Help for S5 G900FD NV 6828 and 6929 original values
Hi, I need your help.
I have a Samsung S5 Duos G900FD.
I flash the stock rom of S5 Duos G900MD and root for add all LTE bands in thread for this web.
I modified Only NV values 6828 and 6829 Without backup.
I need the original values for NV 6828 and 6929 for revert to fact my model S5 G900FD.
The problem is no connect 4g in 2nd sim and vice versa.
I factory reset s5, reflash rom stock but problem persist. I see values with QXDM for NV 6828 and 6829 in decimal is 17592186044415: that supposedly activate all LTE band. Only work QXDM software in my S5 G900FD, other soft that EFS profesional only read values and not write it.
I want to come back from the factory original S5 or revert the problem.
Please send me to backup NV values for 6828 and 6929 for S5 G900FD.
How I said, simple flash to stok rom don´t solve the problem.
Thanks I wait your answers.

It's in the efs folder, but if you didn't made backup I don't know how to restore it, maybe in some samsung repair service with Z3 box???
If you didn't back up the efs folder.
You are DONE for. End of story.
If there's a CM7 port for Galaxy 3, you can use that to provide a temporary IMEI, but once you flash back to stock firmware the imei will disappear again.
Hello,
I am Ankit from INDIA.To cut the long story short i just flashed my Galaxy S3 to come back to official 4.1.2. (was running on leaked 4.2.2). after flashing the device i rooted it with CMW to reset flash counter and then flashed again to official 4.1.2.After Flashing the device screen appears No service & IMEI changed to 0049.....
Then i downloaded new firmware from sammobile.com.Now got everything back IMEI is correct have network but am unable to get HSDPA network.phone is working well in GSM Mode but as soon as i chooses HSDPA gets same problem of No Service.
I have tried all the things like EFS backup restore,CSC update etc...But getting network onlyon GSM Mode(Tried with 3 different Sim Cards).

I have a Samsung Galaxy s4 e300s 4.4.2. I Flashed I9500 Galaxy S4 OzcanRom v6.3 Aroma XXUGNJ1 KitKat 4.4.2. Then after flashing the rom, the signal lost. IMEI becomes null/null.
I tried :
Restoring CWM Backed up that i backed up before flashing the Custom Rom[ I9500 Galaxy S4 OzcanRom v6.3 Aroma XXUGNJ1 KitKat 4.4.2]
Flashing back the Original Firmware using odin.
Doing the EFS Professional Backup/Restore method.
ES File Explorer's efs folder where you need to back up the "efs folder", deleting stuffs like nv_data. (But i don't have ".nv_data.bin". maybe that is why i didn't successfully done it.)
Flashing the "S4-GT-i9500-Fix_imei_null.tar" (I read this method on forum.gsmhosting.com)
i also tried downgrading it to 4.3.
All of them didn't help me.
Earlier today, i went to phone technician. They successfully got back the Signal. But not the IMEI. It is still 0000/01. I wonder how they did that, if this is safe and if it is just okay. If anyone here experts/professionals who can help me bring back my IMEI number.
Thankyou in advance

Hello and thanks for checking this post!
Ive bought a LG G3 D850 in USA, unlocked. When moved to Argentina I was not able to get 3g/4g signal from my local carrier, only EDGE, as the phone wasnt sold by them they rejected to assist so on my own Ive made the following steps:
Hidden menu fixes - didnt work
Edit build.prop - didnt work
Updated from stock 4.2.2 to Fulmics 5.2 - didnt work
Flashed new .qcn files worked as follows:
.qcn #1: I was able to improve quality signal for voice and data, also fixed 3g and H connections.
.qcn #2: Quality signal decrease, EDGE works, no 3g and no H but 4G works.
What I would like to know:
1- Is it possible to use the .qcn #1 and restore my factory IMEI so I can at least have H?
2- Is it possible to edit the .qcn#1 and include the code portion from .qcn#2 that enables 4g?
That would be the perfect fix for this issue!
ps: Ive the original box with the IMEI labels and also the internal label that confirm phone original IMEI, I know change IMEI is not legal and its not what Im trying to do, Im looking for a fix keeping my IMEI stock.
Thanks for any input!
