TWRP not booting - Verizon LG G3

Hi, i was using CM12.1, however I accepted an update and didn't figured out it was a CM13 Release, so when i dirty flashed the CM13 ROM over the CM 12.1 one, i got suspicious about something was wrong (due to the loading apps getting forever to configure)...the problem is that i tried then to patch gapps 6.0 and the recommended firmware to avoid problems but got many errors, then i tried to downgrade, however my TRWP just get stuck on the initial blue screen and just doesn't load, so i read what to do and did a downgrade using ToT back to Stock Verizone Firmware, and then tried to reinstall TWRP, i used ioroot to root my G3, then tried to reinstall TWRP but it always get an error, when the phone reboots to enter download mode it gets stuck in the LG Screen, and just stays there...i tried to enter TWRP like usual but the problem with the initial screen getting frozen is still there. I wanna get back to CM 12.1 but i have no idea how to make my TWRP work again
Hope you can help me out guys. Thanks

I have the exact same problem, except I cannot downgrade at all. I get to the Download mode and nothing happens. The TWRP only gets to the initial TeamWin screen so I can't do anything through that route. I have no GAPPS and it really sucks. Any help would be appreciated

Try with Root Browser, then look for the Root / sdcard path and delete the recovery.img files, in my case there were 3 of them.

I don't have any of those .img files I tried following that guide as well and nothing happened it got to like 4% then said update failed due to an error. any ideas? I just need to get TWRP working again so I can do a clean flash, is there anyway I can reinstall TWRP it was originally installed through goomanager. tried updating there and it just reboots recovery to get stuck on the teamwin splash screen.

I did it using the adb minimal tool, just placed the trwp 2.8.6.0 file into the root of sdcard folder, then using adb (phone must be connected to the laptop/pc in ethernet mode to be recognized) i ran
Code:
adb shell
command, after successfull initialize i used
Code:
su
(phone must be rooted to get a working su), and then i just ran the
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/recovery
command and the
Code:
dd if=/sdcard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
command, during install it says 0+0 files sent, so i think it detects the trwp is already installed but still do something that fix the brick. Hope you can get it working.

Did you give terminal root permissions by issuing the SU command and then granting the permissions on the phone?

If you're using SuperSU, launch the app and look at the list of apps with both permanantly granted or denied superuser permissions. You can click on an app there to change it. Are you using a local Terminal emulator app? If so, that's what would request SU access when you enter the command, but if you've done SU in Terminal on this ROM installation before and you granted permanent SU permissions for it, it would give it again automatically when you enter the SU command.
If you're using ADB via USB from a PC, and you authorized USB Debugging on the phone prompt when you connected from the PC, and you then enter the SU command through the PC, I'm not sure what app shows up in the SuperSU app.
You're welcome, good luck!

By the way, when using Download mode, what tool are you using with it? LG Flash Tool 2014? Did you previously install the Verizon specific LG drivers, reboot the PC, then connect the phone to the PC in Download mode to a USB 2.0 port with the original cable? Check in Device Manager to see if your phone is listed under Modems when your phone is in Download mode? It can take up to 5-10 minutes for the PC to load the driver you previously installed, each time you connect the phone to a different USB 2.0 port.
Sorry if any of this is repeating anything that's already been asked or suggested.
If you can get it to, I'd suggest flashing the 10B KDZ for the easiest to root with the Stump app in brute force mode, and put TWRP on with TWRP Manager.

ok so I figured out the permission denied...somehow my root access in dev options got to off I changed it to adb and got this one to work
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/recovery
but this one says /sdcard not found...I created the folder and it still says not found.
Code:
dd if=/sdcard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
where exactly does the recovery.img need to be located.
I am using LG Flash Tool 2014 and I have installed the specific drivers from lg and I can see my phone correctly in Device Manager. I just keep getting it stopped due to an error, but if I can get recovery working then I should be able to flash a stable CM for now.

the file goes in the root of storage, not in a folder, as shown in th pic.
if it says sdcard not found, you either entered the command wrong, or there is something wrong with your file system.
fyi, because the first command worked, you literally have no recovery now. thats what it does, empty the partition.

ok yes I have no recovery, that is correct...I put the recovery.img in /root and run the 2nd command again and it still says dd: /sdcard/recovery.img: No such file or directory
when I open up ES File Explorer it opens by default to /sdcard and immediately says /sdcard/ not found...if my file directory is messed up how do I go about getting it corrected?
edit: I used flashify and got TWRP back on successfully but it still won't go past teamwin splash screen....am I missing something I'm on cm 13.020151124-nightly-vs985.
is there a specific version of twrp I need for that nightly?

I'm attempting to wipe recovery again and try CWM to see if that will work.

unfortunately, i dont know how to fix it.
im betting stock wont flash because of whatever is damaged on your internal card.
i just looked back and noticed this all started with cm13. i have to wonder, how many phones are they going to break before they pull this update until a fix is found.
your is the first that i have come across that broke the internal card, but i have seen quite a few that broke the external.
im not suggesting you try this, as i really dont know what will happen.
as a last resort, you could try to zero out the data partition with dd code.
given the unknown damage to your card, i cant stress enough, this is a last resort, and may brick your phone.
normally, it should react like a factory reset, but if its still unable to use the internal properly afterwards, it very possibly may not boot fully or at all any more.
edit, as far as i know, the newest version is what they are using, but i dont know what that is specifically.

so I have recovery back on my phone but it won't go past splash screen, I can remove recovery to where I have no recovery at all, everytime I put recovery back on from an app like Flashify it is successful but I can't get past the Splash screen of twrp...if i can get twrp or any other recovery on my phone i should be fine that is what is hanging me up...is there another recovery I can use with CM13 other than TWRP so I can try that and if so how do I get it onto my phone, I can't seem to get fastboot to work so help on that might be useful.
when I try the kdz method to revert to stock it fails due to an error...when I try the dll version to revert to stock it sits on waiting for connection, if I unplug the phone it errors out

What error when flashing the KDZ? Most errors in LG Flash Tool 2014 should be totally ignored, just drag the dialog out of your way and don't press any buttons.

it says update failed due to an error and you have to hit retry or it does nothing...unless I need to just do nothing.
edit: IT WORKS YAY...all I did was retry and retry (definition of insanity) and the /sdcard just appeared then the dd command worked and I'm in recovery now yayayayayay
edit: edit: I did take out my eternal SD card so I am going to guess and say that that was the problem from the get go...anybody have any thoughts on that??
