[DISC] Changing motherboards between different models

Hey everyone,
recently my SC-02h (Jap Docomo version) hard-bricked and has no way to recover besides JTAG or motherboard replacement.
This made me think of an experiment.
Can you replace any motherboard (which includes all chips and the storage) with another.
I ordered the g935FD dual sim version with the Exynos chip, this compared to my QC single sim version which is currently bricked.
Hopefully within the next few days I'll receive the motherboard and start the replacement process (I will probable film it) to see if it works.
If so, anyone could replace their motherboard by a new one that is unlocked or has a different chipset.
Please discuss here if you're also interested in changing your own mobo with another.

Can't see why it won't work as the motherboard is what determines the model. Just make sure you order up a dual SIM tray too.

Motherboards from different chipsets *may* have different connections on how things wire up. I'm not saying they do, I'm just thinking out loud. I'd only buy a replacement motherboard from the same variant.
And good luck finding a new motherboard. At the price they sell for, you'd be better off buying a whole new phone.

Would like to see how this goes. Please record the process.

Yea I ordered that one, although I thought the tray looks the same (bottom part), so until my new one arrives I'll use the older one.

I checked the connections and they are the same, the only thing that differs is the sim holder and the chipset.
Also a new phone (unlocked) costs at least 2,5times more (live in Japan).

I'll record it on video as soon as it arrives, also the process of taking it out and replacing it completely. So if it ends up in failure you can all see it.

In what way is it bricked? The S7 is almost impossible to brick.

Hmm I flashed a rom with TWRP, (lineage, but wrong build) after that I rebooted and the phone stopped responding completely.
So black screen, no led when charging, no response at all when pressing buttons.
Even disconnecting battery and reconnecting didn't work.
Also no recognition in windows when connected to USB

Well if I could I wouldn't be ordering a new MoBo
Even made a USB JIG

Another thing you might lose is waterproofness. I cracked my screen badly and instead of repairing it at a 3rd party shop, I sold it and got a new one. Coz it won't be waterproof anymore..

i should be fine, just get it glued back together properly.
besides i don't really care about it.

Unless the other components (camera, vibrator motor, various sensors, OLED Panel etc.) don't differ in the way they talk to the mainboard, I don't see why it shouldn't work. As others have said, I'd really love to see how it'll work out for you. So, thanks for sharing =)

Well it didn't work out, I put in the new motherboard but the phone didn't power on at all. There is also no led when trying to charge it. I'll be sending it back to the supplier and buy another version instead.

Was interesting to watch, however you only tried powering on twice and quit?
Connecting a charger had no effect?
Unless the board your received was dead to begin with.

Can you share the link of where you bought the motherboard? It might be that you bought a blank motherboard. In that case you want it to be flashed with the correct IMEI and partition (table?). AFAIK the IMEI has to be that of your previous phone since you can't just "create" a new IMEI. Don't even want to get into the legal repercussions but here's a sneak peak; in some countries it's a criminal offence to alter an IMEI or even have tools to alter IMEI. Don't quote me on this and I'm asking the community to correct me. If the motherboard comes from a previously active device, it should have its own IMEI and none of what I said before matters.
Whatever, none of that necessarily explain why it didn't boot up. Have you tried charging and plugging it to a PC? If it isn't dead, your PC should at least detect A device.

It should be one with an IMEI how else can it be unlocked.
I tried plugging it in as well, but my PC doesn't recognise it at all.
I've ordered a different one this time, this motherboard was also slightly different from the one I had (2 cables instead of 3) so it might be incompatible.
I ordered this one now: https://www.aliexpress.com/snapshot/0.html?orderId=82116420384467&productId=32737224430

Did you end up having any luck with the second motherboard?
Or has anyone else attempted this before?
I'm looking to swap my qc chip for the exynos.

How was the operation??
Hello i'm interested to know how was the experiment becouse i wanna try almost the same thing, i have a s7 sm935fd and i wanna change the motherboard for a sm935f model. Please answer me!

I am also going to try swapping motherboards. How did yours work out?
Hi @totalvamp,
I am going to try swapping out a good motherboard from a banged up sprint G930P phone with a clean IMEI into a clean, whole, G930X demo model that I picked up cheap on Ebay.
The "X" demo phones work on WIFI only. I understand that the "X" motherboards are missing the cellular radios, which is why I am trying this swap -- it should be far easier and less costly than doing a full screen&LCD replacement, which requires tearing down the entire phone, and costs about $150. Hopefullly, I will just have to remove the back, the QI receiver and I think the camera, and I'll get access to the motherboard.
My hope is that all the rest of the parts are present -- we'll see how it goes.
I look forward to hearing from you.
Philip

Microphone and speaker no longer working

I have run into the dreaded headphone jack problem. The phone won't play audio through the speakers and doesn't use the microphone because it thinks that headphones are connected. I've tried resetting it to factory settings and it didn't fix anything which is why I think it's not a software problem.
After some Googling I found that I'm not the only one to have this problem and that Google is replacing the units with this hardware fault. Unfortunately I didn't buy the phone via play store so I can't return it directly to google.
I'd like to try and fix it myself. If anyone knows where I could buy a headphone jack for the 5" pixel I'd be very grateful. Before I buy the replacement part I was thinking of removing the headphone jack and trying to start the phone like without it. My reasoning is that the phone would then default to playing the sound through speakers and I would be sure that it's a headphone jack problem. Would that work at all or the phone won't even start?
I need your advice and opinions, thanks

Please keep us updated as I'm facing the same issue:/

I ordered a replacement headphone jack and as soon as it arrives, within the next 2 weeks I hope, I'll replace it and see if that gets it fixed.
A couple of more details:
-problems started about 3 days after updating to Oreo
-at the beginning the volume would first turn itself gradually down to zero and I had to fight it with the volume up (I would always lose eventually xD)
-there was usually a loud pop heard through the headphones after that 'battle' and then the audio and mic would completely cut off
-restarting the phone would enable the audio and mic again but the problems returned as soon as I plugged in the headphones again (tried with several different headphones)
-factory reset didn't fix it and after a couple of days of problems I'm now stuck with no audio at all and no mic input
-my phone can't recognize the headphones anymore

I have the exact struggle, restart will work for a while and then problem return, when I contacted google they offered a replacement but since I'm not in Canada at the moment, they will not be able to process my replacement request, but google representative told me that I can try and replace the mic with the charging port(as it all comes together) and it should fix the issue, but I also think that it might be the headphones jack, also this happened after I tried Android O beta.

I'm still waiting on the part to arrive. I'm expecting it within the next two weeks. I'll try to document the replacement with photos and/or video so others can do it if it turns out successful

Okay guys, here's the update with some good news and some bad news.
The replacement headphone jack arrived yesterday and the good news is that I replaced it and it seems to have fixed the problem! Yay!
But the bad news is that in the process I damaged the LCD screen so now I'm waiting on a replacement LCD. I guess I should've expected that because the screen and LCD itself are extremely sensitive and the damage is not even visible, but it's simply not working anymore.
So how do I know it actually works? Well since the phone used to be paired to my PC via bluetooth, whenever I turn on my PC a notification sounds on my phone if I want to pair or not.
Minor bad news - I tried to record the whole process as a tutorial for anyone who'll try to fix this themselves but my camera's battery died halfway and I lost everything I recorded.
Here are the 2 teardown videos I used for guidance: First and Second. I highly recommend you watch them entirely before attempting anything.
I got the headphone jack on eBay from here. It is totally overpriced but it's the only place I was able to find it.
I'm getting my replacement LCD and adhesive for it from Replace Base

I definitely recommend others try to get Google to replace it. I got mine from Swappa second hand and they still respected the warranty. Much easier and cheaper than replacing it yourself.

wow its nice to hear that it work, but some say that its the charging port board that has a problem(the location of the microphone). should i buy headphone jack replacement or charging port board?
yesterday i put i my pixel into freezer for 2 hour(i tried this because it help my previous phone which is nexus 5x come back to life for a while haha) and rebooted to safe mode and tried to record and microphone work, rebooted to normal and until now it still work, but im hoping that your replace method would be a permanent fix and i will do that too.
please update this thread again as soon as you replace your lcd
thank you

Another update. I got the replacement screen today but the problem hasn't been fixed. Well, partly it has been. The speaker now finally works when nothing is plugged in but the phone can't recognize any headphones. So, like Mattish13, if you can get it replaced by Google do so. Fixing things on my own is my hobby and was logical since I couldn't get mine replaced by Google, but this fix is not worth your time or money, trust me. I'm guessing the next thing to get replaced would be the daughterboard, maybe that would fix the problem finally, but in my opinion it's not worth it.
Ironic how so many problems with the headphone jack appeared for so many people and at the same time Google decided to ditch the jack for Pixel 2 :laugh:
Edit: just to be clear, since I already invested in a new screen and new jack, I will drop in another 25$ for the new daughterboard. If that doesn't fix it, nothing can

As strange as it sounds the freezer trick works! I think the issue appears when the phone heats or it's heat related

Yes, sorry for forgetting to post earlier. I changed the daughterboard and it appeared to be working perfectly. But about 30 minutes later the microphone again wasn't working and there was no audio. I was back at the beginning.
Then I did a factory reset and again it worked. But every time, after about 30 minutes it stops working. At this point I have no idea what the exact problem is.
I've definitely fixed it partly somehow because before I couldn't get the microphone and speaker to work at all. Now I can, but it fails after some time eventually. The headphones jack works normally until the failure happens.
I've tried the freezer trick after that and had no noticeable improvement. My theory now is that the problem probably was on the daughterboard but the replacement one I got (which is actually a refurbished part) might have had the same problem but not as serious as my original part.

Thanks for the update, interesting... Maybe the daughterboard is faulty as well, but didn't Google response was that there is a crack line in the audio codec, as far as I know the audio codec is on the motherboard, I guess this problem won't be fixed after all, it is really annoying!! I wanted to get another pixel maybe XL this time, I found some offers with used ones, but now I am really afraid to buy one and this problem appears with the second phone.

Yes, found that response but unfortunately changing the motherboard is not possible because I couldn't find any place that sells them and I guess it's the same as getting a new phone in the end ?
I ended up getting a pixel XL but Google said this problem appears on devices manufacturered before March 2017,so I made sure when I was buying that I got a device manufactured after that and I did. So far so good ?

Do you mean your phone had warranty till 2019 or all pixel devices, because when I contacted Google the guy on the phone told me my phone has warranty till Jan 2018, which sucks in my case as I'm at the moment outside of Canada and won't be returning till summer 2018

I believe all pixel devices because I bought mine just after they came out in Australia... Phone screen broke and when I replaced it I had these problems... Told Google it was a hassle contacting my australian provider and would cost alot and they said it had warranty until '19 and that they would replace it here in the states free of charge... It may have been only till '18 but my first pixel was faulty as well and I had it exchanged out there n straya so maybe that's why it is until 2019

Google Pixel Mic and Speakers not working

Hi, the speakers and microphone on my Google pixel do not work and I also noticed that video recording and the Google Assistant would refuse to work as well. My pixel also fails to recognise that a headphone has been connected to the the headphone jack. I got this phone second hand from someone but they told me they had factory reset the phone but the speakers and microphone would still not work so I think it is a hardware issue.
Help would be greatly appreciated thank you ?

It's a hardware defect affecting pixel devices produced before January 2017. It would eventually happen to the phones produced in 2016 and there's no way to tell when it would happen. Only fix is to change the motherboard. If you're able to return the phone then do it.

Unfortunatly I bought a second hand pixel and did not know this issue until I tried to use audio. I'm trying to repair it myself and I read in another forum that replacing the headphone jack or the mic/speakers would solve the problem. Do I need to buy another mother board and replace it with the current one I have right now?

I personally have not done any such procedure so would let someone else answer. What I could do is to identify when your phone was produced to narrow down if that could be the issue. If that's the same then the motherboard needs changing and you might just find a beaten up working pixel for cheap and try swapping the parts unless you find the motherboard for cheap though. Could go to settings>system>about phone>status>serial number. Give is the 5 first characters. Mine is FA77M. I could read from this that it's produced in taiwan on the 21st-07-2017.

From what I understand, all devices produced in January 2017 and after should have this issue fixed. Pixels made in 2016 is pretty much a ticking "bomb"... someday the issue will occur. I personally would stay away from the devices you mentioned. If you find a device with the third character being 7 then you should be safe. My device is FA77M which reads - Produced in Taiwan Taoyuan B factory - 2017-July-21st, which should be safe.

Thanks for that information mate. It's hard to find that version of yours though.

I have a november 2016 pixel and uBreakiFix (canada & US, but I did it through Canada) replaced the motherboard free of charge even 8 months outside of my warranty period.
I'd consider going to them.

Unfortunately I bought it second hand and I don't have the receipt ( I live in Sydney btw), so even if I did go to my local ubreakifix I don't know if they'll fix it for me.

Audio and microphone stopped working about 1 month ago.
It stopped working on Phone (the local Google app), WhatsApp, Skype & HangOuts.
I could still hear podcasts and music and YouTube. Though I did notice that bluetooth and wired headphones with microphones didn't appear to work.
I tried Safe Mode.
The issue still occurred.
I did a complete Factory reset of the phone.
The issue still occurred.
I have only installed the apps that I use constantly, which includes WhatsApp and Hangouts.
The issue still occurs with bluetooth and wired headphones.

What about this? I have same issues help me

Similar Issue, but I suspect MindTheGapps or Lineage Update
My sons Pixel has similar issues. It started around August.
During Calls he could listen but the mic did not work. Then in Whatsapp and Youtube app videos would not play, while the same videos from youtube played fine in the Browser app.
Usually after restart it works until Spotify crashes the phone, or at least Spotify was active while the phone crashed. Why comes MindTheGapps with pre-installed Spotify anyway? After install from Playstore there are two versions on the phone.
Sometimes after a hard phone crash, mic and speaker work for a while, also a short time after factory reset (until Spotify, Youtube and Whatsapp are reconfigured), then mic and speaker stop to work again. Sometimes the Speaker works for a longer period but the mic does not.
Sometimes there is a message that the system process has stopped responding and if I want to stop it or wait. After the next phone crash this message disappears.
Its hard to believe that this is a hardware issue, while the phone falls into the manufacturing dates of the reported motherboard issues.
Next thing I am going to try is to use OpenGapps and if that does not help, revert to Stock ROM. Maybe this resolves the issue.
Thanks.

Can't hear at call and No Sound at earphone jack

I have got a Pixel at relatively cheap price recently. Everything works perfectly except the there are problem at earpiece and earphone jack. I can't hear anything from the earpiece when using the build-in phone app or any other phone application. I originally think of hardware problem. But the strange thing is, if I play record message in whatsapp, I can hear the recording from the earpiece! I have tried some hardware testing app download from google play, some app crush when testing the earpiece while some could play sound with the earpiece. Another issue is there is no sound at the earphone jack. However, when I use the hardware testing, the earphone jack actually work! I have tried to contact google but since I am at a country without google playstore, they can offer no assistance. And they say they did not receive any similar report. Google just ask me to find some local workshop to fix it since I don't the warranty anyway. But if it is a problem with the motherboard, I don't think local workshop can fix without changing a new one. I have try some some of the custom Rom and kernel, but nothing works.
Does anyone have the same issue and got a solution to it?Or Maybe it is a hardware problem? I hear some people it is a manufacturing flaw on the motherboard.
Thanks.

I have the very same problem, again. My old Pixel got that bug and now my replacement as well. Makes me think, that it is Android Pie related.

Have you ever tried safe mode or done factory reset? I have encountered same issue, and got fixed by a local guy. please check my previous thread for more detailed info.

I have tried safe mode and done factory reset but still not working. Where did you find the guy and how he fix it?
I am currently using a Bluetooth headphone and it works alright.

The guy is in China.
After the earphone was fixed and last almost half a year, I got a new issue. I was traveling in Dubai, suddenly the phone became very hot and can not turn on screen. I had to long press the power key to turn it off.
After that, I never powered the phone on
Finally, I found another guy and got the phone fixed.
So, Damn google. I will never buy a pixel phone until it launches months later

Is anyone having the issue where your phone freezes/crashes/reboots whenever you use the phone dialer app.
I found lots of forums on this but no solution

This has been discussed almost everywhere. After lots of searching around, I think the only Fix is either Motherboard Replace or USB board replace. As USB board replace is cheaper, I ordered one (Will get it by end of this month). Should see whether it will make any difference :fingers-crossed:
If it doesn't,
Then either I will get a used cheap phone from 2017 and take out its motherboard or I will sell mine
