[Samsung Galaxy S7 Edge Questions and Answers] Rakanoth:
Hello, so I'm having a huge problem right now, that seemingly came out of nowhere.

My phone is stuck on "Samsung Galaxy S7 Edge" screen logo and can only enter download mode, nothing else.

All I did was download the firmware update that popped up OTA. Something must have failed and I was greeted with a permanent freeze on that part.

The update that I've downloaded was called - G935FXXU1DQB7/G935FSEB1DQB2/G935FXXU1DQB3 with the file size of 1224.14 MB

It has failed once before but it wasn't a brick. Said something about mounting data error in a recovery mode. A day later I've tried to re-download and install the update again and this is the place I'm in right now.

My phone is the European Exynos variant, not sim locked. I'm from Lithuania, but I somehow doubt my model had the Baltics firmware as I don't think the 7.0 is released there yet.

So far I've tried installing stock firmwares from UK, Poland, Baltics region. Both 6.0.1 and 7.0 yield the same results. Different Odin versions. I can confirm that the USB ports work and there is a connection, because flashing a single random .tar file passes and reboots the phone., but does nothing for me (like installing extracted hidden.img.tar). Ends up at the same splash screen.

Every attempt to flash anything has to be with the download mode rebooted or else it doesn't do anything. (Maybe this is normal)

All threads completed. (succeeded 0 / failed 0)

When I flash the AP, BL, CP, after a while (a minute or so) I get a fail without seemingly any progress.

Complete(Write) operation failed

Usually hangs on the recovery.img, depending on what I try to flash.

When I flash CSC, Pit file, or leave a ticked repartition box without including any of them, I instantly get

Re-Partition operation failed.

So naturally this always triggers if I flash all 4 of the items.

I have also tried Smart Switch. The only problem is I currently don't have my S/N number, because some internals and all of the outside of my phone was changed under the insurance, including the back where I believe the number is found, so I've tried S7 Edge S/N number of a friend of mine. I believe our phones are different, because his firmware is from Baltic region (SEB) which doesn't even have 7.0 out. I'll try getting my S/N number through the carrier I bought the phone in. Anyway, Smart Switch throws an error about "Failed to recognize software update mode" after downloading the (SEB region) firmware and stops there. I'm afraid even my own S/N number won't help.

This is what my download mode says

I feel like all of this mess is caused mostly by the Factory reset prevention lock?

I don't want to trip Knox and void the warranty by installing a custom recovery, which would maybe help me? Does anyone have any ideas? I'm at this for like 10 hours already and desperate. Hope I don't need to give it in. No ability to even turn off the phone, what BS is this...

Can't post images yet, sadly.
