So I was relatively ok playing with my lg g2, rooted and have twrp 2.8.6.1 installed. It has been couple of months since I can't connect to freedompop/sprint network -- I can't change the cdma setting from nv to ruim/sim, I am thinking that it was the cause. Then I decided to upgrade twrp to 3.0.2, I boot into twrp, flash img, recovery, then I can't boot back to recovery. Something with fastboot. Surprisingly, I still can boot to system. Check root access, still have it. Then I used flashify to flash twrp back to 2.8.7 but to no avail, still the same thing, no recovery but boot into the system. Then I use autorec for ls980 on androidfilehost by bender_07, that's when things went down. Screen just black, not even lg flash screen, nor download mode, nor recovery. When I plugged the phone to computer, it asks to format multiple drives (15 or so), I am not sure where to go now. Anyone have any ideas?
-Found a solution, managed to get download mode working and tot-ing back

i was trying to update my twrp from twrp manager in my d800, i accidentally flashed the d850 version now my device wont load into recovery and i can not flash, i can get my device to load up if i hold power and down.
i just can not get into recovery it stuck oneith a black screen or lg logo.
i seem to fix it by using autorec but im having a hard time updating the recovery i keep getting an error
Get Flashify if u are able to boot into Android.
Hi,
I'm wondering if you could help me out. I bought a D800 G2 today from the internet. I rooted it and then used autorec to install twrp. I then created a backup and selected reboot to system. It then rebooted to a black screen and Now it will not boot. It just gets stuck on a black screen after the lg logo.
adb is working and I can get into twrp using adb commands. I can also get into download mode....
Thing is I have never had an LG phone before so I do not know how to get it to boot again. I read about two methods- KDZ and TOT but not sure which one I should use.
Thanks for any help
edit--tHANKS @thedoctor13th for the guidance...
Solution was to download custom rom onto a flash drive and use my otg to flash custom rom considering I was able to get into recovery. then update recovery and make a nandroid. phone's working to my knowledge. Haven't inserted a SIM into it yet. Will try that tomorrow.
I have installed Unofficial CM 13 successfully, but I forgot to root the device, so I go back and flash supersu file and reboot - I think I flashed wrong version for marshmallow. now phone stuck at cm boot animation, I have no recovery, only has access to download mode. I also have no access to phone through adb or fastboot.
I was in the similar situation before, where I was stuck at lg logo, and fix it by flashing stock rom (now I cannot find that thread), but now it tries to boot the rom, seems like a different situation.
What should I do?
lg g2 stuck on lg logo

Click to expand...
Click to collapse
just short connectors and flash all partations again.
So, I did brick my D802 in some way.
After a long history from cloudy g2-g3, rr, cm12, cm13, lineage 14.1, I clicked by mistake on the OTA of the lineage.
I thought I could stop the update once in the recovery, but I got stucked in the recovery bootloop. I got rid of it via recovery terminal, but system didn't boot. I tried reflashing lineage, nothing happened, I tried restoring a cm13 full backup, nothing happened, so I got back in download mode to restock with lollipop kdz (the one I used every time I restocked to change rom). It did not work, and I had to download a different KDZ to get to stock again.
Now, all the methods always used to root + recovery didn't work, so I manually rooted, installed the proper AUTOREC, but it didn't work (as I understand after hours of searching because supersu had updated himself in the meantime).
So I tried to install the TWRP image using flashify, it didn't work and corrupted something in my recovery. So i tried to unroot everything and reinstall the original root + supersu without letting him autoupdate. Not working.
Well, now I can boot and I can get in original lollipop rom, but I have no recovery and download mode appears but doesn't work anymore (once I had 3 COM ports when connected in download mode, now I can see only one; kdz flash does not sense the phone connected). When I try to open recovery I got the error "boot certification verify, secureboot error" in the top left corner of the screen, then a white page opens with the message "critical error" "demigod crash handler", volume up to download mode (that opens but does not work), volume down to reboot.
Now, I am stucked, I cannot find any suggestion of what to do to get the recovery working or to get the download mode working again.
Any help will be highly appreciated.
Thank you very much guys.

So I was installing twrp and everything went right until it didnt boot to the recovery and from then it keeps booting to lg logo and bootloader warning forever.
I know I can install the stock rom with lg up by I cannot enter download mode since the phone isnt technically turned off. Does anyoene have a solution.
It's my main phone and I literally cannot afford a phone right now.
A way to turn it off would be the solution. Battery was around 70% so it will take a long time to actually have 0%.
Update: I got to the fasboot menu from where I can run fastboot reboot recovery after installing twrp again. Now I have some mounting issues and I cannot flash any zip without entering bootloop. Im trying to use the shut down menu of twrp to try to enter download mode.
2nd Update: solved using lg up with the latest android version.
