Hello everyone,
I need help with resurrecting the above phone model. After updating it via Samsung Switch, it 'magically' stopped receiving network recognition but it could sense the SIM card's network operator. I tried dialing some numbers and it said "Not registered on the network". I ran to the internet through various forums. I have been re-flashing STOCK ROM and i was getting PASS; still no good came out. I tried custom ROMs, same thing. NOW suddenly i got an efs/ failed to mount. How can i resurrect my baby? All i have about the phone is:
AP: G925FXXU6EVG4 (Build number) - NDR90M
CP: G925FXXU6ERF5 (Baseband version)
CSC: G925FXXU6EVG4 (Country version) - 02U
IMEI SV - 02
SN - RF8G610C1MN
The stock ROMs i have downloaded so far are:
1. Samfw.com_SM-G925F_O2U_G925FXXU6EVG4_fac.zip (stock ROM based on the last successful booting ROM; after updating via Samsung Switch)
2. Samfw.com_SM-G925F_O2U_G925FXXU6ERG1.zip
I have these in place:
- Samsung S6 Series EFS Backup Restore Tool v1.0 By Jamesjerss.exe (which i used prior; to get an efs.img before my phone got messed up (a 20Mb file was created). Is that the backed up EFS?
- Odin Odin3_v3.14.4
- CF-Auto-Root-zerolte-zeroltexx-smg925f.zip
- twrp-3.3.1-0-zerolte.img.tar and twrp-3.3.1-0-zerolte.img (i wonder the difference although the internet says i use .tar with Odin)
- SR5-SuperSU-v2.82-SR5-20171001224502.zip
Now, the stock ROM stops on the RECOVERY MODE with efs/ failed to mount, and when i try the custom ROM, it stops on SAMSUNG Galaxy S6 Edge. In all recovery modes, good enough my PC detects my phone's internal storage. I need to get this device to work, people.
Someone help with with a step by step tutorial, please. I am a fast learner
PS Am not a tech student or anything, am just a person who reads stuff on the internet although i understand some basic stuff on tech

1. If you think about Smart Switch Mobile, it is not for update.
2. Go back to Stock firmware via odin.
2. Have you seen >this< tutorial?
how can i know the stock firmware of the phone....i only remember the one that was updated via Smart Switch (Hanset: Samsung Galaxy S6 Edge G925F single SIM card slot no SD card slot)
1. Check your CSC on the phone box or with the Phone INFO app ★SAM★ 3.8.5.
2. Select your CSC region in the "Version" box read the instructions and download the firmware.
3. Use Odin 3.13.1 to update this model.
@ze7zez. Just bought it from some phone shop that sells used phones. I have the needed STOCK firmware already. The CSC is 02U G925F---VG4. All am getting is this image below:
Since your system is not working, go to "View recovery logs" and look for CSC or "region name".
You can also try uploading firmware from your country's region.
The CSC is 02U (O2) which according to internet research it is UK

I already have all firmwares for this handset from 02U. I have tried EVERY STOCK ROM...but all am getting is E: Failed to mount '/efs' (Invalid argument).
I tried EFS-Fix-regalstreak.tar.md5 basing on https://ajketech.wordpress.com/2016/07/27/efs-missing-factory-mode-activated-here-is-the-solution/ i got FAIL.
I do have an efs.img i made before all of this whole saga but i don't know if it is broken or okay.
Try flashing TWRP from >this< manual. Read it carefully!
With TWRP you will have more options for repair.

You may need to flash a Three modem
Read this: [REF] Galaxy S3 Modem / Radio Collection (I9300 & I9300T ONLY) CWM & Odin Flashable
To flash a new modem:
1. Download an official rom from http://www.sammobile.com/firmwares/ and extract the zip to md5 then extract the md5
2. In Odin, select “CP”(previously “Phone”) and fetch the modem.bin file
3. Only thing checked should be “Auto Reboot”
4. Put the phone in download mode, plug in USB, then in Odin hit Start
Hey Guys,
I've come across my limit of knowledge during the past days.
I purchased this new phone, "Samsung Galaxy S 7".
When I look up the "About phone" option in "Settings", it says, that it's a SM-G930F with android verison 6.0.1.
I couldnt find ANYTHING according to my Build number, which says: MMB29M.G930FXXU1BPIA or that my Smart Switch says, that the software version would be PIA(VZW).
But when I go into Download/Odin-Mode there are the following text lines:
ODIN MODE (HIGH-SPEED)
PRODUCT NAME: SM-G930V
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: OFFICIAL
FAP LOCK: OFF
QUALCOMM SECUREBOOT: ENABLE
RP SWREV: B4(2,1,1,1,1) K1 S3
SECURE DOWNLOAD: ENABLE
So, both informations are dividing from each other, because the first says it's a SM-G930F and the second says it's a SM-G930V, except that both have in common, that they say system status is official.
But, my problem is, as you can see, it's still marshmallow that is installed on my Galaxy S 7 and in my settings there is absolutely no possibility to update my phone to nougat.
I've tried several things via Odin like installing: Stock firmware for ADB, Nougat firmware for ADB, Stock firmware for VZW, Nougat firmware for VZW
But just nothing worked out.
Most common issues I had with Odin were: "sboot.bin FAIL!, recovery.img FAIL!, Complete(Write) operation failed.", depending on what kind of files I tried to apply, like pit file, AP-File, Home_CSC-File, etc...
Even if i tried to solve it with the most common troubleshoting methods i could find on google, there would be another issue, like a never ending story.
I also tried applying a firmware with recovery mode but there it says: E: "footer is wrong” ,followed by “E: signature verification failed", even if my SD-Card has never been encrypted.
I dont have any idea what to do anymore,
so i would extremely appreciate some help of a pro, who can tell me, what to do exactly.
Thank you!
*EDIT*
I managed to unroot the phone with the verzon nougat firmware but now it won't let me use the phone with a diferent SIM-card than a Verizon's and I'm going to return the phone.
Hi,
I'm facing the exact same problem.
Which Verizon firmware did you use to unroot your phone?
Thanks!

I managed to flash the latest Verizon ROM (SM-G930V_1_20170330100826_87cd9631jd_fac). Now it is obviously branded and I always get a message (after reboot/after ending airplane mode, so everytime the phone connects to a cellular network) that I'm using a non-verizon sim card. Nevertheless, after manually adding the APN, everything works fine, no SIM lock.
Edit: it works even better with this stock ROM w/o branding: updato.com/firmware-archive-select-model?record=EF06A1ED34EB11E7963AFA163EE8F90B
Same Problem

but when i go into download mode it shows 930v
cant update my phone it's still stuck in ****ty marshmallow
i would highly appreciate any sort of help.. TIA

you have the exact same issue as me. I suggest you review this thread, it would be helpful.
In summation, you have a converted phone. you can flash Verizon's rom if you want nougat. But that didn't help with my network issues.
Same problem
is this phone is not official what's the matter please explain
I'm also having the OP's exact same problem? I thought the phone I had just bought off gumtree was fake. I'm in Australia and noted that the model one the sticker on the back on my device is SM-G930F, the "about" page lists it as SM-G930F running 6.0.1, odin lists the as model SM-G930V, smart switch as PIA(VZW), CPU-Z as having it having a Snapdragon processor and finally the paper instruction manual is for a SM-9300 (China) - WTH!?
I cant seem to figure out which device it was or is ha! I believe it may be a chinese device that has been flashed to american standard. Is the the core point here, are these perhaps all flashed/refurbed chinese models?
Long story short, i'm not having any problems but i want a newer OS like oreo or nougat - if I flash to say SM-G930U standard with XAA (generic, samsung branding), will i begin having network issues in Australia?
I bought A used S7 edge, I have issues with 4G use on my phone, and It wont update past android version 6.
When I used SAMSUNG INFO app I found the following:
Bootloader Version: G935VVRU4API3
PDA Version :G935FXXU1BPL2
CSC Version :G935FXXU1BPL2
Baseband Version :G935VVRU4API3
CSC COUNTRY : HONG KONG
SAMSUNG SERIAL NUMBER : 00000000000
I have 4g connectivity issues especially on whats app (can only send text but can't send media), Facebook ( works for a while and then 4g stops working on it) , yahoo mail (won't refresh or open/send emails unless on wifi) , and linkden ( feed doesn't load unless on wifi), and youtube works with no issues.
This issue is killing me, how can I fix it? I live in the middle east (Jordan), does that effect anything ? I already factory reset my phone and re-installed all my programs, I got my SIM Card checked, I checked with my service provider and nothing is wrong.
Help! what can I do to fix my problem ?

Can you notice that it says on phone info its SM-935F but in download mode it says its Sm-935V
Hi , your SN must to show up , also when you are dial *#06# , to make sure what is correct firmware you should see on the Battery cover glass to the bottom like for example :
SM-G935V ( see if is V , F or some other )
Made in Vietnam by Samsung
S/N RFxxxxxx
IMEI: 357090/07/3957276 ( compare your imei with imei which is written on the battery cover ....
Once you find real model name go to updato.com , put your device model and download latest firmware for your region.
You can use IDM for fast downloading , also you need Odin . you have over the internet how to use Odin and how to flash ....
But , before you are doing anything back up your data , also remove your google account and samsung account from your device , make sure your battery is full , do Wipe Cache Partition from Recovery and do Factory Reset . Then flash latest firmware with Odin .
Good Luck

Well the battery cover (Back cover) has been replaced with another one so I can't get anything off it, on the download mode it says its a G935V, but the software installed on it is G935F as you can see from my (Settings- About phone ) screen shot....
I don't think If I flash the G935V firmware it'll work because I am not in the USA and There is no Verizon here, I live In Jordan (middle east)
Can I flash the G935U software? will that solve my whole issue? do I flash the whole thing ?
anyone could help out ?
Your phone is for sure somehow "modded" device registred on database with your imei is registred as G935P made for USA not G935F or G935V . Who knows what the owner before you has done with him or somebody else .
So my suggestion is to flash firmware for G935P
https://updato.com/firmware-archive-select-model?q=G935P&exact=1&r=&v=&rpp=15
Choose region USA (Sprint) SPR or XAS use latest Android 8 with latest Odin version or try last Android 7 .
So I have a rooted Galaxy J7 pro with me (SM-J730f/DS)
This phone was rooted and it was blocked at boot showing "Custom Binary Blocked by OEM Lock"
I went into Odin mode and there wasn't anything that showed a country code. So I downloaded a stock rom according to my country and it's carrier was open (which I thought meant any carrier, I mean there ain't any career named "open" in my country) So I flashed it using odin, everything went smooth. The phone is performing well but after inserting sim cards, it detects the sim but doesn't work. Shows "unable to connect" and "error while connecting" when I tried to set network manually.
I probably should now flash the correct firmware but I don't know in which country this phone belongs. I dialed *#1234#* but I obviously got the information about the rom I installed.
In the back of the phone "UK" is written after the model number (SM-J730F/DD, Samsung, Yateley, GU46 6GG, UK) but I couldn't find a UK rom. I looked into Imei.info but couldn't find any info about region.
Is there anyway to fix the issue other than trying every J7 firmware there is
Hey I just my Samsung galaxy s20 (SCG-01) is locked to the au network in japan (Blacklisted too I bought it second hand ), and I tried many ways to unlock it but nothing helped, So now i'm trying to install a different region firmware same model same specs the only difference is the region. My model - SCG01, The firmware I'm trying to install - SM-G981U. But when I try to install the firmware through Odin, it shows a message as a failed in red. When I click start in odin it takes around 3 seconds and the failed message is shown. My problem is why can't I install a different region firmware even thought all of the other specs are exactly same in my device, Please help. I'm using the latest version of odin as well
