build.prop update.zip

Is it possible to make an update.zip file that replaces the build.prop file, or any way to replace the build.prop file without doing a full restore?

I did it using adb commands.

Well I tried using adb shell to swap the file, but when I ran su I got "[1] + Stopped (signal) su"
So I guess I'm going to be forced to do a nadroid restore of my system

Just use root explorer to copy the file to /sd, then use astro to edit it, and root explorer it back to the original spot and reboot. You don't need to change file permissions or any thing. No computer needed.

Hi Clienterror,
What if the system is not booting?
I had installed an application which changes resolution and now ended up with a boot loop.
I have searched for ways how to extract the build.prop and correct the error, but none appears to exist.
I was asking if it is possible to extract the current build.prop via the update.zip method so that the build.prop can be repaired...
I read that from the update.zip you can execute code, would it be possible to use a similar method for extracting files from the system folder?
Thanks

You could just reflash your current ROM and it should replace it.

Hi korockinout13,
I have tried to refresh from a rom i got, but I am prompted an error with Nand version.
The android in question is not common (Subor, a chinese Android Tablet) and have not found any firmware for my particular model except for the one supplied by the supplier, which still does not install.
At this stage reflashing is not an option, so I am looking for something else...
Thanks for your time

Actually there is a potential option... can you get into recovery? And does your recovery have a file manager? If so go into mounts and mount /system. Then use the file manager in recovery and you should be able to access build.prop. copy it to your SD and then you should be able to mount your SD to your computer through recovery.
Edit: when you mount /system make sure you mount the SD as well or you won't be able to copy to it while you're in the recovery file manager.

Hi m1batt1,
The recovery does not have any file mount option
I have lost all hope of being able to get the system to boot.
Thanks the same.

You might have to flash stock KK4 at this point and go from there.
What kernel do you have for it not to have a file mount? I believe even stock kernel has it Since you can get in download mode, I would flash a newer kernel if I were you (with Odin) to be able to mount in recovery.

From what I'm reading he doesn't even have a captivate. He's using some Chinese tablet.

[Q] what is the new update??

sorry for posting new thread but I don't know where to ask...can anybody please tell me tge new update 4.5.269 and someting3..is it the new version of gingerbread,is it safe to update..please tell me...

The new update is 4.5.629. It goes from Gingerbread 2.3.3 to Gingerbread 2.3.4, so a slight update. There are a few bug fixes, but it has a number of undesirable things.
1) 4.5.629 is currently not rootable
2) You cannot simply return to an earlier version via SBF.
You can overcome the first by using Voodoo Rootkeeper or similar to root on your current version, back up root with Rootkeeper and then update.
Recently, a method was found for this release to unbrick phones damaged by attempts to SBF or from bad ROMs: http://rootzwiki.com/topic/23207-how-to-sbf-unbricking-root-d2g-629 This also allows users who did upgrade to 4.5.629 to return to the previous version, root there and then upgrade again.
So it is sort of safe, but not ideal. The changelog is here, decide if the bug fixes are important enough for the added inconvenience

ok...thank u very much +1..I prefer not to update for now,and by mistake ,i select yes button in the update prompt,and its in the pull down bar,stucked and is ready to start downloading as soon as I connect to wi-fi,how will I cancel the download

You can block the update by renaming these files (e.g., append ".bak" to each filename):
/system/app/BlurUpdater_VZW.apk
/system/app/BlurUpdater_VZW.odex
Since these are in /system, renaming them requires root privileges and a root-enabled file manager (such as Root Browser Lite, available in the Google Play store).

ok..thanks,will do that,but after doing that,will I be able ro manually update it,or all the updates have been blocked???

Renaming those files will disable the OTA update client completely. You can still manually install an update by rebooting into recovery, but you will first have to download the update file from another source, rename it to "update.zip", and place it in the root level of your SD card.
Of course, you can also change those files back to their original names to re-enable OTA updates at any time.

okok..thanks man +1
edit : i got this 'failed to rename file' error ..what should I do??

What app did you use to try to rename the files?
Did you root your phone before attempting the rename? (See http://www.psouza4.com/droid3/ for instructions.)

the app that u suggested me,root browser lite and my phone was rooted and also have been granted superuser's permissions..

You didn't remount /system in Read/Write mode.

please tell me how to do that

Root Explorer has a button for that.
“adb remount” when connected to a PC with USB debugging enabled will do that as well.
It's also possible to do from the terminal emulator, however I don't remember the exact command.

i can't find that button,by long pressing the file/folder or what?

It looks like this app defaults to RW once it gets superuser permission (GY was referring to Root Explorer, a different app). How about copying a system file, does that work?

Editing permissions

I root my phone as a thread
In the site but when I use root Explorer to edit permissions of some
Folders ex: system it says Warning
Permissions change was not successful. Please note that some file systems
(E. G. SD cars) do not allow permission changes
Also I use root Explorer as r-w

what does that mean?

No some permissions are unable to change because it is for safe purposes because you might screw up your phone if you change the permissions or there is a duplicate file of it

I ROOTED the phone by
1.put the phone in download mode
2. Flash CWM by ordin
3. put the phone in recovery mode
4.install zip superuser 3.1.1 arm. Zip
And I want to edit permissions of system folder to copy files to system/bin

ok... i think there is a newer one in development section, with superuser 3.1.3
but i don't know if that is the problem, anyway you can redo the whole process of rooting, starting with flashing stock or you can change the app
i use root explorer and it works nicely, never had a problem with it
another thing you can try is flashing a custom rom, maybe its a firmware problem

I know that, I am not blind, but why do you want to mount it r/w, what you want to edit ?

Explain clearly what you want to do with R/W permission?
Use Root Explorer : https://drive.google.com/drive/u/2/folders/0B9v3aNFonkyMdEtqYks0T0lPc2c

Use fx or ES File Explorer, there should be an option to mount system as r/w

I'm rooted, trying to install Xposed Framework, how do I delete a file from /system/?

I tried installing it with both Flashify and Magisk, but both methods failed.
When I tried installing it via the included Xposed Installer, it also failed, but gave me the message:
> Error: Xposed_Framework.jar already exists in /system/framework
I'm guessing a previous installation failed, but left the file there.
My next idea is to delete that file from /system/framework and try again, but since it's in an RO directory I don't have permission.
I tried using a terminal emulator to mount the drive in rw mode, and also tried using a root file explorer, but either both methods don't work, or I just couldn't figure it out.
Anyone have an idea of how to remove or rename that file so I can try to install the .zip ?
-Thanks

In the Xposed app you should be able to just run the uninstaller script. If that doesn't work, boot TRWP and delete it from there.

Unfortunately, the uninstaller also fails.
It says it can't remove that file from a read only directory..

Root Explorer....
This app does wonders, it allows you to modify directories in /system and other root folders. You can even change permissions of specific folders/files from read/write/read-only....etc. I've had this app since the earliest of android days and it has been my go to file explorer. Root Explorer of course requires root....but it completely unlocks your phone and allows you to modify any system file that is set to any permission. Of course there are other file explorers that allow you to modify system files, but this is the one that i have the most experience with. You should be able to access the system folder where the Xposed file remains and modify it so it can fix your problem.

This!. I've used it for years. Not muss no fuss. It's not bloated like a certain couple others I know of. It just does what it does and does it well. Manages files. No extra garbage.Give it a try. I'd be surprised if you can't delete it with Root Explorer. If you do try it, go to the folder you want to delete the file from. Once in there, look at the top right of the screen. Somewhere up there It will say MOUNT R/W. Touch that and you should be able to do whatever you want to within that folder.

Do you have the magisk DNSCrypt module installed? If so, thats why you cant modify anything in /system. Not sure why or how it breaks it, but it does. Took me for ever to figure out what was causing it. Now that i removed the module, i can modify anything i want again.
