Its telling me that fastboot is not a internal or external command. I'm going into the cmd and typing cd filepath then the fastboot instructions. Am I missing something?
Fixed! Thanks so much!

Your welcome and so everyone else knows you have to hold ctrl and shift in the folder and then click on open command prompt.
ok i made it simpiler to follow. I decided to do this because the ota is coming and many people want stock back.
Anyone have any issues getting stock recovery back on their nexus? I have ran odin a few times with stock files and I end up with no recovery, just that triangle exclamation thing. I have tried fastboot flashing stock recovery as well as custom ones with no luck. The only thing that has saved me is shabby's one click...for some reason its fastboot flash of recovery works while doing it manually doesn't...but that doesn't put on stock recovery...
Thanks I really needed these instructions.

When I was on stock (when I first got the phone) I remember not having a recovery at all ( just the triangle) .

Petes method is better than this method guys. Use fastboot, just copy and paste the commands into the terminal. Much better than this.

OK. You obviously have fastboot drivers installed cus your rooted. Download THESE, courtesy of Pete. Extract that zip to a folder on your desktop. Open that folder, hold shift and right click in the folder and choose open command window here. Then run these commands, hitting enter at the end of each line:
adb reboot bootloader
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
fastboot reboot
That is all, takes like a minute or 2 and your back to stock. I can do it with my eyes closed
Thanks Mike

[Q] Bricked Nexus S

Hi
I have bricked my nexus s when I loaded a ROM that I downloaded.
I have used several different ROMs and had no problems.
I asume this ROM was dodgey.. Anyway I get no screen at all, the menu control at the botom of the screen lights up but that is it.
I can get to it using fastboot but it won't load any ROMS. There is no action on the Nexus screen itself.
Is there a guide using fastboot to recover this also what file/files will I need to download?
Thanks in advance any help would be much appreciated.....
If you are here looking for help you need to give us more information.
What model Nexus S do you have?
What rom did you flash?
What have you done sense flashing the rom?
My guess is you flashed a rom that isn't for your model phone. So you either have SAMOLED or SLCD. I'm guessing the rom you installed was for the screen type you don't have.
So let us have some more details so we can help.

If you can get fastboot to work, you can flash all partitions including system. Don't worry, this is an easy fix.
Hi Again guys
Firstly thanks a lot for the replys I really appreciate it.
Its a 3g the model no: is GT-19023.
Its SAMOLED that much I know.
I cannot get into recovery I can get fastboot to recognise the phone but nothing on the screen.
I have downloaded a stock rom and extracted the boot, recovery & system.img files.
I have followed the instructions below and all seems to work till I get to the system. it fails with the following message. The other steps seem to work OK.
"FAILED (remote write failed)"
I have also tried this with several other ROMs I know work on wifes Nexus s and still no luck. Some allow the system to be flashed but the phone still won't boot.
1. fastboot flash boot boot.img
2. fastboot flash recovery recovery.img
3. fastboot flash system system.img
4. fastboot erase cache
5. fastboot erase userdata
Any help would be great
I also downloaded ODIN but cant get it to work; It does not recognise that it is connected to the USB, but fastboot does!. (Is there a step by step guide to using it?)
Sorry for sounding like noob, but I have read everything and looked up these forums and tried a lot before asking for help.
GL
If your phone is a Gt-i9023 it is SLCD!!!!! Not SAMOLED.
Again what rom did you flash? Post a link to it. I still think you flashed a rom for SAMOLED when you have SLCD.

BTW, so 9020 ROMs are incompatible with 9023? I am aware of differences between those devices, but when I looked in "Development" section, there is no info, about compatibility with 9020a/t/9023
http://forum.xda-developers.com/showthread.php?t=955719
pretty sure that is the link to the ROM.
I tried to restore using another stock ROM (I backed it up from another Nexus that was only rooted and stock)... Yes it was exactly the same phone model etc.
The problem is now the error is saying ===FAILED (remote: Bootloader Locked - Use "fastboot oem unlock" to Unlock)===
I tried that (the unlock command) and the prompt just types three dots (...) and then hangs there. I have tried removing the battery etc and the same issue.
I am happy to erase the phone to nothing and load another image.
It seems that maybe this phone is cooked....
I hope not ==shattered==

ROMs are compatible between those variants! But, if you're flashing some stock ROM bundles you can flash wrong one. Because bundles contain rom, kernels and radios for specific device with specific drivers. In that case you can flash wrong driver for your display, or even something worse...
Follow what it says, unlock your bootloader first.

Your link still does not tell us which rom you flashed....
You can't flash a rooted rom through fastboot without unlocking the bootloader first. Sounds like you need to restore a factory rom with Odin.

Hi all
I got this sorted out and am really happy to have my phone going again.
For those interested or in the same predicament I was in please read on as this is how I managed to make this phone go again.
Please rmemeber this phone was really bricked no screen at all jus the menu light like in the picture in my first post.
As I stated I could get fast boot to see the phone. And also Odin. (Still no screen at all)
I had another phone the same with the original rom on board.
I rooted this phone and installed ClockworkMod recovery ad used this to backup the standard ROM.
I then rebooted this phone an copied these files from the backup into my fastboot directory (boot.img, recovery.img, system.img)
I then connected my dead phone up to my PC and ran the following commands.
1. fastboot flash boot boot.img
2. fastboot flash recovery recovery.img
3. fastboot flash system system.img
4. fastboot erase cache
5. fastboot erase userdata
I then removed the battery and to my astonisment the phone booted normally into the standard ROM.
WOW I was over the moon I have since installed my MIUI Rom and using my phone happily...
Thanks everyone for your input..

I've got a phone in the same state I am trying to revive for a guy. With the bootloader locked download mode gives you a locked bootloader screen. Odin sends the flash images to the phone, the phone verifies them but then refuses to flash them (presumably due to the bootloader being locked). The bootloader won't unlock so there is no way to flash a rom to fix the phone.

Your lucky your bootloader was already unlocked. Once a phone gets borked like that unlocking the bootloader is impossible and Odin refuses to flash.

Yes it does! Or at least on the phone I am trying to repair it has. On the phone I am trying to repair when you go into download mode you get a screen that says to unlock the bootloader. Odin connects and sends the file but then the phone refuses to flash it. If that is not the bootloader being locked affecting Odin then I don't know what is. I have flashed with Odin hundreds of times with Galaxy S phones so I know what I am doing. I have never seen Odin send a file, have the phone say it is verified and then refuse to flash it, but that is what is happening with this Nexus S with an unlockable bootloader. The files are the correct files and Odin is the correct version. If you are so smart, then you tell me what to do to get Odin to accept the flash and you will be my hero.
I have attached a shot of the phone in "download mode." Notice it is a warning about the bootloader being locked, not the normal screen with the Android bot and a shovel. Odin sees the phone (connected to computer as Samsung device) but once the phone verifies the file nothing else happens. The file is never flashed. Notice in the photo there is no YES and NO selections to unlock the bootloader like you get when you issue the "fastboot oem unlock" command. In Fastboot when that command is issued you get the normal unlock the bootloader screen but when you select YES and press Power nothing else happens. It just hangs no matter how long you leave it. A battery pull is the only thing you can do and when you turn the phone back on the bootloader is still locked.
If you are getting g stuck there you may have a hardware issue. I still think you need to try flashing through fastboot.

Cannot flash in fastboot. Sends over image then says fail due to bootloader being locked. If you have a signed update.zip with android-info and android-product files that can be flaahed in fastboot mode let me know where it can be downloaded from.

Just remember to close HTC Sync before attempting to use adb/fastboot, as HTC Sync likes to mess with the adb connection.

[Q] Softbricked Nexus 5, can't enable USB Debugging -> adb doesn't work

Hi guys
I accidently wiped my whole phone (Caches, Data, Internal Storage & System).
After reading trough the forum I found out that I need to flash the Stock image via adb/fastboot.
The problem is that adb won't recognize my phone due the lack of enabled USB Debugging (no OS installed).
I already tried it, on both, Mac and Windows.
I have no idea what I should do now. I would really appreciate it, if you could help me guys.
Thanks in advance.

1) you do not flash stock images using adb. Adb is not fastboot. They are different things
2) you can only use adb in android or recovery. USB debugging is an android only setting. It is NOT needed to use adb in recovery. Adb will not work in the bootloader
3) fastboot only works in the bootloader. It is fastboot to flash stock images.

Thank you for your fast answer.
But ./adb devices doesn't shows any devices.
And neither does ./fastboot devices.
Let's stick with Windows for now
So boot into bootloader. Adb devices won't work here as explained. Fastboot devices should. If it doesn't you need to read the adb and fastboot drivers thread

Have you tried using external micro usb flash drive with a rom + apps? I'm assuming your recovery is intact. If you're trying via win8 it's a pain #drivers.

Not everyone has a Micro USB flash drive or OTG cable.
I didn't have to try anything to get drivers working after I clean installed Windows 8.1U1, it worked as soon as I installed the Google USB driver lol. If you can't get it to work, you're doing it wrong.
