Question Got a buncha questions for you guys

Hello, my roommate has a Verizon Galaxy S3. He recently took the 4.4 update, and it apparently screwed up his phone pretty bad. He gets terrible battery life and force closes and freezing. He came into my room knowing that I'm an android nerd and he asked me to root and rom his phone. Cool.

So, now I'm trying to catch up on the current state of the GS3.

He has never rooted or installed recovery. I was under the impression that the Verizon GS3 had an unlocked bootloader, but now I'm reading that the bootloader might be locked since he updated?

1: Is it possible to ODIN back to an earlier version and then unlock his bootloader?

2: What's JTAG?

3: Is there an easy way to install recovery on 4.4 that I'm missing?


Any links or advice you guys could give me would be really helpful... I'm currently reading and jumping between links, but It's hard to figure out where the phone currently stands with all the conflicting information out there and the new update that just pushed.

1: No, it is not possible to ODIN back to unlock the bootloader. Your friend is stuck on 4.4.2.

2: JTAG is a service you can send your phone off for and pay for to unbrick a hard bricked phone. As long as you or your friend do not hard brick his phone, you won't need a JTAG.

3: You cannot install any kind of standard recovery on 4.3.1 or 4.4.2 on the Verizon Galaxy S3. There is an unofficial safestrap you may be able to use on 4.4.2 found here -> http://forum.xda-developers.com/show....php?t=2797314 But there are no ROMs to flash using safestrap, so for the moment it is kind of pointless.

There really isn't conflicting information in these threads unless you are looking at old, outdated threads on rooting. All of the information anyone needs to know about the current state of the Verizon Galaxy S3 can be found in just a few threads:

Shouldn't we treat this world like the garden of Eden and avoid the apple at all costs?
