[Q] Changes in build.prop do not save - XPERIA X8 Q&A, Help & Troubleshooting

I have GingerDX installed on a stock kernel. My ro.product.manufacturer in build.prop says "Sh!tEricsson" and I wanted to change that, cause now I can't install Sony Ericsson Backup&Restore and can't restore a backup where all my contacts are saved.
Anyway, it looks like the changes I make do not save. I've followed all steps in tutorials - mounted /system as R/W in Root Explorer, changed permissions to 'write' for group and others before making changes (and changed back after saving). I press 'Save' or 'Save and Exit' and it's all fine. Then I change the /system back to R/O. I can reopen build.prop it in any other file editor and the change is still there, but SE B&R still says I don't have a Sony Ericsson product and after a reboot the ro.product.manufacturer line is reverted back to "Sh!tEricsson". I've tried Root Explorer, ES File Explorer, Prop Editor and BuildPropEditor, nothing works. Any ideas?

Check /system/bin. Some roms have a build.prop there that you also have to edit.

Yes there are 2 build.props..
One in /system and other in /system/bin.
you have to edit them both to change your build.prop successfully...

Thanks for a quick reply guys! I had no idea about the second file. Everything works now, cheers! :highfive:

Swype on Gtablet

First of all, make a backup!! I am not responsible for the terrible things that can happen to an android device when things go awry lol....
Secondly, I have only tried this using Vegan rom (beta 4, and beta 5.1)... I am assuming it will work with any alternate rom but NO PROMISES!!
TO OBTAIN THE NEEDED FILES:
1) Do a google search for "swype on gtablet (kinda)"
2) Somewhere the search results (it was the very first one when I did the search), you should see a post on the tegratab.com forum entitled "swype on gtablet (kinda)" (posted by rothnic)
3) Download the package on that forum, and extract it. There should be three files located in this package: swype.apk, libswypecore.so, and build.prop.
**Keep the page open as we are also going to use the top of the build.prop file that rothnic posted there!! THANK YOU ROTHNIC!!!!!
INSTALL METHOD USING ROOT EXPLORER
I would complete these steps entirely from your gtab, as it does away with the need to transfer files from a pc, etc!
1) Using root explorer, copy first the swype.apk file, and paste it to \\system\app. Once it is copied, long press on it and click "permissions". The permissions should be set as follows:
Read: Check all three boxes down (for user, group, and others).
Write: Check the first box (for user)
Execute: Check the first box (for user)
2) Now again using root explorer, copy the libSwypeCore.so file, and paste it to \\system\lib. Make sure you mount the \\system\lib folder as "read/write" before copying. Once it is copied, set the permissions exactly as you did for the swype.apk file. Make sure you mount the \\system\lib folder as "read only" again before you exit.
3) Now its time to edit the build.prop file, only we are going to make it easy. Instead of going through and editing it, copy the top of the file that rothnic posted on the tegratab site, and replace the top of your build.prop file with what he has there. Don't edit it or anything, just copy it word for word. I did this in root explorer by doing the following:
Using Root Explorer, browse to \\system. Once in this folder, mark it as "read/write".
Locate the build.prop file, and long press on it.
Select "open in text editor".
Copy the text that rothnic had in the post on tegratab, and use it to replace the text that already exists there at the top of the file. It will fit exactly as the original one that you are replacing did. DO NOT CHANGE THE BOTTOM OF THE FILE AT ALL!!!
When you have copied the text, press the "settings" button, and press "save and exit".
(FYI, I am using Vegantab beta 5.1, and replacing the top of the build.prop file did not do any damage to the tablet at all)
Now restart the tablet.
When the tablet restarts, long press on any text entry field and press "input method".
Swype should be an option. Select it, and start swyping!!
If swype isn't listed, click settings, language and keyboard. Check the box next to swype.
(this will also be a good time to click on swype settings and DISABLE audio feedback, as it will drive you and everyone around you NUTS!!)
Now follow the steps above to set swype as your input method and enjoy!!
INSTALL METHOD USING TERMINAL (Courtesy of Terrypchan)
This can be done without root explorer, BUT you have to be willing to type commands in a terminal emulator. I did it without root explorer by using the terminal emulator app with the VEGAn b5 rom (which is already rooted). The only tricky command you need to do is:
1. su
2. cd /
3. mount -w -o remount /dev/block/mtdblock3 /system
Step 3 is how you mount /system as read-write. That allows you to copy the apk to /system/app and to copy the lib to /system/lib. You can also copy build.prop to /system here. I also did the chmod commands here as well, i.e.
chmod 644 /system/lib/libSwypeCore.so
chmod 644 /system/app/Swype.apk
I had already edited the build.prop on another machine where I could use a real text editor.
This is the command to remount /system as read-only:
mount -r -o remount /dev/block/blockmtd3 /system
reboot and I'm Swype-ing away.
any chance you could paste the build prop edit in here? For some reason my browser is cutting off part of it.
Thanx,
I bet the mod deletes this within the hour!
Hmm, wonder how long this post will last
Agreed... I respect the effort tho and his directions are perfect!
Thanks brotha...
Sent from my SGH-T959
Instructions worked perfectly for me with the small substitution of adb push/pull to edit the build.prop (root explorer force closed after I had edited the file and before saving so I said screw it ). Thanks!
Combine this with the rainex fix for screen smoothness and it makes for a pretty good time lol
Sent from my Droid using XDA App
You don't have to adb it, that's why he recommended root explorer. If you edit it there it automatically makes a backup for you. I've done this with three ROMs, vegan4, zpad3, and vegan5... Never had to use adb

Swype Keyboard
Confirmed Working on the G tab following above steps. Stock TnT Firmware 3389. Working flawless. Sound and swype.
I am able to get the swype keyboard to come up and type on it but am not able to swype. Dont know what i am doing wrong.
Edited build.prop as shown in the forum still cant swype but just use swype keyboard as a regular keyboard.
Any help will be appreciated

Any downside to editing the build file in this manner?
Can you change it back after it is installed?
Do you have to redo this every time you go to update your rom?

Thats the nice thing about root explorer, it automatically makes a backup when you have modified it
Yes this would need to be redone for each rom.

I initially had the same issue, there's something incorrect in the build.prop. PM me and I'll get a copy of mine to you as i'm using VegaN5 as well.

Wow. I can't believe this is still here! Anyway, on to my question...
Is it possible/advised to edit the build.prop on a PC using a standard text editor like notepad? I ask because the browsers on my GTab don't show the whole of the text we're supposed to copy from tegratab.
Thanks in advance.
Editing on a pc is probably fine, however you have to make sure the formatting stays correct, otherwise it all goes south lol.
I printed out a copy of the top of the build.prop that rothnic posted on the tegratab site and used that for reference when editing on my tab....made it easier to see where I was in the text editor

Not that I have seen so far, and I've used this through two roms now
Can you change it back after it is installed?
as i2steve said, root explorer is awesome and makes a copy of the original file for you
Do you have to redo this every time you go to update your rom?

Unfortunatley, yes, so I would keep the files saved somewhere on your tab lol

need help with Root Explorer...

alright... I rooted my nook color, and I was wanting to change the screen specs to match the galaxy tab, but when I open my system > build.prop file in the root explorer, I can't change anything... any suggestions??
this is because the NookColor's stock LCD density is 169.333, which is pretty low (Galaxy Tab is 240). Unlike resolution, which is hardware-based, density is software-based and can be changed. If you search the market for LCD density, there are a couple apps that will do this--a free one that won't survive a hard reboot, and a paid one that (supposedly) will.
If you want to make it permanent for free, you can edit your build.prop file. Again, use Root Explorer to open system/build.prop (BACKUP FIRST!), find the following two lines:
ro.sf.lcd_density.xdpi=169.33333
ro.sf.lcd_density.ydpi=169.33333
If you wanted your density to be 250, you'd replace them with the following single line:
ro.sf.lcd_density=250
Save the edited file, and reboot.

Mount the /system partition as r/w first, there is a button on the top.
Forgot to mention that I tried that.. I restarted root explorer... no change

long press "build.prop" and select "open in text editor" from the popup menu.
Also 240 will be way to big. The menus wont fit. Im on 200 right now and some screens are off but not to bad.

Can't get /system into r/w
I'm trying to change my build.prop file to change the display density on my NC.
I have an edited file waiting to be used.
I want to rename the original build.prop to something like build.old and copy the new file in next to it.
But Root Explorer won't change /system to r/w.
I can't rename the original file or paste the new file.
I can flip root "/" back and forth from r/o to r/w without problem.
But nothing happens when I touch or hold the button when in /system.
?????????
Did you figure this out? I am having the same issue modifying files for the hulu fix.

u need to change the permissions to rw- r-- r-- before you reboot
Read - check all three
write - check the USER
execute - all are blank
save then reboot, then reboot (BE SURE TO MAKE A NANDROID BACKUP 1st!!!!)
Its not done that way.Even if the two build.props are edited and the permissions are set to rw-r-r sometimes you wont see a change.
This is because some custom roms now have a tweak to change the build.prop back to default on boot.So if you want to change the build.prop then you will have to change it in the computer and then reinstall the rom to your phone.

[Q] Built.prop Always restore to original

Sorry to ask this, but i was wondering why built.prop restored to it's original state when rebooting phone? i was going to edit built.prop to make some tweak...
But after reboot, built.prop look like untouched...
Using rootexplorer edit, Flash tool.

That problem I have but I searched theat build and find in system/bin/build and editet that and other in /system I don't know how is on Fd experience but on gingerxperia is
You have to edit both files in system/build.prop and system/bin/build.prop to make changes permanent.
And I think this applies on all ROMs.
Yes, must change /system/built.prop and /system/bin/built.prop to make a changes permanent for my rom it's /system/built.prop and /system/bin/built thanks

If you really need it now then do this :

Code:
persist.sys.usb.config=mass_storage,adb
then go to /system/etc/init.d and remove the S98MassStorage script.
Reboot and it should work fine.
If not , then you need to check rom customizer/. manage system apps / uninstalled tab and install anything kies, usb or mtp related
I have done the first part and removed - persist.sys.usb.config=mass_storage,adb but I can't change/delete/edit/move the S98MassStorage script, I have tried Root Browser Lite, ZArchiver and ES File Explorer.
Can somebody help me please, recommend a method/app?
Try "su -"
Then "rm whateverscript.sh"
To delete the file.
Assuming u got root perms.

Make sure your /system is mounted read-write. It should be, since you edited build.prop, but you can double-check (there's an option in ES File Explorer to mount /system as read-write).
