but the "samsung galaxy s21…" phone have android 11 off the assembly line - you could just reset it to default factory settings🤷

Massive respect for this tutorial, just injected it. God Bless your a life saver, 12 & 4.1 should not have been pushed out its half baked made a £1200 device feel worse than any handset ive ever owned they bruk that update up...so heads up if youve had the 2nd Samsung hotfix on 12 the security patch is still Nov and this method works...biggup. Respec from Hudds thought you was at Dalton ends and not Liversedge. Thumbs up and re subscribed as i thought you had dissapeared...youve changed your channel name. Respec!

Upon updating to 12 / 4.0/.1 My samsung S21's lower motherboard stopped connecting to my charger component (lower mic / sim). Hoping this fixes the issue otherwise its a $900 charge and Samsung wont cover it because I broke my screen a few weeks later cause I was waiting for an update to fix it.

Mate i just updated my Note 20 Ultra to Android 12 with the latest available security patch from december and it is still(11th january) buggy af. You can have the best hardware on the market but it zero worth when you have a unrealiable software behind it. As you mentiod over 1000$ for a device that feels worse than a fkng handset.

To set the phone in download mode, turn off the device and press both volume buttons (+ & -), then plug the phone to the computer.

I basically updated my software 2 times after android 11 and I'm currently at the 2nd version of android 12, so when I downgrade to android 11 so I need to downgrade from the 2nd version of android 12 to 1st version of android 12 first? Or I can just downgrade for the 2nd version of android 12 to android 11 (I'm sincerely sorry if I made this complicated, English isn't my main language)

Ty for the tut. I feel unlucky with 12. I only want to know if I could get any problems if I dont wipe userdata. Edit: I get an error that my phone cant load android system.. what now? Ok I had to do a factory reset after downgrading with "home csc".

One question: will unlocking the be bootloader necessary when performing downgrades like these? I only have experience doing system upgrades via Odin, but not downgrades......

I bought my Samsung S21 Ultra 2 days ago and I want to downgrade it because mine came from the factory with Android 12 installed, the problem is that the OpenGL driver for Android 12 is damaged and I just can't play on emulators with the option of OpenGL, there is the option to play by Vulkan but it is slower and speed in an emulator is the most important, that's my reason for downgrading from Android 12 to 11.

I tried to reboot to Boot-loader exactly how you did it, but it keeps going back to boot-up to Android. I am on official Android 12/ US carrier unlocked S21 Ultra.

Tmobil and the s21 are averaging 2+ updates per month. Ridiculous. Some of these updates contain bloatware. A security update installing unwanted apps on your device is a bunch of crap. I don't know if it's tmobil or Samsung doing this so I'm forced to not trust either. I paid $1000+ for a device and service I have no confidence in. How many updates are necessary in 1 year? 24? 36?
