Introduction:
=======
Hey everyone, I'm just posting this tirade about my problems with the X1's build quality here in case anyone else is suffering from the same problems I had, as well as some tips regarding disassembling and re-assembling the phone if you're brave/foolhardy enough to attempt repairs yourself, like me.
With contributions from others this thread could become a compendium of common hardware problems with the X1 and how to identify or fix them, as well as pitfalls to watch out for when repairing the device by hand.
I don't have any diagrams yet because I simply couldn't stomach opening up the shoddy device again to take photos.
=======
My X1:
=======
I bought my X1 on eBay second-hand (my first major mistake) so I was always a bit worried what would happen when the day inevitably came when I'd have hardware problems with the phone.
However, I bought it very shortly after the phone's release and the seller described it as unused. The phone appeared mostly unused when I received it, apart from a couple of tiny scratches on the casing.
The phone was functionally fine when I received it and showed no problems whatsoever for the first few months.
Like seemingly everyone my first hardware problems with the phone (I won't even get into the device's software failings) that developed over time were an unresponsive keyboard, cracks in the case and a non-functioning vibration motor.
The 'r' key on my X1 took considerably greater force to register a press than any other key on the device, while other keys intermittently ignored presses or interpreted a single press as 2-5 presses while typing.
The spacebar also intermittently became unresponsive, as did the 'up' key on the front-mounted optical joystick.
The vibration motor worked at first, but eventually gave only a single loud 'click' when the phone should vibrate.
The problems worsened over time and despite taking good care of the phone, the casing started to look badly banged-up - This is not a phone that ages gracefully.
=======
Replacement Parts
=======
In early December I ordered a replacement casing & keyboard from a supplier in Hong Kong on eBay (mistake #2), happyhouse.cn .
The parts were suspiciously cheap compared to the ones from non-ebay suppliers, so I assumed they would be imitation/unofficial parts, not from SE.
At first glance, the new casing and keyboard seemed like the real deal, but when I attempted to re-assemble the phone with the new parts I found that the phone's original screws didn't properly fit the sockets of the new casing and that the new keyboard didn't fit either the new casing OR the old one.
I ended up using a mixture of new and old parts to rebuild the phone.
=======
My Repairs
=======
Over the course of 'fixing' the phone, a few other problems came to light within the device's internals.
A couple of these problems were apparent as soon as I examined the device internally, while others became apparent when I rebult the device and tried to use it.
Keyboard:
The R key on the old keyboard had cracked at first, then eventually split completely into 3 parts during use. One part fell away while the other two remained stuck to the flexible plastic backing of the keyboard structure.
As I mentioned above, the cheap new keyboard did not fit the casing whatsoever (the scale of its design was wrong and it was in total 3-6mm longer than the original part).
I cleaned the original board (the plastic layer with the keys, not the circuit layer) in warm, soapy water and removed the broken R key by plucking it off the flexible backing.
I then plucked the 'r' key off the new keyboard and used it to replace the missing key on the old keyboard, with the aid of some 'Bostik Impact' adhesive.
I finally refitted the old keyboard (with a new R key) to the casing and prayed that it would still work.
It did, in the end, but the R key has less travel and tactile response than the unreplaced keys.
---Tip:---
The unresponsive (or over-responsive) behaviour of the keyboard can primarily be attributed to poor design, but the grit and dirt that enters every keyboard known to man similarly affects that of the X1 and worsens the problem.
Removing the plastic portion of the keyboard unit and washing it in warm, soapy water is a good way to at least regain the functionality that the keyboard had when you first got the device.
Vibration Motor:
I saw the physical evidence of the claim that the camera light LED is badly designed and prone to overheating, in turn killing the vibration motor.
In the original phone casing, the plastic housing that surrounds the LED had melted and resolidified over the course of the phone's life and there was minor scorching on nearby components.
The vibration motor for the device is situated directly beside the LED (to the left, while the rear camera lens is to the right) and seemed unable to function with the melted plastic in its way.
I cleared away the melted plastic but the motor still only 'clicked' when I later tested the vibration.
It seems that the motor gets burned out by trying to work when obstructed by the plastic, or the heat from the LED kills the motor internally.
One way or the other, it's dead.
---Tip:---
The recommendation to not use the light for extended periods of time on the X1 still stands, it's worrying to think of how much worse the damage could get if the light were left on longer.
It is an especially worrying issue when you consider that the light LED is so close to the main Li-Polymer battery of the phone.
Broken Side-mounted buttons:
The next problem I encountered in the original phone casing was that of the weak rubber straps that hold the side-mounted buttons (power, camera, volume-rocker) in place.
These rubber components are quite thin and weak, as well as prone to snapping when stressed.
The purpose of these straps is to hold the button in place (flush-mounted) and to provide the spring action and make the buttons return after pressing.
In my case, the strap holding the power button had weakened and the button stopped working properly, while the phone behaved as if the button was being constantly held in.
The phone constantly brought up the "Are you sure you wish to power off the device?" prompt in WinMo.
When I set about trying to remove the old button to replace it with a new one from my pack of replacement parts, the old rubber strap almost instantly snapped!
I replaced the old button eventually, but even now there is less travel in the button and barely any tactile response when it hits the internal switch on the PCB.
---Tip:---
When re-inserting the PCB during re-assembly, keep an eye on all of the side-mounted buttons to make sure that their inwards-pointing nub sits *above* the PCB and is able to reach the board-mounted switch that the button controls!
Incompatible Screws:
Beware that the screws from the phone's original casing do not properly fit the cheaper replacement casing.
This means that you will have difficulty in forcing the screws to fit (and possibly shear the heads off the screws, which is a pretty major problem in a delicate device like this where they will be difficult to remove).
If you force the screws to fit due to a lack of any replacement screws to use, they will likely not sit properly flush-mounted with the original casing, particularly on the front (touchscreen) half of the device; and this may prove problematic for the sliding mechanism.
Additionally, it means that the casing will not close properly, resulting in gaps between the casing and touchscreen as well as gaps along the sides of the device.
---Tip:---
If you must do your own repairs on the device, try to get the official replacement parts from Sony Ericsson.
Buying the cheaper replacements from eBay is a false economy and a major headache, take my word for it!
Malfunctioning Antenna:
When I first rebuilt the phone after repairs I discovered that I could only get very weak intermittent radio signals in places that I previously had full signal strength.
This problem occured only because of incorrect re-assembly by me, but it represents a pitfall that might catch someone else out when re-assembling their X1.
---Tip:---
When reattaching the Antenna unit (the black shroud that sits around the rear camera lens and which also contains the camera LED), be sure to firmly press on the left side of the plastic (where there are visible metal strips in the plastic) until you hear a click to signify that the shroud is properly attached.
Otherwise, the antennae embedded in the plastic will not properly contact the main PCB of the device and your reception for all radio antennae in the device (GSM, WiFi, etc) will be weakened or lost completely.
This problem was caused solely by my inexperienced maintenance of the device, but may be related to the weak-signal problems some people experience with the X1, at a guess.
Ammendment:
------
I may be mistaken on this one! I had originally thought that this component held the antennae, but after further experimentation I've come to think that the antennae may be housed alongside the speaker unit in the other end of the phone. The tip still stands, just to be on the safe side!
Malfunctioning Speaker/Microphone:
During use early in the phone's life I sometimes found that the phone's main speaker stopped working for apparently no reason and that squeezing the casing 'fixed' the problem until it occured again seemingly at random.
Within the rear plastic portion of the casing that forms the battery compartment there is a small module comprising the phone's primary speaker and in-call mic underneath the plastic piece that contains the SE circular logo.
These components make only surface contact with the main PCB of the phone and are not soldered in-place.
In my case, the small copper contacts that extend outwards from the speaker unit had become flattened somehow within the device and no longer reached their counterpart contacts on the main PCB when the device was closed-up.
---Tip:---
Extending the speaker contacts outwards with a fingernail seemed to rectify this problem for me.
Be sure to tightly screw the module back in when you're done, just to make sure of the circuit-contact.
Touchscreen Ribbon-cable:
This problem was mentioned by others in a thread here: http://forum.xda-developers.com/showthread.php?t=561151
I very rarely encountered that problem in my typical usage of the X1, but after my repairs this issue seemed to become exacerbated (probably due to strains placed on the ribbon cable during my reassembly of the device numerous times).
Currently my touchscreen works as it should in portrait mode, but I cannot extend the keyboard, as this causes the screen to still display a signal, but not respond to any touches.
Upon sliding the keyboard back in, the touchscreen is out of the alignment by about 5-6mm every time until I re-align it under WinMo settings.
In an attempt to fix this problem I covered the exposed portion of the ribbon cable with thin insulating tape, in the hope that this would stop the traces of the cable shorting against the metal casing.
Unfortunately, this hasn't proven enough and I have not yet solved this issue.
It looks as though I need to buy a replacement ribbon cable and fix the device that way.
========================
---Other Tips:---
+ Make sure you have all the tools you need.
Replacement parts come with the necessary tools, but if you don't get those you're going to need a tiny phillips screwdriver, a tiny 6-point star-headed screwdriver and a thin, stiff implement such as a credit card or guitar plectrum to open the casing.
I also recommend a snipe-nose pliers and a tweezers for more delicate parts.
Adhesives & Bonding Agents can be useful in certain applications, but use them sparingly (or don't use them at all, to have any chance of making the phone look untampered for warranty purposes!).
+ Don't expect cheap replacement parts to fit perfectly!
They're cheaper for a reason, you get what you pay for, except in the case of the phone itself.
+ Be gentle with all of the components.
The Xperia X1 feels nice and sturdy when it's assembled, but the individual components can be flimsy and brittle when separated.
Everything from the plastic casing to the circuitry inside needs to be handled with care and treated gently to avoid being broken.
That's everything for now, but if I think of any more issues or tips I'll amend this post.
Please feel free to comment with other issues and any other maintenance tips you've discovered and we can build a useful list for people to refer to.
========================
=======
Conclusion:
=======
Before opening my Xperia I didn't really know what to expect inside.
I'm very familiar with computers and I build my own systems as a hobby, but my knowledge of circuit-level electronics is limited and I have no prior experience of manually repairing devices like the Xperia.
My experiences show that some of the common hardware problems can be resolved by the end-user with some patience and the right tools or parts, but one needs to be extremely careful not to end up with more problems than one started with!

=======
Disassembly Summary:
=======
The device needs to be disassembled in the correct order as laid out on this page: http://www.formymobile.co.uk/xperiadisassembly.php
-Remove battery cover, stylus, battery, sim card & micro sdhc card and put them aside.
-Remove the plastic portion of the bottom-rear of the phone (where the SE circle is), using the proper tool, a credit card or a plectrum.
-Unscrew and remove the speaker module
-Remove the screws where the speaker module was
-Remove the covers over the screws at the other end of the phone and then the screws themselves (using the star-headed screwdriver)
-Remove the plastic battery compartment (which also takes the camera cover and stylus slot with it)
-Lift the small black tape and disconnect the plug that powers the camera LED
-Remove the screw in the top-right, then left the black lens-shroud it was holding down.
-Remove the small plug on the ribbon cable at the top-right (this connects the keyboard unit to the main PCB
-Pull the clips around the edges of the green PCB back gently to release it (but do not pull it upwards).
-Lift the PCB gently and (Very) gently remove the orange tape that covers the touchscreen ribbon cable attached underneath, then pry that ribbon cable's connector away from the connector on the green PCB.
-Lift the PCB away and put it aside
-The keyboard circuit and plastic pad can now also be lifted away if necessary.
--- This is where you can stop if your repairs/maintenance only affect the rear portion of the device. Only go further if you need to perform repairs on the front/touchscreen portion. ---
-Remove the four shallow screws underneath where the green PCB previously lay to separate the rear housing from the slider mechanism.
-Remove the four screws in the front portion of the phone, then pry the casing open with the tool/card/plectrum as before.
-The main ribbon cable is attached to a small PCB and some other ribbon cables which are concealed underneath the grey fuzzy foil on the surface in front of you.
-That foil can be removed but it is not necessary to do so unless you are replacing the LCD screen unit, receiver-speaker, front-camera or the ribbon cable assembly itself.
-The Touchscreen component is held down with small grey braided straps at the corners, peel these back to release the touchscreen from the front fascia.
Then do all of that in reverse to put the phone back together!

Personal Comment:
=======
It goes to show that, as many of us are already aware, you must pay a premium price for this phone but it is NOT manufactured like a premium product.
If my situation were rare or I had only one of the above mentioned hardware issues with a new phone I could accept it, but things got ridiculous with the X1.
The build quality is very poor overall and Sony Ericsson should be ashamed firstly for releasing a device onto the market that functioned as little more than a flawed prototype for the X2; and secondly for charging upwards of €600 for the 'privilege' of putting up with its many problems and shortcomings.
I for one, won't be buying any more SE phones.
My next smartphone will be an Android device such as a Motorola Milestone if I ever pluck up the courage to spend that much money on a phone again.

Useful post, but it really seems that the majority of your issues were caused by the imitation housing that you purchased, not by poor SE build quality. Of all the issues you mentioned, the keyboard issues are an SE/HTC quality control problem, I've experienced them as have many. The rest seem to have been caused by the imitation housing. This begs the quesiton, why didn't you just use SE's warranty service? They don't require a reciept or that you be the original owner. And trust me, they are several times better than HTCs warranty service.

I'd hardly call the problem of the non-fitting screws a majority! The rest of the issues were unrelated to the cheap replacement housing.
Maybe my post is confusing, but the issues with the keyboard, vibration motor, ribbon cable, side-buttons & speaker all existed long before I ever ordered the replacement casing!
Some, such as the ribbon cable and antenna were issues that cropped up or were worsened due to my inexperienced maintenance, but everything else was a fault of the build quality of the original device.
The incompatibility of the screws was the only problem specifically caused by the new housing, while its own supplied keyboard didn't fit the chassis, but that was a non-issue since I used the original keyboard anyway.
It could be said that my repairs would have gone significantly smoother if I had bought and used an official replacement housing from SE, but that would only solve the issues of the screws and replacement keyboard.
I put emphasis on the problems related to the cheap replacement casing primarily to warn people away from wasting their money on them the way I did.
I'll edit the original post for clarity.
To answer your question, I didn't use the Warranty service because frankly I assumed they would need a proof of purchase for the warranty (since most warranties do in my experience) and I had bought the device second-hand on eBay.
Secondly, sending the device in for warranty would mean going through the hassle of reflashing a stock rom and SPL to the phone.
Thirdly and most importantly, I wanted to try doing it myself for the experience and potential savings.
Obviously, I wouldn't recommend anyone to try and repair their own phone as I did, but if someone has had a phone sent back to them marked as "tampered" by the warranty service and are left with the options of paying for repairs, paying for a new phone, or buying parts and repairing it themselves.. well that option is there and this thread might help them.
Also, off-topic but I couldn't agree more with your signature. I tried a myriad of fancy ROMs and shell replacements for my X1 but never found satisfaction until I flashed a basic blank WM6.5 ROM and installed PointUI Home2!
Thanks this post helped me out, I suddenly lost my mic, took a look under the hood and found I had the same issue as you, the mic pins not touching. The pins are very weak so had to be careful but it works now!

Glad to help!
Definitely the most thorough repair and tips guide for the x1. A lot of the issues you had are the same as mine. Thanks to your suggestions I got my phone in almost working condition. Now I just need to find a way to get my keyboard working again.
Sent from my xperia x1 using XDA App
Thanks Zurechial for this thorough post. I for one, have been lucky in finding a repair guy (non-SE) who is an expert with devices like the X1. I had a problem that some water/moisture/sweat had seeped in the charging port and I could not get the phone to charge. He fixed it for me.
Now the only problem I face is that the camera is not working, and wifi is disabled. Any tips to get the Wifi working? It is shown as disabled in the Comm Manager and there is no WLAN MAC Address also for it.
brilliant post, thank you very much indeed. I have just ordered a cheap housing off ebay, i know what to expect now
What worries me the most though, is how the keyboard WILL fail eventually ><
The qwerty keyboard is one of the main reasons why i got the phone.
time to snatch back our lives suckers
Apparently, it's taken less than 20 years, to destroy the Consumer Electronics Industries, ability to Repair products, sold in this country. I saw the writing on the wall, in the early 80's, with the first lines of "off shore", throw away VCR's, that were priced cheaper than they'd cost to repair. The theory, if it breaks, throw it away & buy a new one. Who cares if it winds up in a land fill somewhere.
Now, we're up to $500 Cell Phones, with the state of repair being either, unit replacement, or, cannibalization of parts. And apparently no one cares. Is it our complacency or can we really afford as a society, to buy a new phone every time one breaks? God knows we're all desperate, for our phone usage.
It's time to snatch back the repair ability we once had. This is the age of recycling, and the highest form of recycling is repair.
As consumers, start demanding access to schematics, and, access to sources of component level repair parts.

You help me...
I'm almost freaking out when signal on my phone show only 2 bars...
Anyway...
it's for additional information,
use handscoon, it gives somewhat confident and when using tweezer, hold it like using pen (I learnt it when I studied as paramedic) because it will give me strength while holdin it.
AND ask the seller to send housing with screw. I bought 2 housings, from ebay and another hongkong shop. Ebay is s%ck but that other hongkong shop is more fit.

Inspired from members' aging x1 and SESC full of crap... I'm gladly introduce you this full guide that isn't supposed to be exposed. But IMHO, it is supposed to be known by X1 owner.
I think every X1 headset is out of warranty now. While Sony Ericsson Service Centre is always full of crap, bringing broken X1 is absolutely not good idea.
They will asking "faithful" price sometimes the price is higher than the phone itself. Shame on Sony Ericsson.
So please read this guide before you bring your phone to SESC or any Service Centre.

Additional Fixing COMMON ISSUE GUIDE
(thanks to Hkt, triondave, mymailx and russell.eclair (aka rx.eclair)
Taken from local forums and some from XDA-Developers, it's weird some of these methods are never been shared to here...
1. Broken Flex Cable
Diagnose:
a. When slide out, the digitizer (touchscreen panel) isn't working (screen might be working).
b. When slide out, the screen goes blank
c. The mic and front camera buzzing
Repair:
a. FIRST Aid, (It's temporary and somehow fail if you are not skilled, in unkown way)
First method "Tape Patching",
- You can also apply this method preventing this problem while you like using the XPERIA X1 keyboard.
- As easy as ABC, just put insulator tape on the scratch side of flex cable -see blue rectangle with red 'X' inside.
- You may put on another side but it will give a hard slide-out.
Second method "Arc Manipulator", (it's working)
- Try this when you are failing from the first method.
- You can make a very thin plastic with a proper size -see black rectangle with red 'X' inside- and the thick of the plastic should not be thicker than half height of left compartment -see gray rectangle. (I use broken Lego, about 2-3 mm thick and 1x2 cm large)
- Glued it as close as possible to the edge of the 'arc' flex cable -see yellow line.
Explanation: So even the flex cable being retracted while the slider out, the position of 'arc' flex cable is manipulated as closed slider flex cable position. You've got to be sure that the thick of the plastic will not make the flex cable out of the housing so for assurance, try to move the slide locker upside down several times -see gree rectangle.

b. Replace with new flex cable
- search on eBay is the cheapest price. In my country, the price is usually half than local shop but need to wait several weeks.
- After buy the replacement, see the guide to assembling your phone above
How long will it last?
- It's various based on how often you slide it out
Prevention:
- refer to point a.1 (isolate the flex cable) might be useful
- slide it out smoothly (because every time you slide it out roughly, the flex cable being tracked)
- Never / once upon time to slide your X1 out.
2. Unreponsive keyboard
It's very easy to repair it...
[Tutorial] Cleaning X1 Keyboard (Disassemble)
NEVER! follow the threa that is started by hatlo0or, because it is just horrible for beginner and offensive word for some person.
3. Scratching Housing
There's no other way to make it as new, replacing the houding is quite cheap right now. I found that the price varies from 12 to 70 USD.
Which one to buy?
I bought 3 housing for me myself and 1 for my friend.
* I compare those, priced arround 12 USD is better built than priced arround 20 USD.
** the 12 USD is fitted well and the chrome is shinner than 20 USD, the 20 USD Priced is not fitted and quite tricky to assembling it.
*** However the arround 70 USD is the best because it's complete. The housing with 12 and 20 USD have no keyboard but the 70 USD is quite good with keyboard.
Now I am using the keyboard and backplate from the 70 USD priced housing. but for front case and rear case, I used from 12 USD priced housing. As soon as, bought a leather case to prevent it from scratching...
Update!4. Unresponsive Volume Key
Okay, it has been long time that I've been vacuum. After 2-3 years, my X1 has been so terribly damaged. Now, I'm gonna share something else to you all. I dunno know how much people will be helped by this thread since only 20 persons who give comment while 8000 eyes (2x 4000 ppl) read this. But who care? so far there's noone complain.
To be honest, I finally buy another brand new XPERIA X1 from local shop (old stock) with great price because my X1 is what I called "un-help-able"LOL. The problem is unresponsive volume key.
First time, I think it is caused by faulty button but I don't find it wrong after checking up. And after several days' analysis, I found that it is caused by something on motherboard (but I could not determine which one, someone know?). However, the solution is just put something (paper, clip with thickness less than half milimeter) over the USB port (there's a slight gap between the housing and USB port) so it will push down the USB Connector (and Mother board), for unknown reason, your volume key back to normal.
I'm surprised that there are still ones who use X1 since the only person I know using this X1 in my city is me... lol
I just love X1 unfortunately death Sony Ericsson just like White Star Line who make Titanic for becoming so weak.
Thanks for sharing and the credit ;-)
looking good, hope it will be kept up to date
stuck it for the time being

It is named aas digitizer not touch sensor.
It's tricky if you want to separate those parts.
You need only:
1. Micro- scissors (No idea how to say it in English) but razor blade is okay (I always used my husband's)
Just very careful to slide between the display and the digitizer or it might break your LCD as well.
Suggest you to search on youtube maybe there's no tutorial about how to replace X1 digitizer but there's a lot tutorial how to separate 'em on other models.
Just watch and learn from those videos. After you have courage, just try it. But I won't take any responsible for you acts. Because everyone's skill is different, I have no idea on yours. One advice from me is be patient and don't execute any acts until you are really sure on what you do.

It sucks having to dissasemble the phone to clean the keyboard every now and then. I wonder, is there anyway to prevent it from ever happening again?
Thanks for the extremely useful guide mate!
thanks as the aging X1 will surely need this.
Nice guide, but i still with the volume/keyboard problems...
Like some others, i have traced the proble to the motherboard, but i can't find the real cause... I think, it might be some cold solder or a faulty ground connection (this may explain why if you push the usb connector, the keys start to work again)
Great Job Bro
Great Job Bro!! Solved Problem with my X!
Thanks (;
Hi guys.
I have an old SE X1 lying around. The keyboard was not working properly, so I sent it in under warranty, but they sent it back saying I had physically damaged the screen, so my warranty was void.
When I got it back it wasn't even switching on, so I opened it up and found 2 small components broken off the mainboard. I don't know what they were but I've taken a photo of their locations, so if someone opens their phone, could they tell me what they were? It would also be brilliant if you could measure their values. I want to try soldering some replacements on...
I can't post the link to the image as an image, so I'll link it here:

I'd love to get this thing working again, I miss it.
Thanks, Jodie.
Here is the Samsung Galaxy S3 (GT-I9300) Service Manual.
Please take a moment to read the notes and issues about this manual in this post.
For some reason Google didn't pick up that post, so I had to re-post here...
Now, if you are brave and happen to have a GT-I9300, you can still help us by posting some
internal pictures, to verify some issues in the manual. If they are good,
some of them will eventually become part of the SGS3 Hack-Pack.
Thanks and Enjoy!
I will be opening up the phone in the next few days due to me managing to damage the sim card holder section(not holding sim card) So at present i have got somthing putting pressure to keep sim card in place. I have a new sim card holder on order so when it arrives i will pull phone apart and take some pictures.
If you have any advice for me before attempting this please let me know via pm
Do you have any experience in this kind of electronics? I mean, are you planning to replace and solder the SIM card holder by yourself?
If you have not done this type of soldering before, I do not recommend it.
If you do decide to do it on your own, make sure:
You are working on a clean workspace
You are well grounded and not wearing wool clothes mixed with synthetic materials to avoid any ESD.
Have the right tools for the job.(Temp controlled SMD soldering iron + flux and acid-free lead-free SMD solder etc.)
A very steady hand with good eyes!
As for the pictures, keep the environment as bright as possible, preferably daylight. Try to keep your PCB on a bright or neutral background. (Bright cardboard is usually good.) Inspect your pictures and make sure you can read the text on the smallest chips. (The big ones we already know about, its the smaller ones that are difficult to navigate around.) Make sure the pictures are well focused.
Good Luck!
From looking at the pictures I was hoping I don't have to solder the sim card slot in. It looks easily replaceable as it looks like it's just a connector and not soldered
Replaced the sim holder. My camera wasn't good enough to get focus of the smaller chips however it is very very easy to take phone apart. And I guess Samsung are expecting issues with sim slot so they have fixed it using one screw and connected to board using a pull off connecter.
Just in case anyone else is interested the sim holder/sd holder cost me £20, delivered.

Hi guys,
Here is my contribution to da community, hope so it helps.
h t t p s : / / docs . google . com/open?id=0B9lrf7AWQW7ETjRZTkFXb1luN0E
On image 20120616_150200.jpg you can see the region jumpers. The images are of a live demo unit - everything works besides the GSM/3G data. Haven't tested to see if the NFC is working.
The real unit has some more antenna connector. The demo one does not have PBA /printed board antenna/ the ANT102 and ANT103 as well as the capacitors and the coils u may seen them market in red cycles (ANT102, ANT103, C102, C191, L103, L102) there is no room on the MOBO for C192 /or at least I can't find its place/.
Thanks.
^^ Here is the link for above! (Thanks!)
Hi again,
I can confirm that the NFC is working on the live demo unites. According to the original S3 user manual the NFC antennas are build into the battery back.
I still can't figure out what is the "W2" antenna connector for. The Live demo unit has no connector soldered to the motherboard and also lacks the small PCB antenna with the white coaxial cable. Some ppl claim that the W2 is for WiFi antenna, but it is not, because I got great WiFi connectivity tho the lack of such PCB antenna. I can only confirm the WiFi working fine, under "G" type of WiFi networks. The openWRT firmware of my current router has known bug and I can't bring up "N" standard in air, to check if the PCB antenna is for "N" type of WiFi networks.
I also did some testing to see if the PCB is for GLONASS or GPS, and it seams that this PCB antenna with the white coaxial cable is not for any of these services. That's why I think it might be for wifi "N" or 3G data/networks. Donno if the 802.11n requires a separate antenna.
^^ Please post a link to a specific image, that clearly show the connector(s) you're talking about.
Hi I have a live demo unit to, so I think I can help about this =).
I can't show you the mainboard back because I' m new user... xD
I don't really know what you mean with NFC (sorry, I'm not really good with english)
But
W1 is a GSM external antenna conection
W2 is a wifi external antenna conection
And the white wired antenna is for wifi to.
After thinking a lot, if you conect an antenna to the GSM antenna conection (external or the internal lacked in Demo unit) you probably can't use phone function.
That function probably was crippled by software or because demo units don´t have imei maybe o.o.
The only thing I need to try is to connect a microsim to the phone
No one has any insights ???

Samsung galaxy S3 i747
i have a Galaxy S3 SGH-i747m that has been water damaged and given to me so i could try and fix it. I can take pretty much any pictures you want, have openned the phone a couple times now to try and clean it up.
My problem is that the works well, it starts up, unlock the screen, plays sound...but the screen is off. Now at first when i was "playing" with it the screen would flicker on and off to show me the battery charging logo when it was plugged in. I've cleaned the phone and all flex connectors with some products. the phone still turns on and works but my screen is off. It detects the touch since i can unlock the screen ( it plays the water sound when i slide my finger on the screen) and speaker works when i boot it up (little booting sounds).
I was thinking there might be a small fuse on board for the screen backlight and that could be blown. I was also thinking my battery might be damaged and is not giving the phone the right voltage to the right connectors or something so i have ordered a new battery on ebay (under 4$) and am waiting for it.
Anyone has an idea to some specific things i should be looking for ? only thing haven't disassemble is the digitizer from the framebecause doing so would surely break the glass. It bums me up a bit since there are some electronics behind the frame that could have been damaged by the water that i couldn't see.

check if you can see anything on the screen, use some extra light, torch for example.
if so - then its more likely that the LEDs in the display panel are damaged, since it flickered, as you said. also could be the driver circuit for backlight. Clean connectors for display panel, use magnifier, or better microscope to check for corrosion. use IPA to clean or scrape off the corrosion.
also - maybe this is not the right place to discuss this.

I don't have he white antenna coaxial cable neigh the PCB antenna board that this cable is connected to but I have WiFi.
Could it be for WiFi N(150Mbps)?

I have identical symptoms with my i9300.
1. Water damaged
2. Dried in a can of rice etc over several days
3. Cleaned under sim card, lots of debris there, looked scorched, I cleaned with alcohol and a brush in an ESD protected environment.
4. Re assembled, the display briefly flashed on, and showed the expected "Battery is low, an d No Sim Card" then powered off.
5. Now after charging the battery and emplacing my sim card, I hear the proper musical tones when the phone boots but the screen doesn't light.
Where you able to get the screen working?
I am going to try a more throughal cleaning and I will try viewing the LCD under a more power full light.
I too worry that just getting the LCD screen replaced might not work; the screen may be fine but the mother board LCD power supply might be at fault...
I will keep you posted and keep an eye on this forum to find out how to fix this.
This thread has served its main purpose.
OT discussions are prevalent.
Thread Closed!
Warning: These MODs will void your warranty. You will have to open the device and leave traces behind by performing them. Only perform these Mods on your own risk, if your tablet turns into a brick after or tries to conquer the world, it is not my fault !
As many people know, the Nexus 7 ( 2013 ) has some serious issues. Some devices might show next to no problems at all while others are barely usable.
The Mods I´ve come up with help to at least make the tablet usable again since the manufacturer saved too much $$$ for these devices.
Improving the Touchscreen performance and fixing the grounding issue:
The Touchscreen controler is way too sensitive and the connector cable leading to the Touchscreen acts like a antenna. In order to suppress interferences, it requires a shielding.
I know that some people try to flash other Firmware in order to improve the response but this is not how you can get rid of the problem permanently. These extra Touchscreen Firmwares might decrease the sensitivity and make the Touchscreen usable, not more or less.
Material needed:
- Some Aluminum Foil
- Some adhesive Tape
- Some thick piece of paper ( optional )
- a multimeter device ( optional )
- conductive pads ( optional )
Basically you need to disconnect the Touchscreen connector, attach some thick piece of paper between the cable and the battery ( only optional since this method only adds some extra insulation and insures a even tighter fit of the cable ), attach some Aluminum Foil ( make sure to fold it many times since you need many layers to make it stable ), wrap it around the cable and fix it with stripes of adhesive tape.
This is how your new cable could look like. The open copper spots on the Touchscreen cable are connected to ground; by attaching the aluminum foil, it will also have a connection to ground and shield the cable against interferences. You can check the proper connection with a multimeter if you´re not sure if you have a tight connection.
I also attached a extra conductive pad on top of the connector to ensure a even tighter electrical connection.
I salvaged these conductive pads from junk devices
After having performed this Mod, I never ever had any trouble with my Touchscreen controler going ape-sh*t after a while or not reacting when the tablet was laying on my table and only being touched with one hand only ( also known to other people as the "grounding issue" where you need to touch your Tablet with both hands ).
Audio buzzing issue:
My device also had another issue where I could hear a buzzing noise while using the headphone jack without playing any sounds at all. I could only fix this ground connection issue by bypassing it with a extra trace of conductive ink.
Material needed:
- conductive silver ink
- conductive pads
- adhesive tape ( optional )
This is what I did:
You will need a multimeter to check if the connections are ok and also attach some extra conducting pads.
Safety first:
If you´re too scared about risking a short circuit, you can attach some adhesive tape :
My device is working without any flaws now and I can finally enjoy it like I wanted it to behave when I bought it in 2013..
Happy Modding,
I also wanted to mention that the grounding error when using the headphone output, without listening to music for a while, seems to have vanished too.
I used to have a buzzing noise when not playing any sounds at all, after a while. Maybe the parallel ground connection prevents some internal interruptions, messed by a faulty PCB design.
edit: removed
Very cool. I'll give this a try over the weekend; I'll have to get that silver pen first. They cost a pretty penny here in Singapore.
edit: removed this one too
Sweet. I'm doing this asap. I absolutely love my Nexus 7 but the touchscreen just drives me crazy. Terraria is my favorite game and controls are just insane. I get multiple inputs often. Character is running all over the place, turned the wrong way. I tried to play a FPS a few days ago and that was a complete joke. I've done the touchscreen firmware flashes and reseating the cable connections and both help alot but still doesn't stop the frequent spaz fits.
So you did both steps; added silver trace to the backplate and wrapped the cable in foil...?
I'm assuming the silver trace didn't work since you continued working on it. Do you recommend doing the silver trace or just the foil wrap?
A video would be interesting to just show what connects to what. Video is also easier to make out what is what.
edit: removed this one too. It seems that there is not any demand for mods like this.
Just wanted to report that I placed a 2×3 strip of twice folded tinfoil underneath the two cables running down the back inside my nexus. I made sure the left and right edges of the foil were touching the metal bracket before I put the back cover back on. My issues with a dead screen have disappeared. It had been happening more and more over the past 2 months, maybe 10-12 times a day. I was close to getting a new device. Glad I didn't!

I´m glad the shielding did the trick for you
I removed the posts because the Mods require you to not only open the device ( which is easy and can be done without leaving any traces if done the proper way ) but also perform changes which will leave marks behind and void your warranty for sure. If you are a older user who owns the device for 1-2 years ( and doesn´t care about voiding the warranty ), you might want to try them.
But I guess that most people here might be afraid in the end to modify the device like I did. XDA is a platform for software enthusiasts and I´m not sure if hardware-mods really fit here.
But if there really is a demand for fix which require you to do more than just eg. playing with ADB around and flashing other Touchscreen Firmware or simply open the device and pushing a connector ( while wearing gloves so you cannot leave any finger prints on the copper foils ), I can reupload a short description

Well, a mod is a mod. Does not matter if software or hardware. A simple warning for warranty risks should be enough. It's not any more dangerous than installing Cyanogenmod or achieving S-off on HTC devices or bacing up DRM keys of our Sony, yet their inventors think giving you the warning on the OP is enough.
For the same angle, it's l logical that you advise people to use gloves, etc.. to hide any evidence of interacting with the device's inside so the warranty remains..
Besides, same rule as rooting still applies; if one is afraid or not know what to do clearly, then one should not do it.
People, like me, who lives in countries where the warranty is not honored properly because most of the tech companies has no honor at all, most likely would prefer a self-made solution rather than trusting the warranty companies -which is not the device maker company but a local one- and waiting for weeks.

Hello,
I am going to be buying a used Samsung Note 4, specifically: N910W8.
Is there anything specific I should look for in terms of functionality, or common issues this device might have?
Thanks

There are no common issues with the phone. However if you are buying used phone you have to look for these things:
Fist of all, if someone is selling his/her phone, find out the reason why selling, there might be 2 reasons, faulty phone or he/she is upgrading his/her phone.
Phone's Condition --> external condition (such as screen has scratches or side scratches etc.)
Camera: Check Camera is working fine - both front & back ( take some pictures)
Sensors: Check phone's sensor is working, some of the phone's sensors sometimes not working. For Screen / Sensor and other software related functionalities you can dial this number and check sensor, phone's color and screen, if broken internally or not. (*#0*#) - dial this from Samsung phone dialer.
Check Speakers are working fine, make call and check both the speakers.
Regarding Software related: it depends upon the ROM, which ROM you are running on your phone. If stock ROM, phone should be working fine, if he has ROOTED his phone and running custom ROM, then you will find some bugs in custom ROMS.
There are no such software related issues with all Note Series, they are awesome phone.
[*]Also, check if phone is repaired before or not ( you can open the back panel (battery door) and check the screws, if they have scratches then phone was opened and repaired.
Battery: Check the battery, I will tell you the procedure: take out the battery and put it on table & rotate it clockwise or anticlockwise, if it's not rotating, means battery is OK, if continuously rotating, it means battery dead, or about to dead, you need to replace it.
This is what I knew, & I have shared with you.
Good Luck!

test it with a sim and sdcard both inserted.
some note 4's may seem fine, but will suffer freezes, crashes, reboots, and boot failures when both cards are inserted because the motherboard is dying.
make sure you swipe it completely so you don't get busted with somebody else's dirty/illegal porn LOL
