Greetings,
I bought an unlocked G7 ThinQ from eBay in 2019, Hong Kong seller and it arrived with Android 8.0 which did not upgrade OTA. Interestingly the IMEI indicates the model is G710PM (Sprint US), however the box indicates the model is G710ULM (see pic). The About Phone indicates model is G710ULM!
Over time I flashed to stock Android 9 ULM and Android 10 EM ROMs using LGUP 1.15 command line. Around Oct last year, the phone seems to have lost network: USSD or call functions don't work. I have flashed it thrice from Android 8-10 stock ROMs the problem persists. Despite having updated Google for each ROM (LG CA mentioned some versions of Google was interfering with call logic, read here).
Questions:
1. What stock ROM should I install to fix this?
2. Are there any other commands I need to run using LGUP 1.15 to fix the phone before flashing the right ROM?
3. Is there anything I need to ascertain or reset before to see if some setting is off?
4. Will flashing with the right ROM show the serial no?
The ROM the phone is running atm is G710AWM30e_00_OPEN_CA_OP_0902.kdz
Well am not that well versed with the technical lingo. Thanks.

Hi guys,
I've recently had my Hong Kong H815T repaired and it's come back to me with v10B-OPT1-YT. The hardware info shows H815T.
I had updated via LG Bridge to v20C, after completion the software shows v20C-OPT1-YT, I was hoping it would show v20C-HKG-TT. The hardware info still shows H815T.
Getting further annoyed at this, I decided to use LG UP and 'refurbish' my phone back to V10B-HKG-TT.KDZ for the H815T using the methods provided on XDA. However in doing so, it has flashed back to LP v10B-OPT1-YT BUT now the hardware info shows LG-H815 WITHOUT the T! Does this mean I have disabled Band 40 due to the model number change? Have I just monumentally f**ked it up somehow?
To add more to the problem, LG Bridge still indicates my phone is ready for an update for H815T v20C (04.02.2016) but I had already updated to that version...
Anyone able to help? My OCD is going ballistic lol, I wouldn't have paid extra for the T model if I didn't intend on using B40!!
Is there any way I can get H815T back showing as the model number?
Or at the very least, does this affect the extra radio band available on the H815T (B40 2300mhz)
My baseband version is MPSS.BO.2.5.c3-00101-M8992FAAAANAZM-1.31581.1
Software version is v20C-OPT1-YT.
Prior to sending it in for repairs, I was running v10F-HKG-TT and my model info was correctly displaying H815T.
Christ I haven't had my phone for 7 weeks and I already messed it up eugh.
Any help would be greatly appreciated.

Hello,
Long story short, I have obtained my phone back from repair in Hong Kong (I am located in Australia). Originally the model of G4 was a H815 using software version H81520D_00_0115 I believe from memory. This phone died because of it overheating causing to do a boot loop/stuck on LG Logo screen.
I ended up getting the phone back from Hong Kong, they replaced the mainboard as I thought and now the model of the phone thinks it is a H818N Dual Sim card LG G4 – Running software version V10c-DS1-HQ, which it clearly is not a dual sim card G4 because there is no additional sim card slot. Anyway, phone seems to be working well except the rear camera does not focus (I have had this issue in the past and I resolved the issue by installing the correct software version, eg 20A, 20C, 20D etc.) Trying to update the phone using software update does not reveal any updates. Using LG Bridge reveals an available update for it, it thinks the software version was 20F or 20H not sure, however when it goes to download it does not get past 0% tested on two PC’s.
I have installed the images I have found for the H818N now which are:
Hong Kong H818N10b.kdz (this one worked the best as it didn’t come up with that error message when you reboot if it’s an incompatible kdz image)
India H818N10d_00.kdz
India H818N 10F.kdz
With no success in fixing the rear camera issue. I have not factory reset though as I don’t think it would have much of an impact.
Have tried to loading: H81520D.kdz image but the LGUP utility (which I have been using for the above process) says KDZ file is invalid, I assume this is because it detects the phone as H818.
Does anyone have any suggestions or locations where I could download more images to try like H818N 10A,B,C etc? Or if there is something I should do cause I have had nothing but issues with these phones
Kind regards
Hello Members,
I will start with a bit of a back story. I ordered a G4 H815 off ebay and the seller information showed it is coming from Hong Kong. Upon arrival, I checked the phone's hardware using CPU-Z and everything seemed fine. The back plate and the about section of the phone both said the phone is H815 model. The android version of the phone was 5.1 so I tried checking for the phone update through ota but it said there are no updates available. So I started searching on the internet for a H815 image file to update to Nougat but I found that Nougat is not available for the 815 model. So I searched and downloaded MM build for the 815 model (H81520b). I flashed it and then later bricked my phone. Sometimes the display stayed blank, sometimes it worked but the radio of the phone never worked. Now after flashing, the phone's about changed the model number to H818. After extensive research and digging through XDA I found that the phone I got is a F500 version refurb (LG or someone did a big scam here). So I downloaded the F500L20c image and flashed it and it fixed my phone.
Later when I checked with imei tracker websites, I found out that my model is F500S and although the L built worked fine for me, the network was very unstable. In order to fix this I downloaded the nougat built for F500S (F500s30b). It flashed perfectly on my phone but I got many errors on startup, so I decided to flash it again but with the refurbish option on the LGUP. The flash started like normal but got stuck at 38% and gives the error 0x2000. After that my phone only boots up to download mode. I tried many times using the refurbish and upgrade option, with the previous and other different kdz's but no success to any of my tries. Any help here would be appreciated.

It worked! Thanks!!
I have purchased 3 G7's over past couple weeks, from the same seller (starts with "w", has a ton of phones). All of them were listed as G710ULM. Here is what I got:
1. One that was "grade B unlocked" came as model number LM-G710ULM, but with empty S/N. Android 8.0.
2. Second one was "grade A Sprint unlocked" came as model number LG-G710PM, has actual S/N, Android 9.0
3. Third one is same as #2.
I am assuming that #1 phone is also a PM model that wasn't unlocked properly.
With that being said, I wanted to make sure what my options are.
1. Can I properly unlock all 3 phones, so I can run updates on them? I plan to keep just 2 for now and #2 and #3 are in a bit better shape than #1.
2. I see a bunch of "GSM unlocked" ULM models that description mentions will not work for Sprint or Verizon. Is that really the case?
3. What other models are unlockable to be used on Sprint?
Thanks for help on this.
Anyone? I would appreciate some answers.
I got one as well, LG-G710ULM. Can not update via OTA (hence stuck on Android 8.0) since I am in the UK and according to LG UK support the IMEI corresponds to US carrier SP (Sprint they reckon). Kind of a bummer that you can not update your cell. Anyway, am also looking to update it, without jailbreaking it if possible.
Bump up this thread!
Its obvious those devices were just crossflashed with ulm software to gain unlock. That said, your best solution to getting an updated software will be to flash latest ulm firmware using lgup

OK, if you could clarify what G7 models can be flashed with ULM firmware, it would be great.
I am pretty sure I will return the "fake" ULM model and possibly keep the PM model - that's compatible with ULM firmware, correct?
What about ULM "GSM unlocked" models that per description don't work with Sprint?
Are there any other models that can be flashed with ULM too?
Hi all, I currently have a G7+ with the model number LM-G710EAW. From this site, there's a few EAW's that get the android 10 update, that is the HK, KR, and SEA. To this day, my phone is still on Android 8. Since that the only way to check the phone region via IMEI is now gone, I have to assume that my phone's region is IDN (I bought it in one of Indonesia's domestic store). With that, I have a few questions
1. Is it safe to flash a SEA KDZ to a IDN phone? Is there any possibility of bricking it?
2. What about the baseband compatibility? Can I still use the cellular network?
3. Is there another way to check an LG phone's region?
Thanks in advance!
