ADDITIONAL INFORMATION

If I understood correctly, "twrp-3.5.0_9-0-jflte" should work since the partition structure is not of type "Android-10" since the official version has stopped at " Android-5 "... but maybe I didn't understand a thing. If this is because it would require a "twrp-3.5.0_10-0-jflte" version, are there any plans to make one? It would be a shame if a good device which is followed by "LineageOS" in "android-10" version stops at "Android-9" for lack of saving in TWRP ... but I am very aware that it is easy to to ask and (much) more difficult to do. Excuse me

--- 21/3/21 --- Since version 3.5.1, the backup works perfectly. Thank you very much. On the other hand, the encryption of the device does not work: I put a "post" at LineageOS ---
