Downgrade One UI 2.1 to 2.0

[Guru-Sandhu]

I'm using a Note 10 plus and a few days ago I upgraded my phone to One UI 2.1 and after that My phone became very laggy . I bought this phone only for gaming as I have Youtube Channel but now Three of the major games I used to play have become unplayable. PUBG Mobile is locked at 40 fps and Call of Duty is locked at 30 and Asphalt 9 is stuck at the loading screen. I have tried alot of solutions but nothing seems to work. If anyone to could help me downgrade back to ONE UI 2.0 as I can't wait for the new Bug free update.

Mobile Model is SM-N975W

Please inform me if it will void warranty.

I have tried reinstalling games , Lower graphics , wiping cache , and even factory reset.

Yes you are wrong. You can downgrade under certain conditions.

You can't unlock bootloader in developer setting (unless it's an Exynos chip). This method doesn't work for Snapdragon chips.

Please expand about " the certain condition " because I use latest odin with official software but can't even revert back into last month software. But it is successful if I flash using current software or newer software..

 this is happen on my S20+ exynos. 

[CHMultimedia]

Because they increased the BL fuse. Previous S20 Exynos LTE firmware is extra buggy and they probably don't want anyone to revert to it. ATD5 is BL 2. Previous firmwares were on BL 1

😅 Just a reminder @CHMultimedia, I'm still waiting.

[CHMultimedia]

Yes, now I am getting my tablet from the repair shop. I was uploading the files, but had to go. I have them, they just have to be uploaded. Currently on the bus and I don't have unlimited data so I'll have to make you wait a bit more

[Guru-Sandhu]

 have you reached home ? 😅 I'm sorry but by telling me you have the files. You've made me restless. 😅

Don't wait for @CHMultimedia...

i just trow him out of the bus after having broking his legs ...😇 BUT like i am a good samaritan, i put a mask on his face , i don't want him to grab covid-19

Sorry, I had to deal with some other stuff first. Here are the files.

Okay, go to your computer and type this in your browser: http://chmulti.ca/N10P-BTB3 (http:// not necessary)

Download everything there. You'll probably have to unzip it, do it if necessary. If done correctly, you'll have something like Image 1.

Open the Odin folder and open the Odin executable. Disregard any warning. Click on the AP button. In the window that appears, navigate to the folder you've downloaded and select the file that starts with AP (Image 2). The file will be processed. This step will take a while.

Repeat for BL and CP (select the correct file, BL for BL, CP for CP). For CSC, select the file named HOME_CSC. Leave USERDATA blank.

Now, do a backup of your phone, just in case.

After that, turn off your phone and hold the Power and Volume Down buttons (Image 3). There will be a teal warning screen. Press Volume Up. Plug your phone to your computer and hit Start.

Hi CHMultimedia, 

I have the exact same issue, wanting to downgrade back to One IU 2.0. 

Do you have the files for a Samsung Galaxy Note10? My model number is SM-N970F.

Cheers,
