Yes.
After you selected a ZIP for installation in TWRP, you can choose ā€œAdd more Zipsā€ to select another ZIP to install right after the one before in one go, and so on ā€¦ thereā€™s a limit of 10 Zips I think.

If 15.1 can just use a 14.1-encrypted data partition as @chrmhoffmann suggests here, TWRP would work already. Weā€™ll see :slight_smile: .

Ok, scrap that.

240

so what else :beer:?

What are the differences between 14.1 encryption and 15.1 encryption? What are the advantages of one over the other?

245

I wanted to know, too.

According to this ā€¦

https://source.android.com/security/encryption/

ā€¦ thereā€™s a possible change from full-disk encryption (been around since Android 5) to file-based encryption (since Android 7), but Iā€™m not in the know whether this is the root of the current problem or not.

246

No. Or at least itā€™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.

Itā€™s possible (up to probable) I get something wrong ā€¦ 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 ā€¦

twrp 3.2.3-0 is released.

According to the notes it doesnā€™t fix Android 8.1 decryption.
It does fix the broken automatic OTA installs.

Great job everyone, not least @chrmhoffmann :smile:
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?

251

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 canā€™t decryptā€¦

Or do you mean encryption prevents OTA updates still even on 15.1?

252

That. Details are in the other topic.

Hi,
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.

Once the official nightly release is available, youā€™ll simply upgrade. Google services are not included in official LOS releases (and they havenā€™t been included in the unofficial releases posted in this thread since the 2nd update).

You can install the latest unofficial build now, but youā€™ll still have to upgrade anyway to the official release so itā€™s probably worth waiting a few extra days and just doing it once.
