Is downgrading from Pie to Oreo blocked on the J6? (Odin CHECK FAIL(BOOTLOADER) - Samsung Galaxy J6+ Questions & Answers

I have tried many many Oreo roms on Odin and they all fail with:
SW REV. CHECK FAIL(BOOTLOADER) DEVICE: 6 BINARY: 1 (or 4 depending on the rom)

Is this phone completely blocked from being downgraded?

J600GTVJU3ASA1_J600GTOWO3ASA1_ZTO

first this forum is not for your phone. anyway look at the security level if its U1 you can downgrade if you have other version with the same security level for example if you have pie and oreo and all of them is the same security level like if they both are U1 you can easily switch/downgrade between them. if its not like if pie is U2 and oreo is U1 you CAN'T Do that permanently.

New device Anti Roll-Back question

Hello XDAers, I just unboxed my Redmi Note 5 PRO (M1803E7SG) and the first thing I wanted to do, after unlocking the bootloader of course, is installing a custom ROM. But all this talk and bricked phones, due this Anti Roll-Back feature has me a little confused, even though I did my research on the subject.
My Redmi came out-of-the-box with:
Android Version : 8.1.0 OPM1.171019.011
MIUI Version : MIUI Global 9.5 | Stable 9.5.13.0(OEIMIFA)
Baseband Version : 660_GEN_PACK-1.147555.0.150932.1
Kernel Version : 4.4.78-perf+
Android Security Patch Level : 2018-05-01
Should I not upgrade and wait for my unlock pass? I have read that my version should not have the anti roll-back feature implemented.

Congralutions! You not have ARB

Yep, your device is ARB 3. You can easily check yourself with "fastboot getvar anti". Do not upgrade MIUI, or you will get ARB 4 which will make things more difficult in the future.

you have ARB3... and it doesnt matter only difference with ARB3 and ARB4 is that you cant roll back.. ARB4 have fixes and uptodate firmware.. as for custom roms . only thing is you cant use command to install twrp. you need boot command and then manually install twrp.
Thank you all for your answers, greatly appreciated! By coincidence XDA also posted this article, which helps a lot. As I have to understand, I will not need any extra "dummy" images prior to installing TWRP and as I want to install AOSP Roms only, I won't have any issues like bricking my device.
Arb 3 , you not need flash dummy antirbypass when install twrp .
Aosp rom not have firmware arb , you are safety

After unlocking BL and installing TWRP, you can still install newer MIUI roms as long as they are firmware-less (which do not include ARB).
I see.. Thank you all for the info. I now need to wait for the unlock procedure. By the way MIUI is kind of growing in me, I also think that I'm going to lose my warranty when I flash a custom ROM. But I have 60 days (give or take) to make up my mind, till Xiaomi lets me unlock the bootloader, so...

How do I upgrade to official Oreo build

I have XT1677 on retus channel. I see the official Oreo build is already launched, but not showing up when I try to manually check for updates.

Yes there is firmware available for your device both by OTA method and fastboot method just do it's as you want.

Thanks. On checking for updates, it says you have the latest software, which is weird/wrong (since Oreo is already out).
Never mind I installed the Oreo ROM from - https://forum.xda-developers.com/g5/development/stock-upgrade-to-official-stock-oreo-8-t3823598

S9 still stuck in Apr 2018 security patch, no updates whatsoever...

Hi, my Samsung S9 (SM-G960F, dual SIM) was purchased in May 2018 from Dubai (fully unlocked) and is being used in India. There were no carrier restrictions at the time of purchase, it was purchased fully unlocked.
Even today, it still shows Android Security Patch Level at 1/April/2018. I have enrolled into Samsung Pie beta, and I try everyday to download software manually, but no update has come, either in security patch or in software version. The details are given below:
When I try to update software manually by going to software update - download updates manually, it says 'The latest updates have already been installed. Current version : G960FXXU1ARD4/G960FOXM1ARCA/G960FXXU1ARD6'
When I go to settings - software information, the android version is 8.0.0, samsung experience version is 9.0, baseband version is G960FXXU1ARD6, build number : R16NW.G960FXXU1ARD4, kernel version : 4.9.59-13138374-QB17882910 [email protected] #1 Tue Apr 24 11:50:17 KST2018, android security patch level : 1 April 2018
I have even downloaded Samsung Smart Switch and tried downloading latest software but no use. The message I get there is 'Your software is up to date : RD4(INS)'
Please help. At this rate, I am not sure if I will receive any updates at all, even security patches. I dont know what is the problem.
Thanks in advance.

I have downloaded Odin v 3.13.1. I have downloaded the Android Pie firmware available in Sammobile applicable in UAE and the firmware is G960FXXU2CRLI/G960FOXM2CRLI.
Can I directly update my firmware from G960FXXU1ARD4/G960FOXM1ARCA using Odin 3.13.1 to G960FXXU2CRLI/G960FOXM2CRLI. Please advise.
Thanks.

Yea, just flash as normal, your bootloader will change to version 2 so you will not be able to downgrade back to that current firmware you are running as it is version 1

What is the difference between those firmwares?

Hello.
I want to flash latest firmware, running Syberia ROM, but I want to know what are the differences between: FW, FW-less and FW-non-arb?
Thanks.
If you are still anti rollback (arb) 3, installing the latest firmware (FW) will update your bootloader, thus you will have arb 4.
Fw less roms come without the firmware. since there is no firmware, no way to trigger ARB.
Fw-non-arb are firmware files without the bootloader part, again no bootloader so arb will not be triggered.

Since 8.12.27 is the newest rom available you can install only FW as this would not trigger ARB (Both 9.6.4.0 and 8.12.27 are ARB4)

How to get an S9 G960U1 rooted?

I tried today to root this phone in all sorts of ways, but mainly I got stuck at the first step of getting a custom recovery, I found the twrp files for my phone, but when I tried to flash the file in Odin I got an error of "secure check fail : recovery"
I tried different versions of Odin.
I also tried t use fastboot, but it couldn't recognize my device, (adb devices shows my device, while fastboot doesn't [and of course I'm in download mode])
I've tried all sorts of drivers, from universal drivers to the specific one for my device from the Samsung website, fastboot still didn't see me device...
I have no idea what to do now...
I managed to get an official stock firmware update, that's all I was able to do...

AFAIK, root isnt possible for the 960U's, only the 960F's
I think I saw someone write they were able to root it.. though I couldn't find it again for some reason...
Also, it's supposed to be an UNLOCKED phone with the U1 software... I don't understand how or why it cannot be rooted (or change to a custom ROM)...
Hope someone know how to get it done

"Unlocked" means carrier SIM unlocked. Different thing.
All Qualcomm Snapdragon variants have locked bootloaders that prevent rooting. Except the Chinese variant - the lone exception.
There was an exploit found last year that allowed rooting for one of the Qualcomm variants but can't remember which, and newer firmware may have since blocked the exploit.
Is it worth trying to install firmware (official) for the g9600 phone (China Snapdragon)? And from there if that was successful, would I be able to use CROM to OEM unlock?

nope. it will very likely fail at the Odin flash process. you can if you want to, but im betting it will fail. Hell, i even had to use a modded Odsin just to flash another carriers firmware on mine, but it worked like a charm. That being said, it was all within the same basic model info, what youre proposing isnt
I'll try the modded Odin, if its a fail, I'll probably give up
