Hello
Hello
Sauvegarde "Nandroid"
It is precisely the use of TWRP that I took to back up my old LG or Samsung devices (S7, EDG or Tab 4 tablet)
Before the appearance of "dynamic partitions", there were no questions to ask to make a "Nandroid Backup" of your smartphone.
Now, since the arrival of OOS 10 and 11, things are different.
So here is my question for you:
If I check all the boxes by doing the backup and restore with TWRP (version 3.6.0), will the smartphone return to its general and precise state at the time of the backup? (See attached screenshots from TWRP)
If I understood correctly, TWRP performs a global image (super partition including A and B ) of all partitions at the time of backup, similar to an image of an SSD or HDD with several partitions… That's good that ?
I thank you in advance for your information and explanations and your instructions so that I can perform a "Nandroid Backup" and a possible restoration in complete safety.
Best regards
Jean-Noel
