Destroyed antenna? - Touch Diamond, MDA Compact IV General

When removing the battery cover, below the battery is a sort of black 'sticker'. Because my diamond became wet, I wanted to remove this one, so it could dry better beneath it.
But it got off (it was dark when I did that) but next morning I saw there was copper connections inside! I totally ripped it off the sides , where is seems to go to the mainboard.
Was this some sort of antenna, an anyone a good idea how to fix it again? I got the loose part

Loose Charging Cover

I've had the g1 since launch and the charging cover is starting to get loose. The clip on the left side of the cover doesn't stay closed anymore and always hangs out halfway.
Just wondering if anyone has the same problem and found a fix.
Fix
OK, so I played around a little bit and realized that the clips on the left and right of the mini usb cover are not really used to keep the cover in place.
To tighten up the cover again I used 3 pieces of scotch tape, layered on top of each other, on the long side of the hexagon shape of the mini usb. Make sure the tape is on there well and wont come off too easily. It has worked so far for me, but don't know how long it will last.
If anyone has any other suggestions, it would be appreciated.
I've been contemplating taking mine off.
I took mine off. No need to open a flap to charge now
Had no probs whatsoever since

Battery Cover lose

Hi guys
for a couple of days now my battery cover doesnt properly fix anymore. You know how when u put it back on you have the two golden hooks at the bottom of the battery place on the x1 - it seems that the left one of these two hooks doesnt hold anymore cause it is at that spot that the cover is lose and consequently keeps falling off all the time.
hope this was somehow clear
any idea how to fix this?
I had this issue with the first 2 X1's I purchased. If you cannot get a replacement just simply try squeezing together at the two clip points so that they grip the phone tighter when applied. Alot of people have had this issue and there have been alot of threads created about this, if this is no help then hit up the search bar.
i just slightly bent the metal side flaps inwards lightly to make the little flat bits press into thier sockets better. the gold things are contacts. i'm guessing to detect if the cover is removed or to make the backplate act as a grounded shield. but non the less they don't do anything for holding the backplate in place it's all down to those 2 little flat bits that grab spots on the side plastics

Theory on source of the screen lift issue and possible wedge fix

The washer fix resolved the screen lift issue for many, however I've noticed that something doesn't quite add up. Using the washer fix mysteriously resolves(or partially) the issue of a springy/spongy left screen and the creaks and popping noise. The theory was that the screws was too long and tightened too far with the ends of the screws pushing the glass screen out and pulling the plastic silver bezel back.
There isn't a reason to why the springy screen or strange noises was fixed and neither a reason to what the cause was. Besides resolving those issues some people found it hard to push the back cover back on and still have bulging back covers and also bulging silver bezel. You might get away with this issue by putting washers on the two centre screws and taking out the washer on the top part of the screen. I believe this worked because the height of the screws gets elevated with the washers and pushes against the back cover and denting and marking it in some cases. If you managed pop the cover back on the increased pressure from the screws makes the plastic tabs pull on the silver bezel and warping it (maybe).
I thought maybe the culpit of the screen lift might not simply be long screws. But I didn't understand how the washers fixed it. After looking at iFixit teardown pictures I saw something else that could push down on the LCD unit and onto the screen. On the second picture of step 12 I can see large cut outs in the metal frame and on the back side of the motherboard I can see taped components. I thought it might be possible that the taping left creases and air bubbles on the pcb and the bulging of the taped components looks like it can press on to the LCD unit directly underneath. The cause of the popping noise and sponginess came clear to me now. The popping noise comes from the tape being pressed against it (it could be glue from the screen/bezel too) and the sponginess is probably the PCB bending .
I think what the washers did was lifting both the metal frame and the pcb up and the taped components underneath didn't press against the LCD unit anymore. This created screw elevation for some people and back covers can't fit back easily as I mentioned.
I didn't want any screen lift, bulging back cover/bezel. I thought maybe I can lift the pcb up without putting washers in and I thought of just wedging the pcb against the metal frame right next to the screws. I don't recommend anyone to just try jamming stuff underneath the pcb without checking out the pictures and have a plan first. There are components underneath and please don't push anything too far in. I've tried putting plastic blister underneath the pcb in between 4 screws and next to the 4 pin connector. They are just longer rectangles by the way and I trimmed the ends in the same way as the washer method. However the screen still bulges a little around the centre where I can't put wedges because of the ribbon cable. The bulging back cover problem is completely gone however. I think I will try to put one washer for the screw above the ribbon cable, because I can see that the pcb has a screw hole right under the ribbon cable near that screw. This should lift the pcb a little around the centre. However I'm going to put a thinner washer as I don't want the screw to get elevated too much.
Anyone thinks this theory is rubbish, or have something to add?
EDIT: I report success! Instead of typing out the same thing I will show you with pictures. No idea if this fix will last, no guarantees. I still have a little sideways bulge but my N7 is so close to being perfect now. I don't think I will change anything else for now.
it's from that black foamy piece in your photo....this was mentioned in one of the other threads....

[Q] M7 no display after replacing battery

Hi
I tried to replace my battery and after assemble it back i only get a black display when turning my m7 on.
I broke this little plastic thing from the display cable off (look in attachment)
Is this thing essential for a working display? (i thought i can fix it with a drop of glue)
Should the display work when the backcover is off the device? Because there are some connectors on the backcover....
cheers

Shouldn't have done that, I think you accidentally broke something. I'd send it to a HTC service center. But that's gonna cost you probably.
nah, official repair isn't worth it. The phone is more than 2 years old...
and yes i think i broke something... thats why im asking
You're gonna have to be good with a solder and a couple of tiny wires if you want to revive your phone.

You definitively need this clip to be intact so the flex cable sits firmly in place otherwise you'll have bad contact between the cable and the pins.
If you don't want to send to HTC for repair you'll need at least to send it to your local electronic repair shop so someone skilled with the proper soldering tool (not the standard iron you have at home) can replace the connector. BTW some of these clips must be lifted from the cable side and some other from the opposite side of the cable, so next time use tweezers and apply very light force on each side you'll find from what side it must be lifted.
LCD should work fine with the back cover removed, afaik. Connectors in the back cover are often for antennas but I wouldn't recommend to run the phone with antennas disconnected to avoid damaging the radio chips (reflected power).
If you are from the US, you can easily find this connector on ebay for about 10$. I'm sure it won't be that much expensive to repair if you bring the new connector and the phone already disassembled to your local repair shop.
Btw are you sure its only the LCD? When trying to boot the phone can you here the HTC theme or does it vibrate? Recognized by your computer when connected with usb?
thx for your response
I found an replacement part on ebay but first i have to look for someone who can solder this for me.
When i try to turn it on it only vibrates without a htc theme sound and there is no display reaction.
The other thing i mentioned is that the phone gets very hot in the middle (should be the cpu) where i dont know if it should get that hot.
I have to try the pc connetion again and let you know asap.

I'm not really worried about the absence of HTC sound when booting, if your phone is on silent / vibration mode, it will only vibrate when booting. If your computer does detect it once booted, then I guess the broken connector clip is the problem.

Here is a video about the connector replacement, it doesn't look that hard to replace but wouldn't recommend to do it yourself if you never soldered electronics before. Soldering isn't that hard but you need some practices and knowledge to make good joints. I don't think your phone motherboard is a good candidate to practices yourself if you never did it before. You'll also need a really tiny tip for your iron, probably a type "L", 50/50 solder + some flux. Flux must be cleaned after use to avoid corrosion. The most difficult when soldering on motherboard, imo, is to find the right temperature. If your iron is to hot, you'll damage your connector. If its not hot enough, solder will take more time to liquefy and some heat will be absorbed by surrounding components which can cause irreversible damage.
Easy fix mate
You don't need to replace the connector, I've done this before, it is just the connector clip that has come off and it goes back on reasonably easily.
You will need a good magnifier.
You will need a good light source.
The phone held securely on its side with the socket pointing up.
Some masking tape on the loose part because it WILL go "ping" into the distance if you don't and you will not find it.
Look at the other connectors to see the proper orientation for the part, mark it with a permanent marker on top and at one end.
The insertion looks difficult, it isn't too bad, keep the part nice and straight and the motion is kind of like clicking it down on the ribbon.
Forget replacing the connector, that is 100 times harder.
If you do lose the loose part I have one or two laying around.
Good luck.

Water Damage Screen Cable Fix?

So my nexus 6 decided to take a swim in a pool. It was in for about a min and when it was taken out I took the back cover off. Removed all that I could and let it dry in the sun for a day. Put back together and the screen will go from a soft black and fade to a green then to a white and then off then repeat. The phone does start up and work. I can send myself emails and texts and the alert sound works and when I call it it rings. The screen is unusable though. I took it apart and this is what I found. The screen cable seem to have had a short. Is there any way of fixing these two very small trace wires? Or do I just go buy and new screen and hope for the best.
Have you tried cleaning it with 90% isopropyl alcohol and a qtip?

Looks shorted and burned to me. Never crank a wet phone. This is what board will look like. Probably fried before ever shut down.
Looks like you damaged it taking it apart.
Those traces can be cleaned though. However it could be an issue in the motherboard. Take all removable components off and give it (the motherboard only) a bath in 91% isopropyl alcohol for 5 minutes. Drip dry for a few hours.
Sorry I forgot to mention that I had already put it in isopropal alcohol and cleaned it with a qtip. The traces where not damaged by me. And they are gone no cleaning will bring it back. I guess I will just get a new screen.
Ah! I see now I thought that was mineral deposits. It's fixable, but you need some serious skills. Might as well just get a new screen.
I ordered a new screen and replaced it. The phone looks and works perfect except for one thing. My bottom speaker now rattles and my microphone does not work. I believe it is because I put the main board in rubbing alcohol and it damaged the plastic on the speaker. The bottom speaker is attached to the main board with adhesive and was easily removed. I ordered another replacement speaker. I hope that the bottom speaker also acts as the microphone. I dont think I will put my phone in rubbing alcohol unless it is my last resort.
