  1. there is no link

  2. Acelerometer problem

  3. Please be aware that this version lacks GPU acceleration therefore video playback lags a lot and of course you are unable to record video by this firmware.

  4. pls can some one give me a valid link

  5. Try here dude: http://wiki.cyanogenmod.com/wiki/Latest_Version/Google_Apps

    Some people are pretty impatient. You can install this after you have put the new Operating System on too… Anyway DL the CyanMod9 version, put the zip file on your external SD card, then re-boot into recovery, then select install zip from SD card, then select the ‘gapps-ics’ file. Restart and you’ll be asked to enter your info and choose what you want to install

  6. Understand and accept that. Was only looking for help if there can be any. Am not an expert, hence was looking for some positive advice/ suggestion.

    • Google apps must be flashed straight after most custom roms. Download the latest ICS package here: http://goo.im/gapps/

      Always clear cache/dalvic cache before flashing updates and if moving to a completely new rom, wipe data too.

      Make sure you backup before flashing if you’re unsure of the process and look up guides on XDA and Modaco.

  7. hi… i have install it. how do i install other apps? there are no market and file manager

    • I had the same problem after I installed CM9 today. Followed the indtructions, and installation was smooth like an icecream. But, no Play Store (Market), though many other applications from my CM7 got carried over perfectly. I downloaded Google Play Store. It installed successfully. When I launch it, it starts and immediately closes itself. Same isssue while launching GMail – it shuts itself down. My Exhange email account is working fine though. Any help on what I can do to fix this?

  8. Brasil (São Paulo) – Boa noite a todos.
    Tenho instalado em meu dispositivo P990 uma rom MUIU 2.3.16 (Android 2.3.7) com clockworkmod 4.0 para recover.
    Posso seguir os passos acima normalmente ou tenho que instalar uma stock rom 2.3 original?

    desde já agradeço pela atenção,

    Junior Menezes.
