As my armani is currently running AICP Oreo 8.1 20180317 build and device is certified, hence, it's a Project Treble -supported device.
Therefore I tried to follow this:
and preferred to flash system-arm-aonly.img (Resurrection Remix) by XDA's phhusson
However, as the size of image file ca. 900MB while our device has only 825MB System ROM, it's impossible to flash GSI (Generic System Image) on Redmi 1S
@hemantbeast, your enlightenment regarding this matters is highly appreciated.
Have a great day.
No, you can't flash gsi on armani. Cause it's not project treble supported & not gonna be. Flashing gsi may cause bricking the device.
Running on oreo and getting device certified doesn't mean it is project treble supported.
