Motherboard change... howto? - Galaxy Note II Q&A, Help & Troubleshooting

I have a SDS n7100 and need to change the mobo.
Anybody done this?
Anything spesial to think about when doing this (apart from ESD)?
Wath programing is on a brand new sammy mobo?
IMEI/SN?

Nobody?
Is a new motherboard from Samsung ready for odin?

On youtube there are loads of videos with regards to dissambling the phone etc. Its not that hard to get the main pca assy. Out and replace it. If you have a full nand backup you can tey restore it.

Thanks, currently they're out of stock, I'm not in any rush, ordered a Nexus 4 to replace it. Looks like this is what I'm going to have to do. Never importing a phone again. I've learned my lesson. Effectively there's no warranty.

They have been out of stock since they sold the last mobo to me....
Better send them a email and ask...

looking for a replacement mobo
Where did you order it from? Did it work ? I had also a bad emmc chip. Ordered the emcc chip from China. But the emmc chip replacement failed due to glue + damaged routes. How much the motherboard cost you ?
coming from here http://forum.xda-developers.com/showthread.php?t=2661269 many people are facing emmc failures , mine failed 2 months after the warranty expired
Thank you

Hi
I ordered my mobo from rounded.com, I payed 250€. It turned out to be a used part but works grate to this day (the new mobo also have affected emmc, but no symptoms) In daily use, as my secondary phone.
Best Regards

250 is too much for a motherboard
That is expensive ! I can buy new Note 10.1 for that price. It's more than 2y old tablet...

agreed
Yes! This was 1,5 year ago, the phone was newer
But the price today is lower... 113€.... If you see at the www
If you by a used phone, with cracked display... that may be even a cheaper solution

Warranty when screen broke?

Hi guys,
I've had a Galaxy Nexus for a very long time now and have been very happy with it. These days however, a very annoying charging problem appeared on my Galaxy Nexus. Basically, the device doesn't 'recognize' if it's charging or not. You can read more about the problem here: http://forum.xda-developers.com/showthread.php?t=1427539
Now I want to fix my Galaxy Nexus under warranty, because that's the safest way and I don't want to invest any money in it anymore since I plan on buying the new Nexus when it comes out. Problem is, my Galaxy Nexus' screen broke a few weeks ago (For the people who are wondering how; phone fell on the ground and then a biker rode over it...) and I'm not sure if Samsung will fix my phone under warranty since I'm 99% sure it's a hardware issue and it COULD have been from the drop which broke my screen (which I'm 100% sure it's not, because I had the same problem some months ago, but it promptly disappeared and just a few days ago, which means it was a few weeks after the drop, the problem came back.)
Anyone here can tell me what Samsung's and my rights are and if they will fix it? I'm currently visiting family in China, so if I'm not sure if Samsung's going to fix it, I can probably let it fix in China for cheaper, but that's not my preferred option, since it will officially break my warranty (and still costs money of course ).
Anyone? There must be someone who has some experience in warranties... ?
Is the glass cracked?
Warranties cover problems/defects from normal use. If they see the broken glass they will tell you that the problem was caused by an accident or drop which is not their fault.
you may get lucky and they could replace it, but its their decision.

Yes, the glass is broken. So basically, you'd recommend me to let it repair for cheap in China? Thanks for your answer by the way!
Screen replacements aren't cheap either..$100-$150 at least

You should get quotes from a few places before repairing, If someone offers to replace it WAY cheap than the others it may be a poor quality screen they're using. The most expensive one will be samsung though. ( I supposed since its OEM)
I know screen replacements aren't cheap, I've done my research. The problem is that the glass is linked to the whole screen which means you've basically got to replace half of your phone just for the glass. The cheapest I've found for a repair is about 190 euro.
But that's NOT what I meant. Because it's so expensive I've decided to not repair the screen and wait for the new Nexus phone. I can live a few months with a broken screen. I can't live with this charging issue however so I just want to fix the mini USB port. I got my contacts in China, so bad quality isn't a problem.
So basically I got two options:
1. Let the USB port fix in China for cheap
2. Let the USB port fix by Samsung in Europe (where I live) under warranty, but have a chance to be denied thanks to the broken screen.
And you guys recommend me to do the first one right?

I don't know how comfortable you feel about getting it repaired in China, but if you really trust your contacts, then get both of them done there. Since you said that you are going to get the new Nexus when it comes out, you really don't have anything to lose.
I do have trusts in my contacts in China. Just wasn't sure if I should do it because I will probably lose my warranty and it costs money. But I've decided: I'm hoping to let it repair in China, thank you! (Only the USB port btw, not screen).
They will likely deny your claim for a warranty replacement and tell you that it was probably just damaged when it fell. Unless you can actually prove to a rep that the issue happened before the drop. Even so, cracked glass generally voids your warranty as user inflicted abuse. Factory warranty generally only covers problems cause by the makers of the device. Anything else and the warranty is voided and the claim dismissed.
Source: I dropped my last Samsung phone. Cracked glass, bad radio. Was going to be warranty replaced, until I dropped it. They had on file my claim for the bad radio, but since the screen cracked after the fact they told me that voided the warranty and they absolutely would not honor the replacement. I had to pay an insurance deductible and get it replaced for $99USD.

[Q] N7105 Replacement Motherboard?

Howdy all<
First, I swear I've searched high and low for this answer. I've been to the xda threads with guides to disassembly and reassembly and followed the links to OEM part retailers and come up with zilch.
So, I have a bricked GT-N7105 with suspected sudden death syndrome. It acted screwy for a few days with random reboots etc and then, one day, I took it out of my pocket and it was dead. No boot, no charge, no lights, no nothing. I sent it to Samsung who (classic) are claiming liquid damage and want to charge me $588 Australian to fix it. I am unprepared to pay this. I know that the chip should be covered by extended warranty but this is voided by the supposed liquid damage. I will fight them on it but am not optimistic about the outcome.
So, assuming that I'm not giving my money to Samsung or the company that they outsource their repairs to, can anyone point me towards a link for a store selling replacement motherboards for the N7105?
Furthermore, I haven't managed to find specific information on the motherboard model number for the N7105: is it the same as the N7100 or any of the other Note II variants? Anything that can widen my search criteria will be helpful.
Thanks all. Love your work.:good:
Anyone?

try ebay?
If your phone has suffered SDS,then only emmc is damaged,not the whole motherboard.You can get it(emmc) replaced from a third party repair shop.
Gud luck.
1st of all, a motherboard is about 200-250$, and you can repair it at a normal smartphone repair shop, screw samsung.
request photos of the "liquid damage"
i'd take this to the court.
When i destroyed the partitions on my old galaxy player 5.0, they said it was corrosion from some sticky liquid lol, and they eventually gave me a replacement (probably because i figured out they were lying)
+1,Its the same old story they tell to everyone...here in india too .So if you are sure that its not damaged by liquid,just stick to your point and be stern in your approach while dealing with these so called 'technicians'...
Gud luck.

there you go http://www.etradesupply.com/samsung/galaxy-models/samsung-note-ii-lte-n7105.html?limit=all
N7105 is totally different to the N7100 internally so the mainboard will not physically fit onto the chassis if you put the wrong one in ..as the chassis behind the screen which carries the mainboard is totally different ... so get the the correct one if you are going to change the mainboard

[Q] Should I replace eMMC for GNex?

So I have a GNex which is semi alive... the last time I flash a custom ROM over it, it went into this weird mode where I couldn't update or revert the ROM/Kernel. I've found a website called www.parts4repair.com which has the eMMC and it's relatively cheap... less than USD$30. But I'll need to send the device in to a shop to replace it which may cost a bit more about another USD$30. Is it worth the fix?

For 60$, maybe you would be better off with replacing the entire motherboard if you can find one. It wouldn't be a new eMMC, but at least you would know you have genuine parts.
I can't Seem to find a replacement motherboard. But I get what you mean. That said, I can't get spare parts locally here in Malaysia for the GNex i9250. Where'd you suggest aside from ebay?

[Q] Soft Bricked Note2 N7105

I've searched around Google but couldn't find any solution that can fix my issue. My phone was fine before the night and the next morning I woke up the screen just stuck at the Samsung Note II N7105 for forever and plugging it into the charger would show up the empty battery meter.
I've tried flashing the stock ROM with Odin but it always fails after the NAND Write Start.
I've also tried flashing the recovery but it didn't work either.
I can still enter download / recovery mode on my phone.
Entering recovery mode would show a bunch of E:/Cant mount .... etc
I've already tried Wipe data/factory reset and wipe cache partition and that E:/Cant mount.. always appear.
Any knows how to fix this? If else I'll just visit the repair shop.
probably SDS
if you can't flash, then for 99% you have faulty emmc

Around 2 years+
Do you know how much it would usually cost to replace the chip then?

when I was buying my note 2 2 years ago I read about sane and insane emmc, so it's almost 100% that you have faulty emmc.
The chip can be bought for around 15$ + work it shouldn't be so expensive outside Samsung authorised service.

seems like it's not really expensive to fix that . Was thinking whether I should get a new phone or just repair this.

broke capacitive button cable

Hey guys, my phone got slammed in a car door and I finally paid £130 and replaced the screen because it got damaged to the point of being unusable but in the process of replacing it I accidently broke the ribbon for the multitask button. I've tried searching for the part on eBay etc and can't find a replacement part, could someone link me please? If it's available. Thanks in advance

Dunno, not much parts for the OP3. Have you watched JerryRigEverything? He has a really nice disassembly video.
Confirmed, you DID f**k up.
There are NO official replacement parts available online because OnePlus does not sell them to third parties. Anything you may come across is not official - including that screen you got somewhere.
Even if you don't mind unofficial parts, it's really hard to get small single parts for devices with poor service support. Full screen assemblies are fairly common, pretty much anything else isn't.
BTW, screen replacement in official service center costs about as much as you paid for the screen. Didn't benefit at all doing it alone ...
Don't have many options now, go check aliexpress, dealextreme and similar sites if you find anything. If not, well, ... you'll have to shell out even more £££.
