Swapping mother boards. - Galaxy Note 3 Q&A, Help & Troubleshooting

So as the title states, I currently have a SM-N900. I was messing around yesterday and I wanted to install A sm 900t motherboard in this device after installing the motherboard from my T-Mobile Note 3 put it back together and everything I want to power on my device and it wouldn't power on any idea what it could be. Any help is greatly appreciated I figured if I put the other motherboard and at least get some 4G LTE since I like it on here H+

Does the 900t motherboard work with the original screen?

The 900T has a broken screen an digitizer. So I can't see anything on screen. But it does power up

Maybe something is damaged in the sm-900? Does the sm-900 work with its original motherboard?

Yes. I'm currently using the N900. Was just hoping in swapping the motherboard out, but that wouldn't work

Sounds the the parts are not completely interchangeable even though the 900t motherboard fits in the n900.

Screen is weird

Hi, my phone started showing my screen in the attached today.
Basically it has all these lines running through it and I have to have the phone on max brightness to see. I've sent my phone screenshot to other people and they see my screenshot just fine. So I know it has something to do with my AT&T galaxy s4 screen.
I had someone else take my phones screen and sent it to me. I've attached it below
I was wondering if you guys know what's wrong with it? Is it a hardware or software problem? Can I get w replacement for it?

The screen is messed up. I'd get a warranty replacement. What firmware are you on? A replacement will probably be on mf3.
I'm on MDL right now.
Do you think Odin may fix the issue as well? I'm away from home so I do not have access to pc yet. If not then should I call straight to samsung or at&t?
The phone screen is messed up even during booting and recovery mod. But I can still use the phone in home screen and lock screen only with max brightness and having those lines on it.

If it was me I'd give odin a shot. That way you can confirm it's a hardware issue.
That is a hardware issue. A flex cable came loose and isn't sitting properly. You could take the device apart and check the flex connections. This used to happens to me all the time on my Nexus 7 until I hot glued that sucker down.

Great to hear that. At least it's a 'do it yourself' fixable issue.
If I open my galaxy s4, I will lose the warranty right? Should I contact Samsung first or go ahead and open my phone?

It would depend to me what firmware you're on. If you're already on mf3 I'd get the warranty. But if you're on mdl then it would be a tougher choice. But I like to have a custom recovery and the ability to put custom roms on. A warranty most likely will have mf3.

No warranty stickers on or in the device other than moisture detection stickers. Just don't lose or strip the heads and you will be fine if you ever need to RMA.

Simply opening it up won't necessarily void your warranty.
The connector for the display is on the upper right side by the volume rocker. (see attached image)
It's only a couple of screws and you'll need a spurger or guitar pick to open it up.
Simply press on the connector to make sure it's seated properly.

Nice! I'm assuming that is the board for galaxy s4. And will doing this most likely fix the issue?
Thank you for the image though

Pop it up then re-seat it. Should do the trick.

I'm finally home to be able to open up my phone and to pop it up then re-seat it but the problem still remains. Is it still a hardware issue?
The screen itself is more than likely shot.

Alright, I am thinking of exchanging this device through samsung. How do I restore this device from using a custom rom to factory stock through odin/triangle away. I also want to restore it without using the factory boot recovery as I am unable to see/navigate through that.
But my approach is (would like some input)
- Reset Counter using Triangle Away on a custom rom (task's at&t galaxy s4 aokp rom)
- ODIN (removes root and go back to at&t s4 stock rom - MDL)
- Reset to factory through "System Settings -> Backup & Reset"
Is that correct? I need it in stock form as Samsung most likely to check everything through my device and be able to fix the lcd screen.
Wanted to inform people that have tried to help me out... I sent my device to samsung and they were able to repair my phone as there were no solutions besides replacing my LCD screen for free due to warranty. I finally received my device back after waiting for 2 weeks.
nfortunately, they updated the firmware to mf3 and there are no ways to revert back even with my old nandroid i backed up using twrp. As of now, no safe rooting method is available for mf3
There is a Safe root method. The only way it is not safe is if the user screws up by not reading.
Sounds like they fully replaced the device. If they did not fully replace it, contact them and tell them that they had no authorization to update the phone. They were ONLY to repair the phone. Tell them you want a replacement with MDL and give them some BS story that you have vital applications for work that is not compatible with MF3 or something like that.

Sounds legit. Consent should be a must to make any changes to a users device that doesn't involve 'repairing.' But hey... What's customer service anyway? Lol.
Sent from my GT-I9505G using xda app-developers app
I don't think I'll return it as I am returning to school soon. The only thing that is holding me back from rooting is there are no methods to unroot/odin the s4 on mf3 firmware.
On the bright side my phone doesn't overheat as it used to be and lasting longer battery life. Not sure if it's mf3 firmware but it's doing fine as it is. Will wait patiently for a possibility for unroot/odin.
Keep this in mind.

LG Flash gives you IMEI while attempting to flash a ROM if I remember correctly.
Type #*06# to get your device's IMEI.

Sometimes they put it into the SIM Cover, the tiny thing holding the SIM. SIM Tray. No? (Or that was just the iPhone..., can't look now, using it)

You can plug usb mouse on micro usb adapter and check your imei.
turn off your device.
Press and hold volume up + power + volume down. A "Hardware key control mode" will appear.
Your imei is displayed don't above the barcode label.
Great, i didn't know this menu, thank's.

hello Zombie,
Thanks you are right, i found the sticker inside the back cover.
I misread your response thinking it was outside the back cover.
by the way, is it true that if the LG G2 main circuit board is swapp or change, the default imei number will also be changed ?
Sent from my SGH-T959 using XDA Free mobile app
I Wish I could take off the back cover and remove the battery from mine. Not installing a custom ROM because of this.
I boot Looped my Note 2 a couple times had to battery pull. I had tested quite a few ROMs on it.

if each board comes out with its own imei then yes if the board is switched then the imei also changes, I'm not too sure what's the process for the imei to be put into a phone or how they assign it

S5 Sm -900x working phone by changing motherboard ??

HI everyone I have a live demo unit 900x and was wondering is it possible to just change the motherboard with say a 900f and it would work normally ?
I don't see why it wouldn't work as the motherboard is the phone heart. Wouldn't want to know the cost of a new board tho...

Replacing i9505 vibrator

Seen a video on YouTube, doesn't look too hard but want to be extra safe because I've never opened the s4 ever. So has anyone managed to replace the vibrator without messing anything up and how hard is it?

hi mate,
I replaced a few things on the S4 before never the vibrator , except the LCD/digitizer the rest is fairly easy...of course depends on how skill you are.
to open the body use a guitar pick or a corner of and old plastic card ( credit card type ) to wiggle between both parts of the phone body
