Guides

In the beginning, there was the Android device and it was good. Then came the hackers and modified it, and it was good. Then came the end-user and all kinds of hell broke lose. So here is a guide that will walk you through step-by-step into modifying the LG Optimus Me. It has also been translated into Spanish (ES-LA), Portuguese (PT-BR). Help translating into any other language would be great!

The following are the highlights of the guides and are placed here for referential purposes.

Rooting Process

Gingerbreak

Exploit created by The Android Exploid Crew and wrapped in an APK by Chainfire. Originally created for Gingerbread OS, but also works on this device's Froyo. This Process only works if the official LG update for this phone hasn't been applied where the exploit is patched. Original thread.

Installation

  • Make sure USB debugging is enabled and drivers installed
  • Make sure you have an SD card (formatted and) inserted
  • Get the APK on the phone somehow (download from original thread to SD card does just fine), and install it (make sure Unknown sources is enabled)
  • Open the APK, press the root button
  • Wait a few minutes. If there are no problems, the device will reboot (note that the reboot itself can take like 10 minutes due to cache wipe)
  • Make sure the Superuser app is install and working
  • Optional: Install BusyBox from Market (I personally prefer the stericsson installer)
  • Optional: Uninstall GingerBreak, you don't need it on your phone anymore

SuperOneClick

Application created by CLShortFuse that works with bits from the Android SDK. Contains most of (if not all) the exploits for various devices. You can check more detail on the Original thread.

Usage

  • Make sure USB debugging is enabled and drivers installed
  • Connect the phone to PC
  • Run the application
  • Press Root button and wait a couple minutes
  • Make sure the Superuser app is install and working

You can check more details in this video.

LG P350 Toolkit

Tool created by antdking. At the time is a work in progress. This tool has been created to root, install recovery, and unroot the phone. You can follow development at the original thread.

Recovery

While Official ClockworkMOD recovery does exist for this device, right now, it has a very damaging bug, causing the phone to boot into Fastboot mode, hence effectively soft bricking the phone.

Proof of the bug September 2012

"I was only trying to install CM 7.2, then I used ROM Manager to install CWM, I was very excited. I clicked 'Reboot to Recovery' and the little thing rebooted, but then this black screen with white text appeared. The text had the word 'fastboot' in it. I was shocked and like 'What is this?' Two days later, I spent $12 on phone repair. I started to hate LG big time, but I started to logically think it couldve been my fault." -SammyDroidWIz, at time of incident named OptimusLove

List Of Recoveries

Most of the recoveries for the device is unofficial but is always ready for daily use. Here is the list of recoveries for the device.

For starters who are installing the custom recovery for the first time we would recommend you to go with AmonRA for those who have installed it and had experience with recoveries can go for CWM Recoveries. CWM Recoveries are on of the popular recoveries it has many features comapred to AmonRA. For those who had experience with both CWM and AmonRA can bravely go for the next leap TWRP Touch recovery.It is next big revolution in recoveries and is now the number one recovery. Unlike the CWM Touch where you can navigate only through four buttons on the screen may find this recovery a delight as it is fully touch based and also has customized themes for different looks.

Manual Installation

  • Download zip file and extract recovery.img and flash_image
  • Copy both files to the SD Card (either with a file manager or with ADB)
adb push recovery.img /sdcard/
adb push flash_image /sdcard/
  • Login, remount /system in rw mode and "install" flash_image utility
adb shell
$ su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# sync
# reboot
  • Reboot is recommended because virtual memory may run out, but you may continue without doing it. If device has been rebooted, follow from the beginning, otherwise start from the second command.
adb shell
$ su
# flash_image recovery /sdcard/recovery.img
# sync
# reboot recovery

If all was done correctly, a menu should appear.

Zip-file Installation

IMPORTANT: This method is only if a previous recovery has been installed. If not, follow the Manual Installation process.

  • Download zip file
  • Copy zip file into SD card (if not downloaded from phone itself)
  • Reboot into recovery
  • Flash zip file
  • Reboot system (Or Reboot into Recovery if you have previously installed CWM to confirm new Recovery has been installed)

ROMs

CyanogenMod

CyanogenMod is an aftermarket firmware for a number of cell phones based on the open-source Android operating system. It offers features not found in the official Android based firmwares of vendors of these cell phones. The LG P350 has a sparsely active official CM7 Support. Meanwhile unofficial CM9 and CM10 ports have emerged. CM7, CM9, CM10, CM10.1

Based-on

Here's a list of ROM most of them (if not all) based-on CyanogenMod 7 ROM.

Troubleshooting

Softbrick Easy Tools

If you stuck on fastboot mode you can unbrick your phone easily with SET! Read more on Official Page

This tool will solve the fastboot stuck mobile (softbrick)!

You can root/unroot and flash different recoveries.

Every thing is in build nothing to do new to install just tools from this site is enough

Fastboot

Definition: Fastboot is a protocol used to update the flash filesystem in Android devices from a host over USB. It allows flashing of unsigned partition images.
Once taken that question out of the way, let's continue...

So, a partition got damaged (either by flashing a wrong image or playing with the partitions with ADB) and phone is fastboot-bricked. DO NOT PANIC! That is step one! Do not blame the developers nor anybody else, remember this is done at your own risk. That is step two.

Moving on... You messed around with a wrong Recovery image and now you have the screen all black with some white text saying:

fastboot mode started
udc_start()

I really hope you have followed this guide (or at least read it) and know by now that you'll be needing:

  1. Drivers installed
  2. Android SDK (all tools installed)
  3. AmonRA-GNM Recovery (Download and extract .zip folder)

Expecting you have all these installed (and PC rebooted) and correct image acquired proceed with the following steps:

  • Connect the phone to PC with USB Cable (You will know that it is detected if you see the the lines "suspend", "reset" and whatnot on the phone's screen.)
  • Open command prompt and change directory (cd) to where fastboot is located (In Windows, generally it should be at C:\Program Files\Android\android-sdk\platform-tools\) and type the following commands:
fastboot erase recovery
fastboot flash recovery /path/to/<recovery>.img
fastboot reboot

This guide takes Recovery partition for example, but this steps can be followed for other partitions too. For other partitions use the .img files in your Backup folder

If all went well, it should reboot normally. If not, go back and do this all over again. If still stuck here, go to next section.


KDZ Updater

In case of softbricking, there is one last line of defense, KDZ Updater. This application allows users to reload official LG firmware into the phone.

Usage:

  • Connect the phone with USB Debugging activated
  • IMPORTANT: Disable the Virtual USB Modem device from Windows Device Manager. Omit this step and the device may brick in the upgrade process.
  • Run the application in Administrator mode (only required on Windows Vista / 7).
  • In the Type drop-down list select 3GQCT and in PhoneMode, DIAG. Where it says Version, will appear the version that is installed on the phone.
  • Select the KDZ file to install by clicking on the button with the folder icon. Preferably save the file KDZ in the root of the hard drive as there will be little chance for error when reading the file.
  • Press the button “Launch Software Update”. The phone will reboot into Emergency Mode. This is normal.
  • Pray all you know and go for a cup of tea. The process takes about 8 to 10 minutes.
  • If all went well, the phone will turn off and the program displays a line that says = FINISHED =.
  • To start, first go into recovery mode by pressing the following buttons: Vol- & Power. This will make any old or unnecessary information to be removed. The phone will reboot into the system normally.
