[Samsung Galaxy Watch] amitdon:
ECG Option for R285F with update 4.0.0.8

Finally Its took me lot of hardwork and research ..but finally ECG worked on my watch ....please go through the step step process mentioned below ..and please be sure of taking the risk u if wanna have fun to record ECG ... on LTE watch ...

Pros

LTE worked for Me

Samsung health update for me

The most latest update on LTE R825F watches

Latest firmware LTE .4.0.0.8

Offical update _ no issue of installing the TPK through different sources.

Cons

No Samung pay - which i love the most on watch, anyways will use till I get the official update of 4.0.0.8 on my region.

The process is very similar the way you change the CSC in other watches (R820) but the only difference is the file you use in LTE has to be specific to region .. i was XSA (Australian region) so I updated to LUO (LG plus Region- South Korea).

Check the the link below the following version available on the Fota update to get the latest 4.0.0.8 on R825F.
