How to delete system files while i'm rooted? - General Questions and Answers

Hello everyone, i have a rooted phone GT-I8262 and i used to delete the system apps before by ES Explorer or root explorer, though i'm now facing a problem with a file that i can't delete, it says you have no permission to do it, this app is called (DU battery saver) each time i uninstall it from my phone and restart the phone, it shows me that black screen after the boot logo which is (android is upgrading) so after i open the phone, i see that (Du battery saver) is installed once again.. i had to go to the system files apps folder and couldn't find it there, so i found it in another directory in DATA/APP folder, so i tried to remove it by 2 kind of file explorers like ES and root explorer and after giving them the permission of root. but i couldn't remove it, is there any way to remove such protected apk files?
please help, thanks

[Q] Help needed for bootanimation

Dear all,
I have my eee pad installed with the latest Revolver Rom. I would like to install a custom boot animation. I searched a bit and would like to use ES file manager to create a folder: \Data\Local.
Now, the Data folder is already there but when I try to create a folder, it tells me that I cannot create a folder. I can also not replace the bootanimation under \System\Media.
Is there any way I can get write access here?
You need to allow ES File explorer root access.
Both the data/local and system/media is already there, no need to create any folder. You could also ADB push the file to the location
You can also try an application called Root Explorer (from the market), which works for me. But I've never really used ES File explorer much (there was something I did not like about the UI), so I cannot compare.
Solved!
Thank you for the replies. Indeed, needed to give root access to ES File Eplorer through options in the program.
Cheers!

System "semi" Writable?

I recently Wiped my Phone completely and decided to Re-Flash Viper 1.2.1.
I noticed a problem prior to re-installing but thought nothing of if since it wasn't crucial at the time.
In Root explorer, I am able to delete [i normally delete boot animations] system files but not add where I need to add. Example, I wanted to add a ringtone to my system/media/ringtones folder. I normally [for the last six years] could just copy and paste such files using a root file manager.
However, when I any these files to for example /system/customize/resource/ it doesnt add it. BUT IT DOES rename the file and save it under a dif folder.
Example. Tried copying-copy to-moving to "androidtwirp.mp3" from sdcard to /system/media/notifications and a message pops up saying"notificationsandroidtwirp.mp3 successfully copied-moved to" and it saves notificationsandroidtwirp.mp3 to /system/media/ and it stays there. retrying from that location only results in "notificationsnotificationsandroidtwirp.mp3".
So not only does it rename the file but it saves it in the wrong location. I am at a loss for word. I tried the basics to tryand fix this but i cant seem to hit it on the head.
Thanks!
Edit: Not updating Super SU app, file explorer seems to have worked. Will attempt to duplicate problem to see what actually caused.it.
FOUND IT!
Updating my ES File explorer broke my system writing ability. DO NOT UPDATE is because when you do...
Any file you move, copy/paste to the system will not work properly.
This first happened when I tried to copy and paste a boot animation after I updated ES root explorer. It would rename whatever file i was trying to paste/move/copy over and save it under a sub folder.
example.
copying a ringtone [i.e. androidtwirp.mp3] from SDCard to System folder, the path is /system/media/audio/ringtones/ and it would rename it "ringtonesandroidtwirp.mp3" and save it under /system/media/audio/.
So basically not only was it renamed [which i didnt want it to be] but it would save it to the folder before the actual folder i needed it to be in, plus it would corrupt the file deeming it useless.
moving "ringtonesandroidtwirp.mp3" into the correct folder would only result in "ringtonesringtonesandroidtwirp.mp3"
this happened across the board with all files being moved around
The ES File Explorer version 1.2.1 comes with works flawlessly so don't update it.
I uninstalled ES [also any folders in SDcard related to it] and downloaded JRummy's root explorer and everything is back to normal except i have to reboot the phone to see files [like ringtones and notifications] that i added to the system.
I think it has something to do with our devices having an unlocked bootloaader, but still S-ON. There's S-OFF in the Dev section now if you really need to write to the system folder a lot.
I came from the Vibrant so I know what you're going through
Yeah, im on a low hboot so s-off might not be in my plans since I can practically flash what I want but it was ES file explorer, when I updated the apk the root permissions broke when writting to the system. I emailed the dev and they said they'd have it fixed on the next update.

App to prevent folder deletion?

Hi folks,
hope I'm posting this in the correct place.
I have my DCIM folder on my SD card, and I have deleted the folder instead of an individual photo in the folder several times now.
Is there a way to prevent the deletion of this folder, by locking it or installing an app that will lock the folder, but not hide it or impact the usability in any way?
Change the permission to read only using any file browser like xplore..
Permission cannot be changed unless its a system folder..
The only option is to be careful not to delete any folder you don't want to or download ES File Explorer from the play store and enable Recycle Bin so you can restore back your folder in case you delete them.
I've installed the ES File Explorer, let's see if that does the trick. Thanks!

Chinese Phone running Android 4.2 - Malware built in, cant delete despite root

It took me a while to figure out that the bast**ds had built in the malware in the firmware, with the launcher. Phone is rooted, and I have changed the launcher. But I can't delete the malware apks inside system/app.
They are named as com.google.hardware.ext0.apk, and another similarly named (android air, and measure too)..
Problem is, I can't delete them, I tried using ES File Explorer (yes, root is enabled. I can delete, change other files in system/app but for this) I am denied permission!!
Then I tried the terminal emulator.. after getting SU.. tried deleting them using RM and then 'busybox rm..' both failed. What to do? How to delete the f****ng malware files??
(If I switch on the WiFi, malware automatically downloads more crap, then I can't even switch off Wifi and Data! Hence I formatted the phone and have not entered any sim or wifi settings... but I can't delete the damn files!! Any suggestions please?? Going crazy here)
regards
If you could install a custom recovery to flash a zip that delete this app...
Try a Root System App Deleter or, boot in recovery mode and remove it via ADB

About Easy root for those who have h955 v15c

Hi all, i followed the easyroot system and everything went fine. The flex 2 h955 v15c is properly rooted. Now....tried to use es file explorer to uninstall system apps as i usually do with the other phones but here it is not possible. System apps wont uninstall...so...you are not able to get rid of play books...play games...google+...and other ununwanted apps (at least for me). The question is...if i am rooted why can't i uninstall system apps as i did for years. Does anybody know another way ? Thank you and merry Xmas
After first boot after rooting, open superSU and update it, then reboot and try to use root explorer in ESFile Explorer and you will se popup to alow root acces, grant acces then try to uninstall system apps.
Hi thank you for your suggestion but i did everything you said. Actually the es file explorer is in the list of the superuser app. As a proof of this i can access to the uninstall system apps screen. Now..when i try to uninstall it says that it is imposiible
Did you set r/w permisions on system folder in es file explorer? Select Root Explorer in ES and then Mount R/W, then give RW to /system... If this doesn help, than I don't know
Did everything but nothing changed. Thank aagain for all your help. I cannot even uninstall "normal" apps..not only system apps. I tried with other uninstalling applications but with the same result.
Clear permisions in SuperSu for ES file explorer, clear cache and data for ES, and uninstall, then install again and grant root acces. Dont cost you anything to try
