Bricked phone after Flashing Custom Rom - LG G5 Questions & Answers

My Lg G5 (Tmobile) keeps on rebooting to recovery mode (TWRP) no matter what rom I flash. I tried using LG Up software but no matter how many times I install the driver phone is not recognized. Firstly I flashed Fulmics ROM then I installed LineageOS (Cyanogenmod) after that phone was working fine for a while till I saw an update and tried updating it to new nightly version. Please help me out if anyone knows how can I fix this issue.

You probably need to put the phone in download mode and then try LG up otherwise try pushing a rom that works through adb

I am sure this method would fix it but I already returned my phone and got new one as I had 1 year warranty. I bought it from T-mobile and I locked the bootloader before turning in the phone so it doesn't look like I was trying anything fishy. Now instead of phone going to twrp each time it goes to boolop saying "device is currupted and won't boot". It won't go to recovery mode no matter what I do and hope I don't get charged from T-mobile saying this and that.
However, I am really grateful to all of you great people who tried their best to help and you sir actually threw me a solution but I was too impatient to wait for it. I know this method will work no matter what as I had been using this tool for my G2 in old days and fixed the worse bricks where I had to openup the whole phone take battery out and stuffs like this. I was looking for this method found everything but LG tool asked me for .dll file which I couldn't find anywhere and decided to give up on it...
Thank you for your help and now I know I am not going to be bricked anymore as I have this method to work with in future issues and am her waiting badly for Xposed to be available for Nougat.

Good to hear that, You are welcome,
And as you mentioned about "device is corrupted and won't boot", that's because you locked bootloader. And as you were using twrp which means modified system partition so phone said that. But you can still go to download mode and use the method to make it live or can try unlocking bootloader to start twrp.

I experienced similar situation. I thought I had to send my phone for repair. As I was able to put the phone to download mode, I used uppercut with downloaded kdz file from LG G5 development thread and restored my phone. I didn't use my phone for four days thinking that I had to take to a phone shop or send to service center. But after careful reading of unbrick tutorials, I brought my phone back to life. Now I can play flashing anything as I am confident that I can easily unbrick my phone.

A few days ago I got my G5 H830 and came with version 6.0.1 h83010i, looking for information on how to install custom rom, I read the post to install the .TOT file to be able to install TWRP and through this the Custom Rom, until there is Everything okay, I did everything right, but then I decided to go back to the Rom stock, on the night of that same day I saw that when I reboot my cell phone it stuck on the LG logo and it had some color pixels damaged (but no screen Damaged, if not because of small brick) then force a restart and continued the same, I did factory reset by stock recovery and then normal start, I went to sleep leaving it in 100% battery, and when I wake up in the morning the cell phone It is off, when I turn it on 5% and I get scared, then I wanted to go back to custom rom to leave those problems behind, but then when I install the TOT again and install the custom ROM it will restart half installed and any rom that installed it would stay Stuck and the LG logo and a bootloop until when it was flash the kdz several times until the cell did not want to ignite more, the pc does not recognize it or anything, I need help with this.

[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.

LG L9 bricked to the limits

I probably just did something, that is supposed to be impossible. I bricked my LG L9...
I had 20f soft with root and tried to unlock bootloader using some method, that is about flashing KDZ files of V10 and V20 roms using offline mode of LG Support Tool.Well it looks like something is not right. After the whole process, the device rebooted aaaand stuck on the second LG logo, I thought it was fine, just need to hard reset but no. Now, when i try to hard reset i get the "dead android"with the red sign, and every rom i'm trying to flash using this offline support tool gets only to 50% and then says, that the device is no longer connected (?????). I tried to get back to stock rom using support tool recovery but same here. 50% and nothing more. Today, i've bought 910k cable, heard that may help but i'm not sure how to use it.
If anyone is able to help, i would be very grateful. And sorry for all spelling mistakes.

[PLEASE HELP] T-Mobile Galaxy S5 Random Reboots, Freezes and Force Closes.

Hello, This is my first Post on XDA so please help me to familiarize myself with rules and procedures and I apologize if I break any in any way.
Okay, So My phone (SM-G900T) is about 5 months old. I bought it in August, Without insurance (Terrible Idea), and now it is having problems. In the amount of time I've had it, I rooted it in mid to late September and used only an app called Xmod for a game. I then started using greenify, solid explorer and eventually used Xposed installer to try a few Xposed modules. Specifically I used, the YouTube adaway, Rich Pandora notification and that's about it. I also later installed Samsung Tools to backup my IMEI and important partitions.
A few days ago my phone randomly rebooted in the middle of a YouTube video so I let it reboot, but it rebooted again, and again, and again. I pulled the battery and turned it back on but the same problem persisted. I couldn't do anything to fix it so I just decided to factory reset the device through the stock recovery. Also, I did not install any custom roms or anything either. The factory reset did nothing. Now when I was in setup, everything force closed, froze and rebooted, repeatedly. So I found the original firmware that my phone came with and flashed it to my phone through Odin because I literally had no hope of what to do anymore. The problem lessened so I didn't install all my apps and overload the device as it would reboot when the RAM would get pretty full or too many things were running simultaneously in the background or foreground. The problem got a little worse so I factory reset one more time and it lessened again but now it came back and factory Resetting isn't lessening the problem. Now it just force closes a bunch of stuff and freezes and reboots into a bootloop midway through initial setup. I am desperate at this point right now and I need help from you guys. I don't have warranty because I rooted and I made the Extremely stupid decision of not getting insurance. So please can anyone help me out? I will be eternally grateful if you can help me turn this $609 brick into a phone again.
I will try to check this thread daily, but I go to school and I may not respond immediately, so please understand.

Do you have SD card installed? If you do try taking it out and leave out or replace with another SdCard. Then flash the original stock firmware as you said you did before through (odin!) Then if that dont work try kias3 and use the emergency firmware recovery tool. Before you do any of this make sure you factory reset through stock recovery if possible.

Have you tried this tool? I had the same issue with my phone and reinstalled firmware and stock recovery through this tool and it stopped. If none of these tips work id say your phone may be borked or have faulty hardware. Take a look here as welll. Hope you can get your phone back to normal.

Okay, so I'm resetting it back to stock firmware through Odin as we speak. And yes, I had an SD card and have already taken it out and left it out and reset but still the problem has persisted, I will definitely try the solution you just mentioned, here I go. And thank you for replying...
Edit:
Hold on, which do you want me to try first? kias3(can you please link it if possible) with emergency firmware recovery tool? OR the Unified Android Toolkit?
Also... I don't exactly know how to use the toolkit, can you verify the steps to take to use the toolkit properly if I should use this solution? I'm sorry but I'm not very advanced at Android development, just intermediately experienced I suppose...

Try kies first that dont work try toolkit. Just Google how to use the toolkit it's pretty self explanatory but I don't think you'll need to use the tool kit anyways. http://www.sammobile.com/kies/

okay, I tried resetting it using Kies3 but the device was not recognized so I had to find a different way because the guide on how to use Kies advised using Odin if Kies didn't recognize your phone. I don't have a code either, So I tried reflashing the stock firmware through Odin and it started up, froze and went into what I presume to be a bootloop as it is stuck on the T-Mobile splash screen with the notification light pulsing continuously. Did I also mention where my phone says Knox warranty void 0x1 there is another statement that says "Counter: 4" or something like that, while I am in download mode, does this have any significance? but yeah, other that Kies and Odin, I'm not sure if the android toolkit will help, because it's basically doing that same thing as I am with Odin, just more automated... Or am I wrong?
but as far as I know, that toolkit is literally the last option I have left, I guess I'll be trying that out tomorrow, with option 10 I believe where it says "10. Download, Extract + Flash Stock Firmware via Odin" but I'm not sure what ADB mode means... I can't really boot up the device so I don't know if that applies
Also, on a side note, how much do you think this will cost if I were to send the phone to Samsung and pay for repairs out of pocket, and do you think they could even repair it at all?
You know what... Do you think if I somehow installed CM12 on the device that the problem would fix itself? Because to me it seems like it's the Samsung software itself that is causing all this trouble along with a few Google apps. Now how would I root it and flash CM12 if it won't boot up fully...
Not sure if this would brick my phone either, let me know if it would if I tried to root through Odin and try to install CM12 through CWM recovery or something
Just throwing ideas, hoping this thread doesn't die before my problem is solved
Also, does geeksquad repair Samsung phones one time for a low fee if you've voided warranty?? If so then this could possibly be my final solution.
Also Never EVER buying a Samsung device again, they just aren't what they used to be back in the day, the other OEMs have caught up and left Samsung and their revenue in the dust...

I disagree with this completely. Very few other handsets can hold a candle to the S5 or the Note 4. I don't know of anybody that has the problems you are describing with their phones without a hardware issue of some type or bad app. The Samsung software runs perfectly on millions of devices without the issues you're having. Therefore it's probably a bad app you've gotten a hold of, or you have a bad phone. CM12 will only introduce more issues and probably won't solve anything.
A stripped down custom rom might be a good bet because you can then start adding your apps back to find out where the issue is, or if it still has the same issues then it almost guarantees that there is some kind of a hardware issue.

Bootloop - LG and TMO screen, will not boot into TWRP using Factory Restore

So, I'm im at a loss here... I haven't done anything to my phone today other than turn on the Webserver at Boot function in Adaway, which I'm guessing is the culprit here... but based on my inability to fix that, which I've fixed Xposed issues before, I'm not confident.
so I'm bootlooping on LG screen primarily, phone was working fine next minute it was off and wouldn't turn on. Took battery out, etc... thought it was the batteries at first, charged both fully, continued troubleshooting. Rebooted a few times it'd boot, show my unlocked Bootloader screen, continue as if going to TMO screen, back to LG screen.
So I tried to boot into TWRP via Factory Reset method. I follow the prompts and then the screen locks, randomly the bootloader unlocked dialogue reappears.
Computer previously recognized device via ADB, now it does not, even with updated drives and ADB/Fastboot. Had the device install itself a few times when plugged in, did not help.
I was able to boot into Fastboot one time, while in there I thought maybe it's an issue with TWRP, so I reflashed TWRP 3.0.1 through fastboot and ran fastboot with the twrp image command... screen locked and nothing happened.
I'm not sure what to do at this point without Fastboot being accessible through computer or regularly through manual method. TWRP is pretty much,... man I don't even know where TWRP is at this point it hasn't made a single appearance in this troubleshooting session.
Any ideas I'm missing?

If you can get fastboot working again try to just boot twrp rather than flashing it
fastboot boot nameofrecovery.img
Other than that try using lgUP to flash rooted MM if you can get pc to recognize phone

hey bud - thank you for responding. I actually by the grace of god, just got my phone to boot into fastboot mode again. It wouldn't even turn on since I wrote this post so I've just been browsing for alternatives. Literally on the LgUp page as we speak thinking that's going to have to be the route I take even if I lose all my data... at least I won't have a brick. I ended up using a method I've been trying all day, it's weird how it's hit or miss on when it works... held volume down and plugged in USB, not sure why it's working randomly even tried other computers, ports, cables... anyway thanks !

I Knew i was going to leave something out, if I flash rooted MM, couldn't that make things worse if I'm on TWRP for LP. I'll read the instructions on the up page, but at first glance I didn't see them talking about specific recoveries like on the eliminator thread..
You can follow toungkick's method and flash the .tot and kdz to get rooted mm, this will include the proper recovery
Choice is yours on the method but this way is smooth and rooted MM is great on this phone
But yeah, data will be wiped,
If you manage to make it into recovery you can try and dirty flash current ROM on top (no wipe) and see if that fixes things first so you don't loose any data

I'm honestly losing my mind over this one, I've gotten into Fastboot several times but never long enough to flash much of anything. LGUP won't recognize device and the method to get it to recognize the device by removing the battery isn't work. So I tried manually flashing images in Fastboot and also tried Nexus Root Toolkit as a last ditch effort.
The further I've gotten is flashing TWRP again, and reflashing a boot image...
Believe it or not I just booted into TWRP, it wasn't easy at all but the phone finally went through following the factory data reset method... I was in there for maybe 7 seconds and then screen went black and phone powered off.
I'm getting to the point where, since it fully booted once, booted into fastboot, booted into TWRP, I'm not convinced this isn't hardware related? But I'm not an expert there.
The only way, literally that I can get it into Fastboot is to take the battery out entirely, hit power a few times to drain it, hold volume down insert cable... the screen comes on with the battery indicator but it flashes a red question mark and I simultaneously throw the battery in while holding down volume... and fastboot boots right up ... I only have a few minutes each time and even though things are successfully clashing (I also erased the cache) nothings working.
I was in TWRP long enought o know that it appears all my data is still in there, was hoping to get to Xposed to delete... maybe I'll look into the xposed uninstall zip and see if that helps but really.... wondering if my batteries got screwed up somehow with these new cables I'm using. never read anything quite like this one
Closing loop here. Phone bricked for sure. Got replacment on warranty. Back up and running rooted MM tho with jun method.

What happened to the original phone?
Phone died on me, and now I'm stuck on the LG logo. Not actually fully booting.

I was never able to get it to boot. Even tried flashing through lgup and it would never make it through.. I took it to tmobile and got it replaced through warranty. Cost 5 bucks. You can manually boot into fastboot or download mode and flash images if your phone will stay on long enough
Im afraid my phone did the same thing. Ive done all of what you mentioned. I guess i have no other choice but to go to T-Mobile and exchange it. You say it only costed you 5 bucks? How is that..? I thought after you void its warranty ... U'd pretty much be stuck wid ****.???

I found this page (https://guidebelajar.blogspot.com/2015/12/guide-to-flash-bricked-bootloop-lg-v10.html?m=1) and am currently in the process of 'refurbishing' via LGUP.
I was able to get into download mode using the following method
"Now turn your LG V10 H900 (AT&T), H901 (T-MOBILE), VS990 (VERIZON) phone off, then click continuously on the up volume and connect your phone to your PC, "

Hard Brick after 20j to 20e revert- Don't do it!

UPDATE: Read this!
TLDR: Don't flash 20j update and try to revert....== HARD BRICK
Long version:
The new 20j update has the Anti-Rollback feature tag set that you can NOT revert back to 20e.......You will HARD BRICK your V10 if you do so. I have...and a few others have.
I was on Eliminater74 20e rom, which is excellent. But he released a P1 .zip for the new 20j update. This contains new bootloader etc. (no P2 which is the actual rom for 20j yet.)
This will boot on 20e, but users (myself included) noticed video issues with YouTube and soon after, others reporting that video recording is broken now.
Naturally, we thought to revert and flash back to the 20e bootloader P1. zip.......and that caused HARD BRICK. Phone gets stuck in Qualcomm Emergency Bootloader mode that is not recoverable.
FIX: Contact " tungkick" http://forum.xda-developers.com/member.php?u=4965298
He helped me un-brick phone. No data was lost! Was quite easy actually. ( I don't see his methods or files he used released here on XDA publicly) (if it is i'm blind.) So don't ask me...contact "" tungkick" .
See post here for instructions: http://forum.xda-developers.com/tmobile-lg-v10/development/debrick-phone-h901-qualcomm-9008-t3440359
I did the same thing, flash tool isnt picking up phone either, I think we are hard bricked at this point...

I flashed V10_H901_V20J_Stock_BootStock_Part1_20160810.zip ...that booted fine. But then I used pheon for a while and noticed YouTube was having issues of videos freezing but audio playin...a few others posted they had the same thing.
So I booted to TWRP and flashed the olde rP1 .zip for the orginal bootstock and hit reboot system and no...Nothing!
Black screen. No vibrate when I try vol down + power. When i try Vol up and connect usb to my computer...It shows "Qualcomm HS-USB QDLoader 9008 (COM8). LG Up says it cant find anything.
Usb device descriptor failed in Device manager when I do vol down and plug in.
I have no idea what do? Help? I have been searching a few forums, but not really sure what is happening.

I was just about to start a new thread asking if I could flash back to previous marshmallow. Anti rollback may be in effect. If you have all the correct drivers installed it sounds to me like a hard brick. Hopefully I'm wrong and someone can help you

And....I assume a hard brick is very bad...not easy to fix? I messed up my G3 once, but at least it would show some sign of life.
I am not at all experienced with adb or fastboot..and how to get all that to work...I have tried, but with no success. Don't suppose there is someone I can send my phone to have it unbricked?
Same predicament here

Oh guys.... I am pretty sure that I've read around here and there that when you get that Qualcomm message you're not recoverable. I surely hope I'm wrong!
Sent from my pretty nifty brand new LG V10
Yea....it sucks. I have literally been up all night trying every method I can to recover from the Qualcomm Emergency Bootloader mode I'm stuck in. There are some LG programing tools that seem to be fake/scam by some user...but those were for the G3 and G4 anyway. Nothing I tried worked.
Just bought the V10 2 months ago used off swappa, already rooted, twrp etc..about $300. Just got the thing all setup the way I wanted it too...sigh. THis is what I get for not being patient and seeing what others experience before flashing something so new.
I was slightly aware of an "Anti-rollback" thing,,,but had no idea it would apply to same and inter-version version of OS. I still don't get why flashing the 20j bootstack on top of the current 20e rom would have caused the video freezing of youtube issue. Standard troubleshooting measures dictated to flash back to the 20e Bootstack to see if the issue went away(I have flashed back and forth bootstack etc on my G3 before with no issues).
Whelp......I guess myself and the other user (SIGMAxB) the 2 confirmed hard bricks served as the community warning........and my very first hard brick and loss of a device in such a fashion. THankfully, I was able to find last night another used V10 on Swappa that is already root and TWRP...for slightly less money that what I paid for my now bricked device. Least I had made an LG backup last week, and all my data is on the External SD card...but still gonna be annoying to have to start over......
Any mad scientist or master flasher who knows how to recover such a bricked device... I would be interested in sending it to them to fix....(I doubt T Mobile will give me a new one, nor wil LG Service the device. It's still under LG warranty, but their site requires u upload a copy of the receipt, and their terms state only covers original owner. So used phone off Swappa.....does not qualify. )
Dropped off my phone at a place called CPR (Cell Phone Repair). Thier location near me is more advanced than most others in that they can do data recovery and software kind of things. They said they may be able to fix phone, but he isn't very sure. Said there will be some techs in tomorrow that are more advanced that may be bale to help. I personally don't have much hope, but worth a shot at this point.
Until then...using my Moto X Pure for now...while I wait for the replacement V10 i bought off Swappa to arrive.
That really bites man.....I'm sorry.
I'm a prepay customer....they have different policies for us vs post paid customers.
I called 611 and got transferred around a bit. But finally got them to process a warranty exchange. I have to ship them the phone and they will send me a new one....hopefully. They didn't mention anything about a charge.
So at least I have that option to pursue should CPR place fail to reflash phone.

I did the same thing. It really sucks because I been doing this for over 5 years and this is my first brick. I guess thats what we get for having faith in a developer that should of known or properly tested this before putting a rom out.

While I agree that things should be tested...or otherwise noted that it has or hasn't been so.... (OP does have Status: Testing posted)
It wasn't the rom, his 20e rom runs great. But the updated P1 20j(bootloader)zip....it was the act of reverting and flashing the previous Bootloader version that caused the Hard Brick.
Until this point, I (and many others here) had not seen anything about the Anti-Rollback feature being an issue while on the same Android OS version (LP or MM builds). Now we know it is.
Additionally, the other posts on Eliminater74, rom forum....are indeed users reporting issues with the 20j zip...(mainly Video recording and YouTube streaming). However, the phone is not bricked.
Unfortunately, it's on us folks who flashed it right after it was released and then tried to revert who got screwed. It is definitely a good idea to wait a few days after something is posted to be sure others, mainly early adopters, don't report issues. If your phone is mission critical and you can not be without it or risk having a issue, then modding is not what you should be doing. Or at the very least, once you do get something flashed and stable.....stick with it (that voice in the back of my head was telling me this when i decided to try the update).
I am not sure as to how Eliminater74, had tested the P1 20j bootstack flashed to his 20e rom....but yes,,,,it does suck that this happened...but I am kicking myself in the head...not the dev. At least mine and the 2 others gave him waring and he was able to post a big red warning on the OP. Though I would suggest he remove the 20j part.....but that is up to him.
Least i had a backup phone to make use of until i can get a new V10...very annoying to have do so...but its something.
PS: I am actually starting to like my Moto X Pure more. Dual front facing speakers really nice. ON stock rom now, but used Bliss or while....that's is very nice and super tweakable. Screen isnt has sharp as the v10....and camera is just super basic. I also miss tap to unlock and the other LG specific features...but stock android is growing on me. The BT toggle has a dropdown to select devices to connect to right there, very convenient.
I'm definitely buying LG phones

left my phone with a place called CPR, Cell Phone Repair. I doubt they will be able to do anything with it. But once i get it back...probably tomorrow if they don't get back to me. I will see about that. Although, I did get t-mobile to approve an exchange, but i have to ship them my phone back first.
Just got a replacement V10 used off of Swappa. It already has Eliminator rom on it, though not sure what build. Attempting to restore my backup file to it.

I assume there is a reason you haven't released this method and files publicly on XDA right?
I also am assuming you don't want me or others spreading this to others.
If i am wrong, please let me know.
