Hello, my note 5 screen broke. Can I take the motherboard out and stick it in another note 5 to recover my files? Also the usb port is broken too, Going to use wifi if I can swap the boards. Thanks for any info on this.

It is hard, but possible. But perhaps you can try to copy the files and migrate to a new Samsung device instead with Samsung's Smartswitch app. If your screen is totally broken to the point you can't operate the phone, use Sidesync app on both your PC and phone, then control it from there to use the Smartswitch app.
Yes. This is 100% possible and relatively easy.
Step 1: Use a heat gun to soften the adhesive behind back glass (hairdryer on HIGH works as well). Then SLOWLY AND CAREFULLY use a razor blade to separate the back glass from device.
Step 2: Remove all 19 screws from the back of the device.
Step 3: While gripping the frame of the phone, gently apply pressure to the bottom of the battery below the wireless charging pad. This will allow the motherboard and screen assembly to separate from the frame.
Step 4: Separate the motherboard from the charge port flex cable. (Start at the top of the motherboard and work your way down.)
Step 5: Repeat process in reverse for assembly into host device.
Please note:
If you want cellular capabilities to function properly, you will need the EXACT SAME model number Note 5. The cellular antennas are connected to the charge port. Each carrier Note 5 has a different has a different set of antenna. (i.e. You cannot put an AT&T board into a Verizon device and then attempt to access the AT&T network. The antenna accept different bands of signal.)
I am a former Cell Phone Repair Technician with an extensive amount of experience. If you have any other questions, message me.
Thanks for all the info and replies.
Knowing that this will work, I'm going to search for another note5 on ebay that is beat up. I'll place my motherboard into it and try and get the files off.
Watched some youtube videos and while it looks fairly difficult I think i can do it. Will post results.

Ok guys, need some help here....
Got a HTC TyTN II.... Worked great for like 8-10 months, then started having issues with the screen.
Sometimes when brining it out of sleep, the colors are all jagged, and the screen is out of sync and staticky (kind of when you have a VGA monitor and you half pull the cable out of the connector)...
So I'm assuming its a problem with the ribbon cable coming loose (if thats how its connected).
Another thing too, the memory card slot doesn't work anymore. This just re-inserts the fact the ribbon cable or whatever for the front of the device is loose.
Does ANYONE know how to fix this? Unfortunately I tried to rip the phone appart myself and voided the warranty...
Anyone else have these problems?
Sometimes the screen works, sometimes I have to put it back to sleep, wait 5 minutes, and wiggle the front. hit the power button and it works. This has happened across 3 firmware updates so it's hardware for sure....
It does sound like a piece of hardware is loose. The fact that your mem card is not working further suggests this. I took apart my Tilt yesterday to replace the screen which no longer responded to touch, although it still worked with hardkeys. As part of the process I noticed the mem card slot was integral to the screen components. In other words, the screen and attached component, including the mem card slot is loose. For video as to how to pull apart your phone, go here. I have never done this before and this video worked beautifully. Also, search the forums for the HTC Service Manual and go through this page by page, step by step matching it against this video (if yo have dual screens even better) and you will come out fine. I did!

You can buy replacement screens and the tools from the same website. Otherwise try eBay, which is what I did. Definitely get yourself a strong pry tool. The one I bought from eBay disintegrated in the first couple of minutes. Luckily there was just enough of tip of the pry tool for me to use brute force to pry open the case without damaging the phone.
thnx bud, ill be posting my results.
I bought this G1 with a cracked screen and I decided to replace the screen, however when I removed a certain part in the phone I managed to rip a ribbon cable. I searched for a replacement part and found out that it will cost about $185 to replace it. Now I am about to buy this other G1 for $50 that had water damage that I will be using for parts. But before I buy it, is there a way I can see whats wrong with it using adb? I'm interested in whether the part that I need is in working condition.
the phones condition is:
-the screen does not show anything but a backlight
-leds work
-rebooting using three buttons work
-lcd is probably screwed up because when i hit the power button i see part of the home background and then it fades away.
-no g1 screen logo while rebooting
-normally vibrates once while rebooting
-android os boots up
-"adb kill-server adb devices" doesn't list me any devices when i hook it up to usb. maybe debugging is turned off.
here is a link to the part i am about to remove
http://www.cellphone-repair-shop.co...icrophone-and-sd-card-slot_50H10000-02M-A.htm
the pcb board has the trackball, usb port, simcard slot, sdcard slot, and various other peripherals.

you ARE SO FUNNY!!!
Why? can I laugh too?
I don't see you turning a profit considering u can buy one for $200 on craigslist easy
its funny cuz its like you trying to buy a coumputer without a mother board. this is the main thing in the g1 it would be cheaper to buy the phone brand new
i have two, one of them needs this part and the other one has the part i need. and plus im fixing it for my brother.
G1 #1
-already Bought for $74
-needs pcb board
G1 #2
-$50 as is
-has pcb board
-has water damage
anyhow I managed to get into recovery and did a wipe logged in but once the screen turns off i cant turn it on anymore. would you say it is safe to exchange these parts?
Wrong Forum, goodness
how is it wrong..I'm not asking anybody to take it apart and do it for me. if it was in the wrong place would it be because I'm not developing something for someone to use. is there a section for modding, taking apart the g1 and internals. if i could develop something i would. i guess there's no help in posting useless remarks because that doesn't contribute to nothing. If this so happens to be in the wrong forum well then this is my first mod now isn't it? and since you went of of your way to tell me its the wrong place why don't you be helpful to lead your fellow xda forum member. ok.
accessory forum This seems to strictly be about discussing the SOFTWARE for the Dream. Accessory forum covers mods and replacements (to my knowledge)
$50 for a water damaged G1? WTF? Are you serious?

I'd say expensive, as you have no idea the extent of the water damage. If the phone was on while dropped into the water, the mainboard is likely dead. Buying it would be a waste.
Also, this forum is for software development. Moving this thread. Thanks!
hey thanks for moving my thread. as i reread my post it seems more of a question than a developmental thread.
further testing
i booted up
ran through all of the radios wifi, 2g, 3g, orientation sensor, made a call and they all seem to work fine. the one problem with this phone is that if i turn off the screen it won't turn back on.i think that maybe the pcb board might be salvageable. would that be worth doing?
What cable was it that you ripped? What was it connecting? And is it possible for you to take pictures?
my digi cam isnt working but this will do. its like a 1/8" rip on the side of the ribbon i was thinking about repairing but i cant because the ribbon is soldered to the board. i figure that i should try swapping it out, what could possibly go wrong? im assuming that the lcd has lost the ability to regain power after turning off from the water. and maybe...possibly the main pcb has dried up and not been damaged considering most things work fine. thanks for sticking around.
I'm not liking your chances of getting this working, but fwiw here's the service manual:
http://mikechannon.net/PDF Manuals/HTC Dream SM (A04).pdf
Thanks I already have that manual printed out. Took it all apart like4 or 5 times. its pretty easy to do. I'll be starting operation on it tonight.
I have a question regarding the changing process of the G1 motherboard.
I bricked my device by flashing a SPL, so it does not go past the G1 screen. Now i bought another G1 with a damaged touchscreen (screen works, but doesnt recognise the fingers) and want to use the working mainboard to insert into my G1.
Is there something I have to pay attenton to like some software barrier or something like that?
My plan was to only use the mainboard and keep my UMTS/GSM and GPS modules. Will this work? Where is the baseband stored at, on the mainboard, or on the GSM module?
Thanks.
Unless it uses different frequencies, might be easier to just swap the screen.
I've read the TechManual and its easier to swap the mainboard.
when you take it apart, remove the camera, IMEI Plate, and motherbaord as one piece. Transplant that as a whole, that way the IMEI is correct for the board, and the camera connection will not get fubar'd as they often do. Everything is on the mainboard, the other modules are just modules- the phone will run without them. BE CAREFUL not to pinch a coax cable when putting back together!
MUCH easier to swap the board, the disassembly beyond the motherboard is a PITA. I have been there, done that...it is a long process with many chaces for screwing up a cable.
What do you mean by the "IMEI Plate"?
the black sticker plate that carries all the imei and other important data that you see when you take the battery out
It is double side taped on loosely, gently lift the camera module and it will lift with the ribbon as an assembly

Hello, Today I will show you how to replace a problematic sim/microsd/volume/power. The reason why they can be fixed together is because they are all on the same PCB that we will be replacing.
I made this guide because I went snowboarding and I dropped my phone in the snow. I tried the rice trick but after that my power button was still dying. I looked up prices for getting a professional to replace it and it was around $60 for a part that costs $10 MAX. So i just bought the part off of ebay and documented my process
EDIT: if the pictures don't show up, just right click and open in new tab for now
EDIT: There is now no need to remove the motherboard to solve this issue

New "easy" method
6) You DO NOT need to remove all the connectors, only the ones in red
https://www.dropbox.com/s/5cgxcq2ocm7fkwi/IMG_20140414_151844 - Copy.jpg
Take note that the electronic above the sim card slot just needs to be peeled off gently, It is NOT a connector but it does rest on top of the PCB.
Also, you'll need to pry off the vibration motor (the circle to the right of the Sim card slot) as it is glued in
7) This is what the PCB looks like when separated from the motherboard
Note: your motherboard will still be in your phone, i just wanted to shop you what both parts look like
https://www.dropbox.com/s/6ysyid9eu2v5jjw/IMG_20140414_152536.jpg
8) Get out your new PCB
https://www.dropbox.com/s/6130c74hcx...414_152619.jpg
If The PCB you ordered did not come with the shielding then follow these steps
Note: Your motherboard should still be in your phone
8.a) Remove the shielding from the back of the original PCB, be careful of the glue to not damage any components

https://www.dropbox.com/s/v0oyeoaswkd0gb9/IMG_20140414_153602.jpg
10) Now carefully slide in the power and volume buttons into their correct spots
(I used the flathead the push the rockers out of the way to slide in the buttons)
https://www.dropbox.com/s/l94dfverf2ziwl7/IMG_20140414_153832.jpg
Now test the feel of the buttons before putting the Screw back in. (You should hear the tactile feedback)
11) Screw in the screw you removed to get the motherboard out
https://www.dropbox.com/s/3dw6lf5rtqsslut/IMG_20140414_153856.jpg
12) Put the cover back on (do NOT put the screws back in yet) and see if the all the sides close properly

Time to backtrack and see what is not seated properly
14) After all that is done and is properly fitted, Put in your sim car, micro sd, and battery
(Do NOT put in the screws yet)
https://www.dropbox.com/s/it26v6h7763flzs/IMG_20140414_154143.jpg
15) Now power on and see if it works
https://www.dropbox.com/s/fumzxsuewnqqgn4/IMG_20140414_154158.jpg
(Mine did, I was so happy I could cry!)
16) After it power on, test all your buttons
17)Test Cases:
Press power button once to see if the screen turns off
Press the power button to see if the Screen wakes up
Press the volume up to see if the volume increases
Press the volume down to see if the volume decreases
Check your sim connectivity, should have bars
Check your micro sd card by going to Setting>Storage>SD Card
Check your cameras
check your sound
If something does not work, backtrack and check all of your connections.
If your power or volume buttons don't work, check the PCB connection. If it still doesn't work, you might have received a defective PCB like I did (My volume buttons didn't work). Contact your seller and ask for a replacement for your defective item (I got mine for free and now everything works).
18) If everything works, NOW screw in your remaining screws and close her up and enjoy your day!

No do not yank it, the wires are sensitive, I used a soldering iron and heated the contacts up enough to the point where the wires were able to be pulled out. Then I soldered it to my new one. (Remember which wire goes to which contact)

Awesome walkthrough.
I might use it one of these days as my power button is pretty much gone.
Thank you. I'm having weird SIM card reading issues. Flash the same ROM twice, and once it will detect the SIM, the other time it won't.

That doesn't mean anything is broken.
Try flashing a stock ROM and if it works then your sim tray is still working
sent from my amazingly awesome OnePlus One
Don't forget to hit thanks!
So if I flash SlimKat 8.9 which I know the SIM card would read on before, and now it doesn't that doesn't mean it's a hardware thing?
Also, no custom ROM will now read the SIM. I've tried probably 5 since it started not reading. I'll try the stock ROM before I tear into it, I guess, but it seemed logical to me. IDK.
Radio is extremely crappy on this device. Custom roms don't implement all stock radio features so there can be (even randomly) broken things.
Hmm. Well, I tried to go back to stock. It just won't. Even got to a point where the LG update tool would flash in and out of being connected to the phone, and it would never settle on one or the other, so it can't do anything. Flash tool also reports no connection to the phone no matter what I do. I'm just about sick of this thing.

Probably a silly question but have you tried a different SIM card in the reader to see if it could be the SIM card itself that is a problem?

I agree that soldering is indeed a useful skill but I am not sure that a relatively expensive (and I am sure in everyone's eyes, precious) phone is the best place to start practicing; heat damage from a soldering iron can do irreversible damage to sensitive components as well as the copper tracks on the PCB.
Also, I may be a good idea to edit the guide a little to mention the possibility of needing to desolder/solder if the appropriate parts require it?
Yes, tried multiple SIM cards. None work on a custom ROM now. My first flash with SlimKat 8.9, was golden in every way but the camera. Then nothing but trouble with everything else. Even the "stable" CM 10 wasn't stable for me. I just managed to get a pure LG 20d ROM installed, and everything works fine. Battery life is even great. I started flashing custom ROMs to get a better device, but now with a rooted, Xposed, and stable stock ROM, I kind of wonder if it's worth bothering. It would be nice to have KK, but I don't really miss it TBH. I still have root, I still have "most" of what I liked about KK, and there are no more bugs.
Same with my original Nexus 7. Both had been flashed to KK of one sort or another (MANY times before I gave up), and both developed issues from it no matter how I did it. Went back to stock JB on both devices, and everything is fine.
If I flash any more custom ROMs I'm def going to keep a solid JB backup ready to get a stable device back if need be, and so far need be indeed.
Hello,
My LG Phone on KK stopped reading my SIMs a month or so back. I tried different SIMS, but still wont work. I flashed KK again and then later Lollipop AOSP, but still wont work. I thought maybe the SIM Reader was faulty, so ordered a new one. But even after changing, same problem. Don't know what the issue is. Can anyone suggest any further solutions / ideas ? Thanks.

If I want to repair only power only button that has became defective and doesn't respond well I have to do all these steps?? OMG
Is this the right component to purchase to fix power switch? (see attachment)
Hi
I have the c5502 with the bluetooth/wifi problem , the repair service told me they can fix it with bridges or smth and the problem will appear again,
First i dont believe them that much i just feel that they wanted me to pay for a new PCB
Question: Is this problem really fixable or should i buy a new one
Someone told me he will reweld the wifi and it is fixed
Note: The problem was temporarly fixed when i press hard on the back next to mic 2, but no longer works
Judging by your description, it might be that the WiFi/BT chip isn't attached well - some of the balls in the BGA (Ball Grid Array, look it up) have cracks that prevent proper contact.
If this is indeed the case, it can be fixed by reflowing or just directed heating of the chip area to the melting temperature of the soldering alloy.
However, this might not be the problem - and if it isn't, there might be a host of reasons for it.
You need to correlate the location of the WiFi/BT chip and the pressure you're applying.

Judging by your description, it might be that the WiFi/BT chip isn't attached well - some of the balls in the BGA (Ball Grid Array, look it up) have cracks that prevent proper contact.

Hi
I have the c5502 with the bluetooth/wifi problem , the repair service told me they can fix it with bridges or smth and the problem will appear again,
First i dont believe them that much i just feel that they wanted me to pay for a new PCB
Question: Is this problem really fixable or should i buy a new one
Someone told me he will reweld the wifi and it is fixed
Note: The problem was temporarly fixed when i press hard on the back next to mic 2, but no longer works

I have fixed my WiFi but bluetooth is still dead.
The WiFi problem is actually a poor connection between two boards inside the phone. There's two boards that need to make contact but because they aren't hard-wired together they rely on a touch contact. There's a shiny foil square on top board (main pcb) that has to contact conductive square on lower board. The shiny foil square looks like it gets compressed over time which is why the wifi only fails on some phones after a while. Some phones will be fine but I think it's just poor engineering to rely on a soft touch contact!!
When you push in the back against the mic you are pushing the boards together to make contact.
I fixed by placing some of the screen adhesive (which I had plenty of after removing screen) underneath the spacer pad that is under the bottom board. This forces the boards together and keeps the WiFi going.
However, I thought this would fix bluetooth but no such luck. Perhaps there's another connection that's not right somewhere?
so i sent it to a repair center sony told me the board is fried, i dont know what this means , everything works except for wifi bluetooth, they are both working until now, i think they heated the wifi part on the board

Hi,
Can you please let me know that how did you open that phone? did you opened it by your self?
Is it possible to open from back side only?
Do you have pictures for wifi solution which you described above?

Hi sorry but don't have phone any more. Don't think I have pictures any more either.
You cannot open from back side only. You have to take off screen. Look on youtube to see how it's done.

Yes, you'll need the screen adhesive stuff. Can find on eBay or Aliexpress or Witrigs etc.

old thread but just in case some zr user are still searching for an answer
there is a chip on main pcb which controls wifi and bluetooth, but sony didn't soldered it correctly and thus it needs pressure to make connections with pcb.
Only permanent solution is to apply heat on that chip ( after disassembling pcb from phone ) and then it will work for forever.
My phone's ( zr ) wifi bluetooth and nfc wasn't working, so i dissembled it and took the pcb to a laptop repair shop and told them to apply heat on that chip to solder it correctly ( as i don't have that instrument which is used to apply heat on small point ), and after that it is working without any issue. :highfive:
Note:- be carefull while removing screen as it is very fragile and will brake easily if not handled correctly ( yes i broke my screen and using an after market now which costed me Rs1800 ( for full folder ), i was lucky to still find its screen .
