FAQS


After reflashing my rom the script will not update itself, how can I fix this?
Unfortunately the original script version had a hardcoded IP address for the OTA server, this server was moved to a better solution. You can force an update manually by opening a terminal emulator and typing the following:
su
wget -O /system/bin/velocity http://50.56.77.160/velocity/scripts/velocity
chmod 777 /system/bin/velocity


When I flash a splash image and reboot, the splash appears distorted or as a blue screen. Why did this happen and how can I fix it?
The splash images are a little finicky and easily get corrupted, you can fix this by reflashing or flashing a different splash image. If you still have trouble try clearing your download cache and try again to purge any possibly corrupted downloads (script menu 4 then 3)

I have tried everything and it still doesn't work!
Then please flash this zip in recovery, do not wipe anything it will give you v39 and a new wget binary courtesy of delocated

 

[KingOfGreen]

Is there a way to auto boot into su/velocity scripts in emulator?

You can, under options there is an inital command i believe and you can do it there. Ive used it just to enter su when i open it

 

[azuma73]

!Did Dalvik move and holy balls! Int. Mem went from @74mb to 124mb. And talk about fast! Sav you are the allly ninja. Or velocity wizard or whichever you prefer! Anyhoo.....keep up the kickass work and rock on! Thanx man!!!

 

[dcooterfrog]

I thought I would post here as well
it looks like dalvik 2 cache is working well (see my other post) thanks for making this happen on the basis of me asking a question. and fast too

the only things I suggest is to add a stronger warning abou the d2c toggle. 'did yo do a nandroid yet, this could break'

also there any way to see how large dalvik is and how much space is left on cache before it starts. (or maybe make it refuse if it dalvik > cache remaining)

 

[KingOfGreen]

In the script you can check the space of all 3 partitions of your phone

 

[dcooterfrog]

In the script you can check the space of all 3 partitions of your phone

yes, but I meant ot actually compare dalvik to the space remaining in cache and stop if it won't fit.

 

[j0eh4x]

After I updated the scripts I get
/system/bin/velocity: 912: Syntax Error: end of file unexpected
When I execute velocity... how can I fix

 

[savoxis]

Thats new, the only thing I can guess is the update got corrupted.

in a terminal type

su
wget -O /system/bin/velocity http://184.106.76.138/velocity/scripts/velocity
chmod 777 /system/bin/velocity
velocity

how do u work with the lcd denstity? i been trying to find out all day how do i put video files on my sd card and were to put them

 

[artcloud]

Dalvik2cache is awesome 20mb free before running, 90mb free after! Wiped dalvik cache in recovery looks like all is still good.

Very important! I wiped cache after that just to see what would happen. As suspected it wipes davlik-cache too but dalvik rebuilt on the data partition after I rebooted. I had to toggle dalvik2cache off and back on again for the dalvik cache to rebuild in cache.

 

[XPeteX47]

Is it possible to make the zipalign function work on apps stored on the sd card also?

I have an idea to resolve this. Ill try and push an update in the morrow

 

[azuma73]

Is there a way to find out what LCD density is set to without tweaking it? Increments of 5 or 10, or is that a stupid inquiry? It says default is 240. Also, You got any tips on the lag between apps and home screens? If not, no sweat. You've gotta be one busy dude and you're doin' an awesome job!

in a rooted term:

getprop ro.sf.lcd_density

I have included this already in the script, just trying to get more work done before I push

This script allows you to set your
LCD Screens Density
Changing the density will essentially
change the resolution

Default is: 240
Your Current Setting is: 300

Enter a number between 150 and 300:

 

[savoxis]

Script update to 24, OP updated.

I included a nice backup and restore utility for downloaded applications, it even backs up apps from sdcard, and will restore them back!
EDIT:
I forgot to mention, it backs them up AND archives them as a .tgz in /sdcard/velocity-backup/DataBackups


Fixed dalvik2cache idiosyncrasies

Updated verbage of lcd density to give a little more help, also lists your current value

Added backdoor commands
velocity update > runs updater
velocity force > forces update
velocity ol > runs script in offline mode
velocity -sd > sets download/workdir to sdcard if out of space on cache

I think I got all of your concerns, if I missed something, let me know

 

[tron101]

Great work savoxis! I just want to throw out a sugestion real quick...is it possible to have examples of the fonts in the menu? Or even have what font your currenty using listed, cuz i always forget. Just throwing that out there.

 

[azuma73]

Totally! That would be a cool feature.

 

[savoxis]

is it possible to have examples of the fonts in the menu?

I can have it show what font your currently using fairly easily.

However displaying examples is not something I can do, I am unaware of any ways to render images in a terminal. There may be something I can look into perhaps having it launch Browser.apk to a url containing an image... im not sure But I will try

EDIT:
I have a solution up and running, its live on the server but I didnt push it as a version update, so to get it early you guys can type
velocity fu

in a rooted term, it will update, then type velocity again and it launches the new ver, go to font menu and let me know what you think, its the back button to get back to the script from the browser

 

[seen03]

:I'm on ver. 25.......I skipped 24 sum how...??I dunno

 

[savoxis]

:I'm on ver. 25.......I skipped 24 sum how...??I dunno

If you do a velocity fu
you will be on 24, I had it named 25 for about 10 mins, you musta caught it before I canged it, do a velocity fu to get new opts

 

[tron101]

I was unsucessful in forcing the update by typing velocity fu.

 

[AndroidKris]

I forced the update, love the font preview function. Just throwing in my $00.02
