D800 no recovery, boot certification verify - G2 Q&A, Help & Troubleshooting

So I tried flashing CM13 via TWRP and I did, but whenever I try to access the recovery it just shows the LG logo and the boot certification error. When I try to install a recovery via Autorec it shows an error when installing the loki tool, so I don't know what to do. Any help? CM13 works fine and I can boot to it, but I'm wondering how I can access my recovery again. Thanks

[Q] Stuck in TWRP

Good day
After using different methods to try and install a variety of ROMS inclduing CM11, MUIU, FirefoxOs and KitKat 4.4.4.2 Brannded, I'm stuck in the TWRP 2.6.3.2 gui after using flashify and not making a backup. When I sideload and install miui_g2_ws008_4.5.19_5b586f93ad_4.2 it installs sucessfully according to the log, but I get stuck in boot loop after gapps has been loaded in 1st boot. With cm-11-20140522-NIGHTLY-d802, openrecovery-twrp-2.7.0.0-d2vzw, philz_touch_5.15.0-d2vzw, TWRP_v2.3.3.0_P350 I get the Error Executing Binary Zip. When I sideload openrecovery-twrp-2.7.0.2-t03g it installs successfully, I select reboot, it ask me to install SuperSU I say yes and then get stuck in LG boot loop. LG flash tools get stuck at "waiting for connection" when I try to flash it with LGD800AT-01-V10d-310-410-AUG-14-2013 and LGD800_20130904_LGFLASHv160.

Unable to boot into twrp recovery after installing cm13 on t-mobile d801

I got cm 13 running on my d801 g2 the other day and I'm not a fan of it so I'm planning on flashing to cloudy g2 2.2 but now i am unable to boot into twrp. I enabled root, installed twrp and even enabled advanced reboot to boot directly into recovery but i keep getting secure booting error Cause: boot certification error which is what i was getting on stock android before getting cm13, i fixed the issue before with the kitkat auto rec app but I've read that auto rec can cause a hard brick if used in marshmallow. Trying to get into twrp through twrp, cm advanced reboot, hard key(power and vol down) recovery, flashify and adb reboot recovery command all cause the same error message. Any advice? I tried flashing twrp 3.0.0.4 and that put me into fastboot as does any other twrp version I've tried in flashify
lg g2 bricked

My computer brings up 15 disc partitions with only one partition containing data, one folder called image with files include adsp, cmnlib, mc_v2, modem, playread, wcnss and widevine they all have duplicates with different file types b00-b26 and mdt .

Help I am unable to boot into recovery

It has been 4 months I have flashed a custom ROM (Vibe UI 2.0) and then I wanted to change this ROM because in this ROM we can't install apps as it shows unable to install apps on your device
When I am trying to boot into recovery it is only showing the lenovo symbol (but I am able to boot into OS)
I tried to flash recovery again but it's still stuck on the lenovo logo(splash Screen)
I tried to flash through command prompt but the device is unable to boot into recovery showing that signal not reachable in cmd
I tried to flash using QFIL but it's showing error to flash ROM
Plzz help me!!!
It seems the recovery you are trying to install is not compatible with the current OS. Try other versions of TWRP.
Edit: You need TWRP 2.8.6.1 by Sevenmaxs

Weird One Plus 6T Behavior

Hello fellow XDA members!
My 6T, has a issue that i cant figure out! Its runs fine, currently on OS 10.3.8
But when i try to load a custom recovery (TWRP, Paint it Black) I enter the command on my pc (fastboot boot twrp.img) It says on my pc that it booted the recovery but on my phone it goes into fastboot mode logo, and stays there for like 10 seconds, and then i get the famous Qualcomm CrashDump Mode. I have restored the phone as per the instructions (https://forum.xda-developers.com/t/installing-updating-backup-and-restore-guide-for-op6-6t.4254987/) and the phone restore perfectly, but it wont let me flash a custom recovery to root it. Can someone help please?
Would you specify which version of TWRP you are trying to boot please?

Maybe try official twrp.
Hey, I'm having the same issue. Were you ever able to solve this?
Use this to boot twrp
Brettroth said:
Use this to boot twrp. Then in twrp advanced menu flash this twrp to make it permanent. Reboot to twrp.
