Application fail to install in android 2.2 - HD2 Android Q&A, Help & Troubleshooting and Genera

First time posting here. hit the problem of not being able to install the game barrr.
Below is the error
Error shown is
E/Vold ( 1529): Error opening devmapper (No such file or directory)
E/Vold ( 1529): ASEC device mapping failed (No such file or directory)
E/PackageHelper( 3452): Failed to create secure container smdl2tmp1
E/DefContainer( 3452): Failed to create container smdl2tmp1
Searched for a few days and finally found a solution from modmymobile forum under motorola milestone development section.
Solution :
go to Settings --> SD card --> unmount SD card.
After that install. That should do the trick.

Thanks mate

I made it in Windows yesterday successfully. There is also a way to flash TWRP on Doogee X3 running Android 6.0.
Look here: http://4pda.ru/forum/index.php?showtopic=713470&st=100#entry51434308
The Problem is, I don't understand russian and I even can't type it. Also the Captcha is a major problem. I think there is an account needed to be able to download the board attachments. Otherwise "404" error. Could anyone Download TWRP for Android 6.0 from this site + the scatter file there ? Would be awesome :highfive:
EDIT: I got it and already installed it. it works ! twrp on doogee x3 running android 6.0. just flash it with sp flash tool. you know how if you had flashed 6.0 already
link: http://www18.zippyshare.com/v/yAM5FXOt/file.html
have fun
EDIT: don't try to root it. doesn't work. neither supersu, kingo root nor kingroot. i tried it and my nvram was corrupt after trying with supersu. had to flash back imei and wifi mac address. i'm back on android 5.1 for this device.
Flashing didnt work,it said coudnt find files or path wasnt right,a red line...
after a wile the flash window got black and wite got frosen,i closed it started to reload and then the flash window didnt showed up and the message in the therminal was ...

[at first for everyone to know: it affects Android 6.0 for the Doogee X3. Android 5.1 is no problem.]
root checker told me my device is rooted after I flashed your zip. The problem I experienced was, I got no asking for root triggered by any app which uses root permission. And also when I try to update SuperSU binary inside the app it tells me there is no "su data" and it couldn't update it. I think to get a flawless root permission it would take a while
SOLVED $mkdir working and than.... $ sudo mount -t ext4 -o loop /img-tools/sys.raw working/
so i did succeed to format the system.img to sys.raw but after trying to mount the sys.raw image i got the following response after the in the tortual suggested command
Am I right that you are already working in the directory "/img-tools" and want to mount the sys.raw file in it ? So then, if you determine to mount "/img-tools/sys.raw" that this could be interpreted as mount "/img-tools/img-tools/sys.raw", a directory that doesn't exist ?
Or am I seeing something wrong ?
i have compiled the system.img file to sys.raw and i want the sys.raw folder so that you can swich framework,apps and other folders with roms to port
i want to have the outcom from the sys.raw ext4 file mounted in the /base home/working folder..
see .http://forum.xda-developers.com/chef-central/android/guide-how-to-port-lollipop-marshmallow-t3283452
mounting system.img should do the job ,so you do not have to format it to sys.raw.
i made a map working in the img-tools map,but with the command below i got ...mount point working/ does not exist
base home/img-tools$ sudo mount -t ext4 -o loop system.img working/
mount: mount point working/ does not exist

I'm more familiar with DOS. But the principle should be the same.
i will try to understand the link you posted...will keep you informed
EDIT: if i'm right, then you are inside the "img-tools" folder and trying with this command to mount system.img to a folder named "working" in it.
e.g.: /base home/img-tools/working
but you want to mount it to the folder /base home/working, right ?
so you have to type it in another way. try: sudo mount -t ext4 -o loop system.img /base home/working/
I'm not sure what Linux expect. maybe the slash before "base home" in my example is not needed.

I sat the whole night to find any supersu which roots flawless our doogee x3 on android 6.0. and i found it ! i flashed, installed, reflashed about hundred of times another supersu version by version downwards. it's the version 2.61 which works properly ! and yes, you can still use the playstore update of supersu + binary update inside the app without losing root or getting a boot stuck. see linked zip for working supersu you'll better save it safely
http://www89.zippyshare.com/v/iUH99ub0/file.html
EDIT: I'm not sure it could be important, but I kept the system partition as read only as I installed SuperSU. Maybe you want to do it also.
i bought a doogee x5 so i am no longer active in this forum

Hiya XDA, So i'm trying to back up my phone (Running CM13) to my memory stick, and it worked before, but now it seems to have broken and I don't know what the issue is. My log (adb pull /tmp/recovery.log) is below

Looks as though your memory stick isn't formatted correctly. Try Fat32 or possibly EXT4
It is Fat32?

I don't have access to a Linux machine, but I could format it in my phone?
I'll try that. and will post any updates.
UPDATE:
Formatted it in Android, still same error
UPDATE 2:
Tried a different USB stick, same error.
The USB sticks I am using are:
amazon.com/SanDisk-Cruzer-Orbit-Drive-SDCZ58-032G-B35/dp/B00BPHTH4C
and
amazon.com/SanDisk-Ultra-Flair-Performance-SDCZ73-064G-G46/dp/B015CH1NAQ/
Remove /system/addon-d in twrp ?
Will my phone work properly after doing that?
UPDATE:
Renamed it to addon-dee in my prefered Filemanager (ES) and it's backing up now.
(thank god I decided to use a USB3 stick this time)
UPDATE 2:
Phone backed up and now is working fine! thanks.
I was having the same error until I updated TWRP to the unofficial 3.0.2-3
I have this problem and l have 17g free space in my internal storage but receive error 255 and i don't find addon in my storage plz help me for fixing this error

Should be under /system/ . Are you rooted? I don't know if you can see that part of system if you're not rooted.
My device is rooted but this file isn't there.

It's not always the same file. Look at your log to see which file/dir is problematic.
SOLVED createTarFork() process ended with ERROR=255
SOLUTION
This solution worked on my Zenfone 3, running lineage Android 7.1.2.
I tried many other things, like flashing different versions of TWRP, deleting the recovery directory, renaming files and all the like.
You may deselect compression, change the TWRP-date / time : nothing works !
You need an PC / Notebook with adb installed.
- start your phone in recovery-mode (TWRP)
- connect to PC and get the recovery.log with following adb command
adb pull /tmp/recovery.log
You will find a copy of the file recovery.log in the directory, from which you started the command
- open an editor or choose your favourite file viewer to open recover.log
- search for the last entry of the word "Error"
- in the line before that, the recovery.log states the name of the file that causes the problem
(in my case it was /system/addon.d)
- disconnect phone from PC.
- restart your phone in "normal" restart (do NOT boot to recovery mode)
- use a root file browser (I used ES-explorer with root enabled) and navigate to that directory/file
- delete the file (which I did not do - I tried some other steps)
- restart phone
This took 3-4 minutes, but I did not delete the file addon.d right away. Instead, I did this:
step 1
navigated to /system/addon.d and copied addon.d to SD-card
step 2
in /system/ , I renamed addon.d "addon_BU.d".
This was successful. In /system/ , the only file visible was now "addon_BU.d"
step 3
tried to create a directory named addon.d inside /system/ because my recovery.log said quote\ ... system/addon.d (not a directory) ... \unquote
FAILED. The directory could not be created by ES-explorer
step 4
copied my backup file addon.d from SD-card back into its original location /system/.
This, I though, would work just fine, because I had renamed the original addon.d to addon_BU.d.
So after restoring addon.d , the only thing left to do would be delte addon_BU.d.
ES-explorer reported no error, but - surprise - there was no file "addon.d" present in /system/
The only file still there was "addon_BU.d"
well, let's go to
step 5
rename addon_BU.d back to it's original name "addon.d" using ES-explorer
FAILED.
addon_BU.d could not be renamed - this file really was screwed up big time !!!
I ended up with no addon.d - so I could have deleted it right away istead of starting my trial with step 1 ...
step 6
Anyway. Shut dowm my phone.
Rebooted my phone normally (not to recovery mode !!!)
This took considerably longer than normal - my heart rate had began to increase slightly if not to say I began to feel like a squirrel on red bull...
After roughly 3 minutes, I had a successful reboot to my OS (lineage Android 7.1.2)
step 7
Reboot again, this time to recovery mode (=TWRP)
and: backups work again.
Don't ask me why this worked and if it will work for you, but hey, give it a triy and let me know...

Hi, thank you for a fix but this is an 10 month old thread. The issue was with TWRP 3.0.2-2. Along with an EFS issue that plagued TWRP 3.0.1-2, both issues have long since been resolved.
Sent from my Nexus 5X using Tapatalk
simple and working solution :
by @yannick818
"looks like it's an error with parallel apps oder multiple users. since i do not use something like that, i just removed this user with the android terminal emulator:
su
pm remove-user 999
everything was fine after that"
I could resolve my nandroid /data backup error on my EMUI 8.0 Mediapad M5 device with those following steps:
1 - Use a correct TWRP implementation
TWRP need to access the uncyphered partition /data.
There no possibility to backup it, if TWRP does not implement deciphering user data partition.
2 - Remove all users except user 0 (the administrator)
You can verify that there is no unwanted users, looking at directory /data/user : the only subdirectory should be "0".
To remove the others users :
Remove the PrivateSpace if you have one (Settings > Security & Privacy > PrivateSpace, and tap on the garbage can).
Remove all the secondary users (Settings > Users & accounts > users, and tap on each users to delete them). Keep just the main administrator user.
On EMUI, remove all twins applications (Settings > Apps & Notifications > App Twin, and disable all twin apps).
On OxygenOS, remove all parallel apps (Settings > Apps > Parallel Apps, and disable all parallel apps).
On MIUI, remove all dual apps (Settings > Dual Apps, and disable all dual apps)
On others devices ... you must find all parameters that create those unwanted users.
If you are not able to get the correct settings to suppress those users, in last resort you can try this command : "pm remove-user user-no. (For example "pm remove-user 999").
3 - Do not forget to protect your backups by a password
This would be stupid to cipher your /data partition and keep backups of this partition unprotected.
These steps fixed the nandroid backup problem for /data partition on my Huawei Mediapad M5 device.
I post on this forum because I hope that this will be helpful for others devices owners.

I tried all methods on this post, but none could resolve my problem.
The first post said Download Aroma file manager on sd card and opt Update from SD card option to install Aroma Filemanager and delete the gesture.key file
I tried installing various versions of the Aroma File Manager app, but all installation aborted with Signature verification failed error having error code:

SM-G950F - Google still thing it is rooted after back to Stock

Hi,
I've been using some custom Lineage with my S8 SM-G950F which worked for for a while and now I'm trying to get back to stock, usually its quite simple download the firmware from Sammobile and flash it with Odin.
I did it and it seem to work perfectly, download the latest version G950FXXSADTI1_G950FOXMADTI1_ITV, my phone is from Italy and bough directly from samsung.
I flashed with Odin 3.14 pointing the 4 files, used the CSC not the HOME one, clean everything, no errors.
I started to install things and after installed most of the stuff I try to add my Credit Cards to Google Pay and it does not let me do it and tell me it is a rooted phone and I could not do add credit cards.
Netflix doesn't even appear on PlayStore to donwload.
Everything works fine, I tried to reflash a couple of times with no success
Only thing strange is when I enter into recovery, it gives me some errors as bellow:
#fail to open recovery cause (no such file or directory)# --> the cause would be me holding keys while starting the phone I believe
Supported API: 3

can't open directory /system/omc/SUP/
....some others similar lines
E:[libfs_mgr]is_dt_compatible() firmware info not valid : '/proc/device-tre/firmware/android/compatible: no such file or directory
IF someone can help me here, I appreciate
Solved, just closed the bootloader.. Silly of me to forget it
Thanks anyway.
