Figure 1​
First of all remove the back cover (battery cover) of the phone using a safe open pry tool. Carefully insert the pry tool between the edge at the back of the phone as indicated by the arrows in figure 1 and pry the cover off. The battery cover should come off quite easily.
Figure 2​
Remove the battery and the SD card from the phone as well. To remove the SD card you will need to pop the tab first at the location shown in figure 2 and then take out the SD card. You may use a pair of tweezers if you find it difficult to remove the memory card with your hand.
Now in order to remove the back-frame of the phone you will need to unscrew six Torx screws. Using a T5 Torx screwdriver, remove these six screws from the locations shown in the figure 2.
Figure 3​
Once you have removed the screws you can carefully pry the back-frame off using safe open pry tool. Insert safe open pry tool between the edge that separates the frame and the body of the phone and run it along the sides to unclip the clips. The removed back-frame will look similar to the figure 3.
Figure 4​
The next step is to remove the mainboard (logic board) from the unit. In order to remove the mainboard you will have to unscrew a Phillips screw first and then detach three ribbon cable connectors.
Remove the screw first using a small Phillips screwdriver from the location shown in the figure 4 by a small circle 1.
Disconnect the three ribbon cable connectors using safe open pry tool at the locations A, B and C in the figure 4.
Figure 5​
The mainboard will now be released and you can take it off from the phone assembly and put it aside.
Lift out the camera from its location indicated by orange arrow in figure 5 and then carefully pry up the ribbon cable which will be glued at the back of LCD indicated by gray arrow in figure 5. Note that you need to lift up this cable from its colored end (which you have disconnected from the mainboard) and then pry it off from the back of LCD. Do not pull it off completely from the unit because it is a part of glass screen (touch screen digitizer).
Using a safe open pry tool, carefully pry up the front glass screen from the unit. Note that the glass screen will be adhered to the unit all along the sides with an adhesive material and you may have to use a hot air gun / hair-dryer before prying up the front glass screen.
After you have the glass screen digitizer completely pried off, gently lift it up from the unit because you will have to run the ribbon cable through the gap to completely separate it from the assembly.
The HTC EVO 4G is now disassembled and you can replace the damaged part(s) with new ones. Reverse the instructions above to reassemble your phone.

Thanks for the support. Glad you found it useful!

i would like to add a couple notes after doing this myself.
1. the volume and power buttons come off real easy and are easily lost. do this work on a table and keep track of those buttons they really do just fall off.
2. sometimes the parts dont come with adhesive to glue sthe glass down and to keep dirt and stuff out. i used silicone for this.
3. the glass has 3 prongs attached to them, these also dont always come with the replacement part but come off the old one easy enough just try and keep some of the sticky stuff on them to "glue" them to new glass
4. use white gloves or latex gloves the new glass attracts dirt/fingerprints real easy and you dont wanna keep wiping it down

Some nice tips, however....
Be VERY careful when using glue to attach the screen, not only can this damage the digitizer itself but it not the correct thickness to create the correct spacing between the glass and the LCD screen. Always use adhesive strips, NOT glue.

I'm having a problem after replacing my digitizer for the evo 4g. It boots and audio works fine, but the screen is completely white (no logo). I checked the ribbon cable for the LCD but it looks fine and is definitely connected all the way. Are there any other possibilities here?

Here are a couple of things you can try: make sure correct part was ordered, and check that all flex cables are securely locked in place.

Thanks this is going to help, now if I can figure out what screen to order with out having to take apart the phone...

I found that out the hard way lol... I used some bonding glue that was all bad, not to mention the spacing was off by a few hairs... But I'm still trying to find the right adhesive strips..

Yes. ALWAYS use adhesive strips. NOT glue. Glue can not only damage the digitizer, but even if it doesn't you will not get the correct thickness between the LCD and glass.
You can find the right thickness adhesive strips here - Adhesive strips for touch screens

Whatever you do, make sure you dont accidentally scrape the LCD screen, super tiny nick resulted in this:

Hey guys
I'm having this issue where the LCD I ordered doesn't fit correctly inside the seat, making it so the glass wont snap in. I can get the top part in, but then the bottom is too high up. I've tried using force, but I know that is a really bad idea. Any ideas? I've got a feeling they sent me an incompatible screen. Although, I did boot the phone while it was connected, and confirmed it to be working just fine.

The HTC EVO 4G has multiple screens. Make sure you ordered the correct screen for this device.

Yep had that happen twice, I also noticed that black LCD film is like those expensive camera lens's where when you touch them, fingerprints, smudges, lint, dust, then they are no good any more!

Be sure to check out our Evo 4G video repair guide which can be used in correlation with this written repair guide.

HTC Legend Screen (Digitizor) Replacement

I have looked high and low for Legend disassembly instructions in order to replace my screen (Digitizer) I finally found instructions on how to disassemble the HTC Legend and replace the screen thanks to allerien's post in the XDA forums 11th March 2011, 07:17 PM. There are no YouTube videos yet that I know of that actually show u how to remove and replace the screen so this is a step by step guide tat will help alot of user's including me.
Thanks Allerien
--------------------------------------------------------------------------------
I fixed my Legend
I cracked the display of my legend and purchased a new one on eBay (roughly 40 pounds) - obviously delivered from Hong Kong but a genuine Samsung (in case you didn't know the Legen's screen as well as most of the AMOLED screens are Samsung's).
Then I used the above information plus some YouTube videos to give myself an idea as to what should I do. The result follows:
I used a hair dryer to heat up the back of the phone (camera and loudspeaker cover). Perhaps I should have been more patient as in the end I decided to use a knife with a very thin blade to lift it and I scratched the plastic and the aluminium body a bit. Anyways - the back clicks in but is glued in addition to that so you have to use both the heat and gently applied force.
Once you remove the back cover (which took me the longest out of everything) you should start removing screws. There's two behind the back cover and six behind the bottom cover (where the battery is). At this stage you don't have to remove all the screws - the bottom two, the one behind the IMEI and the one under the VOID sticker hold the main board but the two screws sitting deeper inside the phone's body hold the front buttons so you may leave them for now.
Now comes the trickiest part so read carefully: the main board is held inside the unibody by the screws (which we already removed), but is also glued right below the camera lens and along the sides. You should probably heat it up as much as you can and for a long time. I decided to do it the hard way. My dislplay was already cracked and it's the most delicate part of the phone so I said "whatever" and used the same knife as before - moved it alongside the screen (pushed it in gently from the front) until there was no resistance (the glue let go). Then I pushed and I heated the thing up and pushed and tried from every angle until finally the board slid out of the unibody. I hope you'll find it easier then I did as it seems that everyone describing it found it quite doable.
Now everything becomes easy-peasy. Remove the remaining screws to put the buttons aside (you'll have both the actul buttons and the tiny board with sensors - the latter sticks to the screen but once you remove the connectors, yu can take it off too). All the connectors are quite easy to remove if you hav a needle or something (just pull them out gently). I didn't worry about noting which is which as ther is practically no way you can mix them up - they're very different.
The rubbery plastic black surrounding of the board clicks in, so once you find the right spots you can lift them gently and take the thing off. You'll be left with the display covered by the shielding from the top and a thin metal board from the bottom. You have to remove two more screws to disconnect the main display plug.
And the final bit (that's where the thread's author had a problem I believe). My display was cracked but the shielding - fine. These two are glued together so I had to find some space for my finger nail and lift the shield. By slowly and gently pulling it apart I detached one from the other - and had to do the same thing with the metal board. Don't forget there's some extra stuff to remove from the back of the display - they're all glued but the glue will remain fresh enough for you to glue them again - this time to the new screen. The same applies to the front shield. I hope you won't let any dust sit on it in the meantime. You should have a screen protector on your new display if you bought it like I did. Remove it now and the display will be happy to stick to the old front shield just as if it was always there. The metal back will also fit in.
Now you can go through the above process backwards - just remember to connect all the connectors.
What I didn't do: I didn't use ANY glue putting the phone back together. As an effect the front shield is sticking out a bit (doesn't sit in the unibody tightly). It doesn't affect the phone itself but it gives you the funny feeling that something isn't 100% right. But I prefer that than screwing something up with a misuse of glue (glue can be disobedient).
The most important piece of information: the phone is working 100% correctly as if it was never disassembled by an amateur. Apart from two scatches on the back, the VOID sticker missing, the front sticking out slightly (less than a mm) and the missing battery slider (which I forgot to put back in and didn't bother to repeat the whole process for the sake of it) - there is nothing wrong with the phone. So if you ever crack you ever crack your Legend's screen - you can try fixing it yourself if you have the courage.
Isn't it possible to just exchange the glass along with with the digitizer? I myself need to replace the digitizer, because mine went quite unusable after an accident with water..
Either way this was a nice guide which i will make use of!
great info my legend has only a broken digitizer so i will be replacing that soon

[Q] Digitizer replacing

Today I aquired a HTC Trophy with a cracked screen.
It was not cost effective to have it replaced by the workshop, so I'm attempting to replace it myself.
Following the MicroSD replacement guide by DominikZ, it's been a fairly simple and straight forward process, but I have now come to a point which I'm not sure how to proceed.
I've gotten to the point where I have the two ribbon cables disconnected, and have now separated the systemboard from the front. The front frame now contains the LCD, digitizer and speaker.
Does anyone have some tips on how to proceed from here?
What about the other 3 (black) screws? Torx 6?

Thanks for the tip Lance The pictures were easy to understand, especially when I don't read chinese.
However they did not cover removing the LCD and digitizer.

The three screws on the back of the lcd casing is not screws. Those are threaded cylinders, for attaching the front with the back.
Hey there
how far have you got with repairing the screen as I also acquired a HTC Trophy with a cracked screen. The phone still works so there is no rush but I need to know what I need to repair this unit?
Hey.
No progress so far. I'm not sure how the glass is attached to the front housing, but I have an idea that it might be glued on from the front.
You may be able to extract the glass from the front by using a hairdryer and something thin, like a razorblade. However I have not tried this yet, so I can't say for sure.
Good luck ;-)
There are digitizer replace videos for the htc desire:
youtube.com/watch?v=sXZqIjtFoAU
If the Trophy is build in a similar way you can see how you to remove the glass at 4:00
You can use a hair dryer instead of an oven.
Hi folks, been a long time lurker, came here after looking for a solution to this very problem, so, nlamer here's how to do it, be warned though it's not an easy repair.
(och, I cant post image links until I have made 8 posts :-S )
see attached photos, i'll prob need to do a few replies to post them all.
1:- Strip your phone down and remove the logic board from the chassis, carefully remove the lock tabs to release the ribbon for the LCD & digitizer
2:- Use a heavy duty knife ( I used a stanley blade ) to slice the adhesive holding the LCD to the digitizer, it's only held round the edges so you dont need to go too far in
3:- Peel back the cracked digi and just slice the ribbon, it's attached to the back of the LCD and your not going to be using it again anyway
4:- The LCD is held in place with the light grey adhesive strips, use a spudger to remove it, just be careful not to put too much pressure on it or you will damage the LCD, in my experience it's always better to have a replacement on standby just incase
5:- A quick check to make sure the LCD is still ok, you never know!!!
6:- On the old digi you will need to remove the three clear plastic tabs at the bottom and transfer them to the new one, these feed the LED's to the capacitive button's on the bottom, they are held in place with some adhesive & are not difficult to remove
7:- Remove all the old adhesive and apply some knew strips, I used 3M stuff here and trimmed it to fit but I dare say there are adhesive kits available on eBay
8:- Do the same to the LCD
9:- Line up the LCD with the marks on the digitizer and press it into place, the digitizer ribbon has a small piece of adhesive to attach it to the back of the LCD
10:- Place the display into the chassis, make sure the ribbons go through the gaps in the chassis and everything lines up before committing to pressing down
11:- If all goes well after re-assembly it should be looking sweet again.
Hope that helps yourself & other's out ;-)
Regards
Thanks for the instructions irepairtechstuff. It is greatly appreciated. I almost have my device wrapped up, and ready to go, but I'm having some trouble with the digitzer.
It seems behave as it pleases, and does not register pushes and swipes as it should be. Any tips on this?
Nevermind the last post.
I cleaned the connector with some alcohol, and now it works perfectly
I just got a trophy, I don't understand the adhesive verry well. I though you had to put adhesive on the underside of the touchscreen digitizer (along the edges of the screen) and on the metal frame, under the lcd or the underside of the LCD, but in this turtorial you see adhesive along the edges of the upside of the LCD?????
HELP!
Is there nobody who can help me?
Try private messaging the users who manged to get this to work. They should receive and email and might be able to come back and look at this thread.

Replacing the digitizer

Since I couldn't find any complete guide for this, I thought I'd start one. My new digitizer hasn't arrived yet, but I already disconnected my broken digitizer.
Yes, it was hard But I think everyone with enough patience can do it.
I can't post images yet... See them here: rockenundpoppen. com/carsten/htcrepair/
1. Pull out your battery, your sim- and sd-card. You need to remove the bezel covering the flash. You can do this with a very small screwdriver at the red points, but you will probably damage your case... As seen in the video, you could push it up from the inside, if you insert something like a knitting needle through the battery housing. But I didn't try that...
2. Remove the marked screws. What you need is a size 5 torx screwdriver. Pull that little metal plate indicated by the arrow.
3. Remove the label on the right side of the phone and pull out the little cirucuit board next to the volume-keys. Now you can remove the housing by pulling upwards.
4. Remove the screws to remove the plastic piece.
5. Under the plastic piece on the left, remove the mylar and pull the connector underneath.
6. Now you can start with removing the broken digitizer... Use your hair dryer to loosen the tape underneath. Use a small screwdriver to lever it up, starting at the top. You can use a bent metal plate to try to cut through the tape. Be careful not to damage the lcd! I ended up removing the glass piece by piece at the bottom...
You can actually pull the connection cable of the digitizer now... You won't break something there.
To attach the new digitizer you need to remove the lcd as well. Use your hairdryer, and start levering from the bottom. Don't be overcautious, you need to use some force there. But: don't use your screwdriver at the left, where the little flex cable is located... I did and I broke it...
I will complete this guide later, I hope it is usefull to some of you!

Figure 1​
Pry up the back-top cover using safe open pry tool. Remove the two (2) screws using the T6 screwdriver located at the top of the phone.
Figure 2
Now you can carefully pry the screen assembly and motherboard from the back housing. It may take some time to work the assembly out of place.
Once the screen assembly and motherboard have been removed, remove the 2 torx T6 screws located in figure 3. You can now remove the lower assembly.
Remove the plastic housing on the back side of the assembly by using a safe open pry tool to carefully unclip the housing.

You can now heat the front of the screen assembly to warm the adhesive. Use a heat gun or hair dryer on a medium setting for about 45 seconds, using quick movements around the outside edges.
Use a safe open pry tool to pry between the touch screen digitizer and front frame, carefully releasing it from the housing. Reheat if necessary.
Carefully release the touch screen flex cable from the back of the screen assembly and feed it through the housing to fully remove the digitizer.
Simply replace the damaged parts with the new ones and reverse the order to put your phone back together again.

You can't and shouldn't need to calibrate the screen. If its not responding correctly / fully check over the connections and install. If its still not working make sure there was no damage caused to the flex cable of the screen.
Thanks so much for drawings! It's very clear
I was thinking of repairing the USB port on my HTC Legend. I think one or two of the 4 pins for USB have come loose, so I was considering soldering them back on again.
Your guide, does it allow me to access the USB ports connections?
Cheers

Yes, follow the instructions in the guide that started this thread, which will show how to open up your device. Complete the steps in order to remove the touch screen (outer glass), and then clean out the dust. However, make sure you have the necessary tools for the repair (listed at beginning of the guide). Best of luck!
I did this on my phone today, because the digitizer was broken, the new screen works fine but the USB does not work, the computer says it's a unknown device, does not matter if i'm in android or fastboot mode and the SD card does not work either the phone does not see the card. Any ideas what can have happend?
Found a thread about fixing usb/sd error but for that i need to have "terminal emulator" but i did remove that from the phone long time ago, and since the sd dont work i cant download a APK either and for some reason Play store is also gone after screen change and the clock was reset, Im on CM 7.2

Bulging Nexus 4? No problem!! (Battery replacement guide)

Hey guys, just had to carry out some Nexus 4 surgery so I thought I would share my experience in case it helps anyone else out...
Has the glass on the bottom of the back of your phone started peeling away and can you notice a definite bulge? (You may have noticed your phone not sitting down flush when it's on it's back and it might have a certain rocking when moving, bad signs...both) Well your battery is starting to die, you need to get rid of it!!
First things first, the default battery in an LG Nexus 4 is the LG BL-T5, a brand new one should look like this :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
As you can see it should be 2100mAh. Although it says NOM, don't try eating it, I doubt it's tasty​
I was able to purchase mine from Amazon UK (Even though it was listed as 1200mAh, that was, of course, a typo), I later found an excellent site for spares (ReplaceBase) which charged less but we live and learn. The battery should cost between around £10-20.
Here's the battery from ReplaceBase UK (No, I'm not affiliated with them in any way )
Next thing you're gonna need is a phone toolkit, Again, I got one from Amazon UK, it isn't the greatest quality in the world but hey, it was only £6.35 and it got the job done.
The most important things you'll need in it are plastic spludgers so you don't scratch the phone up, a T5 Torx Screwdriver (The screws in the bottom of the phone which hold the case together) and a Phillips #00 Screwdriver (The screws which hold the battery connector in). Obviously magnetic screwdrivers would be best but not entirely necessary as long you are careful, gentle and have cleared out a working space.
Other things you will/may need...​
A hairdryer or a heatgun but be careful and sparing with it, low to medium setting is fine.
Some kind of compartment tray to hold your screws, they're incredibly small and won't be difficult to lose, I would recommend one of those pill dispensers you can buy, they're great for holding screws.
A sim ejector pin (A needle or needling pin should do if you haven't got it anymore).
Something nice and soft to work on, like a towel or rubber mat as you'll have the phone face down most of the time and you don't want to damage or scratch the face.
Some alcoholic lens cleaning wipes (To wipe the camera and flash after you're finished, don't want any fingerprints or smears in your photos after you're done I would recommend Zeiss Lens Cleaning Wipes)
A thin cardboard strip wider than the phone.
Care and Patience.
So, Here We Go...​
Remove the rear panel screws on the bottom of the phone using the T5 Torx Screwdriver and keep them safe in the holder
Eject the sim with the sim tray and keep that safe too
Take your smallest plastic spludger (You don't want to go straight in there with a metal one as you'll probably mess the silver surround) and start prising the back cover off, your best bet is to start either where the sim tray was or on the bottom above the usb slot, be gentle when you start if you're gonna start near either of these so you don't damage or split those parts.
When you are prising you want to be pulling the side outward as there is clips all round, not pushing the front of the phone away from the back, this won't work and if you end up trying too hard you'll snap one of the clips, so...gently..try to work the spludger into the gap between the silver surround and the plastic back, there's where the join is, try to work the spludger in this gap and then work it downwards inside and lever the black plastic outwards....GENTLY ...You should start hearing the clips seperating, then start working your way round the phone using the same technique, it'll get much easier as you go on.
When you've undone all the clips, there are no cables attaching the back of the phone to the inside, the NFC ring has contacts on the back of the phone which meet contacts inside the phone so don't worry about removing the back.
BE CAREFUL NOT TO MOVE OR LOSE THE TWO BUTTONS FOR POWER AND VOLUME, these aren't screwed or held in place and can easily fall out and get lost (You can order replacements but you really don't want to, now do you?)
Once you get the back off, just gently push these into their recesses and make sure to put the back somewhere safe but not too far away as we're gonna be working on that again, If you feel more safe doing so, you can actually remove both buttons and keep them in your screw holder.
Now that the back is off, you will most likely see something like the following....ghastly and scary isn't it?
BULGE-TASTIC!
BULGE-ORIFIC!!
Sideboob....I mean...Side-Bulge
More Sideboo.....bulge
Here's the brand new, no bulge, replacement for comparison.
OK, Let's Get Back On Track...​
Undo both the screws holding the battery connector in above the battery using the Phillips #00 Screwdriver, carefully remove them and put them in the screwholder.
Prise the connector off using a small plastic spludger. (again, no need for metal ones, you won't meet much of a struggle with the connector and you might scratch a contact on the connector rendering the whole process defunkt)
Now it's time to remove that nasty old fat battery. (although you'll probably notice it slimming down quite quickly as you go...don't think it's fixing itself and you don't need to go any further, it's not)
There's an antenna cable taped to the battery (you can see it in the 2nd image above), try removing the sticky tape holding it down (I didn't actually replace this as you can easily tuck this cable behind the battery when you're done, just make sure you don't remove the cable from the connector above, although it's easy to put it back on if you do, you just press it down gently until you feel it click into place, for anyone who has installed a wireless card into a laptop, it's almost identical to the antenna connectors on those.
The battery has a metal surround all the way round and underneath it (You can see it easily in the 4th image above), it's glued to this underneath so you're going to need a lot of patience with this bit.
You may want to give it a blast with the hairdryer periodically to try softening the glue a bit but don't do it for too long or too close as you'll most likely shatter the front of the phone. Around 5-6inches should be ok for around 10 seconds at the most, just make sure you're moving the hairdryer the whole time.
You should be able to work the battery up by slowly using your spludger (plastic at first, metal after you get a foothold under the battery) and it will eventually come away from the rest of the phone, again, when you remove it, make sure the antenna cable isn't still attached.
Now marvel at the nasty old fat battery....BOOOOOO!!!
Here's my old battery a couple of hours later...
Looks like it's been on a diet doesn't it? Looks like it might be good enough to use again.....nope nope nope!!
Now throw it away or show your friends and family the nastiness.
Now, Get your new battery (Which should have come in an anti-static bag with plenty of padding/protection).
You'll want to lift the antenna cable slightly out of the way.
I would recommend putting the connector on while putting a strip of cardboard, wider then the phone, under the battery to keep it off the glue, we're not seating it yet. Just get the connector screws back and push down the connector first, you'll feel it clip into place, then put the screws back in, I would recommend leaving some play in the first one until the second one is in and then tighten them up, you don't need them so tight Superman couldn't loosen them again, it's not an elephant we're holding in there and you also don't want to keep going and end up threading the screws cos then you're really screwed....sorry.
OK, Now you can slide the cardboard away from under the battery and start placing the battery down into the compartment, you should still have glue on the back from the original battery, I had a good amount which held the new one in place, if you want, you could give it a quick, sparing, blast with the hairdryer to soften up the glue a bit before you sit the battery down. Make sure you don't trap the antenna cable underneath.
Once you're satisfied the battery is seated nicely and looks flush inside the compartment, apply some pressure on it, again, don't be standing on it or anything, this is fragile electronics we're dealing with
Now tuck the antenna cable down the side of the battery and making sure the connector is still in place.
If you want, you can then put some tape down to hold it in there but I didn't bother as it seemed to be tucked in nice and tight and it won't be going anywhere.
The Dreaded Glass Back Panel​
Now, if your glass back was starting to come away when the bulging battery was in there then you'll want to make sure it is nicely attached again, this is where some pressure, the hairdryer and some patience (and gloves if your skin starts to peel off) will come in handy.
Put the back of the phone face down onto your soft surface.
Then start to use the hairdryer to heat up the inside and put pressure down all around the back, you can periodically have a look to see if it's starting to sit in the mount nicely, take as long as you feel comfortable with during this process until you feel the back panel looks like it should.
Let it all cool down and solidify for a couple of minutes.
Now You're Ready To Put The Phone Back Together...​
I would recommend using the soft surface to work with, put the back of the phone with the back down on this surface, then push the front of the phone down into it, making sure the power button and volume button haven't moved.
Putting the phone back together is basically just what you did before in reverse, you should be able to push the 2 halves of the phone back together, then work your way round making sure the seal is flush, if you notice any sort of gap and it doesn't look like the back is in place at any point around the outside, just use your smallest plastic spludger to push out the edge of the back of the phone at that point and gently push the front inside, you should hear each clip go back into place just like you did when you were removing the back.
Once you're happy all the clips are in place and you have a nice flush join then put the screws back in the bottom of the phone.
Breathe a huge sigh of relief that you didn't completely balls it up.
Most manufacturers of these batteries will likely recommend you charge the phone up for a couple of hours after with it turned off but you can watch the battery level while it's charging and see how long it takes. My new battery was actually slightly less than half charged when I first turned it on to make sure it started. Then I left it to charge fully.
What Do I Do If I Did Balls It Up And Damaged The Back Of My Phone?​
Don't worry, you can actually buy a replacement back (including the NFC coil) and not for very much, the excellent site I linked above actually sells a genuine one for only £18, you'll most likely have a similar supplier nearby in your country who will sell the same part.
The best thing about this is it won't have any of the hair type scratches on it that most of our phones will have.
You could even decide to do this instead of using your original back but of course, the process is going to be the same, although, as you'll notice it doesn't seem to include the buttons, that's why you really need to be careful with these.
Well that's it, if you want to see how my phone was after I replaced the battery (to be honest, the back of my phone was bulging in the bottom third, obviously, where the battery was but the glass hadn't separated a huge amount from the case but enough to be alarming/annoying), have a look below (Sorry for the bad quality but they were quick pics using another Nexus 4 from the household, can't fix the crappy camera ) :
Here's the bottom, you can see the speaker slot and the little feet.​
So that's it, sorry for the "Great Wall of Text", I would have done a video guide but, to be honest, this was the first one I'd done and I wanted to concentrate on it, just wanted to get some pics of the before/after too though. If you have any questions or not too harsh comments, let me know
More Help/Guidance​
iFixit's Nexus 4 teardown, so you can see what you should expect inside the phone, they'll also give you lots of info about the cabling, screws, tools, etc, I read through this page before ordering all the gear and before starting, I'd recommend you do the same.
The battery and rear panel I would recommend ordering again, sadly, this is in the UK but you should be able to find somewhere else closer who will stock these:

Rear Panel (Again, remember you'll need to retain your original power and volume button so be careful with these.

Could a Mod move this to the Help and Troubleshooting forum please.
If the Mods deem this to be helpful it might be an idea to pin it too ( Not trying to be pushy )
MOD EDIT: MOVED :highfive:​
it should be noted that the battery must be OEM or else the phone will detect it as not OEM and will open just in boot loader or show faulty %!
