Thank you,
I was on Habib 4.7 and wanted to downgrade
used habib 999 downgrader (spoofed 4.46 ) showed as 4.46 in system information,
couldnt load anything other cfw without 8002f157 error, QA toggle made no difference.
Recovery menu showed version as 9.999 and Rebug 3.55v7 worked OK from the recovery console
Found this thread and now I am working again
Cheers.
