[Sprint  Galaxy Note 4 General] Trex888:
warning

This method will not work anymore if you upgraded to QI5 new bootloader/baseband because it's locked to binery 5 it's impossible to downgrade and dev firmware will fail in odin.

This method will only works with older bootloaders only before QI5

I have successfully downgraded to kitkat after pull my hair for days and unlocked for any sim worldwide if you guys like kitkat like me and wanna unlock your sim network follow these institutions.

1,download developer kitkat firmware and flash via odin 3.10 this firmware is for developers without user apps and its empty but good thing is it will let us downgrade to kitkat bootloader no matter you are on 5.0,5.1 1,6.0.1 just flash.

2,after flash developer firmware dont let phone boot immediately go to download mode and flash twrp recovery.

3,after flash twrp recovery flash sprintxnoteRC2 kitkat rom this will boot flawlessly to kitkat.

4,if you like to try other n910p based kitkat roms go to twrp and backup (boot) thats your kernel of sprint xnote RC2 rom before flash any kitkat rom cuz i donno somehow kernel of sprint xnoteRC2 let boot every rom successfully without any errors.just after flash any rom immediately go to twrp restore and restore (boot) kernel that you made earlier from sprintxnoteRC2 rom.

4,FOR UNLOCKING download SSU APK this will work with kitkat if your phone says INVALID SIM CARD just install as normal APK and open it will ask for root permision PRESS GRANT and unlock then reboot if still your phone dosent get signal bars then go to dialer and dial ##72786# and press YES it will reboot automatically your phone and hopefully you will have signal on gsm sim. if SSU apk method does not work download gt galaxy tools apk and unlock.grant root permission to galaxy tools and open app go down and you'll see UICC unlock just hit and restart device . also you can unlock tethering hotspot permanently from galaxy tools . THATS ALL. I AM SHARING YOU GUYS MY EXPERIENCE I HAVE TESTED THIS METHOD ON MY DEVICE AND i HAVE SUCCESSFULLY UNLOCED MY N910P AND DOWNGRADED FROM 6.0.1 TO KITKAT

I MADE THIS THREAD SPECIALLY FOR NETWORK LOCKED N910P USERS TO TEMPORORY DOWNGRADE TO UNLOCK NETWORK. BUT IF YOU END UP USING KITKAT ROMS THE FINGERPRINT SENSOR WILL NOT WORK.

FIX FOR FINGERPRINT

Flash og5 5.1.1 bootloader only along with with Nadia 4.4.4 kernel flash in twrp and you get everything working with any kitkat rom.

Or flash 5.1.1 6.0.1 stock firmware the fingerprint will work fine and unlocking will stick permanently
