@royal.tarun - Thanks for the Rom. Why don't u consider the development based on CM7 ?
happy to see that someone has at least seen my post.
Except you and Sam others have just ingored it.
Developing on CM7 would be better ?
which one would you suggest.
@ pratik.
Basically on a windows machine you download kdz updater and uncompress it as it is a zip file.
Download from here.
This is what I did on an xp laptop.
I had to down load the drivers from the official lg site. when here you enter the code that is on the box the phone came in or under the battery.
Chose the your county and laguage from the drop down box at the top right of the dialogue box. Then from the middle you can choose the drivers. For some reason I had to find the files and click on them to install the driver.
Ok once you decompress kdz updater there are three seperate files to work with. 1. windows enabler. 2. msxml.msi 3.KDZ_FW_UPD.exe
You will also need to download the right file to restore with,You can find it with google.
Please check here the The_ERROR thread wich explains it very well:
[ROMS] Original LG Firmware list.
Install msxml now.
Now you have to boot the phone into rescue mode. On Lg Optimus One turn phone off even if it means taking out the battery.
Press power - volume up - back (this button is next to the home button).
Connect to usb now.Computer found new hardware and installed four drivers.
Then open device manager. Left click my computer - properties - device manager. You need to disable the lg modem driver. Left click on it and disable.
Now launch kdz updater. There will be a drop box on left set to 3gspt or similiar. on the right drop box set to diag. The long box just above the info box with a file at the side lets you browse to find restore file. e.g. V10a.00.kdz.
Double click the button below and let it do it's thing. Took 15min. My phone shut down and came up with an error at the last minute. Anyway I rebooted and all was good.
Everything was the way I left it. Just had to re-root.
My only real problem was getting the kdz installer to see the phone.
After installing the drivers restart pc. If it finishes quickly and just before saying finished it says phone not found try removing all phone related drivers including nokia pc suite and the lg suite and remove and reinstall the drivers.
Hope this is of some help to you.
