Loose Mini-USB Port? - 8125, K-JAM, P4300, MDA Vario Accessories

On my XDA Mini S it is loose. Does it simply have to be soldered back on?
Thanks

depends on what is loose: the four legs that hold the port to the PCB or the 5pins that are responsible for the communication lines (and charging)

But if its any of those, is it still repairable?

Yes it is. In fact there is a dedicated thread to this issue where i gave some tips.
i've managed to recover one wizard that had the port complete removed after a fall. The four legs were easy but the big problem was the other five contacts since they're really small and are hidden underneath the port. Long story short i had bypass the circuit by soldering a couple of copper wires directly from the port contacts to the resistors in the PCB

read my thread posted in my siggy...it gives great tips.

[Q] Anther x10i Charging Problem !!!!!!

I know this isn't a new topic and I've read lot's of posts about similar problems, with various causes and fixes, but my x10i isn't charging at all. Neither through the wall charger or through the usb. When I look into the charging port I can see that one of the little metal pins is bent right up, so I've decided to try and replace the charging block.
I got a charging block off ebay, but I'm no expert when it comes to soldering & electronics, but since the phone is dead anyway I have nothing to loose.
As far as I can tell when I look at the original one, there doesn't seem to be any signs of soldering in the first place, although the connections are all so tiny that it's hard to tell.
So am I right in thinking that the charging block doesn't need to be soldered at all, and could I get away with just gluing it to the board, and if so what would be a suitable glue for this kind of purpose.
Thanks ...John...

i have the same problem with my x10 but i have warranty but whilst i was waiting for them to collect it, i cut my usb lead up and stripped the black and red cables back obviously positive and negative and took the battery out and wedged each cable on the phone connector with the battery my battery had a plus and negative signs on it so was easy 2 work out, it charges the battery but it doesnt come up as charging on the phone it will still blind red lights but doesnt turn off, you have to keep and eye on the charging levels on the phone status do not let it go over 99% as this method dont tell the battery to stop charging, also this is not full proof and could break your x10 if not dont correctly,but as for your question the usb port does need to be soldered good luck

Hi John,
I fixed my friends USB port, you will need:
"helping hands" (a tool for holding small things with a magnifying glass)
0.5mm or 1mm Soldering iron
Hot glue
Under the magnifying glass, there you will see the 5 pins the usb port was solderded onto. You will need to put a little bit of solder onto each pin and onto the board.
Hold everything together with the helping hands, and just tick the soldering blobs with your iron. This will connect all the points. Do not solder for to long, or you will bridge pins or remove the solder.
Continue until all 5 is connected. Solder the 2 points on the side (holds the USB port, you could do this first if you don't have the helping hands)
plug in cable, use multimeter to see if there is current by you battery pins.
Voila.
If no power then you have to follow one of those fixes online where you have to bridge the doide and the V+ port.
Thanks for the info, like I said the phone is dead anyway, so I can't really make it any worse (That's what I keep telling myself anyway).
It the parts were a lot bigger, I probably wouldn't be bothered as much, but if I do get it wrong, I'm hoping I can take it off, remove the solder and just start again. (hopefully)
I think I have a good idea now of what I'm supposed to be doing, but I'll probably have to wait till I get a new soldering iron, as mine is a little bit too big.
Thanks ...John...

Atrix Inductive Charger?

Just wondering has anyone tried/thought about the feasibility of modding a Palm Pre touchstone charger for use in an atrix? would it be extremely difficult to do so?

xboxexpert posted a tutorial for this on a nook color here . Looks easy enough and the same method should apply.
Hmmm.. interesting.. only wished someone would have tried previously to know if it'd fit inside the battery cover...
After looking at the iFixIt teardown for the Atrix I'm not thinking this would be a straight forward process.
http://www.ifixit.com/Teardown/Motorola-Atrix-4G-Teardown/4964/2
Boards aren't my strong point but it looks as though the +/- may be under the usb connector housing.

Need a better shot, but it looks like you can still hit the resistor between the two ground posts. Going to need some thin wire though.
I am curious to know if anyone will attempt this.

Don't think I'm going to sacrifice my Atrix to the hardware mod gods. Enjoying it too much and not terribly interested in dropping the money to replace it if it doesn't work out.
I don't know if I will be doing the mod, but these are some of the tips I would follow if i decided to. If I do it I'll post pictures..
1st:
Be sure to use the Palm Pixi's back cover with the smaller circuit board - this one.
Click to expand...
Click to collapse
2nd:
You might wanna consider buying this case since its thicker and you can dig a little bit if the circuit doesn't fit the standard battery door.
Click to expand...
Click to collapse
3rd:
In many phones the metal that keeps the memory card in place is the ground (-).
Click to expand...
Click to collapse
4th:
I'm sure there's an easy (+) pin you can solder to - so far i haven't found one, but many people cut a usb plug to fit inside the usb female socket and route the cables somehow (Watch the first video below). You have to remove the cut usb in order to use it with computer, also its quite ugly. The best, but very hard way is to solder the (+) wire directly to where the usb socket is soldered to the phone's circuit board .This I'll leave to a jewelry craftsman, I know, with lots of experience. MAKE SHURE YOU KNOW WHICH PIN IS THE POSITIVE!!! For polarity of the palm pixi's circuit boat refer to the first picture.

I know its a bit difficult, but... that's the way it is.
Useful links:
Galaxy S Mod.
First HD2 Mod.
Same mod but with extended battery (Not good looking)
You have probably seen this.
A lot of people forget to do this.
YOU ARE WELCOME!!!
I bought some of the pixi components and will try this out without the requirement of soldering.. I've been thinking.. is there any way to use the leads from the battery as the connection point as opposed to soldering directly to the port? Or is there a voltage regulator that I'd have to go through first...
First, you should try if it's really charging Atrix (batt's percentage going up), because it needs more current than standart phone.
But i'm thinking of modyfing my own, but with less invasive method
I wouldn't take apart my atrix again. I may have killed my first one getting my screen out. Those ribbon cables are a pain, and well, you might not need to remove the flex cables (the black flat ones), but if you do, you are most times pulling up the temp sensor too, and that thing never goes back!!
Just make sure you are good at what you do
Why not solder the the inductive piece to a chunk of mini usb cable first ? Completely non invasive and you'll be able to prove it works before you solder to the phone.
That was what I was considering. Unfortunate that the variances for the attrix are so tight.

If you're going to do that, you may as well just buy one that's already made.
I meant to do that as proof of concept. If it charger, take it apart and hide it under the battery cover.
Does anyone tried the Palm inductive charger with Atrix? Does it really work?
I just got mine in - will try it soon.
Let me ask you guys this...
1) Whats the point of all this?
Really? What is the point? The cool form factor? Bragging rights? It seems like
a big inconvenience for me, especially when you will need to take your charger somewhere.
Anyways, seems like a lot of work for just the convenience of not plugging in a mini usb cable.
Anyways, good luck and I hope you guys have fun
Perhaps you are right about it.
But whats the point in buying a lapdock or media dock when you can just get a laptop? What's the point in rooting or unlocking your phone? You could easily just leave it stock and most of the functions will work just fine.
Call it a hobby or challenge or a convenience or whatever. I made this thread merely asking for technical help. Not snide commentary that is counter productive.

First, check for disconnected or loose cables inside the gTab.
Next, if it isn't a HW fault like loose cables, then connect the USB cable to the gTab and run this ADB command (you will have to install and set up ADB if you haven't already done so):
Code:
C:\SOME\PATH> [B]adb shell "echo -n 1 > /sys/devices/platform/tegra_touch/calibration"[/B]

I assume since you didn't send in under warranty for the power connector that it's no longer under warrantly!
Exactly where is the break? Close to (or at) one of the connectors? Which end (motherboard end or digitizer end) of the cable? Obviously closness to the connector makes it more difficult. I have seen a post where another use had the break pretty close to the connector & fixed it though.

If you magnify the digitizer circuit (lower photo in the pdf) you will see the label for each of the lines in the cable. Assuming the lines run straight thru, it looks like the ones that broke are the power & ground to the circuit (VSS & GND). That would explain the touch screen not working at all.
Hard to tell from the video where the breakis, but it looks real close to the connector.
Your best bet may be looking for someone who has a broken digitizer (outer glass) or gTab and is selling it for parts. I looked in the Marketplace forum here on XDA & there is one non working gtablet someone is asking $55 for. I also saw another one up for bid on ebay ($40 latest bid). You my have to ask if the cable is good on them.
Not a whole lot of options for repair. As you've already experienced, the cable is small & fragile.
If the connector has removable pins then you could remove the pins, solder the wire to it & reinsert the pins, BUT from the picture it doesn't look like they are removeable.
You could solder the 2 wires to the pins coming out the back of the socket but they look too small to easily solder to.
The last option would be to rigg the cable to work. There are a couple of possibilites but I would rather you consider the other options before suggesting a repair of the cable itself. If you can, see if you can take a closeup, high res photo of the back fo the connector where the wire broke. PM me & I'll send you my email address to send it too.

[Q] Need help on how to dismantle Archos G9 80 16GB

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!!!

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...

-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.

Ok
-data lines are shorted together in charger (not to gnd/vcc)
-that's strange but 4th pin seems not to be connected anywhere
sorry, left empty.
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.
Thankyou for helping me:

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!

Just to confirm the only screw I removed only the one under the stand stick, I hope I am not missing here. I am still not continuing dismantle process, but at least 40% of the casing has been opened.

Man..., wtf, bottom pin of micro-usb (for desoldering purpose) covered with external card slot...grrrrr,....
Please look at the usb pin inside the housing, only metal pins only remain, the plastic part were come-off sticked-out along with usb charger cable. 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.
Anyone asking specific picture parts of my Archos, I am ready to shoot.

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.
Brilliant tips

Uuups this is bad...
It's sad that they did not reply, but do you think it is covered by warranty if your borked the USB connector?
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!!!
You're welcome!

Great tips & will add my own step by step as replacing my screen on G9 after it parachuted from 2 foot onto a rubber floor!!:good:

I'd be very interested in this and to learn where you bought the replacement screen...
I have an 80G9 with cracked screen and LCD and busted digitiser.

[Q] Captivate usb-mainboard problem

I have a captivate with bad usb port it was charging but can't get connected to the computer I opened it up and found out that there is a problem with the board the place where the usb port should be soldered (the pads) is gone.
I'm asking is there a way to put a wire connecting to some place on the board (the place where it should go)????
plzzzzz help me guys !!!!
Wow, that's fried.
I'm amazed that it even charges.
I think that I'd unsolder the connector and scrape all the burnt junk off, glue a new connector on the surface, then run wires to where they should go.
The D+ and D- should be somewhat easy to track down.
Those data lines usually run close together and they go to two "build-out" resistors before they go on to some chip.

I tried to track it down but I couldn't so I'm asking if there's any map or a scheme for the mainboard to help me!!!
