[Q] Nexus S not appearing in device manager in fastboot - Nexus S Q&A, Help & Troubleshooting

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

Hi stoo
I have a same issue - did you managed to find solution for yours?

easy way to set up fastboot

Any solution
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

[Q] Stuck in bootloader with non-working power and volume buttons

I restored a backup with TWRP and am now stuck booting to the bootloader. To make things worse neither by volume buttons or my power button works so I can't get back to recovery.
The bootloader screen says Fastboot Mode at the top in red letters but I cannot gain usb access to reflash a new rom. Is there something I need to do to enable USB in the bootloader (I have the SDK and drivers installed on my PC already) or could my usb connection also be busted
Type from CMD:

That should get you some info. If it doesn't work, your computer isn't set up properly.

Nothing comes up which makes me think the usb connection is busted as well. I dropped my phone a few weeks ago which ended up breaking my power and volume buttons but now that I think about it I haven't used the usb data connection since then so I wouldn't know if something happened to that too. I can still charge my phone though. adb/fastboot are set up correctly because I've used it from my PC before. When I'm in the bootloader and plug the usb it doesn't show up on my pc so I think the drop broke it too

[Q] Unable to fastboot or recovery mode; just unlocked

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.

[Q] no adb and fastboot access - no root possible?

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!

Screen turns off after entering PIN

Hello guys,
I just replaced screen on my 64GB OPO. Phone was fine before screen broke and I had a PIN lock on it. Now, when I turn on phone, I cannot do anything on my phone besides pulling down notification bar and swipe notifications. If I try to unlock by entering my PIN, screen turns off right after. If I enter wrong PIN, it will say Wrong PIN, but as soon as I enter right PIN, screen turns off.
I'm not sure why this is happening. I decided to boot into recovery and reflash the ROM. I hold Power + Vol Down, but phone starts booting normally, no recovery. Then, I try to go into Fastboot by Power + Vol UP, and phone boots normally, no fastboot. At this point, I cannot access recovery or fastboot. Then, I try ADB on laptop, I get "Unauthorized." I can't authorize ADB RSA dialog on my phone because as I said, when I enter my PIN to unlock my phone, screen turns off. Recovery, Fastboot, and ADB worked perfectly before replacing screen.
Anyone know how to fix this?. Thank you
TL;DR:
Replaced screen. Entering my PIN turns screen off immediately. No recovery, No fastboot, ADB gives "Unauthorized" Error.

You can use this,it does not uses fastboot and instead uses hardware debugging port.
Also using this on Xp system will make it easier to detect the device.

I looked at that tool before I made this thread and in 3rd step, it says to press Power + Vol Up? Doesn't that mean you have to be in fastboot? Anyway, I tried it in Windows 10 and it didn't do anything. My phone gets detected by my laptop and everything. I will try in Windows XP and see if anything changes.

No, power+vol+ is actually done to trigger the qualcomm port,if your device can't boot to fastboot,it means it's actually dead then your pc should be able to detect it as "Qhs_bulk" or "usb qcom diagnostics 9006".
Make sure you install the drivers given in the thread or Qualcomm 2012 drivers.Again this procedure doesn't work on fastboot/adb drivers!
You'll have to disable driver signature check on win8/10,Xp works without any issues.

[Resolved] [HELP] Phone not reacting, power button broken

Hi,
I have a problem with my Motorola Moto G4. I bought it 2 months ago and unfortunately the power button broke and I am therefore not able to turn my phone on/off. That is in general not a problem since the device is still under warranty and I will get the phone repaired. The problem is that I want to backup my data, which I am not able to, before getting the device repaired since the workshop will reset the phone.
I am still able to unlock the phone but no apps or windows can be opened (taping on an app icon does not do anything). Dragging down the notification bar is possible and if connected via USB I can still see the status, unfortunately I am not able to change the setting from charging only to data connection. Since the power button is broken I am not able to reboot the device. I tried to use the adb tools to reboot but the device is not authorized and I would need to change that on the phone which I am not able to. Is there any way to reboot the phone or to access the data.
Any help would be really appreciated.
you might be able to try the commands for adb reboot recovery as the phone is booting up - iv never tried it but adb should be working after the moto splash screen (during the boot animation)
Im not sure if it needs authorisation during that stage but if you cant get into recovery and you cant change the usb connection/authorise adb then I cant see any other way to get the data off

If I would drain the battery to "shut down" the phone, would there be a way to turn the phone on without the power button?

with older samsung devices you could use a usb jig to get into download mode without the power button (its a usb cable with some pins crossed you can buy them for only £1 off amazon/ebay)
even if it did work you would still need the power button to select the option to restart phone so the answer is nothing that I can think of

I found some mechanisms to get the phone turned on and I will try them out. I guess I have nothing to lose.
The interesting thing is that my phone is still receiving messages and news (I see them in the notification bar), so things like that are still working but unfortunately new "widows" can't be opened.
Thank you for your help.
I was able to get the phone rebooted and after the restart everything works as it should.
This is what I did:
Drain the battery (using the flash light), once the battery is flat connect the phone to the PC
Press and hold the volume down button until the Fastboot menu appears
Download ADB tools (the minimal version with adb and fastboot is sufficient)
Install the Motorola driver on the PC (I was not aware that I need this, since connecting the phone without the driver being installed and running adb device results in the device being shown)
run fastboot reboot
