my android 12 bootloader number is 4 any way i can downgrade to 11 that has bootloader 3.?
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!
Yeah moved from Dalton now bro lol
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.
@@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.
Can i get a AMEN🙏
I bought the device used. The previous owner had a beta version. Thanks to you, I was able to undo it. Now my apps are working again. Thank you, thank you, and thank you again.
No probs bro hey remember to like and share the video thanks 👍
@@TheRealAndroidDoctorhi, what to do when now binary number also need to be same, how to downgrade?
Like I am stuck at ldfw.img whenever trying to dowgrade. From 14 to any lower version
Thank you so much! I did all your steps and now my S21 runs 11 again. I did not like the new features of 12 and how when you reach the end of pages and it jiggles everything. Thank you, again!
No probs hey remember to like and share the video thanks 👍 also go into software update & turn off auto updates so it doesn't automatically update back to Android 12
Do you use still Android 11 on S21?
@@Drannn54 yes, I prefer it over the newer android
yes my ultra 21 has the same issue with the 120 hertz refresh rate, its dipping back and forth for me too,,very annoying ..will probably use your method
Great vid!
Yea they messed it up scrolling is is now so stuttered even at 120hz since downgrading everything is back to normal
@@TheRealAndroidDoctor one question ..if I downgrade using the method in your video ..will I have to manually upgrade back to android 12 using the method in your video once everything is ironed out or will I get another Ota from my provider ?
No u can simply update back to Android 12 using the software ota update option on the phone bro
After back to android 11, issues finally fixed - battery drain and lag! thank you very much!. sub+ to this channel!.
Awsome 👍
Were you using The stable version?
I was using the official Android 12 update it was not stable it was riddled with bugs but all is good now since downgrading
@@TheRealAndroidDoctor i am stuck on CSC EUX/EUX/EUX/ZTO. There Is no ZTO official update yet. I am thinking of downgrading because my Samsung members stopped working after updating.
Wait what is your phone mine is also having battery drain issues after updating to android 12 i hope it will get fixed in android 13 as I'm too lazy to downgrade ( upgrade) to android 11
thanks downgraded android 13 to 12 my phone has done
It was working even, I had android 12 for few weeks. Thank you, good to be back.
No probs bro hey remember to like and share the video thanks 👍
Hi, I just successfully used this to downgrade from beta 4 to get the official update and it worked. Thank you.
which official update version did you installed?
Did u not watch the video i showed and explained it all bro👍
@@TheRealAndroidDoctor i was asking jon root
cos he said it was from beta 4 to official update..
Just wondering what version was the beta 4 etc..
is it android 12 beta 4 and downgrade back to android 11?
BTW is the android 12 one UI 4.0 stable on S21/S21+?
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. So what i did is, press volume up and volume down on reboot, then it gave me the blue warning sign, then i pressed the up volume button, and BAM.. it's in boot-loader mode.
this really helped me out if you live in the usa
SAMSUNG S21 SNAPDRAGON ANDROID 12
Thank you very much!
It worked! I needed to downgrade because with the last update #Hex themes stop working.
Clean instalation and when you boot the phone the first time the phone could tell you there is a problem with the system so it will recomend a factory reset, just do that and it'll be fine.
To set the phone in download mode, turn off the device and press both volume buttons (+ & -), then plug the phone to the computer.
Some claim the downgrade isn't possible with the Snapdragon s21 variant
I recently upgraded to Android 12 and it's becomes laggy and i'm going back to Android 11... thanks for the video
Best thing to do bro , hey remember to like and share the video thanks 👍
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.
Can you downgrade to 11 if your phone came from the factory with Android 12?
It really pisses me off how terrible this update is. My phone is running horribly. Random app freezes and crashes constantly.
Oh yeah its horrible
I had a 4gb phone that ran pefectly for 6 months. When I got the update I could'nt even play the games I could have before.
Downgrade bro
today i upgrade my s21 ultra and i can't downgrade android 14 ONE UI 6.1( binary 5) to android 14 ONE UI 6.0( binary 4) because there are different binary can you help me plz?
I also have the same prob with my 21
I have not recieved a 12 upgrade notification(have S21 Ultra) I am in the US. Has it been released here?
It should be rolling out now so keep checking your software updates on us phone
@@TheRealAndroidDoctor -thanks! Great channel, by the way...😉👍
@@crimsonking8746 don't upgrade. It sucks
@@themanager1980 - thanks, I have pretty much decided on that route already after seeing this video. I usually put them off for as long as possible. They tend to fuck up all my settings and cause mayhem where you least expect it....🤟😁
Thanks for making this uncut video, you provided better support than samsung service. You're a lifesaver
Thanks again, regards.
Glad you liked it
Thanks, this worked really well! Unfortunately the version where I tried to save my old data did not work and I had to factory reset anyway... but it worked after! So I recommend just biting the bullet and do the full wipe version like he did in the video. Now I'm back to playing GearVR!
Awsome,hey remember to like & share the video thanks👍
just did this.. I worked perfectly ... Thanks for sharing, you helped me a lot
No probs hey remember to like and share the video thanks 👍
oh man, You helped me a lot. s10e work smooth again ! thx bro
very important
without wipe... system doesn't load.
be careful.
What's up brother! I was the one who liked your comment on growing a pair of balls. Lol, I got a fold 3 and am hella scared to try this! I wanna confirm with you though first. It's a US Snapdragon variant on Android 12 trying to get to 11.. You think i'll be fine man? Liked & Subscribed yo!
Some say it eont work on the sanpdragon because it has a locked bootloader however someone wulith the snapdragon version commented in the comments that it worked for them so to be honest bro im not sure if it will work for u maybe u just have to grow a pair and try
Nice video and links, i struggled a bit on the USB drivers as i was openning in Fastboot like i used to do on my older phones.
my Samsung Galaxy s7 tab is Android 12 i try to back it to Android 11 but there no cp in sammobile file is it ok?
If anyone else had trouble where trying to enter download mode, just restarts your phone. Try unplugging your phone from your computer, and turning off your phone by holding all 3 buttons, volume up, volume down, and power button
one ui 4 disapoitment im going back to 3.1
Samsung is also tryharding so that it is imposible for anyone to downgrade :/
Do you have any tutorials for Vivo?
AFTER UPDATING MY S21 ULTRA USA MODEL SNAPDRAGON....VoLte is not working....Today 7 December got new update around 200 to 300mb ......i think now it work but not Samsung is not doing anything to solve this problem.........HELP
I was on Android 12 Feb 1 security and was able to downgrade to 11 on my S20+ unlocked.
Sounds like March 1 update might block alot of things (like token for unlocking bootloader for US devices.)
Had just gotten it repaired after several months without it (badly damaged) and got the 12 update and was SERIOUSLY PISSED!
Now happy again! 😀
So it works?! I have android 12 March 1 update but the last security update is Feb 1!! I really need to fix this android 12 thing because my A52 got so much slower after updating
Did you see any battery improvement after reinstalling android 11? Did you spent at least a week with android 12 so the OS could optimise battery usage ?
Imy battey life is back to normal since downgrading ,i spent 4 days with the android 12 update i really couldnt wait a week the update was so broken
@@TheRealAndroidDoctor can you help me downgrade
This new update is draining my battery.
I'm willing to pay
I have question .Is there any problem with OTA update on samsung for Galaxy s21 ultra?
No
My phone is freezen and won't power off and also won't boot into download mode. Please help 😭😭😭
I got a FAIL message after I started flashing "check fail bootloader device". This was on Galaxy S21 Android 14 to 12 downgrade.
Is it worth it to downgrade? Does the battery backup for android 12 is not good than android 11?
NEW FASTBOOT ENTERING
while pressing volume up+ down for 10 seconds together, connect the phone to your computer and itll automatically enter odin mode. Google had asked samsung to add fastboot along with odin after the July patch.
I have an S21 ultra, after I updated it the touch screen stopped working, do you have a solution...
Hello bro. My security patch level is march 1st. Can I downgrade?
Fug i hate Android 12 in my samsung s6 tab. It was smooth and buttery before (dex) now it's laggy. Can't downgrade, oh well lesson learned. If I wanna keep my phones/devices usable for the next 10 years, i wont upgrade unless I LITERALLY face sum problems.
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".
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)
I have a question.
Can I downgrade from android 12 to android 11, and after this, from android 11 to 10?
I have Samsung S10
No hashrate improvement after downgrading, really not worth the effort.
Will this remove my phone's warranty? Planning to downgrade my S20 FE due to stutters and unresponsive touch. I also can't play the games I used to play as it is capped at 30 fps now even if I change the setti gs here and there. I even factory reset my phone twice but still, no good.
No bro doing this does effect warranty only rooting and tripping knox will bro
S20fe 5g?
Same process just download the latest android 11 for S20fe for your country and model number then follow this video to do the downgrade
And now one ui 4 is stable with good battery life, handy video though
nice joke is very bad on a52s, went from 1% every 10min to 1% every 3minutes thats samsung being dogshit with update
My problem to my s21 ultra bro didn't touch after update to android 14.
I have download already version 13 to go back the old version. But when i flashsing using odin is fail. Do u av idea? Thanks & God bless.
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?
Feel free to try hopefully that update doesnt have the new bootloader that prevents the downgrade
U will be able to update as normal after by going to software updates
have you tried to downgrade? i'm in the same situation
@@TheRealAndroidDoctor there is a option in my s20 plus oem unlock in developer option but but binary number F which I can't find in android 11 or 10.Then how to downgrade sir?my mobile is worst now...plz help me..
i Try every thing but cannot downgrade to Andriod 11....i got error that i cannot install older version
(bootloader fail)...
I did the android 12 update now I'm mad. That's why I'm here. But I have 2 main issues I haven't checked on more. But 1 is the smart view not working right anymore ever since the update. And 2 is the notification of a app on the background crashing or something. 🤦♂️🤦♂️😒
Android 12 is so buggy bro I had so many problems to mention worst issue was the refresh rate bug & the battery was dropping percentages by the minute ,I'm back on Android 11 & Everything is working flawlessly again
Which firmware should I use if I have Galaxy S21 Ultra, USA Unlocked, No Carrier?
I can't downgrade can you help me I downgraded from official android 12 to android 11. Then it wouldn't reboot and said android data is damaged please clear all data or try again. I didn't back it up but I reverted back to 12 using odin again as it was fine then. Why can't i downgrade?!
Try downgrade again but after doing so boot into stock recovery & wipe the data/cache then reboot
@@TheRealAndroidDoctor I tried didn't work. Lost all my data had some backed up. Downgraded now
But what can we do if we already make security uptdates and still doesn't work?
Always stuck on LFDW, can someone help me :(
my phone is showing the error message on the screen;

Hello there

Does it work with a52s? Does it need unlocking bootloader?
I heard u have to unlock bootloader to downgrade
Yes it should work no u don't need to unlock bootloader
Hi please tell me can I use odin without internet or wifi?
When I press reboot to bootloader it comes up with intering safe mode and doesn't come up in odin
I noticed the scrolling issue as well on mine. Also, I can't link share pictures anymore. Any way to do that or did that get rid of it?? :-(

i've joined and got an email and my account was activated but when download, it's still Say"Join to Download" please help me
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? Shady stuff. The consumer is getting fleeced.
Bro i am thinking to downgrade my A72 but i have fear that IMEI number, Serial number is erased?
I am done this thing in Chinese phone that phone is completely wipe also IMEI, Serial numbers 😑
Thank you so much bro.
is the download for the firmware supposed to take hours and hours from sammobile?
Yes unfortunaly it takes hours i left mine to download overnight

thank you kind sir !
@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.
Yes it will work
Hi Android Doctor, more power to your channel. I was wondering if I can flash an android 11 version on my s20 plus. Currently it's ruining on androids 12 latent. Plus my device is rooted. Thanks

Does it work on the final 12 release? Some Apps are crashing and the battery life is so low compared to previous.
it uses the same sw rev. it will definitely work. not so with the SW REV. different. You can check the firmware more fully at samfw. This is what I'm facing right now, how to downgrade SW REV. ?
