  1. Comment: Hello St, I was trying to port your ROM to my device but I found the ROM is a twrp backup. How can I manage that? I successfully unpacked the systems. ext4.win, but I don’t know whether to repack it back or zip it and flash. Just a small observation, I once asked on Facebook whether I could port your ROMs to my 320×480 red device, I got a way out by changing the values of screen density in build.prop before zipping it. Now I can port them without screen size issues. Thanks for the big shares.

  2. ^^ same question as loservf ..I extracted the .ext.win file and merged it with system file available.Seemed to install the os but bootloop . might be with boot.img instead ,so when porting boot.img , what do we compare in boot.img . what do we compare exactly? and also when checking split img folder. i noticed everything is named miui.img.****
    mine is boot.img.**** so renamed my stock to miui.img****.

    Thank you for for time as well. 🙂
