Working Motorola Dev Cable - Atrix 4G Android Development

I'll make sure to get some photos up soon of the whole operation.
Anyway I managed to get a Dev Cable built to successfully re-flash firmware to the Atrix. I actually bricked my phone three times and instantly was able to re-flash to 1.8.3 and higher.
So first off I found a previous post on another form about making a dev cable and noticed all you need to do is run a wire from the 1 pin (which is 5V) to the 4 pin (which has nothing attached to it).
Micro USB pin diagram here:
http://www.kineteka.com/microusb-b.aspx
It seemed simple enough, but in reality it is a slight pain to get inside the injected plastic to get to the pins. Basically what I ended up doing (and I'll get pictures up here soon) is cut into the USB cable about 2 inches behind the micro USB plug to make the red wire (5V) accessible. Next I cut off the plastic shielding around the micro USB and slowly pried away the metal clips. The important part here is to not break off the tip of the USB cable that is used to secure the cable to the phone.
Now the hard part… if the plastic is clear then your work is cut out for you and you can just melt the plastic to the 4 pin connector and solder. If it’s not, then you have to do some careful exploring, the best option I have found is to melt the plastic to find the 4 pin. Cutting away the plastic also helps but caution you might cut into the wrong area and sever a wire (I did this twice already). Next step is to clean and solder a wire to the 4 pin connector; I used the wire from a butchered USB cable from this project, make sure the wire is long enough to allow for errors.
Finally run the wire back to the first cut in the USB cable and solder or use heat shrink tubing to bind the Red Wire (5V) to the jumper wire that runs from the 4 pin connector on the micro usb.
With a little luck it should work!
My soldering is not that great and one out of the two cables I made worked.
If you have any questions, ask!

Buying one would be the perfect from you or ebay. I can't believe you bricked your phone that many times.

Is this not the same thing people were doing months ago to get USB host support? I made your same "dev" cable using an OTG cable and doing the soldering you did to the pins on your cable instead to the inside of a cheap USB hub. This made wire stripping and melting altogether unnecessary.

Sure I don't see how it couldn't be used like that. I just did this because I had a few extra micro USB cables laying around and one bricked phone. Mostly I wanted to see if this would work... I did notice just now (at the time I just wanted to show the diagram) that the link I posted to the USB diagram actually just has the micro USB connector as a part. Which in all reality is somewhat easier since all you need is the 4 wires from a cut USB cable and a jumper wire from pin 1 to pin 4 and then shrink tube from there.
But I worked with what I had at the time and it functions.

I didn't mention hard bricking, just bricking in general. I have another phone that has the
Code:
0x1000
Entering NVFlash recovery mode
Battery is too low to flash
that shows for three seconds and then the screen goes blank. From what I understand that is more of a hardbrick.
I'll try it on that and see if I have success.

cool work mahn!!

You have the numbers reversed anything that says failed to boot x1000 is a hard brick and apparently motorola doesn't fix them they usually give a refurbished phone.

Agree the I pulled out the phone that had a backwards firmware flash to 1.8.3 (the failed to boot 0x1000 one) and so far no luck on being able to get the NVFlash to stay up longer than a few seconds. I'll look into a few more options maybe I'll find out how to do this JTAG fix rumor that I see floating around on these forums. I know it's chasing ghosts through concrete walls, but I have the time/hardware to do it.

Do keep the updates coming if it works for you.

[HARDWARE] Dinc Seamless Wireless Charger stock battery (NO USB STICKING OUT)

>>>>>><<<<<< PDF With All Steps And Images Added For Your Viewing/Downloading Pleasure >>>>>><<<<<<
***If this does not belong here I appologize, and feel free to move this if necessary. I just figured the development community is most likely to take this "upgrade" on***
After seeing that someone used Palm's wireless charger on their non-palm phone; I decided to put one on my Droid Incredible.
***This was done to a completely stock Dinc. I did not use any special back, and the stock back gets to stay on (unlike in the other video that I saw)
Wireless Charging the Droid Incredible
**Disclaimer: This will void your warranty, and if you solder something wrong will probably break your phone. With that said I can in no way be held accountable for anything that occurs while performing this “upgrade” to your phone.
>>>>If anyone knows where I can buy that little void sticker that you will see in a picture below, please let me know! If we can get that sticker then our warranty is not voided by doing this.
Supplies:
1.Palm touchstone charger http://www.shopping.hp.com/product/handheld/categories/palm/4/accessories/FB300AA%23AC3
2.Palm touchstone phone back http://www.shopping.hp.com/store/product/product_detail/FB306AA%23AC3?
3.Micro USB cable
4.Soldering Iron (the finer the tip on this the better)
5.Torx T6 screw driver
6.Safe pry tool (or a small flat head screwdriver)
7.Very tiny insulated wires (I just pulled mine out of a USB cable that I cut up)
8.Electrical Tape
9.[Optional] Multimeter to test that you actually made a good connection
How To (Images are of a higher quality (12mp) so I had to stick them in zip files to get them on here):
1.The palm touchstone phone back has a sticker inside of it that encases the wireless charging receiver, so you need to peel this off. Once it is peeled off it will look like this (without the wires soldered onto it):
(Images can be seen in: Palm Receiver.7z)
2.Remove the battery cover and the battery then unscrew the back from your phone (please view a tare down video for details, there are plenty of them on you tube that I used for a reference.)
1.All you need is a torx t6 screwdriver and a safe pry tool, I used a small flat head screwdriver and it worked just fine. Unscrew the 4 screws around the sides and then carefully pry off every place that the battery cover clips on, as they also hold on the red back.
(Images can be seen in: Dinc Inside.7z)
3.Solder on some wires to the USB connector as shown in the below image without soldering onto the pins next to them. This is difficult and takes some time and patience, since these connectors are very small and close (note the polarity in the image, notated in red).
A.Also it is necessary to place a piece of electrical tape over the components right next to the connector (Green box in the image) as they will short out the power and make it impossible to charge your phone if you do not (I found that out the hard way and went back and fixed it).
B.One final note here is that I had to melt down the red phone backing inside to allow the cables to get past the case. See the green rectangle in the image above for where I had to do that. I just used my soldering iron and melted it down, it makes a pretty nice indention for the wires to fit through.
(Images can be seen in: Dinc USB.7z)
4.Now push out the rubber plug in the red phone backing next to the USB cover (this is encircled in Green in the image from step 2).
A.Run the cables that you just solder on through that so that they are sticking through to the battery compartment on your phone.
B.You can also stick on the palm receiver to the inside of your phone cover (note the direction and placement, as this is necessary to close your cover).
3.Note that I placed electrical tape over the wires. This was necessary to keep them from breaking off of the USB connector since the solder points are so small.
(Images can be seen in: Almost Done.7z)
5.Solder on the wires to the palm charger receiver and you are done. Now you just need to carefully place the wires towards the middle of the phone so that you can close the back of your phone entirely (this is another reason why the wires need to be small).
A.Note the polarity of the connection.
B.Also I put a piece of electrical tape over the connections on the palm charger receiver to protect them (not shown in the image).
(Images can be seen in: Wireless Charger.7z)
Here is a video of the end product and how it works:

Also I just verified that my compass is working without any problems.
This could be truly amazing. I can't wait to see more.

Its been done with the Evo, but don't know anyone who did it with the Inc.
http://www.goodandevo.net/2010/06/h...rk-with-palm-touchstone-wireless-charger.html
Sounds really nice. Not gonna try it with mine because I'm too scared
Though shouldn't this be in accessories or general?
What are you doing to align the coils? My biggest concern that's kept me from this is the magnets also would mess up the compass sensors readings which I for one actually value.
Wow, you managed to bring me out of my months of silence in posting...
I feel honored that I can get you out of your months of silence
The coil alignment is handled by the magnets inside of the palm touchstone charger itself (the base unit that plugs into the wall). The metal objects that you can see in the "Palm Receiver.7z" file are actually not magnets, but small circular pieces of metal that get pulled towards the charger base when you get them close to each other. So when you have the phone off of the charger, there are no magnets to mess with anything
Also you will notice that there is a piece of metal behind the coil, and that seems to block the inductive signal all together (because I tried to put it on backwards to no avail). Therefore your phone is mostly protected from the inductive transmission.
The only thing that I noticed, is that the touchscreen on the phone is a little weird when it is on the charger, but I see the same side effects when plugging the phone into a "non-htc" charger (before performing this "upgrade"). **I also saw this on my Moto Droid when connecting it to a 1 amp charger, and I have seen this with multiple other touchscreen devices so I think it just has something to do with the frequency of the charger.
Also in case of any concerns: MY PHONE HAS IN NO WAY BEEN DAMAGED BY THIS "UPGRADE"

Yah, it probably should be, and may get moved (which is perfectly fine by me). I put it in here because I am a developer and much more likely to do this, so I figured the development community would be more interested.

I have a rubber case on my Dinc... would I need to remove it for charging?
___________________________________
Yup.... The ones yoe momma told ya about.... Bad Seed Customs!!
I think you will be ok if it is one of those thin (about 1mm thick) rubber cases. Anything thicker than that and you would probably have to install the wireless receiver on the case itself and remove your battery cover all together.
I tested a thin rubber case that I have (no more than 1mm thick I think) that fits a Droid Eris and it charges as long as its flush to the back of my phone.

Wow, this is amazing, very well done. I think this is the first hard mod I've heard of for an Android. I guess gold cards were a sorta gray area.
I've had my Incredible modded to work with a Touchstone since around June of last year. It works great, but I must caution anyone thinking of doing this to be VERY careful. Experience with soldering and a steady hand is a must. One could fairly easily mess up their phone attempting to do this.
Could you do this with a powermat if you wanted to? I have a few laying around I could use.

No, the transmission of data wirelessly is achieved through modulated EM waves. This is simple inductance: a changing electric field creates a magnetic field, a changing magnetic field generates an electric field, so a current carrying loop placed near another loop of wire will induce current in the other loop. The receiver in the phone is engineered to "create" the "proper" amount current to charge your battery when combined with the base. In theory yes, but not with this equipment.
How does the phone treat a USB cable being plugged in - will it charge ok, and have your data transfer rates been adversely effected? I wouldn't think so, since you're only touching the power...

I have used the USB charger and data transfer cables without any problems at all. Also I have copied some files off of my phone to my PC since the "upgrade" and did not notice any extended times or anything that would remotely make me think something was wrong.
I did not run a speed test before and after to see if anything slowed down, but as you said we are only touching the power pins, so I highly doubt anything has changed.

Fix Broken microUSB Port

So the microUSB port on my Captivate stopped working the other day (can't connect to pc or charge without applying significant pressure in a certain direction) and I'm thinking about fixing it my self.
I'm really just looking for some advice from people who have done this before. What kind of soldering gun should I get (or will the Radio Shack special work)? What kind of soldier should I use? And should I think about buying a new micoUSB port from one of these parts stores?
Thanks in advance!
I wouldn't fix it myself...there is more to it then you think

I'd stay away from radioshack soldering irons. I bought a cheap $30 Weller iron and it is way better. The repair is not horribly hard. The worst part is removing the bad one without lifting a pad. I lifted a pad on one I tried fixing and screwed up one of the pads and a tiny bit of the trace. Needless to say I could not fix the tiny damaged trace and sold it off for parts. But the new usb went on without a hitch with some good solder and some desoldering braid.
I offer this repair as a service and for way cheaper than ruining your board...

It's virtually NEVER the connection between the leg and pad that is the issue, but rather always the inner connector that touches with the pins on the USB cable itself. So basically no, re-flowing the legs to pads won't do anything. I always ohm through the leg to the pad before replacing them to check if it's an easy fix but that's never the case and the whole connector ends up being replaced...
Download Jig Works But Won't Charge/Connect USB
I think I am having the same problem. I can use a download jig that I got from MobleTech some time ago, but the USB will only connect if I fiddle with the connection and will drop out almost immediately. I first noticed it because the phone was not charging overnight. I was running teamhacksburg ICS and thought I had developed the charge bug, but appears that I might need a new USB connection. Have tried differn't computers with same results. Is it safe to say I need a new USB port for my Captivate or are there some other things I should check. Thanks for the help.
If it's finicky like that then yes almost certainly.
So how would you go about replacing your USB port on your Captivate? or is it not worth trying for most people? One of the pins on my port came loose and got smashed to the outside shell. In trying to bend it back, it broke of course. So now no Download mode from Jig and no computer recognition.

I never got a PM but I followed the clues over to mobiletechvidoes. Once you add usb repair to your cart and check out you will receive an email about sending in the phone (after an hour or so) and I have just sent one in. It says send the phone without a battery or battery cover and I went ahead and wiped the phone just for safety.
Anyone ever find the link or know how much this costs?
in my sig if i remember correctly it is about $35
I paid $35 and it worked out well for me! Mobiletechvideos.com is where I signed up and they were fast and professional.
Fixed with vice grips
Just did this and slowly applied a little pressure and adjusted for more pressure at the end of the USB metal connection. It's a sturdy fit now and I'm not losing connectivity.
So the fix is to replace the connector altogether? Does anyone have a digikey part # or equivalent?
My issue seems to be that it charges, but I have no data connection. The pins don't need a reflow. Unfortunately, I don't have a spare micro usb cable to splice and check continuity on hand.
Is there any way I can talk with the enumerator chip to make sure it isn't fried, or should I just do the continuity check?
hi
I have the same problem, i searched on sites how to change it your self, but i couldn't find anything

MICRO USB
Anyone else had the USB port become mildly loose (moves back and forth if any pressure is put on the cable)? I believe its on its way out.

[GUIDE] DIY smallest Micro USB OTG to USB Adapter

Update: v.2! (half a penny)
Inspired by this video/OTG, pass to 0:47. Which I couldn't find one to purchase. This L design when plugged in is a bit smaller than a penny. No welding needed! Use (female USB for game controllers, mouse, ect). Designed with a case-on in mind.
======
You'll need 3 parts for hardware. Micro USB OTG, Micro SD reader, ofcourse Micro SD card and a software of your choice to run it. I don't root so I'm using Nexus Media Importer.
Be safe and wear gloves. You don't want to get hurt for this mod.
======
Step1: Cut in the middle of the left or right side of Micro USB OTG. Be careful, use glove on the hand to hold it down. (note: the OTG link that i provided is the exact one that I used to mod, but you can find the cheapest parts from Amazon or Ebay, ect.).
Step2: Peel out the inner part of the OTG.
Step3: Cut the part closer to the Micro USB completely off (with wires still intact). Carefully peel the wires to the far end of the USB female. Then cut the rest of the plastic off like in the picture.
Step4: Turn the Micro USB end to make a L shape like in the picture. I used glue gun to clued it together. You can use electrical tape if you like. Enjoy!
**I'm not holding reliable for any injuries or broken parts from this mod, do it at your own risk**
This is the original size of the device when it's plugged in, it's about 3 size of a penny in length.
Step1-3
aaaa
Step4
====================================================================================
Version 2 still retained female USB for mouse and game controller or a case in mind.
==========
You'll required soldering, glue gun or electrical tape. (note: this version is a challenge to make. If you think you can solder the wires into the small spaces on micro USB's bins then proceed or you can make version 1 which required no soldering)
==========
Step1: Strip micro USB and female USB completely. (any spare female USB from old devices will do. Make sure you have the right micro USB end like in the diagram if you decided to get a spare)
Step2: Measure the wires as needed from micro USB to female USB. Then pre-cut the outer layer of the wires so you can bend at 90 degree angle with ease when wiring the wire along the sides. (careful don't cut the wires inside). Next, strip a few millimeter from both ends of the 4 wires.
Step3: I suggest to lay the 4 wires on top; along the micro USB and solder it in the pins. (though I didn't realized this obstruction was a big deal until it resulted in a bump on my model when wiring it downward). Curve your stripped end of the wires for easy soldering. A trick I used to solder the wires to micro USB is putting a thin foil paper in between 2 pins. After you're done, remove it and repeat until you're done.
Step4: Lay your micro USB on top of the solder point of the female USB at 90 degree to shape the L. (make sure no metal part of the micro USB touches the female USB sholdering point. You can lay it on top of the female USB but it will add a few millimeter thickness). Follow the diagram to solder all wires to the female USB.
Step3
aaaa
v.2 when plugged in it's half a size of a penny. You're seeing USB plugged into the OTG with microSD inside.
**Credit to redgreenlaser for diagrams**
Thanks for the "how-to", Capt.PP.
Thank you, with your suggestion, and pictures, I can also put the USB behind the tablet as a U, and maybe make it smaller without the USB (male and female) only the card reader
I like it!
It's quite similer to the one I made:

Cool, Aleemz, how did you make yours?
If you want to make it smaller and you are going to the trouble of handsoldering and hot glueing, you can just get the Micro USB Plug
http://www.digikey.com/scripts/dksearch/dksus.dll?vendor=0&keywords=609-4051
Remove the USB shield, solder the Plug Directly to the USB traces, and Hot glue around it, you can reduce the size by half (maybe even more)

Nice one.
I'd rather use a USB flash drive but I've contributed nonetheless.
DIY smallest Micro USB OTG to USB Adapter

I think that, if I were to make one of these, I would make it in a "T" shape after removing the male and female USB connection, with the opening for the micro sd card facing in whatever direction seems best, so long as the card and its holder are parralel to the side of the device that the micro USB port is on. That way the whole thing would stick out no more than 5/16th's to 3/8th's of an inch when plugged in to the micro USB port and the protruding top cross part of the "T", that being the part with the micro sd card, would act as a grip for removing the device from the port.
(If that makes sense.)

You also have to look at cost effective here. The parts that was used only cost $1 for OTG, 30 cents for small USB, minus the Micro SD card. Though i'm not recommending 30 cents for small USB (they didn't clued it and harder to get the Micro SD card out) compared to the one above I recommend in the link.
The L design flushed with the screen surface and thinner compared to the bottom surface or a device as a whole. It prevented from accidentally snag the OTG when swyping on the screen. It's very easy to plug or unplug since you have a penny side in width (when you DIY you can add grips) and 2 penny side in length if you have a big thumb.
The T design, if i understand you correctly, you want to stick out above the screen a bit so you have grips to pull it out? I can ensure you the L shape have no problem of unplugging. Though you eliminated the female/male USB but it still lay hidden on the edge bottom of your device. Instead of buying new parts (may cost more) you can use the OTG I recommended to strip out all the white plastic to make it even smaller as you want to reduce in length when laying on the edge bottom. Cheer.

It's quite similer to the one I made:

Where did you get your inspiration. Great minds think alike.
Cool I'll tried one
I am going to just try soldering/wiring a micro-usb jack directly to a 32GB flash chip from a torn apart flash drive. Still waiting for parts to come in the mail. Here is a pretty good wiring guide that should help anyone looking to do the same.

You could probably do the same thing with a micro-sd hard adapter.
Also another idea : Build it directly into a case, much like this Galaxy Nexus Battery Case

Hey, I'm not very electronically inclined. Could I pay someone to make and ship me one of those "plug" OTGs? I have a 3" cable one, but I LOVE that little plug.
I'd even order one from Hong Kong and wait for it
Thanks
This one looks pretty good, for those who want it as un-obstructive as possible. I ordered one but will have to wait for it to see if it works fine.

Oh snap, they read my mind. I finished v.2 of Micro USB OTG to USB Adapter but very similar to this last week, but since I sold my phone I couldn't take pictures and post DIY v.2. From the look of this, it seem my v.2 is even smaller.

[Q] Replace USB Port / board

The male pins on the bottom on my Touchpad are broken (fell while it had a charging cable in it and of course landed right on the cable/port)
I can charge with a Touchstone charger just fine, but I want to use things like AcmeInstaller v3 and AcmeUninstaller, so I have a few questions:
1) I've looked at videos of how to take it apart (it's not under warranty anymore). Does anyone have experience with this and can relate to me how hard it actually is?
2) Does anyone have or know where I can find the USB port/daughter board that goes inside? I know it can be replaced, and I can find broken Touchpads on eBay but thought I would ask here first.
3) Is there a way to use Acmeuninstaller and AcmeInstaller v3 without being plugged into the computer via USB? (I'm figuring the answer is 'no' but figured it can't hurt to ask)
Thanks in advance for any help!
Re question 1 replacing USB board , there is a step by step guide with photographs in the iFixit app available in play store or from there website.
Thanks sstar! Found the guide here, now just have to find the part or a broken Touchpad on the cheap
Yeah, its super easy to remove. Parts, not so easy to find...

Opening it is easy but still terrible. The clips are horrible, I ended up breaking nearly all of mine.
That's what I'm worried about. Any tips? How do you keep yours together now?

Omg... just looked at that link for how to do it, and that's terrible. Lol. I use butter knifes and can still do a more sensible job of it. You can release the clips even before you pry up.

[Q] Charging cable using metal pin not microusb like dock?

Yes.
Edit: Sorry, that is totally wrong, and intentionally brief and useless because I thought I was posting in Nexus 10 thread and that you just hadn't bothered searching (for pogo cable). My bad
Anyway, now we're on the same page, there aren't any cables that I'm aware of, there has been talk of DIYing one but so far the best is some sort of dock or click on connection to the pins as per the thread linked below.

A quick google search said no.
I guess you could make one by yourself. I've been thinking about this too...
Step1: find out the polarisation of the connectors on the phone
Step2: take a straight piece of plastic, make two holes with the right distance to eachother (pro version: make 4 holes)
Step3: put some wire through it and bend at the end to make a connector (put trough other holes of you made them)
Step4: solder a old usb charging cable to the connector
Step5: use rubber bands to hold in place while charging. take care it is the right way round because of the polarization. (and the polarization issue is why there are no official cables, stupid people would all connect it the wrong way round and then be pissed "Y IT NO WORK??!!11")
alternative: you can use the small crevice between body ad display to hold som kind of clip in place, instead of the rubber bands...
