hi,
i have a issue with my xperia j (unknown network); i searched all this forum (before writting this thread) and i found some topics about unknown network but in my case i think is a lil different.
so here is the case:
xperia j, unlocked, rooted etc... (using 4.1.2, 3.0.8 fxp, cm10)
i used for weeks my Orange sim card with it (w/o problems); on new year night (cause of too many sms) i turned plane mode on. in the morning when i turned plane off, the phone was showing me "unknown network | orange"; (reset-ed, cleared caches etc); each time i turned it on there was no promp or other err about the sim except unknown network (but it can see it is orange). also the code *#*#7378423#*#*. is showing me nothing (looks like the popup appear but get close right away).
- works fine with other network operators (i tried 2 more sims from diff operators); but doesn't work with orange anymore.
- also, my sim not workign in other phones as well
i can't understand why the phone works with 2 other operators but not orange anymore.
but also why my orange sim can't be seen in other phones (phones that are orange as well).
if i try revert to stock ttf... will might solve phone unknown netowrk issue? but what about sim? both issue have same resolve or they are diff problems?
any advice, hints will be helpfully.
thank you

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.
As the the title suggests,
My dad's boss purchased this phone and while it works with any sim you place in it, upon turning the phone on, it basically summarises the following,
You have inserted a USIM that is not part of LG U+, and as such will be data locked.
(not word for word quote)
Now I take this to mean that the phone was carrier locked to Koreas LG U+, but the phone works here, and phone calls, and 3g speeds, but no 4G/LTE.
The current firmware version on it is 4.4.2 with I believe G900LKLU1AND3_G900LLUC1AND3_LUC
Now I've tried many different things to try and fix this;
I've read that 4.3+ version is bootlocked, (not exactly sure what this changes)'
I've tried flashing an Australian SM-G900I firmware (thinking the bands will be fixed, as its a software not hardware issue as far as I can tell)
Upon trying this, Odin throws a failed error, the download mode on the phone freezes, I can reboot it, and it's all good and dandy.
I then looked around and found that its possible to put in a SIM unlock code, however I query how that would work as the sim already works, just not LTE/4G
I tried Chainfires Region Unlocker (yes I know it said only tested on Note 3), which said succeeded, but actually did not enable 4G.
And I also saw a rumour that, if you place a phone call for 5+ minutes it will unlock said phone restrictions. In the phone logs it does show a phone call occurred previously before this phone was purchased, not sure if it was 5 minutes, but this may have been the case.
I'm stumped as to what can be done to flash this phone (or whatever can be done) in order to force it to allow the LTE/4G Networks,
Just to re-cap for the tl;dr,
4G/LTE not connecting as the phone mentions it restricts it due to being a NON-LG U+ SIM upon turning the phone on.
Please help ?

Hi
I also have g900L and had issue with LTE at the beginning But I resolved the issue by the following;
Please dial 319712358 and they will show you a box where you need to enter password then enter 0821.
This will lead you to the hidden menu page where you can find network mode where you can switch it to 4g mode.

I will pass this info on to the guy that owns this phone (my dad's boss) and hopefully all good,
Thanks man ,
Will post back here once I find out if it works on his phone.
Hi, just wanted to let people know I've had this same issue. Bought a G900L online and the network would connect to Optus' 4G/LTE for a few minutes at start up then will automatically go back to 3g. The solution above seems to have allowed my phone to lock to the 4g network.
Thanks
Hi All.
I got the dual sim version last week & got myself a new nano sim card from Vodafone. Believe me, they're not easy to find in India.
So I put the sim in Slot 1 & waited for activation. But even after getting the activation message on my alternate number, the phone shows a "x" icon next to the signal meter.
I tinkered around with the network modes, basically trying the various combinations. Even played with the Network options in the Testing Mode. But still no luck. Finally, i switched the sim to Slot 2, and behold! I have reception!! Worked like a charm!
But then i find out Slot 2 doesn't support 3G/HSPDA. So i wanted to try and get Slot 1 to work again. Tinkered around again with the various modes, but to no avail.
The worst part is, now even Slot 2 has stopped working!!
I have no clue whats happening here. Is there a particular network setting that i'm missing, or am i dealing with a dodgy sim card??
Any help & inputs are appreciated.
Thanks

Got a replacement from HTC. Messed up "capture unit"
I'll try to keep this post as simple and well typed out as possible...
I cracked my screen and essentially damaged the digitizer as touches couldn't be registered at all, so I ordered a newbie off Aliexpress and using the guide on iFixit, I repaired it myself. It booted perfectly and everything works fine EXCEPT for a weird issue I'm having with my cellular data and the network itself not registering properly or something.
I've a SIM card and plan with Vodafone Australia and basically the phone:
- sometimes registers 4G/LTE, but never 3G and 2G didn't seem to want to work
- can sometimes send/receive texts (at random)
- can't make or receive calls
- cellular data absolutely doesn't work at all, nothing will load. I think there was only 1 occasion where half a web page loaded, but that could have been cached
- when the network 'disappears' either I just have a blank network bar in the status bar or sometimes I also get a triangle in the status bar and in the notification pull down area it reads "NO SERVICE - selected network (Vodafone AU) unavailable"
- I also occasionally get a warning that says "Restricted access changed - Data service is blocked" - I called Vodafone and they said there is no blocking or barring service in place on my SIM/service and that the SIM should work with any device it's in
- the device even shows details like signal strength -95 dBm and 43 asu, shows Vodafone AU as my network and even automatically loads the correct APN settings
- I tried an OPTUS Australia SIM and the same thing happened, registers network, shows signal strength, APN etc, but nothing works!
Prior to doing the repair I was using a Telstra 4G SIM and everything worked flawlessly right out of the box. Never an issue. I'm pretty sure both providers even run on the same bands.
I have tried the following to solve the problem, to no avail:
- different ROM and kernel (stock CM11S, Temasek CM12 w/ AK kernel)
- fastboot erase modemst1 and modemst2
- different modems (44S, 05Q)
- changing settings in *#*#4636#*#* menu (LTE/GSM auto, and the rest)
All I have left to try is to go see my provider and request a new SIM.
I'm thinking maybe something happened when I disassembled the device, like I may have damaged the part of the main board where the SIM registers. Could this be the cause? Surely not,as I do get that temporary LTE registration...
Also note that I'm 99.99% sure it's an international device, not a Chinese one, as it came with CM11S and the Aliexpress seller told me so.
Any advice? HELP!!!
Never mind. Realized I hadn't connected the antenna back to the main board. As I was putting the main board back in, I tore off the flex cable that connects the volume rockers to the main board. I now have a 1+1 with no working volume buttons. What a waste of 5 hours and a few hundred dollars. That'll teach me to DIY.

That just teaches you to be careful. We have all done it from time to time. I tore a bunch of flex cables in my time. Now I don't. It is all a learning process
Similar Problem
I have a similar problem. After replacing my screen I have no service unless I have line of sight to a cell tower. I mean REALLY close, and stepping behind a wall will make the signal disappear entirely. I'm assuming there was damage to the antenna in some way, does anyone know where I can get a replacement antenna or have any other solution for me? Everything is connected properly, no apparent damage, works great IF I can see a tower and am in close proximity.

Similar problem here.
After replace my screen I got poor signal. The reason I replace the screen is because of water. I still get signal but not as good as before. I also lost signal sometimes. I wonder if it because of the water too.
I don't think it's because the flex cable. I've double check, the cable is attached correctly. I've tried to unplug the cable and turn it on. I can see the difference, when the cable is unplug I got no signal at all. If it's because of the water then which part should be replaced?
Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:
Factory reset
Reinstalled CM
Put paper under the sim for tighter fit
Turned the radio off and on and restart phone
Change pin code
Replace sim-card
Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)
Total restore by fastboot-flashing
Installed OxigenOS 2
Tried all modems from the modem collection on CM and Oxigen.
Retyped the APN by hand
Opened the phone again and checked that all cables are connected well
Tried manualy connect to my carrier under Network Operators
For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.
I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!
If imei present you can try mobile phone exchange offer on flip kart like online stores. When this happened to my phone I did it , very easy.
Sometimes opo dont search available network or wont register on any network.
Sulution: go to access point and reset it to default first then go to network and try to search for network n if ur able to search then try ro register manually and if it does not work then go to dialer and dial *#*#4636#*#* then click phone info and select the lte/gsm ato prl mode and then click turn radio off and again tuen it onn then smsc refresh and update ( i dnt remember it correctly) if that dnt help then ur network antena is damaged
