G920F no wifi after ODIN update 5.1.1 -> 7.0 stock

Hi
my G920F was 5.1.1 but OTA update after download 1.8gb of new firmware didn't finish update.
wifi work OK in 5.1.1
i used odin 3.12.3 and FIRMWARE XEO: G920FXXU5EQD7_G920FXEO5EQD1_G920FXXU5EQCD_HOME.tar.md5 after this phone powerON normally but can't enable wifi, it stuck on "enabling..." info but don't switchOFF just ...enabling..... and nothing more. Is switch off after 2minutes not faster like i saw on youtube videos.
i tried to use OTA but then phone said this update was made by: "unauthorized..bla bla... and USE: Smart Switch to download correct firmware"
i used smart swich tool which again download 7.0 firmware and upload it with ERASE option but nothing change still WiFi can't be enabled but bluetooth, network both work ok
wipe via recovery also done
now firmware flashed by smart switch is:
AP: G920FXXU5EQD7
CP: G920FXXU5EQCD
CSC: G920FXEO5EQD1
maybe i should use another firmware via odin with different modem?

Make times before a full wipe.
If that does not help, then load a 4tlg firmware with SamFirm down, which you also then with Odin flasht.
Example Picture:

Thanks for reply. I will test it but also could you give me a link to this samfirm tool which you used on screen shoot?

You had right, today (I left phone alone for weekend) I made hard reset again (via recovery) and wifi starts to work again. This is very strange I've never face such thing before.

Unsuccessful Unrooting of AT&T G930A using Kies or Samsung Switch

Hi all,
I successfully rooted my S7 from Nougat using the guide below:
https://forum.xda-developers.com/tmobile-s7-edge/how-to/heres-how-rooted-nougat-s7-edge-g935t-t3567502
But performance seems to be suffering since then. I'd like to unroot back to stock, but:
1. Can't find a stock firmware image of G930A to use with Odin
2. The newest version of Samsung Switch no longer has the "Device Initialization" tab as shown in the guide here:
https://www.youtube.com/watch?v=9QhJngOuLQ4
3. I've tried with Samsung Kies as well, which seems to not properly recognize my device serial number.
Has anyone had success in finding an older version of Switch or other methods of unrooting the G930A?

Hi, same problem. Did you ever solve this? Thanks!

You checked both sammobile.com and updato.com?
If so try G930U firmware since it's just the unbranded firmware for US phones, works on all of them.

I did actually solve this a few days ago to unroot my Galaxy S7 G930A.
I used:
Odin V3.12.3 Patched
G930U Firmware (AP, BL, CP, and CSC files) from Updato (https://updato.com/firmware-archive-select-model?record=9CDE46F3EB8211E7A5F9FA163EE8F90B)
After doing this it honestly feels like I have a brand new phone. Huge performance jump compared to the rooted package.

Kindly Help ... no updates are received for my G930FD !!

Hello,
I have the G930FD version of S7 (the dual sim version).
I am on the official samsung Firmware but I don't receive OTA updates. Even when I connect to Samsung Kies it also shows there are no updates. last update was security update for April 2017 !!
Please help me.

Who's your carrier and where are you located?
Otherwise flashing the last firmware with Odin and using home_csc will update you without data loss.

I use the unlocked version of the mobile which I bought from Saudi Arabia. how can I use home_csc since I am a bit noob in these things

https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin
Boot into download mode (VOL DOWN + HOME + POWER until screen goes light blue) to confirm your model number, download the firmware for that model, and put the files into their slots in Odin (i.e. the files called BL_G930FXXX goes into the 'BL' slot etc, but for CSC put use Home_CSC and not normal CSC.

Going back to SM-G955W from SM-G955U

Hi i bought a second hand s8+(SM-G955U) it was still on nougat and i didn't get any OTAs, so i update it to Oreo with Odin. I still dont get OTAs, and i never could find my CSC related firmware in g955u models on sammobile. so i looked up my device in IMEI.info and find there that my device is actually G955W and from there i also found my CSC based firmware in Canada my CSC is XAC. I just also find on the back cover of my phone that my s8+ is actually SM-G955W. so my question here is how could i go back to g955w firmware? Just download g955w firmware and flash it through odin?
In setting my phone is
SM-G955U
Baseband version G955USQU5CRL2
Service provider SW ver.
XAA/XAA/XAC
and the firmware ive downloaded from SamFirm is
Model Sm-G955W
Region XAC
PDA G955WVLU5BRJ2
CSC G955WOYA5BRJ2

Use the patched version of Odin. Just search Google for "patched Odin" & you'll find it. However, if you use the G955W version of the firmware, you'll lose several features of your phone. For example, the G955W firmware disables the FM Radio. Good luck.

Thank you so much friend, i will sure try it and let you know.
You know i don't really use radio and the main reason to switch is because i don't get OTA updates, anti malware in device Maintenance's won't activate, and i couldn't install certain samsung apps like samsung members and samsung+
Thanks again
