Updated: expand initramfs ramdisc from zImage kernel, supports gzip, lzma, bzip2 (?)

If you are interested in building your own kernels (from the Samsung-released open-source code, or any other source), you may need to extract initramfs ramdiscs from existing kernels.
There is a well-known script to achieve that goal, but it only supports uncompressed and gzip'ed kernels, and it doesn't unpack the CPIO archive for further inspection of the actual initramfs "source code" (the output trace is also not easy to debug when working with "weird" zImages). The original script is explained in the XDA wiki: http://forum.xda-developers.com/wiki/index.php?title=Extract_initramfs_from_zImage.
For my personal convenience, I tweaked the original bash script so I thought I'd share it with the XDA devs. I added support for lzma-compressed initramfs ramdiscs (thanks to koxudaxi for reminding me of the lzma "magic string"), please let me know if you know the "magic string" for bzip2 archives (EDIT: "0x314159265359" 6 bytes "start of block", 4 bytes header at the beginning...experimental untested support is now available in the script below).
Note that the latest Samfirmware ROMs include encrypted boot.bin and Sbl.bin bootloaders, but I'm not sure how the zImage kernels are encoded...so this script may not work.
Also note that zImage files patched with z4mod require further decoding work, see the XDA wiki page mentioned above for instructions.

[VRTHEME][JB 4.1.2 LSx] Change updater-script & installtheme.sh [FOR 2dn ROM Only]

[VRTHEME][JB 4.1.2 LSx] Change updater-script & installtheme.sh [FOR 2dn ROM Only]
VRTHEME FILES for 2ND ROM ONLY
Original user of S2 I9100 JB 4.1.2 ROM on 2ND ROM, i also want to use Themes and Mods for JB 4.1.2 LSx ROM i found on XDA I9100 threads.
Most are based on http://forum.xda-developers.com/showthread.php?t=1207017 .
To flash them on 2nd ROM, again we have to re-script updater-script and installtheme.sh scripts.
REMEMBER, when we use a 4.1.2 JB ROM as second rom, most of the files which are in /preload/symlink/system/app/* are finaly placed in /data/sec_data/*
so we have to use this PATH in updater-script and installtheme.sh .
In most of the themed ZIP original file we find on XDA, some apks system are in /system/app or /preload/symlink/system/app , be carrefull of this,
in VR-Themed ZIP file we want to moddify for 2nd ROM , sometimes, we have to move /preload/symlink/system/app/xxxxxxxx.apk in /vrtheme/system/app/xxxxxxxx.apk before using it.
so, about using the original VR-Theme or VR-Mod zipped files found on XDA, my different purposes for theming are :
if system files are in /preload/symlink/system/app , they will be themed in /data/sec_data
if system files are in /preload/symlink/system/app , they will be themed in /preload/symlink/system/app (if you use on 1rst ROM)
if system files are in /system/app , they will be themed if they are in /system/app or /data/sec_data/ or /preload/symlink/system/app too
At my sens, the only way to have an error is to put some xxxxxxx.apk folders in /vrtheme/system/app/
which are in fact LNs files in /system/app/ on TEL, (in 2nd ROM, partition /system/ = /preload/ !)
Another way to undertand it, it's that there is no way to destroy symlinked files in /system/app/* (on tel) because no files from /vrtheme/system/app are unknow from you, (the only files we find in are managed by you, by deplacing some themed xxxxxxxx.apk folder from /preload/symplink/system/app, because ROM on TELhave on 2nd ROM too. On another terms too, we can manage apks systems files in /data/sec_data/* instead of /system/app/* (preload/app/*) so only xxxxxxxx.apk directories which are volontary in /vrtheme/system/app/* would be themed in /system/app/ on your 2nd ROM.
for example, flashbarservice.apk can be found sometimes in/system/app and sometimes in /data/sec_data/
Anyway you have to ALWAYS verify the xxxxxxxx.apk directories placement in the Original ZIP Theme or Mod file before flashing it
i think my updater-script and installtheme.sh are also fonctional for apks in /data/app/
Remember that generaly, a file xxxxxxxx.apk is patched on phone only if it exist a ZIP folder named xxxxxxxx.apk in /vrtheme/system/app/, /vrtheme/system/framework/, /vrtheme/preload/symlink/system/app/, /vrtheme/data/app or now /vrtheme/data/sec_data/ , and in the TEL, in /system/app/ , /preload/symlink/system/app/ , /system/framework/ , /data/app/ and /data/sec_data/
Give a try on my sample MIX here : https://mega.co.nz/#F!bhww0QYT!L2cnHS84iZJC7aCvdTmFjg
updater-script and installtheme.sh in attachments are to replace those in your original theme or mod files you find , at the same place which there are , to avoid the desired theme or mod in your 2nd ROM.
(delete ".pdf" at the of name file to use it)
i try to be explicit as i can with my (very limited) bad school english
Thanks.
New Update V2 version of this particular updater-script, only for file which are in \vrtheme\data\sec_data\, (and usual \vrtheme\system\app\ and \vrtheme\system\framework\ for sure)
Version before managed \vrtheme\preload\symlink\system\app\ so it was a waste of space in sdcard, i reduce that because THIS IS only for second rom usage, so update if you use.
lines from new updater-script :
package_extract_dir("vrtheme/data/app", "/sdcard/vrtheme/data/app");
package_extract_dir("vrtheme/data/sec_data", "/sdcard/vrtheme/data/sec_data");
package_extract_dir("vrtheme/system/app", "/sdcard/vrtheme/system/app");
package_extract_dir("vrtheme/system/framework", "/sdcard/vrtheme/system/framework");
NO PRELOD here.
Thanks

toolpack and how to for 2nd ROM ONLY
hope it's the best how too i post for adapt mod and vrtheme for 2nd ROM use !

Trinity ROM and kernel already has many tweaks applied in it.. You don't need to try any.. If u have a Stock ROM without any mods, but with some custom kernel, then try this..

Trinity Rom has tweaks but they are not enabled by default as in init.d does not run at boot... It never did in his previous roms either, and I don't think he is to bothered to fix it!

Yes. Its your choice in Aroma to select which kind of tweaks you need.. Anyway try this.. Do have a backup.. Lets not spam this thread.. There's another thread to discuss about Trinity ROM..

Hi, Just like.I.said, Ive added Init.d enabler on. 3.6 via.Settings.apk
Even you install this tweak it will never work, unless you enabled some required perm. For the init.d files

You are referring on your ROM or you genaralise?
If you are using stock ROM, rooted and deodexed I don't see why it shouldn't work (at least some part of it)

I still haven't tried but guys, when you try it, test firmly.
Every device will fly after restart - when you restart it - your RAM gets cleared and device will work softer and faster.
Try to see what's happening after one or two hours - don't fall on placebo effect afrer restart.
And please, don't get me wrong, I'm not saying it doesn't work, I haven't tried it yet.
I'm just saying how to test

Tested. Well done. I report two bugs, some apps does not start automatically after a reboot,like Antitirus,etc. and photos won't open from Album Widget, only from the album itself.Anyway, good job, waiting for a stable version,until then, I'm back to my backup.

sure

99swap doesnt run from init.d

I am on MIUI ICS v4.
I have 99swap in system/etc/init.d
I have the .swapfile in /scdard/.swapfile
..the problem is.. I have to manualy activate Swapfile everytime I reboot.. why is the script not working.. when I was on MIUI v5 by maxworks as well same like v4.. it used to work correct..
I have given the system.. the etc.. and init.d folder all access. Read.Write.Execute
Below is MIUI v5 Script that used to work when I used that ROM.
#!/system/bin/sh
#Created by neamv for maxworks. All rights reserved
filename=/sdcard/.swapfile
fsize=256
recreate_on_boot=1
#sleep=120
timeout=240
while [ -z "`mount | grep "sdcard0 "`" ]; do
[ $timeout -lt 0 ] && exit 0
timeout=$(($timeout-10))
sleep 10
done
[ -n "`mount | grep "sdcard .*ntfs"`" ] && exit 0
if [ "$recreate_on_boot" == 1 ]; then
dd if=/dev/zero of=$filename"_new" bs=1024 count=$(($fsize*1024)) && mkswap $filename"_new" && mv $filename"_new" $filename
else
[ -f $filename ] && [ `stat -t $filename | awk '{print ($2)}'` -ne $(($fsize*1024*1024)) ] && rm $filename
[ ! -f $filename ] && dd if=/dev/zero of=$filename bs=1024 count=$(($fsize*1024)) && mkswap $filename
fi

fi
swapon $filename
I didn't want to mess my phone.. so I thougt to ask. Plz automate the process of the Swapfile getting loaded after reboot.. it actually should be created on every boot at a different place in the SD-Card.. this is what I read from Maxworks.
Edit.. One more Question.. If I can.. to make my phone fun faster.. how large should I create the .swapfile.. lets say.. 512MB ?? 1 gb ?? and how to set the swappines.. (and no.. I don't want to use Swapper2)

BUMP

Well, it should work, but may be caused by extensive brake swap. Try chaging the swap size
You can edit the file / system/etc/init.d/99swap replacing in fsize 256 to 64 for example.

[SCRIPT][BACKUP][TOOL]Preserve addon , dpi , Xposed app_process /system files

Hi,
i flash many roms and sometimes after new rom flashed , i see dpi preserved my change before flash, even some rom preserve xposed framework still activated...maybe you have experience with some other backup/restore /system files during flash, maybe have you another idea to preserve some stuff.
For my part, i make a new backuptool.sh and backuptool.functions scripts compiled with some i find over roms i tried....
We have:
save dpi
save xposed framework
save addond
