Dear all,
for about two weeks I have been trying to install Lineage on the
Gemini but really got stuck.
So far I used the partitioning tool to select various combinations of
OSes. I mostly tried a rooted Android on the first partition,
downloaded all necessary files, unpacked and installed with the
flash-tool. It always works fine. I can boot all partitions.
The next step is trying to install TWRP into the recovery partition. As
a first step I install Magisk to give the TWRP app root
access. However, making Magisk modify the boot image always gets me
into a boot cycle which does not stop unless I boot into another
partition or flash everything from scratch.
Since Magisk can also be used without changing the boot image I use it
to simply give the TWRP app root and try to modify the recovery
partition so that I can boot into TWRP. Now I get into a boot cycle as
long as I boot into recovery. Booting the original rooted Android
works fine.
It seems that changing a boot image, no matter on which partition gets
me into a boot cycle: Device trying to boot, vibrate, going black,
trying to boot, ... and so on.
Does anyone have an idea how to get the TWRP boot image installed?
What is my mistake?
Thanks in advance and cheers,
Thomas
