[Q] Problems with Verizone Galaxy S3 as GSM Global

Hello there,
I am trying to get my Verizon Galaxy S3 to work in Germany. I have rooted my phone and flashed JellyBeans vs. 0.1.8.
I followed the steps in this guide:
http://forum.xda-developers.com/showthread.php?t=1809314
When I am in the Mobile networks settings, I have changed the access points name to Vodafone (the carrier I am trying to use ) I have already changed the Network mode with the Phone Info app. After I try to change the access points name, it asks me to select a network operator. My phone then begins searching and it lists Vodafone DE as one of the options to select. When I select that option, my phone tries to register this option, but eventually it says "Unable to Connect, Try again later"
Can anyone offer any advice as to how to get my phone working with Vodafone? I've read and reread the guide I listed above, as well as searched for other threads that talk about issues similar to what I am experiencing, but I haven't had any luck. I would appreciate it so much if anyone has any suggestions!
Thanks!:fingers-crossed:

[Completed] [Q] A T&T Lg G2 &Samsung S5 both unlocked, no Telephone nor text

I have bought two phones from the same person with the same story for both phones; The story goes that ATT could not provide good reception at his home with these phones and replaced them with new ones. He sold me the old ones. Neither are on the blacklist, and now both are unlocked. Neither telephone not texting work on Tmobile, However, both work on Att at Att regional fix it place. T-mobilre states that it is an issue with Att, LG states that the phones are fine.
I recieve these error messages:
LG G2...Upon entering 2945#*800# gets a 5 option menu for sim unlocking, all of which return the message "Your phone is not persaonalized"
.....3845#*800#accesses the hidden menu. yielding: firmware 4.2.2, APN Delete states that there is nothing to delete, RMnet auto connect Mode is Off; RF call info yields calibration status OK; Call Test, Auto call test yields Not implementation: Modem Settings, LTE Band Selection lists Bands 1-5,7,8,17,and 20. All of which when checked result in FAIL.
In Modem Settings, In LTE-A CA setting, There are 3 "buttons" titledCA Enable / SupportedBandO?(it runs off the line) listing all-enable,Pcell B4 Scell B17, and Pcell B2 Scell B17,Pcell B177 Scell B2, and the other two "buttons" CA Disable / Rel. 10, and Rel. 9. For whatever that means.?
I ran a bug report that resulted in a 1,457 page document(5.9mb), not attached, as it is way too big. If you were to run a word search on telephony, it might tell someone more knowledgeable than me what is wrong with this phone. If you need to see it I will post it to box and give you access to it. If there is any more information that is needed, I will gladly provide it.
I've read this forum for about a month on this issue, and am probably stumped because I am beyond my level of understanding here.
Whatever suggestions you have would be appreciated.
PS, the phones work in every other way that we have tried.
Thanks, Woody3

Please Review Att to Tmobile lg g2
Understand that Phone may or may not be unlocked. But you need correct APNs to make Data and MMS Work. You need SIM unlocked to get a Signal with T-Mo Sim. Same with your other phone the S5. Please review SM-G900T on AT&T MMS problem
Please post on the respective threads if you continue to have issues.

Thanks, I tried to set up the APN again, but still get kicked back to the mobile network folder when it tries to connect automatically...I can not connect to the network, it doesn't get that far, it keeps putting me back two folders back.. If this is the wrong thread, Please direct me to the correct one. I read the thread that you referenced above, but my phone won't get that far in the process, and therefore that thread does not go deep enough. Am I missing siomething else?
I will check on the Sim unlocked issue, mine would be locked.
Thanks for your time.

[Completed] [Q] not connecting to rogers LTE - Ulefone be pro android

Have had the phone for a week with no success even with rogers support
Gave me the LTE APN and my phone isn't connecting to LTE network, I added it manually still with no success
Sim card connects to LTE in my old xperia with no issues
Network keeps jumping from 3G and 4G
Don't have any clue on my next step and rogers blaming the hardware as they don't have any other resolution
is 4g the same as LTE and maybe I just don't know..is there anything I can do to test the lte antenna? I would like to rule out the hardware but I don't think its the hardware......
any help would be greatly appreciated

Hi
Thanks for writing to us at XDA Assist. Open your dialer and enter this code:
Code:
*#*#4636#*#*
That will open a menu from which you can select Phone Information, once in the Phone Information screen, scroll down and you'll see a drop-down menu where you can select network types, try selecting "LTE only" to see if you can connect to an LTE network.
Also, what phone are we talking about here?

No response in two days, thread closed.

Seems that you have changed the frequencies of your mobile network connection.
You may try to change it back to the original frequencies ... if you know the original settings.
If not, you may ask your mobile carrier.
For more detailed help, you have to register on xda and search your device's sepecific forum.
I found some threads about the system menu, you have used to change your mobile network frequencies:

No general solution. You have to check for your specific device how to reset the original settings.

[Completed] Help! Tmobile Samsung S7 locked only on 1800 mhz band. Already rooted

Hi everyone.
Last time i was in xda forums was when i try to mod my windows mobile CE 5.0 lol
This is my sad story:
I bought in the US a samsung s7 with T-Mobile SM-G930T, i paid a guy who 'unlocked' it in there. After that i brought it to Colombia, in here i run the T-mobile unlock app which succeded and erased itself after that. Then the cellphone started working with all the mobile companies in my country except for one that operates over 1800 mhz, other companies do work fine. When i insert a simcard of this company it just says that 'Not registered in network' and wont do nothing. I already tried to put the APN settings correctly (Actually it automatically loaded every company settings detected).
After that i tried to root with a modded Odin with a custom ROM and it succeeded and i got the SuperSU application, tho the cellphone its a little laggy now, but neither that way it worked. Anyone knows how where should i start looking?
I went to this company support and they sent me to Samsung support, which redirected me back to this company, lol
Thanks in advance guys

Hi,
It seems your phone is region locked due to which you are locked onto a particular mhz network frequency...
yes the first step would be to try to a custom rom to see if this over rides this situation or you could try below situation below... this is ideally for s6.... or atlast google search...
http://forum.xda-developers.com/verizon-galaxy-s6/general/enabling-using-servicemode-t3109579
Ok, since now we have root, many users wanted to know if they can lock onto certain LTE frequency bands using Samsung's ServiceMode. So here is a quick guide.
ServiceMode is Samsung's proprietary Engineering Mode, built within the TouchWiz framework, readily available on International variants, and some domestic like T-Mobile. It allows us to observe the RF connection, change certain RF related settings, and lock our phones onto specific technologies and frequencies. Sadly, Verizon has been blocking user access to Engineering Mode for years now.
So in order to enable access to ServiceMode on Verizon GS6/Edge you'll need to:
- Download Root Explorer
- Navigate to /efs/carrier/HiddenMenu
- Use TextEdit to open it (not text viewer)
- Change the value to ON (upper case), Save and Exit
- Restart the phone
Once restarted you can dial:
*#0011# to observe the connection
If you want to lock your device onto a specific LTE band (13, 4, 2):
*#27663368378#
- UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
- LTE Band Selection
Here you can force your phone onto a specific Verizon LTE Band (13, 4, 2), or use LTE ALL if you have VoLTE (Advanced Calling) enabled as this will eliminate the need for CDMA radios.
To go back to default, go through the same process but at Band Selection make sure to chose AUTOMATIC.
There are a lot more settings here, you can enable AMR WB on UMTS if you use T-Mobile so you can get HD Voice on their UMTS layer, etc... Carrier Aggregation has already been enabled, so no need to tweak that.
If you aren't sure what certain settings and values correspond to, it's better to avoid tinkering. You're responsible for your own actions.
