Just because you trip knox does not mean you can downgrade Most devices are equipped with a hardware backed setup that disallows downgrading to a certain point... Samsung firmwares are incremented and the 5th to last digit is the anti rollback version so no matter what you cannot flash a lower bit revision firmware than on the device

Hai .
I went to samsung support and due to issue with my s6 battery they installed with software or firmware in my mobile using odin . But they installed lower version of it not latest. I want to upgrade s6 with latest version so i downloaded
this firmware or software from samfirmware NPL-G920IDVU2DOI2-20150921115810.zip .
I have some question like this :
Will it damage my warranty?
How do completely wipe all my data from odin ? What should i tick ?
Will it brick my mobile?
Will it trip knox?
Thanks

It will: Trip Knox, void your Warranty.
It will not: damage your battery, brick your device
Do not wipe data using Odin, known to cause problems, instead do a Factory reset/Wipe cache through recovery before/after flashing the new firmware.
I suggest, do an official OTA update or through Kies, if the new update is already available. If not then it's better you wait for the new update to be available for your device

I dont know how but the PIT file used by Samsung Service center, does not trip KNOX. The one found on the page you mentioned and on Sammobile although say official but they do trip KNOX. thereby voids your warranty.
Where are you from and What's your build number?

Try to update using Wifi, or flash it via Odin if you are absolutely fine without warranty!
Tell me your build number like mine is G920IDVU2DOI2
Hi!
I'm little irritated with update to MM for XEO (not branded). So many countries got the update but Poland seems to be forgotten. I wan't wait till Samsung will release 6.0.1 for XEO. So...
is it possible to flash other original MM with odin, without increasing flash counter? Eventually, is there any way (on MM) to reset that counter without touching knox flag?
It one of these ways is possible, please prompt me which firmware should I choose.
Otherwise I will be forced to wait for OTA update, cause Samsung (at least in my country) invalidates guarantee if flash counter value is more than 0
Wait ota dude dont make mistakes...no need to rush...official MM need some more tweaks..i installed it i didnt like it wifi is slow i got back 5.1.1 right away i have 920f XEF 5.0.1 i installed UK 5.1.1 it worked for some time then i lost imei i fixed it knox tripped i have difrent imei i lost signal time to time...now i have missed up phone
Hello.
Im trying to get back to 5.1.1 but Odin gives me FAIL everytime.
What should i do?
When during the flash odin give you fail?
Try to flash THIS firmware. It won't fail;
http://www.sammobile.com/firmwares/download/63682/G920FXXU3QOLH_G920FNEE3QOL2_NEE/
It's interesting to me. Has anyone tried?. Thank you.
Hi
May I please ask why you want to go back to 5.1.1 ?
The reason is, i have 5.1.1 and i am thinking of upgrading ,but if the feedback is result then i'd rather stay on Lollipop.
Thanks and sorry for my bad english
Because it was better with me in LP and because MM missing dozens of settings and functions that were present before.

SM-G920V
I've tried the firmwares on SamMobile for 5.1.1 and 5.0.2 that are listed under my model number, every time I try to flash it with odin3 it comes up as a fail.

Verizon prevents downgrade on their bootloader.
You can't downgrade it, like iOS devices.

Shut up. It is possible. I do it all the time. Just download the last 5.1.1 firmware below the 6.0.1 from sammobile and you are good to go.

you can bypass or disable the security policies and then do the downgrade?
Thank you
Can anyone help me downgrade g920i 6.0.1 to 5.1.1 without flashing stock or without losing my data.?

That pretty much depends on the version of the phone, for example Vodafone phones have a custom bootloader, so it can't be easily modified, and even if you successfully flashed another bootloader, most probably you'd trip knox, in the best case, or brick the phone... Bootloaders are always very tricky...
I'm not sure of the model number in that case, I think it's G920F/25F (S6/S6 Edge).
In my case I have a G925i, and would love to know if it can be downgraded from Android 6... I don't have the latest patch yet, I didn't want to install it because I want to eventually root this phone without tripping the blessed knox thing.... I recall that PingPongRoot can root the phone without tripping knox, but I'm not sure of the android version that it works with.

There shouldn't be, not as far as the User Data is, as long as you don't wipe the /data/media partition, which shouldn't be the case when you flash stock FW. What is lost however, is the applications, those are lost along with their internal data, like SMS, Contacts (if stored on the phone), MMS, Whatsapp chats (recent ones at least if you didn't backup the latest chats), email app (if you use the stock one), saved games (if local), etc.
so what is the solution?
Yeah man I figured it out. I'm back on 5.1.1 now when I was on my s3 flashing stock would erase the whole internal storage. And coz s6 doesn't have an SD card I thot my internal would be wiped
Hi All
my company have some reason must use S7 for Android 7.0, we purhcse new phone but found Based version is G930FXXU3ERI4, is possible roll back to OS 7.0?
If it's a G930F them yes, you just need to firmware files and can flash via Odin using a guide like https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin
Sammobile and Updato both host firmware files.
Stock flashes don't void warranty or anything of the like.

Hi
(I've searched all the guides but can't find the answer to this question)
I recently fell foul of the FRP lock on my SM-G930F Exynos and luckily found an old stock firmware that I knew worked, but noted some advice which said to verify the bootloader version matched my phone.
Mine is RP SWREV B:1 K:0 S:0.
I found G930FXXS1DQLC which flashed ok.
But looking at all the Oreo firmwares out there, they all have S2/3 or U2/3 in the firmware name, so does that mean my v1 bootloader is not compatible with Oreo?
Or does the new firmware update the bootloader, in which case the obvious question is can you revert to a v1 bootloader?

You can only upgrade a bootloader never downgrade so to answer your question no, you cannot revert back.
From memory only the final Nougat bootloader onwards prevent downgrades on Exynos, but you need OEM unlock on to roll back if doing it from earlier versions.
Also with TWRP can't you flash whatever bootloader you want assuming you've got a zip for it, the restriction is only on Odin?
You can flash just AP without updating the bootloader, but it can cause issues. For example the MM bootloader on Nougat would make a high pitched whine instead of vibrating.
Ok so could I upgrade to BL v2 with Nougat e.g. G930FXXS2DRC3? That also seems to be the latest android patch release (Mar-18).
That way I could then upgrade to Oreo and have the option of reverting to Nougat, keeping BL at v2?
I'd like to go back to using TWRP but have been burnt before with apps refusing to work on anything other than stock and I just want a reliable daily driver!
Suggestions welcome.
