Make sure you have an ATT APN and the correct network mode selected, LTE/GSM/WCDMA

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!!

[Q] Samsung Galaxy Note 4 network mode

Hello all,
I am using the exynos variant of Galaxy Note 4 and using the official lollipop firmware.
But when I went into setting to choose network mode then I only find 3G and lte options. No GSM/WCDMA options there. Is this normal or is there something wrong?
Link to the screenshot so that it may be clear as to what I mean

hi ,
ok .i do not have the exynos variant ,but N910f Snapdragon .I have Lollipop ..BOC5 running on device .
However i do not think above issue , would make much of a diffs ,as its "software related issue" ?
Check my screenshot for difference to yours ( all my devices ,no matter what Rom i was using eg German ,UK etc always reflects the same .)
Maybe look a bit wider eg ..Carrier software ..etc
But i find it very strange you have no other network options ?
good luck

Thank you for the response. Even I have never witnessed anything such as this in any android mobile which I have used. Maybe someone with Exynos variant would be able to confirm this thing.

910K is a Koreean version. It seems that the software is how to put it...branded, and the gsm/edge options are not available, as the carrier that sels the variant of phone does not use those frequencies... I can't figure out any other explanation. Maybe flashing a different variant of lollipop would help, but I am not shure if the LP variant from the international version of 910C is compattible with 910K. I will do a search if my time allows it and get back to you. Cheers!

Factory unlocked...as in you can use any sim card from any carrier. The problem here is your ROM...that comes with a little extra "features" implemented In your case it is a branded software by KT Corporation / Koreea Telekom

Hi, was unable to do the mentioned steps yesterday. Would try today for sure. Will pm you once done.

I can assist you to Reflash the device to the stock international variant, not sure if it will kill the unlock or not, but would assume it won't

Unlocked G900P Sprint for Int. but no Data

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.

Unlock extras LTE Bands

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.

Idoneapss.

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.

Lost LTE after PIE

Hello guys.
I have an issue since I decided to flash a pie rom, specifically simplix blue, have no idea if has something to do with that rom.
I used to have LTE as normal and everything was good. Since I flashed a PIE rom I lost LTE. I tried going back to stock and LTE is still gone. Had tried flashing some modems, did not work either. Tried several radio combinations on *#*#4636#*#* did not work.
Any suggestions? I am on Tigo Colombia as carrier and never had this issue before across several xiaomi devices that I have had

I have seen several people here with similar issues and not being able yo Solve it. Hopefully the tutorial that I Will make, help them as well.

Yep, I have been quite busy, as soon as I have time, I will post a tutorial. Meanwhile, take a look at this post, read first part of post 3 and then post 7.
https://forum.xda-developers.com/lenovo-p2/how-to/enabled-4g-ca-p2-t3707584
As soon as you finish adding the band, install network signal guru, provide root admin rights and then select on the 3 dots at the top right corner lock bands, select lte and pick up the band missing and reboot.

Also facing this, I'm waiting for tutorial.
