[Sprint  Galaxy Note 4 General] Trex888:
You cant flash kitkat official firmware cuz your bootloader is locked .you can flash 5.1.1 lollipop or 6.0.1 Flash 5.1.1 lollipop n910p firmware.its faster then marshmallow 6.0.1

Try this lollipop firmware flash in odin link below

https://www.androidfilehost.com/?fid=24591020540821805
[Sprint  Galaxy Note 4 General] vkitchai:
So the revised process is

1) Download OF1

https://www.androidfilehost.com/?fid=457095661767098816

2) Download TWRP for N910P

https://dl.twrp.me/trltespr/

3) Download SprintxnoteRC2

https://mega.nz/#!jdsmEAKa!FH3RvThxg...9RcNmBGJi3Ly7M

4) Flash OF1 via odin without reboot then flash SprintxnoteRC2 via TWRP
[Sprint  Galaxy Note 4 General] Trex888:
Flash kitkat developer bootloader/baseband file in odin and flash this kitkat rom in twrp

Hi. Thanks for your effort and for making this thread. I have successfully downgraded to developer firmware, flashed the old 4.4.4 rom you indicated and unlocked the sim by running SSU.apk. I have now upgraded to stock 5.1.1 and the sim unlock sticks. Thanks so much!
[Sprint  Galaxy Note 4 General] NH2CH3:
Hi [MENTION=7617599]Trex888[/MENTION]

Thank you for sharing this. I've a network locked n910p, runnning on latest MM firmwre.

I'm gonna try this way to fix my problem, I hope it'll work, I'll let you know in the next few hours :)

Fingerprint Scanner Issue

Guys, can anyone confirm whether fingerprint scanner is working in XNoteRC2 or not..?
[Sprint  Galaxy Note 4 General] mikexmayhem:
the modem/radio on kit kat (using Echoe Rom) is much worse that i remember seeing on MM. is there a better radio that can be flashed on KitKat?
[Sprint  Galaxy Note 4 General] Ind3lible:
I can downgrade this way if I want to just go back to kit kat and don't need unlocking? I will be using the phone on sprint still!

Thank you!
[Sprint  Galaxy Note 4 General] robinhood1808:
I'm using a GSM SIM with this N910P. For me, the network reception seemed better that MM on XROM.

Only PG1 in MM update is very good in terms of network reception.
[Sprint  Galaxy Note 4 General] Trex888:
Yes you can downgrade without unlocking .i mentioned about unlocking for those who use gsm sim only and their network is locked . for sprint sim users just flash developer firmware then twrp and flash any kitkat rom based on sprint note 4 with custom kernel like ael.
[Sprint  Galaxy Note 4 General] robinhood1808:
The ROM would have been perfect if fingerprint scanner had worked.... Alas, that's not the case...

Otherwise, KitKat is way smoother than current Marshmallow build.
[Sprint  Galaxy Note 4 General] Trex888:
Guys can anybody conform that fingerprint is working with any 4.4.4 kitkat rom.if anyone able to fix this issue report back here and please let me know.
[Sprint  Galaxy Note 4 General] Ind3lible:
Is the second link to a kit kat rom? It says "SprintXnoteRC2old.zip" I can't find any for some reason in the rom section for the sprint note 4..? Or am I not looking in the correct place? If the second link is a rom does it include the Ael kernel? I am just about to flash this :fingers-crossed:

Thank you!
[Sprint  Galaxy Note 4 General] Trex888:
Yes it's allready included ael kernel.you dont have to flash any custom kernel. the sprintxnoteRC2 rom is in the 3rd link.
[Sprint  Galaxy Note 4 General] Ind3lible:
Thanks man !!!????????????
[Sprint  Galaxy Note 4 General] robinhood1808:
I guess not... Had tried a stock based ROM from tx and the fingerprint did not work even there..
[Sprint  Galaxy Note 4 General] Trex888:
Flash 5.1.1 og5 bootloader only without modem and flash Nadia kernel 4.4.4 in twrp and it will work with any kitkat rom and it's confirmed I test it.I am running dynamic Kat v4.1 and everything working including fingerprint.I tested with 6 different roms and all works with fingerprint.
[Sprint  Galaxy Note 4 General] shadowcliffs:
Is the Nadia kernel 4.4.4 you mentioned for N910P? I can only find it for other variants.

And the Dynamic Kat 4.1 is not for N910P, right? I can't find anything except for Dynamic Kat 4.2 for N910T.
[Sprint  Galaxy Note 4 General] Trex888:
Dynamic kat is for n910t but it works with n910p whth nadia kernel and nadia 4.4.4 kernel works with all snapdragon variants 4.4.4 roms i tested on n910p n910t n910f n910v.

You can flash any sprint based kitkat rom along with nadia kernel it will boot fine with og5 bl and fingerprint will work.

I use tmobile and international roms cuz i do not live in usa and i dont use sprint sim card so i can't activate profile i have to stick with other variant roms.
[Sprint  Galaxy Note 4 General] robinhood1808:
Can you be please bit more specific, [MENTION=7617599]Trex888[/MENTION]?

Throw some light on following points:

1. OG5 boot-loader should be flashed after flashing the required boot-loader & ROM as stated in OP or otherwise?

2. Kindly share the link to the Nadia kernel. Also, the link to the dynamic ROM that you are using..
[Sprint  Galaxy Note 4 General] Trex888:
If you want to just run kitkat roms you dont need to flash developer firmware.

Just flash og5 bl in odin and nadia kernel in twrp

Developer firmware is just downgrade bl and modem for temporary basis unlocking sim card network cuz with og5 5.1.1 bl & modem unlocking with ssu apk won't work.

I'LL upload the kernel link and rom that i am using and dont forget to thanks kernel & rom dev

Download link below nadia kernel

[Sprint  Galaxy Note 4 General] aRandomPiece:
I'm confused. Can you downgrade from Marshmallow and unlock, then go back to MM?
[Sprint  Galaxy Note 4 General] Trex888:
Yes you can

Downgrade and Unlock with kitkat

The unlocking will stick permanent with any rom or firmware
[Sprint  Galaxy Note 4 General] aRandomPiece:
I flashed this file, and when the phone started to boot into recovery it rebooted and went to a "User Fault Upload Mode" screen. Help?
[Sprint  Galaxy Note 4 General] Trex888:
Flash twrp via odin

Flash any kitkat rom

Flash nadia kernel

Please read original post carefully all answers are there

You can't boot into developer firmware its empty you just have to flash to get kitkat bootloader
[Sprint  Galaxy Note 4 General] aRandomPiece:
Ok. That's what I was doing. It just wasn't letting me get into twrp. It every time the twrp screen would show up, it would reboot and go to that error screen. I was finally able to get into twrp by just holding home/power-up and letting it reboot a couple of times until it finally went all the way into twrp.

One more question. Where do I get the nadia kernal? I didn't see a link to it in the op, and when I searched for it, I only saw it for other models, not for the n910p.

Thanks again
[Sprint  Galaxy Note 4 General] aRandomPiece:
Ok. I've completed all steps and still get the "invalid sim card" message. I've read on some other sites that SSU will not work with American carriers. I've tried with both American AT&T & T-Mobile sim cards without any luck. Could this be my problem? I've also tried the gt galaxy tools and the ##72786# processes. GT Galaxy Tools and SSU are both saying the phone is (SIM) unlocked, but I'm getting the error. Is there something else I can try, or am I out of luck?

Thanks
[Sprint  Galaxy Note 4 General] Trex888:
Flash developer firmware

Flash twrp

Try flash diffrent kitkat roms if the 1 in 0p doesn't work.

Try n910t based rom with nadia kernel.

It should work with ssu.apk.

Make sure reboot after unlock with ssu.

Everyone so far success with this method.

Be patient and try again.

Once it's unlocked it will stick permanently no matter which rom or firmware you flash.
[Sprint  Galaxy Note 4 General] Seven13:
Can´t get ssu or gtools to work.. I´ve completed all steps, I´m on 4.4.4, rooted, but neither ssu or gtools dont run.. Any help?
[Sprint  Galaxy Note 4 General] Trex888:
What do you mean don't run ?

Please be more specific
[Sprint  Galaxy Note 4 General] aRandomPiece:
I've tried different n910t based roms with the nadia kernal and still am getting the invalid sim error. SSU already says it is sim unlocked when I open it up each time, and gt galaxy tools says it is unlocked as well. So it's almost as if it looks like it's saying it worked, but it's just not accepting either of my SIM cards (T-mobile or AT&T). Does this make sense?
[Sprint  Galaxy Note 4 General] Seven13:
This..
[Sprint  Galaxy Note 4 General] Trex888:
Well looks like you have root issues

Both of this apps required root permission

When you open this apps it should be black like in the screenshot but it should popup supersu request. Once you grant roor permissionthe apps should work fine

Try flash supersu larest version from recovery

Uninstall both apps and install again

Open and grant root permission they should work fine
[Sprint  Galaxy Note 4 General] Trex888:
Thats weird bro

This method working 100%

Maybe you have some hardware issues in sim slot

Tell me your phone accept sprint sim card or not?

When you insert sprint sim card if it says same invalid sim then i suggest you should you go to repair centre.
[Sprint  Galaxy Note 4 General] Seven13:
Root is granted on other apps.. Xposed, etc..

I am using Dynamic Kat 4.1 and AELKernel. Still can get ssu.apk to work..
[Sprint  Galaxy Note 4 General] Trex888:
Flash the rom in the op sprintRX2 kitkat

I have tested on that rom and its working with ssu

After unlocking flash any rom you like.
[Sprint  Galaxy Note 4 General] Seven13:
Can you give me any link for the rom?
[Sprint  Galaxy Note 4 General] Trex888:
https://mega.nz/#!jdsmEAKa!FH3RvThxgDj_gnxCDgrEAyZi-n3R19RcNmBGJi3Ly7M

Dont flash any kernel

Just flash rom and flash supersu.zip latest version

When rom boots Just skip setup

Let phone rest for 10 minutes and install ssu.apk

Make sure you are connected with WIFI

Press unlock and grant permission

Reboot device and you should be good to go.
[Sprint  Galaxy Note 4 General] eswar67:
I Did all steps mentioned above and it is showing in SSU and Galaxy tools as Unlocked and UICC unlocked..After inserting sim simtoolkit is detecting what ever sim i insert like Airtel or Lycamobile..But no signal bars are appearing..Tried multiple roms and many menthods but not able to fix..Please suggest me a fix I can really appriciate with sending some donation to one who resolves my issue..not able to use my phone from last 20 days..
[Sprint  Galaxy Note 4 General] Trex888:
Did you get pop up in notifications ( invalid sim card ) ?

Or just not getting signal bars no reception ?

If invalid sim card not showing in notification then try this method.

1,Flash 5.1.1 lollipop n910p firmware in odin.

2,After flash go to stock recovery and wipe cache and data factory reset

3,let the phone boot and skip setup

4,Once at home screen open dialer

5,dial ##72786# and press YES

6,wait until phone will reboot automatically

After reboot you should get signal bars and sim unlocked.

Hope that helps

Report back.
[Sprint  Galaxy Note 4 General] Seven13:
The phone does not boot.. I get "modem crash".. Any idea?
[Sprint  Galaxy Note 4 General] Trex888:
After flash developer firmware Go to twrp and make full wipe

(Dalvik cache/cache/system/internal storage/data)

And flash rom again.

It will boot hopefully
[Sprint  Galaxy Note 4 General] aRandomPiece:
When the Sprint sim card is in the phone it doesn't say invalid sim.
[Sprint  Galaxy Note 4 General] Seven13:
Still no success.. I get no modem, and the ssu.apk now works but has no effect.. Did I miss something?
[Sprint  Galaxy Note 4 General] Trex888:
I'll give you bootloader and modem of developer firmware instead of whole developer firmware

Flash this in odin

https://www.androidfilehost.com/?fid=457095661767098816

Once you finish flash dev bl/modem in odin flash twrp latest version

Go to wipe and wipe everything except microsd card

Flash the sprintxRC2 rom

And follow the same prosidure with ssu.apk

Hopefully this time you will have modem working.

Thanks to [MENTION=5695250]shadowcliffs[/MENTION] he extrated the bl/modem from developer firmware.
[Sprint  Galaxy Note 4 General] Seven13:
The link is about the whole firmware.. the same I've flash yesterday.. is that suppose to be?
[Sprint  Galaxy Note 4 General] Trex888:
No the link of bl/modem file that i gave you today is around 120mb

And the dev firmware is around 600+mb

So much better you flash bl/modem instead of whole firmware.

Try flash 5.1.1 firmware and then flash dev bl/modem file then twrp

After that start from beginning the whole process.

Be patient once its unlocked it will stick permanent with any rom or firmware.
[Sprint  Galaxy Note 4 General] eswar67:
for me invalid sim card is not showing in notification as my phone is unlocked already.

I tried your all steps and still not getting network bars.

But in available networks search it is showing few other networks but not my mobile network.It is showing TDC,3.DK,Telenor,Telia only these networks.Mine is a nano sim i am using with Micro sim adapter is that an issue?also mine is 4g sim is it causing some issue?also my MSL code is showing as 000000 is it fine or something is corrupted? any other things can i trouble shoot?
[Sprint  Galaxy Note 4 General] Trex888:
Open dialer and dial ##72786# and press YES then reboot.
[Sprint  Galaxy Note 4 General] eswar67:
As I mentioned I performed this step(pressing ##72786# with multiple roms including 5.1.1 stock rom..but no signal bars...also when i do this step prefered network going to LTE/CDMA i am switching to GSM/UMTS and also to automatic still no luck...can you connect to my mobile using samsung quick support or team viewer app so that you can access my phone?I am feeling you can resolve this issue..Some thing I am missing but I followed all your steps..Really appreciate if you can spend 5 mins of your time

---------- Post added at 09:25 PM ---------- Previous post was at 08:44 PM ----------

As I mentioned All these steps not resolving my issue..I went to local mobile repair guy and he relocked my phone resetted it and unlocked the phone with Samsung Pro tool kit..Still same issue and finally he told it might be EFS/NV data corrupted and need to have other working Note 4 to read it and back it up to my mobile..But not sure what he tells is correct or not..Do you have any idea about it?
[Sprint  Galaxy Note 4 General] robinhood1808:
[MENTION=349802]bold[/MENTION]: This code is just the right way to get the network bars on a Stock ROM.

People should thank [MENTION=7617599]Trex888[/MENTION] for this.
[Sprint  Galaxy Note 4 General] Trex888:
Dial *#06# and if imei shows here then nothing is wrong

If imei shown null then yes its its corrupted and your efs is messed up.

Go to settings/about device/status/imei info/here if imei shows then all good if null then its corrupted

Try flash stock 6.0.1 and see if imei still shows null

Cuz sometimes wrong bootloader can cause imei shows corrupted.
[Sprint  Galaxy Note 4 General] Seven13:
Did all the steps above, but still with no baseband and the ssu.apk dont change unlocking status.. more ideas?
[Sprint  Galaxy Note 4 General] Trex888:
No baseband even after flashing stock 5.1.1 or 6.0.1 firmware ?
[Sprint  Galaxy Note 4 General] Seven13:
Yes.. I've got no baseband after flash one or another..
[Sprint  Galaxy Note 4 General] Trex888:
I suggest if you made efs backup earlier then restore it

Looks like some issue in efs partition.
[Sprint  Galaxy Note 4 General] Seven13:
I didnt have mave any backup.. is there any alternative solution?
[Sprint  Galaxy Note 4 General] Trex888:
Sorry no idea
[Sprint  Galaxy Note 4 General] eswar67:
I narrowed down the issue further..I switched back to 6.0.1 PD1 version and tried with Telenor and Telia sims and both are detected signal and I am able to call from those sims..But not working with my Lyca sim and Airtel sim..The problem to switch to telnor or any other networks are subscription based operators and they dont provide India calling facility or else switched to those networks...So issue is not with unlocking and IMEI some thing is missing..If you know what it is please let me know...

I've done all of the steps several times over and still get "invalid sim card" even though SSU continues to say the phone is Sim Unlocked, and Galaxy Tools says it is unlocked as well. One thing I have noticed is that SSU has never asked for permissions like your instructions say it will when unlocking. Galaxy Tools does ask for root permissions. I've tried a T-Mobile sim card as well as multiple AT&T sim cards. The phone just keeps trying to go through the Sprint Activation process.

If there is no way for me to get the phone unlocked, is it possible for me to go back to the stock rom?

i also have a lg g4 sprint unlocked and its actin weird on verizon to i get 3 g but i dont think the sprint varient supports verizons lte band it shows on the sig bar im roaming but in network im not.

technicly verizon is a cdma carrier but there lte is on a sim i dont know if thats considered gsm or not but its working half assed on my g4.

im in no rush on this one the note 4 has a bad battery it jumps all over the place on percentage and i gotta redo the iemi as it was blacklisted on sprint do to non payment of easy pay. i bought it for parts cause it wouldnt come on at all.

it was stuck in qloader and decied to work it may have the dreaded emmc failure starting but once i get it booted up it seems fine just a quick hard draw like 10 % with in 10 min itll be at 90 ill restart it itll say 55 then ill restart again anf might br 85 it jumps all over the place

[Sprint  Galaxy Note 4 General] planb234:
I got a bad MD5. Usually it will start and fail if my bootloader rejects it. I was excited too. I really wanted to get the bottom bootloader again. It's weird how everyone has something work a little different. I went back to kitkat once. I wish I stayed or I could bounce back and forth. When I went back I odined the stock firmware. I'm not sure which thing made that happen - the FOTA, the cache partition from auto root, other crazy things I flashed (I was even dumber 2 years ago), or the accidental trying to down grade that locked me into being only able to use my Bob7 backup for 6 months. When I was on 5.1.1 I accidentally hit restore on kitkat back up. It was no good. After days of trying everything the one back up with the plasma kernel would work. Everything went back to normal at the next update with a new boot loader. We've only got like one more of those coming so I'm kind of scared. I heard PIT files do something to straighten out bootloader issues. I just barely was able to find one for the (P) all tough now I'm not sure it is since this gave me a bad md5. I got the pit files of my phone afte weeks of looking for it I could only find an extraction method.

I know exactly what one BLs I need to hang on to but the other ? I'm top scared to try and back them up. If anyone has method of unlocking or replacing please share. I think getting those back to stock and cleaned out would mske a tremendous difference.
