LG UP always on unknown. Every guide.

I have a Sprint LGG710PM that was flashed to LG710ulm (Android 8)

I am trying to flash a newer .kdz on it (G710ULM20f_00_NAO_US_OP_0218.kdz)
I have tried all the guides in this thread step by step. (The 1st guide is a little ambiguous since it tells instructions about programs that exist in multiple folders, but doesn't clarify which folder you should executing in) I've even tried using uppercut from older guides as well.

My phone always shows up as unknown in LG UP.

I really wanna update and retain this phone but am running short on my 30 day return window. Never flashed phones but have hacked consoles and this appears easier 'cept i dont' know whats wrong here.

Please help.

So, i follows the steps but I chose the partition DL method and didn’t select checkboxes in the pop up.

This gave me the “your device has failed a routine safety check”

I need to have this fixed and have the Verizon rom flashed (as I have read it works the best) and losing patience lol.

Any anyone help me resolve this as a service?

Please PM me. Thank you

Has anyone encountered a problem with voice/call roaming suddenly not working?

I have 2 G7's that were flashed from PM to ULM, both running 20f version and one of them will not roam at all since couple days ago. The other one is still fine.

Network reset, factory reset, nothing fixed it.

FYI, I first reflashed it with Android 8 file and the roaming worked right away. Reflashed it again with 20f file and it's still working.
No idea what caused it but re-flash is the fix.

New version available for the crossflashed - I recently updated to G710EM30f_00_OPEN_EU_OP_1124 (Dutch european version).

I choosed upgrade option iirc, but it did refurbish flash, so I had to restore all my data. Imho 4g improved for German Telekom and as it is an european version, not as much "bloatware" - more privacy according to gdpr compared to asian ROMs.

My reception improved by the european stated above, but I don't know what's best for NY / your provider. I use German Telekom with

LTE Band 3 around 1.8 GHz
LTE Band 1 around 2.1 GHz
LTE Band 7 around 2.6 GHz
LTE Band 8 around 900 MHz
LTE Band 20 around 800 MHz

BR and happy new year

I have an unlocked G710PM from Sprint but I am now on T-Mobile. Reception sucks. From reading this thread it appears if i flash to G710TM it will brick. Is there any version I can flash a G710PM to that will improve the reception?

Few weeks ago i got a LG G7 “UNLOCKED” on ebay, the phone had a sticker where it said model “LGG710PM”, the bad news i was stuck with a FIRMWARE LM-G710ULM (V10b-LAO-COM) MAY 2018. I tried updating the phone via OTA or LGBridge and i had no luck. So i looked online for the correct KDZ file for the LGG710PM and also no luck, So what i did is look for a G710ULM KDZ, but the only one the i could find was the G710ULM10G_00 (https://www.mylgphones.com/lg-g7-thinq-project-fi-stock-firmware-g710ulm10g.html) . So after searching online and watching some videos on youtube if this could work, i found a youtuber video (MAXLEE) he change a FIRMWARE of sprint to a Canadian FIRMWARE and it work he did it on a LG G6. So what i did is try it on MY G7 model LGG710PM“ the only thing is that on the G7 there's a few more steps to do:

1) Download G710ULM10G_00 KDZ file
https://www.mylgphones.com/lg-g7-thinq-project-fi-stock-firmware-g710ulm10g.html

2) Download LGUP and install (make sure to use this link for download and follow instructions, like this you don't get an error when
you insert the KDZ file and hit START).
https://mega.nz/#!kCpHBaia!xZmico6MYL1T07ffuc8z6cCbs5oU4pKEz5VG-AwfvV0

A) Make sure you don't have LGBrige installed, if so UNINSTALL and delete any folder of LGBridge after you have uninstalled
(C:\Program Files (x86)\LG Electronics)

B) Download the LGUP zip file and unzip, if you don't have the drivers install lgdrives(The file is inside the folder LGUP-LG G7 ThinQ).
After that install “LGUP_Install_Ver_1_14_3 (1).msi “ file.
a>


C) After installing LGUP you must go to C:\Program Files (x86)\LG Electronics\LGUP and copy the first three files(CODEFIRE, LOG,
model) from the UNZIPED FILE from step B.

D) Go to file “model” (C:\Program Files (x86)\LG Electronics\LGUP\model) then go to file “common”....go to step “E” don't close the
window….

E) Go to the UNZIP FOLDER, go to file WindowsLGFirmwareExtract-1.2.6.1-Release. Run “WindowsLGFirmwareExtract.exe” and select
the KDZ file you downloaded, then make sure you
check on “LGUPc.dll. EXTRACT KDZ.

F) A file “LGUPc.dll” will be created, Copy that file into the folder “common”...... you should had left that window open from step “D”. Rename the actual “LGUP_Common.dll” to
“LGUP_CommonDDD.dll” and “LGUPc.dll” to “LGUP_Common.dll” and then deltate the “LGUP_CommonDDD.dll”.

Open LGUP...put your phone in download mode... select the KDZ file you downloaded from step “1” and in PROCESS select REFURBISH…. Then click START.
Youre a life saver. Many thanks man been trying to unbrick my phone for 3 days an your guide got me past the last wall i was slamming my head against haha. **** yeah! thank you!

Hello! Someone tried to flash locked G710PM in the Canadian version G710AVM?

Same here. Bought sprint unlocked phone preinstalled with G710ULM10g from ebay and upgraded to Android Pie G710ULM20e October patch with LGUP tool manually.

Now I realized the fastboot is gone with Android Pie. Does there any way I can root this phone?
fastboot mode only available in the Android 8 or any euro version.

    I encouraged myself to go to vm, for those who want to go from ulm to vrz, follow these steps:

    1) Download the firmware VRZ (update 2019-03-14) https://downloads.lg-firmwares.com/get/a42fdbf7f618577f38368c9786dee3e3/G710VM10i_02_0211.kdz
    2) Download the DUAL LGUP https://drive.google.com/drive/folders/1MJ5sjpzlZyRVoqUhwsNkAo_FHNbaMNy5
    3) uninstall the LGUP software or any other lg software
    4) Install the drivers lg http://tool.cdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
    5) Reinstall LGUP, at the end they will choose setdev.bat to create the DLL.
    6) When they are flashing, they will use the partition dll and select everything.
    7) The device will start but will not pass the animation, it must be flashed anew with the option of refurbish.
    8) Now it will start, it will restart the logo and give you the welcome screen.

    Greetings!!! ... and I hope it serves you ;)

    I bought sprint unlocked phone preinstalled with G710ULM10g from ebay for T-Mobile network .Upgraded to Android Pie G710ULM20d June patch 3 months ago with LGUP tool manually and today updated again to October patch G710ULM20e.Every time there is a new patch you have to repeat the same process.

    1) Download kdz file from this site
    lg-firmwares.com/downloads-file/21135/G710ULM20e_00_NAO_US_OP_1010

    Note:- It's not allowing me to post hyperlinks ,just add secure protocol before links i.e https://
    I realized all links are in the first post.Just download above firmware.
    LGUP Tool Flashing Image
    LG Support Tool Current Version After Update




    ---------- Post added at 11:05 AM ---------- Previous post was at 10:09 AM ----------

    @EPayan Yes you can.See the link to LGUP tool image I posted.The reason why I posted that image is to point the correct versions.I did flashing with different versions of LGUP tools and DLL's finally I found the correct versions that worked with my phone.I came across the same error you mentioned with different version of DLL.Just make sure you have correct version and place rom file in LGUP tool directory ,after everything is in order disconnect phone and switch phone to download mode and reconnect and flash (I wish I came across this first post before I wasted valuable time )

    Hi. I also bought a G7ULM but I think it's a PM flashed. I am stuck on Oreo 8.0 with July Security Patch and 710ULM10f firmware.

    Can I use this method to get manually update to Pie?
    Any risk of Brick?

    Thanks.

    ***************************EDIT ************************
    I am trying but say Missing .DLL and i dont know what else to do.

    Wel I just follow this intruction, thank to @Jafet Guadamuz, Post #156, Pag. 16

    1) Download the firmware ULM20e (update 2019-11-14) --HERE-- (ULM Firmware its the free unlocked version for USA, No bloatware at all)
    2) Download the DUAL LGUP https://mega.nz/#!Jww2GIAa!efSwLp3vCl1ajANCutYGWn6qimypN5KMzW1xS3M0YSY **Link fixed**
    3) uninstall any lg software (Very Important!!!)
    4) Install the drivers lg https://mega.nz/#!FwxjiYQa!qZAFZNNNyFFuPrzDQp0C2KW_CmoQaaoY7hq-mFrvuAM
    5) install LGUP, at the end they will choose setdev.bat usin Right click and "execute as an administrator" to create the DLL. (This step its very important, I was getting DLL missing error with the main post method, this work fine for me)
    ----Open LGUPD and do not close it.
    ----Now Turn Off the movil and put it in "Download Mode", Press Volme (+) and Conect it to PC via USB (LGUP should now "See" the Movil
    6) On LGUP Flashing Screen, use the partition dll and select "Refurbished" and Select the .KDZ file that you al ready downloaded
    7) Now it will start, it will restart the logo and give you the welcome screen. in my case, phone reboot normally Twice,after second reboot its ready to wizard configuration!!!!

    Remember, i Bouth a Sprint Movil with ULM firmware and I was stuck with no Update on Android Oreo 8.0 FW 710ULM10f and July 2018 Security Patch, Now I am on Android Pie 9, Clean FW 710ULM20e with 1st October 2019 Security patch!!!!
    Still no S/N and I dont know if Google Pay Works because I dont use it.
    Thank you and I hope to help!!!!!

    I decided to flash Verizon. Followed the steps in the original post. At the last step I got an error "Not support cross model download G710ULM to G710VM" I wonder if I downloaded the wrong kdz. I followed the link for Verizon and there were two kdz files. I might have downloaded the "VRS" region instead of the "VRZ" region (it had a slightly newer date). would that have been my problem?

    Download this to your desktop https://drive.google.com/drive/folders/1MJ5sjpzlZyRVoqUhwsNkAo_FHNbaMNy5?usp=sharing Right click on the setdev.bat and run as administrator it will auto put dll for you then open lgup connect phone and press repartition dl then press start then box to select all press ok few seconds later press yes after wards press reset phone when the phone boots up

    Hi, I updated to the Verizon firmware and here are the good news:
    - shortly after I received a couple of updates.
    - Google pay seems to be working (it allowed me to add a card, but I did not try using it, but I believe it is OK)

    The bad:
    - I am using a non-Verizon SIM and I get the warning The SIM card is not from Verizon. It will show up again after every reboot
    - The phone did not accept the APN settings. I had to manually add them.
    - Another warning trying to set up Wi-Fi calling, but it does not work (probably non Verizon SIM)
    - Bloatware: It doesn't seem to be a lot. I didn't try to remove them yet

    - Others
    - When I added the SIM the phone informed it was a non-Verizon so it switched to the Global mode. Not sure what if the difference
    - I service menu *#546368#*710# does not work on this firmware. The ##77647226710 is accepted but it asks for the Service code and 000000 is not accepted. I was looking for the menu to test LTE bands. I had done a list from the ULM version and wanted to compare, but I cannot access on this version.
