How to Reset a Sprint Samsung Phone back to Sprint
Open Dialer and dial ##RTN# then enter your MSL/SPC Code (Most likely is 000000 if it has been flashed before
You most likely will need to also put a Sprint PRL on the phone also if you are not using the Sprint Corporate PRL
If so you can use this one and it should work fine:

Android 4.3 Upgrade Methods for Verizon and Sprint Phones
DO NOT DOWNLOAD THESE FILES AND ATTEMPT UNLESS YOU ARE 100% SURE YOU KNOW WHAT YOU ARE DOING
THIS WILL LOCK YOUR BOOTLOADER FOREVER NO GOING BACK TO PREVIOUS VERSIONS EVER
Let me stress that anytime you flash either with ODIN or normal methods you take the chance of BRICKING your device.
SO be sure you know what you are doing as I am not responsible for anything that may go wrong.....

Things Not To Do With A Flashed Phone
1. NO OTA Android Updates Period (You will break your flash)
2. No OTA Programming *228, *22890, *22800, *22801 or any other Variants
3. Some Rom's do not play well with Flashed Phones do your research before flashing.
4. Never do a RTN (Return to Network) Reset ##786# on a Flashed Device (Most definitely will break your flash)
5. Some Radios/Modems cause issues if you flash (If the phone is working leave it be)
6. Factory Reset ( I recommend not to do this also, some versions of Android phones it will break things period)
7. PRLS ..... aww my favorite, everyone thinks these are the answer to all their prayers
a. If the phone is working leave it be (my personal stance)
b. Some PRL's are not EVDO or have not been Modded and will break your 3G or throw the Roaming Symbol
c. I have posted many PRL's above that will work with 3G (Latest one I modded is 60007 for all carrier phones)
8. No Phone Number Change (You change your carrier assigned number, you must reflash)

Why Is My 3G Data Slow?
It's a complaint I hear everyday from people using flashed smartphones performed by them or another flashing provider...
Why are my speeds so slow and is it possible to improve the situation?
There are a variety of reasons why 3G data speeds may be less than stellar, and each one requires a different solution.
Before assuming there's a problem, though, make sure you understand the realistic capabilities of your service.
VERIZON/Page Plus/Selectel:
2G 1xRTT: 50-100kbps download and upload with bursts to 144 kbps
3G EVDO Rev-A: (shows up as "3G" on your phone): 600-1400kbps download with bursts to 3Mbps, 200-800kbps upload with bursts to 1.8Mbps
(Don't get to caught up in running speedtest as these can be very confusing and fool you at times into thinking you have a problem when actually
the way they test and the servers they use get congested also)
POTENTIAL PROBLEM #1: Weak signal
If you're too far away from the tower (or if there are a lot of obstructions/interference between you and the tower), your device won't be able
to pick up a strong signal and your performance will suffer.
Solution: Try other locations in your home or area you are in, some areas do not get great signal strength and this could be your issue.
POTENTIAL PROBLEM #2: Tower overcrowding (Network Congestion)
The bandwidth available from a cell tower is shared amongst all the users connecting to the tower. A cell tower can only provide so much bandwidth,
and the more users there are connecting to the tower, the slower everyone's speeds will be.
Is this YOUR problem? If you notice that your speeds tend to follow a pattern most days (for example, nice and fast late at night or early in the day but slower in the evening when everyone is home from work and school) and you've confirmed that the problem isn't signal-related (by testing your speeds at home and then again somewhere closer to the tower), you'll know your tower is simply being used by lots of other subscribers at the same time.
Solution: Unfortunately, there's nothing you can do about this (other than consider switching to a different provider who might have more capacity at their towers or isn't as oversold in your area).
POTENTIAL PROBLEM #3: Incorrectly Performed Flash
It's very common for flashed phones to have been done incorrectly.
Is this YOUR problem? This is very possibly the source of the problem if your flash was done incorrectly or you made changes to your setup recently.
Solution: You'll need to either troubleshoot the phone and or reflash the problem phone.
POTENTIAL PROBLEM #4: Tower issues
Providers periodically do maintenance or upgrade work on cell towers, which can disrupt service; other factors like severe weather occasionally damage cell towers and cause problems.
Is this YOUR problem? If your service suddenly degrades significantly and doesn't improve much during non-peak hours (which it would if the problem was overcrowding), and you've confirmed it's not a problem with your flash, the problem likely lies with the tower. The best way to confirm is to take your device several miles away where you'll be connecting to a different tower and test there — if everything works fine when connected to a different tower, you'll know something is amiss with your home tower.
Solution: Out of your control, bear with it until the provider finishes work and repairs.....
Potential Problem #5: Sprint and USSC Devices
I hate to say it but I have seen some Sprint/USSC phones have this issue, likely due to weaker radios and or hardware implemented in the device.
Is this YOUR problem? This is very possibly the source of the problem if your flash was done correctly and you verify that other devices on the network in the same location as yours get consistently better data speeds.
Solution: Verify flash is correct and that your connected at EVDO in settings and passwords have passed authentication. If so this most likely a Sprint/USSC device issue out of control by the user. Replace device with another Cellphone Carrier brand and most of the time problem will be solved. (I see this allot with some of the Samsung S3 Devices from Sprint/USSC, almost like certain lots had a weak radio for whatever reason)
In the end your speeds can be related to any or all of these issues, and a proper flash is key to performing at optimal speeds.
Sometimes as much as we hate to admit a professional flasher is needed to correct speed issues, you would not believe some of the poor flashes I see when I read preflashed phones everyday that so called professionals performed
