G3 d850 ATT Model - Factory Model Check ERROR!!

Hi!

I recently purchased an LG G3 d850 and I want to root and install twrp on it. However, I accidentally updated to 6.0 and from what i understand you can't get root while on 6.0, so I'm attempting to downgrade to lollipop so I can root.

However, after attempting to downgrade, I get a download fail error. The program says:

Model Information Check FAIL!

0000000

Factory Model Check ERROR!!

I am using a USB 2.0 port and COM port number 41. I've also tried UPGRADE DL and Board DL, but no dice. :/

Do I have to use LGUP to downgrade because I am on marshmellow or what am I doing wrong?
[G3 General] mysteryjeans:
I am trying to flash D85630B_00_0521.kdz using LGFlashTool 2014, but keep getting error at S/W update on Windows 7, Windows 10, USB 2.0, different systems.

Is there anyway to do it or can we convert KDZ to TOT?
[G3 General] hyelton:
That's because you must use LGUP. Flash tools won't work once your MM
[G3 General] hyelton:
What is the error? And where you running MM before? If so you must use LGUP.
[G3 General] mysteryjeans:
Actual I brick my phone to 9008, and recovered with with F400K tot with boarddiagv2.99a, then used LGUP tool to flash complete TOT with F400K.dll.

Now I tried flashing D85620A_00, D85620B_00 & D85630B_00... neither worked!! its typical error of flash tool "Disconnect & remove battery ...."

Edit: I also tried to extract KDZ and used LGUP8974.dll & D85630b00.dz extracted files in LGUP tools, but it gives "Failed Previousload()" like others complain
[G3 General] hyelton:
But why are you using flash tools to flash? Why not use LGUP 59 flash the kdz.
[G3 General] mysteryjeans:
Am I missing something? I only know these two method you mentioned on post?? can you guide me how?
[G3 General] hyelton:
I'm confused. There are 3 methods here. And you said you already used LGUP to flash the F400 tot. Why not use LGUP to flash the kdz files your flashing??
[G3 General] mysteryjeans:
As far as I understand there is only one method for KDZ using "LG Flash Tool 2014" and another is TOT method for LGUP, what is the third method?

---------- Post added at 01:05 AM ---------- Previous post was at 12:42 AM ----------

Man that desired a second post!!! :eek:

I had bricked my phone trying to get KDZ & then went to No download/No fastboot mode with corrupt system. So I short testpoint to get into 9008 mode flashed with F400 TOT (somehow i know that it will boot my device since i ported cm 12.1).

New tool was detecting my device as unknown, so I first flash all images via fastboot extracted from D85630B_00 except SYSTEM, boot to download mode, now its was detected as F400K10g. All was left is to choose D85630B_00 & selected refurbished on guts and done.

NOW it is on optimizing apps.

I was old visitor of this thread never thought you have added another method.....! :silly::silly:
[G3 General] hyelton:
Im glad you got it working.

The 3rd method is LGUP. LGUP flashes both TOT and KDZ files.
[G3 General] Zzchechi:
You right, I was under the assumption LGUP only worked for d855 - I just downgraded to kitkat though, thanks!
[G3 General] vi777x:
Help!

Okay, so i used this method once, when I upgraded manually to 6.0 from lollipop.

I had marsh flashed, also had twrp and did backups once in a while.

Also I've mounted a custom kernel (xceed) like a month ago.

Yesterday I noticed a weird bug, that annoyed me. I coudn't click the middle of the screen it was going up or down.

I was annoyed by that so I backed up and the bug was still there.

I thought maybe a full reset will help and I used the lgup method(re-doing it)

After it finished it rebooted me into twrp.

I clicked reboot into system and it brought the twrp back.

"This is weird' I thought. Well let's back up.

[G3 General] hyelton:
When using LGUP you chose refurbish right?
[G3 General] vi777x:
Yes, + closed and opened it.

sir i got mine upgraded to marshmallow 6.0 i found some issues. the mobile data network symbols is not showing up anymore (H+,H,E and 4g) but i can still access the internet. is this normal sir??
[G3 General] Mif425:
I have read a number of different threads, but I can't seem to get a clear response on if there is a current downgrade path for the D851 (T-Mobile) from MM 6.0. My goal is to downgrade, root, and get onto Fulmics. Any insight? Has anyone had Success with LGUP on the D851?
[G3 General] hyelton:
No you cannot downgrade due to Anti roll back sadly. And if flash tool / lgup Doesn't stop you you would hard brick your device.
[G3 General] Mif425:
Thanks for the reply. Guess I am stuck with this stock G3 then :(
[G3 General] johnmbailey:
I am seeing the LG Logo bootloop, after reflashing the KDZ on a US990. There was some strange behavior after rooting the phone, so i used the Flashtool 2014 to restore stock KDZ. The phone will allow going partially thru the setup, and then it will randomly reboot. Is there some remnant of Bump or ?? that is not restored with a flash of the factory KDZ? I have tried to flash a couple different versions of the KDZ, all with the same result. I can partially omplete the new phone setup of each Android verssion restored, and then it will randomly reboot and then it is stuck in a bootloop never getting the LG / USCellular logo. ARe there some different settings i should use to flash the KDZ? I do have some TWRP backups , but the phone no longer goes into TWRP Recovery mode.
[G3 General] hyelton:
Your choosing CSE flash correct?
[G3 General] vi777x:
Yay!

I progresed a bit!

I formated data and now i can use my storage.

*restoring*

Succes!

Rebooting to system...

Lg logo

1 frame of text, couldn't read it.

Back to twrp.

Also, LGUP doesn't see my phone, but my pc does.

Any ideas?

EDIT

Found the reason!

I forced refrubish with kdz

Can I flash the tot or kdz file through twrp?
[G3 General] johnmbailey:
Yes. with settings of

Type: CDMA,

PhoneMode: Diag

Select one of the US990 KDZ

>US990Z04_01

>US99010c_00

>US99021a_00

Select CSE Flash

I also found a couple other KDZ files that i downloaded last night

>US Cellular US99020a_24 - Flashes the LG logo in 2-3 second intervals a couple times, then Android upgrade box, then returns to LG logo 3 or so times, then Green android, then LG and then the upgrade box, then sticks in LG logo in 2-3 second interval. Before this flash, i had tried the Factory reset recovery as someone had said it might stop the boot loop after flashing the KDZ.

>US990Z04_01 - I hve not tried this one yet, as I figure that it is not getting better so i better wait for direction.

Are there other settings that might do a more complete Wipe? I have used the LG Flash tool on other G3 phones, but the US990 does not have a TOT file available that I can locate.
[G3 General] haru3173:
I'm having the same problem as you but I'm on d850. I flashed d850 kk tot and everything went well until i went ahead and use 1 - click root. Everything installed corretcly even the root but all of a sudden I'm getting bootloop as above. I reflashed again to stock but still getting bootloop
[G3 General] hyelton:
So you where using upgrade? Your not supposed to use that. Some have bricked using that. You always use refurbish that wipes.

No you cannot. Kdz files are factory from LG and tot files cannot be flashed either. You must use a PC and LGUP
[G3 General] hyelton:
Wait.. How do you have the same problem? You should be flashing tot files not kdz like the user you quoted.

On flash tools you tried board_dl option correct?
[G3 General] hyelton:
Have you tried using LGUP and using the refurbish option?
[G3 General] haru3173:
I flashed tot file and followed every instruction on post 2. Everything was working fine at first and the problem began when i tried to root using the 1 click root. Even after reflashing again to stock the problem still persist. I was actually able to boot past the bootloop and using it to normal but when i turn it off again or pull the battery the problem will come back again its just a matter of waiting maybe 10-30 bootloops and i can use the phone again.

---------- Post added at 06:20 PM ---------- Previous post was at 06:08 PM ----------

I also tried board_dl but it got to around 80% and got download error something about mini os and it booted to aat mini os
[G3 General] hyelton:
If your phone is working fine till you reboot it that sounds like a hardware or battery issue.

It's supposed to fail after 80%. After that it's done flashing rest is rebooting. When it boots into mini os you select reset/restart
[G3 General] vi777x:
I rorced refrubish, not upgrade. - when choosing file for refrubish deleted the "*.tot" and wrote in "*.kdz", so it could see the kdz file.

UPDATE

Managed to unbrick the phone!

Found the vol. up + usb trick and used it with LGUP using a

.tot

file and refurbish option. (thanks to him)

Went to 4.4.2 (lol)

While auto updating found an interesting thread: [here]
[G3 General] johnmbailey:
Not until i saw your post. I just Flashed the latest US99023a_06_0401.kdz, with the Refurbish option. The phone rebooted, showed the Green android briefly, Android update box briefly, and then got stuck in the 2-3 second LG boot loop. Should i try one of the older KDZ files, such as

>US990Z04_01

>US99010c_00

>US99021a_00

I I cant avoid the bootloop in any way other than starting the phone in download mode, so that somewhat limits me on options.
[G3 General] mkhabbab:
I successfully flashed my ATT D850 to KK stock rom using the .tot and .dll method and my phone is having bootloop now. I did factory reset but issue is still there. I tried other batteries but still having the bootloop. Previously it was stock lollipop on my phone and it was working fine, apart from the usual battery-pull-then-start issue. Can someone send me the link to KDZ file for lollipop stock for D850, i do not want to flash through recovery.
[G3 General] hyelton:
There's no kdz files for the D850. It's tot method only.. And it which the latest tot file is KitKat.

Did you choose board_dl on the dll/tot selection screen before flashing?
[G3 General] rsg55371:
What is the Factory Reset Status 2 and how to I Fix it?
[G3 General] hyelton:
Reflash by choosing board_dl on the tot selection screen
[G3 General] johnmbailey:
So are there no other options for restoring the phone with the available KDZ files?

IF the phone can't be recovered with available tools, then can i somehow edit the build properties file so that i can flash with the TOT file of the LS990? I have heard that the system board is very similar between US990 / AS990 / LS990 phones, so how can i flash using the method below, which requires replacing the current build property file?

[G3 General] TheSanteriAT:
I accidentally ran the newer FlashTool before doing any of the other steps and unplugged my phone... Now I can't reach Download Mode or anything, as I don't have a ROM or a recovery installed on the device at all. Is there any ways to fix it?
[G3 General] hyelton:
What do you mean you ran flash tool before any other steps? There's no other steps other than running flash tool and making sure you flash the correct model.
[G3 General] TheSanteriAT:
I mean that when I ran the Flashtool it asked me to login. This was the 2015 TOT method I was using. After failing to login a couple times it just closed and I was left with the phone showing me 3% progress. Then I unplugged my device and now it won't boot into Download Mode anymore
[G3 General] hyelton:
The only tools for going back to stock are all in the OP. I'm really not sure why you can't flash back to stock, something has got to be stopping it. You can risk installing an LS990 Sprint version but that'll be at your own risk and sprint version will he a pain to get working GSM wise.
[G3 General] hyelton:
Flash tool can't start flashing until you've selected the tot and DLL file.. Flash tool doesn't ask for a login. (As long as you copied the megalock.dll into the flash tool folder.
[G3 General] TheSanteriAT:
Yeah. I don't see how the device got amything, because I couldn't properly use the Flashtool, but it somehow did. I found a guide to use a Qualcomm software to try and repair the phone. This far no success...
[G3 General] hyelton:
Yeah there's no possible way at all. Only way was it you had something else running in the background. Does it show up something 9008 in device manager while plugged in?
[G3 General] TheSanteriAT:
It shows QHSUSB_BULK
[G3 General] hyelton:
Something would of had to been running on your computer to cause that. That's really strange. Flash tool wouldn't of had a way. Yeah you'll have to try and get the method you tried above working.
[G3 General] TheSanteriAT:
I don't really know how I'm supposed to install the right drivers. I've already installed both 64bit and 32bit and neither work. It still shows me QHSUSB and nothing in ports. Windows 10 says I already have correct drivers, but seemingly my PC tries to use wrong ones and I can't find the right ones anywhere
[G3 General] hyelton:
If if shows QHSUSB the drivers are working.
[G3 General] TheSanteriAT:
No, the drivers were not working correctly. To get the 9008 thingy to show in ports I had to remove Microsoft's driver and make sure Qualcomm's driver was working. Now I got it to show
[G3 General] mkhabbab:
Well I had selected upgrade_dl. Today i flashed again but selected board_dl as per your suggestion and did the factory reset too. Now bootloop is gone but my phone would restart around once every 30 seconds. Sometimes during initial setup sometimes during configuring the wifi sometimes restart in dormant state too. So it is still unusable. Do you think it is hardware related or software?
[G3 General] hyelton:
That would most definitely be hardware or battery
[G3 General] mkhabbab:
Hmm but when i bought this phone, it was stock lollipop and had very few restarts around twice a day only. It was same hardware and same battery.
[G3 General] hyelton:
Remember hardware failures can happen. How long ago was that?

Try and see if it boots while connected to a charger.
[G3 General] mkhabbab:
It was around 1 month ago. It restarts even when connected to charger (USB connected to laptop) which confirms that it is hardware issue i guess?

I was advised to buy a new battery which i did so but problem was not resolved. Then i tried few custom rom's but problem was worsened. I am comfortable if it is hardware issue but he problem is, the repair technician insists it is not hardware problem. Strange thing.
[G3 General] johnmbailey:
I downloaded the latest KDZ for the US990 again, and this time it worked. Turns out that the latest available KDZ is 5.0.1 Android. I guess the original download was corrupt, and it just did not like the other older versions for some reason. Now i just need to find a way to get GSM working on the phone. You suggest that flashing to LS990 makes it more difficult to get GSM working, so what would you suggest starting with The US990 with 5.0.1? I plan to root next using King Root, which worked initially, but am open to suggestions on a more flexible root without the extra unnecessary apps built in. Is IORoot the best alternative?.
[G3 General] hyelton:
Glad you finally got it back!

Sorry no clue when it comes to rooting. I only keep up with things stock and I've never owned that exact model. So it doesn't work with a sim? Try dailing *#*#4636#*#* select phone info, scroll down, and select GSM/WDCMA/LTE or try WCDMA only.
[G3 General] johnmbailey:
I just tried this and when i selected the 'Phone information' i receive a message 'This application does not work on this device' I can see the general phone information under this window, but it goes away when i select'OK'.

Thats Good....

just download the stock v30b flashable zip ...(thread link below)

flash it until done..... boot ...... and just plug to your PC ...no need to go to download mode...choose Upgrade (in my case i cant use 'refurbish' option.... coz that option wont allow you to choose kdz formats.... only tot....) then starts..... makes some coffee.... or just watch ur tv ... it takes only 10mins on me

AT&T G3 (model D850) on MM and want to get rid of all AT&T stuff

Hi all,

I may have missed the whole point and I'm sorry if I did... but my goal is to get rid of all the AT&T stuff. I live in Canada and I'm trying to flash my device with a stock LG ROM using this method : http://xdaforums.com/showpost.php?p=64624324&postcount=2

I have an AT&T G3 (model D850) on MM. When I get to step #14, I need to unplug and replug my device so the process could start. When I do, it does start, but fail at 0% with an error "Model Information Check Fail!".

After few tries, I continu to read, found that since I'm on MM I need to use LGUP method, but LGUP seems not suitable for my D850 device...

If it is the right method though, would I use only a TOT file or both KDZ and TOT (but I did not fond any KDZ for a D850 model...)?

Thanks for your help!
[G3 General] hyelton:
flashing the stock D850 firmware HAS all the AT&T bloatware. You cannot flash other model firmware on the device.

Yes you must use LGUP. LGUP works with every LG android device. And it's your only way to flashing firmwares once MM. The D850 is only an AT&T model and is tot method only.
[G3 General] gnatnog:
My D850 has the screen flicker problem, and most likely is going to have to be repaired. I am running fulmics 6.1 so need to completely unroot. I understand that I need to use LGUP, but the LGUP post states it isn't for my variant. Searching the thread it looks like it should work, but I'm not sure which file to download to give to the tool as my understanding D850 doesn't use kdz files. Can anyone point me in the right direction?
[G3 General] hyelton:
LGUP is for all lg android devices. You would download the Kitkat tot in the OP. LGUP flashes both tot and kdz files.

You first may want to flash a stock based non customized custom rom in twrp first. Flashing back to stock doesn't work well with customized Roms.
[G3 General] eso259:
i ended up replacing the MB with D855

but i have the stock 5.0 "V20i", i know its battery sucking android version for G3

so i want to downgrade to 4.4.2 stock, i have this KDZ file LG G3 (D855) Android4.4.2 10O

if i followed the KDZ methodm will it work ?

thanks you for your dedication for the topic and time

is the LGUP method work for f400 korean series?

because i've tried using LG Flashtool 2014 and it's always goes to "has stopped working" everytime i try to open flashtool

also has installed the vcredit
[G3 General] hyelton:
What do you mean has stopped working? If it's the tool itself it would be something on the computer that's causing the program to not work. Yes LGUP works with every lg android device. If you were running MM LGUP is the only program you can use.
[G3 General] a.live:
I mean like for unknown reasons accidentally the program has stopped working,

yeah maybe there's something wrong in my computer..

Even still in android KK?

Sorry for noob questions ? just handled this phone in a month

[G3 General] geek-x:
Hi guys, I had an issue where I did an OTA update of my D855 from 4.4.4 to 5.0, the upgrade worked fine but after some days, I started to get bootloops on my phone. I then decided to wipe and flash a marshmallow KDZ with LGUP, cause other methods weren't working for me.

I followed all the steps with precision, and I was able to get the G3 booted up to the part where you get a dialog "Android is Upgrading" and optimizing apps, after everything was done, I saw the LG Setup screen, but on trying to touch the phone, it went back in a bootloop again. Where it didn't get past the LG splash screen, please help.
[G3 General] hyelton:
The other methods won't work with MM when messing with MM you have to use LGUP. When you flashed you chose refurbish right?

Also where did you buy your G3 ? It could be a faked model if you started having issues after updating.
