Took me a few minutes to figure this out, so I thought to share
This is taken from some scripts I use in CF-Root, you might need to change it slightly for other CWM3 kernels (like prefixing busybox to various commands, etc).
updater-script
Assumptions:
- rootfs is mounted as rw, so we can write temporary files anywhere (ram disk)
- you put a "myscript.sh" in the system folder inside the update
All this script does is extract whatever you have in update.zip/system folder to /tmp/update, and run the myscript.sh file.
Code:
ui_print("Extracting files ...");
package_extract_dir("system", "/tmp/update");
set_perm(0, 0, 0755, "/tmp/update/myscript.sh");
run_program("/tmp/update/myscript.sh");
myscript.sh
Assumptions:
- all busybox commands are symlinked in /sbin, this is usually the case for CWM3 kernels
Code:
#!/sbin/busybox sh
# get file descriptor for output
OUTFD=$(ps | grep -v "grep" | grep -o -E "update_binary(.*)" | cut -d " " -f 3);
# same as progress command in updater-script, for example:
#
# progress 0.25 10
#
# will update the next 25% of the progress bar over a period of 10 seconds
progress() {
if [ $OUTFD != "" ]; then
echo "progress ${1} ${2} " 1>&$OUTFD;
fi;
}
# same as set_progress command in updater-script, for example:
#
# set_progress 0.25
#
# sets progress bar to 25%
set_progress() {
if [ $OUTFD != "" ]; then
echo "set_progress ${1} " 1>&$OUTFD;
fi;
}
# same as ui_print command in updater_script, for example:
#
# ui_print "hello world!"
#
# will output "hello world!" to recovery, while
#
# ui_print
#
# outputs an empty line
ui_print() {
if [ $OUTFD != "" ]; then
echo "ui_print ${1} " 1>&$OUTFD;
echo "ui_print " 1>&$OUTFD;
else
echo "${1}";
fi;
}
# --- example usage ---
# empty line after "Extracting ..." from updater-script
ui_print;
# give the user some status
ui_print "doing something (1 of 4)";
# assume this won't take more than 30 seconds
progress 0.25 30;
# you'd do something useful here
sleep 15s;
# update status
ui_print "- done with something (1 of 4)";
# we're done, make sure the progress bar is at 25%
set_progress 0.25;
# empty line
ui_print;
# repeat this a few times ;)
ui_print "doing something (2 of 4)";
progress 0.25 30;
sleep 15s;
ui_print "- done with something (2 of 4)";
set_progress 0.50;
ui_print;
ui_print "doing something (3 of 4)";
progress 0.25 30;
sleep 15s;
ui_print "- done with something (3 of 4)";
set_progress 0.75;
ui_print;
ui_print "doing something (4 of 4)";
progress 0.25 30;
sleep 15s;
ui_print "- done with something (4 of 4)";
set_progress 1.00;
ui_print;
# done !
ui_print "done! rebooting!";
How, what, why ?
While updater-script is fine for a lot of things, like installing a new ROM and whatnot, anything sufficiently complicated still has to be done through shell scripts, because a great many things just cannot be easily done in edify. It's nice to be able to give the user some status when doing these operations. There are modded versions of CWM that make the same thing possible in other ways, like simply writing to STDOUT or STDERR. This requires either a custom update_binary or recovery binary, though.
This works because communication between recovery and update_binary is through a file descriptor (pipe). Recovery runs update_binary with the FD as command line parameter. Because the shell script is run as a child process of update_binary, it can write the same commands to that FD (commands recovery listens for), because child processes inherited FD numbers and access rights.
So, all the script has to do is figure out which FD to write to, and pass it the right commands. Finding the FD isn't difficult, as it is passed on the command line and so is listed in the output of ps. Some grep and cut magic retrieve it. See the OUTFD=$(...) line. The right commands are defined in the functions at the top.
Note: this is all taken from my rfs<=>ext4 conversion script for CF-Root/ext4. Slightly adjusted, hopefully it still works as expected
Enjoy!
Thank you chainfire

Thanks for this chainfire.
Precisely what I was looking for! You're my hero today, man!
Hi Chainfire
Thanks for your tricks, I'm using it for an almost bulletproof MTD flash script.
BTW, i'd like to call some set_perm commands. But set_perm isn't a recognized command for update-binary.
IDK if I'm clear.
Do you have some advise on that?

I've sort this writing equivalent functions:
Code:
set_perm() { # same as set_perm command in updater-script, for example:
#
# set_perm 0 3003 02750 "/system/bin/netcfg"
#
# sets user:group to 0:3003 and perm to 02750 for the file /system/bin/netcfg
$CHOWN $1:$2 $4
$CHMOD $3 $4
}
set_perm_recursive() { # same as set_perm command in updater-script, for example:
#
# set_perm_recursive 0 2000 0755 0755 "/system/bin"
#
# sets uid:gid to 0:2000 and perm to 0755 for folders and 0755 for files recursively in /system/bin
$CHOWN -R $1:$2 $5
$CHMOD $3 $5
#chmod recursive of folder
$FIND $5/* -type d |while read folder; do
$CHMOD $3 $folder
done
#chmod recursive of files
$FIND $5/* -type f |while read file; do
$CHMOD $4 $file
done
}
There is no error handling (yet), so be carrefull when calling these functions

finding the FD is difficult on an SGY phone under MT 2.0 kernel, because is is not passed as command line param and therefore not in the ps output.
can anyone give an example of a working FD ?
the expression returns "" on my SGY, and no output is readable from script.
above zip as one file with the (.*) business removed from FD expression in myscript.sh
I don't see that ps gives me a "FD" in its output. whatever that really is. /tmp/recovery.log says that /sbin/recovery has no command line params either on SGY
from recov.log:
I:Set boot command "boot-recovery"
Command: "/sbin/recovery"
there is no FD in the command line ! where is it then ?
I'll test this in a bit. Nice hack b/w.
any news?
Thanks for this trick. What I wanted to do is to redirect stdout (and stderr) of my script to the UI. I know that you can see this in "show logs", but I wanted it to display right during the installation. Here is what I came up with:
Code:
#!/sbin/busybox ash
OUTFD=$(ps | grep -v "grep" | grep -o -E "update_binary(.*)" | cut -d " " -f 3);
/sbin/busybox ash $* 2>&1 |
while read -r line
do
echo "ui_print $line" >&$OUTFD;
echo "ui_print " >&$OUTFD;
done
If you save this as "scripts/stdoutwrapper.sh", you can do something like this:
Code:
package_extract_dir("scripts", "/tmp/update");
set_perm(0, 0, 0755, "/tmp/update/stdoutwrapper.sh");
run_program("/tmp/update/stdoutwrapper.sh", "/tmp/update/myscript.sh", "param1", "param2");
In myscript.sh, use any shell commands. The output will be redirected to the UI. Therefore, you should be able to write scripts that work both on the command line and in recovery without changes.
Please note: As all output will be printed, the tricks with set_progress etc. don't work. It would probably be possible to use a prefix to identify commands that should be executed, not printed, so you could do e.g. "echo '<#>set_progress 0.25'".
what value does OUTFD have? find out like below:
adb shell
ps
then /sbin/recovery might have PID 2166 on SGY phone
su
ls -l --color=never /proc/2166/fd
may give you e.g.
3 -> /dev/tty0
so 3 is your OUTFD !
now grep it accordingly for the script. use MT kernel 2.0 on SGY for above capability
time saver
edify Scripts may be tested by executing update-binary directly:
update-binary version output package
An example would be:
update-binary 2 stdout /sdcard/update.zip
Just noticed Chainfire's ui_print shell script in the latest SuperSU zip, and that lead me here.
Here are some updated versions (for CWM6?); ui_print and set_perm from SuperSU and the other 2 from my tinkering today:
Code:
OUTFD=$2;
ZIP=$3
ui_print() {
echo -ne "ui_print $1\n" > /proc/self/fd/$OUTFD;
echo -ne "ui_print\n" > /proc/self/fd/$OUTFD;
}
set_perm() {
chown $1.$2 $4
chown $1:$2 $4
chmod $3 $4
}
show_progress() { echo "progress $1 $2" > /proc/self/fd/$OUTFD; }
set_progress() { echo "set_progress $1" > /proc/self/fd/$OUTFD; }
ex:
show_progress 1.34 0;
ui_print "Hello world!";
set_progress 0.5;
ui_print " "; #blank line
set_progress 1.34;
ui_print "Done!";
Also worth noting he just uses busybox unzip to extract files from the flashable zip directly and goes from there.
ex:
ui_print "Extracting files!"
cd /tmp
unzip -o "$ZIP"

I put ui_print "Test: $OUTFD" in a script and the value of OUTFD appears to increase with every zip flashed.
Not much use knowing it in that case.
Nice work, I used this in my little zip. However, it doesn't work with TWRP. Is there any way to accomplish that?
sorry to put this here but could anyone direct me towards the cwm or TWRP version for "jxjpb" (asia) baseband pls?

TWRP names the extracted update-binary "updater", so you can add something like this (or modify the regex in the existing line):
Code:
[ $OUTFD != "" ] || OUTFD=$(ps | grep -v "grep" | grep -o -E "updater(.*)" | cut -d " " -f 3)

Shouldn't be necessary with any reasonably current recovery. That was just a hack Chainfire wrote to get the FD back in the CWM3 days.
All that should be required (and has always worked for me) is to make the update-binary your shell script, then:
Code:
OUTFD=$2;
See my other updated commands above. And some zips I've made which should provide good references for people: Nexus Louder, Xposed Framework Installer, and Nexus BootUnlocker. All available in my Odds and Ends thread, linked in my sig.

Yes, that works if you replace the whole update-binary with a shell script, but this method is for scripts that are called from the updater-script when using a binary updater.
I've recently switched to a shell script as updater too, but I had to write my own zip signing program because busybox unzip was unable to extract files from a zip signed by SignApk.

Nice! My misunderstanding then.
And ah yes, the old "1 and 8" issue with unzip. Might be resolved in the latest busybox 1.22.1 but I'm not 100% about that, and it'll be awhile before that makes it into recoveries.
I'd love to get hold of your zip signer if that'd be okay. I have Chainfire's solution, but I was still running into some verification problems (I think) from the MinSignApk whole file resigning.

Argh! I saw your original question in that thread but I never found the solution because there were so many pages in between...
I ended up with a hack that appears to resemble Chainfire's minsignapk, but I didn't need to write my own zipadjust. Basically I simply sign the zip normally with signapk, then I unpack and repack the whole archive using 7zip (bonus: slightly better compression), and then I run the whole-zip-signer on the archive.
Here is my SignWholeFile.jar - the source code is just too ugly to publish. View attachment SignWholeFile.jar If you find that it works better than Chainfire's version, I'll clean the source and release it.
This is the script I use for signing:
Code:
#!/bin/sh
KEYDIR=~/android/aosp/build/target/product/security
SIGNAPK=~/android/aosp/prebuilts/sdk/tools/lib/signapk.jar
SIGNWHOLEFILE=~/android/src/signapk/SignWholeFile.jar
java -jar $SIGNAPK -w $KEYDIR/testkey.x509.pem $KEYDIR/testkey.pk8 "$1" "$1.signed.zip"
mv "$1" "$1.unsigned"
signedzip=$(readlink -f "$1.signed.zip")
[ -d /tmp/signapk2 ] && rm -rf /tmp/signapk2
mkdir /tmp/signapk2
pushd /tmp/signapk2
unzip $signedzip
rm $signedzip
7z a -r -mx=9 $signedzip *
#7z a -r $signedzip *
popd
mv "$1.signed.zip" "$1"
java -jar $SIGNWHOLEFILE $KEYDIR/testkey.x509.pem $KEYDIR/testkey.pk8 "$1" "$1"

Without Swap Lite-Version
-Home-Refreshes will be present (but not always!)
-to make your ROM a lite version choose it in install menu!
Flash the CWM partition layout from Mirrors,
Do a backup of SD card,format it and create a SDext and swap(256Mb)
Flash “Dorimanx-Rom-X.X.X-Nightly-XXX-All-in-One !!
Everything will be done by my scripts and ROM
Boot and restore all your stuff and customize it to your personal wishes.
Make a backup via recovery after all to have a backup if you do something bad later.

Enjoy!!
---> This ROM is in constant grow, and Bug find and repair, so if you don't like to flash updates often! then use an other ROM <---
Things to know about ROM
On each boot, you will see Ember Lights blink 3 times and switch to Green!
This is how you know that ROM is loading OK, and there is no boot loop,
When Rom will be almost fully loaded the Green Light will blink 3 times and switch off.
My advice not to unlock phone till you see the GREEN light blink then wait 5 seconds and unlock, this way Home app will load fast and no delays.
When Light blink 3 times green it's tell you that CPU is released and ready for more jobs!
If you see the Ember light again and again and no animation then ROM in Boot loop. (95% will not happen ) I test my ROM many times before upload.
How to update (ROM already installed but not latest version):
Clear cache.
Clear Dalvik cache (not necessary if you don´t have problems dont do it!)
Download and flash new release like usual
REBOOT.
When booted, wait till CPU will be free, 3 green blinks!
REBOOT!!!
No permission fix needed, but if some FC on some apps, do it! and clear there data! should fix all problems.
Be Happy
This is all the GUIDE you need.
Have fun!

About SWAP!
ROM will activate 3 kind of swap
It's will turn ON (only if you have already created swap file on partition, or set partition for swap (the hard way) )
SD-EXT SWAP
SD-SWAP
EXT dedicated SWAP partition
***If you have SWAP already, or EXT or SD-SWAP/EXT-SWAP, no need to run the swap activation scripts.
***I have created 2 scripts for disabling SD swap before use of USB storage.
I have put them in your /sdcard/gscript
so you only need the app (gscript light or full)
then load this scripts, when you need usb storage run swapoff script. when done run swapon.
or you can install dual mount app. i can’t live without it so try it.
Camera!
Camera taking better pick now!
And video recording is with m4v decoder and mp4 file output, video is super! with no lag!
On "HD" camera is on 800x480 6Mbits frameRate="24" Video codec="m4v" fileFormat="mp4"
Sound aac bitRate="96000" sampleRate="16000" 30MB in one minute!!!
On "HIGH" camera is on 720x480 3Mbits frameRate="24" Video codec="m4v" fileFormat="mp4"
Sound aac bitRate="96000" sampleRate="16000" 23MB in one minute!!!
To switch from High to HD just choose HD in camera,
if you switch and no difference in screen size then choose LOW and back to HIGH or HD its will change...
Libaudio Drivers
I have uploaded 5 different audio drivers! (Credit to developers)
You can test them one by one, and if you get phone call bug then use the next one, till you be happy with one of them.

CHANGE LOG
DOWNLOADS FOR BRAVO
This ROM is special, its tweaked to MAX! its super fast and has lots of RAM+SWAP
In order to use this ROM as HIGH END you must know that default AndroidAutoKiller is disabled!
This why it's so stable and home app never refresh,
But you must control your free RAM with app called " System Tuner PRO (was know as process monitor pro) " look for it and you will find it.
Also i recommend to use Advanced task killer pro with system tuner pro!
This app will control your RAM and not let to ROM to overload it self and reboot.
I have excluded all my apps and services that i want to run in RAM all the time and the rest are killed when i turn my screen off! or when no more RAM exist.
This setting is inside this application.
It's best that RAM will always be more then 40MB!
The Light ROM (update) set the auto killer back on line, this will limit you to open only 40 apps + services + system stuff, and after app 41 the home screen will refresh and all big apps in RAM will be closed. this is bug in CM7 not related to me.
I just found a way to disable it. (HIGH END)
I have many tweaks working in this Rom,
CRON script that TASK activation by time set.
it's running script every 10 minutes
Script sit in /sdcard/phonePrioritizer/script.txt
It's contain function called renice.
It's set CPU power priority to apps and services that exist in RAM.
I have tweaked the system services and stock apps to best setting for priority.
you can add custom apps
you can use renice range from -15 (big priority to service / app ) to 15 (very low priority to app / service)
The -20 to -15 reserved for system. do not use it or instability can be felt.
To add custom app to priority script install autokiller from market open your app push home, go to autokiller app and to services ,
find your open app, click long on it and choose more info,
you will see that package name, this is what you need, write it down and go and edit the script.txt according my example at the bottom of the script.
We Are Number One! In NAND ROM NO SENSE!
Keep the feedback flowing, I need to know how it's working for you.!
Lets make best ROM for US!
DON'T FORGET TO PUSH THE THANKS! BUTTON
YOU CAN ALSO DONATE TO KEEP ME GOING!
LOOK FOR BUTTON "Donate To Me" under my nickname!
Thanks for using my ROM!
I am here for you so write comments!
SWAP THE HARD WAY!
What is swap?
Swap is extension or RAM on sdcard, for ability to load more apps in RAM and get fast multy tasking (apps stay in ram)
Many people think that this is not needed any more. well i must disagree it's way better with swap when you don't have any more RAM to spare.
When no RAM Android start to kill apps that sit in RAM and by doing this kills my apps that i use all the time,
So phone loads them again and use CPU power in process and killing other apps!
so it's a circle a loop, with swap no problem!
I have 37 apps in memory all the time.
So here is the guide to activate SWAP on your device The hard way!
Again read about it and only if you think you need it and you are heavy user like me!
Then follow closely to instructions!
1) This procedure will erase your SDCARD!!!
So before you begin backup all your stuff from SDCARD and the extended Linux partition to your computer drive!
You can use Titanium backup PRO to backup all, and then move all to your disk.
And after you finish, restore all back.
2)when you ready to format your SDCARD, Download Recovery_150M_system_5M_cache[v3.1.0.1].zip from my ROM mirror!
unzip to comp and install it, (how to you must know by now)
3)when all done, enter to new recovery console, go to advanced and use the partition sdcard
Choose your preferred size of extended partition, then it's will ask you about the size of the SWAP partition! choose 256MB (the MAX) finish and turn your device OFF.
4)remove your SDCARD and using card reader format the FAT32 partition with 32Block NOT the 4096 by default. (this will increase reading and writing performance)
5)copy your stuff back as was to SD.
6)If your ROM working then proceed to 7 if not install your ROM and after restart install my tweaks.
7)now is the fun part! you have swap activated and working! no need to do any thing more!
Now you should see that you have SWAP of 256MB and 0 Used
Go to terminal and run
free It's will start to grow and shrink automatically depend on your RAM use and be activated on boot!.
SD SWAP THE EASY WAY!
In Easy way Swap you don't need to reformat or even reboot your phone to create swap!
If you installed my ROM and you don't have swap but you want to stay on HIGH END ROM,
Then you can do this to enable SD swap
Download script sdswap200.sh or dataswap250.sh from my mirror.
Run in in GSCRIPT App or copy it to SDCARD root,
Open Terminal:
type this:
Code:
su -
sh /sdcard/sdswap200.sh
OR
sh /sdcard/dataswap250.sh
wait for it to finish!
done you have 200mb of swap! with sdwapscript on sdcard OR 250MB swap on EXT (DATA) partiton
You must have 200mb FREE on sdcard before you run this script! OR 250 on EXT DATA partition.
Every time you reboot swap will be activated! NO need to run script any more.
Real Working Auto Brightness module
Here is the Auto Brightness module that you can configure via Settings ( lights.qsd8k.so )
But You will lose the Blinking Notification Light! it's just will be ON (Red Light) if you have notification, or OFF if you don't.
My settings that work just great for me
After installation go to settings > Display settings > Brightness
And set the Automatic Brightness ON
Then go to settings > CyanogenMod settings > Display > Automatic backlight.
*At Light sensor filter check-box ENABLED
*At windows length use 10sec
*Reset threshold use 400LUX
*Sample interval use 2sec
At Light Levels check-box Use Custom
*Screen dim level use 10
*Edit other levels...
Firs of all : Set number of levels to 7 and push the save & apply, you should see now 7 levels
It's should look like that:
Code:
[B]
Upper = (this is changing automatically when you set all the rest)[/B] [B]
Lower Upper Screen Buttons[/B] [B]
0 14 25 255[/B] [B]
15 149 40 255[/B] [B]
150 224 50 255[/B] [B]
225 499 70 0[/B] [B]
500 999 80 0[/B] [B]
1000 2999 100 0[/B] [B]
3000 INFINITY 250 0 (this is the max level)[/B]
Save & Apply go back <--
*Check-Box the Allow light decrease
*At decrease hysteresis use 50%
Have fun with the setting if you like.
CROND TASKER! MODULE!
I have finally cooked the CROND task service configuration, Thanks to LIT!
I have uploaded file CRON-TASKS.zip to mirror.
Cron will start 2 minutes after Full BOOT!!!
SO HOW TO CONFIGURE IT BEFORE INSTALL!!!!
Open the zip!
in folder /system/etc/int.d
open file 08wcron with notepad ++ of EditPlus (not with notepad)
find this:
TZ=IDT-3
This is the TIME ZONE! it's important!
PUSH THIS LINK!
Find you country in that LINK!
Example!
I see for Israel
Friday, August 12, 2011 at 01:44:22 IDT
Current time zone offset:UTC/GMT +3 hours
So i need to SET! opposite! -3 (WHY? have no idea, but this is the only way)
TZ=IDT-3
Then save and install
WHAT IS IT DO?
First it's will remove the Phone prioritizer app, and save you 60MB ram,
CRON will do this!:
Run the prioritizer script every 10 minutes to speed up the phone!
1-59/10 * * * * sh /mnt/sdcard/phonePrioritizer/script.txt;date > /data/cron-renice;echo "runing script.txt every 10MIN" >> /data/cron-renice
Run Clear file Cache every 4AM!
0 4 * * * sh /mnt/sdcard/phonePrioritizer/reboot.txt;date > /data/cron-clear-file-cache;echo "runing reboot.txt to clear cache without reboot every 4:00AM" >> /data/cron-clear-file-cache
Run Clear RAM Cache every 6 hours day/night to speed up the phone!
0 0-23/6 * * * sync;sysctl -w vm.drop_caches=3;sleep 3;sysctl -w vm.drop_caches=0;date > /data/cron-clear-ram-cache;echo "runing clear ram cache every 6 Hours" >> /data/cron-clear-ram-cache
Clear SWAP and re-enable it back! Release all the LAG cache
(works for HIGH END, no change for LIGHT ROM)
20 4 * * * swapoff -a;sleep 5;swapon -a;date > /data/cron-clear-swap;echo "runing clear swap every 4:20AM" >> /data/cron-clear-swap
Script that hold the tsks above is in /data/data/cron/root (in install ZIP)
when in phone then in /data/cron/root
Examples:
* * * * * sh /sdcard/SOMESCRIPT.sh (this will run the script every minute!)
0 5 * * * sh /sdcard/SOMESCRIPT.sh (this will run the script every 5:00AM)
30 5 * * * sh /sdcard/SOMESCRIPT.sh (this will run the script every 5:30AM)
1-59/30 * * * * sh /sdcard/SOMESCRIPT.sh (this will run the script every 30 minutes!)
There are too many combinations, search google for crontab settings
Also i have packed small script name cron-check.sh it's will go to /sdcard/gscript
so load it with gscript and then you can check the status of CRON!
this is what you will see!
/data/cron-clear-file-cache:Thu Aug 11 04:00:01 PDT 2011
/data/cron-clear-file-cache:runing reboot.txt to clear cache without reboot every 4:00AM
/data/cron-clear-ram-cache:Thu Aug 11 18:06:56 PDT 2011
/data/cron-clear-ram-cache:runing clear ram cache every 6 Hours
/data/cron-clear-swap:Thu Aug 11 04:20:06 PDT 2011
/data/cron-clear-swap:runing clear swap every 4:20AM
/data/cron-renice:Thu Aug 11 21:21:01 PDT 2011
/data/cron-renice:runing script.txt every 10MIN
if you see this with your time, then all ok!
But you need to wait till it's will be executed!
so first you will see the:
/data/cron-renice:Thu Aug 11 21:21:01 PDT 2011
/data/cron-renice:runing script.txt every 10MIN
after 10 minutes,
all the rest after first execution!
To see if cron RUNNING!
crond is installed with the busybox!
in terminal do:
ps | grep crond
you get something like this (after you install configured ZIP)
# ps | grep crond
root 4338 1 2188 420 c00bf130 00008a7c S crond
So have fun with it
All my work will be posted here free for all, i will updat on new tweaks.

MY /BOOT/initrd.gz changes:
init.htcleo.rc (all credits to Tytung!!! i just make some edits)
init.rc (all credits to Tytung!!! i just make some edits)
logo.lge
To Extract the initrd.gz
copy the initrd.gz to sdcard
mkdir /initdir
cd /initdir
cp /sdcard/initrd.gz /initdir
chmod 777 initrd.gz
chown 0:0 initrd.gz
zcat initrd.gz | cpio -i -d
rm initrd.gz
EDIT What you want!
Pack the files back to initrd.gz
find . | cpio -o -H newc | gzip -9 > initrd.gz
you can then use this initrd.gz for MAG ROM (copy to boot inside ROM zip)
Or you need to compile it with the kernel module for CLK!
HOW to Compile CLK boot.img
take the zImage , initrd.gz , mkbootimg, and copy to ANY Linux BOX not the PHONE!!!
i used Centos 5
and winscp to transfer files to linux box.
mkdir /clkboot
Copy all 3 files to /clkboot
cd /clkboot
chown 0:0 *
chmod 777 *
run this:
mkbootimg --kernel zImage --ramdisk initrd.gz --cmdline "console=null" --base 0x11800000 -o boot.img
ls -la
you will see the new boot.img
copy in to main root dir on zipped CLK rom.
i will attach the mkbootimg as zip extract it when copying to Linux box.
also there are 2 more files.
repack-bootimg.pl
and
unpack-bootimg.pl
one of them unpack the boot.img extract the initrd.gz + kernel.gz (create folder with all files only for initrd.gz)
and the repack-bootimg.pl will get all back to boot-new.img (in rom folder it's should be as boot.img)
HAVE FUN!
wWOWOO Im going to test now!! Cant wati but are the recovery partitions in the rom or are they 150 and cache 5?
Edit: Bootanimation is craZY1!!!! really nice one!!
oh and rom fast as lightning!!
Hi man, I download 2.5.0 now, I will try for swap.
Your too fast man, your too fast....
All right lets have some fun
Just flashed new v2.5.0
You have tried the rest now get ready to try the best!
From my HD2 with Dorimanx Nandroid
New sheriff in town, let's play
I do not use the swap,so is that right for me to choose the HIHG-END rom?
err sorry but what does SWAP do?

Swap is a sort of ram exension on SDCARD, so you have "more" ram, so more speed for application.
Dorimanx rom is the fastest rom I have ever tried. It works perfectly but, Dorimanx, you have to quickly update your post with all the things new users have to do for creating swap, manage app in ram and so on, because without that, I thnk some people will be in trouble to use your rom as I am at start of using Hig end.
Edit : Oups...Dorimanx : swap not activated on 2.5.0. Trying swapon -a : answer /etc/fstab no such file or directory...Mistake is mine or yours?
the only tweaks that i need for cm7 is tablet tweaks(the soft keys) with percentual battery and your skin(great lookin theme).. it is possible to install Framework-res-TabletTweak-130711+MY-SKIN.zip with Typhoon 3.4.0 or it is not compatible ?
Manual Network selection does not work..it says "Error while searching for networks". This is of much importance to me as i live close to Croatian border and their signal is stronger in certain places in my home.
Other than that, this rom just flies!

OK this is good feedback!
You are using the CLK i guess!
Then something wrong with kernel.
I will revert back to STABLE one that working for all.
I will post new CLK ROM soon.
Thanks!
Thanks for the rom been trying it out and most of it works I just get random reboots on the 2.4.6 other than that all seem well. I will be updating to latest and hope it will go away.
On a side note is there any way you can make that we can revert to stock theme??
Toda for taking the time to help us all out.

What size must have a swap partition? 2x RAM?
I am running on clk with 2.5.0 and I also have swap partition (created through CWM as in your description), but since 2.4.6 and also in 2.5.0 when I type "free" I have "0 0 0" for swap partition, also /system/etc/fstab" doesn't exist.
I did a completely clean installation of 2.5.0, no data partition, nothing.
Any idea?
Update: I now have the swap file by executing your "swap.sh" file from your instructions page. But I thought, this isn't neccessary with your own roms?

Have busybox? Wish you could type "grep foo" instead of "busybox grep foo" ? This simple shell script checks your busybox for supported commands and softlinks them from /system/bin to wherever the first busybox it finds in the $PATH is.
Since I screwed up my links a couple times making this, there's also a script that strips every link to busybox out of /system/bin.
These scripts do basically no error checking. They require root access, but they don't check for it. If you don't know how to read a script to see what it does before you run it, don't run it.
That said, it's handy.
Code:
#!/system/bin/sh
# linky.sh: softlink busybox to all the commands it supports
# Now with zero error checking! Beware :P
# -speef
busybox &>/dev/null || exit 1
bbl=`busybox which busybox`
ready=0
busybox mount -o rw,remount /system
>./linky.log
for cmd in `busybox`
do
cmd=`echo $cmd|busybox awk -F, '{print $1}'`
if [ $ready -eq 0 ]
then
if [ $cmd == "functions:" ]
then
ready=1
continue
else
continue
fi
fi
echo ln -s $bbl /system/bin/$cmd
busybox ln -s $bbl /system/bin/$cmd &>> linky.log
done
busybox mount -o ro,remount /system
echo "see ./linky.log for errors!"
And its counterpart, which removes all links to busybox from /system/bin:
Code:
#!/system/bin/sh
# delinky.sh: remove all busybox links from /system/bin
# Now with zero error checking! Beware :P
# -speef
busybox &>/dev/null || exit 1
busybox mount -o rw,remount /system
for cmd in `busybox find /system/bin -type l -exec ls -l \{\} \; | busybox grep busybox|busybox awk '{print $6}'`
do
echo rm /system/bin/$cmd
busybox rm /system/bin/$cmd
done
busybox mount -o ro,remount /system
First, I'm on Carbon ROM (13/11 Nightly) and Plasma Kernel 2.02. I noticed it had the frandom module (and was probably linking it to /dev/random and /dev/urandom too, since /dev/random.ori and /dev/urandom.ori existed. But since every entropy checker ever was showing 4096 constant, I suspect it linked both to /dev/erandom. To work around this, I wrote the following init.d script (named 20frandom):
Code:
#!/system/bin/sh
if [ -e /dev/frandom ];
then
mv /dev/random /dev/random.orig
ln -s /dev/random /dev/frandom
fi
if [ -e /dev/erandom ];
then
mv /dev/urandom /dev/urandom.orig
ln -s /dev/urandom /dev/erandom
fi
(Yes, I did put an empty enter there). I set permissions to rwx for user and r-x for others with root explorer. I tried executing the script (worked fine), ls showed the extra .orig files, but root explorer would constantly crash. Tried rebooting, bootloop. Deleted the init.d script from recovery, we're back!
But is there some unwritten rule I'm breaking here? Why the bootloop?
I've seen lots of people saying its not possible to make the shield an all in one solution for downloading, but after hours of tinkerering I've got a semi easy way of running the above services (and tons more) from the shield. This does requrie a bit of command line-fu , but I think I've got most of the hard work done. When its all said and done, we'll have a working entware-ng installation ( https://github.com/Entware-ng/Entware-ng)
--This guide is a work in progress, there are a few other items I'll add that will improve user experience, but as it stands now it should work as intended. I also haven't gotten a samba config to work yet, so if anyone can figure it out, let me know and I'll update a section on it
I've addapted this guide from a few github projects , but that likely means some commands/steps are actually useless on the shield:
https://github.com/erichlf/AndroidSeedBox
(will add other sources later)
AS ALWAYS MAKE A BACKUP OF DATA -- I AM NOT RESPONSIBLE IF YOUR DEVICE LOSES DATA (to my knowledge, there is no risk of bricking your device doing this, at worst a factory reset/reflash)
Pre-reqs:
Shield has to have ROOT
ADB set up on PC
Busybox : http://www.apkmirror.com/apk/jrummy-apps-inc/busybox-for-android/
Rom Toolbox Lite : Not on apk mirror, so side load from your favorite place
For this process, I recommend having your shield next to your computer, and share inputs with your monitor. You can do 90% of it from an ADB shell, but a few parts you will need to use a terminal on the shield itself, and keyboard is way easier than controller
Install Busybox on the shield, but use the oldest version available (I think the wget for 1.26 messes with the process)
run "ADB Shell" and run these commands on the shield (You can copy/paste multiple lines into the cmd window):
Code:
su
mount -o rw,remount /
ls /data/entware-ng >/dev/null 2>&1 || mkdir /data/entware-ng
cd .; ln -s /data/entware-ng /opt
ls /data/entware-ng/rootbin >/dev/null 2>&1 || mkdir /data/entware-ng/rootbin
cd .; ln -s /data/entware-ng/rootbin /bin
ls /data/entware-ng/rootlib >/dev/null 2>&1 || mkdir /data/entware-ng/rootlib
cd .; ln -s /data/entware-ng/rootlib /lib
ls /data/entware-ng/tmp >/dev/null 2>&1 || mkdir /data/entware-ng/tmp
cd .; ln -s /data/entware-ng/tmp /tmp
ls /data/entware-ng/home >/dev/null 2>&1 || mkdir /data/entware-ng/home
ls /data/entware-ng/home/root >/dev/null 2>&1 || mkdir /data/entware-ng/home/root
ls /data/entware-ng/home/user >/dev/null 2>&1 || mkdir /data/entware-ng/home/user
chmod 0755 /data/entware-ng/home/root
chown root.root /data/entware-ng/home/root
chmod 0755 /data/entware-ng/home/user
We've set up our staging area, and created a new home directory.
Now lets install Entware
Code:
ls /data/entware-ng/bin >/dev/null 2>&1 || mkdir /data/entware-ng/bin
ls /data/entware-ng/lib >/dev/null 2>&1 || mkdir /data/entware-ng/lib
ln -s /system/bin/sh /bin/sh
wget http://pkg.entware.net/binaries/armv7/installer/entware_install.sh -O /data/entware-ng/entware_install.sh
sh /data/entware-ng/entware_install.sh
Now lets install a new Busybox and Wget
Code:
/opt/bin/opkg install busybox
/opt/bin/opkg install wget
cd /bin; ln -s /data/entware-ng/bin/busybox sh
cd /bin; ln -s /data/entware-ng/bin/busybox echo
cd /bin; ln -s /data/entware-ng/bin/busybox rm
cd /bin; ln -s /data/entware-ng/bin/busybox rmdir
cd /bin; ln -s /data/entware-ng/bin/busybox sed
cd /bin; ln -s /data/entware-ng/bin/busybox mkdir
cd /bin; ln -s /data/entware-ng/bin/busybox head
cd /bin; ln -s /data/entware-ng/bin/busybox sort
cd /bin; ln -s /data/entware-ng/bin/busybox dirname
cd /bin; ln -s /data/entware-ng/bin/busybox ln
cd /bin; ln -s /data/entware-ng/bin/busybox mv
cd /bin; ln -s /data/entware-ng/bin/busybox cat
cd /bin; ln -s /data/entware-ng/bin/busybox chown
cd /bin; ln -s /data/entware-ng/bin/busybox chmod
cd /bin; ln -s /data/entware-ng/bin/busybox pgrep
This next step may be optional. Sets up resolv.conf (which may already exist, I'm not sure) and mtab (I don't know what this is)
Code:
echo nameserver 8.8.8.8 >/data/entware-ng/etc/resolv.conf
ls /etc >/dev/null 2>&1 || mkdir /etc
mount -o rw,remount /system
ls /etc/resolv.conf >/dev/null 2>&1 && rm /etc/resolv.conf
cd .; ln -s /data/entware-ng/etc/resolv.conf /etc/resolv.conf
cd .; ln -s /proc/mounts /etc/mtab
Create Passwd file
Code:
echo root:x:0:0:root:/opt/home/root:/bin/sh >/data/entware-ng/etc/passwd
echo shell:x:2000:2000:shell:/opt/home/user:/bin/sh >>/data/entware-ng/etc/passwd
cd .; ln -s /data/entware-ng/etc/passwd /etc/passwd
echo root:x:0:root >/data/entware-ng/etc/group
echo shell:x:2000:shell >>/data/entware-ng/etc/group
cd .; ln -s /data/entware-ng/etc/group /etc/group
echo /bin/sh > /etc/shells
echo PATH=/usr/bin:/usr/sbin:/bin:/sbin:/system/sbin:/system/bin:/system/xbin:/system/xbin/bb:/data/local/bin > /etc/profile
echo export PATH >> /etc/profile
OPTIONAL: If you want to use Open SSH with password instead of certs you can do the following step. I have done this, and haven't noticed any issues, but it may lessen the security of Root
Code:
/data/entware-ng/bin/busybox passwd root
Now let's create a script that will initialize Entware-ng after reboot
Code:
echo \#\!/system/bin/sh > /data/entware-ng/entware-init.sh
echo mount -o rw,remount rootfs / >> /data/entware-ng/entware-init.sh
echo ln -s /data/entware-ng /opt >> /data/entware-ng/entware-init.sh
echo ln -s /data/entware-ng/rootlinb /lib >> /data/entware-ng/entware-init.sh
echo ln -s /data/entware-ng/rootbin /bin >> /data/entware-ng/entware-init.sh
echo ln -s /data/entware-ng/tmp /tmp >> /data/entware-ng/entware-init.sh
echo ln -s /system/bin/sh /bin/sh >> /data/entware-ng/entware-init.sh
echo mount -o ro,remount rootfs >> /data/entware-ng/entware-init.sh
chmod 755 /data/entware-ng/entware-init.sh
Now lets create a start script that calls the initialize script we just made, but also returns a shell in the new environment
Code:
echo \#\!/system/bin/sh > /data/entware-ng/start.sh
echo ls '/opt >/dev/null 2>&1 ||' su -c /data/entware-ng/entware-init.sh >> /data/entware-ng/start.sh
echo export PATH=/opt/sbin:/opt/bin:/opt/rootbin:/opt/local/bin:/system/bin >> /data/entware-ng/start.sh
echo if busybox test $(busybox id -u) = 0; then HOME=/opt/home/root; else HOME=/opt/home/user; fi >> /data/entware-ng/start.sh
echo export HOME >> /data/entware-ng/start.sh
echo '/opt/etc/init.d/rc.unslung start' >> /data/entware-ng/start.sh
echo /bin/sh >> /data/entware-ng/start.sh
chmod 755 /data/entware-ng/start.sh
Now, lets install different services. These are optional, and there are tons more, but this will get transmission/sickbeard/ssh going
Code:
PATH=/data/entware-ng/bin:/bin /data/entware-ng/bin/opkg install vim
PATH=/data/entware-ng/bin:/bin /data/entware-ng/bin/opkg install samba36-server
PATH=/data/entware-ng/bin:/bin /data/entware-ng/bin/opkg install transmission-web transmission-daemon-openssl
PATH=/data/entware-ng/bin:/bin /data/entware-ng/bin/opkg install python
PATH=/data/entware-ng/bin:/bin /data/entware-ng/bin/opkg install python-setuptools
PATH=/data/entware-ng/bin:/bin /data/entware-ng/bin/opkg install python-pip
PATH=/data/entware-ng/bin:/bin /data/entware-ng/bin/opkg install python-cheetah
PATH=/data/entware-ng/bin:/bin /data/entware-ng/bin/opkg install openssh-server
Copy the start.sh and sysinit to the home environment
Code:
cp /data/entware-ng/start.sh /data/entware-ng/home/root/start.sh
cp /data/entware-ng/start.sh /data/entware-ng/home/root/sysinit
chown root.root /data/entware-ng/home/root/start.sh
chmod 755 /data/entware-ng/home/root/start.sh
chown root.root /data/entware-ng/home/root/sysinit
chmod 755 /data/entware-ng/home/root/sysinit
mount -o ro,remount /
mount -o ro,remount /system
Start the new environment
Code:
sh /data/entware-ng/home/root/sysinit
SICKBEARD CONIG
Install a few pre-reqs for sickbeard
Code:
pip install transmissionrpc
pip install cherrypy
Create a file in init.d to allow sickbeard to start on reboot. Please note, you will need to change the path to where your sickbeard directory is.
I'm not going to cover setting up sickbeard, there are other guides for that. I did find that it couldn't be bound to 0.0.0.0 , or local host, it needed to be hard coded for the shields IP, so I recommend setting it up as a static IP in your router.
Code:
echo PATH=/opt/bin:/opt/sbin:$PATH > /opt/etc/init.d/S96sickbeard
echo /opt/bin/python <YOUR PATH TO>/SickBeard.py -d --port 8081 >> /opt/etc/init.d/S96sickbeard
chmod 755 /opt/etc/init.d/S96sickbeard
chmod +x /opt/etc/init.d/S96sickbeard
OPENSSH CONFIG
OPTIONAL - If you want to use SSH we need to generate keys
Code:
ssh-keygen -f /opt/etc/ssh/ssh_host_rsa_key -N '' -t rsa
ssh-keygen -f /opt/etc/ssh/ssh_host_dsa_key -N '' -t dsa
ssh-keygen -f /opt/etc/ssh/ssh_host_ecdsa_key -N '' -t ecdsa -b 521
Now you'll have to get on the shield and use a terminal emulator to edit your sshd_config file. Here's a copy of mine, but I do not promise how secure it is.
Code:

TRANSMISSION
You'll have to configure your transmission settings, but they're located
/opt/etc/transmission/settings.json
Persist after reboot / Start Transmission/SSH/Sickbeard on boot
On the shield, open Rom Toolbox lite, and go down to "Scripter"
Import the sysinit script located /opt/home/root/sysinit and set the script to run at boot as root
Reboot and you should be able to connect via SSH, and have
Why do we need the passwd and group file ? Won't we use android's UID/GID ?
Can this method somehow be used to create custom group where we could put android's UID ?
I don't know why that step is needed, I got it from the guide I listed, and it worked without any apparent issues, so I left it in. My guess is openssh wants it to be there, but I'm not sure

It would be running on <shield IP>:8081 which you could access from the shield, or any other device on your network. Transmission would be :9091
Thanks for this. I'm trying to get python3-pip, acd_cli, and encfs installed on my Shield TV so I can mount my Amazon Cloud Drive and decrypt files for use with Plex. I have this set up on my NAS but it is too weak to do transcoding. I did set up the NAS as a middleman and mounted shares from it on the Shield TV, and while it does work, the extra step is really slow.
edit: I managed to get acd_cli working but I cannot mount my Amazon Cloud Drive share, I get I/O errors when I try to cd into it. Wonder if there's a kernel issue.

Not specifically. I would think it would have been listed as a dependency and automatically installed, libfuse was though. I ended up factory restoring my Shield after I botched something, so now I'm just at 5.1 stock using the built-in Samba for now.
which version of busybox works? I am having trouble with wget and I tried v1.21.0

In my quote there has to be something missing between the "first" and "second" steps and the "third" one.. are the two files we've just made the missing files in the home/root directory? Or where they supposed to come from somewhere else?
Also the "fourth" step, there are no /data/opt directory in my installation.

Ah! Sorry for not replying until now, life has been busy.
You are correct, there are some typos / things out of order! I'm going to go through this and fix it and will update the OP
I've taken this guide and installed rTorrent (due to superior web client and RSS capability). If anyone needs help on that, I can chime in.
Great tuto !
Working fine one Nvidia Shield TV 2017 with latest update (whithout reboot)
But after reboot I lost /opt and /bin on root :-O
mkdir /opt working fine after mount -o rw,remount /
but if i reboot it disappear
any idea ?
android.stackexchange.com said:
(root) directory is not a persistent filesystem on Android. It's a initramfs, which is packed into the boot image on your device. Although you can remount it with write permissions, changes will always be lost the next time you boot because the original ramdisk will be re-extracted from the boot image on the next boot.

So we need to :
$ mkboot boot.img /output-folder
$ cd /output-folder
$ gunzip -c ramdisk | cpio -i
... make some changes in the ramdisk and possibly /output-folder/img_info ...
$ find . | cpio -o -H newc | gzip > newramdisk.cpio.gz
$ cd ..
$ mkboot /output-folder newboot.img
If you're rooted, a better solution is to simply install in a chroot, either using debootstrap or other; you can obtain a nearly complete Linux system this way (init in a chroot is weird, stuff like openssh will still have to be started separately after boot, either manually or by an app/script).
If you're not rooted, you can use proot for simple path redirection; this is how termux installs arch on unrooted devices.
Using either option (chroot, proot) requires having binary files that aren't in a noexec partition; generally this means private app storage, not sdcard that's accessible to other apps. If you're building a chroot, you should be able to include the external/public storage folder in it, however a chroot also requires the partition not be mounted with nodev option.
***Note that I don't actually have a shield TV*** (I'm just interested in getting one) so I can't say if the shield's storage is mounted noexec, but the android data partition generally is. I can, however, verify that the process in general works on Android, however, as I've got two tablets running Lineage/Nougat with chroots, and a stock Moto G6 with archlinux arm in proot. To check for partitions mounted as nodev or noexec, run `mount|TERM=xterm grep --color -E 'nodev|noexec'`. You might check to see if you can use /data/local instead of app's private storage.
For installing BusyBox, *should* be a `busybox --install -s [DIR]` option that copies the binary to the destination, then symlinks applets. This should be simpler than symlinking a bunch of applets manually.
If you want a system-wide BusyBox I recommend stericson busybox: https://play.google.com/store/apps/details?id=stericson.busybox
For a terminal emulator on Android, I highly recommend termux, which is available on Google play and F-Droid. It has support for 256 color, styles, a package manager, Android integration (ie notifications from Linux scripts), boot scripts, widgets, etc: https://play.google.com/store/apps/details?id=com.termux
Another alternative: you can set up user-mode Linux for something closer to virtualization, but I have yet to see any UML binaries for use with Android; this would also make it difficult to run networking and to access files from outside the guest, but will provide a full working system with init support, and would not require root to set up and run--however, I think UML networking requires root and/or kernel support, though, and UML generally requires a disk image much like other virtualization tools. Qemu might be workable instead of UML with fewer issues.
Note that all of these solutions are still running under an Android app, and as such are subject to the android task killer. Not sure if there's any way around this without having something run directly by Android's own init system.

If you're rooted, a better solution is to simply install in a chroot, either using debootstrap or other; you can obtain a nearly complete Linux system this way (init in a chroot is weird, stuff like openssh will still have to be started separately after boot, either manually or by an app/script).
If you're not rooted, you can use proot for simple path redirection; this is how termux installs arch on unrooted devices.
Using either option (chroot, proot) requires having binary files that aren't in a noexec partition; generally this means private app storage, not sdcard that's accessible to other apps. If you're building a chroot, you should be able to include the external/public storage folder in it, however a chroot also requires the partition not be mounted with nodev option.
***Note that I don't actually have a shield TV*** (I'm just interested in getting one) so I can't say if the shield's storage is mounted noexec, but the android data partition generally is. I can, however, verify that the process in general works on Android, however, as I've got two tablets running Lineage/Nougat with chroots, and a stock Moto G6 with archlinux arm in proot. To check for partitions mounted as nodev or noexec, run `mount|TERM=xterm grep --color -E 'nodev|noexec'`. You might check to see if you can use /data/local instead of app's private storage.

Using chroot isn`t good solution. Emulators not effective too.
Stericon`s busybox is paid, meefik`s busybox is free and has more utils.
Termux is heavy, I use Teeminal Emulator: https://f-droid.org/app/jackpal.androidterm
You be able to install a lot of lightweight linux utils by installing entware-ng. For example, git pkg has 300 Mb size in termux and 15 Mb in entware.
Entware has a lot of conmon with optware and openwrt
this is a wonderful guide I'm surprised more people don't use it great job!
