LG G4 H812 (Canadian) Intermittently No Service - G4 General

I found a used LG G4 that was locked to Koodo for a friend of mine. I researched to make sure that it supports the AWS 1700/2100 band since my friend is on Eastlink (similar to Freedom Mobile). At first everything worked fine, but now he is getting intermittent disconnections from the network where it says "no service." I had him choose the option without LTE, and at first he got service again, but then he didn't get mobile data, and the connection randomly dropped anyway (for calls and texts).
I had him open the service menu via *#*#4636#*#* to turn off the radio, but as soon as he goes to "Phone Information," he gets the message "This application does not work on this device." So Koodo blocked the menu. Wonderful.
At this point, I'm really not sure what to do. Has anyone had similar issues? I've rooted and installed custom ROMs on my own phones several times before. Would installing a custom ROM help? Or maybe just flashing another modem file?
If anyone could help, it would be greatly appreciated. I was trying to help my friend save some money. His old phone was 8 years old and was a cheapo that was laggy from the start. I recommended a "higher end" used phone rather than another cheapo. He's running a business and has 9 kids, so... I would really like to get this working for him.
Edit:
Problem is solved. My friend is no longer experiencing intermittent "no service'" or anything. Here is what I did:
1. Followed these instructions to unlock the bootloader.
2. Flash stock Nougat zip (instructions also say "After that and while still in TWRP: Choose Reboot -> RECOVERY ! This should ensure TWRP will not be overwritten on Android boot")
3. Flash Nougat modem zip
4. Flash my model's baseband (again; was already done during bootloader unlock)
I realize now that I might have not needed to unlock bootloader at all, and could have used LG Up (new) to flash a kdz. But oh well, it's all done, and now my friend has Nougat (the Canadian variant abandoned updates before Nougat).

Assuming he's carrier unlocked, if he's using an old sim card from a previous carrier, he should purchase a new sim card from his current carrier.
If he hasn't already tried this, suggest he do a network reset: Settings > Backup & reset > Network settings reset.
If no go, his alternatives are to (assuming he's not bootloader unlocked): try a factory reset; next, re-flash his appropriate kdz in LGUP-NEW. He should backup his userdata first.
If bootloader unlocked (UsU) he could re-flash his modem.bin or modem.img file from a SALT extract of his appropriate kdz.

I've already done a factory reset of the phone. Is a network reset necessary, or would the factory reset cover that? His bootloader is not unlocked... yet. I will attempt re-flashing his kdz and/or just the modem if the network reset at this point is unnecessary. I'm looking at lg-firmwares.com and don't see Koodo on that list (the phone was originally put out by Koodo), so I assume Telus (Koodo's parent network) would be a safe one to use (MM)?

I found a bigger list here. I found the link in this guide.

Network reset is your first & best option. Re-flashing the kdz is your last option.
Use this site for the kdz download and scroll down to and use this Telus kdz ( H81220z_00_0327.kdz: it does work on Koodo as well): https://lg-firmwares.com/lg-h812-firmwares/firmwares/

Thanks! I am getting him to do a Network settings reset right now. I'll wait and see if that resolves the issue. If it doesn't I will attempt flashing.
I do have a question about the bootloader. You said that it is required to be unlocked. But I read that on the H812 you can't unlock the bootloader. So how does that work? Can I just flash a Marshmallow kdz onto the existing MM OS? I see that his current software version is H81220z. I thought that since there is no root (and no bootloader unlock?) for MM, that I have to downgrade to Lollipop (as explained in these instructions). I thought an unlocked bootloader is always a prerequisite?

Aha! I searched and searched and eventually found this key post. It points to this thread here about (kind of, sort of) unlocking the bootloader and also recommends a backup with SALT.

Yes, quite a number of us now have unlocked our bootloader, thanks to the unwavering steadfastness of @steadfasterX, author of the UsU unlock method.
Ensure you do upgrade to the latest Telus 1220z MM kdz (even though he is on it already), I linked first with LGUP-NEW to see if the network connection is restored and then do a SALT backup as recommended before unlocking. It is very important you read the OP in the USU unlock thread thoroughly, making sure you understand it complete;y, to avoid easily avoidable screw-ups. You should make sure your friend understands the process and risks as well before proceeding.
steadfasterX has also prepared custom roms for our unlocked H812's and I can recommend both the ASOCP N and the Lineageos O roms for your H812, if your friend doesn't rely on any LG stock proprietary apps, otherwise you can flash him a special stock Nougat LG rom (all available in the Downloads section in the UsU thread).

My friend's phone says that it's MM and software version is H81220z, so he should be good there.
I'm interested in Lineage Oreo, and I'm a little confused about the instructions, if you don't mind enlightening me. So first off, I understand that UsU is required first. In the UsU instructions, it says:
Flash the baseband package now: <model>_UsU_baseband_flash-in-twrp.zip
Click to expand...
Click to collapse
But in the Lineage O instructions, it says:
If you have ever flashed the UsU baseband package: Clean flash the modem partition from your backup in TWRP.
Click to expand...
Click to collapse
So I assume that I'm supposed to just skip flashing the baseband in the UsU instructions? What about installing SuperSU afterwards? Is flashing that new baseband required?
I guess what I'm wondering is, should I flash the baseband, like in UsU instructions, then revert back to the original baseband, like in the Lineage O instructions, or should I just skip flashing the baseband in the first place?

The reason you should re-flash the same kdz, is to see if it gets the network connectivity issue solved before proceeding with anything else as you may find the problem still exists.
If you are planning to go the the LG Nougat stock rom, the baseband should be flashed. If you're going to the H812 Lineage O rom, just flash the modem.bin file from the SALT backup you do - you can always flash the baseband later if there is a problem and it is needed. Flash SuperSu after.
You're still forgetting the Thanks button, eh ... ? Hint: It's a good habit to get into when receiving help from other members.

Well, I successfully unlocked the bootloader using UsU. I flashed the the baseband package, because I figure I will first re-flash the same kdz. I also decided I will flash stock Nougat because I figure it will be more stable for my friend. Unfortunately, I only got as far as flashing the baseband package and SuperSU.zip. When I try to boot into the OS, it just hangs on the "LG Life's Good" logo forever. Should I go ahead and flash the MM kdz using LG Up new anyway? I already tried a factory reset, and it didn't make a difference.

If you want to hard brick your friend's phone and possibly lose a friend, sure, ignore the UsU thread OP warnings ... i.e., DO NOT flash with LGUP-NEW now that the phone is unlocked. If you're going to the stock Nougat, flash the N modem from the UsU thread. If that doesn't work, flash the MM modem from a SALT extraction of a clean Telus H81220z kdz.
Suggest you read the OP in the UsU thread fully, i.e., all of it including the FAQ's and make sure you understand it all this time.

I finally figured out why I'm so confused. Original, when you said this:

I misread. I thought you said "assuming he's bootloader unlocked." So I kept thinking that in order to do ANYTHING (flash the kdz), his bootloader had to be unlocked.
I read the OP over and over, and didn't see the part about never kdz flashing with LGUp, coupled with my misunderstanding that I had to be bootloader unlocked in order to flash with lgup. But I finally found what you're talking about in the FAQ.
You can't! At least for the KDZ flashing part: not yet.
SALT will allow flashing of KDZ files with the upcoming version 4.0 but until then do not flash with lgup and do not use the LG Android internal updater --> You WILL 100% brick your device.

I realize all this is a risk to my friend's phone, it's just that I was the one who talked him into buy a used decent phone, rather than buying a new cheapo crappy phone. I just wish I didn't misread what you had said and tried flashing with LGUp *before* I bootloader unlocked.
It's been a long week.
P.S. - I wouldn't lose him as a friend over this. He is very technologically challenged, and keeps thanking me over and over for helping him with all his previous phones, for giving his wife one of our used old phones (she previously had no phone), for helping set up his network with a Tomato firmware router and OpenDNS so he can know what in the world his kids are doing online and have control over the network, etc. So if I bricked his phone, I would just buy another one used for him. He wouldn't care. He just needs a half decent, inexpensive phone to run his small business. Right now, he's just using his old phone for the time being. It's a MotoE that he's had for the last 8 years and he says, "I need to upgrade." Lol

I searched and searched for the Nougat modem (at this point, I might as well upgrade to Nougat), and this is what I found. Is this correct? Or is there another version that I need because that one isn't compatible with my phone? I also assume that the modem zip is flashable via TWRP? I see the "META-INF" folder.
This is the stock Nougat I was going to flash (with TWRP? It looks like a flashable zip). My ARB is 0. My GPT compatibility is H811.
I see in the N stock that there is already a modem.bin file. So should I first flash the stock N zip, and THEN flash the separate N modem? Also, the instructions say:
16) I just wanna flash Nougat STOCK. Are there any worry free UsU downloads for it available?
Sure: here
After flashing ensure you flash your model baseband package!
After that and while still in TWRP: Choose Reboot -> RECOVERY ! This should ensure TWRP will not be overwritten on Android boot

So, in summary:
1. Flash stock Nougat zip
2. Flash Nougat modem zip
3. Flash my model's baseband (again)?
And if none of that works:
flash the MM modem from a SALT extraction of a clean Telus H81220z kdz

It was locked to Koodo, and the original owner told me that. I called Koodo, gave the IMEI, and they gave me the Network unlock code. If it was blacklisted, wouldn't Koodo have said something?

I flashed stock Nougat, then Nougat modem, then the H812 baseband, then rebooted directly back to TWRP. Then I booted up the phone and it was in Spanish. So I changed that to English. Then I had rebooted the phone again (adding a SIM card for testing), and it was in Spanish again, so I changed it back to English. Then I rebooted the phone again, and it was in Russian, so I changed it back to English, and also deleted all the extra keyboards which included Spanish and Russian (at least, it looked like it was Russian). Rebooted the phone a couple more times, and it stays in English.
So far, everything is working.
Thanks again for your help! Will report back if the intermittent issue comes back, or if everything continues to work well, in case anybody with the same issue is looking for a fix.
On another note, out of curiosity, I tried *#*#4636#*#* on the Phone's dial pad to open the service menu, and noticed that Phone Information is still blocked. Just curious... is that a ROM thing? Or a baseband/modem thing?

Not sure about the language issue as I haven't used the stock N rom but if it continues to hold, no problem. Make sure you do a TWRP backup when you have it where you want it.
The 'secret' menu accessed from the dial pad hasn't worked for me in AOSCP N or Lineage O so it may be a rom thing. *#546368#*812# is the dial pad code that should be tried in any event.

I just wanted to report that my friend no longer has any more issues with no service. Everything is working well. I will edit my first post to state that the problem is solved and what I did.

Convert Canadian 6045i to US 6045i with all updates (performance, stagefright, etc).

Be very careful doing this, you could brick your phone if you aren't - you have been warned.​
Okay, so, us Idol 3 users in Canada are stuck waiting for Alcatel to have any updates blessed by our cell carrier (Bell/Virgin, Telus/Koodo) before we're "allowed" to get them. And as we all know, Canadian cell carriers aren't exactly prompt about this sort of thing. So what's an enterprising XDA user to do, then? Why, convert your device to a US model, of course!
Step 1: Install TWRP
That can be done with this thread here, courtesy of @DallasCZ
Step 2: Download the latest US firmware
That can be done by downloading this file here, courtesy of @famewolf
Step 3: Flashing
Okay, so first, BACK UP YOUR EXISTING FIRMWARE. Take a system image, or nandroid, as your choice may be. Be sure to back up the boot partition as well, in case you ever want to go back to stock Canadian firmware! Then, do the following:
Decompress the US firmware
Copy the decompressed 1970-01-22--16-43-23_LRX22G_release-keys folder into your TWRP/Backups/XXXXX/ folder on your External SD card or USB-OTG storage, where XXXXX is your device ID assigned by TWRP when you backed up your existing firmware - it is also the same as your device ID if you type 'adb devices' with your phone hooked up with USB debugging enabled for adb commands.
Wipe everything *but* External SD and USB-OTG in TWRP. (This entire wipe may not be needed, but as @KashRaman pointed out, if you don't at least wipe cache, you could have issues after flashing the new firmware)
DO NOT REBOOT - go back, and select Restore in TWRP. Pick the US firmware backup.
Flash *both* the boot and system image.
Reboot System. If your phone does the same as mine, it will seem to get stuck on the 'Alcatel/Smart Move' animation. Hold power until the phone turns off, then turn it back on. It should quickly go to 'Upgrading Android'.
You're done! Set up your device, and feel free to install SuperSU, remove bloatware (AVG? Ugh), etc.
I didn't even need to add APN info for Virgin Mobile, it already set up the Bell Canada APN - worked right away out of the box.
One comment to note - I do not know that a Canadian device converted to a US one can get OTA updates, as I believe Alcatel uses some sort of IMEI identification to see what OTA ought to be passed to a device, but I'm unable to confirm this. Of course, I'm personally fine with just manually updating when need be, but that's up to you to decide if you are as well.
AS ALWAYS, BE CAREFUL, DO THIS PROCESS AT YOUR OWN RISK
Don't forget to thank @DallasCZ and @famewolf for their posts/uploads making this possible!​
To save you some pain you can more thank likely flash the system image and boot without wiping your /data.....if for some reason you ran into issues you'd still be able to go into factory recovery and do a reset which deletes data.
Also to anyone who actually uses AVG the pro version is free on amazon appstore today only.
Also you don't have to INSTALL twrp...you can opt to only boot into it using the instructions in the system image thread if you prefer to keep stock recovery.
If I had to bet I'd say you'll get the USA notifications but we will find out on next update.

Totally correct on the TWRP thing, though I prefer it to stock recovery, and updates work just fine with TWRP as well.
As for the not wiping - again, correct, I just come from the 'do a total wipe' school of flashing things, to avoid any possible weirdness

When restoring the UE40 firmware the first time you go into system update checker you need to delete the existing UE40 update as it kept it around...you should then be able to check updates as normal.
Manually update
At the end of your post, you say that you update manually.. where do you get your update ?

I mean that when the next update comes out, if I can't use the OTA update, I'll wait for someone to upload it here, and then I'll manually apply it. If you follow the directions in my post, you'll be totally up-to-date as of August 15th, 2015 - I'm referring to the next update, whenever that may be.
Thanks for the guide!
Was able to update my Canadian idol 3 without installing twrp
Just fastbooted into it and did a backup of my old CDN setup and restored with the file above the whole update process took about 15min
If **** hits the fan I can still restore back to the original CDN ROM with twrp and my backup.
Dt2w works every time now and chrome scrolling is vastly improved definately worth updating. I may flash back to Canadian system image when they finally release it
To anyone on stock Canadian firmware please post once an OTA is available (and what carrier you are on)
anyone else have lost LTE and get bad network speeds after converting? I had 60mbps with canadian firmware and now i get around 5mbps and lots of network drops.

I'm not in canada but I would think if more folks were experiencing issues like that they would have mentioned them here already. Did you do a factory reset and start clean or did you keep your previous data around after changing firmware? In this case I'd really recommend starting clean with the exception of using tools like Titanium Backup to backup all your user apps+ their data (or you can use Helium if you don't have root).

I'm not in canada but I would think if more folks were experiencing issues like that they would have mentioned them here already. Did you do a factory reset and start clean or did you keep your previous data around after changing firmware?

I had cleared the cache and did a factory reset only after i confirmed the flash of the US firmware was ok. (i have a really bad SD card which keeps unmounting and didnt want to risk being stuck with a non-functional device). In addition to the network problems i also still had the performance issues everyone mentionned was fixed in latest update. I just did a complete wipe and flashed the US again, now the performance is much much better but i still get only H+ with about 7mbps instead of LTE. But the good thing is the drops seems to have stopped.

you probably tried this but... check that the APN didn't get changed/reset from when lte was working.
That was actually the problem, i did not realize it was a different APN for LTE so it looked normal when I first checked. Thank you very much
Has anyone gotten the Canadian stagefright update pushed to their phone yet?
doesn't work for me!

Be very careful doing this, you could brick your phone if you aren't - you have been warned.​
Okay, so, us Idol 3 users in Canada are stuck waiting for Alcatel to have any updates blessed by our cell carrier (Bell/Virgin, Telus/Koodo) before we're "allowed" to get them. And as we all know, Canadian cell carriers aren't exactly prompt about this sort of thing. So what's an enterprising XDA user to do, then? Why, convert your device to a US model, of course!
Step 1: Install TWRP
That can be done with this thread here, courtesy of @DallasCZ
Step 2: Download the latest US firmware
That can be done by downloading this file here, courtesy of @famewolf
Step 3: Flashing
Okay, so first, BACK UP YOUR EXISTING FIRMWARE. Take a system image, or nandroid, as your choice may be. Be sure to back up the boot partition as well, in case you ever want to go back to stock Canadian firmware! Then, do the following:
Decompress the US firmware
Copy the decompressed 1970-01-22--16-43-23_LRX22G_release-keys folder into your TWRP/Backups/XXXXX/ folder on your External SD card or USB-OTG storage, where XXXXX is your device ID assigned by TWRP when you backed up your existing firmware - it is also the same as your device ID if you type 'adb devices' with your phone hooked up with USB debugging enabled for adb commands.
Wipe everything *but* External SD and USB-OTG in TWRP. (This entire wipe may not be needed, but as @KashRaman pointed out, if you don't at least wipe cache, you could have issues after flashing the new firmware)
DO NOT REBOOT - go back, and select Restore in TWRP. Pick the US firmware backup.
Flash *both* the boot and system image.
Reboot System. If your phone does the same as mine, it will seem to get stuck on the 'Alcatel/Smart Move' animation. Hold power until the phone turns off, then turn it back on. It should quickly go to 'Upgrading Android'.
You're done! Set up your device, and feel free to install SuperSU, remove bloatware (AVG? Ugh), etc.
I didn't even need to add APN info for Virgin Mobile, it already set up the Bell Canada APN - worked right away out of the box.
One comment to note - I do not know that a Canadian device converted to a US one can get OTA updates, as I believe Alcatel uses some sort of IMEI identification to see what OTA ought to be passed to a device, but I'm unable to confirm this. Of course, I'm personally fine with just manually updating when need be, but that's up to you to decide if you are as well.
AS ALWAYS, BE CAREFUL, DO THIS PROCESS AT YOUR OWN RISK
Don't forget to thank @DallasCZ and @famewolf for their posts/uploads making this possible!​

i downloaded the zip restore file for my phone (Model: 6045Y(Europe) Firmware: 5.0.2-010 06) from this thread http://forum.xda-developers.com/idol...dates-t3163745
I also have the twrp-2.8.7.0-idol3 installed on my phone.
I also followed this thread
to find the way to install that ROM, without success. i also installed the root from the zip file in the twrp, but again without success!! but when i open from the twrp the directory TWRP/Backups/XXXXX/ and i copy the .win and the .win.md5 files the phone doesn't see the when i click restore

This guide is for converting a Canadian 6045i to a US 6045i - both are identical models with simply slightly different software. It won't work with a European 'Y' model like you said you have.

Step 1) Make a backup on the device so it creates the directory path you need.
Step 2) Take the time datestamp folder from the backup you have and put it in the folder that has the other time datestamp folders. It's not a complicated process. Installing the "root" from the zip file does you no good because the time datestamp folders need to be under a folder with your device id (ie what shows up when you do adb devices).
While the restore process IS the same your questions should be asked in the system image thread if you don't have a 6045i.
According to @petrov.0 it's better for you to install the official 10 06 update (or his modified one in the system image thread) as it updates files in SEVERAL partitions other than system and boot. Again discussion needs to be there.
Apologies to @purple.epod. This will hopefully redirect folks back to the system image thread. I have a line that states to follow your restore tutorial but use their own backup but did not intend for them to be asking questions HERE.

I was originally on the h910 att firmware, then used dirty santa to open the bootloader and root. I found a rom that i really like and ran fast as heck, but it wouldn't sync with my watch. I tried a factory reset with led me to a twrp boot loop and nothing i did would get me out of it. so i tried to reflash twrp and it led me to a bricked phone that wouldn't power on past the boot loader unlocked notification. After tons of research and a little tweaking to a few things i got lgup to recognize my phone and flash the h910pr kdz to my phone. if anyone needs i can make a zip of the tools i used and post it somewhere.
edit- uploading to mega right now. will post a link in a little bit to a zip with my lgup folder configured exactly as it needed. install lgup2016 and the lg drivers then copy the lgup from this zip over the lgup folder in your programfiles(x86). essentially all you really need here is the lgup_common.dll which is actually just the h918.dll with the name changed. i had read the fccid's on the h910,h910pr and the h918 were the same, which meant by a measurable standard they are the same hardware. so i took the assumption the dlls would be compatable. by pure blind luck with the folder layout as shown in the zip and the kdz included as well it took. i was a little worried because i had read someone tried this and could not get carrier service. i thought id at least make the phone usable in case a fix was found.my phone reports itself as an h910pr now but is connected to the att network with no issues, text, talk and web all work fine as well as att services.
I had checked a while back and saw that the h910 and h918 had the same FCC ID, which, as you stated, means they have to be the same hardware. I am using my h910 on T-Mobile, so now that I know (if it fails for some reason) that I can flash the h910pr KDZ, I am going to try the h918.
Sorry that you almost had a brick, but thanks so much for verifying that this works.

Cant get OTAs to install on Perry

Problem is in the title. Here are the Cliff's Notes:
1) got Moto E4 from Textnow
2) fastboot boot TWRP.img (cant recall which image I used but pretty sure it was proper. if this makes a difference I can dig out the TWRP I used and attach it, but I really cannot recall which one it was. Pretty sure I got it from xda though, not the official TWRP page)
3) took TWRP backup of bone-stock device.
4) unlock bootloader at Motorola.com
5) check out the custom roms and found out about the LTE problem. Seanstars fix didnt work for me on several roms, but in his defense I may have done something wrong. I didnt want to mess with it anymore and decided to go back to stock.
6) I found out that I lost my bone-stock-TWRP backup through my own idiocy. I honestly have no idea how I got back to stock but I managed it. Seems to be awful hard to get a stock rom to work with. I must not be looking hard enough but it seems like all the links for Perry stock roms here are dead.
Now to the problem.... after all that I cant get OTA updates. I get notifications, the update downloads,, but no joy.
Device does *not* restart after the update downloads.
Manual restart begins the update process, but then I get the Android on the Operating Table screen. I relocked the bootloader thinking that might be the issue, but now I fear that there is some sort of signature verification issue that is stopping the update.
Trying to give relevant info from the bootloader:
Baseband: M8920_15000.280.06.58.02R PERRY_NA_CA_CUST
Product/Variant: perry XT1766 16GB P3B
I really dont know where to go from here though. Any help is appreciated, thanks in advance.

A number of partitions need to be pure stock for OTAs to work on Moto devices - including many that are not normally mounted. Likely one or more was altered by previous tinkering. Obviously system (never mounted r/w) and recovery; data must not have had dm-verity disabled. Etc, etc.

LG V20 bricked/bootlooping/bootloader re-locked. How to fix?

Hi all -
I have two US996 phones.
Luckily, my primary phone is fine (rooted stock Oreo ROM)
The "backup" phone was previously bootloader-unlocked and also had TWRP and a stock-rooted Oreo ROM on it - but not yet set up; it booted to the welcome/setup routine.
Well, I did a "full" Nandroid backup of my primary phone (TWRP 3.3.1.0) using the beta feature supposedly allowing backup of data as well as the internal storage and wanted to see if it really did fully restore the phone without need for re-entering all of the passwords and other info for all of the apps. So, I tried to restore it to my backup phone.
Well...I screwed up and apparently didn't do an adequate wipe before flashing. Now, the backup phone is bootlooping with a message saying something like "your phone failed a security test and will not boot". I am not able to get into recovery at all.
I am able to get into fastboot mode, and on "fastboot getvar all", I see that the bootloader has been re-locked!! So, of course, trying to unlock it via fastboot doesn't work, since I am not able to get into developer mode to re-enable OEM unlock...any way to re-unlock it and get into TWRP?
Looked at Medusa Flasher, which is supposedly free (1.1.0.1) but when I try to use it I get "card not found" and it won't open, and the file needed to fix this isn't available. It also appears that it's only good for Sony and HTC phones anyway, and some serious hardware dissection is necessary.
Any help would be appreciated!
Thanks in advance.

Flashed the Stock Oreo KDZ. Thanks! phone boots now....but I can't unlock the bootloader in the usual way (using the unlock.bin file from LG) because somehow the IMEI number got nulled - all zeroes.
Edit:
Got the IMEI fixed with this method: https://forum.xda-developers.com/v20/help/us996-imei-null-0s-how-fix-t3876980 - and now the bootloader magically became unlocked.
Now to flash TWRP and a rooted image and all should be well.

Hmmmm....couldn't find the file anywhere on my phone or the computer. I unlocked the bootloader on that phone when I first got it four years ago.

unlock boot loader US996

Is this do-able with out unlock.bin??
I've tried using adb/fastboot. ADB reports the device OK; fastboot can't see the device.
I've tried all manner of drivers to load........ I know there are separate drivers for adb and fastboot.
This is driving me nuts.
Finally, are there different SUB-variants of the 996?? One generic and one US Sprint??

The only issue with that response: The DirtySanta thread you link to lists the following devices, admonishing that any others will get bricked:
- Verizon (VS995)
- Sprint (LS997)
- ATT (H910)
- Korean(F800L)
- USS996 (BPT, UCL)
- Canadian (H915)
Unless there's a typo in it, the USS996 is NOT the same as the US996. The US996 is a carrier unlocked US variant. The other US996 is locked to US Cellular. A bit of clarity is necessary here...

Thank you! I am looking that over. One question I do have for you: Is that dump backup needed for anything beyond the EFS to get the IMEI? Asking only because I was able to extract the IMEI already. I'm not physically working on this till the weekend, so I'm going to read up/download stuff in the interim and go from there. If I end up with questions (and I just might from the bit I've read so far*), I'll append this post or reply to it.
* This is an example of where the uncertainty sets in: "For official US996 model owners that do not want to void their warranty, follow the Dirtysanta Sprint(LS997) method but make sure to flash a US996 Stock rom instead." I'm assuming "official" applies to an actual V20 model US996, regardless of carrier/unlock status. I'm extrapolating that the H915 is an US996 with a differently configured kernel. Since the LS997 is only mentioned separately, is the 997 a CDMA version of the (GSM) 996?
LTE is inferred, GSM is for distinction, so I'm assuming the 915 and 996 are GSM devices. I also know Sprint is/was a CDMA carrier. CDMA hardware would infer different modules would be loaded by the kernel, than for GSM, and could therefore hang or brick the device. At least that's where the rail line used by my train of thought takes me. Or, does the difference between CDMA and GSM versions not matter?
You are correct about the broken links: Tilde88's US996 100% Stock deODEXEd Rom, which is listed in the linked article, is a bad link. I did some fairly general "looking" for that ROM elsewhere, found a couple of articles when Google-searching, but haven't had a chance to check those out (that will have to wait until tomorrow). If it turns out that there is no alternate link to the ROM, are there any other ways of getting it, short of looping @Tilde88 in?

Sometimes downgrading your firmware to root your phone will corrupt your EFS on the phone and you have to restore it to get cell service working again or to bring back your IMEI number.
There are four files that are your EFS.
With the phone powered off, hold the down vol and plug in usb to computer to restore EFS.

Sometimes downgrading your firmware to root your phone will corrupt your EFS on the phone and you have to restore it to get cell service working again or to bring back your IMEI number.
There are four files that are your EFS.
With the phone powered off, hold the down vol and plug in usb to computer to restore EFS.

Before you flash the KDZ to downgrade your firwmare make a DUMP backup of ALL files first it will have your EFS and that's very very important it has your IMEI number. You don't need to dump system or cache.

Ok, so I finally got to where I'm able to run that dump backup. I've been at it for the better part of 8 man hours, and it keeps crashing. Finally got everything backed up except SYSTEM IMAGE. Whenever I try to back up that segment, the backup crashes. You said I don't need to do this against CACHE, which I get. There's both a SYSTEM and a SYSTEM IMAGE, so now I'm wondering if you meant the latter instead of the former... If not, how do I get past this obstacle?
FWIW, I'm writing to an otherwise empty, brand new 32 GB Class 10 card. Initially I was using a surplus 16 GB card, then realized that I was coming up around 4 GB short, and pegged the failure on that. But the same happens on the larger card. In case it matters, the backup gets to about 60% before failing...

Your phone is rooted great.
DUMP backup with LGUP. Might not be to late. Just hold vol up and plug in usb to phone and computer. Go into LGUP and choose DUMP all files. You don't need to dump system or cache. This will save all the files on your computer. Back the files up like google drive or something.
Take battery out and put back in. Then you want to boot into twrp and do a format.
Then your ready to install an OS on your phone. Why don't you check out my rom I made it's stock Oreo debloated. There are some good guides on there also you can follow. link
If you need any more help just ask. I don't mind.
I just wanted to thank you for the guidance to date. Great news: After many fits, starts, wrong turns, interruptions, and muckups both real and imagined, my V20 now has Oreo Lemondrop installed, and I presume it is also rooted.
With the initial hurdle overcome, it's time for new questions (see photos for the first three):
* The device reports no S/N. Normal?
* The OS reports no kernel version. Normal?
* The device still boots to the red triangle before loading Lemondrop. I was under the impression that would go away now, or am I wrong?
* A lot of games and other crud is being installed by Mobile Services Manager. Is that because I missed something?
The latter may not matter much: I'm going to move the SIM from my regular phone to the V20 to see if it will make/receive calls. If it does, it'll get a SIM of its own, so I can use it as a second line. If it doesn't work (I've seen posts about bands not working, etc), I'll be done with it altogether.
However, should the phone work, what'll make this whole enterprise a complete success, will be to install a more current Android release; I'm expecting 10 or 11, but would be tickled if it's 12 or 13. But first things first...

Yeah no SN and no Kernel is normal. It's also normal to have the boot screen come up, it's because your phone is rooted now.
I have to run Oreo because LTE is not working in crDroid or Lineage os. There are proprietary drivers that are in Oreo to make LTE work and they are not in any other android os. But if all you need is 4G then maybe another os would work for you. In the USA they did away with 4G only LTE now. So I thought I would make the Lemon Drop rom, if I have to use Oreo why not make it fast. Plus most everything works in Lemon Drop. Like second screen and so on. I have used crDroid before it's good I will link the files for you.
Update: I found and removed Mobile Services Manager in the latest version of Auto_Debloat. Thanks for bringing this to my attention.
crDroid 11 just format and flash in twrp reboot.
also flash Magisk-v21.4.zip so you can have root.
you may have to flash twrp also I am not sure, it's been awhile before I install crDroid. You can always flash twrp in fastboot mode if you have to.
Take Care.

Thank you again, and you're welcome for the bit on the Mobile Services Manager. My apologies for the lag in responding too; real life got in the way for a bit there. I'll look into your suggestion as I get a chance and will report back.

Not a problem. Because I only have an H910 I didn't get all the bloatware on other lgv20 phones. But that Mobile Services Manager is a huge bloatware that installs more bloatware. So I thought I would try and find it and remove it in the latest version. You can update Auto_Debloat and it should get rid of that Mobile Services Manager for you. All you have to do is just flash the new version in twrp and reboot.
