Brave users might proceed at their own risk. However if anyone knows the correct instructions they are welcome to edit the template or ping the moderators on the CM wiki IRC channel. Reason: There are no instructions to install recovery.

This guide will walk you through the process of taking the Optimus One from stock to having a custom recovery image and the ability to flash the latest version of CyanogenMod.

Note: DISCLAIMER

Modifying or replacing your device's software may void your device's warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.








Installing CyanogenMod from recovery

Note:

Some devices do not have removable SD cards. Regardless, there should still be a partition on the device named "/sdcard" that can be used for flashing purposes, even though the contents of /sdcard may actually be in internal storage.

  1. Download the prebuilt release of CyanogenMod you wish to install. (Or if you've built CM yourself, look in the $OUT directory for the .zip.)
    Optional: Download any supplemental 3rd-party applications packages for the device you wish to use.
  2. Place the CyanogenMod rom .zip file on the root of the SD card using adb:
    • Transfer your file(s): adb push YOURROMZIP.zip /sdcard/
      • If you boot directly to recovery and have an internal sdcard, you may need to run adb shell mount /sdcard or mount data through the recovery menu before transferring.
      • If you see "error: device not found" there is likely a driver issue on the PC.
      • If you see "error: insufficient permissions for device", try "adb kill-server" and then run "adb devices" to see if the device is attached.
      • On some devices, the zip file can be copied to the device using standard USB Mass Storage or MTP support. Boot the device normally and transfer the file to it.
    Optional: Place any supplemental packages (e.g. Google Apps[1] or kernel) .zip file(s) on the root of the SD card.
  3. Boot to recovery mode on the device by holding Volume Down + Power + Home.
  4. Once the device boots into the ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm your selection, although for some devices the power button is used as a "back" button to go up one level, in which case the home button is used to confirm the selection.
    Optional/Recommended: Select backup and restore to create a backup of the current installation on the device. If this option is missing, it's likely because the stock ROM has overwritten your custom recovery on boot.
  5. Select the option to wipe data/factory reset.
  6. Select install zip from sdcard.
  7. Select choose zip from sdcard.
  8. Select the CyanogenMod file you placed on the sdcard. You will then need to then confirm that you do wish to flash this file.
    Optional: Install any additional packages you wish using the same method.
  9. Once the installation has finished, return back to the main menu, and select the reboot system now option. The device should now boot into CyanogenMod.

  1. Go to Google Play Store
  2. Install "ClockworkMod ROM Manager"
  3. Follow instructions when you open it
  4. Confirm your model and select Clockwork Recovery mode
  5. Wait for download to complete

Non-rooted devices

It is easy to root this device, so root the device before trying to install cyanogenmod.

Use SuperOneClick : http://forum.xda-developers.com/showthread.php?t=803682

SuperOneClick can easily root LG P500H phones from Telus Canada running Android 2.3.1 and Android 2.3.3

More on Recovery Mode Install

In some cases (encountered at least with LG P500 with Android 2.2.1 and 2.3.3), the current (2014) ROM Manager does not install the ClockworkMod Recovery image correctly. The manager does not report any error, however, on attempt to boot ClockworkMod Recovery, stock recovery is displayed and factory reset takes place afterwards (behavior described e.g. here http://androidforums.com/optimus-one-all-things-root/465761-clockwork-mod-reboot-into-recovery-factory-resets-phone.html). This issue can be fixed using the LGMDP tool (process described here http://forum.xda-developers.com/showthread.php?t=1318750), it might also be necessary to try multiple versions of the ClockworkMod Recovery images.

Another issue to pay attention to is the phone baseband version (especially if the installed CyanogenMod image does not connect to the mobile network at all).

Accessing Recovery Mode

Easy GUI Option

  1. Open ROM Manager
  2. Select 'Reboot into Recovery'
  3. Press 'OK'

Key Combination

  1. Power off phone
  2. Press and hold VOLUME DOWN + HOME + Power until you see LG Logo



Troubleshooting

VOLUME DOWN + HOME + POWER just resets the phone

If you enter the key combination and you see a white box, yellow arrow and a green droid, this means that you have not installed ClockworkMod Recovery mode. Install ClockworkMod Recovery mode and try again

Backup failed 'error while making a backup image of /sdcard/.android_secure

If you see an error running a backup of your phone and it says 'error while making a backup image of [ insert folder name here ]', you do not have enough free space on your sd card. Free up space on your SD card and try again

Here is a page that talks about => .android_secure

  1. Go back into recovery mode
  2. Wipe/factory reset your phone
  3. Reinstall the Cyanogenmod image


I don't have Android Market/Google Play Store anymore

To get Google Play Store, you must install Google Apps. Download the ZIP file to your sd card, reboot into Recovery Mode and install the ZIP. It'll add Google Play Store to your install. This also installs GMail and some other basic Google apps.
