I'm attempting to flash clockwork recovery and can't get the phone to respond to fastboot devices when in fastboot mode. I've tried everything I can find with regards to the drivers (pdanet, usbdeview, etc) and I can get google's and pdanet's drivers working fine with the phone booted normally (responds to adb devices). The problem seems to be that windows appears not to even notice that the phone is plugged in in fastboot mode and does not appear in the device manager, making the manual installation of drivers an impossibility.
Anyone know how to fix this?

When I first set up ADB and Fastboot on my pc, I was getting a response when writing 'adb devices' in the console. However, 'fastboot devices' returned absolutely nothing.
Solution (with phone connected to pc and usb debugging cheched):
1-shut down the phone
2-press and hold Volume Up key + Power
3-once in bootloader interface, in the pc command prompt, type 'fastboot devices'.
Voila!
By the way, don't mount the phone as usb storage device.
Thanks for the responses guys but yes, USB debugging is enabled and yes, I've used that way to get to fastboot mode as well as adb reboot bootloader

easy way to set up fastboot

Have the same problem: locked bootloader, not rooted 4.1.2. In ADB everything is ok, drivers ok (in device manager), can get it through "adb devices". But when I boot in fastboot (adb reboot bootloader), I hear the ti-da windows sound (usb unpluged - from adb session), but no ta-di when the phone re-boot in fastboot. No exclamation mark in device manager, nothing. The USB receive nothing when in fastboot. Is it possible that the fastboot image is corrupted? Can I reflash it? Or any other advice?
Thanks
EDIT - SOLVED - at least this step
The problem was the famous "broken power button"! I knew that I had problems with the power button (didn't work - that's why I try to flash a rom (4.2.1 or customized) with sleep tile in notification area).
I thought that the button is all the time OFF and don't switch to ON, but I finally understood that when when I boot in fastmode it freeze before installing device on the PC (I also had no volume up / down navigation in fastboot, a sign that it was frozen). So I ended to consider that the power button was permanently in ON position. I opened my phone and I measure the impedance on the power button. I had ~ 4ohms in off position of the button and 1.8 ohms (cheap multimetter.... probably should be almost 0) in on position. I measured also on volume switch where I had ~ infinite on off position, so I concluded that the button if blocked. I tried to see if I can resurrect it but no choice, so I took it off (unsoldered). I put the battery and the USB cable and boot it. From ADB I reboot it in fastboot and voila! The device popped in device manager! One problem solved! BUT...
I tried to use the Nexus Root Toolkit and it boots in fastmode and try to unlock the bootloader, but it asked me on phone screen if I agree for unlocking. I was able to use the volume to select Yes but I couldn't choose it with power! I had no option but to take the battery off. Starting from that point it was almost impossible to power it again. When I plugged the USB it shown the battery icon (charging). I tried every trick that I found on web, but nothing worked (even to fast plug / unplug many times the USB to overcharge it, but nothing). I was able only by pressing on the middle of volume (so Up and DOWN in the same time) and plus the USB to get to the screen of unlocking bootloader, but without the options YES/NO on the screen. Seems that it saves this state between boots, but why no option? Finally I was unable to boot at all, and it is like totally bricked
I thought that the power button is a simple switch ON / OFF, so I soldered 2 wires and I tried to touch them (short circuit) to simulate the ON, but nothing happened. Is it the button more complex that a simple switch? no ideea...
So now have a better phone than before (at least theoretically it should be able to fastboot), but it values zero because I can't power it on....
OK So I am in the exact same situation.
Nexus S, Broken power button, adb can see the device, fastboot cannot. fastboot cannot be navigated with the volume keys.
I also want to put an other rom onto it, but firstly I want to put TWRP recovery on it, as it supports touch, CW needs the power
button which like mentioned does not work.
I would rather not unsolder my power button to get into fastboot, any suggestions on how that might still be achieved?
thx

Yes, it should have been better for me to have also a possibility to enter in fastboot with the power button blocked in ON position, but I didn't find. And now I know no way how to power it up...
fastboot drivers
http://www.samsung.com/us/support/owners/product/GT-I9020PWAATT#
has anybody considered using this executable from samsung ..
from what i understood when installing it ,it only unzips the contents at programfiles/Samsung/drivers
then you can check this thread to install them spesifically http://forum.xda-developers.com/showthread.php?t=1901617
..In short.
Go to
"Device Manager"
find
"Android 1.0" or something like that (i had my device in fastboot/bootloader mode, dont know if it was necessary)
install drivers from the drivers directory and install
P.S. Mine is an ordinary 9023nexus s (slcd) though
be a bit more careful with nexus s4g
Hi. I've recently bought my TF700 and upgraded to JRO03C.US_epad-10.4.4.25-20121228 (JB 4.1.1). Now I want to root my device, so I first unlocked the bootloader using the ASUS unlocker. That went fine, since it says "the device is unlocked" in the boot sequence. The device boots and works properly.
Now I wanted to get to the stock recovery mode for a backup, but it fails miserably. I get to the four icon menu (RCK, Android, USB, Wipe) and select RCK. Then an android icon with a blue rotating icosahedron in its chest apears for a couple of seconds and then a "dead" android with it's cover opened and a "!" enclosed in a red triangle. After a couple of minutes, the device reboots normally (I can force that by pressing down the power button for 10 seconds).
I tried to get to fastboot by choosing the USB icon, but it does nothing (just freezes in the four icon screen and stops responding to any other buttons); the PC doesn't see an USB device of any kind. I tried connecting the USB cable both before and after selecting the USB icon with no difference. I'm sure I have at least some good drivers because I can use adb with my device when the OS is running.
I'm new to this device, so I may be doing something wrong. Any suggestions? Thanks in advance.
The stock recovery can only apply stock updates, you cannot use it for making backups.
Fastboot mode should display some message similar to "fastboot protocol enabled", the rest appears to be driver problem on your PC. Fastboot mode uses a different USB ID, so having ADB working does not mean that also Fastboot will work.

Thank you, _that. Whatever drivers it might need, I cannot install them because no USB device of any kind appears in my computer besides my keyboard. I think I should be getting "Starting Fastboot USB download protocol" or something. How can I get fastboot to work?
Sorry, it seems it was a USB port problem! I changed the port and the fastboot device is now available in my PC. Fastboot is now able to send commands like 'reboot' to my device.
Thanks for your clarification about the stock recovery mode, _that.
I have a S2 with a broken screen that had stock firmware installed (I don't remember which). I'm trying to gain access to the device to see if I can repurpose it for something else.
I tried following the guide here (http://forum.xda-developers.com/showthread.php?t=2786395)
I installed the adb/fastboot from here (http://forum.xda-developers.com/showthread.php?t=2786395)
I put the device in Download mode by pressing Vol UP/Vol DOWN and then plugging in the USB cable to a WinXP machine. On ODIN I can see COM6 light up, but if I run adb devices nothing shows up.
I think I'm missing a step somewhere. I think I need to get into recovery mode and not download mode, but I'm not able to do so without seeing the screen. I'm following what it says here (http://forum.xda-developers.com/showthread.php?t=1409769) but when trying to get into recovery mode it sounds like the phone just boots up instead.
Any suggestions? I think the goal is somehow enable usb debugging. I'm okay with losing the data on the device.
Hello everyone!
I'm trying to root my Shield K1 (Android 6.0) since hours, without success because:
I have no acces via adb. Im using the latest adb and also the right drivers (see picture) but I alwas get the message "unauthorized" in adb.
I can't boot my tablet into fastboot mode. When I press the power button + volume up to come into the menu and I select fastboot protocol, the tablet just starts again into the same menu - so i don't get into the fastboot mode. Pressing the powerbutton + volume down don't works either.
I have tried already almost everything: uninstallig drivers/reinstalling it, factory reset on my K1,...
So how I can root my phone without adb or fastboot? Can anyone help?
Even the recovery mode is broken I think, after booting into it, the green android with an red triangle is shown.
Is there something wrong with my K1?
PS: In the menu, which is shown after pressing power + volume up, is standing:
[nvtboot] (version UNDEF_BUILD]
[bootloader] (version UNDEF_BUILD]
Device - locked
You need to enable USB debugging in the developer settings and then allow debugging access from your computer by accepting a popup on your tablet.
Yes, I know this and I did this of course. But there never poped up something on my tablet.
So I also resetted the debugging setting, wiped the tablet, but nothing helped.
1. Sometimes the micro USB cable you use can be bad so I would suggest trying a different cable (especially since you have a K1 which doesn't come with a charger or cable).
2. Fastboot mode is that screen with the menu, that's why "fastboot protocol" just takes you back to the same screen. Also, recovery mode on the stock tablet just shows the android icon and triangle, so your recovery mode is fine.
I would suggest booting the tablet into android (so not the fast boot or recovery mode) and connect it to the windows PC using different cables until the authorisation pop up come up.
I am having the same issues as the OP, the only difference is my bootloader says "unlocked."
I was able to get authorization from the computer, no issues there, however fastboot will not find the device and neither will adb when at the "fastboot mode."
I'm trying to get fastboot so I can flash a recovery, but no luck to this point.
Anyone have any ideas or suggestions?

Thanks so much mate! :good: That's the sentence, that helped me. I didn't know this menu is already the fastboot mode. So if one know this it's quite easy to proceed.
Problem solved - tablet already rooted
The adb access is still "unauthorized" but doesn't matter anymore.
No problem, glad you you got it sorted.
It's odd your ADB access is still unauthorised, but at least it still works.

Just as an FYI....I got mine working. Needed to reinstall the nvidia drivers... Got authorization, etc... so assumed working and as we all know assuming is bad!

Heya folks,
I have just attempted my first time flashing TWRP on my TP-Link Neffos X-1 following this guide: https://rootmygalaxy.net/twrp-root-...nd_Install_TWRP_Recovery_On_TP-Link_Neffos_X1.
Its looking kinda grim. It starts with the orange state Message and that the device will boot in 5 seconds, however after that it starts with an infinite bootloop. I also cannot access the Recovery (vol up + power), for it simply doesnt work anymore after the guide. When I plug it into my pc, it will automatically start with the bootloop (I can shut the phone off with vol down + power).
Attempting to get into fastboot mode over ADB (adb reboot bootloader), returns with the message error: device '(null)' not found. I think that is due to it not being recognized in the device manager(it doesnt show my phone anymore but unknown device). I tried to install the phone driver for the uknown device, however that keeps failing. I think its due to the phone permanently connecting and reconnecting to the pc.
So I'm wondering of what to do. I guess the biggest issue is that the drivers are not recognized, but as long as the phone keeps on restarting every couple of seconds i doubt i can properly install the driver. You guys got any ideas?
My guess is you haven't installed on Windows PC the appropriate Android USB Driver matching the device
I mean the appropriate USB driver had to be there for me to flash it with the TWRP in the first place, right?
Think I clearly said that the additionally required USB-driver has to be installed on Windows PC.
I have this one installed https://rootmydevice.com/download-neffos-usb-drivers/, is this the additionally required usb driver?
So far, despite what driver I pick for the device, it shows the code 10, device couldnt be started - probably because it never gets past the starting screen but keeps rebooting

Try this TWRP file: TWRP_3.2.3_NeffosX1_TP902A_by_kiruha_21.img
The thing is, I cannot flash anything due to my phone constantly rebooting while inserted in the pc usb-slot. Neither ADB nor my device manager recognize the device and as mentioned before, I cannot install any drivers

Some MTK devices has this: Press both VOL+ & Power buttons. Only remove 2 buttons when you see Bootloader mode (recovery; fastboot; reboot system) or directly in the Recovery mode. Now you can use fastboot.
With the SPFT you can use same tip above. In the SPFT choose DOWNLOAD and plug USB device. Process to flash stock ROM or stock recovery.img & boot.img start.
If not start pugging USB: choose DOWNLOAD - press VOL- and plug USV device. You can try with buttons like only VOL- or VOL+ or combo buttons VOL+&VOL- or VOL-&VOL+ or other button combination.
You can try FIRMWARE UPGRADE too.
That's depend about LOCKED or Unlocked bootloader process that you made before actions!
If you unlocked bootloader so only need patience. If not so that's no good.
