[XPERIA X10 General] Perceval from Hyrule:
FAQ

FAQ​

- Supported devices

It is first developped for Sony Ericsson XPERIA x10, but it should work on any Android device with these requirements :

* Rooted

* File system is mounted Read/Write.

* Build.prop is located into /system/ and named "build.prop"

Sony Ericsson XPERIA x10 : fully working

Samsung Galaxy S2 : half working (file system is read-only...)

- How it's working ?

The script works generally in this way :

It downloads from your device your build.prop and creates two temporary backups.

Then, it opens one of the temporary backup into notepad, to let you edit all you want.

Once file closed/saved, the file is reconfigured automatically, then sent back to your device.

The script allows you next to keep, on wish, the remaining backup and to reboot your device.

- Is this safe ?

The script makes a backup of your build.prop every time you try to access it. There's also human-friendly log file to help you identify problems with ease.

There is also NO automatic upload to your device : the script will always ask you before if you want to upload the new build.prop to your device. Even if you upload it, backup is stored and can even be stored safely on your device for future use.

- Is this all automatic ?

Yes. The script makes backups by itself, reboot your device for you (if you wish), and of course change permissions. But don't worry : it will ask your approval for any important process :)

- The 3G tweak makes my connection unstable !

The Manager is based on my 3G+ enhancement script, using "Full Mode". In the original script, there is also a "Lite Mode" for some networks (like AT&T) I included in v1.3.

To make your network stable, the script will disable the two lines below :

ro.ril.enable.dtm=1 (will be turned to 0)

ro.ril.enable.a53=1 (will be turned to 0)

To get full details about the 3G+ tweak, check the thread :

Why is there "so many" different batch files ?

It's easier for me to improve/maintain the batch by splitting it into different functions. There's a main script, and subroutines called when needed.

Of course, all the subroutines, including addons, are programmed to be run only from main script. You can run any subroutine separately, but it will mostly crash and create useless files not being deleted. Always run the main script, and do no try to run separately subroutine - not dangerous, but 100% useless/buggy.

- It's not working.

* Make sure your device is :

** ROOTED,

** Full external access to system (su command) [if not, will drop errors like "Operations not permitted" or "file system is mounted read only")

** USB Debugging is enabled,

** Connected using USB and all USB drivers are installed/working.

* You might need administrative privileges in Windows to fully run the program.

* If you're running your device from recovery, you may need to mount /system/ folder before running the script (Partition tools > Mount /system).

- It's still not working.

* Drop a message in the official thread.

* If you get errors about file system Read only, try to run your device in Recovery mode, and fix permissions.

- Will the script create lots of files/make a big drive footprint ?

I hate programs creating lots of temp files. So, the script was developped to create files AND to clean/remove them all once everything is done. Even if it crashes without removing files, you just need to restart the script - it will clean all previous temporary files.

If ADB is run, it WILL be fully closed once everything is done. Server will be killed, then ADB process (named adb.exe) will be killed. Your system will be as clean as it was before running the script.

The script is of course fully portable : there's no installation needed. You can put the script where you want, but you just need to keep all script files/folders in the same folder.

In a future release, I'll add something to purge the log file.

- Which OS is supported ?

It's developped in Windows 7 x64. You should be able to fully run it on any 2000+ Windows NT OS.

As it is NT script, it will work only on Windows computer. It will also not work properly on pure DOS (it's using NT commands and Windows-related commands not included in older Windows NT systems, like NT4).

Report if you tested it on other Microsoft OS (NT 4, Windows 95, 98 or 2000, Dos 6.22...) :)

- I wanna contribute.

Just right click the .cmd/bat files, edit them with Notepad or anything you want ;)

You can also send me a message (thread or PM) if you notice some piece of code I can improve with other commands (I don't know DOS commands enough :D )
