Lg g7 thinq (lg710pm) to (g710ulm10g)

[War Destroyer]

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.

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.

New user (Canada)... decided to share my experience.

Stumble across ebay deal for those LG G7 G710PM converted to ULM phone and couldn't resist.
Bought 4 for all family home and abroad. (100$ to 150$ depend on the wear) Best deal ever. I can't figure out what is the big deal and importance of OTA updates.
Since my son asked for Netflix one of the phones runs on Verizon Pie "G710VM20e_03_1205.kdz" now.
Smooth re-flash on LGUP Dualmode with "partition dll" select all and second re-flash with "refurbished" option.
GPay and Netflix works. GSM Signal normal. LTE data normal but only by manual APN setting. WiFi calling tried to register without success. Could not care less.
Second phone on Pie "G710ULM20e_00_NAO_US_OP_1010.kdz" no GPay and Netflix although SafetyNet looks better: request success but response failed. Don't know how to check if wifi call works.
The last two on original Oreo LM-G710ULM (V10b-LAO-COM)
I may actually keep original LM-G710ULM (V10b-LAO-COM) since the benchmark test on AnTuTu I have ran gives better performance 34000. The same test on G710ULM20e_00_NAO_US_OP_1010.kdz gives 32000 and on Verizon Pie "G710VM20e_03_1205.kdz" 30000.
If anyone have any Idea how to properly test the performance will gladly run new tests.

Recent update:
I have successfully re-flashed my converted LG G7 G710PM (LM-G710ULM (V10b-LAO-COM)) to the latest Canadian android 10 (G710AWM30b_00_OPEN_CA_OP_0605.kdz).
Direct flash from android 8 to 10 with LGUP Dual - Partition DL - All
Everything works fine. SafetyNet - PASS all the checks.

I also done the same to my G710ULM, the phone works fine for few months but the SN is missing now.
