I wouldn't say that changing the modem or the modem in general can't be the cause of that error.

but you can do this first > restore your original backup modem partition to the original and crrosflashed variant if those two modems do not fix the error in netflix then we will eliminate that it is the modem partition.

Netflix for me working

You can change to FTM another NT code and see if that fixes it if that doesn't work either then start over step by step to catch where the error starts.

You can consult other users who use croosflashed rom here and ask if netflix works for them.

Edit: did you root your device ?
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:
that you need unlocked bootloader, root and RW.

you can DM me and I can suggest something and perform some tests, yours will only be to send me the original modem images from the JP variant.

does it have a JP variant as a .KDZ rom?
[LG V60 ThinQ Guides, News, & Discussion] WANTEDJAAT:
Hi Thanks for replying.... Finally the good news is Netflix & Disney+ Started working again.

I tried many NT codes with my FTM,,, still was no luck,,, then I started trying other Modems extracted from KDZ..... etc.

Finally I found the solution.. and it was my : BACKED UP ORIGINAL MODEM JUST BEFORE CROSSFLASH. I just flashed it

it worked like charm.. All Back to track..🙂🙂 even LTE and VoLTE is working with that.

(May be everybody should flash backed up modem after Crossflash, atleast give it a try, May be No need to modify the New modem..🙄??)..!!

Actually the Problem was the modem only, May be bcz it was from different Firmware!!. However it was giving LTE support, which the crossflashed ROM was not supporting. But the Original modem of the Device does everything..!!

When I researched I found that These TWO OTTs (may be more) does not support Modified or different variant modems /DNS & VPNs etc.

Thanks again.

May be this post could help any other in future

--------------

Update : After testing it about 1 day My original modem stopped working for LTE. Now I Have to flash the provided New Modified modem. Then LTE is again working.

after you flashed the original modem, does the fingerprint work for you now?
[LG V60 ThinQ Guides, News, & Discussion] WANTEDJAAT:
My device : Lg V60 - V600TM(Uscellular)

[MCFG Status Shows: Row_Uscc]

I crossflashed it to EA OPEN Taiwan(TW) ROM.

[Please note that I switched from Stock USCellular Android 11 to EA OPEN Android 11 as I dont like A12 much, its battery heavy too.]

Currently using Airtel Network in India (All Networks working Fine, with VoLTE Vowifi etc.)

And Fingerprints are also working smoothly.

Hi friends.

I crossflash my AT&T V60 to European Android 12 firmware for POC.

After the firmware, the fingerprint sensor didn't work, and after fixing the serial number and NT code, the modem stopped working.

Thanks for your patch on the modem. I put version3 on and everything works.

Still need to patch the fingerprint sensor.

Does anyone know how?
[LG V60 ThinQ Guides, News, & Discussion] adventurer1971:
The POC region is Poland

[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:
Could you try modem v1 and see will it works for you?

explain mi again, are you croosflashed and fingerprint stopped to work?

Fingerprint fix

1. Open the dialer and dial: *#546368#*600# | Verizon (V600VM): ##228378 (+ send)

2. SVC Menu > Handprint > HandID Logging = ON | ON VERIZON SKIP THIS STEP

3. Device Test > SAAT > Service Menu – Manual test > Optical Fingerprint test

Complete the test and when a green circle shows tap it, when you see a button “pass” click it. At the end it should fail so just click the “fail” button when there is no “pass” button anymore.

Start the test by clicking "start", then hold the green circle with your finger till the test finishes. On the last test it will fail so just click on "fail".

Repeat 3 times and try adding a fingerprint, if fingerprint still does not work just restart and retry again.
[LG V60 ThinQ Guides, News, & Discussion] adventurer1971:
1) What is the point of trying the modem version 1? I read your description and decided to flash the universal version at once. It seems to me that the Version 3 for all occasions. But if very necessary, I can try. I flashed it through QFIL, it flashed easily and in one go. Respect for your work!

2) I reflashed the phone 5 times during last couple of days - tried different variants, some works, some does not. Tried Android 11. But the fingerprint scanner did not work even once!

3) I also tried the method you described - it does not work.
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:
1) The purpose of flashing the v1 modem is so I can figure out what your fingerprint problem is, in the description I said it's better to use a lower version because it comes with less changes.

2) Did you unlocked bootloader ?

3) Could you take the original ATT A12 stock modem and flash it then let me know if your fingerprint works?
[LG V60 ThinQ Guides, News, & Discussion] adventurer1971:
Straight to number 3) if I had an ATT A12 I wouldn't do anything! I had A10. I live in Ukraine and update the firmware to A12 officially there is no way!

Number 2) I have not unlocked.

Number 1) I am not a system technician, but a simple engineer. I have no idea in my head that the fingerprint scanner can depend on the modem.
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:

This post is a continuation of my conversation on the v60 discord servers.

I'm running a ProjectElixir a13 gsi rom which can be found here. The rom is running great with the exception of no 5g connection even though it is available and I have used it (tmob a12) in my area. Lte is working but download speed are absolute **** which is my original problem.

I've loaded the Universal modem found in post 1 into my running ProjectElixir rom via Qfil and to my supprise it booted and Lte data is working. The problem is, I still have very ****ty download speeds.

I'm getting no NT code errors but wondering if this could be something a simple as an FTM modification?

If anybody is going to try the rom I listed above, remember that this a system img file and can only be loaded to "slot a" via fastbootdd. Trying to load it to "slot b" caused Kernal Panic and will not boot. YOU WILL LOSE ALL DATA by installing this rom!
[LG V60 ThinQ Guides, News, & Discussion] M.Z.F:
Will it remove network lock ?
[LG V60 ThinQ Guides, News, & Discussion] hooutoo:
I haven't a clue. All my phones are NT/BL unlocked.
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:
did you try a patched modem but on a stock modem and then check the speed, it's probably a case of your region because the others don't have problems with the modem. You can change the speed and bands ucarrier_policy.xml may also cause incomplete information in the OP partition where the settings for carriers are.

I can't make many changes in the modem because everything is essentially encrypted. I couldn't even get it to be one universal and stable modem because there are a lot of files that depend outside of the modem. And I don't have the ability or the will to test because the v60 is now my everyday phone and I can only test things that I'm sure I don't need to delete

So far, no one has complained about the speed of LTE or 5G, what is it in your case, I am not sure what it is, although I believe it is about the frequencies, first we should be able to load the .mbn profiles from the modem through the PDC, but we can't, I hope that that case be fixed in A13.
[LG V60 ThinQ Guides, News, & Discussion] hooutoo:
I've now Qfiled your modem img v3 into ProjectElixer a13 gsi rom and it boots just fine, and lte dl speed perhaps a little better. I'm thinking now that your first statement concerning carrier.policy.xml is a good idea. I have an old copy of my Tmob 5g carrier policy (attached below) but having a helluva time getting qpst efs explorer to work. Seems it won't recoginize my phone.

If you could, maybe send me a copy of your tmob carrier policy xml file. What I really need is acopy of a13 40a carrier policy just to check is there are any new changes.

BTW, I'm rooted, so can copy any file into android. Wondering if carrier_policy.xml can just be copied into Android?
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:

I don't have my carrier_policy.xml, I have EA rom, I can only send you one .xml from another person.

Qpst file explorer is the only way I know of?!?I just swapped a modded carrier policy in to my G8x to enable 5g.I don't have a T-Mobile variant to snatch it from A13 or I would and send it to you.I wonder if the USC variant was updated OTA to A13?I'll check it out,and let you know Hooutoo.Turn developer options off,and then try Hooutoo!I had this issue trying to repair an IMEI on a T-Mobile variant!
[LG V60 ThinQ Guides, News, & Discussion] hooutoo:
Qfiled your V1 modem and it's a deffinite no go! The phone boots but radio doesn't even turn on, so no phone calls and no data. The V3 modem seems to work the best. Haven't tried V2.

Now, on to my problem. Since custom roms don't have *#546368#*600# capability which is really just an app btw, I can't run SVC Menu>Port Check Test>enable. And no you can't install "hidden menus.apk" because of a conflicting UUID. So I ran "setprop sys.usb.config diag,adb" thinking that this was the same as the port check test, then manually loaded the Qualcomm HS_USB Diagnostics 9025 but the device won't start in windows. It returns a "This device cannot start. (Code 10) error". What all this mean is, I can't run EFS Explorer. ANY SUGGESTIONs here?

My second thought was to just Qfil the EFS partition but in fact it's not a partition but rather a directory within a partition. Does anyone know which partition? When I know that I'm gonna load the partition and see if it boots.

This is all very tedious but if I can figure it out, I'll hopefully then be able to apply it to any a13 or a14 gsi rom.
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:
so I was thinking in which partition it could be, but that's just a guess, it's certainly in lun5, then if the partition is independent for certain components of the device, just restore to a new device. But it all has to be tested. I guess where the carrier_poicy is, there is also the nt code, but if it is related to the Imei, then restoring the partition will not work.
[LG V60 ThinQ Guides, News, & Discussion] hooutoo:

[LG V60 ThinQ Guides, News, & Discussion] hooutoo:
Well that's a freaking pitty. I stiil haven't found a way to put the custom rom into diag mode yet so I can't use EFS Explorer tool. But the good news is it may not be necessary. As I already mentioned, when I first flashed your modem.img v3 I got modestly better dl speeds. Now its somehow changed. Maybe tmob was screwing around with their equipment in the area or something else was influencing the network speed, but suddenly I got this.

This is with LTE only, no 5g connection was ever made. This is by far the fastest DL SPEED I've ever seen on this phone. The qcom x55 modem on this phone can absolutely run.
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:
glad you are able to solve your problem that's good speed also you can try with V2 i think it will work for you too.
[LG V60 ThinQ Guides, News, & Discussion] hooutoo:
At this point, unless you just need to know whether it'll work or not, I'm completely satisfied. I've never even seen 5g get to that speed, at least not in my area.

BTW, in a nutshell, what mods are you making to the modem img. Specifically, what changes to V3?
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:
You can unpack each modem separately and you can see what changes have been made. There are some files from A10 because a10 is much more flexible and less restrictive compared to newer firmware.
