Dumping The XIP Partition - 8525, TyTN, MDA Vario II, JasJam Software Upgradin

How Do I Dump The XIP Partition Of A Hermes ROM? I Read The How to Dump A Hermes ROM And It Labels Two Different Sections As Containg The XIP. So How Do I Get The Right One, I'd Like To Get XIP.bin Like The Huy Who Posted The XIP.bin For WM6 Trinity.
Cheers

First you have to remove 8 bytes every 0x200 bytes from OS.nb, as shown in the attached picture (you can do this with a script using 'dd').
After that, you can use dumprom as usual to extract the XIP section:
mkdir XIP
dumprom.exe -5 modified_os.nb -d XIP

What Script Would I Need For The 'dd' Command?

The shell or perl script you'll write for yourself, so you won't have to repeat the same task more than once ... and Will Parse Your Posting To Convert Every Capital Letter To Lower Case

Something similar to this:
Code:
#!/bin/sh
FILE="$1"
if [ ! -e $FILE ] || [ -z $FILE ]; then echo "missing input file (OS.nb)" ; exit 1 ; fi
len=`/bin/ls -l $FILE |awk '{print $5}'`
pass=$(( $len / 512 ))
skip=512
i=0
touch $FILE.out
while [ $i -le $pass ]; do
if [ $i == 0 ]; then
skip=0
else
tmp1=$(( 512 * $i ))
tmp2=$(( 8 * $i ))
skip=$(( $tmp1 + $tmp2 ))
fi
dd if=$FILE of=$FILE.tmp.$i bs=1 skip=$skip count=512
cat $FILE.out $FILE.tmp.$i > $FILE.tmp
mv $FILE.tmp $FILE.out
rm $FILE.tmp.$i
i=$(( $i + 1 ))
done

cool script pof, but runs slooooowwwwwww...... I'll see if I can code up something to do the massaging for dumprom.

bleh nvm...

need help to translate MIUI V4 (ICS)

Hi,
i tried to translate a MIUI for Galaxy Nexus rom into french (can also be an other language)
i wrote an unix script to automate the process.
What i do is quite simple:
i get a specific MIUI V4 version for my device and the same translated version for the nexus S (because the nexus S has a french version)
i decompile each apk from the french rom, an put the french files into to decompile galaxy nexus directories
i recompile each apk
and i copy the compiled resources into the origin galaxy nexus apks
and i build the new ROM
but i get a bootloop any ideas ?
here is my script
if there are any part of this script that isn't clear, i could try to explain them.
of course this script could also be used on other device or other translation with some changes.
Thanks in advance .

[Q] Need help for executing a script

HI, I'm trying to extract initramfs from zImage by following this excellent thread:
http://forum.xda-developers.com/showthread.php?t=901152
I have followed carefully all the steps but i am getting the following error while executing the extraction script :
# sh repack-zImage.sh -u
repack-zImage.sh: 99: Syntax error: "(" unexpected
How can i resolve this please.
here is the sript :
Code:
#!/bin/bash
version="Version 6, by mizch <[email protected]>
Time-stamp: <2011-05-03 20:14:30 hcz>
Please refer to the thread on http://www.xda-developers.com for
questions and remarks about this program."
# Copyright (C) 2011 by Heike C. Zimmerer <[email protected]>

# it under the terms of the GNU General Public License as published by
# the Free Software Foundation, version 3 of the License. For
# details see <http://www.gnu.org/licenses/>.
### Preparation:
# You should have received cpio_set0 along with this program.
# Copy it into /usr/local/bin.
#
# The program will run without this (and emit an info message about
# using the normal cpio). However, the compession result of the
# initramfs will be smaller and consistent if you use it.
### What the program does:
usage(){
echo "\
Usage: $pname [-v] -u|-p|-z [<file name, default: zImage>]
Function: [Un]Pack a zImage (for modification, mainly of the initramfs)
Opts:
-u unpack an Image
-p pack an image from a directory structure created by
a previous unpack
-z create <file name>.tar from <file name> (simple tar, nothing fancy)
--version print version info
--help print this help
Play with the following three options to get best compression results:
-s use standard cpio (default: uses cpio_set0 if available)
-g use gen_init_cpio instead of cpio/cpio_set0 (ignores -s)
-r don't reorder initramfs according to the original layout
Debugging:
-v verbose (show commands and results as they are executed)
-x script debug (set -x)
Options to help nail down which modified part causes booting to fail.
Lower numbers override higher numbered options:
-1 Use original piggy.gz+piggy_trailer
-2 Use original piggy.gz
-3 Use original piggy
-4 Use original initramfs(_gz)+part3
-5 Use original initramfs_cpio"
exit $1
}

[Q] Debloat script coding

Hello all,
I'm trying to cleanup/simplify some code to debloat a stock samsung rom. Im using osm0sis (https://forum.xda-developers.com/an...-complete-shell-script-flashable-zip-t2934449) shell script to do this:
Code:
STOCK_APPS="ANTHalService
ANTPlusPlugins
ANTPlusTest
ANTRadioService"
debloat_sysapps () {
for app in $(STOCK_APPS); do
if [ -d "/system/priv-app/${app}" ]; then
mkdir -p "/sdcard/stock_backups/priv-app/";
mv "/system/priv-app/${app}" "/sdcard/stock_backups/priv-app/";
fi;
else [ -d "/system/app/${app}" ]; then
mkdir -p "/sdcard/stock_backups/app/";
mv "/system/priv-app/${app}" "/sdcard/stock_backups/app/";
fi;
done;
}
Which when I flash in TWRP, returns error 2. Anyone got any tips/insight on how to make it work?
(Im aware that the usual delete_recursive works, which is what Ive been using usually.)
Thanks in advance,
yass

Guide: Fix WhatsApp Images mess after restoring backup

Hey there
Thought this might help some of you finding yourself in a huge mess because WhatApp restores all its media with the date the restore takes place. I wrote a little shellscript you can run in "adb shell". Just paste it into the shell and run it inside WhatsApps Folders.
In "WhatsApp Images" and it's subfolder "Sent" use this:
Code:
for file in *; do
if [ -f "$file" ]; then
timestamp=$(echo "$file" | sed 's/^IMG-\(.*\)-WA\(...\)\(.\)\..*/\10\2\.0\3/g')
echo $timestamp
echo $file
touch -m -t $timestamp $file
fi
done
For "WhatsApp Animated Gifs" and "WhatsApp Video" use this:
Code:
for file in *; do
if [ -f "$file" ]; then
timestamp=$(echo "$file" | sed 's/^VID-\(.*\)-WA\(...\)\(.\)\..*/\10\2\.0\3/g')
echo $timestamp
echo $file
touch -m -t $timestamp $file
fi
done
Keep the following in mind:
- This code works only if your version of Android allows you to change the modified date of files without root. As far as I know this is the case since Andoid 9
- This code doesn't work if you have files with a WA-Number higher than 0599 as my script doesn't take care to match the number with a proper timeformat.
- This code changes the last modified date of your files like this:
Filename: IMG-20190915-WA0039.jpg
Timestamp: 201909150003.09 -> 20190915 00:03:09

A script to get a random file

Dear developers,
I have an issue in my script switching from Android 9 to 10 (devices from a Umidigi s3 Pro to a Umidigi F2)
I have installed Bosybox App on the first and Busybox Magisk module on the latter
Now the script does not work because the command
list=(`busybox find "$dirs" -type f -name *.$ext`)
returns an empty array
This is the complete script:
Bash:
#!/system/bin/sh
echo
if test "$1" = ""; then
echo "Randomfile script by Uranya <[email protected]> v1.4 01.01.2021"
echo "Usage:"
echo "sh randomfile.sh <sourcedir> <extension> <destdir>"
exit 1
fi
dirs=$1
ext=$2
dird=$3'/'
dest=$dird'random'
delim1=""
delim2=""
last='last.txt'
# create filename's array
IFS=$'\n'
# here we have the ISSUE
list=(`busybox find "$dirs" -type f -name *.$ext`)
# count number of files
num=${#list[@]}
# initialize random generator
RANDOM=$$
# generate random number in range 1-NUM
let "ran=(${RANDOM} % ${num})+ 1"
echo Random from $num files is $ran
sour=${list[ran]}
sourn=${sour#$dirs}
sourn=${sourn:1:${#sourn}}
date=$(date +"%Y.%m.%d %H:%M")
day=$(date +"%d")
hour=$(date +"%H")
minute=$(date +"%M")
message='---------------------------------------\n'$date' - '$num' >>> '$ran'\n'$delim1$sourn$delim2
if ([ "$day" = "01" ] && [[ "$minute" < "29" ]]) || [ ! -f $dird$last ]; then
echo >$dird$last $message
else
sed -i '1i'$message $dird$last
fi
echo $delim1$sourn$delim2
# rename the old file
cp $dest.$ext $dest'_back.'$ext
# copy the file
cat "$sour" >$dest.$ext
echo File copied as $delim1$dest.$ext$delim2
Can you please help me why this happens, and how to fix it?
Thank you very much for your attention!

Click to expand...
Click to collapse
Having done some tests I have found this:
opening a root privileged terminal and executing
---
echo `find /storage/7BC3-1805/Music/MP3/Abba -type f -name *.mp3`
---
it returns two strings containing the names of files inside that folder, but putting it in my script continues to return an empty array, so the issue is not in the access to the folder, but in the syntax, I guess
try putting that *.$ext into quotes...
Dear friends, CXZa, after a couple of hours debugging the script, finally, I have found the mistake!
The line to be used is:
list=( `find "$dirs" -type f -name "*.$ext"` )
it is a very subtle difference: the space after and before the parenthesis!
(even the word busybox is useless)
Oddly in the Busybox app (I have had on my S3 Pro) the spaces are not mandatory, whilst in the Busybox Magisk module those spaces ARE mandatory!
I'm using that script for almost 8 years to have an every day different music for my wake up.
I'm using Tasker to call it just before my alarm get off, so the same file contains every day, a different song.
I have done a change also in the array index that did not began by 0...
So, here it is the right script:
Bash:
#!/system/bin/sh
echo
if test "$1" = ""; then
echo "Randomfile script by Uranya <@uranya7x> v1.5 26.03.2021"
echo "Usage:"
echo "sh randomfile.sh <sourcedir> <extension> <destdir>"
exit 1
fi
dirs=$1
ext=$2
dird=$3'/'
dest=$dird'random'
delim1=""
delim2=""
last='last.txt'
# create filename's array
IFS=$'\n'
list=( `find "$dirs" -type f -name "*.$ext"` )
# count number of files
num=${#list[@]}
# generate random number in range 1-NUM
let "ran=(${RANDOM} % ${num})+ 1"
echo Random from $num files is $ran
sour=${list[$ran-1]}
sourn=${sour#$dirs}
sourn=${sourn:1:${#sourn}}
date=$(date +"%Y.%m.%d %H:%M")
day=$(date +"%d")
hour=$(date +"%H")
minute=$(date +"%M")
message='---------------------------------------\n'$date' - '$num' >>> '$ran'\n'$delim1$sourn$delim2
if ([ "$day" = "01" ] && [[ "$minute" < "29" ]]) || [ ! -f $dird$last ]; then
echo >$dird$last $message
else
sed -i '1i'$message $dird$last
fi
echo $delim1$sourn$delim2
# rename the old file
cp $dest.$ext $dest'_back.'$ext
# copy the file
cat "$sour" >$dest.$ext
echo File copied as $delim1$dest.$ext
I hope it will be useful to someone else that loves to be waked up by music...
Peace everywhere!
