I’ve got an FP3 with LOS 17.1 + microG and I’d like to update it to 18.1 + microG. The first install was something of a struggle so I’m hoping for a bit of help. The little documentation I’ve found on is :
Upgrade from LineageOS 15.1 to LineageOS 16.0
To upgrade from LineageOS for microG 15.1 to LineageOS for microG 16.0 it is not necessary to wipe your data, just upgrade your TWRP bootloader and flash manually the latest LineageOS for microG 16.0 zip.
To upgrade from LineageOS 15.1 to LineageOS for microG 16.0, first upgrade your TWRP bootloader, then upgrade to LineageOS 16.0 and finally follow the Migration from LineageOS instructions.
Well, it depends: If you have locked your bootloader after installing LOS 17.1, you will have to unlock it again, which will result in data loss and factory reset.
If your bootloader is still unlocked, it will be quite as simple as in the first paragraph of your quote:
I remember that when I selected the LineageOS 18.1 update in the Android update checker, it gave me a link with instructions of what I needed to do. I didn’t have to clean flash or anything, it was just putting a zip on my phone and browsing it with LineageOS recovery I believe.
Do you not get some kind of link with instructions when you choose it in the updater?
But instead of " Download the LineageOS install package that you’d like to install" in step 1 you should instead download the relevant LineageOS for microG package: https://download.lineage.microg.org/FP3/ (so the most recent lineage-18.1-****-microG-FP3.zip).
Following all the other steps as normal worked fine for me.
No, it’s only a 3 days old install and i used the latest so I haven’t yet. I installed lineage-18.1-20211104-microG-FP3.zip so the release in itself should be safe
I tend to be pretty lazy with updating but I tried it this morning and it worked fine. Not sure if it’s a feature or a bug but when I started the current and previous versions were listed (nov 4 and 17.1), and after updating the current is there (nov 18).
