ST27i lost phone signal - Sony Xperia P, U, Sola, Go

Hi,
I wonder if anyone has solved this before. My St27i had been working great for some time using this ROM CM12
Last weekend though it just lost signal, when I tried to browse web using lightning brower in a bad signal area, since then whatever I have tried has not been able to get signal back...
I have tried:
- Completely re-flashing the boot and ROM images.
- Flashing this ROM instead CM11
- Deleting all the APN's and restoring them from default settings.
- The SIM card works fine in another phone.
- Wireless works okay from the phone with no signal.
Quite frustrating.
Thanks for any tips!

My Go only works on GSM. Are you set to the wrong network?

This kind of problem has happened to me twice on two different Sony (Ericsson) phones: first on a SE G700 and the second time on an Xperia P.
On both these the phone suddenly stopped being able to connect to 3G networks. I'm guessing both were equipped with chipsets produced by Ericsson and suffered from a design flaw.
The G700 simply could not see any 3G networks. I tried replacing the antenna assembly but it didn't work.
The Xperia P would reboot as soon as it tried to connect and I solved this by locking it to GSM/Edge in engineering mode.

[Q] Data Connection bug. How to solve?

The Edge symbol in my Galaxy S2 disappears when the signal is down.
It never reappear when the network signal get back. Even If i change all settings... tried disable/enable "Use packet Data" and other settings...
NO USE! It seemed to be serious and consistent bug.
Hi balavj, maybe a silly question, but are you sure that you are in an area well covered by edge gprs signal?

Signal drops inside a room... when i come out of a room... network signal regains... everything works... data connection symbol does not come back... this is the exact problem... only after reboot... it resolves
Ah I see... Never met these conditions with my phone here, so sorry I can't be of much help.

i am having a similar problem, seems to have happened quite recently for me as previously i had no real issues with it at all.
I keep having to reboot my phone to get a mobile network connection, otherwise the Mobile Network Status shows as connecting all the time...
Very strange
Try other modem, or shove the phone into airplane mode and back again should kick it back onto data.
I have the same problem here...
Tried KE4 (Original), KG7 and KH3 modems e nothing..
Tried many roms too, and nothing, the problem is on all of them...
Data on/off, Airplane mode on/off, nothing gets data working back, only reboot...
Ps.: ROMs tested: Lite'ning, Cognition, Exynos, KE4, KG7.
Kernels: Niphetamine, Jeffrey, Speedmod
SAme here
same here...
Is anyone still experiencing this?
I was having major issues with connectivity, data and calls. I got to the point where i could barely make or receive a call or connect to a mobile data network.
I tried numerous modems and firmware, including original O2 carrier branded firmware, generic firmware and custome ROMs. I found the problem replicating across them all.
I finally settled on Crsikelos ROM (V14) with KE7 modem, however i had previously done a full wipe install of my original O2 firmware (XWKDE i think) and tried a couple of different modems (KH3, KE2 and KE7).
I even tried removing my SD card as i am convinced my sd card is not compatible and is causing issues...
All of a sudden everything started to work again?? I put my SD card back in and left it in, no chance everything was still working. So then i flashed Criskelos Rom and made sure my modem was KE7, that was about a week ago and it's still all good.
TBH i think it may be something to do with O2's network being pants (rather than my SD card )....
Not sure this will help but i thought i'd post my experience for you...
Hope you get it fixed
i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.

Can't find any WiFi networks when searching

Hi there!
So, I have a little problem with my second phone. The problem now is that I can't find any WiFi networks when I search for one. I have always had connection here home, and it works fine on my XS.
I don't want to restore or flash anything because the reason I need WiFi is to back up the bookmarks I got on the Dolphin Browser that is installed on the phone.
I also want to say that I don't have any SIM-card in the phone because I'm using that one in my XS, but that should not affect WiFi as far as I know.
I'm running Android 2.3.3 and baseband 2.1.71.
So what could the problem be?
Thanks in advance!
What rom have you installed, if so, do you have the right kernel and wifi modules? any details of what you have installed?
Are other pc's or mobiles at home able to perform a search for wifi networks and see the SSID of the router?
Upps.. sorry for leak of info.
I'm running stock ROM. Yeah, I have the right kernel and WiFi modules. The phone have worked well before.
Yes. This phone is the only one who can't find any WiFi networks. It sucks! Never had this issue before.
I am having the same issue. Just started the other day. My phone will not find a wifi network unless it is sitting next to the router. If I am over 5 feet away it just says searching and not in range.
Any thoughts?
Okay, just stood 1 meter from the router, still it didn't find any wifi connections!
This sucks!
When you go to wifi settings and activate it, does the tick apply to the box(enabled) or does not do anything?
It doesn't sound nice. if you are sure that you are running Sony ericsson original software (no custom roms, kernel and else) then try to do a factory reset from the menu, if it doesn't do anything then use SEUS and reinstall the software.
This will prove that this is either or not a hardware fault. It is the best way to check. If it still doesn't work after SEUS reinstall, then it is definitely a fault. If it fixes it then congrats..
If it's a custom rom from here then forget seus and flash the rom again.
Screenshots are welcome if you have..(wifi settings, system info..)
Good luck
The tick apply to the box yes.
Okay, so I connected it to my PC and ran Update Service and did a fresh reinstall of the software. Still the same problem. Can't find any WiFi connections
Well you already know the answer..
Yeah I do.. Think I'm going back to the store with it and get it fixed. Also have some reboots problem that may be related to this..
Thanks for answer.
If you only need your bookmarks just put sim from XS in X10 and turn on and backup info and replace sim in XS.
EDIT: do you have unlocked bootloader? If yes u can try relocking it.

hello mister, I have a same issue with you.
my LWW cannot find a network althought I was sitting in front of the router and it says not in range.
but sometimes it can works well, but it often cannot work
still searching for the solutions
Think its the wifi antenna thats failing.
First I couldnt find any WiFi networks. I had it off for a few weeks (got my Xperia S xD) and when I tried it, it worked well.
So its not easy to find the solution for this.. It sounds like a hardware issue
Sry m8.

Xperia U: very weird wifi problem

My girlfriends XU is acting up ultimately weird..
Since some time we have this problem:
Wi-Fi only works for about 3 minutes when connecting to a wifi signal, yet the wifi signal icon indicates as if it has a good connection. The only way to regain connection again is to reboot, but then the same problem repeats itself, after a few minutes wi-fi is not working anymore. Also in the wifi-indicator the "send" arrow works, the "receive" arrow doesn't.
Basically if you want to discover a new wi-fi connection you need to reboot the phone also, because otherwise the previous connected wi-fi signal remains (it freezes as stated before after about 3 minutes).
Tried a factory reset already.. Didn't work. The phone runs the stock sony android 4.0.4.
Any idea's ?

Does it happen with all routers or only with your router?
Have you tried to repair using SUS?
Someone one the official forum had a similar problem and it was fixed by repairing the phone using SUS.

LTE/Mobile Data problems

I've been having some issues that i wasn't having before. I've got the OPX for about a month now and it is connected through LTE but i can't access internet.
If i turn airplane mode on and then off, it works for about a minute or so, then stops to work.
Anyone experiencing this?
Everything is ok here no problem yet
Sent from my ONE E1003 using Tapatalk
check apn's
APNs are there and they are well defined, I have manually redefined them now -> Airplane Mode on -> wait a few seconds -> Airplane mode Off -> surfed reddit for a minute or two, all of a sudden "This page cannot be displayed: 'ERR_TIMED_OUT' "
I would think this is a network problem, but there is a forum thread in oneplus forums where people are complaining about the same as me, although they associate the problem to Wifi and i don't
Also, i don't know if it's related, but I've flashed the latest version from MasterAwesome, the problems started there, i thought it was from the ROM, so i then flashed OOS2.1.3-x, where i had the same problem, then 2.1.2 and still the same issue...
I'm getting something like that issue but very rarely and mostly on WiFi. It comes between sleep and awake states so maybe check out greenify and see if that is the culprit. Or any other app that's restricting any function through the waking of the phone.
My oneplus x detects wifi very well, but does not connect to mobile data. What could be the problem?
Uh I have a similar issue but usually when I'm in motion. (in guessing switching between cell towers) what's your network. I'm using Tmobile US

Same problem I had yesterday. Must have tried 10 ROM's all of them flashed fine and everything worked except cellular data. I had no data what so ever. As soon as I flashed back to stock ROM data worked fine. So there must be a step or something we've missed in flashing custom ROM's spent all day yesterday trying to figure it out with no luck. Finally gave up and went back to stock. I'll wait for the official OTA marshmallow update from Oneplus
I'm having this issue right now with full 100% stock. Does any of you have the problem solved?
Just wiped data + cache + factory reset, but still no luck. I've also created a ticket on OnePlus support.

Are you using 2 SIMs? Data does not work for me on SIM 2 Slot but works fine on SIM 1.
I also can't connect to mobile data. There is no LATE/4G icon in the status bar but if I pull down the notification panel, LTE appears above the network icon. I've tried in both SIM slots. None of them work. The SIM card works fine on other phones.

Did you tried an other SIM? Change Sim location?
Did you reset APNs in the back up menu?

Yeah, I've tried 2 other working SIMs and I've deleted/resetted APNs, even manually configured them (copied from my other phone).
Maybe you lost the IMEI. Try to find it with *#*#4636*#*#

I flashed the stock rom and it's working! I will try it for a few days to see if it's a permanent fix.
Android N, same issue with all ROMs.. tried everything, no luck lte doesn't work at all.
Hi!
I did rooted my phone and unfortunatelly there is one problem...I lost my data connection. I have wifi and I can make calls but mobile data is just not working at all.
I have tried some methods...restart, sim out and back and restart, manually pick the provider and restart etc... nothing works.
I did not flashed any ROM but using stock so its wierd.
Any suggestion for a solution how to get back my mobile internet connection?
Thank you in advance,

internet connection problem with Sony z1 compact

Hello,
I,ve got that problem with my z1c for a long time. In fact, since i own this device.
It has a problem with connecting to the internet, lets say, every fifth attempt to connect. Then the icon changes constantly from h+ to 3g+ and back. You see its working, but it cant get the data from the net.
What i do then is, i switch off mobile-broadband and switch it on again and then it will work for some time.
But it can be very annoying and i still use my good ol z1c as my main phone, so it would be cool to fix this.
Its not the provider. No problem with that SIM-Card in other phones. Its stock-android 5.1.1
If you have an idea, please help
Some updates on the problem:
If i choose "WCDMA only" as my preferred Network-type the problem is solved. But then i cant get any connection if i'm in an area, where only EDGE network is available.

Back up your data and use Sony PC companion to reflash your firmware , probably you will fix that issue .

Already done my friend.
I once flashed a custom ROM on the phone. The internet was fine, but several other problems forced me back to stock-android. Flashed with the xperia companion.
Sadly this strange problem came back with stock-android.
Thats what is confusing me, too.
