[Q] Nexus S not appearing in device manager in fastboot

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

How do I fix my OnePlus One’s bootloop?

Greetings of the day,
Hello everyone, I'm having a oneplus one 64GB phone that is not getting start, everytime i connect it with the charger it goes into a bootloop. Yes the phone was rooted and I was using a custom ROM with the default kernel. The issue started when I tried to reset the phone to battery settings. I think I somehow messed the kernel and now it is stuck in bootloop. The problem is that I can't connect it to my computer or put it in debug mode as it just restarts again. Any idea how to actually boot it so I can install the kernel and ROM again?

No, My phone is not getting on but whenever i am connecting it with my charger the phones goes in the Bootloop, and when i am connecting it to My PC while pressing Volume Up + Power Button Pc shows that the Unrecognized devices has been connected.
And i think phone is Hard Bricked. I have tried ADB software and one plus 1 drivers manually but it didn't worked too. I have tried minimal ADB too but it also didn't work.
Kindly let me know about it.

Volume UP + Power should boot in fastboot mode. Volume Down + Power should boot into recovery. First, try to boot recovery.

I have tried both, but nothing happens with it, Volume UP + Power shows the unrecognizable device is connected and Volume Down + Power does nothing it continues with bootloop .

Have you got Developer Options enabled?
Goto About Phone & Tap Build Number until Developer Options is activated. Goto Developer Options> Advanced Restart & enable the switch.
Press power button->Restart->Recovery.
It will now boot into Recovery.
Also have you tried keeping hold of power button whilst it bootloops. Keep holding the power button until it powers off. Then press Volume Down & Power Button to power back up (you might see a slight flicker onscreen that means it should go into Recovery mode). Keep hold of these buttons until you gain Access to Recovery Mode.
This will allow you to Recover or flash a different ROM.
If you're having issues connecting to a computer (Windows) try downloading Windows Media Center for your version of Windows. This will install media drivers to recognize your phone.. If all went well you will get the pop up with A0001 (Codename of OnePlus One). From there you should be able to enter fastboot mode through ADB.
If this doesn't help you, I'm sure that someone else will untangle the puzzle to get your device in good working order buddy. Good Luck.

Screen went black

Hi Everyone,
I bought the Honor View 10 and it was delivered to me on 16.08.18. On 17.08.18 all of a sudden while using the phone, the screen went black. The phone is working though as I called from another number and it was ringing. The screen lights up but it is completely black. Since the seller has a replacement policy, I have already raised a complaint and the phone will be replaced. The issue I have is, all my data is on the phone and I am unable to wipe it. I can't do it via adb as it needs to have the USB debugging option enabled on the phone, which I can't enable now. One method I tried was tying to boot into recovery and assuming that I am pressing the correct buttons and wipe it from there. But this is very hard and I am not sure if I achieved anything or not.
This is what I did:-
1. Since the phone is on and currently stuck on lock screen, I need to enter the pin which I can't. So, I keep on pressing the power button until it reboots.
2. Then I press the volume up button and here I think I am booting into recovery. I think I was in recovery because my phone was connected to my pc and it stopped recognizing it. After this I did some button pressings and not sure if anything happened.
If anyone has a method which I can use to wipe my phone, please share. Thanks in advance.

Thanks for the link. I tried it, but since the location on the device was turned off, it is unable to connect to the phone. Here is what more I tried so far:-
I was able to boot into fastboot mode. But none of the commands worked. "fastboot -w", " fastboot erase userdata", "fastboot reboot recovery". My pc is reading the device because when I type " fastboot devices", my device is listed. And the other command that is working is "fastboot reboot".

Another thing you can try, if WiFi is ON on your device, is try to install app to mirror the screen of the phone to your PC, you can do this via PC, open Chrome, log in with same phone's user, get in Play Store and install the app
Sorry but right now I don't remember a good one, but if you search, sure you'll find a good one

Yes location is off on my phone .. I tried that option though but couldn't locate the erase option there .. these were the options:-
1. Ring or Locate
2. Check recent security events for suspicious activity
3. Try calling your phone
4. Sign out on your phone
5. Reach out to your carrier
6. Learn how to take extra steps next time
I tried searching for a mirror app as well. But all the apps I found needed to be opened once on the phone. So, got stuck in that step.
The new replacement phone was ordered today and it might get delivered by Friday. I think I'll visit the service center once before the new phone arrives and this one gets picked up. I though don't think they'll be to erase my phone without replacing the screen. But still I'll give it a shot. Apart from that, if the batter dies and the phone turns off, I'll then try to boot into recovery and wipe from there. Do you know any button combinations which can be used to turn off the phone?

Stuck at entering fastboot mode

How can I get my Galaxy Note 20 Ultra out of stuck at 'entering fastboot mode'?

Hold down power and volume down until it reboots back to recovery. I got stuck there last week and that's what worked for me.

Is this problem solved? I cannot boot into bootloader mode, thanks!

Switch off the device. Then hold volume up and down buttons and insert the USB cable plugged to PC. You will get to download/odin mode

Download mode is different from fatboot mode, I can enter, and works ok download mode. However, fastboot does not, it gets stuck in entering fastboot mode and no fastboot command works

I got same issue here, I've tried rooting via TWRP and after data wipe and "reboot to recovery" it got stuck in same thing and doesn't move at all, if I hold power and vol down it just boots the device which i dont want since i need to flash magisk as a last step. if anyone encountered this or knows how to fix it i'd be helpful

I'm not rooted but I've had past Samsung devices that I was able to root and if I'm not mistaken Samsung phones aren't able to boot into fastboot mode because Samsung removed the ability to. You can run commands via ADB mode but I think that's about it

it gets stuck into fastboot entering if i try to do it the old fashion way .. please help

Guys, turn off the phone, press volume up and volume down together, and plug the usb cable while pressing volume up and down, and wait until the phone enter in downloading mode. This work for me.

Since we can"t enter into fastboot mode is it possible to flash boot.img with adb commands?

I m having the same problem with a21s(a217f). I can t enter download mode using key combinations and the other way launching it from recovery doesn t work, it stays stuck at,, entering fastboot mode,,
The ROM is already bricked, it says in recovery when i try to factory reset the following error:,, can t mount. /system (structure needs cleaning)
Even with,, apply up. with adb,, doesn t work, it just doesn t get detected on my computer when i checked with adb tools.
! The only thing that works is that I can access my sd card and apply a update from sd card but I don t know where to get the update file. (I ll edit if it works to flash stock rom from,, apply update from sd card,, )
Anybody got some ideas or should i burn my motherboard and replace it?
sorry for bad english

Honestly plug device into PC.
Power off device
hold all 3 side buttons. Volume up and down and power/bixby.
Should usually work.
After in fast boot you must press a button Volume button to find via odin.

I already did that, unplugged the battery, reconnected it after 1min, connected my phone to the computer and pressed all 3 side buttons, still doesn t work. I guess the download mode is deleted or something..

Volume up & down, no side key, then connect to PC. Works for me. Connect to PC first does not work for me.

It wouldn't be deleted as it's a safety protocol if the device has a bad update and freaks out.
Maybe try to person above method.
Normally I can enter download mode with any of these methods if you cannot I'd suggest trying to get the device replaced due to software malfunction

Samsung phones use a tool called Odin to flash firmware. If you're flashing custom firmware firmware you'll need to have your bootloader unlocked.

I got mine into download mode just now. It's a Galaxy A13 .. Like stated above, try to hold all three buttons down and connect to USB. I had to let go before it showed the battery charge icon. From off. If not from off try from charging. I think that's what I did just now. Plug the usb -> let it show the charging icon (from powered off!) -> hold all three buttons, let it power on, let go. DONE.

just follow this video it helped me a lot to unlock my boot loader
