So decided to take apart this thing again to try and fix speaker issue I've been having, after the last time I had to take it apart to disconnect battery after soft bricking it (boot loop + holding down reset combo for too long) this time decided to take pics just for a reference in case anybody needs a peek inside to see if they can find anything that can fix an issue on their device without actually taking theirs apart.
So after removing little plastic covers on top and bottom as well as SIM, SD card, and label under bottom plastic, you'll get 4 screws on each corner of metal piece which is where most people have disassembled to.
To further take apart the device there are 5 Torx T5 screws and three more philips screws, remove them and slowly pry apart plastic plate with antenna components
What the plate looks like
And then you'll be to the inside of the device where all the components are laid out
Hope these pics can be of use to at least one person, just in case you wanted a peek inside the device, or if you need to find a certain part. I only needed to take it apart this far to both disconnect battery and to look at the speaker.
To disconnect battery if you soft bricked (hold down reset combo until 3 vibrations and phone won't turn on)
note that our ion can only disconnect the battery, which is the equivalent to a battery pull, but battery is sealed in there quite good, so replacement isn't easy if that's what you're looking for
After you take out all the panels and get to what you see in the third pic, gently remove this cable coming from the battery to the motherboard
Then wait about 5-10 seconds and plug it back in. Gently.
Probably you'll want flashmode so before putting phone back together hold volume down button with your fingernail and plug in USB cord when flashtool asks you for download mode.
The end

Hiya,
my Desire HD got wet in the front pocket of my fleece, not drowned just some droplets of water that got inside the Otterbox case and into the phone. I did try and turn it on before I realised it had got wet, it wouldn't power up.
I removed the phone from the Otterbox and dried everything and tried to turn it on again as there was only very slight traces of moisture apparent. There was condensation and a couple of little drops of water inside. I discovered there must have been enough moisture to short out the battery as there was a little residue mark above the contacts on the inside of the casing. I then noticed the liquid indicators had turned red.
I removed the battery cover and dried the phone gently using an electric room heater for hours, I also put the phone in a bag of rice for a couple of days.
I tried to power it up again after a few days in the rice and it wouldn't start up. I measured across the battery contacts with a multi meter and found the battery was open circuit, so I know it must have shorted. Hoping that this was the only damage I bought a new replacement battery. When I fitted the new battery nearly a week later and switched on the phone, everything seemed to be fine but the display seemed to flash, and as I had a Leedroid rom installed I heard R2D2 chirping and could see the device start to boot up as normal on the screen. Then the display went dark and hasn't worked since. I stripped the phone and cleaned a couple of patches of residue, one of which was right in the lcd connector.
Now when I try and start the phone there is no display, the phone vibrates once when I hold in the power button. Approximately 40 or 50 seconds later I can hear R2D2 making his tweeting noises which always happens on boot up. I didn't think it took so long to hear R2D2 but maybe the phone is checking the file system or something now, and I just can't see it.
It may be that I just need a new screen & digitizer to repair the phone, but I can't tell what might be on the display - maybe it's the phone unlock screen asking for my pin number etc. I can't see any image on the screen, that you would normally see when the baclight is faulty, I have tried to view it with a desk lamp, but it's just black. The capacitive buttons at the bottom don't seem to have any effect, perhaps they are not enabled if it's sitting at the password screen, if it is at that screen.
The l.e.d's don't light up at the top when I turn it on or plug in the charger.
I might have also damaged the volume key switch/ribbon slightly.
What would you do with this phone, any advice on how I could proceed ?
Would it be working just with no display, as R2D2 is squeaking(Leedroid rom has this when the device boots and has an animation of a pc booting up with the post screen) ?
No l.e.d's is a bit worrying and it doesn't seem to know when on charge etc. but perhaps they only work once the phone has booted, I can't remember DOH!
I just thought I would ask, as there are a lot of knowledgeable people on here and it might be possible to save my droid.
Grateful for any help or advice
kind regards

Hi,
I have a Huawei Ascend P6 that had battery issues, battery was not holding charge and was even inflating at the point that lifted back cover so I decided to replace it. I bought the replacement and follow a guide on Ifixit for battery replacement.
After I replace it I powered the phone and started up (sounds and vibration) but screen was dead. I can also hear notifications and receive phone calls (obviously I can´t answer). Has anyone had an issue like this before?
Did you check the clipped cables?
You can hear them "click in"..
Changed a battery myself after a water damage..
Took me some time so pry it out gently cause off the adhesive its glued with..
Damage could be done at this point, when forcing it too much..
But check the clipped cables first..When i remember correctly, the LCD cable is the big one at bottom left..
Not really possible to do this if you wanna put the screws where they belong.
However I just noticed that the case can be removed pretty quick and pain free with just a thumbnail and a guitar pick as long a s you prop the top with the pick, and slide the strong thumbnail all along the non vol button side. I was surprised how easily the snaps popped and the side lifted up. After which it was easy to remove the glass and bulk innards of the m8.
...anyways, when I cracked one of my repair jobs open just now I found an entire ribbon from the motherboard not plugged in. The one on the upper left that come from under the motherboard and attaches at the sisterboard
Anyone know which this controls?
This phone was recieved as a "No power up, no charge" purchase.
Hoping for another quick fix here.
When that ribbon was partway plugged the vibrate bobin continuously went, then a satisfying end to oscillating bobin vibration when I got it in place.
So it clearly has plenty of battery. Yet still refused to turn on even after the 2 minute long press of power+vol up which is suggested throughout the world to solve no power up problems. Also tried the 20 sec power hold then short vol up push followed by 10-15 sec power + vol up hold. Nothing.
I had not plugged it at that time.
Both m8 I opened today were previously opened phones and both opened easily. Planning a usb port swap if I can't get this one to work.
Anyone got any other ideas on getting the battery working let me know.
Actually, to correct this, no guitar pick is needed at all now. I can pry all with my strong thumbnail. The thumbnail is only 1.5 mm. The top is the start point, get it up so it doesnt go back in, say 2mm from back case, then the non volume button side, then the vol side sliding both sides from top to bottom in turn, (you should be able to hear each snapping clip pop out, 4 per side, as you slide. Then the phone body will pop out of the case as easily as a samsung.

take apart the m8 with thumbnail (~5 min) https://www.youtube.com/watch?v=OxbLTptmkKo
replace USB Port without removing motherboard or sisterboard (~6 min) https://youtu.be/6mDh1FM_37k
I have a black screen issue that starts with the screen getting dim, then the next day just a black screen with sound and touch feedback.
Taking the back off and reseating the cables fixes this, but it happens every few months.
Will replacing the screen fix this issue or is there something else going on i need to address?
i'm pretty sure it's not the OS. it happened when i had TW and still happens on LOS.
Do not replace the screen

Don't replace the screen the problem is the ribbon cables. The best solution is to reseat the cables then place a layer of electrical tape to secure the ribbon cables so they do not move when you drop the tablet (accidentally or just setting it down on a surface).

Maybe you have an idea about this? Very perplexing. My screen started getting darker in one corner. then it blacked out. I had already read about reseating the ribbon cable, but the really weird thing is on a reboot the screen comes back on. It has done this several times. Last time, I thought it had blacked out for good, but nope, it is still coming back on after a reboot. This has happened after several ROM updates. I am at a loss.
Same Problem

The root cause of the fading in one corner is the same problem...badly seated ribbon cables. My Note 2014 experienced a faded corner too before the backlight stopped turning on when I woke it up from sleep mode. Fix action was the same...remove the black plastic cover, flip it over and carefully remove and replace the ribbon cables to the display. To prevent future problems carefully use a sticky black electrical tape to help hold the ribbon cables in place. Check the function (push the power button to put the tablet tot sleep then wake it up) before you replace the cover. Good luck!

For those that are interested...here are so pics of the ribbon cable reseating process. I had to do this again to my P600 after a hard drop to a wood floor to nights ago and found the back lighting not working correctly.
Symptoms: 1. Darker spot in corner of display on wake up from suspend. 2. Pressing power button to wake up after tablet put its self to sleep after the screen timed out (turned off display) resulted in lighting of only the soft return and menu buttons and the display back light failed to turn on resulting in a black screen.
The fix action:
1. Turn tablet off and remove the pen from its built in holder.
2. With screen facing up, use a plastic key card (hotel room key or reward card) to go all the way around plastic-chrome border of the tablet and unlock the back cover from the display.
3. Flip the tablet over and lay it on a soft cloth. Carefully flip up the black locking tabs of the ribbon cables (these things are delicate and are easily broken unless you use minimal force). Only the cable on the left can be completely removed (see the first pic). The lower end of the right cable is attached to the display. Fold it out of the way. Remove the cables and inspect ends for damage or debris. reseat the cable paying attention to the tiny locking tabs of the cables, then lock them back into place.
4. Pick up the tablet. With the screen facing you rotate it until the USB port is facing to your left. On the upper right side of the table you see three round silverish dots. These are membrane switches. Press the upper switch carefully with your finger nail (you fill the switch move and make contact). If the screen turns on, carefully flip it over and lay the screen on a soft cloth. Carefully put electrical tape on ribbon cable to hold it in place (see pic 2).
5. Flip over the tablet over and press the power button again to turn on the tablet and verify function.
6. Replace the cover of the tablet. Go around the entire tablet edge and gently press the screen into the cover. You should hear the locking tabs snap as they lock back into place.
Recovery if the screen does not light after replacing the ribbon cables.
1. Unlock and remove the ribbon cables again.
2. Remove the five screws holding the battery in place.
3. Carefully lift the battery out of its position and gently lift up on the wires connecting it to the tablet, the connector lifts up from the tablet to separate.
4. Wait 30 seconds and replace the battery and cables. Repeat step 5 and 6 above.:good::good::good:

as mike suggest, unless hardware issue, reseating cable fixed my similar issue as well.
make sure to secure those cables with the tape so it doesn't happen again.
This! As Mike recommends above! I replaced a failing battery and the unit worked great, but coincidentally dropped my note the next day. The screen was black and I figured it was dead until I read this, figured nothing to lose and opened it back up. I reset the ribbons, taped them down and I'm back in bussiness. I suppose the drop was just enough to lose or unseat the ribbons. I taped thenm in place and all is good. A million thanks!
I read conflicting info on how to open the tabpro. My daughter's TabPro 8.4 is bootlooping. I want to resolder battery connector and possibly replace battery if it turns out to be in need of replacement. Any authoritative answer whether to open from front, separating glass from bezel, or remove the back? Thanks!

To me, the back was the easiest to open. Just use a (plastic) prying tool and start from the MicroSD card slot. By turning the prying tool slightly while inserted, you'll pop out the plastic tabs that hold the backcover attached. Just mind that the tabs are stiffer around the 3.5mm jack and the usb port.
The battery connector is at the back anyway, so once you pop off the back, you have access to any parts you need.
1. I did not compare, but opening the front of 8.4 was quite easy and there was minimal risk to break the latches.
2. There's no need to resolder battery just for to get rid of bootlooping. Use power and volume keys to enter recovery or download mode and do a wipe or reflash it.
3. There's usually no need to open device to decide if the battery needs replacement. What do you expect to find there to make the decision?
I just did this today for my tab pro 8.4 (was not charging and got random bootloops). I followed the vid the link below (I got it from another thread on here but I am afraid I can't find it right now)

Was very easy to do if a little nerve wracking taking it apart ... I just took out the battery and put it back in and it seems to have sorted the charging issue ... Yet to see if it solved the random bootloops, only time will tell ...
