Swap motherboard 2 different S3 model - Sprint Samsung Galaxy S III

Hi,
I have a Samsung Galaxy S III i747 [http://forum.xda-developers.com/galaxy-s3-att]. I tried to repair it but the glue I used to previously repair the glass was too strong and the digitizer came with it... Trying to power it and all I see is green light a part of the screen and nothing but the phone vibrate on start-up. I think the motherboard is still good.
I looked for local classified for broken screen (or used S3) but so far I wasn`t able to grab one and some times the seller are asking very high price (120$) for a phone I risk to break. I was thinking just buying a working one in good condition but that`s 200$. The idea is to swap the motherboard and sell the motherboard un-used.
I decided to check on ebay There are a lot of cheap bad esn phone on ebay with excellent screen condition but these are sprint phones (SPH-L710).
I wonder if I could still swap the motherboard and have a roger i747 phone? That would be the cheapest and easiest option for me if that`s the case.

Also, would the display work on the i747? After some research it was said some where that a T-mobile can accept a sprint display - would it be the case for a roger (ATT) S3?
It seems like it is possible to switch the mother board but I will need to also switch the antenna. The display exchange would probably be the easiest.

AT&T Galaxy S3 lcd/digitizer replacement using Sprint Galaxy S3 parts

I have a question about screen lcd/digitizer replacement . I have an AT&T GS3 with a cracked screen, can it be replaced by using a working lcd/digitizer from a Sprint GS3? Are they compatible (same part?) and has anyone done this before? Thanks for your input on this matter.
Check youtube for guides that take both the att and sprint galaxy s3 apart and compare it that way. Most of the youtube guides go pretty in depth.

Did you ever find out the answer to this question? I'm wondering the same thing...
My brother-in-law cracked the screen of his Verizon S3 and was looking for another screen on ebay, but the cheapest ones were the Sprint versions. I proposed an experiment to see if my At&t digitizer would work on his. I took both phones apart and put my digitizer on his phone and everything worked flawlessly. That led me to believe that all the S3 digitizers were cross compatible.

I just broke my screen last night and I want to know this too, I can;t seem to find a digitizer for an at&t s3 but i can find a butload of sprint s3 digitizers. I guess I'll just have to guinea pig up and do it to find out and I'll let you guys know.
a little background on my s3 though. I bought it from at&t on the 1st of this month, it arrived on the 4th, and it broke last night when it fell approximately 3 inches onto the concrete while i was laying down talking on the phone. bing bang boom shatterded in like 5 places. FROM A 3 INCH DROP!!! gorilla glass my butt. I had my motorola atrix 4g for 2 years and dropped it ma ny times from much higher. I even threw it down once in a drunken fit and it was fine. upset!
I am curious about this as well....Was it successful?

I know for a fact that the Sprint LCD digitizer does not work on a Verizon phone if you are using the frame with the digitizer. If you try it the back cover does not go on all the way and your home key will not function, microphone creates an echo, and camera front and back may not work. The housing on Sprint is smaller on which LCD digitizer is affix too.
check out the video i did on my screen replacement

What about the LCD itself? The videos show the LCD and glass digitizer are glued together and a PITA to get apart, so maybe it's not worth it.
Ordered Sprint LCD
Hi guys i'll update you when the lcd arrives.
Compatibility
At&t, TMobile or GTI9300 board will not fit in Sprint housing.

God damn it I wish you posted that 48 hours earlier.
Anyway! I bought a Sprint SIII digitizer/housing to repair my AT&T SIII with.
Results:
Yeah, it works. Sorta.
Problem 1:
So the clock battery on the AT&T board makes the whole thing stick out (and your power button not work) so I put a piece of rolled up tape up to the power button to push it down. So that works fine (except that it's ugly).
Problem 2:
No home button. I'm OK with that, I just turned on the on-screen keys on CM10.
Problem 3:
Bottom...housing. It just doesn't fit right. It's loose. I can live with it.
Conclusion:
It's fine if you want to use a slim case for the back of your SIII because it'll be a bit loose (unlike the Euro housing which just outright doesn't work).
Good luck and I should not have bought the Sprint housing but I'll live with it!
EDIT/Update:
In case anyone cares: I filed down the left side of the phone with sand paper... It works fine.
I gave up on the middle bottom (because it's just not the same damn size), I removed the piece of plastic that allows access to the random developer?? pins.
Overall, it works OK. If you happen to see a sprint housing on ebay for real cheap then go ahead I guess. I wouldnt especially recommend it. I'm just gonna get a case to hide the slight gap/lump/whatever from the processor not fitting right. My Nexus 4 comes tomorrow, so I'm giving it away anyway....blah.
Sprint LCD with Frame doesn't fit
Like bastardinator I ordered a sprint LCD with the frame still attached to it and apparently it doesn't fit because the sprint s3 doesn't have a sim slot so the i747 motherboard with the sim slot wouldn't fit in the sprint frame/housing. I did however find out that any s3 lcd sold without the frame would work on any s3 such as this one:

Is the Sprint housing the only one that's different? And can you swap the LCD/glass in between models, as long as you don't swap the frame?

The only manufacturers that share frames are:
ATT i747 & T Mobile T999
Verizon i535 & US Cellular R530
International i9300 unique to itself
Sprint L710 unique to itself
Now of course a bare Digitizer Amoled inlay without frame is universal.
Hope that helps and here are some high quality videos that show glass replacement from start to finish.

I have a Verizon S3 and purchased a Sprint S3 digitizer w/ casing from ebay. I plugged it in and it worked great, but just like others it doesn't fit quite right. I then noticed that the casing for the Verizon and Sprint phones differed slightly because the motherboards are put together differently. So I took a dremmel to the casing of the Sprint digitizer to match the Verizon casing. I am nearly finished modding the casing and the motherboard sits almost perfectly inside the casing. One thing I have left to do is apply some rubber paint/cement to the areas I ground down because the casing is actually aluminum and I don't want the motherboard to short. I will try to post pics later of what I have finished so far.
help!

I'd like to know;
Are the GT i9300 universally compatible? I need to know which will work with the Verizon version. Also does anyone have an idea what type of paint should be used for the frame?

No the I9300 and Sprint L710 are not compatible with one another or any other variants. Verizon i535 and US Cellular R530 are the same and AT&T i747 and Tmobile T999 are the same... :beer:

Ok so I have read through all of these post about using sprint parts to repair an ATT S3, but I can't help but ask again for more clarification. I know the ATT and Tmobile share the same frame, but like others have said there isn't much out there for cheap. So if i got a Sprint S3 digitzer frame with power button and volume rocker still, then put my logic board and the plastic piece that goes on it and then say I use an extended battery with a backshell that extends would that work? I read in one spot that the clock battery causes issues where exactly is the clock battery on the att phone seems like the biggest thing I have seen is the vibration motor. Sorry to beat this into the fround :-/ thank you again.

n7100 owner in the USA, dropped my phone and cracked screen

Hello fellow n7100 owners. All input welcome, but especially from other US residents who own n7100s.
So I did something stupid this weekend. I wore these loose shorts with loose pockets and dropped my phone when I sat in my car.
The screen is cracked now at the top right. It turns on just fine, works as usual, and the touch sensitivity also seems to be normal in the area of the crack. So it seems like the problem is just cosmetic at this point, , and in a darkly lit room, it's hard to even see the cracks when the screen is own.
But it's bothering me to look at it, I really liked the way this phone looked and kept my screen and everything in absolutely immaculate condition before this. What are my options?
I figure I can't send it to samsung, since I bought it off ebay, and obviously it's not a domestic galaxy note 2.
I'm thinking self repair is a no go, unless it's very easy and doesn't require a lot of tools because I am not handy at all with those types of things. I was thinking of taking it to a local repair shop that I found online, but I don't know how much it's gonna cost...and if I do take it there, if I should buy the parts I need beforehand so they don't overcharge me on those.
Any thoughts?
Anyone? Someone?
I wouldn't even think of trying it yourself. I wouldn't even try it myself. Your out of luck when it comes to warranty as you bought the device second hand. Your best bet is to find a store like you have and get an estimate
If I am correct, I know you could go to Samsung and let them repair it. Just say you'll pay for it.
I changed only the glass on my 2nd s3 it cost me £15 for the glass and £20 for the heatgun. Check out youtube for tuts

Call up mobiletechvideo.com. they're located in Texas. They swap out emmc chips in Samsung phones so I would assume they can do screens too unless they can't source them.

I got my note 2 as a gift, but when I received it, the screen near the front camera was cracked out the box. So, called Samsung service centre, they say they wouldnt repair it because it was out of their warranty, and if I wanna fix it, it will cost approximately $200 dollars (converted from Indonesian Rupiah).

Time to ¸literally throw my S3 in the trash?

Hi Guys,
So my S3 bit the dust last week and I have gotten an Nexus 5 as a replacement.
My S3 has three major issues and I am trying to decide what if anything to do with it, or what the possible value of it is.
This is a 32gb model locked to my local carrier (Rogers)
1. The glass has a crack, it fell while out of my Otterbox and the glass got a spider crack on it, the LCD panel and digitizer were still working perfectly fine last time I used it a week ago. The screen protector is on top of the glass.
2. the OS is screwed up, I was having issues with the modem and connecting to my carrier and SIM and flashed a .zip file with a baseband and it caused my phone to instantly hardbrick.
3. I thought a JTAG servicing would revive the device back to stock OS so I brought it into a local shop for the JTAG (and then likely the glass replacement if they could get the S3 unbricked) they told me that the IC power chip in the device is broken. How that happened I have no idea, last thing I did with the phone was flash a .zip file to it via ClockworkMod Recovery, no idea how doing THAT broke an actual chip in the board of the phone.
So now I have a device that is screwed on three levels.
Any idea what I should do with it now. Anyone had experience with a broken IC chip? Is it worth anything on the ebay market for parts?
I see people selling the IC chip online but I am not even going to attempt soldering things to the main board.
nobody?
bueller?
you can get a replacement glass for less than 20 USD
Jtag... anybody's guess
bad chip? possibly damaged when it fell (cracked traces, etc)
I'd try to fix the first 2, but that 3rd one is a nail in the coffin. For what its worth, these things are second rate in less than a year and obsolete in 3.
It might be time to move on.
I would post an ad to see if anybody would like to buy it for spare parts. If you get no responses after a while, I would toss it in the trash.

Will the tmobile S4 motherboard work with any S4 Varient?

So basically with my backup phone S4 it dropped on its side with the case on it. Now the screen is not responsive to my touches at all.
Glass is not cracked. Up under glass in top left hand corner i can see small spider web. Along left side of the phone there is a grey,green and red thin lines.
I know my option is to replace the lcd, digitizer and screen all in one piece but for the price and repair trouble Im thinking of just buying a BAD ESN S4 off ebay that have a perfect display and just swap the motherboard from my phone to the phone I buy on Ebay and put the Ebay phone motherboard into my backup S4 and then sell that phone on ebay to get some of my cash back
My question is, can I use any S4 to do this? Will the tmobile motherboard work with any S4 meaning will it fit? is there any differences in the build?

[T999L] Broken screen donors. What will fit and work?

I know SCH-R530x and R530 and I think SCH-I535 are all compatible. The sprint version (SPH-L710) is not, doesn't line up. I fixed a 530 this way by using bad ESN 530x donors with good LCDs. No glue, no mess.
On the GSM side I tried to do the same. I have a T999L where the digitizer appears cracked but the LCD doesn't show any signs of life either. I tried to install the motherboard but while the screen worked, the metal body didn't line up.
I was able to mill out whatever didn't fit but unfortunately the T999L motherboard refuses to charge in the R530x body. In the original body it charges OK so I know its not the charging port or battery terminals. Its either shorting, misaligned or something else???
So what will work here... I got the phone for $12 and I need a screen. Replacements are $40 from China and require all kinds of painful disassembly.
Will the T999 work as a donor? How about the AT&T SGH-i747? Seeing some pictures online it appears both phones have the correct spacing near the power button. Has anyone done it?
Would any international S3's work?
