Thanks for the update - I have tried to flash my polaris to the most recent PE_Plus 13 posted
I am currently running the most recent PE 12 (with associated PE recovery)
I flashed the latest PE recovery then tried to flash the rom via the PE recovery (adb siteload, as per the instructions:
https://jjpprrrr.com/pe/20230119-1051/) however I am getting the following error when I try to sideload the rom:
Patching super_dummy.img unconditionally...
assert failed: updatedynamic_partitions(package_extract_file("dynamic_partition_op_list"))
E:Error in /sideload/package.zip (status 1)
Please can you advise how to overcome this - the tread reports that other PE13Beta versions worked for them but unfortunately this didn't help.
EDIT: not sure if is important but I am still able to sideload the PE12 rom via the same method
