I tried to go on Rebug 3.55.4 but it wont work :/
Hi,
I'm hoping you disabled your Q.A first via RebugToolBox and so if still on DEX firmware always use DEX-3.55 downgrader or it will give you an error.
Side note: once your back on 3.55 reinstall Q.A and activate it and go to debug setting and enable "system update".
I hope that helps. goodluck
