Swap T-Mobile Mobo into ATT - Galaxy Note 3 Q&A, Help & Troubleshooting

Just a question, wondering if anyone has had an experience with this. I bought a water damaged ATT Note 3 for cheap and the only damaged part inside was the logic board. I know since it has a locked bootloader its a PIA to get root and such. So I was thinking of just swapping in a T-Mobile board. They look the same with connections in the same spots. This would save me a lot of effort. Anyone know about this ?

Just a follow up. Parts swap in perfectly! For anyone interested make sure to replace the radio module at the bottom end of the phone when replacing the logic board. For anyone wanting to rid themselves of a locked bootloader, find yourself a busted Note 3 on the cheap and swap it in.

[Q] SPH-D700 will not turn on or charge

I have been unable to turn on or charge my samsung epic 4G SPH-D700. Here is the facts. It is a sprint pcs phone, and I used it on the sprint network with no modifications to it or custom software. I have been using an Seido 3300 mAh battery for about a month.
Found out that I can charge it if I can manage to get the USB port in the right position, it is loose and probably needs to be replaced because the solder points broke. I was able to find the replacement USB jack.
I cannot post links right now, but the part can be found at globaldirectparts
My question is how am I going to solder those small contacts. I have a solder iron and have soldered dc jacks on to laptop motherboards so I have some experience, but these contacts are just so small, anybody have experience / recommendations for soldering the new jack on?
I like to use a jewelers loupe when soldering very small components and of course you will need an extremely fine tip.

I've tried ordering things from globaldirectparts. They always email me back saying they are out of stock even after I've paaid and I had to wait almost 2 weeks to get the money returned to my account.

Just pay $100 and have it replaced by asurion

still under warranty? may not even cost to replace for a faulty usb.
I bought the phone used and I am currently with virgin mobile. You are right, I could just signup for sprint service with insurance, and make a claim after a few days, but it's something I know I can fix and plus I want to unlock it and use it for boost mobile.
It might still be under warranty? I'll have to see how to make an ram for that.
I can see the contacts very well with my glasses, I mainly need to stabilize it for the de soldering braid.

[Q] Best way to repair water damaged mic?

Unexpectedly got soaked with seawater on vacation with my nexus in my pocket. First of all, out of all of us two cameras, a Samsung midrange android phone, and one of those brick like old Nokia phones all were casualties - only my nexus 4 survived. I think that is pretty impressive.
anyway, it didn't make it through unscathed. The mic does not work and also the gyroscope is pretty wonky. everything else appears intact.
as this was water damage I'm assuming no warranty will cover it. my question is what's the best option at this point and how much is it going to cost?
send it to Google / LG for repair? Try one of these cell phone stores that claim they can repair broken phones? Try and find the part and fix it myself? or just buy a new phone? what's going to be the cheapest?
I would recommend to sell it. The phone is water damaged. Even if you send it to LG or take it to shop to repair mic or gyroscope; other problems will appear sooner or later.

Yep, I'd say get a little bit more money and just get a new one. Keep the old one as a paperweight or something. hahaha

I figured that's probably the best option. Is there no way to tinker around and try and replace the mic with parts that are available on eBay or something until I get together enough cash for another nexus?

There is. Just follow
and replace as necessary. Not sure how long the parts will last. There is a chance that the motherboard would just burn off one day.
My mic has failed too (as well as a portion of my digitizer ugh) and I have decided to order a mic from ebay for $15, I've already opened the N4 up and its super easy to replace so I would say replace it and while your in there look for any corrosion (will look white and chalky) and clean it off with a q-tip and 99% isopropyl alcohol
Water damaged MIC, ordered replacement usb charge port from ebay for £12. Using the video posted, I was able to successfully replaced my fault MIC, phone is working as per normal.
I ordered one from eBay but it looks different from the original. You guys think I should install or send it back? This one has two antenna connections but the original only has one.

LCD Replacement REAL QUICK HELP PLEASE!!!!

If I buy a sprint LCD with digitizer, will I be able to use it with my ATT version? I am trying to replace my screen and bezel since they are damaged.
If I buy the Sprint version, will a ATT sim work? I am thinking about bidding on this. http://www.ebay.com/itm/Samsung-gal...ts_Tools&hash=item20d4064998&autorefresh=true
Let me know quick!
Anyone??
Only have 20 min to make a decision on whether or not to bid on this. Can anyone please help?
Someone hasn't responded because,
1) they haven't seen this thread.
2) nobody knows.
3) nobody has needed to replace theirs.
If you do buy it. Come back and let us know if it worked or not.

you probably could have found the answers doing some searching... but as with 99% of all other phones the AT&T SIM will not really work in the Sprint phone. You should be able to replace the screens between phones, but your best bet would be to find S4 teardowns of AT&T and Sprint phones online and see if the screens are the same. I would suspect the screen and body are the same, but the logic board and chips are different.
In order to find the answer, someone has to be the first to do it... that someone may be you, my friend.

[Q] Motherboard swap

Hi all. i have an s3 with t-mobile uk and last week i broke the screen. Luckily for me my i have aquired an s3, which had been cooked in the microwave and needed a new motherboard but screen all good. long story short swapped motherboards and all good apart from donor phone still being locked to O2 so have no signal. How can i get round this.
thanks in advance.
Why didn't you just swap screens?
Swyped from Tapatalk Pro
Your story is contradictory, your motherboard in the microwaved phone will still be t mobile.
Anyway, to unlock you'll need a network code from O2 or another legitimate source.

Hi,
Just quick question, how could it be on O2 if you swapped the motherboards? You should be on t-mobile like your old phone was. So I think there is a bit of confusion. But that's just my opinion!
Good luck!

basically my t-mobile s3 broken screen. other is microwaved O2 s3. swapped motherboards and all my phone stuff works fine apart from i have no signal. if i go to network operators in settings only O2 is shown and no option for t-mobile/ ee.
That isn't network lock, which appears as soon as you insert a sim card belonging to another network. You have a different issue, probably related to microwaves or water (drying something out is the main reason people microwave electronics, thus destroying it twice over).
Sent from my GT-I9300 using Tapatalk
so would it be right to assume that something else may not be working which is attatched/stuck to back of screen?
p.s. amusingly the microwaved phone was my brothers, he was heating little ones bed time milk but put the wrong hand in the microwave.........
I guess the antenna got fried in the microwave. Try transplanting motherboard and screen into your original case.
Sent from my GT-I9305 using xda app-developers app
The lower PCB is attached to the screen. That's going to be fried.
i turned phone on yesterday to see what i could do via settings. oddly all started working normally. i spent an hour the other day trying to sort it but would only ever detect O2. the motherboard swap was definitley the easy option. a few screws a poke and a prod and bosh.... all done. thanks for yourhelp and suggestions.

Sprint to Verizon (motherboard swap?)

Question In summary:
Has anyone swapped their Verizon motherboard to a sprint model or vise versa and got it to work?
In detail:
Ok so, got my Verizon note 4 wet few weeks back. Didn't realize how wet it got and started it back up too soon, worked fine for about 5 min and then the screen shorted out. After completely drying it still boots, still freaks out from all the messages etc pooring in from it being off, was also able to access from my computer to pull off data.
I was able to locate a mint condition sprint version for a reasonable price, my theory is that I can simply swap my mobo from the old phone to the new sprint one and be good to go. I tore it apart last night and soaked it in rubbing alcohol to clean off any remaining deposits,I'm trying to source a sonic cleaner to do a better job if possible.
Any reason this won't work? Any possibility I could damage the good screen with a bad mobo from the Verizon? Anything else you can think of that I haven't addressed? I suppose I could sell the sprint version and fund an actual Verizon replacement from the sale but if this will work...
bump, looks like i might be the guinea pig...

Why not just get the Sprint phone, unlock it, and just use it on Verizon????
You'll be buying a mint condition phone anyway. Why tear it apart when you can use it on Verizon if unlocked?

I was under the impression that sprint and Verizon run different tech for their networks. If they don't, or if the phone has the hardware to use either, then yes, I'd much prefer to unlock it and go that route. If anyone can confirm that'd be great. I had done a bit of googling on that earlier but everything I found basically said they were not compatible.

Ok, I just researched it and found 2 things:
1) Verizon won't activate any device not bought from Verizon. (According to a forum)
2) Sprint and Verizon use different IMEI types, so one carrier's phone won't work on the other's network.
So I guess you can't actually just use the new phone.
This now brings up the question of how swapping the mobo will affect the IMEI. If using a Sprint mobo will make the phone now have a Sprint IMEI, then you won't be able to get the fixed phone to register on the Verizon network. And, Verizon may not register the device anyway.
