Downgrade from ARJ7 to ARJ2 on G960U running U1 firmware

Howdy all,
I have an unlocked G960U Sprint variant that I'm using on MetroPCS. Decided to flash to U1 for carrier debloat/debranding and wifi calling. Everything works well, but now I want the Pie beta on the U1 firmware. I already had the Pie beta on the U firmware before beta 1 was officially released and the carrier bloat drove me nuts. Now that the beta has come out for U1, I would like to have it...my issue....trying to downgrade from ARJ6 U1 (v3 firmare). Tried to Odin back to ARJ2 U1 (v3 firmware) with no luck....Odin just restarts the phone.....am I stuck using this one?

KNOX - Flashing different region ROM

Hi, I want to flash a ROM from a different region on my Note 9. Will Knox be tripped if I use Odin to flash a stock ROM from sammobile?
I know Samsung's have either the Exynos or the Snapdragon chipset and it's not possible to flash a Snapdragon firmware on a Exynos phone.
However, I have an Exynos Note 9 (SM-N960F) and I'm planning to flash another stock Exynos ROM from a different region (also model SM-N960F).
My question is, will Knox be tripped if I use Odin to flash a different region, stock ROM from sammobile?
Knox won't trip if only flash original different firmware
Has anyone tried it?

Docomo Note 8 SC-01K (Snapdragon) with SM-N950F firmware.

Hello,
Recently i bought a used Japanese Docomo Note 8 (snapdragon), i believe that the stock rom is tweaked/upgraded/modified to accept my local carrier in Malaysia.
I did a search and found that Snapdragon chip is only available on SM-N950U/SM-N9500 version but it appears that my phone model number in "about phone" is SM-N950F.
As far as i know that N950F is using Exynos SoC.
I am now having trouble to install and use Shealth together with others banking app or even Samsung Pay.
I checked my chipset from CPUz and it is indeed a Snapdragon but running on SM-N950F version of firmware.
this is my current firmware information:-
BL : N950FXXS5DSC5
AP : N950FXXS5DSC5
CP : N950FXXS5DSC5
CSC : N950FOXM5DSB2
HW REV : N950JPN.04
(More on details on my attached screenshot)
I downloaded latest firmware for N950F and flash with latest Odin, result is fail attempt with "secure check fail : pit"
I have limited knowledge on Samsung Note 8 firmware and hoping that you can enlighten me.
My plan is to identify what is going on with the current stock firmware and if possible to flash back to Original stock rom (CSC: XME) or perhaps any Multi-CSC stock firmware.
Or is it save to just using custom rom with bricking the device?

Question In regards to flashing.

Hi. Can I flash my s21 ultra 5g model SM-G998U(XAA/XAA/XAA/ATT) using a flash file for SM-G998U1.
Yes, the firmware for the U/U1 is interchangeable; the U generally has carrier bloatware while the U1 does not.
However, do NOT flash firmware for any other model, such as B, N, or W.
I'm from Africa a using a snapdragon model so the region won't affect me downloading and flashing the flash file

Trasform g9730 into g973u1

Hi, i was wondering if i can transform my snapdragon G9730 into the american version G973U1 (also snapdragon) just flashing the the original g973u1 firmware. I d like to do that because the american firmware is better optimized for the network where i live. if is not possible to flash all the firmware, could i flash only the CP file from the american version g973u1 togheter with BL,AP and CSC from my g9730 firmware?

The only firmware you can use G973U1 firmware on is a G973U or U1.
NEVER flash firmware for a different model number on your device. You will render your device completely inoperative. Only use G973F firmware on a G973F, G9730 firmware on a 9730, etc.
If you wanted to use the G973U1 AP or CSC, that might be possible and easily fixed, but since the CP file is your modem firmware, you could cause serious damage or problems by using one not intended for your device.

So in both the cases there is the risk of brick the device? without the opportunity to flash the original firmware back?
