Can you erase the sdcard (external storage) using fastboot?

Does anyone know a way of erasing the sdcard (external storage) on the Nexus S using fastboot commands? i ask because i'm creating a cmd file that will return my phone back to stock using factory images and then relock the bootloader, the only problem is that the sdcard doesn't get erased when relocking the bootloader, so is there a fastboot command to erase the sdcard?

You can lock and unlock bootloader again. Then relock.
So lock->unlock->relock

Thanks for the quick reply, i had thought of that but i would prefer to just erase the sdcard (also for future reference), or, perform a relock that gives the same results as the unlock, eg: wipe sdcard, which would be better, my cmd entries are below.
fastboot flash bootloader bootloader-crespo-i9020xxkl1.img
fastboot reboot-bootloader

fastboot flash radio radio-crespo-i9020xxki1.img
fastboot reboot-bootloader

fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
fastboot reboot
The only thing missing is a command to erase the sdcard.

You could try fastboot erase /dev/block/vold/179:3
Or boot it up and delete it via android
If they don't work don't lame me I'm a noob xD

You can download the factory images from here > https://developers.google.com/android/nexus/images, you'll need WinRAR, 7zip or similar installed to enable you to extract the files.

if i recall correctly, the command is "fastboot erase media"

Found this
Delete existing apps on Android SD
adb shell rm -r /system/sd/app
adb shell rm -r /system/sd/appprivate
Through Terminal Partition SD card
It will erase everything on your SD card

[Q] Problem flashing recovery.

Hi guys.
I have been trying to root my HTC One S for hours now without any luck.
I have been using this guide,(http://forum.xda-developers.com/showthread.php?t=1583427) and have managed to get all the way to the last step in the "recovery"-section.
But when I try to flash the recovery, this is what I get:
c:\fastboot>fastboot recovery clockwork-touch.img
usage: fastboot [ <option> ] <command>
commands:

reboot reboot device normally

How can this be?
Thanks in advance for your help

Type the following command
c:\fastboot>fastboot recovery recovery clockwork-touch.img

Thanks for your reply, frazzeld.
It didn't work. Sorry. Still the same text coming up.
Maybe there is something wrong with have a managed my fastboot-folder.
Because I am a new member I cant post a picture of my folder :/
But it is set up like this:
(folder)add-ons
(Folder)platforms
Folder)tools
adb
adbWinapi.dll
AVD Manager
clockwork-touch.img
fastboot.exe
SDK Manager
SDK Readme
Unlock-code

Never mind.
It worked after all. Don't know what I did wrong the first 50 times.
Thank you

which clockwork are you trying to install?
Edit: I see you've sorted it now

Are you in fastboot mode? Also the recovery image has to be in the same folder as fastboot.exe is.
To point to the correct folder its "cd"
e.g.
cd c:\fastboot
And the correct command is;
fastboot flash recovery name_of_the_recovery.img
Thats all i can see from what you've posted
edit: too slowwww, glad you got it sorted

From the proper directory. It's not C:\ for everyone... Some have their fastboot.exe in C:\Android and some even C:\Android\platform-tools for example.
Point being, make sure u know where your fastboot.exe is located

[Q] Do I still need a special fastboot.exe for TF300T?

I have 3 HTC devices and 2 TF300T's. I have all the drivers for HTC's devices and TF300T
along with the SDK tools for ICS and JB. The two SDK directories are in my Win 7 Pro x64
PATH so I can run them from any cmd.exe window. I remember seeing a special
version of fastboot for the ASUS tablets and wondered if that was needed for
use of fastboot mode on the TF300T?
If I do, can someone past a download URL for it?
Thanks

If you have got a problem with your adb or fastboot or recovery....it's very simply and faster
use this:
Download this file "fastboot.zip"
Install this file somewhere in one folder which is named "fastboot" on your PC
=> disk C: root
Unzipped this file on the folder "fastboot" and you will find 3 files:
- adb.exe
- AdbWinApi.dll
- fastboot.exe
and when you need to push something by the bootloader, you can use it.
Don't forget to push on this folder the file that you need. For exemple: boot.img or a recovery.img, etc...
The line command is :
Code:
c:\fastboot>
Enter
Code:
c:\fastboot>fastboot flash recovery recovery.img
Enter

Fastboot Driver

I am trying to put a ROM on the TF300. I have Unlocked the tablet and installed the ADB driver. When I boot into recovery and the USB icon it asks for a driver for fastboot. I can't seem to get that anywhere. I have the Android SDK installed and java etc. Where is the driver located? I look in the USB driver folder but its not in their...

If you need just fastboot, use this guide, that you will find in the index for tf300 (General & Dev forums)

[HOW-TO] Flash A/B Treble GSI ROMs without TWRP

Android devices can have different designs, so there is no generic command or set of instructions for flashing a GSI to apply to all devices. Specially for Xperias am i writing this Guides for You. So please read carefully...
1. Ensure that You have the following before You start:
Latest Fastboot Version (Or the used fastboot commands may not work)
A Method for disabling Android Verified Boot (Part of the Guide)
An unlocked Bootloader State (Official Instructions HERE)
To Start:
Download the Basic Package from Google: https://developer.android.com/topic/generic-system-image/releases
Download the AOSP Vendor Package from Sony: https://developer.sony.com/develop/open-devices/downloads/software-binaries
Open up the Zip Files and place the 3 included Images on Your fastboot destination
Boot Your Device into Fastboot:
Code:
Turn off Your Device and hold VolumeUP while connecting via USB to a PC or use ADB to reboot to fastboot
Disable the verified booting (AVB) by flashing vbmeta.img:
Code:
fastboot --disable-verification flash vbmeta vbmeta.img
Flash the Vendor to the Primary A Slot OEM:
Code:
fastboot flash oem_a nameofthesonyoemimage.img
Repeat to flash to the B Slot OEM
Code:
fastboot flash oem_b nameofthesonyoemimage.img
Flash the GSI to the Primary A Slot System:
Code:
fastboot flash system_a system.img
Repeat to flash to the B Slot System
Code:
fastboot flash system_b system.img
Wipe the user data and clear the data from other necessary partitions (for example, user data and system partitions):
Code:
fastboot -w
Reboot:
Code:
fastboot reboot
Additional:
You can use any Android 9+ GSI out of the XDA Forum here: https://forum.xda-developers.com/project-treble/trebleenabled-device-development
To get Magisk/Root; just patch Your actual Kernel with the Magisk Manager App and flash the Boot Image together with the GSI (Example below)
