The LG G5 F700S firmware is no longer on our server since we had to reduce our server expenses recently.
Some smartphone manufacturers have free firmware update tools that are capable of downloading firmware files directly from the manufacturer’s servers. Check GitHub or XDA Developers to see if one of the free firmware update tools is available for LG smartphones.
We also have several reliable competitors who tend to share the same files as us. However, we do not know any of our competitors personally so we cannot recommend anyone personally.
There is also a chance LG may share the firmware file with you if you ask them. However, they typically prefer you send the smartphone to them and they will flash it themselves.
