Flash hyper 2 stock

Then flash these

This method works and problem solved. Thank you friends for your guidance

I flashed OxygenOS A16 and it was fine, but I was using very low CPU and GPU frequencies. Because of that, in a heavy UI like OxygenOS, the device started lagging due to the low frequencies and the power-saving governor.

Then I flashed ASCP, and it worked fine. However, after flashing LOS with KSU, I faced a bug where the device would restart during Bluetooth calling. Because of that, I had to switch ROMs.

Today, I flashed the latest Neoteric A15, and it’s running perfectly—no issues at all.
