[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] EeeK:
Hi all, I just got this Samsung S3 model i9300 with a damaged motherboard and another model i9305 with a damaged screen.

Already dismantled both the phone as seen here:

Please advise what should I do with the i9300 front panel or the i9305 motherboard, if possible with pictures, so I can have a working phone.

Is is possible to test it first by placing the i9350 motherboard onto the i9300 front panel without any screws? Do I need to provide any insulation to prevent any short-circuit?

Putting the 9305 board on the 9300 display will have issues, no doubt.

I'd just recomment you to check the post #11 on this thread: http://xdaforums.com/showpost.php?p=48678568&postcount=11

Based on that, put some adhesive tape on the conflictive parts of the board. Just to test it, it will be ok, but be careful if you try to put the back housing and its screws.

You will need to grind and sand some zones on the housing too.

Just be careful and do the things with patience and slowly.

Good luck!

I managed to test it with a piece of paper underneath the motherboard and it boot up with this screen

Can I flashed the latest official firmware without the home button? I tried to use the Samsung Skies, firmware upgrade and initialization but it required the phone to be on recovery mode.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Dpetry:
I don't think you can flash it without the home button. You'll need to use the button to get to the download or recovery mode.

At least you know it is working (just need to test the SIM card).

Use the front bezel, lcd and glass of the i9300, and the back bezel and motherboard of the i9305. The back needs to be from the 9305 because of the 4G antenna that has 3 words instead of two. Don't worry, these wires connect on contact, when you close the casing.

What you need to do know is to use a dremmel to make way for the bulkier motherboard of the i9305.

Look for the photo that was posted previously, with the green marks on where you need to use the tool.

Start covering the holes (where you can see the board) with electric tape.

I started from the bottom. The first two parts were very easy. The most difficult was the big part that one the left, specially because it is so close to the circuit hole.

Always clear the dust and try closing the front piece with the motherboard and the back piece. It doesn't need to be perfect, but you can work your way through until it becomes perfect.

Alway remove the tape before trying to close the case and reapply it before using the dremmel. There will be lots of dust.

AVOID TURNING ON THE PHONE WHILE TESTING THE CLOSURE OF THE CASE: exposed metal parts can make contact with the motherboard. So just test the physical closure of the case and once is perfect continue to the next step.

Once you dremmel'd enough apply tape on the board and paint the exposed metal in the frame. Don't worry if a little paint falls in the board, it happened to me. Just let it dry for a day or two. The paint does not conduct electricity and that's why your painting it, to avoid making short circuits.

After the paint is dry remove the tape and check is any parts have contact, I used and multimeter for that.

After that just close everything and you're set.

You can find lots of tutorials about resetting the phone using download or recovery mode in Google.

Thanks for your posts, I'm now using my s3 i9300/i9305 and have flashed it with a lollipop rom, nameless, and it's like a new phone!

I've put the whole thing back and the back cover fit fine except it the lower left corner as shown here

I believe this caused by the lower left corner where you mentioned it's the most difficult part. I didn't do much on the first two parts which you mentioned is easy.

Can you provide me a picture on how yours look like?
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] jedikalimero:
Hi,

Yes, it can be done but it is a very difficult process. If you fail just one millimetre, you can end up with a non functional screen.

Yes, you can test your working motherboard on the working screen without doing any previous customization. It will not fit properly and you probably will not be able to text the home button because the pins will not reach the motherboard but you can see that everything else is fine. Also, the back cover (the internal back cover, not the battery cover) will not fit so probably some antennas will not work.

Ok, so you need to use a dremel with a file tip to remove the parts from the metal frame of the i9300 screen that don't allow the i9305 motherboard to fit correctly. In the aforementioned thread those parts are marked in green in my picture of the i9300 screen. so you have to remove 3 parts, one of them so the back cover of the i9305 fits and then cover the removed bits with paint to avoid short circuits. I tried it and failed. I missed the control of the dremel for a second and damaged two tracks of the square chip resulting in a screen with the image working but not the touch sensor. but I can say that if I hadn't damaged the tracks, it would have worked perfectly.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] EeeK:
Put on a case and using it without anything done on the board.

All things work fine except vibration, any idea how to troubleshoot this?

Could this be caused by the contact between the i9305 board and the 9300 mid panel?
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] mrhugofernandes:
Depending what parts u replace

Ok , so lets say if you replace the front Glass ONLY, it will fit both models.

You can get either model screen to fit whichever model phone, AS LONG AS THE SCREEN DOESNT COME WITH THE FRAME. the difference in the screens are the frame on the screen, as someone said the board has a different shape so it would need the right model screen. However if you buy the full screen without the frame, and fit it on the old frame, it will fit .

Hope that helps

Koreans 3 - me 0

Has anybody had this problem and have found a way to fix it?!?!?

I've tired this same process 3 times. First one was about 18 months ago. Unlike some of you, every time I've tired this it doesn't recognize the sim and the IMEI number is "Unknown". Is this just the result of shortage or is the quadcomm really dead? I've got three 19305's laying around, every single one has the same story: cracked glass-> tired to replace just glass -> (1st time heated just a bit too much and everything was pink| 2nd time cracked the screen while removing glass | 3rd time damaged some cables while removing it) ==>> 3 i9305's working perfectly but not recocnizing the sim (or IMEI, and thus not connecting to a network) and one i9300 front piece with display and some metal pieces removed...

Please tell me this is something just needing some sort of reset.....:crying:

I have i9300 have a broken board (to be replaced), and the screen and the touch screen work, as it is known that the i9300 is slow because it does not have enough memory.

I am looking for information whether the work, according to the scheme with it.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Traace:
Don't know if anyone still need the information.

I've dis- and reassembled much i9300 models.

The i9305 does! fit into a i9300, more or less. Used all parts from i9300 even the backframe. Dont turn the screws to hard, do it soft ;) Keep care that the board don't bend and strongly avoid to put pressure on the board or the frame itself, if there is some plastic hitting the board, cut it away.

For the Homebutton, locate the 2 connector pins on the mainboard, then bend them up a bit, keep care that u don't brake it.

The Antanna is working out of the box with i9300 backframe(If its doesn't at yours, bend the connector pins too, stay careful ofc), can't test LTE Network at all as i dont use it, but it should work too.

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Traace:
Yes, all working as it should, no issue but LTE Network is still untested. However i recommend to use the original i9305 digitizer ofc. This here is just a workaround.

From my side there is no need to see a video. If u still need support i can show u what to bend (still have some broken eMMC/IC Power boards here anyway) but it should be clear already.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] edgi100:
what digitizer ofc? you mean to use the original display module from the i9305?

The problem is that no one can say with confidence: "Yes WORKS! Take screen from i9300 and the motherboard from the i9305 (a bit to finish the housing as described in the first post), and everyone will work for you." Wrote above that are not advised to collect the phone from different models. But no one says why and what can happen.

I have a display module from the i9300 sell me it will be difficult, so I think or I throw at a completely new phone, or I'm saving both and buy a motherboard from the i9305 will all work for me, and I will be happy.

Thank you answer that, I'm sorry for my English.

If u don't wanna or can't risk something, i can understand that. But why u waste days after days thinking about? Just do it or not!

I wasn't scared to break it at all because sometimes i get these mainboards for around 5$ each.... + NO Risk NO Fun

If your uncertain with it. I advice to sell your i9300 digitizer and get a proper i9305 one afterwards

U never hear about digitizer ? Its a common word here

Digitizer means the ->Display,Glass and sideframe<- its bind as one part:

hello!

You are a $ 5 value, and we have a motherboard (not new) cost about $ 28-30 per share. By this, I am afraid to buy the motherboard from the i9305, it will not work if I should not spend money.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] ModdaTron:
Annoying thing

Still, I believe there is a solution and it consists in using a Dremel tool to remove all the aforementioned parts of the i9300 metal frame so the i9305 motherboard and middle cover fit correctly.

Some precautions have to be taken. Covering the holes in the frame to avoid metal splinters entering the LCD circuits and painting the removed parts properly to avoid contact of the metal with the motherboard circuits.

I haven't tried it personally but I'm probable going to do it this weekend so I will tell you how it goes.

And next some pictures illustrating everything I explained:[/QUOTE]

Hello! I really don't know if this is a genuine reply but I'm new over here :D

I want to ask if anyone know the name of that "rubber" (I think) which isolate the motherboard of the LCD "chassis" .

My motherboard overheat really bad and I need an idea about how I can isolate that part of "chassis" (I forgot to mention that I was removed that 'rubber' to increase the chances my I9305's motherboard fit into i9300's "chassis" , and yeah..now I've got this trouble).

I'm willing to try that Dremel tool but I wish to try an easy way first :D

i9305 motherboard in an i9300 phone

Hello,

I think you are talking about the thermal pad, you should not remove it.

I would like to thanks everyone , I arrived here by googling my issue : i9305 i9300 motherboard in a phone ( the phone did not read the sim card Because of the pressure on the flex cable sim ) . After I read this thread , I used a small flat screwdriver ( since I have not a dremel ) to trim the frame under the motherboard as described and by covering the scratched parts with an insulating tape for high temp ( I have not That Particular paint ) . Actually everything Seems to work , obviously the 4g is not working Because of the antenna, but the LTE yes , Also the home button is working . I'm satisfied since I repaired this phone with a 20€ mainboard and an hour of work. Thank you

managed to get 4G network

Hi everybody,

since my galaxy s3 showed me white screen of death after years of service it came to my mind naturally to seek a new motherboard, but I was already feeling the frustration of not having a 4G compatible device.

I decided since to think about substituting the dead S3 mobo with an S3 LTE one and that was the reason I came across this thread by googling.

I managed to buy a cheap S3 LTE mobo for less than 8$ and I worked on it.

the first time I just put it in place with S3 LCD after changing antenna and I faced the following problems:

- no network (either no service or no network bars with emergency calls only)

- mobile becomes very hot (in the bottom around sim reader) and drains battery very fast

- mobo didn't fit well

- home button does not respond

by reading your these posts I could identify whether these symptoms are software or hardware related because in the first time I thought that it's just a matter of rom in dealing with the no network symtom

to overcome these problems or at least some of them, I have put a small piece of electric tape on the area around the left bottom screw to isolate it from mobo and the abnormal heat disappears at once ==> there was a short-circuit like there.

I changed the sim to use another one from another carrier and the network worked perfect.

the home button of course still doesn't respond and I prefer not to bend those pins for the moment

I've done that this way waiting to find a simple way to trim those areas causing it not to fit perfectly

any idea about the reason why network works perfectly with one carrier but not with the others?

another succesfull story

eMMC died in my i9300 and after countless hours of trying to revive it and finding this thread I finally decided to upgrade it to i9305, so I ordered tested-as-working (wanted to be sure that it was fully functional so there would be no doubt if I messed something up in the process) i9305 MoBo for around $25 and as soon as it arrived I started the process of careful dremeling the metal pieces. I used thin clear office tape to cover holes exposing display's PCB (it was pretty tricky as they are directly next to places I was working on, in hindsight I think it would be better to cut out mask from paper to cover everything except place I was working on) and used medium-sized flat-headed screwdriver to cover delicate chips from accidentally slipping dremel head and damaging it. After evening out frame "separator" to same height as its top-end and taking out little off metal near bottom-left screw hole (look at the pictures in first post on the second page of this thread) I put everything back together, but SIM couldn't be recognized and corner near back button was getting pretty hot, so I put a piece of clear tape on demeled place near bottom-left screw hole, which soled the issue. Everything is working except of LTE, which is working, but not very reliably, still sometimes reaches better speeds than 3G.
