Flashing G955FXXU1AQDD over G955FXXU1AQDG - Samsung Galaxy S8+ Questions & Answers

Hi i bought a G955F from Peru (PET) and the last firmware for that CSC is G955FXXU1AQDD and i want to try the latest G955FXXU1AQDG (PHN) but if i have to take it back to repair i would be able to flash back G955FXXU1AQDD been that firmware a downgrade over the G955FXXU1AQDG?
I dont know if ill not be able for some kind of odin issue or if i can brick the device cause i had those issues with my note 5 that wasnt able to get any version but the latest via odin.
Sorry for the bad english.
Tnx
edit: also if my G955F have PET CSC and i flash (PHN), that i think comes with multiple CSC but PET is not included, wich CSC is going to be my new one?.

As far as I know you can't downgrade, but I'm not entirely sure.
Just stay on AQDG, as long as KNOX isn't void, the service center people really shouldn't have an issue with it.

Tnx for ur answer, the problem is that my s8 plus have a carrier specifix splash screen and if i ever go to repair they inmediatly will notice a samsung splash screen instead.
I guess ill have to wait for the DG version released from my carrier to avoid been stuck with the phone if i have some kind of problem.
SOLVED: as nobody tried i did and u can downgrade without issues, yay for me.

Can you trip Knox by flashing different region stock firmware?

Hi guys,
I got my new S6 from a retailer based in Hong Kong and for some reason it came with Polish software. So I downloaded stock BTU firmware and flashed it with Odin, but I forgot to check my Knox counter beforehand; I just assumed it was a brand new phone. Now it turns out that my Knox counter is tripped, and I am pretty damn sure I didn't do it as I haven't even got around to rooting the phone.
So I was wondering, would it be possible for the different region firmware to trip Knox?
I have a very strong feeling that the phone was tampered with before I even got it as the box it came in was not sealed and when I first switched it on it didn't go through the setup wizard but booted up directly in the system.
Where did you download the firmware? Give the link of rom
did you flash it by odin or by custom recovery?

Flashed with Odin v3.10.6 (can't remember where exactly I downloaded it from but I think it's the real thing).

Manually checking for an OTA update also does nothing?
The latest firmware for ROM is AQK7 with the Nov patch, so it's strange as to why you're not receiving any updates.
Try doing a factory reset, but make sure your SIM card is inserted while the phone is being reset, then go through setup and check for an OTA again.
Thanks, i will try that.
LE: I did a factory reset , i did a manual update and it says i`m on the lastest software (AQJ5 - october)
Anyone else faced this ?

Is your Knox warranty counter tripped to 0x1 by any chance?
Also, if you really want the Nov update, you can always flash AQK7 using Odin and you should be getting OTAs after that.

Yes i`ve solved it.
You need to manualy flash lastest firmware for the region you are in, then you will get updates.
I did not get the updates because phone was bought from italy and when i inserted the romanian sim card, the firmware from italy was different from the firmware from romania.
I used this guide to manualy flash :
https://forum.xda-developers.com/galaxy-s8+/how-to/official-stock-firmware-update-odin-t3582175
Hope this helps, it helped me.

I'm having the same problem with not getting OTA. The phone is a grey import from India. I'm living in Thailand, my region is Thailand, my sim is Thai. Do I have to CLEAN flash the THL firmware or can I dirty flash on top of the firmware from India? I would hate to lose all my data...

Note 20 ultra d/S firmware

I don't find note 20 ultra Dual sim firmware. Does the N986b/ds use same firmware as the N986b without loosing dual sim function? Reason I'm thinking on flashing is cause I have a xfa version and network reception is really bad and thinking on flashing btu. Do u guys think that a new firmware might help? (all other devices I get 3 bar at home and with note 20 ultra sometimes I have no network)
Check here for your required FW.
N986B is the Global Exynos model (it is Dual-SIM = DS); in case if any regions are single-SIM for this particular model (I'm not aware as such), the N986B FW will still be the same as for DS.

It's possible I think.
But..... only try other Exynos region FW (cannot flash FW for SnapDragon variants on N986B without running into problems).
Check on Note 20 threads regarding properly changing CSC.
Also, there are some .xml modification solutions that enable you to activate extra 4g/5g bands - worth a search & try.
(Sorry I don't have the links to hand, but recall seeing these discussions before on N20 XDA forums).
I'm with Three UK does this help

If I download BTU firmware and just flash it with Odin won't it just install firmware and radio software? Sorry I been away from Samsung for some years now. In past was just easy to flash a d all would work.

When you un-compress the firmware download you will get five files. Each go into a specific part of ODIN - can't mistake it - but if you want to keep data intact you will need to flash Home_CSC. This will NOT change your regional CSC however.
You also need the "hacked" version of ODIN found on this forum easily.

If I flash that 5 files will I still be able to get Ota?
When I flash should I use CSC or HOME CSC. So that I keep getting updates? I think that if I flash UK international firmware, will sort alot of my issues. It feels in my country software is never very stable.
Flashing CSC will delete your Data but flashing HOME_CSC will not delete your Data.

Will both ways I still get Ota even if I install btu firmware? (is there any benefit on me flashing the csc and not Home_CSC?)
Once bootloader unlocked I don't think you can get OTA - You'll need to flash FW updates manually.
Flash CSC for clean install.
Flash HOME_CSC if just updating FW & need to preserve user data.

Not unless you re-lock BL.
Hopefully they'll come with a solution. I would like to flash a different rom (different country) and still get Ota updates as normal. I don't wanna be flashing every month

g970n vs g970f

Hi all,
Yesterday I bought an S10e under the impression that it is sm-g970F.
Trying to flash Android 11 I discovered that it is actually sm-g970N.
Is there really a difference between them?
Should I be worried that some functions will be missing/unavailable?
Also, in the settings, it appears as g970F. How did the seller change it??
I have the same problem i tried to update the phone to the latest sm-g970f rom (figured if it's already installed it's possible)
And non of the roms flashed only when i decided to try latest sm-g970n rom it flashed however i bricked the phone and i have no idea what to do now.

So after digging into the issue since i have the same problem here are my conclusions:
1. The phone is a Korean Variant G970N it is probably a renewed phone and not a new one.
apparently it's okay for an importer to take used phones (from Korea in this case) and replace all the cosmetics but of cause leaving the used MB.
Now here is what you should worry about, in order to flash the G970F Fixed Rom (there is no way you have updates) they used a Custom Kernel which means the phone was rooted and now Knox is tripped (this not reversible).
(Download Phone Info from play store and check knox if it shows 0x1 then your phone warrenty is void and some features won't be available any more for example - Samsung Pay).
So what should you do?
Well if you still have the option i would have demanded my money back!!
One thing that i am perplexed about is how in hell is this legal?!!!
If you no longer have this option or you want to keep the phone you have two option:
1. Flashing Korean Unbranded Firmware (KOO) which is pretty good it doesn't have bloatware or issues as far as i can tell, i only found one down side for it, the phone language selection is small but if you only need English (like any normal Human) then you are golden.
2. Keep the G970F ROM but bare in mind it will receive no updates and no security patches.
I am still looking for a proper way to flash G970F Firmware over G970N for now i haven't found any internet source that will confirm it's even possible.
So how did those importers\sellers did it, they probably flashed it with a Cellphone Lab Software (not Odin solution) and used a custom Kernel to fool Knox, like i said before this is practically a crime and i don't understand how can they sell used phones as new and get away with it!!!!
I had the same suspicions....
I'll try going to the lab that sold the previous owner the device and deal with them tho it looks like I just got scammed...
Sorry to bring this up again but I've just had an idea following JerryRigEverything's video:
What if I transplant SM-G970F components from a broken device that no longer works or in use in my SM-G970N which is supposedly new.
My N device is now bricked for some reason I couldn't solve, though my suspicion is that it has to do with incompatibility with the SIM card I use.
When my device did work, it worked great! ...besides battery issues that are most likely a result of the incompatibility aforementioned.
Will this work? If so, what components do I need? I already know I'll need the logic board but as seen in the video, there are several more antennas, should I just copy what Jerry did?

Hi Vegetto,
I am from India and buy a galaxy S10e from UAE, It is showing G970F in the Phone's about but the problem is It is a G960N. Now, When I see in Sam Phone Info app there is Bootloader version - G970N, PDA Version - G970F, CSC G970F.
It is also a Knox tripped phone. Knox 0/1.
But if I see in Samsung code by typing in keypad *#12580*369#
it showing like all option in Odin:
BL: G970F
AP: G970F
CP: G970F
CSC: G970F
Does this means I can flash new Firmware on the list of SAM Mobile website, with G970F series firmware, It also showing in SAM Phone Info App that there latest firmware G970FXXSEFUL1/G970FOXMEFUJ2/G970FXXSEFUJ2.
I am in India right now.
Please help me, My email Id is -- [email protected]
It actually means you cannot flash SM-G970F the only roms you can flash are G970N.
Also if you want the phone to get security updates you must flash the original phones bootloader version, my suggestion download the G970N KOO firmware it's a global firmware. As for the knox it is tripped and there is nothing you can do about it.

How can I flash the original phone's bootloader version?
Where from I can download the original phone's G970N KOO Firmware and is it official Samsung Firmware?
How are they able to flash G970F? Is it custom Rom or do they use the original one?
I searched that my phone is using G970FXXS4BTB3 firmware which Vietnam XXV and same number found at https://www.sammobile.com/samsung/galaxy-s10e/firmware/SM-G970F/XXV/download/G970FXXS4BTB3/322678/ in an old update in 2020.
So see the attached screenshot, can I flash its latest version with odin. Of course, there is a chinese written in recovery mode installed when I go to its recovery mode for flashing with Odin.
I have a similar problem right now on my Korean S10E. Device is SM-G970N. I need it to be in Turkish. Only Themes item in Settings is in Turkish- very interesting- The rest is in English. App names are mostly Turkish Settings app name is in English.
The bootloader is unlocked but the phone is not rooted, Knox seems not tampered.
Could not start OTA update at first, I have upgraded a few versions from PC via Smartswitch. Just then noticed OTA also started downloading. The rest of the updates went on from the phone until upgrading to 12, there was a message like "All of the updates were not succesful." OTA update no longer responded. This time I turned back to Smart Switch. Update finished this time and finally I am at the latest version.
I only need Turkish in Settings. I used some ADB commands and an app called MoreLocale2. It did not work either. This has to be simple. Turkish exists. Keyboard is Turkish but not Settings. Quick links and most other things are strangely mixed English and Turkish.
How can I enable full Turkish?

Change Service provider software version

Hello. XDA is my last resort. I bought a new phone from Amazon and setting it up I saw it was with Poland Service Provider but Samsung Pay isn't available there, I would like to change it to ITV (Italy), I've tried to flash the ITV files downloading the zip file from sammobile (Idk if is the right place though) and flashing the files but with no results. Could you please help me to solve this WITHOUT tripping knox, defeating the purpose of doing all this? Currently my Service provider software version is: SAOMC_SM-G781B_OXM_XEO_12_0008 XEO/XEO,XEO/EUX/XEO and XEO is Poland Thanks!

I would suggest to take it to official Samsung service. They have tools that can change that easily without tripping Knox.

There always is a way. But given that you don't want to risk triggering Knox, I suggest you just take it to service. the way Knox is build, once is triggered you can't fix it to the former state.

Ops i didn't see this message, sorry.
I didn't get an error. From the instructions:
- Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). Do not tick any extra boxes. The only options to be ticked are F. Reset Time and Auto-Reboot.
I did that and the phone did reboot normally but didn't change anything, i still have XEO/XEO/XEO instead of ITV so looks like it didn't fail but failed? I don't know
I'm in a similar situation in the US. I had converted to TMobile variant from Samsung Unlocked U1 --> U about a year ago when TMobile was the only. I went through a lot of trouble getting the TMB to stick, now I tried go back to U1 version because I am trading in to Samsung, but I still have TMobile as the software provider version - not sure if this is something Samsung would reject tradein for
