[ROM][Android 13][UNOFFICIAL][OTA] LineageOS 20.0 for Xiaomi Mi A2 Lite [daisy]

[Its_Vixano]

LineageOS is a free, community built, aftermarket firmware distribution of Android 13 (T), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

I upgraded from 18.1 to 19.1. I just used the 18.1 recovery instead of flashing the 19.1 recovery. It worked fine.

Update: Apparently I spoke too soon. After turning the phone off and on again, it won't boot

Yeah, thx for reporting this, apparently i've just uploaded a build with privapp permissions broken

for now you can use some old build i made https://abhiramshibu.tuxforums.com/~saalim/giovanni/daisy/lineage-19.1-20220319-UNOFFICIAL-daisy.zip

i should upload a new one as soon as possible (maybe tomorrow/today)

I poked at it some more. I seemingly cannot start the Lineage recovery anymore? It just ... boots into Lineage after a delay, but Lineage can't boot. I dunno if this is related to privapp or not

All of these do the same thing:
* Hold up when booting
* Hold down when booting then fastboot reboot recovery
* Hold down when booting then fastboot boot lineage-recovery.img

This isn't my daily driver so I'll get creative to try and restore it, or just blow it away

My recovery process:
* Boot into TWRP
* Flash Lineage 18.1
* Boot into (Lineage 18.1) recovery
* Install Lineage 19.1
* Boot into (Lineage 19.1) recovery
* Flash Gapps and Magisk
* Boot into system

Avoid using the 'fastboot boot' command, somehow it doesn't works

instead flash it directly into the boot partition 'fastboot flash boot lineage-recovery.img' and try to boot into the recovery

That didn't work for me even the first time - which is why I used the Lineage 18.1 recovery to flash the 19.1 zip.

It should work, but sometimes it takes a couple of tries with reboots in between. I did not find a pattern yet, but in general flashing boot and doing the power vol+ combo should be fine. Maybe it's a timing thing, not sure. Try to switch which button you press first maybe, or try to press them at the exact same time. A bit weird, yeah

UPDATE: pressing the + button just a bit earlier seems to be doing the trick for me!

 

[Its_Vixano]

just done a test build for fixing the privapp permission issues (random bootloops caused by some normal reboots), seems fine here but i don't really trust my self

https://abhiramshibu.tuxforums.com/~saalim/giovanni/daisy/lineage-19.1-20220329-UNOFFICIAL-daisy.zip

report if something will be wrong with it

edit: Apparently it's fine so

New update released (20220329) (Checkout op for download link)
- Sync with latest lineageos changes
- Fix random bootloopos while rebooting

I dunno how we're supposed to do updates for this ROM?

I did this:
* boot to recovery
* adb sideload lineage.zip
* reboot to recovery (changes slot)
* adb sideload gapps.zip (gotta do this each time?)
* adb sideload Magisk.apk (gotta do this each time?)
* reboot to system

I did a few reboots and power off/on cycles and it didn't fail to boot. So I guess the privapp thing was fixed

Yep, that's the right way to update the rom

I have an old CrDroid rom on the phone
It is time to upgrade to a new and better 18.1 or 19.1 (the more stable is?).
I read the thread, but now I need to know and follow the correct procedure to avoid errors. I use Fdroid and Adway as adblock. Is Magisk necessary? Should the switch between the two A / B partitions always be done during installation or for updates?
Thanks to who will answer

- Just follow the instructions, everything is written here

- Should be stable enough for daily driving it, sadly i don't use daisy anymore as a 'primary' device
- I also use fdroid and adaway and they don't require root

Hi a1291762,
is the above an alternative method to go from Lineageos 18.1 to Lineagos 19.1 or should the original procedure from Its_Vixano be used? If it is an upgrade procedure rather than an update procedure (are those to be expected at all?) can you give a more detailed explanation? I have TWRP 3.5.2_9.2 and Magisk on my phone, however, TWRP should not be used for flashing 19.1 because of FBE build (what's that?). Does your procedure work with fastboot or adb? Whatsoever, though it is not my daily driver I am very happy with my Mi A2 Lite with TWRP and Magisk but I also like playing... (with 75 years).
Thanks for all of your efforts!

The OP guide seems to be written for people coming from something other than Lineage. The first part of it sets up the Lineage recovery and formats user data.

Since I was coming from Lineage and already had the recovery, I figured I could skip those steps. The OP guide says you can skip formatting data if you're coming from Lineage and I figured the recovery can't have changed too much.

I don't know how much testing was done for a Lineage 18 -> 19 upgrade. It worked for me but I barely had anything installed when I did it. Make backups in case of data loss and all that.

Something I don't understand in the OP guide is the suggestion to use the copy_partitions script. It only seems useful if your phone is somehow in an odd situation where miscellaneous A and B partitions don't match? It can't hurt to run it I guess.

can you give a more detailed explanation?

My 18->19 upgrade process matches the 19 "OTA" process. Refer to the OP guide for screenshots and details.

1. Boot to recovery
2. Sideload the lineage zip
3. Reboot to recovery (changes the active slot)
4. Sideload gapps
5. Sideload Magisk

The lineage zip is like a "full OTA" for the stock ROM. Flashing it overwrites system, boot and vendor, hence the need to flash gapps and magisk again. But the recovery only supports flashing to the current slot, hence the reboot in the middle.

I have TWRP 3.5.2_9.2 and Magisk on my phone, however, TWRP should not be used for flashing 19.1 because of FBE build (what's that?).

FBE has to do with encryption. I found this that might help explain it.
https://www.reddit.com/r/LineageOS/comments/hd534a
Booting TWRP 3.5.2_9.2 (fastboot boot twrp.img) shows only garbage names under /sdcard plus a bunch of other places (but not all of /data). So I guess TWRP doesn't support FBE encryption? I'm not sure why that matters for flashing system partitions, but if any of lineage, gapps or magisk expects to write to places covered by FBE then clearly that's not going to work properly under TWRP.


Since you have installed TWRP over the Lineage recovery, you'll have to get a Lineage recovery back on your phone before you can upgrade. Using the provided recovery should work I guess? If not, you could use TWRP to flash the most recent Lineage 18 zip, which will also replace TWRP with Lineage recovery. Part of the reason I attempted the 18->19 upgrade in the first place is because I couldn't get the provided recovery to boot on my phone.

I hope that helps.
