Help with D800 ""model information check failed""

No matter what I've tried, I get a failure ""model information check failed". I'm definitely using D800 files, but I don't know if it's the right ones. The G2 is stock, unrooted, up to date with the latest AT&T updates. But it keeps turning off, like the battery is dead although it was charged fully when the problem started, and I've recharged it (which isn't that easy with this problem).

I don't even know for sure if this is the correct method to try, and if there is a better place to find out what to do, I'd appreciate it - so far, I've had no responses in the XDA assist section (http://xdaforums.com/general/xda-assist/lg-g2-shuts-boot-random-t3269081).

I have some trouble getting it into download mode without shutting down right away. I usually can't get to the boot screen, never past it, and even doing a factory reset seems to fail due to shutting down soon after requesting it.

Anyone have any ideas?

Use tot method

[G2 General] hyelton:
If it's stock and shutting off that sounds like a hardware issue...

Also the error your getting is due to not using a USB 2.0 port, USB 3.0 won't work. Or using a bad cable or not an lg cable. And sometimes it's due to the computer.
[G2 General] martyfried:
Thanks; It does act like hardware; don't know if you saw my original thread, but it happened because I tried to unlock it from AT&T by using a Project Fi sim in a nano to micro adapter. It may not have liked the Project Fi sim. I don't know if that would cause a hardware failure, but I have no idea what it might have done. Fortunately, I have a Nexus 5X on Project Fi, but I'd really like to get my otherwise perfect G2 working.

I've tried two cables, neither original. I'm not sure which cable is the original one. I'm definitely not using USB 3, but I am using a Windows Vista VM running under Linux. It's the only Windows system I have.

It seems the problem is that it's not getting anything back from the phone. Everything is blank.

Just successfully restored my DEU LG G2 (D802) with flash tool method and kdz file! Thaks a lot you just saved my life :D

Whether it can provide additional LS980 TOT file
[G2 General] hyelton:
Huh?? Also please don't quote the entire OP it can make the thread hard to go through. There is an LS980 tot in the Op
[G2 General] linyincsz:
I was wrong too many references i'm sorry, I see from your file after ZVE no updated version. Thank you for sharing, so that everything becomes simple and easy. But recently sprint updated several versions, upgrades become very troublesome. Can you offer some help?
[G2 General] hyelton:
What sort of help are you needing? Yeah to me sprint sucks including there phones software lol. But sadly no new firmwares / tots so everything would have to be OTA updated. But when it comes to any trouble shooting with problems with the sprint software I can't help much as I don't and never owned a sprint G2.
[G2 General] DCUnited*Fan:
Thanks! This made it possible to resurrect my bricked LG G2 LS980 from Sprint.

Thanks again!
[G2 General] hyelton:
Your welcome! :). Glad it fixed it
[G2 General] quickfastgoninja:
My computer only has USB 3.0 ports. Any way to work around this?
[G2 General] hyelton:
No it'll only work with USB 2.0 ports. It will just fail with USB 3.0
[G2 General] Pr0fess0rX:
Guys, I can't get the windows to detect the device; I've tried 3 machines 2 with windows 7 and one windows 10 and with different 2 cables and both windows the driver signature enforcement was disabled.

What could be the issues!? note that I can't boot into the ROM because of a bootloop and can't also access the recovery
[G2 General] hyelton:
The screen shot doesn't show anything. You don't need MTP in download mode it's supposed to be like that. Your looking in the wrong spot. You need the com port under the commutation ports tab.

You also need to make sure the phone is in download mode and not constantly boot looping.
[G2 General] Pr0fess0rX:
Do you mean this?

If that so, why the app can't find the device?
[G2 General] hyelton:
Yes. That means it's detected.

What app? What method are you trying to use? If the tot method it's not because you haven't set it to com41.

If kdz method make sure your using a USB 2.0 port as USB 3.0 won't work. Along with using the cable that came with the phone.

What error are you getting?
[G2 General] sayyro:
SOLVED !!!

I solved this issue by installing jellybean first then kitkat then lolipop :)
[G2 General] hyelton:
What issue? You mean Above? ^^ you must get it working first for it to flash :p
[G2 General] Pr0fess0rX:
I am using KDZ and I've tried on both USB 3.0 and 2.0
[G2 General] hyelton:
Are you clicking okay on the server error window or just dragging it? Clicking ok will cancel the flash. You just drag that window over. That error is normal.
[G2 General] Pr0fess0rX:
whether I drag it away or keep it the main windows doesn't continue to install. The following is the error details from the event viewer

The point I've did this upgrade two times before and was working well!
[G2 General] hyelton:
Next is to download the kdz using a download manager unless that's the same exact downloaded kdz from last time

If that still doesn't work you might have to do the tot method first then update using the kdz method. Some roms have been known to cause issues with kdz method.
[G2 General] Pr0fess0rX:
I will try to redownload the kdz file and try again and will get back to you then.

Thanks for your support.

---------- Post added at 10:01 PM ---------- Previous post was at 09:14 PM ----------

Now I redownloaded the kdz file and the same error here; I was on cm13 so I might need to use TOT method as you mentioned by i couldn't find a URL for downloading 32gb LTE for D802
[G2 General] hyelton:
There's a tot in the tot folder where the kdz files are at in the Op :) it could had been CM
[G2 General] Pr0fess0rX:
Inside this path: http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/D802+tot/ three file and I believe that's for AT&T. I am located outside USA, will the 32b file work for me?
[G2 General] hyelton:
The AT&T version is the D800. If you have a D802 then you would flash the D802 tot :) just make sure you use the 32Gb one.
[G2 General] Pr0fess0rX:
Thank you buddy very much, the phone is now working. I had to use both methods; first used the TOT method to get the phone up and running using kitkat then used KDZ method to upgrade to the latest lollipop.

Thanks again [MENTION=2607037]hyelton[/MENTION]
[G2 General] hyelton:
Awesome! Glad it finally worked! Yeah most likely due to CM
[G2 General] tvcat-xda:
hey guy, if i flash the kdz will i lose the installed app? thanks.
[G2 General] Qiram:
hello, i used to try the first method and it works flawlessly :good:

but, is it necesssary to factory reset the device? with the power vol down method?

thank you in advance:D

---------- Post added at 04:16 PM ---------- Previous post was at 04:10 PM ----------

based on the information from the first page, it will not erase the app if you flash with normal method :o
[G2 General] hyelton:
Yes as you'll want to do CSE flash.
[G2 General] hyelton:
It doesn't hurt to do so after flashing. But you need to if you didn't do CSE flash

It's never recommended to use normal flash as it can cause problems.
[G2 General] y300owner:
guys I did the TOT method and right now my phone has the red light blinking. What should I do now?

Like LG Flashtool says PASS!! (359 sec). My phone is connected and it won't wake up and is flashing red. Should I disonnect? or stop LG Flashtool?
[G2 General] tvcat-xda:
i understand that CSE will delete all like factory reset.

just not sure about the "normal flash" mode.
[G2 General] hyelton:
How long are you giving it? It can take up to 10 min. Also did you flash the correct model?
[G2 General] hyelton:
Never use normal. It doesn't wipe data, which can cause problems.
[G2 General] Qiram:
So it's ok if i didn't factory reset the device, right?

I want to restore some stock apps that i've deleted. I have to use normal flash or cse?

Which is i don't want to delete all of my apps and setting :)
[G2 General] hyelton:
You'll need to do CSE flash it will wipe everything. When using this method of you don't wipe it'll cause issues.
[G2 General] y300owner:
I did full wipe option but it seems my entire 'stock recovery' is fu*cked. going to make a new thread.

In the hard reset option it says "rooted" but when I try enabling the root access via application, it says "root not detected". Stock recovery has red escalation mark.

Root achieved -> http://xdaforums.com/lg-g3/orig-development/root-stump-root-lg-g3-sprint-verizon-t2850906
[G2 General] scared_bear:
I own a Verizon LGG2 updated to Lollipop 5.0.2. I was getting crazy because the battery started to dry out in three to four hrs.

Used the TOT method described in this thread and everything worked like a charm. I have KitKat again in my phone and no more battery issue.

Thanks a lot
[G2 General] yijit:
Hi there, I would love if there is anyone willing to do some clarification for dummies.

Problem: I had the stock 4.4.2 on my 16gb d802. I have Rooted it, but when trying to install twrp via Flashify, "recover mode" wasn't successful, i tried "boot mode". (stupid I know) Now, when turning on phone, there is LG screen and then a black screen (or maybe something written on upper left corner, cannot see left half of the screen but its getting fixed tonight) I can get into the Download mode though.

I only have access to a mac. No friends or anything around, so I will ask at a place for a favour to use their pc tomorrow but I will probably have limited time. I just want to make sure everything is ready on a usb beforehand. That's why I want to ask some questions now. I plan to use the KDZ method.

* Does it need to be a specific Windows OS? Or will any (like xp/7/8/..) be fine?

* I understand that I have to connect the phone to the computer via a USB 2.0 only? Any other important details like this?

* Choosing the firmware file: My exact country version is not there. Can I download any European .kdz file which is 16gb and not operator specific? I have no idea like what are the difference between d80210a, d80210b... Asking this, so that I can have some right and relevant kdz files ready in my USB. I will not have the chance to download later.

* Apart from the .kdz file, I download the drivers, flash tool and C++ runtime if necessary. No other programmes, official LG apps or anything?

* And then after running the flash tool programme, I choose the relevant kdz file. How about the drivers? Where are they supposed to be located?

Thanks a lot if anyone could give some info in advance.
[G2 General] hyelton:
1. Windows 7 Recommended but does work on 8/10

2.Yes as USB 3.0 wont work. Along with using the original cable that came with the phone.

3.Yes, as long as it matches your model. A=Jelly Bean B=KitKat C=Lollipop

4.You don't want Offical LG apps. Everything needed is in the OP nothing is left out :)

5. You install the drivers that are located in the OP.

Welcome to XDA :)

But pretty much everything needed is all stated in the OP :)

Provide US an update :)

Stuck at Setup Wizard Verizon to T-Mobile

Like the title says. Every thing worked like a champ! I wanted to install the 39A bootstack from here:

http://xdaforums.com/verizon-g2/development/vs980-resources-bootstacks-unofficial-t3050777

So I went to stock and here I am. I can't get past the Setup Wizard with my TMobile Sim ..says I have to call Verizon for activation

Thanks in advance
[G2 General] hyelton:
Awesome :). You shouldn't need a Verizon sim in it. There should be a skip or use wifi button.
[G2 General] Carpender:
Thanks for the quick response :)

No sir the only option is Emergency Call with a picture of the Sim x Phone picture ...with the saying "Sorry, were having trouble activating your phone. Please call (877)807-4646 from another phone to activate your 4G LTE service.
[G2 General] hyelton:
Never seen that before on newer Verizon phones. Try resetting and take the sim out. Worked just fine for me a few months ago on another Verizon G2 with no sim in it.
[G2 General] Carpender:
Ok will do and I'll get back to you..Thanks for the help

Update: Turns out I downloaded the wrong file. I downloaded VS980S11A_01 which like you said was a earlier one. Downloaded VS98026A_00 and BAM!!! up and running.

Thanks for the help!!
[G2 General] yijit:
Thank you very much :) Already sorted out. Today I have found an old style internetcafe with old pcs and which hadn't blocked installing apps/drivers and voila :) Went on pretty easy in 5-10 mins!

I had self-changed my broken screen yesterday :victory: and USB 3.0 has indeed not worked on Macbook w/ Bootcamp Windows 10.

But does this USB 3.0 problem only affect the Download Mode, or is it a problem in general, like can you not root the phone via 3.0?

Btw I now have Android 4.2.2 on my phone though and it does not update automatically. I am afraid to break it again so I plan to use stock 4.4.2, and only root it for some apps. Any suggestions welcome.

Anyway, thanks again for help and everything :) Really appreciated
[G2 General] hyelton:
Anything to do with download mode and USB 3.0 won't work. Other normal things like transferring files etc will work fine on USB 3.0.

Sorry no suggestions on root. I don't keep up with it too much to keep up with lol. I keep up with the stock stuff for the G2,G3,G4, and so on. not a big fan of custom things besides light tweaks or running a stock international rom/firmware.

Glad you got it working :)

Your welcome :)
[G2 General] yijit:
Haha yeah makes sense, I'll follow the same mentality :) But do you think it is normal that I cannot receive the updates to the stock ROM? Or would it arrive to my phone eventually? I have UK 4.2.2 and it says it is the latest OS, which is not the case apparently.
[G2 General] hyelton:
So you have. D802 then correct? Why not just flash straight kitktat or lollipop then?

Also try performing a reset to see LG is mixed when it comes to OTA updates at times.
[G2 General] yijit:
Yeah, D802 :) Thought the kdz file I chose from the list (d80210b) was Kitkat but I think I was wrong.

Can I flash without a usb 2.0 PC from now on? Otherwise I will sort it out later, the internet cafe was in another city! :) at least I have a working phone now :) Sorry if being off-topic btw.
[G2 General] hyelton:
10b is jelly bean. I explain this after your first post I think anyway.

10x JellyBean

20x KitKat

30x Lollipop.

For the G2 Anyway.

No you cannot as it requires download mode and it'll only work with USB 2.0. MacBooks don't have USB 2.0? Strange. But it's never recommend to use a Macbook anyway. You don't know anyone with a PC? I have 100 of them in my spare room, granted there old but still someone has to have a PC around haha.

But at least you do have a working phone though
[G2 General] yijit:
Aw I took the "B" at the end was Kitkat. Haha yeah I should've kept an old spare laptop. Maybe I will have PC's around when the uni starts after new years :) Thanks a lot again :)

lg g2 d802

Hello there.I have an LG G2 D802 16GB version and after i replaced my cracked screen with a new one my phone has a major problem.The problem is this: despite the LG logo being displayed,when the phone tries to go to the home screen the following message appears"Device will turn off".Of course after this message is displayed the phone turns off.I made a factory data reset thinking it would solve it,but no it did not.Now despite the fact i lost all of my data,the phone keeps displaying the message when the welcome logo appears as it has been now factory reseted. I have never rooted the ROM or installed anything else,and was using android 4.4.2 before that problem occurred.Also i cannot enter recovery mode,download mode.I tried connecting it to my PC but it did not appear anywhere on the device manager,plus the LG logo was lagging when the phone was connected to the PC.I had sent the phone to a technician(Not a LG official,he just has a shop where he fixes various phones)and he told me that i possibly damaged the motherboard during the new LCD screen installation,which i doubt as i was EXTREMELY careful.I have searched everywhere on the internet(trust me i did)and i haven't come up with a solution yet.The phone was bought in Greece on summer of 2014 so it's not locked to any network(Verizon,sprint,t-mobile,etc...)

Please halp, bless you.

[MENTION=2607037]hyelton[/MENTION] can I just say thank you for all the help that you provide and do. I am having trouble with my D801 (T-Mobile Variant) and I have tried using the kdz method, but it is not working for some strange reason. (It may be because I installed Cyanogenmod 13 latest nightly. But I am trying to do the tot version, but there is no tot file for the D801. Any help would be great thank you.

Another side question not sure if relevant I am going back to stock to see if my GPS not working is a hardware or software problem. Thanks again!

I did it silly question, the zip file listed had to be extracted which was the tot file. Thanks!

Restoring back to stock(I am currently on ZVH) made the gps on my LS980 somewhat functional again. Still a little slow to lock on but works when it finally does.

I flashed the latest kitkat tot for my d800. I'm activated on at&t but i havent got the lollipop ota yet. Does it just take a while to come through? I tried factory reset a few times. Its been about 8 hours since the last factoty reset and it still says the phone is up to date.
[G2 General] hyelton:
So you have an AT&T sim in the phone right? And on your my account your imei is registered? Like you didn't just now switch to the phone ?
[G2 General] kierkegaardesque:
Correct, I have an AT&T sim in the phone and it is the same one that has been in there for the last 6 months. I am assuming IMEI is registered as I have been using the phone for 6 months with this sim.

No much else to other than keep performing resets till it works. LG is the worst with carrier branded phones

Thanks for your help. I'll continue with the resets. So is the update supposed to show up immediately? Like if I reset and the first thing I do is try to update, it should be there?

While using the kdz method the lg flash tool after pressing get started shows disconnected please try to connect and then retry

While my mobile was in download mode

[G2 General] hyelton:
Can you explain a little more about the "error" if it's server connection that's normal that's supposed to come up and your not supposed to click anything As its actually flashing

Not sure what you mean by get modem in device manager? Only thing you need is lge com or lge serial com port under commucation ports in device manager. If your running Windows 8/10 they maybe hidden.
[G2 General] Karim Ahmad:
Sorry I just found out that I have no download mode. After the first transition screen instead of firmware update it went to Fastboot mode where I have '

Also how to show those hidden menu in Windows 8 PLEASE
[G2 General] John Cantrell:
I have the Verizon VS980. I was on crdroid marshmellow and somehow my son while playing minecraft froze the entire system. No worries I'll just power off wait a bit and power up, after powering back up nothing but random ghost screen presses and no way out, used twrp to reflash but didn't fix the issue, so Grrr I'll just kdz or tot back to earlier version (kdz'd to 27a) which went smoothly ( or so I thought ) upon the reboot same ghost presses taking it into accessibility mode. after finally getting it out of accessibility mode the ghost presses are really bad. Did a factory reset and no luck. So I went and tot'd back to 26a with the exact same issues. My phone screen is off it'll just come on and show five or six presses on the screen etc.... open random apps, random swipes that hang between screens etc.... plugged into computer and verizon assistant updated software to 3AA - same issues, factory reset, same issues. Used vz assistant to "repair" phone. Same thing. I'm letting the phone sit off for awhile then reboot and let it sit for awhile to see if that might clear it. Pain in the butt as my wife just used my upgrade to upgrade her phone because she broke her screen beyond repair so I now am unavailable for upgrade till the end of April. If it doesn't fix it guess I'll just have to go to verizon and let them try to reflash it since it says everything is official and on the 3AA software....
[G2 General] hyelton:
Seems to be a hardware issue. Verizon will do the same exact what you've already done. Maybe they'll give you a replacement hopefully.
[G2 General] John Cantrell:
Well I guess if I take it to VZ and they get the same results they'll have to do something. I'll just dig my heels in and tell them quite frankly it's their upgrade that messed up the phone ( I had refused to take the 3AA upgrade before ) and I will not pay for service on a non-working phone.
