[Q] enabling ADB during bootloop

I am rooted with custom recovery, stuck on logo screen. I Can get to DL mode, but not recovery to restore my backup. usb debugging is enabled on the device, but its the Verizon version so it needs "Ethernet" connectivity to communicate via adb. so as of now its not communicating. anyway to send reboot recovery command so I can back up? or am I going to have to flash all the way back to stock through KDZ? and if I do that, do I lose root, and recovery, having to start all over?

What do you mean you can't get to recovery?

Lol. I mean i when I hold volume down and power key sequence it still just boots to lg logo and loops. I can not boot into twrp. Only download mode. What partition is recovery located? I am starting to wonder if I wiped it?

Aaand are you sure you released and pressed the keys again when the lg-logo came up? Also you should be able to get to the white lg reset-screen even if you have empty recovery partition.

Yes, I was. But I guess my timing was bad. I eventually got in, and recovered. Thanks for responding

Bricked LG G2 D802

Hi Guyz, so i managed to brick my phone yesterday. Was running Optimus G3 and decided to flash CloudyG2 3.3. Followed the instructions did a full wipe but when rebooted LG logo would flash for a split second then screen goes blank. The screen is on because can see the back-light but nothing boots. Tried a couple more restarts but the same thing happens. I did take a TWRP backup prior but when i enter recovery mode and restore the backup, when it reboots i get the LG logo then the android animation but then it freezes/stops on the Android text.
I then tried flashing stock rom via LG Flash Tool, downloaded both kitkat and lollipop kdz files, entered download mode on phone and got the firmware update message, went through the process of flashing with the flash tool but when it comes to the software upgrade part, it gets to 2% then fails. with a message - Upgrade stopped due to an error. I get this message when trying to flash both kitkat and lollipop kdz files and i have tried on both windows 10 machine and windows 7 laptop.
As i have access to recovery i have tried restoring backup many times but it just gets stuck at after the android animation, i guess my next step is to try the tot flash method but im struggling to find a clear guide on how to do this so any advice would be helpful.
Cheers, Justin.

Thanks, actually shortly after i posted question it fixed itself... i tried flashing lollipop again, the software upgrade started and it got to 2% then error. I left the LG flash tool open with the error on screen, disconnected phone and rebooted the phone... it went past LG logo and got stuck in boot just after showing android animation, so then i plugged in phone (wanted to see if could access phone via windows whilst stuck at boot) and after a couple of minutes the software upgrade window started on my pc so checked phone and it had switched into Firmware Update mode and was updating... so all good now!! Lollipop has installed and phone all working.
^^^ This may help someone with similar problem.
Thanks,

You should've flashed the kitkat bootloder before.. If you want to go back to cloudy ,flash the kitkat bootlader again..

Vs980 bootlooping after return to stock

So I just came off a bricked device caused by autorec to install twrp. That bricked my device pretty hard. I was able to get into download mode by using the SRK tool. After that I used LG flash tool 2014 to revert back to stock but instead get caught in a bootloop. I can not boot into recovery but I can boot into download mode. The most I've gotten was a few times it booted past the verizon logo and began to optimize the apps when after about 90/167 it restarted and bootlooped again. Any help would be appreciated as I'm pretty sure it can be fixed I'm just doing something wrong.

You should have stock recovery installed if you KDZed. Turn the device on by holding power and volume down. when the LG logo appears, let go of the power button and press and hold it again , while holding power down the whole time. Follow the prompts to factory reset, which should fix the bootloop.

I was able to get it into recovery it just wasn't working last time I tried. Unfortunately, when I select factory reset and then yes it restarts the phone and that's it.

was able,to fix it. It just took a factory reset from recovery. The issue is it never worked before and would just reboot after the factory reset and still be stuck. Perhaps I let the battery run out on it and that kinda reset it and allowed a factory reset.

Now that I'm on 4.4.2 does anyone have a suggestion on a root and twrp installation method?

IORoot or StumpRoot
Use AutoRec for recovery. I did this with my VS980 less than a month ago after my data and cache partitions were corrupted and I had to KDZ.

lg v20 h918 twrp bootloop

so I was having some battery issues and wanted to reset. i for some reason went to settings reset instead of booting to twrp to reset. nonetheless it booted to twrp. I wanted an all the way clean data install so I hit format data and rebooted. now it just keeps booting into twrp. i restored a backup which sys successful but it still goes back to twrp. I can get into fastboot, recoveery. and download mode. I just cant boot into the system.. any help would be appreciated. with no kdz available I dont know what to do..
EDIT FIXED: so apparently you cannot boot to twrp to reset from the factory reset screen on the phone. once I booted to twrp manually and rebooted it started up. really weird.

having same issue with us996 now cant boot to system followed root instructions to factory reset now i cant boot to anything other than twrp whats the button combo and chould u provide detailed instructions please?

Press power and volume down at same time. When lg logo appears realeasw the power button for 1 sec and repress. Then when you get to the all white reset screen press yes and yes again on the next screen. This will get you back into twrp. You might need to reflash the recovery img(not sure, but I did). Restore your backup or whatever and then reboot system. Might have to format data within twrp prior to restore. Think I did that too.

pretty sure im screwed until a rom is released i tried what you said i chouldnt get a white screen to appear still went to twrp directly and it seems i accidently deleted my restore point >< can h918 flash on us996? even though its tmobile?

so i got it booting but it keeps rebooting after a getting to home screen a notification pops up and says android is upgrading when finished it reboots

For reasons I'll never understand, I ended up in this situation with my H918 after doing an accidental factory reset (tried entering TWRP but TWRP wasn't installed... oops!) and re-rooting. After installing TWRP 3.0.2-1, I was completely unable to boot to system. I tried reflashing various stock partitions and a custom ROM, relocked and unlocked the bootloader a few times, and wiped/formatted/reparitioned the crap out of the poor thing. In the end, the only thing that worked was to flash TWRP a second time. Go figure.
Thanks for being so thorough in describing what you tried on the road to success!

I keep getting sent to twrp. Not sure how to fix it. I can't boot android. Have tried reinstalling roms. nothing working.

when i use button combo to boot into twrp it go to twrp then starts to boot up phone and sits at lg logo after i tried restore a backup. even after factory reset it loads 100% but never boots up

since you're having this problem with TWRP , it means you've rooted the phone right?
asking cz i'm looking to get the LG V20 but don't know about the risk of it bootlooping itself, without rooting or anything like that, like it used
to happen on lg g4 and g3.
Thank you

You most likely don't need to go through all of those hoops in the link above.
Have you tried power on and volume down to go through the factory reset screens.
A bunch of us had this problem and it was because an update downloaded on it's own and the bootloader snoops it out and forces recovery to boot.
Just do the volume down + power button - as soon as you see the lg logo release power only then immediately re-press power and continue holding power and volume down until the factory reset screen pops up. Select yes and yes, (don't worry - if you have twrp recovery it can't reset). It will boot you into TWRP and I'm pretty sure it will delete the update files in fota folder.
In TWRP select reboot - system and it should boot normally like nothing happened.

I ran into this issue and did as you wrote to re-flash Lineage 14 and it WORKED! Took me hours to get to this post, but after some searching around i'm so relieved and so much less frustrated! Thank you for your input!
