*facepalm* Revert back to Android 2.3.3 or 2.3.4 version,then root your phone (but you'll stay in Gingerbread firmware since ICS can't be root directly)
If you still wanna have root in ICS,check carefully in your phone forum section

Locked bootloader (unlock allowed yes) - You can't flash custom kernel or custom Rom that aren't base of stock Rom,but you can unlock it
Locked bootloader (unlock allowed no) - Same as above,but you can't unlock it for other reason (eg.contract phone by at&t,so they lock it permanently)
Unlocked bootloader (unlock allowed yes) - You can flash custom kernel and custom Rom that are not base on stock Rom (yay!),but you lost DRM key and can't use some application like TrackID...unlocked using Official Sony website
Unlock bootloader (unlocked allowed no) - Same as above,but it's not actually 'unlocked',but it's a patched version of bootloader which it still have DRM,but still can be flash custom kernel or Rom...unlocked using TestPoint usually

So I have to unlock boot loader to root my phone?
Or I can flash custom ROM only by unlocking boot loader or root is needed?

No no no,you doesn't have to unlock bootloader to root,and you can ACTUALLY flash custom Rom on your phone with a locked bootloader that are BASED ON STOCK ROM....but I would recommended to unlock bootloader as custom Rom wil usually ask for a custom kernel...

Have you unlocked it? When you rooted, what process did you use? Since you said you're running JB on a Verizon SGS3, I would put money on your bootloader already being unlocked...

Flash rom without root?

Is it possible to flash a custom rom without root? If so, where can I find one?
Thanks for your help!
Sent from my SCH-I535 using xda app-developers app
No. No custom roms unless you're rooted and unlocked. The closest you'll get are flashing Verizon factory stock roms via Odin, but those are not rooted.

What is your purpose to use custom rom without root?? Custom rom, by default required root for all the modded apps to work.

Umm, why?
I'm new and just trying to learn, that's all. I come from I phone. The S3 un-rooted can already do more than a jailbroken iphone. Almost like learning a new language with the Android and rooting.

As far as i know, all custom roms require the device to be rooted, firts of all you need to root/unlock your phone, then install Recovery Application that would help you flash custom rom (Like ClockWordMod) and after that flash your custom rom.
Btw all that info is located on this forum for each and any Android phone regardless of brand and model (at least 90% of them).

Yes you have to root your phone to root your phone you need to unlock bootloader than install recovery then you can install a custom ROM... You will find procedure in your device foram hopefully...
And rooting means to get Administrator privileges... I hope it helped.

If you are using cwm recovery it means your bootloader is already unlocked just put your desired rom zip file in sd card and then make a nandroid backup of your current rom.. You can make nandroid backup by going in cwm recovery and select backup and restore and follow the procedure..
After this do a factory reset and then install your rom....
I hope it helped.?
