Hi. I have an S8 with me that I can’t, for the life of me, remember the email and password that were used to set it up. I even tried the Google recovery thing, but they couldn’t find it. I was wondering if I could downgrade to Nougat because there was a glitch that would allow you to bypass the FRP. Is it possible to downgrade?
Device: Samsung Galaxy S8/G950U
Carrier: Verizon
OS Version: Oreo (8.0)/G950USQU5CRG3
Recovery Mode info:
Samsung/dreamqltesq/dreamqltesq
8.0.0/R16NW/G950USQU5CRG3

How to Remove Frp Nexus 6 Android N Security 5 july 2016
Lock bootloader,not downgrade android 6.0.1,flash rom ota via adb sideload faild,
Install app quickshortcut seach not found email & pass
¿Que?
Best guess: his bootloader is locked and he apparently cannot downgrade to an earlier version of Android 6.0.1. On top of that, he tried sideloading an OTA and that failed. The last thing he tried was installing an app in an attempt to bypass FRP, and that didn't work.
Solution to the problem: Enter the correct account information. If this device was purchased from someone else, have that someone else remove the device from their Google account.
So I buy SM-N920S 128GB Note 5, but I find out that there is FRP lock and I am unable to do anything with it! Seller is no longer responding. I was trying something like that: (youtube: ggRhkme9FC0) with no luck coz apparently updated android in this device 6.0.1 is already fixed for this. And even after install everything inside phone, the crucial app cant be run. So I install Odin3 3.12 to downgrade and downloaded firmware with Android 5.1.1 but Odin is giving me an error SW REV CHECK FAIL DEVICE 2 BINARY 1.

HELP!
II have a Samsung Galaxy S6 with carrier T-Mobile (SM-G920T) that was flashed with stock ROM G920TUVS6FRC1with android 7.0 but the security does not work, I tried to flash it with G920TUVU1AOCG_G920TTMB1AOCG_TMB with Android 5.0.2 through Odin but I have sw check fail device: 6 current: 1. So I used ASSAYYED_KITCHEN_V1.82_STABLE and create a zip with system.img and boot.img of the second ROM and flashed it with TWRP. Everything seemed to go well, the only thing that left was carrier unlock that I did it with Octopus Box but when I insert my sim the mobile go into upload mode. I need to flash it with 920TUVU1AOCG_G920TTMB1AOCG_TMB or, if exist, with any other ROM with Android 5.0.2 but for that seems that I need bypass bootloader check. Any suggestion?
Hi,
I have updated my unrooted note 8 to the android Pie but unfortunately I didn't like the new awful UI also I missed some good features in android Oreo. So, is it possible to use Odin to downgrade unrooted note 8. I'm not interested to root it, just want to downgrade it to official Oreo.
One more question, I even liked Android Nougat than Oreo. So is it possible to downgrade from Pie to Nougat using Odin without rooting?
thanks

You can go back to oreo as long as the bootloader is the same.
You'll have to do a factory reset though.
eg.
Oreo firmware: N950FXXS5CSA2
PIE firmware: N950FXXU5DSA2
Notice the 5 before "DSA2" and the "CSA2" that's the bootloader version. So since the pie and oreo firmware has the same bootloader version you can go back to oreo.
You can NOT go back to Nougat different bootloaders.
eg.
Nougat firmware: N950FXXU3BRA8
PIE firmware : N950FXXS5DSB2
Notice the 3 before "BRA8" and 5 before "DSB2" they don't match!
So the bootloader version 5 will NOT downgrade itself to version 3 therefore Odin will give you a failed error message.
To be is a different question . I have a problem, I want flash the rom with pie generic Spain, now I am in Vodafone pie and Odin always say fail, what can I do?, thanks.

What is your csc?
Spain is PHE in multi-CSC OXM
Vodafone is ATL in OVF Csc firmware.
If you used home-CSC and it fails only option is to use the CSC file (this will delete data so backup first.)
The multi-CSC oxm doesn't have ATL csc inside so you'll lose any carrier specific features (maybe???) So do some research first.
CSC Questions
Hello everybody, I've found myself in the position of needing to downgrade from Pie back to Oreo also.
My question revolves around this "MYSTERIOUS" Samsung "CSC" designation, and the difficulties in verifying what I have vs what I NEED
I have an unlocked SM-N950U1 which is currently running on the Verizon network in the United States
I do NOT have any of the Verizion specific features, ie.... "My Verizon" or even "Verizon Visual VoiceMail"
the phone has also been on the AT&T network previously again with no carrier specific features there either.
Since the "secret code" for the dialer didn't work to reveal my CSC, and there is no carrier software version entry in my about phone software information to reveal the CSC either, I downloaded one of the generic "phone info" apps and it reports VZW as currently active CSC on the CSC tab, but then on the firmware tab in the CSC version location its reporting "N950U1OYM5DSC1" and I have found zero reference to an "OYM" CSC anywhere.
I have downloaded both the PIE and OREO variants of the "XAA" firmware for my Note 8
Does anybody have any idea if this is going to be the correct firmware to accomplish this downgrade without bricking this darn thing, I have no interest in root nowadays because the minuses out weigh the pluses and I really don't want to trigger knox and loose google pay or any of my banking apps, but I really do use and need to use the call recording capabilities that still worked in Oreo, and not anymore in Pie
Thanks in advance

Hi, i just came to this conclusion! i am currently running N950FXXU7DSJ1 and odin always gives me error when i try to downgrade. no matter newest or older version. so there is no possible way to downgrade?
What if i unlock bootloader(if its possible for currently last version), change to custom recovery and install any custom rom(nougat?) and maybe flash bootloader via custom rom also? will this option be possible at all?
Hi all,
My Note 8 is currently running Android 9 (official), with baseband N950FXXU6DSD3. Given the phone is turning sluggish day by I thought it would be a good idea to downgrade to Android 8. Well, I downloaded Odion and the official firmware for N950F but Odin gave me an error. Googled and found it is probably because the baseband / bootloader is l6 and the firmware I was installing was l5. However, I couldnt find any official android 8 version with bootloader l6.
Just wondering if there is an alternate was of downgrading without tripping Knox/ Samsung Pay?
Thanks!

Nope not possible you're stuck on bootloader version 6 and there's no going backwards now!
There is no Android 8 rom with v6 bootloader? Also, if I choose OEM unlock will it still trip my Knox even if I install official firmware?

No OEM unlocking will not trip your Knox flag. However, if you install twrp and root the phone that's when you'll trip knox. If you're thinking that toggling the OEM button will allow you to downgrade backwards it's not going to happen! I personally don't know of any Android 8 on bootloader version 6. This is why we preach not to accept updates or buy a phone that's already been updated because there's just no going back once you update! We haven't found a way to do that and I don't think anyone is actually spending their time to try to figure that out either.
Ah ok. Thanks. Guess I am stuck on a laggy OS.
