ISTA alternate version programming - weinerbarn - 20-07-2023
ISTA seems to maintain the previous version after upgrades. Example would be latest S18A-23-07-527 while also having alternate S18A-23-03-565. ISTA appears to be able to fallback to a previous version if problems are encountered but is there a way to proactively select the previous version? I read the user guide and could not find any references to this.

release notes are available that instruct in certain vehicles to update to alternative i-level first and then to the latest version.

The release notes give a workaround such as
"Measure/workaround:
Program with alternative I level.
If programming is required at I level 23-03-5xx, contact Technical Support regarding IBAC."
But does not say HOW to program the alternate I level.

ISTA will AUTOMATICALLY choose alternate version for SPECIFIC cars. Online ISTA also asks backend whether alternate version must be used, offline ISTA has only execution break file for that.

So there's no way to manually select the alternate version offline is what I'm hearing? If so, that's fine. Just wanted to make sure I wasn't missing something.

It does automatically when needed. The executionbreak defines when is needed. This is how it works in every version.

I think there's a registry setting you can set.
@Sedoy could you assit?

Answer from __ANGEL__ is right. Use E-Sys for alternative.
