8525 with a missing part

Can someone help me identify the part that is missing from the case of my 8525? If you are looking at the back of the case, the silver cylinder thingy that fits in the opening on the bottom right corner of the case is missing. I'd like to know what this piece does and if I need/should replace it.
TIA for any help!

Mine came the same way from AT&T. I always assumed it was for a Hermes feature AT&T opted not to include in their model, similar to the second camera.

Your stylus is missing
Easy enough to buy another ....

Not the stylus hole... the OTHER side
The stylus fits in the hole on the left side (from the back of the 8525), I'm referring to the hole on the RIGHT side. I believe it is usually covered with a silver circular thing.

That silver ring is nothing more than a place to attach a lanyard to give it it's fancy name. In other words a hook to clip a carrying strap onto if you want one. HTC supply a short wrist lanyard that clips onto the ring - other suppliers I don't know.
You are really not missing anything - with many phones the strap is an optional part.
This sort of thing:

Many thanks Mike (though, secretly I was hoping that it was a missing antenna attachment that would explain why my reception lately has been flakier than a stale croissant)!

You MAY be suffering from the signal flipping from GPRS to 3G. If you get dropped calls and high battery drain, you may want to select GSM Band only in:
Start>Settings>Phone>Band. (Change from Auto to GSM)
(Some branded models do not have this option)
I stress IF you have this problem. BUT it may be worth a try just to see if things improve. If you do not have the option then do a search on Bandswitch or Commmgr.pro

EDIT: By the way there is a place to attach an external aerial under the round rubber pop out cover on the back cover.

Replacing the magics coverings

I am a proud magic owner but as some users have found out like me, it is a slippery fish when it comes to its glossy covers. At first I did not use the slightly camp white leather pouch the magic comes with and now I am regretting it.
The phone has now acquired some bumps and scraps. I thought to my self I would replace the phone covers. So I ordered some on the bay and got them sent to my office.

I hunted down the service manual for the phone. (If anyone is looking for this I have it uploaded here).
I merrily went to work disassembling it bit by bit until I came across a slight problem. Now I have uploaded pictures to illustrate my woes.
First the battery cover was completely rubbish, the brushed steel plate that surrounds the camera was dented and also had the metal grate missing which usually covers the speaker. This was not the biggest worry however.
When I dismantled the phone I got to the stage of separating the the front cover from the middle part of the case. Now as you can see on this picture on the back of the mid section of the case there are two white label like stickers which have gold contacts on the inside.
There are more of these labels on the antenna at the bottom of the phone also. They make contact with gold contacts on the phones main board. I assume the bottom antenna is the gsm antenna and the the contacts on the top are for the gps. I could be wrong though this could be the other way around.
The problem is these label type contacts are not present on my new case mid section as I have shown here in this picture.
Has anyone else had any experience with changing the covers on this phone. Or if these contacts are important or even if its possible to find these labels so I can fit them to my new case.
Cheers for any help you can give me, or if any of this info is useful to you also if you are in the same sticky situation.

bumpity bump!

you could try contacting htc, maybe someone could be friendly enough to point you in the right direction. also email the vendor you got the parts from and say the housing is unusable. I ran into a similar problem with my g1, which ended up having the housing all jacked up.
Sorry I can't be of more help.

Thanks for your help, I will see if I can find out anything and post my findings.
Vale

Just curious, have you tried removing the stickers? Would they just rip apart? Is that the only complication?
You might be able to find a bricked/waterdamaged magic and change the housing without all the drama.
hey check this out too, it may help:

External antenna ipaq hx4700

Connected external antenna to ipaq hx4700. Antenna was from a Belkin Mimo router that had the right size connector (very small IPX connector)
First removed existing connector/wire on wifi board that leads to onboard antenna, then connected external antenna wire to board.
Antenna was omni-directional so there was not much difference in signal. Might try making a directional parabola to fit around the rubber ducky and test with mini stumbler.

DIY BGA RAM upgrade...hmm, now where did I put that toaster oven.

That Chinese site "translation" says:
The ninth step, the new memory chips placed on the chip welding position, alignment solder joints, is very simple, because the chip is surrounded by a white frame, as long as the alignment position on the list.

I'm surprised how much space there is btw the spots on the BGA chips.
I wish I had a rework station. Has anybody else tried this? I know about PPCtechs, I'm talking DIY.

Sorry maybe I misunderstand, are you Yanzeyuan? If so, great write up over there! I wish I could read Chinese.
Welcome to xda-dev!

If anyone's interested, I found an excellent site with alot links to technical info on the hx4700. It's in Czech so Google translate. Links to chips, antenna, etc. Best tech info on 4700 I've found so far.

Replacement I.C
What is the number printed on the dead bug?
It might be a 'house' numbering system used by the Mfr., or it coule be the I.C maker's nuber, such as: LM324, which is a quad op-amp.
Try sourcing from parts suppliers online, such as Mouser, Newark, Phillips, National Semiconductor and so on.
I can try helping you identify the defective component if you can take a pic of the part, showing all markings, then attempt to track down a sutiable part as a replacement/direct drop-in.

If you already have the schematics, you may find the part number in there.
otherwise compare to THIS post. Otherwise look in:

USB points are damaged. I tried to see and solder where they are placed - but no seems no luck
Please, can you give me the closest points, that I can use as solder points for USB DATA? Maybe, schematics or diagram?
I found pinout for processor - but... it's too HARDCORE to solder to processor points

These images worth more, than any words. I needed just last image from that site to understand everything.
I will try to gather all information to some kind of post.

There isn't much in the text and haven't done it myself, but I'll translate that text from the site.
[photo on the side]Hello,
I'd like to show you few photos from replacing, or more like fixing a torn out USB port.
The phone came to us with symptomps of not charging, and after opening it we saw this:
[first photo]
As you can see, not much from the port was left. Torn out GND fields /*not sure about the translation*/, broken - torn out signal fields /*again not sure if fields is a good word*/ of the socket...
[second photo]
...quick preparations and let's begin:
[third photo, zoomed in]
This is how the board looks after initial preparations. Torn out ground fields I had to replace by stripping soldermask, so we could solder the new socket with some stability
[fourth photo]
The holes in the board are cleaned out, the next step was to tin the entire ground field and soldering the socket...
[fifth photo]
Of course the phone can't be charged yet, nor it will communicate because the socket is soldered only to GND. All we had to do was to connect to the signal lines...
[sixth photo, zoomed in]
And now let's test it.
[seventh photo, with HD2 connected]
After testing the communication and charging, the socket was covered with glue and left to solidify. Without glue, the port would probably last about a month because of the weakened board from the last tearing out. After solidifying the glue is a protection from tearing out and lets us enjoy a fully working phone

Thanks Spaqin, that seems a very good translation & far better than google could do. Use of field may not be best choice but certainly descriptive enough & works for me. Have saved your translation & the images to a word doc as could be good reference archive for anyone doing same repair in the future as more repairs on mainboards are a necessity due to age of device & lack of easily found donor boards. Many thanks ...

On a second though, 'area' instead of 'fields' would be probably better.
Glad to be helpful though : )
