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.

***************************EDIT 2***************************

**************************SOLVED**************************

Wel I just follow this intruction, thank to [MENTION=6233651]Jafet Guadamuz[/MENTION], 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!!!!!

Kindly reminder: If a PM hardware upgrade to a pie ULM software, the PM phone will lost the fastboot mode.

You can get Android 9 here, but the obvious rules apply. You won't get google pay and netflix also believes it to be rooted. I've successfully flashed using LGUP 1.4

Hi.

I ended up buying same Sprint model with ULM firmware and I was stuck with no Update on Android Oreo 8.0 FW 710ULM10f and July 2018 Security Patch. I debating keeping the phone or flash Pie as above instructions . IT does not show any serial number, can this be activated on postpaid plan?
[LG G7 ThinQ  Guides, News, & Discussion] kukuteku:
In my country, Yes. I got from eBay a G710PM with a ULM Oreo Firmware crossflashed, I follow the step showed above and Flashed Pie via LG Up manually. I use a Postpaid plan Sim (Altice/Orange) and everything works fine.

I dont know if Volte or Wifi Call works because don't have thats option in my country.

I was able to download LG g7 DLL file from google search and my phone(g710ulm10g was sprint lg710pm) was detected by LGUP as g710ulm10g on COM 24. I have the downloaded G710ULM20e_00_NAO_US_OP_1010.kdz. It is ready to go for flash but kind of worried that it would brick the phone or may break the network unlock feature?? Please help...
[LG G7 ThinQ  Guides, News, & Discussion] kukuteku:
Just follow the instrutions -HERE- . Connect the phone on Download mode, if LGUP "see" the movil everything should be fine.

I already Update 2 LG G7, no problem at all. about network, My phone came Unlocked Network, flash do not affect Network configuration. You can use any Sim/Company.

good luck

Hello! Someone tried to flash locked G710PM in the Canadian version G710AVM?
[LG G7 ThinQ  Guides, News, & Discussion] mattonxda:
Any idea why I keep getting the error: _checkCrossDL Fail.

Tried restarting the whole process from scratch a few times and still the same thing.
[LG G7 ThinQ  Guides, News, & Discussion] kukuteku:
I think " _checkCrossDL Fail." Its showed when you open LGUPD and the soft cannot "see" the phone.

Did you follow step by step?

"Step No.5- install LGUP, at the end they will choose setdev.bat usin Right click and "execute as an administrator" to create the DLL..."

Another user could flash his LG G7 following this tutorial and I already flashed two LG G7, so it should be working.
[LG G7 ThinQ  Guides, News, & Discussion] urimberry:
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?

[LG G7 ThinQ  Guides, News, & Discussion] mattonxda:
Hmmm, I'm not seeing anything at any point that says setdev.bat while installing nor in the lgup folders, so I don't know how to follow that step.

If I use the tool to extract the dll from the kdz then I get a "DLL for G710ULM10f is not installed properly." error. Not really sure where to go from here. I tried redownloading, uninstalling and reinstalling everything from scratch multiple times and it's one of those two errors and I've never seen a 'setdev.bat' thing at any point either. Is there a video somewhere of someone going through this, I've got to be doing something wrong.
[LG G7 ThinQ  Guides, News, & Discussion] kukuteku:
You are using step from main post, for me doesn't work (like you). Download from my Links and follow the steps. Its not necessary to extract DLL from KDZ, when you execute "setdev.bat" as Administrator, the DLL wil be created...
[LG G7 ThinQ  Guides, News, & Discussion] mattonxda:
Ah I figured it out! The link in your post for LGUP was to the other version, but i found the version with the setdev.bat through the link to the post you referenced.

It's updated woo!

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.

Thanks everyone for help. I flashed G710ULM21d_00_NAO_US_OP_0711.kdz

So far Wifi is working great, a lot better than G710ULM10g.

One quick question. Do I have to change some setting for LTE? I haven't tested it yet, but it was very bad on previous firmware.

You have to use LGUP DUAL (modified LGUP) in order to have all the options you are looking for.

Search for it.
[LG G7 ThinQ  Guides, News, & Discussion] zgpirate:
You don't need all those steps. Download version from post #102, run SetDev.bat (forget part about dlls)

Put phone in download mode, run LGUP, load firmware, click on refurbish option and press Start.

I used this firmware:

https://lg-firmwares.com/downloads-file/21732/G710ULM21d_00_NAO_US_OP_0711

Wait until if comes to 100% and that's it.

So far no problems.

This process worked great for me but one snag was I was plugging cable into USB 3 port on computer. This caused LG UP to always show my model as UNKNOWN and I couldn't progress. Thought I had a bad phone until I plugged into a USB 2.0 port then all worked fine.

Hey, I have a similar problem, when I try to flash with lgup, it starts and everything is fine, it reaches 4% and then it tells me "error _checkcrossdl fail. phone= lm-g710ulm" What can I do to fix it and update to Android 9 :confuso: :confuso:

For those who got problems with "No refubrish" or other modes

https://androidfilehost.com/?fid=11410963190603845019

uninstalled lgup and installed from that files .

follow instructions in readme file . don't forget to use setdev.bat .

then i got all the option.

Used refubrish mode , but got stuck , then used Partitiondll mode and viola , it installed, but got stuck with some lines on bootscreen (forgot what it was called ) , restarted with vol down+power button and once it shut off, pushed vol up to get in download mode. After that used refubrish mode and in installed once again . Phone converted to ulm version and works great

---------- Post added at 06:10 PM ---------- Previous post was at 06:09 PM ----------

use partitiondll mode and then if it gets stuck , reconnect it with download mode and flash again , but this time in refubrish mode

Thank you very much, what I did after investigating was to activate the developer options and activate the oem unlock, once that is done, I continued with the usual procedure and managed a successful upgrade to Android 9, but I feel like the 4G signal and battery performs less compared to the Android 8 version.

I have one of these phones, I got from eBay. I was able to root it and install the Pie '20e' firmware update manually.

The ATT MVNO works on it, but the reception is really low, and worse than my 6 year old Motorola Moto G.

I live in the Baltimore metro, 20 minute drive from the city's downtown, and I'm getting 1-2 out of 5 bars. In the city's downtown I got 4 out of 5 bars.

Edit: I followed the instruction from the following video, and was able to get GPay to accept the card. Also Gpay needs to be manually hidden in magisk, be sure to select 'display system apps' to find it.

I have low reception on mine too for some reason. I have a v40 and G7 both on Sprint. Sitting side by side my v40 has 4 bars and my G7 has 2. When activating the G7 it took hours for it to activate because of the low signal. When you actually make a call/during a call the signal will go from 2 to 4 bars on the G7 and callers say I sound great. I performed a signal test and the v40 always test approx. 20 points stronger. Been using the G7 for weeks and really have no complaints, even with the weak signal it seems to work fine.

So as for myself all those steps worked for me.

But I have a major problem with the Wifi.

It connects but shortly afterwards it disconnects and when I try to reconnect to my access point, it connects but again, disconnects shortly after that.

When I pull out the Sim, the wifi works but when I insert it, the wifi disconnects.

I can manage to make it work by activating plane mode and deactivate it after 5 minutes but if the wifi disconnects 2 times I can't find my wifi on the searching menu so I have to restart the phone.

It's really annoying so I wonder if you have a solution for that.

Remember, be sure to delete any LG´s Soft before follow this tutorial. Do it step by step, its works. Step No.5 its very very importan!!!!!

Like many others here, I also bought a "factory unlocked" LG G7 on eBay that turned out to be a G710PM flashed with G710ULM firmware. I flashed it with the Verizon firmware, and it seems to work great so far. Google Pay isn't giving me an error (although, I haven't tried an NFC transaction yet), SafetyNet checks pass, and system updates work.

One thing I am wondering about is I'm not able to access the "phone info" menu by dialing *#*#4636#*#* with the Verizon firmware like I was able to with the ULM firmware. Is there a way to access that menu with the Verizon firmware?

Also, do you guys think upgrading to Android 10 is going to work without any hitches with the Verizon firmware?
[LG G7 ThinQ  Guides, News, & Discussion] netookska05:
Android 10 won't work you need to crossflash to Korean U+ kdz.

If you try to install lineage with twrp won't decrypt you need to crossflash to another kdz twrp decrypts others with no problem. Then flash other roms (Evo, lineage)

Try these codes for Verizon enter codes press call and enter 000000

The first two codes got me the service code prompt, but 000000 wasn't accepted. The third code worked without a service code.
[LG G7 ThinQ  Guides, News, & Discussion] netookska05:
Ok then just keep putting in 0 until it goes to that menu.
[LG G7 ThinQ  Guides, News, & Discussion] otota:
I think Sprint must have set the MSL code to something other than 000000, so I can't access the first two menus at all. If I enter the wrong code too many times, the phone locks and then reboots.

I saw where some phones write the actual MSL code to the logcat file after an incorrect code is entered, but I didn't find it in logcat files from my phone. I was going to try QPST and QFIL next to see if it is possible to read the MSL code from NV memory. Do you know if that is possible?

It's probably not a big deal if I can't access those menus. I mostly just thought it would be nice to have access to the PRL settings.
[LG G7 ThinQ  Guides, News, & Discussion] netookska05:
To use qpst enable port in hidden menu otherwise phone won't be recognized. You can read nvdata then as well as prl list

On LG website there is a newer firmware version (G710ULM20f_00_NAO_US_OP_0218.kdz) with with build date 02.04.2020, can i follow the same steps and use this instead? Has anyone already tested this?

=====UPDATE=====

So i tried to flash with the latest firmware and all went very smooth, i am now on 710ULM20f, the only issue is very poor data reception (-116dBm 24 asu) barely 1-2 bars and of course data speed is ridiculously slow on T-Mobile..

Does someone have any suggestions on how to improve it?

Should i return the phone to the eBay seller/scammer?

=====UPDATE=====

I did one last try with the Verizon G710VM20g (double flash, first DL Partition and got stuck on Verizon logo for about 5 min.. forced reboot and second flash with Refurbished option in LGUP) and with great pleasure the phone data speed and signal is back to normal and it even received an OTA update!! Firmware is bloated with VZ stuff but it is decent trade off compared with what i spent..

I want to thank you 3 guys for the information. I have a PM flashed to ULM from eBay, bought a few months ago. I was having a problem with low signal, so low in fact it took hours for my phone to activate on the Sprint network and SprintDM was constantly trying to update but never could. I tried the Verizon firmware but could not get LTE to work even with the correct APN settings. Last night I flashed to ULM20e linked above and instead of using REFURBISH I used the Partition DL and all of my problems have been solved. For the first time my signal is the same as my LG V40 on the same Sprint network and my phone activated immediately and SprintDM is finally updated and gone thank god.

I bought a sprint unlocked LG G7(LG710PM) which was converted to LM-G710ULM running Android Oreo from eBay for USD140. It is a brand new device. My main reason for buying this is to use it as a music player. Huawei P20 Pro is my primary device. I followed the OP post/directions with few tweaks and I was able to flash it with latest available Android 9 firmware with security update of Feb 2020. Currently using a data only SIM for streaming music. I have also stored a reasonable amount of FLAC files for offline listen. This is one heck of a media/music device for USD 140.

Update:

I am from Canada, currently using a Fido SIM with this device.

The device came with Android 8(G710ULM10g_00_NAO_US_OP_0913.kdz) and flashed to Android Pie (G710ULM20f_00_NAO_US_OP_0218.kdz).

I happen to search the firmware site and came across Android 10 for Canadian models (G710AWM30b_00_OPEN_CA_OP_0605.kdz).

Can I flash it in my device which is a sprint(LG710PM) converted to USA Unlocked(LM-G710ULM).

Has anyone done it? Any inputs appreciated?
[LG G7 ThinQ  Guides, News, & Discussion] prmbasheer:
I having gone through this thread and some others and came across many instances where dual flash is mentioned.

What they mean by that is : First flash using DL Partition and second flash with Refurbished option in LGUP.

Eg Quote : Smooth re-flash on LGUP Dualmode with "partition dll" select all and second re-flash with "refurbished" option.

I flashed a firmware but only did a refurbish as mentioned in most places. How is this double flash different or better? And what does it do? Or is it required in some cases?

My device was a G710PM converted to ULM and had Android Oreo when I bought. I flashed USA Unlocked Android 9 (GM-G710ULM) using refurbish option in LGUP.

Now, I am planning to flash it with Canada Unlocked Android 10(I am using fido SIM).

Should I just stick to refurbish flash or a partition dll flash required?

If required, how do I do it? Just select partition dll and start? and redo flash with refurbish selected?

Any help/inputs appreciated.
