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?

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 .

Atrix Custom Backup For Each Sbfs

Hi,
I readed this
http://forum.xda-developers.com/showthread.php?t=1041572
then I had an idea that is just simple
I got tired with my att atrix for many months now we can't flash any sbf on that phone.
I suggest that people dump data and system files and all other folders for all the sbfs that are shared.
that is as simple as it is, after that we just need to update the folders and files over the old ones.
I will also try myself to extract contents inside the .smg files of sbfs using linux but I can not garantee it will work since I don't know what is the real file format of current atix smgs right now.
I will create a shell script that will do the job easily and I need people that have Bell atrix, Europe Atrix, Latin atrix or Asia Atrix.
If we succesfully overwritte those folders and files on our phones, I'm pretty sure that future update will also work since update.zip is just looking for right files on the phones and not checking for 1init bootloader version.
Who would like to participate and try?
for those who have questions, feel free to ask me

extract sbf
rename CG57.smg to system.img
use kitchen to make a update zip
or
make a nandroid backup
use system.img from clockwork/backup folder
use in kitchen to create update.zip

Hi Odia,
I can provide you with an nv_data.bin file or even the content of the whole EFS folder. I also have a question on this - I heard and see that you are The Expert here on these kind of stuff. The stuff I can send you does not contain my EMEI only a generic but otherwise seems to be OK. Let me know how would you like to receive the files. Also I have to state that - although it would of course be welcome - your help is not "in exchange" for mine.
So here's what happened:
1.) I was using various custom ROMs (rooted of course)
2.) Went back to leaked stock ROM (here comes the problem) 4.0.4 LPQ5. Unfortunately I learnt only after installing the ROM that its PIT file is corrupted. Error messages begun to show about "internal storage not formatted", etc. probably here I made the second mistake agreeing to format the storage. After that I had generic IMEI, had CSC, HW_rev. and Unique number unknown and a black semi transparent window stuck to every screen showing that.
3.) Re-flashed (with Odin) an older Samsung stock 4.0.3 FW (actually the one I bought my phone with), now everything seems to be solved except the IMEI which is still generic 004999010640000. At this stage I took a backup of my whole EFS folder I can provide you with. (Yes I know, I should have taken a backup of EFS before I started to even touch the ROM)
I learnt that the nv_data.bin contains the IMEI in an encrypted form so restoring the original IMEI it's not a simple hex editing. And that's where I'm stuck at now and would welcome any help.
Best regards and please have my appreciation on your work and contribution here!

Hi,
You can try with Philz Recovery instead of CWMRecovery.
You can also try to open your backup file on PC to see if there is some files inside

HTC Desire 820s

Is that phone totally abandoned by htc ? i just baught it 2 days ago
if saw i would replace it with other phone
can any one just answer it simply

I think the lollipop firmware is here
http://ir-file.com/portal/index.php?dir=Firmware/HTC/HTC_Android/A50ML_DTUL/
We shouldn't expect any lollipop firmware unless maybe we flash it.
My phone had lollipop out of the box but I flashed kitkat so that I could root it and modify it, but I found it to be too boring, I'm looking to revert to lollipop

Yes I can delete them. I tried contacting them, they said it's an encrypted zip file couldn't be extracted. Don't know how it's going to be flashed

Here

Extracted

can you provide me the download link directly , i don't have to make an account ,,,,, whatever it is i will start porting sense 7 form desire820 lolipop , i will see if i can
but i need to make sure that htc has forgot about us

Deleted

So when I repaired the zip file with winrar, I was able to recover these files.
Scatter file shows HTC_A50ML which is the D820ys, it comes with Lollipop out of the box.
This zip file is encrypted, only if one could find a password to crack it, or if someone has the knowhow to extract this kind of files

d820ts
is this update available for d820ts???
