Refurbished/Fake LG G3 Check Now Available

[WORKED FOR ME ON STOCK KK WITH STOCK RECOVERY]
This guide will prepare you well to battle against all the Fake/Refurbished LG G3's present in the Market.
I recently upgraded to LG G3 D855 and was faced with alarming numbers of Refurbs.
In this guide, i'll explain each and every step that I produced to avoid any refurbished or Fake G3
Q.What the heck is 'Refurbished'?
Well, you already know its basic meaning but i'll ponder upon the Refurbished G3 D855.
Refurbished G3's typically show D855 in the 'About Screen' and even you can put the Hidden Menu Code i.e 3845#*855#. Almost all assume that its an ORIGINAL/GENUINE D855. In most cases, that's not true lad :crying:. All D855 Refurbs got D850/VS985/LS990 mobo and thus you will not be able to mess with it or even install a Custom ROM on it. Above all, it's a Fake one Dude! That's not what you paid for.
Now if you follow each and every step carefully, even if you are a noob, you'll eventually end up with a Genuine D855 :good:
Things you need BEFORE buying..
1. Laptop/PC
2. Attached adb files within this thread.
3. Data Cable.
Instructions:
1. Enable Android Debugging by hoping into Developers Options.
2.Go to Setting->General->About->Software Info->Build Number [Write it down as you'll need this Later!]
3.Change the Connection mode to MTP.
4.After extracting the attached folder, Right Click on it WHILE holding the Shift key. Now click on "Open command Window here" and type the following commands.
adb devices
[Now you'll see an Authentication Box on your device, check trust this computer and hit OK]
Now Type,
adb reboot recovery
Here comes the moment of truth
At top of the recovery screen you'll either see D850/VS985/LS990 or your Build Number. It's quite obvious that if your Build Number appears, you got a Genuine D855. If you get some other crap written there then all my apologies with you mate!
PS: I didn't include the IMEI check as all these Refurb phones come with Original D855 IMEI. Never Trust the IMEI check under no circumstances!
Troubleshooting:
Q.'Device Not found' Error after following the set of adb commands?
Make sure after typing 'adb devices' you get the 'Android USB Debugging' Dialog on your device, else you can try reconnecting the cable or even using another port on your Laptop/PC.
Q.My Phone booted into TWRP/CWM?
Well, that happened with a friend of mine and now it's quite tricky to check if it's a D855 or any other. You can try making a backup of EFS (or any other partiton) and reboot your device after that. Now browse into TWRP folder and hop into Backups folder. If you see a LGD850xxxxx (or anything like LGVS985xxxx etc) then it's a refurb set else if you see LGD855xxxxx, you can calm down now as it's a D855.
Good Luck, Hit 'Thanks' if this saved your a**[emoji14]

I got mine refurbished, but it's genuine! Thanks for the guide, saved my butt, haha!

Try restarting device or your pc

So, basically, you just entered recovery mode, yes? Can't we just use hardware button combinations (power vol down) to enter recovery mode instead? Does it had any differences?
I am planning to buy a second-hand G3 and I need a LOT of fake checks to test...

Technically, Yes! You just gotta enter Recovery Mode. I didn't check if Hardware Buttons work or not on Stock KK Recovery.
Can you post the Results? I'll update the guide then.

Exactly, Hardware Button combo would let to a Factory reset. The only solution is to access Recovery via adb.

LG G3 D855. Can't upgrade KK to MM
Hi,
I recently bought a "LG G3 D855 32GB 4G LTE Unlocked" from amazon which came with Android KK. Everything looked genuine. But for the life of me, I just couldn't upgrade to MM neither with LGUP or LG Flash Tool. I checked everything. TWICE ! Made sure I had the right USB drivers, run the tools as Administrator, redownloaded the kdz file a number of times. Nothing. So I suspected it might be either fake or refurbished. I tried what was suggested here and I couldn't get to what I was expecting to be the recovery mode. The phone just factory resets and boots up, or if I use adb shell as advised it just reboots. What am I missing ?
Thanks.

You can get Lollipop OTA upgrade to make sure you have got the genuine version if the lollipop OTA works on your device.
and
Also have you downloaded the correct drivers, have proper USB cable and booted phone into download mode to apply KDZ update. If it still don't work then give a try to tot method.

Well the procedure i produced worked on various genuine/fake G3's. Hardware Button combo would definitely let to a factory reset so *The Only* way to access Recovery is via adb shell and make sure you type the whole command i.e "adb reboot recovery"

For now, I have sent the phone back to amazon. Hopefully I'll be getting a replacement in a few days. I'll try again and report back here. Can you confirm if i don't have to root the phone and install a custom recovery tool before running "adb reboot recovery" ?
Thanks,

I'm confused
I was under the impression that refurbished phones were the exact same thing except they have to go through more checks after they have been fixed. What am I missing?

Guidance required: H815T TOT antirollback version is smaller than device version

I got my lg G4 h815T with H815t10H installed on it, few days back.
OTA and LG Bridge
Checked OTA update and it stated that device is updated. But LG Bridge showed H815T20D is available. So i started the update process. But it stopped with an error at 80% approx. It gave a retry option.
But the error persisted.
LgUP
Then i downloaded the H815T20D manually and tried LGUP. It gives
Error code:0x2000, TOT antirollback version is smaller than device version
Click to expand...
Click to collapse
Then i downloaded H815T10H, thinking may be if this gets flashed then i may flash 20D. But it still gives the same error.
LGFlashTOOL2014
Then i tried flashing H815T10H using LGFlashTOOL2014 . It started the update process (going into LG User support tool). Completed 100%.
Phone restarted and BLANK. no nothing. no life.
QFIL
I then used qualcomm 9008 method and flashed 991 recovery.
TOT
====
Download TOT file "LGH815AT-00-V10h". Tried flasing through tot method. LGFlashToolv1.8 can read imei and serial but process stops at 9% with an error.
Currently
=======
No LG logo
Can get into recovery mode.
LGUP and LG support tool recognize device in Download mode as H815T10H
When tried to flash kdz using LGUP getting same error.

Sounds like you may not actually have an H815 but maybe a Sprint or Verizon or other mode.

Did you check your IMEI online to see if it shows the same model as well?
Only real way is to take the phone apart.

Here is IMEI report, it says LGH815T.
New thing is operator is OPTUS while i got carrier free. May be Optus rom will work. Lets try it.
Update
====================================
I already have tried H815T20d_00_0120.kdz for OPTUS H815T same error given by LGUP i.e. TOT antirollback version is smaller than device.
Infact this was the rom downloaded by LgBridge.
Any other suggestions.

Since you have already flashed the sprint firehose file with QFIL you may want to check out the thread by @steadfasterX below. He is working on a BL unlock which may be able to revive your phone to some sort of working order but has some limitations as it is still in testing.

Thanks for replying
Alright opened my mobile and surprise is that mainboard is EAZ66585501_H810_MAIN_1.0
so it is H810 not a H815t and surely a refurb
Now the question is how to flash a H810 rom.
currently it can be restored in bulk mode using Ls991 recovery, then if i apply tot method to flash H810 tot it gives an error saying "991 cross to 810".
Please suggest.

Still i can share the whole info [as it is on back of the mobile] with you guys in hope of further info:

Please remove your imei info from your post. Its not good to expose that.
Your serial looks odd by the way.. Usually it starts with 5xx, 6xx or 7xx.. So I assume it is the 665
Try this:
Pull out battery disconnect USB cable to your pc.
Insert battery and wait 5 sec. Then press vol down and while keeping it pressed plugin the USB cable to the pc. After 10 sec latest you hopefully see the fastboot screen.
If not :
Do you have Linux or a live cd like FWUL?
What I currently try to find out is if you're screwed or not. That means when you have used the qfil method it is likely happened that your device now is converted to a ls991 because of the qfil files you flashed!!!!
That's why I warn everywhere to not use the qfil method until you know about the results.
Let us know how it goes.

Strange brick on Axon 7 A2017G after rollback to MM

Dear Friends,
I had this problem...
Buy this phone with MM6.0.1 and after a week decide to update to N 7 with OTA. Process was clear and fast...
after another week and affording a lot of issues with clock, bluetooth, etc.. i decide to rollback to MM6.0.1
There's the problem... phone boots and do the presentation of images like it wants to enter, but stucks in the image of AXON...
Only can enter in a strange recovery, without shelters... only START, Restart Bootloader, Recovery mode(that does nothing), Power OFF, and Boot to FFBM
Anyone has a minimal idea that was happen? Don't want to wait an eternity to send back to china and wait to reapir, if anyone have a solution.
Images are an example of issue, you can see but no can do anything in the screens.
Thanks for your kindly cooperation folks!!!

Version of MM is important! Was it on V1.0.0B10 or V1.0.0B11? If older, it was too old to go N and ZTE say do updates via SD card, not OTA. There are tools to recover it but I'm not up on them as mine is stock and carefully updated to B09 N so I will leave it to others well informed to explain recovery methods.

That's fastboot mode. No idea why it is booting to that screen. I assume you are locked so miflash is probably the easiest way to fix.

Lol no, you have to put your phone in EDL mode. But maybe you can get to the recovery and flash another version first.
If you have an SD card, do this:
Turn the phone off, wait around 5 seconds and hold Volume Up and Power. It should boot into the recovery. You need to have the SD card inserted, with the B11 rollback package. select Install through sd card and install it.
If you don't have one, you need to get in EDL mode.
Connect the USB to the PC but not the phone.
Turn the phone off, wait around 5 seconds, then hold Volume Up and Volume Down (NOT power) and insert the USB cable on the phone. After that go to Device Manager and check that the phone appears (as Qualcomm HS-USB QDLoader 9008, in 'Ports (COM & LPT)'). Download an A2017G B11 FULL EDL package and flash it with miflash.
P.S. Is it an A2017G? If it is not, just use the packages from the model you have. I just read that 'send back to china' bit.

Here's the support page on the ZTE Australia website, I read this before doing any updates and have had a trouble free run to B09 N. Mine was on older firmware than B10MM when I purchased too.
http://www.ztemobiles.com.au/feature_AXON7.htm
The information will apply to any A2017G on older firmware. The latest shipments are now coming with B11 MM so they can go straight to B09 N.
I unboxed mine, turned on with B10MM update on an SD and updated it, then updated to B04. Didn't use it before it was on Nougat.

So my V35 is stuck in Fastboot mode

The phone (AT&T version) failed installing the Fi Android 9 update (following the instructions for LGUP modded) and after that the phone is now stuck in fastboot mode and can't enter download mode with the volume up and power button combo.
Am I out of luck or is there a way back to a functional phone?

Yep, that did work at first when I was able to attempt the first flash in LGUP, but after it crashed the phone was stuck in Fastboot and would default back to fastboot even when I held the buttons for download mode. And now, the phone is stuck in Firmware Update mode. :crying:

Update: Phone has been fixed, got in contact with (motogvasyag) from XDA who helped me get back up and running. $20 well spent.

Same fastboot loop problem for my V35 after LGUP flashing with Android Pie. Did you send your phone to that guy or was the phone fixed remotely?

Hi there, the phone was fixed remotely via Teamviewer. He just had me install Octoplus pro, USB Network Gate and then a patched version of LGUP.

At&t v35 unlocked wont work on verizon

Any way to make the att v35 work on verizon? It should have the hardware is it a firmware update ? I'm a bit noon level at all this custom Rom stuff. I need some directions if I am able to do something please

From my understanding, even flashing an AT&T model to USA unlocked firmware does NOT carrier unlock the phone. You have to get the carrier unlock code from AT&T.

Flashing to NAO carrier unlocked should give it CDMA bands, if V35 can be Frankenstein'ed like V30.

It's probably carrier unlocked, but hasn't been flashed to NAO carrier unlocked firmware so it still has the AT&T V35 bands.

You need to use Dev Patched LGUP to cross flash to NAO carrier unlocked firmware.
You do NOT need to root. We do not have any custom ROMs for V35.
You just need the Dev Patched LGUP from one of the other threads and cross flash to NAO (North American Open Market) firmware over your AT&T V35 model.

It's all fairly easy. Most people breeze right through this. But if you have any problems, go through this list:
* Make sure you in download mode BEFORE opening the patched LGUP file.
This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,
* Try different USB port,
* Try different USB cable,
* Try different computer.
* Reinstall LG mobile drivers on your PC.
* Reinstall dev patched LGUP again.
* Reboot the computer.
If you ask for help, that's the list of items we are going to give you anyway.

You're welcome!
For future updates, you'll flash future NAO KDZ releases via this same Dev Patched LGUP -- but next time you can use "Upgrade" mode instead of "Refurbish". It's like a manual OTA and will save your data.

@ChazzMatt,
That's what I love about DEV patched LGUP--It let's you bend the rules and do some things that would normally require root access, specifically:
--DUMPing of any partition, allowing for data backup and recovery, even on encrypted partitions, since you can also dump the encrypt partition.
--Cross flashing .kdz's from other variants utilizing the same hardware
and
--Flashing only specific partitions from a given .kdz
and I definitely agree that CHIPERASE and BOARD DL are to be avoided--
The most useful options besides REFURBISH and UPGRADE are DUMP and possibly PARTITION DL
Sorry for inserting my two cents into your thread.

Hi.All.I have cross flashed LG v40 Hong Kong version Rom Android 9 with the Korean Android 10 using lgup.
THE Rom was installed but I lost radio.no signal. So then on the advice of a friend I flashed partition dl modem a and modem b from a European version 9.and when the phone rebooted it shows security warnings and says all slots are unbeatable. Any way to put oh in fastboot mode so that lgup can identify.Any easy way out.thx

First of all, these are LG V35 forums but that's fine I guess since the V35 and V40 are same exact when it comes to how to unbrick. You can't mix Android 9 and 10 like that, no wonder you got bricked. At this point, even if somehow you get into LG UP, make sure you don't use any options in LG UP or any other tool that you don't know about. Lot of people tend to use options like 'chiperase' thinking it will fix the phone but they make matters worse and permanently loose their IMEI and EFS partition info.
For LG UP you need download mode, not fastboot mode. Are you able to get to download mode by holding volume up button while the phone is turned off and by plugging in the USB cable that is connected to the computer? I think you should still be able to get into download mode even if phone can't boot but If you can't get into download mode this way and can't boot into android, the next option will be using QFIL/QPST by putting phone into EDL mode. Since the process of unbricking will be same for both V35 and V40 phones, I will briefly guide you here for others with V35 to see this info but if you need further help, it would be best to post in LG V40 forums. The QFIL/QPST folder and V35 engineering bootloader from link below work for both V35 and V40 but rest of files such as firehose and actual partition files are different between the two models.
First go to the LG V40 unlock guide post here: https://forum.xda-developers.com/lg-v40/how-to/unlock-lg-v40-via-9008-root-t-mobile-t4042207
and download QPST, firehose and v35eng bootloader files attached to the above post and thank the OP. You can just follow that guide as if you want to unlock bootloader but basically you are going to put phone in EDL mode using that guide so you can run QFIL and access partition table using partition manager and flash the files necessary for download mode. All you need is bootloader and and laf partitions to get into download mode which are abl_a or abl_b (based on which slot you are booting from, slot a or b), and laf_a or laf_b. Important to note that laf_a and laf_b are same exact files actually, same is true for abl_a and abl_b. I am uploading the files for V40 on Mega as these were too large for XDA but if anyone needs them for V35 just post here and me or someone else can upload them:
https://mega.nz/folder/o2xEnCSb#W5icT64hASwKk67G9IngEQ
MD5s: abl_a: 3a9e506523e92b6a242af2e1cb5987fd, abl_b: 3a9e506523e92b6a242af2e1cb5987fd, laf_a: cf9edf4748f768cfa3c88ca362ff36b3, laf_b: cf9edf4748f768cfa3c88ca362ff36b3
After you download attached files, flash abl_a file to abl_a partition, then abl_b file to abl_b partition, flash laf_a file to laf_a partition and laf_b file to laf_b partition. You can use Xsavi's guide to put the phone in EDL mode, start partition manager, then use the option load image and flash the files to their respective partitions. I don't remember if these are from Oreo or Pie as I don't own V40 anymore but I think for unbricking purposes it shouldn't matter as you are going to flash a whole KDZ on top of these anyways. Once done, turn phone off, start LG UP on your PC, hold volume up button while you attach the USB cable to the phone and it should put the phone in download mode. Use partition DL and flash full KDZ either Oreo or Pie first before you try going to Android 10, best would be flashing Oreo first as some people have had problems going straight to Pie or Android 10.

You don't need to hold power button. Phone needs to be turned off. Hold volume up and plug in usb cable. Since you are in bootloop, keep holding volume up button (don't hold power button) and plug usb cable in. Once the bootloop cycle restarts it should go in download mode, just don't let go of volume up button until in download mode. If you still can't enter download mode, you are pretty much out of options and have to use EDL mode as i explained above to unbrick your phone.

Thanks a lot. Yes i am holdingvolume up button and inserting usb c but it doesnt go into dowmload mode. But edl mode also requires to boot phone or can it work in a bootloop
---------- Post added at 10:50 AM ---------- Previous post was at 10:35 AM ----------
Anothet thing i want to add is that the ph is going in factory reset and even erases all user data.ive even done that. So that means that the ph isnt bricked? But even after that it doesnt go in DL mode

Yeah if you can't enter download mode then in my opinion using QFil and EDL mode is probably the only way to go. You need to read the unlock guide by Xsavi, that i linked earlier: https://forum.xda-developers.com/lg-v40/how-to/unlock-lg-v40-via-9008-root-t-mobile-t4042207
You are not required to boot the phone in order to enter EDL mode but it does require lot of patience as you have to hold volume down and power button until phone screen turns off suddenly to reboot, rapidly start pressing volume up key while still holding the volume down and power button. While you do this phone needs to be plugged in with usb cable and you have to have QFIL window open. Once the phone enters EDL mode, the screen will be dark and blank, but it is detected in QFIL window, you know that you are in EDL 9008 mode.
Unbricking your phone will require a lot of reading, patience, and making sure you understand what you are doing. It seems complicated and overwhelming but trust me when you have all the files setup and are ready to go, the whole process takes like 5 minutes and is not so hard. Again, the key is reading the guides and steps multiple times before you proceed so you know exactly what you are doing.

Thanks im doing reading will getur expert advice soon

Also, factory reset will not help at this point because part of your rom is android 9 and other part is android 10. Erasing userdata and cache (factory reset) in itself will not fix that. What i don't understand though is that just flashing modem_a and modem_b from Android 9 should still allow you to enter download mode since you didn't alter bootloader or the laf partitions. In my opinion the phone should still be able to enter download mode even if it is bootlooping unless more changes were made to phone where bootloader and/or laf partitions were also altered. In any case, it doesn't matter anymore I guess.
Edit: Great, good luck, hope you get it unbricked!

Yes i didnt alter anything apart from the modem partitions thats it and dl mode unavailable.thats the issue.so does this necessarily mean that booting into qfil is the ultimate solution

Can you please tell me that i dont want bootloader unlocked just want dl mode..so for this do i have to follow the whole guide or just part of it to enter edl mode...pls enlighten

Hi sir. I have bootlted into qualcom 9008 mode used qfil and flashed the required partitions which were successfully done. But the phone still cannot boot into download mode . after i flashed i simply exit the qfil and. Piwer down he phone but it still does the same as before and cant get into download mode
.did i miss something
