ver5.135.. I think its the latest one.. by the way today I formatted successfully as shown in your ss and downloaded full backup again but no call-proximity restored. calibration also not working.
Something new.. after format and download I got no-network and imei-null. again I restored nvram backup with mtk tool and imei/network came back.
anyways.. thanks for your concern. everything else in phone is working normal.
1. spft u r using is on desktop/main drive (c)?
2. Gave admin previleges to spft?
3. Disable uac and anti virus before using spft...btw which version of Windows r u using?
4. Tried firmware upgrade instead of download?
5. Tried meta mode?
6. Try on lower version of spft...e.g. v3...
