Hi guys, I know galaxy s5 has been there for a while now but yesterday I tried more than any other time to do this and it worked at the end!
REQUIREMENTS:
UNLOCKING PROCEDURE:
MORE HELP:

Troubleshooting:
Unlock S5 without root *Fully Free

REQUIREMENTS:
- Galaxy S5 (duh?) (tested on G900T)
- z3x Samsung Tool PRO v28 or 29 (v24 didn't work for me) (With crack! search google to find it. I'm not going to post crack link on xda)
- 4.4.4 Firmware! [G900T -AndroidFileHost] (need 4.4.4 because on 6.0 it doesn't unlock)
- 6.0.x Firmware! [G900T -AndroidFileHost] (update when finished unlocking)

[COLOR="RoyalBlue"](IF your device model is not listed, DO NOT be afraid to try it. It should work just fine on your S5 too)[/COLOR]
- (Important but optional) Make a full backup using any way you prefer (TWRP/CWM.. / Titanium backup / whatever..)
- (Proceed with caution!) Go into TWRP/CWM and Wipe System, data, and caches
- Flash 4.4.4 - Use odin or z3x to flash the firmware (Scroll down for more help)
(Wait for the device to boot) - Dial *#0808#
- Choose "DM + MODEM + ADB"
- (On your PC) Open z3x pro
- Choose model (mine is G900T)
- Go to Repair tab
- Select USB port (something like samsung) and select ADB device
- Click Activate DIAG
- (On your S5) Allow adb access on your phone and wait...
(Phone will reboot automatically so don't interrupt) - (Now in z3x) Go to Unlock tab
- Choose USB port again (something like samsung)
- And Click Unlock
- Now update to 6.0 using odin or z3x
- DONE UNLOCKING :good:
- ENJOY ANY SIM CARD

- Using odin: http://rootmygalaxy.net/how-to-install-a-stock-firmware-using-odin/
- Using z3x: Choose model then go to Flash tab and pretty much the same thing as odin
Troubleshooting:
- Binary error while inserting firmware into odin:
-> Rename firmware from tar.md5 to tar only if you are sure you downloaded the right firmware for your device
- The system cannot find the path specified in z3x:
-> Manually create the path that z3x is trying to reach (this happens when cracked, happened with me at least)
- ... Sorry I don't have more in mind at the moment... :silly:
