Infinix X690B-Factory Signed Firmware H691DE-Q-GL-210930V341 By[]


Factory Signed Firmware:

Factory Signed Firmware in popular mobile phone brands like Tecno, Infinix, Itel, etc..
Factory Signed Firmware (FSF) as a means of restructuring the GSM Market
(which has been killed by road-side technicians). As you all can see,
most firmware websites which uploads factory signed firmware for downloads,
sell this firmware as it is also purchased from Calcare centers or directly
from the Mobile phone’s brand Service centers



As a Mobile Phone Technician, you all know what a Backup (Dump) Firmware is and How
The components it contains. Without writing much, below is an attachment (a screenshot)
showing the full component of a Backup (Dump) Firmware and a Factory Signed Firmware.


Factory Signed Firmware Fixed:

Another good difference between this two firmware is that the Factory Signed Firmware is
the perfect firmware you should flash to any secure boot device. It helps you fix 100% software issues like:

Boot loop (Hang on Boot Logo)
Google Account Factory Reset Protection (FRP)
Support API 3 (Supported: API 3)
Unknown Baseband
Privacy Protection
Ghost-push Virus

While flashing a dumped firmware to a secure boot device is 50%
out of 100% which if unsuccessful, you may end up having a ‘bricked’ or ‘dead’ device.
