And you have an D855 32GB model correct? Did you try flashing a newer firmware? If you have a D855 why not use the kdz method?
[G3 General] Oac95:
Hi guys I'm stuck I bought LG G3 back side sticker with imei shows LG D855 other's on back also show D855. Rom is 4.4.2 and shows phone software version as D85510n, hardware model is LG D855 but when i go in recovery it says on top LS990Zv6.

Can anyone help me here what exactly I bought [emoji14] I'm sure it's a refurb but if i want stock MM which one should I go with or if other then stock Roms which one will work for me. Attached screen shots for reference any more information required plz let me know. Help would be highy appriciated.

Regards.

Ps: sorry I cannot upload pictures as it says I do not have permission to attach a file.
[G3 General] hyelton:
If you bought it online I’d suggest returning it. LS models are sprint models. Flashing anything other than you have now will either brick or you’d have to return to sprint firmware then the phone would only work on sprint.
[G3 General] Oac95:
Thanks I bought it from a shop, I did checked one other thread where guy had same issue and he flashed Fulmic I think I'm not sure of name right now and it was working fine for him. I'll share the thread in some time.

Can tou please confirm if it will have the same Camera which comes I original it will be a different one as quality is not very good though it is 13MP.

Thanks anyway for the info. :)...

Hi there, i would really like your help, i've looked at the versions there up for grab on storagecow, but there WAY too many version for me to figure out which one i need. I have a simple LG G3 D855 32GB that i want to have English as it's language. (no branding or anything else on the phone)

Can't start the hardware code 10 error

I am flashing lg g3 but when I plug the usb and go to download mode,then in device manager there is an error saying: The device cannot start (Error code 10). What should I do, my lg g3 stays in download mode for about 1 minute then the screen goes black. Help please.
[G3 General] hyelton:
What item in device manager says error code 10?? MTP is supposed to show that. As long as the com port shows it’s fine that’s all you need. What’s your reason for needing to flash it? Does the device shut off randomly or reboot? If so that sounds like a battery issue which could be affecting download mode.
[G3 General] GenAsh:
Yes the MTP shows that. Recently green screen of death appears on my lg g3, and so I decided to flash it. The problem here is also with the COM Port, the COM Port shows LG G3 Verizon when I connect it, then after a minute it disappears and the mobile screen shuts off. Is this can be a battery issue? My battery is fine.
[G3 General] hyelton:
MTP is supposed to show that so that’s ignored. It could be a battery issue but if you where getting the green screen of death that’s a hardware failure most likely which cannot be resolved by flashing it. There is some hope your seeing the com port (as long as you don’t see the 9008 thing) but if your phone is shutting off without doing anything after going into download mode not much I can help there :(
[G3 General] xHOLDx:
I have tired the method #3 but quite seems to get it to work. It is always either stuck at 6% and fail or I would not even get to the process to flash which gives me an error of "Open Packet Error No: 0x80000001
[G3 General] detru1990:
Hi, I tried to fresh upgrade to MM yesterday. After the process was completed, my phone completely died. The screen will not turn on, it stays black. No LED notification lights. But when I plug the USB to my computer, my computer makes a sound like it detects the phone. Is there a fix for my black screen?

Edit: Nvm. Found the answer. It's hard bricked now
[G3 General] hyelton:
Only time a hard brick can occur Is if you flashed wrong model firmware or attempted to downgrade a certain model.
[G3 General] detru1990:
So, what happened was that I was given a jailbreak phone, which I cannot make phone calls. So I reset to stock(LGD850AT-01-V10d-310-410-JUN-19-2014+0.tot), but it has Android version 4.4.0. I then upgrade to MM Global version (D85530B_Global.kdz) , which was successful, but it doesn't read my T-Mobile Sim. I then search through your thread and found T-Mobile MM (D85130d_00_0404.kdz), which then I download and tried to wipe Upgrade. LGUP informed me that was it complete, but when I check my phone, it went black, cannot be turned on and no indication from LED Notification light

My phone model is LG G3 D850, which belongs to ATT

I flashed it to stock with : LGD850AT-01-V10d-310-410-JUN-19-2014+0.tot

I then upgrade android global to : D85530B_Global.kdz

And then wipe upgrade to : D85130d_00_0404.kdz

Is there a way to fix this or hard brick it is the only way? I tried taking the battery out, removed the Sim card. Presses Volume up and Power, pressed volume down and power.

By the way, thank you for responding and for the information
[G3 General] hyelton:
You can ONLY flash D850 firmware if you have a D850. Flashing the D855 firmware most likely erased your EFS and without backup turned it into a wifi only device.

And then flashing the T-Mobile firmware thats going to cause an instant brick.

Only fix is to replace the motherboard.

Why where you flashing other models? That cannot be done.
[G3 General] detru1990:
Oh, I see. That was my first time flashing a smart phone, as it's a backup phone anyways. But thank you for all the info. 1 more question though, since it's been bricked, can I try to unbrick it or the only way to fix it is to replace the motherboard?

https://xdaforums.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359

UPDATE: Just for anyone out there who has the same problem. I found a way to unbrick using this method. Lucky for me, I dont have to open up my phone. I can go into reset mode now.

BootLoop woes

I have D850, I can't remember if it came with lollipop or mm but I downgraded to KitKat when I got it, then rooted and have run Fulmics and most recently CleanRom 2.8, but it started having issues with app crashing and I thought maybe I would just take it back to stock but was a little confused on whether to use method #2 or #3 and ended up trying both.... :eek: I finally got the LGD850AT-01-V10d-310-410-JUN-19-2014+0.tot file to take but am now in boot loop, I have used both tools, multiple usb ports, a different battery.... at one point I got MiniOS to load... a few times I got phone to boot and started going through setup then it would reboot, should I just try the hammer next!?! lol or, is there something else I should try before I move on? I'm considering the next step of shorting the motherboard or whatever but not super confident on that

also, thanks in advance Hyelton!!! I have read so much of this 500+ thread and can't believe the continued support for this device, you're a badass.
[G3 General] hyelton:
In mini os you need to choose reset or factory reset and it should work. If your having reboot issues that’s a common battery issue with ageing G3s.

And your very welcome :). I hope to eventually get another G3 at one point lol
[G3 General] kehrberger:
Dang, I have flashed about 7 more times and can't get mini OS to load again, but both batteries I have are a lil old, so just ordered a new one, Hopefully that will work!

Should I be using LG Flashtool or LGUP?
[G3 General] Fangthane420:
Since apparently those of us who are on 4CA and want to root are SOL, I thought maybe re-flashing the stock Verizon MM firmware would help restore a bit of stability. I followed the instructions from post #2 and just can't seem to get it to work. It keeps giving me a "Model Information Check FAIL." Any ideas what may be going on? Ideally, I'd originally hoped to flash a custom ROM on this thing, but seeing as that's apparently never gonna happen, it would be great if I could at least get the re-flash to work and hopefully it'll become a little less laggy and prone to overheating.
[G3 General] greerdd:
I getting the same error trying to flash a KDZ to my LG Stylo 2. I'm on Windows 7 with "SP2" installed. Any suggestions how to resolve it? Thanks
[G3 General] hyelton:
It’s a computer issue.

Also if you have “sp2” installed you have a pirate copy of some sort. There’s no such thing as a windows 7 SP2
[G3 General] uxairmalik:
there is no way to resolve this issue.cause its random.you just got to try on different computer different window versions.and somehow it will work on its own.
[G3 General] greerdd:
That's why "SP2" in my message was in quotes. Some (many?) people refer to the kb3125574 update as "SP2" for simplicity, since it was a massive update.

---------- Post added at 03:21 AM ---------- Previous post was at 03:20 AM ----------

Thanks, I'll see what I can do.

Update: Was able to bypass "Check Milky info.." issue by downgrading LG Flash Tool to the version 1.8.1. Now after "Check Milky info.." it says "Verifying BIN CRC" and then the titlebar of the small window associate with COM41 turns yellow and says "READY". The message inside the window says "Waiting for connection" and that's how it stays even when the phone is connected to the PC. Tried several times disconnecting/connecting the phone yet LG flash tool does not see it and still waiting for connection. The phone's driver is mapped to port COM41.

Any ideas? What driver do you use? LGE Adroid USB Serial Port? LGE AndroidNet Serial USB Port? Something else?

Thanks
[G3 General] uxairmalik:
Samething happens to me.

I always use the drivers that are posted by OP.

There is no way to get past this.

You have to try it over several computers
[G3 General] hyelton:
So you manually mapped the com port to com41 in device manager?

Also your using a usb 2.0 port correct? USB 3.0 won’t work. And phone in download mode?

[G3 General] greerdd:
I meant driver model, LG mobile driver installs several of them, see the enclosed pic. When I connect the phone Windows simply shows it as "Android" under "Other devices". So I need to manually assign LGE driver to be used for the Android device.

So, which driver model do you use: LGE Android platform USB serial port? LGE AndroidNet platform SB serial port? Something else?
[G3 General] hyelton:
Neither. You install the driver using the driver installer. Don’t change the driver that way it’ll just screw things up
[G3 General] greerdd:
Yes, manually mapped it the phone driver port to COM41, the phone is connected to a USB2 port and is in download mode.

There is a strange thing though, see inclosed pics: the LG flash tool includes a USBView utility or something like that. That utility shows the connected phone with yellow exclamation sign, like there is something is wrong but I'm not sure what it is (see pics). Thanks
[G3 General] greerdd:
Double post
[G3 General] hyelton:
No clue on that tool. Only thing you need is what you see in device manager and it looks like it should
[G3 General] greerdd:
I don't change the LG mobile driver but after the driver is installed and the phone is connected to the PC, Windows just shows the phone as Android device and doesn't know what driver to load for it, see the enclosed pic. So I have to assign the LG driver to the Android device otherwise Windows won't load it when the phone is connected to the PC. During that proces I need to select a specific model for the driver to hangle: LGE Android Platform USB Serial port, LGE AndroidNet Platform USB Serial port or whatever (see the second pic). This is what my previous question was about. Thanks
[G3 General] hyelton:
You just need the COM port. The other drivers are supposed to show up like that, they’re not needed when in download mode

Hi,

I've flashed a file D85530n_00_0816.kdz via LG Flash Tool 2014.

After flashing, the phone said that Android is upgrading and try to install application. Then it restarted itself and now It is on bootloop. I tried to factory reset it but didn't worked.

Does anyone have a suggestion for that? Can It be a hardware failure?

Thanks.

Depends. What was your reason for flashing? Did you have an issue before? You did factory reset the phone correct?

Hey guys, hope somebody gona be able to help me and hope my Lg G3 is salvable. I'm pretty sure I bricked it. Enjoy my story

Recently somebody give me a LG G3 D852 (Bell variante). When I got it, it was in 6.0. Since I wanted to root it, I tried to downgrade it to lollipop.

- At first, I followed the TOT method. But I simply just can't run LGUP on my main computer. I can't even install it. A computer problem, I don't really remember the error code. Don't really know why. Anyway, since it wasn't working I jumped to the LG Flash Tool method.

- While trying the KDZ Method with LG Flash Tool, I never been able to make it work. EVery time, while my phone is connected to my computer, in download mode, LF Flash Tool alway get stuck at arround 4% and tell me something like it wasn't able to connect to the phone and the only thing I can do is retry endlessly. Now, I abandon this methode to go back to LGUP with another computer.

- Now I tried to follow every steps of the TOT methode, but on another computer. Which seem to be working. I took the firmware TOT file from that "storagecow" website. I took the Bell_D852 file for canadian variant. Once the process been done, the phone restarted and now it's been stuck forever on a little android robot and a blue progress bar screen. I did tried to wait but after an hour I don't think it's normal.

- Since then, I can't do anything. The phone is stuck, I can go in download mode without problem, but LGUP doesn't recognize the phone anymore. It does detect the phone but doesn't want to do anything with it. LG Flash tool as never been working for me so doesn't help me either. Also I can't enter in factory reset mode anymore (which doesn't really surprise me).

If anybody could help me that would be much appreciated. Thanks in advance, have a nice day!
[G3 General] hyelton:
Sorry for the late reply. Been extremely busy the past few weeks.

LG flash tool kdz method wouldn’t of worked at all if the device was running MM 6.0. Only the tot method and LGUP works if the device was running MM. do you see anything unusual in device manager when the phone is connected in download mode? Like something with 9008 in the name?
[G3 General] spletko.b:
Currently running stock MM 6.0 V30o-EUR-XX. I am trying to downgrade so I can root and flash another ROM. I have tried CSE flash with LG Flash Tool 2014 tool. It didnt work... also tried 2015 (updated with pictures) TOT Method! and it said: "model information check fail" in LG FlashTool 1.8.1.1023 for LG g3 d855?
[G3 General] hyelton:
Your running MM. You have to use LGUP. Flash tool is not supposed to work.
[G3 General] AliasGprime:
Hey, I'm sorry about the late reply, christmas time over, now able to get back to this.

So as for the device manager, no I don't see anything unusual. My phone is there as "LGE Mobile USB Serial Port (COM41)" while in download mode. Still not recognized by LGUP.

EDIT: got something new in my tries, I happen to get LGUP working, but just once, the process get stuck at 6% and I got en communication error. Now it doesn't recognize the phone anymore. Got an "Unknow Model" error.

EDIT 2 : ok, I think I got something. I can try LGUP only once and I have to restart my PC to make LGUP work again. Could it be because of wrong tot files? On the storagecow website, there's only 2 tot files for the d852 canadian model version, neither of those seem to work and now once I get my 6% error, I clicked on "click here to continue" and LGUP is telling me "The input file [D852] is not appropriate for this device model [] BinVersion []"
[G3 General] SnowFuhrer:
What carrier?
[G3 General] AliasGprime:
Virgin Mobile, which I tought the Bell one would do the trick.
[G3 General] SnowFuhrer:
Yeah, bell should work. I always use Telus ones on my Koodo d852. Try downloading the latest one from lg firmware in kdz format. It also depends on what mode you flash it.
[G3 General] AliasGprime:
Can I use KDZ files with LGUP? As I use it, it seem I can only use tot files.

EDIT : I've tried others KDZ method (LG Flash tool, ...), falshing MM bell firmware, and nothing seem to be working, Every software keep giving me a phone connexion error what ever I do.
[G3 General] SnowFuhrer:
Yes I have only used kdz and never tried tot files. You just need to edit it when you search for a file.

I did, I tried on differents usb ports, different cables, even on my second computer, not working on it either. I get something different on my second computer though. LGUP, on my second computer, won't even detect which model the phone is and I can't do anything with it. I've the possibility to try on a third computer if that could help...

I cant install a v20 version on my G3

Hi there

Thank you for your great post.

for the past two days, I've trying to downgrade my LG G3, my purpose is to install a custom rom (Lineage).

I have a G3 32 Gig with android 6. As I understand, I need to first downgrade it in order to root it.

At first, its software version was V30e but I manage to install a new version on it (now its V30b-Global-YT). I did that because I read somewhere the one click root wont work in V30e.

Now, I understand that it needs to be on Lollipop for rooting to work. So I'm trying to install a v20 version on my device.

I've tried these versions: D85510B_00, D85520A_00, D85520F, D85520h_00, D85520n_00, D85521a_00, D85530b_00_0812, D85620B_00.

however, as I mentioned earlier, only the installation of D85530b_00_0812 was successful. For this reason I know that I can install a new firmware, but I cant find the right version.

PS. I bought my phone in Iran, its 32 gig and I'm using Windows 10.

I also used LG Flash Tool 2014 for the installation.

Thank you in advance for your help.
[G3 General] sudman:
Sorry not sure I understand but are you saying you rename the KDZ file to a TOT file and then flash. I have the same issue in that UG UP only seems to be looking for TOT files and there's no option to change it KDZ files.

*Edit* Dont worry I've used the V10e EUR TOT file and that's got me back to stock from latest Lineage build. Geez this phone is so slow on stock firmware compared to the Linage build. Will be very sad to see it go though as it almost the perfect size & shape for my hands. :(
[G3 General] SnowFuhrer:
Ya, there is a way, maybe delete .tot from the line and type in .kdz? I have done it before, but it is a pain.
[G3 General] :
Which stock firmware??

Hello,

I have an LG G3 D855 32GB running Android 5.0 v20c-SEA-xx , with the following info

<suffix>ASEAOP</suffix>

<buyer>SEA</buyer>

<file_name>D85530b_00_0812.kdz</file_name> <-- I'm guessing this was the initial firmware

<cs_em_flag>N</cs_em_flag>

<chip_type>EG</chip_type>

I would like to downgrade to kitkat firmware so I can install Bumpd! twrp, but I don't know which firmware to download. I tried looking up my suffix but didn't find any info. :( I'm downgrading to kitkat because I read that Bumpd! twrp is compatible only with kitkat's bootloader.

I think the firmware I want would be the Singapore version because of SEA buyer entry and the current v20c-SEA-xx android OS? Even if I guessed right, there's two for Singapore on OP's download site: D85510B_00 and D85521a_00 - I'm not sure which one...

I'm afraid of bricking my phone if I choose the wrong firmware, so any help would be greatly appreciated!

- LG FlashTool show a "Failed PreviousLoad()"

Is there a way to downgrade a D855 to something that can be rooted then TWRP ?

You need the right .dll file for your model.
