I hope that the twrp encryption part for 15.1 will be fixed soon, as I would like to use it as a backup for such upgrades (14.1 to 15.1).
Just to make it 100% clear: that can be done by selecting both ZIPs in the right order in the same install process, right?
After you selected a ZIP for installation in TWRP, you can choose “Add more Zips” to select another ZIP to install right after the one before in one go, and so on … there’s a limit of 10 Zips I think.
so what else ?
already do what now
Donate more, obviously ?
Edit: Oh, there was something else, too …
What are the differences between 14.1 encryption and 15.1 encryption? What are the advantages of one over the other?
According to this …
… there’s a possible change from full-disk encryption (been around since Android 5) to file-based encryption (since Android 7), but I’m not in the know whether this is the root of the current problem or not.
No. Or at least it’s not known yet why twrp cannot decrypt partitions that are encrypted under O. I am not yet sure if twrp can decrypt 15.1 if the encryption was done under 14.1.
It’s possible (up to probable) I get something wrong … but this here sounds like somebody fixed that for the OnePlus 5T in January.
Edit: Ok, nevermind. The more I read about it, the more it seems finding another convenient backup workflow for 15.1 or betting on Fairphone to get Android 7 ready with a working TWRP are the ways to go for me …
twrp 3.2.3-0 is released.
According to the notes it doesn’t fix Android 8.1 decryption.
It does fix the broken automatic OTA installs.
Great job everyone, not least @chrmhoffmann
Perhaps a guide/wiki for installing Lineage 15.1 summarizing everything (TWRP, Modem-zip, getting GAPPs or alternatives) would be nice?
EDIT: Never mind, there is such a thing, I forgot (https://wiki.lineageos.org/devices/FP2/install). Is there anything in there that needs updating to account for Lineage 15.1?
Does that mean that if you have encryption on 15.1 you can install OTA updates? But if you wanted to use TWRP for anything else you still can’t decrypt…
Or do you mean encryption prevents OTA updates still even on 15.1?
That. Details are in the other topic.
So I guess we have to wait one week more for the official nighlty
I noticed a problem with the headphones during a call. I can adjust the volume and the GUI shows it whereas the intensity of sound does not change a lot from minimum to maximum values and it always remains quite high.
