So you wiped everything and have no system installed so it won't boot or what? If that's the case you need to install SDK and USB drivers on your comp and flash a a factory image using one of the various toolkits.

Didn't help in my case. I did the backup and wipe/factory reset the phone. Enabled the debugging mode, removed kies and all the drivers, rebooted the phone and the pc, connected the phone to pc and had the same message Any idea where I could got it wrong?
P.S. ANd the phone is now extreeeemly laggy and unresponsive
Well this is brilliant! I have made it even worse. I thought thought, that maybe the kernel is the cause of the issue, downloaded the SGS KErnel flasher and flashed the CF-Root-XW_OXX_JV1-v1.3-BusyBox-1.17.1. After the reboot the phone is stuck at the GalaxyS logo and is not booting. I can get into the recovery and the Download mode but the phone is still not being recognized and when I try now to wipe/data or do a factory reset I get loads of red errors Please tell me that I didn't brick it yet

Do you have a rom on your sd-card? Flash it trough recovery.
Or doesn't recovery even recognize your sd-card?

It was in the previous kernel. But in the last one I've flashed there is no restore/backup functionality, although the backup might be actually be on the sd card

Well, there seems to be only a one solution.
You have to uninstall the phones drivers, and install them again.
Then plug your to your computer in download mode and it'll install rest of the drivers.
Then Odin should be able to recognize your phone and your good to flash stock.
But you really, really have to uninstall the drivers
Well I did it before. I uninstalled all related to samsung from the add/remove programs. Rebooted the pc and still getting this error. In the properties of the device in the device manager I have "unknown device". I don't have any drivers on the pc as far as I see. I install the drivers from here. Connect the device again and get the same error

Hmm.. I did change the computer.. Maybe you should put the drivers on a flash drive and go to your friends computer to flash.
The thing is that he does not have the drivers installed before either.
Don't know why it worked for me but... it worked.
I am going to try the last thing - I have a System backup from the time I definitely didn't have them on the PC and see if this helps....
Nope.... Didn't help.... I am completely desperate. Maybe anyone would have another magical solution?
Guys! ANy idea? Plzzzzz. I'd do anything to get it back to life
Me too i get "unknown device" when attached with usb in download mode...ive been trying to get it back workin for a week now...tried everything...which means i can't flash it to gingerbread
Anyone got any ideas ?
I have tried different PC's and it's the same. Is there maybe a way to reset the device somehow?

Hi!
I have a similar problem.
For few days, I cannot connect my SGS to my Notebook.
I have windows 7 x64 installed, and it has never had any problems with connections.
Now, I don't know why, but I cannot connect it.
I tried to connect it to another computer, which has windows 7 x86.
And it was succesfull!
Now, it seems, that I don't have a hardware issue, but I cannot imagne, how I could solve this problem.
I already tried these:
- remove drivers/programs
- tried other USB slots
- downloaded newer USB driver for x64
- removed USB drivers (all of them)
- unplugged my notebook for over 5 minutes (also removed the battery)
Every time I plug my SGS to my PC only this message appears:
"unknown device" - or something similar, because I have a hungarian windows 7.
Sorry about my english.
Has anyone any idea?
Thx for advance

[Q] One has no SD Card - no mount in recovery - no rom installed

ok, so my phone is screwed.
Been trying touse this thread to recover it - http://forum.xda-developers.com/show....php?t=2325853
I have no SD Card, I can not mount SD Card in Recovery.
I have from what I can tell installed the Android SDK and when doing 'adb devices' I get 'error device not found'.
I have uninstalled and reinstalled HTC drivers and sync, does not recognise my phone. Device manager shows my One but can not find any drivers for it.
I have tried the All In One Tool to sideload, does not work, does not reboot to bootloader etc due to drivers not working.
Basically my phone is dead as, what can I do? Take it to HTC, how much would it cost to fix?
Cheers
EDIT: If i reboot system from Recovery it tells me it does not have root, do i want to root it? I say yes and it reboots to splash screen, nothing else
What operating system are you running?
If you're using Windows 8 search for the thread with the windows 8 drivers.
I accidently formatted my SD card while I had no rom installed. It took a while but eventually ADB picked it up and I was able to push the rom to my device using ADB push (I was also getting the "No devices found" message). This was before I found the windows 8 driver thread, it just randomly started working after many resets of both my phone and computer.
What recovery are you using? Do you happen to have a flash drive and a usb otg cable? This is an other option.

that is easy dont panic
1- if the drivers is not installed properly you cant do anything from PC and send it to the device
if you are using Windows 8.1 there is NO drivers for it,
if its Windows 8 there is NO official driver yet but you can install Windows 7 drivers
if its Windows 7 or earlier make sure its installed correctly if you dont know reply to my comment i will tell you anything you want
2- it happned to me too No Root and NO Rom installed, i simply copied the ROM to a USB Stick and using a USB OTG cable ($1) i plugged the cable to the phone and mounted the cable and then installing it from there,
tell me more about what you have and i will help you
Spent a few hours last night working on this with the help of Matt from here
I have CWM Touch (latest) and he was able to fix the driver issue, and we got sideloading working.
Will push the rom to phone, install, start roms splash screen but go no further. Still no SD Card or missing the mount points to show SD Card.
Attempted to S-Off, failed, unsure if CID 11111111 was successful. (Not CID11111111, was HTC_039 now VODAP21 or similar)
I has told/read an article that if you flash a differnt base (eg ICS to JB) that it will replace a script that handles/writes the mount points..
That worth a try but I believe all roms are JB. Any idea of any ICS roms for the One??
I can not find a RUU for 1.29.980.2 to try, only Nandroid Backups that I can not use as no SD..
EDIT: what does a flashing red led mean too? Cheers

PC won't recognize HTC One after installing KitKat 4.4 Sinless ROM 5.1.1

Hey guys, flashed Sinless 5.1.1 last night and ever since installing this particular ROM I'm unable to access my phone's folders via MTP or anything. I've tried re-installing drivers on my PC, rebooting phone and PC several times, trying to access my phone in ADB and fastboot... I can't even push or sideload a new ROM so I really don't know what to do!
Anyone got any idea what to try next and/or how to solve this?
Did you enable Developers options USB debugging?
If not go to about phone and click on Build number a
bunch of times. If that doesn't work install latest HTC
drivers.

I'm actually running that exact ROM and my phone is seen on both my Mac and Windows 7.
Did you try a different USB port? Does a message pop up on your phone asking to trust your
computer? My computer wouldn't see my phone until I accepted that pop up.
If you've tried all that then give a little more info on your PC so we can diagnose it.

I never saw any message pop up. I've tried 4 different USB 2.0 ports. My USB 3.0 ports aren't usable.
I am runnings Windows 7 x64 Ultimate with latest HTC drivers installed.

Kinda stumped then! Only thing I can think is that you don't have the very latest drivers.
Can you ADB and see the phone? Check the following thread on how to do this.
(Sorry if you already know how)
http://forum.xda-developers.com/showthread.php?t=2365506
If I do "adb devices", nothing shows up. Simple commands like "adb reboot" respond with "error: device not found".
I've just flashed ARHD 31.6 (Android 4.3) and re-installed drivers and my phone still isn't recognisable. I'm lost!
Okay, big trouble now!! I just read elsewhere that it could be an internal storage corruption problem, so without thinking I formatted internal storage along with data and system in recovery and attempted to ADB sideload a new ROM and was going to start over. Stupid idea! ADB still isn't working so now I can't even sideload or push a ROM. All I have to work with now is fastboot and recovery, and my PC isn't recognizing either of them. Any ideas?
YOU AREN'T GOING TO BELIEVE THIS!!!
Girlfriend stayed over the weekend and happened to swap our USB cables over. She left and took my OTG cable and left me with her identical looking USB charge only cable.
Just tried my mother's Nokia cable and voila! Installing device drivers.
Now to sideload a ROM and start from scratch -.-
I know this thread is old but if someone stumbles upon it this is what I did.
New USB worked.
***While using the USB cord that wouldn't connect like it usually does, I re-installed HTC Sync Manager and it immediately recognized it.

Disconnected the phone from the computer then reboot the computer. Does the phone now show up in Device Manager? If not change USB cables and try again. If the computer recognizes the phone, then you can move files to the phone.
Thanks

To solve the no OS part, just flash a guru reset or a nandroid backup for your device.

I've never really experienced connecting my device to the PC won't work. Sorry.
Just buy an OTG cable and put the ROM in a USB and plug it to the OTG cable so you will be able to install the ROM. If you successfully installed the ROM try connecting your device to the PC again.

If you are still connected to the computer when you are in Recovery, Device Manager will disconnect when the phone boots in bootloader or recovery.

Nexus 6 wont detect MTP USB but charges fine

Anyone with the same issue ? I am stuck at the bootloader since I wiped out my system image I can get to the recovery but I don't have a way to transfer new ROM since phone wont detect USB (MTP).
I didn't have any image backed to restore to. Tried OTG cable/USB nothing worked
What are my options ?

Hi... Is data mounted and MTP enabled in TWRP?
Is your phone detected while in bootloader?
Try: fastboot devices
If phone is recognized, download stock firmware of your choice and flash it...

What operating system is installed on your computer?
Did you already install adb/fastboot drivers?
In device manager, while being in bootloader, is your phone detected when you plug your USB cable?
Did you try different cables, USB ports?

I tried different cables/PCs nothing worked. I think my phone USB port is defected but what confuses me more is that it can be charged just fine but no USB connectivity
It is still under warranty but not sure if it will be honored since I have the bootloader unlocked.

Nothing like said it is dead. I have another nexus 6 can connect easily to the PC I am pretty sure it is a phone issue.
Well, if you're 100℅ sure the USB port is damaged, there's nothing else than a repair that could bring your phone back to life... Good luck..!

Might be a driver problem.
Connect it your windows pc and check the Device Manager if it is detected as "Android" device. If so uninstall it and disconnect and reconnect it to the pc. Let windows install the MTP drivers.
