No signal and can not find network manually - Xperia Z3 Compact Q&A, Help & Troubleshooting

I have replaced the screen for my Sony Z3. After I did that it shows no signal and I am not able to search for network manually either. It is just searching.... When I try to call it says "no radio". Any suggestions?

Missing antenna connection

Two suggestions before panic mode:
1. Remove and reseat your SIM Card. During the repair you may have dislodged it.
2. If you did the installation yourself, go back and check to see if you dislodged or broke the antenna connection during your repair. Schematic available online. If someone else performed the screen replacement, have them give it a check.
There is a YouTube video on dis-assembly (I can't post links yet)
Know that if you go to Sony Support they will instruct you to do a repair via PC Companion -- be prepared and back up anything you don't want to lose.
Good luck

XDA IIi No service.Hardware of software problem???

I recently bought an XDAIIi from ebay knowing that it was defective. The only defect is that there is no service. Apart from that it is working as a PDA perfectly doing the job that i got it for (SAT NAV). Now i starting thinking of the possible reasons that my phone has no service. So in order to check if the hardware of the phone is ok i tried to do a manual network search. When i clicked on the manual search i got an error message saying " Unable to read setting from the network. Try viewing settings later, or disconnect data connection and try again". Are there any ideas of what this message means and is there any way to actually fix it?
Note: I am running pug rom with the 02 stuff stipped.
Your Radio hardware is busted to the best of my knowledge ...
you should hard reset.
I managed to kill the service on my 2i once, I cocked up the registry somehow and as soon as I put my pin in it pretty much straight away showed the no service icon (the one with the exclamation mark) regardless of whether I then tapped on it and tried to get service.
Had to hard reset in the end and bingo the problem disappeared (as I suspected it would), but your problem sounds terminal.
are you sure it has not been blocked / black listed with uk networks.
typical reason for no service would be if it had been blocked?
Didn't think of that...
My alpine crashed while driving with tomtom today and I have exactly the same problem.
Looks like it hard reset time.

[Q] mobile network not available

Hello I'm having difficulties with my i9000.
The problem first started when I smashed my screen. Bought a replacement screen and middle plate frame bezel, including the home button flex cable. I also unfortunately damaged the loud speaker and thus replaced that also. Now everything is installed and the phone works great except for connecting to a network and making calls.
When I dial a number I get "Mobile network not found". When I check available network it finds my network and attempts to connect. Then I get a message this network is not available for this sim card, or something along those lines.
The sim card works in another android phone and other sim cards gives the same message.
The IMEI is intact and correct.
The phone is unlocked
I started on 2.2 and have flashed the firmware with many different types and still with the same message.
Now my question is this, how would changing the screen, middle plate & loud speak have this effect on the phone? Bear in mind that the phone still functioning with the cracked screen and making calls.
If anyone could help put me out of my misery it would be most appreciated.
Try flashing different modems now !
I'd say you might have disconnected a cable or forgot to reattach it. However, that might not explain that you do see the network sometimes. So yes, modem's probably a safe bet.

Ok I'll try this, not quite sure how the changes I made would effect the modem.

All cables have been checked and triple checked, and the network is always visible to connect to. Thanks for the advice I'll try the modem, is there a particular one I should try? I'm in the UK and my phone provider is 3.
Tried various different modems, giving sometimes better signal quality and sometimes worse. None of them have any effect. The message i get when connecting to the network is "your sim card does not allow connection to this network". Which to me sound like it may be locked again. So I'm going to try and dig out the original sim card and try that.
Try some other network and check !
Tried other networks and still no joy. I've flashed it many times now, gone back to stock firmwares and nothing will work. Spoke to Samsung and they just tell me to plug it in to Kies, which does nothing. I'll take it to my nearest Samsung service centre and see if they can fix it.
1. In security remove SIM pin request at restart.
2. Reflash MODEM with odin
3. At searching network check (automaticly)

[SOLVED][Q] One has lost signal and settings

Hey all I have rooted and S-off with moonshine and flashed This Rom to my Sprint Htc One. I then programmed it to work with page plus cellular, in which it was working great for about 3 days. I had gotten a text around 3:30AM & when I woke up the phone had NO signal, service, or data! Upon further examinations, I found that my settings to adjust the roaming features was GONE! The ESN checked out clear thru Sprint so I'm not worried about the phone being shut off or anything. Could this be an H-boot issue or what? I have since reinstalled the mentioned rom above but my settings are still gone. The pull down menu shows the Airplane mode to be on but it is NOT on anywhere else and I can't turn it off in the pull down menu. I hope this is my problem but I really need to know how to resolve it. I've tried to do a screenshot of the pull down menu but it grabs the home screen.
EDIT: I have resolved my issue. When I originally programmed my phone, I left the sim card from sprint in the phone and went with page plus. Evidently, with the sim in place, sprint was able to change some settings to shut off my radio. I found out thru sprint that the phone was activated on july 21st & deactivated on july 22nd. This gave them about 12 days to shut off my radio after deactivation. I went into cdmaws and found what they had changed, switched it back for a working radio again.

I will give this a try and here is a screenshot.. As you see the wifi still works but the radio has been disabled.
Edit: I completed the RUU and still have NO cell radio, wifi works fine. I've only had this phone 3 days before it stopped working and NEVER dropped it or abused it. I have read posts where some folks had the antenna wire come off but I'm thinking this is just what sprint is telling people. I don't see where there would be enough room inside the ONE for the wire to just "Fall Off"!
Sent from my HTCONE using xda app-developers app
Well I still have an Ipod like Htc One! No luck yet on restoring the cell radio and I'm kind of lost where to go from here. I'm guessing if the antenna wire came off, there would be no settings for roaming so I'll take it apart to see if that's the problem.
Help with NV items
I have tried every ruu and even went back to the 1.44 hboot to let my phone update itself to android 4.3. When I do the factory reset, my nv settings stay just as I programmed it to page plus. What I need is for someone to send me a copy of their NV items read thru cdmaws paid version or qpst, any means you have to read Please? I don't need or want any imsi or meid or personal info, just the nv items from a working phone. I'm really beginning to think that my phone needs to be replaced but I bought it from ebay and am not a sprint customer. If anyone knows how I could go about getting this replaced thru htc Please let me know but I would like to try the nv items first. If I messed up the phone then I'll fix it but I really think I have a hardware issue, otherwise I'd never think about a warranty.
Just out of curiosity, when you flashed the software to your phone and you lost your signal and settings, did the baseband on the phone show as "Unknown"? I get that from time to time, either due to incompatible software or a bad flash.
The phone actually worked great for about 3 dats and the baseband was and still is showing. I feel that I may need to send it in for warranty but I'd like to have the original nv items to flash first to see if my cell radio will work. The wifi works fine and I can change the radio in *#*#4636#*#* to anything I wish but that still doesn't give me reception. I've been flashing phones for 3 or 4 years & have seen the baseband show up as unknown but I've never lost cell radio until now. :crying:
" I don't see where there would be enough room inside the ONE for the wire to just "Fall Off"! "
Well it actually can. Not fall off literally but rather disconnect from its socket. This has actually been an issue with the HTC OneX's wifi antenna also.. If u check out this guide: http://www.slashgear.com/htc-one-teardown-proves-durability-a-top-priority-28275687/ you will see the black cable that goes from top to bottom and connects two pcbs. That's your culprit if indeed you have a hardware issue. What i would do if i were you is first find one of my carrier's antennae and go as close to it as possible and see if you get any reception at all (best chance i guess is in a subway station). I guess that once you're that close to a transmitter your circuitboard is sufficient antenna though i might be wrong. If i am right and you get reception than its hardware. If you dont get reception than the cause is uncertain..can be hardware, can be software.. Anyway, i wish you best of luck with fixing your problem!
Cheers!
Wish me luck, today I'm headed to the sprint store to see if the tech can find anything out for me.
Edit: No such luck! The guy told me that when the phone was deactivated thru sprint that the radio was shut down and if I got a contract to activate the phone, then it would work! Hmm I didn't buy that so I told him I programmed it to page plus which worked for a while & bla bla bla... No go. Does anyone know how or if I could send it back to HTC for repair?

[Q][SOLVED] Wifi not working on Z1s?

I've tried contacting sony and someone that I could hardly understand said he couldn't help. I then said I would just like to return the phone and thanks for your help. His response : "Well that's your problem. Goodbye"
After that nice experience, I thought I would ask here.
I can connect to a wifi network, but I can't actually access the internet. This happens on every wifi network I've tried. Data works fine, and wifi will connect to any network, but I can't go anywhere.
Any ideas?
EDIT: Solved. It was a hardware problem according to tmobile.

have u tried repair ur phone by PCC?
or simply restart it.
or check proxy setting if something set wrongly.
when u connect to wifi it means hardware is OK then while u cannot send / receive data it should be software problem.

Thanks for responding. I forgot to mark this question as solved. I just got it replaced at the store...they thought it was a hardware problem and I didn't want to deal with all that.

[Q] Xperia Z GSM problem

Hello!
So I got a Sony Xperia Z in pieces, and after assmebling it the phone turns on, everything is working except for GSM module. The phone sees the SIM card, but it can't see any network. I can't even make emergency calls, and if I try to search mobile operators manually, it just blinks a popup, and says it found nothing.
Here's a screenshot from phone status screen: http://kazshu.dyndns.org/Screenshot_2014-11-24-22-04-37.png
I tried to find a solution on google, but I haven't found anything. :/ I have replaced the micro usb port since it was broken, but I didn't change anything else. Could be the GSM chip broken too?
Thanks for any help, and sorry for my english.

You probably didn't connect antenna cable on the right way. Check the cable.
