In this article we will show and tell you how to flash your LG Optimus One (P500) using Custom Recovery Menu ( AmonRA) thereby updating your device to Android versions 2.3.7.

And so, at the beginning I will explain what it is Custom Recovery Menu. This is a specialized menu that allows you to use a package of very useful utilities. After installing it on the phone, it will replace the standard data reset function (Hard reset, wipe), therefore it is called in the same way. After Custom Recovery Menu will be installed, it is highly undesirable to touch “Settings=>Privacy=>Reset settings”.

Custom Recovery Menu is a very important and basic utility for flashing your device; it will also come in handy if you are going to flash your device several times and update it with unofficial firmware, kernels, themes, etc.

Besides that Custom Recovery Menu makes it possible to flash the phone with files in the format "ZIP", it also has many functions, including resuscitation of the device in the event of a breakdown due to the firmware (for example, errors in the kernel or a non-working patch). With its help, you can make a backup of the system in case something goes wrong, everything can be returned in a couple of clicks. You can also format the flash card in your phone and use the device as a card reader.

To enter the menu Custom Recovery Just turn off the phone and hold down 3 buttons HOME (house) + Volume down + Power. Navigation through the menu is carried out using the volume buttons; they serve to switch between menu items; the “Return” button will return to the previous menu or cancel some action. The “Menu” button is used to confirm actions.

Turn off all antiviruses and firewalls.
Download the utility itself.
We connect the phone to the computer when USB help- cable.
We enable USB debugging, this is done as follows: Settings => Applications => Additional options => USB debugging. We put a tick here.
Unpack the archive with the utility to any location on your computer.
In the ADB folder, click on the file cmd.exe (there will be 2 of them, for XP and for 7 (vist)).
In the appeared command line Enter the following in turn after each line and press Enter:

adb devices
adb shell
echo 1 > /data/local/lge_adb.conf

Manually reboot the phone (Turn it off and on).
Next, go to the onSDCard folder and, as the name suggests, drop it onto the SD card.
We connect the phone to the computer via USB again (the “USB storage” mode must be turned off)12. We enable USB debugging as described above (Settings => Applications => Additional options => USB debugging. Check the box here).
Again go to the ADB folder and click on the file cmd.exe
And just as before, we drive in these lines one by one:

You don’t have to write commands manually; you can simply copy and paste them, this is done using the mouse.

adb devices
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
flash_image recovery /sdcard/LG-P500.RU-recovery-2.2.1-GNM.img
reboot recovery

If everything is done as needed, the device will reboot in recovery mode.

After that, download the archive and put it on the flash card, after which we live by selecting it in the menu Flash zip from Sdcard.

Now let's move on to flashing the firmware of the device itself after what was done earlier, this is done quite simply:

Download the latest one on this moment and the most stable Official build of CyanogenMod 7 (nightly,RC).
We throw it at the root of the SD card. (do not unpack the archive).
Reboot the device into Recovery mode(with the phone turned off, press 3 buttons at once, volume down + HOME (house) + power button).
We perform such actions wipe data/factory reset, mount and storage => format /system And advanced => Wipe Dalvik Cache.
In point install zip from sdcard => choose zip from sdcard, select the previously downloaded firmware format "ZIP".
Next we go to this address install zip from sdcard => choose zip from sdcard, and click on file gapps-gb-20110828-signed.zip
Then we reboot the system using the menu item reboot system now We are waiting for loading (it will take longer than usual)
