How to enable GSM Options and Unlock Boost Mobile Samsung Galaxy phones after flashing Sprint Firmware

The Samsung Galaxy S5 for Boost Mobile and Sprint cellular is the same de device SM-G900P; however, the in Boost Mobile Preferred Network Mode options, the phone only displays two network modes “CDMA and LTE/CDMA; consequently, the Boost Mobile SG S5 cannot be GSM unlocked.

How to enable GSM Options

How to enable GSM Options

The Boost Mobile ROM doesn’t provide options for GSM option, but the Sprint SG S5 does; so in order to enable those options on the Boost Mobile SG S5, we need to flash a Sprint ROM; there may be different methods of doing it, but this is the one that works for me.

Files needed:

• Odin3-v3.0
• CF-Auto-Root-kltespr-kltespr-smg900p.tar 
• Openrecovery-twrp-2.8.3.0-klte.tar
• G900P_OA6.5.0.De-Odexed.Ver1.1.zip (May work with other Sprint De-Odexed S5 ROMs).
• G900PVPU3BOG1_G900PSPT3BOG1_G900PVPU3BOG1_HOME.tar

And Samsung drivers if you do not have those or Kies installed
• Samsung drivers

Steps:

2. Enable USB Debugging on your phone (you must be already familiar with it) if not here is how to do it
3. Load the G900P_OA6.5.0.De-Odexed.Ver1.1.zip ROM file in the phone or in a MicroSD memory card.

Installing De-Odexed Sprint ROM:

16. Boot the phone into custom recovery (Once the phone is off,hold Vol Up + Home + Power).
17. Select Wipe, it goes to another screen.

It’s up to you to double check, but at this point, the Preferred Network Mode Options are already enabled on the phone; thus allowing to select GSM/UMTS and Automatic modes, and of course, the phone is ready to be GSM unlocked.Can be GSM unlocked using Online unlock Sprint Samsung Galaxy S5 SM-G900P 

Installing the Stock ROM:

(I decided to install the stock ROM, for looks, and set the phone to the original Sprint options, but it doesn’t show any Splash screens anyway).
