Nexus bootloader not recognized

Hey guys , I have a big problem right now.
About a week ago I unrooted my phone to get to stock ics to be able to receive the jb OTA and eventually I did. However, I'm unable to re root mg device :/ whenever I go into fastboot mode my phone doesn't get recognized by my pc ... I've also tried almost every single driver there is( pdanet, Google drivers, Samsung drivers) and still it won't get recognized :/ any help?
Also, my power button is broken so I get into fast boot through adb

All it says in command prompt is "waiting for device".. I googled how to fix it and the only answer is to install the drivers but I've already installed them and still no luck :/

try to type "adb devices". does any numbers appear?
if yes, your pc is recognizing your nexus.
if not try to unplug all usb from your pc, restart ur pc and try again with only ur phone plugged in

adb does recognize my nexus the problem is that fastboot does not. fastboot devices does not show anything.

ok so the problem really is your fastboot mode wich is broken in some way...
i think u should talk with a dev.
if anything that i said helped or learned you something please hit that thanks button

Where did you get fastboot? The SDK Or from one of those things people to toss together for people to root/unlock?
After reading the thread its tough to know for sure if there is anything you can do or we can do to help. So I suggest downloading the latest Android SDK if you have not done so already. If that still don't work or you already have it what does device manager ( on windows) show when your phone is connected to the PC while in the bootloader/fastboot?

I download fastboot and adb from the SDK and I have the most up to date one. Also when in boot loader mode the PC does not show my phone connected.
Btw, my power is broken and I don't know if that might be the problem :/

try connecting ur phone with pc and check if its being detected by ur pc or not.
if not seems like u have bricked ur device. (dont worry, this happened many times with me and our device is very easy to unbrick).

Do you have an usb jig? If yes, connect it and see if it turns on. As for connecting to pc, see if phone is detected by odin.
If possible, Try another battery.

it doesnt even show samsung logo that appears before bootanmanion

Try connecting phone with PC in APX mode and if its being connected then you can perform unbricking process. (For how to do it? and more info. Refer tut in my sig).

its great, now u can do unbricking process or can give to SSC, they will fix it for free

Don't worry buddy.. Ssc will change motherboard for you.. I had this issue too.. Phone unexpectedly turned off and just refused to turn on.. Since its in warranty you'll not have to pay anything..

Are you able to mount to windows when connected to usb in recovery?
Also what happens when you power it on holding both power + volume (bootloader mode)?

reinstall drivers and check that when u plug it in, the pc is seeing the nexus go to device manager and see if its recognized mand doesnt have an exclamation sign, if there is one, while plugged in, reinstall the drivers
to learn how to install drivers and getting the correct files: http://nexusshacks.com/nexus-s-root/how-to-root-nexus-s-or-nexus-s-4g-on-ics-or-gingerbread/
or try to flash stock via fastboot (maybe u will need to reinstall the drives, just check if its recognized under device manager):
little tutorial i made for another guy once (sorry my english and accent): http://www.youtube.com/watch?v=10_N_vV-7NQ&list=UUTsL8yOHOK7IUQl2tsKId5A&index=1

eventhough in the thread they say u need java sdk and all that u only need fastboot file and the rom image donwloaded the google dev website

Well I hope when u say "it doesn't do anything" that u weren't expecting something to pop up on the screen. If it mounts u can only tell by clicking.... My computer then drive "___" its probably drive f or g.
If it pops up then ur good. Add the ROM & gapps.
But worse case do what the previous post suggests.
Good luck

Uninstall all N5 drivers and uninstall the device from device manager. Dis- and reconnect the phone to the pc and manualy choose to install the drivers from android-sdk/extra/google/usb_driver. That should do it, works fine for me.

Alright let me try that real quick
