Hi !
I recently got a pixel 4a 5g (bramble), and when installing, I noticed there’s a difference with respect other phones I’ve installed lineageos on, like motorola, xiomi redmi 4x (discontinued) and others.
On this pixel, and probably others, one needs to flash a boot.img, a dtbo.img and a vendor_boot.img, before sideloading lineageos. The vendor_boot.img is supposed to be the equivalent to the recovery.img.
On other phones there’s only a recovery.img to flash, prior to sideloading lineageos.
Now, on this pixel majore version upgrades I see documented only the sideload of lineageos. For other phones I usually upgrade both, the recovery.img and then sideload the new major version of lineage. So not sure if I should then should flash all images, boot, dtbo and vendor_boot, when upgrading on major versions. I guess I could, but I’m wondering.
Moreover, even on same major OTA upgrades, I’m wondering what gets upgraded, if I have selected OTA upgrades to also upgrade recovery image, would it just upgrade the vendor_boot one, or would it flash all other images?
It’s just that it involves flashing several other images, not matching the ones for other phones, :)
Thanks !
It looks like the Pixel 4 and 5 (at least) do require additional flashing compared to some other devices.
I’m not fully understanding your other question, but the instructions explain everything you should need to know to get it done.
Question is about upgrades. No issue following instructions at all, and I already installed LOS. On major upgrades the question is whether it makes sense to flash everything, just the vendor image, or nothing and just do the sideload. I’m used to flashing anew the recovery image, but on these phones it’s like split into multiple things… On OTAs, I just would like to know what get really upgraded/flashed if one selects to also upgrade recovery image on OTAs…
I see. As the instructions don’t mention flashing those additional files, my guess is that they provide them in case of a first time install, but aren’t needed for upgrade. My device (blueline) also includes some unneeded files and doesn’t mention them, and I’ve never used anything but the main image.
