[Galaxy S III Original Android Development] Hatimu:
Hi there. I've had Philz Recovery (philz_touch_6.48.4-i9300.zip.md5 to be exact)running on my I9300 for quite some time now. It was the first (and also only) custom recovery I flashed via Odin back then in 2014 when I first moved over from Stock JB 4.3. I was always satisfied with the recovery itself - it always did its job nicely. I don't recall ever having any problems with it whatsoever. However...I have to admit that I've never actually used GPS on my I9300 over the past few years (not on Stock JB 4.3. nor afterwards while flashing the various custom roms). In the end I settled down with the Resurrection Remix ROM, which was by far the best custom rom for my taste and offered me more I could have hoped for in a rom. So there I was flashing all the lollipop based RR rom updates, and obviously continued the same procedure with their latest Android Marshmallow beta development. But again - I never actually used GPS on my phone while doing that. So today when I was going through all of my backups (all the way back to Cyanogenmod Kitkat 4.4) I actually realized that I never had a properly working GPS signal on my phone :confused: And since I just recently bought Sygic Premium cause I'll need a working GPS system in my car starting this February, I was now thinking of doing the following:

Download the "latest" Stock JB 4.3 firmware from SamMobile & Flash it via Odin;

Flash TWRP via Odin;

Flash custom rom (Resurrection Remix in my case) via TWRP;

Flash Gapps;

So here come's the part where I'm a bit confused still., and would again require your help & quidance:

When checking out twrp's official download page here I realized that the latest *.tar file that I would be needing is actually twrp-2.8.6.1-i9300.tar. But since the custom rom that I plan on flashing (after flashing stock JB again that is ofc) recommends flashing the rom using twrp-2.8.7.x+...I'd like to know if I would be ok flashing the twrp-2.8.7.3-i9300.tar file that got uploaded here a couple of post back by [MENTION=6155853]rpdroky[/MENTION]? Is this really the "official" twrp release and is working 100%, or am I better of flashing an older version?

Just out of curiosity: if I were to flash twrp-2.8.6.1-i9300.tar via Odin first, are there ways of updating the same recovery later on via the recovery itself (and if so, how does one accomplish that?);

Also...would I need to root my device via Odin after flashing the Stock JB 4.3 again & before flashing the correct twrp.tar file via Odin, or should I be fine with flashing the twrp.tar file dirrectly after flashing the Stock JB 4.3 onto my device via Odin?

I know it's a rather long post, but since I'm new to twrp, I really want to make everything right :) I decided to move over from Philz Recovery to TWRP mainly due to 2 reasons: one being that I actually have no "good" backup in Philz Recovery so I wouldn't be missing anything, and the second one being the fact that PR hasn't been updated in a very long time - where TWRP keeps its updating process up and running still by today. Ow...and twrp is also highly recommended by the custom rom developer :angel:

Btw: I've already tried using various apps (like GPS locker etc.) to get a proper GPS signal working and switching between various backups, but nothing seems to work. So I'm assuming a "fresh" start is my only option left?

Thank you in advance!
