Happy to help

It’s for official firmware only you can’t just use any OS

Find your model here and download it, best of luck galaxyfirmware.com/

Installing an older version of android likely won't do much for web browsing. Older versions aren't going to work well with modern sites/apps. If this a device you actually use day to day it's definitely time to upgrade.

@@TechOut nah i have newer devices i just have nostalgia for this one, i meant that it struggles to load google and most applications tend yo crash if i have more yhan 3 tabs open, i just wanta install an older version simply so the device will function better

If you feel comfortable doing it then sure why not.

Flashing the software will not remove a Google account lock. It's going to check for the lock during setup

@@TechOut well, this seems to be the method being thrown out there by a lot of other channels. I've tried every method I can find. HushSMS, the KZfaq workaround, the emergency call technique, et al.. Any suggestions?

Unzip the firmware download and they will all be there.

@@TechOut how do i do that?

No you need to use download mode

You can only flash official Samsung ROMs with Odin

I'm sorry I didn't make myself clear. I know Odin is only for flashing Samsung, what I was wondering was if it would be possible to install a Samsung rom for the same model but the idk European or South American version that is able to have the bootloader unlocked in developer options. So could I use Odin for that?

@@joshuaguillory6647 Pretty sure you can do that with a locked bootloader yes

To change CSC you need to use patched Odin. Looks like you also have an Exynos device. Anything here is for Snapdragon so there may be differences.

You do not need an unlocked bootloader for download mode this is incorrect. You can't unlock the bootloader on US devices. You can enter download mode to flash official Samsung software with it locked.

Should be one of the extracted files from the zip folder

@@TechOut I think he's asking where you got the zip file from originally.

I tried it many times, seems as if you have android 12, you cant go back anymore. Smart Switch also doesn't show a "downgrade" button anymore. I have tried several good firmwares for my S10 (SM-G973F) to no use. Odin just gets stuck on boot.img and that's that. If I try to flash firmware of a Android 12 version, it works. but if I try Android 11, 10, or 9, it just doesn't work. Many forums say you cant go from android 12 lower. So stupid... The new One UI 4 (Android 12 based) ruined my Galaxy S10 speaker - its rattling, buzzing, is distorted. The top speaker is OK

EDIT: It seems, even tho I'm writing a few second later, that after days of seeking a resolution to this - Rolling back / downgrading android 12 to 11, 10 or 9 because of bugs and broken speaker on my Galaxy S10 - a dude has figured this shit out!!! You need to not only know and find the correct firmware for your phone, e.g. my S10 is SM-G973F (which I have known), and the correct country CSC code, e.g. my is ORS (also known), but out of all the "correct" firmwares, only the ones with the 5th letter from end work: Example: My S10 (SM-G973F) with CSC country code being "ORS" had like 40 firmwares for Android 12, 11, 10 and 9 (being the last, not 8 or older). The approximately 40 firmwares were like G973FXXUEHVC6 or G973FXXSCFUH5 or G973FXXU2ASF3...but...ONLY the G973FXXSEFUL1 and G973FXXSEFUJ2 worked for me because my phone had a similar number in settings/about phone/software info e.g. G973FXXBECDFJ and the 5th letter from end was "E" G973FXXS "E" FUJ2 or G973FXXS "E" FUL1 ------ so only the ones with the "E" as the 5th letter from end worked. Tried just now and rolled back to Android 11 - SUPERB FEELING AFTER DAYS OF STRESSING Tho my issue with speaker persists so perhaps its also on Android 11 or...its a faulty speaker and new one is 27$ + back glue for back glass is 9$..damn, the money :P

@@ancientslav4863 pls help

@@oddfutureboi4330 What can I help you with? Explain your problem. BTW, I bought the S10 speaker for 27$, replaced it myself, and since then no issues

If you don't know what update files are you have no business using this

@@TechOut Thanks for being totally unhelpful and demonstrating your shitty attitude.

It's not a shitty attitude. You have no business doing this if you don't even understand the basics

I'm not being an asshole. If you don't know basic things like this you should not be messing around with this. If you do this wrong you can brick your device.

The files are all labeled to where they need to go

There seems to be a prevailing attitude among developers that they don't really want to teach people how to do this, they should just know. Believe me, I've spent a lot of time on XDA developers and this is the attitude I get aaaallll the time. How do they expect people to learn this? You would think they'd want a richer base of developers.
