No 3G signal at all, but not quite the same - Galaxy S 4 Q&A, Help & Troubleshooting

Hello, first to say, im not a newb, noob, newly registered, or a guy who dont understand anything from android.
Im not posting stupid topics, or topics which answers can be found easily on internet/google/xda/forums and such.
I am running stock rom, only rooted (i used to root it only to apply some xposed settings and clear some unnessesary apps, nothing more, nothing less).
Here is the description:
My phone has no warranty, i bought it online, brand new from UK, simfree. At that point, i had no problems with the connection. i received OTA Update - about 50-60 mb, but the phone remain 4.2.2 as it was. I still had no problems with the connection. After some time, the phone was left alone inhome for a few days, may be a week, it was turned off and it was not used at all. When i got back, i inserted my sim card, and i saw it is showing only G icon, and no 3g/h/h+, nor even 2g. I live in big city with very good network coverage, so its not network problem. I dialed up the customer service (Globul Telenor Bulgaria) , explained them my problem and asked them to check if its operator's problem or sim card problem, but it is not. The sim is fine, so is the network coverage. I dont have other operator's sim card to check the phone. I tryed several possible solutions found in google/xda - turned off the phone, removed sim and battery and left that way for few hours, still have the problem, tryed to switch operators manually and register sim card to other operator then back to mine, not working. Several times reseting/ deleting APNs, switching airplane mode, data off/on, adding apns/searching for networks and all available combos, not working asked Globul Customer support to send me new settings- not working. The only obvious thing i havent tryed is the factory reset (I still need to do a backup first and dont have time to do it right now.)
In Settings- More networks - Mobile networks- Network mode i have 2 options - 2g/3g auto connect and 3g Only. When I choose only 3g - i lose any signal, like there is no sim card. Reverting back to auto 2g/3g is registering my sim back to Globul network.
Then i decided to root my phone if i can find a fix for the connection. Rooted with CF-Auto-Root thru Odin. (The 30sec Root)
Looked for some tweaks in xposed modules and settings, i couldnt find anything related to 3g. Still looking for a solution...
I repeat - my phone was completely stock and non-rooted when the problem occurs! Now is rooted with stock rom. (this is the diffirent from every topic i searched.)
Im attaching some screenshots, if someone can help me. 2g is really annoying and slow as hell.

Well the first thing I would do is update your phone. You are running 4.2.2 which is old. Update to the latest version, that could either be a stock rom or a custom rom.
After that do a factory reset. Make sure you backup your internal storage etc, because it will wipe it clean.

Factory reset, updated to 4,3, after that 4.4.2 problem still persists.
No 3g at all. Its not the sim. Any way to fix it ?

Soo no way to fix it? Should i give it for repair?

[URGENT] X1 can't find T-mobile signal

I have used my x1 for four months in America with T-mobile. The phone had no problem until yesterday. However, yesterday, the phone began to lose signal and automatically rebooted several times. Then, finally, from the afternoon, the phone totally lost the signal, and kept looking the signal.
I took out my sim card and plugged into another cell phone and it worked. So, I thought it was the problem of the rom. (I was using Touch-IT 4.5) I downloaded the new version of the rom, Touch-IT 5.6, then flashed it. However, it did not solve the problem. So, I flashed with the original SE rom. However, the phone didn't work either.
I contacted T-mobile, and there was not problem on the signal on my region. I thought it might the problem of data plan since I do not use data plan. So I used Advanced config and killed every option for data plan. However, it still does not work. I tried to do settings manually. changing band, carrier, and every possible options, but it does not work.
Interestingly, the phone worked two times today for a short amount of the time. However, after the reset, it is gone. Other than phone function, I do not see any problem.
Even now the phone keeps searching the signal. What can I do? I read another article that is similar to my case, and they say even after changing the sim card, it does not work.
Anyone has the same issue? What can I do? My phone is dead for two days, and it messes up so many things. Please somebody help me.
Have you tried redoing the connection setup?
try clicking on signal antenna then enter settings click on network and manual select your network, will take a few mins to find networks if it connects manualy just select auto again and hopefully it will fix it., worked with mine.
Thank you guys
Thank you guys. Yes, I have tried both of them, but it still does not work.
In Connection setup, I chose United States and T-mobile, and the screen to choose between T-mobile and At&t. I select T-mobile, and click Register. Then, it goes to the searching mode again, and nothing happens.
I assume that somehow, the phone finds networks, since it does show the options to choose (T-mobile, At&t). But something is not right, and it messes the set up. I do not know why.

Nexus One network issue

Hi, i was using CM7 for a week, then suddenly, the mobile network begin to be freaky, cant stay on a network, cant make call and anything, I already cheked the apn settings and everything..
also switched to wcdma prefferred, to gsm only, or to wcdma sometime got signal, but after 1 or 2 minutes, cant connect to a network...
anyone can help please..
I'm having this as well ever since the update.
Gingerbread is half-baked if you ask me.
it seems to make and receive calls only in EDGE (in GSM ONLY mode), but when i change it to preferred wcdma or to wcdma only to get 3G, sometime get full signal but cant make any calls and also cant use data and sometimes got no service.. only in EDGE mode..
all this happen after using CM7 for a week... anyone please help..
baseband and radio are 32.50.0032U_5.12.00.08...
I also restore it to stock to FROYO FRF33 and the same issue, dont know what cause it..
I'm not sure it is fully related to gingerbread. I'm still using CM6 and had this issue on and off for about 3 days. It seems to have cleared up for me (knock on wood)
Sent from my Nexus One using XDA App
yess im having the same problem, i also noticed it after flashing to either honeycomb alpha or the new gingerbread update [i did both within an hour] but i cant fix this problem...:/
still cant connect to 3G, only in EDGE mode...
cant connect to a 3G network, already changed the radio to 5.08, 5.12 and downgrade it to 4.06 and nothing...
anyone know this issue??
if I cant solve it, I might gonna sell my Nexus One..,
Network issues have nothing to do with the phone, if they're constant with different ROMs. Check with your service provider.

is not the service provider, I change the sim card to another phone, and the 3G works flawless.
Also, put another sim of other carries with the same band, changed the APN settings, and it's the same problem with 3G, only work on 2G...
In that case, 2 options:
1) Wipe and check again.
If still doesn't work -
2) Hardware failure. Use the warranty.
I've been recently (1-2 months) battling with Data problems also and I don't know what the issue is. I know it isn't my Carrier because I just spent the whole month on the phone with them and they actually sent a Guy TO MY HOUSE to test the connection. I've never had problems before until around CM7 and me switching plans (which is what I thought it was).
My problem is that it works, but data just stops and doesn't want to reconnect. I have to toggle Airplane mode or reset to jump start it. I think changing towers while driving might do this too.
I've done the same tests. Changed Sim, Swapped Sims, etc. EDGE seems to be stable for me but 3G is wonky. I've flashed a PASSIMG and started from scratch that way back to root and CM7. I've downgraded my HBoot and reupgraded it. I've wiped and changed radio versions.
Right now I plan to swap to a few other Gingerbread roms and see if that fixes it. My N1 being my only internet connection it is hard to download other custom roms but I grabbed a few from work and put on my SD card.
I'm not blaming CM7 but at this point I'm really thinking about changing phones.
Ive read that there are issues with the Nexus One gps. Is this true and if so, what issues have you experienced?
PS. GPS doesnt have anything to do with the carrier does it?
well... my nexus already have 1 year, I'll sell it in a very cheap price, and buy the INSPIRE 4G and root it...
thx for your help guys..

HELP! Unable to connect to any mobile network - DHD

Hi Guys,
Wondering if anyone could help? I think I may have turned my DHD into an expensive mp3 player! I don’t seem able to connect to any mobile network Apart from that the DHD functions perfectly (working wifi/gps) - it has been working fine in the past
I can’t make/receive any calls / text message. When I try to connect to a mobile network I receive the following error:
- If I choose the network manually myself (o2 for me) I get "Your sim card does not allow a connection to this network"
- If I try going for the automatic option I get "Unable to connect to this network at this time. Please try again later."
- I'm also getting the notification every 10 minutes to "Set current time" - I don't know if this is related but I assume so since both issues started at the same time!
The problem occurred when I decide to give RCMix a go through ROM Manager. It appeared to flash fine and was running smooth and quick until I noticed a few hours later I had no mobile connection I'd done this a few times before with RC 7 and CoreDroid and hadn’t experienced an issue before.
First thing I tried was to recover to my previous setup before the flash (using ROM Manager) - the phone restored however the mobile network still remained unresponsive! ...this was the same for all my previous backups. I tried clearing cache and dalvik-cache. I even tried reformatting the phone at one point.
I know it's a fault with the phone and not the sim, I'm just not sure what. I've tried my sim card in another DHD and it worked fine. I have also tried different o2 sim, an orange, vodaphone and T-mobile sim card in my phone – all of which give the same problem.
I’ve tried resorting the phone with a few different RUU’s, and even a German one just because it was o2 branded and I’m on contract with them:
- RUU_Ace_HTC_WWE_1.32.405.6_Radio_12.28b.60.140e_26.03.02.26_M_release_155891_signed
- RUU_Ace_HTC_WWE_1.72.405.3_R_Radio_12.28e.60.140f_26.04.02.17_M2_release_161342_signed

- RUU_Ace_O2_DE_1.32.207.1_Radio_12.28a.60.140e_26.03.02.08_M_release_153755_signed
I then re-rooted the phone with the use of Visionary+.
I’ve tried turning the radio off then back on, both by switching airplane mode and by using the hidden option *#*#4636#*#* and I’ve also tried re-flashing the radio and even a different more up-to-date radio:
- Radio_12.28b.60.140e_26.03.02.26_M (original)
- Radio_12.39.60.19_26.06.04.06_M
I’ve checked out the APN and it appears to be correct for o2.
I’ve done simpler things like restarting / powering off, removing the battery, re-seating the sim, re-seating the sdcard and booting without the sdcard!
All in all I’m running low on idea’s Could anyone please help or throw some idea’s at me, it would be very much appreciated!
Thank you.

Double check your SIM card slot to see if its clear of any debris. Other than that, there is a definite fault. Was your handset originally branded?

HTC HD2 with error connecting to the network problem
I have the same problem! I bought a phone from ebay "new" and I have not been able to connect to my network AT&T. The phone has android gingerbread 2.3.2 Nand, and I have tried everything in the book to see if I can connect to the network but to no avail. I have been going on forums for the last three days, and if anything, I just want to know what is wrong with the phone. My sim works on other phones fine. There is enough signal in the area (ive always had signal where I live), and tried resetting, taking the battery off, flashing different roms, even went back to Winmo and nothing has worked yet. My IMEI on the phone was different from the one the box, but was the same on the phone as on the inside IMEI.
WHat the heck is going on? Please ideas or help!
Hi Guys,
Thanks for the quick replies...

Tried clearing the slot, there is no visible signs of blockage... also I bought the handset second hand - I've never seen any branding however when I bought it the previous owner did tell me it was previously locked to vodaphone and he had rooted it so that he could use other sims cards. Which is why I orginally tried a vodaphone sim card too.
Thanks for your suggestions so far guys
Just a quick update, I've been grasping at straws and I've also tried a few more bits below, none of which have worked... I think I may have to leave this one to rest. Just wanted to let others know who may be experiencing the same issues

Replacing the mtd0.img as mentioned here: http://forum.xda-developers.com/showthread.php?t=691639
It sounds like a fault. If it was network barred you would still receive a signal, for emergency calls. Can you return the handset to HTC for a warranty repair?

I still get a message on the lock screen saying Emergency Calls only - although admittedly I haven't tried calling the emergency services to check if it gets through.
Not being the original in-store purchaser I don't even know the age of the phone but I'm guessing probably over the 12 month warranty period, sod's law - I'll give them a ring and see what they say

My DHD was from the first batch and is still covered by warranty. How did you check to see if the IMEI was blocked?
I had a similar problem to this one. My mobile data connection gave out after my DHD's temp reached about 38 degrees while playing with it in the sun. A little while later I lost coverage completely, same as you. I tried everything, flashing ruus and re-rooting, re-s-offing, everything. Ten different ROMs, radios, kernels etc.
Eventually I gave up, figuring I had confirmed it was a hardware issue, and popped my sim in my old nokia so I had a usable phone and to get on with my life after wasting so many hours. I left the DHD with the battery removed, and ended up not coming home for a couple of days.
When I got home and decided to start playing around with the DHD again to see if I could get it working properly, I noticed the issues were gone.. I've tried to reproduce this problem out of curiosity, leaving the led light on high for a while, making the phone hot. Nothing. Since then I've flashed everything imaginable, and I've switched back and forth between two radios all week. No problems.
Strange, I'm guessing I have some form of hardware damage, but everything is running smoothly now at 1,5 GHz - no unstability of any kind.
I have done that actually! I took the battery off, and put the phone back in the box just to get on with my life. I left it sitting for a day and a half I guess, and I came back BUT unfortunately, unlike you, the problem is still there. The phone tries to look for signal, but it can't connect to the network. It does find the network and identifies it by name, but does NOT connect to it.
Sounds like a hardware fault Bob - Give it back to Rob!
or try and get HTC to fix if still in warranty?
Thanks! I thought so, too!
Hey did you solve problem?
I have had that emergency calls for 2 day,s i am waiting only. Please help.
If you find that your GPRS data connection connects but you have no GSM signal do the following
*#*#4636#*#* choose radio off and then radio on, be sure to be in a location with a STRONG GSM Signal and your phone should connect. I have had the same issue with my Desire HD and have been surviving with this workaround as nobody else seemed to know
Stiill same :S Selected networkd unavailable error
Try changing sim, or it sounds like blacklisted IMEI.
But my sim works on other phones and other sim cards work on my Huawei?
I was reading through this hoping desperately that somebody had found a solution. I had switched to Cyanogenmod recently but had GPS issues, so I tried flashing a new radio and RIL. Now I can't make any calls/texts, etc. as described here.
Tried several other radios/RILs, tried nandroid restore, tried flashing whole new ROM (LeeDroid). Still the same issue. Tried the *# codes listed here, no luck.
Please let me know if anybody has solved this one. I really don't need a paperweight right now...

[Q] Unlocked G2 on emergency calls mode only.

Hi all,
This is my case with the hope of getting any help or lead in order to solve my problem:
After a long research I bought an brand new LG D800 already sim unlocked in the US and brought it to my country (Costa Rica). I made sure the frequencies supported by the D800 are the ones used in my country. In fact 2 years ago I bought another phone that uses same frequencies and had had no problems ever.
As soon as getting in my country I placed the SIM card I'm using in my current phone into the G2 and it recognized the signal and connected to the operators network. I started to make and receive calls almost immediately, and also SMS' without issues. So I started to migrate all my data from the current phone into the G2. I used Titanium Backup for this, so I rooted first the phone using the guide I found here, and basically what I did is installed the apps from Google Play and then restored data using Titanium.
After the second day of use suddenly I found out that I wasn't able to make or receive calls since the phone lost connection to the operators network only allowing emergency calls but the signal bars were full (see scren capture). Sometimes when restarting the phone I get "Phone not allowed MM6" message just after the phone tries to connect to the operators network.
Went to the phone company offices and they tried to help me and made some simple tests, without changing anything inside, such as checking Android's network configurations, checking in their system to verify the IMEI wasn't blocked or reported (the IMEI is clean), also checked the sim configuration and after more than 45 minutes they were not able to find anything wrong in their system or with the phone itself. They also made a final test taking a working sim and put it into the G2 and gatting same emergency calls mode, and took my sim from the G2 and put it in another phone and that phone was able to make and receive calls. So they concluded that the phone has a "built-in" configuration or damage that impedes the phone to connect to the network. They finally suggested to ask the seller to apply the waranty, which is not a viable option since I'm not in the US anymore. This G2 is using the stock ROM (see screen captured).
I've been in close contact with the seller, and he had shown interest in this case but unfortunately hasn't been able to provide much support or help to solve the issue. He reports that he has contacted other buyers of this same phone, also sim unlocked by him, and they all are using their G2s normally. Didn't provide where their locations are tough.
My own conclusions here are that the G2 IMEI is not blocked by the phone company, that there is some kind of fault in the phone that when trying to connect to the network, the network doesn't "like" and rejects connection, althought it worked at the begining, and I'm not able to determine if the fault is software or it's in the hardware of the phone.
So I'm trying to understand what my options are at this moment:
Try to return the phone to the seller, or ask an LG representative in my country to change the unit. Which seems to be very difficult.
Reflash the unit with a stock ROM and reestablish the warranty. But being unsure if this will solve the issue.
Reflash the unit with a new ROM and loose the warranty, and again, being unsure the issue will be solved.
I'm really frustrated and at this moment and have no idea on what to do.
Any ideas or insight will be appreciated.
Thanks.
NOTE: I reinitialized the unit and lost any signal (see screenshots) but received update notifications from Google Play and was able to upload the screenshots into my Dropbox although no signal is shown in the status bar and no WiFi connection is established, only data connection thru APN (I Assume).
Go into status, what's IMEI say?
Sounds like EFS issues. I take it you didn't back it up after setting up on carrier and flashing?
Of so, you have some manual work to do with diag mode and a couple apps via pc.
Hi Steamer;
Under status I see 3 items:
1) Phone Number: shows"Unknown".
2) IMEI: shows the number printed on the box, on a sticker on phone's back.
3) IMEI SV: shows"03".
Where can I learn more about EFS issues? Are there tutorials?
As you say I haven't done any backup thing.

Hi again Steamer:
After reading quite a bit about EFS issues now I understand much better what you meant with your post.
And as you said I didn't back up efs folder, I even didn't flash any ROM yet in the unit. The only thing I did was a 'hard reset' to the unit using the Power + Vol. Down method, after having several 'com.android.phone' errors due to backing up data from Titanium.
The phone went to factory state, I put the sim card and everything went back to normal again, meaning that I was able to make and receive calls. Like 4 hours later the phone went to emergency calls only mode, and from then on I'm not able to take it out of that mode.
So I wonder if the efs folder could corrupt after that factory reset. Is it possible?
Thanks again and any light is greatly appreciated.
It is not in its own partition on this device, but in system. A hard reset shouldn't have caused corruption, but it is not impossible. Your IMEI is intact then, that is good. From what you said about it working partially, your EFS is most likely fine as well. There is a thread here to get files with custom recovery zip file, or you can use adb commands to do it yourself. I don't have guides off hand, but Google is your friend, just specified this phone in searches. Try a new SIM. Sounds more like SIM /carrier issue now as you are out of "activation". That is why emergency is popped and unknown number. The SIM itself may and most likely is bad(or carrier has an issue with your account), in turn it can't communicate with the server causing non activation on network search. Priority to SIM.

Hi i have similar issue with my LG G4 H818P dual sim... after factory reset i often face emergency calls only issue despite full signals... sometimes i able to make and receive calls but most of the time despite my sim registered on network and i get full signals when someone tries to call me he get message as my cell is off.... really annoyed and i flashed latest rom v10e but same issue. Same sim when i use in note 3 then no issue what so ever

I had the same issues. Bought in Us using now in India. Go to settings..tethering&networks.. mobile networks... international data roaming and select standard data. Switch off and switch on your phone .
This will happen when you use, internet over gsm. If you disable internet or if your phone loses signal while switching between edge and 3g/4g data, this is tend to happen.
Similar Problem
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/show....php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

[Q] Need help - Unlocked Japanese Note 3 no longer works!

Hi All,
Please help. I'm a rookie at rooting and have an unlocked Japanese Note 3 through AU (my Japanese service provider). I was in a rush and paid someone to unlock it before heading back to the States last year. The phone works with my AT&T sim card but when I am back in Japan (with Japanese sim) I am constantly being dropped from the network. 4G service usually works for internet, etc, but I cannot make/receive phone calls and only occasionally can send/receive text messages. I need to know if I should re-root the phone (and leave it rooted) or just do a factory reset (or perhaps change some other setting to get things working again)? The problem with a factory reset is that it will probably re-lock the phone and I don't have a code.
Strange Detail:
Whenever I try to dial a number, the name of a Chinese Province shows up under the Contact's Name. This suggested to me some network issue where the phone somehow thinks it's in China (though texts still kinda work...) and doesn't connect correctly to the Japanese network.
Details:
Model: sm-N900J (per the download screen) i believe this means it has a SnapDragon Processor
Knox warranty has been tripped (apparently by the guy I paid to unlock it originally - is that bad?)
Android 4.3 (looks like I'm still in the original version of Jellybean. Should I upgrade to Kitkat or Lollipop?)
Other Issues:
As of two days ago, the phone now restarts after about 5 minutes of use. Like many Note 3 phones, it's always done the occasional random restart (another reason to root?) but now it's making the phone almost unusable. Also, since having the phone rooted/unlocked/re-rooted I always get a series of warnings upon start-up. Typically, standard Samsung apps like S Planner, Calendar Storage, Keyguard and Index Service have stopped. I have never been able to use the Calendar (or other basic apps) since it always crashes. Is this an issue with Knox clashing with something from the original root (I still see SuperSU loaded -but "turned off"- in the apps menu)?
Idealy...
...someone can help me decide the best course of action (Root, Reset, Other), and how to make sure I can connect back up to my Japanese network properly. I think I'd prefer to root since what I want is an unlocked phone that works smoothly, with good battery life, little to no bloatware, a custom theme and a working S pen. If I root, what's the best method (already have SuperSU apparently) and which ROM and version of Android would be the most stable?
Main Issues Recap:
No connection to phone network (or limited 4G internet).
Phone restarts every few minutes.
Many Apps crash upon Start-up.
Thanks in advance!
So, here's an update that someone with a similar problem might find useful...
Japan uses CDMA for voice and GSM for LTE Data. Somehow (probably through using my phone in the states on a GSM network) the phone was no longer connecting to the CDMA network. Since I'd gotten no responses and felt like there was a good chance that a factory reset would not reverse the sim-unlock I'd stupidly paid to have done, I did a factory reset. Despite appearing to have solved my Index Service, Calendar Storage, S Planner crashing issues, I was still having the exact same problem of LTE working but no CDMA network.
Somehow I stumbled on to this website...(well, I'm unable to post as a new user but searching for "How To Fix Samsung Galaxy error while searching for network" should bring it up).
There, I found some really odd directions that solve network error issues. The only part of the instructions I was really able to carry out was take out the battery and simultaneously press the home and power buttons 10 times. I restarted my phone and miraculously was able to place a call for the first time in a year in Japan!
But then I no longer had any data. I figured it had to do with the APN settings being wiped in the strange reset I just tried. But when I went into Settings>More Networks>Mobile Networks there was no longer an Access Point Names option in the menu. There is no longer a "Network Mode" option either. I used to have that set to LTE/WCDMA/GSM but now I only see a System Select option that simply lets me change my CDMA roaming mode from Automatic to Home Only.
I tried searching everywhere for the missing Access Point Names menu to no avail (and almost attempted to try flashing CyanogenMod for the time hoping this would bring back the APN settings menu) but then I realized that I could do a search in the settings app. I searched APN and the option came right up (though it's frustrating that this now appears to be hidden). Using the following settings (copied below) from the AU by KDDI website I created a new APN profile. Now mobile date appears to be working just fine too!
So, now I just need to decide if I want to keep running Touchwiz in Jellybean or use my new found confidence to try rooting and custom roms...
I'm also kind of curious to see that the next phone bill comes in as expected and I'm not being charged for a bunch of crazy usage! Also, any suggestions to help explain how I got into this problem in the first place, or how to clean up any loose ends would be appreciated.
