Error while firmware Update

Hello Hyelton and other Team members.

I was trying to flash the German Lollipop rom for the LG G2. At 37% in the firmware update it gave me the ASSERT error. Since then I try different roms, currently trying the KitKat rom again, which errors around 70 tot 80 %, it differs everytime. I had TWRP installed but I can't seem to reach it anymore, perhaps it is gone after doing a CSE Flash?

Currently I'm stuck in the firmware update screen, it does connect with the computer, i can start the flashing procedure, though it gives an error somewhere on the way. I can't find much help to go around this error, have you guys run into this problem already?

Thanks!

Solved: I'm not sure how it got solved, like others I experienced I got more progress in % after each try. Eventually I went back to a Windows Vista pc instead of Windows 8, with more cpu power and went back from USB3 to 2.0. I noticed the flashing took longer to advance in procents then with the USB3 pc. I read about devices that don't flash quite well when the transfer speed is to high.
[G2 General] MicroMod777:
Try 27a bootstack.
[G2 General] snnail:
how can I do that? I cannot use Download Mode.

thank you
[G2 General] hyelton:
Your only way to getting back to stock is download mode.
[G2 General] nolageek:
I misread that line ... But I followed the TOT instructions for D800 - my phone doesn't appear in device manager at all though. Does the flash tool show any kind of progress meter? I ran it anyway and left it sit for ~2 hours but I couldn't tell anything was happening. It just said "Ready" the whole time after I clicked the yellow button.

Again, phone was in download mode. The only other screen I can get the phone into is "Hardware key control mode" but nothing works, I can switch to on, off, cancel, etc..
[G2 General] hyelton:
It won't flash unless lgemodem shows up under Ports and you have to change your com port to com41 otherwise it won't work. Also flashing only takes 5 min or so.

Try another USB port. Another usb cable.
[G2 General] frodoring:
Can annyone help me?
[G2 General] cyaiphone:
anyone know a solution to holding down volume up button and plugging USB in to get into download mode only to get a bunch of pop up messages asking me to format disk? When i plug in USB i get a bunch of local drive folders (H-S) and it wants me to format each one?

any ideas?

current status of phone is BRICKED

---------- Post added at 01:44 AM ---------- Previous post was at 01:38 AM ----------

I'm also thinking part of my problem is that i'm not quite sure if phone is completely off or just in a boot loop. Screen is entirely black, but just not sure if it's off or not. Any ideas how to get phone completely off? This makes me not want to ever get a phone without removable battery again.
[G2 General] MicroMod777:
Download 27a bootstack from xdaddeb resources sticky. Go into twrp, plug cable to computer n transfer to internal memory n flash it.
[G2 General] snnail:
After I did this, the volume up and plug the cable lead me into fastboot mode.
[G2 General] Swetnes:
The first boot for Lollipop takes a good 10 - 15 minutes before it even gets off the LG logo. Are you getting the pulsating light blue LED above the screen? If you are its working, just be patient.

Sent from my LG-D800
[G2 General] akshayk17j:
I have tried the process three times. Yesterday I waited 5-7 minutes and it did not start emitting light from the LED like it normally does during boot up. Right now I am running Kit Kat 4.4.2, it does not show that my phone is rooted in download mode and root checker app. I have also removed twrp.

After the software update (2/2) reaches 100% my phone reboots to lg logo and nothing else. I tried doing factory reset after lollipop had completed installation and still no luck.

It takes me a while to redownload and configure all my apps, so I don't want to try it again unless someone has solid advice.
[G2 General] sameerm02:
I downloaded stock Italy v30a and successfully installed it on my Indian d802 with LG flashtool 2014 :victory:

[G2 General] zottel1993:
Hello 2 short questions:

im on cusotm lp 5.02 with stock kk bootloader. to get stock lp can i use Germany 16GB D80230d_00.kdz or musst i first flash kk kdz and than ota to lp ?

Second one is whats the difference between kdz and tot method ?

EDIT:

have treid by my own. Direct flashing works. But after flashing my rotation isnt working anymore...
[G2 General] Togglebg:
Do you know if I can use D80230d_00.kdz on my 16 gb G2? When I use the website that matches IMEI to kdz it gives me D80220H_00.kdz which is KitKat and I want Lollipop.
[G2 General] zottel1993:
I pick the one from cow(first Link) than sub dir lollipop and than 16gb and my language... I came from custom lollipop with kk baseband and modem... If u have a d802 16 gb it should work... Only issue is rotation does not work. But had this already in kk roms
[G2 General] arungk2:
finally dismantled the phone

So i have finally dismantled the phone to check the real model no. Of this spoilt brat that has given me sleepless nights. And guess what my D802 32gb international turns out to be a D800 as mentioned on the motherboard. Days of reading downloading and flashing had gone waste. Now friends i dont know which rom to flash. I have to start all over again. Please guide me.
[G2 General] hyelton:
Then flash a D800 tot.
[G2 General] Togglebg:
I just flashed said rom and everything works fine including rotation.
[G2 General] CryptKilla:
Does any1 knows whats the different between this two kdz ?

Europe OPEN D80220H_00.kdz

Europe OPEN D80220D_00.kdz

Tnx
[G2 General] igos2:
I have the exact some question, I think 20H is the latest in date.
[G2 General] hyelton:
The difference is 20H is newer.
[G2 General] killahax:
So when i go into download mode i get and error msg after the blue download display comes on.. Why wont download mode work. ****s pissin me off

Im on tmobile

And i cant take screen shot

First picture is what i get going into download mode then after that it shows error with numbers on top left then screen goes blank with a glow..

The second picture i have is what it suppost to so.. Why dont i get that?
[G2 General] hyelton:
First of all don't quote the entire OP..

So could you take a pic of that error you see when it flashes blank. I've never seen that before. If your getting an error in download mode you might have a actual brick there.
[G2 General] killahax:
As stated i cant take a picture... And if its bricked why am i able to still use the phone?
[G2 General] hyelton:
I didn't say screenshot I said picture.

You never mentioned you can still use your phone...

Need to know what that message says, as it could say anything.. Never seen that error before. Are you sure your phone doesn't have any security software installed like mcafee?
[G2 General] killahax:
Sure doesnt..

Similiar to this error..

I just want to go back to main oem status.. But when i click options in the phone to do factory reset it just reboots into recorey twerp.. 2.8
[G2 General] mualde:
Hi I checked the forum and I didn't find any answer is there way to turn back to stock on an Mac OsX PC? Thanks in advance.
[G2 General] hyelton:
You'll need a PC. Or use bootcamp
[G2 General] mualde:
If i can do with bootcamp than that's perfect. Thank u very much.
[G2 General] killahax:
Why wont it let me go to stock ?
[G2 General] hyelton:
Why what won't let you go back to stock? I'm assuming you mean you still cannot get into download mode.

When you edit posts I don't see it, I only get notifications for replys or posts.

The recovery/boot up message at the top shouldn't have anything to do with download mode.

So when you hold volume up and plug in usb as soon as you see the first screen do you let go of the volume up key? And leave it there and it automatically goes to a blank screen?
[G2 General] killahax:
when you hold volume button then plug in it goes into dl mode then give me an error messege on top left where the words are usually.. then the screen goes blank with a little light in the back round.... and I am able to get into twrp and use my current rom I am on as normal.. my phone wont let me go back to oem rom and

kernel when I do factory reset in the phone settings , it reboots to recovery mode..

also the drivers install for the lg, but when I plug in my phone for download mode my computer pops up 10 different windows saying external hard drive needs to reformatted for the phone. but when my phone is turned on for normal use and I plug in the phone the computer has no problem identifying the lg phone
[G2 General] lablunk:
I have used the TOT method before with perfect results. However, I have needed to do it again and now my G2 will not recognize my SIM card. Any ideas?
[G2 General] hyelton:
Did you flash the correct model? If so did you perform a factory reset a couple of times after flashing?
[G2 General] lablunk:
Yes, I have flashed the correct model. I have actually tried both of the Verizon tots that are supplied in the first post of this thread. I have also performed a reset several times.

I know it's not the SIM card because it works fine in other phones.

Thanks!
[G2 General] killahax:
this is what happens when I try and go into download mode.....

download mode is not an option for me as what it looks like
[G2 General] shubdya4u:
Stuck on download mode. Did a hard reboot but phone still ends up in firmware mode. Phone doesnt gets detected in device manager in ports section. It shows LGE android phone only. Tried installing again the drivers no success
[G2 General] hyelton:
LGE under ports is what you want..
[G2 General] happiness4u:
Hi [MENTION=2607037]hyelton[/MENTION], will you update the lollipop firmware in your site with 30B for 32gb? :)
[G2 General] shubdya4u:
LGE under ports is what you want..

Hey, can you see that my phone isnt being getting detected under the ports section. Although I had uninstalled the drivers ,restarted the system and again installed. And the phone is locked into download mode only. Even if I do hard reboot it boots into download mode. :confused:
[G2 General] hyelton:
Its being detected but the drivers are not installed for it.

So you installed the drivers from the OP right? DId you try and select the LGE one and install drivers from Windows update?
[G2 General] shubdya4u:
http://pho.to/9I7hZ

Yes I do have installed as you can see from the installed programs list. Yesterday it worked but accidentally usb cable got snapped while updating the firmware and from then onwards the phone is in download mode only.

I tried for windows update also but nothing materialized
[G2 General] hyelton:
Try another PC? and did you try to install via windows update?
[G2 General] Retep117:
Still stuck in boot loop

So I followed your tutorial, and in the end the result was that it has been reverted to stock, but the phone is stuck in a boot loop. It will start up fine but then after roughly 2 or 3 minutes it will restart over and over until the battery dies. I have tried factory resets, and have even taken the phone apart to determine that it is the model that I thought that it was. Is there any way to get the phone out of this semi-bricked mode?
[G2 General] hyelton:
Usually that happens if you flashed a wrong kdz or tot file. DId you try to reflash?
[G2 General] shubdya4u:
Tried on different PC still the same...........phone getting listed in device manager under the name Other devices CDC and LGE android phone
[G2 General] Retep117:
Still stuck in boot loop

Yeah I tried re-flashing both of the .tot files that are available for the D800, but same problem both times. The only two options are the ones in /AT&T right?
[G2 General] talvigi:
after deciding to go back to ZVC (my phone was already on ZVC as i bought it used/second hand). I followed the method shared by official.xian here: "http://xdaforums.com/sprint-g2/general/how-to-restore-downgrade-install-t2863050" and flashed this LS980ZVC_12.tot from here "http://storagecow.eu/index.php?dir=Xda%2FLG+G2%2FStock%2FSprint%2F".

My phone now does not recognize my non Sprint/AT&T SIM card and the NFC soft button is always blinking and it every time shows the Hands free activition
[G2 General] guitarboy021:
About the NFC thing.. I think its a problem with KK.. As i had that since the first time I updated to KK from JB.. Even then when i soft bricked my phone, i successfully flashed a kdz and it still has the same prob. So I guess u can rule out the NFC blinking. :p
[G2 General] Withering420:
Can't change COM port.

I'm trying everything in the instructions but COM port wont show up. Im on the ls980 model and any help would be much appreciated.
[G2 General] hyelton:
So phone is in download mode connected to USB and your looking under the ports tab in device manager for LGEModem?
[G2 General] Withering420:
Yes and the ports tab option isn't even available. I've tried all three USB ports, and reinstalled the LG drivers, and I have restarted my computer. I actually just got stuck in a boot loop.

Att d800 update

Hello, I just bought an ATT D800 32GB LG G2 but im still stock on 4.4.2......... I cant update pls help me.:rolleyes::rolleyes:
[G2 General] hyelton:
Well you didn't fully explain so I'm assuming your wanting to ota update it. And I'm assuming your not on AT&T as the reason you cannot update. You just have an AT&T sim in it to update. Or go with a custom rom.
[G2 General] danieldp1990:
I just want to upgrade from 4.4.2 to stock kitkat or lollipop if its out, is there a way to do it without OTA? im using a different sim on the phone not ATT. maybe manually flash how?
[G2 General] hyelton:
There's plenty of guides on how to root, flash twrp and flash lollipop. You'll have to root to get it.
[G2 General] slackwaresupport:
error

mine says: ERROR partition was changed. then fails..
[G2 General] Mako0:
Someone knows how to find Italy 30b 32gb kdz??

I'm on 30a but I have root so I cant install 30b OTA and in firmware list there is only 16gb...

Or maybe they never release this file due to blablabla??
[G2 General] hyelton:
So far only 30a. If its available for your exact phone go to lgkdz.com and enter your IMEI. But otherwise I dont see it yet.
[G2 General] Mako0:
This is exactly what I need, thank you :good:

I hope that this update won't cut my memory.. I trust xda more than LG "assistance"..
[G2 General] hyelton:
Sorry for the late uploads, I have updated the links with new firmwares for the G2.
[G2 General] hutjeflut:
OTA Updates

Is it normal that you cannot update trough OTA after flashing with a .KDZ file.

my Phone ran into a bootloop on 210E and had to flash 220H trough .KDZ and since i cant find the OTA update (europe open) foor lollipop but i know it has bin released.

my phone isnt rooted or anything.

Does .kdz flashing break OTA updates in the future or is there another reason its not finding the update?
[G2 General] Redbyte97:
didnt work... phone started immediatly to fastboot
[G2 General] Gi3M0:
Hello,I have a D-802 model and I bought it in Slovenia.Now I don`t know,what to choose there in R&D tool under country/language??

[G2 General] thenewak:
Thanks for the guide, but if you could change the download mode method to hold up button and plug in usb. I was trying for a while lol then found it on youtube.
[G2 General] 4rsenal:
Does this new link that you get after putting in the IMEI fix the stuck at 49% issue?
[G2 General] hyelton:
No it does not... It's will give you the SAME exact kdz file that is hosted on my server ...
[G2 General] 4rsenal:
Do you have any idea how or if it is possible?
[G2 General] hyelton:
It's just hit and miss. Idk Ive flashed several different models on my same machine and not once had an issue
[G2 General] 4rsenal:
So do you have any recommendations? I have a bricked phone here lol. Are there any alternate ways? Possible alternatives?
[G2 General] Kickoff:
It is really unbelievable how many people are struggling with this issue including me. In my case - I assume - the reason might be that I tried to install European Open 10B KDZ to my SEA10B handset because of the Lte issue. After that I had the security pin issue and after hard reset I lost 16GB. Solved the problem. However, since then I have had several issues in TWRP. No cache wipe, no system mount, bootloop, no restore ability, twrp backup disappeared....

On my home PC (Windows 8.1 64bit) I have always the 49% issue. On my work notebook (same OS) I can recover the system but always the SEA10B KDZ. Flashtool does not work.

Yesterday I sideloaded the new AOSP KitKat ROM and twrp said no OS. I let it to boot and it worked. For a while I will go with this, but I miss the Rayglobe ROM which I cannot install as well.

I would really like to know the reason behind the whole thing, mainly the LG security pin issue.

PS: the whole mismatch was caused by LG that is selling only the 16GB G2 in Hungary officially. Why this?????!!!

[MENTION=4264247]wars045[/MENTION] (# 869) NOT true , i use Windows 8.1 64 bit , and all is fine ... :good:
[G2 General] terragady:
Hey, im quite new with LG but I just bought G2 for my girlfriend. It is D802 16GB but branded (logo on the start). I wanted to put a stock image there and than just update to 5.0.2 (from what I read it is only possible through LG suite)

How do I know which stock ROM do I need? Is it any easy way to check it?

Will I have a warranty after this? Like phone came with branding but now it will be pure stock?

I do not any S-OFF and root as it is just for my girlfriend, just need newest, unbranded firmware/ROM

last, will be lollipop available after this as update?
[G2 General] hyelton:
No flashing doesn't break as flashing is the same lg uses. Make sure you performed a factory reset after flashing as well that your model/imei is listed with your carrier.
[G2 General] hyelton:
Yea there's a link in the Op for finding for wares directly for your phone. Lgkdz.com
[G2 General] terragady:
So I understand that I can flash any rom (stock rom ofc), but if it will not match my IMEI I will not get any updates (automatic ones)?
[G2 General] hyelton:
These are not Roms. These are stock factory firmwares :)

You can flash any firmware as long as it matches your model # and size.
[G2 General] terragady:
Aren't they roms as well? Pretty heavy as for a firmware only.
[G2 General] hyelton:
There's custom Roms yes. But kdz and tot that use flash tool are stock factory firmwares. Every file in this thread are stock.
[G2 General] terragady:
I know that there are custom roms as well. But these kdz files contains also stock rom (android) and stock firmware (boot, hboot etc)?

If I will write it on custom rom it will erase it and put stock rom, right? :)
[G2 General] hyelton:
Yes. As I said these are 100% stock files. You can use the tools in the OP when you want to flash back from a custom rom.
[G2 General] hyelton:
Well first of all to fix you have to be in download mode..

Also are you sure you flashed your correct model etc?
[G2 General] androlocks:
Finally return to stock after wasting a day
[G2 General] hyelton:
If you returned to stock then the day wasn't wasted :). It only takes 20 min in total after you download which depends on your connection.
[G2 General] androlocks:
Ofcourse yeah!! but i did alot of procedures from other forums then i get the right place
[G2 General] hyelton:
Ahh yeah XDA is the place :)

Did you make sure lgemodem shows up under ports in device manager?
[G2 General] ceza1380:
I want to ask you guys that Lollipop for my country has been uploaded to the LG servers so my question is that if that kdz baseband has special settings for my signal and improve it or does it same with Open Europe kdz. If I flash baseband from kdz which is for my country does it help my signal problems? If yes how can I pull baseband from kdz and make it flashable zip file?

d800 firmware

dear sir i need stock firmware for my lg g2 d800 32gb

from the link on the first page i see that d800 firmware is only under at&t

both firmware are .zip files and one is .dll

please tell me if these .zip files are kdz or tot

please help and tell me if i am correct or not
[G2 General] hyelton:
Just flash the kdz or if there's an ota update it will flash the modem. You cannot run the lollipop modem on kitkat.
[G2 General] hyelton:
Well if you'd read the OP you'd know...

D850 IS the AT&T model. Which means TOT method only. You follow the tot method and extract the zip to get the tot file.

The D850 only comes in 32Gb
