I am happy you have success with this update file.
Can you (and anybody with unbrick success), please, write here or to my PM next informations:
1. What is mechanism of your halbrick?
2. What ROM, SPL, unlock state is present on your phone before halfbrick and also the same before update applicating?
3. How you have sent cab file to phone (update cab sender or any coommand line with UpdateWP, full cab or only MODEM subcab)?
4. Have you any certificates problem?
5. Send you it to Mango or after any backup restore?
I am working on full unbrick solution long time. When I will have all informations, I will write Unbrick Manual
