resets and software reinstalls before updating my phone to the latest JB (4.1.2.). Again, no improvements.
What else can I do, besides rooting? Can it be a hardware issue?
Same,but you can get 4.1.1,what firmware name?

Actually, I've checked and it seems I have tried the 11.0.A.7.5 firmware (ICS) and 11.2.A.0.21 and 11.2.A.0.31 (JB 4.1.2.).
sounds lika a hardware problem bro. If it was software problem then it would be a module problem which would be fixed by reflashing the kernel which is where the wifi modules are written. Do you have a ST26a or ST26i.

A ST26i (the global version of the phone). Thank you so much for your answer. So, the reflashing of the kernel is what happened when I reinstalled the software? The question sounds silly, but I'm a noob...
Also, I'm a girl...
Thank you again!

Yes thats why i think its a hardware problem flashing the firmware reflashes the kernel aswel so if it does not work after that then you will have to send it for repair.

Thanks for your explanation...now I hope the guys from the service will understand this issue...last time they only downgraded the software and overlooked the touchscreen issue for which I have sent them the phone (I had to send it again for repair afterwards).

It lagged really, really bad, making it unusable at times - so that was the second issue for which I have sent it at the service despite the wi-fi problem. After they have downgraded the software and the problem with the touchscreen persisted, I insisted to have them look to the phone a second time and they discovered they had to change the touchscreen. So that one is solved. The wi-fi issue I described remained Guess I'll pay them another visit....

If it is the wifi chip it can not be fixed as it is just a small chip on the motherboard i don't think it can be fixed. is it still under warranty.

Hi experts,
I have downloaded the OTA from Verizon. Please find the attached picture of my Phone, to know the Technical information
MY Problem :
When, I'm not using my Phone, even though, I'm at home and I have WiFi at home, My phone is disconnecting from the WiFi and using the Cll 4G LTE Signal, after I lock my phone screen.
This is the 3rd month in a row, I'm paying insane charges for the Data. Did anyone found a solution for the problem??
Thank You.

Sorry. I can't even think of what would cause this. The only thing I can suggest is try a factory reset. Don't restore any apps. see if it happens. If it does then odin stock 4.3, and try again.

[Q] Data once lost wont re-connect

i am currently using Resurrection Remix 5.0.2 but was using cm12 nightlys before. The problem is that
the data connection is good but once i loose the connection there is an exclamation mark next to the
signal bar so i presume thats the data lost. It then wont connect again untill i reboot the phone.I have tried
switching on and off data but still no joy..This never happened on kitkat. I thought the problem was CM
related hence why i tried the RR rom but exactly the same is happening. Someone sugested that it could be
the sim card but im not so sure as it works fine before lollipop.I surely can't be the only one experiencing
this? but by the same token i can't find any info on it either ..maybe says something!!
Hope someone can help as i want to stay on lollipop i do like it, maybe the official release will sort it out.
Thank you

It's a ROM issue (radio.img). I was facing same problem on earlier builds of BlissPop ROM, but not no issues..
If you are getting exclamation mark in 2 or more ROMs, then there is problem with your sim-card or the network operator.
I suggest you to contact your concerned network operator and take his help for the same. (If you are facing same issue on 2 or more ROMs, try out Stock ROM CM11s)
Thank you for your reply, so would it be possible to flash a modem from kitkat or would there be compatibility issues with that?

did you check your network type and apn settings
So here is the latest update. I replaced the sim card on Saturday, the problem is is still there. I checked me APN settings they are three UK so that's ok. I've tried cm12,resurrection, blispop and now I'm on sabermod. I'm thinking this oneplus doesn't like lollipop, looks like I will have to revert to kitkat for just now until the official release comes out but I can't see that fixing the problem either as I don't seem to see anyone else with this problem.
Thank you for your help folks

I'm also with Three and have lost my data connection. They replaced the sim on Tuesday and I'm sure it worked until the old number swapped to the new sim. I have a 321 simcard on order and I'll try that once it arrives. My phone is still running Kitkat.
I had no problems with kitkat, if it lost the connection it automatically connected again when I was back in an area with a signal. But this has got me beat, a new sim card and too many roms to count but still the same problem. I am a lorry driver and cover the whole of Scotland and signal is patchy at best and it's annoying to find out later on in the day that data was off and you didn't receive any messages or emails.. Some of them important..

I have exactly the same problem.
I'm from Spain.
I've discovered that if i set network type to LTE it seems to work right.
Today I've moved from blisspop to temasek.
The 3g reconnect doesn't work, as always.
I turn data and wifi off when I sleep so tomorrow I will confirm if LTE works also with temasek.
my connection has always been set on LTE but never makes any difference
At the weekend I installed the official OxygenOs, I have been driving all day and had to reboot the phone 4 times because of this problem, I did half wish that when an official release came it would maybe sort out the problem but no joy. So I can only think it's to do with the oneplus. I'm at a loss now and seriously don't want to go back to kitkat but it looks like this will be the only solution to the problem..

I've tested this night again and if I set network to LTE.
The test I've done is.
- Turn off data and wifi before to sleep.
- Turn off only data when I woke up.
The connection was successful almost inmediately.
Greetings. I ran into similar issue with the CM12s update.
Once I lose the mobile signal for whatever reason, the data connection is not restored. Only way to regain it, is by restarting the phone (haven't tested airplane mode). Sometimes even if I leave WiFi on for long time (overnight), I will not have data connection after turning off the WiFi. I use HSPA connection only, not LTE.
I can not recall having this issue on KitKat. Issue was on the first CM12s update and remains on the second one, both were installed clean, so clean install of the ROM will not fix it. I am not using any custom ROMs or kernels, only TWRP recovery.
Has anyone had such issue and maybe found a solution to this?

Did you ever get this sorted? I've been having this issue, luckily I always have Wi-Fi at home/uni but there are times when it just won't find a Data connection. This happened right after the CM12 update :/

Well decided to a bit of searching, if you go into Settings -> Mobile Network Settings -> Network Operators and manually choose the network rather than the Auto Search option, it seems to have worked for me for the time being.
I am on the same boat as OP. The problems started after updating to Lollipop.
If anyone has found a solution, please let me know. I read about someone installing a 44S modem, but I'm unsure if this will permanently change system files (I wouldn't want it to) and I'm therefore hesitant.

Nexus 5 stuck on "Turning wifi on"

Hello all, my old Nexus 5's wifi stopped working back in January for no apparent reason. Everytime I tried turning it on for some strange reason it just Grey's out. The MAC Address is also really weird. I tried looking for a solution but to no avail. I'm starting to think that it's a hardware issue. These are what I've done so far for the past 4 months or so:
- rebooted the phone
- wiped the cache
- wiped data using TWRP
- letting the battery drain and charging it again after a couple weeks
- smacking the back side on my hand (lightly of course)
Any help would be much appreciated. Also, it's not my primary phone anymore so I can't tell whether cellular connection would be working or not.
Just did a factory reset and wiped everything, still nothing. MAC Address is just a solid 2.00.000.00. Also, Bluetooth still works.
Try running a stock 4.4 or 5.01 rom. If the problem still exists, I'd say it's a hardware issue.

Hmm, I had a similar problem few months ago, tried flashing the latest stock firmware; didn't help and then moved back to a custom ROM. Strangely, it didn't work at that time too but kept the phone the same for an hour and out of nowhere it started working. Seems like the phone is really dying now.

Still doesn't work for me. I'm gonna try taking apart the phone to see if the wifi chip is ok, hopefully it's not a hardware issue.
Same problem here, even on custom ROMs and factory images,
Is there any hardware solution? Maybe an external WiFi antenna or something like that?

Not that I know of unfortunately. Guess we'll have to buy a new Mobo for the phone
Hi guys! Since today I hopped on the "activating wifi" train too!
I'm on Lineage 14.1 CAF, and did a full wipe and flash, no changes.
I followed a guide in a post here on XDA to recreate the MAC address file, after that wifi worked for a couple of minutes, then went down again.
I thought about flashing MM stock image, but after reading your posts I think i'll keep my phone this way until I buy an OP6.
Luckily I have 15Gb of cellular data
What I did was I opened the phone and took out the motherboard and disconnected the battery from everything, then took out the heatsink that's on top of the wifi chip. It worked for a bit then it stopped working for good. It definitely has to be a software issue because Bluetooth is working fine.
It could be a hardware problem. I have two Nexus 5 motherboards where the wifi tries to turn on and, eventually, the slider goes back to the off position.

Damn, I guess I'll have to change the motherboard to get it working again. I might just sell it as is or for parts since it hasn't been my main phone for a while. But I did want to give it to my nephew...

MY Nexus5 got the same problem 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 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 from ubports

Hi guys i have tested as mentioned before and reinstalled stock room after installing ubuntu my WiFi is working again perfectly :fingers-crossed::fingers-crossed: . Who has the problem of this kind should try doing this method it will reinsert or reset the mac address and get rid of the problem of the mac address of 2.00.00.00.00. and your original mac address will be restored. It worked for me hope it can help you also
