I have a sprint samsung galaxy s4 sph-l720 im

Sure is as long as you didnt screw the carrier over that issued you the phone they will carrier unlock it at one of their service stores. You can as well send it to one of those fly by night online places take a chance on them stealing it or bricking it. However to answer your real question NO without a pc you can not carrier unlock ANY cell phone.

Good files that have been used successfully to flash Verizon Motorola droid x 2 to Boost Mobile. Of course it can be done, I just need reliable files that have been successful in the past. They gave up...

The Droid X cannot be flashed to GSM carriers such as ATT or T-Mobile.
However, the Droid X can be flashed to carriers such as Cricket via QPST and CDMA Workshop.
The Droid X also cannot be flashed to Sprint even though it is a CDMA carrier, they use conflicting radio hardware. So theoretically you could have voice and text, but not data.

Need to unlock cricket galaxy s so I can use it on MT straight talk plan

US Cellular phones each come with unique SPC/MSL codes. To "unlock" it you must find out the SPC/MSL code and change it to all zeros. After you unlock it, you would then need to install a new prl file that corresponds to your new carrier. Only then can you activate new service with another carrier.
There are Windows programs out there that will let you do this (e.g. CDMA Workshop, DFS, QPST, QXDM).
If you use QXDM software, here's a quick link for the commands:

I have somehow locked the keypad on my LG Banter it is a prepaid phone as such i have no account number or I do not receive a bill and I have no idea how to recover this 4 digit code to unlock...

Here is your solution:
1. Download CDMA Phone Tools
Here: ""
2. Install and launch the program. When I did, it set my antivirus off but after some reasearch it appeared to be okay. After I used it, it didn't damage my system so I don't think it was a virus. However, use at your own risk.
3. Plug your phone into your computer and let windows find the drivers. If for some reason windows doesnt find the drivers you can get them
here: ""
4. Once the phone has installed in windows run CDMA Workshop. I had to click "run as administrator" or it wouldent launch, I'm running windows Vista 32 bit.
5. Once CDMA Workshop has launched set all baud rates to 38400 in the Com settings, AT mode and DM mode should both be set to 38400.
6. One at a time starting with COM1 try each COM port and hit "connect". If it is successful it will tell you at the botton it has connected to the COM port. If there is nothing there it will tell you it failed. If it fails try the next one till it says connected.
7. Once you have connected click the "Read" button. If it tells you "Failed.. Phone Does Not Answer" you have the wrong COM port. Click "Disconnect" select the next COM port number and repeat until you see a bunch of info pop up on the left.
8. I was not able to pull the unlock code by clicking "Read", I had to use the one of the 3 buttons under the "DM Mode" Section. The button "LGDM" worked for me, I honestly don't know what the other 2 do.
9. Look to your left and WALA! you should have an unlock code displayed.
10. Thank me, because my fingers bloody hurt now. lol
Hope this helps you out and everyone who is stuck on this, it took me hours of reading and compiling info to figure this out.
Take Care

How to get MSL for samsung Instinct

you need a cdma reader for this. i wouldn't recommend unlocking your phone yourself. it's not as easy as some people think and even if you're as careful as possible, you can completely ruin your phone. i've unlocked many phones for many people and i always see that one common mistake... people thinking they can do it themselves.
