HELP: Need Surface Duo 1 Recovery Image (2023.501.52) – Locked Bootloader / Rollback Index mismatch

[Fozzer007]

Hi everyone, I’m in a critical boot loop on my Surface Duo 1 and need help getting the final recovery image (Build 2023.501.52).

​The Situation:
​State: Bootloader is LOCKED.
​How it happened: Attempted a GSI/Android 15 install which failed. During the process, the device security index (Rollback Index) was bumped to the late 2023 level.

​Current Error: I have the 2022 recovery image, but fastboot boot boot.img returns "Device Error" because the security version is older than the phone's current state.
​Status: getvar all shows Slot A is successful, but it boot loops. Slot B is unbootable..

​The Problem: > The Microsoft Recovery site is rejecting my serial number (and several others I’ve tried), saying the combination is invalid. It seems MS has pulled the legacy links for many Duo 1 units.

​What I need:

Does anyone have a mirror or a working link for the Global/Unlocked 2023.501.52 Recovery ZIP? I need to adb sideload this specific version to satisfy the rollback check and overwrite the corrupted partitions.
​Any help or mirrors (Mega, Drive, etc.) would be greatly appreciated. Thanks!
