-help- SM-N910f with SM-N910p bootloader

Hello every one
I have bought a Note 4 " SM-N910f " from ebay and when I tried to root it ,I have found that the version of the bootloader belong to another Note 4 (910p).
about device
Model Num: SM-N910F
Android Ver: 5.1.1
Baseband V: N910FXXU1COH4
Build Num: DONGCHAO.A929
CpuZ
model : Samsung Galaxy Note 4 (SM-N910F)
Bootloader :N910PVPU4COG5
Kernel Ver: 3.10.40-5303209(N910PVPU4COG5)
Build Num: DONGCHAO.A929
Odin mode
product name : SM-N910P
current binary: samsung officiel
system status : officiel
reactivation lock off
Knox warranty void : 0x0
the ticket on the back also show the same thing as ''About device''
but when I cheket my IMEI in ""imei.info"" it tell me that my phone is a galaxy s6 edge !!!!
the same IMEI in both (back ticket & software (#*06#))
so what should I do?
because I can't root neither flash a new firmware
Can I relace the bootloader by the one of N910f ?
(I have only try to flash the firmware of N910f ,I did not try n910p firmware's because I am afraid if I succeed I'll finish with locked network phone)
thanks a lot

have same problem. did you succeed to resolve the issue?

I realised that someone has been changing "Sprint Note 4" to look like the international version.
so I decide to install the latest stock rom ( downloaded from sammobile)
Now I am so glad because I didn't get any problem.
I don't Know how but a Note 4(n910c) IMEI was restored not an IMEI of n910p according to "Imei.info"
Hotspot and Network unlocked including LTE

Hi, I am having the same problem as you.
Can you please give me the rom that you used? And which odin version did you use?
thanks.

what version is the modem? when the moden is from n910p too then its a n910p spoofed as n910f. that can be done by changing backcover and mount a sim reader and it works like n910f. so you have a n910p mainboard in it with changed imei with jtag box

Do this only if your bootloader is a N910P**** (Use CPU-Z to check it, you can download it from the market)
You must have a least 60%
You should remove your SIM card
I've used the latest rom from this link.
http://www.sammobile.com/firmwares/download/60440/N910PVPU4COJ6_N910PSPT4COJ6_SPR/
I assume that you've already installed Samsung driver
and that you have the latest version of odin v3.10.7 and that you're familiar on how to use it
but before you proceed you have to :
1- Instal a custom recovery (Twrp)
http://forum.xda-developers.com/not...nt/tool-utility-twrp-2-8-1-0-teamwin-t2915591
2- boot into TWRP
3-in advanced wipe dalvik cache
4-wipe data/factory reset
5-Format /cache
6-Format /system
7-Format /Data
8-go to advanced and reboot to download mode
9-flash the downloaded rom
wait (10-15min) until your device come to world
Now you have a fresh and clean note 4
10-check your IMEI (*#06#) in http://www.imei.info/
11-restrict data and wifi usage for the following app
Sprint ID
Mobile Installer
Sprint Zone
MyScript Resource Manager
12-Update Your System (settings > System Update > Update Now)
Because this is not the latest build You should upgrade to N910PVPS4COK1 (150mo)
to correct some issue with Google Play Store and other things
13- Update you Play Store and Google Services thru the Store
14- shutdown your device when finished
15-insert your SIM and wake up your Note 4
16-you should root it to profit
(remove unwanted sprint apps it's recommended check the forum to find them out -Use Titanium Backup pro #1 )
enjoy and wait for the Marshmallow =)

Hi.
So how to I get the phone to work? It is in a bootloop when switched on and I cannot go into recovery mode since the phone restarts itself when I try to do so. However I have access to download mode.
Also how do I check the version of the modem?

hello, how do I make sure if my bootloader is a N910P? I cannot download CPU-Z on the phone since the phone is in a bootloop and not switching on.
Before I had the problem, it was written SM-N910F in the about device of the phone. In download mode, it is written N910p and at the back of the phone it is written Sm-N915F.

If you can access the download mode, you simply flash the custom recovery and follow the instructions

you can get it working by flashing n910p rom with odin (download it from sammobile) after that i can say you how to get it again full working with a n910f rom so that you dont have anymore any sprint apps on it

Oh dear ! Thats not a good sign.your motherboard is acting crazy.try flash twrp again in odin and try to flash rom without wipe cache or dalvik cache (just wipe system) and flash rom.
If same error ( invalid argument) shows again then in twrp advance wipe there is repair tab at bottom in twrp try to repair cache partition and try again.

You can try twrp by travis82 here.

It has been confirmed that it works for variant devices like yours. Good luck.

Are u sure that this will work for c9008
Since there is no reference to c9008
Only to c9000
You sure this will work?

can i just flash this rom using odin?

I'm using same model C9008 and already applied it and using to post this reply so it's safe if you know how to do.
You can't use odin to flash custom rom because it's file is in differnet format.

I too have samsung c9 pro sm-c9008 (china variant)
only marshmellow is available yet, but sm-c9000 roms also supported,and you have the latest firmware and the international apps.
i took a smart switch backup and then flashed twrp (c9ltechn) and flash with LATEST odin then your firmware will corrupt and wont work, but you have taken your backup, then download latest SM-C9000 firmware (i recommend hong kong region, im using too) flash it and restore your samsung smart switch backup.
Now your running the international version of c9 pro. (BUT ROOTING THE PHONE IS ALMOST IMPOSSIBLE)

Proceed at your own risk!
1. Download latest odin tool.
2. Download twrp for china variant: https://twrp.me/samsung/c9ltechn.html.
3. Flash twrp and check if stock rom is not corrupted, if not, nandroid backup.
4. Now wipe everything in the phone.
5. Download rom (nougat), SM-9000 firmware is compatible with the SM-9008 hardware (check my image attached) but download the "hong kong" region firmware. Basically your changing your Asia phone to an international phone.

No. since your changing your rom, the rom your currently using might get corrupted after flashing the TWRP. If it doesn't get corrupted, boot to custom recovery(TWRP) and backup your current rom (BACKUP>SYSTEM).
If your rom is corrupted (when restarting your phone after flashing custom recovery(TWRP) the phone will be soft bricked) but you dont need to worry because you can flash back the new sm-c9000 rom. ?

[Q] Cant flash Stock rom anymore

Hello everybody,
I got a Samsung Galaxy S7 Edge (SM-G935F) DBT version and flashed a Custom ROM (Firmware? idk the difference).
I did that like this: youtube.com/watch?v=_1ofpLHMVvA
Unfortunately there were a few problems there, like the camera is awful now (Bad quality and other camera apps didnt made it better).
So now I want back my Stock ROM. (Yes, Unfortunately I didnt made a Backup)
But I cant get it back, neither with TWRP or with Odin.
At Odin its stops at system.img and fails than and at TWRP I guess I used the wrong Rom because is said Zip file is corrupt!.
The following Stock ROM did I use for Odin and TWRP: updato.com/firmware-archive-select-model?record=2A12F0CE03CD11E7963AFA163EE8F90B
At Odin I unziped it and added it the right way: (BL, AL, CP and CSC).
At TWRP I didnt unziped it and used it like it is.
I hope you can help me there.
I have already made the following:
Changed USB Port
Changed USB cabel
Used Smart Switch
And yes, I can still install custom roms like LineageOS and Resurrection easily via TWRP.
Greetings, Darkatzu.

It is, because you will need no verity opt encrypt to flash too alongside official stock rom in order to use stock rom if you rooted by system modification method, with oreo 8.0 I think no verity zip is not working, so you need to flash latest nougat for your country/region alongside twrp , no verity zip and super su, you can download latest stock firmware for your region from samfirm application or updato, also download odin version 3.13.1, latest twrp recovery, super su and no verity opt encrypt from here on xda forums, first check and enable oem unlock, flash stock rom and then flash twrp through odin, then boot in twrp recovery and flash no verity and super su zips, to get detailed info on above steps search the forums. AND PLEASE TELL WHATS ASKED IF YOU WANT TO GET HELPED.
!! NOTE : IF YOU ROOTED FIRST TIME BY SYSTEM MODIFICATION METHOD, AND THEN INSTALLED CUSTOM ROM, THEN FLASHING STOCK ROM BACK WILL PUT YOU ON A DM VERITY ERROR. ALWAYS REMEMBER TO ENABLE OEM UNLOCK IN DEVELOPER OPTIONS BEFORE DOING ANYTHING!
HAVING OEM UNLOCK DISABLED AND THEN ROOTING VIA SYSTEM MODIFICATION METHOD, AND THEN FLASHING STOCK ROM WILL PUT YOU IN A HARD BRICK SITUATION WITH BOTH DM VERITY ERROR AND CUSTOM BINARY BLOCKED ERROR !!
As far as I know the above situation has no solution if you get into this mess and only a memory swap on board or some box can fix this. I know many users here on xda are stuck on this situation. Some users said they fixed this by using nand erase all and re partition using pit file options during flashing in odin, but I really doubt enabling these options will solve this if not making problems worse. Anyone is welcomed to correct me if the above situation has any solution. BUT THAT IS WHY SYSTEMLESS ROOT IS THERE TO AVOID ALL THIS...

Maybe you are using an older bootloader ? Can't say for sure whats causing it, the method you used above I think required system modifications, but you are using a march 2017 stock rom, so it looks updato don't has V2 bootloader firmwares for DBT, problems may happen when flashing an older bootloader on a newer one, it could also be your pc or other hardware problem, but in case try again and download samfirm from here : https://forum.xda-developers.com/attachment.php?attachmentid=3803841
Enter DBT as your region and model SM-G935F , it will download the latest stock available, be sure option for auto decrypt, check crc32 and binary nature are ticked.
After that check oem unlock and usb debugging is enabled and follow the steps :
1. Put phone in download mode, use original usb cable, and make sure pc usb port is working correctly. Also phone must be charged above 50%.
2. Download odin 3.13.1 from here https://forum.xda-developers.com/attachment.php?attachmentid=4431597&d=1519662712
Latest twrp available https://eu.dl.twrp.me/hero2lte/twrp-3.2.1-1-hero2lte.img.tar.html
Latest no verity opt encrypt https://build.nethunter.com/android-tools/no-verity-opt-encrypt/no-verity-opt-encrypt-6.0.zip
Latest stable super su https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.82-201705271822.zip
3. Put phone in download mode, extract the firmware downloaded above from samfirm tool and put the respective files in their boxes, use CSC and NOT HOME_CSC. Make sure no option other than F.reset time is ticked in odin options. Begin the flash procedure. After it is completed, don't reboot and place twrp zip downloaded from above in the AP tab of odin. After it is completed, stay in download mode and hold power+home+vol down to reboot from download mode and immediately switch to vol up button to boot in twrp recovery menu.
4. In twrp recovery menu, you need to swipe for system modifications or tick read only ( if you previously allowed for system modifications then you can do it again it doesn't matter, but if you previously didn't swipe for system modifications then tick read only and download systemless zip from https://forum.xda-developers.com/s7-edge/development/samsung-systemless-devbase-encryption-t3517178 )
I will recommend this as you won't need to flash dm verity.
5. Now, go to wipe> format data in twrp recovery, after its done, flash super su and system less zip through twrp to get system less root if you don't want to get dm verity error hassle when flashing stock roms OR flash super su and no verity opt encrypt if you already have allowed system modifications. After that reboot. It may take sometime.
Also to note if you never allowed system modifications before in twrp, and you don't want to root either, then you can safely flash stock without flashing twrp or going through further steps.
This is what I could best explain according to my limited knowledge, if you still fail to flash stock in odin, then I am not sure it may be your pc or other hardware problem and you may need a repair box, try checking on another pc or some expert user to help. Good Luck.
These steps are only for installing stock rom back on previously rooted S7 edge devices using custom roms and for rooting a stock rom.. and only applies to SM-G935F

Same error.

Sorry I couldn't be much help. Does it always stucks in odin at system.img? Looks like its a hardware problem in your pc/usb ports or phone's usb jack. Try getting your phone checked by a repairer, flashing from another pc or changing usb cable. Also try running odin as an admin or try with an older odin version. Good Luck

And yes, I changed PC 2 and yes tryed other versions of Odin LIKE where AP is named as PDA.

Strange thing if you could flash recovery but not the stock rom, looks like you need to get it checked by a tech. But as a last resort did you tried using pit file and repartition ticked? To get the pit file extract the CSC file and you will find .pit file there, open pit tab in latest odin and select that pit file, then tick repartition box and proceed to flash with all other files selected in their respective boxes. If its still the same then I guess I can be of no more help. Cheers !
!! Warning : Using pit file is never recommended and it could brick your phone permanently if there is any power outage/usb disconnection during flashing with pit, it is used to correct file system partitions if they are changed/corrupted. Its better to outweigh benefits with potential danger. Also a pit file will erase all partitions first, then write flash data from beginning and if you again stuck at system.img when using pit file, you will be left with a permanent brick. So I will recommend to get it checked by a tech if you want stock rom that bad and don't do any risky thing with your pricey phone

S7 Edge no cellular network

Hi there, I have been using S7 Edge SM-G935F happily and a couple of days back installed the BlackDiamond NFE and was not able to connect to the cellular network or make any calls or use mobile data
Again I tried the OneUI and Pixel Experience and all seem to end up with the same problem.
Inserted the SIM into another mobile and there is no problem with the network or the SIM.
Please help me fix the problem, tell me what do I need to flash/install/update.

I guess you need to reflash the stock rom with Odin.

Thanks for the reply @ariondoneda I will flash the stock rom and will let you know how it went. Cheers

Thanks for the reply @ariondoneda I will flash the stock rom and will let you know how it went. Cheers

So, after downloading various firmware from SamMobile and all versions of Odin, I was able to flash the latest BTU firmware and with Odin v3.14.
The problem is still persistent, the same Three SIM when inserted into another mobile and in the same location gives a signal strength of -63db which is very strong.
But, when inserted back into the freshly flashed S7 Edge hardly gets any signal -113db, which is very weak
I ran out of options and looking forward for some help in getting back those signal bars back in my mobile.
Hoping someone in here knows how to solve this weird issue

Just came across such issue with another guy yesterday.. your efs got corrupted/damaged. You have to fix it either using hardware box (a local repairer shop can do)
Or
Try following this thread to word.. should give you signals back (tested by me) ..
https://forum.xda-developers.com/s7-edge/how-to/fix-imei-downgrading-g935f-fd-t3947911
Note : flashing firmwares again after fixing by above method would negate the fix. Above fix needs to be done after every firmware flash to get signals..

Thanks, @shan22 for pointing me in the direction of a possible solution link
I followed the guide word to word and got a success message from the box and it did reboot like mentioned in the 13th point of the guide
The final result is a no change and still, the same signal strength which is very weak of -113db and most of the times it is emergency calls only

Did you flashed csc or home_csc?
Try flashing dbt firmware (with the same bootloader number as your current firmware and using CSC file (NOT Home_CSC) and then doing a format data in recovery)
Then reflash btu firmware (with CSC file, NOT Home CSC) and do a format. Then retry the fix I mentioned in previous post to word..
Also tell me whats your current bootloader number.. if its less then 7 we can try fixing it via combination rom..

A) Always a CSC and not HOME_CSC.
Try flashing dbt firmware (with the same bootloader number as your current firmware and using CSC file (NOT Home_CSC) and then doing a format data in recovery)
A) Installing the firmware as I write this.
Then reflash btu firmware (with CSC file, NOT Home CSC) and do a format. Then retry the fix I mentioned in previous post to word..

Hi @shan22, thanks for all your replies and time to help me out. Here is what happened. I flashed the DBT firmware which was a success and after the flashing, it started into its default recovery where it said "No command" with a dead droid symbol and died and went into the loop I forcefully started the phone into download mode, installed the TWRP, restarted into TWRP, formatted the data and started the phone into download mode, flashed the BTU firmware which also succeded and went into the same loop of "No Command". This happened a couple of times and none of the DBT or BTU firmware did actually start the system. I had no choice and finally had to install the "PixelExperience_Plus_hero2lte" custom ROM zip from TWRP which worked previously and is working now. All of this effort and it's still down to the same problem, no signal at any time
Sadly, the bootloader version is 8

Yeah version 8 .. no dice. Weird, does your phone gives any error when it gives dead android ?
Looks like you get a dm-verity error upon flashing stock firmware..
Trying flashing no verity zips in twrp after flashing stock rom..
So, your efs is indeed corrupted.
Retry all the procedure..
>flash dbt in odin using csc (not home csc)
>flash twrp in odin and boot into twrp directly without booting into phone
>flash no verity zip, then flash latest magisk zip in twp
>boot into phone
>go in download mode again and flash btu in odin using csc (not home_csc)
>flash twrp in odin and boot into twrp directly without booting phone
>flash no verity and magisk in twrp
>boot into phone and see signals..
If no signals, then from this point refer to my above posts where i gave a link of box like software to fix signals. Follow that thread to word and you should get better signals.

A bit of progress now. As soon as I flash, I need to disconnect the cable from the phone to boot into anything and I am carefully using the auto-reboot option in Odin.
I flashed DBT using CSC, the flashed TWRP and went into it without booting, flashed no verity, then Magisk and boot into the phone. (No errors this time)
Went into download now, flashed BTU, then TWRP and went into it directly without booting. Here when I try to flash the no-verity or the Magisk, I am seeing the error "Failed to mount /data (Invalid Argument)" followed by "Unable to mount storage" error.
Same with Magisk and if I try to wipe the Dalvik Cache or Cache.
The phone is now stuck at the flashing Samsung logo when I start it normally.

You need to format data under wipe options and type yes after booting first time into twrp and then flash no verity zip and then magisk ..
This is a standard root procedure for root on android oreo, I hoped you would know that ..
Do this and re-follow all the steps I mentioned above ..
And please read forums thoroughly before messing with your phones.

Hi @shan22, did the steps you mentioned and passed the /data unable to mount error, followed the instructions of installing the DBT first and then BTU, somehow got the signal but, not strong as the other mobile on the same network shows. I am now doing the steps you provided the link to and will update you. Thanks again for all your help, much appreciated. :good:

You won't get fully normal signals but will get atleast better or almost good signals. Since your factory efs is corrupted, it can only be restored via efs backup and combination rom with matching binary version. Since you don't have efs backup and latest combination roms aren't available, so there isn't a permanent solution for this.

Agreed @shan22 did go through the whole process and there is no betterment in the signal, it's just the same but a bit better than the earlier. I guess I need to look for a combination rom with the same binary:crying:

Sad to hear that, that's why I don't use fully ported/custom roms because they always have a tendency to f*** up your efs, specially if you mess with wrong options or don't know what you're doing.
Even with an efs backup(from when your phone was working correctly), you still need combination rom
And not even paid websites have version 7 and 8 binary combination roms .. the only thing I came across on a lesser known website was that name of version 7 combination rom was : G935FXXU7ATB1 . Maybe it will be of some help to anyone here
