Flash the a5y17lte twrp NOT the a7y17lte. That's why your screen is unresponsive.Hello,
I try to upgrade a Samsung A5 2017 with lineageOS 14 and TWRP 3.1.1 to lineage0S 16.
TWRP 3.1.1 refuses to sideload the lineageOS 16 image because it says that the image is for 'a7y17lte' device, and my device is '.' .
The upgrading instructions says that if TWRP refuses to manage the upgrade, I should install a newer version.
But, whatever the TWRP versions available on the official site (as of today, 3.2.3, 3.3.0, 3.3.1-0 and 3.3.1-1) that I install using heimall under linux, I have the same issue: once the phone boot to TWRP, the splash screen appears, showing the right TWRP version number, and then TWRP asks for the key to decrypt the data partition, but the touchscreen is non-responsive, making TWRP unusable.
When I reinstall the TWRP 3.1.1 version that I have backed up, every thing is good, but I'm back to my origin: can't upgrade LineageOS.
Is that a known issue and how can it be fixed ?
