ZV5 Update doesn't allow rolback

[FluffyMittens]

Just a heads up for everyone developing, ZV5 doesn't allow rollback and there isnt a zv5 tot available yet. So probably not a good idea to update until we get root.

And what is your base for this?

There's apparently a flag set in the new firmware that prevents rolling back.
It was discovered while attempting to test a root method that involved a modified ZV4-based image, on a phone that was updated to zv5.

This explains a bit.

I highly doubt this is the case, and it's something we can't do right now with the limited tools we have.

Nothing out of the ordinary, the G4 LS991 was the same way - had Anti-Rollback after LS991 ZVA version.

Just as a note, i have tried using the 'Send_Command' trick @ 9% with LGUP on the G5 like we did on the G4 (see my sig), but something has been patched and now entering anything at the root prompt, says 'Hello, I am LAF nice to meet you!'. This means no DD commands will work to pull the system image, modify then put back like we did on G4.

We will have to wait for another trick.
