Howto Fix install issues specifiacally apps that fail with error code -18

NOTE: Root is required
When an application fails to install - even side loads - an error message is logged.
First thing to check is the logcat -> it will point to a secure file issue.
for error -18 it is
smdl2tmp1.asec
this file, and all other *.asec files are in the /mnt/secure/ directory.
If this file cannot be removed by the installing application a failure message results.
to manually remove this file you need a terminal application
android terminal emulator works just fine.

I believe this fix works on most install error codes.

Interesting. Been getting the Error code 18 when attempting to install VitalPlayer. (Vegan Beta1) Folowed your steps to the letter (miss DOS at times) but that folder appears empty. Actually there is no asec folder on either sdcard or sdcard2. Did I miss something? thanks

Are you using a terminal app on the tablet?
this folder does not show up without using a terminal app on the tablet.
once in the terminal app
cd to /mnt/secure/ to see the files. There is no asec folder. The file extension is asec as in *.asec

You bet. Android terminal emulator from the market. At /mnt (via FileManager) there are folders named secure and asec. Both are empty. Notice that when I cd to even mnt/secure I get same message "not found" Verrrrrrrry interesting!

I saw the samething that nothing shows up in any file manager. only in the terminal ls do the files show up.
you should definitely get a not found for mnt/secure as the actual path is
/mnt/secure/asec/
the initial / is the root of the OS. (linux or unix)
so you are looking for a dir under root called mnt -> /mnt
so if you are having difficulty finding the full path break it down into each step, and do a ls to find the next step
ie
cd /
ls
cd mnt
ls
cd secure
ls
cd asec
ls
etc
hope that helps

Permission denied in Terminal
How do I get terminal permissions?

Typically typing su at the $ prompt should bring up the superuser prompt (allow / deny) as seen on screen 3. If not you should be able to go into the superuser app, and specifically add terminal.
once you allow the su request the prompt should change to the
# symbol

That did it. Only difference this time was I added the ls step you suggested (ls same as dir in DOS?) Got to where I needed to be and deleted the *.asec. Thanks.

Exactly
Dos = Dir
Linux, Unix, OsX, Android = ls (small letters)

Awesome little tut
Was having the same issue - but not receiving an error when attempting to install - walked straight through - had to stop in the dir and see the filename to rm but worked like a champ - thanks!

Thanks for this great walk through. I followed it and was able to correct the problem I was having with some installs. I knew intellectually that Android was similar to Linux, but I did not realize how close it is. It is good to see that my Linux knowledge, I know enough to get me into and sometimes out of trouble (Linux Abuser) , can be applied somewhere else.
Thanks again!

Android is actually very close to OsX in the respect that it is gui first, with the BSD base doing the heavy lifting.
Android is linux in the background with a gui first to allow the ordinary user some familiarity. The reason linux on the phone is not popular and linux on the desktop is not mainstream is because the command line gets equal or higher billing.
Google was smart with Android (basically a linux port with java framework) by promoting it as a gui just like iOS even though to truely see all the potential you need to get to the command line.

[Q] make /data backup as img on computer

hey folks I've got a huge problem and I hope someone can help me or forward me to someone who might know!
So I had some very important data on my HTC One on the sdcard folder (/data/sdcard/Android is the specific folder) and I did a little ROM flashing on monday. So far everything went quite brilliant but today I recognised the data was lost so I googled for 3 hours and tried to do an IMG Backup of the whole /data path with the terminal on my mac. It went well so far with the commands
Code:
./adb shell
dd if=/dev/block/mmcblk0p35 of=/sdcard/databackup.img
But the problem is that this command does a full backup of /data which is far bigger than the free 7GB on /data/sdcard where the backup will be saved on. That means it throws errors after half an error of backing up and canceling the process by saving the largest possible file on the sdcard.
Does someone maybe know one of these points:
1) how to specify the path which folder should be backed up
2) backup via mtp
3) transfer the data directly to the computer without saving anything on data/sdcard
I really don't know if this is the right category to post in but I trust in you guys and I think that this is my last chance to maybe save the lost files

I'll just help myself and other users which may have the same problem some time
http://forum.xda-developers.com/gal...emory-data-recovery-yes-t1994705/post34185439
That helped me a lot and I've taken some parts of it. Here is a short version:
This is a little how2 get the raw out of your smartphone partition. As an example I take my htc one m7
1) download Google SDK
2) make sure all drivers of your smartphone are installed (including adb)
3) download cygwin (install to c:/cygwin)
4) download netcat (extract only the nc.exe to c:/cygwin/bin)
5) make sure usb debugging is enabled on your device
6) create a folder for the raw to cygwin (e.g. c:/cygwin/One)
1st step => make the raw file
Install cygwin. in the packages window you need to search for "pv" and "util-linux" in the repo windows. If you don't you will have trouble.
Before you start operating you should know that if you have a display lock you should disable it for the time of the backup process.
Now start up 2 windows of cygwin. The first command in both windows must be:
Code:
$ export PATH="/cygdrive/[B]c/ADB/[/B]sdk/platform-tools":$PATH
the fat marked part is various and depends where you have unzipped the adb so you need to change it for your usage.
Next step is that you need to make a txt file on your device to see the partition table and decide which partition you need to choose. To make that textfile you simply type into one of the cygwin windows:
Code:
adb shell
then:
Code:
su
then:
Code:
find /dev/block/platform/ -name 'mmc*' -exec fdisk -l {} \; > /sdcard/list_of_dev_partitions.txt
then exit shell:
Code:
exit
Now search on the root of your sdcard a file named
Code:
list_of_dev_partitions
. You found it? great! Open it and search for the partitions address you want to backup. In my case it was the whole /data partition with the address /dev/block/platform/msm_sdcc.1/mmcblk0p37
So the next step was to open the tunnel for a disk dump by typing
Code:
adb forward tcp:5555 tcp:5555
then
Code:
adb shell
then
Code:
su
then
Code:
/system/bin/busybox nc -l -p 5555 -e /system/bin/busybox dd if=/dev/[B]block/mmcblk0p37[/B]
And again you need to replace the fat marked part with you partition path or otherwise it won't work! For my HTC One M7 it looks like this /system/xbin/busybox nc -l -p 5555 -e /system/xbin/busybox dd if=/dev/block/platform/msm_sdcc.1/mmcblk0p37
Samsung or LG phones have another path. Always keep that in mind.
Now switch to the second cygwin windows and type
Code:
adb forward tcp:5555 tcp:5555
then
Code:
cd /[B]One[/B]
then
Code:
nc 127.0.0.1 5555 | pv -i 0.5 > [B]mmcblk0p12[/B].raw
fat typings => use your personal data!!!
If you did everything right then your second window of cygwin should display something like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If it says 0 bytes then your partition path is not correct. You may have a typing failure. Check everything! If it works => congrats now go and drink some beer with friends. 27GB take about 2,5 hours to backup!
2nd step => make it workable
When the backup process is done then do following steps on Windows:
1) click start
2) right click on computer
3) click Manage
4) select any storage and click on disk management
5) "add virtual partition"
6) as location enter the path of your raw (select "show all files" )
7) right click on new partition -> initialise
8) select partition table button & hit OK
9) right click on on the partition and make a new volume
10) leave the volume size, select a untaken drive letter, "do not format this volume" -> hit okay
11) open explorer, right click on new volume, quick format it in FAT32
3rd step => recovery!
Now your backup handles like a "broken" SDCard in your computer. For the data recovery I recommend test disk for recovery because you can choose many file formats to recover. You can also try with Piriform Recuva but I had the best results with test disk. That tool is available for many OS :good:

Best run shell commands in Tasker

Hello guys.
I stumbled across a reddit thread providing some run shell commands to replace secure settings. The fixes on Android 6.0 allowed me to install and grand the root permissions but never actually worked as intended. Secure settings still returns errors when used.
Long story short I built on the list adding ones I used before from my list.
Here is about 30 most common run shell commands. I will update list if i come across some new ones. Also appreciate your input if you happen to use some good ones.
You can access it all here:
http://www.notenoughtech.com/tasker/tasker-run-shell-commands/
Happy tasking. :good:

Boy, where do I start? The list would be endless. Anyway, here are some, not all, that I use.
Root commands
Open power menu: sendevent /dev/input/event0 1 116 108 && sendevent /dev/input/event0 0 0 0
Restart SystemUI: pkill -l TERM -f com.android.systemui
Safe reboot: svc power reboot
Safe reboot to recovery: svc power reboot recovery
Get list of all system/global/secure settings along with their values; using system settings as example: settings list system
Read system/global/secure setting to a variable; using secure setting accessibility_enabled as example: settings get secure accessibility_enabled
Change system/global/secure setting; using secure setting accessibility_enabled as example: settings put secure accessibility_enabled 0
Make /system rewritable: mount -o remount,rw /system
Make /system read-only: mount -o remount,ro /system
Change file permissions, using /system/etc/hosts as example; numbers are 7 for rwx, 6 for rw, 4 for r; first number is for root (system user), second is for group, third is for all users: chmod 644 /system/etc/hosts
Tap at x,y pixels on screen, using 540,1500 as example: input tap 540 1500
Swipe from x1,y1 to x2,y2, using 540,1500 to 540,300 (swipe up) as example: input swipe 540 1500 540 300
Read/change another app's database; can't give examples as this would need a full tutorial: sqlite3 /path/to/.db_file "sqlite3 commands";
non-root command
Open any app from a variable %package_name containing com.paclage.name; this one is javascript, not shell script [note that you don't want to put % before variable in javascript]: loadApp(package_name, '', false);
Extract %file zip file to /sdcard: unzip %file /sdcard/
Move a file: mv /original/path /new/path
Copy a file: cp /original/path /new/path
Read a file to a variable: cat /path/to/file
Write %var to a file: echo %var > /path/to/file
Delete a file: rm /path/to/file
Delete a folder and all its contents: rm -r /path/to/folder
Check whether a process is doing something or not; set the output to a variable, set a wait for some time, and then get the output again, if output has changed then the process is doing something: ps | grep com.package.name

Is input keyevent correct for emulating the power button in a shell command? The # on the website didn't work. I found the generic.kl file in my /system/usr folders and the key # for power listed there did now work with that shell command, either. Even with run as root checked.

I've not come across the setting, but try to use:
settings list system
settings list global
settings list secure​and see what your device will give you in options lists.

I totally forgot about another shell command that I have set up in Tasker: md5sum /path/to/file
I use it to verify the integrity of downloads in an OTA app I made for a custom ROM using only Tasker.

[Guide] How to Flash TWRP Recovery on Chromebook

Credits to mauronofrio, nathanchance
My contribution? How do you find that flast flibberen file path?!
This Guide is for Chromebooks only!
You must have your Chromebook in Developer Mode First (please google and search)!!!
To download platform tools / adb or fastboot tools for chromebook (chromebook must be in Developer Mode!!) visit:
https://forum.xda-developers.com/ha...oks/guide-setting-adb-fastboot-x8664-t3806428
then click README
Or just:
1. control + alt + t in a Chrome Browser window
2. type:
uname -m
3. make sure that after pressing enter this shows up:
x86_64
4. if it doesn't show this: x86_64 buy a new chromebook
5. type: shell
6. type:
curl -s https://raw.githubusercontent.com/nathanchance/chromeos-adb-fastboot/master/install.sh | bash
7. then type:
cd ${HOME}/Downloads; curl -s https://raw.githubusercontent.com/nathanchance/chromeos-adb-fastboot/master/install.sh -o install.sh
8. to check if the phone is being seen by the chromebook, type:
adb devices
9. your smartphone device should be listed
10. Done
Next:
Steps to find the correct file path name (Chromebook must be in DEVELOPER MODE!!):
1. download the file that needs to be flashed into the Downloads Folder of your Chromebook
2. control + alt + t in a window in the Chrome browser
3. (without the quotes) type "shell"
4. (without the quotes) type "adb devices" to make sure the phone is attached and can be seen by your chromebook
5. type the command you need, e.g. "fastboot boot," adb, etc.
6. in another tab, take a PDF file from the Downloads Folder and open it in chrome browser
(make sure you go to the Chrome Browser Settings, scroll down and click on "Privacy and Security," then scroll down and click on "Site Settings," then scroll down and click on "PDF documents," then make sure "Download PDF files instead of automatically opening them in Chrome" is toggled Off ((so make sure that the little circle is to the left and Not lit up and colored blue)) to make sure pdfs open in the browser so that you can See the file path name)
7. copy the file path name that is in the url box/omni box and paste it into the shell tab you opened in Chrome Browser in step 2 (I suggest pasting it First into a notes app for future use.)
8. after pasting the file name to where you need it, delete "file:///" or delete the part of the file path name BEFORE "home/chronos..."
9. after "Downloads/" delete the PDF file name and type the name of the file you need to flash so "home/chronos...Downloads/Filename.img" or "Filename.zip"
10. you should have typed into the shell window something similar to this:
fastboot boot home/chronos/u-fhd6557gfh5659h55dg464dyt563652/MyFiles/
Downloads/twrp33170q.img
11. press enter
12. Done
Also, Chromebook must be in Developer Mode!!
My current phone is Oneplus 7 pro and I flashed trwp recovery with my Lenovo chromebook while upgrading to android 10.

Was trying to make it not links on 6 and 7 but whatever.

Try: adb devices instead of "device.." If that doesn't work and your Chromebook is in developer mode and setup right with phone, try sudo adb devices. I'm quite sure it's just a simple typo though and if you use devices instead of device you will be good.

General [SOLVED] Can't copy Titanium Backup files to PC!!!

How can i copy TitaniumBackup folder to PC?
With my others Galaxy phones i always could copy through MTP but with my G998B/DS i can't.
I've used all the methods i found on the internet, such as:
Copy through MTP;
Compress TitaniumBackup's folder into a .zip file;
And through the ADB command
Code:
adb pull "/sdcard/TitaniumBackup" "D:\BACKUP"
Through MTP and compressing the folder i only get the .PROPERTIES files and through ADB i get this error message:
adb: error: failed to copy '/sdcard/TitaniumBackup/com.google.android.apps.photos-20210403-172138.tar.gz' to 'D:\BACKUP\TitaniumBackup\com.google.android.apps.photos-20210403-172138.tar.gz': remote open failed: Permission denied
If anyone can help me I would appreciate it.
SOLUTION: I entered in TWRP and i've been able to copy the folder.​

anyone know how to resolve this? i don't have TWRP so i can't use that work around.

Maybe the "Permission denied" error is triggered by windows itself since you try to copy into the root of drive D. Maybe running your terminal (e.g. PowerShell) as admin will resolve your issue.
Else, @fizmixa , you could still manually boot (but not flash) twrp using fastboot, if your device isn't a Samsung device (I don't know if you can achieve this with Samsung).

Same here...Still couldn't find a solution.

I had the same problem. Looks like it's permission related. I fixed the problem by booting into TWRP -> Advanced -> File Manager, navigating to /sdcard/TitaniumBackup, clicking the blue folder with the tick and then selecting the chmod755 option.
@fizmixa, try and download Terminal Emulator for Android from the Play store and run:
Code:
chmod 755 /sdcard/TitaniumBackup/

It is about owner permission. Tar.gz files has a different owner from .properties. I don't have TWRP recovery because I use Android Emulator. How can I solve this problem?

Same issue here. Is this an Android 11 issue?

I'm struggling with the same issue .. No TWRP with me yet. So any clue how to get these files out of the device ?

They're protected due to security changes in newer versions of Android. I had the same issue on my last device, unable to pull /sdcard/android or /sdcard/TitaniumBackup using ADB for example.
You can try the SmartSwitch Windows app to take a backup of your phone?
Just a word of warning, I used SmartSwitch yesterday and although the backup was successful the call log backup zip was corrupt and couldn't be restored.

Hey, I just managed to sort it out.
Go to Titanium Backup, Preferences, Backup location - and click the below selected option;
Select the external backup storage option, and allow access to it.
It was weird how this caused the PC copying / internal copying to fail .. This sorted the problem for good.

I'm not rooting my S21U but this is good to know for the future, tks.

I'm also having this problem with Android 11 on Pixel 5a, adb: error: failed to copy ...: remote open failed: Permission denied
There isn't a TWRP for this device yet so I can't try that solution. I tried JazonX's idea but it hasn't helped. The problem seems to be that the tar.gz files are owned by media_rw user instead of u0_a252 like the other files. I tried using 'adb shell', "su -" and then "chmod 755 /sdcard/TitaniumBackup/" but it doesn't actually change any of the permissions. Also tried commands such as "chown u0_a252 *.tar.gz" but it doesn't actually change anything. I tried to write to TB support too but no response yet. Any other ideas?

Aha! I found a solution! use "adb shell" then "su -" then navigate to "cd /data/media/0/TitaniumBackup". Now commands like "chown u0_a252 *" actually work and I was able to get full backup of /sdcard/TitaniumBackup with "adb pull". Crazy Android file system!

Did you do this via windows command prompt or within a terminal program on the android device?
As I can't seem to get it to work on Windows CMD
Code:
C:\platform-tools>adb shell
redfin:/ $ su -
redfin:/ # cd /storage/emulated/0/TitaniumBackup
1|redfin:/storage/emulated/0/TitaniumBackup # chown u0_a252 *
redfin:/storage/emulated/0/TitaniumBackup # adb pull "/storage/emulated/0/TitaniumBackup" "D:\Temp"
: adb: inaccessible or not found
127|redfin:/storage/emulated/0/TitaniumBackup # adb pull /storage/emulated/0/TitaniumBackup
: adb: inaccessible or not found
127|redfin:/storage/emulated/0/TitaniumBackup #

I think you have to exit the "adb shell" for further adb commands to work, as "adb" is in your C:\platform-tools directory

I'm having the same problem on my Pixel 5 ("redfin"). It has nothing to do with adb. Without adb running at all, I can go to a terminal emulator on the device and run the following commands ...
Code:
redfin:/ $ su -
redfin:/ # cd /sdcard/TitaniumBackup
redfin:/sdcard/TitaniumBackup # chown u0_a362 *
No error is reported. However, after doing this, all the files previously owned by rw_media are still owned by rw_media. In other words, for those files, the chown command is effectively a no-op, even after an su to root.
Google strikes again with its "We think we're much smarter than you, and we're going to 'protect' you from yourself, whether you like it or not!" attitude.

I know right, it's pretty annoying... but even with root, I think you have to specifically modify the data from the /data/media/0 directory instead, i.e.:
redfin:/ $ su -
redfin:/ # cd /data/media/0/TitaniumBackup
redfin:/data/media/0/TitaniumBackup # chown u0_a362 *
Does that work?

Yep, that worked for me! Thanks! It seems they have put some stupid userland file system which mirrors files from /data:
/dev/fuse on /storage/emulated type fuse (rw,lazytime,nosuid,nodev,noexec,noatime,user_id=0,group_id=0,allow_other)
