Fastboot mode - Nexus S Q&A, Help & Troubleshooting

I have a sprint nexus s 4g on ICS 4.0.4 still on stock never rooted or unlocked, and I can't put it into fastboot mode when I press the power and volume up button I get a menu with four options reboot bootloader, reboot, recovery, and power off. Am I missing something ? I tried to search and didn't find anything.

That's exactly what fastboot mode is. You did it!

So why when I type in cmd fastboot OEM unlock it says waiting for device?

Because your device isn't recognized by your computer. Or in other words, you didn't install the drivers/install them properly.

Turn it off first. Then hold power & volume up.

adb drivers are not the same as fastboot drivers sadly. Once you're in fastboot mode, check your devices in Device Manager and see if there are any unrecognized or anything like "Android Device" or something. One tip is install PDAnet on your PC, it will do fastboot drivers for you (it works for me but others have varying success)

After reading your post again, I see that you were looking at the bootloader screen... I initially thought you were looking at an extended power menu.

Yes.
As a previous poster stated you don't got fastboot drivers installed.
Adb and fastboot are not the same

Looks like a problem solved just search the forum for fastboot drivers and you'll be good to go

Power button help

My power button is kinda dead I can shut off the phone and turn it on but going through recovery is impossible. How can I still flash roms
Sent from my Nexus S using XDA App
Do you mean that in recovery it will not select items?
Sent from my Nexus S 4G running CM7/franco.Kernel
I use Fix Broken Pro widget to lock the screen and No Lock app to unlock using volume down button.
I go to recovery using adb or Rom Manager. Then use back, menu, search, home buttons to go back, Scroll Down, Select and Scroll Up respectively.
Yea I can't select options in recovery or it'll continuously select reboot bootloader and I can never get into recovery mode

I guess I need to learn to flash through adb

If you are using cwm recovery, you don't need power button. Touch buttons are enough.
In CWM, do you see a message that says back button has been disabled? Somehow last night this was happening to me but in my case I simply pulled the battery and rebooted and all was fine. If it's acting up in the bootloader though I would suspect you have a hardware issue.

When I hold volume up and the power button to boot into the bootloader I can't select reboot recovery it just keeps selecting reboot bootloader since my power button is messed up

Actually issue resolved thanks to rom manager

power + volume up, then use 'fastboot devices' in adb see if it comes up.

Power+up is good for boot loops but if you have a recovery installed you can access it through the boot loader menu

No, stay on the bootloader interface, don't press anything, connect it to ur PC and type this in adb: fastboot devices see if you can see your phone's serial number.

That's bad, I recommend to hand it in for repairs, since you can't even connect it to a PC nor boot into recovery.

hi.... i need help!!!!
i have the same problem stated above . my phone automatically switches on if the battery is inserted. i cant use the volume keys when in fastboot mode(even the power key doesnt work). any advice ??? i have done remedies to the best of my knowledge though...should this phone be brought to service (center)??? im running on stock ics 404

[Q] Phone wont boot or enter download/recovery

i'm not sure what happened, but today my phone just turned off and now wont boot. everything on the phone is stock (ICS update) and i have no never messed with flashing any roms. what happens is the phone turns on, gets to the start screen, then crashes. after crashing it will vibrate continuously until i remove the battery. i have tried to enter recovery and download mode but the phone just crashes and i never see the screens..what can i do?
Buy a USB jig. Might work, its a pain to enter recovery/download .
its your data that needs clearing

thanks, i wasn't sure what this was, but after a bit of Google searching it seems something ill definitely try. everything seems to say that the phone should be completely powered down to use the jig though. will it be a problem that i dont seem to be able to get my phone to that point? the second i put my battery in the phone attempts to turn on, and after it crashes it will just vibrate non stop.

yes, the Samsung logo will come up, and then it will go to the normal boot screen where it says "Samsung galaxy s blaze" with the blue loading bar under it. the bar will stop loading at some point and then it will crash

You can boot into recovery but it is annoying. If you have adb installed you can write:
Adb reboot download or adb reboot recovery really fast.
If not a jig may be the only option.

no, but i have successfully factory reset once before.
Okay that's nice to know... To enter download mode your phone has to be connected to your pc via usb cable, to enter download mode what you do Is hold the power button, volume up, and volume down button while the phone is off, once it powers on and you see the Samsung logo release the power button but continue holding the volume up, and volume down buttons this will put the device in download mode, have you ever used Odin before?

[Q] I accidentally used a fastboot "boot" command to flash a recovery img

I'm pretty sure I'm bricked now. Black ATT One X. Flashing updated twrp so I can flash 4.4 roms, but wasn't paying attention and typed boot instead of recovery out of habit. Now my phone only goes to htc splash screen and turns off again. I can't get into recovery or fast boot. I'm bricked aren't I?

I'm assuming you are holding down the power and volume down keys at the same time to get into the bootloader?
Sometimes you have to hold both buttons (power button and volume down button) for 10 to 15 seconds. I've had to do this multiple times in a row to get out of a bootloop in the past.
If the phone attempts to boot and you can see the splash screen then you are not bricked yet. Bricked means nothing happens when you push the power button.

Yes. Doing that doesn't do anything until I take my fingers off, then it tries to do a normal boot and powers off again.
What command did you type exactly?
There is a fastboot command for just booting a recovery.IMG (fastboot boot recovery.img), but it wouldn't cause the problem you are having. It would just boot you into that recovery without actually flashing it.
Edit: what are your phone specs?... i.e. carrier, hboot version, etc...

Try holding the volume down button while the phone is booting, keep holding it and when it begins the loop again hopefully it'll get you to bootloader.

If what I suggested doesn't work and there's absolutely no way to get to the bootloader or get fastboot to work, you're kinda screwed. You'll probably have to try getting a jtag repair done, I think that'll be your only option.
I doubt a moderator is going to bump up a new user's status just because you need to reply more often, it doesn't really work like that.

Agreed. Unless you can get fastboot access back to overwrite your boot partition, your in a pickle. In any event, hopefully this will serve as a lesson to you concerning the detail and care you need to show when it comes to altering your phones.

Can't boot phone

Hey guys, I can't get my phone to boot up after flashing something that it didn't like and I can't get back into recovery because my volume buttons don't work. Anyone know of a way I could get it into recovery another way. When I turn the phone on it only boots to the warning about my bootloader being unlocked and that's it! Help, please!!

I don't think that's gonna work. I've already taken the whole phone apart and I got to where the buttons push and there were like no buttons there. I figured the little buttons should look like the power button, but they didn't.
