All you have to do is boot into recovery, nothing else!!! When you go to reboot your phone from recovery options, it will ask you if you want to root. It does it for you just selct yes. It will flash then reboot.
[Samsung Galaxy Light Questions & Answers] killer-kondor:
Soooooo I think I figured out my own problems then..

I downloaded Kies for the PC I am using now. I used Kies to update the firmware on my phone.

Once the firmware updated, I then proceeded to try rebooting in recovery again => found that TWRP had been removed.

So I used download mode and Odin again to push through TWRP.

Then used TWRP to flash the supersu .zip file still on my sd card.

Then I removed the root checker app because it was useless to me. I relaunched SuperSU (since it finally decided to show up) and it said everything was good, i had root access, etc.

Now all I want to do is dump the bloatware that shipped with the phone, courtesy T-Mobile. My ultimate goal is to speed up my phone, because it's been running so slow..

Finally Unbricked My SGH-T399

Hey Gang, remember me? I bricked my SGH-T399 back in march 2014 after installing and using an app that used root and corrupted my EFS partition. This caused my phone to boot loop no matter what I did. I could boot into odin download or recovery and even successfully flash ROM's but they all would boot loop. Well after several months I thought I'd try to fix the phone again. I knew that my EFS partition was corrupt so I thought I'd just recreate it what the heck, No backup, so what. I went into TWRP command line and typed the following:

mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3

Whah La! My phone booted into the LightWave ROM for the SGH-T399 that I tried to install the day before. All along it was the corrupt EFS partition causing a boot loop and preventing a successful boot.

Here's a couple of links that helped me for anyone interested.

I don't have much rooting experience. Ive only rooted 3 or 4 lg motions but they were done with 1 click root appS.

The only time i tried a version that requires a cpu was with the notion before discovering a one click root app. When i tried the usb and separate cpu method i soft bricked my motion even though i followed all directions.

I wanna try to root this galaxy light or its worthless to me so ill try anything.

Root with updated firmware

My rooted Galaxy Light (T-Mobile) was randomly freezing. Specifically, sometimes when I pressed the power button to wake up the phone, the clock in the upper right of the screen had frozen at some earlier time and the phone was unresponsive unless I pressed the power button again until the phone restarted.

For the sake of stability, I wanted to upgrade to Kitkat. I used SuperSu to "unroot" and was able to download the OTA update. I used odin to flash the stock recovery as required by the update. However, at around 25% the update would encounter an error in recovery and rollback the update. Because I do not understand the relationship between rooting, the system partition, bootloader, boot image, recovery partition, kernel, binary, cache, davlik cache, etc, I wiped what I could in cwm recovery, flashed the stock kernel and stock recovery in odin, and performed a factory reset/data wipe. I was able to bring the phone fully up to date using kies. The android version is stilll 4.2.2 (not kitkat), but here is what changed:

Before update:

BASEBAND VERSION: T399UVUAMJ4

KERNEL VERSION: 3.4.39-1611476

SE.INFRA@R0303-06 #1

SUN OCT 6 14:02:43 KST 2013

BUILD #: JDQ39.T399UVUAMJ4

After update:

BASEBAND VERSION:T399UVUANI2

KERNEL VERSION: 3.4.39-2748916

SE.INFRA@SWDA2610 #1

THU SEP 11 19:48:29 KST 2014

BUILD #: JDQ39.T399UVUANI2

My question is can I use the twrp or cwm recovery hosted on shabbypenguin.com to root the phone after the update?

How to Root Samsung Galaxy Light SGH-T399 V. T399UVUANI2 and Keep Stock?

Happy Easter all. I'm currently using a Samsung Galaxy Light SGH-T399 cell phone on version T399UVUANI2. My question is how do I root it?

I previously rooted this device, but I was on an earlier version. When T-Mobile pushed an update, my phone died and I had to send it in for a new phone. Now that I have a new phone, it's updated and I'm not quite sure how to safely root it and keep it as close to stock as possible. Can anyone help?

Samsung is not specifically preventing root access, they're just patching the security bugs. We use those bugs to gain root access, but a malicious app or person could use the same bug to do nasty things.

As for root, we may have to wait for Samsung to release a firmware update. Once they do, it'll be easy to pre-root the ROM before flashing.
[Samsung Galaxy Light Questions & Answers] Classpro:
Good to know. I never understood why manufacturers cared about root access. That makes sense. Let's hope Samsung provides a firmware upgrade soon. They've been slow in announcing plans for kitkat, so I expect more announcements soon. They are getting some real competition from motorola, so they are going to have to act.

Bummer, guess galaxy branding didnt get this phone the clout needed. Low cost tempy to my beloved note 2. Samsung baked Lookout in and I hate, hate nannyware. No way to stop/remove as not listed in appmanager, its eating resources better used on apps I actually want to run. Be great phone, hoping that Samsung does (assuming will with success) that they present same issue with next highend, so we can apply to our phone. Just motivation to save faster. Will continue to monitor thread, but precedence indicates this phone will be tossed in as a "oh works with these models too" for a future model, or with majority of the offbrand, offshoot phones will fade quietly into obscurity. This why always do your research before purchase. Wife picked up for me on a whim, I was actually going to wait out phoneless as work issues BB and I have a 2013 nex7. Not going to lie, I saw galaxy and didnt think root would be an issue, to point I procrastinated 3 weeks.

These are benchmark programs. They tell you how awesome, or not awesome, your phone is. This phone is pretty awesome, guts wise. It just has some garbage that we all are patiently waiting to remove with root.

Chances are really good this will not work due to mismatched components, despite some similar pieces.
