Wrong wording perhaps. I meant more like, why even bother asking? Other recoveries such as TWRP often have compatibility issues, but CWM is like THE standard custom recovery as far as the Atrix is concerned. Of couse it can be used to flash pretty much any ROM packaged as a flashable ZIP.

Quick question.

When recording video everything is fine for about 20-30 secs and then it stops recording the image but i can still hear the audio...
This almost always happens when i record a longer (above 30 secs) video.

Has anyone else experienced this? :(

Still a great ROM :)

    - Fast - Slick - Clean - Smooth - Lite - Efficient - Small -
    This ROM is based on the Latest Nightly (currently 20120812)
    But has many added optimizations.





    - Massive 54% cut in size
    CM7 + gapps = ~150mb uncompressed,
    Neutrino ROM = ~80mb uncompressed.

    Results in a much snappier, unsluggish and fast experience.

    - Beautiful theme
    Minimalistic styled theme, Slim Roboto fonts and bits of ICS, such as ICS animations, icons and ICS-styled settings..

    - MIUI camera
    MUCH higher quality camera with touch to focus.

    - PNG Optimized/Zipaligned
    Uses DarkyROM's fast zipalignment to increase RAM efficiency. All system .apk's are also PNG optimised to make .apks smaller.

    - Wi-Fi/3G tweaks
    Tweaked net buffer size and added network init.d scripts for faster 3g/Wi-Fi.

    - Increased Dalvik cache to 160m
    Increased efficiency with demanding apps and increases smoothness.

    - Reduced background processes
    Removed CMstats as well as unnecessary Google bloatware to increase snappiness and battery life.

    - Android 4.0 ICS Fuju Tweaks
    Results in ICS smoothness and responsiveness.

    - Touch response Tweaks
    Better sensitivity, greater precision when typing and overall smoother scrolling and performance.

    - SD Card tweaks
    Increases read/write speeds on microSD card.

    - Battery Tweaks
    Adjusted and added build.prop and init.d lines to increase battery efficiency.

    - Enabled Stagefreight
    Faster video streaming.

    - V6 Supercharged
    Tweak's OOM's, minfrees to improve RAM efficiency and make everything smoother.

    - FULL GPU rendering
    Uses ONLY GPU to FULLY render the UI, making everything much more smooth and fluid.

    - Ext4 w/o journaling
    Removes the journal from Ext4 which heavily increases I/O speeds and makes everything faster.

    - Kernel and Networking tweaks
    Improves kernel efficiency as well as faster Wi-Fi and data. Also contributes to much better overall efficiency and smoothness

    - qHD Keyboard
    Nice and large WP7 themed keyboard, made to fit qHD resolution.

    - I/O tweaks
    Improves database efficiency, and makes everything fell fast and smooth.


    Please read before downloading

    This is an enormously STRIPPED DOWN ROM. Many features YOU need may NOT be available in the base package. If there is any loss of functionality, you'll need to flash an ADDON by clicking the link below.

    Before you download, ensure your contacts are saved onto your SD card or memory card. Contact/calender sync is not included natively, you must flash the 'Sync addon.'

    This is a CM7 BASED ROM. So anything that doesn't work on CM7 like Webtop will NOT work on this ROM also. Please do not request non-CM7 features.
    Install Instructions:
    **Firstly make sure you have the latest RomRacer's recovery!!**
    Then choose to wipe using any one of the following two wiping methods:
    For clean wipe:
    Moto-fastboot -w, erase system/boot/preinstall, then install from INTERNAL .ZIP!

    For easy wipe:
    Go into recovery, and install from INTERNAL .ZIP!
    Wiping data may not be necessary with every update, but it's best to flash clean. However, if you regularly flash the updates, you'll most likely need to wipe data at some stage anyway.
    Make sure you flash the 'Lite gapps' in to get the barebone google apps.

    Then, after booting, click on script manager, navigate to /system/etc and run NitroCharger.sh as ROOT and at BOOT!
    It is also HIGHLY recommended to download the GPS Mod found in #2.
    Then you're done.

    Q: Are you going to be working on CM9?
    Yep, I'm working on it right now :)

    Q: My phone doesn't boot with this ROM - it get's stuck on the dual-core screen :(

    Q: Why is performance settings in CMparts removed?
    A lot of options in performance settings will conflict with the tweaks in this ROM. All the options in performance settings have been included in the ROM anyway, but have been optimised for the best settings. So don't worry about it. If you REALLY want to head over to performance settings, then long press on homescreen and select shortcut. Add CMparts>Performance Settings and you will gain access. But seriously, there's really no point.

    Q: My phone shows that I have very low free RAM!
    Here's a fat explanation on how the RAM works in Android.

    Q: My phone can't scan files on my SDcard?
    CM7 mounts the SDcard and internal memory opposite to Motorola. To switch back to 'stock style,' navigate to /settings/CMsettings/application > Check 'use internal storage' and reboot.

    Q: Does this ROM support landscape mirroring?

    Q: How do you get those cool 'ICS style' rings like in the screenshots?
    Go to Settings/CMsettings/Lockscreen/Style options/Ring-Lock style and change to 'holo.'

    Q: What does the BOOST script do?
    It will 'defrag' databases, so make them smaller (faster to read, so apps will open faster) as well as freeing the caches. Do NOT run this script at boot!!!!! It is to be used if your phone starts to feel a big sluggish or laggy, then just run the script with SU and that's it.
    Video Review!

    Thanks to J-Roc for reviewing! :cool:
