Hello guys and girls. I successfully unlocked the bootloader of my SM-G900V and now I'm on the most smooth CM ever.
I live in Brazil, and here we don't have the LTE bands that the Verizon's S5 uses. So I tried unlock additional bands using this thread: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059.
Guess what? Didn't work.
It occurred to me that the problem could be the modem firmware, so I tried to flash modem from the others variants, and.... nope. ODIN's flash fail, and the download mode screen says "SECURE CHECK FAIL: modem" (something like that).
I almost made an attempt to flash using dd, or recovery, but decided to ask first.
Honestly it's hard to find a flashable zip of any version of modem.
I already made a backup of modem partition, in case of anything goes wrong.
The only LTE band I need is the 7.
My questions are:
Does anyone tried this before?
What is the risk to flash a modem firmware from other variant using dd/recovery?

Unfortunately it will not work. I've already tried before unlocking the bootloader. I'm now on CM13, and they does not have a hidden menu, only stock firmware (or port). Plus, when I accessed the menu on stock firmware, the B7 option said something like "not supported". Probably because the software is modified by Verizon.

Some clarification: Galaxy Tools by Idoneapps is a tool for changing various APN and hidden settings on the S5. I couldn't find an official link, but I have a direct link to the AndroidFileHost download. https://www.androidfilehost.com/?fid=24052804347804710
You can probably find the band and APN settings yourself easily enough, but I'll do some experimenting and update when I find the options. It isn't the easiest UI.

This is the working links off apk file . You can play with , try different settings and remember if something not working wright always restore to initial settings . Good luck !
Yesterday I tried to flash modem.bin and NON-HLOS.bin from another device using "dd". The flash was ok, and the device did turn on without problems.
I tried the baseband of these three devices: SM-G900M, SM-G900P and SM-G900T.
But... no LTE for me.
I'm still looking for a way to do this.
I have the Verizon varient and was able to set the APN to exactly to what my unlocked moto x pure is. It works perfect with at&t.........so far. I guess it's all about the APN since the sim is unlocked.

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.
OK, I just come across an S4 SGH-i337M running 5.0.1 locked to Bell. Searching Google is fairly mind boggling as everyone has their own method. In my situation, I'm pretty sure I have come to this solid conclusion. Two options only,,
1. Buy unlock code or
2. Downgrade to at least 4.4.2 and use the hidden codes method.
Can #2 be done safely? Some sites say if you do try downgrade from Lollipop to KK, it will brick. What would a safe procedure be if possible.
Thanks

Thanks, seen this but wasn't sure. I assume that flashing back to Lollipop isn't necessary if one chooses to stay at 4.4.2 for a while. Heard some comments about increased battery drainage etc. on Lollipop.
Will try this once the new charge port shows up and I can replace.
The hidden codes method won't work, unfortunately. Let me know if you are successful.
Thanks.

Thanks, will do. Hopefully will be getting to it tonight. Here's one of the confusing things I was talking about. Been doing alot of reading, and in your instructions, you install TWRP to flash SuperSU and such. Then, reading elsewhere, I see this "SAFESTRAP IS THE ONLY RECOVERY WE CAN USE!
Don't even try flashing another one.", posted in a thread about AT&T SGH-I337 model. Well, here it is, halfway down in the second post, bolded in red. http://forum.xda-developers.com/showthread.php?t=2616221 Just trying to get things figured out, it's been a couple years since I last played with the Galaxy, just getting back into it now.
The AT&T version of the s4 is the Sgh-i337 and, if it was running stock 5.01, the bootloader would be locked and twrp cannot be used.
The Canadian version of the s4 has the letter "m" at the end of the model number and the bootloader is not locked which allows the installation of twrp and custom ROMs that are not based on a tw kernel.

Thanks, this method seemed to work,,just one problem I overlooked, but I just assumed this phone would work on AWS1700,,wrong lol. I was reading the 141 page thread and there seems to be a few different methods for doing this. With my S3, I only had to flash the NV and run a script on every boot as the nv rewrite would not stick. Is this so as well with the s4 too,,or is there a method to make it a permanent stay. I didn't plan on updating to 5.0.1 quite yet,,but will do if needed. Do you no of a recommended/preferred method for this?
Did you test the phone with another sim card? Hopefully, you will not be prompted to enter a network unlock code.
For AWS, I'm not sure what needs to be done as I am using a Telus s4 on Bell.

It was locked with Bell, my provider is Eastlink,,I finally got the AWS1700 band working, but kept losing it when the phone went to sleep. Updated to the NE1 modem, then had to flash the AWS again and all seems to be working fine. Hopefully it holds up. Thanks for everything.
Glad it is all working. We're all here to help and learn from each other.
Hi everyone, I just wanted to know if is possible to use the SM-G935A model in Europe? I know that USA models are using differend network frequencies so I was not sure...
Also how can I check and know for sure if the phone is carrier locked, and if it is, is there any way to unlock it here in Bosnia?
Should be fine but check what frequencies your network uses and then compare

It supports Band 3, 7 and 20, commonly used for LTE in the UK and Europe.
It also supports both 2G and 3G on all networks in Bosnia.
Since all countries in the EU use the same LTE bands, it'll work everywhere.
Thank you both for the replies.
Which site is recomended for carrier unlock, I have found cellularunlocker (dot)net but I am not sure if it is reliable and safe to use? It costs 25$
I am sorry if this is not allowed to ask on the forums.

Hello, thank you very much. I will try it and I am familiar with flashing roms, so I will use ODIN to flash a stock ROM which is rebranded. But could you be a little more specific about the partition file, as where I can find them and how to flash it?
Is there a risk of bricking the phone?

Don't know if there are any, but you'll have to find the newest SM-G935A ROM with a PIT file, apparently that removes the network lock.
If you're still hesitant to flash, you'll have to find a reputable cell phone unlock code website. Not sure about them since I've never needed to use one.

Using Odin 3.12 and latest 930T firmware
I can flash older stock firmware which makes me think it's not the bootloader?? I've done this exact conversion a couple times in the past on other phones without any problems at all.
Error Message Fused 5 Binary 4 .
Phone is officially unlocked and will allow calls with the T-Mobile sim, but won't allow LTE/ Data due to the bands being locked.

Your second post, but at least wait a day... And this has been covered numerous times.
Your binary 5 issue means that you can only odin current firmware for the sprint version.
You may be able to odin the latest sprint firmware, install the u modem, and that may unlock your bands.
But basically, you are stuck with sprint firmware until the others catch up

Check the last 5 digits of the firmware. It should have a 4 or 5. Your error message states that it has the newer bootloader.
On the train now, but you could go back between binary 2 and 4 with a pit file. Search this forum or the sprint s7 edge one.

My 930T modem on the phone (the one I flashed) starts with a 4... build number on the phone is 930P and last 5 starts with a 5... again I really appreciate it! I'd read there was no way to know which bootloader was installed via a code on the phone. I hadn't found any info on bootloader release dates so I was working backwards installing firmware
I'll read up on the pit file also!

Check out this thread
My phone is on the U firmware, but I remember using this method about a year ago. You can try to ODIN the PE1 firmware with the PIT file. It let you go from b4 to b2, not sure if it will work for b5 to b2...in theory it should, but you who knows. The most important part is adding that pit file.
So you install PE1, then you can install the U firmware
Worst case scenario is that you probably just have to reinstall the firmware you have now.
Please let me know if this ends up working.
Flashed newest 930P firmware and switched out with newest 930U modem... bands still locked. Everything uploaded smooth through Odin, just no change in service... messed around with VPN settings a bit and tried a 4g app.. still no data. Haven't tried a pit file yet

Tried it both ways with and without.
I'll try to mess around with the bands tonight via your link. I appreciate it... prior to this bootloader even the bands weren't an issue for me... I've spent way more time on this phone than it's worth lol. The old man I bought it from spent over $800 leasing this thing. Frustrating that Sprint thinks they can stop him from switching carriers now that the phone is his.
Had some time... I enabled band 17 (it wasn't before).... still no LTE. I've gotta find which bands are needed in my area I guess. I have access to all of them via the thread tutorial you posted. ... feels like I'm almost there!
I don't think it's the bands that are the issue. All the bands I need are checked/unlocked already. From reading I don't get the impression that there is a best "in my area" band. ALL the LTE bands listed on T Mobile's site were already unlocked in the phone. ??
