Hi.
There is a script for my (future) tablet out there, it is supposed to make the tablet work smoother.
Unfortunately there are reports that the tablet gets very slow after a longer time without reboot.
Can anybody look over the script and tell me what the problem could be?
Tablet is a Hannspree Hannspad, rather similar to Advent Vega.
Thanks in Advance

Wifi tweaks
This wifi tweaks is enabling N standard and 5ghz band
Credits Goes to Graveir 1. go to /system/etc/firmware
2. find this file name
Code:
fm_rx_init_1273.2.bts
fm_tx_init_1273.2.bts
fmc_init_1273.2.bts
3.Are they there? good you will have 5ghz band. Are they not there? you wont get 5ghz band
4.Go to /system/etc/ and find tiwlan.ini Note: In CM7 based ROMs the path may be /system/etc/wifi
5.Look for the following lines:
Code:
HT_Enable=0 #0=disable 802.11n support / 1=Enable
BurstModeEnable = 0 # 0 - Disabled 1 - Enabled
WiFiAdhoc = 0
and change them into:
Code:
HT_Enable=1 #0=disable 802.11n support / 1=Enable
BurstModeEnable = 1 # 0 - Disabled 1 - Enabled
WiFiAdhoc = 1
6. This stage is for people who have file from step 2
Look for the line
Code:
Single_Dual_Band_Solution = 0
And change them into
Code:
Single_Dual_Band_Solution = 1
7. Save, reboot

.And thanks for other. will try this evening
Thanks. I'm gonna try some tweaks..

working in Gingerdx v17+LinuxDx v004.. thanks buudy!
u have to copy the file to the init.d folder, then set peimissions of it with root explorer
Erm... i think 40MB for dalvik vm heap is better. And SD Card read ahead cache BEST size is 2048 KB. Tried for about a 100 times, 2048 KB is BEST .
/sys/devices/virtual/bdi/179:0/read_ahead_kb is the file
Oh and my /etc folder is attached, take all the files you want from it.
By the way don't take the wifi files . They don't work I think...
Don't replace your entire folder with my folder, just take the stuff you need .
Of course, mine is not perfect .
And settings should be:
Code:
echo "20" > /proc/sys/vm/vfs_cache_pressure
echo "95" > /proc/sys/vm/dirty_ratio
echo "60" > /proc/sys/vm/dirty_background_ratio
Please make a version with tweaks to 2.1

NOOOOOOO xD
With that Cache size the music has hiccups.
Probably if you have an higher class sdcard, that cache size will be good, but with Class2 and Class4 there is hiccups when you're listening to music
128KB for Slow MemoryCards
Any of this tweaks allow us to connect to eduroam networks?
XtremePeople, u should warn people, because enabling WiFi .n makes wifi work very unstable -___-

i download the v3 tweak. after i extract,wat should i do? copy all files in the folder to init.d folder?
Hi everyone,
I have just one question to ask:
In every init.d file that I've found, it's been divided-- some lines are with semicolons, others are one. Most have both, which confuses me greatly...
AND they're right next to each other; for example, in the Pimp My Rom tweaks,
The S10vm tweak has all but one semicolon-ed:
Code:
#!/system/bin/sh
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
In the S36iosched file, almost none are semicoloned:
Code:
#!/system/bin/sh
mount -o remount,rw /sys /sys;
mount -o remount,rw /system /system;
echo 2 > /sys/block/mmcblk0/queue/iosched/fifo_batch
echo 2230 > /sys/block/mmcblk0/queue/iosched/write_expire
echo 300 > /sys/block/mmcblk0/queue/iosched/read_expire
echo 2230 > /sys/block/mmcblk0/queue/iosched/async_write_expire
echo 300 > /sys/block/mmcblk0/queue/iosched/async_read_expire
echo 2 > /sys/block/mmcblk0/queue/iosched/writes_starved
echo 2230 > /sys/block/mmcblk0/queue/iosched/sync_write_expire
echo 300 > /sys/block/mmcblk0/queue/iosched/sync_read_expire
mount -o remount,ro /system /system
mount -o remount,ro /sys /sys
It's driving me nuts (I'm compiling my own init.d file) and I'm not sure whether to include the semicolon or not >__>
Thanks for your definitive response; it is very much appreciated!
The semicolon is a command separator. If command are separated by a new line, you don't need a semicolon. Inserting one won't make any difference.

Okay, thanks for your response! It's much clearer now.
For those of you who like to do additional tweaks to your phone, what init.d and build.prop tweaks do you use? I've noticed some of them try to override crpalmer and Zarboz's kernel settings so I removed them. Also, I've read that some of these tweaks don't help at all.
So what tweaks do you recommend, if any, that play well with the DNA and with custom kernels?
Currently I have speedscript in my init.d folder but I noticed no benefit or detriment so I may just remove it. I also reduced the WiFi scan interval in the build.prop. I would like to add more tweaks since I can't leave well enough alone.
I'm looking for speed and battery improvements which can he a fine balancing act. I also want to increase the scroll speed as wel as change the autobrightness settings so it's more biased to lower brightness. I'm not sure if those could be achieved with init.d or build.prop tweaks.
#Render graphics with GPU&CPU
debug.composition.type=cpu
debug.composition.type=gpu
#For Faster Startups Disable Boot Animation
debug.sb.nobootanimation=1<<< faster
[QOUTE]Many build.prop tweaks set this value to 300, but it seems this is a bad idea. As Google points out, Android maxes out at 60fps. The default value is already allow for a possible max_events_per_sec of 90. Even if you allow for 300 max_events_per_sec, you’ll only ever see 60 of these events in any given second. Therefore, any value much higher than 90 is unlikely to have any noticeable impact on your experience in general. Additionally, setting this value too high can starve other UI events that need to get processed, viz. touch inputs. You’re not likely to feel like your device is running very smoothly when it is busy processing thousands of scroll events instead of responding immediately to you clicking to try and open a link or an app. There may be some specific scenarios where increasing this value does appear to improve system feedback, but changing this value for all UI events across the board will likely cause more problems than it will solve.[/QOUTE]

busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /cache
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;

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 "4000,5000,6000,10000,15000,20000" > /sys/module/lowmemorykiller/parameters/minfree
I see other members using 1000,2000,... or lower for minfree.
If I use my value for my neo, firefox closes when I load some image heavy page.
If I use lower value for my neo, it reboots in the same situation.
It is pretty strange. Please give some advises.
p.s. my vm.min_free_kbytes is 4096, related?

Of course, plese I added smartassv2 setting to this scripts too. But they will not work if you didn't choose smartassv2 as Your Governor. Delete ".txt" and push one of them to init.d folder.
