Hi,
I have a Uniwa A19S phone (mt6737T, kernel 3.18.19+, Android 6). Since my original firmware system partition is infected with a trojan and there are no firmware updates expected, I would like to port it to the Unihertz Jelly Pro 8.1 (same chipset and same kernel), in order also to upgrade to Android 8.1. On the Internet there are too many tutorials very different from each other and I'm very confused. Can somebody please help me figure out what files I should move around? Maybe give a hand?
I uploaded both firmwares here: https://mega.nz/folder/hUp00DgL#XyhdTud2EdeqJidcQeNHHQ
Thank you
