1. You can flash cm12. 1 on top of jelly bean or Kitkat.

2. Yes

3. You can use AT&T sim if your device is unlocked, use search to find out if you'll get LTE or not.

4. I use twrp and have no issues with it.
[T-Mobile Samsung Galaxy S 4] Frankenscript:
When using ATT SIM on T-Mobile device, be sure to go into network settings band set the APN to the ATT settings. Works great; I'm using ATT service on my M919 right now. I have a thread around here documenting my experiences.

Can I use the screen of I9500 in M919?
[T-Mobile Samsung Galaxy S 4] _Spectrum:
Just read your thread. It seems really detailed and informative! Just one question. Once your got your T-Mobile s4, did you have to contact AT&T that you are switching IMEIs from a previous android LTE device?
[T-Mobile Samsung Galaxy S 4] Frankenscript:
No need to tell ATT. I just popped in the SIM, adjusted the APN, and everything just worked fine.

I eventually did go to the ATT store at one point months later on unrelated business, and had them update their system with my IMEI (I was troubleshooting something else, that turned out to be user error). No reason not to give them the information when it is convenient for you to do so, but there's no requirement to do so.

Good luck with your M919!

Anyone know the answer to this question?
[T-Mobile Samsung Galaxy S 4] a103:
Check the s5 thread for the answer for first question. If you're referring to s/w update it's still on Kitkat 4.4.4, baseband nk2.
[T-Mobile Samsung Galaxy S 4] awdark:
That's actually really reassuring. I was beginning to think everything revolves around download mode and odin.

From the other replies it looks like we don't really need to worry about the locked bootloader or knox with the CM roms. I'm slightly concerned about flashing different versions that might conflict with each other. In particular if I went from stock to cm back to a different newer stock. Sounds like knox can cause quite some issues with wifi and connections. And I don't know how different roms will behave with the different baseband or bootloader. Although it sounds like those are bundled occasionally.

I guess I just have that idea like for the PSP 1.5 was king and everything revolved around that old version. Or the xbox 360 you can potentially run unsigned code if you didn't update past a certain point.

From what I searched; back in 2014 user with att s4 boot loader was locked thus can't install TWRP, non touchwiz roms, modems or kernels. That's what worries me and I want to keep those options open. Tripping knox is fine warranty expired already.

Stupid question time. When we flash the rom it will wipe then load correct? It won't just merge and overwrite files of the same name.

I messed with files with root access and hope those changes will be removed.
[T-Mobile Samsung Galaxy S 4] preacherjoe123:
If you flash a new ROM then your root folders will most likely be reset to the specifications of the new Rom. You wipe first then flash. Wiping the phone helps lessen conflict between previous ROM files and new ones and will remove unnecessary system files.

Do I have to wipe in Recovery before flashing in Odin?

Hey everyone, I have a small detail but very important thing I need clarified. I am running CM11 on my SGH-M919 and it's really buggy and I'm sick of it. After experimenting with a few different ROMs, I've decided this headache needs to end so I decided just to go back to stock. I found a stock ROM at http://MrCrab.Net(I realize that this doesn't look that trustworthy but I went to SamMobile and got a Bad Gateway after choosing a ROM) and I'm almost ready to go​

My one question is before I flash this .tar.md5 in Odin, do I have to wipe in recovery? It is not specified in, http://www.droidviews.com/but I heard that if you don't wipe before you flash a new ROM you can brick your phone which is exactly what I don't need.​

If I do need to wipe, do I need to Wipe, or Format? I believe the difference is that a format clears your ROM of your phone, but does Odin take care of that for you? Am I missing something important? Any help is appreciated, thanks​
[T-Mobile Samsung Galaxy S 4] a103:
You don't have to wipe anything, just make sure that you enter the download mode using the power+volume down key combination. Do not use the restart menu on ROM to enter download mode.

Odin will take care of wiping everything for you.
[T-Mobile Samsung Galaxy S 4] kayits:
Haha! No, i ask before.

Hey guys. I posted this question before but I got no answer . I have a galaxy s4 tmobile and the data keeps turning on by it self even when i shut it several times. Also when the phone restarts or reboots it automatically turn 4g on. This is after I rooted my phone with 4.3.

[T-Mobile Samsung Galaxy S 4] lalec:
If you are trying to control data usage, an easy way to do so would be to install AFWall+ and restrict mobile data on everything. Once you get it set up you can disable or reactivate it in a matter of seconds.

Knox does not cause any problems on the M919, correct? I want to flash stock NK2 (bootloader, modem, everything; I'm currently on MDL with CM12.1) then go back to my CM12.1 ROM; but want to make sure it won't affect anything at all. The only thing Knox does on this device is for warranty purposes, correct? (which has ended a long time ago)

Lost my IMEI with "Erases All EFS1/2/3!"

I lost my IMEI by following an ill-advised guide that had me go through "Erases All EFS1/2/3!".

I did not create any backup and after flashing a stock ROM, my IMEI on the phone shown via *#06# in the dialer is now "/ 08".

I've searched and searched for a working solution all over the internet for the last 5 hours and I am now completely lost, angry, confused, and in complete despair.

I am only a novice in dealing with any of this and it's taken me a while just to be able to properly flash a stock rom with Odin.

If there is a kind & talented soul here who can pull me out of this wretched hole of anger and despair, I'd be forever grateful to you.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Unfortunately the process you need to use to fix your phone cannot be discussed on XDA as that process is used to make bricked stolen phones active again. As such XDA does not allow the dissemination of this info.

Restoring your EFS backup would have worked. Unfortunately you don't have one.

The good news is that your phone is not dead. It can be fixed. There are people who provide this service who can be found on places like Craigslist (if you are in the USA) or similar sites globally.

They tend to be doing this illegally..so be careful.

[T-Mobile Samsung Galaxy S 4] Frankenscript:
Verizon version has different antennas than T-Mobile. Verizon works as a cdma device which is different from and incompatible with the T-Mobile gsm system. Sorry.

[T-Mobile Samsung Galaxy S 4] ShinySide:
Normally yes, you're correct. In the case of the s4 and newer devices, they're actually GSM devices. Same with sprint devices. You can actually unlock them and bring them to tmo/MetroPCS. I know people running both sprint and Verizon iPhone 5's on MetroPCS which is now gsm/on tmo's service.
[T-Mobile Samsung Galaxy S 4] Frankenscript:
Congratulations on getting it to work. I was a bit surprised so I dug deeper. I found the specs on the VZ/Sprint version:

LTE 4 / 13

WCDMA 1 / 2 / 5

CDMA 850 / 1900

GSM 850 / 900 / 1800 / 1900

Sprint version supports CDMA 800 (BC10) & LTE 1900 (band 25) instead of LTE 750/1700 & WCDMA 850 / L720T variant supports tri-band LTE ("Spark") for Sprint​

Indeed it does have a GSM radio and two LTE bands. My apologies for my prior inaccurate remarks. I looked up what was needed for T-Mobile (as carriers use multiple bands) and found this over on AndroidForums:

To summarize, here are the specs you should be looking for when you're trying to determine if a phone will work on T-Mobile's network:

GSM: 1900MHz

UMTS: 1900MHz or 1700/2100MHz

HSPA and HSPA+: Designates phone is capable of faster speeds on UMTS frequencies

LTE: 1700/2100MHz (also designated as LTE Band 4 or Band IV)

The only specification a phone must have is GSM 1900MHz. If a phone has, for example, GMS 1900MHz and UMTS 1900MHz, then it will still work, but the data will be slower than a phone that is HSPA+ capable, and it will not be able to use the LTE network.​

But T-Mobile is re-farming it's frequencies, so you may eventually not get LTE in all areas. I found this :

It's complicated. T-Mobile currently primarily used band 4 (AWS, 1700, 1700/2100) for LTE. In the near future they will be adding band 2 (1900, PCS) LTE in some markets. They will also be adding band 12 (700 A) in some markets. Band 12 is not the same as band 17 (700) that is supported by some AT&T phones.

T-Mobile also uses band 4 for HSPA+ with additional HSPA+ on band 2 in many markets. I believe the current plan is to migrate most HSPA+ to band 2, probably combining it with GSM in a single 5x5 RF slice. Most everything else will be refarmed to LTE (eventually).

Bottom line, for optimal utility a T-Mobile phone needs to be:

1. Quad-band GSM

2. HSPA+ on at least band 2, band 4 & band 1 (2100) for roaming.

3. LTE on bands 1, 2, 4 & 12.
​

Your phone is only band 4 + 13 LTE apparently, which covers many areas T-Mobile serves at the moment, but eventually to get LTE everywhere, you would also need bands 1, 2, and 12.

I hope this is helpful, but for now it looks like you're good. I think Verizon has a locked bootloader, which limits what you can do ROM wise. I had an ATT S4 for a while, which was also locked bootloader, and had to use SafeStrap which meant only Touchwiz ROMs would work. I sold that ATT S4 and bought a T-Mobile S4, which works great on ATT and also comes with an unlocked bootloader, so I could run AOSP ROMS.

I've been out of the "bootloader controversy" for a while so perhaps it is no longer relevant.

I believe all the phones can be rooted with TowelRoot but check in the Verizon S4 thread for details. I'm not an expert on that variety by any means!!

[T-Mobile Samsung Galaxy S 4] a103:
Yes you can install S4 I9505 TouchWiz Lollipop ROM. You can even install Google Play Edition Lollipop ROM as well. You can find those ROMs in I9505 Android development section. I will not suggest which ROM you should use but there are quite a few options to choose from. You can also install CyanogenMod ROM. All the best and happy flashing.

However, you will lose WiFi Calling/WiFi texting if you go with a non-TMO ROM. Other than that, you should be fine.

[T-Mobile Samsung Galaxy S 4] a103:
Looks like you Odin flashed a stock lollipop firmware. Phase don't do that.

You need to

1. Root the device using CF Autoroot

2. Flash custom recovery TWRP latest version

3. Download the ROM zip file you want to flash NOT the .tar file

4. Put the ROM zip file on external SD card

5. Wipe data factory reset. Wipe internal storage (only if you have external SD card, also back up everything on internal storage)

6. Flash the ROM using custom recovery

7. Reboot.

If above steps seem unfamiliar to you then go to www.galaxys4root.com it has detailed description with videos. You can also watch a lot of videos on rooting, flashing custom recovery and flashing custom ROM on YouTube. Remember to flash a custom ROM you should have a custom recovery installed and to have custom recovery you'll need root permission.

I've used this ROM and it's really good. Even if you don't fish the rom please go through the first 2 posts, it has the installation instruction with a video. It'll give you a lot of info.

Make a back up before you Odin flash the stock.
[T-Mobile Samsung Galaxy S 4] Frankenscript:
It's a hardware problem, which reportedly occurs more in some software/ROM environments than others. It can be caused by:

-A defective SIM that makes intermittent contact with the SIM card reader

-A defective SIM card reader slot that doesn't hold the card against the contacts properly

-A defect in the ribbon cable from the reader to the main board

-A defect in how the ribbon cable connector attaches to the main board.

-Defects on the main board

If you are still under warranty, have Samsung replace the phone.

If you are not under warranty, google around. This is a common S4 defect, caused most commonly byt the ribbon cable attachment. Folks have used bits of squishy foam pressed right onto the cable connector to hold it more tightly against the contacts on the main board. This has solved the problem for lots of people.

When you say you tried flashing the stock rom did you try it through recovery or through Odin?

If you have been trying through recovery try doing it with Odin using a full stock tar file. This will start you over completely from scratch, but should make the phone work.

no wifi on stock rom

Hi I'm having trouble getting my wifi working on stock roms. I can install custom roms with out any trouble with the wifi is working on 4.3 4.4 5.1 in an combination of roms with no problems. The moment I try to install the stock rom that came with the phone via TWRP which is 4.4.4 everything works even BT just not wifi. I've tried stock roms that were rooted and without root. Same problem. So I went as far as putting the phone in download mode and flashing the stock firmware through Odin, which put the phone completely back to stock. Stock recovery, stock rom, no problem right? Wifi still wont work. So I had to flash TWRP through odin and install a custom rom just to get wifi working again. I've tried this twice now and it wasn't just a bad flash. It's not the end of the world considering it only happens to me on stock rom but I still don't understand why it's doing this at all. Any Ideas?
