Possible to flash stock firmware from download mode w/ locked bootloader? - LG Q6 Questions & Answers

Since this phone's bootloader can't be unlocked is it still possible to flash the stock firmware from download mode? (It can be accessed by powering off then hold VolUp then insert micro USB to computer with a cable that can read and write data eg. The stock one that came with the phone). OEM unlock is enabled. Also, would it be possible to flash custom firmware through download mode?

yeah. That's what download mode is for. Even if OEM unlock is enabled it's still possible

So you're saying that we can install TWRP and other stuff that are available in Download mode?

F*&# FRP!!!

So, my Note 5 somehow got reset with OEM unlock OFF. Also, I was running a modified stock rom at the time. Now my note 5 is a really expensive paper weight unless someone here can tell me why odin won't recognize my phone in download mode anymore. How can i flash a stock rom back to the device if it's not recognized? Also in recovery i get these messages:
1. Update from ADB is disabled
2. Update from External Storage is disabled
3. Apply_Cache is depricated
If I reboot to bootloader i get the charging symbol with:
Kernal ins not seandroid
Custom Binary blocked by frp lock
can someone throw some ideas out there about what I should do?:angel:

reflash the stock rom only with odin! No recovery, no root! Then reflash the rest! Do not try to flash with recovery! Search threads for your note 5 version of firmware. And from now on make sure you keep oem on!

Kenny,
The new stock firmware is available here: https://www.androidfilehost.com/?fid=24588232905721433
Unzip it, ODIN flash it.
FRP is automatically activated when you add a Google Account now. Remove the Google account before factory reset, rooting and installing a custom ROM.
PS: I learned the hard way too.

Odin won't recognize my phone at all. My computer sees it as "Unknown USB Device (Device Descriptor Request Failed)." how do I fix this?

I don't recall. Biggest reason I pointed you here is that a proper driver is also included. I think recovery mode though.

FRP Locked - Stock ROM Corrupt - TWRP Backup Corrupt

[FRD_L09]
Ok, here's the deal.
I recently got myself an unofficial version of TWRP.
Installed it, fine. I then downloaded SuperSu .zip and flashed it.
Tried booting my phone; nothing. OEM was unlocked, and i already made
a twrp backup, before making any changes. I am now stuck with a phone
that wont boot up (nothing happens upon boot), and FRP being locked in bootloader.
I realised some ROMs require a custom version of TWRP, which i cannot flash as FRP is locked
in boot loader, and i dont have access to "USB Debugging" since it wont boot. I tried installing
several different ROMs, including LineAge, CM14 and some others. No luck.
I also went to the manufacturer website (Huawei) to see if they would help me with this issue; no luck. Please help me restore
my device to its original state. Thanks a lot.

It shows up in fastboot, but FRP is locked. I guess FRP is usb debugging, since i cant make any changes.

Cant get into recovery mode with buttons

Hey, I changed my passcode and cant remember it. So I was gonna factory reset it. But the button combinations dont work... Have they disabled it?USB and Oen is not disabled ether. So I cant use odin or adb to flash a new rom or use adb to boot into recovery mode. Been searching for many houres now and I cant find anything except Dr. Fone that works but I dont know if its lfit or not. They want 50$ plus for it. So I am hoping there is a way around this.
so you can't go into download mode? i think you can go into download mode even if OEM is not disabled so you should be able to use odin
Fastboot problem
I am with pie ROM and I want to go to fastboot mode but I can't.Under developer options the
USB debuging is ON but when I try to put OEM unlocking ON I got the message that if I do that
the next time the phone starts,will reset to it's factory defaults settings and will erase all data.so I can't put ON the option OEM unlocking.
thanks

to use odin
download odin from here: https://dl2018.sammobile.com/Odin3-v3.13.3.zip
1 - turn off your phone completely
2 - press volume + and volume - at the same time (while the phone is off)
3- connect to pc (while pressing both buttons)
this should send the phone into download mode it will ask you to press volume + to confirm and only them will be recognized by odin
from there i suggest you look at a tutorial online if you don¡t know how to flash a rom

Thank you! I got into bootloader I found this site https://albviral.com/bypass-remove-...-galaxy-a7-2018-sm-a750f-frp-sm-a750g-ds-frp/
Just a bit worried about not getting into recovery mode and do a wipe/factory reset... If i cant get into recovery mode will flashing the Firmware stock 8.0 for A750FN make the phone fine again? Or do i have to have OEM off to flash it?

i assume flashing a rom should fix it, if you a pie rom you will have to flash a pie rom, if you have oreo you can install oreo or pie, to download the rom just use SamFirm

Have you ever tried the combination file rom for samsung? https://albviral.com/bypass-remove-...-galaxy-a7-2018-sm-a750f-frp-sm-a750g-ds-frp/
I have flashed it and i get into system and when i click build number nothing happens so i cant get developer mode so i can turn off oem... this is making me crazy so close ....
Now i have managed to get usb debug on. I find my device the boot recovery mode command it reboots but just continue into combination fil rom? Is recovery mode disabled on this phone can they do that?

Help! Pixel 2 dead screen unrooted, ADB not enabled. need to access data

my pixel two screen died.. google backup restore joke service failed to restore sms or app setting to new phone. i need to grab that data from the old phone but cant see or use the screen, phone is not rooted and adb debugging not enabled. and i am not much more than a novice ahhhhhh!
The same happened to me. Try using vysor in pc. It shows your Mobile screen on pc. It worked for me. You dont need to install vysor n your mobile. Pc verion will auto install it on your device.

thanks for the help but im not sure if I had twrp after all . no matter what i can't get past the adb device "unauthorized" state. turns out the pixel2 is unique in not supporting usb-c to hdmi - thanks Google. i tried unified toolkit and vysor. next thing i might try is a hammer and send the pulverized phone back to Google.

help nedeed cant do anything

bootloader locked usb debugging off cant make command through adb sorry for bad English

Use Rescue Mode. Enter bootloader by holding down Power + Vol Down while it was turned off, then use your volume keys to navigate to Rescue Mode. Then, go to https://pixelrepair.withgoogle.com/ and continue from there.
thanku for reply sean .. i tried rescue mode but when i choose nd to click rescue mode it atomatic comes only fastboot mode nd i cant flash or boot any img file or zip file

The point of Rescue Mode is to update the existing Android installation to a newer version. In this case of yours, your phone does not detect any valid OS, which is now pretty impossible if you want to install a fresh Android installation. Can you at least try to boot into Recovery mode?
thankss sean.. and no recovery mode opening only fastboot
only when i try to chose any other option for recovery rescue or any other it not opening only fastboot and barcode is opening this happened when i flash custom rom on both slot and flash stock rom on one slot and relocked bootloader my biggest mistake was this after all this my phone is not booting
The only last resort for you now is to contact Google Support, or go to a nearby Google Store for assistance. Since you custom'ed' ROM it, your warranty is now voided. If you still want to try fix it yourself, ask ChatGPT or Google for help :-(
ok iam going to give it to a shop or ill return my phone it has 1 years of waranty

if you can get into fastboot mode, I might try PixelRepair tool from Google, but there's a chance it'll format/wipe data...so be aware of that...
nevermind...didn't read fully...overlooked that you relocked bootloader...this is a time old tale of hard bricking device when relocking bootloader -- for next time (and for anyone considering it), the best way to do it is to use Google's official Android Flash Tool as it is from Google so you know it follows proper protocol to not hardbrick your device when relocking bootloader...
i can access fastboot mode but nothing help because of bootloader locked nd debugging is also disabled :'(

Your last chance is sideloading an OTA -- you don't need usb debugging or unlocked bootloader to do that. But it's a stretch as you locked the bootloader without flashing factory images on both slots which usually results in hard-bricks.
