I noticed a weird connector at the back of the device, I dont have a way to picture it at the moment but I found it on the internet.
Its under the cover in the red circle I draw,
Do any of you know what its good for?

I think it is for attaching a stylus.You just loop the thread through it and close the cover.
It's meant for a wristband. You can buy the accessory, loop it through that hole, and then close the back cover (so it never falls off).
Are you sure about it...?
I think you're wrong,
the wristband/small things you put on your phone like small dolls is the yellow square
this one is something different.
It its a connector for an external gsm antenna. However be warned, do not plug any thing in to it as others have reported this will disable the internal antenna and you will not get a signal afterwards without a visit to a service centre or some soldering.

I've seen that type of connector on other phone's in the past. I always thought it was for an external antenna. I'm not sure though.
Edit: mrm1 just beat me to it ^^^
That was my first impression, after seeing a similar connection for the wifi antenna in laptop's hardware..
Thanks, and of course, Im not planning to connect anything to it anyway
Hello , When I first Purchased my Evo 3D, I noticed that any usb cable attached to it would never fit snug it always had movement like wiggled alot. I should have exchanged it but didn;t think it would eventually lead to serious damage until now, well, somehow the first pin on the right broke off and checking online with research it apparently is the +5 of the usb. Which basically screwed me.
I don't have much of an issue with no longer having the usb data sync ability since I can just use a micro SD adapter, and I have an External Battery Charger from Radio shack which helps because I can just charge the batteries with that and insert in my evo3d But the issue I have now is I realize i rely on the 4G tethering ability which i use constantly and it has become a pain to have to run and switch over batteries so my wifi tethering can maintain my computers online.,
Anyway so noticed a few evo 4g mods online where the person would solder two wires one to the negative and other to the 5v positive where the usb is located and then shape the wires nicely and make a custom usb hole somewhere else on the phone and eventually have a usb charging ability similar to one of the attached pictures ( for evo 4g of course not for the 3d)
So anyway i would like to try something similar where i can just locate some solid solder points on the phone and wire up two 5v and ground wires and relocate a custom usb slot somewhere else on the phone, Below is also some zoom closeups of the evo 3d board so my question is any advice to where I can solder the 5v and ground to, I am clueless to where and what points i should try the underside of the usb slot is all metal so seems like not able to solder there maybe on one of the little chips or something perhaps
,, thanks for any help
in reference to the attached images:
the one with the 5v writing is for an Evo 4g Not 3d But Im putting this picture i found online just to give a similar idea of what i need to find on the 3d
the one with the wired shell mod us just Another photo online of what I want to do but once again need the solder points
the other two are the best closeup pictures I could find of the 3d which maybe someone can just point out to me the locations by looking at it, I will take clear zoomed in photos if needed when I have access to a camera at home
thanks anyone for your help!
Why don't you just take it to Sprint and have them repair it? They'll do it for free.
Not from I heard. They charge 100 to fix it. And not even sure they would give me a loaner phone in the meantime. Also , I went into RADIOSHACK and showed and.spoke to one of the reps and he.told me.I wouldhave to pay unless I had their extended warrantee.. I noticed a resistor like chip above.and in front of where the 5v pin is.I wonder if I can solder on that

Call sprint and talk to a supervisor. They will send you a new phone or set up repair for free. Call and hang up twice, then call again to get sent directly to a supervisor.
Unfortunately me being a tinkerer ended up breaking off the ground pin and was not able to get serviced , even tried the supervisor and no go, I tried another radioshack and sprint store and of course they noticed it was opened so screwed me out...
anyway,, I taken some fair quality images of the board surface. maybe a +5v location can be pointed out from the images? thanks again

Instead of making a new thread, I figured I would add to this... I too am trying to mod mine with inductive charging, unfortunately my hands are a little too shaky to solder to the point that I discovered to be continuous with the +5v on the usb port.
I can't really find a clear picture of the PCB anywhere otherwise I would show you, but its about a centimeter or two down from the top left when you open your phone, run your multimeter through those points and you'll find it.
I guess I came here looking for another point..

Hmm thanks. I will try it when I open the phone. The soldering point should be bigger than the micro-usb pin I would hope.
Hello xda I hope you can help me out.
I have just replaced my screen with a screen bezel off ebay. I managed to bend the plug on the top end of the white wire that runs up the Left hand side of the phone while trying to disconect it with a pair of plyers because its all I had.
I have put the phone back together and it seems to be working fine. I have wifi and microfhone works.
I am just wondering what that wire is for and if I need to get another one on order?
BTW the wire is not connected but the phone works fine as far as i can tell. I still have no signal, as it stuck on emergancy calls and has been for weeks due to no vodafone tower working in my town at the moment.

Hello
I have read that this is the antenna wire and it helps reception maybe even connection at all
I had the same problem with my old HTC ,the wire and the connectors in the galaxy s2 looks the same only its white
I bent the connectors and it couldn't fit anymore but i managed to bent them again with a needle and pliers so the wire could fit again, just take your time with it.
I have G9 80 16GB Turbo. The plastic part of the inner micro USB feeder is broken and sticked out to the USB charger pin. My USB charger cable now blocked by that thing and cannot be use anymore. Now in the USB feeder of Archos just remain 4 tiny metals without plastic support (only 4 USB metal pins connector) and not able to take charge by anyway, it is bricked because of no battery power.
It is just 2 months old and no warranty since I bought it in airport transit. 3 times emailed [email protected] with no response as the world has suspected.
1. I've checked my Archos and did not find any screw other than single screw in the USB 3G compartment. I really thankful if anyone can write step-by step dismantle procedure.
2. Can anyone share the shape of USB type soldered to the PCB to enable me order the part and soldering it alone.
3. I've search this on thread : http://forum.xda-developers.com/showthread.php?t=1557506, but the information provided on how to dismantle is not very clear.
4. Thankyou in advance.

There's only a single screw at the back.
The housing is hold together by some plastic clamps and it is a pain to open the case (at least compared to a A101IT Gen8).
You really need some force and be very careful not to damage anything...
I'll post a few pics this week in a different thread, because i opened the device last week and it was little bit catchy

Usually this is not an easy task... at least for the unexperienced ones.
Be careful with the thin lines on that PCB.
To unsolder the connector you'll need a lot of heat because it is connected to the gorund plane of the mainboard.
Anyway i don't know the manufacturer, but i guess these MicroUSB connectors are all pretty similar.
So try to catch one, wherever it is sold.

You should start on the opposite side of the connectors and use some plectrums (used by guitar players) to lift off the plastic clamps.
As i said i'll prepare some pics...
EDIT: Here's an overview on how i opened the case.
As already stated it was a pain, and though i had been very careful, some tiny plastics got damaged.
The red circles mark the plastic clamps and the holes they were stucked in respectively.
The green arrows mark the direction i slided my guitar plectrum.
In between you'll have to use something like a screwdriver or putty knife to lift the clamps from their counterparts (this was the evil part).
In the end lift the top of the housing in the yellow direction.
Please take care of the flat cables of the TFT display, don't rip it off!!!

scholbert,
I don't know how should I thanks for your detailed information and photo on your reply.
Below my comment:
1. There is no abuse on the USB port (even no single scratch or dent to prove the abuse, from new I feel it is really tight when I connect the cable into the port, finally the plastic part comes out "cleanly" along with the USB cable connector when I unplug. That's way I try to bet the warranty honor...ray.
2. I've checked eBay and I find many type of micro USB port selling.
3. Based on the generous help you've written I will try to dismantle my Archos when I have spare time within this week.
4. If I may ask, for what purpose you dismantle your Archos. And did you find any problem something like not properly tight when you remantle it again?.
5. From the picture, are all the clamps just on the display side, or mix up and down between the base and display?. Appreciate if you can post the zoom picture of the clamp and the hole to know it's anatomy to make easier when pushing during dismantle process. I also seeing 4 screw-like holes on 4 corner, are they also something like alignment clamps without actual screw?.
6. Big thankyou again for your response.

I don't know if i got a second edition device, but i realized this screen issue as well (pressure on the back causes effects on the display).
So i thought i may open it and try to solve this issue.
Anyway i always like to investigate on the construction of these devices...

To be exact, the clamps are located all on the base unit.
The display side got the holes for the clamps. I'll see if i could make a more detailed picture, to point you in the right direction.
Though i'm not sure if it helps.
The srew like holes you pointed at are for alignment only.
I also found some glue in the holes, but this is no problem.
Some words on seperation...
It worked out like this on the long side of the housing (upper and lower):
- I tried to seperate the display part and the base with the plectrum step by step
- tried to locate each clamp step by step
- then used a screwdriver
- tried to press gently against the clamp, direction outside to inside
(be very careful and the long side at the bottom, because of the display flex cable)
- then try to lift the parts more and more (it's terrible, but it works)
- keep an eye on the torsion of the display side
(seperate the parts too much, might crack the screen)
I guess i'll prepare some more pics...
Stay tuned!
scholbert
You are really a man god sent to me, thankyou so much. I'm really itching to do the job. First thing I will do once dismantle completed, is to wire two lines for temporary charging until the part I order arrive. If by any chance impossible to replace micro USB port, then I will make hole on the base for common round type DC charging port + and - only.
Hey cangguek,
as promised, here are some detailed views of the clamps (base unit) and holders (display side).
The are four holders in total with two holes each.
The holders are seperate parts and are mounted with three screws in the display part of the housing. Each holder fits into two clamps of the base unit.
Unfortunately they can only get disassembled after you managed to open the housing.
The edge of the clamps point to the border of the base unit housing.
So you may try to push them gently to the inside to release the mating part at the display side.
Anyway i hope things are clear enough now...
Some words on your idea of soldering a DC charging port:
Electrically this would work i guess, but there might be some driver issue which could prevent the unit from charging.
It depends on how the charger is identified by the software driver, which activates the charging process.
On some devices it is required to shorten the data lines of the usb connector, others use the id pin on the micro usb to detect wether a host pc or a wall charger is connected. I don't know how things are done on the Archos 80 G9.
I just wanted to point that out before you start soldering...
Good luck!!!

-Data lines are not shorted, charging cable is a fully functional usb cable
-There must be something done to 4th (unused) pin in micro sd plug so device can detect Archos/"normal" cables (my guess- check data lines->if usb host not present check 4th pin->original=fast charge/3rd party=slow charge)

Yeah i know that the data lines in the cable are not shorted.
AFAIK, they get shorted when connected to the wall charger.
I own a Milestone phone (which definitely requires the lines shorted for charging) and i successfully used the Archos wall charger to charge this device.
At least i wanted to point in this direction...
Thanks for your comment.

Dear scholbert,
All the process as you said really a devil. I am stuck here (at red arrow) and can not proceed unless I tear it with force. Seems there different clamps ?.
Now I am stopping the the job waiting your further help.

Yeah i know it hurts... but AFAIK all the clamps are identical.
Nevertheless i realized the same during disassembly.
Some of the clamps did release quite well, at some point i also was afraid i'll break the device into pieces. I'm sorry but i guess you'll have to use gentle force to get it seperated.
BTW, i don't want to be responsible if you damage something
Another warning at this point:
I even did break some small plastics during opening (in the mainboard area), but it doesn't matter in the end, because there are many clamps to hold the parts in place
Good luck!

Anyone would come with idea on how to trick my situation?. Removing external card-slot then removing micro USB port seems a big job to me. The solder were very-very tiny...
I have completely separated and disconnect the wires of my Archos, so I have two part now: the base and the display part.

I am happy to see these pictures as they confirm my suspicion. The usb charge port is only soldered on, no screws to hold it in place. That is not a proper mechanical construction and it is no winder it becomes disconnected with only a little use. I have sent 2 units back already which will no longer charge as the mount point has come loose. Number 3 broke too now and as they want me to pay for shipment again ( €50) I am thinking of fixing it myself in stead, but properly..
I have the same problem
Did you eventually repair this problem. If so were did you get the spare part. i have got the same problem. I think i might try returning to my supplier first.

I was thinking about getting a magnetic cable because I want to spare usb seal from wearing out. I noticed that some of the people are having problems with it and they managed to brick their phones by plugging the cable in wrong direction. I checked few of cables available in stores and I noticed that they are not marked in any way and there's no information about "how to plug it in". I'm wondering if there's some kind of rule how to plug them in. Is anyone using them instead of Sony dock?

I'm using it for some months now, and I can say that if you're using the original Sony cable, you're pretty safe.
If you look at your mobile carefully you'll see that the magnetic frame for the connector has two pins with different geometric forms. Those pins fit exactly on the holes on the cable, in only one direction. You'd have apply a big force to make a mistake.
Besides this, the cable "head" is not symmetrical: one side has a wire, another doesn't. So if you plug the connector with the wire aligned with the "foot" of your mobile three or four times, I think you'll find it too strange to plug it with the wire aligned to the "top" of your mobile.
The experience with the Sony cable is great, and I don't have enough good words to recommend it.
I haven't noticed that connector pins are not symmetrical, thanks for pointing that out. This will definitely help. I'm wondering how people managed to brick their phones by plugging it in wrong direction, if you need to apply some of the force to plug it that way.
I'm thinking about cable because dock costs a lot, considering that I'd use it only for charging anyway. What's the code for magnetic cable from Sony? I might try go grab these here.
I plugged it upside down once. It rebooted the phone. That was it. Nothing bad happened.
