Firstly, the power button has gone faulty on my Nexus S and I am due to send it back to Samsung for repairs, so I want to get it back to factory image 4.0.4 IMM76D using the Google image and to relock the bootloader. However, when I reboot into fastboot all the keys stop working and I presume it has stopped responding and the only way to reboot is to do a battery pull. Just wondering if anyone has had this experience before and knows a solution.
By keys you mean volume and power right?
Does a computer recognize it with fastboot. Example . Fastboot devices / fastboot reboot etc?

Volume and power keys don't work while in fastboot and it isn't recognised by that. And when it powers on regularly it say No boot or recovery img. Nope, doesn't get recognised by PC and just says No devices found...
Did it work before in the same system?
Only other thing I could think of to try is download mode/Odin
It was working fine that day. I even flashed CWM on it after trying TWRP. But then suddenly the power button broke, and when I used the key combo to get into fastboot mode using the plug in to charger method it loaded fastboot and just wouldn't respond

a buddy of mine bought a nexus s off of craigslist that is constantly force closing when you boot it. it will force close everything then reboot itself. im attempting to unlock the bootloader but adb devices doesnt show the serial number like it does for my nexus s. when i hold down volume up+down and plug in the usb it goes to the unlock bootloader screen but it doesnt give you the option of yes or no. iv posted a picture to show what it looks like. i cant get the phone into download to try to fix it with odin either. any help would be appreciated.
edit: i finally got my pc to recognize it and we now have an unlocked bootloader, but now iv encountered another problem. i downloaded a recovery image and moved it to the tools folder of sdk when i type in the fastboot flash recovery command it responds with error: cannot load recovery.img.
To unlock bootloader, you have to use fastboot, not adb. So the correct command would be fastboot devices
To boot into the bootloader, you have to press volume up + power, not volume up+down and plug in the usb -- that would bring you into the Download Mode instead

i know, i used adb devices to see if my computer would even recognize the phone. i i can get into fastboot mode by pressing volume up and power but cant send a fastboot command to the phone because it doesnt recognize the phone. when i hold down volume up and down to get into download mode it sends me to the screen i showed in the pic. its the unlock bootloader screen except there is no option to click yes to unlock the bootloader. i would love to get into download mode and use odin hence why i pressed vol up and down and plugged in usb, but like i said it sends me to the unlock bootloader screen.

Before you try to unlock the bootloader I would flash the latest stock rom and see if it boots properly.

Try one of these recovery images:
http://forum.xda-developers.com/showthread.php?t=988686
The full command is
fastboot flash recovery recovery.img
(make sure your recovery image file is actually named recovery.img)
If 'fastboot devices' returns your phone's id you can flash a custom recovery. Otherwise get a full _signed_ stock rom and flash from stock recovery.
Did you install all drivers? Deinstall existing and use either pdanet or sdk build in program to get them. You need like 3 different ones.
Try locking unlocking bootloader again.
There's always the chance you got a defective usb connector.

Hi I have the following problem: after I flash Cannibal open touch recovery I could not flash any .zip file so I decided that I go back to CWM touch so I restarted my phone. Phone booted into fastboot mode with the following message no boot or recovery IMG so I decided to flash recovery with fastboot. I opened the folder with fastboot command flash_recovery connect the phone to usb but the command line always showed waiting for device. I unplugged the phone and tried to press the volume keys but nothing happened as if it freezes. I pulled the battery and try it again but no response. I cant connect phone to odin because it has broken power button and after I insert the battery it always turn on itself. Please advise me what to do thank you.
Seems your drivers have gone corrupt. Try a different system and use Nexus Root Toolkit.
I tried this option but without success. Phone does not respond to anything. No volume up or volume down. It´s just stucked on bootloader.
This link says that if you get <waiting for device> , then fastboot is not configured properly. Check out the link over here.
You may also try this command "fastboot boot recovery-clockwork-6.0.4.3-crespo.img" to boot into recovery without installing it.
no hope
The reason you cannot navigate in fastboot/bootloader is that your powerswitch is probably stuck in the "on position"...does your device immediately power on when battery is inserted?
The way i solved this a few months ago was to completly remove my powerswitch from the board power my device on..use quickboot to enter fastboot menu and input commands...
Also completely removing your power button makes powering on your nexus alot more complicated.
what i did was go to download mode (holding vol+ and -) and pluging phone in..this takes you to download mode
then you need to get a copy of a boatloader file to flash via odin which will reset your phone and power it on...pm me if interested i can provide you with files necessary
Hello all, after some water damage to my Moto G 2014 XT1068 (Lollipop) I am having a few problems and wondered if anyone could help.....
1) Volume keys not working
2) Phone only seems to boot into safe mode.
3) Rebooting phone always goes to fastboot menu.
Debugging is enabled on phone, but it is not rooted. I have installed Android SDK on my pc and have tried using adb to reboot recovery but it always comes back to fastboot menu. I have flashed TWRP using fastboot but can't seem to access it. Since the volume buttons are not working is there any other way to enter TWRP recovery mode?
Oh yeah it always says 'Fastboot reason: Volume down key pressed' which is kind of strange since in the fastboot menu and when I do boot into Lollipop the volume keys are completely unresponsive!
Thanks in advance
Hey guys, so I have this dilemma on my hands. One of my friends has a Nexus 5 that has a power button issue. It seemed like a stuck power button, because even cleaning it did not solve the issue. So I removed the power button, and it finally turned on. However, it's now stuck in a Google logo bootloop.
The Objective:
To recover all data on the device. This is a must.
The Obstacles:
- No physical power button, but I can place a pair of tweezers on the terminals on the board to simulate a power button press.
- Bootloader is locked (I can unlock it, but that erases all data on the phone).
- Cannot enter proper stock recovery (I get a "no command" error when I do; I've tried all button combinations afterwards, including the ones from HERE, but to no avail).
- USB debugging was not enabled on the phone when booting normally, so even though the phone is recognized by my PC, I cannot do anything using ADB.
- Fastboot mode is the only successful mode I can reach on the phone.
The Final Question:
Does anyone know how I can successfully recover all the data on the phone using ADB or any other method, having the above obstacles?
Thanks in advance.
If you can reach fastboot without any problem, you can try to boot a custom recovery image using the following command : fastboot boot recovery yourcustomrecovery.img
(if you dont have a custom recovery, you need to flash one with : fastboot flash recovery yourcustomrecovery.img)
It will boot in recovery mode and, I hope, allow you to have an adb access and recover your data.
edit : since your bootloader is locked, i guess this won't work.

I bit of a trick. Try 'fastboot flash boot recovery.img' but instead of kernel flash twrp. After flash do a 'fastboot reboot'. It will boot recovery. Via twrp the pc will recognize phone as a media storage. You will not erase any data

Thanks for the response, but the bootloader has to be unlocked for that to work, and while I can do that, it will wipe the data I need.
hello i m to unlock oem from adb and reboot tablet but it won't start only restart and go to boot mode volum down not working to choose fastboot
If english isn't your main language then use google translate and I'll try my best to understand.
Anyway, does adb recognize your device? Does adb devices returns devices attached and a serial number?
If so then try adb reboot bootloader
Or try manually booting with volume buttons, usually it's (Volume Up + Power) combination, on some devices it's (Volume Up + Volume Down + Power) combination.
You have to enable USB debugging and oem unlock in settings for any of this to work.
After successful booting to fastboot. Use fastboot oem unlock for older devices or fastboot flashing unlock for newer devices.
Then use fastboot reboot after successful unlocking. Note: Most devices use prompt to confirm bootloader unlocking which in turn requires the user to select "yes" with volume buttons.
If your device doesn't boot to bootloader and you have oem unlock and usb debugging on and tried all of the above. Then most likely your device bootloader cannot be unlocked, which explains why you can't find your device in XDA forums.
I did all of the above, but after unlocking oem, this is what the picture became
volumn down not working
I'm not following here, what exactly happened? Did you unlock the bootloader?
yes I unlocked the bootloader but after fastboot reboot it does not turn on it reboots only as shown in the video
Try booting into fastboot again and using flashing unlock_critical
I can not enter the fastboot mod because it does not work for me volumn down
Is your device detected on your PC? Try adb reboot bootloader
after unlocking oem, the tablet does not turn on and does not see the pc
Try connecting the device to your PC while pressing volume button to boot to bootloader. If it still doesn't boot then you can only fix the volume button.
Can you tell me what's your device model?
my model is x101 china model tablet .
boot only working volumn up
I can not choose boot mode
I never saw a bootloop after unlocking bootloader before. Maybe you modified your device in anyway before doing this? Like one click root apps or anything whatsoever?
If you can get volume down to work then you should be fine. Also try power button too pressing it should have the same effect as volume down.
I haven't modified anything. only the power button does not work only the volume up and the volume down is not pressed Please help me how to recovery system

Is your device battery removable? If so, remove it and wait 5 minuets and connect your device to your PC while pressing volume button to boot into bootloader.
If not then completely discharge your phone and wait for 24 hours. and then try connecting it to your PC while pressing volume button to boot into bootloader.

I discharged it but still nothing fixed
Hence the reason not buy cheap Chinese products. You can only take it to a service center to fix the volume down button.

If it's working then boot to the bootloader. And use fastboot flashing unlock_critical
