How to remove the backcover?!

In the beginning I had a lot of trouble to remove the backcover of the HD.
Now I find out that when you press down both fingers simultaneously at this area of the back, the release is very easy!
Maybe for the experienced users it sounds simple but I hope for some users could it be a great help. See attachment!

I just hold it at the bottom and push with finger through Camera cover

I usually just bite mine off.

?? Why so complicated?
I hold the HD in my hand with display downside - Then flip the cover upwards with my thumb (right under alu-cameramount)
I don´t see a problem.

I always disassemble the phone from the front (screen-side) until I reach the battery...

Your dentist will love you for that

great post with good photo!-found my own way but a noobie will break his head (or hd glass...lol)

what's the big problem? i dont need to do anything apart from sliding it out, and when the latches are out, pick the back cover up. done...

hey, thats the best, thank you

I just use my palm, press it down and then forward in the same motion, it would just slide off.

[CLOSED/G2] Teardown

Here we go

Well best of luck and I WILL be keeping up with this !!!

Subscribing lol

holy crap, already? Subscribed...

would love it if you could check to see if you see the nand chip (probably a square flat pc, soldered on one of the boards) and if it sez "SEM04G" or "SEM02G" on it
that would resolve the issue on internal memory
also if you can take a shot of what is serving as a spring on the Z hinge -
tks in advance and definitely subscribed

Wow, OK.
Why?

not necessarily - in fact I believe there has to be a spring employed - take your phone, hold it so either end is facing straight down (not one of the long edges down) -
then open the screen all the way, start to bring it back like you're closing it, and about 1/3rd of the way from full open, a spring brings it across the center point and nearly to the 1/3rd from fully closed position. No gravity in effect there -
probably isn't much of a spring, but it doesn't need much - a flat strip of plastic that the end of the hinge rubs against and bows out as the screen travels toward the center of it's open/close arc. at the center of that arc would be the max point of bow.
there's another way to do it, but with the limitation in depth, that's how i suspect their doing it - i could be wrong on the 'how' part, but there is a spring capturing energy from the screen as you open it - as the above demo proves

Well, if we can get proof that it's not a 4GB chip like T-Mobile's claiming, they won't be able to refuse returns/exchanges.

Pretty sure the design is based on pendulum swing.

Salute for this astonishing attempt

One hinge is easy the other is not. The one up with the copper strip (which must be pealed to reveal another screw) is a *****. The mobo is very thin. Will try again tomorrow after I have fun upgrading vCenter servers at work.

Post hinge-fix video!

A lot of people have been asking for a video of the end results - here it is!
LOL - I notice the audio doesn't quite match up with the video, Deal with it
Repair materials:
Currently the 5 pack of springs is out of stock - I ordered the 10 pack:
10 pack of springs
Small Phillips Screwdriver
Set of Safe Open Pry Tools
Void stickers for the squeamish

Wow!! Your hinge looks amazing! I just ordered the t5 screwdriver kit. Once I receive it, I will be attempting this.
I still need the springs, but I'm debating on ordering the 10 pack or not.

I wish there was a cheaper spring solution, I stretched mine, but it's still kinda loose. I don't have the $6 to spend on a spring, I had to search for change to get a T5 bit from Ace Hardware, and that was $2

Just a little update - after a day of full use, the phone seems more solid with the keyboard CLOSED; No wobbling at all. It really does feel like a one-piece device until you slide it open, and the clicking sound that the sliding makes really makes it feel good in the hand

Wow thanks for doing that and providing a link to the parts! My only gripe is that to get all the tools and parts, it will cost about $38. I wish we didnt have to spend that to get the phone to operate the way it was intended. Not to mention having to risk the phone not working because we had to take it completely apart.

Damn I want to just tighten the damn spring I have to freaking frakinstin my hole phone to just tighten up a few screws.
F%ck*ng tmobile why must you make some great phones but do **** work on putting them together lol.

The wobbling screen bothers me way more than the loose hinge, so much that the hinge doesn't bother me at all. I just don't understand why the screen can't sit flush to the base.

So, yeah, smallparts.com is out of stock on both the 5 pack and the 10 pack of the springs. Anyone here willing to sell me a couple of their springs? Please toss me a PM.

Anyone take the speaker out of an LG WCP-700 yet?

This is a picture of a circuit board from an LG WCP-700 Qi charger. It makes a very annoying beep, but I can't figure out what is making it. My best guess so far is the part labeled 331. Any help would be appreciated.

Is the beep that loud? If you find out, be sure to post it here. Mine is on it's way.

That looks like it. I'll certainly take mine out when it arrives in a few days, if you are too afraid to yank it wait and I'll let you know how it turns out.
I'd rather have a dead charger than a loud annoying one

Might want to check this out. Someone stated that they took it out and it's dead.

I have the same question, I got the case open expecting this to be easy but I'm not 100% sure what to pull off the PCB. I think you are right that it has to be the part labeled 331. There is just not anything else that it could be.
That said I'm not willing to pull it without some confirmation. Maybe somebody here with more EE experience can tell us for sure.
I don't get my nexus 4 until tomorrow, maybe once I have it I can get the charger to beep and listen for where the sound is coming from.

Apologies for being slightly OT (although I'll be looking to do this when I get mine).
I'm struggling to find a supported voltage range in any specifications for this pad - I'm UK based and need either an adaptor or convertor depending on the range.
Could someone who has one let me know what the specs are please?

How did you get it open??? I've been trying for a week now and have all but ruined the bottom ha! A "How To" would be appreciated!

The 4 little rubber feet on the bottom pull out and there are 4 small Phillips screws underneath.
I had to use a small screw driver to pry up on the feet, it felt like they might rip but they all came out undamaged. Once those screws are out the top and bottom are still held together by a couple of snap-tabs in the middle of the long sides. I was able to get them apart with a little prying and again nothing broke even though it felt like it might. The PCB is held on by 4 obvious Phillips screws.
Sorry I don't have any pictures and can't take any until after I get home from work later.

OK, mine is different then... I got it from Amazon and its a Verizon one and the bottom is all one solid rubery unit. I saw the 4 posts with screws when I pry it open but couldn't get to the screws.
Thanks!

Instead of pulling it or jacking up the PCB trying to disconnect, could you maybe just drown the thing in some sort of epoxy? if not muting it, may at least muffle it some

Check the ZENS Qi wireless chargers, no beep and work great!

I've tried putting my finger over different parts of the PCB and the letting it beep, including "331", and nothing I do lessens the volume. That's why I'm baffled on what part is the actual speaker.

The part labled 331 looks like an choke/inductor to me. I wouldn't remove it...
edit: do you have a picture of the other side of the PCB?

The only things on the back side of the PCB are the two LEDs at the top. I am beginning to think that the sound is coming from the coil itself, like it is performing double duty as a charging coil and as a speaker coil.
BTW, I got my phone today and can confirm (as has been said elsewhere) that this charger works perfectly for charging the nexus 4. Well... expect for the loud beeps.

Awesome, turns out the plugs were there the two I had tried to pry out tore making me think they did not come out. So, now just to figure out where the beep is coming from!

black XL with red accent power button

Why? Why not ?
Turns out the buttons are not really attached to anything. Pulled it out, removed the black coating. Used red touch up paint and Walla

I didn't even have to do that. Just used my thumb nail under the bottom and it came right out

Did mine. Let's see how long it last but it looks really good.

Looks good but no way I'd rock this thing without a case.
Even with cases I can destroy phones with my Butterfingers, lol.

Wait, so you literally just pulled the button off and then had no issues popping it back into position? Nothing broke?
If it's really that easy, that means we could buy a spare colored button from a parts site, like the orange button from the Clearly White variant or the green button from the Kinda Blue variant and pop it on.
How has this not been discovered, previously?

That's correct. I put my thumb nail under the bottom of the button and it popped right out. If you do it make sure your over a table. I didn't expect it to be so easy and it went flying. Almost lost it.
The button it's self looks like it's made out of metal but the back looks like plastic. I had a little bit of a hard time getting it back in but not overly hard. Don't think it matters which way is up

It matters. The clip that locks it in is offset. Only goes in one way.

Maybe that's why I had trouble. Just thought it was my fat fingers trying to mess with a tiny button. The first time I put it in it didn't go in right so I pulled it out and dropped it. The second time went right in.
