LG G8 ThinQ No Command Boot Loop? (At&t) - LG G8X ThinQ Questions & Answers

So as the title says, my phone is stuck with a no command screen and i think it is going through a boot loop along with it. so hears the backstory. Its a used phone, bought through Facebook [not such a great idea, but i bought a note 10 last year for half the price brand new, cant win every time though]. the seller failed to mention that it was rooted. and in a haste one day i deleted my conversation with him (not archived) when i was cleaning out my messages.
When the battery died i saw the first warning, stating "Your Device software cannot be checked for corruption. Lock Bootloader. Visit this link on another device: g.co/abh" that's when it got stuck in a boot loop. It may have received a update, im not sure. I visited the link which is for google pixel or nexus phones. so i brought it to a repair shop and local businesses will not work on it, because its been rooted. well i managed to get it working again, only by doing a factory reset. Ive had to do that twice. then one day i magisk had a update. i did it. and YAY its fixed. me being me wanted to unroot and lock the bootloader so it would be back to default. Nope. I uninstalled magisk. and boom i have the no command boot loop. i have tried using the LGUP program, but with it being att that got shut down real fast. I have looked all over for information. but i need it dumbed down. I catch on quick but a lot of the terminology is lost on me. I may have forget to mention some things. so please anyone who can help. any info would be appreciated.

So after much button combos and almost just chunking the phone. I managed to get it into download mode. by pressing and holding Vol- and Power button to get it to restart. (phone is unable to power off. unless the battery is 0%) While screen is blank, press and hold Vol+ while plugging usb into the phone. I had the cord in the computer first. it may work vice versa. Looking for AT&T official Firmware now. I think.

Brother, I request you. Please tell me how you did that.
i cant do anything. i have the exact same problem
Please guide me step by step.

[Q] Need help fixing a possibly bricked Optimus V...

So I rooted my sister's optimus v about a month ago. Today she installed a battery mod app from applanet and as soon as she chose which battery mod she wanted she had to restart her phone for the changes to be applied, but when rebooting the phone it would only get stuck in reboot. So I tried to start it up in recovery and got the blue screen that says fastboot mode started. I looked that up online and found a fix to it but I need it to go into emergency mode to fix it that way and it will not go into emergency mode, any combination of keys only takes it to either the blue screen with the fastboot mode message or it just reboots and gets stuck. So now what do I do? I really need to find a way to fix her phone. Thanks in advance to anyone who tries to help.
try to turn on the phone & use LGMobile update tool. That should recognise the phone & install original lg fw

I managed to finally get the phone into emergency mode. I had installed the LG mobile support tool and installed all the drivers and tried to go that route but it kept telling me I only had one of four drivers installed, even though I have installed several drivers. After all of that I had finally got it into emergency mode so I went back to trying KDZ. I'm supposed to select the rom where it asks for the KDZ file right? But when I go to browse for the rom file it doesn't show up in the folder I put it in. I've rooted 4 phones and have done so many other things with them and never bricked one, was always able to figure out everything I did and never had to ask any questions but I can't figure this out to save my life and it is driving me crazy. I do really appreciate you guys for the suggestions and thanks to your suggestions I have gotten this far.
Hey, I have the same problem. I rooted my phone then I installed that battery mod app on applanet. I installed it then when I had to restart my phone for it to apply it just got stuck and kept looping the reboot screen where it says "ANDROID". Did you get ur fixed yet?

I'm having the same issue right now, although at least you have managed to get it into emergency mode. How did you do it?
The other issue I'm seeing is that there is no .kdz for the Optimus V LGVM670. I found a .cab file that is supposed to be the newest update, but not even sure that will work with the the kdz manager.
It was my sister's phone and I had the same problem with kdz. Had the cab file so couldn't use it with kdz. My sister left her phone with me for a few days to try to fix it and when I couldn't she took it home and managed to fully brick it to where it would do nothing at all so she had to get a new phone. I got it into emergency mode by holding down the volume and it was either the back button or the home button I pushed at the same time, can't remember which. As I held those down I plugged in the USB cord that was connected to my laptop and it went right into emergency mode. Just make sure you disable that LG modem in the device manager on the computer before doing anything because my sister forgot to do that and that is how she fully bricked her phone. Good luck to you guys and if anyone figures out how to fix it I would be interested in knowing how you did it.

hmmmmm, I don't remember completely how I did it, but there was a very helpful guide floating around XDA. I bricked my Mom's Optimus one as well . I actually had to go to the LG support site, type in my Phone serial number and find a list of all the firmware available. From there I right clicked the page and got the page source. From there I got my firmware and I entered it in the KAZ or LG B2I Agent ? - Dont quite remember. Anyways, it ended up working out for me, but I accidentally flashed the German firmware, but in the end, everything was all good LOOL.

[Q] trying to revert exhibit II to stock

hello xda. been browsing for a couple weeks, but finally registered today.
I have run into a problem I would like to try and solve without having to go through my insurance or carrier. my phone bricked itself after only 16 days, with 0 modifications on it. it was factory stock still. let me describe what happened, and what I did:
1st problem: I was using my online banking app (reputable bank), when the app minimized to the main screen; however, nothing OS related loaded. the phone just froze. only the wallpaper was visible. I tried powering it down, but it wasn't responding, so I pulled the battery, and put it back in. I powered on the phone, it loaded the SAMSUNG screen, then went to the Exhibit II 4G page, but then it stopped. it failed to load past the Exhibit II splash screen. no matter what I did, it stayed there. I googled for hours, trying various things, until I finally found this site with a stock rom setup.
2nd problem: I followed jocala's guide for flashing it, using Odin 4.43, and after it finished flashing, I got a "Firmware upgrade encountered an issue. Please select recovery mode in kies & try again." so now I have been googling this issue, and I cannot seem to find anything on how to fix it. I don't understand how my phone can just brick itself while using a banking app that i'd been using since I got the phone.
any help would be appreciated
also, if this isn't the forum for it, feel free to move it. this just looked the most appropriate seeing as there wasn't a board for the phone specifically.

Howdy, DBNP,
The Exhibit II is pretty much unbrickable...you won't need to resort to esoterica like jtag
The guide in the Exhibit II Wiki usually works out well. I'd try booting into stock recovery, doing a data wipe, then install stock with Odin. The Wiki has the links to the files you need. BTW, I didn't write the Odin portion @ the wiki; I just hosted required files when the links went stale.
Easy way to start recovery
* Pull the battery from your phone.
* Connect phone to your pc via usb.
* Press & hold Volume-up
* Insert battery
Once you're back up and running first thing you should do is install Clockworkmod. HTH, & good luck.
I cannot get my phone to get into recovery mode, though. if I press volume+up, the phone simply displays the firmware error message. thus, I cannot do a data wipe.

Sorry if this is redundant, but this was with:

This has never failed for me. IDK, Perhaps your earlier Odin try wiped the recover partition. Can you get into Download mode? (hold Power-on Vol-Down)
I can enter download mode, but I cannot enter recovery mode. volume down gets me into download, while up gets me the error message. I cannot get to that menu anymore.

Are you saying that you get an error when you press Vol-Up at the initial "Warning!" "A custom OS can cause..." screen, the initial download mode screen?
when I press and hold the vol-up sequence, it takes me to the initial error of "firmware upgrade has encountered an issue..."
when I press and hold the vol-up sequence, it takes me to the menu where it says custom OS etc., press up to continue, down to cancel (restart phone).

OK, that's good. That tells us that your exhibit2's /dev/block/mmcblk0p5 partition is undamaged. AFAIK Odin when properly used, can flash a new rom to your phone. Please try again, following the instructions in the wiki, reading carefully, downloading any files that you need, if you don't have them. Please walk through the wiki procedure to reflash stock from Odin, this procedure has worked for many,many people. Keep careful notes, you may be an edge case for some reason.
I'm posting links to this thread in the discussion threads that we use, since we're not allowed a forum. These threads get the most attention.
Exhibit II 4g discussion HERE

yeah, I have tried doing that myself, as well as my friend who is rather skilled with android devices. he tried that all himself today, as well as attempting add. nothing worked.

I think you and your friend did it wrong. You should try again, following the wiki carefully.
we re-did it this morning step-by-step with no new results. we tried three times.
odin does its thing successfully, then when it goes to reboot, instead of going into recovery mod, it just goes to the firmware upgrade issue message.

Sorry to hear it. If Odin won't fix your phone and you've only had it a few weeks, I'd return it. I've linked your thread to our discussion threads, perhaps someone else has an idea.
that's the issue. because I have tried to flash it via odin, they're saying they won't take it because of the firmware upgrade error that keeps coming up. :/
because they won't take it, and the normal flashing to stock method isn't working, what do you think I should do next?

I don't know who "they" are, but the chances of anyone at a T-Mob store or a Walmart knowing you touched your phone with Odin or even what Odin is are practically nil. "It's three weeks old, I turned it on and it doesn't work. Gimmie my replacement."
Or seek out a repair service to reflash your phone.
all right, i'll take it back and get a different rep. thanks for your help, though

go into recovery and do a factory reset then reboot from recovery.

[Q] odin failed, flash recovery.bin cwm

i was trying to root a phone for someone and after odin completed it said it had failed.
the phone is a telus samsung t959d running froyo.
I followed the instructions from (I would post the url for the link but i am not allowed to.)cyanogenmod's wiki, after it failed I rebooted the phone and it got stuck on the screen in the attached pic. I have tried to boot back into download mode to no avail. From the screen it's stuck on I cannot get any tool to register the device as being present, adb, heimdall, zdiag, etc... I even tried fastboot out of desperation.Before I used odin I tried to get the phone to boot into the bootloader but it only ever went to either recovery or a normal boot and I tried every button press combo I could think of and found and nada.
Even running adb reboot bootloader just made the device boot normally. I think that if I could get it to boot to fastboot usb i could then try fastboot. I am new to rooting devices and have successfully rooted my HTC EVO3D and got s-off and simlock removed for any carrier. So I do know how to follow instructions properly, why flashing the recovery.bin failed I don't know and every fix I seem to find says BOOT TO DOWNLOAD MODE. if I could do that I wouldn't be having this problem lol. Anyway can someone please help me figure this out. Thanks. ANd if you need any further info please let me know. I don't want to have to give my friend my phone due to a software issue.
And YES I did pick PDA not anything else.

I kept reading other threads and sadly I din't pully the battery first before disconnecting the usb and repartition may have been checked as I see that it does the as default for my version. Also i turned off ODIN as I was hoping a reboot of my computer might help. I will keep trying to find an answer till someone gets back to me. this post may not even show up if I can't do a second post if no one has replied first.
Everyone was a nub at one time wasn't it FUN hahahahahaha sob cry

I tried a jig and that didn't work. There must be some way of getting the device to give up on completing a task i no longer can give it due to ODIN being shut off.
Why is it that the "how to root/unlocks" never have the "if x fails then do these steps etc..." Had the how to had "pull the battery before disconnecting USB and don't reset or shut off ODIN" I wouldn't be in this mess. I realize that it's user beware but a few important steps like that in case of a fail would go a long way to you guys not shaking your heads. Instead of "silly nub hahahahahaha". No offence but I get that a lot and try to remember that when I teach someone how to use a computer. I am new at phones not at everything.
Further Developments Please can someone help?
I was giving someone a new memory card and they had a Samsung SGH-I896 it has an EB575152VA battery and the one I have the T959D has an EB575152VU battery. I exchanged my battery for hers by accident somehow and when I plugged my phone in it didn't go to the phone triangle computer logo screen it booted to recovery and said it couldn't charge the battery and kept rebooting to recovery. I got my battery back and it booted back to the phone triangle computer logo again. Grrrr....
The other thing I saw while the recovery screen was an error message that said
Code:
E:/data/fota not accessible
(may not be 100% accurate I don't have the battery to check right now but can get it again if need be) anyway I now see that there may be some light at the end of the tunnel. i have the correct stock firmware for the device I tried flashing it while in recovery but the phone kept rebooting before anything got done. My question is how can I get the dang phone to stop asking for Odin and go to recovery so I can flash stock firmware and ROM back to it? As I cannot as far as I know give it what it wants because I reset Odin and nothing seems to see that the phone is connected to the computer. I am going to try the other battery on a full charge to see what that does.
I am new at all this and want to get it fixed. I cannot afford to send it off to a service center and besides that I want to do it myself as I want to become a developer and droid technician. I would gladly donate to anyone but am still trying to get Google to accept my pay-as-you-go credit card and I don't have PayPal either. Which is really frustrating when it comes to giving back. I posted a Q&A on how to without PayPal or CC but as of the last time I checked no one has gotten back to me about it.
The CyanogenMod guide is flat out WRONG. I've tried to change it, but anything I do is reverted in an instant. I also tried to use it to install the ROM only, ended up bricking my phone and it took me hours to unbrick. That's how I became acquainted with XDA.
So, to get this straight:
1. you're using the stock USB cable
2. you remove the battery
3. you hold volume down
4. you plug in the usb cable
5. after a few seconds, you release volume down
6. the screen does not display a yellow triangle with an android

That is correct. If you think that my idea below is a bad one or if I downloaded the wrong firmware package please let me know and /or you have a fix that will work? ty
I have though come up with an idea that may work. I am going to charge the "wrong" battery in erm the right phone lol and then use it to trick the device into booting into recovery instead of the cellphone triangle computer (CTC, for want of a better acronym) The I896 battery ends in a V not an ? (sorry can't rem don't have it on me) from the I896 model I think it is, plugging it into USB with the power off sends it to recovery with the "battery cannot be charged " message instead of the CTC screen.
I tried it but the charge in the battery was too low and rebooted. I am hoping that with a full charge (as long as I don't power on the phone first as this will make it go to CTC logo again.
I am hoping that I can install the update.zip that I made by first unzipping the T959UVJFD_firmware.tar I downloaded then unpacked and then repacked into an update.zip as I don't think that it will read the package as a tar file and if it's not called update.zip The recovery is still stock. If I get the phone working I am not going to try unlocking and rooting it again. I will just post two separate adverts one as a carrier locked device and the other one (higher of course to cover buying the unlock from Telus) as carrier unlocked and then I will buy the unlock code if the blah blah you get the drift. sorry for rambling on.
oh and I can't rem if I said this or not, In recovery it "E:/data/fota not accessible" I don't know what that means yet I have been busy with other things and haven't looked it up yet.
Since you can get into at least some version of recovery, your bootloader is intact and you should be able to unbrick it. You ought to be able to get into download mode using a download jig. You can get one on ebay for a few bucks or you can make one yourself. There's a guide floating around here somewhere that lets you make one from a microusb cable.

[Q] I believe I am bricked, can anybody help? (p769)

Before the incident, I had root, no unlocked bootloader, stock JB, v20h.
What had happened was I was trying the Font Installer app in th Play Store because of the added customization that would have been nice.
I found a cool font, and I backed up my current fonts and then pressed install. SuperSU asked for permissions like normal and then my phone restarted.
Then it was so that my phone was stuck at the T-Mobile boot animation after the LG Logo. For about 15 minutes. This is where I believed something was starting to go very wrong. After contemplating for a few extra minutes, I decided to just take out the battery and restart. Same outcome. I thought of all the things that were on the phone thus far because I had just gotten it recently, and decided that it wouldn't hurt me to just do a hard reset by pressing home + vol down + power. Everything went smoothly. Except for the fact that even after I did that, it was leaving me at the T-Mobile screen.
I decided to look on the forums for development and tried to do the unbrick method, to no avail after about 3 hours now. I used the LG User Support Tool and since I hadn't updated to V20f, I decided to do that to see if it would solve my problem. It still didn't, and I'll be honest, I'm a little upset just typing this right now.
I also tried the Upgrade Recovery option and it warmed my heart to see that the process was actually starting. But right at the screen where it says that it is supposed to be downloading something, it freezes up and nothing happens no matter how long I wait. I saw somewhere that it should be a glowing red bar, but I do not see that anywhere, it is just frozen, saying Time Elapsed: 00:12. And before anyone asks, yes, I ran absolutely everything as an administrator.
Is there any possible way to bring this phone back? Any help would be immensely appreciated. Thank you in advanced.

Then it was so that my phone was stuck at the T-Mobile boot animation after the LG Logo. For about 15 minutes. This is where I believed something was starting to go very wrong. After contemplating for a few extra minutes, I decided to just take out the battery and restart. Same outcome. I thought of all the things that were on the phone thus far because I had just gotten it recently, and decided that it wouldn't hurt me to just do a hard reset by pressing home + vol down + power. Everything went smoothly. Except for the fact that even after I did that, it was leaving me at the T-Mobile screen.
I decided to look on the forums for development and tried to do the unbrick method, to no avail after about 3 hours now. I used the LG User Support Tool and since I hadn't updated to V20f, I decided to do that to see if it would solve my problem. It still didn't, and I'll be honest, I'm a little upset just typing this right now.
I also tried the Upgrade Recovery option and it warmed my heart to see that the process was actually starting. But right at the screen where it says that it is supposed to be downloading something, it freezes up and nothing happens no matter how long I wait. I saw somewhere that it should be a glowing red bar, but I do not see that anywhere, it is just frozen, saying Time Elapsed: 00:12. And before anyone asks, yes, I ran absolutely everything as an administrator.
Is there any possible way to bring this phone back? Any help would be immensely appreciated. Thank you in advanced.

did you hard reset? then turn off your phone disconnect the battery, connect to the pc holding the volume up button? then try the Update Recovery?
i would just go through that process over and over until it works, theres not really a way to brick this phone i've heard...

Thank you for your reply! I have tried hard resetting multiple times, but I had removed some bloatware apps (I will quarantine them next time instead because I don't wanna go through this ever again) and I have tried the kdz method to only be stuck at 15% every time when I followed instructions to the pixel. I have tried to do it on windows 7 and windows 8. I have also tried the fastboot method by lelus, and that manages to "work" but I am still stuck at the tmobile boot screen afterwards. I have gotten the hang of the process of getting into the fastboot, but what do I do from there? I chose to flash ics xloader and uboot, but the process goes by so fast, I'm not even sure it is doing anything. The LG Tool has really gotten me nowhere, it just gives me a lovely error and then cannot continue the upgrade recovery process.
It said somewhere that after I flash through the fastboot I then have to try the kdz method, so I am going to do that now and see if it works. I don't know if there would be a difference between flashing a jb kdz or an ics kdz, but I will just do ics to be on the safe side.
I am quite happy to say that flashing the ics kdz was successful, and my phone is now up and running.
My p769BK is stuck on the LG screen. /: months
Sent from my LG-MS770 using xda app-developers app
im terrible with fastboot, i used the unlock the bootloader for noobs with an offline flash.
heres what i did to get out of bootloops....
alright, this is all from memory but the offline flash didnt work as well for me when stuck in weird bootloops.
Step one-going back to online flash---->
A---
the easiest way i found was to go to C:/windows/system32/drivers/ect/hosts
right click>open with notepad
there should be two lines at the bottom
"127.0.0.1 csmg.lgmobile.com
127.0.0.1 csmgdl.lgmobile.com"
i would cut them out and paste them in a text doc in the same folder for reference later...
but either way you should remove them from the hosts file and save
B----
Make sure your small server is closed! once you minimize it it should go down to your status bar (shttps)
Step two-LGMS---->
make sure you have LG mobile support installed or install it.
open lg mobile support
install needed drivers for your phone
power your phone off/remove the battery
put battery back in
connect it to your computer holding down the volume up button
S/W UPDATE mode should pop up, if it doesn't preform and hardreset and try again til it works (it will)
then in the top right corner there should be a button or two click them both until you see
"restore update" or Update restore or something to that effect
select that
and let it ride man
i got my phone ****ed many times and just had to keep redoing this until it worked. if your bootloader is truely unlocked you can probably go through all that again and get CM10 working, i did but im still working through kinks.....
GOOD LUCK feel free to ask any more Q's about this process if you run into any problems

LG K8 2017 stuck in Fastboot mode

First off, I appreciate any input on this very much.
The phone is an LG K8 2017, or model US215, and this is actually the second time this has happened on a second device. Both times this has occurred, it's been during charging.
The first time, on the first device, the device was off when I took it off the charger, and would not power on until I removed and replaced the battery. Later that day, the device seemed to be lagging, so I rebooted it, and was taken to the fastboot screen. I Googled and Googled, and corresponded with LG before taking the phone back to the retailer and exchanging for another, as I'd only had it a few days.
Now, with the second device, which I've been using for several weeks, there were a couple of times that the phone was off after charging, and the battery had to be removed/replaced to start it. This time, the phone was (maybe for the third time) off when I removed it from the charger. Fearing the same issue, I removed/replaced the battery, and unfortunately, was met with the fastboot screen. LG will repair it under warranty, but I don't have a backup, and can't go weeks without a phone. I've searched high and low, and cannot seem to come up with an answer, or find a situation identical to mine.
I've tried fastboot reboot with ADB, but it requires USB debugging to be enabled on the device, which mine was not, and I'm not able to access it now. The phone was completely stock. Hard-reset does not work, as it always boots back to the fastboot screen. I am, however, still able to access this screen, and download mode. I've tried to include as much info as possible, but am eagerly awaiting responses, so I can answer any questions. Again, thank you to anyone with input!

Thank you for the response! I see the link for the firmware, but I'm not sure what guide you're referring to?
[EDIT] I think I found it. Will update after I follow the guide.
Unfortunately, LG Mobile Support Tool just tells me, "The phone is disconnected from the PC." Even in download mode.
The only time the PC seems to recognize that the device is there is when it's on the fastboot screen, however, LG Mobile Support Tool still gives me the same error.
