[Q] unlocking samsung captivate

I ran the bat file which I downloaded from here. When it runs it says can not find file nv_data.bin. Anyone have an idea what's going on here?
It is in the /efs folder. I am not familiar with the captivate, but do you have rw permission for that folder? Do you need root permission also? Do you have adb setup correctly? Have you tried to manually back it up with root explorer or any file explorer, then do whatever from the computer?

[Q] Issue editing build.prop

I recently rooted my Inspire and loaded CM7.2 RC1 and I was just trying to increase my download speeds by editing the build.prop file. I'm using explorer v1.1 to get to the system folder and then editing the build.prop file using the text editor. When in explorer it says r/w and I can actually edit the file and save it but it never seems to actually save the changes even though it says it did. I tried using mount/system(rw/ro) to ensure that it was actually mounted but I am getting the same result. Any suggestions would be appreciated!
ES file explorer
Hi, I use the es file explorer, when you open it up hit "menu" scroll to bottom and make sure both root settings boxes are checked, then restart app. You should be good to go.
I recommend ROM Toolbox. It has a root file explorer and many other tools which come in handy on a rooted phone.

[Q] xt862 att radio file push with explorer

Hello, newbie here, I have unlocked, rooted my droid 3 xt862. I have flashed the radio hack. I have one last issue that I can't figure out. How due I push the build file to the system file. I dont have root explorer just explorer from the android market. I clicked the file, hit copy, and tried to paste it in the system file. I wouldn't let me. I can't find the orginal file I flashed to my phone now, and if i could I wouldn't be able to figure it out.
1. do i need root explorer to accomplish this?
2. if not, where is the file on my phone?
3. How do I copy it to the system file so this phone will work with att mvno h2o wireless.
Please help!!! Im desperate. My email is [email protected] if you can help, or answer on this thread.
Thanks, Desperate Newbie
If you want to access the root of your phone use an file explorer like ES file explorer, be sure to enable root access in the menu, and you can then copy your file to the system folder
Good Luck!

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.
