weird problem trying to unlock nexus s

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.

Anybody have same problem? or can be solve this problem??
thanks.

Do you get to the bootloader screen on your phone? Are you drivers recognized? Check the Windows device manager. Reinstall the drivers and make sure they are correct and recognized. What guide are you following and what version of the phone (see Hardware variants) are you using?

my phone doesn't woking..T.T
when i turn on the phone only shows google logo, so i going to recovery mode then connect computer then type fastboot oem unlock then phone screen shows up bootloader screen.
BUT, when i choose bootloader screen to "YES" then phone never change..T.T

recovery mode and bootloader are 2 different things ...
push volumen+ and power button about 5 seconds , you should go into bootloader
if you were able to get in recovery , you should have been through bootloader
connect to your PC when you are in bootloader , install driver and then type that command

yes, i installed sdk my computer. but still not working.
even i download PDA program for android driver. BUT STILL NO LUCK,.

Weird u should have an Unlocked icon underneath the Google Logo when it reboots but I think it automatically sends you to fastboot mode and at the center in red should say unlocked... u should then opened command prompt and flash recovery. I use the thread I posted. This is what I did from the very beginning.
Cd c:\nexussrootnew (enter)
>fastboot devices (enter)
"Device serial number"
>fastboot OEM unlock
----yes----
"Reboots back into fastboot mode"
Command prompt again:
Cd c:\nexussrootnew (enter)
>fastboot devices
"Device serial number"
>fastboot flash recovery (space)
recovery3101.img
(Flashing device)
"Ok"
"Back to phone"
Enter into recovery and go into mount SD card ... once u mount u will then drag the superuser.zip "provided within the file it asks u to download in link provided in my thread" into root of SDcard ... unmount and go back until u see flash zip from SD ... enter and find the superuser.zip ... that's it your rooted =]

I have the same problem
I have the same problem...
- Phone is stuck on google screen
- Installed all drivers and fastboot recognizes the phone and shows its serial number
- Typing "fastboot oem unlock" in the command promt
- Reach the bootloader unlock screen, select YES
---> The phone is left stuck on the bootloader unlock screen...
Have tried this over and over again, always ends up getting stuck on the bootloader unlock screen...
I have rooted many phones and am knowledgeable on the rest of the process (root/recovery, rom etc...), but I just can't pass this one step which is suppose to be ridiculesly easy.
Any advice?

unlock bootloader doesnot work
We all know the standard commands to unlock the bootloader but for some reason on my Nexus S device, the bootloader unlock is not working. Here is what I did,
1. Connect the device and type 'fastboot oem unlock'
2. It brings up a menu to select "No" or "YES" to unlock options...I navigated through volume up key to select "YES" to unlock boot loader.
3. Now I have to restart the device by pressing power button, the POWER BUTTON doesn't respond there by bootloader unlock doesn't complete.
4. It just hangs in bootloader unlock screen forever.
Does anyone faced this issue? why this happens??
please help me out.
Thanks and regards,

You need to be in the boot loader for that to work.

I've the same Problem. I'm in the bootloader and it says Fastboot Mode but the device is not recognized via USB.
Therefore fastboot is just waiting for devices.
Any suggestions? When my nexus is booted i can connect it als USB-Storage and so on.

I fixed it using the sdk drivers and the fastboot and adb files from the sdk (path/android/platform-tools).

Didn't work for me. I'm always using SDK.
My Bootloader is unlocked. (the little lock ist opened )
I just tried it on a completly different computer. just setted up a new SDK on my laptop.
Am I doing something wrong?
I've USB-Debug Mode enabled.
I boot holding VOL up + Power Button to enter the bootloader
Plug in the USB cable
and then i try ~android-sdk/platform-tools/fastboot flash recovery myrecovery.img
Here my Fastboot says wating for device.
If i'm booted up on my rom i can connect via adb and get a my device via adb devices.
Probably something wrong with my fastboot.exe?

[Guide] Returning to Stock and/or Unbricking your device Updated for Android 4.3!!!

First of all, I am in no way responsible for anything you do to your tablet period.
I have seen a couple of people asking how to return the Nexus 7 to stock after it has been unlocked, rooted and so on, so I figured I would write a quick guide as its super easy to do. Also, please make sure you make a backup of anything you don't want to lose. This is important.
Before you begin, please make sure you have ADB and Fastboot drivers installed and working.
1) Download the factory image for the Nexus 7 at https://dl.google.com/dl/android/aosp/nakasi-jwr66v-factory-d341d356.tgz
2) Extract the factory image into the same directory as your ADB and Fastboot executibles (e.g. "\android-sdk\platform-tools")
3) Plug in your device. If you are booted into Android, open a command prompt to your ADB and Fastboot directory, then type
Code:
adb reboot bootloader
If your device is powered off, press and hold both volume keys and the power button simultaneously. After holding all three buttons for a couple of seconds, your bootloader should launch. This should reboot you into the bootloader.
4) Type
Code:
fastboot flash bootloader bootloader-grouper-4.23.img
5) Next type
Code:
fastboot reboot-bootloader
6) Now type
Code:
fastboot -w update image-nakasi-jwr66v.zip
7) Optional: If you would like to relock your bootloader for warranty or security purpouses, make sure you are in your bootloader screen again and type
Code:
fastboot oem lock
8) If your tablet hasn't already rebooted automatically, type
Code:
fastboot reboot
That should do it. You should now be on stock Android 4.3 and ready to send in your tablet for warranty purposes if you so desire.

Also, thank you to XDA user Shano56 for the formatting help on this post.

2) Download the factory image for the Nexus 7 here
3) Unzip the factory image into the same directory as your Adb and Fastboot drivers.
4) Plug in your device. With the device on the home screen, type "ADB reboot bootloader" or if your device is off, press and hold both volume keys and press the power button. After holding all three buttons for a couple of seconds, your bootloader should launch.
5) This should reboot you into the bootloader. Now type "fastboot flash bootloader bootloader-grouper-3.34.img"
6) Next type "fastboot reboot-bootloader"
7) Now type "fastboot -w update image-nakasi-jrn84d.zip"
8) Optional: If you would like to relock your bootloader for warranty purposes, make sure you are in your bootloader screen again and type "fastboot oem lock"
9) I don't remember if the tablet automatically reboots at this point but if it doesn't just type "fastboot reboot"
That should do it. You should now be on stock Android 4.1 and ready to send in your tablet for warranty purposes.

Not a bad idea. Done and done. Also, I have proofread it several times over to ensure it is correct but would you mind making sure that all of the commands were typed correctly. My eyes are going crosseyed over here.

Assuming you have a nandroid, can you boot into the bootloader, and simply ADB reboot recovery? Or does that bug prevent you from even doing that?

In some cases due to the CWM not being official it cause bootloops by going to recovery in the bootloader.

Assuming you have already flashed CWM, then the command would actually be fastboot reboot recovery. Not sure what but you speak of.

Yes. There sure is. If you have Rom Manager installed it can be flashed directly from there.

I dont think you can really hard brick this device anyways

I'm sitting here at the command prompt with it on "erasing userdata"
It's been a couple minutes and I'm freakin' out! How long is it supposed to take? Everything flashed correctly, if I start the device now will there be an issue?
EDIT: Nevermind, just rebooted from the bootloader in the tablet and it booted fine. I'll get the OTA to 4.1.1 and that should probably fix any outstanding little issues.

hard brick?
I am stuck at the Google logo with a padlock and I'm pretty sure I have a hard bricked tablet. fastboot doesn't see the tablet or my computer for that mater through dmesg.
I've rebooted it countless times with vol + and vol - pushed and any combo thereof. It will only turn off completely when the battery dies because holding down the power key for 10 secs just reboots it back to the Google logo in about 5 seconds. I guess at this point I'm just waiting for Google to give me a RMA for a refund and I'll move on unless someone has any other ideas?

Pressing and holding the Volume down + Power buttons works just fine to launch the bootloader (at least for me).
No need to press (and force) the entire volume rocker button at all.

Try and press and hold just the power button for 30 seconds or so to re-boot the tablet and you should be fine and it should boot up just fine. From fastboot you cannot go into cwm recovery because of a bug.

I'm trying to return to stock but get this message in the window from the ADB command after flashing the stock ROM:
​FAILED (remote: (FileWriteFailed))
Anyone seen that before or have any ideas to fix?
I tried wiping cache/factory reset from CMW but no joy.

Thanks. Worked for me. I did get worried when i got (data transfer failure (too many links)) error when trying to flash the bootloader.
Turns out it was the USB port. I switched the ports and all was well.
But I followed the commands in side the flash-all.sh file
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.34.img

Nuts. I tried it on many USB ports and did your commands one by one. Ended up in the same spot. It happens when writing 'userdata'...

Locked bootloader but with TWR and rooted.

Two days ago, I unlocked my bootloader and it wiped everything. After that, I installed TWR and rooted the device with a toolkit.
Now I don’t know what went wrong, but I would like to flash CWM recovery instead of TWR, but...
it’s now showing that my bootloader is LOCKED.
And I cannot unlock after I’ve tried using adb, cmd, or the toolkit.
I will hold Vol Up+power to enter fastboot and as soon as I hit “unlock bootloader” or enter “fastboot oem unlock” in command, the phone immediately starts into TWR.
Without an unlocked bootloader, I cannot flash anything via the bootloader.
Any help would be appreciated. Thank you!

Turn the phone completely off. Hold volume up + power, plug the phone in via USB (ensure that you have the drivers installed for the phone)
fastboot oem unlock
fastboot reboot
then go back into volume up + power (fastboot mode)..... fastboot flash recovery <recovery-name>.img while the recovery file is in the fastboot.exe folder. then boot into recovery.

You see, I cannot even get to the part where I reboot the phone myself because the phone automically does it for me and jumps itself into TWR recovery and does not unlock the bootloader for me.
It takes less than a second from when i run the command "fastboot oem unlock" to when the phone reboots. Then it take about 15 seconds to get to the TWR recovery.
The only drivers I've installed on my Win8 (tried Win 7 as well) are these:

I actually had that happen to me too. When I typed fastboot oem unlock, my phone just instantly rebooted. But the bootloader was still unlocked. Use http://forum.xda-developers.com/showthread.php?t=2788632 and start from scratch. Use Universal Naked Drivers 0.73, they work amazing. I had these drivers installed before so I didn't even need to install drivers.

I actually had that happen to me too. When I typed fastboot oem unlock, my phone just instantly rebooted. But the bootloader was still unlocked. Use http://forum.xda-developers.com/showthread.php?t=2788632 and start from scratch. Use Universal Naked Drivers 0.73, they work amazing.

I tried your method but I keep restarting to the twrp recovery.
and specific thing that made the device unlock the bootloader. Fastboot OEM unlock just restarts my device
I have the correct drivers the win 7 pc does recognize the device in fastboot mode.
thank you

Silly to ask, but you unchecked the cm update in dev settings and enabled debugging?
Personally, my second lappy didn't even list the device in fastboot, but the commands still worked.
I would just boot into fastboot and run the all the commands in series.

I've already tried this on 3 different computers.
I don't see how having dev mode would affect bootloader if I never boot into the OS.
Someone had the same issue and had found a fix. I will give this tampering fix a try:

Two days ago, I unlocked my bootloader and it wiped everything. After that, I installed TWR and rooted the device with a toolkit.
Now I don’t know what went wrong, but I would like to flash CWM recovery instead of TWR, but...
it’s now showing that my bootloader is LOCKED.
And I cannot unlock after I’ve tried using adb, cmd, or the toolkit.
I will hold Vol Up+power to enter fastboot and as soon as I hit “unlock bootloader” or enter “fastboot oem unlock” in command, the phone immediately starts into TWR.
Without an unlocked bootloader, I cannot flash anything via the bootloader.
Any help would be appreciated. Thank you!

Hi lemonspeakers,
sadly I don't have a solution, but the same problem.
Current state:
Bootloader locked
TWRP installed
no root
Sending "fastboot oem unlock" causes reboot to recovery.
Besides that the phone is fully working. (My friends thing I'm crazy because I'm sad about a fully working, "normal" phone
I hope somebody have suggestions to fix the issue.
Update:
I've just seen the tamering fix thread and I'm going to try that, too,
Did it work for you?

I haven't tried it because i'm out on vacation for a few days. I didn't want to bring my new oneplus with me.
If you tried that fix, let me know how it went. thanks!

Actually, I tried it and... It works!
I flashed the script, than used this guide (again):
http://forum.xda-developers.com/showthread.php?t=2788632
Than it looked like the only improvement is, that the bootloader is now unlocked. Root didn't work.
I could fix that by going to Recovery, factory reset, reinstall SuperSU an reboot. My phone now is finally rooted.
I think the factory reset part is strange, but I'm so glad I now have a rooted OPO.
When you try it, please let me know if you also have to do a factory reset.
