Hello,
I am attempting to downgrade from Android 8 to 7 on Galaxy S7. When I attempt to flash the old firmware I get the error 'Device 3 - Binary 2'. Does anyone know if there is a workaround for this yet?

Odin will not let you flashback to a previous boot loader version, you have to do it through TWRP. So either flash the nougat firmware with TWRP first or any nougat based rom, then flash nougat via odin which will remove root and TWRP.

Are there any instructions for this?
Will secure apps (Banking etc) work again after removing root?
I was under the impression you could via Odin if OEM unlock was enabled, without needing TWRP or root. https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-downgrade-android-oreo-8-0-t3821495
edit: As for banking, if you go root then flash back to stock you should have no issues. Even if you stay root, things like Magisk will hide root status from apps and pass safetynet. Your biggest issue would be the loss of Knox, which voids warranty and breaks some Samsung apps.

It is not possible as per some of the replies to that thread. I spent a few hours playing TWRP yesterday and it was not possible either.

Ok so listen, it can be done as i said but it's not easy. The choice you have of course before attempting this is to just install a android 7 custom ROM? many nougat ROMs are just stock with the bloatware removed and the boot-loader version isn't checked during flash.
Here's another way to go back, i can't guarantee it will work though i haven't tried it on an S7.
Downgrade to an older firmware with an older bootloader even if one keeps the newer bootloader on his device.
So what's how's it done?
Download the firmware file (.tar) which you want to downgrade to and open it with an archiver application (7zip). Extracts all the files to a folder and repacks them again in a .tar file but leaving every file out which ends in .bin (e.g. sboot.bin etc.). This .tar file can now be flashed like any other firmware file via Odin and it should run through it without any problems.
Hope this helps.

According to the Verizon Galaxy S5 Update Page:
Android® Security Patch Level: 2017–08-01
The current software update gives you the most up to date Android security patches on your device.

This is basically the same thing they are doing with other devices. Since Samsung never released their September Security patch due to them addressing the BlueBorne problem, they have been re-releasing the QH* updates as QI* but they include the BlueBorne patch. For some reason, Verizon didn't include the BlueBorne patch in the changelog like they have been for every other phone.
For example. The Galaxy S6, Galaxy S8, and Galaxy S8+ updates all say
Includes: Blueborne security patch
The current software update gives you the most up to date Android® security patches on your device.

Who knows why they chose to include the exact same changelog as the prior update with the same security patch. Whatever. Verizon sucks. We all know it.

Also, I'm not sure how much longer I'll be doing this though because the screen on my S5 is going bad (flickering and flashing green whenever I bring it out of sleep) so this weekend I'm getting an S8+.
so its safe to say that the new modem ql2 is pretty much the same sa the previous update?
Updated to this build from QH2, flashed in odin, then booted up, reflashed TWRP and SU, froze system updater all good. If you do end up leaving, this will just be another loss for this model as no one else is updating the stock images anymore.
Thank you for your work on this. Does this have root, and if not, do those of us with locked bootloaders have a way to keep root and safestrap?
Tell us how the S8+ goes and if you can unlock the bootloader and root that. Thanks again!

For the record, this loses root, and loses safestrap. I'm too dumb to know how to root this since I can't get TWRP on this phone, so I'm going to hope the way back to root and safestrap is get back Kitkat and then up to PB1 starting over using these steps.. This will probably be better for someone who knows what they're doing or just wants to upgrade for the security updates and doesn't care about root.

I have a 15 Emmc chip and unlocked the bootloader via this thread: https://forum.xda-developers.com/ve.../testers-required-easier-root-method-t3561529
I flashed EMMC_15_VZW_QB2_STOCK_MAGISK_ROOT.zip to my phone. I also have TWRP installed.
Now, if I understand all this correctly, I can simply flash your Developler Boatloader friendly version via TWRP? This will upgrade my OS to the latest update? Then flash Magisk to get root back?
This all seems too simple.
You will also have to re-flash TWRP via Odon.

I too followed the instructions in the thread above for a CID 15 eMMC.
I was unable to flash the "G900VVRU2DQI2_G900VVZW2DQI2_G900VVRU2DQI2_HOME_No_ Aboot.tar.md5.zip" from the OP using TWRP, but was able to do it no problem using Odin 3.12 (AP option).
After flashing that I then used Odin again (AP option) to flash the latest TWRP (https://dl.twrp.me/klte/twrp-3.1.1-0-klte.img.tar.html). I then did another factory reset on the phone (since I had already just wiped my data following the bootloader instructions) and reinstalled Magisk from TWRP and MagiskManager.
Everything looks great so far. Thanks for this update OP and for those of you providing guidance.
I have G900VVRU2DPD1 with unlocked bootloader and twrp 3.0.0-0.
Can I flash the
Developer Bootloader Friendly/No Aboot No-Wipe Firmware:
G900VVRU2DQI2_G900VVZW2DQI2_G900VVRU2DQI2_HOME_No_ Aboot.tar.md5.zip ?
If yes, after flashing, will my bootloader remain PD1 unlocked? Is it OK to have unlocked PD1 bootloader with DQI2 firmware?
Will the TWRP and root be lost? And how I can get back TWRP? Using ODIN? If root is lost then can not use flashify to flash TWRP.
If using odin to flash TWRP, then I can just flash supersu zip in zip to get root back, right?
Thanks.
I guess this is slightly off topic since it's not about this specific firmware version, but here goes ~
How do you guys go about extracting firmware/modems from stock ROM updates?? It boggles my mind lol. I'm running a OP3T now, but am working on an old device (and I still have my old S5 too). Over the years it appears people are now able to do this process for most devices and make it flashable one way or another.
I wish I understood how this gets done (and possibly figure out how to do it myself). Would love a guide / video / brief explanation with terms I could look up if it's long & involved??
Thanks for the work!

Stock ROM update is just a tar archive with files inside.
The names of the files are mostly self-explaining.
Use some tool to access the archive, like Total Commander or 7zip archiver.

Just pack what you want into tar archive and it will be flashable.
No need to attach checksum.
But it's possible too.
Say, this tar-file is flashable:

Can I reuse the same Magisk from the "EMMC_15_VZW_QB2_STOCK_MAGISK_ROOT.zip" file from the other thread on how to unlock bootloader and root, or should I download the latest Magisk and MagiskManager?
Edit 1: Okay, I installed Magisk after updating to the latest QI2 and am rooted. However, I found that I'm missing busybox and safestrap. Do I have to reinstall both of those as well or can I just reinstall busybox?
Also, QI2 lost tether/hotspot capability as it reverted back to asking to purchase the service (I'm also on the old grandfathered unlimited plan)...is there a way to get it back as when on rooted QB2?
Edit 2: Did some more research while hiding at work...so now I know, having TWRP recovery is enough and just need to reinstall busybox.
Now still need to find a way to get hotspot capability back like when on the rooted magisk QB2...
Thanks

Nah this fails on the latest U2CRED ROM with bootloader v2...
hello everyone,
i have S8+ with android 7 installed, not rooted and still didnt get any OTA for either oreo or Pie, so i decided to do it manually but i wanna make sure of the steps since it's been a while for me not flashing anything.
first thing i should know is that this update is going to wipe my phone due to the bootloader update
and about that bootloader update, should i flash pie bootloader first or just flash a stock ROM with odin that includes bootloader file ?
any help with this issue is much appreciated

If you are going to update with Odin flash full firmware. ( 4 files )
As for wiping your phone when you unzip the downloaded firmware there will be 2 CSC files.
CSC - Clean install will wipe your data ( same as factory reset )
Home CSC - Dirty install should keep your data
Always do a backup before doing anything.
Note: Make sure after you upgrade your firmware to update your apps so that they will be comparable with new firmware.
Backup First I am not responsible for anything. Backup your NVRAM NVDATA EFS to restore ur iemi .
I have Made a TWRP backup for Pie so everybody can move from Oreo to pie by Restoring Backup.
first install BL and CP of pie throw odin and then restore backup uncheck efs while restoring.

How did you root pie?
I have decided to share screenshots
I'm a us user as you can see I have volte working and I got Dolby working .
Make sure you have the latest Oreo bootloader installed this so can down grade to Oreo if I want to.
Do not flash pie modems if you do you will have to flash pie bootloader.
If you have a bootloader example
Xxu3 you need flash ap system and bootloader xxs4.
This not for flashing this build but for flashing pie on Odin
Restore.
Restoring with selected EFS damaged original IMEI.... Without is it ok. Thanks!

How do flash it though? I extracted the .zip file but it doesnt have the files to be flashed through Odin. Also I think I should tell you that my phone or rather knoxs tells's me that my phone is rooted but I've already flashed the non-rooted stock rom years ago because I failed when I tried to root my phone before and I don't know how to fix my mistake and gain root. If its not too much to ask, I would like to ask for your help, I would greatly appreciate it.

Hello, i would to ask about how to downgrade to the earlier version of the stock ROM
I already download the correct country code, variant and everything else but when i click start in Odin
It says that cm.bin fail and the process is canceled, how to fix this issue?
Thanks a lot
SM-A750GN with XID country code, here is the firmware that i use https://www.sammobile.com/firmwares/galaxy-a7/SM-A750GN/XID/download/A750GNDXU1ARIE/241618/
and this is my device firmware now A750GNDXU2ASB4
or is it not possible to downgrade? any help around this as to not void my warranty if possible
There could be a couple of things:
1. You could be using an outdated version of Odin
2. You need to re-download the firmware, try searching updato for your firmware
3. Maybe the current/latest version of the firmware installed on your phone locks your boot loader to the current version (binary version matches the boot loader)and that is why you can't downgrade
What you could try (definitely at your OWN risk) because if things go wrong you can end up with an expensive paper weight:
1. Unpack the firmware with 7zip, remove the file (cm.bin) then repack to tar with 7zip
2. You can try to flash just the AP and CSC

You can't downgrade because the bootloader is protected by Rollback Prevention, the only way (maybe) to use Oreo is to flash TWRP and wipe system data and use any custom Oreo ROM.
If you want to know about Rollback Prevention then there is a attached pdf from the Samsung Technical documentation
