[FIX] For those that haven't been able to get to Download Mode

If you are having problems getting to download mode, Use the Stock Captivate Cable Only when trying to access Download mode!
Story:
I have struggled with 2 captivates now to get into download mode. I have read tons of arguments back and forth from people that say it is easy to get into download mode, and people who say that it is impossible with their phones.
Well, for some history...On my first captivate, I bricked it and it refused to go into download mode...PERIOD. I proceeded to exchange it(I was within my 30 days), and didn't think much more about it. Well, I installed Cognition 2.2 recently and in the process realized that my new phone would go into download mode just fine by doing the standard process of:
1)remove battery, sim, microsim
2)reinserting battery only
3)holding down both volume buttons
4)inserting usb cable
No problems right? Well, I ended up "bricking" my phone by accidentally deleting my framework-res.apk file(don't ask) and lo and behold, I suddenly could not get it to go back into download mode. I was really pissed at this point and spent all night trying everything all over again.
Well, I decided to give up for the night and go to bed. As I was laying in bed a thought crossed my mind. I had purchased a second usb cable(from ATT) to use with the captivate, and the one time that download mode had worked, I was using the standard captivate cable that came in the box. However, every time it wasn't working I was using my second USB cable. So I got up out of bed to try the stock cable and, lo and behold, it works flawlessly every time.
I would venture to guess that this is what the problem is with most everyone else that can not get their captivates to go into download mode. So, if you haven't tried it give it a shot. And certainly tell everyone you know to use the stock cable only.
I just want to reiterate that the spare cable that would NOT work was purchased from ATT and is the cable that they recommend you purchase as a spare. It wasn't like I got it from ebay or something.

Using a usb cable I got from ebay, monoprice, htc, motorola, and stock samsung cable, I was able to get into download mode everytime...
... also, shouldn't this be in general and not in development?

No USB Hubs or Extenders
RECOMMENDED: Use your stock USB cable that came with the phone.
IMPORTANT: Plug the USB cable into your computers native motherboard USB port (the back of your computer). Plugging the cable into USB switches, extenders or external ports, does not allow the phone to enter download mode correctly.

I can confirm, although i found this out a whilllllle ago, just didnt think much of it lol

Just so you know. I found that in some cases certain USB cables just will not work with some devices. This has to do with the quality of the cable. I would avoid overly thin or flat cables because they tend to be cheaply made and won't be able to provide a stable power flow. The shorter the cable the better.

The cable he/I bought from AT&T is shorter the the cable that comes in the box, and doesnt work, so im not sure if shorter is better

I can recreate this over and over again. The reason I put this here and not in general is because I, like many others, have struggled over and over with odin, and people had the attitude of "it works every time, you're just doing something wrong." The reality is that you're trying to prove that I'm just "doing something wrong" because all your cables work. I can recreate this over and over again. What do you want me to do, make a video of it in order for you to believe that there is an actual issue?
I think it's important for people to see this when trying all the roms and mods that are in the development section. In fact, I think it would be REALLY helpful if designgears would add this to the "how to get to download mode" section on the Odin thread. I can't tell you the amount of hours I have spent trying to get into download mode. It is incredibly frustrating to do everything right, and have others telling you that you are not doing it right.
I searched google endlessly looking for a solution to get into download mode, and no where did I see this as a possible solution. Also, as an FYI, when I plug in the other cable, it just goes straight to the battery screen no matter what I press. I can hold down the power and volume buttons to go into recovery mode, but it's impossible to get to download mode.

I have plugged mine into a usb port in the front of my computer as well as in my monitor. I have never had a problem with download mode or anything else.

While this is good to know...It is quite possible you got a faulty second cable, and some of the cables that do come in the box are faulty as well..
It's always a good reminder to try changing out cables if your having an issues. Same for downloading different things that work for a-lot of people and not for you/me..same too for hooking into the back of the computer and bypassing the external hub....Sometimes you get lucky and find the problem right away..sometimes you don't....It's called a process of elimination...
FWIW..I've never trusted cheap ass cables..in anything. Never have..Never will..but..JSYK..expensive cables go bad from time to time too
Thanks for the reminder

I've also noticed that, on my PC at least, my front case USB ports don't always reliably work with this procedure. I've been plugging the USB cable since into the USB ports on the motherboard.

The thing that throws me off is that this cable works for EVERYTHING else. Data transfer, media syncing, recovery mode, charging, etc... There was never anything that would indicate any issue with the cable. I just want to make sure everyone knows this, because when I was struggling to get into download mode, I didn't see anyone suggest that it could be the cable, even though the cable worked for everything else.

OP - thanks for posting this! It is at least another thing to keep in mind when troubleshooting. I was actually considering getting another cable to keep at work.....
P.S. would we get in trouble for quoting Michael Scott's favorite joke in response to post #6? Yea, I know. Little too obvious right. I'll restrain. Already made myself chuckle anyways

Um.. not true - Although I did use the stock USB Cable - I was flashing the night away (trying to recover my bricked phone) on my Win7 box using a USB hub that had a few other devices hooked into it.
Never had an issue getting to D/L mode.. and it found the phone again and again and again and again.... (go on for infinity).
I think it has more to do with the hardware your connecting it to and how the USB drivers loaded (i.e. XP=****e) and what type of OS your running more than anything. I had terrible luck with my work's XP rig... but my Win7 x64 rig found the device while in d/l mode - found the drivers?!?! and I was good to go.
Although - it is always a good rule of thumb IF you can't get the device to recognize on your computer to use the original cable and hook to the best source of power for your USB which is the back of your computer.
So.. this isn't a [FIX] - just a good tip. If you can't get into D/L mode by holding the volume button and jamming in the USB or using ADB -> Reboot Download command.. your pretty much fux0red.

I need original USB cable
I just wanted to throw in my $0.02 I needed to use the original USB cable and a port directly on my motherboard. The usb cable I bought from newegg does not work with my MSI X58 motherboard and my capitavate. The original cable does not work if I use a front usb port on my Antec P183 case. Strangly an identical usb cable from newegg that I ordered at the same time does work with my work computer, Dell X38 motherboard.

Ive had the same problem... only way i get it to download mode is via Terminal:
su
reboot download
I really cant get it to work no other way :s

honestly, i have my phone cord that came into the box, connected to an extender cable, that's connected into a usb port hub so i don't agree with what you're saying here
mine works every single time

I appreciate all your hard work on everything. I read through that post and tried to search it several times... Believe me, I spent hours pouring through the pages looking for something that would work.
No where did I see anyone say to make sure you were using the stock cable because other cables might not work? Feel free to correct me if I'm wrong...there are a lot of pages after all.
Furthermore...I'm sorry to be new to Android and to flashing roms, but we are all new at some point. No one is born an expert.
edit: I'm guessing you misunderstood the post? I wasn't posting about the method...just about the fact that many usb cables, including the micro usb cable that ATT sells, do not work for getting to download mode. If I'm wrong about what you were posting, feel free to correct me. If i'm correct, your post is quite ironic

The first captivate I had WOULD NOT GO INTO DOWNLOAD mode regardless of cable or usb port. I tried every port and every cable including the stock one that came with the phone.
The replacement captivate ALWAYS goes into download mode regardless of cable or port.
It's a tip and thank you for the. But if your phone is one of those that does not have 3 button recovery then it will likely not work with the 2 button download trick either.

[Q] usb debugging failed

USB debugging no longer activates on my phone. Activating it in settings/applications/development brings up the "Allow USB debugging?" permission window. However, no usb notifications appear, and the phone appears to be a dead device to any PC it is connected to.
This started when I accidently got into the download screen from the phone options popup. The display showed the yellow sign, android guy with shovel, and message warning not to turn target off. Phone was not connected to anything at the time.
Searching found a couple of threads indicating that a battery pull was safe to get out of it. Did same.
Since then, usb debugging (or usb anything) has been dead on this phone. Other methods of usb access (thru usb settings) have no effect either.
Tried the following...
(1) restore to my last backup rom.
(2) numerous reboots and battery pulls.
(3) mount/unmount sd card in cwm recovery
(4) clear caches
(5) changed pc's and cables (all worked before)
(6) reinstalled usb drivers on pc (worked before, didn't expect it to help since issue is at phone end)
As you can see, I'm running out of sticks to poke the horse with. Does anyone have any ideas?
Update: new kernel didn't help, either
Update2:
(a) Can't do a restore via odin, which won't detect the phone.
(b) Updated my adb (which I don't use much). adb devices command will not detect the phone via usb.
(c) Installed adbWireless which allowed me to push a stock nandroid backup to the phone. Restored that, usb is still dead.
(d) Restored back to my superdark rom, usb is still dead.
Head scratch: I'd blame hardware except that it seems to be between the settings and execution. If it was purely hardware, I'd expect to see the usual usb notifications. Regardless, it looks like I'll have to revert back to stock and let Verizon figure it out.
Update3:
(a) switched to the new AOSP rom. Nice, but no usb.
(b) switched back to superdark since I like my speakerphone and the AOSP seems to be on hold. Still no usb.
Resolution:
My apologies for not posting a resolution. My bad. After the first few days the post kind of fell off the radar and I stopped checking.
Short version...dirty usb port.
Details...after a week or so, I saw the usb icon flash in the notification bar for a few seconds when I plugged it in for a recharge. Hadn't seen that in a week, hope springs eternal!
A thorough cleaning of the usb port using a paper swab dampened with alcohol restored usb functionality. Not much dirt came out on the paper, but it must have been enough to probably bridge the contacts somehow.
At present the phone is fully functional. The original Verizon cable seems to be a little wonky. I have an aftermarket cable that works fine. It may be that the aftermarket cable did some physical harm to the contacts in the port, or the original cable is going bad (I had something very similar happen on my Omnia). Not sure.
I now use the original verizon cable only for charging at work and use the aftermarket cable for usb connecting at home.
Bottom line...if your usb goes dead as described in the op, carefully clean the port.
My thanks to all who responded...

Download screen shouldn't have harmed you.
You probably are well aware of this, but sometimes it's the simplest solution: Is your usb cable unplugged when you are trying to turn on USB debugging? It will not let you if you are plugged into a pc or mounted for some other reason. Make sure your file manager and any other rogue app is closed. Again, it does sound like you have tried all of this, just giving my best shot ar an answer.
Other then that... Has anyone else had this problem? I haven't seen it in this forum before.
The most general solution to any issue on these fascinates is to undo whatever you did to break it, it's just difficult sometimes to isolate what that event was.
Swyped w/ XDA App. When in doubt, mumble.

Thanks for the reply.
USB is unplugged when turning on debugging. I've also tried turning the phone on with usb plugged in.
The last thing I had done (before accidently activating the download screen) was to install SiMi Folder Widget. Needless to say, it went away with the rom restore.
Also used ATK to kill running processes before turning on usb debugging. Also verified that I still have root.
I've buggered the phone up before but have always been able to figure out a way back (with help from forum searches). This one's got me stuck.
Tonight I'll try to figure out if it can be odin'd back to stock and rebuild from there.
Again, thanks. All suggestions/advice are appreciated.

See op for steps taken to (unsuccessfully) solve this.
Can anyone advise how I can flash back to stock DI01 without using odin, since it won't detect the phone? I can push files to the phone via adbWireless but that's about it.
thanx in advance...

I dont know if you fixed it or not, but here is a stupid question. Are you using the cable that came with your phone? I have several cables that will only charge my phone and only the stock one enables data transfer. Hope this helps. Good luck

This may be my problem! I'm having the same similar effects. Although mine randomly shows the symbol but also says my usb is connected when it does. I've been trying to solve this for 2 weeks now! I hope this is the solution.

common problem
This must be a common problem because I've had the same issue. switched cables and viola, all good.

My exact problem solved:
USB debugging activated on phone but computer did not detect it at all, nothing what so ever. Not even on dial-up mode, or download-Odin (yellow triangle).
Drivers installed (Fascinated and Nexus for the hell of it).
Tried to ADB my into it both from windows 7 and MAC OS-X.
Hell I even tried a different USB cord.
I would get the USB debug icon in the status bar only when on windows7 machine.
I cleaned the phones USB port with the alcohol damped paper towel/tooth pick and the **** worked, first time.
Man I gotta thanks God for this site. I been ****ing with for 2 days.
Then this lil SOB acted as if nothing ever happen. I wanted to beat the hell out the lil ****er. But we are back friends now.
Thanks dude. This **** needs publicized more. I went through a few links before I found this.
I would and tell people to use something non-metallic and removed the battery beforehand. I did just to be safe.

[Q] Connecting to PC with CM7 -- no communication

Hey y'all, appreciate the help in advance.
I have been running CM7 on an SD card for the Nook Color. I like it, and haven't had many problems at all. However, one thing that has been buggy is connecting to a PC.
At first, I could connect sometimes, and see both the internal device memory and the SD card. Then it seemed sort of hit and miss.
Now, I can't connect to my PC at all. I rebooted back into the stock Barnes and Noble system, but my PC won't recognize that either.
I tried a different PC, and two "drives" showed up, but when I tried to look at them, the computer asked me to insert a device. In other words, I still couldn't access either the SD or the emmc.
I see that in Cm7 I have some sort of "debug" or "USB" mode. But when I plug in, nothing happens on either the PC or the NC, whether it is in CM7 or the stock OS.
I can't find where to turn "debugging" on in CM7.
I can pull out the micro SD and the computer will read it -- but only the boot sector, not the part where I keep all my books.
Any help is DEEPLY appreciated. Thanks.
Also (unrelated) does anyone know if ICS CM9 has netflix working yet?
THANKS,
RevTom

USB debugging is under settings, applications, development, Android debugging (or USB debugging under older roms). To turn on USB mass storage, after plugging in, swipe up notification area and choose to turn on storage. It is not automatic on cm7 like it was on stock.
No, Netflix still not working on CM9.

Hmmm. I had it on already, but no notification pops up when I plug into the computer via usb. I also have the "debugging notify" option selected. I did think I had it on, since it *used* to work.
ON the PC I get a "USB device not recognized" message. ON the NC itself, I get no message at all. It behaves as if it is not plugged in -- no notifications, nada.
Tried plugging into my wife's mac also, to no effect.
When I go back to Nook Stock OS, I no longer get the little black box that tells me I'm in usb connect mode. In the stock OS, it also behaves as if I'm not even plugged in, and I get the exact same message from the PC.
Could it possibly be that my cord has gone bad? I've done a little research, and I know some stock Nook users have had trouble with cords. Mine is almost two years old, but I haven't abused it. It still seems to work fine for charging.
Very frustrating....

It could be, but the fact that your nook shows USB debugging notification makes me wonder. But the fact that you are having trouble with both roms suggests that it is the cable.

To clarify: debugging, and debugging notification are ON, but when I plug in, there is NO notification.
However, like you, the fact that the stock ROM won't connect either makes me wonder.
An SD card root like I've done wouldn't mess with the stock ROM on the emmc, would it? Would it change the hardware or firmware to cause this problem?

No, it does nothing to stock. You have a bad cable. The 'data' lines are broken somewhere along the cable or fittings. You can still charge with it because the power and ground lines are intact.
Edit: If you don't want to spend a lot of money getting a new nook cable, you can use your defective cable for charging and a standard micro USB cable for data transfer. Those work fine for hooking to PC as long as you don't try to charge with them.

Thanks,
I took it to a B&N store. I removed the SD card because I felt like a boot legger -- but anyway, they tried a new cable and it worked with Stock, so it WAS the cable.
Thanks!

You may get ADB and/or Storage working if you (re)install the drivers:
scour through Device Manager:
View menu... check show hidden devices
Look for any of the following sections and remove tem:
"Android Phone"
"Android ADB Interface"
"Android Composite ADB Interface"
"Android Bootloader Interface"
Additionally... in USB controllers... you want to check each device listed ... (Properties / Details / Hardware IDs) and remove any that begin with any of the followng:
USB\VID_0451
USB\VID_18D1
USB\VID_2080
USB\VID_22B8
USB\VID_0BB4
USB\VID_0BDA
Then re-install the drivers.

Thanks Dizzy. It was just the cord. I reloaded CM7 (i.e. put the sd card back in) and all my computers recognize it again, and I get the USB/debug notification on the NC again. As computerist diagnosed, I must have broken the internal data carrying cables without hurting the power connections. I did some research and a LOT of people have had issues with NC cables. Mine lasted 18 months, and I did not abuse it, so it isn't a great system. Hopefully this next one will last longer.

[Q] My Nexus 4 USB MTP Not Working Anymore

Hi guys. I ran in to an issue I've never experience before, for some reason my Nexus 4 is no longer recognized when plugging in a USB cord. It was working fine like 2 weeks ago and I made no changes since then. Everything is pure stock with unlocked bootloader, no root and I'm on Lollipop which was updated via OTA with no issues plus I did a factory reset right after just to make sure. I tried everything that has been mentioned in other threads, made sure MTP was checked, USB debugging off or on, updated drivers on my computer, changed USB cords, rebooted phone, booted in safe mode and here's the thing, it isn't even recognized by my car stereo when it was working fine 2 weeks ago. I already made sure it wasn't the stereo because I plugged in a USB driver and it read it right away. I started to think that maybe the USB port on my phone went bad, but it's charging fine so I'm like clueless to what could be wrong right now. I only have 1 last thing that I could do and that's to do a factory reset, but I'm trying to avoid that so if anyone could help me in anyway I would greatly appreciate it.

Turns out that it is in fact the USB port, I noticed it was pushed back past where it's supposed to be because of an indent or line of where it used to be in the inner opening so I started to wiggle it around with the Xbox One controller USB charger that I have which is newer and grips more when plugging it in and I got a reading finally but it didn't last ?, I think this cable is what pushed it back farther and now I can't get it any closer without causing damage SMH, just when I was starting to like my Nexus 4 all over again. Oh well on to the Nexus 5 then faster than I expected.

Problems with Nexus 6p not mounting to my computer.

First and foremost I already have the drivers installed properly on the computer the OEM cable and a few others to be sure it wasnt a cord or computer issue.. But when i plug the phone into the computer the nexus doesn't show up either as i mass storage device or even in device manager. To see where I'm coming from I bought the nexus online and the seller sold it for parts and said the phone was in alright condition and said that it works in excellent condition before he wiped the phone and that it had no OS and that he didnt know how to fix. So I thought it was just a simple fix and bought it. Lucky the phone came with twrp already so i plugged in the phone and nothing happened, and I tried sideload and also didnt work. like i said before i installed all the drivers and everything so thats not the problem. I tried the Nexus Root Toolkit and didnt work. I even did the OG way by manually using fastboot but the computer didnt detect the phone. The only method i have left to use is the OTG method so i wouldn't need the computer. Has anyone had this problem before? I searched everywhere to see if anyone had this problem but couldn't. But if you guys already made a thread for this specific problem shoe me. Im thinking its a hardware issue something to do with the port

That's a tough one hopefully it reads OTG and you can flash something. I would grab latest udated twrp and flash first in current recovery. A lot of the new stuff requires it.

this happened to me after owning my Nexus 6P for almost a year. When I plugged the phone into my computer's USB port. Windows didn't acknowledge it BUT the phone was charging.
turns out I needed to get my daughterboard/USB port changed. Sent it in to HUAWEI and they did it for free under warranty (I was without a phone for like 8 days).

I am actually starting to have this problem now... I am certain I am well out of warranty. Plus... I don't trust Huawei.
