Hello amazing XDA devs,
I need a bit of advise and help with flashing oreo firmware on my device. I have already done a lot of research already but have failed to find any satisfactory answer. So here is my story,
I purchased my galaxy s8+ from korea. Model number is G955N. I wasn't able to get volte signal on it hence, rooted it and changed the csc to India.
In the process I also had to update my BL to AQL3.
I am now trying to flash an indian firmware on my korean device. i.e. installing SM-G955FD firmware on SM-G955N device. I undestand hardware of both the devices (korean and indian) are same. So, there should not be any problem in this cross flashing of firmware. However, ODIN doesn't allow this.
Here are my few queries which I hope you can help me with
1) Would it allow me to flash *FD firmware on *N device if I use prince comsy odin or some other custom odin?
2) Do I need to flash *N oreo BL if I decide to flash any other custom oreo rom which supports F/FD/N variants?
3) Where can I find *N oreo BL and AP to flash if only option is to install custom oreo rom?
4) If I flash oreo firmware for *N variant, would I loose my csc changes and I will have to start all process again to get back volte signal?
I know this is a long list of question. But, I am sure a lot of people have these queries and it will help all of them in understanding the process and upgrade their devices if these questions can be answered.
Would appreciate your help on this matter.
Thanks,
I got it..just flashed the oreo rom from twrp and everything seems to be working fine.
hello. which custom did you flash ? also need it. thanks
I have my G955N made 2 sims aleady.
I observed that the developer did the following steps:
1. They made it support 2 sims: IMEI guru software
2. They flashed custom that supported G955X:Renovate ICE in xda
3. They changed 1 slot sim tray with 2 slot sim trays.
4. I observed that BL and CP are of G955N but AP and CSC are else from G955X.
Thanks?.

As 3 UK now support VoLTE I want to flash the latest VoLTE 3 branded firmware to my unbranded phone but not sure how to go about it.
Is it just as simple as flashing the 3 firmware or is it a bit more complicated? I've heard stuff about pit files and not being able to sign them so not been able to flash carrier specific stuff to phone.
Anyone successfully done this?
Hi All,
I have a moderate experience in flashing firmwares and modding my samsung devices over the years.
I have recently purchased an S7 which is unfortunately a SM-G930V model, i thought it would have been the SM0G930F which would have made life much easier.
I want to know if it is possible to get the original Australian firmware or even generic stock firmware on this device?
My issue is with the network settings where i have manually put in APN settings my match my carrier and 4G coverage in australia.
If not am i able to just flash a different baseband to this device preferably Australian?
I have read that flashing a different model firmware will soft brick the device, i just want some insight before i start breaking things, also what are my options.
Much appreciated, thanks, Will
You have the snapdragon s7, you can't flash the exynos 930f firmware on it, you can only flash the american firmware. You might have luck with the 930u unbranded firmware just do some research on it.
Thanks mate,
I'm going to flash this firmware using ODIN, do you know if it will be successful?
https://forum.xda-developers.com/att-galaxy-s7/how-to/xda-community-love-g930u-t3415875
not sure how to check my bootloader version etc
No clue, goto the verizon subforum and see if anyone flashed the 930u firmware on their 930v.
Just tried to flash the firmware to my phone and recieved an error, the phone is now stuck at download mode with error:
sw rev check fail : [system] fused 3 > binary 4
this means the bootloader won't accept the firmware?
LOL, guess ill try another firmware.. Any ideas?
Hi all,
I am a new owner of galaxy S8 plus.. My phone has the following CSC G955FOWA1AQDD .. My question to you all is what are the possibilities of flashing and custom roms that i have in specific
1. Can i flash an official firmware that is different from the current one that i have i.e. more recent / different country? if yes, what are the firmware options that i have and a newbie step by step instruction or guide would be appreciated
2. What custom rom options do i have, is it dependent on csc number e.g. G955F or the group i.e. OWA as i haven't actually seen a device that is G955FOWA its either OXM or G950FOWA ..
Your help is appreciated for this new owner, and any advice you have!

Yes you can flash firmware from other countries as long as the device model is the same.
Im not going to post up a guide as they are everywhere juwt search here or Google "how to flash firmware with odin" it is very easy to do.
Make sure you backup as sometimes it willbe required to factory reset after a flash. Also flashing any csc other than what you already have will wipe your device.
As far as roms go as long as the rom is for a 955F or FD you can flash it regardless of CSC for the most part although some roms allow you to choose CSC during install.
Enjoy your new device!

Hi,
Can I flash rom of G955F/FD to G955N, and why if not. cause I saw some Rom can flash G955X.
Btw, is there any way to edit MEID Cert without using Z3X Box?
Thanks!
Yes you can flash G955F ROMs. Just make sure you have the proper CSC file for your region, to flash after installing the rom,. Your Regional Sim card won't work without it. There are many tools in the S8 Developer section. Some of the Roms already have built in multi CSC files, so read the OP of each ROM you may be interested in.
DONT clean install the OREO release (like I did), as it locks the "OEM unlock option.

Thanks @Amd4life for the answer.
So after flash Rom G955FD, I can use dual sim function?
Do you know anyway to change MEID Cert without Z3X Box?
Yes on the dual SIM, with the correct CSC. I can't answer the second question, unfortunately
is there any way to do this and upgrade to oreo without breaking knox?
im on 955n with stock aql3 last update. and if there is a way to update without having to wait for oficial release for korean models, that would be amazing.

Hi , my XZP came with an unlocked bootloader, and the firmware is the one for my country, but is a lot bloated, and also I don't like the boot animation, and shut down one .
My question here is this , my firmware supports VoLTE , if I flash another firmware will i lose that option?? If yes, then what archive do I need to avoid in order to flash my device without losing the VoLTE option.
Thanks .
Anybody??
Also if I have my bootloader unlocked, how do i root the phone on Android pie ?? My firmware is
47.2.A.10.107
Well i flashed a german customized firmware,and excluded modem.sin from the flash, everything went smooth and i have the VoLTE settings.
I think that i need to call to my operator in order to have VoLTE calls because when i make one, it shows me HSDPA.
Also when i excluded the modem from the flashing, i was expecting yo have the same modem, but no, just look at the screenshots.
And finally can please anyone point me in the right direction in how to flash this device with this firmware : G8141_Customized DE_1308-5289_47.2.A.10.107_R6C
Thanks.
