[FIX] Unbrick captivate w/o cutting up USB! - Captivate General

I have discovered a cheaper and less destructive way to unbrick the totally bricked captivate using only 3 resistors, THAT IS IT! No need to cut up your USB cord, JUST 3 resistors.
Below are the steps and pics:
YOUTUBE INSTRUCTIONAL VIDEO
1. Go to your local Radio Shack and purchase a pack of 100k ohm resistors, the colors should read Brown/Black/yellow/gold (see pic 1)
2. Take 2 of the resistors and twist them together
3. Take the third resistor and twist it onto the other 2 to make a straight line of 3 resistors
4. Bend the 3 resistors into a teardrop shape (see pic 2)
5. Set down a piece of tape and place the tips as close together as possible without touching while leaving about a quarter inch of each tip exposed, this will take some patience and adjusting (see pic 3) *tip: try putting a piece of tape or two in between the tips so that they do not touch each other*
6. Once the tips are set correctly tape both sides of the tear drop so no metal is left exposed. If your skin touches the metal it reduces the resistance of the jig and will not work.
7. Remove external sd, sim card and battery. Then replace battery and DO NOT touch the power button.
8. Carefully touch the two tips of the jig to the two copper plates of the micro usb slot closest to the headphone jack for about 3 seconds (this will also take some time and patience) *tip: use the other side of the micro usb port to brace against to hold the jig in place*
9. The phone should now go directly into download mode
9a. If your phone build number is BELOW 1010 continue following this guide.
9b. If your phone build number is 1010 or ABOVE follow this guide to flash back to stock.
10. Open odin3 on your computer
11. Plug usb into your phone, after odin says "added" click start to flash the stock rom.
12. Profit!
This fix as opposed to the others only costs $.99 and uses ONLY 3 resistors, NO CUTTING OR SOLDERING. Other fixes suggest hacking up your micro USB cable to use as a connection but i found that to be unnecessary.
As snapplefish has pointed out the desired resistance for this to work is 301K ohms, not 300K. HOWEVER, I and almost everyone else here has been able to only use the 3-100K ohm resistors. IF you are having trouble getting this to work, AND you have made sure you are using 100K ohm resistors, try measuring the resistance of your jig by using a multimeter. IF your resistance is below 298 or so try adding a 1K ohm resistor to your jig and remeasure the resistance of your jig.
Thanks to everyone who came up with the 301k ohm resistor method, saved me from a $500 paperwieght!
If this has helped you please give me a thanks
Cheers and happy flashing,
Alex

Dude, this is awesome. Thanks for pointing this out.

When is the next "flashaholics anonymous meeting"? I'd like to attend too

No prob, glad it was useful

Brilliant! Hopefully I never need to use it. This should go as/with/in a sticky.

I hope I don't ever need to use a jig but this is a great alternative to other methods. You do need to have the USB plugged in prior to touching the resistors correct since that is not stated? Common sense says yes but I figured I would be the idiot to ask haha

Well he's actually fishing around inside the phone's MicroUSB port to touch pins 4&5. So no, in this case...you don't need to have a USB cable plugged in.
But with other JIGs including mine, you plug the JIG into the phone.

Trying this tonight. Will update.

I have never been able to have Odin work without it being open and having the USB plugged in when getting to download mode. How will this work if you get download mode prior to the USB being plugged in for Odin to recognize?
This is my captivate. There are many like it but this one is mine.

I frequently use my JIG to get into Download mode to flash with Odin. For me, plug a JIG in to force Download Mode. Remove JIG, connect phone to a computer running Odin. The phone should be "added" in Odin and you should be able to flash away. I actually just did this last night as well.

True story. This guy makes good JIGs. I was very impressed with it. Tested it a few times and threw it back in the Samsung box.
I phone--/triangle\--PC bricked my first Captivate. Odin 2.1 got stuck on "Setting PIT" and I was able to return it (had it a week and claimed it did it on an OTA update lol). I had the 3 button download disabled (probably a 1008-1010, I have a 1010 now) and couldn't get into download mode so I could've saved the first phone but no one was building JIGs yet
Anyhow, I don't *NEED* it, but I'm GLAD I have it. I'd probably not flash without one.

For this to work, you need to have ~300kohm of resistance across pins 4 and 5 for at least 4 seconds. You cant touch bare metal on the resistors, or you'll change the overall resistance.
Yes, this is a cheaper implementation of a JIG, but it's also a little harder to use compared to if you were to just cut up a MicroUSB plug.

This isn't going to work for me. No metal has been touched, using exact resistors as described and touched pins 4+5 together. Oh well, new device should be here in 2 days.

I just opened odin, used the jig to get the phone into download mode, then plugged the phone into the computer and it worked. Make sure odin is open first before you plug it in though.

You are correct, this is cheaper and I figured it would take me about a half an hour to cut up the usb and another 3 to 5 days to recieve another one through amazon so this was a quicker way and maybe a tad harder.
This took me a total of 5 mins on the ****ter to make and 15-20 mins of adjusting and trying until I was able to get it to work. This seems like the quickest overall and easiest way to make a download jig, but if you have more money then time just buy a pre-made jig.

Make sure each tip is only touching ONE pin. They should not touch together or it will short circuit and not work. In my jig there is a small maybe 1mm or less gap in between each tip.

After messing with the spacing I was able to consistently put my phone into download mode. I also put some tape between the prongs to ensure they didn't touch.

Glad to hear it!
I also put some tape in between the two tips but wasn't sure if it did anything.

I always do it just never would work when I wouldn't have the usb plugged in at the same time of download mode. But if it ever becomes the case I will surely give the jig a try. Thanks for the info.

Updated first post with a youtube video of myself performing the unbricking procedure.

[HOWTO] *Layman's iGo Jig* [Solderless]

}
But YOU will NEED these:
And
Those two items is all you need to make this work, no soldering iron.
Now the reason I purchased the iGo adapter is cause of this guy here: As you can see, there is 6 pins on this thing.
Micro-USB has 5 pin connections. On a hunch, I was hoping all 5 pins were some how connected to the to the 6 pin adapter, so we didn't have to try and solder the resistor to pin 4, usually hidden in most setups.
Now the most difficult part of this whole process, was trying to get the micro-usb apart, which wasn't that hard at all.
Just take your time. I used a razor, scissors, and my teeth, lol. This is one part I didn't take pics, sorry. But try and "skin" (sort of like peeling) the black piece off.
Once that is off, you'll see a white plastic piece also around it, "skin" that one off too.
Once the white plastic piece is off.
The micro-usb connector and the 6 pin board is held together with a silicone compound that is bonded to the wires.
SLOWLY start picking the silicone compound away. It's really not that hard, just takes time.
Once that is done you should have some thing like this:
Now take your resistors and connect them in series: These are again, 100k resistor x 3. Should look like:
Now let's take a close up of the micro-usb connector. I don't know exactly which is which but I do know that both are pin 4 and 5!
Look at how long they are...that's what makes them special. Pin 4 is not hidden!
Since you got this far now just stick that bad boy in (please make sure the phone is turned off).
I should of cleaned up the wires but I was sort of in a rush:
VERY IMPORTANT: Don't let the other wires touch the connectors to the usb!
That image is with the screen facing me.
Now put in your battery, and take your resistors that you made and connect one end to pin 4 and the other to pin 5, not necessarily in that order.
Make sure you hold the resistors to the pin for at least 3 sec.
Viola!!! DOWNLOAD MODE!!
This was a quick fix for a jig that I needed to get MY phone working without soldering iron, and it worked. The hardest thing so far that I read about making a jig is getting to pin 4 that is usually not being used and hidden. At least this way it's easier to access.
I will end up buying another one and re-making my iGo jig to a more sturdier standard.
By all means, I am not a expertise in this field. I just been reading alot of threads and learn as I go.
So I am sure anyone can make this jig to revive their bricked phone. Trust me, if I can make it, so can you.
*edit: But if you have the chance, please pick up the 1k resistor also (not shown).
100k x3 and 1k resistor, this is the exact recommended ohms to make this work. 301k > It's the right way.
*I do recommend for those that have successfully done this, to (learn) solder the end pieces together. Pin 4 and 5 are long enough so it shouldn't really be that hard.
You won't have the tedious task of trying to manually connecting the two ends every time you want to go into download mode.
Plus I believe basic soldering skill is a must if you like tweaking or a hobbyist of electronic components.*
All the images were take after I was able to get it in download mode. Was not really thinking about doing this write-up, until after the last picture.
Hoping it may help the community one way or the other, and save some $$$
although a sloppy first attempt....this is GREAT knowing that there is an option out there. Thanks for doing the dirty work and purposely bricking your phone to help everyone else. Takes more guts than i have
Great thread. Thanks for doing this kind of thing for the community. I already felt comfortable that Odin could save me a lot of trouble, but now I feel like I can go completely nuts and not half to worry.
So I thought you had to get into Download mode WHILE the phone is plugged into your computer and ODIN is running.
If I understand right, you can use this jig to get into download mode, unplug the jig, and then hook up your phone to a computer and run ODIN?

Yes, you are correct. When using the jig, your phone will not be connected to anything, except the jig itself. But before using it, you should take out your battery, SIM, and SD (if you have one).
Plug the jig in > put in the battery > connect with resistor for 2 to 3 sec.
Once the screen is in "Download Mode" > pull jig > open Odin3 on computer > plug in usb to phone > then run Odin3 > done.

Yes I do advise to get it cheaper if you can.
But this is what I had to do to get it up and running that same night, just wasn't that important to me to save $10 for something that will get to me in a week. And I'm sure if you were in the same situation, you would of done the same thing to get your phone up and running.
But THANKS! I needed that link.
9.3% SALES TAX!!! FFFUUUUU that sucks.
9.3% isn't bad.. it's 9.75% here :T ..
and to sum up this article!
you don't really need to solder anything as long as you just rip the usb apart so the wires don't touch when you make your jig!
pretty legit mod, imma try and clean this up a bit and see if i can do a better looking job (no offense on ur job though!)
Another "How To"
What the.. duplicated post... weird.
Another "How To"
Alright guys, I bricked my phone last week (well, not bricked but disabled my 3 button combos and it was FCing on OS boot), and so I set out on the forums to find a clean-solderless alternative to getting into download mode. I didn't feel like dissecting a microusb cable, nor did I feel like soldering
This mod requires:
About a week wait time
A backup phone (if yours is already bricked so you have a phone to use)
A XDA and a Paypal account
First I found this thread (http://forum.xda-developers.com/showthread.php?t=819551) and went over to (http://www.sparkfun.com/commerce/product_info.php?products_id=10031) to buy a micro usb breakboard. It cost me about 9 dollars shipped to my door. I ordered it on Tuesday, and it got here on Monday (Thursday was veterans day, too). Came in a nice box in which I now store my completed jig.
Edit: Well the person I got my resistor from isnt selling them anymore, so you'll need to find someone to get it from =/ sorry! this isnt as useful then D:
Then you just plug in the resistor in slots 4 and 5 like so...
And you have a working jig. Really easy, works perfectly, and no cutting into any microusb cable. And now you also have this nice little box from sparkfun to store your jig in too. Don't forget to not touch the resistor when you insert it in your phone. Just hold it by the edges of the breakboard. This cost about the same as OP but just requires a little more waiting time. But it's so much neater and less troublesome.
Good Luck!

post 198, if you want to pay someone to make a JIG for you go here.
I have a bunch of parts for JIGs being delivered to me on Monday. After I make mine, I'm willing to sell the rest to people who need em.
wow that sparkfun jig is REALLY cool!! I don't understand why everyone is so scared of soldering though, unless they simply just don't have a solder gun (you should have one anyway).
I think i will order that sparkfun breakout and solder a resistor in for a nice complete jig.

the reason i didnt solder is because im away at college and all my tinkering equipment is at home (which is about an hour and a half away). i didnt want to buy new equipment just to fix my phone, nor did i want to wait til i went home again..
soldering is easy but it can be daunting if you've never done it before. i mean i've burned my self on my iron before and it was not a fun ordeal ahaha. otherwise from that, this worked quite nicely so i dont need to solder--saved me money and time
they are showing that board out of stock...you must have got the last one!
Since this thread was one of the ones that inspired me to make a Download mode jig, I thought I'd share what I put together today.
Made with a MicroUSB female plug, 300kohm resistor, & wire from a torn apart ethernet cable. I had originally planed for it to be half the size of what it is, and a lot cleaner (without a loop in it). But soldering to the damn usb plug was a pain, and the tins are fairly fragile.
It works like a charm though!

Looks great and clean work! I ended up purchasing 2 of the micro-usb break-out board, yet I still use the one that is posted to get me into download mode.
I don't know if it has any affect or not, but when I flash to stock with Odin.
I normally won't do a "adb reboot download". But I will turn the phone completely off, pull battery for 5min, then use the jig to get it into download mode, then restore.

USB connection, wear and tear

So after so many flashes of custom roms, kernels, modem, and etc.
Are you guys finding it harder for the micro-usb connector to actually get a tight fit into the phone? Mine's so loose that the slightest tug or movement will disconnect it from powering or connecting to my PC.
I slighlty fixed it with needle nose pliers , a more efficient fix anyone?
Im having the same issue
Sent from my SAMSUNG-SGH-I897 using XDA App
Definitely noticed this too. I notice my usb cord after a minute of being plugged looks like it's coming out a little.
I actually don't have this issue. I don't know how much you guys flash but I am doing something daily beyond just charging. I don't move my phone around much when it is plugged in.
On my phone, thin plastic piece around the usb port is cracked and i sometimes confuse that with the sliding usb door and tries to close it until i looked down to notice that it's not the door that i'm trying to close
I've noticed this recently too (I've had mine since July). On mine, when holding the phone normally, if I push the cable toward the center of the phone and it comes loose. If I push it outward (toward the volume buttons), it doesn't really move.
If I open the usb door all the way, plug the cable in, then close the door *slightly*, it holds the cable a lot better. Not like it did when it was new though.
Has anyone diagnosed the cause of this yet?

Actually I do not recommend doing it this way until other means are available, remember, ruin your usb connection = your screwed.
But it's the sides of the usb connection I'm trying to tighten up. Where it forms / \
Mines so loose, that if I do a simple reboot and move the wires too much it will give me the: ! to android guy pic.
If it's becoming loose its due to the plastic bezel around mini usb port. Eventually it will crack at where the door hinge has to pass through the part just before the door becomes secure when set to open position. Not sure if it's a plastic quality problem with a certain batch just order a replacement.
Secondly the usb cord supplied is not flexible at the handle for the miniusb connector. Flex it to much you will dislodge the data + - wires. Took it apart and inspected. You'll need to resolder to fix it.

I have a question though: When you say order a replacement, do you mean a new phone or the little plastic bay that holds the charger?
I also bought this phone at launch, and I'm sure that means I am out of any kind of warranty.
UNLESS!
Is there a year warranty on hardware defects?
You're still under warranty (1 year). You'll have to deal with a AT&T DSC for replacement.

So does that mean I should back up with Titanium Backup and flash back to stock?
cracks
My cappy has 2 tiny cracks on the top of it. One where you posted ( between the charging port and the back of the phone ) and another between the headphone jack and the back of the phone. They are so small no one would notice them unless looking. Returning the phone would be too much of a hassle for me ( I'm lazy ).
My idea was if the plastic began to chip or crack anywhere else I would just buy a bodyglove case and voila - no more cracks. And I didn't have to talk with an AT&Tard to fix it.

If you actually have physical damage to your USB port to warrant a replacement phone, yes...I'd say flash back to stock.
If you're trying to address any problems you have with the USB slider door, I doubt they'll replace your phone. You'll probably have to have it sent in to Samsung for repair, and shipped back to you. Of course if your phone goes to Samsung, you had better flash stock.

It's not the slider door. That is broken now too, but it isn't a problem for me. It is the USB cord won't stay in the charing port anymore. It is a bit of a hassle to wake up in the morning and my phone didn't charge.
For each usb wire that I use, I am now gently crimping the top and bottom of the usb connector to get a tighter fit. DO THIS AT YOUR OWN RISK THOUGH
It seemed to help me to get a tighter fit and now I don't have to check if the sucker is charging or not.
But yea, I was at the point where it would not charge my phone if I did not get it right, sucks I know.

^^^I also did that and it helps^^^
And, on the usb wires I use, there are little prongs, or tabs, that I gently pulled up with a tiny flathead screwdriver, actually a clean razor blade worked better... But I pulled those tabs up, and now I have a pretty snug fit.
And of course, do that at your own risk.
I started having this issue too where the lightest touch on the sides would bump it loose from the connector. In my case though I noticed that I did not have the door open completely all the way (yeah DUH). Once I pushed it completely open it fit much better.

I have flashed a lot and my phone is repeatedly connected and disconnected from USB at my desk all day at work and my usb still fits snug. But about 2 weeks ago the little plastic sliding door started sticking as I was opening and closing it and yesterday it finally just fell out of my cappy. Bought on release day last July.
I had this problem too, but it was the cable, not the phone.
Got a new OEM cable off of Amazon, and now it's nice and snug. Maybe not 100% like new, but pretty close.
Because of the little metal hooks on them, Micro USB cables tend to wear out much faster than the Mini USB cables of old.
I swapped mine out last week for another refurb (number two) because of this. It got to the point that I had to make sure the cable was in precisely the right spot otherwise out wouldn't charge.

[Q] “Loose" usb port?

Just wondering if anyone else's usb cable is a little bit "shaky" after being plugged in? I guess it's normal since i don't have any poor contact issue so far, but ...it's kinda annoying..
Sorry if you didn't notice it before but you do now
ye my last android did that too. after using the micro usb port a few times it gets "shaky"-er haha

My Epic 4G Touch is the same exact way. However, I never had this issue with my Evo. Wonder if its an issue with the ports on Samsung phones.
I have found taking a pair of pliers and adding some slight pressure to the end of the usb cable has helped tighten things up. Make sure you are squeezing the entire connector and not using needle nose.

Its funny that you mention that because the looseness seems to be more dependent on the actual USB cable than the port itself (at least on this phone) Luckily, I haven't had any real connection problems with my phone. However, after replacing the cable, it seems to fit more snugly. Either way, its a little odd that it the same cable will seem more loose in this phone, but fit just fine in my previous one (still have it as a spare).
I've been having this problem lately also. Thinking in was a bug in the rom or a bad cable, the problem persists and its getting worse to the point it constantly will connect and disconnect repeatedly. I'm thinking its the phone because I've changed cables, usb ports and it still does it. But sometimes it will stick normally. Wierd...
If you have even tried brand new cables (since your existing ones may be worn out), then I would say that the port on the phone is likely damaged. Looks like it may be time for a service center repair.
My SR is the same way. The mini usb cocksoff to the right. I've experienced the same with a few Motos. I've came to the conclusion it is the cables themselves. I have noticed that the two teeth on the male plug get kind of wore out or not even pop back out and furthermore eventually damage the female port to where the phone will cycle from power to no power. I've especially seen this with OEM cables. I also saw a thread here where the guy gives an awesome, detailed breakdown of a screen replacement. The site he links has the replacement chip with the mini usb port if you feel froggy...

Bricked i9023 ? Advice needed

Hi, today i tried to flash my first rom, i found a guide online and started following the instructions
1) i unlocked the bootloader
2) flashed recovery twrp
3) wiped device
4) installed hellybean rom
5) installed gapped
and then i forgot and closed the device, now the i9023 is dead it doesn't power on tried the unbrickable tool without performing the unbrickable mod and allways it responds "device is not detected"
Is this the situation of a hardware brick ?
Can i restore it with the use of software ?
Do i need to jtag it or the unbrickable mod will do just fine ?
Is there any guide to make a jtag cable or do i need to purchase it ?
Any help is really appreciated
I ordered a usb jib but i don't think it will work
Ok some more questions, the ubrickable mod will put the device into a hardware recovery in my case so i can flash the chip again ?
Should i perform the ubrickable mod or call it a day and call warranty as i have over 1 year left (with the hope that they will not charge me) ?
thanks

It happens to me twice. First time on HTC Desire and second time on Nexus S too. I didnt installed good kernel and rom and every time i turn on i shows me an error. How I solved it: I launched phone i fastboot mode, wipe all, and installed again all - rom(kernel) and gapps and it worked for me.

Can you put your device in fastboot mode (Power off and then press Volume Up + Power buttons) ?

Phone is dead bootloader is deleted can't power on the phone with a usb jig or any other combination of buttons tried several times !
The only solution now is to do a hard recovery mod so i can force the SOC to be visible and flash it again or Jtag it (that's the only viable solutions)
My problem is that the schematic Adam wrote about the unbrickable mod (i don't mean the software) is not clear enough. http://forum.xda-developers.com/showthread.php?t=1566475
I can't post on this thread cause i don't have the necessery posts
He says on the post : "2. Perform the mod as follows: Replace the xOM5 resistor from the top position to the bottom position.
*OR: remove the xOM5 resistor and jumper the center pads of xOM5 to the center pads of xOM0 or xOM3... I was not able to flash a complete firmware package to this device because it had a MMC failure, so I'm not able to tell you which point is which."
What does he mean replacing the xOM5 with top and bottom ? interchange the top resistor with the bottom one ?
And second option is to remove the resitor, bridge the points and solder on the upper pad. Why do i need to solder on the upper pad ? cause it's a more clear point ? I can solder directly on the bridge point, solder from the bridgin will be more than enough to held the cable
And lastly my though i believe i don't even need to remove the resistor just bypass it with the cable

The first option is not quite clear to me either, but the second one is pretty straight forward. If you look at the picture closely you'll se that the upper pad is directy connected to the "bridge point" (ie. the pad where the resistor was originally soldered.
I'm also having the same problem on my I9023, but I still haven't tried this mod. Can we be sure that this will work with the I9023 as well as with I9020T?
i will proceed with the modifation when my soldering tip arrives, the parts are small for me to do this without my hot air station but oh well i don't really care i will infrom for the results
Modification works, but the pc wouldn't detect always the phone, anyway i manage to flash the phone now it works ok
Use a soldering bit with really thin tip mine was 0.12mm enough to perform the operation and you will need a 15watt soldering iron i used a 25watt antex solder and end up lifting 1 pad but not a big problem
edit: forgot to mention don't solder the wire to the brown resistor but on the black one at least on my case that's what go the phone recognized. Initially i solder the wire on the brown resistor cause was easier but the phone was still dead then proceed soldering to the black one and i was able to detect it
I'm not sure why but if 1 point doesn't work try the other

congrats on your recovery i'll try this when i catch some time (and a weaker soldering iron xD ). thanks for tips. i don't understand why it didn't work for you with the brown resistor pad.

What do u mean by brown resistor?
Can u explain more detail on it?
Thank.

[Q] Juopunutbear s-off procedure without the original usb cable?

Has anyone been able to complete the Juopunutbear s-off procedure without the original usb cable?
I've tried over 20 times with a couple different paper clips in electrical tape but it's always sober.
I don't have the original. I'm wondering how "original" one off ebay will be. I wouldn't think they'd be able sneak anything special into the standard usb connector.
Lol. I s-offed my phone with a blackberry cable and a regular paperclip without insulation. It should work perfectly because I'm s-off right now.
Stock ICS ROM is required though.

Man, finally got it. Not sure what I was doing wrong. Not a long enough pause? Does the position on the sdcard thing matter at all? I used a large paper clip wrapped in electrical tape. Holding one end of the clip flat against the gnd with my thumb and then tapping the other end on the pin worked for me.

I don't the cable matters. I got s off with a replacement HTC cable (the original one I possess is most likely short circuited as all its internal wires are showing outside. It still could transfer data though).
For juonuputbear, the wire I used was so thin, I had to double it back on itself to make it thick enough for contact. For about 12 times, I didn't detect any change (not even wire trick fail) and then I got s off and I was like BAZINGA.
Happy to help.
