Hi Piero,
It worked, but… Let me guide you through my mistake…
Thank you for your time and for shedding some light on my problem. So, as I don’t need any firmware and the old recovery-e I have (v. 3.0.4) should work, I shouldn’t run into any issues. However:
- Universal Method, download the file on a computer, boot the phone into the recovery mode and use “apply update” then “from ADB”
Works fine, when you have the right build^^ I trieds to install the one for gts4lv and not the right one for gts4lvwifi…
So, now it’s fine, everything works !
Thanks for your patience.
