Let us know if it worked for ya!
Will it work on samsung a9 snapdragon 660?
Worked like magic for me. This video saved me. Million thanks ??????
Worked brilliantly on my EE locked S8+. Pie update literally ruined this phone. Lags, stutters, very poor battery even after a week of use. Thought I won't be able to downgrade due to bootloader update but gave it a go and was lucky! Got my snappy phone back:) Cheers for the video.
Please respond waht about the last box (USERDATA) you didn't but anything on it should i keep it empty?
Hi, i'm using an S9 model SM-G960U, does this method still works since i have the latest update in April. And do i have to root my phone to downgrade it because i have apps that won't work if i root my phone.
is there any way to do this on s10e?
Hi thanks for the video but I am not a technological person obviously as I don't know what the hell you're talkin about so my question is to anybody that will answer. if I bring my s8 to a cell phone type repair place would they do this for me question mark over this be considered you know a real bad thing legally or otherwise morally maybe? I can't stand this Android pie I can't do it anymore I'm going to throw my fucking phone out the window soon if I can't get it back. Please take some pity on a senior citizen that needs help thanks a lot really.
Hello, I can remove Pie with this firmware? G965FXXU4CSE3. Thanks
The firmware site is a joke.
I tried to download and said that I did that twice, sooo where is my file?
Is this method now obsolete?
Hello! I have a question, is it possible to encounter such malfunctions after downgrading the previous android version? TIA 🙂
Welp. Its time to say Goodbye to my phone. Its because once a upgraded to 9.0 (Pie) I couldn't do anything. Now I consider it a clock!
To download firmware guys, go on updato.com and look for firmware. It gives every variant of every country without restrictions on download speed on sammobile!
This fixed my moisture error on Android Pie 9.0 on Note 9. Downgrading can fix your phone guys!
Bro I need your urgent help!! I bought my S8+ (6GB variant) from mainland China. The language was set in English but however the phone dialog app has still stuffs in Chinese and even the weather app. Now if I download a firmware suppose from European or US S8 firmware, will it resolve my issues??
Galaxy A20
I keep getting a fail
sw rev check fail bootloader device 6 binary 5
Pls no pc
I can see you don't reply to most questions, but after the Pie update on April 10th, which raised the bootloader number to 3, this won't work on a lot of devices anymore, since most of them come with a factory Oreo 2 and you can't downgrade from 3 to 2. It would be nice if you'd comment on this.
hi I was told with update 3 of pie this no longer works. something about the latest patch they changed the binary? Is that true? is there a work around? thanks – thank God I rolled back last month!
Hi, I have a Samsung Galaxy S9+ SM-G965u with Android 9 (Pie). I am all set and ready to go ahead but I am wondering if I will be able to do it on my phone. I have read from many sites the the SM-G965u has a locked bootloader and thus it is harder to root (the reason I am downgrading to 8 is because there is a root method not available in 9). How should I proceed in downgrading, and will the locked bootloader affect my chances of failure/bricking my phone if I choose to proceed?
Baseband Version Will Changed After Downgrade Plz Tell Me
I wish you could help me, I have some trouble with this
Hi, i have a note 8 and for some reason my phone is restarting every time i hit "start". It goes into download mode fine, I hit the button, the furst box says "pass" then the phone restarts. Here is a screenshot of what it the program says. https://drive.google.com/file/d/1hU1-dfxFHE4FrdrEFM7_z_O6RoEA9Zfo/view?usp=drivesdk
I tried 2 different cables and usb ports so i don't think it's that. I tried googling and nothing came up.
Trash doesn't work
Was anyone else stuck in a boot loop after this? note 9 T-mobile
How can I downgrade using just only my phone?
I got sw rev check fail (bootloader) device 4 binary 2 sad
For some reason, sammobile will not let me sign up. I entered all the fields correctly but it keeps saying that the two email addresses don't match even though I entered the same exact thing. How is this happening?
i cannot download the firmware ???
Will all the functions work? And can i upgrade?
pls. consider opening a donation link : patreon/ paypal. u are a lifesaver !
Thank You a lot!!!
I use my phone for wifi internet connection, once i download all i need will i need the internet to download the software to my phone?
Worked like a miracle!….many thanks….Actually Call Recording is my primary concern which got disabled in Pie. So wanted to downgrade to Oreo. A very easy to follow guideline video. Thanks mate!
Thanks! Your methods worked, but I had a bootloop issue that was remedied by wiping cache and factory resetting. Also, to anyone trying this, Samsung Switch didn't put all my apps back so I had a few that I had to hunt down like Health and Recorder so make sure you have a list of apps you have (easily done with an adb command 🙂 ).
For my country I am getting only 8.0.0, can I choose another for 8.1.0?
2 questions
first i have an unlocked note 8 via third party services will changong the rom relock it
2nd should i download the unlocked or locked rom ?
thanks a lot! it was a little trouble at first kept getting stuck @ 32% when starting up and then kept restarting, but i just kept trying the process over and over until it finally worked. thanks again. 🙂 what i do for PRO MODE VIDEO! 😀
Is there a way to root a note8 sm-N950U that was updated to pie?
is there any way that I can contact you, it says all threads completed but fail
I think it because of the frp lock
