Network Not available ON my N 8000 - Galaxy Note 10.1 Q&A, Help & Troubleshooting

Hello guys,
My n8000 seemed couldn't connect to a network.
It has happened since 6 months ago.
The signal shown a full bar, and the SIM toolkit application of the sim card that i inserted is appeared, and also in network setting it show the APN of my network
When i search the network, various network poped up, and i can select the network just fine.
But when i tried to call or do something network related, it always shown "Network Not Available"
I have switched SIM card to various provider but it doesnt change anything
I use
Gnabo v7 ROM,
Android ver. 4.4.2.
And boeflla kernel
My tab has history of "hard modding" in which i used to mess with the efs, broadband and imei number.. but it had been restored
Now my IMEI number is 00499xxxxxx
I think the problem is from software/system related, not the hardware problem.
Is there anyway i can check which component is messed up?
And is there anyway i can fix my problem?
Sorry for my bad english
thanks

First I would check if the IMEI is possibly black listed, maybe here: http://www.imeidetective.com/englishaparativbazi.php
If not I would go back to stock and check if network works.

[Q] Problem : No call, no SMS, but 3G ok

Hello, I have a big problem with my Nexus S Eur (I9023 SLCD)
I bought it used but almost new, and no bill…
The phone, not modified, worked fine for 3 months. (2.3.4 GRJ22)
But one day I could no longer use the calls and SMS, while the Internet connection (3G) worked fine.
The majority of other sim cards are not properly recognized, but mine yes, it recognize the PIN code, the network (Numericable, a French MVNO), and correctly read the APNs. I can go on the net with data connection, but no call, no sms… (No MMS in the subscription I chose)
I tried to restore it with ODIN like I read here, it worked fine, but same problem.
I tried Custom ROM, custom Kernels, I tried ALL the radios of the I9023, no change…
When I call, no error it just hangs up the phone.
SMS, it says sms was not sent
The only one error I can read is, when I want to consult the call forwarding settings : “Network or SIM card error”
Any idea?
If the phone is a stolen one, and if the IMEI is blacklisted (3 months after?!?), is it normal that I still use the 3G connection?
The simcard work fine in my old phone
Thanks !
PS : sorry for my english, I do the best I can
No idea?
Maybe Hardware problem?
is the phone rooted?
try the *#*#3646#*#* to select your correct baseband settings.
When the problem started, the phone was rooted
After, I tried rooted and unrooted
With the 4636 I can access to the list of the baseband settings (now GSM/CDMA Auto (PRL) ), but if I change it (GSM only for exemple), it is not saved.... It doen't say anything, but if i quit the 4636 screen and return to it, it is GSM/CDMA Auto again....

[Q] anyone getting sim card does not allow connection to this network?

I have gotten this message 3 times in the last 5 days. Each time I need to do a reboot to restore cellular/sms service (toggling airplane, wifi, bluetooth, sync, and 4g do not restore cellular/sms). The phone has the same AT&T sim card since day 1 and I have never removed it.
Is this a faulty phone, sim card or both?

Did the sim come with the phone? ATRIX 2 needs newest of sim cards to function properly. If that's not the problem then I'm not to sure.

Yes, same sim card that came with phone.
Could be a faulty Sim, i've had that happen before with other phones, just go to at &t and show them the problem, they should replace it for you!

I wasn't able to solve this problem about an year. But did. And totally sure that it is Device's defect (in some cases it is a ROM deffect as in my case, in other - hardware. Smth like stack overflow issues at GSM controller or so). A year ago when I had face this "sim card does not allow connection... " problem, there are no google serch results on this keywords request. Any. To remove this message I was ought to reboot my device every time it appears. And I was thinking that it is normal behaviour for my device. But now there are lot of complainings at the web ( minimum 5 of Galaxy Tabs P1000, thousands of HTC Disire, few motorolla Deffy, 10 Galaxy Ace, few of Nexus S and so on), so I understand that I'm not alone, and problem is known. So I went to Samsungs Service and they confirmed that it is famous problem, have flashed my phone with some magic ROM (magic because it is official but does not available anywhere in the web, XDA or samsung sites! ) and now my phone works fine. Any other solutions like battery removing, *#*#4636#*#* sirvice menu, new sim-card, flashing variety of modems and roms, didn't helps me. This is not faulty sim. This is serious device's defect. Bring your phone to manufacturer and let them repair it or give your money back. This is their problem not your.
using old 3g prior sim card
With ATT---If you took your old 3g sim card out of old phone and used it. You will get this message. You need to activate the 4g card that came with phone

I have exactly the same issue randomly at times when I try to register on network manually (MTNL Dolphin 3G - Mumbai). Unrooted MB865 ver 2.3.6 & updated on 18th May 2012 to System Ver 55.28.37.MB865.AsiaRetail.en03. If I keep the setting as Automatic in Type of Network & Operator it functions fine fluctuating between Dolphin for local access & CellOne on roaming access in the same area based on cell tower connection the phone registers on alternating between "E" & "H" automatically based on cell mast direction proximity, however if I select 3G only and uncheck automatic for operator then the phone searches for signal for a very long time and fails to show any operator saying "no connection available" & sometimes when "Dolphin" network does appear and try to select manually get the error as "this sim card does not allow connection to this network". I did complain with the service provider and they were supposed to get back to me after checking in their switchboard exchange where I also provided them my SIM number in addition to my cellphone number(no response). Also as is case with poor service of all Indian cell network providers even in urban cities, also face random peculiar issue of call not being received inspite of signal available on the phone & network asking me to recheck the number I have dialled while placing outgoing calls though it is ok and signal is sufficient. Also "Network Speed Booster" app looks like a lot of bull (any other good apps??)
I needed to know using the secret Menu *#*#4636#*#* for 3G GSM service which kind of network I should ideally select for best results & does this setting override the regular menu network settings??
I get "G", "E", "H" randomly based on my locations but no "3G" or "H+" and further at times these icons are grey and sometimes blue and in either cases randomly at different locations sometimes data throughput is not there as only one of the arrow shows active blinking. Any advise on the status based on colors and the blinking of the arrows?? Thanks!

I called att, and they asked for IMEi, phone number and all that, tried to help me somehow, but none of that stuff didnt work, and they said that its probably problem with phone. Does anyone can help me with this ??
Try resetting to default the APN.
Go to Settings/ Wireless and network/ Mobile networks/ Access Point Names/ then Menu button and select Reset to default.
If that doesn't work...what does it show underneath Baseband version ?? If nothin- then flash a modem. If somethin- then flash a different modem.
Hopefully one of these will help ya.

try a factory reset with the sim card in, it should pull apn settings from sim.
flash one of Stock ROMs, they come with AT&T APN preselected.
SauromKK4 "one-click" for example.

[Q] LG Nexus 5 fails to recognize celullar network

Hello,
I have a Nexus 5 phone that came with Kitkat a few months back. The phone worked without issues until I decided to update to Lollipop 5.0 (OTA update) at the end of November. Initially the phone started to have troubles to detect the network at certain times - typically "playing" with the settings "Preferred network type" by changing from 4G to 2G, restarting, letting the phone detect the network on 2G mode and change back to 3G or 4G would fix the problem. The issue became more and more frequent until a point where i can not change the "Preferred network type" from 4G to any other type (as if it is "glued" on that setting). At this point my phone does not recognize at all the cellular network but It does seem to recognize the SIM card since i need to enter the 4 digit code to unlock SIM and it displays the network name, just no service.
I've researched the internet and I've tried several things but nothing seems to fix it such as restart mobile, change to airplane mode and back, take out and re-insert SIM card, request new SIM card from operator. The APN settings seem to be OK.
I've noticed that a new 5.1 version just came out and although I was not fully familiar with the process i decided to give it a try (after reading several instructions) and update manually (using factory images posted) and see if that would fix it. The phone is now with version 5.1 and still can't recognize the cellular network - no service. Everything else works fine, including Wi-Fi.
Has anyone experienced such issue after OTA update? The only odd thing I can think of is that I did the initial OTA update to 5.0 in US while i was on travel from Europe, but I can't say if this would in some way contribute to the issue. The mobile is D821 model.
Since I was stuck and mobile is within warranty period, I have sent it to service repair. I would be interested to know ideas of what could be the issue cause.
Sorry for long message, any help would be very much appreciated.

Mobile Network Not Available

Hi folks,
This is my first post on here. I'm having a problem with my phone which I think is quite unique and I hope someone on here can help me fix it before I buy a new device.
I have a galaxy nexus (maguro) running cyaogenmod.
Previously I was running CM11 (cm-11-20141115-SNAPSHOT-M12-maguro) from the CM website and updated it to CM12.1 cm-12.1-20160719-SNAPSHOT-YOG7DAO8DL-maguro) a few weeks ago.
When I rebooted my phone it was running very slow (and getting very warm) so I did a factory reset and re-installed CM12.1.
It started working ok but I noticed that my phone was displaying 'emergency calls only' even though the network reception in the status bar was full, displaying 'H' (3g) and allowing me to connect to the internet using 3G.
Whenever I make a call it states 'Mobile network not available' and I cannot send text messages.
I tried phoning O2 and they gave me a new sim but the problem was still happening. I then tried putting my girlfriend's EE sim into the phone and I could make calls/send messages. I also went to France on holiday and could use my phone to phone/text using my O2 sim abroad. Whenever I put my O2 sim into another phone I can make calls and text.
So basically it is only when my O2 sim is specifically in the Galaxy Nexus that I cannot make calls/send texts but can still use 3g.
Oh yeah when I go to Settings>Mobile Network Settings>Network Operators the following available networks are shown:
O2-UK
T-Mobile UK
3 UK
vodafone UK
Orange
When I select O2-UK is states 'cannot connect at this time. Please try again later'
I've tried re-installing the older version of CM11 and today I tried wiping the entire phone (internal sd card etc) and it is still happening. Can anyone help? Is there something else I can wipe, or setting I can change?
Thanks in advance
