Installing Custom ROMs on LG Optimus One P500







After having rooted the phone, installed Android SDK and Custom Recovery on your phone, installing a Custom ROM is as easy as copying the ROM file to the root of the SD card and flashing the zip from it.

If you're worried it'll void your warranty, don't be! You can go back to the original LG firmware whenever you wish :  How to flash Original Firmware on the LG Optimus One P500.

If you have any problems with Custom ROMs (installation, usage etc) then post them here : Problems related to Custom ROMs


Here is a list of some great ROMs developed by people at xda forums.



Since all the ROMs have their own kinds of partitions to be created, you can check them at the ROM specific pages.

To flash a custom ROM(make a backup if you want to keep apps, else you can always download them from the market) :
  1. Boot into Custom Recovery
  2. Wipe your cache, dalvik cache, SD card
  3. Make partitions according to the ROM requirement
  4. Wipe first 3 options of wipe menu again
  5. Toggle USB MS and paste the ROM zip file to the root of the SD card
  6. Disable USB MS 
  7. Select 'Flash from zip' option in Custom Recovery menu
  8. Select the ROM file
  9. It'll take sometime and reboot into your new Custom ROM!
Enjoy!

  3. Thnx I installed the Custom Recovery perfectly and did an nandroid backup.
    Now I want to install a custom rom but I see that for most I have to format and partition the flashcard. But Isn't the backup on the flashcard ? If I format the sd card won't my backup be gone ?

  4. Save that backup on your pc. Plus you should only backup apps using Titanium and not the backup from custom recovery. The LG ROM can be downloaded anytime and you can use the titanium backup on that as well.

  5. Ok, had already done that :)
    Does flashing a rom overwrite the custom recovery ?
    Planning to try out void rom this evening.

  6. No, it doesn't overwrite the Custom Recovery. Do post your views about the ROM!

  7. Hi, done flashing, but after a few minutes it says, pico tts stopped, and then android.core stopped.
    Now doesn't appear homepage.It let me access with usb and ask for shell, but he kicks me out after some commands line, cannot recovery.I can interact only with "toggle usb archive" and top window menu.
    Any help appreciated.
    Thanks

  8. Hi again, when the phone have screen locked i can see wallpaper and can unlock it, but when unlocked it shows blackscreen.
    I've tried to reflash it but i can't root it now...

    ReplyDelete
  9. hi again,
    Solved!
    The problem was that i can't see the home and all other menus and the popup in the phone to permit superuser wasn't "popping" (;P) so I can't give permission, i've tried many times, every time i must turn off and on the phone and restart adb, if u encounter the same problem try rotate many times the phone while asking for root, if the countdown reach "0" then u'll be kicked out from shell and have to restart all.
    Now i've loaded the basic rom with jit enable, Megatron doesn't fit for me :(
    Thank again.

  13. Sorry.. I got it myself from the XDA, Thanks.

  14. yup u got me! I am from erodov, Finally in prime v2 !! I was working on this from last night, No sleep , took my time did everything one by one . I was in 2.2.1, so i downgraded to 10B then rooted , started the custom ROM process and finally completed !!

    God like your really like god for LG optimus one. Its great peace of work you have done here ! Any layman should get it right! Please continue your work !!

    Now i am on prime v2, In need somemore tips on customization of ROM, example how to increase the OC? etc ..- Gatsri

  15. To increase the CPU speed, it'd require a Custom Kernel. Prime v2 does not support custom kernels. I used Prime v2 and my main reason for switching to void was the overclocking kernel it has bundled in it. I'll write up in a few days about the void ROM and an easy step by step guide to flash it onto your Optimus One.

    ReplyDelete
  16. Thanks Godlike!
    Just flashed to Prime v2 and will try it out for the next couple of days!
    Will wait for your writeup on void ROM before I proceed! :D

    there sud be a fourth link saying "Incase you havent taken a backup of your present ROM" and give a tutorial on how to..

    that would be good..

    ReplyDelete
  18. Do you know is there any reason why after installing Prime v2 and it worked for a day or so then the phone will lock up and now it won't start at all. Just come up with LG logo and then died. I cannot turn it on again. Do you think it would be a faulty phone?
