I got a Sprint LS990 ZV6 phone from ebay. I decided to use it in T-Mobile, so rooted it. After following so many steps, the phone is not accepting any SIM card when I switch to GSM.
I followed below steps.
- Downgraded phone to ZV4 from ZV6
- Rooted the phone using Stump root
- Changed the carrier options as per http://forum.xda-developers.com/sprint-lg-g3/general/unlock-sim-gsm-how-to-t2853594
- Added APN settings for T-mobile changed network pref
- Inserted my SIM and rebooted the phone.... I shows No SIM card (the SIM is working properly in other phones & I tried couple of SIMs nothing works)
Can anyone please tell me after downgrading & rooting the phone, will it show Active SIM for GSM (i.e. signal bar not with red cross and No SIM icon).
If anyone faced this issue and resolved it, please help me also on this. I have been struggling from more than 2 months to fix it.
Try this http://forum.xda-developers.com/sprint-lg-g3/general/how-to-gsm-unlock-t2961099 I made it and listed people that confirmed it working if you need help pm me or them.
Finally after following below steps it worked
GSM Unlock for Sprint LG G3 (Works for US GSM Carriers & International Carriers)
1. Root the device using StumpRoot - Download here http://forum.xda-developers.com/lg-g...rizon-t2850906
2. Install SuperSU & Root Explorer & 920 Text Editor (or you can use Rom Tool Box for build.prop editing)
3. Copy build.prop from /system/build.prop to /sdcard
4. Open /sdcard/build.prop in 920 Text Editor
5. Edit line 268 and change ro.build.target_operator=SPR to ro.build.target_operator=spr
6. Save the file
7. Go to root explorer and copy build.prop from /sdcard to /system/ - try and delete existing build.prop and then copying the one from /sdcard instead of overwriting the existing file. I've encountered bootloops when overwriting build.prop
8. change permissions on /system/build.prop file you just copied to "rw - r - r". This is very important - when you copy and paste build.prop it loses the correct permissions and incorrect permissions will result in bootloop
9. reboot the device
10. It should now be unlocked. You will be unable to change the Network mode under "Mobile Networks" which will be grayed out so use the app "Network" from the play store to change the modem to "GSM (auto PRL)
11. In a few seconds you should see a signal. If not reboot the device once again and it should work.
12. Download "Tweakker" from the play store to get to APN settings and configure required APN settings for your carrier. After you are done with this step, you should have 3G/HSPA+ or Edge connectivity

Thank you. I was using these steps as well.
Now the next search is using this phone in T-Mobile or at&t for LTE.
Does any one got any spell for this
As far as I know you cannot use LTE due to the face our device does not support it.
This is a status bar enhancement for build 19 & 25 Nougat (stock only) for the A2017U (USA version). Here are the features:
Changed network type icons for 4G LTE, 4G LTE/CDMA, 3G EvDO, and 3G HSPA to be a bit sleeker. EDGE remains as-is.
Removal of NFC icon
Removal of SIM disabled icon (for dual SIM users)
Removal of roaming icon
Removal of carrier label (if non-carrier label ZIP is flashed)
Below are two flashable ZIPs, one with carrier label and one without. Screenshots are below. If you don't wish to flash via recovery and have root, you can just replace your SystemUI_ZTE file with the one in the ZIP files and set CHMOD to 0644.
Here are the links...source file for SystemUI_ZTE.apk is ZTE's stock file...I used APKTool 2.2.2 to decompile/recompile the file after editing. I use Google Drive so it may tell you that "This file type is unsupported" if you're opening these links on your phone. But, if this happens just tap the top three dots at top right and choose "Download."
SystemUI_ZTE mod without carrier label (B19 only)
SystemUI_ZTE mod with carrier label (B19 only)
SystemUI_ZTE mod without carrier label (B25 only)
SystemUI_ZTE mod with carrier label (B25 only)
Enjoy! Please let me know of any problems...and of course, use mod at your own risk though this should flash just fine in TWRP as long as you're using Nougat stock build 19 or 25. Also, please be sure to do a backup of your System (or at least your SystemUI_ZTE.apk file) prior to flashing, just in case.
Finally, if you're a Verizon user and/or just like the Verizon-style icons, I created a thread a while back with this at the following: Verizon SystemUI for A2017U
Is it possible to do this modification on A2017G Nougat B10
.Changed network type icons for 4G LTE, 4G
LTE/CDMA, 3G EvDO, and 3G HSPA to be a bit
sleeker. EDGE remains as-is.
.Removal of SIM disabled icon (for dual SIM users)
.Removal of roaming icon
After a sleepless night, I managed to make a modification myself
I know that the post was a long time ago but maybe someone did it for the G version. Sorry for my English.
Hi I have a question, i've been looking everywhere on the internet but I haven't found anything.
My Network type icon doesn't show up when im using it. I get no 4G/4G-LTE/3G Icon in my status bar.
How can I change/fix this?
Hello, I have not encountered such a problem of the lack of network icons, this modification only replaces the icon. You may need to restore the phone to factory settings.
Sorry for my English.
After over a week of trying, I've come up with a solution to enable WiFi Calling (probably also VoLTE) in Fulmics ROM for LG G6 and probably G5 running any stock based ROM.
THIS GUIDE WILL ONLY WORK IF YOUR DEVICE IS ON THE LIST OF YOUR CARRIER'S VOWIFI/VOLTE SUPPORTED DEVICES AND THE SERVICE IS ENABLED THROUGH AN OTA UPDATE FOR YOUR STOCK, BRANDED ROM PROVIDED BY YOUR CARRIER!
I don't believe in magic, you shouldn't either so don't think this guide will make VoWiFi/VoLTE work on your device regardless of your carrier's support for your phone model.
Also, if your provider offers VoLTE/VoWiFi through an external app available in Play Store, don't bother reading any further.
General idea described in this guide is to tweak your rom in a way that it is recognized by your carrier as their own VoLTE/VoWiFi enabled build that has a "green light" for IMS and Xcap apns registration in your provider's VoLTE/VoWiFi service. During my attempts you make the service work on my G6 running V10t based Fulmics ROM i discovered that adding IMS and Xcap apns plus getting all the IMS and GPRI VoLTE/WoWiFi hidden menu settings right is not enough. I had everything set up right and still couldn't make a WiFi call. Then it occured to me that maybe i can't make it work because Fulmics ROM is based v10t, and my provider's VoLTE/WoWiFi enabled rom is the v10h? So i tweaked Fulmics 1.6, then 2.0 so it masks itself in front of my provider as v10h while in fact it still is v10t Fulmics ROM 2.0. And guess what... IT WORKED!!! My Carrier's IMS and Xcap apns, manually added by me to the default open-eu apn list storred in /system/etc/apns-conf.xml, got registered in the service activating WiFi Calling on my device.
How to do it step-by-step guide below
1. PREREQUISITES:
- /OP/[YOUR CARRIER'S CUST FOLDER IN XXX_XX NAME FORMAT] in your main dir /root. If you only have OPEN_EU in your /OP you must get your carrier's specific cust folder or install Fulmics over your carrier's VoLTE/VoWiFi enabled rom then the cust folder you need will appear in /OP
- build.prop file from your Carrier's VoLTE/VoWiFi enabled rom for your LG model (make sure following line is in the file: ro.lge.cupp_capss.rootdir=/OP
- /OP dicectory in your device main root directory with your carrier's VoLTE/VoWiFi enabled ROM's subfolder (XXX_XX format). OPEN-EU or
GLOBAL-COM are not the ones .
- files from your carrier's rom: /root/data/ipsec/wo_apn.conf, /root/data/ipsec/wo/apn_xcap.conf
(You can try without those 2 files if you can't get them).
2. TO DO:
!!! AT SOME POINT OF CHANGING STUFF LISTED BELOW YOU WILL GET ALOT OF FC OF VARIOUS APPS. DON'T PANIC, JIST REBOOT YOUR DEVICE AND CARRY ON WITH CHANGES !!!
- in /OP directory delete folder _COMMON if you have one
- in /OP directory create a new directory called SUPERSET and set perms to 755
- copy all content from your carrier specific folder in /OP to SUPERSET. You can also just try renaming cour carrier's folder to SUPERSET instead of creating new filder and copying stuff to it.
- edit cust_group_mapping.cfg in /OP and change whatever you have after = to GLOBAL-COM
- open cust_path_mapping.cfg in /OP and make sure you have 999999,99=/OP/SUPERSET there on the list of providers
-edit official_op_resize.cfg and add SUPERSET_SIZE=[copy size value of your carrier's folder which should also be listed in the file]
-in /OP/SUPERSET (with your carrier's files coppied) edit cust.prop and in second line in the file change whatever you have after = to SUPERSET
- edit your rom current build.prop file and copy all additional stuff (in my case it was all the Fulmics ROM part of build.prop so from #Software Version down) to the build.prop acquired from your carrier's VoLTE/VoWiFi enabled rom. Add the coppied stuff at the bottom of the list.
- add following lines at the end of stuff coppied to your carrier's build.prop from step above:
persist.sys.cust.lte_config=true
persist.lg.data.iwlan.enable=true
# Debug Options
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
# Radio Options
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
# applying GPRI auto-commit
ro.lge.radio_gpri=1
ro.lge.amrwb_gpri=1
wlan.lge.softap5g=false
# 2015-10-12 [email protected] LGP_DATA_IWLAN [START]
persist.lg.data.iwlan=1
persist.lg.data.iwlan.ipsec.ap=1
# 2015-10-12 [email protected] LGP_DATA_IWLAN [END]
Save the build.prop file and place it over your current system default build.prop. set perms to 644
- open your device's hidden menu, go to
Field Test->GPRI VoLTE/VoWiFi->UX and tick 3rd, 4th, 5th, 6th and 9th for WoWiFi only, all except 8th for VoLTE/VoWiFi and 1st and 2nd for VoLTE only.
- go to your apns in network settings and make sure you have all the apns needed (in my case the are: internet, mms, ims and xcap). If you don't have them, try sending settings request message to your carrier's apn service center, if that doesn't help, add the apns manually (you must find your carrier's specific manual settings on the internet). You can also edit /system/etc/apns-conf.xml file and add missing apns manually to the list in above file. To do that you must find your carrier's apns on the list first, (list order by MCC-MNC code) under your carrier's last apn enter your VoLTE/VoWiFi apns in the same way the other apns in the file are typed.
-save apns-conf.xml, go back to apn list in network settings, tap overview->restore defaults and the missing apns you added to your xml file should appear on the list in network settings.
-make sure you have all permissions right of the created/coppied/edited files and reboot your device.
When your phone boots back up to Fulmics you should have your carrier's boot animation instead of default LG one, then you should see initial boot screen with "android is setting up" for a couple of seconds, then your homescreen. When configuring of your sustem is done, open quick settings and your VoLTE and WiFi Calling tiles should appear there. Turn on what you want and test if it's working. Remember, with VoWiFi you must have both WiFi and WiFi calling ON. The easiest way to tell if WiFi Calling is active is the presence of a headphone with little WiFi icon on the status bar and other places in your dialer etc. To test, turn on airplane mode, wait till WiFi gets turned off, turn it back on in airplane mode, wait for WiFi calling icon on status bar and try to make a call with airplane mode on .
REMEMBER! This guide will will only work if your carrier verifies WiFi enabled devices by 3 conditions: 1. Device supported, 2. Apns present, 3. ROM build match (info from build.prop).
I might have forgotten about something (or not ) but will edit if or when questions start to be asked

@mrbeem tried flashing back the kdz trough lgup but in OP i found only three folders: _COMMON, lost+found and OPEN_EU, plus a lot of individual files.
Any clues? Can you specify what files the operator folder should contain? Thanks in advance!

What rom did you flash in LG UP? Was it your provider's stock ROM with WiFi Calling service enabled or was it Open EU rom? OP should contain your carrier's config files of you flash your provider's ROM. The files should be in a separate folder with your Carrier's name (for example, Vodafone Italy should have a folder in /OP named VDF_IT etc.). Carrier specific folder should contain subfolders called: config, overlay, apps, media, poweron, poweroff. Most impostant are: config and overlay. Also in /OP there should be 3 files apart from the subfolders: cust.prop, official_op_resize.cfg and except_buyercode.cfg
Pics of content of cust.prop and official_op_resize.cfg from my carrier's folder (P4P_PL)

The OPEN EU that Bridge downloads when my phone is connected, and is the same one which is referred as "Vodafone Italy" on LG Firmware.
In /OP i have these files: op_list, official_op_resize, custom_path_mapping, custo_group_mapping, client_id, buerycode, strangely are almost the same found on fulmics.
In Open_EU i've overlay and config folders, and these files: official_op_resize.cfg, except_buyercode.cfg and cust.prop.
The strange thing is that the vodafone brand remains also with the fulmics, in fact at everye clean installation i found vodafone apps and vodafone configuration before restore my lgbackup, what a mess lol

Ok so you have the everything. Just delete _COMMON filder, create SUPERSET and copy all from OPEN_EU to SUPERSET. Basicly follow the steps. Build.prop is most important part. Plus check if you have all apns needed for WiFi Calling, if not, add manually as described. It is a mess, but the key is to put that mess in an order that enables WiFi Calling. Carrier's boot animation on fulmics is a very good indication that you're on the right path to make it work. Just a small tip... Maybe start from the UI part to enable the ability to turn VoWiFi on/off and then the rest. This way you'll be able to see if or when your service becomes active. So.....
1. Copy this to your carrier's build.prop after you've coppied the Fulmics part:
persist.sys.cust.lte_config=true
persist.lg.data.iwlan.enable=true
# Debug Options
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
# Radio Options
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
# applying GPRI auto-commit
ro.lge.radio_gpri=1
ro.lge.amrwb_gpri=1
wlan.lge.softap5g=false
# 2015-10-12 [email protected] LGP_DATA_IWLAN [START]
persist.lg.data.iwlan=1
persist.lg.data.iwlan.ipsec.ap=1
# 2015-10-12 [email protected] LGP_DATA_IWLAN [END]
2. Replace stock fulmics build.prop with the one from your carrier's rom with Fulmics part and above lines added. Check permissions and reboot.
3. Ho to hidden menu Field Test->GPRI VoLTE/VoWiFi->UX and tick all ON apart from 1, 2 and 7. Go back to main hidden menu screen and to to Service Menu->WoWiFi and change value to 1.
4 reboot and check if you have WiFi Calling QS Tile added and WiFi Calling settings enabled in call settings.

What apns do you currently have on the list?
Can you check what is your sim MCC-MNC CODE? Go to hidden menu, field test->SIM Info and check values under MCC and MNC. Is it 222 and 10??

Ok. I found apns for you. There are 3 more to add. Give me an hour or so and i will make apns-conf.xml for you. Make backup of your apn-conf.xml file and when i send you new one you will just replace your file with mine, go to settings wi
th apn list (one from screen above) and hit restore defaults .
One more thing... Can you tap on the top apn from the list to open it? Then scroll down to see apn type , take a screenshot and post it here

Im using latest fulmics. And also i'm trying to create manually ELE_EE configuration. I have all information that i need from operator but not sure is it possible. Anyway i got this phone from LG baltics to do it.
Good news for anyone having the Wing fall Back to 3G when making a call. You can activate VoLTE using a mix of the two following guides:
Guide:-How To Activate VoLTE,ViLTE,VoWIFI&ViWIFI LG Devices-LG Velvet 5G
Hi Guys Am Baljeet From India There Is A Path To Force Enable VoLTE On The"LG Velvet 5G LM-G900" Specifically Your Version Which Is The "LM-G900". By Default This Feature Is Disabled On This Model. Follow These Steps Given Below: A). Go To The...
forum.xda-developers.com
and
Lg g8x,g8,v60 Volte enable for all carriers, unlisted countries also
I will try to keep this post as small as possible. This will enable Volte for Phone ranging from Lg g8x, g8 and V60 without root or modifying the system files. Many have posted ways to get it, Iam only trying to help out the small bits missing...
forum.xda-developers.com
To make it as short as possible:
1) Create an empty directory named "enable_ue" in the root of the phone's main storage, using you prefered file explorer (like for exemple Cx Explorer or ).
2) From the LG Phone dialpad and with your SIM card inserted, type #*462633*#100# (for european LG Wing - LM-F100EMW) to get into the Hidden Menu. From there enter Field Test, then Universal Enabler -> Create New Config. Click on the four last check boxes VoLTE, ViLTE, VoWIFI and ViWIFI to enable these options. You won't be able to enter this setting if you haven't created the empty directory under point 1).
Go back to Field Test and enter Modem Setting to enable 5G if you haven't already -> RAT Selection -> SIM 1 Mode - > select GSM/WCDMA/LTE/5G or whatever you need + 5G. Go back and do the same with SIM 2 after, if you use it. Network mode in the network settings will then not show "5G prefered", but a number, like "26" in my case.
3) Go back to Field Test menu and enter IMS Stting. If you have Slot - 0 : OPEN / EU and Slot - 1 : OPEN / EU (or something else on each side of the / ), then you did everything right to this point. Exit the Hidden Menu and get your SIM out of the phone.
4) Enter th Hidden Menu again without the SIM inserted. Go back to IMS Setting and click on Slot - 0.
Under Subscriber enable IMS,ISIM & USIM.
Under Xcap\Ut. -> General, enable UT & USSD Over IMS
Under ETC, enable Check IMS Registration, Use rule-ID from responsem& Query on bootup
Under GPRI VoLTE/VoWIFi, enable VoLTE, ViLTE, VoWIFI & VIWIFI
Under Test, Preference Operator can be set as OPEN (what I did), or your carrier short name, or your County. Apparently does not make difference for some operator but some do require it to same name as theirs.
Preference Country this is important as this decides if VoLTE gets enabled, Find your country short code example USA is US , India is IN. Europe is EU. Find and try different short codes, I put EU.
Enable Support Volte AT command, VoNR, UAC Enabled & VoLTE Setting Enabled
You can now exit the Hidden Menu & insert your SIM back in. If everything went well, you should see the VoLTE icon showing up on the left of the network in the task bar, on the (my) Wing it's a small lifted phone headset with wave coming out of it. If you don't have it, check under the phone network settings - Mobile networks, if you got the VoLTE option and if it's activated. You might have to repeat some of the steps above with the SIM card inserted (as I had to) to make it work. Don't forget to check the settings for both SIMs if you use two. Not sure if all setting are kept if you reboot or reset the phone. You might have to repeat the preocess or part of it on each reboot, as for enabeling the 5G option.
Was tested on Android 12, as my phone didn't get Android 13 yet. But it's also working on my Velvet 5G that is on A13.
Many thanks to Baljeet Khairwal and johndaniel for their guides + all other persons who helped in the two threads.
