[How To] Install CyanogenMod 7.2 / Android Gingerbread 2.3.7 on LG Optimus One P500

Posted on May 12, 2011 by Manas

Last updated on 12-Oct-2011
The LG Optimus One P500 has got the scheduled Gingerbread 2.3 update. But as per the feedback of the users, the release has some bugs and the performance is not that good.

Over the past few months I have tried out almost all the custom ROM’s available for LG Optimus One P500 but have found CyanogenMod 7.2 running on Gingerbread 2.3.7 to be the best one for performance, gaming and battery backup. While it has some minor bugs as of now, I have been using it for the past four months and have not faced any issues.

Pre-requisites before proceeding are you must have already rooted your phone and installed custom recovery on it. Also it is required that you are using the new baseband on your phone.

Download the latest CM 7.2 nightly available for LG Optimus One from here.
Shut down your phone and boot into Recovery by pressing the Volume Down, Home and Power buttons together. You can move through the options using the volume up/down keys. Use the Search button to select the option.
In the recovery menu, select Backup and Restore, then select the ‘Backup’ option. What this will do is backup your current ROM on your SD card, if something goes wrong while flashing the new ROM you can simply boot into recovery and restore your previous ROM using the Restore option.
Connect the phone to your computer and inside Recovery main menu click the option ‘Mounts and Storage Menu’ and then ‘Mount USB Storage’. This will unmount the SD card so that you can see it in your computer. Backup everything from your SD Card. Safely remove the SD card from computer and then click on unmount from recovery to mount the SD card back in phone.
Though it is not a necessity for this ROM, I would suggest partitioning your SD card to create swap and ext partitions. The ext partition will come in use if you want to install apps onto your SD card later. This is different from what you see in Froyo versions of Move to SD option. Partitioning will format your SD card, so make sure you backup your SD card as mentioned in Step 4.
Go back to the recovery menu again and select ‘Advanced’ and then ‘Partition SD Card’. Then select ‘Partition SD’. Create a swap partition of size 0M and ext partition of size 512M.
Toggle USB from recovery again in the same way as Step 4. Inside the SDcard create a folder named ‘AAA’ and copy the ROM you downloaded in Step 1 into the folder ‘AAA’ on your SDCard. Once done, eject the SD card and toggle USB again to mount the SD Card in the phone again.
Go to the main recovery menu and follow the below steps one after another to wipe data, cache and system.

‘Wipe Data/Factory Reset’ –> Yes
‘Mounts and Storage’ –> Format /system –> Yes.
‘Advanced’ –> Wipe Dalvik cache –> Yes

The final step is to go to select Install Zip from SD Card –> choose zip from sdcard and then select the zip file you copied in Step 7.

Sit back and relax while the zip is flashed. Once recovery shows that flashing is complete, reboot phone from recovery. The first boot will take quite some time.

Enjoy official CyanogenMod 7.2 / Android Gingerbread 2.3.7 on your LG Optimus One P500.

Update:

The ROM does pre-install Android Market or any Google Applications. Download GAPPS zip from ROM Manager or from here (Install from Recovery, Wipe Cache & Dalvik cache and install zip).

ROM Manager –> Download ROM –> Google Apps –> 20110828 Universal

Install from ROM Manager. Select only ‘Wipe Dalvik Cache’ when shown the options in ROM Manager.

The phone will ask you for the Google account you want to phone to be linked to. You can then see Android Market in your app drawer. Search and install the Google Applications you want.

For anyone wondering: this ABSOLUTELY works if you have a stock Optimus One from Koodo with old 2.2.1 installed on it. Do not – DO NOT! – install the recent so called upgrade available in your LG Suite. Use SMS Backup + to backup your SMS messages and Call Log, then export all your contacts to a CSV or something. Then follow the 3 guides noted above for Rooting, Custom Recovery and then finally the CM 7.1 (GB 2.3.7). My old p500h is like a new girl all over again…and she screams! Thank you SO MUCH to the writer. I waded thru the XDA forums and was ready to give up because of all the technical jargon, it looked quite daunting. Your guide had me up and running in 30 minutes flat. Amazing!!

And to the people above who asked about if they can just flash over their existing 2.3 the answer is NO afaik. Without getting to technical, if you didn’t get the so-called Gingerbread update from your mobile provider OTA or thru the LG update tool, this guide above is for you. In other words, you were running Froyo 2.2.1 or earlier before. If you’ve already updated to the the latest software your LG tool has to offer, ie 2.3, this will not work without some extra work to do with old vs new basebands. Don’t ask me, have no clue, but I came from the old one and was fine.

Those mouthing off that this doesn’t work:

1. If you did any further research prior to installing CM7, you would’ve known that installing over 2.3.3 requires the new baseband (basically cellular network drivers). The new baseband is NOT available in the unofficial CM7 port yet. But you didn’t do your homework, so now you’ve got a fancy toy with no network. Good job.

2. If it’s the worst guide on the internet, stop complaining, put the dummy back in then go find another guide.

I installed cyano 7.1 ok, but i had problems with my telephony, as i could not use my sim card (could no unlock it). So I just installed cyanogenmod 7.2 with the same steps you mentioned, and it was ok (except my google services, that means my contacts, market etc, where i used Titanium Backup, to bring them back.
The only problem it remains is the android market app. As soon i try to download something from the market, i get an error saying “com.android.vending stopped, try again”. I tried a lot (older versions, clear cache, fix permissions… ) but nothing. Any ideas?

I am confused. In the guide, it was said the new baseband is required, but in the comment, it was said I should keep the old baseband. I am running 2.3.3 with version V20a, can I install this? Can someone clarify this.

Lester, go ahead. This is for the new baseband now.

omadegbo on March 4, 2012 at 5:36 am said:

@Luke, if you were using default lg android before this steps, download the new baseland (P500-v20G-baseband) and follow the instructions. After that, you should be okay.

I had similar problem, I went back stock rom which was version 2.2. Changed my baseband using P500-v20G-baseband and came back to follow the steps to install cm 7.2. Everything works now except for the android market. Hope this helps.

omadegbo on March 4, 2012 at 12:48 pm said:

@manas thanks for a great tutorial. I have the cm 7.2 working on LG P500 and its pretty fast compared to the stock rom!

The only glitch though is my contacts and previous sms and apps.
Is it possible for me to restore my contacts and apps from the backup I did in step 4?

Hey Manas,
Awesome job buddy. Must say this is the best, most lucid and comprehensive guide there is to upgrade to cyanogenmod. It was so easy following the guide, the way you have put it up is commendable, very user friendly.
I had a few issues like no signal after the installation however on going through the comments, the solution already existed. The baseband tweak did it for me.
Awesome work dude.. sincerely appreciated!
