My progress: LG V20 H918/7.0+ FRP bypass in 2018?

After putting my FRP-stuck T-Mobile V20 away for a couple months, I was unfortunately surprised to learn that very little public progress has been made on the subject since my last give-up. I dedicated the last day to trying to figure out FRP bypass for my LG V20, and upon re-researching, I have...
1. Managed to downgrade my V20 to H91810j, though this version still has all exploits patched to get through FRP (to my knowledge).
2. Upon further research, I concluded that what I need is to successfully downgrade to H91810d, as it's the only pre-December 2016 update available (pre-December updates have un-patched exploits to be able to get into the phone). Unfortunately, this update was the one released on the phones stock from the factory, which made it next to impossible to find a KDZ file as they were't "pushed" to the general public.
3. Through researching countless other threads, I've come across this link (I can't share as I still haven't posted 10 times, can DM if needed for reference) which appears to be the closest possible file to the needed H91810d, except the download is a .ZIP that contains Boot.img and Modem.img, which I'm not familiar with using, and no .KDZ file.
4. Further research concluded that I could TWRP-push these files to a TWRP unlocked device, but because of the locked FRP, such a thing isn't possible. My last and final method (which I will try tomorrow as it's 8 AM and i've been trying to get this damned phone unlocked for hours and need sleep) will be one recommended on another forum, which is to downgrade, reset the phone, upgrade, reset the phone, and continue on until FRP is no longer on the device.
Researching into other devices proves that it's definitely possible, though the V20 (especially the H918 model at that) seems to have far less information available towards achieving this. After giving a selection of paid services a look as well, the majority didn't have the ability to unlock the V20 either, which makes me question what the V20 is doing differently from other devices. If anybody has any information that could help me or the community in the matter, please let me know!

I am not, I would attempt to root but without being able to enable USB debugging, I'm sort of at a stalemate.

Well for those trying, I have a phone on H91810q, and the above process (hardreset link) does not work. when getting to the step to allow unsigned binaries it will not toggle. I tried a few other approaches that might get USB enabled (e.g. via LDB in SVC mode, but it also failed to toggle).
Does any know if you can downgrade an FRP locked phone without USB enabled? e.g. using the process described in the thread http://forum.xda-developers.com/v20/how-to/step-step-guide-lg-v20-h918-unlocking-t3808258
Asking before I have to go find a windows box and spend an hour or so trying, in vain, if it is not possible.

Have you tried downgrading to h91810p first? H91810q might be patched as not to allow this method. Both h91810p & q are ARB1 so you CAN roll back before proceeding

G930F Stuck on Factory Binary

So I had this S7 my father brought me to fix and appearently it has frp lock.
I followed some instructions and ended up installing this COMBINATION [COMBINATION_FA60_G930FXXU5ASD2]) from a website i cant link because i'm new here (hardreset dot info)
What happened is that i can boot into this factory binary > settings > enable usb debugging, but when i try to flash a new firmware i get only fails from odin. I guess it's because of FRP lock.
I've tried to flash other combinations, but the only thing that works is that particular version that i cant find anywhere else on internet ( COMBINATION_FA60_G930FXXU5ASD2 ).
Can anyone give me a hand? I'll ask to every question you need. Thanks a lot. :fingers-crossed:

Once you flash a firmware that works delete the ****ing Google account off the phone. Can't believe how many people mess about with phone without learning the basics. FRP lock is a mother ****er to solve but there's loads of guides.

It doesn't matter, Verizon devices have locked bootloaders that can't be unlocked, don't waste your time trying, it isn't going to happen. Verizon devices have been this way for years now, I don't forsee that changing at any time in the future.

You can try it but I'm pretty certain that Verizon has it locked down. There is a root method for Verizon S7 and S7 edge but no TWRP or custom ROMs that I know of.

Figured I'd give it the old college try. Got Odin to recognize the phone and went through the root process. All looked well until the very end. "Complete (write) operation failed."

And now, using the latest version of Odin (I somehow downloaded an older one the first time around) it got to recovery.img and just stuck there. An exercise in frustration as you had warned. I need a Verizon phone that can 100 percent be rooted. I'm using a rooted original Pixel now but that sucker is getting worn out.

It might depend on what version/build number of stock firmware is installed on the device. That guide might be for an older version of a specific version. If what you have is newer than what the guide was written for, that might be why it failed.
Does it say anything in the guide thread about it requiring a specific stock firmware or specific bootloader version?

I've gone through a couple different tutorials and they all seem to link to the same files that I need to download. It's been frustrating because looking for proper files for a phone this old leads to a lot of dead links. I'm probably going to give it up soon, but you know how it is. There's always "one more thing" to try. I tell you, I'm going to research like hell before I buy another phone. I need to know for sure that it can be rooted. In this case, I inherited my wife's old phone and a quick search revealed that it ought to be a piece of cake to root. There's always some little detail that trips me up. I appreciate your help with this.

Try a version of Odin from around the same time the S7/S7 edge was released onto the market. Some versions work better with certain devices, as android evolved and as Odin gets updated to newer versions for newer devices, there are slight differences along the way that can effect how it works on older devices.
If the stock firmware that you are trying to flash is older than what was already installed on the device, it will probably fail due to not allowing the device to be degraded to an older version, it's a "security" measure put there to prevent you from installing a less "secure" operating system.

Yeah, that would work. It's been so long since I messed around with this stuff -- I've had the pixel for six or seven years I think -- that I've forgotten everything I once knew.

I'll look that up and try it out. Nothing to lose at this point. All I'm trying to flash at this point is the CF Auto Root Tar.md5, as per the instructions.

No, I mean does it say anything about it requiring a specific version of stock firmware or specific version of bootloader to be already installed on the device "before" you do the rooting process described in the guide?
Sometimes these kinds of things require your device to have a certain stock software version as a starting point before the device is modified. Most of the time, if the device is ever updated to a newer version, the specific exploit that was being used to root gets patched in the update, killing the effectiveness of the exploit used to root. From that point on, chances of rooting are nil.

The vulnerability that CF autoroot takes advantage of may have been patched in newer versions of firmware.
I haven't been able to root any of my devices for last 4-5 years.

Yeah, I've been careful to download files in keeping with my specific phone, not just the G930V but the longer version of that model number, which seems super specific. Nothing works. I've tried three or four different versions of Odin at this point, but they all either fail or get stuck somewhere in the process. Probably time to start searching for a new phone. I looked around for other ways to root this s7 but i'm not finding much. I rooted the PIxel with Magisk.

I'm not talking about model number version, I mean the specific build number of the firmware that is installed on the device. Some guides/methods only work on specific build numbers of stock firmware or only work if a specific version of bootloader is installed on the device.

The S7 *can* be rooted, with lots of limitations afterwards. It just can't be BL unlocked

It could be failing due to the usb port or cable. I have an S8 that i can no longer flash only because I don't have a usb port in my pc old enough to flash it. I assume the S7 is the same way

I believe I do. I downloaded the firmware from lg-firmwares and the list it brought up all was for the CAN(Canada I assume?) region. But when I looked online at the official LG website the LM-G900UM2 is the Canadian model and the LM-G900UM1 is the American model I'm pretty sure. But I CANNOT find ANYWHERE a firmware that is specifically for the United States. Also, just for the hell of it, I even tried a program called SALT on the Linux Debian OS and here is some more interesting info I found about the phone...if it'll help at all.

Yeah for the most part, AT&T doesn't allow their firmware to be listed publicly anywhere - for any of their devices. So while the Canadian model may have the same base model number, I don't know if it will let you flash Canadian firmware to an AT&T device

Can you elaborate how or give me any info on a method I could try to successfully FRP bypass this phone then? You just don't know how much I would appreciate it. lol. I've tried and tried with so many different kdz's (of course for the G900UM) but to no avail. Also tried a couple different methods to bypass frp but, of course, no luck. Only reason trying to flash new firmware is to downgrade to Android 10 to bypass FRP. So... ultimate goal: FRP Bypass this phone! lol

Bump. Any news on this front I keep getting can't flash error na1_u=na6_us not allowed.

Frp locked lg velvet android 12

Hi I have a lg velvet phone that's frp locked is there a way to bypass it with out a computer and can I use a sd card to bypass it or even to down grade it from android 12 to android 10

No one replied yet? That's my issue also. I do have a computer. I think to downgrade it you need to pay for the software. But haven't gotten any real solution yet

You can downgrade it with an older dll from LGUP.Try this one!

It's crazy no one replied to doug for like 2 months. Have you tried downgrading and it worked?

I highly doubt downgrading will remove the FRP lock.There is 3 different versions of the Velvet.You have a 4g model which was never released in the states.The 5g devices have 2 different chipsets.AT&T/Verizon use the Snapdragon 765g which there isn't a firehose and the other is T-Mobile's MediaTek version.The MediaTek variant may be a little easier.I would personally try downgrading to A11 and see if it removes it.I don't think so,but worth a shot.I have seen some use Chimera Tool,and just reflash the firmware and it removes it for you.Most definitely you'll need a PC either way.You can search on Youtube and try some of those "so called" methods without a PC,but most I have seen are b.s. to begin with.Click bait!
