[Galaxy S III Q&A, Help & Troubleshooting] killbubble:
R: just two little small questions about root :)

Actually i would suggest the op also get a cuatom recovery into his phone.

Cuz if he f*** up his phone real bad and doesnt have a pc with him (cuz otherwise you would have to use odin to flash, or odin mobile from phone but if ure phone doesnt work, u cant) he can still fix things thru recovery.

Other things recoveries are for is making NANDROID BACKUPS. basically an almost total backup of your phone data: it backups rom, kernel , apps and their data, modem, system cache a bunch of technical stuff.

It doesnt backup other files of course (such as music on ur phone or videos or documents) just what is necessary to make the phone run with ur apps.

The reason this backup is important is because if you f*** up your phone real bad (again, phone can be tricky to hande:D) you can just flash it clean (you internal phone storage, such as music or any folder which doesnt concern rom, or microsd stuff, wont be touched when you choose "factory reset" in custom recovery)

And restore from a backup when your phone was working. Then u reboot and voila, a trip back into the past!

Might i suggest you also backup the efs folder which is found in the root directory. Nandroids DO NOT cover that. And basically for an s3, if you've got root and internal components are not damaged, if youve got the efs you can fix anything....if ya dont - not so much.

Might suggest once more that IF YOU DONT CARE about all this 'faster roms' kernels and mumbo jumbo root stuff, you still flash a recovery: the most stable one is CWM (clockworkmod recovery). To get it just boot into ur rooted phone, install free app from store "rom manager" and install latest version of recovery. you can boot into phone recovery at ANY GIVEN TIME, just follow instructions u can find on google, pressing buttons at same time and ****.

If ure curious, other recoveries exist:

Clockworkmod touch(premium):it's basically cwm just that it's touch. If you want my point of view...having touch on recovery is stupid and useless...recoveries are for fixin or doing important stuff, you dont wanna mess everything up cuz u touched the screen for mistake. Much better to use buttons and be sure.

Twrp...whatever cant remember da name: same thing as cwm touch, only .......i dunno but cwm is better.

Philz Touch(now this is the real ****!):not stable as cwm. It's a mod of cwm with MANY added cool features such as aroma file browser within the rom and look changing and of course touch( all toucb/double tap touch/touch only for scrolling) but the BEST option is BACKUP COMPRESSION. This little guy made me earn 1gb of free-er space out of my nandroid backups i perform onto my microsd. I went fron 3.5gigs to 2.5gigs. Awesome! Plus you can skip md5 checksum...which is a safety thing of course...but it slows down the backup/restore process, for the most daring disabling it spares them some waiting (nandroids are faster than kies from the pc anyways, no more than 20mins guaranteed!).

If ure interested about kernels i suggest:

Siyah kernel (or syiah...never know which)

Perseus kernel.

They both are good and fast, syiah is more performance, but you can get just the same performance on perseus if you handle the tweaking well and yiu get more battery time.

If youre interested about roms:

Foxhound (most complete one for the s3 i believe, it's packing all you need, and of course it's faster than stock samsung rom)

Rootbox(light rom. Its got less features but still fully packed for speed)

Omega (never tried it. Still have to...but it looks like in this rom look-costumization of look is the easiest thing to do. But i believe foxhound to be fully customizable as well...)

Hope i helped you get some root **** together;)
