Hi Kenzo888, Upon searching I do not have the .nv file or the or the md5 file either. All I see is the nv_data.bin file in the /efs/root folder and one /efs folder.

I am not sure if the others have the same but I have the same exact IMEI shown in the OP (1st post by amanvir).

Hope someone can help.

I only have two nv files (nv_dat.din and nv_data.binrm) from that directory. I read from the other forum threads that using nspro for unlocking screwed their IMEI as well showing the same IMEI from the first post. gosh!!!

U sure that ur files is nv_dat.din and nv_data.binrm ?

I had this problem and it is because the app is supposed to take the nvdata.bin out change the codeing to make the phone unlocked and then it puts the file back in the phone and your unlocked. If it is not there then the app failed to restore the .bin and thats why u have no imei. Find the file and push it back with the adb method for unlock. I do not like these unlocking apps. they can cause too much bs if they do not operate properly. I use adb to extract the file to my sd card and then place on desktop and edit the file with a hex editor. U only have to change a few 0's to 1's or vice versa and its super easy if u follow the thread about how to unlock the sgs 4g with this method. (can't remember which one but it is in our forum for sure) Then u push your nvdata.bin back to the phone with adb and ur unlocked. To relock the phone u do the same method and change back what u changed to unlock it. ( 0's to 1's or vice versa. just read the thread.)

I'm kind of in the same boat.
I bought a phone off craigslist didn't work now im stuck with a phone i can use wireless on. attempting to make a call, the call drops instantly , received calls go straight to voicemail.

after researching all this past week.. i've noticed the following probles so here is my situation at hand.

i have the IMEI issue with corrupted characters except mine says 04 at the end.

unable to root.

unable to put this phone in download mode
(attempting to fix the imei issue reflashing with odin)


I have no back up files

unable to enter recovery mode manually. I read from another thread someone was able to do so using t mobile one click root program for vibrant ,
which works for this, but when i tried to root i get e signature verification fail issue as well.

I've read countless threads and forums and about to inquire to samsung or t-mobile for a repair. my aim is to get this phone operable.

i'd like to help myself on the issues but find myself at a dead end with being unable to put in download mode ,and yes ive tried the different methods of holding buttons/ inserting usb.

and at another dead end being unable to get this rooted because of signature verification fails.. any help or direction would be greatly appreciated.

are the files device specific? cuz if not i had same problem and i fixed it...i will post file if not device specific, someone just let me know.
