Very risky.. as HTC has sensors dozens of sensors and very complex IC and integration of them..
Very Very need full and good tutorial who like listening to music but cant hear it properly due to socket.

Actually it isn't that risky, as you'll only solder the connections of headphone socket... If you know how to solder then you'll be fine

I would strongly advise you apply heat syncs when doing this, otherwise you can end up frying components near the headphone socket (I've managed to do this before when using old solder that wouldn't melt easily)
Another tip, use the smallest tip you can find for the soldering iron. if all you have is a chisel tip, don't use it. it's too much risk!
lastly, make sure you clean up the old solder. don't mix new + old
I also recommend looking at some soldering guides. it's easy to do a bad solder and make stuff even worse.

Help Me find a perfect Dock Aux Cable for the Desire?

Hey Xda,
For a HTC Desire and a speaker dock, I am really struggling to find a short 20-30cm cable which doesn't have straight plugs at either end.
I have searched and cannot find a short cable with the 'L' plug at both ends...
I think it would be great for everyone who has an iPod dock or any dock with an Aux in to find a perfect 3.5mm cable that is portable and easy to use without port stress.
The long plugs are unsightly and also put pressure on the sockets in the desire and dock, with the cable I have now.
I am not a dab hand at wiring... I don't have a soldering iron.
And on that note I also would like it to hold together multiple unplug-plugs as it is a portable social dock kinda thing, lol.
I can only have the L plug at One end with everything I can find... here is a diagram of what I wish it could be like!
(I have plugged the single L I have in both)

It is really annoying, I just can't find any that are <30cm in the UK!
Even Hong Kong eBay doesn't have short ones!
The shortest I can find is Three Ft Long!
Anybody have any clues on this trail?
Thanks
Create 1 ur self?
Get 2 plugs and the appropriate wires and solder the things together.
If you cant find the appropriate wires just get cheap ass earplugs for a euro/pound/dollar orso cut off the ear plugs and attach a new mp3 3.5mm jack at the end and ur done. This means you only need 1 plug and 1 set of earplugs.
I replace connectors of my earplugs all the time if they fail and they do fail allot XD.

Hey,
Thanks for replying, but in the post it says I don't have a soldering iron or anything, not everyone does lol.
I would rather just spend £2 on a solid cable instead of buying earphones and making something really weak
I wouldn't want to "replace connectors of my earplugs all the time if they fail and they do fail allot" haha
If anyone thinks of a link on a decent cable, please post your ideas in here.
Thanks
soz mate over read it
and about the failing i mean the failing of my earplug mp3 3.5mm jack cauz it gets alot of stress at the point the cable enters the plastic housing of the jack(This happens the first time with the original jack and then i keep soldering new ones on so i can still use the earplugs). This is the cauz of lots of movement inside my pocket when im cycling. You cant realy avoid this stress if u wear your phone inside your pockets of your pants ;-).

That is exactly what I am looking for, lol, but...
It literally in my case needs to be a minimum of about 20.5cm to reach from phone to dock if It's sitting on the dock Haha.
That is an amazing keeper link though, thank you!
15cm is just a little too short haha, fussy days.
Cheers

[Q] How to replace vibration motor

My vibration motor in the Nexus s broke. Now I want to replace it. I'm planning to order this motor: http://www.tvc-mall.com/details/Replacement-Vib-Vibration-Motor-for-All-Samsung-Models-SAMO-SAM/
I opened up my Nexus to a degree where I could see the motor, but I couldn't see how the wires are connected. Do I have to braze the wires or can I just plug them in or how does it work?
Thanks!
Are you positive it is broken? Mine stopped working on me a few times before. I would tap the phone firmly, powered it off and tap again and reboot. Problem solved. Just a fyi

A 15W soldering iron should run you around $10 US.
I highly recommend soldering wires on random scrap if this is your first experience at soldering or you're gonna end up with a mess.
Edit: Or you can cut the wires, strip the ends, twist them together and solder (then cover them with heatshrink/electrical tape).
Should be easier for a beginner to do this than solder on tiny pads and remove epoxy from a PCB.

Thanks, pretty stupid, I didn't think of that. I might not even have to solder at all if i twist them together tightly and then bind them with tape.
riichii, have you managed to do it? I'm positive my vibration motor is broken as well, but I cannot find an exact replacement online. A friend of mine had a broken samsung j700 lying around so I salvaged the motor from it and soldered it in my nexus s, but it didn't work (you could hear the motor rattling, but it wasn't vibrating enough, it was less than my broken original motor). I was wondering if the part you linked was working or not. Thanks

Thanks! Yeah the adhesive has to be warmed up to get loose enough to be able to release screens and such.

[SOLVED] GPS Fixed!!! For real this time.

It's a noise issue with the gps antenna and other h/w on the board (mainly lcd cable.) It can be fixed by insulating the board from electrical shorts (scotch tape in my case) and shielding the board from the antenna with aluminum foil. Not for the faint of heart, obviously you can ruin your phone if not done correctly. If your wondering how much of a difference it'll make lets say my GPS works in my basement, in walmart, even in a multistory business office. I have yet to find a spot where it won't work. Most times it locks the instant it's opened, indoors you might have to wait maybe 10-30 secs.
If you think shielding the whole phone will help the other antennas, it won't I tried. You only have to do the corner that the GPS antenna is located and of course ground it. The GPS antenna is labeled with the letter G on the case of the phone. It's inbetween the camera, battery, and power button. Face down camera up, it's located upper left portion of the phone. Each antenna looks like a black label, please don't peal them off. Phone must be disassembled to perform this mod. I will not tell you how to take it apart (google it) nor be responsible if you break it. If you don't understand the concept of shielding or are unclear how to do this mod you shouldn't be doing it. You should be asking a friend that understands electronics better (aka major electronics geek) to do this for you.
Sorry I don't have pictures at this time.

Only the area where the GPS antenna resides needs to be shielded which on the Nexus S 4G happens to be circled in red.
Don't forget to protect the board from electrical shorts with scotch tape or the like.
Please don't put tape or aluminum foil over the spring terminals as they provide contact to the antennas on the back of the case.
The shield must be grounded for it to work, I used the metal casing inside the phone.
You can see where it comes close to the edge of the phone, it happens to be metal there and its grounded
In for pics. Also, which model phone.
crespo4g aka SPH-D720 aka Nexus S 4G
But TBH this solution should work on any phone that has bad GPS reception due to bad design and/or h/w interference.

Sounds similar to the other fix which didn't work for me. Do you have pics of your mod?

Yea I just put one up. I've tried many things myself but this has made my phone's GPS f***in fantastic and thought I'd share it with the rest of the world to enjoy. I first tried modifying my antenna with a wire after trying a bunch of useless s/w mods but still wouldn't work once reassembled and then it became obvious what must be done.
Dude, that fix looks so hood rich. I love it.

[TUT][DIY] Cheap External Antenna For HTC Sensation

Hi folks, several days ago I bought an 18cm high GSM antenna (really cheap, about $5 if I convert it to USD), and also bought a cheaper (if I convert it to USD it will be $0.66) SMA connector for it, and realized that the antenna connectors of the Sensation are on it's back cover, so I could simply connect the antenna to the phone.
well, first of all you'd better to watch W2AEW's awesome video about Decibels to actually understand what you're doin'.
here's the antenna I've bought (the seller told me it's 18cm high but it's 19.5cm :silly:

}
and this is the SMA connector, before you buy the connector, you have to find out if your antenna's connector is male or female. in my case it was male so I bought a female connector for it:
then you have to solder some wires to your antenna, one for the ground and another for the signal. coaxial cable is the best solution because of lower noise but it's so thick, here is some antenna wires I just found with a quick search on Ebay, and they're not that thick. also keep wires as short as possible, in my case I just wanted to test the antenna so didn't care about the wires:
the two connectors above the camera on the back of the phone are for WiFi, and the two below the SD Card are for GSM. so I connected the wires of antenna to the bottom ones, and, here's the result:
with the original antenna (which is the cover door of the phone):
without any antennas (without cover door):
with the external antenna:
I'm planning to drill a hole on a cheap cover door and mount the antenna on the cover, and also add some more antennas like GPS and WiFi. (then probably it won't fit in any pocket :silly: :laugh: )
if you tried it too, please hit the thanks button. :good:

All right, I'm waiting excited for the photo(s)
another thing I wonder is that if we can add an external antenna without loosing the 3G capability.
edit: I'm working on adding the antenna beside internal antenna so it will have both EDGE and HSDPA.
Thats really cool!
Will have a try this week :laugh:
It works and increases the db, but unfortunately it doesn't solve my problem, I wanted to keep in touch in a place which is far away from the operator antennas, but it doesn't help me because of the huge distance, maybe I should switch to another operator. so I discontinue this project but it doesn't mean that it doesn't work.

Sad to hear, that it doesn't really satisfy your situation and you discontinued the project. Can you please share a picture of the back cover anyway?
