Unlock Sim for GSM How to

[rishidhar]

This should be the correct one: During the installation of the rom it will ask you for the model of the G3 - select Sprint LG G3 LS990

Proper GSM Unlock LG G3 LS990 with Wi-Fi HotSpot

First off backup all data thats required from your phone.
Restore to COMPLETE stock like its out of the box, Use this LINK
Root the phone using STUMP
Install Root Explorer
Use Root Explorer only, yes its a paid app, nothing is free all the time.
Using Root Explorer go to system/priv-app/ look for LGStartupwizard.apk, rename it to LGStartupwizard.apk.bak -> Sprint users who want the handsfree activation should not do this. Its only for those who want to use the phone for GSM and get rid of "Activate Phone" notification.
Download attached carrier.rar and extract the folder on to your phone, same with apn-conf.rar & Unlock2.rar.
Remember to "REPLACE" the carrier folder and "NOT" copy its content to carrier folder.
Now copy the contents of Unlock2 folder and replace the original files from carrier/apps/ folder.
Change permissions for carrier folder is rwxrwx-x.
Please refer pic for the correct permissions. you need to change permissions of carrier folder only.

Pop in your GSM sim and reboot to see if you are getting GSM signal . There is no APN menu but the G3 automatically detects the APN from the provider and sets it for data.
If not Install Shortcut Master Lite
In search field search for apn, make sure there is not space after apn while searching, Refer pic below.

Select the first result as shown in pic.

Select launch as shown in pic.

You should get the APN menu now, Add your APN and save.
If you still have problems with getting the GSM to work, Replace apn-conf.xml file from the download section and replace it in /etc/ folder, then delete telephony.db file from /data/data/com.android.settings.telephony/database/ , reboot. Follow the manual APN adding using ShortCut Master lite like i mentioned earlier.
Hope this helps.

If it works, cool, but again, that's a million steps more than what is required.

Under downloads look for Generic Lg G3 Dll use this DLL for your problem.

This was very helpful however the process went through and got stuck on the factory reset screen the error message returned was (USB PORT OPEN FAIL) Any suggestions????: confused:
thanks in advance.

Oh Man, its a bug on the Flashtool, just press ok and let i flash !!
When you select the yellow arrow, you might get a popup saying "MilkyWay Control Port Open FAIL"
just select ok as shown below in pic.

If by "recently", you mean 5 years ago, then yes I suppose I "got on Android recently".

My post was saying that your method for unlocking the LS990 is overly complicated. I've done many of them and none of the steps that you posted are necessary,

I did not mean to insult you in any manner, but for a person with 5 years on Android this will not take more than 10 mins .

The build.prop edit works but has many glitches, the one which i explained does not have any glitches. Have a great weekend sir

I have used this guy several times here in the states without issue. (about 2 dollars)

He is also a member here...
Good luck

Unlock code sites can only generate codes for GSM phones. Sprint phones are not GSM and do not use unlock codes

Did not see the "Sprint" word anywhere in his post?

BTW: The last time I called Sprint and asked for a unlock code they knew exactly what it was and provided it

1. We are in the SPRINT LG G3 forum and this is a thread about unlocking the SPRINT G3.

2. Sprint phones do not use unlock codes. The code they give out is the MSL (also called SPC) which only allows for CDMA programming and does nothing for GSM use. There is no way to force a prompt for a GSM unlock code on a Sprint phone because a code doesn't exist.
