Galaxy S6 Edge FRP Lock, OEM Unlock propably unchecked

So, my friend gave me his S6 Edge+ today and told me that he's stuck with the Google FRP. I tried downgrading to 6.0.1 as I did with my S7. Yet though his S6 seemed to be on the latest update from Samsung (Nougat+Security Patch).
Now when I try to flash via Odin, the phone gives me a "system rev. check fail device 1 binary 0" error and I have to reflash the latest Firmware.
What can I do?
Help would be apreciated.

This error is because you are trying to downgrade you need to flash latest firmware to fix your issue

I don't know how to bypass the Google FRP. I flashed the latest firmware already.

tell your friend to give the Google account password. The method to bypass frp is profit not allowed to be written here as it violates terms I think.

Probably you want to downgrade the bootlader. If the firmware is A310FXXU2**** you can't downgrade. If the firmware is A310FXXU3**** you can downgrade. https://www.sammobile.com/firmwares/galaxy-a3-/SM-A310F/SER/download/A310FXXU3BQD2/132023/
Flash this.

You can downgrade a firmware is the firmware has U3 bootloader. For example A310FXXu3CQI2. If the firmware is A310FXXu2**** you can't downgrade.

My phone is j7 pro sm-730f-d/s.i installed to it j7 binary5 firmware.(9.0)now touch is no working.how to solve this issue

Hello i have a samsung galaxy s9-g960f with binary 17 i think, odin says device 17 binary 2 (or whatever i want to flash). Is there any way to downgrade it to binary u2?

Samsung's downgrade lock is an insult to users. The blatant destruction of the device is a mockery of the user's intelligence and an abandonment of Samsung's reputation.

how to downgrade from official 8.0 to 6.0

I try with Odin but it is not...please.

Try to download latest 6.0 frimware but I think bootloader is locked and it's impossible.

Have you tried with ticking bootloader option i Odin ?

I believe i read somewhere on here that you can only flash the same bootloader version as 8.0 is version 2 so the only one you can downgrade to is one with bootloader version 2 and that is 7.0 i understand. Correct me if i am wrong though,

Correct.
Find 7.0 Firmware that is at least March 2018 or newer (Binary 2 Rom) to downgrade from 8.0 Oreo

Just download the firmware for 6.0.1 and flash it in odin, I've done it several times and it works very nicely.

I'm surprised they would allow 6.0.1 firmware to flash what model is your phone sm-g935f and was it on 8.0?

BL code drops to 6.0 without code but network goes

Hello,
I downgraded to 6.0 but phone is now stuck in boot loop and i'm unable to access recovery mode.
I'm only able to access download mode.
Please how can i resolve this problem?

Hey guys, who knows do we have option like — flash fw with older bootloaders and then do isolated new bootloader flash to make older fw work?
Something like that, because i "heard" similar tricks in internet, like people are flashing modem and bootloader bins separately after downgrade flashing like from android 8 to 6. But didn't find proper instructions on that.
Is it possible? Is there instruction out there?
Yeah, oreo is better than nougat and yeah yeah new features, new updates blablabla. I just believe that every device is always better with its first software - we all saw and know how Apple does, i dont think that other companies dont do something like this...after masscopy of notches personally i dont have any doubts...why you think samsung "upgrades" this bootloader sh*t? It's the same thing like it was with iphone 4s - no downgrade option, and "upgraded" version of fw forcedly reduced the work of processor and other performances - you forced to BUY new one. Same politics in Samsung.
Well, for me marshmallow is better than all others in using S7 - it's faster and bugfree than nougat or oreo, yes it's oldy and even some basic performance features not exist, but still android 6 is the best for S7. I used custom roms but they are really buggy, badly buggy, definitely not a choice for everyday using. Oh i missed the days with nexus phones...not pixels.

Could I downgrade to 7.0 if I wanted to root? (SM-G955W)

For the past hour and a half, I've been searching the forums and YouTube (no matter how stupid that sounds) if there was any possible way to get past the 'Secure Check Fail: recovery' problem with my S8+
I've seen one where you flash custom firmware onto the phone, but that involved the SM-G950U.
But that got me thinking; was it possible to downgrade to 7.0 Nougat in order for me to be able to root my phone?

If you updated or like my phone (it came with v3) and the bootloader is higher than v2 or like my phone (it came with v3) Odin can't downgrade it. I hope I'm wrong but I went trough all if it.

No you cannot. The bootloader prevents downgrade hence the errors

Look in the part cyborg thread on s8+ device forums you may be able to root still downgrade of bootloader revisions is not possible hence the error you are receiving

Problem with downgrading S8

Hello,
Recently I've updated my Galaxy S8 g950fd from Android 8.0 to 9.0, however i found it terrible and I would love to go back to 8.0. I've read many topics and all of them states that I have to downgrade it through the Odin. I've downloaded a few softs from websites:
SM-G950F_1_20181227130827_c3nriwjmas_fac
G950FXXS4CRLB
G950FXXS4CRLB_G950FOXM4CRL1_LYS
G950FXXU3CRGH_CL14023573_QB19093103
G950FXXS4CRLB_G950FOXM4CRL1_LYS
G950FXXU1AQG5_G950FOXM1AQG5_ZTO_4file
And non of them works. Odin keep showing FAIL message, phone stuck on bootloop and the only software I can use is 9.0 ( G950FXXS5DSF1_OXM5DSF1_(SM-G950FD))
At this moment I'm downloading 2 firmwares from sammobile.com website: XSG-G950FXXU4CRL3-20181218135110 and XSG-G950FXXS4CRLB-20190128142840 and I hope they will resolve the issue I'm facing.
What am I doing wrong? Is there any other way to downgrade my phone?
Thanks a lot for replies!

Your bootloader version is v5 and all other firmware including previous pie and all Oreo firmware are at v4 . If u installed June or July update on your phone then u can't go back anymore and thus Odin keep faling for your

What about going back to 8.0 through TRWP? Impossible?
I've found this thread: https://forum.xda-developers.com/galaxy-s8/help/s8-downgrade-version-9-t3922577 and I've downloaded G955USQU5CSA4_G955UOYN5CSA4_CCT.zip

G955USQU5CRK1_G955UOYN5CRK1_TMB.zip , however when I try to install s8+ firmware through Odin it keeps showing FAIL. Damn.. No other way to go back to 8.0 than new phone?

I've found Lineage 15.1 OS with bootloader v5 on android 8.0 however I am struggling now with installing TWRP. Keep getting FAIL in ODIN and note in phone: Only official relased binaries are allowed to be flashed (RECOVERY). I've tried to reset cache, perform factory data, OEM is enabled and usb debugging as well. I don't know what's going on to be honest and after reviewing thousands of posts - I can't fix that issue.. My current software on my g950fd is G950FXXU5DSFB Android 9.0.
Is here anyone who can advice me what should I do? I would really appreciate that. Thanks!

Anyone?

Sorry can't help you with that much, it seems u did all correct steps for rooting the phone. dunno why u get only official binary message.
