Return to Stock--various process failures--What worked for me

I wanted to share my experience with working with a T-MO G4 (H81120i) that I had rooted, unlocked the bootloader, and had a custom ROM. My goal was to return it to stock so that I can turn it in(to jump). I tried:
The 2014 LG Flash tool. It failed out multiple times with a "Cannot connect to server" error.
LG Bridge tool which failed multiple times too. The device was not recognized.
LGUP which was reccommended by someone. I have no idea how you would flash or restore wit hthat tool. So, that was a dead end.
So, what worked?
I downloaded the flashable complete zip for the stock t-mo G4(20i) and then left it at that. Its still showing bootloader unlocked on startup so I asm wondering about setting going into fastboot and OEM locking or relocking. The question is...is this last step necessary?

its only if you want to send to LG... so they wont noticed it was bootloader unlocked.... if you relock it will you .. take a video of it...
someone claim it can be relocked... mines locked... so if it can be relocked then i would unlock it..
but it will be nice to see a video that it can be done...

Flashed 20i---no calling, camera on AT&T

I cannot make phone calls or use the camera on my H811, currently flashed to stock H81120i.
I got from eBay a used, carrier-unlocked H811 with a bad ESN that I plan to use on AT&T. It was on 81110h when I got it.
I enabled Developer options, OEM Unlock, and USB debugging.
Code:
adb reboot bootloader
just rebooted the device, no bootloader.
Via LGUP, I flashed to H81120i KDZ, after which I successfully unlocked the bootloader, installed TWRP and then CM 14. I could text and surf (via wifi), but the camera and calling aren't working. I hadn't tested these features before.
Via TWRP, I installed a stock T-Mobile H81120i-Flashable.COMPLETE.zip. This did not solve the problem, so via TWRP I wiped everything but my SD card, and then re-installed that stock T-Mobile H81120i-Flashable.COMPLETE.zip. This did not solve the problem.
Via LGUP, I re-flashed H81120i KDZ. Still neither the dialer nor camera worked. Thoughts/help diagnosing the issue?
Should I flash a newer KDZ? Would this possibly solve it? I've tried to manually add an AT&T APN and set the network, but I cannot tell if that worked. When I request Permanent Unlock, the T-Mobile Device Unlock returns a schizophrenic answer. It says "Unlock Failed", then below that "Unlock Approved : Mobile device is permanently unlocked."
If this were a hardware issue, how would I prove it?

Yeah, that's possible. Two different symptoms of two different problems.
I just did a factory reset on the device itself. I'll see if that does anything.

I was having the same problem and what fixed it for me was running the software update in the phone from 20i to 20o. Just go to the phone settings and check for an update. For some reason this worked perfectly for me and restored all hardware functionality.

Same problem here. I hope somebody have a solution.

Yes, I've tried that method it, it still won't allow me to enter the bootloader. I've tried to enter recovery mode as well but i can't either.

is your phone a h811 and not a frrankenphone .. means it says h811 but actual model maybe another . thats reason maybe you cant unlock.

It's definitely a h811, it says it on the back of the phone, underneath the cover.
But I did buy it unlocked so I could use my sim card.
Maybe that is the reason, but I really don't know.?

thers 2 types of unlocked.. sim carrier . means you other sim not tmobile and... bootloader unlocked to flash custtom roms and kernels ect...
just in case you have doubts.
you want to make sure is a h811.. open up phone and take motherboard and read model number on motherboard plaque.

only thing that comes to my mind is that your phone is not a h811......
plastic and software says it is. but maybe your motherboard could be h810...
if you cant find a fix for this.. open it up search for dissasembled video of LG G4 and take motherboard out physically.
and read the plaque variant model... maybe its not h811 thats why it might say its locked..
or return it.

[GUIDE] LGUP for all (no root needed)

Greetings everyone, i go by the name Ainz Ooal Gown. Here i bring you the Official Guide on LGUP to fix a Brick of your device or to simply Cross flash/Upgrade your device from Windows.
First things first if you try this and end up with a brick or your device transforms and tries to take over the world; it's not my fault you messed up not me. So just read all of this thread not just the O.P to, and get out of a bind if you reply with "the thread is too long i wont read it please help" don't expect anything short of "there's a search bar use it"
Second things have changed cross flashing no longer unlocks your Sim capabilities, you must contact your Carrier to have your Sim unlocked. The only other thing you can do is buy the US Unlocked model and root that one.
Third and i can't believe i must add this those of you who have a T-Mobile V40 if you flash a T-Mobile KDZ you'll be fine....if you flash any other KDZ enjoy and expensive Paper weight.
Download These FIles: DLL LGUP UI_Config
No root:
Step 1. Install the provided LGUP.msi (you should now have C:\Program Files (x86)\LG Electronics\LGUP)
Step 2. Install the provided DLL (you should now have C:\Program Files (x86)\LG Electronics\LGUP\model\Common)
Step 3. Extract the LGUP_UI_Config_m250n_[cxz].zip file anywhere on your computer, then copy or move the file to the common folder (the same one the DLL installs too)
Step 4. Enter download mode and flash any KDZ that is compatible with your device with the Refurbish or Upgrade options.
With root:
If you're rooted and BL unlocked, ALWAYS use Partition DL unless you want to go completely unrooted/bootloader relocked.
Download the previous files and LGUPCompatableLAF
Make sure your using fastboot with USB 2.0, it may work with 3.0 but it's better to use 2.0
Step 1. Extract the LGUPCompatibleLAF.rar file anywhere on your computer.
Step 2. Put your phone in fastboot mode. If on Oreo, just power off and hold vol down while plugged in, if on PIE Power off press vol up, while plugged in.
Step 3. In Windows 10 right click the start button and choose either "Command Prompt" or "Command Prompt(Admin)"
Step 4. In the command prompt type cd followed by where you extracted the rar for me it's "cd C:\Users\juanj\Downloads\Flash\LGUPCompatableLAF" ( Windows 7 and older simply when in the extracted folder Hold Shift on your keyboard and right click and choose "open a command prompt here" ).
Step 5. We need to get into the V35 Engineering bootloader, run this command: fastboot.exe set_active b and press enter. (If your on Oreo and have V35 bootloader in Slot_a skip this step.)
Step 6. Reboot, and it should boot straight into the v35 eng if you were already on PIE.
Step 7. Run this command to flash the LGUP Compatible LAF: fastboot.exe flash laf_a laf.img press enter.
Step 8. Now, we need to get back to our A slot, run: fastboot.exe set_active a (again Skip if your already on Oreo with V35Bootloader in Slot_a).
Step 9. Reboot by pressing and holding vol down and power while your device is plugged in (let go of the power button and volume down button and now press and hold vol up before the LG Logo shows up). You should be in download mode and LGUP will work.
Step 10. follow the non root part but use Partition DL, Select all and uncheck abl_a and laf_a to keep the bootloader unlocked in Slot_a then abl_b and laf_b to keep V35 Fastboot access in Slot_b.
Thanks to: @CXZa @maxmotos @Xsavi

Thanks for posting this. Can we use this to flash any v405 rom (except tmobile) to any lg v405 v40 phone without 9008 mode?
Can we not flash twrp to recovery for the lg v40 as opposed to using the laf partition? I got a copy of twrp.img from vlad for the v40 which looks like was created by Precious Princewill. I haven't tried it yet. Frankly want to make sure there is a working lg up in case i lose recovery. Also not sure how twrp works with PIE. Does it allow you to flash to both slot a or slot b?

Posts like this sometimes makes me wish I didn't get bl unlocked and root.. So much simpler. With lack of anything really interesting to test and play with like crossflashing on the V30 for example, I can't find the motivation to actually do any of this..

yes you can have the older TWRP 3.3.0-0 in one slot and the newer TWRP 3.3.1-0 in the other but you can check your active slot in the reboot section of TWRP

You know what, I never actually checked whether mine came with TWRP or not (again lack of stuff to flash). Prolly worth a look see.
GSI huh. Would be great if it'd work properly. My local carrier uses bands that US phones don't enable / use which is why all my LG phones run Korean fw. Those are the only ones that play nice, otherwise it's wifi-only-land fer me.
This is one peculiar thing I've noticed with LG phones so far. Even if the phone hw itself supports every single band under the sun (like me old V30), running certain regional fw disables some of them. Specific to the V30 : Logic dictates that you can go into service mode and enable those and alls good yeah? But no, not with LG. You do that, it then locks you onto those bands never auto-switching anymore. Which sucks when you swap sims or roam on other networks. Like.. dude.. WTH??

This has been true of almost every manufacturer now. There are no truly unlocked world phones, at least not in the US. Each firmware is locked to the bands for that carrier with little to no ability to cross flash the radios or enable bands. I have at&t in the USA and they have some sort of deal with most carriers that don't allow their firmware to be posted and their phones are all bootloader locked. You can cross flash them and get the bootloader unlocked, but you will always lose a few bands.
The LG v40 US unlocked firmware appears to have more bands than most (v405qa) which is what i cross flashed to my lg v40. It supports:
LTE Bands: 1/2/3/4/5/7/8/12/13/14/17/20/25/26/28/29/30/38/39/40/41/46/66/71;
WCDMA Bands 1/2/4/5/8;
GSM 850/900/1800/1900 MHz; 800 MHz
CDMA; 1.9 GHz CDMA PCS; Secondary 800 MHz CDMA
https://www.lg.com/us/cell-phones/lg-V405QA7-unlocked-v40
Although after cross flashing this rom, my phone firmware still show v405ua model#. So I'm not sure that it fully has worked or if the v405qa is just a varation of the v405ua rom.
