Hey guys, heres my problem.. I have the s7 edge canadian (G935W8), and i flashed "[8/13 ERv13.6] TEKXnesis ULTRA HYBRID S7E-N7 935F/FD/W8 930F/FD/W8 UNIVERSAL-TEKHDway" It booted up fine but now i have no mobile network, even my imei wont show up, and it wont let me save apn settings for telus.. So i reverted back to my backup and same issue there, No mobile network, even in settings "mobile networks is GONE! so i tried reflashing TEKXnesis rom again, still no mobile network, i then tried King rom, same issue no mobile network... my phone is carrier locked to Telus, would that cause it to act up like that
I just flashed g930v to g930u. I thought I was just unlocking more bands so I can bring my phone to Europe for an upcoming location, but it seems like I lost mobile connection. I have the LTE symbol and i do get data, but my mobile connection is not working. No one can call me. I'm currently on boom wireless mvno (verizon service). Does g930u not support verizon?
You might need the apn settings for your carrier
Which firmware are you on?

I added my carrier's APN settings in "access point names". I am unable to add anything custom in "network operators" it all is selected automatically.
I had the same issue. It seems to be the boom mobile sim card issue. Somehow the sim card is auto configured to let 930U think it is a gsm network, so the phone only has LTE/GSM mode. If you check your network mode, you wouldn't see global or CDMA mode, which verizon uses. There is no issue for verizon on 930U firmware. I had to switch back to 930V firmware.

Same issue, I am needing g930u so I can have some bands unlocked for a trip to china but I can't get Boom Mobile to get any data connection. I am having to go back to g930v
Anyone have any solutions?
Hi guys,
Was able to get a LS997 in Canada. Carrier used is Fido.
Bootloader was unlocked using Dirty Santa.
When using stock based (sprint) rom, I always get an invalid sim error. This causes the phone/cell data not to work.
When using a lineage based rom, sim works perfectly and I get LTE data.
Is this behaviour normal?
Is there a way to make a non-sprint sim work on a stock rom?
Thanks
Update: Tried the WETA US996 rom on the device. Sim is recognized (since its the unlocked version), but LTE only works if I go in Network Mode, disable Global , enable LTE/GSM/UMTS, then set submode to "GSM/GPRS/EDGE only" or "UMTS/HSPA/HSPA+ Only" , then set it to "LTE/LEgacy 3GPP Multi".
This is a PITA since every time the connection is lost, these steps have to be repeated to get LTE data.
Any suggestion would be greatly appreciated.
I am running stock based rom to get the camera app and use the top screen.
Thanks
You have tried root, install twrp and flash file modem

TWRP is already installed and the roms used are rooted. I looked but am unable to find radios/modem for the ls997.
If running AOSP based roms I have no problems getting LTE to work.
Aren't the radio/modem separate from the roms themselves, or are they included with could be the reason it glitches like that?
the phone itself is not carrier unlocked thats why you get invalid sim. when you use lineage roms they dont check if phone is carrier unlocked

Looking at the LTE specs for both phones:
LS997 : LTE band 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 12(700), 25(1900), 26(850), 41(2500)
US996: LTE band 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 12(700), 13(700), 17(700), 20(800), 25(1900)
Source: http://www.gsmarena.com/lg_v20-8238.php
Fido requires 700 MHz on Band 17, 1700/2100 MHz on Band 4, 2600 MHz on Band 7
Source: http://www.fido.ca/consumer/content/configure-unlocked-device-guide
Bands 4 and 7 are a perfect match, and band 17(700) is a subset of band 12(700), so the LS997 should be 100% compatible.

Would you happen to know which modifications I would have to bring to make it so that I can get LTE working out of the box like Lineage for 997 on a 996 unlocked based rom?
Thanks

You would have to use a us996 unlocked ROM with proper apns for your carrier in the apns list. The file is /system/etc/apns-conf.XML I believe

Edited my post above.
APN is properly set automatically on phone. As stated in the first (ERROR: second!) post, I can get LTE working, but need to set GSM/UMTS first then switch to LTE manually, and once the connection is dropped, this procedure has to be done again.
looked at the APN settings, they are the same as described by carrier.....anyone has an idea?

like me2151 said, flash the us996 based rom. Its the unlocked version that will allow sim cards from other carriers to be used.
The ls997 roms are cdma based roms that dont use the sim card for anything but lte and is a locked slot unless device is uicc unlocked by the carrier.
There isnt a method currently to uicc unlock this device without the carrier sending the code to the device.

Hello,
I am currently on WETA US996, but as described in the second post, I cannot get LTE to work without disabling it first, switching to GSM/UMTS, then activating LTE.
Once I switch over to Wifi for a period of time, then switch back to cellular data (example: leaving the house), I lose all data and have to disable LTE again, enable GSM/UMTS, then reactivate LTE to get LTE data.

have you tried a dif option such as global? or WGSM Etc? You may need to select a dif option.
@ME2515 also gave the idea to edit your apns master file in system, so its always holding the apns for your carrier, in theory it would force the device to keep the settings as they become the "default" all the time, vs the devices default auto setting for example.

Hello,
As explained in previous posts, the APNs are properly configured as per Fido settings automatically on the device. I triple checked to make sure all entries were correct.
LTE does work, but only going through the following steps: Go in Network Mode, disable Global , enable LTE/GSM/UMTS, then set submode to "GSM/GPRS/EDGE only" or "UMTS/HSPA/HSPA+ Only" , wait for a data connection, then change it to "LTE/LEgacy 3GPP Multi". Only then will LTE work, and once I switch to wifi, it won't get any LTE data when I disconnect from Wifi unless I go through that procedure again.
Am I really the only one with this problem?
Triple checked APN, it is correct. It's fetched autmatically from Fido when I connect to the network. Still no LTE unless I do the procedure above.
Reply in case someone encounters this issue. The APN setting for LTE was the culprit. I setup the APN as it it weren't an LTE device following the fido directives (using Fido-core-appl1.apn instead of LTEMOBILE.APN) and now get LTE connection when network is set to global.

when installing wetarom to your LS997, what did you select as your device model in the installer? Unlocked US996 or Verizon VS995

ouch...that was long ago. I do not remember. I bought an unlocked US996 afterwards and sold the 997. Now with an S9+, which again gives problems..lol
I have several issues with my US996 on Verizon, running LineageOS 14.1. (I'm not asking in the LOS threads because I figure more people here know the details of this device)
The main problem is I can't get SMS to work unless I set the preferred network type to CDMA or CDMA/EVDO only. I have been using the "VZWINTERNET" APN.
Any time I set an option that includes LTE (including the "Global" setting), SMS/MMS stops working.
Also, the signal indicator works strangely, oftentimes when I have strong signal the signal indicator shows 0 bars.
Lastly, many of the fields in Settings/phone info/SIM Status are blank, eg phone number, signal strength and service state. (Perhaps this is a CDMA/Verizon idiosyncracy since the SIM is not the primary auth to the legacy CDMA network?)
Do I need to flash the VS995 radio to this device to address these things? Is that even feasible? What about what Verizon calls "Advanced Calling" options? Ideally I would love to have VoLTE and WiFi calling as well.
Thanks.

If youre device is abr0 you can use the patched dll version of lg up. https://forum.xda-developers.com/attachment.php?attachmentid=4233875&d=1502007613 to flash vs955 firmware. I have found that the this version VS9951BA01 is the one has fastboot mode and can get to recovery if you want to use dirty santa on it. or if you get to the you have 9 attempts of 10 to enter the passcode. you will then need to factor reset to get the data formated. But this link has the full instructions. https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222

Thanks for that tip, I will read up on it a bit later.
The main reason I got a US996 rather than a VS995 is the lack of an officially unlockable bootloader on the VZW variant and having to use an exploit to unlock/root it which only works on old firmware leading me into a potential trap if the device ends up in a state I can't either unlock/root or return to stock from.
I already unlocked the US996 bootloader - will that get reset if I flash a stock kdz onto it?
I tried using LGup shortly after I got the phone but I was having problems getting it to work on my Win7 workstation, perhaps I had the wrong version..
