my android 12 bootloader number is 4 any way i can downgrade to 11 that has bootloader 3.?

@user-bf6bt9vi5h 11 месяцев назад

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

@TheSenseiwong15 2 года назад

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.

@OfficialXtraload 2 года назад

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.

@TheSenseiwong15 2 года назад

@@OfficialXtraload This android 12 is full of bugs. Roll back to android 11 one ui 3.1 was the best prescription ever, Personally going to hold back until i start seeing pos feedback. Android 12 is half baked constant bugs like apple rushing out updates with new features without really ironing out existing bugs.

@TheRealAndroidDoctor 2 года назад

Can i get a AMEN🙏

@ItsFalcon55 2 года назад

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)

@AndroidDoctor does this work if you backed up your phone with Android 12 UI 4.0 and if you have the official version (not the beta)? I'm also debating on whether or not I want to stay. The Pop Up View is really buggy for my app and you can't play Vids in the background if you close out the Pop Up View unlike before. I want to hope they'll fix it but I'm not sure.

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.

Once you downgrade your phone can you get back to the latest version of Android? I mean would you have access to get the latest version of Android from the Software upgrade option on your phone

@itsyort 2 года назад

what is the purpose of downgrading then???

@amanjbl56 2 года назад

@Zerotwo Osu to avoid lagging and a lot of green screens due to come on during the filming Edit And I know that they all come cause of using not official software updates.

Not sure if you're still keeping up with comments on this video but I was curious if this has been used on bootloader version 4 of Android 12/UI 4.0 on S21 ultra with success? Needing to downgrade to a prior version of Android 11 so I can unlock the bootloader and root.

@TheRealAndroidDoctor 2 года назад

If u have done a few system updates since upgrading u might have the new bootloader so downgrade wont be possible ,however only true way to find out would be to try the downgrade some say it still worked for them

@@TheRealAndroidDoctor I went through the beta program from the day it opened, the November update was the "stable" version update and unfortunately I took the Dec update a couple weeks ago so only 1 update since the not so stable version came out last month.

Ok. I'm done taking any samsung updates so once I have time I'll try the downgrade and see if it works. Samsung used to be great until they decided everything is a race and it's turned their products into crap they push out without any regard as to whether it's ready or worth using.

Learning now that the OEM unlock option is gone and I can't even get into the bootloader, fuck you Samsung.

Hi, my phone is s21 5g and I have installed the December 1 security update. Can I also downgrade? Could something happen to my phone?

@TheRealAndroidDoctor 2 года назад

Feel free to try hopefully that update doesnt have the new bootloader that prevents the downgrade

@TheRealAndroidDoctor 2 года назад

U will be able to update as normal after by going to software updates
