You might want to try either DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_003-OEM1-958 or DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_005-OEM1-958 or DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_006-OEM1-958 from the first post.
One of then should work, depending of your variant (001, 003, 005, 006) guessing yours is higher than variant 001 as that didnt work.

It IS possible to downgrade. By replacing the certs, as the device does have a history of previously versions. But, success depends on whats on the ‘cache’ (simple said), and replacing those certs is not that easy. I did it once , but honestly, cant remember the complete steps. The tools needed and a rough deskription is in another thread somewhere on downgrading.

So, try different variants first. Just not China ones
