[Solved-BADUSB]I think I managed to brick this Captivate

I just got my Captivate last Friday. Hadn't done anything complicated with it, basically I just used "Unleash the Beast" to root and sideload the thing. Ended up with some sort of weird permissions issue going on with the SuperUser app that had been installed with it, I was getting permission request loops. So I used Odin to reset it. At this point there wasn't anything really wrong, USB worked and the device appeared to the computer. So I just rebooted the Captivate into download mode using adb reboot download and went on.
So later on I grabbed SuperUser 2.3.4(?) or whatever the latest one I found online was, loaded that to do adb pull /system/apps since I realized that Unleash the Beast just deleted everything and I honestly hadn't even seen what it removed yet on the phone itself besides the list on the web site. So after the backup I odin'd again and then grabbed the files from SuperUser 2.3.4 replaced the existing files in Unleash the Beast with it. Actually ended up working perfectly for a while.
I'd used the phone for a few days, no issues, finally got my 16GB SD card from my Raphael and inserted it, had been downloading apps left and right. Well all of a sudden the phone seemed to have it's USB stop working for anything but charging. I recall plugging it into a charger or computer when I first got it and it would ask if I wanted to mount the SD cards for use, then I would just see the battery indicator charging. and I'd toggled developer usb a half billion times trying to get access and fix it.
The computer didn't see it, device manager didn't even flinch(Win7 x64) like it normally does when you plug in and unplug a USB device. Tried it with another computer and same issue. So I rebooted into recovery mode and tried that, the first several times around nothing was detected. Well my finger slipped and ended up hitting the Clear user data and cache option in the recovery mode.
At this point when it boots up, i still dont have usb access, I'm stuck in a force close loop, I can't install apps, can't seem to get it to reboot into download mode via the key commands, and installing apps is impossible since browser and market crash on start.
I've spent the night rebooting and trying to get into download mode for odin, I used to be able to get into recovery mode everytime I tried, eventually I started to see an "uknown device" show up in device manager, which I googled some info from it and all I could tell was it was Microsoft's dummy driver for devices that couldn't be found. Another weird response, it seems to be beginning to hang on the charging battery thing from time to time now.
At this point, its been under a week and I'd trade it in. Except the thing is with enough struggling you can see the apps installed. Most of them were removed but Market Access and Superuser are still in the apps list, and I'm worried about AT&T spotting that, figuring out what I've done and rejecting the claim.
just under half the time now, it boots, the other over-half of the time I get the spinning "battery loading" icon that shows up before the battery thing gets loaded, but not spinning. It pops up, and disappears, from time to time goes to show me my battery status instead of booting, even when not plugged in.
I'd like to think I haven't tried everything? quite obviously i can't run update.zip files from my 16gb sd card since it gets mounted at /sdcard/sd, and I've lost the file browser to move anything around. I've tried rewiping but that doesn't do a thing.
I hadn't gotten to the rom manager stuff yet since I wasn't planning on playing with roms if at all. and at this point that doesn't appear to be an option anymore.
Any suggestions? I was getting to continuing to reboot it till the battery thing comes up 100% of the time then goto ATT and see what they say.

So long that you can get to download mode you SHOULD be good. When you plug in the usb..you need to pull the home dropdown..select usb and tell it to mount. I may be telling you what you already know but download mode is hold both volume buttons from the battery screen...one black screen...att screen...black screen and release pwer but hold buttons. I had problems with this so what I did was unplug the usb...volume buttons...hold power and see att boot screen...(plug in usb)...black screen...att boot...black screen and release power til u see download mode. You can use Odin and set back to stock from there normally.
If the PC is showing unknown device..you are kind of stuck til you fix the driver issue. Maybe remove and reinstall or something not sure on that but that's the first order of business. Go to the dev forum and try reinstalling from there. (One click Odin downloader has teh drivers)
If your phone boots or can get into recovery or download mode you are ok. I ran into the problem where I couldnt even power it on.

Well by now I know that download mode is the holy grail to get things fixed. Recovery mode, I used to be able to get to, but didn't show up. I'm wandering if somehow my USB port got shorted or something.
The drop down option to make it mount is why this all began, it disappeared and never came back.
Trying your steps specifically, first couple times would just end up back at the battery screen. I eventually ended up at recovery mode. Did I end up at recovery mode for releaseing early or late?
I've reinstalled the Captivate drivers a couple times now and tried clearing all past installs of it. Still unknown device. At the moment I have it in recovery mode, so I've rebooted my tower into Ubuntu(Which has the sdk, but never tested with it). Since I've kept reading that Linux doesn't need drivers. Well ./adb start-server and ./adb devices still show nothing...
I can grab a fresh computer that never connected to this thing to try, but I'm kinda doubting it will do this trick at this point. I'll download the odin w/ drivers on it and try that.

hmm.... just ran over to one of the computers here that had absolutely nothing to do with android on it, no drivers, no sdk, no software, nothing.
Went to
[STOCK ROM] Odin3 One-Click Downloader and Drivers(new user=no links)
Downloaded the Windows X64 drivers, installed and rebooted
Plugged the phone in after it rebooted and I'm getting
Unkown Device, I'd pull some info from the Device Manager, but all it is reporting is scewed due to it being a usb device and Windows installed dummy drivers.
All I've got left for testing is my brother's Win7 x32 laptop, granted all I've been able to try with here has been x64 so far. Also on the first computer I was doing all this with. The drivers DID work, they WERE installed and functioning. Previously I could ADB to my hearts desire and I've used odin before. I used the same USB port, used different USB ports, tried different cables.

I had some strange issues on mine. When I would try to go to download mode. All of my USB stuff (KB and mouse) froze up and I had to plug in via PS2. I had the unknown device issue and Not sure how I fixed it. I downloaded and installed the Samsung Kies program and I also downloaded the driver. Ultimatly after banging on it for a bit it worked..not a Unknown device but it was some king of...Gadget Driver or some stuff was messing with me. Try installing Kies and see if that does anything...also make sure you remove the drivers before installing. It acted really squirrly to me too tho. From what you say..it sounds like a borked driver. Im on 32bit XP and took it home to my 64 Vista and got it working whne the 32 was jacking me around.

Just had a chance to try with Kies real quick, I'm not so much thinking i killed my drivers but that somehow the cell phone changed it's id calls. I'm going to give it a shot with kies on a fresh Vista x32 system at work. I still can't seem to get it into downloader mode, but I'm getting more consistent with Recovery and getting the thing to boot back up. If I consider the Battery screens to be your blank screens then I can get it to go recovery or "normal" boot. But still can't seem to get download mode at all.
Up until recently, I didn't get Unkown device showing up even when the system was in "normal" boot. Before, originally it would only show up in device manager in recovery mode, and then it would be the unkown device.
Just out of curiosity could you spare the driver specs for your setup so I can compare? Like Date, Version, and any Hardware IDs? I'm wandering what hardware IDs this thing is giving off since windows wont show me.

Well not sure what suddenly happened. But after enough reboot--attempts, recovery mode is finalyl appearing on my office computer as SAMSUNG Android USB Composite Device. Win Vista x32, only installed Kies and download SDK(speaking of, adb still doesn't see devices). Just finished redownloading odin(wish i'd had a thumbdrive on me when i was at home) and am about to see if I'm going to be lucky by vista somehow.

If you still keep having issues find a way to short the phone out and tell at&t that the phone just got really hot and then turned off. They should replace as a bad unit and get you hooked up with a new one.

Well that thought has occured, that and magnets lol
I think i might have found a clue to the cause. I think it was tied to the whole usb thing. When it appeared to show up at all first time around, i had tapped the menu button while in recovery. And the natural way I'd been holding it applied just a little pressure on the usb cable. Well I got the phone to finally show all the notifaction tab options for debug and storage when i held down the usb plug in the phone down a little bit. I'm guessing that the pins for power are fine but maybe the data pins, or maybe one of the data pins is loose and thus it's an unkown device since it's not responding correctly.
I didn't have time to finish trying to fix it at work, and i'm stuck in class now. I'm'a see if i can get admin access on my terminal here and download everything while the teacher does his orientation. Otherwise i think i can fix it once i'm home now.
=====EDIT=====
Well getting the phone into Download Mode was a bit easier with Ubuntu via ADB since I don't have to wait for Windows to load the driver. Then just rebooted the box into windows for Odin. Long painful story short, I didn't setup Rom manager to be able to undo my changes when the USB port went bad/inconsistent and didn't expect those changes to complicate the recovery without USB. So I'm making sure it's a rather provable issue and going down to ATT with it. 7 Days from receiving the phone, and I'm goin in for an exchange due to bad USB. Funny.

[Q] Connect to Computer and get Code 43 USB Malfunction

I've had my Transformer hooked up to my computer before, and it's been fine, now I hook it up and i get code 43 USB device not recognized, device has malfunctioned. I really haven't done anything to it lately, but i did have the power go out at the house when it was plugged in charging to the wall. I didn't really see anything on the net and i've done all of the normal stuff, restart, unitstall, reinstall, and manually delete out of registry, everything, factory reset, different ports, different computers, different houses even, it's weird. And i'm a computer tech, I ususally don't post because I eventually figure it out or find it on the net, but i'm stuck. Unless i have completly overlooked something, BUT I'm pretty sure I didn't.
I did have a problem over the weekend where my vol - button got stuck and kept going into recovery and i couldn't get it out. Finally fixed the button and got it to boot and got stuck at Android "Enter password" which i don't have any clue about, or know the password figuring out that it wasn't related to my google account, so I went into recovery and factory data wipe and been stuck with the USB problem since.

[Q] Problem with communication during GB update

Alrighty,
So I keep trying to update my g2x through LG but I continuously get an error message that says, "Problem with communication between cell phone and PC", and then it never goes past 4%. Yes, I've downloaded the proper drivers, and have followed the prompts of disconnecting the phone, removing the battery, powering back and pressing restart (countless times). None of it works though. And no, my phone isn't bricking up on the SW update, so that thread doesn't really help me.
I've been doing some research and it seems that it just doesn't work for some phones, but I'm wondering if anyone here has been able to successfully troubleshoot this.
Yeah, I'm one of the unfortunate ones that got a bad phone a while ago, so I'm hoping I can find a way to make it work...
Thanks in advance!!

I have had the same problem. I have a G2x that I got off ebay. It was un-moded, running stock Froyo 2.2.2. I went to the T-Mobile / LG update site and followed the steps. The program actually worked the first time, it went through the whole update procedure and said it was complete. The phone restarted, but when it restarted it no longer recognizes the SIM card and there is a question mark for the battery symbol. When I go into the settings, it does not show a baseband version. I have tried to re-install using the update program, but it stops after 36% saying "Problem with communication between cell phone and PC". Any ideas?

Mine did this the first time. This is where the phone is never commanded to boot into S/W update mode so at least this is not a step where it can be bricked, as no update has actually occurred yet.
This is how I fixed it and got mine to update. Use a different USB port on your computer. Yes there are different as some are on internal hubs. The update must have a direct USB port with no hubs in between. I also reinstalled the drivers through the LG Update program and not from the LG website. When I did this and plugged in my phone about eight new devices were detected and installed as opposed to about two the first time around. Also, make sure your phone is in debug mode in Android application settings.
Then make sure you disable any anti-virus programs and turn off the Windows firewall. Then use ctrl-alt-delete and close down any programs running. Also go to the taskbar and click on the up arror (if Windows 7) and right click on each icon and see if you can close it down. Also, unplug all other USB devices (even a mouse if you don't need it) as they can interfere with communications between the updater program and your phone. The only USB device I left connected to my computer was the keyboard.
The LG Updater must be run in Admin mode. If when you run it you get a Windows warning asking you if it is ok for this program to make changes to your computer then it is launching in Admin mode. If not right click the LG Updater icon by clicking Start>All Program>LGMobile Support Tool>LGMobile update. Right click the last item and run it in admin mode. Again this is assuming you are running Windows 7. Admin mode is not necessary for Windows XP.
If all the drivers get loaded properly and you are not on a flakey USB port then at 4% the updater instructs the phone to reboot into S/W Update mode and that is where the real magic happens if you are lucky.

Use another USB port and try again. At various points in the update the updater resets the phones usb port and it has to reconnect. If it doesn't connect don't do a battery pull. Just try removing the USB cable and reinserting it. If you hear the computer beep wait a bit and then click restart on the updater. Hopefully it should see the device this time and continue the update.

Wont connect to PC and other odd issues

Ok, so I have been having a very annoying issue(s) recently with my SGH-I997R, ( Firmware version 2.3.3, Baseband version I997RUXKG3, Kernel Ver: 2.6.32.7-I997RUXKG3-CL366622)
This all started out of the blue about a month ago, I used to connect my phone to my PC all the time for transferring items via Mass Storage, and then on day when I went to connect it to my same PC, I got " USB Device Not Recognized". It will charge the phone but will not connect or show any option on the phone to connect. I have tried 2 Samsung cables and a generic Micro USB cable, No change. I tried connecting to my laptop, same issue. I re-downloaded the drivers from Samsung onto both my usual PC and Laptop, no change. Very very frustrating.
Other issues, I don't know if their related in any way but they all started at the same time.
a) if I place my phone in airplane mode i cannot get it out of that mode without rebooting my phone
b) if i shut my phone down (doesn't matter if battery shows 100% or 25%) I cannot get the phone to turn on without plugging in the USB cable.
c) When I leave my phone charging overnight and look at it in the morning, battery shows 100% but also shows "NO SERVICE" , I reboot the phone with the cable still connected, service restored.
IF anyone has had these issues Especially the connecting to PC issue, Please PLEASE help. I am going nuts. And of course this all happened 3 months after the warranty expired, so both Rogers and Samsung will not help without $$$$$.

have you tried to back up your data, take out any micro sd card and perform a factory reset under /settings/privacy/reset ?
or open it up and look inside for any problems like corrosion?

I have done a factory reset numerous times from both the /settings/privacy/reset, and from booting it up holding the volume keys and doing a reset that way.
And I have had my phone since day one in a Ballistic Hard Core Series case, I take it out once a week to ensure its clean and free of dust/moisture (I work in construction so I try to keep it a clean as possible.) and my phone still looks like its brand new.
Thanks for the response though,

Update:
So just as an update for anyone out there who may be able to assist me with this very annoying issue, the Phone is still doing the same things, and since the last post i've also replaced the battery to see if for some strange reason it might help.
But to no avail.
As well I dont think i mentioned that this phone is rooted. I want to try unrooting it to see if that will correct the issue, but with not being able to connect the phone via usb to the computer, I have NO IDEA on how I can accomplish this. Any help???

Samsung J7 Prime G610M - FAP Lock + weird usb problem - Urgent

So, something very weird started happening to my phone. Out of nowhere, about 7 hours ago, it would stop charging whenever it was on, charging only when it was off and connected to my laptop. However, I thought it was just something wrong in the dev options, and I went to change whatever was the USB option to "charge phone". With this, I did accidentally forgot to activate the OEM option, and had to reboot not long after. You can probably see where this is going now.
Now I have a phone that bootloops on the FAP Lock message, and whenever I go to download mode to fix it, my PC just doesn't recognize the Phone. I've tried different USB cables, all of them are only recognized when the phone is shut down. So it isn't a hardware problem, because the Phone actually charges when it's shut down, and it isn't a problem with my USB ports or cables, as anything else I use with it works fine. And the worst part is, I need this phone today for a serious bank matter, and I can't afford to lose any data on it either, there's some very personal important stuff from yesterday that wasn't backed up yet. And keep in mind that paying for it to be fixed is the last option for me, as I can't afford it (besides, I fear they might end up getting the phone in factory reset mode, and I can't lose that data as I said).
Any kind of suggestions on how to get either the PC to recognize the phone, or flashing in a different way that doesn't need the PC to recognize the device? Thanks in advance.
Edit: Whenever I try to connect the phone via USB, it doesn't even make the Windows "USB connected" sound, it's just like it isn't there at all. One time, I got it to show, but it was as a "unrecognized usb device", and I haven't been able to replicate it yet.
