S7 Edge - SW Rev Check Fail (BootLoader) Phone:8 Binary:7 - Samsung Galaxy S7 Edge Questions and Answers

Hi All,
i have a UAE version S7 Edge Duos model, used in Australia.
VOLTE option doesnt work and 3G signal is set to be shutdown in a couple of years.
850Mhz 3G band is already decommissioned. Only 2100Mhz band is operating now.
Hence i badly need VOLTE to work on the phone.
Current UAE firmware version 8 and all of Australian stock ROM's version is in 7.
Hence it fails to load via ODIN, complaining SW Rev Check fail.
Wondering if there is any way of applying a lower version (7) stock ROM firmware onto a phone with version 8 level.
Else, if flashing the phone to something like Lineage OS or anyother ROM would help?
Or Stock Sam fw ver 8 --> Lineage OS or others --> Stock AU fw ver 7 work?
Thanks

No method to flash a lower binary.
You need root and twrp. Flash latest alexndr's devbase in twrp.
Be sure to change csc to your operator whom you want to use volte with by reading instructions carefully in the thread.
Remember that it will trip knox. Good luck !

Do you believe everything you read here on XDA?
95% of all the users and developers here in this xda forum
have already updated the S7 and S7 Edge phones using
the latest Nougat 7 firmware version.
Good luck, have a great day!
I also have a Samsung Galaxy S7 edge duos (G935FD) and I did the update and my 3G/H/H+ data connection does not work when I have both SIM cards in the phone. I have to either use 2G or 4G/LTE for my data connection needs. 2G is too slow and 4G/LTE coverage is far and between in my area, I wish I could go back to Marshmallow.

You can go back to marshmallow firmware or roms.
If you are using the official stock nougat 7 firmware
you can simply go to http://www.sammobile.com and
download the latest Marshmallow 6.01 firmware and
flash it with odin in download mode.
If you are using a zip file custom nougat 7 rom you can
also go back to marshmallow 6.01 if you download and
twrp flash one of the marshmallow custom roms which
are available in this forum.
Good luck, have a great day!

Help with SM-N910H

Hi
I am noobish and would love some help from an expert
I Got my Note 4 SM-N910H on eBay a few years ago. I brought it unlocked not sure if its unlocked via IMEI or some other way (Its working with both USA AT&T sim and UK Virgin sim). Looks like it has been customized in some way because I went to Odin mode and it has binary & status custom and Knox voided.
Tried updating via settings and it will not allow it due to being modified. Tried Samsung Kies and it says its not supported.
Its currently on 4.4.4 firmware and i want to get it to 6.0.1.
I found a website with the official 6.0.1 firmware for N910H. (Cant post links but updato and samsung-firmware). The problem is there are multiple different country versions and I don't have a clue which country to pick? I want it in English. But there are none with USA or UK. Does the firmware country make a difference apart from language? I don't know what the original carrier was and there are no carrier specific apps installed. Does it have to be the same country as the original? Could I lose my unlock and not be able to use my sim card?
About Device:
Android 4.4.4
Baseband N910HXXU1ANIF
Kernal 3.10.9-2815469
Build Number KTU84P.N910HXXU1ANIF
Device Status Custom (Does that mean its rooted?)
I am happy with either official firmware or custom if its 6.0.1 or something better.
Please any tips/advice/guides or links would be greatly appreciated.
Thanks

4.4.4 is the best if you want my advice don't upgrade you will regret.
marshmallow and lollipop both sucks on note 4 and once you upgraded the bootloader will be locked and you cannot downgrade back to 4.4.4.
If your device status shows custom then it means it was rooted and modified for some reasons to make it fully work out of china because N910H is chinese note 4 3g model i believe.
just pick your own country. if its not available, just pick a neighbor country.
btw.....before you try any of those, try to boot to recovery and see if TWRP is installed. if yes, good, continue by creating backup of your current rom.
if not, I suggest installing TWRP first and make a full backup.
about kitkat vs marshmellow, I'll go with MM. With MM, you got more features, you got more recent android security patch.
yes, its worse on battery. but some tweaks here and there will (almost) fixed it.
Thanks for the help
Tried installing supersu and it says its not rooted so don't know why it says device status custom haha.
Yes 910H does say its an asian model but the firmwares are not asian areas they are more like african areas? The nearest one to USA is Trinidad and Tobago i think.
Think ill just stick with 4.4.4 since I don't know what I am doing
TY

Take your time to read on some threads. Just relax, no need to rush.
I have 910h myself, and I'm enjoying this device with root and xposed.
To root, get your cfautoroot. Its a simple process, just a few click here and there.
Custom status means that your knox is tripped. It means it has been successfully rooted before.
Trust me, its worth the time spent.

Galaxy s7 edge weird issue?

Hy all! This is my first thread.
And so sorry for my english.
So I bought a galaxy s7 edge (g935f) from the internet and it has a lot of weird issue...first this phone is a single sim t-mobile (hungary) version, but the software says this is a dual SIM version (935FD) I flashed a full-wipe 4 file from with Odin but after that the problem is still there. If I go to the ONE I menu the first imei is the phone's own imei, but the second imei is just a lot of zeros.
My second problem is that the wireless connections doesn't works.
The Bluetooth can't find any BT devices and the Wi-Fi is recognize only the 5ghz networks.(2.4ghz networks are invisible)
Is it possible to get this phone back to normal?
Is it should work if I try to reinstall the phone with smart switch? That app is download firmware that is match with the phone original carriers Rom.
Thanks in advance.
If the phone is the dual sim one (SM-G935FD) flashing the BTU ROM from SM-G935F (single SIM model) or the INU ROM from the SM-G935FD, it'll detect the second SIM slot that also works as microSD card.
By detecting it, it seems you have an G935FD...
try flashing one of those ROM's I have mentioned above with ODIN and do full wipe of the phone.
That will probably solve everything

Where did you get your phone from? Better return it...

G900F Rom Recommendation

Hi,
I have a G900F I got in the UK and I've just moved to Canada with. Problem is it doesn't support some of the bands here so I find I often have a poor signal. I'm happy with the stock ROM but I believe if I am to open it up for all bands I need a custom ROM.
I don't need anything too flashy, but I'd like everything to work and be responsive.
In terms of the most complete ROMs it seems LineageOS Official and Resurrection Remixed are the most popular. Can anyone comment? How about Android 6 vs 7?
Thanks
Used to use resurrection but now that I've moved to lineage os I can say that its better and getting improved every update it gets

g900f is almost identical if not the exact same as the canadian s5 g900w8.
you would need to use correct freq for your carrier, search will provide a howto. worse case scenario is to flash a canadian 6.0.1 modem from any canadian 6.0.1 stock fw
if trying to figure out connectivity, stay w/stock first as modems are from stock fw.
imo try superlite 6.0.1, it stock based and only takes a few minutes to install that way you can test out your carrier connectivity issues
https://forum.xda-developers.com/ga...-superlite-mini-mm-v1-0-361mb-g900w8-t3497158
So I can keep my stock firmware and just replace the G900F baseband (G900FXXS1CQAV) with the Bell Canada SM-G900W8 Modem and everything will be the same except the phone will work on the Bell Canada frequencies?
I had been planning to follow this guide: https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 to enable the 1700MHz band which is disabled on the G900F, but if flashing a Canadian modem will enable this band that sounds easiest.
Do I need to download the full 1.5GB firmware and extract the modem from it?
Thanks

ive never tried flashing a mdm from another model as ive never needed to for the s5.
ive not read enough to know if its possible or if it has any neg consequences.
easiest would be to change freq w/current mdm, search for samsung secret service codes to view and maybe change current freq
good place to start is here https://forum.xda-developers.com/showthread.php?t=2729694
I've done a lot of research on this forum. Most people say that installing G900W8 firmware on G900F isn't possible. Also it seems that it is the NVRAM which stores what bands are allowed on what model, so simply flashing a different modem won't make a difference.
Some people are saying that the hardware is different and this is what limits the bands, but I don't believe so, the radio/modem chip is the same version between models.
Trying to follow the link I posted earlier to change the NVRAM values after installing a custom ROM appears to be the only way. Some people say it works, and others say it only appears to work. The original thread was closed years ago so I guess I'll just need to try it and see.
Alternatively I could buy 2 phones, one W8 to use in Canada and a F to use in Europe, this seems silly though.

AT&T Baseband / Modem

I have gone back to my Exynos S7 Edge from my Snap unrooted ATT Note 8 .......
I'm trying the newer Oreo ROMs but it would appear that the newly flashed later baseband modem files pretty much suck for reception on ATT. Any suggestions for the best current ATT baseband that will work with the newer ROMs like Oreo ?
Also after having been gone for almost a year from the forum any suggestions for the best ROM experience currently ??
Thanks
