Signal Flex Cable and Used Motherboard Issues (DIY fixing) - Galaxy Note5 Q&A, Help & Troubleshooting

Greetings, I'm recently bought a used Motherboard around $90 bucks at ebay from China and shipped to Malaysia, for Samsung Note 5, but I made a horrible mistake during the disassembling process, that I tear out the signal flex cable of note 5 with the chip stucked inside (causing me unable to link the cable to the recently bought motherboard), so now I moved out both signal flex cable from the phone and hoping for motherboard and screen able to boot. However, the phone is not responding still though I replace the dead motherboard with the used motherboard. Is the signal flex capable really crucial for the phone booting? I hope I could get some advice from this platform.
Note that: I charged the phone with fully functional battery to test booting, and another attempt without battery but connecting to charger. But none of it gives me positive feedbacks.. Could this be a fake motherboard as well? or it just need signal flex cable to be connected for booting?
Thank You for any replies!

Note charging module

My charging port is broken and rather than desoldering the old port and fitting a new one I've decided to just replace the module. Does anyone know if the i717 and n7000 modules are identical or at least compatible?
I was just going through this problem myself. I have no idea why, but the color of your GN (Galaxy Note) matters! So I am sure that the difference in the N7000 and the i717 will be a huge problem. For instance, I have a white GN that wouldn't charge. I found and I ordered a charging port flex cable assembly. Now, mind you, the only problem with my phone was that it wouldn't charge. After installing the new charging port flex cable assembly, I could charge, BUT I didn't get any (and I mean zero) connectivity to the AT&T cellular network.
After hours and hours of assembling, un-assembling, seating cables, un-seating cables, scouring the net for any possible reason why this damn thing wouldn't work....I came across a post here on xda. In the thread, it mentioned that there is a DIFFERENCE between the charging flex cable assembly for a WHITE GN and a BLACK GN. Who in the world would have thought that the identical phone, other than the color, would have made that much of a difference?! That is why it never occurred to me to check that.
Unfortunately, the only seller that I have found, (for the WHITE GN) has been listed on back order since Feb of 2011.
So I am doing the next best thing....I have an external battery charger to charge my batteries, then swap them out when one goes dead. I'll do that until I can find the right charging port flex cable assembly that is going to work.
Hope this helps! I just didn't want you to go through what I have went through!

N910t "Unable to charge" message

Ok, I have been dealing with this issue and trouble shooting every which way but loose. I am getting this message every time I try to charge my phone. "Unable to charge your device, make sure you are using a samsung-compatable battery and charger, and that your device is properly connected to the charger." The device is almost 2 years old so it is out of warranty, I called samsung and sent it in at my own expense and they marked it "BER" (Beyond Economical repair) because I had rooted it, I didn't install my own rom I just simply tripped Knox so samsung refused to work on it. Very disappointing. I have now set out to fix it on my own.
OEM Battery: Check
OEM Charger: Check
Properly Plugged in: Check
I have tried multiple different fixes, factory reset didn't work, so I flashed Cyanogen 12.1, Rapture, and Dr. Keton ROMs to see if it was a software issue, NOPE. (P.S. Rapture is my favorite)
So I ordered a wireless charger so see if it was the charger port, NOPE.
Then I ordered a external battery charger and 2 other batteries so I could at least play around with it. SO I have determined it is not the Charger port, Software, or Bad Battery.
2 weeks Prior to this problem occurring the bluetooth flat out quit working. So I am now considering getting a new motherboard but this requires a lot of work I would rather not do if there are any other suggestion at this point I would love to hear them before I pull the trigger and buy a 150$ motherboard, If it honestly comes to that I might just sell the phone for parts, I bought an s7, but I loved my note 4. I would prefer to go back to it cause I like the battery life on the note 4 but LOVE the camera on the s7. Any way, Any Ideals would be fantastic, thanks.
I had an international note 3 that used to say that. I think you may have to use a power source for which that perticular phone was designed for.... just an idea... If i recall i could slowly charge it using a car charger but not a wall charger. I dont know why though i sold it on craigslist before i found the answer.
I also had a similar problem with a regular domestic note 3. Turns out my baby stuck my phone in her mouth and her spit corroded the terminals. So the phone just wouldnt charge. Was a pretty easy fix for like 10 bucks for a whole new charging port. Did you maybe drop your phone and dislocate the flex cable from your board? http://youtu.be/OYBWT1yfilc
Doesnt seem toooo difficult to fix but if it were me id just swap out batteries

[PROBLEM] Charging slowly (only USB charging) and PC can't recognized it

I have problem with my Nexus 6 (no warranty) from last two months. Phone is rooted and on 7.0 (from yesterday)
One night I noticed my phone says it is charging over USB when connected to the quick charger so it is charging very slowly (more than 8 hours from 0-100%).
I was using the Qualcomm quick charger and USB Magnetic adapter when it start to do only USB charge. I tried different "regular" chargers and multiple USB cords. All yield the same results. So it seems to be some faulty hardware but I don't know which part.
Also i noticed that PC has stopped recognize it when it's connected - it only show USB charging. I don't have option to set connection to MTP (alternative I found it in developer options - same result)
Already tried:
-different chargers
-different usb cables
-factory reset on marshmallow
-downloaded Nougat on phone and flashed to Nougat rom
I have friend who repair phones, gave it to him - he changed microusb connector - same problem...
I mean phone is working but I really depend on battery. I use it everyday for navigation and my company use Android application for work.
Any ideas?
I have some money to buy another phone but I don't want to change my beloved Nexus - I can't find an alternative phone to replace this beast.
Even i'm suffering from the same problem. (Out of warranty)
I sent it to 2 different repair centers of Motorola in India.
1 changed the port and still the problem persisted.
The other one was a more advanced service center. They took the phone for around 2 months and then they told me there is some hardware problem and it would cost around 60% of the device cost to repair the problem.
On asking the problem, they just kept telling there is some Hardware problem which they couldn't explain but they knew this would repair the device.
Now I'm a student. Somehow i bought a Nexus 6 that too when its prices were at peak (Rs. 48999) with my parents help.
I use it as my only primary gear. Now it takes around 7 hours to fully charge if kept on Airplane mode and that too without using it.
Its just a waste i am keeping because i cannot afford the repair and even cannot but a new Phone.
Choosing Motorola sucked! (I still trust Google and love it)
I saw TK using Nexus 6. I was much excited. I saw all his videos. It was fun but now even he has dumped the device.
Now i just keep on trying my luck on Giveaways by XDA expecting to get a device.
(I was too excited when they had a Pixel Giveaway by Rhinoshield but unfortunately i didn't win)
All my hope is XDA Giveaways coz i can only trust them.
If you find any solution to this problem please do reply here or mail me.
It would be of great help.

That magnetic Micro USB Adapter fried your N6 charging port. This happened to my N6. It exactly what you have described. Fortunately, I have warranty and Motolora sent a replacement unit. It beyond repair. The replacement units was fried again when I used the magnetic POS. So got another replacement. Stay away from that magnetic POS. The seller gave me a full refund without even asked me to return that magnetic POS.

my phone is wet, where can i get a motherboard?

HI there guys, That is my problem, I am from Chile, my rog phone 2 got wet, the USB charging pins are burned, the phone does not turn on.
Where can I quote a motherboard?
I have not yet brought the phone to the Asus support, but already told me that they only change the complete component so I think that a motherboard repair is unattainable for me
search aliexpress but can't find.
