Fast uploading pixels to screen

I'm trying to upload dynamically generated picture to the screen with minimal delay, frame by frame. I have used glTexSubImage2D but it's delay is big. Haven't use PBO because it is not implemented on some devices (requires GLESv3). GraphicBuffer binded to a texture (DMA) is a bit faster, but it downloads the full picture to buffer on every lock() call. Is there a way to upload pixels to the texture (or native window) rapidly without downloading the buffer back? Just for uploading some pixels to the display?
