I’m finally about to do it… upgrading from a Samsung S2 Android (had it 7 long years) to an S3 LTE that I will flash with /e/. I need to know; is it best to upgrade the firmware of the ‘new’ S3 before installing /e/? If so, how do I go about that? I’d generally prefer not to link to Play as I’ve managed so far (hence the S2 is 7 years without an update and I have no experience of doing it). If I must attach to Play, then so be it.
I’m an utter noob and I know I can potentially brick the S3, but I’m going for it. Never flashed anything before, except for pwning an ancient iPhone that I had before the S2.
Android Version 4.3
Finding & download the latest Samsung firmware Android 4.4.4 Kitkat of your Country for the Galaxy S III (LTE / Int.) “i9305” has now become particularly easy with the new version of the tool → SamFirm 0.4.1.
Thanks for the answers, @archie and @Anonyme … I wish I had sent this last night as most answers are tailored towards Windows. Fortunately, I’m a Linux using noob so I started following the instructions Archie suggested.
I got stuck at the first instruction (Enable OEM Unlock), and discovered elsewhere that there is no ‘OEM Unlock’ option before Android 5.0 (Loillipop). What to do?
I have tried updating the S3 over wifi but it states that the latest updates are already installed. I understand that 4.4 KitKat is possible for the i9305 but my phone doesn’t want to get it for some reason (perhaps terminated support on such an elderly device?).
I looked up SamFirm (to look for a Linux equivalent) and a post at XDA-Dev suggest that it is deprecated and suggest Updato.com
The rabbit hole deepens… perhaps you’d be kind enough to revise your kind advice for Linux use? Do you consider Updato safe?
This whole thing is quite labyrinthine! I would never have suspected that it would be applied differently in different countries.
United Kingdom, Russia, Singapore, Hong Kong, UAE and Kuwait; an axis of deprecation!
