Complete guide for Koodo 2.2.1 Froyo to CyanogenMod 7 (Gingerbread)
Requirements:
Stock MicroSD Card will work
A working MicroSD Card reader on your computer. I had a MicroSD adapter laying around that turns my MicroSD into a SD card.
Time - approx 3 hours or more
Setup 0: Preparing you and your computer for the rooting process
- An apk is like an exe file. It's an installation file for android.
- Make sure you have USB debugging enabled (Settings - Applications - Development - check off "USB Debugging")
Installing Drivers for your computer:
Download and install:
http://csmg.lgmobile.com:9002/client...2CAppSetup.exe
Run LGMobile update
In the application menu, click "Customer Support" and then "Application, Manual and USB Driver Download"
Enter your IMEI and search. Then download all the listed files
Run LGUnitedMobileDriver_S4981MAN32AP22_ML_WHQL_Ver_3. 2 from the location you downloaded it in the above step.
Note: If your PC is having problems recognizing your phone, try using a different MicroSD cable. If you have Windows 7, uninstall the drivers and let windows install the drivers for you automatically or through windows update.
Step 1:
Prepare yourself. You will not brick your phone. It's almost impossible to brick your phone if you follow the directions.
Step 2:
So, since android 2.2.1 is not rootable on Optimus One, I had to downgrade to android 2.2. I found a link to a Telus version of P500h that is android 2.2 at the following link
Download:
http://csmg.lgmobile.com:9002/swdata...00/V10G_00.kdz
Now download KDZ updater from here and uncompress it
KDZ_FW_UPD_EN.7z
Uncompress downloaded file
Install msxml.msi from the uncompressed directory
Conect your device (do not turn on disk storage) and run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT
Select PhoneMode : DIAG
In KDZ file : Choose the ROM file you downloaded (V10G_00.kdz file)
Press Launch software update and wait (It will be 10 minutes or so). In your phone it will appear "Emergency mode". Wait until it reboots.
Step 3: Rooting
Now I used "z4root" to permanently root. It was super easy. z4root is NOT in the market anymore so you need to sideload it onto your SD storage with your computer's sd card reader, then install it with any apk manager (Astro manager, available in the market). Make sure you have Third party installation checked (Go to Settings --> Applications --> and check off "Unknown Sources")
Download z4root.apk:
z4root.1.3.0.apk. Your antivirus might report that it's a virus, but it's not. It's a false positive. You can also download one from a source you prefer or you can download z4root from the developer's own thread here. Both of them are the same.
Put the apk in your sd card somewhere and install it with the file manager you downloaded from the market
Run z4root and root your phone. It will automatically reboot after
After reboot, check if you have the app "Superuser" installed. If you don't see it, go to the market and install it.
Step 4:
At this time you have a rooted 2.2 Froyo phone, but we want to go to Cyanogen7, which is awesome
Now we will do the following:
1. Install custom Recovery
Download this, unzip and copy both files to your sd card root through the phone's usb drive support -
flash_image&recovery-RA-GNM-thunderg-1.1.0.img.zip
Go to the market, download "Terminal Emulator"
Run the following commands from your phone on the terminal
Code:
su root
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 ("file not found" error? Ignore and skip to the next command..)
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img
reboot recovery
Phone should reboot into recovery mode. If it doesn't, shut down the phone. Hold the volume down key, home key and press the power on button simultaneously. Release them when you see the LG screen and you should boot into the recovery menu
2. Partition SD-Card
Because this ROM uses Apps2sd you need an ext3 partition on your sd-card.
Make backup of sd-card (you may need to boot back into the phone and copy the sd card files over to your pc)
boot into recovery (HOME+VolumeDown+Power)
select "Partition sdcard"
select "Partition SD" and confirm with menu
set swapsize to 0 with volume-down (no Swap-Partition) confirm with menu
create EXT-Partition with 512MB (confirm with menu)
after partitioning select "SD:ext2 to ext3" and convert ext2 to ext3
restore backup of your sd-card from your computer (just copy the files over to the sd card)
3. Wipe
For first installation of this ROM you should do a full wipe:
boot into recovery (HOME+VolumeDown+Power)
select "Wipe"
select"Wipe data/factory reset"
select "Wipe cache"
select "Wipe Dalvik-cache"
select "Wipe SD:ext partition"
back to main menu to flash ROM
4. Install ROM
Remove sd card from phone and put it into your computer's sd card reader.
Download 3 files and put them into your sd card root. DO NOT EXtract ANY OF THESE ZIP FILES. Put them as it is.
cyanogen_thunderg-ota-eng.mik.zip
gapps-gb-20110120-signed.zip
Debug-FormatSYSTEM.zip
Put sd card back into your phone
Next:
boot into recovery (HOME+VolumeDown+Power)
select "Flash zip from sdcard"
select Debug-FormatSYSTEM from list
confirm with menu
select "Flash zip from sdcard"
select cyanogen_thunderg-ota-eng.mik from list
confirm with menu
select "Flash zip from sdcard"
select gapps-gb-20110120-signed from list
confirm with menu
reboot phone from menu
DONE.
