Are you making sure to set USB Debug Mode?

Settings>Applications>Development>Check "USB Debugging"

Make sure you are set to charge only, not USB Disk Mode.

Also make sure you have rooted first. I used Z4Root from the Market.

Just a couple basic things to check... I do not know of a way personally to do it through the terminal, I used ADB.

Put recovery-RA-GNM-thunderg-1.1.0.img and flash_image on the sdcard. Then open the terminal (you can use terminal emulator, from market) and give the following commands:

$ su

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system

# cat /mnt/sdcard/flash_image > /system/bin/flash_image

# chmod 755 /system/bin/flash_image

# flash_image recovery /mnt/sdcard/recovery-RA-GNM-thunderg-1.1.0.img

# reboot recovery

It looks like you got into fastboot mode. Try flashing the recovery image using fastboot. If it doesn't work, enter emergency mode and flash the original firmware with kdz updater.

:eek:
The image recovery-RA-GNM-thunderg-1.1.0.img has to be flashed on the recovery partition, not on the boot partition. The right command is:

fastboot.exe flash recovery recovery-RA-GNM-thunderg-1.1.0.img

0) remove SDCARD
1) Turn on USB debugging
2) Run KDZ updater
3) select 3GQCT and DIAG mode for connect/flashing
4) Chose fimrware (you can chose from one of original-one)
5) Start flashing
- for few seconds phone will turn itself into emergency mode and flashing will start
- then it shutdown itself
- keep everything as it is and turn it on again
- some message in log will appear and it should be successfully ended (I disconnected it for first time when phone was shutdown and it don't start up correctly after)
6) Sorry for my poor english. Too much verb tenses form me :eek:

My phone cannot go to the regular screen, just Emergency mode now. I am not very sure if it was on USB debugging or not. Is this necessary?

How do I get this KDZ updater and can you tell me which EXE file is the updater?

I have the firmware for my phone, but I am not exactly sure how to do the "Start Flashing" part.

I am a noob with the Optimus One, but I have definitely worked on a Samsung Spica for some time before I got this P500. And the difference is HUGE!

I'm not sure, if KDZ updater will connect to phone if it is in emergency mode. It needs to be tested.

After unpacking of KDZ updater, and running them you will see Start button :)

Is there a good walkthrough for a step-by-step guide to root and install recover on these phones (I have an Optimus T P509 phone, i'm told is the same as the Optimus One)?
