    • I have just updated the article with the download link of all the files required during the process of update.

  3. Hi Neal,

  5. Neal,
    im curently on HTC ROM will it affect when i update tho this? Can I install HTC again? Thanks I will be waiting for you reply.

    • Thanks for your interest but we would provide you with an article within a day or two or HTC phones for CyanogenMod 7.1.
      Check back soon.

      • I think he meant he has a galaxy s with an HTC ROM installed on it..
        So to answer your question, I’m not an expert, but i think that this rom will overrun your current rom.. meaning, that the old htc rom will be deleted, unless you backup with ROM manager which u can download from the market for free, and the new cyanogen rom will be installed.

        not so sure. but hopefully this is right, confirm with yogesh though .

  6. Neal,

    If we have already rooted 2.3.5 usging the steps you have provided ealier, can we not just download CynogenMod file and install it from SD card ? do we still have to go through all the steps from installing the Clockwork and then install Cynogen.

    or Can we not just install Cynogen without Clockwork ?

  7. Hi Neal, would you happen to know the *call quality* in India, with this version of Cynogenmod ?

    A couple of months ago I’d tried ver 7.0, but callers could barely hear me and there were tons of dropped calls as well. I tried switching multiple modems but none worked – and so I moved back to stock XXJVR (2.3.4)

  8. Neal,
    Im currently on HTC Sense ROM, if I update with this ROM will the HTC sense be removed? and can I install it back? I will be waiting for you reply.

  9. Hey Neal,

    I had a problem while doing this update, I had done everything proper in the ROM manager, but when it gets to the installation of the mod in the ROM manager, it takes me to the clockwork mod n then there it says installation aborted. What am I to do? should i continue with the update? Help!

    • also the uploaded file to download is in .rar format, i thnk the galaxy takes .zip files. so another reason it didnt work on my phone.. maybe?

      • yeah, had some issues with rar file. Reuploaded it again, try it out. Thanks for your patience.

        • The installation process is still not going through.. i downloaded the newly uploaded file, set it in my sd card folder, put my phone on recovery mode, wiped data and cache, then tried to install zip from sd card n the downloaded file was there so then i clicked it to perform the task, but in a few seconds it says installation aborted.. what to do??
