I lost all signal in my cell phone coverage. I cant call or sms anyone.
I installed the Amberhome Custom Rom v1.1 and all my signal's gone.
Does installing a custom rom screw up signal like this?
where are you located?
Canada, Ontario
Probably the same issue I had with the telus milestone.
When you flash a new rom, it doesn't have the right 3G settings for some reason. You'll need someone to send you those files.
If my theory is correct, your phone works with GSM but not 3G right now. Since Telus does not have any GSM network, it won't find any signal at all.
I'm going on theory here.
Here's the info from the milestone thread
http://forum.xda-developers.com/showthread.php?t=734802
Radio Band Requirements for different countries
Some countries require the original 3G files of your current ROM to work ie. Canada, Brazil, Venezuela, Germany and some others countries uses a different band for 3G. If u dont backup the 4 original 3G Files and restore it over this nandroid once installed u gonna have poor signal, sms problems and HSDPA loss (even if u set apn and get conection its gonna be crappy one).
Files should be in the /system/etc/motorola/bp_nvm_default/ of your phone.
Files can only be copied from OpenRecovery , using adb shell.
Latest v0.5 has builtin install option using GScript , so you can get the radio replaced/installed. without update zip files.
You might check this thread , if a update-nosign.zip file exists for your model. which makes it easier for you to install.
Filenames are:
File_Audio
File_Audio2
File_GSM
File_Seem_Flex_Tables
generic_pds_init

EDIT: since these are motorola instructions, they probably wont help you, heh
Im not even using 3g i only have a prepaid account
So you're saying that I cant even use GSM? and that Telus has different GSM files than the rom?
Telus has no GSM/GPRS/EDGE coverge. It has an UMTS/WCDMA/HSPA network. However, unlike most of the world, it is on the 850 and 1900 MHz frequency bands instead of the more common 2100 MHz.
So it is possible that you flashed an update from the rest of the world that messed with your radio configuration.
I solved it
my phone mysteriously came with the "only 2g network" checked in the mobile network settings
i unchecked it and i have signal!
You can also set your phone to "WCDMA only" so that your phone doesn't try to connect to any GSM network.
I recently got an unlocked AT&T Atrix off eBay. I was mucking around with the *#*#4636#*#* menu trying to fix a minor connectivity problem where I couldn't connect via UMTS, and by the chain of unfortunate events I managed to set the frequency to USA band. Now, since there is only USA band to select, I can't set it to any other band, I am in Australia and only pick up 2 other networks which are not mine.
Is there anything I can do to get it back to the unlocked state so I can find my network?
I remember with my Galaxy S, there was a recovery mode that could wipe everything, is there anything like that with the Atrix?
Thanks in advance!
I don't mean to sound asinine but can't you just do the same thing and select the correct information?
You could also do a full reset on the device or flash it too.
No, only the USA band is there, I cannot select anything else It came unlocked already so I'm not sure how they did it.
I'm hoping there is a way to fix this without resetting or flashing it.
If it comes down to it, is this the most up to date flashing guide? http://forum.xda-developers.com/showthread.php?t=991072
Thanks again!

Select Android Recovery
Click right bottom of screen

Then you are all clean
If your phone is rooted, you can manually input the proper carrier information in
settings > wireless & networks > mobile networks > access point names
A quick google search or call to your provider should be able to get you the information you need to enable data
On the other hand, the AT&T Atrix doesn't support UMTS 1700/2100, so if that's the band your carriers run on, you're SOL trying to get 3G.

actually the AT&T atrix supports 850/1900/2100 UMTS bands so it does work for overseas carriers that support 2100
im actually using it right now in Hong Kong and they use the 2100 band for 3G, no problems with data at all
apparently the OTA update fixed your issue with the USA band for some people who had the problem. i think they did as follows flash to the retail sbf, than let everything stock, get the update over wifi install it and the radio worked again.

No this method doesn't work ..
I was in a similar situation 2 days ago. So, the first thing i tried was do a Android recovery. After this method failing, I went to the last stop, Flashing of the 4.1.26 SBF.
And I jumped with joy to see my Atrix seeing the GSM signal again.
I had 3G before this had happened so I know it worked on my network.
So just follow this guide and I will have my GSM signal back again?

Assuming you are using Telstra (same as me) have you used the mobile configuration page? Support the ATRIX
configure.telstra.com.au/telstra/index.jsp
It might, but requires the phone to be working first, as it SMS a password to gain access ot the site!

Correct, I should have stated it was an intended fix if he hadn't of fiddled with it (i.e. his connectivity issues) as it installs all the correct APNs and settings for you (However it does not add default,tether - just default so be sure to update it for tethering)
you should put [SOLVED] in the title so people know where to look for the same problem ;D
Howzit,
Could you show me how did you do that?
I'm new using andorid and I dont know how to do this procedure.
Thanks.
I recently bought the cell phone in US and am visiting India for a couple of months. When I tried using the GSM sims of both vodafone and airtel in in India I wasnt able to make any calls or rceiev any sms, despite of this being a WORLD PHONE.
I even rooted my device and by installing the APN MAnager I was able to install the Vodafone settings and to my surprise
Was able to get its 3g/Data services working.
However the Voice or the sms is still nit working.
The signalbar is showing just fine and so's the data connection symbol. However with the gsm sim in I keep gettin this NON VERIZON SIM ERROR icon on the top left.
Under the settings>MOBILE NETWORKS ive tried changIng them to both GLOBAL and GSM but still no luck yet.
Can anyone help me out with a network/sim unlock method, similar ti the ones avaialable on the tmibile and other phones.
Pretty sure the voice still uses CDMA. I believe that Verizon still only uses the LTE/GSM for data.

If thats true, then it wouldn't truly be a global phone now would it? GSM will work for voice, but you still need verizon's permission. It should work with a verizon sim, but you will pay through the nose. Now I thought the SIM was unlocked but I could be wrong. Also, even if it is unlocked, it still needs to be compatible with the network frequencies. I don't know what frequencies the VZW S4 has but you can google it.
This being a Dual Band mobile These are the bands that it supports..
CDMA 850
CDMA 1900
GSM 850
GSM 900
GSM 1800
GSM 1900
LTE 750
LTE 1700
WCDMA 850
WCDMA 1900
WCDMA 2100
Also on googling I came across some posts which said the people have managed to use there gsm sims in europe n korea and were able to get the voice n sms. For data they too had to play with th APN..
So what I am tryin to make out from this is we don have a solution to get the voice n sms working on gsm network
Pic showing the error message that I get when I try to make a call.
The second oic shows how my Network signals and data signals are showing just fine but still am not able to make any calls or sms.

I used my phone and put in a Straight Talk (AT&T) SIM and it works with data and voice after manually putting in the APN. If Verizon phone works on AT&T network, it should work with any network out there provided that the bands are supported by the phone.
I was under the same impression, as it worked for me too when I used the tmobile(gsm) sim with it. I was able to make calls only and data was restricted.
Where as with Vodafone IND its the other way round. Am not able to make/recieve calls or sms but data 3g is working just fine.
Confused what could the problem possibly be.

If rooted, you can use Titanium backup, and freeze 'Setup wizard'.
What good would it do if I freeze the setup..how do you suggest I proceed further after freezing..?

I recall needing to call verizon and get an unlock code for my old droid 2 global so that I could use non-verizon global sim cards in it. I believe you just needed to be a customer in good standing for at least 10 months, and could only do it once a year per line, or something.
Edit: A quick search showed a post claming it is already SIM unlocked, so never mind!
Since only my Data is working on my VZW GS4, that too after rooting and installing titanium and apn Manager.
Just wanted to confirm if I am thinking in the right direction, Is it possible that I may flash the Stock Rom for I9500(international Version) in my vzw GS4, and it would work with any international carrier around the world, cos currently am only able to use the Data/3g and Neither Voice nor SMS is working out here for me for GSM carriers like Vodafone and Airtel.
Id really appreciate if anyone can help me lookup a workaround for this..
I just made to run my port of Android Revolution HD 2.0 for i545 (I was porting it from i9505). Everything is working, except CDMA-networking. It's multilingual as well. If anybody wants - I could give it to test. I asked mike1996 for permission to port it, so it is permitted

Amaze is compatible with frequencies:
GSM:
850, 900, 1800, 1900 MHz
UMTS:
850, 1700/2100, 1900, 2100 MHz
Data:
HSDPA+ (4G) 42.2 Mbit/s, UMTS, EDGE
Have you had ANY phone work on the idea network properly? Same with the airtel?
For starters, switch from WCDMA only to Auto or GSM/WCDMA.

How about ask your local service person for the correct settings, or hopefully someone on this board who lives in your area can post theirs.
Is there an OTA specific to your phone?
While not the case with you currently, it may be important if you travel--there are some areas where certain carriers don't have that coverage:

Aircel uses 900 and in some places possibly 1800. Do you have a data plan? Have you spoken with a support person with any one of your carriers--they're used to things like this and getting in the proper settings. I would strongly recommend that.
Check the Settings->About Phone to find out which version of android you have, and if you are running a custom ROM or not.
Do all of that first--make sure you have a data plan, speak with a support person, find out a little about your phone.
If you are stock check with your support person if there is an upgrade for you, also.
If you are NOT stock, you might want to go back to the Stock GB or ICS (remember to update the radio also) so your phone will be basic and stable, to be sure it will work at all with data. Once you've determined if it will work with data, then you can try one of the custom ROMs if you like, but NOT JellyBean or KitKat, as they are all problematic.

I think it should still work. The tech should be able to give you settings regardless of the device origin--you're still paying for a plan, and some support should come with that.
Nevertheless, check this to make sure you have the right settings.
You "may" also have to call T-mobile and ask for unlock code for your phone--they will ask you for the IMEI.
I don't know if necessary, but have read something to that effect--that in using the Amaze 4G in another country, you need to have the phone unlocked. I'm sure someone else on the boards here will let us know.
The back cover houses the antenna, and yes, it could be the antenna, but unless you have another back cover to test it with, it will be best for you to check the settings first, and then see if it needs to be unlocked.
Then come back here with what you've learned--it'll help me learn too.
The ad said that the phone is unlocked... I purchased it from Ebay and I have a prepaid connection with the provider.. it is "pay as you go plan" so I guess they wont provide much help as I have seen customer care people putting their hands up many times saying it is a problem with the device and they cannot help...that's y I was trying to get some help here on the forum as someone else could also have faced the same issue and can help me with their experience...

Besides the firmware update, there has been a separate radio update.
I think these are the most recent updates:
Software number is 2.14.531.30 710RD
Baseband version is 1.15.550L.08DC_30.80.550L16D
It's possible that your phone will work with them.

You may be able to just put the official OTA on your exernal SD card and flash through recovery--not quite sure yet.
I gotta see some of the settings info, so for starters go into your settings->about phone, screenshot the page that appears and also scroll down to any new pages, and post screenshots here.
How to screenshot:
http://forum.xda-developers.com/showthread.php?t=1885386
After that, reboot the phone into recovery following these instructions, and screenshot the recovery screen and post it here also:
Power the phone off and wait about 10 seconds after the screen goes black to be sure it's off->hold Volume Down button, while doing so press the Power button, and release both buttons.
The phone will boot to bootloader, should say hboot up top, and have a little list below it.
If you can't screenshot it via the previous method, note if at the top of the page is says Locked or Unlocked, and if it says "S-Off" or "S-On", and note the version of hboot so you can post the info here.
Use the power down button to highlight the list item "Recovery", and then press and release the Power button to enter the recovery. After recovery loads, note if it returns to a screen just like the hboot screen, or if says in it "TWRP", "CWM", or "4EXT" or any such other thing, and screenshot that or get the info and post that here also.
Now that you've learned what sort of state the phone's in, you can reboot from whichever screen you're on, and have your phone back to normal.
Once you're back with your phone booted, you'll find a screenshots folder in gallery most likely, else you'll have to search the phone with a file manager app or google to find it, but check the gallery first.
After that we'll look for the proper update and update method for you.
Hopefully by then someone else will come along and say something like "All he needs to do is download this "Official OTA" [link included] and put it on the SD card and flash it via hboot"--hopefully, 'cause I may be making this more complicated than it needs to be.

You did a good job with that--thanks. Hey, you're in good shape--everything is new enough.
You need to Super CID your phone, and then flash a rom for one of your local (in India) carriers.
Super CID instructions:

ROM for carriers:
Sorry I can't provide the link--I'm having a helluva tough time searching.
Maybe by the time you've Super Cid'ed your phone, someone else will tell us where to find a proper ICS RUU for India.
Thank you
Thank you for taking out time for helping me...can any other rom (other than the T-mobile) working... and I dont know what is RUU..lol.. I am pretty new to these terms.:laugh:

In order to use the phone in your country you need to have one of your carrier's firmware on the phone so it is compatible.
You can't put their firmware on your phone until after you've performed "Super CID". After performing that, other carrier's firmware can be flashed to the phone.
RUU restores the phone to factory condition. Let's not concern ourselves with that just yet--follow the instructions to Super CID.
Hi everyone
I am in the UK and bought the Note 4 Global version, as in the UK my provider uses Band 20
I am on Tesco, which piggy-backs the O2 network
However, on inserting the sim I receive the No Network error.
Tesco give me the usual "we don't sell those handsets so we can't provide technical support blah blah" "It must be locked blah blah"
The sim is fine as it was in his iPhone 5 (and still is because this won't connect to Tesco)
The Mobile Networks setting has been changed to what was on the previous phone, but with no joy.
Any ideas anyone?
Thanks in advance
Edit for stupidity:
Android 7.0 NRD90M
MIUI ver 9.0.5.0
Have you tried any other sim card in the phone? You can get one of those cheapie PAYG sims (for example, EE) from Tesco or your corner shop and see whether it has the same problem (which might point to a hardware issue or something funny going on with your ROM). I am not sure why you would have had to change the mobile networks setting. That should not be necessary at all.

Forgot to mention this is my son's phone.
I have an EE pay monthly sim. Tried that. Same thing. No Network.
Irony in the fact that it says TESCO 4G in the top band by the clock when he puts his sim in the Note 4 and 2 bars on connection.
Cannot ring out and cannot accept a call

Silly question, are you sure it's global version? A lot of "global" word from Chinese phones.
Is this the package?

Ok, it definitely should work with EE, and so this is clearly not a Tesco mobile problem. Either the hardware is faulty or the ROM (particularly the modem drivers) is faulty. You might want to return the phone.

I have the same sticker in the same corner
I had to order the Global specifically for the Band 20 in the UK
Any way to tell if it's not?

Darth, I think you may be onto something. You just triggered something I read earlier
Is this the same issue?

I suppose that the sim card is 4g card, right?

It looks like the same issue (on a different Xiaomi phone). The solution is probably the same - flashing the appropriate modem (firmware) files, or flashing a new complete ROM. I wasn't sure you wanted to go down that route, as it would give the vendor an escape route if something goes awry, or if the process doesn't solve the problem.

His is a 6GB Tesco 4G and mine is a 40GB Virgin/EE 4G
His sim states Tesco 4G in top right, my EE states No Service.
LTE Discovery. What am I looking for in there?
In the Sim 1 section it says:
Band 20
GCI: 00144E78
PCI: 71
TAC: 16624
-110dBm
On Signals it says EARCFN (LTE Band 20)
Just been through my email confirmation and this is the one they sent me
https://www.geekbuying.com/item/Off...Note-4-4G-64GB-Smartphone---Black-379093.html
Now forgive me if I'm wrong but that says HK Stock Global
What's the difference between that and the Global Rom?
Darth, am I going down the flashing routine? Not bothered if I am as long as it works
Jesus H, it seems everything I buy I have to reflash these days.

If the phone sees the signal and it does detect 4g ,than the phone is ok.
The problem is that 110db . That's practically dead zone. I would say your location is the problem. I know you said that Samsung has 2 bars but this is crappy phone .
Just to be sure, can you check in a a place with strong 4g signal?

Believe it or not, Tesco has really strong 4G in my village. Never a problem on that carrier
EE however is ****. I have "H" on their network and -123 dBm
But I don't use my data at home
My main problem lies with the calls and texts not being able to be connected
It seems I have been sent a HK Global Rom? This has Band 20
Is this an issue? I am in the UK. Should I have been sent a Global Rom? But this doesn't have Band 20
Is it the modem driver issue as stated earlier?

It should have come with global rom . I'm not sure though that it would effect frequency.
Try to change from global to lte/wcdma in preferred network

It seems that you will have to go down that route, unless you return the phone. Whether it works or not will depend on whether it is a hardware problem or just a ROM/firmware problem.
By the way, there is a firmware repository here: https://forum.xda-developers.com/showpost.php?p=73534612&postcount=89
This requires you to have TWRP recovery.

Fired an email of to Geekbuying
See if they want me to send it back or give permission to add the modem drivers with warranty intact
Just noticed that with WIFI on it says I have Tesco 4G. When I turn WIFI off I have no service.
Bizarrely, after reading, this has been going on since the Note 3
Strangely, the phone is giving 4 bars for connectivity for calls. Yet you just try and a make a call
It's always my luck when people order from China and get this wonderful, working, all-singing all-dancing product ..... then I order one!

These things are often a hit-and-miss affair, especially when buying from outside the EU. I bought mine (two) from eBay (UK and Ireland based sellers) - much easier to get refunds via PayPal (and more likely to get a proper Global ROM). But it is possible that your problem will be fixed by flashing the latest global stable ROM.
Update
Took it to the Tesco Phone Shop this morning and they couldn't get any of their settings to work. Consistently No Network. Wouldn't even connect to the Tesco guy's Vodafone sim.
Tried a Virgin sim and it wouldn't connect either
Guessing something wrong with the global rom now?
As with Note 3, MIUI 8 and the missing modem drivers?
Sparked an email back to Geekbuying to see what they can do
Thanks all

Possibly - but there is also a possibility that it is a hardware problem. That will only become clear after successfully flashing a complete ROM (global or otherwise). Whether the ROM is global or China should not have any effect on connecting to a phone network (especially EE).
Which version of MIUI are you on? Try updating of there is an update available and see if that helps.
