[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] Volume Down Method Not Working for Odin

Just spent the last couple hours going through the rooting process, except for I never got the chance to flash CWM. The volume down button is not working to bring it into download mode. I know the button works when the phone is on, so it's not a mechanical issue.
I installed/uninstalled the Samsung drivers a handful of times, even grabbed the official file from Samsung's site. Restarted, didn't restart, ran Odin as admin and not, tried several USB cords, and several USB ports, and still nothing. I got it to go once, held til the COM port showed up in Odin, but then the phone randomly disconnected and got an error from Windows says drivers not installed correctly.
Any other ideas to try? I am coming from a rooted OG Droid, so it isn't my first time, but I am by no means an expert.
Thanks in advance.

Download terminal emulator and allow su permissions
Just type su, allow, restart app.
Type su, then reboot download

The Charge is kind of touchy about download mode, I've noticed.
Here's what you can do.
1) Turn the phone off completely, unplugged off the charger.
2) When it is off completely, plug in the the USB cord and hit the volume down button at the same time. Hit the volume down button constantly many times until download mode finally kicks in.
ALTERNATIVELY -
You can download "Quick Boot (Reboot)" from the market. This will allow you to boot into Download Mode or Recovery straight from the app. Only if you're rooted though.

why not try another computer? also, are you using a laptop or a desktop. if you are using a laptop, make sure it is plugged into an outlet. (If on Vista or 7) Make sure your power settings are set to balanced or high performance (not sure if this affects USB ports but it may).
In addition to all that, what version of ODIN are you using?

I'll just tell you what I know works from experience.
#1: Turn the phone off and wait 15 seconds(it needs to completely shut off)
#2: Remove the battery
#3: Open Odin
#4: Plug the phone with no battery into the back USB port of your desktop(if you have a laptop just use any port)and while its plugged in just hold the Down volume control for a few seconds until a yellow triangle pops up on your screen but DONT let go until one of the rectangle ports in Odin turns yellow as well, then you can let go of the Down volume button.
If that doesn't work then I can't help ya D:

I am using Windows 7 desktop so I'll check my power settings tonight.
Odin should be v1.3 IIRC. Laptop had the same issue which is also running 7 so I'll need to check settings on that as well.

Thanks for the other replies as well. Tonight will be attempt 2. Touchwiz is unfortuantely growing on me, but having the bloatware is really annoying me. Will probably run stock for a bit then flash gummy charged.

Got it working finally. Had to have the battery in the whole time otherwise it just kept failing.
I am now rooted and nearly debloated! Thanks for the tips.

[Verizon] If you're still having MTP driver/USB connection problems...

I may have found one more thing you could try...
After trying EVERYTHING I could find here on XDA, as well as across the web, I still couldn't get my S3 to connect to my computer. While trying to get mine to work, I discovered that my husband's S3 connected just fine, nixing the thought that it was computer related. I exchanged mine for a new phone, got it home, and it still didn't connect.
Several hours of troubleshooting later, I had it narrowed down that it worked immediately after a factory reset (while still connected to the computer), but BEFORE the setup wizard got to the Backup Assistant (where it was no longer visible in My Computer). SO, I reset it again, skipped out of the setup wizard as soon as I could, and bada-bing! It works! I discovered after the fact that my husband (whose connected so beautifully from the get go) had backed out of his setup wizard during initial setup, so it definitely could be more than just a one phone fix.
I'll be the first to admit that I'm a total newb to pretty much everything in this forum, so there may be a more knowledgeable person who could be able to pinpoint exactly why the setup wizard would prevent the MTP driver from working properly. At this point, I'm just happy it works, and wanted to put this out there in case there may be anyone else at their wits end.

I had to install kies before it worked properly for me and now i still have to plug in phone then unplug and plug back in before pc see's my phone.

Yeah, installing, uninstalling and re-installing Kies did nothing for my phones (first or second). I tried it all -- different usb ports on the computer, battery pull, reboot the phone, reboot the computer, install the drivers, uninstall the drivers, try it with usb debugging checked, try it all again with usb debugging unchecked, with an sd card, without one, with a sim card, without one, factory reset not connected and then factory reset connected. Even tried it all again on a separate computer running Windows 7 vs Vista. Finally, in the middle of a factory reset, I saw the magic words "Installed Successfully", but then it stopped working after I finished the setup wizard. Again, I have NO idea why the setup wizard would cause it not to work, but that was what I had narrowed it down to. I'm just glad to have it working!

Well, after reading about a dozen posts and so-called fixes. It all boiled down to uninstalling the Samsung Driver & Kies (if you installed separately). This def works for Verizon SCH-I535 Galaxy S3 16MB with 4.0.4 load.
1. Uninstall Kies, Uninstall Samsung Driver, reboot. Reboot your phone just to be safe.
2. On your S3 select Settings-->Developer-->Enable USB Debugging (hit ok at the prompt). Don't tweak anything else here. You MUST have the Debugging turned on for phone to connect to PC.
3. Plug-in the Samsung USB cable to PC (there was some discussion on which USBs work and which don't ... so you can try different USB ports if #4 fails to work below)
4. Windows will then install whatever driver(s) it needs and whala, you can now access your S3 via Explorer...it will show up as a phone, not an actual drive.
Hope this helps and saves you the time and frustration I experienced. I never saw the little USB icon on the S3 until I wiped all the Samsung and Kies drivers from my Win 7 system & enabled debugging on phone. So the issue lies with Samsung and their crappy Kies tool...their driver does not work for S3 (i.e., the standalone download that Version posts on their site). Go with the Windows Update driver (which is auto) and you should now be able to connect via USB to your S3. Again, this works for Win 7 32bit with Android 4.0.4.
-Cheers!

I have an old pc running xp. Nothing worked until I installed kies on both the phone and the pc. YMMV.

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???

Note 4 Bootloop - Softbrick

First, I will say that I have done an extensive amount of searching and reading about boot loops and issues with the Note 4 before posting this. After days of dead ends, I have to ask for help...
About a week ago (end of January 2017), I installed the Verizon security patch update for Android 6.0.1 for my Note 4 (SM-N910V): MMB29M.N910VVRS2CQA1. Everything was normal until this past Friday night, when I used a flashlight app (had been installed since I had the phone and used often) and it spun into a bootloop. Battery was at 20% at the time, and since I've had the phone, the battery quickly discharges below ~15%.
Situational Details:
Anyways, the bootloop goes all the way to the home screen, and often the touchscreen is active for a few seconds (varies) before it freezes for 5 seconds and continues the bootloop. It's worth noting that during the bootloop, the screen gets incrediby hot at a specific point: horizontally across from the power button and vertically below the light sensor.
Also, I'm able to access the recovery menu, download menu, and boot menu. Also, when a power cable is connected to the phone (with battery inside), the phone screen shows the empty charging battery symbol and then immediately turns on, without me having to press the power button. After that, the only way to actually power off the phone is to remove the battery or let it bootloop until it dies.
So far, I've tried the following without success:
-Wiping partition cache
-Factory data reset
-Flashing stock ROM with Odin. Though Odin recognized the device in the USB port and it accepted the ROM which I loaded it with, there was no activity from Odin to the phone once I clicked "Start". I'm using the original USB cable that came with the phone (the one that I charge it with), and the USB port is working fine.
-Using Kies3/Kies2.6/Smartswitch to revert back to factory stock ROM. Though Kies3 is allegedly the correct software, they all display an error message that my device is not supported, when I attach a USB cable to my laptop from my phone (regardless of USB port).
-When using Kies3 to try Tools > Firmware upgrade and Initialisation, Kies accepts "SM-N910V" as the model number, but it displays an error message that my S/N is incorrect, though I am copying and verifiying the IMEI from under the battery compartment (I also registered my phone with Samsung using this IMEI, so I know it's valid).
-Wiping partition cache 5x + Factory data reset 5x before rebooting
When in the recovery mode, the current android version MMB29M.N910VVRS2CQA1 is listed, which I find incredibly bizarre, since I thought it would have flashed to the stock ROM after a factory data reset. *shrug*
It's crossed my mind that the exceedingly hot temps may be causing the boot loop, but genuinely do not know if that's true or why it would become so hot in the first place. Either way, I just want to toss the idea out that maybe I have a hardware issue that's causing such overheating.
Anyways, at this point, I'm totally confused about what to do, especially since it's not totally bricked. Any/all help is greatly appreciated.

Anybody have any thoughts at all? I'm more and more open to the theory that it's overheating and causing a boot loop. When it's been sitting for a long time at room temperature, the screen remains at full brightness on the Verizon splash screen, and does so until it gets stupidly hot near the microSD / SIM slots... then it boots up for ~5-15 seconds, freezes for 5 seconds, and boot loops again.
I may try to thoroughly wrap my phone in plastic wrap and apply an ice pack before attempting to use it again. I find it hard to believe that the culprit is batteries since the issue happens with both batteries that I have (purchased separately at different times).

Ok, I had my Note 4 totally cold yesterday and booted it up normally. I discovered a few things while playing with it:
When the first reboot happened,the usual hot spot was hardly to room temperature. I tried this exact same test again this morning, with the same results... the hot spot was not even to room temperature when it froze and rebooting.
It's worth noting that I figured out the screen does not freeze if the display is constantly moving, regardless of phone temperature. For example, I normally try to do something/anything prior to the phone freezing and rebooting, like establish a file transfer type usb connection to my laptop, instead of the default 'charge' type connection. Well, to go through the settings menu and pick out the connection type, the screen will always hang for a split second as it loads the next set of menus. Normally, it would freeze at this point and reset. But today, I decided to click on the Apps button and oscillate my finger on the screen to flip between pages of apps... and it worked for several minutes straight.
I know my problem seems incredibly strange, but do any of these symptoms have any plausible explanation? I'd hate to think there is literally nothing that I do and that my $$$ Note 4 phone is now a brick.

Do you have USB debugging turned on? Do you have all of the USB drivers for Samsung phones installed? Are you using the stock USB cable when you use Odin?
If you can't get Odin to flash your firmware(it has to be the same version you have or newer, it can't be older), then you may have a hardware issue that is a result of the excess heat you mentioned.

I didn't have USB debugging turned on before. I turned it on (under developer options... which I barely have time to access before it restarts), but now both my laptop and desktop won't recognize the device via any USB port. I do have the USB drivers for Samsung phones installed and have re-installed them a few times, to be safe. Also, I am only using the stock USB cable when doing any of these things.

Does the device show in device manager? What is it labelled as in device manager?

Assuming you mean the device manager in Windows, it's only showing as "Unknown USB Device (Device Descriptor Request Failed)".
Two new interesting notes:
When I enter Maintenance Boot Mode (Down Volume + Power to boot) and select USB Debug Mode, it now just performs a normal reboot. I can't recall for certain if this was any different in the past.
When I have the ability to access Developer options, I can definitely see that USB debugging is checked. Also, when I select 'USB configuration', 'charging' is pre-selected by default. When "MTP" (media transfer protocol) is selected, the developer mode menu still displays the value as 'charging', even though subsequently accessing the 'USB configuration' sub-menu shows that MTP is selected. Weird.

Have you tried booting to safe mode, if it boots to safe mode then it's a user app or a user app update that is causing your bootloop. In safe mode you can uninstall whatever app or app update caused it.

Yeah, I thought about that, too. I've tried safe mode even after factory resets + cache wipes and it still boot loops. ("Safe mode" does indeed display in the bottom left of the display/GUI) Good thoughts, though.

Starting to sound like a hardware issue.
