The most coveted of all the custom ROMS, the CM7 ROM, has been available for LG Optimus GT540 for sometime. Only couple of weeks before, a new version 2.3.4 was released and I just tried it out and was completely amazed by the ROM, just like everybody who has ever tried it is. Following is the tutorial for all LG GT540. The whole time I’ve used this ROM I have not had any problems, everything works perfect and fast. LG Android Phones

Hello, and thanks for being so clear in your tutorial. I just have a problem with the files to download, because of the new policy of FileServe (only the uploader can have access to his/her files). I have tried to locate the file containing KDZ Updater and RomFastboot, but to no avail. Could it be possible for you to upload it to another site ? If necessary, I could give you an ftp address. Many thanks, superem
Same problem as per @superem.
I am not able to download http://www.fileserve.com/file/CVF2r9v file. Can you give me another url for download? Thanks in advance.
