I am not going to explain how to unlock each device so dont waste your time asking. But I am going to tell you all the procedure to sprint domestic unlock all samsung devices supported by z3x

most devices:
all you have to do is turn adb on and connect to the box and click domestic unlock.
after you must go into settings of the phone
mobile networks
preferred network time
GSM ( automatic works, but not better than GSM)
if no network after,
after you must go into service mode and turn on gcf mode
which is explained in many threads (*#0011#)

IF YOU CANNOT GET INTO GCF MODE (*must have root*)
1. ROOT THE PHONE WHICHEVER WAY YOU WANT TO HAVE ROOT ACCESS
2. DOWNLOAD APP CALLED "PHONE INFO" FOUND HERE OR PLAY STORE Phone INFO ?Samsung? 3.4.3 APK
3. CLICK MENU BAR IN TOP LEFT CORNER
4. CLICK OTHER TOOLS
5. CLICK SERVICE MODE (ROOT)
MUST HAVE ROOT FOR THIS TO WORK
AND FROM THERE YOU CAN ACCESS GCF


IF YOU TURN GCF ON AND STILL NO NETWORK OR NO ROOT APPLICABLE
NOTE 4- I DOWNGRADE TO 4.4.4 AND IT WORKS RIGHT AWAY
GALAXY S5- FLASH A DIFFERENT MODEM FOR BYPASS MSL
NOTE 3- FLASH A DIFFERENT MODEM

THESE ARE THE ONLY 3 DEVICES THAT I HAVE EVER HAD ISSUES WITH.
ALL IVE DONE HAVE BEEN ONES THAT WERE BAD ESN SO THIS WORKS GREAT!!!


4G PROBLEM
I have not been able to show 4g instead of 3g. but one thing I know is when sprint devices are put into roaming mode, it shows 3g. When these phones get unlocked they are basically put into roaming mode, and by checking the data speeds especially with t-mobile the phone is very fast, much faster than 3g speeds! SO WHO CARES WHAT IT SAYS AT THE TOP LET THE CUSTOMER KNOW IF THEIR PLAN CONSISTS OF 4G DATA, YOU WILL GET IT!

SPRINT DEVICES ON METROPCS
I have had no luck at all using these sprint devices on metropcs as you must pair the sim with the imei and they constantly reject sprint imei's which is bs but hey, if anybody figures it out let me know!!!

if anybody needs anything else explained just inbox me and I will be glad to help. Soon I will be placing step by step tutorials on youtube so be ready!!!
Thx for all that I unlock note 3 sprint 3 m a go and I activate it for the customer
Under metro and it work without no prblome also the Internet Signal is better than CDMA phones It's shows H PLUS SO SPEINT WORKS WITH METRO
