No Service-Hardware or Software ?? - XPERIA X10 Q&A, Help & Troubleshooting

First time asking for help but I can't find the answer to my problem. I have no service on my X10, no calls, text, data. No service at all, just grey bars with a BIG X. I don't know how to tell if it's a hardware or software issue. I don't think software is the problem. I put my phone in airplane mode one night and the next morning turned back to normal mode. I noticed later I had no service. I had been running the Wolf 4.0.0 for about a month when this happened, with no problems at all. I have flashed back to 2.1 and then 2.3, no change. Searched and entered APN's for ATT. I did find some posts about "CRASHING SYSTEM SERVER" but I don't think it applies to this software. Am I missing something? I sure don't want to pay Sony $185.00 just to re-flash my X10 with a quick fix.
Any Ideas???
My setup is:
Wolf_Xperia_4.0.0
2.6.29-00054-g5101537

Try your simcard in a different phone to make sure the sim is working as they can sometimes die I've had a few die on me over the years without even touching the sim since it was put in the phone.

Thanks, but have a new sim fromm ATT, sorry I forgot to mention that.

No Service Issue
I have same xperia x10i with baseband .71
it had same problem few months back and it was working fine
changing sim caused the problem again
now it wont get any signal with any working sim
Is that problem hardware related or software related
FYI i have tried stock 2.3.3 cm7mod and team rom 3.8/3.9 but no service...
Help plz
Regards,

I don't know what the problem was with my phone. It started working one day and has been fine ever since. I do know that I was using the phone in a weak signal area, 1-2 bars max, before it stopped working and when it started working again I was in a full bar area. A software glitch or antenna problem, not sure. I have 2 of these phones and side by side the network radios have completely different signal profiles. The phone I was having trouble with still gets half the signal the other one gets.
Thanks

[Q] X10i phone function abnormal , because of task manager ?

my firware is R26 Root. My friend told me many times my phone signal is not available. but i checked the phone , still with signal strength.
I doubt the main reason is I installed task manager to control memory usage. It might close some important program or service to cause phone function abnormal.
I ever swith to flight mode then back. this still can't solve it , until i power off , then power again. Any one know which service or program must be exist to prevent my phone working perperly ? Thanks.
I also have the same problem, sometimes my friends try to call and it goes straight to the voicemail service, even when my signal is at full strength...

My phone has been doing the same thing recently. By any chance are you both on Orange UK? There have been alot of data and network issues recently. Try phoning tech support and they have an automated message saying that there are problems. It's been going on for nearly two weeks on and off. Its getting really annoying now.
O2 uk here, have had this issue since I got the phone on and off.
Flashing, updating, rooting, nothing has corrected it.
It is also a problem for some of my friends on different networks, and this leads me to believe it is the phone, software or hardware not sure, as opposed to the network.

I find that when i enter my pin code en register my sim. After it went to flightmode. I won't go into flightmode again after that. Unless i use the taskkiller again.
Also not everytime i kill all apps, this happends.
Same with you guys ? Running Rooted R2BA026 here x10i
OrangeUK here... same problem... will phone them tomorrow and post here the results.. I also noticed a strange error when i activate and deactivate plane mode, 3g stop working... and i need to reboot the phone to get it to work again.. same thing happen when I deactivate and activate again MMS&DATA Connection... then i have to reboot the phone to make it work again...
Anyone has the same prob???

Task killer gave a strange fault for me. Make a call, talk as you do, screen goes black, loud click in ear piece, screen comes back on. I had task killer set to work on screen going blank. Removed it, fault gone.
Sent from my X10i using XDA App
Remove the dialer and the android.serviceprovider.apk (something like that) from the task killer auto kill list. Put it on ignore list. It should work fine after that I guess.
Please don't even start about orange uk. I switched from o2 to orange so I could get a white x10. Worst mistake I've ever made. Where I work I get constant signal drop out even though the phone says I have full signal and it 3g signal is always inconsistance, and I work in a major town in essex. Had these problems ever since I've owned the phone and had many an argument with customer services who dont listen to you and just say there are a couple of masts in the area that are broken. Basically orange are full of s**t about there wonderful coverage in the uk!
Sorry you have had to read all that, just my 2 cents.

Signal Loss

I've been having this problem for some time but wasn't entirely sure whether it was my network (O2-UK) or the phone. Basically at random intervals my phone will lose signal, I didn't realise quite how often until I installed No Signal Alert and today for example I've lost signal 5 times, not for any more than 30 seconds each time.
The reason that I think this is a problem with the phone is because I've noticed that if I'm connected to wi-fi that also cuts out at the same time.
Is this something anybody else has come across? It's a non-rooted X10 on R2BA026.
Have been having exactly the same problem for the last few weeks. o2 have had the phone back for repair twice, the 2nd time it was exchanged for a new handset but still seems to be occurring. My brother also has the same phone, network and problem.
Strange that all the problems are occuring on the same network. I originally rooted my phone and upgraded to the newer build, don't know if you're on the normal O2 software?
Would be interesting to know if anybody has had the same problem on a different network.
Same Problem
Hey,
im in Australia, with Optus On SE X10i
and ive had the same issue whether rooted or not, but only since upgrading to 26 software, didnt have this issue on 16, also when i sued to use Advance Task Killer, if i opened the program and killed all apps, then 2of 3 times my signal would go down to NO SERVICE for about 30 seconds and then come back full force.
To me it seems like a potentual software issue that specific to 26 software
I've noticed that when I use a task killer to close the sony ericsson backup app that causes me to lose all signal (network and wi-fi) straight away, but I still lose signal randomly even with that closed. I never noticed it happen before I upgraded to this software either, so you could be onto something there.
How do we go back to previous versions?

Well I've just flashed it using the X10 flash/unbrick tool and went incredibly smoothly, now back running 016 and reinstalling all my apps using trusty astro. I'll make sure I keep the no-signal app running and let you know whether this has fixed the problem.

Low Reception On X10?

has any one else noticed the drop of signal on this phone? it works fine at home but as soon as I enter my college class room, the service can't be found, this is really annoying, I don't receive my texts till I exit the room and even then, every text I send seems to take ages to actually be delivered to the recipients phone. any one know of any fix for this?
running 2.1 official with pitch black theme. Xrecovery installed.
Did it start to happen after you installed the black theme?
Sent from XDA Premium from my X10a rooted running 2.2.1 Pure CM Rom from kxhawkins
no, its always happened. is this a problem all X10's have? as soon as I leave the room/college, it gains its reception again :|
I dont have that issue at all. Have you tried flashtool to try to fix the issue, or seus from sony? It could be a glitch in the phone. Have you used flashtool before? I can help you with that.

I have att x10a with 1.6 and I was constantly dropping calls worse than the iphone.. Called up ATT and they said swap the sim.. Did that and still nothing so they replaced the phone and so far no issues..
I've swapped sims, it didn't help, what would the flash tool do?
It's a hardware issue.
Not much you can do.

Its definitely a hardware issue, at least mine was.. If you’re under warranty get it replaced either via your carrier or SE
if I flash another baseband would that fix it? this phone works perfectly at home and other places, just as soon as I enter college, it loses reception. would another baseband be worth my time trying out?

No.. i have a similar issue.
and there is nothing you can do.
I wrote a petition to my service provider about this.
And the fixed a problem with the tower. "only cuz i know they take budget cuts"
The gsm modem is full of ****.
I don't know if it's a software or hardware issue.
But so far there is no fix for it.
As I posted above I had this very same issue.. ATT says couple of their towers are still down in my area and could be an issue.. It isn't.. The replacement phone I got last Friday has been very good… So clearly it was an equipment problem.. Are you still within the 1 year warranty? If you’re get it replaced ..

Xperia P unable to change Network Mode

Hello everyone, I am having a problem with my new Xperia P. I first got the phone on ICS. 54 FW and for some reason the option to select Network Mode (switch to GSM only, WCDMA only, etc.) was greyed out. I noticed that in an area with conflicting GSM/3G signal my phone lost signal for extended periods. I though by flashing a new ROM (Vision V4) that the issue would be solved. I flashed and am now able to access the Network Mode selection. It was on WCDMA preferred/GSM and I clicked GSM only, the phone immediately rejected this and went t\back to the state that it had been in. This is basically making my phones network features useless and I suspect the battery life is suffering as well. I flashed stock .75 ICS and even back to .54 ICS and the same issue occurs no matter what I flash. I went into the "hidden menu" accessed via button combination in the dialer and tried manually selecting GSM only from the list of preferred networks and the same issues occurs, no matter what option I choose, the phone immediately changes back to WCDMA preferred/GSM. This would not be as big an issue as it is if I lived somewhere else with better signal, but my home and work environment are both like this so it is a major issue.
I urgently need help in this matter, I have read about similar issues but either the thread has no replies or the suggestions do not work. I had read about some Sony forum members asking if I the persons had cut their micro SIM. I have, so I ordered a new micro SIM ready to be activated and it's on its way. These suggestions about the micro SIM were also answered with replies stating that they changed out the SIM and the error still occurs and I suppose it will more that likely persist in my situation.
If anyone could, I really need some help. Thank you for reading.

Hey mate,
Im not sure but I think you have a wrong baseband which might be causing the issue. (not sure cause i remember hearing somewhere that P covers all bandwidth etc )
If that might be the case, you need an FTF for your specific model to flash its baseband
Again, not sure so try this only if you dont get any replies soon

Yeah, I think it may be something with my baseband. Every now and then I get an "R" above the signal display meaning I am technically roaming but this is very random. I don't really see any flashable basebands for the Xperia P though. I will do more research though and thank you for the suggestion. :good:
Well, couldn't find anything so I just sent it back to the seller for a replacement. Mine had a bad pixel on the screen anyway. Here's to getting one that works in about 2 weeks..
I too have the same issue but my problem is that my device freezes the touchscreen on 2g network. On every Rom that I have tried.. I am still waiting for a fix..
Tried to change the SIM and network still the same..

Yes, that is very weird.. Are you still able to switch network modes? I'm on AT&T so the network compatibility should be fine, I'm just guessing we have defective units.. I emailed Sonymobile about the issues and got a response telling me that some carriers have a lock on their networks. This isn't true though because I have plenty of phones (Android and other) that had worked with 2G/3G with the option to select and it worked fine. I do this to all the Android phones I have ever owned. Hoping the JB update addresses the many issues we are all having with the many ICS iterations. I wanted to stop using Japanese smartphones (currently having to use F-10D until I get a good replacement) because of the hassle with use between countries and there being no development existent. I thought I could get a headache free experience from a less strict supplier but it seems I just can't have a good experience.
Like I said, I sent in for a replacement and should be getting one soonish, I don't know what I'll do if the same problem occurs except just wait for JB and see what it holds.
Can anyone with this phone on AT&T confirm that my phone was defective and not just (supposedly) carrier related?
I bought it from Saudi Arabia, only 3g works but freezes in 2g after some usage.. I am from India. I think unlocking SIM LOCK of my phone might fix the issue..

HELP! no signal

Hello
I got my xperia z2 D6503 2 days ago brand new sealed. I inserted my Net10 sim and it worked like 1 day and than I noticed that there was signal issue first I thought it was because of area than I found out it was phones fault since same sim card worked perfectly on my old xperia z and also on xperia z2 Tab and on my brothers galaxy s4. strange thing is it shows low signal only when LTE is on and I can send and receive text messages but I can't make calls. as soon as I turn off LTE it looses signal and no text or call go through.
I tried factory reset, 2 different sim cards, even bought new sim card, numerous restarts and nothing helps. searched web for this issue and nothing at all.
so anyone else had this experienced? any solutions?
thanks

Same issue with my z2... only when I hold it a certain way... I'm on Bell mobility in Canada and got the phone a few days ago.
I've been experiencing the same issue ever and I've had my phone over a month, I'm on EE in the uk running the .55 firmware. My phone is currently in repair to fix this problem so I'll get back to see if it can be fixed
Sony has no solution in USA and can't repair so I returned for exchange to seller. I though it was only me so looks like gonna be big issue

Hey, so did the exchange solve the problem for you? I am using NET10 as well and while I do get signal on all networks (2G. 3G, etc..) I notice that it isn't as good as almost any other phone I've had. I live in an area that has poor signal and places that I get 1-2 bars on other phones I get 0-1 on this phone, though when I'm in upper town where signal is great I get about the same as others do. I'm just not sure if my phone is defective or this is just how it is. I really don't want to wait to exchange plus the seller seems reluctant to do so..
I had to fix my APN (wireless &networks -> mobile data).
I Google the correct settings for my carrier(ATT/USA), and saved the updates and it worked IMMEDIATELY.
it's been solid since ever since. Note there are differences for the 3g VS LTE versions. Make sure you enter the right settings.
Good luck!

I did entered correct APN's as I mentioned it was working great for almost day and Than suddenly stopped working so if I had entered wrong APN's it wouldn't worked first time I powered it on. plus same sim card worked well on other LTE phone while was not working on my new Z2, so it was not APN issue.
Try rebooting 3-4 times and then wait. This should solve the problem.
Check the baseband version online and on your phone.
There is also a firmware update but you have to cable your phone to a computer and let it install the Sony software on the PC/MAC ... Mine updated yesterday...
Worth a shot if you haven't done so already.

Thanks man, it seems that's just how the phone is, maybe I can stop worrying so much about that now, especially since this Z2 I have has no defects that are so plentiful on other user's phones.
And like I said, it's not such a big deal when I'm in places with adequate coverage so it's tolerable. I updated to .402 yesterday and there isn't any change with signal but I'm holding out for more updates that can help out with coverage. I'm thinking once the Z2 is released in some way in the US (carrier or Sony store) that there will be an update then that may help us out.
I'm probably the last person to be offering advice in this forum, however, just a couple days ago I noticed I had no data connectivity at all. Calls and texting still worked, but no cellular data. All my APN setting were correct and even though airplane mode was not selected, turning it off and on again got my data connection back. Just something stumbled upon and I have no idea if it applies to anyone elses issue here. Just thought I'd toss it out there in case it helps just one person.

Solve which problem? The one i posted in very first post or the weak signal on my replacement? I did more than 5 reboots to solve first proble but nope.
Now this very weak signal worries me it loosed signal at places where my old Z was great. Hope this phone doesn't end up super problematic
Sent from my SGP521
Sony Service will service/replace the set, if needed. So please do check in there.
phone is amazing everything works smooth, but weak signal is getting on my nerves! looses signal very often and data gets really slow because of low signal even when LTE is available. I live in brooklyn ny and my xperia Z didn't have this issue at all. hopefully this could be fixed soon by software update.
Drop down quick settings from home and ensure LTE is ticked on.
