Got an H910 which has been fine for the longest time. It was running LOS17.1 with nothing else besides magisk installed. It was also the official release.
A week ago i decided I wanted LOS18.1 instead, but I got multiple E1001 errors unable to modify System partition.
Someone suggested I went back to stock and root again or something, so i flashed Kitkat zip and have since been stuck on an endless loop of "no command" recovery mode.
my device is still being picked up as US996, but despite all my attempts I can't seem to be able to flash anything. LGUP always succeeds but the second the devide reboots the "erasing.." screen is shown for a split second before going into an endless loop of turning on and off the screen with "no command", and still showing as US996.
in theory fastboot was already unlocked but I don't think it's the case anymore after the kitkat file thing.
I'm currently out of ideas. Am I missing something?
Any help would be appreciated.

Did you flash the nougat kdz in the dirtysanta root guide? I had a kernel crash problem and started over to fix, but I didn't flash a KitKat ROM in LGUp

Hi,
I was on a rooted android 4.4.2 official, when i tried to install custom recovery using Flashify.
https://play.google.com/store/apps/details?id=com.cgollner.flashify
There was the Secure booting error and booted normaly.I found out that this was not possible so i quit.
Today a got an update from LG so i installed it. The phone rebooted giving the Secure booting error, and it stayed black screen.
Googling i found this tread
http://forum.xda-developers.com/showthread.php?t=2582142
I folowed it but i thought since my phone had problem with it's recovery, just flashing the recovery.img would be ok.
I restarted the phone bat it would not start. It desplays the lg logo restarts, lg logo restarts.
I can boot the recovery but it does not work. When i press recover it just restarts.
I cant boot download mode or anything else, i have been googling the hole day.
I would apricciate your help. It is a one month old phone.....
Thanks

are u stuck in cmw recovery??
Stock recovery.... :/
Sent from my GT-I9100 using XDA Free mobile app
Same Problem here! Exact Same
Also having this issue, stuck in the secure boot loop, can't get to download mode.
Im exactly the same - im stuck in TWRP and cant boot into Download mode at all - just get the LG Bootscreen then straight into TWRP Recovery no matter what i do
Did we all except some kind of update from LG........ i wonder if this the link here and is now a common problem?
Mine was this and i thought it was just an app update for the stock apps and now im stuck big time
Any luck guys or solutions then please post here so we can keep it together and help each other!
Yeah I got an OTA update for my D803-Bell model, upon restart entered the secure boot error loop.
Sounds like, via this thread that it's commonly happening to people who had TWRP or CWM (or even aborted / possibly never completed installs like me) got nailed.
As per that thread, and everything else, I've tried every option possible -- no download mode. Recovery mode doesn't restore anything, just resterts to lg logo -> secure boot error -> black screen. Shows as QSHSUSB_BULK in windows/linux, and I can see those 25 partitions in linux (but reflashing openrecoverytwrp__.img over the recovery partition didn't help. I'm waiting to find out how I can make my own copies of those various partitions listed, from another D803-Bell model I have access to. All the D803 .img files on those links in that thread, appear to not contain D803 Bell stuff, just Telus, Rogers, etc... so I'll likely have to source my own.
I just took a shot in the dark recommended by a friend -- and fixed my phone.
I zeroed out the 'fota' partition on the phone. As seen in this thread ; http://forum.xda-developers.com/showthread.php?t=2451696
Just did a dd if=/dev/zero overtop of the fota partition, which was 25 for me from my linux box. One quick power cycle later, and I'm fully functional again, and the OTA update that killed me is still showing as available again.
While on a developer preview of Android N with my unlocked rooted phone and TWRP 3.0.2-1, I accidentally ran the September OTA. The OTA failed, but left a mess behind with the phone rebooting 4-5 times a day.
Today, I decided to fix the problem, so I flashed the latest official image (NRD90U). Complete wipe, but since I have backups, I considered it to be no big deal. Turns out it was
The phone is now a boot loop (corrupt warning -> google logo -> corrupt warning -> google logo...). Reflashing changes nothing. Trying to boot (fastboot boot) TWRP (any version) does not work (it just goes into the boot loop). Tried to downgrade back to 6, same problem. Nothing seems to work.
Somehow, something is still ****ed up on the phone, but I have no idea what. This seems to be very similar to this thread (http://forum.xda-developers.com/nexus-6p/help/help-help-help-hard-bricked-6p-t3428225/page3), but there does not seem to be a solution.
Is it definitely bricked or is there anything I can do from fastboot to try and fix this? I am unlocked. I just need a stupid TWRP so I can restore my backup and hopefully get back to a working state from there.
PS: I'm sure I downloaded the right image and flashed it properly.
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.
Not sure will it help but you may give it a try:

Having a helluva nightmare right now with this LG V20 US996. Updated it to US99610f with no problems then proceeded with DirtyElf to unlock, however instead of going with SuperSU I went ahead and popped on Magisk 11.6. After exiting TWRP my device kept rebooting back to the LG logo so I went to reload the KDZ for 10f in download mode and for whatever reason it kept getting stuck at 4% in LGUP. I was still able to access TWRP so I went there and flashed the 10f/with root found on XDA and that looks like it fscked things up even more now as the device keeps rebooting to the warning screen you get when the bootloader is unlocked. I can't seem to access TWRP anymore either! I can however still access download mode, but same thing as before getting stuck at 4% in LGUP... any suggestions?!
Why aren't you asking in the Dirty Elf thread?
I'll try to summarise it.
Unlocked my bootloader.
Tried rooting by flashing twrp and then installing supersu (i think i installed a corrupted version, as my phone did not go past the logo).
Deleted all system and cache to install lineageos, hoping it would fix it. It did, but i was unable to use my mobile data.
So i tried flashing the stock firmware for my phone ( H87020f_00_EEO_GB_OP_0817.kdz ) using uppercut, as LGUP did not recognise my phone.
Both twrp recovery and lineage were deleted.
It's back to the old boot sequence for LG phones but it gets stuck at the LG Logo "LG Lifes's Good".
The boot up sequence is, Bootloader unlocked message>LG G6 ThinQ>"Erasing">Bootloader unlocked message>LG G6 ThinQ>LG Logo. and it just stays there, tried waiting for 3 hours (i fell asleep), and it was still stuck.
I seriously need any help i can get for fixing this. I know that i'm an idiot for not backing anything up.
Fixed it

I fixed it, i installed the oldest version of the stock firmware using uppercut and now its working again. That was easier than i thought.
