    I managed to do a nandroid backup, but I cannot restore.

    I get an error message, something with ADB. Sorry I haven't kept in my mind the entire sequence.

    Any help would be apreciated.

    Go to market and download Terminal Emulator.

    After that launch it and type SU. Click Allow. After that type all the commands listed above.

    Good luck !

    My Lg Optimus Ones will not boot. Might this be able to fix the problem?

    I have no back ups as phone died whiling trying to do first back up.

    I am guessing the emulator lets you type commands on the phone??

    If so it is probably not what I need.

    This tutorial is easily the most frustrating thing i've ever had to follow. I'm typing these comands into the terminal emulator with no errors, yet it just doesn't work.

    I have the two image files on my SD card, I rooted with z4root before that, and it doesn't work.

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

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

    # chmod 755 /system/bin/flash_image

    # mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak

    Here it says now, failed on this, no such file or directory. But the first time I did it, this worked.

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

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

    I did this, then it said it failed part way through because something was missing or corrupt, then I went back to start again and it doesn't work now. what the hell.

    # reboot recovery

    followed all the steps mentioned. when i hit

    # reboot recovery

    my phone re boots normally and all the data is wiped off and i get the LG P500 basic 1st time set up screen! can anyone tell what went wrong?

    EDIT: While using the ADB commands i had mounted my SD card which i guess caused the problem.

    Update: Now it either won't let me because of a lack of a signature, or no update script

    Quoted from 1st post

    "Note this recovery and the one for the LG Vortex have a service that instantly reboots out of recovery once you load it & I disabled it and thats why you get a E: "Bad Boot Message" on inital startup. Its completely fine."

    Requires custom scripts and or rom. Look for custom roms available for device.

    Thats stock recovery. You didn't flash custom recovery properly or didnt remove the install-recovery.sh.

    Hello,

    I want to make a backup of my current default rom before messing around with custom ones and deleting default system apps. That flash_image and the recovery .img you provided will simply enable me to get into debugging mode from where I can make a backup of my current default rom, right? It will not flash my rom with any custom roms or will it? Also, afterwards how can I restore my default debugging mode if I need to reclaim my cell phone warranty or something?

    If you could explain step-by-step what all of those commands do it would be nice also. I'd like to understand the whole procedure before trying this out.

    Thanks!

    # mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
    # cat /sdcard/flash_image > /system/bin/flash_image
    /sdcard/flash_image: invalid length

    It worked beautifully. I am now the proud owner of an Optimus T P509 rooted and custom ROM'd. I installed Amber Home V 1.1 on it. Thanks guys!:D

    I too work well in my LGP500, I only had a small problem with some commands enter spaces, but now is ok. I too installed Amber Home V1.1 and work ok. Thanks.:)

    some question more,
    when I download an application, where default is saved, in phone memory or partition ext3 Memory Card (512 mb)?
    Can I know how much memory as ext3 microsd card I am using. :eek:

    Fabulous method! I would suggest adding that one needs to unzip the necessary files that you provide: the recovery image and the flash_zip. I would also clarify that if the install-recovery.sh script is not found its still a go for those that aren't down with linuz and his CLI speak. Thanks!
