Hi to all i got a Samsung Captivate in Download Mode and I cannot do anything because my pc recognize it as unknown device. I installed and uninstalled drivers from forum and from samsung url but still the same problem. I downloaded AIO pack and installed the drivers but still no luck! I installed KIES but still nothing.... any ideas how to fix and flash my phone again to stock fw????
Thank You in advance
Have you tried multiple ports?
Delete drivers, dl again but don't install. When plug in message for unknown device pops up click it and select option to find drivers. Navigate to the file where dl is
May work

I have android sdk if is the same i dont know!
Sorry typo. Once again long shot but plug phone in click on the unkown device. Navigate to android sdk I think under extras then Google add one there is USB. Click on it then ok. See if it can find drivers that works
Sent from my Captivate using XDA Premium App
not compatible with x64 windows
Make sure you have the most recent USB drivers installed in your sdk. You may need.to enter sdk manager first. I may be wasting your time.

I gave a try to another pc still the same Unknown Device. Is there any way to bring it back to life??????does anybody knows??
Hi folks,
I feel like a noob here.
When I have tried to update the phone the new formware I couldnt get into flashmode. This initially did not worry me as I have seen loads of posts about this and I know how to sort it.
I got home from work and unistalled all android software (Fastbbot, adb, sdk, pccompanion, sues) and reinstalled them. I tried again, no luck.
Now i thought i would try my wifes phone. Its not rooted. It went into flashmode straight away, so now I am ata loss.
Flashtool recognises my phone when turned on, it says all drivers are ok, but i get nothing on my phone when i try to connect it turned off...
Now, if anyone wants to help me and call me a noob please do...but this one has me vexed...
EDIT, Dont shout, I have already asked mods to move this to the Q&A section
Probably too much to say that you already tried a hard shutdown?
Else try a stock ROM/kernel. Maybe something went wrong with your current kernel

Tried it already. 3 vibrations, no luck
Also no output from flashtool?
I noticed once I didn't see led, but it was in flash mode..

you are pressing down not up on volume right mate?

You would get blue led in that case. So would be kinda obvious

Look guys, I can get my wife's phone into flash mode and she has an Xperia T, so it is nothing to do with which button I am pressing. I use the same cable and same usb port...
The last time I tried to get into flashmode or fastboot was before Xmas,
It is definitely to do with my phone..I really can't understand why flashmode is not connecting, in previous experience that has worked in all circumstances, but now nothing... Even though flashtool recognises the phone with the correct drivers when it is turned on...

No nothing, flashtool just acts like nothing has been connected... Pccompanion eventually times out as if nothing had been connected

My last guess is it's something in the Rom. Try flashing a 4.0.4 system.sin via fastboot, and access cwm to do factory reset (btw, you did try a different kernel right? You said you did it but wasn't clear of you meant only hard shutdown or kernel too)
My experience is also that it always works. Haven't encountered something like you have before so only shouting some possibilities.
Do say if you already tried something I say ofc.
Something else you can try is different pc (if you have access to one) Have heard of some cases that that did the trick

Sv: Flashmode advice
I had similar problem with my v some weeks ago, have two thoughts, have you switched between stock and cm kernel? Have you tried another pc?
Sent from my Xperia V using xda premium
Again, thanks for the advice but a couple of things.
I can't change kernel because the phone is not entering fast boot mode
I can't flash a stock ftf because the phone is not entering flash mode
Its not the pc because it works on my wife's Xperia t
I have already done a factory rest.
After work today I am going to try flashing a 303 Ron in recovery and hope I can do an ota update and hope that works...

Have you tried doing adb reboot bootloader to get into fastboot rather than doing it manually on boot? Or does adb not work either?

Hmm, Interesting,

Second time, it briefly entered fastboot (Blue LED) PC started to install S1 boot driver then the phone rebooted and the driver failed to install
Third time, phone went into fastboot and stayed there but no sign of a driver install.....

I cant get into fastboot manually, only by using adb reboot bootloader.
Now the next thing to ask is, well are your volume buttons broke, but no, they work fine to turn the volume up and down with so its not that.
I have just managed to flash a different kernel so will try flash tool again.

Use one cmd/terminal window to adb reboot bootloader, while flashtool is open, has always gone straight to fastboot for me.

Yes, that gets me into fastboot, but i need to get into flashmode to repair the phone.
I am a bit of a nivice at adb
Currently I am charging my phone ready to try a repair. Now I have flashe d another kernel I will give it a go again. If this doesnt work I willflash a stock kernel and try and that...
It's possible to force a full power-off of the phone (not just a three-vibrations one).
I am not keen to post the instructions on the forum, as it isn't the nicest of methods (but it doesn't require you to open the case). PM me if you have no other options (if you can hook onto UART to see what is going wrong, that might be best)

Fastboot -w all
Will wipe data and caches, so should clear what ever is triggering the bypass of flashmode.
If really desperate you can also -w system, but then have no os... Handy if the os is causing the bypass, but not helpful if it's the bootloader..

Install flash image GUI from play store if you are currently able to use the phone. You can flash boot.img using that app and can then boot into recovery to flash the rom. I have had great success with it

Hi,
I am using Desire C for more than a year, and i have been using customs ROMs starting with Nameless. Recently I flashed NOPE Kernel, and installed Simplicity ROM, 4.1.2. After that i am not able to flash the boot image again. It is connecting properly when in connect to the system, but once i get into Bootloader mode, suddenly i get a message "Device not recognized", and i cannot connect anymore. I tried installing and re-installing all kinds of drivers available for Desire C and HTC, but no luck. Can anyone help on this issue... Please.....
Weirdness. What commands did you try? Type adb devices in CMD and if numbers come up then it is connected

When it is in Boot loader mode, I don't get any number, tried adb devices, result was device not found. Once I'm in bootloader, none of the adb commands works. Not even reboot command.

It is supposed to say FASTBOOT USB. From the bootloader screen, select the fastboot option using your volume and power buttons.

Tried re-installing all the drivers... Checked out some forums, and downloaded HTC Drivers, installed, still not working...
When it reboots into BOOTLOADER, it doesn't show FASTBOOT USB, but when move up and down using volume keys, it shows FASTBOOT USB. Not returning anything for FASTBOOT DEVICES. Tried to flash, showing "waiting for device"... and after sometime, got the error "windows did not recognize the usb device"...
I have a flashable boot image zip file for HTC Explorer, tried changing the boot image, and flashed. No error message then, but still shows the old one itself....
So, can anyone help me by creating a flashable boot zip... I really need to change NOPE kernel...

Did You check Your USB cable? It could be that it is failing...
Other than that, connect your phone in fastboot mode, wait until error pops up, then do this:
Start command prompt (as administrator in windows 7, 8...) and type this (followed by enter):
Code:
set devmgr_show_nonpresent_devices=1
and after that line, type this:
Code:
start devmgmt.msc
Now try and find devices with exclamation, there should be your android device. Now right click and uninstall it. Then plug out your phone, and plug it back in. If it doesnt't work after this, I'd say that all you can do then is to reinstall htc drivers.

No Luck... tried re-installing the drivers... changed the cable... even tried a different system... No luck at all... I think I'm gonna be stuck with this itself..... at least until buying a new cell....
Talking about new cell, I am planning for HP Slate Voice Tab 6... Any one, any suggestions on that...
Now the touch buttons are not working properly. They keep playing dead sometimes... I think my cell is coming to EOL... lol...

I rooted my One months ago when I got it, installed viper one, and Ive been loving it.
But I havent been updating it, and my viper one was on version 2.7.
I was going to wipe my phone and install the newest version, but something went wrong with the installation and it wouldn't go through, and it somehow corrupted my CWM.
Now I cannot boot back into recovery, and Im in a bootloop.
I can get into bootloader, but thats about it.
My phone is S-ON, and I can't get my PC to detect it to flash a recovery, or anything else.
Ive updated my HTC drivers, and it doesn't seem to be helping.
Edit: it seems that my PC will detect the phone while it's in bootloop, and will go as far as putting the phone into fastboot.
But once Im in fastboot, it no longer detects my phone, so I cnanot flash a recovery.
When you're in the bootloader with your phone connected. Can you see the driver installed in device manager in windows?

What Windows are you using. Use Windows 7 if you can. Windows 8+ can sometime have problems communicating with HTC drivers..
