Am i doing something wrong?

I was using my good old redmi 8 till today. I bought Nothing Phone (2) and i tried to install /e/os on it, i downgraded it from Nothing os 4.1 to Nothing os 3.2 becouse guide said so. I downloaded A15 version of /e/os 4.1.1 and here is place where i hit wall.

I flashed everything in same order and everything goes as intended even data wipe/factory reset but when i try to update throught ADB i get this error

Step 1/2

error applying update: 7 (ErrorCode: :kInstallDeviceOpenError Error: recovery Error in /sideload/package.zip (status 1)

After that i must flash super_empty.img and flash Nothing OS 3.2 to make phone work. I will thankfull for any help you guys can give me

Hey @OneArmedGambler

Did you check the downloaded file e-4.1.1-a16-20260718651044-community-Pong.zip to see if the checksum in the SHA256 file is the same as yours?

yes i checked and also i tried again but i just tried to install /e/OS after i flashed super_empty.img and it worked. Am sometimes dumb as brick but in guide it should say that this might be posibility
