Hi all,
I'm running OOS 4.5.15, unlocked bootloader, still encrypted, xdvs23's TWRP 3.1.1 (build 62 - so quite old) with the latest Magisk. I'm finally ready to upgrade to Oreo and having read some of the threads / guides etc. I think I'm happy to do a full-wipe to upgrade to Oreo and I'm considering going to LineageOS rather than the stock OOS.
As I'm on an old TWRP build that won't work with Oreo, and won't allow me to restore backups I think I need to upgrade to twrp-noapp-3.2.1-0-20180309-codeworkx-cheeseburger.img which will allow me to make a full backup that I could restore later. Once I've got this backup, and a TitaniumBackup I can copy everything off my /sdcard drive to my PC.
I need to lock the bootloader (which will wipe the entire phone) and I can then allow the stock OOS 4.5.15 to upgrade to the latest build of Oreo (5.0.4). I can then unlock the bootloader, re-flash codeworkx TWRP and generally follow the instructions at https://forum.xda-developers.com/oneplus-5/development/rom-lineageos-15-1-oreo-oneplus-5-t3727228 also installing the latest version of Magisk and then restore from TitaniumBackup the apps I actually still want.
Questions:
1) Can my initial twrp backup happen whilst I still have a lock screen pattern / finger print or does this cause issues if I choose to restore later?
2) I see that there are some ~60MB firmware files from https://sourceforge.net/projects/cheeseburgerdumplings/files/15.1/cheeseburger/firmware/ (e.g. firmware_OP5_O2_Open_8_oneplus5.zip) do I need to do anything with these if I'm having OOS upgrade to the latest 5.0.4 (That is Oreo 8.0 but LineageOS is 8.1)? I've not seen any real info on the different firmwares (rather than the OOS changelog).
3) If I want to restore the initial TWRP backup of OOS4.5.15, could I do this after installing LineageOS or is there something else that needs to be done first (as I can't just install Oreo without re-locking the bootloader etc).
4) Is my upgrade process correct, or have I missed something?
Many thanks!
