My phone auto-updated to Android Pie and I don't like it. Can I flash it back to Oreo with Odin? How would I go about that? Thanks!
(Sorry if I posted this in the wrong place, I couldn't find the Note 9 board)
You would need to locate the Odin and appropriate files for the Note 9. You can take a look HERE

Hey so.. Phone's root bugged out yesterday and I downloaded twrp and decided I should upgrade it to Android 8.0 then root it. After many hours of failures I managed to flash a 8.0 but I couldn't make the CSC to work, since my phone is region locked to another country so I decided to go back to 7.0 and try again.. but now here it gets complicated because I really don't know what to do. I'm not sure how exactly to go back from 8.0 to 7.0.. Can someone give me detailed steps on what should I do.. I'd be very grateful!
PS. I don't know if I'm posting this in the right forum thread.

Same site, or sammobile can be used to get the firmware files to flash with Odin
Note: The last version of 7.0 locked the ability to downgrade, I haven't gone to Oreo so can't confirm, but it ability to downgrade may also be removed from Oreo.

I can confirm, downgrading from Oreo 8.0 to Nougat 7.0 is possible, even without tripping knox.
It's just flashing the previous firmware with odin and factory reset the phone before first run and you're fine to go
With the new betas coming out there is defetly going to be a few people that are going to soft brick their devices installing them. Just like I did today.
Fortunatly I foundd the right firmware after a few hours of searching.
If you have flashed Firmware: ZSB9 from the Beta 4 and if for what ever reason you are locked out this firmware should do the trick
All you need to do is flash it with Odin and you will be back on the Sweet Oreo

This is for the S8 G950F
So nothing special is needed?
Just install oreo over pie like .... if I wanted to install stock os?
.I just want to share my experience with the firmwares (G970F).
First im not against with any updates for the phone but I accidentally press the update for the latest which is the ASJA (Philippines Carrier) and i realize it comes with a new bootloader which is S3 and the stock is U1.
Is there anything I can downgrade the bootloader so I can downgrade the complete firmware also? I want the stock firmware the first one (March 2019) because of my own preferences and I just want to stay with it. Any ways to solve this even on the near future? Glad to hear some ideas. Thanks
I have a similar question. After the recent Feb 2020 security patch update, the bootloader has been changed from 3 to 4. I so wish i had not updated. Is there anyway to go back to Android 9 which has BL 3 via Odin? Help would be appreciated, thanks.
im not sure its possible, moving from u4 to u3. the only possible solution o go back to android 9, is to find android 9 firmware with u4 security bit

Since the j7 prime never recieved any bootloader upgrades it is possible to downgrade. I would suggest upgrading to oreo however,or maybe installing android 10 custom roms. anyway, to install stock 7/8 go to this link and enter your device model and country and download the latest stock firmware for you. then download odin . once you have both downloaded, unzip both of them, and open up odin. When you get you should see ap, bl, cp,csc . press the 4 buttons mentioned before and go to where you extracted the stock firmware, and you can select the appropriate file. Then boot your device to download mode by holding volume down, power and home button at the same time for 5-10 seconds. press continue. Then connect your phone to your pc, and press start in odin.

oreo is the latest official firmware recieved by this phone. There is no official android 10 rom for this phone. Yes you will likely lose all your data.

You can flash firmware of any county, since is for the exact same model you have (ex: SM-G610) there's no problem. But keep in mind some have bootlogo/apps from operator, and/or extra functionality s/bloatwares.
There was a huge performance drop on Android 12, so I want to downgrade to Android 11.
Can I flash the file mentioned in this thread (https://forum.xda-developers.com/t/asus-rog-phone-5-raw-firmware-flash-file-fastboot-ww-rom.4268331/) on a locked bootloader?
Hello, I suppose you are on WW-31.0810.1226.91 firmware, so in order to go back to A11 you should use the provided firmware from ASUS, which is named ''Version Android 12 to Android 11''.
You download it from this page https://www.asus.com/supportonly/ROG Phone 5 (ZS673KS)/HelpDesk_BIOS/ and will have this name UL-ASUS_I005_1-ASUS-99.0840.2201.226-1.1.102-user.zip and you rename it to a later version like UL-ASUS_I005_1-ASUS-100.0850.2202.227-1.1.159-user.zip that is a completly arbitrary name but will allow to install an older update over a newer one. I can not guarantee this will work or doesn't break your device, because with RP5 is a matter of luck.
Wish You good luck and let me know.
