So,all was well with my z1 and somehow my subconscious thought that I something should be screwed up.
Well,I was getting really bad signal reception in my area for 3g since i barely got 1 bar(though i got 4 out of 4 bars for 2g)
.
Now,I typed in *#*#4636#*#* in the dialer >> Phone Info >> Menu key thingy>> Select radio band(well obviously,i thought that if i could unlock more bands,then i could connect to one with more...power) >> Only one option was avaliable--> "USA BAND"....So much for unlocking new bands.well i selected the 'usa band' anyway thinking that is was the default option,
BOOM..there goes the signal reception and i couldn't get it back no matter what i tried: I tried factory resetting,I tried manually factory resetting,I wiped Dalvik Cache n Cache. I reflashed the baseband via flashtool.AND STILL NO SIGNAL( I blame sony for including stuff like this in their phones)
I searched a lot for fixing this on the web and i found that many people had the same problem as me but i found no answers as to how to fix this.
SOMEBODY plz help me,ANYBODY plz help me.
UPDATE: ok, after flashing a multitude of different firmwares via flashtool,i somehow finally got my signal back...yah. So if this happens to anyone in the future,...then go crazy with flashtool
A full reflash is the only way I have come across. You can hardly blame Sony, they didn't give you the code (which works on pretty much any phone).
i fixed this problem, reflashing only kernel (stripped file for LB)

Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?
I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.
Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.
I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help
Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?
Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!
So I had some escapades today, I had my SGS running jellybean, then I tried to change the screen density and bang, bootloop. I panicked and after some odin fiddling managed to get it booting Darky using odin. I was in a room with no signal at the time so I thought nothing of not having any signal, even so I then went ahead and used recovery to reinstall my Jellybean rom since that's a bit nicer than the 2.3 Darky.
Long and the short of it is, I can search for networks in my options and it will find them, but when I tell it to connect to one it says "Can't connect to this network right now. Try again later"
I have tried later and surprise surprise it didn't work. I have tried installing a different radio, clearing the dvalik cache and fixing permissions as well as a few other things. Please can anyone suggest something, this seems to be a very uncommon scenario and it's stressing me out that I can't find any solutions.

Yeah I've checked them and unfortunately they all seem to be in order still, though there are a lot more settings than any website offers things to put in them
same problem
i am having this same problem on all cyanogenmod 7,9,10. i have tried many radio and modem flashes. i can scan and see networks, but i can never connect to them.
have you made any progress?
Problem is EFS folder which tends to do with IMEI.
To fix it you need to copy the backup EFS folder from your SDCARD to the root of your device. (/)
If you don't have a backup you'll have to ODIN back to stock and re-root....etcetera

thx
thank you for the response. I put it back to stock lastnight before bed so i will give this a try.
i have the gti9000m from bell in canada. I updated it through kies to 2.3.3 gingerbread and it all went badly. It would boot up and load to the os be on for a bit then reset. It turned out to be wifi problem, running it on airplane mode stopped it from rebooting. Then if i tried to turn on wifi it would quickly reboot.
So then i tired all the cyanogenmods, which worked it stopped rebooting all the time. however the wifi would connect and work for about a minute then it would drop. doing the
1.turnOn gps
2.turnOn wifi
3. turnOff gps
this would let the wifi work again for about a minute. I tried all the wifi fixer apk, and a bunch of wifi.zip mods, and then ping the router gateway constantly, none solved this problem. Very annoying because i need the wifi working for develpoment of apps. I have spent a great many hours on this problem. lots of people seam to have this problem but no solutions have wokred for me.
So, my questions are....
1. does your wifi work?
2. how the heck do i get mine to work?
back to stock
After going back to stock then upgrading connecting to network operators is fine.
wifi is still broken though
Hello everyone,
As the title says I have a problem on my S3 (i9305).
First of all I want to know that it has been dropped or anything,
I put the official version 4.1.2 (the DBT for Germany was the latest then) instead of 4.0.4, rooted + busybox + modem network Vodafone Romania (XXBLL5) and it worked just fine until yesterday.
I arrived at work I checked my mail via wifi network, I disconnected I put on charger and after an hour I removed to make some mail and then give it to initialize wifi stupor show he wants to start and stop and did not want in any way to start a (looks like starts and stops).
Good now seeing that I got it and I somewhat empirically and did the following things:
-clear cache, wipe Dalvik, reset permisions - still did not work
-restore the Nandroid for wifi - did not work
I managed to got mad and threw factory reset - still not working height
-continuing with nervousness I flashed phone about 4 times with different versions 4.1.2 and version 4.3 but bootloader of 4.1.2-
Normally he did not want none and some gave the "camera failed" error.
All versions have been flashed after wipe cache, dalvik and factory reset so I say something to remain excluded from one another.
Now I'm on a Vodafone version 4.1.2 on sammobile after I haunted a bit on the internet I saw that its more people with this problem and someone had an alternative after you rename the file "wpa_suplicant.conf" in root / data / misc / wifi.
I did this and go but it is something temporary peak for once stop or restart your wifi is not working and another thing
mobile internet does not work without you come in APN and reset its there.
Sorry I did read both but I do not understand the phenomenon and to solve it because there can not be a hardware problem but rather a problem or write permission on the root folder.
And now comes the question: is there a solution to my problem or a way to see if some parts are protected to rewrite or corrupt?
Sorry for my english i use google translate.
Hello, ive got a Xperia Z1 C6903. After install and almost immidiate delete of this app "4g LTE Switcher" phone cant get any signal whatever i tried to do, ive found there maybe some issue with radio rom, can someone pls provide some guide? By the way, the phone is at defaults - not rooted. Thx.

Hi everybody (and sorry in advance for my poor english) !
I am having exactly the same problem as the OP. To explain the situation in a nutshell:
I have the SM-G800F, for about a month. It worked fine, until I moved to the other end of France (it probably has nothing to do, though). Passing on the highway, "Emergency calls only" showed up while I was looking at my emails. The problem is that things never got back to normal.
The situation :
As I said, the same as the OP. When I turn on my phone or I go out of airplane mode, my phone tries to connect to 2G, then 4G / H+. The process takes a few seconds, then any indicator (left of network "bars") disappears, and I can't issue or receive calls, nor use data.
But if I force "2G only", everything works just fine.
I was using a rooted 5.1.1.. In the meantime, I tried several suggestions found here or elsewhere:
-Turn off the phone and on again : Nothing
-Enable / Disable flight mode: Nothing
-Remove / Replace the SIM card: Nothing
-Putting the sim in another phone: everything works just fine, so the problem may not be a faulty sim card
-Wipe Data / Cache Data then use Odin to reinstall a stock 5.1.1 rom (I'm really a noob to find the right words, sorry in advance, but my phone says, under the "version number" field , LMY47X .G800FXXU1BPC4 and the ROM I used is named : -G800FXXU1AOG2_G800FOXX1AOG1_G800FXXU1AOG2_HOME.tar.md5 filename
Manual carrier selection : Nothing
-Turn on Data Roaming : Nothing
-Checker my APN : Everything seems just fine
I can't tell for sure but I do not think it is related to my home. My problem began on the road and took the rest of the trip (2h/3h), and even around in the city, it remains. Moreover, my backup phone and the other people on the same network as me (Orange) don't encounter this problem.
So, I'm a little bit confused and a bit worried because of Knox (0x1: /). If you have opinions, advice, guidance, thank you very much in advance!

No, I really don't know what the problem is I think it's something in the phone itself
I've got the same problem too
Did you find the cause of this issue in the end?

Hi !
Not yet ... I have another phone now but i still try now and then to fix my S5 mini.
So far, nothing worked. Some tech guy told me it was a common issue with that phone's antenna. Also read that from several forums.
Still, i read that some users were able to fix similar looking issues by flashing the modem file with Odin. I'm a bit n00b but i guess i'll give it a try.
Any success on your side ?
You can try searching for your carrier manually and choosing it.

Thanks, but i already tried that many many times. My S5 Mini just displays "Network XXX unavailable" (or its nearest equivalent in French)
Did any of you manage to fix that by flashing your modem file with Odin ?
I've tried additional stuff but nothing seems to work. Back to stock Marshmallow. Still loosing radio signal whenever I enable 3/4G.
Maybe the bottomline is "hardware failure" but who knows...
Thx everyone!

Have you tried a deep reset? If it does not works, try a custom ROM...
Hi !
Thanks for your reply,
I did try "Factory Reset" and "Wipe Cache" while in the Recovery Menu (Home+Power+Vol Up if I remember well). Is that what you were refering to ?
But I think I didn't try flashing a custom rom. Could you recommend one ?

Yes I was meaning this. For a custom ROM i can recommend One of the latest with NOUGAT like Lineage OS 14.1

Hi,
I installed Lineage OS 14.1, it's great but the same problem keeps happening. Everything works just fine in 2G, but whenever I enable 3G or 4G, my phone looses radio siglal and switches to "Emergency calls only" after a few seconds.
Any other thoughts ?
Thx !
As a side question, would you think of any way to rule out/confirm the possibility of HW failure ?
Thanks again !
Did anyone found solution for this?
Hi,
I've got the same problem. Tried to flash with Lineage 13.0, then 14.1 and still the same problem.
Anyone help?
Flash the last modem/baseband, did yoy try *#*#4636#*#* ? You can manually select wcdma only(3g) or lte only(4g) (sorry for my bad english)
still not working
When I choose 3G/2G auto connect from 1 line ti go to 4 signal.. so no LTE /4G for now..
