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...

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

Well I will, as soon as I can...currently I can't, that's why yesterday my father wanted to help buying 50% (200€) of a Nokia N95 8gb to let me use it and wait better prices for the HTCs out there...and take the Nokia for himself when I decide (what a profiteer haha!!)...BUT of course the shop finished them ([OT]there's a long story for N95s here, everyone wants it but noone gets! 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"!

Thanks for your help anyway, much appreciated!

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)

I didn't try to add all them here because, you know, photobucket slideshow is so sexy
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 have had the same issue at time too..if you still think about your warranty then go to local service center..and clean the phone..
or...
you can try the tips below:
http://www.berryreview.com/2008/12/22/faq-how-do-you-clean-your-trackball/
Wal-Mart sells these individually wrapped, pre-moistened lens cleaner cloths (kind of like the hand cleaner packages you get at some restaurants).
Anyway, they’re called Zeiss Lens Cloths and they sell them in the Optical Section, up front where they sell eye glasses. They clean the BB from top to bottom extremely well and help brighten and clean the trackball. Package of 50 is like 2 bucks.
I find with the q-tip method the cotton sticks to the trackball. my 2c
xavier – thanks for your post, i tried your suggestion for the Zeiss Lens Cloth premoistened wipes and it worked perfectly and I did not have to open the Blackberry Bold to solve the problem. I keep these wipes around for numerous uses in dealing with eye glasses, lens, or other similar uses. Thanks again.

If you have the warranty, might as well just take it in, but I have the cloths all ready, so I just clean it.
The pre-moistend lens cloths are used with the device intact. I just wipe down the trackball real well, rotate it a bit and continue cleaning until it rolls freely.

It happened also to me couple of times. Just blow quickly at the trackball using your lips or presurized air for computer keyboards. Not sure about any wet "ass wipes" which may leak into the phone inside. My method always works (so far) Service repair is last instance. Good luck!

The wipes don't help, the track ball opperates on a magnetic principle (the pick ups are soldered on the main board, the movment is controled by magnetic cylinders.) I had to send my phone in to htc after about two months, they replaced the main board and trackball assy. I had it appart also, there was nothing to clean, nor to fix. All sold state. (except the little rollers)

Ok so I was having the exact same problem, and I used to do tech support for these devices so I kno that they work just like a PC mouse. So..... wat I did is I took a straw cut it long way down (hotdog style if you remember how to do that from 1st grade haha) it into a very small size, about just enough to wrap around the trackball half way. Then I inserted the straw into the slot between the chrome and the trackball (this part can take some time so just be patient) you will be surprised how deep it can go, I went all the way till it stopped. Now you will have the straw sticking out of the BOLD. Bend the rest of the straw down so it is now folded parallel to the bold but still sticking in it. Now wat I did is I spent it clock wise for about a minute then yanked it out and you will notice a ton of lint/dirt pop out, after this you will want to blow on it while rolling with your finger in all directions. You should be seeing a lot of dirt rolling around by now, and also the straw will have a tiny bit of wear on it. Proceed to do this as much as you like but doing so in 1 direction will produce more dirt. I went clockwise about 5 times then counter clockwise about another 5. Then viola it was like brand new. Hope this works for you crackberry heads out there. Deuces!!

I Just disassembly my HTC Snap s522 to clean the trackball today,
I can confirm you now guys..the htc snap s522 trackball is same type like blackberry 8310 trackball..so you can replace your trackball with BB 8310 trackball.
I just tried my friend Blackberry 8310 trackball and tried to running it on my snap..and it worked well.

you guys are looking too deep into this lol. this happened to me just push the ball in and move it around it will start working again

our snap use same type like blackberry trackball and sometimes the trackball will stop working till 6 months of use..(base on report at BB forum) the ball will become slick after 6 month.
you will need to know how to replace the ball (after 1 year service guarantee expired) anyway..thats why i concern about the trackball..
For me Being to know i can use the bb trackball on my snap is great..because cheap aftermarket BB trackball is everywhere in my country only $4 (include trackball house) compare to costly oem ball (will cost you about $20)
My tips:
You just need to keep the OEM trackball house and use the cheap aftermarket ball on it, you willl still has HTC OEM trackball performance on your snap.

FIXED: G2 Hinge Teardown/Repair

So, I decided to fix my G2 hinge which was a little on the loose side but didn't want to use magnets because it would affect the Compass. If you don't think magnets do affect the compass, i invite you to open up HTC or Google Navigation GPS app and wave a magnet around your phone and watch your direction change.
In any case, I looked for a teardown online in hopes that it would show the actual spring mechanism for the Z-Hinge...but all of them seemed to have skip that part. So...here's a photo of the ACTUAL MECHANISM responsible for the "snapping/springy" action of the phone. As you can imagine, assuming you can get to this point in terms of disassembly, tightening up the mechanism is SUPER EASY. All you have to do is take out the spring, stretch it, put it back in. I think the only way they could have made this mechanism smaller and more reliable is to have used a tiny hydraulic piston in place of the spring, but since I'm an EE and not a Mech Eng. well, what do I know!
<EDIT>
Link with instructions for taking apart your phone. You will need a T5 Screwdriver and a puny Phillips Screwdriver.

P.S. I can have the KB open, G2 upside down and shake it fairly vigorously before it will begin to close now! Definite improvement!

Damn...
Assuming you could find a spring small enough to fit you could buy a spring with a higher tension. That's what I did with my Ruger LCP to help the feeding cycle.
You could have taken a couple dissemblely pics to help us get to that point.
Thanks for the info.

Might want to add this voids warranty. Lol. Secondly if you could add some insight as to how you actually managed to disasemble the phone to access the hinge. That would be great. Might actually try this myself. Big might. Lol.

Tear down is here...
http://tjworld.net/blog/htc-desire-z-tear-down
You only need to tear it down as far as PCB Removal to access the spring mechanism in the hinge (its the top side near the power button). BE SUPER DUPER careful with PLUGGING IN the micro-SD ribbon cable when you reassemble. One of the spring tension pins (its a flip up type ribbon cable clamp), broke off on me. I was like OMFG for about 2 minutes until I realized it was just the tension pin NOT an actual connection pin.
Oh yeah, and for anyone that hasn't figured this out already...WARRANTY = VOID!!! Oh, and the normal CYA (cover your a$$ clauses) apply...I'm not responsible for any damage etc. etc. etc. that YOU might cause doing this fix/mod.

Thanks for finding a REAL cure! Magnets lol! morons... nice work though! I glad you found a fix for those how have (or imagine they have) a hinge problem. maybe this will shut folks up about this finally...

Nice job man. Quite the set of balls you got there my friend. I may try this when my warranty expires.(and my hinge gets to a point where i can,t stand it.)

Now I havn't tried magnets on this phone (or any other).. but I do know that the magnetic strength of magnetic tape, such as was used in the other "fix" is not very strong at all, as it barely strong enough to work as the fix it was intended to do, for this reason I could believe that it had no effect on the compass.
However sure, if you use a proper magnet it will mess things up.
However, very nice job on this but I doubt many will want to void their warranty when they could just send it back under warranty and do it that way.

You are correct about the warranty. Although there are a few stickers on the torx screws that say void... they won't refuse your phone and claim that your warranty is voided. Its bs. They just check for eextremely obvious things like water damage and physical damage. I was a cell tech forever... they hardly care about that crap like is its rooted or whatever. Just don't make it too obvious like a phone stuck in a boot loop with cyanogen logo flashing over and over, lol!
But it does depend on the tech... if he/she is an asshole and dont root their own phones or hack... they could reject it. personally, I think those are the type that have no buisness being a tech nor would understand that rooting a phone is going to cause any serious damage to it. unless you flash the wrong spl/hardboot but at that point... 90% likely it wont even boot into bootloader in which there's no way to tell what happened whether it was a custom flash or a bad board. those are instant replacements as long as there's no physical/liquid damage. well, sorry for hijacking the thread and my poor spelling. good work with the hinge, OP! those ribbons can be a pain to reseat!

I'm doing this tonight @ work. Thanks for being the guinea pig.

dude great find....but way toooooooooo deep for me....If my hinge continues to drive me insane, I'll just start calling tmo like crazy until they give me a anew phone.

Stretching the spring is a good temporary fix. The best real fix would be to find one the same size but with a higher spring tension. Good find none the less.

So I HEARD something interesting today. TRY THIS....
1st: Turn Off Unlock sounds if you can.........
2nd. Put the G2 close to you face, open the screen (top) very SLOWLY.... when the screen is parallel to the keyboard (halfway) push it a little bit more and you will HEAR a CLICK..... im guessing its the spring... but my understanding is that if spring stays stationary (in one spot) and just twists..... there shouldn't be a click sound..... which means something is mis-aligned (maybe the hinge part that is connected to the spring)... my hinge came in good condition, still stays intact when I hold the phone upside down.
Those of you with loose hinge... I encourage you to try this....

Um .... click? misaligned? i think that if it twists, then it should be in good shape as it's doing what it ought to be doing.
Either way, my hinge sucks, and there is no click....

I was just thinking about what the teardown again. Now that I really consider it, I don't think that I had to unplug all the cables, just unscrew the PCB. I think there is enough slack to carefully maneuver the hinge out..maybe. LOL. Where do you get replacement springs? I guess I should really have measured the length...maybe I still can from my photo and a couple reference points.

Ignore the click...its not a "misalignment" of the spring or stars or whatever else. Look at the photo I posted, it doesn't matter if the spring twists. In fact, I'm pretty sure it does swivel and move in there. The back end of the spring is simply braced against the metal side. The other end against the actual "pivot" (2 pieces of very smartly cut plastic) is "centered" in place with a small pin jut like most other hinge/spring mechanisms.
Now if someone could tell me where to get a super strong spring...I'll be all over that! LOL. It was already really hard to get the spring back in after I stretched it but a mega strong one would be worth the hassle...

Quick disassembly and potential touch unresponsive fix thread.

My Xoom has been rather unfortunate since I got it. I take it with me everywhere and that includes when I go out drinking with friends... It's taken many a fall. This has shown me what I deem a rather major flaw in the Xoom's design, internally. Allow me to demonstrate:

What you'll need to start... Pardon the crapola pics, I took more than this but the SD card on my Droid is going caput so most of them are just empty jpgs... Luckily the ones I salvaged were able to show the general idea. Anyways. The bit you'll use to take the back shell off is a T-5. The one I have is a T-5H but you don't need one of those, these screws don't have a pin in the middle. That's just for the first 2 screws and the screws that hold the plastic half on, you'll need a T-6 for every other screw in the Xoom. You'll also want some kind of sturdy plastic shims, I used clippings from an old debit card. The tool kit I have pictured can be bought at an auto parts store(I think I picked it up at O'reilly's).
Unscrew the 2 screws that hold the USB/HDMI/charging plate on, this will come off. Keep your screws in a secure location so you don't lose them!
That's what it looks like without the cover.
From here, slide the back cover down, you'll notice it stops at a certain point, just enough to expose the expansion card Moto will replace for the 4G upgrade. They've made this thing super easy to upgrade in the future. Slide the cover back towards closed just a tiny bit so the clips aren't resting on the stop.
Slide those 2 pieces of plastic into the grooves, as illustrated, until you can't push them in any further, you've disengaged the stops, now, with the plastic still there, slide the cover the rest of the way off.
Here's where my SD card crapped out but it's no big deal. Moving...
The touchscreen controller is located in the lower right hand corner of the Xoom if you're looking at it from the back. As you can see, mine is dislodged and there's nothing actually securing it inside the Xoom besides double stick tape. The Xoom has like 57 screws inside it and they couldn't screw the touchscreen controller down with even one? No, it's got an adhesive on the back and then it's just pressed onto the metal frame... Not secure in the slightest, even a slight drop can dislodge it. I've already tried to use a better double stick tape, but that came undone, hence I'm doing this write-up.
This is my new solution, using a thin piece of foam doubled over itself. It's about a 2" by 2" square, maybe 1/8" thick or so, couldn't tell you where I got it, I just had it laying around. From here, with it sitting there, it's kind of tricky to get the Xoom back together, what I did was start lining up the back cover with the foam squished down against the touchscreen controller, then slid the cover back to its fully closed position. My foam happened to stay in place during all of this. It may not be that easy for others, YMMV.
So I boot up my Xoom, test it out, touch works again.
I'm still not certain I'm going to stay with this solution but we'll see. For now it's working perfectly. Even exchanging your Xoom for a new one isn't going to resolve this until Motorola actually resolves it themselves, which I doubt they will. Hope this was helpful, I'm not interested in getting into the gory details of full disassembly, that's beyond my pay grade.
I also just realized this solved the problem I was having with the right half of my screen thinking any kind of touch was a multitouch and pinch-zooming constantly. Win.

Fixed images, messed up the numbering when I posted.

Good, good stuff. Thanks for the write-up - these are the threads that used to differentiate xda from the hoards of other android forums.

I he was just being funny. I laughed.

So I got the cover off, got some foam in there
but I can't get the cover all the way on... its hairline just about to close up but Im afraid to use pressure
too much foam?
quick edit:
It was a slot on the bottom i kept hitting, i got it back on!
Will update with results tomorrow
edit2: most definitely still having the same problem after adding some foam to press down on that touch panel controller. Took me like 10 tries just to unlock the damn thing
WTF MOTOROLA !...anyone have any other suggestions? this is really pissing me off now.
edit3; so I took a deep breath and decided to investigate more... I have it open again, and holding down the actual connector seems to be improving the situation GREATLY. Im going to shift the foam from the controller to the connector and close it back up, and try again

Great thread. An idea of paint the back cover (white spray) are growing in my mind.

Hello,
I just wanted to share my solution for the unresponsive screen issue with the Motorola Xoom device:
reddit.com/r/xoom/comments/sytk0
I hope this helps anyone having a similar issue. Thank you.

Man i must say ur a brave heart...i cant even think of letting mine fall...seems kinda fragile....plus all the drop test videos screw around with your head

thanks for this tip, i know how to dissasemble my xoom now! lol

Nice post. I'm having exactly the same problem and it's very easy to see reports for this same issue all around. Crappy Moto! This is the first "how to" post on this issue. Thanks a lot. I'll give it a try. put
EDIT: Following your "how to", I did exactly the same you did. The touch controller was a bit loose so I tight it with a small piece of foam. The hard part was putting the case back in place with the foam inside, but with a bit of patience I could eventually close the whole thing and now it's working again. Will see until when. Probably this device is one within many that fits in the planned obsolescence industry standard. FKU Mr. Bernard London.
EDIT 2: I actually have a big compulsion on acquiring new geeky stuff, but I hate to spend money because this is the industry standard. I hate to buy crap, and if I want to, I'll buy chinese stuff from Deal Extreme. Paying hundreds of dollars in goods from a well established and named company should be a warrant, at least, that it was built to last!
EDIT 3: I'l be moving soon to a Sammy Note 10.1. Hopefully not based on the planned obsolescence of the Xoom, but because I want it to!
EDIT 4: My XOOM "caput" for good. As I said before, I'm on Sammy note 10.1 and the XOOM will eventually go to repair.

Got my Xoom back, and it's great. Even after rooting, re flashing, opening, messing around, it was fixed for free, under warranty. It seems Motorola knows they have a case of premature obsolescence in this case.

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!

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.

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:

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.
