Depends, if your phone has a Mediatek SoC this tool worked great for me : https://xdaforums.com/t/backup-full-firmware-rom-of-any-mediatek-device-using-mtk-client-oppo-reno6-5g-mt6877.4406069/
Keep in mind that this is super low level and carries with it a risk of bricking your phone.
Have a snapdragon, thanks for the suggestion!
Qualcomm has a similar tool made by the same person called edl, but it doesn’t work with every phone.
Assuming you are not rooted, you can use adb backup, along with manually backing up your SMS and Call logs, and manually backing up any unsupported apps, like Signal, for example.
Also the userdata partition is encrypted, so a backup of it won’t help much on any encrypted Android phone. You can also backup the envryption key, but I can never remember where that’s stored.
If you are rooted, or if you have an unlocked bootloader and are able to install Magisk, use oandbackup
If you have mediatek SOC, you wont have this issue. They don’t release the source code.
That isn’t an issue anymore really. You can flash GSIs (Generic System Images) if your device supports it and many never MediaTek phones and tablets do. I have done this twice now and it works ok-ish!
