[AT&T Samsung Galaxy Note 4] tbong777:
This thread is for those who bought T mobile 910Ts and are using them on ATT with working LTE and Custom Recovery. I thought t would be nice to have a centralized thread for non ATT devices being used on the ATT Carrier

Any issues, Rom Comments, should be posted as well. Include your phone and ROM in your Sig,

I received my T Mobile 910T from a seller at Swappa.com It was rooted and Rommed with FireKat V4 (I have since flashed V5) and see no reason to switch Roms.

However, The phone I received was not unlocked. I used cellunlocker.net for the code and it worked perfectly

allowing me to use my four year old ATT SIM from my N7100 Note 2 (even though the Costco Cellular Kiosk gave me a new SIM card free before my phone came)

I called AT&T and gave them the IMEI and they provisioned me for LTE even though the phone shows up as a flip phone on their site. . LTE is weak around here but the phone does indicate LTE when it's available. I paid $700 for the phone . There are less expensive ones available for those who don;t want to deal with T Mobile and a 40 day plan.

The phone uses TWRP or PHILZ Recovery and flashing roms is no different than it has been since the first ODIN version was used to flash a recovery TAR file. I prefer TWRP

I have no confidence in developers finding a way around the ATT bootloader lock nor the incentive to make it work like an international device anytime soon if ever. The only alternative for me was to get a developer Note 4 with Verizon. My wife runs an ATT S5 and does not need root so switching carriers would have been a non starter since we both are able to use 4G LTE

ANOTHER Version of information regarding bands.

T-Mobile

Quad Band GSM; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850); LTE: 1, 2, 3, 4, 5, 7, 8, 12, 17

AT&T

4G-LTE Bands 1, 2, 3, 4, 5, 7, 12, 17, 20, 29

3G - UMTS 850/1900/2100MHz

GSM/GPRS/EDGE 850/900/1800/1900MHz

so what are bands 20 and 29? they're bands for carrier aggregation in the US and not international support.

I would not get too hung up on "compatibility" at this point. Many of us users are enjoying their 910T on AT&T without issue.

FROM Xda Member MIRCURY re Note 3 T mobile use on AT&T Much of the same applies

RE TMOBILE NOTE 3 ON ATT (Changing Note 3 to Note 4)

Much of the same applies

This is for people who have AT&T Service and are looking at the T-Mobile US Note 4 (N910T).

Why are people wanting to use a T-Mobile Note 4 on AT&T?

Because AT&T, much like Verizon, has tried to lock down their phones making it very difficult to use custom ROM's or apps that require root. AT&T and Tmobile's networks are similar. The N910T (Tmobile Note 4) is bootloader unlocked.

What does carrier/SIM locked mean? Is it the same as bootloader locked?

. US phones that operate on GSM networks require a SIM card. The carriers don't want you taking your phone to another carrier without fulfilling your contract so they lock your phone to themselves and the SIM cards they offer. Once you fulfill your contract or pay for the phone in full they should be willing to issue you an unlock code. Some carriers like T-mobile make you wait 40 days after you buy the device to unlock it. SIM unlocking the phone will allow you to put a SIM card from another carrier in the phone.

How can I carrier/SIM unlock my T-mobile Note 3 if T-mobile won't?

Several people have used cellunlocker.net including me. Select U.S.A. T-Mobile and N910T as your device. This also removes any region lock.

Will LTE work on AT&T?

Many people have confirmed that LTE works. There is no speed difference between an AT&T branded phone and the Note 4. Documents obtained from the FCC and also on T-Mobile's site say it supports the frequencies used by AT&T.

What APN settings will my Note 4 need for AT&T and MVNO's?

Root, custom recoveries, roms, and kernels for the T-mobile US Note 4

The T-Mobile Note 4 has a dev community that is growing rapidly. You have plenty of options to customize just about everything available on your Note 4 You can flash roms and kernels that give you extended run time and overclocking. We can even cut out the carriers and flash international roms with some modifications so we can have the latest and greatest directly from Samsung. Using custom recoveries such as TWRP will trip the KNOX counter.

For TWRP recovery is the recommended recovery for the N910T and is the first step to flashing roms and kernels.

TWRP 2.8.x.x TeamWin Recovery Project is available here http://teamw.in/project/twrp2

For CWM recovery use this.

The first step is to flash a CWM recovery . After that you can flash a pre-rooted ROM that is compatible with the N910T or flash SuperSU here.
