Root [GUIDE]Security Error FIX

travioso said:

were you able to flash the recovery image? it should flash during the backwards screen.. this is specifically for cwm or another recovery being flashed without the bootloader being unlocked. If you tried flashing a rom, you may need to follow this http://androidforums.com/optimus-l9-all-things-root/792689-guide-unbrick-manual-update.html OR this

Also, antdogac, the cmd.exe window that you type flash recovery p4_769.img in should say something along the lines of success.. then reboot manually

Let me tell you this was an adventure. Hopefully it saves someone a day of there life if ever in the same predicament. Found this out over on XDA (forget the exact post) In my case, I flashed CWM without first unlocking the bootloader, only to come to the Security Error screen on reboot. Takes all of 5 minutes to fix. Only requirements are fast boot and the original recovery image (included). I couldn't for the life of me get fastboot to recognize my phone except but using the included start.bat in the fastboot.zip.. What I did exactly was this:

Unzip fastboot.zip to c:\fastboot
make sure fastboot drivers are installed as stated in c:\fastboot\readme.txt

copy p4_769.img c:\fastboot\bin
run cmd.exe as administrator (right click/run as administrator)
goto c:|\fastboot\bin directory then type: fastboot flash recovery p4_769.img (should receive waiting for fastboot device message)
right click c:\fastboot\start.bat and run as administrator
select option 1

follow the instructions it tells you (i actually had to reinstall the drivers again. should pop up as LG P2 (i believe that was the name) this time, install the same way as first time.
the fastboot flash recovery image windows should show its doing something.

let fastboot flash the recovery. Now when you reboot the phone, you should see a dead android guy. turn back off the phone and do a factory reset (hold volume down, home, and power) it should go through the motions of factory resetting.. Everything is erased, phone is like new again.. Now the proud owner of an unbricked phone..

You need to do things in the right order, took me a few tries too but the screen being flipped means you are in fastboot.

You need to run cmd.exe first
run cmd.exe as administrator (right click/run as administrator)
then run
fastboot flash recovery p4_769.img (should receive waiting for fastboot device message)
then start fastboot
right click c:\fastboot\start.bat and run as administrator
select option 1

Once you see the screen flipped the recovery will start and your phone will reboot to the little dead android, then do the reset of the phone, hold vol -, Home, and power till it resets and you will be back where you were.



Happy reset!!
