I doubt that's possible

I think you can only flash official roms with kdz because custom roms needs SD card to use "flash zip from sdcard" in the recovery.

There must be a way for flashing ROM through adb.

there is, basically look up how to copy files from PC to phone using adb, and just copy everything in the ROM onto the / (root) of your phone, as all flashable zips do is copy the stuff from your sd card onto your phone

Use Android Commander version 0.7.9.10 by PanPiotr. It has a option to flash your phone under device menu. I have never used it so I don't know if it will work, but it might be worth a try. http://androidcommander.com/ here is the link for the software It is a very powerful application I would recommend to any andriod user, good luck I would like to know if it works for you. All of the features I have used work perfect.

I only understoood that you flashed.stock firmware using kdz and have no sd, so steps are as follows:
1.root optimus 1 using superoneclick
2.flash cwm using adb
3.reboot in recovery
4.mount /system
5.then format /system
6.flash rom using adb
or
just copy paste files in /system of your phone
I mean the files which are in zip of custom rom

How to Flash a ROM Without an SD Card

This is for all those who don't have a working sdcard, sdcard slot, etc. but want still to flash a new rom

Prerequisites:

1. Flash an Amon_RA recovery if you're using Clockwork
2. Access to a computer that had AndroidSDK tools on it - you'll be using ADB
3. Put whichever ROM.zip you want to flash in your android-sdk\tools folder - I would rename it to something simple. (My example which I'll be using for this tut is: C:\AndroidSDK\toosl\ROM.zip)

Directions:

1. Reboot into the Amon_RA recovery
2. Wipe data/factory reset, cache, and dalvik via the recovery menu
3. Open up cmd/terminal on your computer
4. Navigate to your android-sdk\tools directory
5. Enter the following in cmd/terminal:
   

   adb shell
   mount data

6. *wait a second or two* You may or may not get the "/ #" line returned.
7. Despite what happens press "Ctrl+C" to break the command and get back to the standard AndroidSDK\tools> directory
8. Enter the following in cmd/terminal:
   (replace "ROM.zip" with the name you're using)
   

   adb push ./ROM.zip /data/

   *this will take anywhere from 30sec to a min depending on the rom.zip size*
9. Then we do this in cmd:
   

   adb shell
   recovery --update_package=DATA:ROM.zip

10. Wait for it to finish flashing/updating
11. Reboot
12. ENJOY

Brief rundown of what we just did:

• Wiped /data/ to free up space for the zip
• Put our ROM.zip onto the /data/ partition since we don't have an SD Card to work with.
• Told the recovery to flash from our /data/ partition instead of /sdcard/

.......

is there a way to toggle signature verification through adb? My sd card slot is not working and i am trying to flash back to stock to go to sprint for repair but when I run the command and reboot into recover it says signature failed and then I can not pick the update.zip i put in the data partition.
