Hey I just wanted to ask if there is ANY way to bring 12L onto this Tablet.
Is it possible to follow this and then install the GSI?
I already downgraded,rooted and installed TWRP on my Fire. Also had to open it to make the short for the hacked bootloader.
The Fire HD 10 7th Gen likely doesn't have a vendor partition. Remember, this never launched with GMS, so these types of partitions may not be present. That's like saying that device has a vbmeta partition, it doesn't have it.
