hi, can some one help me, for some reason i dont have gsm option in settings
[Sprint LG G3] nemanja1:
Why do you need gsm option in settings?
[Sprint LG G3] Castle2k:
Try this in your dialer: *#*#4636#*#*

Then choose Phone Information and select network that u want.

i need gsm option to switch to gsm because the phone is set to cdma, but i think i know my mystake mine is ls 885, will this work with ls 885?

Lg g3 ls990 Sprint unlocked: use correct permissions!

Hey guys! I finally unlocked my LG G3 LS990 Sprint to work on GSM/HSPA for AT&T. I started with copying those two files into system/carrier/apps per Assamat's instructions. But I didn't know to set the file permissions properly! Many aggravating hours followed. Note.db must be set to rw-rw---. Note.db-Journal must be set to

rw------. Once I did this and rebooted my phone with my ATT sim card in, I no longer got "invalid card". It picked up the signal and is working fine. The network is set to GSM/UDMA.

Thanks to sinisin for the pic that shows the correct permissions. Just found I have 9 more posts to go before I can post pics. But there go!:D
[Sprint LG G3] iBowToAndroid:
No, it won't work with that phone

Next time, save those aggravating hours and make note of what the permissons are for the original files before you replace them :)
[Sprint LG G3] charonjr:
I had followed the original instructions of using rw-rw-- on both files, which yielded the "invalid card". Another poster pic'd the correct permissions, after which it worked. LOL! It is worth the aggravation to pick up knowledge, though. And you are right, I should have noted the original permissions of the original files, rather than being such a noob that I followed the instructions blindly for a first time. :silly:
[Sprint LG G3] locster420:
I have a Samsung galaxy s4 Verizon sch i5451 around that number. Lol. Anyway its 5..0.1 and I can't root it for the life of me. Any help is great. I'm new to this thread. Ki Groot Odin and all others just won't work. Pls have help. Thx
[Sprint LG G3] charonjr:
I have been reading that the official OTA (over the air) updates could do prevent rooting. You probably have to install KitKat first, root it, then use Prime5 for your upgrade to Lollipop. That worked well for me. Just make sure to look up the Android that works for your Samsung. Someone said that Samsung makes it difficult to do. But I think they were referring to getting the original Samsung OS for putting the phone back to its original condition. My apologies, I have read so much that it's mixed up in my head.
[Sprint LG G3] Android.Dev99:
Will this work on Cyanogenmod ls990 ? Please help because I don't now if I will find the same carrier folder or not. However it worked fine for me on Kitkat, I'm in Morocco.
[Sprint LG G3] Bvkbads:
what do you mean by /carrier/apps and how do you search in shortcut master
[Sprint LG G3] charonjr:
he means system/carrier/apps.:)
[Sprint LG G3] Bvkbads:
Where is system/carrier/apps?
[Sprint LG G3] charonjr:
Do you have Root Explorer or ES File Manager? To use these, your phone has to be rooted first. But, you open Root Explorer and you will find yourself already at the root level. Click on Mount R/W. The third folder down is Carrier. Click on it and you will see a folder within called Apps. Open that and you will the node.db and node.db journal files. These are the ones you back up (rename to node.db.bak and node.db journal.bak), then copy in the ones posted at the beginning of this thread. Make sure you put the permissions like this: node.db rw-rw-- and node.db journal rw----.

Turn off your phone, put in the SIM you want to use and Reboot your phone. Then go to settings, tethering and networks, mobile networks, network mode. Here you choose the network you want to be on. Since I wanted to use ATT, a gsm network, I set mine on gsm/wcdma/lte auto. The other options are gsm/wcdma auto, wcdma only and gsm only. My phone picked it all up automatically from there. Note that I am using Primegsm 5 v5 from ki11aprime.
[Sprint LG G3] Tuan2sky:
i have tried this way again and again. But unfortunally, ít's not working perfectly. GSM icon is showed in status bar. i can using mobile data, but...so sad, it's speed very slow, and i have cause to belive that it's not 3G mobile internet. With this kind of mobile data, we can't do most of things.

ANyone have another solution, please??
[Sprint LG G3] AlexMas0n:
Question

I won a free Sprint G3 in a contest, and need it working with AT&T. All I have to do is root the phone, and copy those two files over, and change the permissions, and that's it? How do I change the permissions?
[Sprint LG G3] Gustavo linux:
You use it to telcel? i only get gsm speed and is too slow
[Sprint LG G3] Cody92:
I just got it working on 5.0.1 (LS990ZVA), but it still says it Sprint. Calls and text go through, but I'm totally stuck in a loop. When I want to end a call there is like a minute delay to end it because it does some weird condition call forwarding thing. I tried disable it but apparently it only works when you call through Sprint to disable it, even looked for it using shortcut master. They all tried calling through sprint. I'll be sure to update if I get it figured out though. Aside from the issue it is working with data even on Cricket in the US though.
[Sprint LG G3] kcking26:
Would a factory reset delete the unlock? If so is there another way to delete data if you want to sell the phone?
[Sprint LG G3] 1619415:
You can just wipe the data and cache partitions, then all of your stuff is gone but the unlock is still there.

Thanks for responding! I messed up real bad but somehow could figure out a way to get back to original stock settings :). I am back to a point where the phone is rooted and i have done couple of things suggested on this post but none of them helps. My phone still cant read any GSM sim. I want to try my hands with editing build.prop file. Can you please elaborate on fixing permissions? Is there a parameter in the file that will do this? :confused:
[Sprint LG G3] 12manytimes:
1st off which software version is your device on? 2nd is the IMEI clean?

If on kitkat and imei is clean then steps are very easy...all u need to do is a root Explorer and navigate to your build.prop...before u do anything take a look at stock permissions because when u are done u will need to change the modified build.propz permission to match the original....next make a copy of the build.prop..push it to the SDCard..connect to Pc, pull copy off..with notepad++ change SPR to spr..place back on device and replace original on phone(make sure u have correct permissions) then go to settings and make sure roaming guards are disabled and network mode is changed to GSM/UMTS..then reboot and u should have network[emoji1]

[Sprint LG G3] EltonGovada:
Thanks a lot for the detailed procedure. I followed the guide and did exactly what it told me to do. After rooting and accessing build.prop, I changed the operator to "spr" instead of "SPR." I also changed the permissions and deleted the previous build.prop before moving the new. After doing a reboot, i didn't go into a boot loop, but instead my wifi stopped working and i kept getting a popup every 2 seconds that says "com.android.settings stopped working." Any help in resolving this would be very nice.

[Sprint LG G3] rishidhar:
This is working for me but I did something different

I'm not sure why you had to change it to "OPEN"

I simply changed ro.build.target_operator to spr (not "SPR") and that worked for me. Unlocked on T-Mobile.

Once you change it from SPR to spr you lose certain settings menu options like "Roaming" and "Mobile Networks"

Use "Network" app and "Tweakker" from the play store to change from CDMA to GSM / WDCMA mode and the Tweakker app to change APN's.

Doesn't show H or H+, just shows GSM.

---------- Post added at 08:53 PM ---------- Previous post was at 08:53 PM ----------

Changing to OPEN causing all kinds of crashes. Use "spr" instead of "SPR" to unlock
[Sprint LG G3] engine95:
If this trick still works, try pressing and holding the "Data" button in quick settings.

That should let you be able to change from CDMA to GSM without a shortcut.

Hi, i bought 2 of these sprint g3. have tried the two methods but no luck first i tried remplacing the files but when i remplace the files and remove all sprint garbage i got full signal but when i try a call it says dialing but i dont hear anything and after +-30 secounds the dialer says "Out of service area" and ends the call.

So i flashed stock firmware over flashtool and changed SPR to OPEN and removed all sprint garbage. and the same i got full signal but when i try a call this time says Mobil network not suported.. and instead of com.android.phone has stopped. i got com.systemui has stopped.

and finally i checked the imeis on the phones and booom :crying::crying::crying: same imei on both = 350305260000004

which is a rare imei and when i checked for bad imei got this: http://www.imei.info/?imei=350305260000004.

[Sprint LG G3] rishidhar:
You won't get errors if you changed to ro.build.taget_operator to spr (spr should be in small letters)
[Sprint LG G3] hatlesssandman:
Ok please try these settings on your phone exactly as displayed in the screen shots. This should give you correct signal bars on your phone and get rid of the dreaded gsm icon (i hate that icon with a passion) and should show H icon if you have 3g or E icon if you have 2g. I've attached a screen shot to display this as well. I'm using this internationally but this should theoretically work domestically as well since after these settings the phone becomes truly global and not the gimped Sprint version. Please provide feedback on this thread to let me know if this works (Im the same person the OP used the phone of as a guide to unlock his as i had mine unlocked from Sprint).

I suggest you use Rom tool box to edit your build prop as there's minimal chances of it going into bootloop then.

So change your ro.build.target_operator to GLOBAL as in screenshot (ALL CAPS just in case) and change ro.build.description as in the screen shot (first line of first screen shot)

Good luck!
