Hi guys.
I have been reading the forum for a week now but just can't seem to handle this on my own.
Currently I am stuck on fastboot loop and can't seem to do much. I want to ask what possibilities do i have in my situation.
Here is how I got here. (Sorry if I got something wrong, I'll try my best to explain)
I have a LG G2 LS980 Sprint.
A month ago I rooted it and did did a nandroid back.
After that installed twrp and flashed a custom rom.
Two days ago accepted a OTA update and then went into bootloop but had access to download mode and recovery mode.
After that recovered using this tutorial.
Then sim card was not detected (actually it asked for pin but no network coverage was present, and said no sim card).
I rooted again using stump and downloaded auto rec to install custom recovery and then got fastboot loop.
I tried to flash recovery using fastboot. ( I downloaded openrecovery-twrp-2.8.4.0-ls980.zip unziped it and did 'fastboot flash recovery recovery.img')
Now I can't enter download nor recovery mode. Phone just show LG logo and after that fastboot loads and displays fastboot started udc_start.
Read a bunch of threads but not sure what exactly to do and what files / imgs to use. Any help will be greatly appreciated.

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.
So i saw there was an application update for my lg g2 (d802) so i decited to install it but now my lg is stuck in OTA mode and it wont boot up because of the secure boot error.... I can't access download mode or fastboot or recovery. It is pretty useless now . Please please help my. I really don't know what to do....

I have the LG G2 D802 (international)
I wanted to backup my whole system just in case something would go wrong. So I installed cwm and when I booted my phone in recovery mode it was giving me a 'secure boot error'. But I accidently made a backup with the cwm error (I thought it was still the original recovery but it wasn't) then iI installed twrp 2.7 for lg g2 and that worked just great =). I made my backup. But then there was an software update from android (not google play) so I clicked on the 'install update notification' and my phone turned of and back on. but it booted in twrp instead of the original recovery (duh!) I looked it up on internet and found a command line I had to fill in in the twrp menu (something with 'dd if=/' etc). that fixed the problem but still the update wasn't installed. So I installed my old recovery back (the backup I made but what wasn't the original recovery. I installed the cwm 'secure boot error" recovery back). After I click again on the 'install update notification' my phone went in a bootloop with the 'secure boot error' I fuxed that problem now through this xda thread:

But now my phone is stuck in fastboot mode, I tried these solutions but none of them helped...

http://forum.xda-developers.com/showthread.php?t=2477595
After all the fastboot commands are done an they all said 'OKAY' I rebooted my phone and in still booted in fastboot. \
Thats the whole story, and I again don't know what to do....
I'm in a very peculiar position here, where my LG G2 is stuck as the LG boot logo, but when plugged into my computer I have access to the internal storage. Here's how I got to this situation:
I previously owned a G2 on CM11 that had hardware issues. Before swapping it out due to those issues, I had made a backup using the package listed here, which created a few .img files, including boot.img.
On my new phone, I rooted, installed TWRP, made a backup of stock
Flashed Mahdi Rom
After flashing Mahdi Rom, my phone would immediately boot into fastboot, showing "fastboot started (new line) udc_start"
I did with the procedure listed here to be able to access download mode, and this was successful.
I then followed the procedure here to return to stock, but I got an error in LG FlashTools saying that I had the wrong model number. After a bit of digging around, it seems that this error may have been caused by the Mahdi Rom flash renaming my phone to "G2" instead of "d800".
After troubleshooting this for hours, I took a stab at flashing the boot.img file mentioned earlier through fastboot. Flashing this boot.img is what triggered the predicament I'm in now - I can access the phone's internal storage on my computer via USB, but it's stuck at the LG logo.
At this time, my phone will not ADB, fastboot, or enter recovery; I can only access download mode. When trying to enter recovery, it loads for about 1 second and then I'm kicked out and it goes back to the LG load screen.
Thank you in advance for any and all help

Holy **** it worked! Thank you for linking this, my D800 baby has been resurrected.
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.
greetings people,
a few days ago my friend brought me a phone for me to flash a custom rom onto it. I can't REGRET anything more then accepting this phone.
I rooted the phone on stock android 4.4.4 with Kingroot and after that, **** went down real bad.
I realised I couldn't acces recovery NOR download modus anymore, i try'd to boot into download/recovery with the hardware button way, but I also try'd to boot with adb reboot download / recovery
neither of those options worked, the phone either normally booted up or it kept trying to reboot with a black screen.
after I rooted it the boot image u get like " Samsung XXX "" were also gone.
after ALOT of searching and stuff and attempting things ive found a really old thread that stated to use fastboot reboot bootloader. I were really amazed that that worked but instead of booting up to the regular download modus it booted into fastboot, I read somewhere someone had the similair issue like me and they told him his boot img were corrupted. so ive headed to sammobile and downloaded the stock firmware for the device, I extracted the packages since I couldn't use odin because I am/was not able to acces download modus, while in fastboot i flashed the single boot.img with the command "Fastboot flash boot boot.img" it succeeded but after it succeeded I tried to boot it up but it fails booting to OS,recovery and download. it keeps attemping to reboot, I am CLUELESS at this point. I am able to try some things when I can enter that fastboot mode I had before but I can't acces the phone with ADB since it just keeps rebooting and stays inresponsible
I am planning to buy a USB JIGG, i use to have one but I can't find it anywhere.
any idea's/information would be soo helpful..
thanx in advance

Hi There, I just came across your thread, because I'm in the same position you are, fortunately though, I've managed to root this phone without any problems, however it seem though that there is no custom ROM available for this device, at least nothing past KK, and that one I found didn't seem so stable, I tried to flash it and came back with an error!! So my friend won't be able to bring his phone out of the Dark Ages!! at least it's Rooted! and now he may be able to use some apps that do require root, It's the best I can do at this point. I used the link below to root sucessfully:

I realize it's kinda late but luck to you my friend:fingers-crossed:
By the way, This one is the Dual Sim Version, don't know if that will make a difference?!
