Need help! Cant get back to kk base roms

I have been on this D801 TMO LP Extreme v1.0 rom since may. I like the rom its really nice but i want to go back to a kk rom. So ii download the 20g boostack and the OptimusG3 Rom V1.4.1 rom. First i wiped....flashed firmware..then flashed optimus rom...o wss stuck in bootloop. Then i flashed the firmwear...wiped...and flashed optimus rom. At the end of that flash it says something about loki failed or something like that and i was stuck in bootloop again. So i ended up flashing 30b bootstack and extreme rom again...how do i go back to kk? Can i get some help here? What am i doing wrong?

[TUT] How to root G900F with OE5 base

Hello everyone!

I am making this thread to explain how to achieve ROOT on G900F devices with "the famous May update" aka Base OE5.

DO NOT USE ON OTHER DEVICES THAN G900F (THE F MODEL, QUALCOMM 4G EUROPEAN DEVICE).
I AM NOT RESPONSIBLE FOR ANY DAMAGE TO YOUR PHONE, DATA, LOSS OF JOB BECAUSE OF FAILED ALARM APP AND SO ON!
YOUR WARRANTY IS NOW VOID AND YOUR KNOX COUNTER IS 0x1 FOREVER!

Many users are having issues getting it rooted and even I was trying many methods to root it and always ended up with bricked phone and corrupt data.

1) Back the hell up your device, this is extremely important as sometimes your data partition and apps will get corrupt. SmartSwitch is great tool for backing up made by Samsung.
* Disable reactivation lock in settings (I also disabled lockscreen fingerprints and account fingerprints just to be safe)
* Unlock Developer options by goint to About phone and dapping Build number 7 times.
* In Developer options turn on USB Debugging.
* Download latest SuperSU zip and put it in your phones storage (mandatory) - https://download.chainfire.eu/693/Su...erSU-v2.44.zip
2) Go to https://dl.twrp.me/klte/ and download THE LATEST recovery - twrp-2.8.7.0-klte.img.tar (11.9MB in size). DO NOT EXTRACT IT AND MAKE SURE IT IS TAR FILE NOT IMG FILE!
3) Download ODIN 3.10.6 from trusted source, like this one - http://odin3.en.lo4d.com/download and extract it to desktop.
4) Start ODIN with admin rights, in AP section select downloaded recovery TAR file and make sure to un-check the AUTO REBOOT option (it will be in different tab in this new looking ODIN, look for it carefuly).
5) Reboot your phone in Download mode by holding VOLUME DOWN, HOME and POWER keys, press VOLUME UP when prompted to.
6) Connect your phone to computer and wait for drivers to be installed or install them manually. USE ORIGINAL USB CABLE.
7) When ODIN shows that your device is added, click START and wait untill it shows PASS.
8) When PASSed, hold VOLUME UP, HOME and POWER keys until it reboots to recovery and TWRP splash screen should appear.
9) When recovery booted, make a full backup of all partitions. (THIS IS EXTREMELY IMPORTANT)
10) Now choose INSTALL option and find the SuperSU package you put in the storage at sub-steps previously. Install it.
11) When zip with SuperSU is installed, click WIPE CACHE, DALVIK and confirm (MANDATORY, MAY CAUSE PROBLEMS WITHOUT)
12) Reboot your phone, wait for Android to optimise your apps and check ROOT status.
13) Start modding your phone and please hit the thansk button and report back if this method worked.

Stagefright Vulnerability Fix - Note 3 Stock base ROM

Overview

Stagefright is the media playback service for Android, introduced in Android 2.2 (Froyo). Stagefright in versions of Android prior to 5.1.1_r9 may contain multiple vulnerabilities, including several integer overflows, which may allow a remote attacker to execute code on the device.

Description

According to a Zimperium zLabs blog post, Android's Stagefright engine contains multiple vulnerabilities, including several integer overflows, allowing a remote attacker to access files or possibly execute code on the device. This vulnerability may at least partially affect all versions of Android starting from 2.2 (Froyo) and prior to 5.1.1_r9 (Lollipop).
An attacker with a victim's cell phone number may send maliciously crafted multimedia messages (MMS) which may be improperly parsed by the Stagefright tool. Other attack vectors may be possible.
According to Ars Technica, "successful exploits at the very least provide direct access to a phone's audio and camera feeds and to the external storage ... many older phones grant elevated system privileges to Stagefright code, a design that could allow attackers access to many more device resources."
Zimperium has released more information on these vulnerabilities, including a proof of concept code, patches, a video demoing the exploit and an Android app that detects the vulnerability.


The vulnerabilities include:

Code:

---

1.        CVE-2015-1538, P0006, Google Stagefright ‘stsc’ MP4 Atom Integer Overflow Remote Code Execution
2.        CVE-2015-1538, P0004, Google Stagefright ‘ctts’ MP4 Atom Integer Overflow Remote Code Execution
3.        CVE-2015-1538, P0004, Google Stagefright ‘stts’ MP4 Atom Integer Overflow Remote Code Execution
4.        CVE-2015-1538, P0004, Google Stagefright ‘stss’ MP4 Atom Integer Overflow Remote Code Execution
5.        CVE-2015-1539, P0007, Google Stagefright ‘esds’ MP4 Atom Integer Underflow Remote Code Execution
6.        CVE-2015-3827, P0008, Google Stagefright ‘covr’ MP4 Atom Integer Underflow Remote Code Execution
7.        CVE-2015-3826, P0009, Google Stagefright 3GPP Metadata Buffer Overread
8.        CVE-2015-3828, P0010, Google Stagefright 3GPP Integer Underflow Remote Code Execution
9.        CVE-2015-3824, P0011, Google Stagefright ‘tx3g’ MP4 Atom Integer Overflow Remote Code Execution
10.        CVE-2015-3829, P0012, Google Stagefright ‘covr’ MP4 Atom Integer Overflow Remote Code Execution

---

Since integer overflow is a type of memory error, Address Space Layout Randomization (ASLR) appears to partially mitigate this issue; Forbes reports that Android before 4.1 (Jelly Bean) have "inadequate exploit mitigations." ASLR was introduced in Android 4.0 and fully enabled in Android 4.1.

Impact
A remote attacker may be able to execute code on the Android device.
