[Help] Fix Secure Boot Error - G2 Q&A, Help & Troubleshooting

Hello,
today I wanted to install cm on my LG G2 D802 (international version, Germany) with 16GB
I updated kitkat to the latest version via OTA:
Android Version: 4.4.2
Buildnummer: KOT49I.D80220d
Software Version: D80200d-262-02
I rooted the phone with the latest ioroot tool from xda
After that I tried AutoRec to install TWRP but I was stuck at "Checking for loki... installing"
Then I flashed TWRP (2.7 and 2.6.3) with the APP flashify.
Now everytime I try to boot into recovery I get the error:
Secure Booting Error
I can normaly boot up the device and only the recovery is broken.
What can I do to install TWRP?
Or how do I revert the current recovery to a stock recovery?
Thanks

[Q] Got a used D800..

Should I flash the latest KK image to ensure the modem and bootloader are latest version..
The baseband says: M8974A-AAAANAZM-1.0.190082
I received it with 2.7.0.0 twrp and there were custom rom zips all over.. so I can not tell when it was rooted..
Open to suggestions..
Hey mystique
If you want to start with a clean slate I recommend getting your stock image from here
And use the lg flashtool in the back to stock guide to flash it.
Incidently, since your on twrp 2.7 I assume that you're on the jb boot loader
What was that "phone info tool" to find the bootloader version..
Looks like the device was initially rooted in July 2014..
Assuming that they had kk and such..

D802 problems with installing custom rom, custom recovery and root.

Model is d802 16gb. Changed back to stok with Flash Tool 2014 with 20D open soft. Show that are rooted. First installed Philz Touch last version but can´t install custom rom RessurectionRemix last version, give error. Now lade new clean stock rom and rooted ioroot again and now installed Flashifly, then attempted to install from that way cwm and Philz but got on reboot get "secure reboot error" and black screen. With power button can turn of when hold down long and phone boot normal but cant enter to recovery anymore.
Did it again with fresh mind and works fine. What I did: new 20d kdz with LG FlashTool 2014, rooted with ioroot25, installed AutoRec, in AutoRec installed PhilzTouch 6.41.4, installed custom rom. What I missed before: in custom recovery install I did´nt used AutoRec, in custom rom installation did´nt system whipe/factory reset( I used Clean for new rom). All works 100% now.

G530H TWRP Recovery Installing issue

Hello.
So I just downloaded the TWRP, and flashed it into my phone using Odin.
What's the problem is, odin flashed twrp successfully into my phone with PASS message. and my phone restarted. Then when i tried to launch it into the recovery mode, using vol up+power+home, there's no changes in the recovery mode. No TWRP recovery, my phone still using the stock recovery.
Tried to flash philz recovery with "Set warranty bit: recovery" error, neither flashed the mohan root and still got the same error.
Any help with the problem? Thank You for any further helps.
Currently using Android 5.0.2 with G530HXCU1BPE4 Firmware (https://samsung-firmware.org/downlo...al Sim)/27O0/SER/G530HXCU1BPE4/G530HSER1BPB1/)
*here's the mohan root method http://www.phonehorn.com/2014/11/root-samsung-galaxy-grand-prime/ (worked before with my past firmware with Android 4.4.4)
Philztouch and that root file may be only for Kitkat.
You can try Kingroot+SuperSume
