UPDATE!!!!!!​

Video Guide for Installing and Using Safestrap by Face_Plant

Installing Safestrap v3.72 by Face_Plant:good:

1. Download and install Busybox from the Play Store.

2. Download and install Safestrap v3.72

3. Open Safestrap and click on "install recovery"

4. Reboot and you should see a screen with a robot thing on it. Press the button on the lower left of the screen to boot into Safestrap

5. Make a backup of your stock ROM

6. Go to wipe and do a factory reset

7. Go to install and select the ROM you wish to install

8. Reboot after it's done installing

Tips:

1. I recommend saving all backups to your external SD card in case you accidentally wipe your internal storage

2. NEVER USE THE FORMAT DATA FEATURE!!! This will completely wipeout the stock slot on your phone and brick it. You will not be able to boot into Safestrap to recover (ask me how I know....)

You can use the ROM slots, but the reboot menu will not work. You have to pull the battery to shut it down. You will also get notifications that you're running out of storage. I looked at the storage info in settings after getting this notification and it said ~25 gigs were required to run the ROM as opposed to the 6GB or so that's normally required.

**************************************************************************************************************************************************************************************​

ROOT FIX !!

Install N900AATTCNC2_KERNEL.tar.md5 Kernel (3.4.0-722276) with Odin then

Towel Root will work TR.apk

Odin Install

Verify Kernel Install

Verify Root Root Checker

Now You can Install SafeStrap 3.7.2 and install any custom ROM YOU NEED BUSYBOX FOR SAFESTRAP to WORK

Do a factory reset from Safestrap

FAST!! QUICK LINK--MediaFire---------------------------------------------------------------->>>>>> sec_csc.zip Install with Stock Recovery MD5 Number B40994F984EEE97D5428E4EE96504A2F

First Copy sec_csc.zip to your external SD-Card ( you have to get one if you do not have one)

Then install with ODIN the 4 files from NC2_Bootloader_Odin3_Install_N900AUCECMGL.zip

Make Sure Your ODIN Looks Like the Picture here

After Odin reboots your phone, Immediately Hold Down POWER + MENU + VOLUME UP BUTTON and get into recovery and install sec_csc.zip

You Cannot Use this Copy of MGL KitKat to down-grade to 4.3

Once You Updated to NC2 KitKat Your stuck cannot go back, your are burn to fuse 3

The Only thing changed in the BL_N900AUCECMGL.tar

is the [aboot] file

from the OTA NC2 Update. So this is not a FULL NC2 Firmware

I used sgs2toext4 (created by drphrozen ) to convert cache.img.ext4 to cache.img.ext4.img

then used ext2explore to unpack cache.img.ext4.img

UnPacked You find the sec_csc.zip and command files in it.

command file did this with original Install :

--update_package=CACHE:recovery/sec_csc.zip

--carry_out=csc_factory

--wipe_data

unzipping sec_csc.zip we find security files and AT&T setup

Updater script in META-INF Folder

show_progress(0.100000, 0);

show_progress(0.500000, 0);

package_extract_dir("system", "/system");

But we have to do it manually with stock recovery
