[Q] Can I re-root?

After almost two years, things have become much more confusing for me as to if I can re-root after having had to do a restore to factory.
Here's what I have under About Device
Code:
SPH-L720
Software version: L720VPUFNG2
Hardware version:L720.08
Model Number: SPH-L720
Android version: 4.4.2
Baseband version: L720VPUFNG2
Kernel version:

Build number: KOT49H.L720VPUFNG2
SE for Android Status:
-Enforcing
-SEPF_SPH-L720_4.4.2_0018
-Wed Jul 09 09:03:50 2014
Secure boot status: Type: Samsung
Security software version: MDF v1.0 Release 2
Here's what I see when in Download Mode
Code:
current binary: samsung official
system status: official
knox kernel lock: 0x0
knox warranty void: 0x0
csb-config-lsb: 0x30
write protection: enabled
emmc burst mode enable
I ask because I can't seem to find the right combination of variables for my situation. I can find root methods for 4.4.2, but not with NG2, or I can find root methods for NG2, but not with 4.4.2, and then this whole KNOX thing is totally new to me. At this point, I don't care about putting CM12 back on, I just want a stock OS with root access so I can tweak things here and there asI see fit.

NG2 is 4.4.2, all you need to do is flash a custom recovery through Odin (I recommend TWRP in Original Development). Then flash Chainfire's SuperSU.zip , update your bookmarks when the phone reboots and done. Knox simply prevents you from downgrading your firmware.

Thank you, I really appreciate the help. I've gotten a bit out of touch with the rooting scene and just wasn't sure what was safe and wasn't safe.

[Q] Hardware revisions and machine versions poll

Hi all,
in preparation for my kernel in some future time, I wonder what hardware revisions and machine versions are out in the market.
So if anyone knowing how to look into a dmesg log could just post what he has, it would help me to figure out more insight about the device trees used (and which ones are obsolete).
Below is how my dmesg log straigt after start looks like, I made the interesting sections in bold and red.
If you want to contribute, do the following (you must be rooted):
- restart your phone
- open terminal window and do the following commands (enter after every one)
su
dmesg > /sdcard/klog.txt
- inspect the klog.txt file with a text editor from the beginning for the information I have marked in bold.
Thanks for your help

Thanks guys.
Interesting results so far, only one hw revision and machine version.
Let's see when the first different specs come up

Here's mine

So far looks like there is only one combo out in the market, interesting...

Hi lord bofella.. I love your work on oneplus one... Just wanted to ask.. In future with the development... is it possible to control the 810 heating and throttling with custom kernels and make oneplus 2 a better phone

We will see. But in normal usage (and I do not play games etc.) I never faced any heating issues which I really "felt".

hi andi, same here: Machine: Qualcomm Technologies, Inc. MSM8994v2.1 MTP
no jokes today, my wife says they are at times not easy to understand hahah....
rooted up and running BTW, keep stock for the time being with a few tweaks and mods of course but still, no decent rom around yet.
running well, i like it
if you need a second device for development again later on, let me know so that we can make it happen for you like last time
thanks in advance for "you know what i mean"

I'm wondering if there's going to be a way to open up all basebands in the future. I efed up and ordered a Chinese version in the us so I'll be without lte. If it's all the same hardware surely there is a way to open up the band's I need

It's fake Android 10.. API 27 is Android 8.1
Use an app called "Device Info" this will give you more info.

Short answer is no. Your MCU isn't compatible neither your Android type.

With the usb connected and flash tool in Write Memory with ROM_2 selected in EMMC_USER, i played around with red wire and usb while shorting test point writing started but got an error at 4% and powering up brought Android logo in my dead HU. Then flashed full firmware without preloader and it was back to normal. Trying to root bricked it again.
Same issues as earlier, 4032 without shorting tp and EMMC NAND error upon shorting tp.
