Hey there folks
I have a SM-g900t that i got off Ebay (unlocked, KNOX counter Tripped). i got it because i hated my SM-G386W.
so i get this S% and start playing with Custom Roms and Loaded a rom from the SM-G900F ("ViSiON-X" or some crap) and while it works good, i cant connect to 4G anymore. phone cycles between HSPA, HSPA+ and 3G.
since im on Wind Mobile (inb4 Wind doesnt have 4G, they do, in specific areas, such as mine) i thought i'd flash the phone with the SM-g900w8 firmware from Wind mobile.
when i tried i got a Secure Check Fail: aboot message on the phone, and odin just immediatly fails.
im obviously doing something wrong here, and im guessing its going to be simple as hell to someone whos more experienced than i, so i thought i'd come ask here:
(TLDR here) How do i get my SM-G900t (that thinks its a SM-G900F at the moment) to think its a SM-G900W8 without getting "Secure check fail" messages?
before anyone asks: That samsung re-register thing is off.
to me it sounds like your phone settings are not on lte/gsm or lte/wdcma/gsm if your talking about additional 4g lte bands you could folloe this guide by fffft http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
P.s DONE NOT FLASH SM-g900w8 firmware on tmobile variant you WILL BRICK. plus it wouldnt solve your problem.

Hey,
I ordered and received a N9005 unlocked version. I am on Bell network in a city where they use AWS (aka Band 4, aka 1700/2100) and (this is my bad for not checking carefully before ordering) this version doesn't support those LTE bands. It obviously connects fine through hspa+ though.
So, I was wondering, since the hardware actually supports those bands, is it something that a hack could unlock in the future (be able to use LTE with this phone on this network), or am I just gonna have to live on hspa+?
I purposely put this in general as I believe the discussion that this could drive would make it more fitting than in the questions forum if this is a possibility.
Thanks,

LTE compatibility has been discussed in so many threads, you really should do a search before posting next time. If your phone has unlocked bootloader just flash Bell's modem onto it, once it becomes available. Or ask a friend, who has Bell branded GN3 to dump the radio for you, and take the firmware from him. Qualcomm's MSM8974 chip does support all LTE bands worldwide: http://www.qualcomm.com/snapdragon/processors/800

I usually do make a search but through all the threads relating to various questions regarding model variations and other questions relating to LTE, bands, compatibility, my search rendered very little insight to my specific question (although I'm sure it was answered before as you say, I just wasn't able to find it through all the other stuff relating to my keywords). And as you can see from the answer above you, I wasn't able to trust some answers that I managed to find.
Truly appreciate your answer though, Thank you very much and I'm happy to know I'll get LTE again soon.
Thanks
I too am waiting for a modem with 700/1700/2100/2600 on the LTE side. For the Note II this was done using Qualcomm's software to instruct it to use those bands... Rogers, Telus and Bell are all launching tomorrow on October 4th - sometime after then I hope to see the modem online and give it a whirl, but I suspect we might need a QCN file change also.
There is hope!
Got us a little closer: On my N9005 - *#0808# will bring up the Qualcomm USB settings.
On the Note II and S3 this is usually *#7283#
We're getting closer! Those with N900S / N900A / N900W8 phones, feel free to dump your NV Params QCN file now using the Qualcomm QPST Software!
bump!
No real luck yet. I can't flash N900W8 firmware onto my N9005. Neither the whole firmware or just the modem.bin.
Editing the NVParams didn't really work either, as some we tried just get reset to default after a reboot.
I flashed a N9005W8 modem (using dd as root) and unfortunately, it fails to communicate. Baseband shows as unknown. I suspect only a NVRAM dump with removed imei will work. Otherwise modem will need to be ported properly.

bump.... looking to find out how i can pull the modem file out of a specific firmware file, such as pulling the modem file only out of the bell tar file and then making it flashable with odin for my wind phone? i am downloading the whole bell firmware right now and am going to try to flash it on my phone..... i already tried the puerto rico one and it works, but with bell i only get hspa i assume that the bands bell uses are different than the PR ones. i do know that someone has already stated that they got rogers bands with it, but not bell yet, i dont think....

What does that bin contain? Your sayin that is necessary when i flash the modem? When i flash other n9005 modems i dont flash it.
In either case i dont have a copy. Upload and ill try.

Download the entire N900W8 firmware for odin. The modem and many other interesting things are within.
However unless you know something i dont, you will soft brick your phone. Assuming you are able to flash at all. (odin will not reject the rom)

Do you think in the future they will extract just the modem and I will be able to flash that separately? On the S3 I remember being able to flash different modems with the latest CWM.
Right now I have an unlocked n9005 with the Baseband I quoted in my last post. I am using it fine on Rogers Canada lte but in some places the signal is weak and I will lose connection altogether. I was hoping flashing the modem for my provider and region might fix it since the s800 has the correct frequencys for Rogers I think some are disabled or not being used because of software (it was an Asian model I think with a csc for a different region). To reiterate it does work on Rogers I was just hoping I could fix these network drops by flashing a more appropriate modem.

The modem is simple to extract, just untar the odin package.
The trick is actually making the modem boot.
The PBL appears to reject the modem, and thats very bad news for this concept.

bump, is this possible yet?
Just thinking out loud here, but I wonder if flashing the Canadian csc file would be helpful here? In the stainless rom thread in t mobile the op has the Canadian csc file posted. I wonder if flashing that first would allow things to boot with the w8 modem?
I did some thinking, and since you are trying to get a band working that the Snapdragon does support natively, maybe there is a chance. I would hazard a guess here, after some research and guessing, that the antenna actually would work here, so it could, in theory, just be a matter of firmware. Unfortunately the stock modem for the n900w8 may have to be modified to work....Not sure there. But may be an idea to flash the Canadian csc then flash the modem and see where that gets you? Not responsible if your phone bricks cuz I have no idea if this could work, as I said, just thinking out loud
Any updates on this? I too am interested in getting LTE on my n9005.

Yes I have cause I had net 10 before and It worked 4g lte .I had changed because most people said that ATT is the quickest network and probably is but you have to use their own machines.they said,... I flashed original stock tar to start it fresh to see if there was some trouble when I flashe custom roms I will use triangle apk app to reset counter to 0 and start it over once I root again my machine. I will keep in contact thanks!!

Hi!,
I have a SM-G900V from Verizon and everything looks ok except that I cannot get an LTE signal. The tech from my local carrier (Smart PH) said that the LTE Freq is ok but the SM-G900V is on bandwidth 2 and it needs to be on bandwidth 1. I checked the local S5's here and it has SM-G900F on them.
Can I download an SM-G900F from anywhere and flash it on my SM-G900V? Will there be problems?
Thanks!!!!

If you try to flash a G900F official ROM with ODIN, it will not allow it since it will recognize the model difference.
Rooting your phone, installing a custom recovery and flashing a G900F ROM this way (not an official ROM ) is probably the only way.
HOWEVER, although they are probably identical hardware-wise, there is an extremely high risk that you will damage the device.
the 900F supports the following bands:
LTE 800 / 850 / 900 / 1800 / 1900 / 2100 / 2600 - SM-G900F
the 900V supports :
LTE 700 MHz Class 13 / 1700 / 2100 - SM-G900V
which are different bands, not sure just rooting and trying to flash an F modem to the V will do but i believe that it will be EXTREMELY risky
Nah RISK is a word I tend to stay away from when it comes to rooting. Paired with "EXTREMELY HIGH" maked me want to drop it. Just swapped my S5 with a Note 3 my wife uses... Now I have a very Pink Phone

Hey bro After try to flash g900v convert to g900f what happen success or hard brick
Hey, guys.
Thanks for reading.
I bought a locked S5 G900P from Sprint (BOD3) but I live in Brazil.
After a few days reading threads, I've finally managed to downgrade it via CWM (installing stock NK4 kernel and SM-G900P_NI3_ROOTED_ODEXED).
Then, I've unlocked it via SSU. Since I couldn't get any data, I tried a lot of workarounds (installing shohat rom, cm11...) but nothing. Then, I decided to flash the latest firmware available at sammobile: G900PVPU3BOF6.
No data from the latest firmware also.
Now, my phone is back to ShoHat V5 Rom (4.4.2), with G900PVPU3BOF6 baseband and NK4 kernel.
The signal icon on the top of the screen appears to be full (four bars) and I can see the phone carriers, but I can't register to mine (VIVO Brasil).
Does anyone know what I'm supposed to do? That's the configuration that got me closest to receiving data.
Please, any help would be greatly appreciated.
Again, thank you for your time.
Just saw that on my phone, despite using SSU:
NETWORK. BLOCKED
IMEI CERTI: FAIL, -9
Any help? Please.
Your network bands do not match the phone bands.
Go into the secret menu. Try downloading Phone Info app for this.
To unlock all the bands try this. Go to UE Settings/Settings/Protocol/NAS/Network Control/Band Selection and select LTE all bands.

My IMEI is locked and it's illegal to unlock it in Brazil. I'm about to try to sell this goddamn phone.
I am currently running a G900A (AT&T branded phone with locked bootloader) i am in the process of buying a used S5 but not sure if the bootloader is locked. Here is the phone info that the guy provided to me.
Sm-g900f , g900fxxu1anc9 , 4.4.2
Like i said in on AT&T S5 so i am not familiar with the F models. Any info would be much appreciated.
Is it rootable through towel root? Can i use TWRP or CWM south this device. It is carrier unlocked and he is using it on T mobile (gsm) so I'm guessing it will work on AT&T since is uses GSM as well. Thanks for any help.
