Most importantly, I don't understand the right steps.
First I made the manual:
FASTBOOT
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash vbmeta vbmeta.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash oem oem _ *. img (Tama (latest) -> https://developer.sony.com/file/down...rnel-4-9-tama/
(Optional, but mandatory on first boot) fastboot flash userdata userdata.img -> will factory reset the device.
After:
TWRP
(Mandatory on dual sim devices) Dual Sim Patcher
(Optional) https://opengapps.org/ or MicroG
Here, I don't know how I should do:
- Should I flash Apollo_v8?
- Should I flash fastboot flash boot boot.img and fastboot flash vendor vendor.img from Testbuild folder?
- Should I flash other things?
(SORRY, I always VMETA)

I have tried a multitude of options, with Twrp_v8, with boot and vendor, and bootloop, and with different twrp that do not work the touch and I can not continue ...
I strongly urge you to indicate the steps please.
Thank you.

I updated the instructions in the OmniROM 9 and TWRP 9 threads

Instead of a backup, what could be the risk if I only boot to the image (and not flash it) to see if everything goes well ?

Yes, at the moment compiled for the XZ2 on my local machine to test in my next free time.

Migrate and Titanium only backup your apps, so you can restore them on every phone/rom.

About the customizations -> Google backup did backup some at my side, but make sure you don't make a new google backup on a different rom.

I don't know which issues may occur if you don't wipe your userdata.
Switching between ROMs/android versions may cause issues.

How to deactivate vbmeta is written on the twrp/omnirom/sonyaosp thread on the first page

Hi
I think I've done it, with Boot + vendor of Apollo V10 and then TWRPv8.
Thank you very very much.

Thanks for your anwser

Ok, that would be great, AOSP is a bit… basic ^^

Apps and their content I guess ? (such as message history and so on)
Including system settings ?
After a wipe, will I have to root my phone again ?

Is there a way to do a full backup (including the system ?) just in case something goes wrong and I want to restore it ? (in its initial state before migrating)

I'm not using Google backup (or any Google stuff) so no issue here.


Switching may cause issue, only if I flash it or even with a simple boot ?

Yes, unless they contain a security feature avoiding backups from 3rd party apps

No and yes, you need to root again

You could try a nandroid backup to backup your entire phone image

Simple boot would not work, different kernels/dtbo partitions
And just booting only contains the kernel, not the rom.

You're welcome.

Yes. But for example not manually created folder at the homescreen. That can only do a twrp with 1:1 backup of the data partition.

Not when you only backup user apps with Titanium Backup. There is a action called 'backup all system data' but i never test this.

If you want to install this rom and were on another rom before yes because it comes with his own boot img.
In general: Everytime when you replace the current boot.img against a new one Magisk must be installed new because Magisk lives in the patched boot img.

Yes over twrp (when you backuped all partitions before)

Well a dirty flash can lead to problems. A clean flash is always the better way.

About the next ROM which acts as a successor for the OmniROM here


(Still work in progress, it is usable like my SODP 10.0 release here, but I need to clean up my entire build environment, optimize it and add xz3/xz2c and while we don't have a twrp for the dualsim patcher [comes later, I promise] I need to build dual sim versions, too).
