WiFi Calling S7 Edge and Firmware

[Anonymous]

I am not happy!  TuGo never worked properly for me and now to get my S7 Edge working on WiFi calling I have to take O2 firmware and apparantly this requires a trip to a shop. Does anyone have experience of this?

1. What danger is there to the phone/contents?

2. Do they do this in front of you? ...nobody is taking my unlocked phone away from my view 🙂

3. Is it reversible? (...'cos after my experience I am moving away ASAP .. in March)

4. Do O2 update firmware immediatly after Samsung release, especially for security patches?

Thanks ..Phil

O2 won’t flash your firmware in store.
The only way they may do it is by sending it off to their repairs team, but I’m not aware that is something they offer for free or even at all.

Thanks. Much appreciated .. their online chat told me yesterday that it could be done in store .... not convinced though!

The patch speed is also a concern.

At this rate I will be buying out of O2 and finding someone else!

If you use a certain search engine to search for information on flashing you may come across information that will allow you to do this yourself (at your own risk). NB: we're not allowed to pass over instructions on how to do this. However to answer you questions

(1) There is a risk you phone can be bricked (non responsive) but this is low risk from experience

(2) O2 will not do this for you, at best they will send it off to be done

(3) It is reversable using the same methods (however O2 will not do this step since you're asking them to take off their software)

(4) No, most networks take some time to varify the contents and test the updates before they will release this to you.

I guess I can't do it myself since they took your guide down!

Reversing any changes which result in downgrading to an older level of firmware will trip the Knox fuse and void the warranty immediately.

Sorry .. crossed.

Many thanks.

@MI5 depends what you do here, usually O2 firmware is behind the generic version (or the same) so changing between generic and branded on the same version shouldn't effect it

I know that but anyone who doesn't know what they are doing wouldn't.
You can't just go flashing firmware risk free.
