Nope. Good questions.

Once you install the m919 motherboard, you'd need to use the Odin files from the t-mobile thread...

http://xdaforums.com/galaxy-s4-tmobile/general/firmwares-official-mdl-mk2-nb4-t2816508

Not sure about those modules, though... I've never used them.

***MOST IMPORTANT THING... Broken phone has to have a CLEAN IMEI. If it says Blacklisted, it won't work.***

Sim unlocked doesn't matter too much, because you can use region lock away to do that yourself.

Your research probably brought you to this site, but this is what I used as a guide to replace the board...

[AT&T Samsung Galaxy S 4 General] John The Rhino:
None of the Roms listed in the guide are full of bugs it is disrepectful to the hardworking developers to suggest so and if you had read the guide you would know that all have been tested and confirmed to work. Reading saves phones.

[AT&T Samsung Galaxy S 4 General] mswal2846:
Make sure you:

1) get one with a valid IMEI (can check easily online)

2) just has a cracked screen but is working otherwise. A "blank" screen could imply motherboard issues, which you don't want to carry forward to your current phone.
[AT&T Samsung Galaxy S 4 General] Can0dope:
Kinda off topic, but not exactly... I'm curious whether this might work with our device? Has anyone tried it? It appears to work with the I337M, but IIRC that has an unlocked bootloader... I'll be trying it shortly, just wondering if anyone else has.

I just bought a tmobile note 4. What ROM are you using?

[AT&T Samsung Galaxy S 4 General] guut13:
The reason you have to return to nb1 is because nc1, ni1, and nj4 are all updates only. Odin images do not exist. Follow the steps in this guide and you will not brick your phone...

http://xdaforums.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642

You are good to post. But I've never tried it myself. Only one way to find out. Give it a shot and let us know. Just back up first, in case something goes wrong, then you can odin back to stock and restore your back up.

If it works, I'll add to the thread.

I'm using kangapop, but I'm still on an S4. (I just grabbed a m919 motherboard to use in my ATT phone.)

[AT&T Samsung Galaxy S 4 General] guut13:
Nah. You were probably just drunk. I did get a Nexus 6. Even though I really liked stock LP, the phone was just a hair too big so I returned it.

Ended up getting a busted tmobile s4 and stripped it for parts. Now I have the best of both... Stock LP on a smaller phone.
[AT&T Samsung Galaxy S 4 General] pendragon11:
how difficult was swapping out the mobo?
[AT&T Samsung Galaxy S 4 General] guut13:
Easy peasy lemon squeezy.

Just follow the ifixit guide i linked before.
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
If I do end up switching out the Motherboard, would I still be able to receive At&t service? Also, would I flash At&t TWRP, roms, and etc, or would I have to flash the T-Mobile version of TWRP and roms?
[AT&T Samsung Galaxy S 4 General] guut13:
As long as you SIM unlock it, it'll work on AT&T.

You'd treat it like a t-mobile phone... m919 Odin files, m919 version of twrp, etc...

ROMs.. you can pretty much choose whatever you want.
[AT&T Samsung Galaxy S 4 General] mswal2846:
I actually successfully did this. It is really not bad. Replacing the motherboard seems daunting but it's not that bad. I've flashed 3 ROMs over the past 2 days trying to find the one that I like best. With TWRP it's not unlike using SafeStrap (just be sure to get the latest TWRP since the previous version didn't actually save the backup to extCard even when it said it did).

I was fortunate in that the broken phone I bought on ebay was already SIM unlocked. And you need to follow the t-mobile forums for rooting.
[AT&T Samsung Galaxy S 4 General] cyrusalmighty:
Do you still get LTE 4G after switching to the tmobile m919 mobo? I thought At&T Tmobike and verizon all used different LTE bands. I feared I would only get Hspa+. I have already swapped cameras on Sprint and AT&T S4s & taken my old S4 apart due to me dropping in water so I know how easy it is to dis/reassemble. Lol.
[AT&T Samsung Galaxy S 4 General] mswal2846:
Yes, you still get LTE 4G (depending on the ROM). And, also depending on the ROM, you may need to do the setup as described in the OPS under the heading "AT&T APN SETTINGS." I've tried GPE, ECHO, and BHD and got LTE with each on the "M919".

T-Moble and ATT have the same band/type support (there are more details in the forums) and has an Unlocked Boot Loader, hence the recommendation to get a T-Mobile motherboard.

Verizon does not have the same band/type support and has a Locked Boot Loader ... so wouldn't recommend getting that brand of motherboard.
[AT&T Samsung Galaxy S 4 General] Terr20114:
If I'm Lucky I'll get a m919 motherboard today. Keeping my fingers crossed

Got the mobo, running CM12 Beta ? #Finally
[AT&T Samsung Galaxy S 4 General] tuffluck:
So can you replace the tmobile s4 mobo with the one from the ATT phone and then resell it back on eBay as an ATT phone an get your money back?
[AT&T Samsung Galaxy S 4 General] mswal2846:
Well if you're buying a T-Mobil phone that works then just put your SIM card in and go. No need to swap mobo.
[AT&T Samsung Galaxy S 4 General] tuffluck:
So basically, what were saying is the tmobile s4 does not have a locked bootloader? If that's the case then I'm wondering why anyone would suggest swapping mobos in the first place...
[AT&T Samsung Galaxy S 4 General] J.Abaraxas:
Thanks will try. On a sidenote what is the smallest rom available for safestrap? One thats just stock minus all the crap.

Edit: Yeah factory reset after rom installation did the trick but meh lol too dark good featureset
[AT&T Samsung Galaxy S 4 General] t4duzan:
BlackBox is one of the smallest roms I've seen for safestrap. I would say a Google Play Edition (GPE) used to be but uses a different kernal therefore if you're on 4.3 MK2, you can't use it with safestrap.
[AT&T Samsung Galaxy S 4 General] guut13:
Try one that uses the Aroma installer. (Generally the install file size is +1.5GB) Most of them are set up so you can choose which stock apps you want to install or leave off. The OP of the ROMs should tell you if it uses Aroma and what options you have. (Blackbox is the exception since it doesn't have any extra apps to begin with)
[AT&T Samsung Galaxy S 4 General] hovax615@hotmail.com:
Foxhound is also a really small ROM it boots up so quick.

[MENTION=2982241]guut13[/MENTION] I just checked the OP ...... I thought we are ABLE to go back to MK2 using MK2.tar file if we took MLD 4.4.2 KitKat leaked. Also if u would like to update BlackBox V2.3 special instruction would be nice per [MENTION=2059935]xDark-Moonx[/MENTION] 1.Install Rom.zip....... 2.Install MK2 Kernel....... 3.Factory Reset..... fixed rebooting every 30 second issue.... That factory reset would wipe all data, cache and dalvik cache and did the trick ........ Time to working on Dark Venom Hybrid theme ......:thumbup::cool::thumbup:

[AT&T Samsung Galaxy S 4 General] guut13:
Thanks for catching that. I wrote the 4.4.2 section when the thread came out and it was still unknown. Guess I forgot to update it :(

Also added [MENTION=2059935]xDark-Moonx[/MENTION] note to Blackbox.
[AT&T Samsung Galaxy S 4 General] daredevl99:
the blackbox rebooting issue didn't seem to affect my phone. came from latest hyperdrive. did a factory reset, wipe dalvik and cache, installed blackbox 2.3 flashed modules then booted and it was just fine. slower and choppier than hyperdrive so after 10 minutes of rom settle was given and it was still choppy i went back to hyperdrive never once had a unwanted reboot.
[AT&T Samsung Galaxy S 4 General] t4duzan:
When I was on 2.2, I had random reboots. I went back to PurifieD rom and when 2.3 came out I haven't had a random reboot yet. I did not do the wipe on top of the rom because it wasn't needed.
[AT&T Samsung Galaxy S 4 General] an0ther:
Does anyone know of a way to make a flashable zip of the apn settings so I can just flash after installing rom instead of entering all the settings manually? Thanks.
[AT&T Samsung Galaxy S 4 General] guut13:
I've tried it and it doesn't work. It seems the devs bake the APN setting into their ROMs.

From what I've read, APN settings are suppose to get pulled from the /system/etc/apns-conf.xml file. I created a zip that replaced the existing one from one I pulled from my phone after odin back to mk2. After reboot, file was replaced and permissions were correct, but APN setting were unchanged.

Hopefully I'm wrong about that and someone can correct me.

I, too, installed without issue and did not perform a factory wipe after install. That's why I tried to make the note a "just in case", instead of a "requirement".
[AT&T Samsung Galaxy S 4 General] Maribou:
Ouch! I just pulled the apns-conf.xml and added it to a flashable zip. I was just about to try and flash it to see if it worked. You saved me the heartache bro. :good:
[AT&T Samsung Galaxy S 4 General] guut13:
Well, if you have already done all that work, you might as well verify. Maybe it's different depending on the ROM. Can't remember which on i tried it on.
[AT&T Samsung Galaxy S 4 General] Maribou:
Well, I'm just running stock MK2 right now. I'll try safestrapping hyperdrive in a bit, and see if it works.
[AT&T Samsung Galaxy S 4 General] guut13:
Before you wipe, since you are still on stock (and have the correct apns-conf.xml file)... What happens if you go into settings and delete the ATT Phone APN. Does it recreate itself after reboot?
[AT&T Samsung Galaxy S 4 General] Maribou:
It won't let me delete it. The only option is to discard. I even created a temp APN just in case it wouldn't let me leave it blank. :(
[AT&T Samsung Galaxy S 4 General] guut13:
oh well. thanks for trying. hopefully you will have better luck with your zip.

Since it sounds like you know what your doing (or you stayed at a Holiday Inn Express last night), this is my updater-script...

ui_print("Installing ATT LTE APN fix...");

show_progress(1.0,0);

run_program("/sbin/busybox", "mount", "/system");

set_progress(0.33);

package_extract_file("/system/etc/apns-conf.xml", "/system/etc/apns-conf.xml");

set_perm(0, 0, 0644, "/system/etc/apns-conf.xml");

unmount("/system");

set_progress(1.00);

ui_print("Done !");

Look right to you?
[AT&T Samsung Galaxy S 4 General] ted77usa:
Anyone would like to try blackbox-v2.3 with Dark Venom Hybrid Theme..... PM me.......:thumbup::cool::thumbup:

Swyped From MK2 Dark Venom Hybrid SS Edition
[AT&T Samsung Galaxy S 4 General] Maribou:
One again, you saved me LOL. :) I'm not great at all of this, and apparently I must have stayed at a Holiday Inn. :) I was just using a sample cwm zip I found here http://xdaforums.com/showthread.php?t=1721680 . Looks like I missed a lot of stuff! This was the updater-script I was going to use:

ui_print("GS4-MK2-ATT-Default-APN-Settings");
run_program("/sbin/mount", "/dev/block/mmcblk0p2", "/system");
package_extract_dir("system", "/system");
run_program("/sbin/unmount", "/dev/block/mmcblk0p2", "/system");
ui_print("Enjoy!");

Looks like I was way off. I thought since it mounted /system as RW, that I wouldn't have to do anything extra, because it would push the file I had placed in the /system/etc part of the zip. I didn't even think about permissions. I still have so much to learn .. :eek: Mind if I use yours to see if it works?
[AT&T Samsung Galaxy S 4 General] guut13:
Yours might work too. I was calling the specific file. Seems you were calling the entire directory, which your file lives in. Only one way to find out. :)

I used the zip made my titanium backup as a base... so I'm not that far ahead of you ;)

Here is the full zip, see if you have better luck...
[AT&T Samsung Galaxy S 4 General] Maribou:
SWEET! Thank you! I'm installing hyperdrive now. I'll report back with my findings.:cool:
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
Replacing the motherboard would be MUCH LESS cheaper than buying a new S4, which is a quite expensive device. That's why.
[AT&T Samsung Galaxy S 4 General] tuffluck:
If you bought a used tmobile s4 and sold your used ATT s4 it should be approximately an even exchange.
[AT&T Samsung Galaxy S 4 General] mswal2846:
Yes, except you get the unlocked boot loader ... might be worth it :D
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
But doing a little labor to save a good couple hundred bucks is worth it to me.
[AT&T Samsung Galaxy S 4 General] tuffluck:
I don't follow your logic...buy a tmobile s4 on eBay for $200, sell your ATT s4 on eBay for $200. You haven't lost any money.

What am I missing?
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
Used T-Mobile Galaxy S4 with a broken screen (even an LCD) is even cheaper.
[AT&T Samsung Galaxy S 4 General] tuffluck:
How? Read my post again. Buy a used s4 sell a used s4. Assuming you get about the same for one as you paid for the other, your total cost should be almost nothing, $0.

What you're suggesting is spending $75 on a broken phone, doing work on it and hopefully not breaking two phones. Then you are either out $75 or whatever you can get for the new Frankenstein phone you put your ATT mobo in with the broken screen...

Your odds are much better to sell a used phone in good shape and buy a used phone in good shape to offset any cost or chance of screwing up the mobo replacement on either device.
[AT&T Samsung Galaxy S 4 General] guut13:
Yep... Definitely have better odds buying a working phone.

Reasons I bought a broken phone and replaced the motherboard.

1. didn't want to deal with the hassle of selling. I've already been burned before and don't need the headache again.

2. ebay charges you 12% of your sale price, (but there other options like swappa or craigs list)

3. a lot more i337 than m919 available, so the average sale price for m919 are higher than i337

in the end, the cost to buy broken was same... minus the headache. Besides, I felt confident as long as the description said, "powers on and makes boot up sound" that the mobo was good. The tricky part is the clean IMEI (which you deal with regardless of condition of phone)
[AT&T Samsung Galaxy S 4 General] tus1109:
I got a tmobile motherboard from an sch 545 which was advertised as a m919 phone and replaced it on my phone. It worked but my problem is that the cable that comes from the daughter board is about a millimeter too short so there is no way to get my home and soft keys to work. Any help would be appreciated.
[AT&T Samsung Galaxy S 4 General] guut13:
No clue. sch 545 is a verizon s4. Even if you were able to get it to work, it's bootloader is locked.

I suggest that you return it as "not as described".
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
Either way, aren't the phones SIM Locked? Also, the At&t Service. Will you be able to get At&t service? I would think buying the phone on contract then buying a used cracked one would save a good bit of money.
[AT&T Samsung Galaxy S 4 General] tuffluck:
I hear ya. I'd almost rather just buy a used nexus 5 or HTC product to get an AOSP experience with less hassle.

And yeah eBay fees are ridiculous, it used to be only like 3%. Also, PayPal charges 3% too which stinks. I find selling electronics are still less of a hassle to sell on eBay vs CL even if you wind up losing $25 in fees. Too many flakes on CL, you could easily spend $25 in gas driving around town getting stood up by CL'ers ;)
[AT&T Samsung Galaxy S 4 General] mswal2846:
You can get the phones unlocked (I did by calling them). Your AT&T SIM will work in the T-Mobil phone with AT&T service just fine ( I'm using it as I type).
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
I might not do the whole new phone thing since Surge is getting closer to completing the Kexec project. He has a Pre-Alpha SS 3.82 which is using the new Kexec process. I don't recommend using it since we don't even have any kernels to boot with it yet, and it's not exactly ready to be used as a regular recovery since the settings weren't implemented. He just focused on the way it works, not cosmetics. It's just some news that I thought some of you might be interested in.
[AT&T Samsung Galaxy S 4 General] t4duzan:
So, is this a possibility of us that use Safestrap to not have to use it anymore? Or are you saying we'll have to our locked kernels no matter what?

Thanks for the info.
[AT&T Samsung Galaxy S 4 General] NighthawkXL:
Your jumping the gun, that version of Safestrap doesn't have a working kexec method yet. It allows the loading of modules to help in the development of kexec for our devices. To my recollection Surge is still stuck on finding a way to flush the cache and bringing the CPU's back online without spitting out an error. Did I miss anything [MENTION=4939386]Surge1223[/MENTION] ~ Last thing we need is people running around with that SS version when it's not ready for use as daily recovery drop-in.
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
Yeah sorry that's what I meant. The modules not kernels. I stated that I do not recommend it for usage, but they can use it if they want. Just wanted to give out an update. Just thought the community should know. If someone does mess up their phone it's their fault for not knowing how to install and/or properly operate it.
[AT&T Samsung Galaxy S 4 General] Surge1223:
More or less right, the cache flushing isn't the problem per se but it causes a problem or leads to a problem. Main issue is probably in remapping code and more specifically cpu v7 reset and turning mmu off and on correctly. Maybe a secondary cpu reset issue as well.
[AT&T Samsung Galaxy S 4 General] Terr20114:
I was talking to some guys about the locked i337 bootloader they said that they cant unlock it but they can use JTAG to bring it back to the old bootloader that allows flashing of Roms. Since I'm using a m919 mobo right now I wouldn't be able to try that, do you think they're telling the truth?
[AT&T Samsung Galaxy S 4 General] NighthawkXL:
Nah, even JTAG can't downgrade our firmwares below MF3 because of the blown qFuse inside our motherboard. In your case since your on a M919 board (T-Mobile / MetroPCS) you already have the ability to flash a custom recovery (CWM, TWRP) without any issue since your bootloader is unlocked anyway. There's plenty of info on this over in the T-Mobile subforum ~ I'm thinking about swapping motherboards myself I just have to wait to have some extra cash on hand before picking one up on eBay.
[AT&T Samsung Galaxy S 4 General] Sterben Pistole:
I'm wondering about this qFuse... I know that once it's blown downgrading isn't an option. Since it's hardware would it be repairable? I'm also curious why people are scared the Knox counter will hit 0x1 I don't really get why it's a big deal...
[AT&T Samsung Galaxy S 4 General] NighthawkXL:
To my recollection the qFuse in question is located inside the Qualcomm CPU itself, it would be nigh impossible to fix since it's one of the microscopic connections inside the processor die. Basically, there is nothing that can be done to repair it, at least to the average user (most of us don't have electron microscopes, and the tools to repair CPU's). You either replace the board, or you stick with a blown qFuse.
