Hi everyone,i am really happy in bringing out this how-to tutorial on updating LG optimus one (P500) to Jelly bean 4.1.1 isong Cyanogen Mod 10.
CM10 has been ported over to P500 by XDA member Rashed97 . Make sure you have the following pre-requisites,before reading the tutorial further :
- Root your device – Follow instructions from here.
- Install custom recovery - Follow instructions from here.
- Get the CM10 rom file for optimus one from here. (thanks Rashed97) [August 25th 2012,updated]
What works
- Touchscreen
- Wifi
- Bluetooth
- 3G
- sensors
- All audio
- Full H/W Acceleration
- GAPPS
- Native apps
- Most project butter related enhancements
- Airplane mode
What Doesn’t work
- Camera
- Google now voice
- Screen on/off animation
As you can see from above,the rom is still under development stage,but you can still flash to get a jelly bean taste on P500. Also XDA users have reported battery drain with the rom.
Ok,that’s all you need to have and know before begining with the tutorial.Let’s begin :
- Connect your phone to PC using USB cable.
- Now place the downloaded rom file on root of your SD card. (if you have downloaded the rom file in mobile,then you can use any file manager to move the file to the root of your SD card).
- Now disconnect your phone from PC.
- Before going any further,make sure your phone is charged to atleast 50%.
- Turn off your phone
- Boot into recovery : press and hold the home+volume down+power button simultaneously.
- Once you are in recovery menu,select Backup/restore and then do a Nand backup.Doing this will backup your entire current rom plus your applications.Use the backup file to restore your current rom and apps,incase if something goes wrong while flashing.
- Alternatively you can backup your applications by using titanium backup (root only version) and also contacts and sms using super contact backup (search in market).
- Now go back to recovery main menu and do a full wipe by selecting the following :
- Wipe Data/Factory reset
- Wipe Cache
- Wipe dalvik-cache - After doing this go back to the recovery main menu and select install zip from sd card and browse to the rom file which earlier you saved in the root of your sd card.
- Select the file to begin the flash process.Sit back and have some water.
- After the flash process has been completed successfully,go back to recovery main menu and select reboot.
- That’s all !!! After reboot you can enjoy the goodness of Jelly bean on Optimus One (P500).
To have gmail,play store and other GAPPS flash the GAPPS file from here in the recovery (after the first reboot).
This CM10 rom works only with new baseband.If wifi,data, or network is not working then flash new baseband.Follow instructions form this thread.

Kudos to you Pradeep tahnks soo much worked great, the only issue i have with this is IT LOOKS SO PIXELATED AND DISGUSTING but other then that it’s absolutely perfect. +1
Yes its pixelated because the rom is still in the development stage.
Also,i have put an updated rom file dated 25th august,check that out.
Pradeep Farkya recently posted..Samsung Galaxy Camera,runs on Jelly Bean,21x optical zoom
yup i will check that out, where can i go to get the latest updates for the ROM and when will it be updated again? (Approximately)
I will update the article from time to time.No one has to worry about that
One last thing; what is new in the update and do i have to flash everything again and reinstall the ROM? I want to know whether it is worth doing that again if i have to.
Thanks in advance.
yes,you need to flash everything again.To backup apps you can use applications like titanium backup.
To keep a track of when the file has been updated,look for the date which has been mentioned in the bracket
has the rom been fixed with camera and pixel issued or its still the same?
Thanks
I actually found that the rom made my phone overheat and it got bricked :’(
Any advice people?
