a website called androidexplained claims that it's possible, any idea ?
I have G920I model with me, there is no way to downgrade ?
Official stock firmware is only 5.0.2 ?? Is there any 5.1.1 ?

You can get 5.1.1 firmware at sammobile website. if it is getting failed means that particular ROM is not compatible with your device.

Yeah we know that trick but once you flash stock its NOO ! that trick is not working after flashing the newer bootloader ( its like take 5.0.1 bootloader place it inside 5.1.1 rom then flash it with odin ) so can flash 5.0.1 rom later but if you flash 5.1.1 ROM with newer bootlader its bye for 5.0.1 rom...you get it ? But why the hell you wanna flash old rom anyway ? Its lagy and makes your phone hot like fire...bugs...
