    Hier mal eine liste mit tweaks und scripts. hab selbst die meisten ausprobiert und hab bisher keine probleme.

    [TWEAKS][SCRIPTS] Collection of 'em all - build.prop; init.d; etc. On my ROMs adventure I've been collecting some tweaks and scripts and seems to me it's now time to share it. While some values in terms of optimization might fluctuate from device to device, I've found these pretty consistent throughout many.

    Build.prop
    (edit your /system/build.prop with a file manager with root access)

    Careful for already existing settings. In this case, just change the values.

    1. Force launcher into memory

    Code:
    ro.HOME_APP_ADJ=1
    2. Raise JPG quality to 100%

    Code:
    ro.media.enc.jpeg.quality=100
    3. VM Heapsize; higher the RAM, higher the hp can be

    Code:
    dalvik.vm.heapsize=48m
    4. Render UI with GPU

    Code:
    debug.sf.hw=1
    5. Decrease dialing out delay

    7. Save battery

    Code:
    wifi.supplicant_scan_interval=180 pm.sleep_mode=1 ro.ril.disable.power.collapse=0
    8. Disable debugging notify icon on statusbar

    Code:
    persist.adb.notify=0
    9. Increase overall touch responsiveness

    Code:
    debug.performance.tuning=1 video.accelerate.hw=1
    10. Raise photo and video recording quality

    Code:
    ro.media.dec.jpeg.memcap=8000000 ro.media.enc.hprof.vid.bps=8000000
    11. Signal (3G) tweaks

    Code:
    ro.ril.hsxpa=2 ro.ril.gprsclass=10 ro.ril.hep=1 ro.ril.enable.dtm=1 ro.ril.hsdpa.category=10 ro.ril.enable.a53=1 ro.ril.enable.3g.prefix=1 ro.ril.htcmaskw1.bitmask=4294967295 ro.ril.htcmaskw1=14449 ro.ril.hsupa.category=5
    12. Net speed tweaks

    Code:
    net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960 net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960 net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960 net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960 net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960
    13. Disable blackscreen issue after a call

    Code:
    ro.lge.proximity.delay=25 mot.proximity.delay=25
    14. Fix some application issues

    Code:
    ro.kernel.android.checkjni=0
    15. Phone will not wake up from hitting the volume rocker

    Code:
    ro.config.hwfeature_wakeupkey=0
    16. Force button lights on when screen is on

    Code:

    19. Specifics to some LG devices

    Code:
    persist.service.pcsync.enable=0 persist.service.lgospd.enable=0 user.feature.flex=true user.feature.lgdrm=false user.feature.lgresource=false user.feature.lgpoweroff=false user.feature.ls_event=false user.feature.ls_normal=false user.feature.sui=false

    Init.d
    (needs ROM with init.d access and busybox, open empty file, insert header #!/system/bin/sh and put these there, save in /system/etc/init.d and name it something like 77tweaks)

    1. strict minfree handler tweak

    Code:
    echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
    2. internet speed tweaks

    Code:
    echo "0" > /proc/sys/net/ipv4/tcp_timestamps; echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse; echo "1" > /proc/sys/net/ipv4/tcp_sack; echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle; echo "1" > /proc/sys/net/ipv4/tcp_window_scaling; echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes; echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl; echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout; echo "404480" > /proc/sys/net/core/wmem_max; echo "404480" > /proc/sys/net/core/rmem_max; echo "256960" > /proc/sys/net/core/rmem_default; echo "256960" > /proc/sys/net/core/wmem_default; echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem; echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
    3. vm management tweaks

    Code:
    echo "4096" > /proc/sys/vm/min_free_kbytes echo "0" > /proc/sys/vm/oom_kill_allocating_task; echo "0" > /proc/sys/vm/panic_on_oom; echo "0" > /proc/sys/vm/laptop_mode; echo "0" > /proc/sys/vm/swappiness echo "50" > /proc/sys/vm/vfs_cache_pressure echo "90" > /proc/sys/vm/dirty_ratio echo "70" > /proc/sys/vm/dirty_background_ratio
    4. misc kernel tweaks

    Code:
    echo "8" > /proc/sys/vm/page-cluster; echo "64000" > /proc/sys/kernel/msgmni; echo "64000" > /proc/sys/kernel/msgmax; echo "10" > /proc/sys/fs/lease-break-time; echo "500,512000,64,2048" > /proc/sys/kernel/sem;
    5. battery tweaks

    Code:
    echo "500" > /proc/sys/vm/dirty_expire_centisecs echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
    6. EXT4 tweaks (greatly increase I/O)
    (needs /system, /cache, /data partitions formatted to EXT4)

    a) removes journalism

    Code:
    tune2fs -o journal_data_writeback /block/path/to/system tune2fs -O ^has_journal /block/path/to/system tune2fs -o journal_data_writeback /block/path/to/cache tune2fs -O ^has_journal /block/path/to/cache tune2fs -o journal_data_writeback /block/path/to/data tune2fs -O ^has_journal /block/path/to/data
    b) perfect mount options

    Code:
    busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /system busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
    7. Flags blocks as non-rotational and increases cache size

    Code:
    LOOP=`ls -d /sys/block/loop*`; RAM=`ls -d /sys/block/ram*`; MMC=`ls -d /sys/block/mmc*`; for j in $LOOP $RAM do echo "0" > $j/queue/rotational; echo "2048" > $j/queue/read_ahead_kb; done
    8. microSD card speed tweak

    Code:
    echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
    9. Defrags database files

    Code:
    for i in \ `find /data -iname "*.db"` do \ sqlite3 $i 'VACUUM;'; done
    9. Remove logger

    Code:
    rm /dev/log/main
    10. Ondemand governor tweaks

    Code:
    SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000) echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
    11. Auto change governor and I/O Scheduler

    a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these

    Code:
    echo "vr" > /sys/block/mmcblk0/queue/scheduler or echo "sio" > /sys/block/mmcblk0/queue/scheduler
    b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these

    Code:
    echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    12. Auto-zipalign on boot
    (needs zipalign bin)

    Code:
    [Q]zipalign on boot code - xda-developers
    13. Loopy Smoothness tweak

    Code:
    http://forum.xda-developers.com/show....php?t=1137554 http://forum.xda-developers.com/show....php?t=1205744
    14. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space

    Code:
    CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2) if [ $CACHESIZE -gt 80000 ] then echo "Large cache detected, moving dalvik-cache to /cache" if [ ! -d /cache/dalvik-cache ] then busybox rm -rf /cache/dalvik-cache /data/dalvik-cache mkdir /cache/dalvik-cache /data/dalvik-cache fi busybox chown 1000:1000 /cache/dalvik-cache busybox chmod 0771 /cache/dalvik-cache # bind mount dalvik-cache so we can still boot without the sdcard busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache busybox chown 1000:1000 /data/dalvik-cache busybox chmod 0771 /data/dalvik-cache else echo "Small cache detected, dalvik-cache will remain on /data" fi
    15. Disable normalize sleeper

    Code:
    mount -t debugfs none /sys/kernel/debug echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
    16. OOM groupings and priorities tweaks - SuperCharger

    Code:
    [Script][Update 9 Beta 6!] V6 SuperCharger! The ONLY Android MEMORY FIXER! 3G & KAK! - xda-developers

    GPS.conf
    (create or edit your /system/etc/gps.conf with a file manager with root access)

    For improving GPS lock time and signal.

    a) European NTP server (replace for america or asia in your case)

    Code:
    NTP_SERVER=europe.pool.ntp.org XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
    b) SE supl for A-GPS (better than Nokia's or Google's)

    Code:
    SUPL_HOST=supl.sonyericsson.com SUPL_PORT=7275

    Other tweaks or guidelines

    1. Patch your hosts file for blocking Ads
    (please think before doing this; many developers are supported through this way)

    Code:
    You can use AdFree application for this or changing manually your hosts file. Here are some databases: http://www.mvps.org/winhelp2002/hosts.txt Ad server hostnames for blocking ads (format: hosts -- in hosts file format)
    2. Use CyanogenMOD's APN list file - it's one of the most complete.

    Code:
    It's located in /system/etc/apns-conf.xml
    3. Use UOT kitchen for basic theming on your device.

    Code:
    UOT Kitchen
    4. Use Google's dns servers

    Code:
    Create an empty file, name it resolv.conf and put there these 2 lines: nameserver 8.8.8.8 nameserver 8.8.4.4 Save to /system/etc/.
    5. Update Superuser and su binary to latest version (3.0 beta)

    Code:
    goo-inside.me - superuser downloads
    6. Disable sync feature in sqlite
    (author: ownhere - needs a source for your device so you can compile the /system/lib/libsqlite.so)

    Code:
    Patch file here: [dev][sqlite3] 21/Jan, how to disable sync in sqlite3 without pragma - xda-developers
    7. Do not use task killers.


    Alright, I think this is it for now.
    If you have any other tweaks or better values, you can PM me and I'll include them.

    11. Signal (3G) tweaks

    Code:
    ro.ril.hsxpa=2 ro.ril.gprsclass=10 ro.ril.hep=1 ro.ril.enable.dtm=1 ro.ril.hsdpa.category=10 ro.ril.enable.a53=1 ro.ril.enable.3g.prefix=1 ro.ril.htcmaskw1.bitmask=4294967295 ro.ril.htcmaskw1=14449 ro.ril.hsupa.category=5
    12. Net speed tweaks


    2. Schaltet der code debug.sf.nobootanimation=1 nur die Animation aus oder auch rein zufällig den Startsound? (Benutze zwar Silentboot, aber das könnte man sich ja dann ersparen.)
