Under your battery you will find a label with your model number on it.

Phone model number changed from N910G to N910F

Hi all,
Been trying out a couple of different custom roms and somewhere along the lines the Model Number of my phone changed from N910G to N910F.
I'm now on the X-Note rom and I am wondering if there is anyway to switch the model number back to N910G? I tried asking on the X-note thread but it was ignored.

Flash a custom ROM that's based on n910g firmware or change model number in build prop it really doesn't matter model number as long as phone works with rom that's y you where ignored because you answered your own question u flashed n910f ROM that's y model number changed
I'm kind of wondering the same thing except I may be more noobish. Lol. I have a sm910t note 4 and I flash the maximum overdrive rom, my model number changed. I just wanna know, if I wanted to change the rom to something else, do I download a rom for what I know my real number is or was? Or do I look for one compatible to this new model number? Sry if it's a stupid question. This rom I'm currently using makes my phone think it's a note 5. I know that's the reason the model number changed, but please, all u android experts, help out bcuz I don't want to destroy my phone. Also since I flashed this rom, there a red text line saying something about kernel. What does that mean?

It will be because the rom you have currently flashed will be based on a firmware from the model it changed to. I currently have a note 7 custom rom on my note 4 n910f. My model has changed to n920f on about phone. If you change your rom again flash one for your original model.
As for the red txt does it say "kernel is not SEandroid enforcing"
Yes it does.

Samsung N910F with N910T bootloader and N910F CSC?! can't upgrade to Lollipop help!!

Hello all I just recently purchased a Galaxy Note 4 and I'm trying to install lollipop via ODIN but it keeps failing I think partly because the bootloader shows up as N910T when the phone model is actually N910F european model that was bought in the UK obviously the phoned has been tampered with in the past and I would like to change the bootloader and baseband which are both N910T to N910F however the CSC shows up as N910FXXU1ANK4 i don't understand this?. Bootloader version is N910TUVU1ANJ7? the phone thinks it is the US T-Mobile Variant im guessing somebody screwed it up in the past? anyhow I need to be able to flash N910F 5.1.1 Lollipop to the phone but it always results in FAIL!(Auth) in Odin v3.0.9 .
Try to flash your stock rom

Try Flashing a stock N910F Kitkat firmware first.
Can you confirm the phone is actually N910F by removing the battery and checking the label?
Of if you are rooted install Samsung Phone Info app from the Google Playstore which might give more insight.

Hi it says n910f under the battery and the phone box says n910f,however Samsung info app says model n910f and bootloader n910t I have flashed 5.01 n910t to the phone and it worked however I have t-mobile bloat ware which I don't want. Is there a way to get everything to be n910f as my UK carrier works on this phone surely it cannot be a US T-mobile variant?

It can be possible, If the device is carrier unlocked the phone still contains some bands which work here in the UK, only Verizon and At&t are less likely to work. My bet is that the previous owner flashed a stock N910F based ROM on-top of a N910T variant. The best you can do is install a de-bloated ROM or remove the apps yourself.

I have the same problem but, I bought the device as new and box sealed everywhere is written 910F and was loaded with N910FXXU1COH4 and I decided to flash the new firmware N910FXXU1COJ3 now I'm stuck at bootloop.
Note: I consider my self a semi-expert but this situation is totally weird.
sorry for necroing this post but i have the same issue with my note 4..
says n910f everywhere (everywhere in the s/w and also on the sticker) but the bootloader is n910t..
all attempts to flash any n910f bootloaders/baseband/stock rom using odin results in emmc write error on aboot.
so is my device a fake n910f ?? (because the sticker says n910f while the phone is n910t bootloader)
or can i switch back to n910f bootloader somehow..

Your phone is masked with n910f but reality is you got n910t t.mobile note 4 and sadly you cannot convert to n910f.
Sticker is faked you have refurbished device.
Its very easy to fake any device even i can do it with root
You will also notice your knox is 0x1 when you go to download mode so it means that someone use root to fake entire device.
Return it now if you bought new with warranty.

Hey Trex, thanks for the reply..
yea it seems like it's a referb but i bought it used for a really good price and everything works with it.
It was such a headache the first day i got it trying to flash anything using odin and nothing worked because i kept downloading and flashing n910f files, I have a lot of experience with rooting/roms but this is the first time i actually didn't know what to do, until hours later when i noticed that in the bootloader it says n910T not F and then everything was good from there.
I won't be returning it as the n910t accepts the same roms as the n910f/g with datafix (i'm using aurora 3.1 for n910f with datafix and it's working perfectly), also the unit i got is like new with 0 scratches and with everything working great so there's that too..

The same thing happened to me 3 days ago, mine was a N910S flashed as a N910F. You're a bit more lucky than i was because the N910T is actually the same snapdragon variant as the N910F. I think the whole hardware parts might be identical. How is the battery life? Any battery drain issue? How much on screen-on-time do you get?

I have n910s also with n910c marshmallow rom and works good
I got screen on time about 4 hours
In my opinion n910s better then n910t/f because n910s/c comes with exynos octa 8core 64 bit processor but sadly no good roms available for n910s but if you use stock it works just good as n910c.
Ram management and games lot smoother and also no heating issues at all unlike snapdragon variants.

The one i had was seriously heating up
If you are using low class micro sdcard and battery that can also cause heating issues cuz apps struggle to run and processor need to run at higest frequency.
Do factory reset and try phone without micro sdcard and use for 1 or 2 days
And try another battery if you can.

Your device is n910t and faked with n910f.
Download link for latest marshmallow firmware below
https://www.androidfilehost.com/?fid=385035244224395816
Extract and Flash this firmware using odin.
It will not sim lock your device but your phone will be completely n910t and there will be no many languages.i suggest if lollipop is working fine with you then don't update.there is nothing new in marshmallow and it will make your device slower then lollipop.
Thanks a lot tex888 ,,so what i understand the only bootloader that i can install is the Tvariant.
If i nstall a custom recovery can i install a custom rom fr language without problem.
if no i will keep my 5.0.1 with french language

Help identifying my device. I purchased a used Galaxy note 3, n9005,n900t,n900a

I purchased a used galaxy note 3 from ebay. It came running n900tuvufob6 lollipop, when i do and imei check the imei# comes back as a n9005. The device it self has an at&t battery cover and the sticker under the battery states its a n900a??? i need help identifying the device. i just recently flashed darklord n5 rom with twrp and would like to try some other roms out there. So what device do i actually have, a n9005, n900t, or n900a. Any help would be appreciated.
Your answer lies in the baseband. It's most likely a N900T.
confused

Install Stock T-Mob firmware on SM-G900V

I was given a branded Verizon Samsung Galaxy S-5 running Android 6.0.1
The Config Version is J13SAMSMG900V.1
Build Number is MMB29M.G900VVRU2DPF4
Kernal Version is 3.4.0 [email protected] #1
Baseband Version is G900VVRU2DPF4
I want to replace the Verizon build with a T-Mob, with all the functionality. Is this possible?
Will T-Mob look at it as a T-Mob branded phone (receiving updates and such)?
Will the Play Store work properly with the updates?
Will Android Pay work (or other NFC oriented pay apps)?
I am new to trying this, so the simpler the better.
Thanks.
It is possible to have a t-mobile system Img installed all this does is allow you to flash a g900t aosp based rom onto your device doing this is extremely buggy no data calling or texting is the common result of doing this
as for an Ota update it would more than likely hardbrick your device if you had a g900t system Img installed on a g900v
but to answer your question no it is not possible bootloaders are g900v still so you cant get g900t firmwares installed and if you try to change your bootloaders you will hardbrick permanently with no way to recover
It is not worth it a few people claim to have changed a g900v into a g900t but they don't provide a guide or files so they are lying
Don't believe them
I tried changing a g900v into a g900t and made a rookie mistake I was partially sucessfull one or 2 boot loaders changed but not all 3 trying to unlock a g900t bootloader with a g900v method and got a hardbrick waiting for a debrick img to be made
If I get it debricked I will try a g900f conversion instead of a g900t conversion

Identical to jrhack. I already had a T-Mobile account, and don't want a Vz, but I overlooked learning that it was a Vz phone when I agreed to buy it. At this time it still has the Vz firmware, software, apps. I would like to debloat it and root it.
So far, on the T-Mobile network, it works fine, except at times sending an MMS will fail, but not always.
I would appreciate your recommendations. There is no warranty or service provider involved here. Just me and the phone.
Thanks in advance.
To get root downgrade to lolipop ok3 or pb1 firmwares and use Jr Kruse ok3 root method on xda under s5 Verizon section and then debloat stock firmware and a good close to stock rooted debloated rom is jrkruses PB1 deodexed rooted deknoxed debloated rom

I have a verizon s5 with a cid15 so i can unlock the bootloader.. My thing is. Is there any possibilities of changing the baseband to any other baseband and ultimately getting that over to the tmobile baseband? Kindof like on the S7 edge where you can flash the U firmware and change the baseband.. Would we have any luck on anything with this phone ultimately being able to change that phone over completely? Just wishful thinking on my part.. hah
