I'm stuck with "Security Error" on boot up

I have a Tmobile d801... was trying to flash a d802 4.2.2 rom with TWRP 2.6.3.2.

Install flashed fine... after install I have the Tmobile stock kernel save as a restore... so I restored the stock kernel and rebooted system.

Got bootloop... booted back into recovery. TWRP 2632 can take a very long time to wipe and restore so I flashed philz_touch_6.27.5-d801.

I guess that fail because when I boot into recovery I get a prompt in the top left...

Code:
[9110] Fastboot mode started
[9160] udc_start()

I can get into download mode but R&D tools fails at 45% with "T-Mobile USA D80110C_00.kdz"

Code:
18:52:51 : MODEL DLL Event : (13, 41)
18:52:58 : wParam : 13,     lParam = 42
18:53:04 : wParam : 13,     lParam = 43
18:53:10 : wParam : 13,     lParam = 44
18:53:17 : wParam : 13,     lParam = 45
18:53:19 : wParam : 6002,     lParam = 0
18:53:19 : #################################################
18:53:19 : Indirect Internal / PC to Phone send end
18:53:39 : wParam : 13,     lParam = 46

I try the TOT method with LGFlashTool but when I use the d801.dll it fails because it thinks the phone is a d802 because of the d802 rom I flashed.

I try TOT with d802.dll just to see if I could get something on the phone... but it fails on the modem check. kinda stuck in the middle of no mans land.

Is there a way to flash recovery and or a way to force LGFlashTool to continue with the d801 dll?

Thanks in advance.

[FIX] LG G2 "Booting Error" under LG Logo. Stuck in Boot Loop.

I received "Booting Error" below the LG logo and was then stuck in a boot loop. It happened to me after updating to Lollipop 5.0.2 and installing AutoRec.apk. This is the TWRP recovery program that you can install like any other app after rooting your LG G2. The cause for the problem is that I accidentally installed the AutoRec.apk for firmware's 4.x.x and not for Lollipop 5.0.x.

TO PREVENT THIS FROM HAPPENING DOWNLOAD & INSTALL '(D801) LG G2 AutoRec-Lollipop' FROM GOOGLE PLAY STORE :good:
