No - eRecovery is working only for Chinese Models.Can I use the eRecovery method if I am on V3 of MagicRainbow?
In MRv3 Thread is in Post 3 or 4 (just look) a description how to go back to Stock.
Your question is off topic here, why you don't ask in MRv3 Thread?
You can also use the Rebrand Tool HWOTA7 for EVA (with "Change Firmware" and the right Firmware in the update folder) for going back to Stock.
