So when I try to install TWRP (for Lineago OS) I was getting the "fastboot_init" screen and wasn't able to pass it. After some research I found out that my software may be the issue, so to turn the normal state of my phone I flashed this kdz file with LG Flash Tool 2014 in Download Mode.
After that, I booted. I was able to hear the constant starting song with black screen right after I saw the LG logo. After restarting the phone, I'm only able to see charging info and a red light when I plug a usb.
Notes:
- I tried to force restart with Power + Volume Up combination.
- First photo is not mine (shows the same thing)
Problem solved. Try the keyword "soft bricked".
Note that you enter the download mode if you, unplug battery & USB and press Volume Up connect the usb that you attached it to a PC.

Hi guys, so my problem is I was installing a new rom on my rooted D855. everything was going along fine but then the process stalled. I left it running for 15 - 20 minutes but it was still on 33%. I tried holding the power button in desperation which shut the thing down. Now when I try to factory reset it goes to the prompt screen, I answer yes, then it asks me to confirm. from there however it goes to LG splash screen and eventually a black screen with Fastboot mode started. -reset- portcharge -reset- portcharge fastboot: processing commands in the top left corner. That's it.. If I try download mode it goes to the download screen and then to the black screen as described above.
Sounds pretty ordinary but if there is an answer out there I am sure one of you guys will know it.
TIA
i had some similar other issue and the only way i got out of it, is by using the lg flashtool 2014 and the KDZ file appropriate to your version
there is a thread with a step by step instructions.
you launch the flashtool, then insert the kdz file (original stock rom) then you put your phone into download mode (making sure in windows/controlpanel/devicemanager/ports - comp port 41 for the device driver)
you press volume up and plug it into the pc, the pc sees the phone and it starts reflashing the custom rom to your cell.
i presume that as soon as your download mode is working by flashing whatever command is corrupt and makes your phone black should be bypassed by then
i hope it helps - look for the thread how to flash the lg
Thanks I'll give it a shot. Not sure device manager is seeing it properly. I'll have a play and see. Thanks again for the reply
O.K here's the thing, my phone is seen in device manager as a Samsung Android Phone. Under the details tab it shows it connected via USB Modem Phone ADB Port. There is no option to change the port to 41. Anybody who can help I would be very grateful......
Hi all, I've been using XDA for years since the original O2 XDA's and I have never had to post anything as I've always found my solution. I'm hoping somebody can assist me with a problem I have on this stock galaxy tab 3.
The device was brought to me after being thrown down the stairs. I replaced the screen and built it back up,
Removed battery connector and reconnected = nothing happens
Press power = nothing happens
press download mode = nothing happens
press recovery mode = nothing happens
Plug USB into PC = nothing happens on PC or tablet
Plug in USB mains charger and it displays battery charging logo but it doesn't fill or animate the fill then it starts the samsung boot screen. It reboots and continues to do this constantly and never ends.
I've tried two batteries and both batteries work in another tab 3 but neither batteries changed how the device works.
Thank you for any advice in advanced!!
I just received a Tab 3 lite (SM-T110) for repair, it's having a similar problem.
It does automatically turn on when plugged into charger or computer.. It is stuck on a bootloop, requiesting a Kies recovery. It does reboot when given the three finger salute (center button, volume down, and power) - it will not enter recovery mode though - same firmware error message). The device is also full off or full on, no indication of it's it's recharging or no - let the battery run out, it's off - else it's on (does not turn on or off with power button). I don't have any info how it got into this state - most likely power loss during a firmware update, but haven't ruled out other possibilities (ie bad rooting job, a custom ROM upgrade went wrong, etc). I'm not 100% concerned about cause, but hopefully I can unbrick the thing.
Anyways, I loaded Kies onto my computer and put it into recovery mode and plugged it in - nothing. Exit the recovery mode of Kies, and all of a sudden the program goes nuts trying to connect and disconnect from the device. Hmm... Okay, disconnect it, uninstall Kies, install Kies3 and try again - same thing except it complains the device is too old when the program leaves recovery mode - but same thing otherwise - does not show up in recovery mode, connects and disconnects at huge rate when not in recovery mode....
Hmmm...
Now looking at the screen, it does indicate (in the upper left hand corner) that it's in ODIN mode... So my next step I figure I'll try ODIN (although I'm researching ODIN at the moment as I haven't used it before (never had to unbrick anything from Samsung prior to now).
Okay, that was painless - downloaded and installed ODIN 3.10.7, and then downloaded the latest firmware from Samsung, extracted the firmware, added it to ODIN's AP line, then hit start to push the latest firmware onto the tablet. Good as new again.
Hi, it's my first time posting here as I was unable to find a solution looking at similar threads.
Anyways, I was trying to install another ROM on the G4 but I think I messed up deleted everything entirely and got bootlop and reboot. I'm not exactly sure what I was doing as I'm new to these things.
What leads me to believe that this is not a hardware issue (as widely covered) is that during the bootloop, there's a tiny little green android in the middle of the screen with a small 3D box on belly.
When trying to solve this issue, I've tried:
Volume Up + Power to enter Download Mode
Nothing happens - back to the green droid
Volume Up + Power + USB to computer to enter Download Mode
Nothing happens - back to the green droid
Volume Up ONLY + USB to computer to enter Download Mode
Goes in Download Mode for a few seconds, but then goes back to the green droid
Volume Down + Power to enter Recovery Mode
Nothing happens - back to the green droid
Volume Down + Power to enter Hard Reset Mode
Allows me to factory reset, but then back to the green droid and bootloop
Connecting the G4 to the computer to see if phone would be available in device manager -
Not found
Nothing I've tried seems to shake off the little green android.
The phone doesn't connect to the computer at all.
Here's a video: youtu(dot)be/MfnkhZTPOz0
The top left of the G4 says "Bootloader State : Bootloader Unlocked!"
Here's a clearer image of the green android: android-hilfe(dot)de/attachments/2012-09-22-03-41-16-jpg.124036
Any suggestions?

From the thread you gave me it says 'YOU GET QHSUSB BULK MODE IN DEVICE MANAGER THEN INSTALL QUALCOMM DRIVER'.
But unfortunately, when I connect my G4 to the computer, it does not register 'QHSUSB_BULK'. In fact, it does nothing at all. The phone keeps rebooting and the computer does not detect.
So I cannot get either 'QUALCOMM HS-USB 9008' or 'QUALCOMM HS-USB 9006'.

Hello everyone,
so here's my problem:
Wednesday morning i took my phone out of my pocket and had a blackscreen. I tried to restart it and took out the batterie but i always got stuck in the LG Logo or a bootloop. Since i had TWRP and lineage OS installed, i tried to go into the twrp menu with the factory mode (power button + volume down) but after the "double yes" i always got a blackscreen.
So i went into the internet to fix it myself. I tried the "LG Flash Tool 2014" with the kdz. reset & the other Flash tool with the tot. reset. Both didnt recognize my phone. At this point, the only thing that worked was the download mode BUT not the recovery mode that usually comes after it. It just showed the download mode for some seconds and then a black screen. Later i noticed that my phone showed as a "qualcomm device" in the device manager, and the internet said that this was bad. So i used "Board diag" and "Smart boot diag" to fix it, but at the point where the device should have restarted, and the download mode should have worked WITH the recovery mode, i always ONLY had the 6 second download mode. After messing a bit with "Board Diag" i even got it to show up as LGE AndroidNet USB Serial Port in the device manager, which apparently was even more bad and only way to go back to qualcomm was to shorten the pins which i did. And it worked BUT now i was back with the qualcomm stuff.
So as you can see, i've prety much run i circles since wednesday... Iam now at a point where 3 different thingscan happen when I try to put my LG into download mode (volume up + usb cable):
1. Its recognized as a unknown device which is constantly connecting and diconnecting, so iam assuming my phone is bootlooping with a black screen.
2. The download mode icon shows on my phone and disappears after some seconds but my pc fails to recognize it.
3. Nothing happens and the screen stays black
When i only connect the usb cable, it shows a stuck charging icon for some seconds and then goes black. Connecting without a battery shows the "missing battery icon". I tried with 2 pc's, both having the LG mobile driver 4.2 and the qualcomm driver installed AND beeing in testmode. Both don't recognize the device. I also tried 2 batteries on my phone but it changes nothing.
I have a D855. And i know that my situation is pretty f*cked but maybe someone i able to help me anyway. Thanks alot.
Hi everybody, yesterday I was playing with my old Galaxy A50 trying to install a custom rom unsuccessfully.
I repeated the procedure three times installing TWRP and then Havoc OS but every time I tried to reboot from TWRP to OS I was stuck at the warning screen saying that the phone bootloader was unlocked and booting into download mode to reflash TWRP was blocked as it showed "only official binaries can be installed" (yes I installed Samsung disabler but still).
Still I was able to get the phone into download mode and reinstall the stock firmware as it seemed to be the only way to install and boot TWRP.
But at 4th time repeating the process I got frustrated, shut down the computer and left the phone on the warning screen still connected to computer usb cable.
Then I got back and noticed the phone was off as the battery died.
Indeed the battery died, so I put the phone in charging and after it reached 100% I tried to boot into download mode again to reflash stock firmware.
But here's the strange thing, I cannot boot into download mode anymore as pressing vol up+vol down while connecting usb cable, shows the lightning charge logo for 5 secs and then reboots infinitely with the same pattern.
If I force reboot by pressing vol down+power it shows the Samsung logo with the warning below it, then skips to another screen with another warning suggesting to press power button to continue (which does nothing) and after a while reboots to samsung logo.
So it doesn't seem it is bricked, it looks more like a battery controller fault, so I tried to detach the battery flex from the board, hoping it would reset the controller but it's still the same.
Also I tried with the flex detached and still no download mode is possible.
Was the download mode somehow erased? (if it's even possible considering it's the motherboard firmware)
If you need photos, videos or even a call on zoom, Skype, webex I would be glad to show you
same i got the same problem i can't find nothing for this when i press volume up and down and put the otg cable its simply charges but it gets stuck on the logo image there's no way to fix this but the only way is to open the phone,change the emmc and put one from samsung,close the phone flash a custom rom and you are done.
If you can enter recovery, do it. As soon as your phone gets into it, select the power off variant and then try to enter the download mode.
It seems like you did not unlock the bootloader, did you?
The bootloader Is unlocked i can't enter in the recovery because the phone locks on charging logo and its fully charged but when i try without charger It doesn't start.
