[GUIDE] Replacing USB charger board (and other parts) - Galaxy S II General

I am writing this guide as this issue seems to be getting more and more common (and @MistahBungle and I have answered threads about this a number of times).
The following is supplied as information only....
If, having read this post, you feel confident to undertake the described processes, you do so AT YOUR OWN RISK. I will not be held accountable if you cause further damage to your phone by following the said processes........
This guide was originally written to cover replacement of the USB board, but the information and provided links also apply to replacing other parts. The advice given, broadly applies to whichever part you need to replace......
If a repair under warranty is available, I would always advise this as a first option......
If it is not.......read on...
The USB board is an important part of the phone. Without it we can't charge the phone.....or easily transfer data to or from the phone.....or flash new firmwares.....or recover the phone if things go bad. This board also has the microphone and aerial connector built on.
It stands to reason that a USB cable regularly being plugged in to/unplugged from the connector is going to wear it out.....fairly quickly.
For those who are technically competent (even just slightly) it is an easy and inexpensive part to replace.
In the link below, you can find a very useful and clearly explained video tutorial which shows a COMPLETE step by step disassembly of a Galaxy S2......
https://www.youtube.com/watch?v=65pvAINg2ME&feature=youtube_gdata_player
it will be invaluable to those who want to do this, but who are unsure about how to begin.
To do this, you will need.....
1) A set of fine 'jewellers' screwdrivers.
2) An old credit/store/loyalty card or guitar pick to help separate the case. (It doesn't matter which, as long as it's plastic).
3) A fine pair of tweezers to help pick up the screws.
For those who feel it would be an advantage to have it, below is a link where you can download a copy of the S2s service manual....
https://www.androidfilehost.com/?fid=24052804347838302
It could turn out to be useful for other repairs on this phone....
If, having read this post and watched the video, you don't feel confident to 'do it yourself', you will need to return your phone to unrooted stock in order to get a warranty repair with Samsung. Provided you currently have root access, you can use an app created by @Chainfire called Mobile Odin to flash the firmware and unroot. This is done 'in phone' and doesn't rely on the use of the USB port. See the thread below for details...
http://forum.xda-developers.com/showthread.php?t=1347899
So....now you've watched the video, and you're confident enough to begin.......Don't pick up that screwdriver just yet.......
As a FIRST resort, I'd recommend that you try to clean your existing USB port.........
Some people have mentioned simply blowing into the port can dislodge any dust and return the port to full functionality.
Others have said that gently using a toothbrush on it has had the same effect. You can try this dry or with medical alcohol (not 25 yr old whisky lol). If using alcohol, remove the battery first and allow to COMPLETELY dry before re inserting the battery and powering on.
Other people have commented that bending the connectors within the port has had the desired effect.....this last option is something that I DO NOT advise as unless you are REALLY careful, you could end up causing more damage.
If, having tried the first two options above, there is no difference, read on.......
As you know, there are several different variants of the S2 (over 20).....so it can be assumed that there will be different variants of the board too. I know for certain that there are FOUR different versions for the S2 international alone. ....
So how do you know which board to get for your phone?.......
Look at the pictures below.......

}
This board was taken from an international S2.....
Note the small white print in the second picture......
The critical print to look for on your board is the 'REV' number. On the international version it'll say REV1.5, 2.2, 2.3 or 2.4. On the other variants it'll say something else. Be advised, none of these boards are interchangeable, so you need to match this REV number with the one on the board you remove.
Now you can pick that screwdriver up....
It's time to replace the board.....
Just remember not to force anything.....be gentle....after all, you're pulling apart some very delicate micro electronics....
Provided you follow the advice in this thread and the linked video tutorial, you'll have a fully operational phone, and paid a fraction of the cost that you would have paid at a service centre......
Good luck and happy DIYing.
Some people have reported that after changing the board (even if they purchased the correct rev version) they suffered a loss/reduction of signal strength. This thread......
http://forum.xda-developers.com/showthread.php?t=1950114
offers a potential workaround. The evidence suggests that it seems to work, but there *may* be unforseen long term issues if this is done.....
In this final section I will list verified sellers of this part. Make sure to contact the seller in advance to ensure they can provide the correct 'REV' version. If anybody has good experience with any other seller, leave a comment/link in the thread and I will include it here..........
xtechonline on eBay (i9100 international boards)
http://pages.ebay.com/link/?nav=item.view&id=370797750646
The above seller lists all four versions of the international board.
This seller......
http://www.truesupplier.com/oem-sam...-port-charger-connector-replace-pr-29094.html
sells what he states are 'OEM' (Samsung original) parts, and it appears that he ships worldwide. Contact the seller before purchase to find out availability of the correct rev version........
This seller MobileExtra (on Amazon).....
http://www.amazon.co.uk/dp/B0098VPOK8/ref=cm_sw_r_udp_awd_8Hjotb1JF0Q2Z
doesn't state what rev versions he stocks, but he sells the board either on it's own, or with a screwdriver to help do the job.....but to be honest, if you've got as far as exposing the board itself, you won't need to buy the item AND screwdriver anyway.
As before, contact the seller to ensure you get the right part......
This seller.......
http://www.parts4repair.com/categories/Samsung-Repair-Parts/
seems to stock most parts that could be needed for the S2 and it's variants. From what I have read, the parts may be recycled (taken from other, used S2s), but having said that, repairing a phone with used parts is preferable to being stuck with a phone that doesn't work at all.....
Here are the results from a 'general' eBay search......
http://m.ebay.co.uk/sch/i.html?_nkw...flex+cable&sqp=galaxy+s2+i9100+usb+flex+cable
There are plenty of suppliers still (September 2015) As with anything you buy on ebay, do your research.....check supplier location, reviews etc before you buy!!!!
Also, it will help to include a 'note to the seller' informing them which rev number you need/are expecting to be delivered.
If you have any questions, or want to add anything, feel free to post a comment below........

Just to mention. Some boards I bought from eBay didn't work properly, such as you get no signal or it won't charge. I don't know why they do this but sometimes you get non working boards so if you do replace it and it doesn't work, don't assume it's a phone fault. You could have picked up a faulty board

Or.....purchasing a 'mis-matched' (wrong REV version) board can have these effects too as none of the boards are interchangeable........
(OP modified to reflect this)

Maybe you should have a look of the post/tutorial a guy made about using like 2/3 of a new board because his old board got better signal.
I.e pros and cons of changing the board,and fixes.

I'd appreciate a link to that thread if you can post it
Also the OP is there for people who have to replace the board because the original has become faulty/inoperable due to a worn out USB connector.....
Edit....thread located and linked in OP.....
Sent from my rooted, de bloated, stock JB powered S2 via PhilZ kernel and XDA developers app

Yes but if you read some of the other threads,they change it because of that problem,but other problems can arise
Eg
Mic and loss of signal
There is nothing new about your guide.But it would be different if you merged about 3 of them threads I mentioned together,which could cover everything in the one place.Also links of "proven" sellers of the part.
Otherwise whats the point of yet another guide.

As I mentioned in the OP, those problems probably arise because the incorrect board was purchased.....
I also pointed out what to look for when choosing the replacement board......that in itself makes this thread not so pointless......
I appreciate your input...your suggestions are valid.....the OP will evolve over time to include more information....that is why I requested you provide links to the threads you mention......
Sent from my rooted, de bloated, stock JB powered S2 via PhilZ kernel and XDA developers app

I am not making the guide Keith;you are supposed to be.The link about the video in your first post shows you created a thread about something you "just found";when actually it was posted a year before
http://forum.xda-developers.com/showthread.php?p=25438587
This thread will need to evolve,thats for sure.Im just advising you to try to get as much relevant information as you can and put it in this thread.
All the info is out there,as Ive read it,so if you want to help people get the info/links in this thread to cover everything,which saves them time if its all in the same place.
Once you have that sorted out,ask a mod to clean up this thread and get it stickied lol.

I have replaced the charging board last year.
A good and suitable screwdriver should be used for disassembling i9100. The screw is tiny and it's easy to get stripped (It's my own experience).

Agreed....good point.....
Something like a jewellers screwdriver.....
Sets of these are available fairly cheaply at most good DIY stores......

Nice one keith, keep it up!
Sent from...this is not even my S2

just searched and came across this thread after picking up another i9110t that was faulty, to use the screen to fix my i9100t cheaper than fitting a new screen
I removed the main board from my phone with the cracked screen and fitted it to the faulty I9100t and it fired up. but no signal from my carrier (don't have the best reception at home tho). was able to get reception and receive a call in another location with better reception but still not a good signal. charging fine and everything else seems to be OK
so today i removed the back thinking the antenna wire might not of connected properly where it clips on the main board, but all looked good. thats when i looked at the usb boards and compared the boards and part numbers and found differences. both phones are the same model number tho . so seems like there is also a difference in board numbers also with the i9100t one being a Telstra (Australia) phone with usb board number GT-I9100 REV2.2 and the other Vodaphone (Australia) Phone with GT-i9100 REV0.4 usb board
so im hoping i can gently remove the usb board gently without damaging it and swap it over.
wish me luck:fingers-crossed:

I hope swapping the USB boards from one phone to the other works for you......though I have a nasty feeling that it won't be that simple......
The main boards could be different too......

When I linked this to my guide, I never thought I may need it myself... My phone says it's charging even when nothing is plugged in :/ I've yet to clean the USB port as I'm out, but I may have to end up replacing my usb board.
Just wondering though, is it bad for me to keep using my phone while it 'thinks' it's charging? Currently I have the battery out of the phone just in case.

I don't *think* it'll cause any long term harm....though having said that, try and examine the contacts in the port with a magnifying glass to see if there are any obvious shorts.......
My wife's S2 had issues for nearly three weeks before I changed the board.....there are any number of reasons why the port fails, so you need to assess the possible reasons for the failure and decide what is best for your phone......
Sorry I can't be any more specific than this, but without examining your phone, I don't know what the underlying cause is........

8525 shuts itself off!

I have a 8525 that is 14 months old and has been working wonderfully all this time. A few days ago it started to shut itself off at no repeatable times. I pull it out and it is off! I try to load something and it shuts down instead. Today I did a total wipe and reinstalled from a back up. The same problem occurred. I wiped it again and installed a 2 month old backup and the same thing occurred. I have changed the battery. The memory is fine. The only thing that I have not tried is a wipe and a reinstall from scratch, but obviously would prefer not to do that.
WM 6.1 is running
Check to see if your battery connection isn't lose. If the power keeps shutting off for no reason in your pocket it could be that its not making proper connection. If you bought another battery that wasn't a HTC original then it may not be Quite the right size. I had this problem with an extended battery I bought. It was about 1/2mm less width than an original but that was enough to be a problem. A piece of paper between the battery and the casing fixed this.
Cheers...
not the problem
Thanks, but the battery is not the problem as the spare battery is one that I have been using for 6 months and the other one that I tried is the factory battery. Unfortunately, it is more serious than this.
I'm having similar problems with my Hermes...and I bought it ~14months ago too, refurbished, it's a Voda v1605, uk ebay seller.
Actually mine stays powered most of the time and it's not a SW problem: I'm trying various ROMs and I'm 100% sure the problem is HW-based.
Well it's much I have this prob and don't have any warranty, so I opened it and tried to "manually" solve this matter: I put a page between my qwerty and the motherboard, and this, together with some paper under the battery, solved the problem at most.
Now it switches off less frequently, but still not enough to safely bring it in my pocket and always find it switched on after taking it off
I tried to get it repaired but they told me they'd change the motherboard for +/- the price of a "as-new" 2nd hand one
I hope you solve, but if you don't....then I think we have to sell it "as-damaged" (or return it in warranty if you have)...I'm actually looking for a Diamond or TyTn II (see hard choice... thread ) and leave this dear mate
what i was afraid of
This is what I was afraid of. No warranty here so have been thinking of moving to the Tilt, but I am leaving town in a day and have no time to get and set it up.
Its also possible if you dropped your Hermes you may have cracked or bent the battery connectors.... May need to be fixed with soldering iron but is a pain if you can't solder really tiny joints...
Cheers...

I'm ready to go, I want my Hermes back
Can you point me to some photos to understand where to solder the connectors better?
I mean, I've already seen them (so many times hehe), I also have that cool yellow gauge that could be useful to understand if they don't "touch" correctly, but I'm not sure I understood where are the soldering points
A photo with some arrow could be useful (or something similar lol).
Many thanks for your help mate!
The best idea would be to go Here - http://michael-channon.spaces.live.com/
Mikes site offers the best tutorials for the Hermes, and, if you need to you can pm him directly.

What a lovable guy! So available, so kind, cool!
Guys, just to let you all be near me...with my hearth that cries at every Hermes black screen...I've opened it again, did some tweaks - again - and did a complete photo-report and a short video too!
See here
http://s403.photobucket.com/albums/pp120/ErMejoo/My%20v1605%20opened/?albumview=slideshow and for the video choose "Main" on the top corner.
I'm looking forward to the next Mike answer (just sent him the link too) to see if he thinks detaching and soldering again the battery connectors can be the right next choice.
If someone has some ideas or if I have a great one (don't think so but the hope never fades away) or simply for kind words, let's write here.
Thanks to everyone giving support, I really appreciate.

Sorry was feeling a bit sick yesterday and didn't reply.
Having looked at the pics an video, I am begining to think one of two things:
1. There may be a crack in one of the battery connector soldered joints
Or
2. This has nothing to do with the battery connector and may have more to do with the general condition of the phone.
Number one could probably only be checked by re-soldering the contacts.
Number two is quite unspecific. You see when I look at the pics and see the gaps in the casing, and some damage to internal plastic, I get the feeling that the circuit boards etc are probably not be firmly held in place. In other words there is likely quite a bit of movement internally and between the two halves of the phone.
This in itself could cause the battery to move around. It could also cause the rigid flex cables to move at their connectors.
I think you need to check each and every connector is well inserted AND try to firm up all the looseness and movement internally and in the casing . I'm not sure that wlll be an easy job given some plastic parts appear broken.
I think it's going to be difficult to give further advice (not being able to see and feel the device directly.)
However, I'll have a look at my Hermes this weekend, and try to establish a link between pressing certain areas of the keyboard and a total shutdown.
Cheers
Mike
Thanks Mike, don't have to apologize, you're offering free help
Anyway, I have the WORST news for you....my Hermes has gone, completely.
After the mail I sent you the other day, don't know why really, perhaps for the spray, I don't know, it didn't switch on again.
When I connect the battery charger it comes red, and if I remember what I read somewhere here red means it doesn't feel the battery at all.
I tried to leave it outdoor these 2 days to see if magically that spray which left a film everywhere would have evaporated but this didn't help.
I'm having a very "rude" welder as I said, it has a cutting tip just to make you understand, anyway I've just toggled the battery conn with it (I had nothing to loose) and I have the 2 centered one which took away a dark "film", and on the motherboard I have the 2 silver connectors on each side, which touch 2-by-2, and the 2 centered one which are completely black...don't know if I damaged something that way...
I think tomorrow I could try to weld 4 wires (what are the centered one for?) and see what happens...what do you think?
I'd like to try everything to even explore the 0,01% possibilities to see it working again...
[EDIT 1]
Just updated my album on photobucket with the new photos...

Yes it means the battery is not charging - which suggests the connector is now disconnected even if it wasn't before.

Now!, I think something has happened to the translation here!! Does this welder (let's call him Fred) swear at you and call you rude names? And when you say you have had him!!!
Sorry - I have a weird sense of humour.
Anyway. To be honest, given the general condition of the phone and it's various problems - I think you should start looking for a new phone - you will never be able to rely on the one you have there.
You could also consider making a small amount of money ny selling off parts from the one you have. Folk here are always looking for difficult to find parts.
Sorry to be defeatist about the phone, but I think you realise that it's condition is getting worse not better. Assuming money is no problem then it's time to get yourself a present

In short, my sister got a new bricked one (DOA) and is waiting for a replacement for 2 months; my dad bought one on ebay and got cheated for 270€...now I damage my phone and want to buy at the shop with him and it ends two days after we had seen it there...if this was a film I'd call it "Nokia N95-8gb: the nightmare"!

Well you have nothing more to lose by continuing to try things out on the Hermes.
A couple of points regarding your pictures. You know you can upload the pictures to photobucket and then using the direct link that photbucket gives you below the picture you can then post the picture on XDA-Dev. You use the little "insert image" icon when writing a post. As shown here:

I'm not sure what that black film on the central connectors is. Perhaps it's melted plastic from the connector housing. In any case you should be able to melt it off. (Be careful though because excess heat may be transferred into the board and start loosening other connections. The Hermes has a multilayered m/board and some connections are "sandwiched" between the layers).
I see the picture of the spray - I assume it is a metal polish? It may or may not conduct electricity - if it does that could cause serious problems even after it's cleaned off.
Mike
PS
By the way a welder can be a person who welds or a machine that welds. But you said that it was a rude welder. A machine cannot be rude, so a "rude welder" as you stated, must be a person!!
NB Welding is a term used for joining large pieces of metal. When talking about circuit boards we normally say soldering not welding.
My Italian lessons (thanks to Chiara from Tomtom) are coming along nicely:
Alla fine della strada, girate a sinistra.
(But I don't care I could listen to Chiara's voice all day long)

Thanks for the lesson I needed, much appreciated
I just realized the "rude" adjective refers to a person, I used it because in Italian saying something/someone is "rude" or "rudimentale" means it/he is simple, old, rudimentary or primitive...and here we use it for both things and people...think you'd say unkind if it was a person.
Speaking of the Hermes, those 2 black ""connectors"" you see on the board in that photo have not something "more" comparing to the others, but something LESS! It's sort of scaring after having read about the layers, because under the gold connectors, after having removed them, I could detach just a sort of LAYER (that's what I meant with film), which btw didn't seem conducting side-by-side
Will update when I have some time to try the cables ""solution""!
p.s. You'd LOVE Selen's sexy sensual voice for TomTom I think...she's (was) an Italian pornostar still well known...See Wiki!!
Did you remove the traces? That's almost what the pics look like. By that I mean the gold under the solder.

I got scammed on Ebay over an Xperia Play

So guys, I got scammed on ebay this week.
I saw a listing for a Xperia play for 40 dollars and I've needed one ever since my phone got eaten by my dog.
I took a chance and spent the money on it.
The seller told me in the listing that the phone was fully functional.
Skip ahead today and I got the phone.
Right away I could tell it was going to have problems. The USB jack was totally screwed up.
I've never seen one this bad actually. Anyways I get home and sure enough the phone wont charge or anything.
I put a new battery in it, and the phone wont even boot up.
So at this point I'm getting pretty upset.
I contact the guy on Ebay and tell him, "Listen this device is broken. I want a refund. Not only is the USB jack broken., but the motherboard is also bricked". Mind you, this was after he listed it as fully functional.
So he tries to refund me 15$. I told him no way, I'm not paying that much for a busted Xperia.
I told him, I'll take a 25$ refund and leave good feedback if you do it.
So he refunds me the cash and I started taking this thing apart since I'm going to be keeping it now.
Right away I see we have a problem.
The WATER INDICATOR, is clearly been soaked and red.
So not only was the USB jack fried but also the phones been dropped in water and the motherboard is bricked.
The only part I could salvage out of the phone was the LCD screen and digitizer.
It would be ok, except my motherboard has a bad USB jack too. and I cant repair it because I don't have surface mount solder repair station at my house.
If I ask a company to surface mount a new USB port onto the phone, they will ask for 50$ or more, and I can't afford it.
So if any of you nice people have a broken phone with a good motherboard, let me know. I can pay up to 25$ for the motherboard.
Until then I might not be able to do any developing. I don't have USB access and that's a major problem.
Thanks for reading and let me know.
Just to let everyone know I'm serious about repairing this thing.
Here is a recent picture of all the parts I have around my house.
I actually have some more but their not in these pictures.

You definitely shouldn't have had to put up with that. If the listing was covered under eBay Buyer Protection, you should contact eBay. The dude clearly listed the phone incorrectly. What a jerk.

Yeah you're saying it nice.
He actually lied big time because the listing said it was fully functional.
Not only was it water damaged but the board is bricked.
I hooked the test points up to my computer and the motherboard is throwing up a brick code. one that I know isn't repairable by anyone on this board. (the BIOS is corrupted and now it's 100% locked)
He knew for a fact that this phone was garbage,. I don't know why he lied tho.
The guy has really decent feedbacks.
Like 500 sales and 99.8% score.
Anyways we settled outside of ebay with the refund thing.
I didn't want to totally pay nothing, since the screen was salvaged off the unit.
But yeah., It was a really scummy thing to do.
I have some better news to report.
I have a semi-decent motherboard now.
The USB pins are messed up but atleast its making a connection.
Alejandrissimo @XDA used his SETOOL program remotely and helped me recover the board that was stuck in zeus mode.
Long story short. I'll be able to update the rom after all.
I still need to get ahold of a better Mobo tho, so If anyone is selling a spare, let me know.
I can send you some parts just for the cost of shipping, but I don't know if you can do anything with it.
The motherboard work, but it can't detect sim card anymore. It still have an IMEI number. It has a strange behavior that if the battery is not drained yet and the phone is on, it can charge that battery. But if you leave the battery in the phone, whether the phone is on or off, overnight the battery will be drained completely. Then it is impossible to charge the battery even if you connect it to the charger, unless you put the battery into a different Play, or possibly buy an external charger. It can still connect to the PC for flashing and fastboot, etc. I also notice it have problem booting into stock firmware unless it is powered on by the charger. However, it boot fine into custom roms from battery power.
Other things that doesn't work: Digitizer, Start and Home button (both of these can be easily remapped in the keylayout file). The problem is to flash roms most CWM version require the Home button. There is one CWM version that use the Search button however. Also the main cable is kind of worn, but still working. R button a bit unresponsive, unless you don't screw it in at all then it clicks perfectly.
The only usable thing I can do it it right now is to charge the battery externally and use the gamepad to navigate and play games without touchscreen. I do not think the sim slot is damaged, it might need some kind of reprogram. Other things I confirm working: screen, camera, speakers.

No, the last version Verizon update the R800x to officially is 2.3.4. Otherwise you will have to install other custom roms.
I run the R800x with stock 2.3.4 rooted, I just use LBE Security Manager to freeze apps and disable them autostarting.

Hey, I was wondering where the seller was located? I recently sold an Xperia Play and when I sold it the buyer said that his son previously had one and jumped into a pool with it which is why he was buying mine... I'm very curious if this is the same person. The time of him buying a new one and you buying yours seem to match as well.

How to get Samsung to fix the Blue Screen issue for your ATT SM-P907a

After sending my tablet (SM-P907AZKAATT) into Samsung repair 3 times they have finally fixed the issue of the Blue Screen of Death (BSOD). The issue is caused by the motherboard as most of us know or suspect. They don't call it a motherboard though. They call it a PBA which means Printed Board Assembly. Typically the PBA would literally mean a blank circut board but in this case they are referring the the entire board; I seriously doubt they are moving all the components to a new board, LOL. As I said, this was the third time I sent the tablet to Samsung to be repaired but this time I uploaded a picture for them to reference and I told them not to send it back until they have replicated the screen. I also told them exactly what the issue was as I had the first two times; I understand that they can't take my word for it and just repair what I want repaired but it gives them a suspect, at least in their mind.
I have attached the picture I used. If you can't snap a pic before the blue screen is gone on your tablet just use mine.
I think that's about it but I will answer any questions you may have.

Just an update. No blue screen since being repaired. This is the fix...
People are still looking for a fix... Consider making this sticky.
I support this. I used this method. I've not had a blue screen yet.
How do you get in contact with someone to make this sticky? I have PM'ed several moderators and no one has gotten back with me. I've been trying for weeks. The only reason I've been so persistent is that people are still looking around for a fix for this and this is the solution. I would appreciate if some could point me in the right direction. Thank you.
It has been 4 months since this repair. Still no BSOD. Once again I'm asking the administration to make this sticky because there are many people still looking for a solution. Can someone help me with this?

That makes no sense. If they can see your tablet get the bsod that means it's still faulty. I must be missing something lol!

I'm adding my name as a successfully fixed case; bought a used AT&T Galaxy Note Pro 12.2 off of Amazon, and it was having the bluescreen issues. Unfortunately I noticed this after I had already rooted the device so I could take the resolution out of kindergarten mode; but, I took a picture of the bluescreen and wrote a quick note that I included with the device when I shipped it in for warranty service indicating that I'd read online a faulty PBA was the cause; received it back in a couple of weeks, and not a problem since. Re-rooted and good to go, thanks for the tip!

That's awesome to hear. You're welcome.
The Solution & The Problem of the Note Pro Bluescreen
----------------------------------------------------------------
THE TRUE ISSUE - THE TRUE ISSUE - THE TRUE ISSUE -
----------------------------------------------------------------
This is a language barrier / communications issue with the support staff. I did a live chat and I should have included a picture of the blue screen but instead I meticulously explained what the problem is and that probably failed still because when i checked the repair status they showed LCD display issues. So i called them up while they still had the tablet in their possession and before they looked at it and specified over the phone to correct the description of the problem they have annotated in their database. I explained all the same stuff about the issue and how it is a known defect in the AT&T variant of the 12.2" Galaxy Tab and that it has even garnered it's own name (borrowed from Windows): BSOD or Blue Screen Of Death online. When I sent it in they had the wrong issue labelled in their database: bad LCD/ Display issue.
----------------------------------------------------------------
- THE FIX - THE FIX - THE FIX - THE FIX - THE FIX -
----------------------------------------------------------------
Contact support and get your device replaced. It is a defect in the hardware and will be fixed free of charge. Include a picture of the BSOD so that they know what the issue is that they are fixing. I used live chat for the initial contact. Phone support is probably better. Also you could try hanging up or starting another live chat if you see you are dealing with an idiot or someone who has just recently learned English.
Note: They erased & updated my tablet to lollipop 5.1.1 probably in their troubleshooting process. I haven't been able to re-root my device since they updated it to 5.1.1.

(THE TRUE TECHNICAL ISSUE)
----------------------------------------------------------------
I will try to update this in a bit. For now here is what I know:
I got mine fixed right after I bought the Samsung Tab 12.2" SM-P907A off of eBay with an unadvertised BSOD issue . The issue is caused by something wrong with the PCB (Printed Circuit Board) or motherboard or as OP described the vernacular they use: PBA (Printed Board Assembly). Whatever you want to call it there is something wrong with the mainboard on the AT&T version of the 12.2" Tab S (SM-P907A). Someone (I want to say from Samsung but I cant remember for sure who it was) told me it was related to the battery, I believe it isn't wired to the motherboard well enough and when the system demands too much power and the battery cannon provide it properly through those leads then that is when it BSODs. This would make sense since it happens usually when you are heavily taxing the system, i.e.: playing a game. I installed some heavy 3D graphics games on mine when i first got it to see if I could insight a BSOD and sure enough it happened in no time. I noticed it normally wouldn't do it while sitting in stand by, but often would be insight into blue screening as soon as I started using it. I have shot some decent videos of both ways the BSOD manifests itself. I will edit this post when I locate the videos I took and take a moment to upload them. When I received my Tab back they noted that it was power related and included a new usb cable along with a letter saying to not use the old cord as the problem was power related and they fear that using the original cable may damage the tablet again. They only sent the cable, not the AC adapter and ironically my AC adapter although I never felt it get extremely hot (remember I got this slightly used off of eBay so it may happened before I had it) but the electrical prongs that plug into the wall are actually out of position and under closer inspection you will see they have moved because the plastic actually melted a bit where the prongs come out of the AC adapter. So now I am chatting with live chat again just to get a new adapter. ^ ^ ^ SEE THE TRUE ISSUE AT THE TOP OF THIS POST ^ ^ ^ Have fun with your chats with these ESOL ****tards they have manning the support desks. I will post a couple of mine as I cracked some good jokes...

See my last post in this thread it tries to clarify. The help desk staff suck at english and do not relay the problem properly to the technicians who actually fix it and they don't sit there playing with your tablet until an error manifests itself. See my post please.
Well I got screwed. Sent mine in for service, it was supposedly fixed. A few months later I get blue screen and flickers that lead to a restart. Now it's not under warranty and Samsung won't do squat. Biggest waste of money. This version has so many issues you can't even trade it in for value anywhere. All the carrier trade ins have it valued under $50. Best Buy doesn't even list it. Had a perfectly working wifi version and sold it for this and have had nothing but issues. And to add insult to injury, Samsung sent it back to me locked when I bought it unlocked. Never even had a chance to use it on tmobile.

When i upgrade my P907a to lollipop, it never has BSD
Just an update... Not a single BSOD in almost a year.
Still want to make this sticky but I've long lost hope on that.

I bought a new motherboard, how to prevent the dreaded "EMMC Bug"?

I ordered online a motherboard for my dead N910G due to EMMC bug and I'm thinking on what I'm gonna do to prevent It from happening again on the new motherboard. I didn't yet receive the new motherboard and I'm assuming that it is currently on Android 5.0.
Do I need to stay in Lollipop and don't bother to upgrade it to Marshmallow? Or maybe, put a custom rom instead? Or how about putting another layer of material between the emmc and the thermal pad(though, I'm thinking to replace the thermal pad with something thicker instead, maybe 2.0mm)~I'm quite aware that this one is "fix" for Note 4s already experiencing emmc bug. Or is it something that's inevitable and probably die again within months or years?
Any suggestion is greatly appreciated.
Thanks!

i'm thinking of doing this too but this is more of a "fix" for note 4's that's already experiencing emmc errors instead of a prevention. But putting a fresh thermal pad can't really do harm so I might try to do this.

My understanding of the eMMC chip failure is following: it is due to the crack in the soldering. Have a vague memory of reading that Samsung even got sued for using bad materials. Anyway - Some temporarily fix the issue with cardbord (linked above), which then i believe works simply by pressing the components together and thus in best case re-establishing the electric contact within the circuit. Tried that myself, didn't work for me. Certain apps will perhaps help just a period of time by tweaking some settings, which i believe relieves the pressure off of the chip. To hold the phone in the freezer every now and then to get it to start is just not feasable. Did that too, works for a while, again, probably due to the material shrinking a bit in the cold thus making components connect again. What remains for me to try is actually having it in the oven for couple of minutes (yes, people have tried that too... ). I have a couple of old spare ones so it's not bigger shame if they break completelly.
But these are all my experiences with workarounds/temporary fixes when issue ALREADY is there.
I did replace a few motherboards. Those i orderered came with Marshmallow, which i was happy with. Don't know where you ordered yours from, I got mine from China but no issues anyway. If you got it from China, check the IMEI number tho. Specially the motherboards on older phones can suffer from bad IMEIs. Also use some app that can see in the system if it is the right chip you have, otherwise trying to flash custom roms might not end well…
My experience has so far been good. After replacement i played with both stock and custom roms and so far nothing broke again after more than half a year. As for your question of prevention - so far i haven't found anything that would lead me to believe that it might prevent it from happening again. So i got me a spare Note4. And a couple of spare motherboards in case they break. I don't really want to open those i use as daily drivers, since they never really feel as tight afterwards. And as far as i understand, there is no way to predict if your motherboard is going to break. So it's a gamble.
Edit:
And a friendly piece of advice regarding the replacement itself: take your time and preferably couple of valiums. I armed myself with lots of videos on youtube on how to do it so I started thinking i was a pro, which i clearly wasnt so i didn't take the time. So i took me a couple of broken screens before i mastered the art of … not breaking the screen. Not every time at least…
Use heat gun. Right tools. And did i mention to take your time?
Btw - the two connectors (you'll see which ones i mean in due time) are a pain to connect. THERE you can use some padding to sort of lift the connectors that are on the phone so that the connectors on the motherboard can click in them more easily.
Good luck!

HI - did you replaced a MB from a Snapdragon variant with another MB from Exynos variant, please?
Like I have my son's 910F and I'd like to buy a replacement MB of 910C.
Any experience on this? I understood from other users that there are some issues with cameras. Probably no show stopper for me, but just to confirm if that's the case and if after replacing cameras all was ok.

I expect to receive the new motherboard within this week and I already disassembled it in advance. I managed to almost separated the lcd screen to the motherboard tray because I didn't watch closely enough the tutorial that I'm following to and I wedged the prying tool parallel to the screen. Fortunately, nothing cracked and it seems the screen held up fine, (well.. hopefully.. still crossing my fingers 'til the motherboard arrives. lol)
By the way, I have a few questions regarding on reassembling it back. First, can I replace the thermal pads with thicker one? 1 or 2mm thick is what I can buy here locally. And second, can I use something like B7000 glue to reattach the screen to the frame? I'm gonna put it along the red line shown on the image below.

Regarding thermal pads i am reasoning this way: given the supposed cause of the issue, installing thermal pads would perhaps only delay the outbreak of the issue for a while, should it occure. Putting too much thermal pads would on the other hand perhaps put too much physical strain strain on the circuits, well, depending on how soft or hard they are. So if you're planning on scraping the old thermal pads, i'd go with 2mm ones, otherwise 1mm.
Please remember tho that i am not an expert even tho i did read up considerably about the issue. So i cannot guarantee one approach or the other is the right one.
As for the glue, i never used it. Used one of these instead:
https://www.aliexpress.com/item/328...earchweb0_0,searchweb201602_,searchweb201603_
Reason i never used the glue is that it's not unusual that after you assemble stuff, it turns out something is not working right so you have to disassemble. Then you make everything work, assemble it again, and then something won't work anyway. Especially so when you are still learning. So i never dared using glue because having to open it again after having used glue would make one glorious mess. I was learning and, well, playing. Besides, like i said, i never had to disassemble any of my daily drivers so it didn't matter that they perhaps don't seem to sit 100% tight.

Just for update, the motherboard finally arrived today and mounted it temporarily yet just to test it. I'm still waiting for the adhesive and the thermal pad before I can seal everything shut. I tried to connect it to charger and the vibrator motor "bleeps" for few millisecond but the screen didn't turned on. Does this just mean that I didn't connected the connectors at the back properly? I only tried it once and I didn't put a padding like what you've said on the connectors yet.

You mean the battery indicator doesn't come on on the screen when you connect the device to charger? Can't really say, i think it should come on, yes. To check that - when charging, try and press the start button shortly, that usually wakes it up and it will show the battery indicator on the screen if you connected the MB properly. But why don't you try and start it up if you got the new MB connected? Then you can see if it works and if it's connected properly.
Usually if you get the connectors right, you will hear a 'click' when they connect.

Another update, I took my time connecting the new MB but still, the screen won't turn on just like the first time I connected it just to test. The LED lights up red indicating that it's charging and I connected it to my PC and it shows up on the device manager. When I press the power button, it vibrates indicating that it is indeed turning on. Also tried entering to recovery and download mode with no avail.
it's really just the screen is refusing to connect or something. I already shoved a piece of cardboard to the connectors and I hear a satisfying click when pushing the MB in place. Should I just keep trying on reconnecting the mb?
P.S: I'm starting to think that I might just killed the screen accidentally.

Check thoroughly up close the integrity of the LCD directly under the glass. If it's broken, then there will sometimes be very tiny cracks in it.
But of course try and re-connect everything again. Don't forget the Little black screw on the left hand side of the MB when you're reconnecting it. Sometimes it won't work without that screw in place. Try also and remove the extra thermal pads you said you would install.
PS. There are LCDs for N4 on aliexpress that nowadays don't go for much. Tried several sorts and they usually work good.
If it's any consolation, the N4 is apparently one of the trickiest devices to work with…
I can confirm that, to some degree, snapdragon and exynos motherboards are compatible.
I had a N910A with a defective mobo and a N910U with a cracked screen. So I placed the N910U mobo in the N910A body. I used 910U modems and everything works fine, with the exception of s pen silo detection, which could be a result of this.

I managed to kill my 9 yr old Alienware while performing a GPU upgrade.

I am the original owner of a 2013 Alienware 17 R1 I bought myself as a treat a long time ago. I opted for the 770M to save money, and it's served me well over the years. It's survived my military career, a nasty divorce, a car crash, and moving halfway across the country. It's never once let me down.
I decided to upgrade the GPU to try to lend it a couple more years. Since I wanted a plug and play solution, I ordered an 880M from Amazon; that arrived yesterday. I already had the 3 pipe heat sink ready, with some adhesive thermal pads and thermal compound.
So, after applying thermal pads to both the heat sink as well as the GPU, I went forward with the install. It's pretty straightforward in this laptop - remove the bottom cover (2 screws), remove the GPU fan (3 screws), remove the GPU heat sink (4 screws) and finally remove the GPU (2 screws).
It had been running beautifully before the upgrade. As they say, "if it ain't broke, don't fix it..."
I installed the new GPU and the new heat sink, then put it back together and pressed the power button. Nothing - no lights, no beeps, absolutely no response at all.
So, I removed the GPU and put the old one back in. Same result.
I removed the GPU entirely. No dice.
Feeling desperate, I removed the drives and the palmrest, and inspected/reseated the ribbon cables connecting the power button/light board to the card reader board, and the card reader board to the mainboard. I also checked the power connector too, even though it's on the opposite side of the laptop from the GPU side. Nothing worked. I tried a power drain - unplug battery, leave AC adapter unplugged, hold down power for 30 seconds. No good.

At this point, I suspect that this "tested and functional" 880M from China is shorted out and damaged my mainboard when I applied power. I have a replacement main board on the way; if any of you are familiar with these laptops, I'm all open to ideas.
This is my main PC. I really don't want it to die. Sure, my wife has her HP all in one and Asus laptop, but they're both slow as snot, barely sufficient for web browsing.
If I'm unable to resurrect this thing, I'll probably be building a PC. To that end, here's the parts list for suggestions/critiques.
Ouch. Sorry to hear that.
There may be a fuse* somewhere on the mobo around the power section. Try pulling power and see if it resets will original hardware. A schematic or any internal diagrams be helpful for you.
Bear in mind that you should follow ESD safe practices when handling the mobo and chipsets out of circuit. It takes very little static electricity to damage them. At least raise room humidity to 50%, wear all cotton and work on a bare wood surface. A earth grounded ESD mat and wrist strap are best.
*or a fusable link, resistor, etc. Maybe a surface mount.

Not terribly likely in a laptop but I'll check anyway.
I've been in the electronics industry for 16 years, but you can never be too careful.
I forgot I had the same problem a couple years ago after messing with BIOS settings. I didn't in this case, but I'm going to try resetting the CMOS like I did then. If that doesn't work, new motherboard arrives tomorrow. And on the plus side, I found someone selling his 980m for $150 2 states away, $100 less than I'd be paying for something of questionable origins from China.

Yeah. Well, again, I didn't change anything before I shut it down for the upgrade. I checked to make sure it was in UEFI a few days ago but I didn't change anything, and rebooted several times between then and now. I don't know how swapping the GPU would mess up the BIOS, and to make matters worse, there's no clear way to reset the CMOS; removing the hold up battery requires removing the main board. Stupid Dell. Going to tear into it today, and if that doesn't work, new main board gets delivered tomorrow.

Yes well... read this.
You may need to flash a different bios version.
This site may be more useful to you, maybe someone that has done this before will reply.
Copy your current bios settings down.
Make sure the new mobo bios version is correct... it's always easy until you do it

I'm talking to some guys in the Alien Resurrection discord, the only thing I should have to do is modify the driver INF, and even then, NVidia started shipping universal driver packages in 2014, so it may be plug and play.
Regardless, none of this should have killed my computer. At the very most, I should have got a POST code, but even then, it's most likely that it would have booted into Windows and been unable to recognize the GPU. It has both integrated graphics and discrete (NVidia Optimus).
I tore into it yesterday, took the mainboard out, and removed the CMOS battery. Carefully inspected the board and cables, nothing seemed amiss. Followed a recommended guide from the Discord guys on a NVRAM reset, didn't work.
New mainboard should get delivered today. GPU seller has apparently accepted the return but has not yet sent me a shipping label, and there is no way in hell I'm paying to ship this back to China.

It's hard to say especially when it's stone cold dead. A fuse of some type mounted on the pcb or elsewhere. A tech that's work a lot with this series be more knowledgeable.
It could be a solder fracture that resulted over time and flexing the pcb just a bit opened it up.
BGA's are real suspectable to board flexing.
If made with no lead solder it was born to die... no lead solder is awful.

Well, I got the new mainboard, swapped the CPU and RAM over. Booted right up. Reassembled laptop, everything is running beautifully. The only issue now is that all the AlienFX colors are pink so I have to download the software that controls that....
Seller of the bad GPU still hasn't sent me a return label, and I wonder how much success I'd have going after them for the cost of the mainboard
