[Q] No SIM card - After rooting LG G3 and changing to GSM, it is not detecting SIM - Sprint LG G3

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.

I got one of these xt1528 phones but im on ATT can this be done? I heard it can somewhere in settings and Network app and change too LTE/GSM PRL instead of LTE/CDMA. Also if im able to change my apn to ATT would i also be able to rom and root or does that involve unlocked bootloader?
1. No, you cannot perm root
2. No, there's no BL unlock method

Stupid question, but to clarify, the Verizon model will NOT work on ATT? Thanks!

There is temp root via Kingroot for the Verizon model, but /system remains read-only and you can't flash a custom recovery.
You don't need to root to enable GSM.

The Verizon will indeed work on AT&T, but it's lacking AT&T's main LTE Band 17. Has 2G EDGE on 850MHz & 1900MHz, 3G HSPA+ on 850MHz & 1900MHz, and LTE on bands 2 and 4. You'll need to follow this guide to enable GSM compatibility: http://forum.xda-developers.com/moto-e-2015/general/how-to-verizon-moto-e-2015-gsm-network-t3098953

I'm missing something then. I stuck my Straight Talk sim in and it says "not a verizon sim". I've entered the APN settings with no results. I must be missing something.

Did you follow the linked guide to enable GSM?
You'll get a "Not A Verizon SIM" message every time you reboot. It's part of the Verizon ROM.
To disable it, disable com.motorola.setupwizard.
If you also disable vzwAPNpermissions.apk and vzwAPNservice.apk, you'll only have to do the linked instructions once, instead of each time you swap SIMs.

Going by what was said in this post, the debloater package that is floating around XDA Dev: http://forum.xda-developers.com/showpost.php?p=64058197&postcount=739
I'm assuming they're referring to http://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294
Can probably do it manually via ADB but I don't know what the package names for vzwAPNpermissions.apk and vzwAPNservice.apk are.
The command to use is probably along the lines of:
adb shell pm disable com.package.name.com

I just tested this, and this SIM swap worked without adb !!! Awesome !!! It's not that cumbersome either, just follow these simple steps.
Now, is it really necessary to turn on the radio in Network app first ? Also, could I just turn off Airplane mode, and then use Network app to change the network type ? Or will it run something that would screw up things such that I have to use adb ?

[GUIDE] H870 WiFi Calling enable on Stock based ROMS (Fulmics, etc.)

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

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

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.

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

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

PM me with your email address and i will send you edited apns-conf.xml. replace your /system/etc/apns-conf.xml with the one i will send you, go to apn settings tap 3dots at the upper right corner and hit restore defaults and updated apns should come up. Don't forget to tap the empty circle on the right by your internet apn to set the top one as default. I've seen on your screenshot the circle is empty and it shouldn't be

Question - How to enable LTE icon in the status bar (if you're in the US)?

I have been trying to find a way of having LTE display as my network connection instead of 4g+/4g (I know that there's no technical difference, but aesthetically it does make a difference and it's easier to see when you're not on an LTE network).
The closest that I have found to making this happen is the following thread here on XDA: [Guide] Enable LTE Icon on Unrooted Mate 9
I already had a call with AT&T to verify that I am connecting to their LTE network with my device so I know that from a technical backend perspective - I'm good to go.
I was able to obtain the list of current MCC/MNC codes currently configured for my phone using the 'get system hw_show_lte' ADB command. However I'm a bit confused as to how I am supposed to add the MNC/MCC values for my carrier (I'm on AT&T). the MCC code is 310, but there are more than one MNC code (according to this site here: http://www.mcc-mnc.com/)
I don't want to mess anything up as I clearly don't know what I'm doing. Is there a magisk module that can make this change (I searched for LTE and only came up with the VoEnabler module)?
Is there a system file that can be modified via a text editor (so that I can make a backup before making any changes)?
Thanks for the help/guidance in advanced.
Thanks for the link.
I tried the command adb shell settings get system hw_show_lte and I got "null"
Then I used the command adb shell settings put system hw_show_lte "310" and it is showing me the LTE icon with T-Mobile.
Maybe after an OTA I will lose the icon, but at least it is really easy to change it again.

Definitive APN editing guide - Useful for CDMA MVNO users

I spent hours trying to get my APN editing when I did a factory reset on my Nexus 6p. Android 8.1 made editing APNs a royal pain if you are using a CDMA carrier. There are lots of threads spread around on getting Total Wireless, Tracfone, and other carriers working form MMS and internet. A lot of the solutions I found worked most of the way but I needed tethering and finally rooted to be able to edit and get tethering.
The options I have found are
Root your phone and do some SU commands
Pop an alternate carrier sim in and edit the apn (I have not been able to fully test as I don't have an alternate sim)
Use adb to open the apn add dialog while the sim is ejected (result does not allow tethering but local data works)
1) Have a rooted phone. Place phone in airplane mode. Enter the commands shown in <brackets> (don't include the <> symbols). Open a command prompt and enter <adb shell>. Get a su prompt by entering <su>. Modify the verizon apn to point to the correct apn server <content update --uri content://telephony/carriers --bind apn:s:"TRACFONE.VZWENTP" mmsc:s"http://mms.vtext.com/servelets/mms" --where "name='Verizon'"> Your data and mms should start working and tether should work as well.
2) Use a T-mobile, AT&T or similar sim and enter the total wireless (or MVNO settings of your choice) APN settings. Remove alternate sim and insert MVNO sim. Go to APN settings and select the new APN.
3) Have your screen unlocked on your phone. At a shell prompt enter <adb shell am start -a android.intent.action.INSERT content://telephony/carriers --ei simId -1> Enter the MVNO APN settings found on google and save. It may give an error if you enter DUN profile. I was not able to get tether to work this way so I used method 1.
Feel free to add other methods that work. Make note of the software version you are utilizing.

Well I have to eat crow. I thought this was working great but I can either have tether or mms but not both. Method 3 allows MMS to work but not tether. Method 1 allows tether and data to work but not MMS!!!!!
NO ROOT NEEDED --- For anyone still having this issue, I have an LG G7 with a Sprint locked APN and I tried every single method I could find online but this is the only thing that worked for me and it worked perfectly:

How to enable Volte

I see lots of discussion on rooting, unlocking bootloader, etc. But I am wondering if there is guide describing how to enable volte for tmobile? That is all I am looking for and I am really not savy/technical when it comes to phones. I have the dual SIM 850 emw and I really dont want to lose use of the phone when tmobile dumps 3g next month. Thank you
Found this. Sort of cryptic.
I used the dailer code on my Samsung to verify VoLTE was enabled, otherwise it doesn't show the setting or that it's even HD.
Apparently AT&T supports this device if your carrier drops the ball. Verify this though...

Thanks for pointing me in the right direction! I now have VoLTE and Wifi Calling working on my LMG820QM (on T-mobile).
I have the BPT variant of the LMG820QM, for which VoLTE and Wifi Calling does not work. After bootloader unlocking and rooting, I tried the above VolteFix-v1 but wanted Wifi Calling. Forcing the option to appear via a profile in Universal Enabler in the hidden menu* did not work and instead caused LG IMS to continuously crash.
*For those interested in the hidden menu, first create an empty folder named "enable_ue" in internal storage. Then go to the dialer and type *#546368#*820#. In Field Test > Universal Enabler you can "Create New Config" and manually enable VoLTE, ViLTE, VoWIFI, and ViWIFI. However, even though these options became enabled in *#*#4636#*#* they didn't seem to actually work.
Next, I tried to crossflash partitions from the US Open kdz but was unable to due to a size mismatch of the OP partition (among other problems).
Finally, since I had already extracted the OP partition from the US Open kdz (G820QM20f_00_NAO_US_OP_0402.kdz), I extracted files that looked relevant and copied them over using a root browser into /product/OP. After setting permissions and restarting, I now have working VoLTE and Wifi Calling!
The files are cust.prop [update: apparently not needed; my existing one worked just fine], all the files in config, and a few folders in priv-app [update: these are the apps for Wifi Calling!] not present in my phone's kdz (not sure which ones if any of these apks are actually needed but since it works I'm not going to experiment more). See attached for details.
Note: Since these files are from the US Open kdz, it will likely only work for US carriers. But the process can be repeated for other regions with the right kdz.
UPDATE: Replaced the attachment, had the wrong files in Config.
** Noticed that upon factory resetting the wrong default APNs are inserted. Had to factory reset on original files, have APNs setup correctly, then copy the attached files (did not copy over cust.prop this time and still worked).

Hello jdapp,
I was able to get VoLTE AND VoWIFI on Mint (T-mobile) with these instructions. I also posted what I did on Post 50. The files work for firmware 20 but if you need the ones for firmware 30 let me know.
Awesome thanks. Yes if I could get the firmware 30 files that would be great.

No problem, let me know how it goes.
So I have tried to do the bootloader unlock and flash but every time I get a Download fail: Sahara Fail: Q SaharaServer Fail: Process fail?
Any thoughts?
