Sorry for the long read, this is half rant and half question.
Alright, I got a captivate a long time ago (about a year and 3 months ago), loved it, rooted it and installed cyanogenmod as soon as I got home, changed roms and kernals constantly, did whatever I wanted to do.
About 3 months ago my screen stopped working.. So I take it in and they give me a refurb captivate, looked brand new so I didn't mind. However, when I tried to get into recovery it didn't work, the 3-button-method just wouldn't work at all, period, so I try to get it to work, gets stuck in bootloop.. pretty much every time I try to flash a rom something goes wrong and I get stuck in a bootloop but I can usually get into recovery or download mode because I had CWM.
So I'm on maxq's rom and it's working great for the past 2 months, decide not to mess with kernals or anything, however today I decided to try ICS, load it up, everything's fine, then I realize my soft keys aren't working, search for awhile, can't find anything, finally just manually start looking through the rom pages, and someone said that if you have the problem to just odin back to stock and try again.
I odin back to stock, but now 3 button combo doesn't work.. So more searching, find that I can run the 3e fix by TRusselo, doesn't work because I need root, more searching on how to root without recovery, find "SuperOneClick", root with superoneclick, then run 3e fix, everything is working fine, I check my email and load the ICS files onto SD card, go to restart and go into recovery mode.. Bricked, stuck in a bootloop, won't go to recovery, won't go to download, nothing.
Why the **** was I able to do anything I wanted with my old captivate, but if I even root this one it bricks? And what did I do to even brick it? I only ran the 2 programs and both of them worked flawlessly.
I guess my only option is to usb jig it, but honestly now I'm convinced that the phone is just faulty, I want to run the thing over.

If you would have actually searched you would have known it was a bug in the glitch. There are atleast 40 pages about that.

If you flashed ICS you should know it takes 2 flashes for it to work first time. Having a jig around is always a good idea as well.

Stuff doesn't work as intended. Keep in mind everything is still in dev and not all devices are the same. But you should have searched a little more and it would have ran =/
U def don't need a jig. If it's booting it's not bricked. Try removing battery, start Odin, hold down power and down, plug in and put battery in. This should bring u to download mode.

I did start to see a few people with the problem, however many people do not follow up with what fixes their problem, and I did what a few people had said to do.

I understand that **** happens but honestly my old captivate could always get into recover mode and download mode no matter what, it's extremely frustrating that something changed with the newer models. One of my questions was what caused the brick? I did nothing wrong from what I see and it was running perfectly until I tried to restart/boot into recovery.
Oh and mbc663, thanks but download mode doesn't work at all, nor does recovery obviously.
I can't say exactly what you are doing. Best advice I can do Re download your .zips Flash back to stock GB and try again.

Last year, I had issues with my original Cap, and got a "new" one. I learned that the bulk of the Caps going out as replacements are referbs. The one I got was a 1008 build, and does not have 3 button recovery. There are minor differences with each and every Cap that's out there. That's why some have issues with ROM's and some don't, some can over clock like crazy, and some can't at all. My guess is you have a 1008 as well, but that really doesn't matter. You just have a different device and as you seem to already have learned.
It sounds like there is more research you need to do. Even though the devices are a bit different, if you are having issues with ROM's loading, then I would say it's more of a procedure issue, than one with your device.
My procedure, is,
Remove SD/Micro SD
Odin1 Click to Stock JF6, and Master Clear(This will erase EVERYTHING)
Root with One-Click Root
Use Sideload Wonder Machine to install ROM Manager, copy update.zip and 3buttonFix to my SD, then reboot into recovery
Once in recovery I install the 3buttonFix, and install my new ROM
For me this has proven to be a very good method versus going from one ROM to another. The Master Clear cleans EVERYTHING off of your SD, so there is no chance for anything to corrupt your new install. Anytime I read a post of a install gone FUBAR, USUALLY a Flash To Stock/Master Clear (FTS/MC) fixes it
Before using Odin 1 Click, check your devices build number!! If it is higher than 1012, I would NOT recommend using 1 click, there is a higher chance of hard brick on the newer devices
Kangi...if you flash a firmware package without bootloaders, you won't have to do the 3 button fix every time. And if you keep a copy of the update.zip on your pc you don't have to even root, let alone bother with side loading ROM manager.
Cezar has a no boots jf6 and after you run that, you can still use master clear in one click.
Sounds like you got one of the refurbs that is missing the SBL. Have you looked at this thread? http://forum.xda-developers.com/showthread.php?t=1129821
I've not had this problem myself but it sounds like that might help. If I remember reading correctly, once this is flashed it should stick as long as you don't flash any other bootloaders on top of it.
Its not missing the sbl. The sbl it has doesn't respond to key combos. Derpa sherpa moment for samsung I guess?
Rofl yeah...if it was missing the sbl it would be fuggin bricked!

I know, thanks. I'm such a creature of habit, I started doing it like this a bit over a year ago, and has worked flawlessly for me(just jinxed myself!) so I never saw a reason to "fix what aint broke".
I'll take a look at Cezar's thanks!
Yeah, missing SBL was a poor choice of words. My bad.

As for my build number, I'm not sure, the only thing I see under build number in settings is: "IML74k"

The build number is actually under your battery, and looks like 10.06, 10.07, 10.08 and so on. It is the production date
Edit** And as a side note, do NOT try to use the 3buttonFix with a GB ROM, it WILL brick your phone in a really bad way. ONLY use it with 2.1 or 2.2

Is it weird that I don't have a build number? It seems I can't post pictures without a few more posts, maybe this will work: deleted
And thanks for the warning on the 3buttonfix, I'm going to have to read more about bootloaders though, I don't understand what you and studacris were talking about earlier in the thread, haha.

(Obvious Noob warning---) A friend helped me root my Thrill, install ClockworkMod Recovery, and then install CM7 on my Thrill. But I would like to try the LG GB release. Is it necessary to backtrack all the way back to stock to do this (i.e. reinstall the stock ROM, reinstall the stock recovery, unroot, etc.)?
My friend tried using the LG upgrade tool on his LG phone without going back to stock and ended up bricking it. He says that usually within a few days of release, a CMR compatible zip file (usually already rooted) appears here on XDA (I haven't seen it), which makes things easier (but obviously he didn't wait for it himself).
Will a zip be possible for the Thrill GB? (The file seems quite large (420MB), so I'm guessing there is a lot of media included.) Or should I just bite the bullet and backtrack?

Trojan?
Sorry, but as a noob, I can't post in that other thread.
It seems that the shttp3.exe in the LG Flash Package triggers Symantec's trojan detection. Some searching seems to indicate (assuming I'm reading all the cryptic virus sites correctly) that there is something to this, although it seems that different scanners find different trojans/viruses (can't post the link, but Google for "shttp3.exe" and "trojan"). I also found that the web site for this utility is blocked at work, because it's a "malicious site."
Has anyone seen this? Has anyone been able to verify/refute this?

Just my .02 .....Get rid of Symantec !! They are known for scaring people into a virus frenzy.. Yes, it is possible that it is seeing it as a potential virus because shttp is a workaround from the usual porting of windows ip services. ...
Correct me if i'm wrong somebody please !!
Get yourself Comodo and save your money...
Regards,

PS: somebody on here has written a script that just uses shttp temporarily while
your doing the flash procedure, and then reverts your host files back automatically after your done. You should try it.

I'm sorry I can't give the link yet, but if you'll Google you'll see Comodo classifies shttp3.exe as "ApplicUnwnt.Win32.ServerWeb.SmallHTTP.~A" or "UnclassifiedMalware" (I guess depending on the version). A number of scanners find issues with shttp3.exe. I'm not saying it is infected, only that it is doing something suspicious.

shttp3.exe is in no way a virus. I've scanned with AVG and MalwareBytes Anti-Malware and they check out good.
Back to square one
OK, I seem to be stuck.
With paranoia in tow, I decided to take the long way back to stock. Unfortunately, when I tried to restore the backup of my stock image I made to SD card after installing CMR, the md5 checksum failed. I'm not sure what I can do about this.
So ok, I tried following the above link. The first step is to ensure the su binary is up-to-date. But when I tried this, I get a failure downloading the manifest. This is true for WiFi and HSPA+. I Googled and found a suggestion to delete the su binary. But that didn't help (I'm not sure how it would have helped anyway).
So back to the original question. Can I use the LG upgrade process to upgrade without going backwards (as you can see above, I can't) without bricking the phone? Can I start at step 3 in the link above and succeed?

Is it safe to ignore the su version update?
Short of this, can I override the MD5 checksum? I realize that image could be corrupt, but if I'm just going to replace it with the GB release, does that matter?

You should just put your phone in recovery mode and update through the tool
with your IMEI #. It will give you the latest update !
If you need some help on that I think Lestat or somebody has a write-up
on doing this.

Can you be a bit more specific?
1. By "recovery mode," do you mean into ClockworkMod Recovery, or I should revert to stock (I made a copy of it after I rooted the stock ROM, but before I installed CMR)?
2. By "the tool," do you mean the official LGMobile Software Update, or the LG Flash Package referenced in the link above?
3. By "latest update," do you mean the file directly from LG, or the copy (v20p) linked from the link above?
4. If the latter in both previous questions, which set of steps do I need to follow from the above link? Can I do only 3 (LG Flash Tool), or do I need to follow 1 (Recovery Manager), 2 (Returning to Stock), and 3?
My friend had a different LG phone, with ClockworkMod Recover and CM7 installed. He reverted the CM7 to stock, but did not replace CMR with the stock recovery. Then he used the official LG upgrade method and bricked his phone. I'm trying to avoid this.
Are you saying I don't have to worry about this on the LG Thrill 4G? Can I go straight from the current CMR+CM7 configuration to the LG GB release using the official LG process?
If you mean I should use a different process, can you point me to it? As I mentioned, I run into dead-ends using the method linked above. And I'm not even sure whether I should be doing steps 1, 2 and 3, or if I should just use step 3.
Any and all help is appreciated, but I guess I don't understand the shorthand you're using here, so if you could be a bit more specific, I wouldn't feel so lost.

Remove your battery and keep the phone unplugged
Launch the mobile updater tool
Hold the volume+ button plug the phone in and keep holding the volume+ till the computer downloads the drivers your phone is now in download mode
Once the phone is picked up go to customer support on the LG updater tool and click on recovery phone put your imie number in click check (make sure its the right model) an let the updater tool do its job. Once its done flashing launch into recovery volume- plus power plus 3D button do a complete wipe and factory reset and reboot your phone ... you'll lose cwm and root and be back to full stock

Bricked?
No joy. Following the steps, the upgrade stopped at 6%. Trying a number of times, it eventually forced me to exit the program (no more restarts). Rerunning the updater (and downloading the 420 MB image yet again on a VERY slow connection) I tried again and again, with different combinations of battery and plug order with power and volume buttons, but nothing worked. Checking elsewhere I found some issues had been reported with Windows Vista/7, so I tried on an XP machine. Now the "Start Updating" bar is red (it was always gray with W7). But now when I try to restore (or even update for that matter), it asks for my S/N (it never did that before) and then says it is "no longer able to upgrade." Reading around, it seems this is an indication of the device being bricked.
Rick
It sounds like you are very close to getting it working Rick.
My update did the same thing, looped over and over until it
finally kicked me out. Just plugging and unplugging the phone etc....
And when my update stuck at 6% the last time, i took my battery out and then in real quick and that seemed to work.
Does the phone still vibrate when you plug the usb cable into it while holding volume..? If it does then I highly doubt that your phone is bricked, just in a semi flashed state....No worries
Should Rick be trying to run LG Updater as administrator ? I didn't, but it might not hurt.

It never really vibrated, but I was able to get back into CMR. Unfortunately NONE of my backups work at all. They all have MD5 checksum failures. I tried a trick I found online and got past that step, only to have it say a failure restoring /system. So much for CMR.

Which step? As I mentioned above, I can't even get the first step of the first section (updating the su binary). And if I start at the 3rd section, Symantec prohibits me from using shttp3.exe (I tried to unquarantine it, but it gives a permission error, even as Administrator, when I try to run it), so I'll have to use a different machine.
I was able to reinstall the CM7 3/15 release, so that's something. I was going to restore the stock recovery backup I made, but even that doesn't seem to work. I'm having issue with backups :-(
Rick
i have never been able to restore a backup. i dont know why... but i have tried several times in several different instances.

New Revo won't work with A I O, can't stand the bloat someone tell me please. Is anyone working on a root for this POS update.
oh im sure
im sure MT is on the job, but im sure a lil donatin to him would motivate him a lil.... but yeah anyway the thread "keep root through zv8" or whatever is still the only way that the general public knows about... but im sure u already knew that.
I figured as much about MT, (your the man) but i ask because my old revo worked fine with his AIO and maintain root method, but the new one i got that came pre-loaded with Zv8 wont, even after flashing several times back to zv7 and so on.
If you're readin this MT i am to poor to donate money but im willing to be a guinea pig. lol

There is something you aren't doing right even if on ZV8.. You can downgrade to ZV7, then Root only with the original AIO, then create the local.prop file then download the update, then use the 2nd AIO to maintain root, install CWM, then Broken Out.
I'm inclined to believe you because aio worked the first time but then zv8 would fail to regain root and install cwm it would say failed to find path, then flashing back with .tot to zv7 and even doin a factory reset back to stock and trying again now aio won't even root zv7 it just says failed to find path and runs through real quick, if you have any suggestions I would appreciate them.
And by the first time I mean I flashed back to zv7 rooted, flashed maintain root then ota updated then zv8 aio would fail
I have tried many processes over and over again and can recall once the first all in one wouldn't root my phone. I just did a factory reset then after reboot ran the lg-setup then flashed the v7.tot again then was able to root only after that reboot.
If that doesn't work, I don't know what will but good luck
Yah tried that, no luck, well see what mt comes up with. This is a new recertified phone and it has some wierd usb issues, everytime I reflash I have to reboot to be able to use change usb connection, plus now when flash tots I dont lose phone settings like I used to,
i have money!!!!

Money is something I have, root, I do not. It sounds like MT is the man when it comes to rooting. I would be glad to make a sizeable donation thru pay pal if I knew it would go directly to helping me game root access for my lg revolution running zv8.
See I would do the downgrading option everyone is talking about but those methods are only for pc ( I mean those download files ). I run a mac.
But seriously, I would love to have root. I used to use an iphone and was always jailbreaking. I love having that type of access so any help would be awesome!!

That means nothing. I flash TOT's all the time and never loose settings or apps.
As for MT developing a root process for this phone, while I appreciate all the work he has put into this phone and his skill set, what he does and what root exploiters do are two entirely different things. MT is just gracious enough to create easy to use AIO scripts for everyone to use. I do not see a new root process coming unless another exploit is found and works on this phone.
If I am incorrect about this then MT can feel free to correct me.

+1 For root all I have found is the exploit for keeping root through the update. As for writing a fresh exploit, there are a couple of guys that specialize in it. Jcase and djrbliss are 2 of the best around. The only problem I see is that zv8 has 0 access to the data partition without root, and so what other partitions are blocked. That is why the spectrum version does not work right off of the bat.

nevermind, just had to push cwm through adb still don't know why aio zv8 failed oh well im good now, and mt thanks for debloating and debingin. lovin broken out
Well I THINK I have found WHY I cant OTA ZV8
OK. I have found somthing interesting. I have 2 Revos. BOTH are now in test mode for reasons I am to embarrased to go into. (dang Noob screwups)
ANYWAY I was playing around in LGNPST last night and discovered the Warranty Date (assuming Expiration) on one phone was 4/4/12 Ironicly the same day I unbricked it using the Phonebook emergency recovery. (what puts the the phone in test mode. )
BOTH phones are flagged in my Verizon account (VZW online) as NON VZW Phones. (even though they originally were)
I am starting to think that when you do an emergency recovery you flag not only test mode but the warranty date & some Verizon flag as well. So while the phone is functional ALL Verizon support goes Bye Bye (I.E. OTA updates) EVEN if you flash back to Stock. I know that none of my old Not so smart phones will update past the Warranty date, I suspect this might be somthing similar.
Can anyone VERIFY this? I can SEE the potential problem but my skills stop there. (for now.) Can anyone tell me how I might be able to dig deeper?
I'd be happy with a rooted ZV8, let alone broken out, at this time.
I dont think anyone has figured a way around test mode yet except flashing back to zv4.
If it doesn't boot after flashing .tot:
1. Pull Battery and replace
2. push power and down until you get option to wipe
3. press power to confirm and reboot.
you will be stuck in zv4 and any flashing forward after that will put you back in test mode but at least you will be able to use your phone like normal until someone figures this out, but from what I read it appears improbable.
Yeah not looking good. Test mode I can live with it's the other issues thats killing me.

If you downgrade to Zv7 so you can root install cwm and eventually get to rooted Zv8 you will not lose anything on your phone if you do it correctly.
Just Flash the Zv7 Tot and use mt's AIO method, (stopping short of broken out)
if done correctly you will lose nothing.

Using this guy's guide for the Nexus 5 I had no issues, bought a N6 today and was giddy to flash on Cataclysm for N6 and figured might as well use same person's guide for next phone up.
http://www.androidrootz.com/2014/12/how-to-root-nexus-6-windowsmaclinuxubun.html
Was able to unlock bootloader, then installed TWRP but now am getting the 'corrupt phone' message, however unlike others like I have read on XDA, am unable to boot up by just letting it sit. Screen turns off and that's that. Before beginning entire process I enabled "enable/allow oem unlocking". I'm assuming that when the phone factory resets after the bootloader unlock I need to go back in and recheck 'allow oem unlock' in dev options, but I didn't as I assume/ed that it wasn't necessary and the guide doesn't tell you to.
Tried relocking the bootloader to maybe get phone to open up, but terminal tells me that I need to have 'allow oem unlock' checked. Nice Catch-22 http://puu.sh/moOUf/d0f8fa9050.png
Tried formatting data from within TWRP and factory resetting/wiping everything but it tells me that it is unable to mount '/data'
Have since tried WugsToolkit and flashing to stock with 'softbricked' option enabled the shamu-mmb29k-fact....tgz image that I downloaded and imported myself into Wugs (was taking 10 minutes to dl 1%). That seemed to work and told me it was a success, however when I then went back to re-enable the bootloader via wugs it fails and reboots with the lock sign still open and boots again onto 'corruption' screen that then flashes off and turns phone off, left it for 30 minutes at one point and didn't boot so don't think I'm lucky enough to be able to sit if through like others who had that issue
Where to go from here? Really hoping I didn't brick this phone less that 3 hours after getting it. I can still boot and see the Google screen and can get onto the bootloader and used to be able to get into recovery (since wugs have been getting the android with red triangle)
Been rooting/rom'ing since day one that I've had androids. Had a Samsung Apollo with CM on it, same for the Nexus S, then the Galaxy Nexus, then the N5 and looks like my chain of no issues ended tonight
Anything you can do for guys would be greatly appreciated. No clue where to go from here....
So from what I gathered, I think you are in luck. It sounds like your bootloader is unlocked. This is a very good thing. Under no circumstances do you want to try to re lock it right now or do you ever when stuck not being able to boot or any issues like that. If you lock it while stuck, thats when you are soft bricked. If I remember correctly, I got myself in the same situation , although maybe with out a custom recovery installed. None of that matters though. The way to fix this is to reflash the the factory image. Here are the guides for that.

and lastly here is an xda post http://forum.xda-developers.com/nexus-6/general/guide-flash-factory-images-nexus-6shamu-t2954008
I would recommend reading and watching all of these and maybe doing more research so you really knows whats going on. The flash-all script is not going to work from what I've read and I've always done it manual so go with that. It may also be a good idea to keep the custom recovery, so look into to keeping that. Maybe it is as simple as not erasing the recovery partition and not flashing the recovery image. This is what should save your nexus.
Now, I am fairly new to the Rooting and ROMming, really only started 2 months ago, so I would really appreciate if any of the more experienced guys on XDA can confirm what I said. Please don't try any of this without confirmation from another member here, I do not want to be responsible for sending your device past the point of no return. I recently had to order a new Nexus 6 as the screen is dead, so I know it's frustrating to have that loss. In your case, as long as that boot loader is unlocked, you should be safe. Best of luck to you.
DO NOT RELOCK THE BOOTLOADER!!!!! I cannot emphasize how critical it is that you do not relock the bootloader, given the position you are in. If you somehow manage to relock the bootloader and "enable OEM unlock" is toggled off and Android will not boot (even after attempting a factory reset), then you are 100% bricked with no way to fix your phone. Personally, I leave my bootloader unlocked 100% of the time so that I can fix anything that may go wrong with my phone. Additionally, I (as well as many other users on here) will always advise against using Wug's or any other toolkit in order to do stuff to your phone. While they do provide a nice GUI as well as an easy way to install the necessary drivers, using the regular platform-tools command line method isn't all that hard to figure out, and it allows you to know exactly what you have done to your phone. With Wug's and the like, you never really know what commands that they are running and exactly at what point in the process a flash may fail. Right now, I would advise you to read up on using the platform-tools method to flash stock images. After you have all of the necessary drivers, platform-tools, etc. working properly on your computer, I would strongly advise that you download MMB29S (the latest official update) from the Google Developer page and flash it using the platform-tools method, NOT with Wug's. And whatever you do, I repeat, DO NOT LOCK YOUR BOOTLOADER!

Regarding the flash-all script, my friend and I just used the script included with MMB29S and it worked fine. In addition, I was able to use the one with MMB29K, MRA58K and MRA58R, all of which worked fine. I'm not sure if these scripts always work for some users and never work for others, but I always recommend that people who are new to flashing simply try them, as they are quite convenient when they work. In addition, I have only been in the rooting and ROMing scene for about a month or two as well, but I would consider myself pretty seasoned by now considering all the different ROMs, rooting methods, etc. that I have tried. All the advice that you gave to the OP is excellent and I agree with it all.

No problem! It's too bad to hear about your device but at least you got a new one on the way. There is really no harm to at least trying the flash-all script. It will either work and save you time or fail halfway through and force you to flash everything manually.

You guys are life savers, thank you so much
Got it to work after I was getting ready to phone it in and bring it to a repair shop and eat whatever the charge might've been
Hi everyone,
Please forgive any n00b questions.
I got started with rooting / custom ROMs on a Nexus 4, and I didn't realize at the time that this made things really easy and I didn't need to learn very much about how everything worked. Fast forward to last week -- I decided, at long last, that I was tired of using stock MM on my T-Mo G4 / H811. How hard could it be? Probably not much different from playing on my old Nexus 4 right? Lol, maybe not.
So now 72 hours later, my phone is hard bricked and will not enter download mode. and I need some assistance, if anyone would be so kind.
I will try to recount what I did:
To start with, I was using a Mac, so I used Homebrew to install Android platform tools / ADB.
I decided I wanted to try out LineageOS so I went ahead and followed their very clear steps (on LOS wiki) to unlock the bootloader install TWRP. However, TWRP doesn't seem to have an official build for the G4(!) so I had to look up and use one of the betas from this post. Is this where I went off the rails already? [Of course, very stupidly I also failed to make a complete backup of anything before going on ahead. Rookie mistake.]
After unlocking bootloader and flashing my TWRP beta, I was able to boot into TWRP just fine. I followed the normal prescribed steps of doing a Wipe (normal TWRP defaults -- system, cache, etc.?) before flashing the latest LOS nightly (14.1-something) and also the nano-x64 variety of gapps. I rebooted and got stuck with the LOS boot animation. I let this go for 55 minutes, so I am pretty sure it was an actual bootloop, not just the 1st-time-startup and optimization going on.
I rebooted into TWRP and decided to try a different ROM to see if that was the issue. So I wiped again, flashed another ROM (I believe it was a flavor of AOKP 14.1.x), flashed gapps again, and gave it another try. Again got stuck with an endless bootloop (45 minutes).
Since this is my daily driver, I decided to go back to stock. Found this thread, downloaded the MM-debloated zip, pushed to phone, and again Wiped + Flashed. This time, when I hit reboot, my phone was immediately hard-bricked. No startup screen, no nothing. That was quite unexpected. Also, the first time I had ever HARD bricked a device that I was playing with. Yikes!
Since then, I got a hold of a PC, and have been trying to revive the device by flashing an image to the microSD and booting into Download mode, in the form of this thread or this one.
I did get this to work briefly yesterday, or at least I got to Download Mode / Firmware Update screen, and then attempted to run LGUP with the KDZ file. However I ran into an error at about 9%, and couldn't continue -- and then I had to give back my loaner PC for the day. I also noticed that the LG Mobile Support tool was recognizing my phone NOT as an H811 but as something like HX230 or ... whatever it was, it was definitely wrong. Which is worrisome.
Today I'm giving it another try but my phone will not enter Download Mode at all, nor respond in any other way. I'm curious if this is a battery issue? So I am simply charging it for the time being. I also re-formatted the microSD and re-flashed the single .img just to be safe, but still can't get a response out of the phone. On my PC's device manager it is showing up as the common Qualcomm 9008 that a lot of people seem to have seen. No recognition from LG Mobile Support tool, nor from LGUP.
So ... what now?
It's possible that once my battery gets some charge again, maybe I'll be able to enter DL mode. Let's hope so.
However, I am also totally in the dark about which software version I should be using. 20i? 20p? I have no idea what these refer to, and I did not make any prior notes to capture the state that my phone was in before this all began. So IF I get to DL mode I will definitely need further instruction on the CORRECT KDZ FILE to be flashing. Else I will just compound my problems.
ANY tips or suggestions will be appreciated! Thanks so much.
Should have verified being on 20o firmware
Upon further reading, quite obvious, at the top of this thread, I definitely should have followed the Prerequisite steps. I did NOT verify that I was on 20o firmware. "OR RISK BRICKING YOUR DEVICE" is right.
So I bricked my device, in exactly the way I was warned not to do, it seems.
Still, what's the next step? Any thoughts?

Ok what was the last KDZ file you flashed which had worked? 20o?
As you have hard bricked your device you can try the sdcard method again if it works flash 20o again (of it it was 20o).
If you flash a lower version you will hard brick again.
If the sdcard doesn't work anymore for you you can try to flash with QFIL but beware to use the right one. If you use the wrong one it will convert your device and believe me that's not what you want. I can share the good ones but unfortunately maybe on next week first.
Otherwise search on your own for 9008 unbrick but check the md5sum of the programmer!! Compare it with the Evil one mentioned in my ARB list here: http://tinyurl.com/antirollg4 and DO NOT USE THE EVIL one..

Thanks very much for the guidance! The post that you linked to REALLY helps. Until now I really was not sure what 10n, 20i, 20o, etc. referred to, aside from just various software versions. Having a definition for anti-rollback and further links to explain, really helps! This gives me more information and I might be able to self-resolve from here. I will give it a shot.
As for your question ... unfortunately there was NO instance where I flashed a working KDZ file, and I didn't know (due to my past experience with my Nexus) that I needed to check the STOCK software version of my phone before beginning to play with ROMs. In other words, I have no idea if I was on 20i, 20o, 20p, etc. From what I understand, this makes things a lot more difficult
Having looked at the linked thread just a little bit, it appears that using a 20o KDZ is the best bet -- because I bricked my device using a 20i ROM so I expect it was due to violating the anti-rollback restriction.
I will look into it more closely and come back if I hit another brick wall. Thanks so much!
If anyone cares, here are the ending results of all this ...
#1 Be wary of anti-rollback restrictions before you flash anything to your G4. You WILL brick your phone!
I tried multiple rounds and multiple variations of all the MicroSD card methods that I could find. I could NOT succeed in unbricking my phone.
#2 Luckily ... I was able to convince LG that I was still technically under warranty!
Because I had the stock bootloop issue in May 2017, LG did an in-warranty repair for me, and replaced the motherboard. So last week, I simply told them "my phone is AGAIN unable to charge and will not power on, just like in May". Since it had only been 5-6 months since the first issue, they agreed to replace the motherboard again.
Moral of the story: you can definitely unbrick your phone by having LG replace the mobo XD XD
From here, I think I will just totally avoid doing any rooting or custom ROMs on my totally-stock G4 coming today in the mail. I will cross my fingers and hope we get OEM Nougat in the USA sometime in the next couple of months.
Thanks again for the help everyone!
