Please Help! just updated ROM and lost files

the "WM_(your name) My Documents" folder that I sync had these files in it and I didn't think that when updated the ROM it would erase those files yet all of my notes remain intact.
Can anyone direct me in the right direction to recover those files please? Any help would be much appreciated. Thanks

actually strange is what happened here in that it turns out the folder was copied, or recreated, so my old files are still in the old folder. so all is well. thanks anyway. tho if anyone wants to share any solutions for such a problem i'd be interested in knowing...

Phhhhewwwww! that was a close one

[Q] Is it spossible to chnge the system.ext2 file?

Hi,
I really like all the Android builds that use the Desire ROM as I really like the HTC Sense. However, my language isn't really supported there (The fonts exist but the formatting is bad).
I have some files that should fix the formatting, but they are meant for the original HTC Desire and are installed by going to the ROM Manager/Recovery Mode and then choosing an option called: "Install Zip from SD Card".
Since I can't go to this ROM Manager nor get into Recovery mode with the HD2 Builds I am looking for an alternate way to change the system files on the Android build I am using.
The thing is that I am having difficulties doing so.
At first I tried using EStrongs File Explorer to get root access and copy over the new files I want to change but it gave me an error that it failed.
After I couldn't make it work I started looking for ways to open and edit the system.ext2 file in Windows.
I couldn't find any program or driver that would let me change the files, but only view them so I decided to install Linux and do it from there.
I used VMware workstation to install Ubuntu on my system.
On Ubuntu I mounted the system.ext2 following the mentioned instructions here: http://forum.xda-developers.com/showpost.php?p=8001443&postcount=8
It mounted okay but it said there was 0 bytes free when I tried to overwrite the files I wanted to change.
In addition it gave me permission errors, the error was that I did not have permission to copy the files.
I am not that familiar with Linux and I tired googling for answers but couldn't find anything useful.
I would appreciate if anyone can explain how to do it, or direct me to somewhere with more details as I'm kinda stuck at the moment.
The files I wanna change are:
/framework/framework.jar
/app/.DS_Store
/app/Gallery3D.apk
/app/Mms.apk
And a few font files to /fonts
Thanks a lot!

It is best to mount the ext2 file as you suggest but instead of trying to modify the file, copy the contents into a new folder and use the genext2fs command to recreate the system.ext2 file!

Hey man, it worked perfectly.
Thanks a lot!!
By the way, is there a recommended file size for the system.ext2? Or should I just keep the original size?
Is it worth setting it bigger? Will it benefit somehow?

Cannot replace nv_data.bin

Hello all,
first to all who will say I must read the forum for problem solving - I did but from all the info out there it was simply too much. So I decided to start a thread in the hope that somebody will be able to help me.
So I have a corrupted nv_data.bin in my /efs folder but I still have backup of this file. But only this file.... I know - totaly dumb... I installed new JPX and after trying to change the product code from KOR to MOT (Slovenia) I accidentaly deleted nv_data.bin. I of course tried to replace it thru Astro Mate (I did had rooted phone - Darky's 6.0 was working fine ) but everytime I tried copiing this file tt didn't copy actualy - It said copied but the old file remained there - I know this because the Productcode didn't change. So I deleted the file thinking that this will help and tried to copy again. To my bad luck it didn't. I tried to copy and everytime a new file was created instead. also renaming a bakup file in this folder was not succesfule - it said Fald to rename file nv_data.bak. Since then my SIM card is not recognized and when I check what Baseband version I have it it written Unknown. So I tried even with ADB Shell, use busybox and when I eneter cp /sdcard/nv_data.bin /efs it says Now enough free space??? So I don't know anymore what to do. Does somebody have an idea what I can try to solve this? Please please please? I will donate to the one who helps me saving my SGS.
Thanks,
Borut

Hi !
This is because the file is used by the system.
Safest method:
- Reboot into recovery (make sure you have root in recovery)
- do what do need to do in recovery
- Reboot in normal state
In recovery phone / baseband / RIL are not started.

so you mean when I boot in recovery i can copy the file using adb shell? Or how do you mean I can do what I must do?

I have done it before while the phone is on, but you have to enter flight mode, set the correct owner and rights and reboot afterwards.

Well, regarding ownership and stuff like that - I'm a tootal noob

Help please NV_Data.BIN
I know this isn't the place to post this but I have been trying since yesterday afternoon can't figure out where I should post it to I keep getting an error that due to spam I can't post to certain areas without having 10 posts.
Please help -
I am not sure what to do now. I changed the rom on my phone to put 2.2 on it a while back. I never saved any of the files because I was not aware to. Now I am trying to go back to stock already used the one click Odin program and I have the original stock firmware on it. But when I try to update via kies mini it will not show up. I have searched And found multiple postings related to the fact that the product id and imei could be incorrect and you would need the original nv_data.bin file. I have searched through windows explorer on the phone but can't seem to locate one. Is there any way that I can get a copy of the original folder for /efs/nv_data.bin and any other files that are needed?
I have the Samsung Captivate on AT&T currently running 2.1
BaseBand: I897UCJF6
Kernel Version: 2.6.29 [email protected] #2
Build number: ECLAIR

You need to check your IMEI matches your original .
You have stock rom stock as in not the network supplied firmware that came with the phone ..
Windows explore is no good you need something like root explorer .#
I can get a copy of the original folder for /efs/nv_data.bin and any other files that are needed? Not unless you saved them they are phone specific .
Worth doing a factory reset before you make any step as that may solve your problem .

how do I check the original imei? I didn't backup the files as I was not advised to in the information I found online at the time (couple months back). I have done a factory reset via the phone (privacy settings) a couple times now and still when I plug into kies it tells me Unregistered device.

This is very simple to fix if you have nv_data.bak in the EFS folder.
If that file is present then you can safely delete nv_data.bin and reboot the phone.
A new nv_data.bin will be generated.

how do i know if I have nv_data.bak? where on the phone would I find it and how?

Click to expand...
Click to collapse
It should be in the efs folder (unless you've done something to delete it). As said by JJEgan, you will need root explorer. Navigate to it in the efs folder and copy it to the external sd card and then keep it safe somewhere.

how do I check the original imei?
Its on the box and or with the receipt .

build.prop

Hi, I'm wondering if anyone would be so nice to upload a backup of the original, unchanged build.prop for the a500 tablet... I've made a few changes to mine but failed to backup the original. Any help would be greatly appreciated. Thanks in advance.

thank you so much for the file!

location?
where is the location of the build.prop file on the system? I need to replace mine with the orig so i can update. but dont know where it goes.

/system/build.prop
if you dont know where it is.. it probably isnt changed as you would have changed it yourself, the netflix hacked apps dont

how to edit
I have mounted my system dir as r/w and I am unable to rename the build.prop file. I found the orignal backup in the same place as build.prop.backup. I just want to rename them temporarily so I can get the OS update just released. How do I rename the files. I have ES File Explorer installed. and system dir mounted as r/w.

Can anyone walk through a newbie to this on how to change the build.prop to let the market know I am not on an Acer A500 but a Samsung Galaxy S or other device that is supported on the App I am trying to download? (already paid for and working on my droid inc).
Thanks.

Can someone do me a favor!

Please I really need someone with root and didn't deleted some files do this for me!
If you are not sure you are the person, do it anyway, maybe it can be useful!
Ok. Run the file attached (remember to unzip first) and see if there is 2 files on the folder (after you ran it!), the files are "recovery-from-boot.p" and "install-recovery.sh". If you found those files, please upload them to me, as I download it I give you thanks and mention you on my Thread LordAIOTool, I need the files to use on it!
Thanks

I'm not on Windows, but looking at your batch file, it looks like all you're doing is pulling /system/etc/install-recovery.sh and /system/recovery-from-boot.p, yes?
If that's the case, here's those two files from my MZ604.

Ok, thanks

FYI recovery-from-boot.p only works for a specific boot images (namely the stock one that is shipped from google).
If you try to use this file on any other boot image it will fail.

Keep up the good work, looking forward to your #10 AIO Tool! Hope you fixed the Mount SD card issue.
