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.

Fastboot not responding at all.

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

Did you try Home + Vol up + power button??
EDITED:
If you are really stuck at fastboot.. You need to use ADB.
You can flash a recovery through fastboot and then a rom through recovery.
Search a little about using fastboot.

i've got the same problem .. yesterday i've done a full wipe(system , etc.) ... and i've pressed power off... my volume buttons aren't working ... how can i get in recovery?? with android flash recovery doesn't get from fastboot to recovery

If Android Flash Recovery ( AFR ) successfully flashes the recovery, you can simply pull the battery out of the device, wait a few seconds and then put the battery back in. Then manually boot to recovery. Keys -> Power + Volume Up + Home
AFR has an issue with the mode change from fastboot to ADB and from ADB to fastboot. I haven't had a chance to fix it yet.

ies but volume buttons aren't working their are broken....

Try using adb commands through your computer in fastboot mode.
If you don't know What is ADB? follow the link.
And here is the [Guide]Setting up ADB and Fastboot.

Need help! Super soft Bricked stock phone. Tried many methods!

Hi all. So my stock opo somehow got bricked overnight while charging. It's completely stock and I have no idea why.
Status of my problem:
-Stuck on Android boot screen.
-Able to access fastboot.
-Can't access recovery mode
-No TRWP
-it's still locked
-Tried unlocking with fastboot oem unlock cmd / toolbox but it just reboots back to android stuck screen after its done but its still locked after checking with fastboot oem device-info cmd.
*USB debugging not enabled (cant enable it cuz i cant go in my phone duh)
-Cm11 33r I think...
-Installed android adb on device manager
But couldn't detect it on the list ("adb devices" cmd)
-Able to detect serial using fastboot device cmd tho.
-Tried universal adp, adb bootloader driver, Samsung adb driver, composite driver and it still won't detect it on list.
-Tried using another usb port.
-computer doesn't detect phone unless I go on fastboot or hold power+up volume for 10 sec (this shows QHUSB_BULK)
-Tried using msm9874downloadtool.exe with cm 11, doesn't do anything even tho it's completed and it's green.
-Tried using msm9874downloadtool.exe with color os but it doesnt work as well, in fact, it made my screen have multiple grey lines vertically across my screen and no fastboot display or android display.
-Tried just flashing Cm11 33r images but it won't work cuz I'm locked.
-Tried unlocking but goes back to my other problem of device not being on the list and not having usb debugging enabled.
Tldr;
Phone stuck on Android boot screen
USB debugging not enabled
Phone is not unlocked so I can't flash anything
Thanks for your time and effort. I really need help.

I still need help guys plzzz. Thankss

Have you tried getting into download mode? I think you power it off. Connect to USB and hold vol down? Or vol down + power. Something like that. Once in DL mode, flash it. There's a tutorial somewhere.

download mode? you mean fast boot? power + down doesnt load anything. Power + up goes into fastboot mode.
And i cant flash anything because you have to unlock the phone first. But mine is not unlocked. And i cant unlock it with fastboot oem unlock cmd because all it does it reboots my phone. Yes i checked if im unlocked after that with fastboot oem device-info.

First try to go to recovery by pressing volume down+ power button at the same time and then clear data and factory reset. This will wipe out ur data on phone but u can revive ur device by flashing stock rom using flashing tolls available... Check youtube videos for flashing tools.
Once you clear the data and factory reset from recovery mlde then ur device will be at the state where there is no OS in it n just a stock kernel. Give it a try and let me know

I can't get into recovery. Power + down only stays at android boot screen.

Have the exact same issue. Did you find a fix???

Even if your bootloader is not unlocked you can flash stock rom. Use oneplus one flashtool and flash cm11s. There are plenty of videos available on net for these problem, just go through them or try the hard bricked video to solve your problem. I hope it helps you. I lost my one device because of a silly mistake so i know the pain.

I've tried flashing stock rom. Cm11 33r. But it keeps telling me I'm locked.

put it on fastboot mode, download the stock rom from this:
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
Choose carefully between 16gb or 64
unzip the file and click on the flashall.bat or something like that , it's a script and it will flash everything
and you should be good
you will loose all your data, i don't know if you dont flash userdata and you remove it from the file and remove it's line from the script, maybe you wont loose your data, but try it
if you want i can help you through teamviewer

recovery mode

hi, I hope I'm in the right place to get help with my issue. my Ace is in a reboot loop that i can't seem to get it out of. i have tried force rebooting and lt will not enter into recovery mode so that each time i would hit recovery mode the screen goes blank for a few seconds then the moto logo (M powered by Android) screen comes on with vibration for six seconds then again to blank repeating this loop until i again hold power and volume down buttons. I do have a lot of apps installed but this phone has a whole lot of memory that came with it. I am hoping this forum may have some ideas to help me rectify this issue. thank you.

While connected to a pc, enter the fastboot - w command. This will erase the internal memory and your phone should be able to boot.

thank you for responding. I connected my phone to my laptop but it does not detect it. my phone has, highlighted in red, AP fastboot flash mode (secure). also, tools mode: Disabled, and OEM locked

If you can reboot to recovery, try a factory reset.

thats the problem I"m having is getting into the recovery. I hold the volume down and the power buttons down till I can see the options recovery mode, but when I click on it by pushing on the power button, that's when it goes into the loop mode and never goes into recovery.

Use the Lenovo tool to download and flash the stock rom which includes a recovery.

I did what you adviced and I was instructed to enable debugging or fastboot mode in order to be able to rescue. But if I was able to do either one of those that means I wouldn't need help booting up. follow what I'm saying? because I would have to get into the settings to enable debugging or fastboot mode, somthing I can't do because my phone will not boot up.

To enable fastboot moode, hold the power button and the volume down button at the same time. This should put you in the right place. You should get red text that says you are in fastboot mode. If not, go to https://t.me/motoblankflash and ask for help.
