Hey guys,
Yesterday I was playing around with some Launchers. While doing so, I noticed my signal disappeared and my phone couldn't find a signal. This is pretty normal in my room, as I have a bad signal here. But later on I found I never recovered my signal, and when I tried to search for a network I got the error, "Please insert SIM to use Network functions."
So I was like, "crap I broke my phone!" It's been a whole day and I still can't get a signal -- or rather my phone still can't detect the sim. I tried using the sim in another phone (Samsung I780) and it worked perfectly. I then tried another SIM in the Tab and it couldn't find it either. So I conclude the issue is with the Tab.
Now the question is: is it a hardware problem or a software problem?
I tried a Factory Reset but no dice, same problem.
I'm on stock ICS (Austria ROM) with Root, flashed via Odin, added Google Now with the fix here in this forum. It's a P6200 16GB with 3G of course.
Could this be a software problem? I doubt it's hardware as the Tab is pretty new, only about 6 months, and I don't change SIMs at all. There's no chance that the sim slot got worn, but you never know.
I'm thinking it's the fooling around I did with the ROMs. In particular it might have been Go Launcher EX wtih all those stupid plugins like the one that lets you turn off system processes. I uninstalled all the Launchers I tried but somewhere in the middle of doing so the signal disappeared and this is when I assume some kind of driver for the sim slot got nixed.
Another thing I noticed is that my PC or my laptop can't detect the phone anymore when I plug it in. This only happened today as well after playing with the launchers. So I'm thinking it's not just the sim slot.
I'm going to try a reflash of my ROM again via Odin, but while I'm downloading a ROM I'd like to get your opinions on the matter, is it really a software issue or is the hardware broken?
Man, when it rains, it pours. Had a bevy of issues this week, including both of my internet connections going down explicitly, so I have no broadband. I am typing via my phone's sim, which I had to pop in to a USB dongle.
Anyhow, here's what I've gathered:
My phone's baseband is corrupted. I have a "Baseband Version: Unknown" thing going on in my Tablet. That's probably the source of my woes.
But my other problem is that I can't connect via USB to my PC no matter what I do. Does the baseband also affect that? I can't even update via Odin. I'm trying to figure out a way to update this either by WiFi or by MicroSD. Is there a modem.bin file that we can flash via CWM or 3e or some other updater in Power + VolUp mode?
If I can't find one, I'll try going to my aunt's house to use her internet connection via WiFi, might be able to solve everything through KIES.

Hi,
I am facing network connectivity issue since the time I entered roaming area on my Matrix 2. It does not connect to network. It keeps showing no network, then for 2 seconds it shows emergency call symbol , then for 2 seconds it gets connected to network and again it keeps showing no network. This cycle keeps on repeating.
I searched for the issue and found that it is issue with atrix 2 software and the suggested solution was to install app called network and choose gsm only from it.
I tried it but it doesn't works for me.
I am able to make a call if I dial number exactly at the moment network appears for 2 seconds.
The only temporary solution I was able to find was to dial self number as soon as network appears and then keep on dialing it for around 8-10 times. Then it gets connected to network for 1/2-1 hour and then again it gets disconnected.
Please let me know if anyone has any solution for it.
I am on JB unrooted and using 2g network.
1) Try another SIM ....
2) try flashing ICS radio.img ...... (you shud know some fastboot commands) search the forum
3) try factory reset or reflash JB ..... it might work sometime
if you are using BSNL ..... then i have my sympathies with you :silly: lol
First off wrong forum, should go here http://forum.xda-developers.com/forumdisplay.php?f=1771
Go back to Stock ICS via RSD Lite 6, try SIM with other phone first and check, do not install apps for network improvement as mostly they just turn radio on & off, in worse case they can botch up some internal default settings. Use this for getting a view on network heat range & in particular tower direction to move towards for better reception https://play.google.com/store/apps/details?id=com.staircase3.opensignal&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5zdGFpcmNhc2UzLm9wZW5zaWduYWwiXQ..
Thanks for the reply...
I have already tried that, its not a network or sim card issue. I have tried inserting sim to other phone and it just works fine.
I put it in general section coz when I googled it I came to know that its an issue with every atrix-2 so every one might have faced this issue while roaming.
Also going back to stock have not worked for anyone. Its an issue with atrix-2 software itself.
You seem to have reached to your own final conclusions but yet please understand on JB 4.1.2 leak there has been no one who has echoed your issue (gps is definitely an issue & for some wifi on some particular bands). Also read this http://forum.xda-developers.com/showthread.php?t=1425560
Try flashing the new 4.2.1 ROM based on official leak of 4.1.2 JB as I believe radio is better on it. On JB leak though one thing I can confirm is when phone enters roaming it automatically shuts data randomly and not always & user has to re-enable it. If all fails, fxz to stock ICS and if under warranty claim your stake.
Thanks...will try when I get back to home.
Although I have not reached to conclusion on my own, I search regarding this in Motorola forums and people facing this issue stated that they tried aall the specified methods. They were getting this issue on all os versions.
Please point me towards a link which illustrates issue same as your on JB 4.1.2 specifically.
Heyho,
about three weeks ago, my N5 suddenly lost it's signal over night and shows me "Emergency calls only" and it won't register into any network, just giving "Selected network unavailable".
When this occured my N5 had 4.4.2 stock ROM and rooted. I've unrooted it and updated to 4.4.4, but I still got the same problem.
Problem occurs with any simcard, while simcard works with other phones just fine.
Have deleted and reconfigured APN, but didn't make any difference.
I get a signal every few days, but I still can't receive text/calls or call/text anyone and my mobile data doesn't work.
I even tried to downgrade to 4.4, but that didn't solve my problem either...
I'm from Germany, but in New Zealand at the moment, so I really need my phone in case of emergencies and to stay in touch with family/friends.
I have been searching for a solution since it started, but have not been able to find anything that worked.
Sending it back to Google isn't an option right now because I am travelling.
I am really thankfull for any suggestions or if anyone knows how to fix this problem!
Cheers
Have you checked to make sure the network setting says 2g/3g/LTE preferred. Because I had this problem when it was switched to 2g only and was fixed by the above option
If the above fails trying going to your dialer and typing *#*#4636#*#*. Go into phone information and you should see a drop down box to select your network mode. Play around with those until you get a signal but you might not want to try CDMA options (WCDMA is ok) since you're on a GSM network.
Sent from my Nexus 5 using XDA Free mobile app
had exactly the same issue as you mentioned. Nexus 5 tends to lose network without any logical explanation and it tends to work at one place but stop showing network if you walk half a mile down the road (or may not show any network anywhere). Google has released an update in June in which they have updated the modem to solve the problem..given that I am in India and the June update was for India, Australia and Newzeland, it worked like a charm for me (all i had to do was flash the modem from twrp)..people as far away as netherlands have reported the modem to work for them..
NOTE: IF U INTEND TO FLASH THE LATEST MODEM, DO NOT FORGET TO TAKE A BACKUP OF YOUR CURRENT MODEM PRIOR TO FLASHING THE NEW ONE..
check your sim card. if you can, try someone elses.
Alright,
I've tried every thing again so far, but nothing seems to work.
Sitting in the library, I noticed that I get a signal, when connected to WiFi, which stays for 1-2 hours after disconnecting.
But I still can't make any calls or text and mobile data doesn't work though the APN is correctly configured and and data enabled.
I really hope to be able to solve this problem somehow, don't want to put aside my beloved N5 :/

Edit: Haven't found any solution so far and bought a new phone for the moment until I'm able to send it back to Google.
Might be an hardware issue and not software related.

Hi all,
I'm facing the problem with both phones (Asus 4 Max/ZC554KL and Samsung A10s/A107F). The signal is full, shows 4G, even the arrows, BTSs all around (almost the city centre) but the data connection keeps disconnecting. As long as there's a data transfer (downloads, online radio), it works, once it stops, the connection dies too, still showing 4G/data transfer arrows though. Switching the data off/on doesn't help, the flight mode on/off has to be used to restore the connection. Doing this everytime you touch the phone is kinda....tiring, not mentioning you're getting no messages/notifications till you do it. The sim cards are both quite new (t-mobile cz and kaktus (local lowcost t-m brand)), so it shouldn't be the problem, I was thinking about the problem with contacts to the antennas in back covers as both phones were open few times (was changing the charging connectors due to the slight water damage) but wasn't able to find out if the 4G/GSM antennas are in the cover in case of these phones. The carriers keep saying all is fine from the network part. Both phones were bought new in Asia, being used in CZ now but have all local LTE bands. Asus performs a tiny bit better (in terms of reception) so I decided to dig into the software options. The factory reset didn't help and I realised the phone is still in its original state from the time I bought it (03/19) and offered me zero updates. Even now it doesn't. Tried to download it manually from the Asus website but it always says "error" during the installation and stops it. So I decided to find another way to get it in. Don't want to risk Chinese one-click apps, so I chose Magisk which should allow manual updates with no risk. The collateral problem arose, as the volume keys do not work, so I tried to put it into the recovery mode through ADB. My old computer sadly only has Windows Vista OS and keeps telling me errors whenever I try to perform any ADB commands. Therefore I'm asking you here for help with the following questions:
1. is there any software allowing to put ZC554KL into the recovery mode through Windows Vista?
2. if not, any other way to push any actual ROM version into it? (There's still 7.1.1 from the factory).
3. if not, any other way to get there Magisk?
4. if not, any safe rooting app, not requiring the recovery mode? (Well, I don't need to get controlled by the Chinese comrades)
5. overall, any other possibilities to solve this data problem/keep the data connection working? (I could leave the online radio on (silently) but the battery gets drained quickly and I won't have unlimited data forever )
6. anyone knows where the LTE/WiFi antennas are in these two phones? As Asus has better 4G but significantly worse WiFi reception.
I've heard you're the #1 experts here, so hopefully we'll be able to solve this. If there's any information missing in the problem description, I'm ready to provide it.
Thanks a lot for any help
Hi all,
Got no answer at general Q&A forum so I'm trying it here.

I bought a Galaxy Express 3 (sm-j120a) on Ebay (new condition) to use as a backup phone. I began the setup process and tried connecting to my WiFi. I put in the correct password but it will constantly cycle between showing "Connecting" underneath the SSID, then suddenly the SSID disappears, then suddenly it will reappear and show "Connecting" underneath, etc. It will do this indefinitely and will never connect. If anyone has experienced this issue before and knows how to fix it, I would greatly appreciate some help.
One thing I haven't checked is whether I could update the software of the phone to the last available update. I wanted to hold off on putting in my sim card because I have a nano sim and I think the phone takes a micro sim and I don't have an adapter yet. Is there a way I can download any available updates to my computer, then send the update to the phone via a USB cable?
Thanks!
i ran into the same thing a while back with an old android phone, a samsung j120a. one day its wifi stopped working with the att modem i have, a bgw210. behavior was the same as what you described. every other wifi device in the house worked fine. tried every standard trouble shooting thing you find when you search this, including factory data reset, nothing. got hold of another phone same model... it also failed to connect to wifi on this modem, same thing.
the answer-> i resorted to playing with the wifi settings on modem, and found that the problem was with the wpa version setting- it was set to wpa 2 by default when i found it. i changed it to the setting that accepted both versions 1 and 2, and the phone's wifi now works again.
i assume at some point att updated this modem, and one of the updates was to change default setting on the wpa version, probably because wpa 2 is supposed to be more secure than wpa 1
just replying because i hate searching stuff like this and finding nothing but people asking roughly the same question without getting any answers. hope this helps somebody searching this in future
