Stuck at Firmware Update from 4.4 to Lolipop - G2 Q&A, Help & Troubleshooting

Stuck at Firmware Update, can't enter download mode
Noob here, was simply trying to update from 4.4 to Lollipop using the LG PC Suite.
I thought it was supposed to be straightforward but it basically got stuck at the Firmware Update screen, 0% with a "B64" and ROOTED text in red below.
I've been trying to enter the other modes, holding volume + and power but it just keeps on going back to the same screen.
Any help appreciated.

Firmware update screen is download mode. You can update from PC suite from there

Resolved!
Finally got it working so I'm posting this in case it might help someone in the future.
I found another tool - LG Mobile Support Tool that recognizes the device even in the "stuck" Firmware Update screen. I tried Options > Upgrade Recovery but it complained there wasn't enough space. How am I supposed to delete files when I can't even get into the phone?
Turns out, I can "wipe" user files by doing a factory reset using volume down + power. Did that and was able to upgrade using just the Mobile Support Tool.
And interestingly, after the upgrade completed files are still there.

Hold the power button until you get a black screen. Download LG Mobile Support tool and the LG Drivers. Plug USB In and then hold the Power + Volume Up key. On your screen, click Upgrade Recovery. From there, you can do a factory reset through download mode of your phone.

In case you did the latest firmware ota upd,there is a topic that can solve you problem as long as you can access TWRP(even if you didnt do the ota it will,i tried that myself) Here is what you need to do.
use TWRP's "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.
This will probably fix you problem when it has to do with any update.
Thanks for the responses. I finally fixed it.. I started the procedure from scratch with a new laptop and somehow it worked lol

It happened to me and now phone hanged in download mode and can not connect to pc. Did you have a solution?
Solve
Guys! I had the exact same problem today. My solution was to keep pressing the "try again" button every time the error appeared on my computer screen. It took some time but the error was appearing at different levels each time in this order : 45% 57% 65% 80% and next the instalation was completed. If it doesn't work try switching to another computer if you can. After the firmware update hits 100% your phone will restart and the LG logo will appear(the led changes its color during this process). At this point you have to just wait a while. Then a dialog box will appear saying that the applications on your phone are configuring themselves. After that your phone will start and work normaly. The cause of the error is the lack of memory on your phone. If those idiots working for LG would say "YOU DON'T HAVE ENOUGH STORING SPACE" this stuff would not happen.
The phone is not rooted!(IMPORTANT)
Phone name: LG G2
Phone model: D802
Old software: 4.4.2 (KitKat)
Actual software: 5.0.2 (Lollipop)
I hope this hellped you solving the problem.

Download lg flash tool.
Download lg g2 stock firmware.
Press volume up button and insert usb cable. You will see download mode.
Open lg flash tool and flash the kdz( original firmware) through flash tool.select cse flash.
My LG V20 got stuck on the Firmware Update screen. It appears every time I restart the phone and I have to take the battery out. If I start the phone plugged in it starts normally. I was able to do a factory reset, the phone started normally a few times without being plugged in, now it's back to the Firmware screen. I can use the phone but need to restart when it's plugged in. I hope Oreo Update will fix it. I don't know much about updates, but do big updates like that reinstall the drivers as well?
Hello everyone I also have this kind of experience so many times in my g2 mini.stuck on Firmware update. What I’m doing is,
1. remove the battery to turn it off. Plug your charger and before plugging it to your phone hold the volume down and plug in until tou see the android is updating; or
2. Just simply hold the powerbutton + volume down until you see Android is updating.
I would love to see your feedback if it helps.

Please help me! Nexus 10 problem!

I was using the Cyanogenmod nightly for lollipop, and an update came out. I downloaded the update through Cyanogenmod's built in updater, and now my tablet is stuck in a bootloop. I can get to bootloader, but I cant do anything aside from "Start". The volume buttons do nothing. I tried using NRT with the drivers reinstalled according to the directions in the program, but my laptop won't recognize the device! What do I do? Do I just have a giant expensive brick now??
TLDR: I cant get into recovery, bootloader can only "start", it wont boot to home screen, and my laptop (Windows 8.1) won't pick it up.
PLEASE HELP! I RELY ON THIS TABLET FOR EVERYTHING!

So... you can't use the volume buttons to scroll through the Bootloader menu??
One option would be to flash the factory images using fastboot... but obviously you will lose everything.
I would try to get into Recovery mode first and flash CM12 1/18/15. (1/30 has issues with nav var)...

Hold both volume buttons down and press power.
Then u scroll thru and choose recovery etc. If you just used volume down and power it won't scroll.

[Q] LG d802 recovery hell

Hi All,
I hoping some kind soul will guide/lend a helping hand here?
Here's my problem, I own an LG G2 d802, running kk4.2.2, rooted via towelroot.
Today I decided to for the first time to delve into the world of custom ROM's and what a mistake it was
Basically I downloaded TWRP for d802(img), gapps(d802 version), and cm Resurrection Remix and then I made the fatal mistake of using Flashify to flash TWRP to my phone and rebooting. After doing this I can no longer enter download mode, recovery mode, and when I try to go to either I get the ERROR: boot certification verify: secure booting error.
When I i plug my phone into my computer (drivers & LG support tool installed) my computer recognizes my device, however it displays around 10 or so removable drives i.e f, g, r etc and lots of messages appear saying i need to format them before they can be used and Support tool doesn't recognize my phone as being connected at all
I have searched lots of threads and now realize that Instead of using Flashify I should have used Autorec(lesson learned), I have also searched for possible solutions and the only
one which looks remotely viable is here:
http://forum.xda-developers.com/showthread.php?t=2582142
My only problem is I have LG G2 d802 32gb model and the files in the above guide/solution are for the LG G2 d802 16gb 10a and even then if they was the correct files I think i would still have a very hard time following/using the files to make my phone live again and also have no knowledge/exp with Linux distro's.
I am a total noob/idiot and don't have a clue how I am going to fix my phone and have pretty much pulled out whats left of my hair in despair!!
Please help me.
Kindest regards, Dark.

I am literally going insane now is there no one here that can even be so kind to say if the above is even the correct way for me to go? or point out a way which may be better or a step by step/link to things I need?
I really don't have the exp/confidence or knowledge to be bale to know if its correct or not and really don't want to make things worse by trying something that may not be right
Can find threads and websites which have similar type situation but all seem to have slightly different to my own as most can seem to have download mode or still be able to boot their OS but i cant do either.
is this below method any use for my situation?

You say in your original post you're running KK 4.2.2. 4.2.2 is Jellybean not KitKat, so which one are you running exactly?
If you didn't use AutoRec your bootloader should still be a Kitkat Bootloader since AutoRec's job is to downgrade your Bootloader to Jellybean.
There are 2 ways to access Recovery Mode on a G2 depending on the current Bootloader.
Method 1 (Jellybean Bootloader)
Turn G2 Off. Hold PWR + VOL DWN, when LG Logo appears let go and hold PWR + VOL DWN.
Method 2 (KitKat Bootloader)
Turn G2 Off. How PWR + VOL DWN, when LG Logo appears, let go and hold VOL UP + VOL DWN.
Do either of those work?

Well since you can't access Recovery Mode, you can't access Download Mode and your receiving a Boot Error, It sounds like your only option here is to follow this tutorial.
As for the files you need, you have a 32GB D802. Download this .7z package and extract it. You'll find all the .img files you need. Now follow the tutorial .

Nexus 7 No Recovery/No Fastboot RESOLVED PLEASE DELETE

Hey XDA!
Got my Nexus into some trouble today. I Was running stock rooted 5.0.2, received an OTA update for 5.1. Ran the update and it sent me to my TWRP 3.0 recovery. Restarted the device and found out the update did not work, leaving me at 5.0.2. Ran the update again like a tard, took my to the stock bootloader. TWRP is now no where to be found... In fact there is no recovery to be found. When I select the recovery option in the bootloader it goes to black screen then redirects back to the bootloader. When I select the "start" option, it's reboots the device taking me to the bootloader. I have attempted a hard restart with the power button but the device hangs on the Google logo forever. I have tried to use the Nexus Root Tool but it can't help me since the device won't connect via fastboot, or ADB.
Any help is appreciated.
Hallo,
got the same problem, how did you resolve it ??? Thanks a lot ...
Same here. I can't connect to the device by no means. How did you solve your problem?

you mention it wont connect via fastboot but you can still reboot with the pwr + vol- to get menus of some kind.. ? if the screen is backlite even just a blank screen but you can see it light up theres still hope. All i can say is try to reboot the device into fastboot an then try Nexus Root Toolkit an see if you can reset to Factory to restore the stock recovery partition along with reset the OS to which ever you select and start over .. Good Luck Flashing... the only way i can say your SOL is if when you plug it into your PC an it pops up with the error "Device Malfunctioned,....." then you SOL Good Luck Flashing :good:

Galaxy s4 Recovery mode issue Urgent

I need help and have no idea where to go. My phone restarted randomly like it usually does but It got stuck on this screen
http://forums.androidcentral.com/at...says-no-command-photo-27-04-2014-23-39-34.png
Sadly I had no backup for the device and am wondering if it's bricked. I can access the phone when I hold the power/ down volume/home button from time to time. I formatted the device hoping it would fix the issue. I managed to set up the device but I have to hold those specific buttons for it to work. Here are the device specs. I don't know what to do. I tried factory resetting it but with no luck. Every time i turn on the device I have to use that button order. I just have no idea what to do. I installed a stock rom via odin using this tutorial.
https://www.youtube.com/watch?v=LeYwhL1iS6k
Device: Samsung Galaxy s4 SGH-I337
Android : 4.4.4 kit kat
Edit: I have to hold volume down/home button/ power to turn it on which is quite annoying. I've never had this issue before. Is there a way to completely restore it to factory without having to do all this stuff? I tried doing it via recovery mode and in the phone itself. I get this screen https://cdn-images.xda-developers.com/direct/3/0/1/9/2/9/4/20120813002112.jpg
Which I usually get but then it goes straight to the odd recovery mode screen and not to the phone.
I found out something huge that might help! My volume up key isn't working so I'm assuming it's booting it straight into recovery mode for that reason. I read on a few sites saying I need the device repaired! I'm almost 100% sure thats the issue but correct me if im wrong. The volume up wont work at all.

The youtube video you mentioned was about how to root the i337. The video did not mentioned anything about stock rom installation via odin.
The video shows to install the nc1 kernel, then use the towel root to root and then install the NJ4 kernel back to work with system.
It appears that your system messed-up in installing the kernel.
You need to install the full firmware via odin. There is only one full firmware available for kit-kat. It is NB1 firmware with NC1 kernel cooked by muniz_ri. You can download the firmware from here.
Unrar the firmware and you will get .md5 file. Put your phone to download mode, load the .md5 file to AP slot of the odin and flash it.
If you have problem in flashing odin show the screen shot of odin error.
Once your phone is running fine, you can use towel root to root the phone. If you want to upgrade to NJ4 I will show you the direction then.
