One advice :
When you are not sure do not advice others.

@bandrei2501
you may kill some M55 v11 with freia so better do not try to downgrade.

i have d/grade M55v11 to v10 w/o testpoint.
simply upload fullflash v4 or v7, and then v10.

i downgraded from v11 to unofficial v10 using wsup, and then you can upgrade to official v10 as normal...

what r u talking about? why r u dwlnoading him?
