You're getting Signature verification failed using fastboot flash recovery filename.img?
If so ensure a few things - 1.) you've got the correct file name and 2.) you have a good download of the img.

Filename is correct and img seems OK.
Boot Nexus S into Recovery Mode with USB debugging on

fastboot flash recovery recovery-clockwork-3.0.2.4-crespo.img

The error message did not say anything about signature verification failed. The problem is fastboot cannot find the file you specify in the command line.
SOLUTION: you have to go into the folder that you saved the "recovery-clockwork-3.0.2.4-crespo.img" (for example, if you saved the file in C:\android\) using the following commands:
Code:
c:
cd android
fastboot flash recovery recovery-clockwork-3.0.2.4-crespo.img

I have already set Path variables in Windows for the Andriod tools folder which contains Fastboot and the Recovery image file.
Could the problem be with the Android driver or Android 2.3.4 GRJ22?

No - Fastboot can't find the file.
c:\Downloads>fastboot flash recovery fakefile.img
error: cannot load 'fakefile.img'
This takes place before checking if your device is connected, if you are unlocked to write the recovery, etc.
You're sure the cwd of the cmd prompt is the directory you downloaded the file to? Alternatively provide the full path to the recovery image.
Edit: Rereading your post above you have the recovery file in the directory as the tools. This won't resolve via the path. You either need to cd into that dir or provide the full path. Fastboot takes a local img file as the argument (local to your cwd unless you specify the full path).

Got it!!

You were absolutely correct with the cd\ command.

You can either try reflashing or hook it up via adb and run a logcat - it will show you what it's hanging on or waiting on. Unless it's stuck *very* early on you should be able to adb shell and then run logcat.

Same problem here - Fastboot repeatedly returns "error: cannot load recovery.img" when trying to load CWM
Tried this solution:

but I get "The system cannot find the path specificed." when "cd android" is entered.
- ";C:\Program Files (x86)\Android\android-sdk\platform-tools;C:\Program Files (x86)\Android\android-sdk\tools" is the path
EDIT: Fixed.
1) Moved .img file to root in C:
2) c:
3) cd\
4) fastboot flash recovery recovery.img
Got it finally.

Trouble installing new recovery

Im trying to get my new XOOM from unlock to root and having a nightmare!
I have read and followed guides from the forum but still can't get the new recovery on?
I have done fastboot oem unlock and followed the instructions on the tab and at the end it says complete. Next once it reboots enabled usb debugging and rebooted into bootloader, all ok so far but when I try to run the command "fastboot flash recovery recovery-tiamat-r4c-100611-1150-cwm.img" it comes up with "cannot load"? I have tried with and without the. img at the end and also renamed the file "recovery" and "recovery.img" and still the same thing.
Has anyone had this same problem and can get me back on track please.

if you have adb installed.
copy files from platform tools folder to "tools" folder.
put tiamat recovery image in tools folder.
rename recovery..tiamat as recovery(not recovery.img)
commands:
adb reboot bootloader
fastboot flash recovery recovery.img

Ok, will give it a try when I get to my computer and will report back.
Thank you

First of all, it really doesn't matter if all your files that you need are in Tools or Platform tools, as long as they are all in there and your command window is operating out of that folder.
Second, you are making a good point re: the img file extension...in Windows, it sometimes is set to hide file extensions, so it is possible that someone could already have the img file extension there and not see it and add it again, making recovery.img.img which of course wouldn't work.
I don't think this is the OP's problem, but you never know.

I'm lost installing CMW

OMG yes i know im a newb but there is a first time for everybody for anything.
So i'm trying to unlock, root, install cwm and install custom roms but ive looked at all the instruction from many thread and a lot of them had missing steps
Anyways, i've downgraded from JB to 4.0.3, rooted, unlocked and now i'm trying to install CWM. So i installed android SDK and all tools, i've put recovery image in same folder as fastboot.exe, i've booted the tablet and selectied USB icon but wtf do i do now??
I'm basically here:
** FastBoot Method **
1) Install Android SDK
2) Download CWM Recovery image from the original thread and check the MD5 sum (don't skip MD5 check,is there to make sure the file is not corrupted)
3) Copy the downloaded file in the same directory as your fastboot.exe (unless you have /platform-tools in PATH then you can flash from anywhere)
4) Turn off your device and boot into fastboot mode (power on while holding volume down, then select the usb icon and hit volume up to confirm)
5) Plug the device into your computer
6) Run the following command via the command line:
fastboot -i 0x0B05 flash recovery recovery.img
fastboot reboot
Where do i get this command line?? is it command line from windows such as CMD?? cause if it is, i've tried it and nothing. Do i have to point to where is the recovery image?? Its in C:\Users\Patrick\AppData\Local\Android\android-sdk\platform-tools but i'm lost from that point, i'm not sure what command line i have to use, and how to set it up so i can tell it where to look.
Can anybody help me please?

change directory to the folder the recover/fastboot is in, using the CMD on windows. So:
"cd C:\Users\Patrick\AppData\Local\Android\android-sdk\platform-tools"
make sure the recovery is called "recovery.img" and that its in the "platform-tools" folder alongside the fastboot.exe, then run the commands:
"fastboot -i 0x0B05 flash recovery recovery.img"
and
"fastboot reboot"

Yes, command line is in your PC. The location of the fastboot.exe located in c:\android-sdk\platformtools (if you install from sdk).
On your PC, open CMD and navigate to the above directory where fastboot.exe is. Make sure your recovery.img in also copied to this same folder. Now you can execute the fastboot comand:
fastboot -i 0x0B05 flash recovery recovery.img
fastboot reboot

I think it's easier for you to download Voodoo OTA root keeper to preserve root, then upgrade to JB, then use OTA root keeper to restore root. After this you can install TWRP recover by download goomanager from the play store and install it, once you have twrp, you're home free.
Currently you are on ICS, becareful if you use a wrong version of cwm you could brick your device. Many ppl installed ICS cwm version then upgrade to JB without the right version and they bricked.

Pat,
If it makes you feel any better I had a heck of a time with this myself.
Once I realized I had platform tools in a folder on my PC desktop with the command prompt
in it I was able to flash.
Gotta say it wasn't easy to figure out in bits and pieces.

Thanks guys, you've been REALLY helpful! I completely forgot about the shortcut to open cmd in a folder, and i'm not sure if you were wrong or its because im on windows 8 but its ctrl + shift + right click
EDIT: now i get a problem, it do all this and i get "waiting for device"
i tried different USB ports, same deal...any ideas?
EDIT: EDIT: tried all USB port but one, the last one i used did the trick, thanks for all!

I'm having this exact same problem but changing USB ports is not working for me and I tried everything else. Would it help if I tried a different computer?

I don't mean to threadjack, but this portion of your post caught my attention.
I just swapped a prime for an infinity. I rooted, installed rootkeeper, preserved root, upgraded to JB and restored root.
Are you saying I can install goomanager and update recovery without unlocking via the Asus tool?
If so, sweet!

No. You will still have to unlock the bootloader to install a custom recovery, unfortunately.

What stage are you in? Have you got clockworkmod-recovery installed?
I assume you are referring to superuser zip file. DO NOT unzip it, copy the zip file into your Nexus S sdcard, any folder.
Copy clockworkmod-recovery image file to C:\Program Files\Android\android-sdk\platform-tools\
1. Reboot into recovery: Power off, hold Vol-Up and long-press Power button. This should get you in FASTBOOT MODE
2. Flash clockworkmod recovery via fastboot: Go into Windows command prompt
Code:
cd C:\Program Files\Android\android-sdk\platform-tools\
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
3. Once fastboot is finished, choose "RECOVERY" option on FASTBOOT menu. That should put you in Clockworkmod Recovery menu.
4. Select "install zip from sdcard"->"choose zip from sdcard" and select the superuser zip file that you copied earlier.
5. Reboot and you should be rooted.
Hope this helps.

OK
So it says sending recovery. But its just stuck on saying that and is it supposed to take long?

If you are on stock rom, clockworkmod recovery may be replaced by stock recovery upon each boot.
You can re-flash clockworkmod recovery each time you need it, or disable the recovery restoration. Search this forum for instruction on how to make recovery stick.

Have you got Android SDK-tools installed? Did you install the "Platform Tools" package via SDK manager? fastboot.exe is not installed by default. You may want to install USB driver too. See attached picture.
Test if fastboot is available and working: plug nexus s to pc:
Code:
cd C:\Program Files\Android\android-sdk\platform-tools\
fastboot devices
If usb driver is working, you should see some device id being displayed.

[Q] [Problem] Cannot flash recovery

Hi All.
Hopefully someone is able to help me. I'll try to give as much information as I can.
I have followed the following guide to root my nexus 5.
I have rooted it successfully last month.
However, I have accidentally installed a OTA update from google this week (Android 4.4.3).
Just a while earlier, I have decided to flash a custom rom.
So, as usual, I reboot my phone into recovery.
However, the recovery shows the android with a red triangle, stating "no command".
I have read the forums and read that this is actually not an error but it is the default recovery for android. (Edit: Ok. Maybe its not the default recovery. Anyone able to give me advice on this?)
I guess that my recovery was returned to the stock recovery after the OTA update.
So I tried to flash CWM recovery using ROM manager, but it states "An error occured while flashing your recovery".
I decided to restart my phone and to try it again, now it stucks at 100% on ROM Manager.
I have also tried to flash recovery.img using fastboot. However, it didn't work too.
It returns with an error: "cannot open recovery.img"
May I know if anyone can help me with this problem?
More info on the current status of my phone:
Bootloader unlocked. (Checked by trying to unlock it again. System states that process has failed as it is already unlocked)
ADB Device: Detect-able.
Fastboot Device: Detect-able.

It is indeed the stock recovery. OTA returned it. It also removed root so rom manager won't work, but you shouldn't use rom manager anyway.
You'll need to download a recovery and flash it using fastboot .
Please describe the exact steps you took to get the fastboot error. Screenshot of cmd would be very helpful too please

What I did is to check if the boot loader is unlocked.
And yes. It is unlocked.
So I carried onto checking if fastboot detects my devices by doing "fastboot devices". And my nexus5 gets detected.
Then I moved on to trying to flash recovery using " fastboot flash recovery recovery.img ".
But the error appears at this point. And I'm stuck.
Is this sufficient?
Do note that I did change the file name to recovery and not recovery.img as most files do not include the file type in the file name.

Try flashing the recovery using dd (You need root)
Boot the phone normally and push the recovery.img using adb and flash it:
Code:
adb push *Path to recovery.img* /data/media/0/
adb shell
# dd if=/data/media/0/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
I hope this helps.

You would be better served setting windows not to hide known file types to be honest.
A screenshot of your fastboot flash attempt and error would be most useful please

He hasn't got root. Fastboot is his only option

Well FWIW for anyone else reading, my assumption was going to be that the OP didn't put the full path to the recovery OR didn't put the recovery in the location the cmd prompt was running from.
Would have been nice to have seen this through to conclusion, but I cannot monitor forever so I'm unsubscribing due to lack of replies.
eg:
Code:
c:\Users\Administrator>fastboot flash recovery recovery.img
If there is no path to recovery image as above, then the asumption to cmd is that the recover image is in c:\users\administrator (Which it probably isnt)
If it is on the administrators desktop you would:
Code:
c:\Users\Administrator>fastboot flash recovery c:\users\Administrator\Desktop\recovery.img

Hi All.
Hopefully someone is able to help me. I'll try to give as much information as I can.
I have followed the following guide to root my nexus 5.
I have rooted it successfully last month.
However, I have accidentally installed a OTA update from google this week (Android 4.4.3).
Just a while earlier, I have decided to flash a custom rom.
So, as usual, I reboot my phone into recovery.
However, the recovery shows the android with a red triangle, stating "no command".
I have read the forums and read that this is actually not an error but it is the default recovery for android. (Edit: Ok. Maybe its not the default recovery. Anyone able to give me advice on this?)
I guess that my recovery was returned to the stock recovery after the OTA update.
So I tried to flash CWM recovery using ROM manager, but it states "An error occured while flashing your recovery".
I decided to restart my phone and to try it again, now it stucks at 100% on ROM Manager.
I have also tried to flash recovery.img using fastboot. However, it didn't work too.
It returns with an error: "cannot open recovery.img"
May I know if anyone can help me with this problem?
More info on the current status of my phone:
Bootloader unlocked. (Checked by trying to unlock it again. System states that process has failed as it is already unlocked)
ADB Device: Detect-able.
Fastboot Device: Detect-able.

Hi. Sorry for late reply. Was at work. I'll try out the full path. What I was told is to just put the recovery IMG into the same folder as fastboot and it should do the trick. Will post screenshots after trying out.

Ok thanks.
Did you turn off "Hide known file types"? can you screenshot in Windows explorer, the location of the recovery image with hide turned off and in "details" view please?

Yes. I did. Here are the images.
I'm using windows8. So it may look a little different.

If I gave you a few steps to try and rule out some variables to narrow down the fault are you happy to do them?
My first thing to suggest would be to take a copy of the "platform-tools" folder and drop it on the root of c: (meaning ensure c:\platform-tools exists)
Then right click Computer > Properties > Advanced System Settings (A System Properties pop up will be shown, in the advanced tab)
In the pop-up, press "Environment Variables" and in the bottom window, called "System variables" scroll down to the entry called "Path" and press edit.
Scroll to the very end of the line of text. Add the following to the end of the line with no spaces (and no quotes obviously)
";c:\platform-tools" and click OK to all windows and pop-ups. Just to break that down, it is a semi colon ; followed by the path to the platform-tools folder.
Give yourself a restart.
What this does, is gives you the ability to call the fastboot command from anywhere. So instead of typing Desktop\adt-bundle......\platform-tools\fastboot flash blah blah, you can literally just type "fastboot flash" because like other commands, it is now a system variable.
Then put the recovery.img in the directory that cmd opens up to which appears to be be "c:\users\blah"
Then open cmd and do the basic command with no paths.... fastboot flash recovery recovery.img
Let me know,
Thanks

I have tried it. Still doesn't work. (Screenshot as attachment)
Could there be a problem with the phone instead of with the path/common errors?

Did you check if the MD5 of the recovery file is correct? (to rule out a bad download)

Re-downloaded it many times. Checked all of the md5.
Downloaded not only CWM recovery. But also other custom recovery.

no. the recovery.img is not in c:\users\username\
put that file there, then retry your command
OR
fastboot flash recovery c:\entire\path\to\recovery.img

Pretty sure it is the image. Downloaded from the website itself. They only comes in .img and not in zip.

Ah. It just worked suddenly. No idea why. But I guess @rootSU 's suggestion works well.
And maybe also @Zepius 's suggestion.
Here's what I did to help others who have the same problem.
I did what rootSU asked me to do (changing the "path" part).
Then took Zepius suggestion and duplicated the recovery img in a few folders (the original folder i'm using, on desktop, on C drive root folder)
