LG G4 Bootloop - my experience - G4 Q&A, Help & Troubleshooting

[deleted by dentralp]

so first bootloop appeared right after updated to MM ?
How did you updated? did you flash only MM bootloader + modem + custom rom in twrp or official MM ?
did you have any provider bloatware installed?

I guess it's a different problem with your phone. I read that almost all defective units were 505 and sold on US providers. Maybe your hw it's ok though and that's why you didn't get a replacement.
But keep trying to reflash it, maybe try a different battery, try lgbridge
Just a thought.
Goodluck

For everyone having the bootloop issue, I saw this in another thread:
...
Using DL mode (device off -> press and hold volume up while(!) connecting to PC) and LGUP you should be able to push any KDZ on your device and get out of the boot loop.
...
I don't have the bootloop problem so I can't test it but it's worth trying.

I think LG refused the warranty because the unlocked bootloader not the rooted software.

Thread closed.

If you are here looking for a fix I don't have one, just wanted to put my experience front and centre. This is my full experience starting 12/12/15 through to 14/01/16 taken from this thread;
http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734
Last Update: 14/01/2015 - LG refused warranty repair due to the device being rooted
Solution (Clean Software): RMA to LG or place of purchase
Solution (Modified Software): Find some paper to weigh down (UK). Give a warranty repair a try, you may get lucky
Solution (General): Don't buy LG's Hardware - quality control is questionable at best
Although some people have reported getting some functionality back, no such luck for myself and majority of others.
What I didn't try;
Click the show content button to see what was tried and updates on the RMA. Pre-warning, this is my journey starting 12th December and is all condensed to 1 post.
Attempted Fixes:
1) Tried using LG bridge
2) Flashtool 2014 - Europe OPEN H81510D.kdz
3) LGUP
4) Longshot
5) LGUP
Updates
I am Hopeful that everything else will be smooth. +rep to @nashant for the recommendation re LG customer services.

Volume buttons not working / Need to go back to stock

Hello,
I've noticed that my volume buttons have pretty much stopped working. I don't think it's ROM related, I'm on tmcode's AOKP rc2 ROM and tried going back to CM10 stable and the problem was still there.
Sometimes they'll work randomly, but they're pretty much a write off it seems. My phone is under a year old purchased from Bell.
I've unlocked, rooted the phone, flashed CWM and have flashed numerous ROMS.
I'd like to try and see if they'll give me a replacement, or fix it or whatever before I get a new phone, which most certainly won't be an LG phone, too bad about the Nexus 4...
What's the easiest way to bring the phone back to a stock state? Do you think if I just flash Bell's ICS ROM it'll be enough?
Thanks
you haven't given us much info... my p930 works fine (edit spelling) on cm10 stable... if yours still aren't working i'm guessing one of two things.
1. maybe your rom flashing procedure is lacking... ? are you doing proper data wipes before flashing new roms?
2. did you jolt your phone? if you smashed your phone from the side the volume buttons are on its easily the contacts could have been damaged.
either way i think if your flash count is that high your warranty is probably useless, unless there is some way to hide all those custom roms you flashed but there isn't as far as i know.
you can only hope your problem can be fixed by doing a proper wipe... just another thought... have you tried restoring a backup from CWM from before you experienced the problem? this should confirm weather it is a hardware or software issue.

What do you mean "flash count is that high?" I mean, if they really care about that, just update through the LG updater tool and they would never know you've been flashing all sorts of custom ROMs.. Which, if you think it MIGHT be a software problem, that might not hurt anyway; but I doubt it's software related..

I see what you're talking about now. From what I can tell, it's on Samsung devices; I can't find any other references to it on any other brand... not saying that it isn't on anything else, but Samsung appears to not like people having full control of their device.
I don't think it's a software issue, I'm pretty sure it's hardware.
I know to do a full wipe when flashing between different ROMs.
My phones been dropped a couple times, nothing drastic though, that could have done it maybe. I've got a TPU (sp?) case on the phone.
What is the easiest way to bring the phone back to a stock state? LG GB/ICS ROM, un-rooted?
Thanks again

You can try running the official LG update tool; I'm not sure if that will work without doing anything else... I KNOW it works if you flash v18f and then update with the official software. Basically, run through steps 1-5 of this guide: http://forum.xda-developers.com/showthread.php?t=2044645 and instead of doing anything after all that, just start the official update software and update to Official ICS.
" just start the official update software and update to Official ICS."
I'm using the Bell phone unlocked on Rogers, will I still be able to update to the official ICS ROM?
RealyPssd said:

From within the phone it self? Or is it an application I download and run from my PC?

B2CAppsetup.exe is the app you'll need.
pretty sure by official lg update software he's talking about the tool you run on your pc that autoupdates your phone.
http://www.lg.com/ca_en/support/mobile-support
is where you would find the tool, i'm not 100% positive on this more like 99% if you want confirmation you should wait for him to verify, but i know this is the official lg update tool.
---------- Post added at 06:37 PM ---------- Previous post was at 06:35 PM ----------
if you blocked the lg site from your hosts file like the (*edit* un) bricking guide tells you to, you'll have to remove that line from your hosts file (127.0.0.1 csmg.lgmobile.com) and flushdns in order to communicate with the lg servers again. just in case you run into this, i'll try to have your answer posted before you can ask the question
to flush dns open the run prompt, type cmd, hit enter, type ipconfig /flushdns
you should get a success message this has refreshed your dns and you should be able to communicate with csmg.lgmobile.com again.
---------- Post added at 06:42 PM ---------- Previous post was at 06:37 PM ----------
as per your 2nd question, i'm pretty sure you'll end up with A T&T but im not positive. however the at&t software will work if you enter your carriers APN settings, if you didn't write them down you can get them with a simple google search, go into mobile network settings on your phone select apn, then push the menu button and push new, then enter all your apn settings and your data should connect in a jiffy.

Yeah, the official update tool. That's the one I'm talking about; both links end up going to the same program - B2CAppSetup.exe
Good point on the hosts file, that's pretty important.
thank you just trying to him this guy get his phone going
Alright, once I find a cheapo phone to use while my Nitro HD / Optimus LTE is being repaired, I'll give this a go.
I just want to bring it back to stock state to remove root so they won't deny my warranty.
I remembered after I posted about the "B2CAppSetup.exe " program on LG's site.
My hosts file is untoched, I'm on a new install of Windows 8, I un-bricked a few months ago.
Thanks again for all the help.
I can't really, reliably, enter recovery any more...
I might try flashing the v20f Bell ROM via ROM manager and then try unrooting with super one click.
I do still have the first CWM backup I made of the stock GB ROM as well that I could restore maybe in ROM manager.
Sent from my LG-P930 using xda app-developers app
So I flashed the original GB CWM / Nandroid backup I had made, then I tried un-rooting with SuperOneClick, but for some reason it wouldn't work.
So I used the LG software and updated to the official ICS release, Bell version, and the now the phone is un-rooted.
Time to send it off to hopefully get fixed.. what are the chances that I'll get my actual handset back? I've unlocked it, I'm betting I don't get mine back, but a locked one...
Thanks again for all the help
first of all you dont want yours back, the volume button issue is probably hardware, unless you flashed the wrong rom or a corrupted wrong or something. secondly if you updated to stock ics, your phone is already has a relocked bootloader, you should be so lucky as to get a brand new phone that you can unbrick in an hour...
*edit* unless there is some new security they are putting on the new ones but i haven't heard of such, it has always seemed to me they only implement security to the point where it will stop an unknowledgeable person from breaking the phone. the amount of software "leaks" suggest to me they don't really care if people that know what they are doing mod the phones. having said that they still won't replace a phone they know has been modded, for valid reasons, they shouldn't be responsible for things they didn't do to the phone.
So I got my handset back and the volume buttons have been fixed.
To get root and CWM recovery back is it easiest to just follow an unbrick guide?

Recover data from bootlooping phone

I don't know if this was already posted, I hope not. So, a dude on reddit has managed to download some files from the LG site and this one seems that it's about the recovery of data on a bootlooping phone. Here's the post:
Every once in a while I used to peruse LG's service bulletin site (whose URL I cannot recall, dammit) just to perv about on all the fun info, and apparently back in November I downloaded a file titled G4.ZIP, which seems to be pertinent to recovering data from bootlooping phones, or as they refer to it in the guide, the "Infinite loop Auto power off"(ILAPO) issue:
From the Powerpoint file:
Sometimes G4 series phone happens “Infinite loop Auto power off” issue.
if phone’s symptom is “Infinite loop Auto power off”, you should Change a Main board.
if customer wants to Data Back-up, you should use this Recovery tool.
Please Data Back-up proceed after Recovery complete.
This Phone (Recovery was completed) is abnormal Main Board.
Please don't reuse the Main Board.
Inside the package is TOT files for several international G4 models, each TOT containing aboot images. In the opening notes it specifies it's for 'Global /All (Except USA, Canada, Puertorico)'. Also inside is install packages for LGUP and G4 flash dlls.
So are they saying that disabling the BIG cores will allow the phone to boot? Or that by disabling the BIG cores it allows data recovery from another avenue? Why should disabling the BIG cores matter, is that where the manufacturing defect lives? Could BIG core sacrifice enable a G4 with the ILAPO issue to continue to function without mainboard replacement?
Just found this fascinating and thought I'd share.

Here's the file: G4.zip, and here's the original post, courtesy of /u/cutol
So, if anyone could look into it, that would be great. I'm pretty sure there are people who would love to get their data off the phone.
It works :good:
I saw this as well on Reddit. I too was waiting for someone to report.
Now the question is can we continue to use the phone with the BIG cores disabled?
I would imagine it to be a tad slower but nothing major for regular day to day usage
Is there a fix like this for the US VS986?
Thanks!

I keep using it with core disabled for 2 weeks.
It's pretty slow but if you don't run too much apps it's ok.
Will this work if the LG G4 has 6.0 instead of 5.1
Has anyone gotten this to work with a US variant? I don't care if any of the radios work; I just want to boot it long enough to get some backups and write them to the SD card. (I'm luckily getting a warranty replacement from Sprint).

Problem with upgrading to 6.0

Hi guys
Recently i bought my girlfriend LG G4. Now I think it's from Singapore, and I totally have no idea, how to update it. I have 5.1 now, and of course I wanna 6.0. Using automatic option from smartphone still showing "up to date". LG bridge is finding some firmware, but after downloading, at 1% i got error. LG UP always saying, that's bad kdz file ( I download 4-5 of them). When i'm trying to check version by IMEI on devtester, I get nothing. I have no clue what could i do next .

Go into Settings > About Phone > Software Version - at the bottom of the tab click on 'Software Version'. It should give you a version with 10(?) in it (last few numbers in the string). Find one with the same string with 20(?) for the same carrier. Use LGUP-NEW (https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803) and click upgrade to set the 20(?) kdz file you found, then proceed to upgrade it.
Good Luck.

By carrier, I mean the wireless company that provides the phone/texting services to your phone ... if the phone wasn't bought from the original services company.
If it was, the other option might be to try a factory data reset to see if it allows the update to 6.0 to come through automatically - you will have to back all your data first, otherwise you will lose it.

Tell him to flash the H815 European firmware... it will not do any damage because the OS has the same signature across all variants, so the bootloader will accept.

I know that i can't root phone with 6.0 but first of all - it's for my girlfriend and i think, that she don't care. Second - with quite long history with android, i never rooted any of them. I never saw a reason and also i'm bit scared when we're talking about more complicated actions . Anyway, thanks for advice. We will in next 5 hours if i finally get 6.0 on this phone

You're lucky you have the European version.. you have no idea how much hassle I went through to get that version...
So anyways, since your bootloader is unlockable, I recommend you unlock it first, prior to flashing anything mentioned by sdembiske.
I recommend you also root the phone and install TWRP, just incase something goes wrong while flashing, you can easily recover the phone, and not have it completely destroyed.
Once you have rooted, unlocked bootloader, and installed TWRP, you can safely do literally anything on the phone
Flashing the rom can easily make your 700USD device worth 0, within seconds... so Please .... take the precautions.... and install TWRP
Cheers

LG Flash Tool has many more bricking issues than LGUP-NEW. If you ever decide you want to roll-back to 5.1, LGUP-NEW will throw up a roll-back version error if one is present - LG Flash Tool will not and will result in a bricked phone. Overall, your best and safest bet is to use LGUP-NEW.
One note: There are fraudulent sellers of supposed H815's out there and as you bought yours through auction there are no guarantees. To be on the safe side I would check with the seller to see if you can ascertain if he was the original owner and ask where the phone was purchased (what country) and who the original carrier was.

https://forum.xda-developers.com/g4/help/korean-g4-f500k-t3150548
Before you do anything, be 100% sure what variant you have. To do so, please enter the following codes in the phone's dial pad:
*#546368#*815#
*#546368#*500#
If the first one works, you have the H815, if the second one works, you have the F500K ...
Report your findings,,,

Power down the phone, pull off the back cover and take out the battery. There should be a white tag under it - make a note of all the letters and numbers there. Provided the tag hasn't been tampered with, it should provide a good idea of what model you have and help narrow down your search for a kdz/tot that will work. I would still check with the seller of the phone and seek some verification. If the auction site is reputable, you may have some recourse if the phone is not as it was sold as.

The physical label is easier to tamper with, than the actual software. Just go by my suggestion.. the MMI codes.

The member providing you with the codes to access the hidden menu seems to have forgotten that not all codes work for the same models (as he himself found out when he tried once before) - there are carrier firmware variations with locks imposed on being able to access some. IMEI's can be changed by 'snakeheads, pimps' ... and fraudulent sellers.
Frankly, you are lucky you haven't bricked your phone completely by flashing different model/carrier variants and if you had used the LG Flash Tool to install the H815 kdz variant he recommended, you most likely would have. The same member has, for a fact, provided misleading, misinformed and potentially very harmful advice to other less informed members.

What do you mean "if you had used the LG Flash Tool to install the H815 kdz variant he recommended, YOU MOST LIKELY WOULD HAVE" ??
How do you know for sure?? Have you tried it??? NO you havn't tried it, so you have no right to say "it would most likely brick it".

Hey buddy, let's check whether your bootloader is unlockable before you do anything. Please download ADB (Android Debug Bridge)
Before we do anything, make sure "Enable OEM Unlock" and "USB Debugging" options are enabled.
Once you install ADB, open Command Prompt (Press Windows Key + R , then type 'cmd' and press Enter key)
Issue the following commands:
Code:
cd C:\adb
Code:
adb start-server
Code:
adb devices
At this point, your device should show up under the list of devices. If it doesn't issue the following commands to restart the ADB server:
Code:
adb kill-server
Code:
adb start-server
Then, check again whether the device is being detected
Code:
adb devices
If the device is not showing, please check whether drivers are properly installed
If the device is being shown, you can proceed to the following command:
Code:
adb reboot-bootloader
If the device just boots back to Android, then the bootloader is locked, and you could have any device aside from the H811 or H815 European version
If it boots into the bootloader, then you have either the H811 or the H815 European version, and you should be able to easily root, install TWRP and flash any variants kdz file.
Now, if you have got this far without booting back to Android, time to unlock bootloader:
Code:
fastboot oem unlock
Once complete, issue:
Code:
fastboot getvar unlock
If you get the message "Unlock: Yes", then you have successfully unlocked bootloader.
Hope this helps

let him try the codes first ok...
If it doesn't work, then you complain... Otherwise you be quiet
You have no right to talk on his behalf and tell what works and what doesnt ok... let him try and see

[CLOSED][ANY BL locked G4]need testers [follow the new thread!]

First of all: Do not continue if you don't know what a hard brick is!!!
so well its that simple: Either my method will work or fail.
Please follow the story here now:
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
Previously this was the OP:
if not: this could result in a completely unusable device (soft or even hard bricks are possible)
If it works: you could unlock your phone in fastboot with a simple command - no unlock key is required (but even when the method WORKS its possible that this produces other issues. we can not know all impacts yet)
So AGAIN
The whole process is dangerous but the chance to get an unlocked phone would be worth it - maybe. It depends on you.
I can't test it atm by myself because my device is on its way to LG (due to another issue)..
My method does not modify something within the bootloader like others tried already - because this would definitively break the boot chain.
I will not release any details to the public until there is anything proofed or verified. The whole process is very risky and as said: I have currently no device to test it.
The only thing which is proofed is the theory. It should work as long as nothing unpredictable happens: As long as we do not own the complete sources of all parts of the boot chain there is still a risk.
Keeping the details under the hood is not to make things mysterious. It's just for safety reasons until I can proof anything.
If you still ask for details here or by PM they will not be answered.
If you not able to join an IRC channel you better leave it directly.
I'm not 24/7 online but usually from Mo-Fr for sure so it is important to wait for answers while in the IRC because depending on your timezone this can take some hours (hey I have to sleep somewhen!)
Once I have my device back from LG I can test the method by myself on a H815 EUR version. It doesn't matters that this can be officially unlocked though. The risks are the same.
So if you're too scared for the moment just wait about 2 weeks or so and then I can tell if it worked on my device at least.
.... and if you do not want to wait: Follow me into the IRC for instructions
If you never were in touch with IRC before here are some client examples for you:
PC (HexChat and Pidgin are only 2 of them! This list is not complete!)
Android (Yaaic, AndChat, HoloIRC, AndroIRC are only a few of them! This list is not complete!)
The IRC channel is: #Carbon-user
The IRC server network is: freenode
Once you're connected with the IRC network I need this from you:
your phone model
the currently installed EXACT firmware (link to the used KDZ would be most helpful. If you have none check the phone details and e.g. make screenshots)

It happened to mine 818p too, you need to disasseble it and short two pins on the motherboard while starting it. (They are in the upper left corner on the MB.) This page (forum.gsmhosting.com/vbb/f779/unbrick-lg-g4-brick-hs-usb-qdloader-9008-without-box-2211744/) has the entire process explained but I was unable to sucessfully use the QFIL app, it didnt recover anything, at least the phone was seen on PC as the 9008 serial port. I hope it helps
P.S: Sorry for my bad english.
i hope you get it going man. so lots of users can enjoy this device like it should be.. youll be saving LG G4.. am glad that what i mentioned you got your brain thinking and finding ways i beleive this all was what i mention on fish. good luck to all of you.:fingers-crossed:

Ive done got a g5.no root and no twrp. Yea. Just the way i like it. I know i know. If i wanted root i shoulda bought an unlockable model. But i take what i can get cheap.

Qcom 9008 mode? It could be fixed afaik.. You can also try the sdcard boot method for this kind of brick. you should try that first in any case..
I'm not sure if my method will work in that kind of brick mode you are in but if you nevertheless want to test you need Linux / best is using FWUL because it has everything needed inside.
Once ready went to IRC on Mo-Fr and stay until Im there.

it depends. When it stays in download mode without looping.. yes - maybe!
I need access to to the partitions which may work even in download mode via a special shell but it may requires MM and will not work for LL firmware (strange right? normally one would expect the other way around..).
That has to be tested though. On my device (locked H815) I had access but that may differ from other models.
Having root access makes things so much more easier
Testing if it would be possible on a bootlooping device would be simple:
You best use FWUL (recommended because here is all installed and working) or any other Linux with the LGLaf shell.
You would then connect while in download mode and you will have a shell like in adb.
I can guide you but again IRC is the best way to go here..
I'm searching since several days for such looping and even otherwise broken/defect devices but they all want to have a plenty of money for it (80-150 €!!)

Yes, QCOM 9008 mode. I can't flash the H815 image and make my G4 H815 again so, the only way to booting, it's flashing the LS991 image (and with Fastboot; I flashing every partition one by one).
I have Linux Mint whit adb/fastboot drivers, It's enough?

Hmm I can't help you unbricking. I just know that there are ways to do so. You need the correct drivers etc.. But well if you tried all this already we can try
Any Linux is ok as long as you can handle it
Havin TeamViewer installed may help too...
Well so if you like go to IRC Monday to Friday and we will see

Yes. today I have bad and good news.
First of all I had 1 single tester who was brave enough going the first approach I had. Unfortunately my first idea failed.
JL if you see this come back I said I can unbrick your device!!!
Ok so the good news are: I'm able to give you a near unlocked experience with all the things you love like installing custom kernel, recovery and ROM. Without actually unlocking!!! It's all tested on a h815 device which was never unlocked !
Near unlocked means it will behave like an unlocked device without actually unlocking the bootloader. Or to say it in other words: The boot chain verification is ignored.
The bad news: the process is not cleaned out yet but it requires one thing for sure: it will convert your whole device bootloader stack. The basic idea is to replace the whole bootloader stack with a modified one which allows all the mentioned things.
That way is very risky and I HARD bricked my device over 30 times until getting to the finally working result.
It also means that once your device is converted there is no way back atm. Flashing an original kdz will BRICK your device in 9008 mode! Not that bad because you can recover at any time but that's one thing you have to have in mind. It may never be a h811, h812..... whatever again. Until we find a corresponding and working bootloader replacement which may never happen. So no LG up or LG flash tools anymore! Instead you will have the qfil tool.
Again I know no way back to original state so warranty will be very very likely refused once you do this. Ok there is a way to blank out all partitions just for the case you need to send it really back. This should delete then most traces of this hack but no guarantees.
Besides this I don't know if there are any issues in functionality after doing all this. I havent made any tests for this yet. That includes phone calls, WiFi etc. I just checked booting ROM, booting TWRP, flashing supersu, getting root.
I will upload a video asap to show you the current result.
I need to test things further and of course I need testers with other devices. Again that process is risky and even if it worked for me it may not work for you (very unlikely but who knows). Manually forcing the 9008 is very easy and it may be required to do so. This may requires opening the device (I think it will work even without but I need testers.. ) so if you want to test... See you in the IRC.
If all this is working and verified by others I will provide the whole story ofc!
....can't believe that all these above took me 5 days in full time of work. And for what? I mean I do not need it because I can unlock my device OFFICIALLY..
BUT it was all for educational learning. I learned really a LOT of android and qcom during all these hours ...
Ok but Now I need some couple of hours of sleep
See u on the other site..

[SOLVED] PLEASE HELP - HardBricked my OnePlus 5T

Dear Community,
I just searched the past 2 days for a solution but I've not been lucky
Therefore I'd like to ask for help in this forum and hope there is some additional hint or hack I could try...:
So here's the situation:
OnePlus 5T (8/128) with a non booting or not "useful" OS (see last point what I've tried)
No TWRP or CWM
Stock Recovery present
Bootloader Locked
Allow Bootloader to be unlocked = FALSE
What I've already tried yet:
Flashing TWRP --> Not possible Bootloader Locked
Flashing regarding any other kinds like "update" or "flash all" as provided with TOOL_ALL_IN_ONE
ADB Sideload any available ROMS (Original "full" OP5T / FreedomOS / Omni8) --> ADB stops at 47% in Stock Recovery regardless of size of the ZIP file
Tried different versions of ADB (32 & 64 Bit / older & new / also with the LargeAddressAware approach / and on multiple PC's) --> Always same error (47%)
Stumbled upon the possibility to EmergencyDownload a factory flash due to Qualcomm chipset using the MSM-Download-Tool --> Only OnePlus 5 ROM available (no "T")
Mentioned EDL procedure works and OS is booting BUT neither Touchscreen nor USB OTG (for external mouse support) is working --> So I can't navigate and allow Bootloader to be unlocked again
Unfortunately I'm now stuck and have no more idea how to unbrick my phone again
What would help:
Any source to MSM-Download-Tool packed with a correct ROM for the OnePlus 5T
A Workaround to just flash TWRP via MSM-Download-Tool or Qualcomm's QFIL application in EDL mode
Some "hack" to bypass the locked Bootloader situation
Every appreciated Input you might have that I'm currently not aware of...
So PLEASE let me know of any approach that I could try or if you might have found a link or something else to a solution that might help me out of this disaster...
Many thanks in advance!
Tryouts due to your feedback:
@dreinulldrei - "fastboot boot recovery.img" tried with the original 5T Recovery.img also with blu_spark TWRP --> no luck...
SOLVED SOLUTION:
As the EDL factory flash ROM is currently not (or will never officially be) available public getting in contact with the OnePlus support team is required.
They have such a recovery tool (MSM-Download-Tool) with an appropriate ROM and are able to flash the device during a remote support session conducted via chat.
So by starting a chat on the OnePlus Support page and describing your situation will lead to scheduled time slot where a Level-2 technician will do all required steps remotely.
(All files are password protected and the technician ensures they are deleted at the end of the session so I'm unfortunately not able to provide the sources for DIY purposes...)
Following. I would think there would be some way to flash some sort of signed image via fastboot...
U flashed a 5 os to it, using the msmtool try to extract those files from 5t os, I will do it when I get home and so u can try it, i can't guarantee anything though, would u like me to do that for u

Thanks for your input - I'm really not aware of how to generate such *.ops ROM files as this is what the MSM Tool expects...
But if there is a way and you are able to extract and produce a MSM flashable file I would be very happy to try!
I would recommend trying to boot a OP5T recovery, you might have flashed some OP5 rom including OP5 recovery. Just go into fastboot (power on with volume up pressed down), then via cmd:
fastboot boot recovery.img
Since OP does not offer the recovery to be downloaded, it will need to be downloaded from a working device. Lacking the cable right where I am, but I am sure someone else can help out.

Ohhh good point - I also think there is the "wrong" recovery (from 5) currently on my phone (because also there the touchscreen behaves unexpectedly...)
But unfortunately with your command I get the "Your device is corrupted. It can't be trusted and will not boot" message.
Tried this with the original 5T Recovery.img I managed to obtain and also with the blu_spark TWRP - no luck...
Edit: Ignore, misread previous post.
U may have to make a call to oneplus so they can restore for u
Submit a ticket to One Plus
You are going to have to submit a ticket, they will arrange a time to help you by unbricking the phone remotely.
I just had to do this myself this week, and it got done today.
I do have the 5t unbricking files but I cannot access the archive because it's password protected.
One important this you didn't mention is how this happened.
OnePlus may be able to help with this one, but all root guides explicitly include the phrase "at your own risk."

Thanks for all your advice - so I will arrange a support chat/ticket as soon as possible and inform about the result in this thread.
Didn't thought that OnePlus Support Team would even care about such bricks (no warranty / own risk / "playing" with root / etc...)
But as indeed they seem to help like @WMerkens experienced I would be very happy to have a working device again

don't know why you would think that OP wouldn't help...they have said from day one that unlocking/rooting does not void your warranty. Heck they encourage it. I assume you are the same person on the OP forum w/ this problem. Hopefully after you get this resolved you will have learned to NEVER EVER RELOCK your phone unless you do the whole factory image qualcomm recovery tool bit. and experienced OP folks on this forum know any claims of a "hardbricked" OP phone is ALWAYS not true.
Yeah oneplus used to be good about and does a remote session to restore, this was back in the one plus one days though, but I think they still do it

You are going to have to submit a ticket, they will arrange a time to help you by unbricking the phone remotely.
I just had to do this myself this week, and it got done today.
I do have the 5t unbricking files but I cannot access the archive because it's password protected.

Awwww I wish we could get them, do they use the msmtool too?
How I bricked a 5t
I got the phone and I had installed twrp, that went fine. I was looking at magick systemless rooter when the phone then kicked in with a OTA update, I chose to ignore it the first time. It occurred again a few minutes and in my haste I let it do it's job but it did not complete correctly. I rebooted and the phone complained about corruption to the OS, I got in again but made the dumb mistake of re enabling the OEM lock and because I thought that might be causing the problem. I rebooted again but now I could not boot any more into the OS, it complained I was corrupted and go to google to see what to do.
So I was left with a bricked phone.
I could do bootloader but not recovery and I could not unlock the bootloader.
I could not get in via adb usb debug, So after much research I download the OnePlus 5 unbricking pack and learned a whole lot about qualicom and EDL mode, plus I learned a lot about the QFIL tools and restoring a phone. I did the 5 unbrick but my screen ended up upside down but the touch was right side up, which resulted in a very hard to use phone.
I tried the QFIL method but I was missing a mdb file to be able to talk to the phone.
So I gave up submitted a ticket and after much bad co-ordination on their part got a level 2 tech to debrick the phone remotely.
They do a reverse VPN and connect to your computer, they tell you to have 2 files archive ready in a folder on your desktop (they supply the links). They install the EDL driver and unpack the debrick archive. The archives are password protected, they run the tool and restore the phone
back to factory.
They erase the unpacked archives after they are done.

Oh yes I've learned my lesson on this :angel: --> Never ever set OEM to be unlocked to NO again
Obviously I do not exactly know what wrong procedure made me stuck in this situation but I just wanted to revert every single step back one by one to see which element brings me back to a valid SafetyNet situation...
I've been with the OnePlus "family" since the OP1 but never needed any direct support from the vendor - so every time there's a first time and so for me now...
Thus I really didn't know OP staff is actively doing remote support for their devices - but thumbs up for that! :good:
(BTW: I'm not the guy from the OP forum)

Yes basically it's the same archive as the 5 unbrick pack but it's for 5t, OnePlus 5T OxygenOS 4.7.2-171116.zip is the archive and you can look in it and you see the ops file is for dumpling not cheesburger, which is the code name for 5t. I saw the MsmDownloadTool is 4.0.8

I just had a chat with them before and got mailed a link to the MSMTool incl. ROM for the OP5T (dumpling)
But unfortunatley support files from OnePlus are password protected Nevertheless here the original vendor link:
https://onepluscn-my.sharepoint.com/personal/sheva_liu_oneplus_net/_layouts/15/guestaccess.aspx?docid=0fde9596c72744b4fb9c073ca5d87edbe&authkey=AQPXKRi7pdIzZX-5WH_pwWg&e=1030aa0046da4d1aa9189020027d9c93
So I have to wait for my remote support schedule on Saturday to have the L2 technician entering the password and do the rest.
Would be able to do this myself but OnePlus obviously wants to protect their sources what I have to accept, respect and be patient for...
So, never turn off the OEM Unlocking?
