Emergency Calls Only

Hi All,
Got a GS4 i9505 originally locked to Vodafone, had to downgrade modem firmware to unlock to all networks - put in a Three sim - gives me signal but for emergency calls only - No data, no texts and no calls.
upgraded the modem firmware again - no change.
But a stock rom on - No change
Rooted and put a custom rom on - no change.
Tried a different sim (EE) and doesnt give any signal.
Everything now points to the IMEI being blocked right - Nope, checked that and its not blocked.
So im stuck, any ideas?
Thanks all

Where did you get the phone from? New or used? What firmware where you on and what are you on now?

OP, what country are you in?
The reason I ask is there is no such thing as three in Australia any more, it was closed down on the 31st august.

modem problems...
u need to visit Service Center :sly:
Send my E-960/S4 LTE/N2 GSM and /Galaxy Y to xda

Thanks for the replies.
The phone is second hand - apparently it was "unlocked" for 3 when i got it - even though it had a Vodafone bloatware rom on it.
Im from UK - :/ but thanks for the suggestion.
Its on 4.2.2 - stock rom - it was on a custom rom (not sure what though)
When you say Modem, do you mean the hardware or software?
If it is the modem, how would the 3 sim get signal but an EE sim wont?
Thanks

[Q] Virgin Mobile Stock ROM?

I have a Virgin Mobile S5 - and was thinking of rooting it and a recovery also.
My ROM G900PVPU1ANE5
I see in the Sprint S5 area it will work (I did similar with my VM S II)
Anyway; is there a way to get a backup of my Stock ROM? - There are no V.M. ROMS in the lists (or anywhere I look for that matter) except Canada and it is different.
I wondered about something like Rickys Rom Kitchen to get a ROM BU - I will read that post and see if I can make any sence of it all.
I ask, just in case something was to happen - and without a Stock Virgin Mobile ROM I could not get it back to stock.
FWIIW - My S5 does not seem to have anything Knox on it -
Edit - when installing recovery - it reported knox

There are dozens of firmware repositories, not to mention a links to a lot of firmware on this site. It's difficult to believe that you did a decent search and couldn't find any stock firmware for your carrier.
Tell us what sites you have checked and what keywords you searched with and no doubt someone will be able to point out a site you missed.

I searched with many terms;
Galaxy S5 ROMS
Galaxy S5 Firmware
Virgin Mobile Galaxy S5 ROMS
G900PVPU1ANE5 <-- Sprint has same number (But theirs is branded Sprint and will likely show a Sprint Splash on boot)
(As I had this same type thing with my Galaxy S II from Virgin Mobile a good while ago and had to use a Sprint ROM)
I will be a VERY happy camper, if someone can find a site I missed! (With my V.M. ROM/Firmware on it)

Since you gave details of actually having searched (most people claim they have, but really didn't), I did some digging for you.
The reason that you are having difficulty finding stock Virgin (US) firmware is because Virgin US is a Sprint MVNO (Virtual Network Operator) that is wholly owned by Sprint since 2009. This means that Virgin US uses the Sprint network and is supported by Sprint vis a vis the Virgin US offices in New Jersey.
As a MNVO, Virgin US uses the same S5 variant as Sprint, the same MCC and the same firmware. Only the CSC, MNC and APN info (and a few branded apps) vary. Moreover, since Sprint is using multi-CSC firmware, the firmware is often tagged as SPR (Sprint) or Unknown when it actually is the original, stock firmware for Sprint, Virgin US and Boost (another Sprint MVNO).
So the original firmware for your phone is in fact the Sprint version. If your phone currently has Virgin US firmware on it, then installing the multi-CSC firmware should retain your correct CSC. If it was me, I'd just do a quick check afterwards.. your CSC should obstensibly be VMU.
SPR = Sprint
VMU = Virgin US
BST = Boost Mobile
.

Tkx for the details ffft
I may just go ahead and root it - and put a custom recovery on also.
I rarely have had issues with my cell phones (Warranty that is)
I just would feel better if I could restore it.
I do not know much at all about Cell Phones and the terminology (I looked up a few of them you have here)
I just found a way to check these (by *#1234# ) and came up with:
AP G900PVPU1ANE5
CP G900PVPU1ANE5
CSC G900PSPT1ANE5
I do not know what the AP and CP are but at least I can check them

AP firmware version
CP radio version
CSC sales code (region or carrier code)
The long CSC is a bit cryptic. But you can use an app like Phone Info to get the more commonly used three character code. Or if you are rooted, you could look at the build.prop file.
.

OK I installed PhilZ CWM Advanced Touch (Recovery) without root.
Then I did a full back up
and also found a "Clone ROM" and did that also
(it makes an update.zip)
Now I "should" be able to root - and if something happens flash the ROM I made with PhilZ's CWM
** See below Post - it does not stick when not rooted (Unless I did something wrong)

OK I rooted (CF auto root)
And I still show the Virgin Mobile splash
I did have some problem with PhilzCWM until I rooted - it would not "stay" there
I could run Odin and install it and one time boot to it and do back ups
But next boot it was gone
After I rooted - I re installed it - and it "stuck"

All normal behaviour.
Glad you got there. Everything runs better with root The objection to your custom recovery before you rooted was no doubt Knox seeing it as an unauthorized change.

Great thread
Really loving your thread. I just came from a broken s4 to Virgin mobile s5. I understand Odin/root/rom installs/returning to factory stock to update etc...
Obviously Virgin Mobile s5 threads are limited here and would like to work together and update each other.
I got root without tripping knox "not cf autoroot method" but "towelroot" method.
First thing we need to work on is getting the .tar file for odin to return to factory stock if something happens.
With all the updates that will probebly be rolling in soon im reluctant to install a custom recovery because you can't update it "over the air."
Second thing is i have no idea to get a official thread going.

Other thought
I orginally came from a Virgin Mobile Evo 4g 3D and the ROMs was aroma based. There was a specific setting if you had a sprint or virgin mobile phone during the installation. I believe it's about having to change APN settings and whatnot. Need to research this Sprint/Virgin Mobile/ROM duo more and what exactly needs to be changed.
Im confident the Sprint ROM itself is good. Just particular settings, one for example, the APN needs to be switched back to whatever Virgin Mobile is.

Interesting tid-bit the Phone info app shows my Samsung s/n as 00000000000 now
No Country of Origin
Knox Warr = 0x1 (Does that mean knox is tripped)?
Product Code: Not Active
I noticed that there does not seem to be a s/n on it - except for the MEID (hex and dec) and a ICC ID

I updated with Kies 3 to G900PVPU1ANK4
This (natrually) made my Virgin Moblie S5 Stock again.
Then did both CF auto root and PhilZ CWM Advanced Touch (Recovery)
And it all seems to work fine again.

HELP PLS

I need your help desperately! I just got my virgin mobile s5 yesterday and I am new to running Custom ROMs. I rooted it and successfully installed PhilZ CWM Advanced Touch. From here I think I skipped a step in CWM to make a proper backup (yeah I'm that noob). Well I successfully installed Slimkat and got it to run on my phone, but I couldn't configure the APN properly on virgin mobile after countless installations of different "universal fixes" for the vmu apn. Now I can't get it back to the stock firmware! I am downloading the sprint firmware right now, specifically the G900PVPU1ANE5_G900PSPT1ANE5_SPR.zip. I couldn't find virgin mobile stock firmware. Do you think it will work if I flash it on there? If not, do you happen to have a backup to the G900P virgin mobile version I could flash? I just need service again.

To get back to stock try using Samsung Kies 3 program on your computer

Make sure your computer sees the S5

Okay I'll still try a few things. Do you have any backups or know of any roms that for sure work with the virgin mobile data service? I am just running into a bunch of issues with slimkat and if you knew a rom that was compatible with Virgin Mobile and this model of s5 I could have mobile service again! especially if you knew the steps how to do it

Ahh yes I also took these steps to root and download a custom recovery on my phone, which I succeeded in doing. Perhaps I haven't made my problem clear. I have PhilZ installed and everything along with a rooted phone. I am currently running Slimkat but I do not have any mobile service so the phone is useless at the moment. My issue is is that I have no ROM backed up. And look, I'm sorry to pester you like this but at this point I would honestly offer you monetary incentive if you help me resolve this. I'm pretty desperate :silly: I saved up for a long time for this phone and I would really like to use its cellular functions. What ROM do you currently use on your phone and what steps did you take to get mobile service working on it? Thank you very much for your time

[Q] Note 3 N9005 Not registered on the network! This is weird! Please help :)

Dear All,
Trust this finds you well
I have this very unusual problem. I have a Galaxy Note 3 N9005 and I live in Denmark. I havent have any problem with the network what so ever. 4 Days ago, I suddenly realized that I cant make any calls and I get "Not registered on the network". Although I can not make/receive calls, the data seems to be working (3g). I tried other sim cards on the phone and they work perfectly. My sim card also works with any other phone!! I did everything I could find on forums (from flashing new roms to....). I went to Telia store ( Telia is the company I get the network), they tried to reset my number and my sim card, tried new sim cards... but it just doesnt work!! They told me that they havent seen anything like this before. Looks like my phone is blocked on Telia Network!! No Telia sim cards works on my phone but others do!
I have tried new modems, firmwares and etc. The phone is unlocked. Right now I have flashed X-note but its still the same. No matter what Rom (custom or stock) I use, it just doesnt work. Can anyone please help me?? Much appreciated!

Hello, i got exactly the same problem here, i was thinking that the problem was about region lock but in fact it's not.
I tried everything like you, flashing modem, stock rom, custom rom... everything i found on the web and nothing worked for me.... I bought the SM-n9005 1 month ago in france, and now i live in new caledonia, i was able to make call for about 2 weeks without any problem and suddenly, impossible to connect the network. Samsung gived me the region unlock code but didn't make my network work again.
I'm so disapointed. My imei and baseband are correct.
bootlader : N9005XXUGNG1
baseband : N9005XXUGNG1
PDA : N9005DXUGNH1
CRC : N9005ITVGNG1 (audax rom)
Please someone help us !

Hello @yashironc
The interesting thing is that my phone is also from France! I have been using the phone for 6 months and no problem at all! The problem suddenly appeared few days ago. I'm actually considering to change my network provider as it appears to be working on any other one! Hope it will not be the same after some time...

please someone help us

Tried This
one thing can tried is changing the imei number, to a phone thats not connected to a telias network that way it will registered on the network another new phone it looks like your phone got blocked by your carrier

Try this.. It worked for me for my note 2...
Hi I faced the same kind of issue with my note 2 and I found some solution.
1. Download the previous version of firmware from sammobile. ( Eg: If the current version is 4.4.2 you have to download 4.3).
2. Flash the firmware using Odin.
3. After flashing the firmware now update the firmware to current one using Samsung kies.
4. After the updation when the phone reboots your issue may get resolved.
It worked for me. Just try doing that......

Thanks Rafi. I tried this but it didnt work out because when I connect to Kies, it says that I'm using the latest firmware which is strange! Looks like in Denmark, the updates are a bit late. I will try to change my IMEI number, hope it works...

Yes, may be your phone has been blacked list by Telia network. Ask your Telia network to be sure?
But curiously, how can you change the IMEI?

same problem here after afligt

Hi, i don't know if changing Imei will fix the problem because my carrier don't blacklist phone and I have the same problem here :/ I got now a phone who can't make call. Damn Samsung 700 € for that ?

Thanks vndnguyen for your reply. I asked them several times but seems like they havent blocked my phone!! They were in shock like me I finally decided to change my network provider as it was the cheapest and easiest solution. I think if the IMEI number is blocked, I should not be able to receive signal from other providers as well, cause that doesnt make sense in terms of security. Hopefully someone could find the answer to this unusual problem and save some lives Cheers!

Nope, if your imei was blocked, you still can receive signal from your home network, but you can not make a calls.

There is a difference between the two IMEI blacklists.
One is Provider-based. Meaning your provider can block your IMEI on their network alone. Other providers work without issue. They used to do this here for a long time if you used a different device than the phone you purchased from them. It still happens in some countries if the device is from another country or sometimes when it runs a customROM.
Providers are also very good at denying this.
The other is the international blacklist. This one renders a phone completely useless worldwide, and is usually reserved for stolen devices.

Help please, I flashed rom and ruined phone

Sorry, but I am a newbie so forgive me if this is stupid!
1 I had a slight battery problem so decided (why??) to flash the rom on my unlocked S7 edge. I used the 'BTU' version.
2 after flashing rom i cannot make or receive voice calls
3 i went into a samsung store they said it was an unlocked SM-G935F and had 'XEU' firmware.
4 they kindly reflashed this for me but it didn't solve the problem
5 I have just tried downloading and reflashing again with the XEU firmware. But I still cannot make or receive calls
one weird thing is that the odd text seems to get through to me
Anyone got any ideas on how to unbrick my phone? Very much appreciated.
Sorry, one extra piece of information. I am on '3'. But if I put an O2 sim in the phone it can make and receive calls. But before my first flashing it worked fine with '3'.
It seems I must have flashed the wrong firmware but have no idea what was on there. The previous owner used a EE sim in it. But it was bought not locked to a network - i think. There was no network branding on the phone.

Would it be possible to flash the wrong CSC - for example and American CSC - I am in Europe and on European CSC?

I'm really not sure why you suggest everyone to install TWRP? People with less knowledge shoudn't know that flashing twrp will break the knox and they won't be able to use secure folder etc. Please put more information with such suggestions.

3 i went into a samsung store they said it was an unlocked SM-G935F and had 'XEU' firmware.
4 they kindly reflashed this for me but it didn't solve the problem
5 I have just tried downloading and reflashing again with the XEU firmware. But I still cannot make or receive calls
one weird thing is that the odd text seems to get through to me
Anyone got any ideas on how to unbrick my phone? Very much appreciated.
Sorry, one extra piece of information. I am on '3'. But if I put an O2 sim in the phone it can make and receive calls. But before my first flashing it worked fine with '3'.
It seems I must have flashed the wrong firmware but have no idea what was on there. The previous owner used a EE sim in it. But it was bought not locked to a network - i think. There was no network branding on the phone.

Try flashing XEU rom via odin but use CSC file instead of Home CSC you'll loose your data so don't forget to take a backup via Smart Switch.
one more suggestion flash older firmware (again 8.0) from XEU later connect your device to pc and update to latest via smart switch.

Many thanks that sounds like an interesting idea.
But.............. if I go back to the first version of 8.0 (oreo) will it wreck Knox or anything else to do with security. I want to still be able to use samsung pay for example.
Also, i was told by a samsung shop person that you can't downgrade because there are systems in place to stop you. Though i dont know if he meant from 8 to 7 or from recent 8 to older 8.
I am planning to flash this:
https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935F/XEU/download/G935FXXU2EREM/222561/
due to fact that its original software was xeu. Is that ok?
Your help was very valuable thank you

you wont break the knox and you don't have to go that much back just download 2 version back from january or february will be enough.
you can't downgrade your bootloader or turn back to android 7.0 that's what they mean. Smart Switch shpuld fix the problem for you.

Forgive me but I am new to this.
So are you saying:
1. Download:
https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935F/XEU/download/G935FXXS3ERLF/251612/
That's the last but one from January 19.
Which has: PDA G935FXXS3ERLF
CSC G935FXEU3ERKF
2. Can I just flash that. Or must I remove the bootloader from that package and put in the current bootloader?
And I was presuming I would do all of that with Odin??? Am I wrong. Is there a way of doing it with smartswitch? (I have reset the phone and got rid of all of my information already)
update: tried flashing last rom , that didnt work. the one before wouldn't flash - i notice it has numbers'3' in the various codes rather than 4.
still not solved
Many thanks again
Bob

Flash the os via odin (select CSC file not home CSC) Untick re-partition option on odin. (Instructions)
Select all files except home_CSC from odin. BL-CP-AP and CSC
After your device boots, skip settings till you see the home page. Connect your device to pc and launch smartswitch (It could ask you to install smart switch to your device) and update latest firmware over smart switch.

Unforunately, I am getting nowhere. And cannot get my phone to work.
Odin will not let me flash any files which have '3' rather than 4 in them. For example I can flash
BL_G935FXXS4ESC1_CL14843133_QB22373776_REV00_user_low_ship.tar.md5
Because it is FXXS4.... the '4' being the important bit
But I cannot flash:
BL_G935FXXU3ERL3_CL14843133_QB20951136_REV00_user_low_ship.tar.md5
because it is FXXU3.... the '3' being the important bit
This seems to reduce me down to the last firmware for both XEU and BTU neither of which enable me to make calls on '3' network like I have done for months before flashing.
Thanks for all of your kind help
It looks like my phone is bricked (
All the best

Bob, can you flash latest XEU? We are going to get new security patch update in few weeks. April security patch not yet release. If you can flash latest XEU you can update your device to upcoming update via Smart Switch.

Still bricked: cannot make calls
Thanks for help everyone.
I thought I would give you my conclusions so far in case they are helpful to anyone.
1 My phone was working perfectly for SMS, phone calls and data on the '3' network.
2 Because the battery life didn't seem good I decided to flash it
3 It turns out my phone was initially sold with 'XEU' firmware. But I didn't know that and so I flashed it with 'BTU' firmware - the latest edition.
4 As a result the phone could not make or receive calls on the '3' network. But... it can make and receive calls on the 'O2' network. However, '3' is my contract network and so I want to stay with that. Also, I think the companies are running down 2G transmissions ?? so eventually I may have problems with O2 .
FYI it seems the problem may be that the phone is not sending or receiving certain frequencies as otherwise why would it work ok on O2 but not 3??
**********Tried to resolve by:
5 New sim card
6 Factory reset
7 Clear partition
8 Flashing, again. I tried:
a latest XEU
b latest BTU
c previous XEU
d previous BTU
e previous XEU but with the modem file from EE
f previous XEU but with the modem file from 3
g previous XEU again but then did an over the air update to current XEU
Non of them worked.
*****Conclusion
My phone still will not make or receive calls on the 3 network - it won't register on the network (yes I have tried resetting, selecting network etc etc). It sometimes works with text messages though?? And 4G sometimes works. Otherwise the phone works perfectly, just not for phone calls.
Again on the O2 network all seems to work and I can make and receive calls.
So, to for me, it is bricked in that I can't use it as a phone.
I find it completely inexplicable that I can't get it to work on 3 for calls. There doesn't seem any logic to it.
But thanks everyone for all of your kind help. If anyone has any more suggestions I am willing to try them. Especially if they know how to turn on the relevant frequencies on the phone.
Bit of info: Samsung kindly ran a test to check the reception and transmission of signals. But the test wouldn't even start because it couldn't test the first frequency (apparently it should test lots).

RRoyy
Many thanks again for your reply. You've been very kind with your time.
Yes I can flash the current XEU but it still doesn't work. And I flashed the previous XEU and then did an update using over the air from the phone. But still it doesn't work.
Very best wishes
Bob

Weird
I put an EE sim into my phone (the previous owner had bought it unlocked but used it with an EE contract).
Then I put my '3' sim into my phone. And............ I was able to make one!! call.
After that it stopped working.
That was on XEU where I had downloaded the previous version and let it update over the air.
Does this in any way help diagnose the problem??
Thanks again.

Flash that version and update via smart switch please not ota. I've XEU device and I flashed btu many times to my device never had any problem. Than I update my device to TUR to get updates released bu Turkish operators.
There must be something about installization process that's why I'm asking you to update your device over pc via Smart Switch.

Thank you again RRoyy
I shall do as you suggest.
I think you are saying:
1 Flash previous version of XEU???
2 Then update to current version of XEU using 'smart switch'
3 Should I flash with my '3' sim card in the phone. Or not?
Is that correct?
Also, a small point but I didn't know smartswitch could update firmware. I have never used it. But shall give it a try.
If you could please tell me if the above is correct before I do it I would be most grateful. And thank you again for your time.
Side note: Today I tried an EE sim. It does work, but only on 2G. Not on 3G or auto switch. So, it may be the case that the original flashing of BTU that I did first of all somehow made the phone only 2G? Is that possible?
++Update. Smartswitch spent ages trying to update but failed at the last bit. IT downloaded the software but failed on installation. I have no idea why.
Any suggestions??
Best wishes
Bob

Hello again. So I still haven't had any luck.
I flashed the BTU before the current version. But then the smartswitch wouldn't update it to the current version. It claimed it was already current. It wouldn't update over the air either.
I then flashed the XEU before the current version and I DID manage to get smartswitch to update it to the current version. But '3' sim still not working.
It seems that the problem revolves around certain frequencies that do/don't work on my phone. I suppose it could be a hardware issue though that is unlikely seeing as it happened immediately after I flashed the phone for the first time.
This gives rise to two quesions:
1 Does flashing the firmware get rid of EVERYTHING on the phone. Or does it leave residual bits of information that aren't overwritten?
2 Perhaps the problem is the 'CP' software which seems to be the same for all the options I can flash.
3 If I could flash with firmware from another country with a different CP file perhaps that might push the phone into action.
4 Is there a way to check what frequencies my phone can and cannot receive transmit. I don't mean the specifications. I mean the actual received/transmitted frequencies/bands.
Many thanks again.
Finally, apologies for posting this without logging in but there is a problem with trying to login to the forum on this Chromebook. The space for name and password is not visible. Works ok in windows 10 but not on my chromebook.

1) Yes I believe the efs of the phone is not wiped when flashing software. Everything else is wiped.
2) You could try another country rom. Just make sure the model number is the same. Changing the CP could work as CP is the modem file.
