Bootloop problem with Xperia 5ii about newflasher HOT 2 CLOSED

This is not newflasher isue! We can speak on forum, not here. You should try switch to slot A instead of being on slot B as seen in your log, switch to slot A and try reflash. Also read page 72 https://forum.xda-developers.com/t/tool-newflasher-xperia-command-line-flasher.3619426/page-72 there is some info we have discovered recently and I will not repeat it again just read it and try it byself.

Bootloop related to rollback protection:

The gist of the feature is that it’ll prevent your phone from booting if it detects that the device was downgraded to an earlier, now unapproved version of software that has been deemed insecure because of a security vulnerability. A slightly more technical explanation is that the VBMeta data structure, which holds the hash for the boot partition and hashtree metadatas for system and vendor partitions, uses a rollback index to reject images that have an older rollback index.

Thats part of this https://www.xda-developers.com/android-pie-rollback-protection/?_ga=2.172732451.1057106755.1607978449-524393242.1607978449

Don't open another issue since github isues is for real isues only, and since this is not newflasher isue you should continue in forum if you need to ask something

from newflasher.

One who reported #37 issue had boot loop instead of device corupted, and we have discovered (after getting bootloader boot log) that it is rollback protection isue (or maybe fw isue I don't know), but bootloader log clearly states about problem:

load_and_verify_vbmeta:657: ERROR: vbmeta_a: Image rollback index is less than the stored rollback index.

You can open thread on xda xperia 5 II forum and ask somebody. Newflsher apsolutly have nothing to do with it. Even no single error or warning trought newflasher, so no newflasher isue. You should make trim area dump with newflasher (do it excatly after unsucesfull boot) and search for string "load_and_verify_vbmeta" using an text editor, if you see something like this:

load_and_verify_vbmeta:657: ERROR: vbmeta_a: Image rollback index is less than the stored rollback index.

or

load_and_verify_vbmeta:657: ERROR: vbmeta_b: Image rollback index is less than the stored rollback index.

that mean problem is rollback protecion

from newflasher.
